Today we will talking about basic principle of visual inspection machine: visual comparison.Sipotek Visual Inspection Machine 26

Automatic Screw Fastening Machine

Sipotek Visual Inspection Machine 26

All existing elements have an idea that is considered as fundamental, and that allows the development and growth of these based on it.

Each science was created under a premise that surrounds a fundamental idea, and from there more and more functions and content related to it were developed, sharing the origin of everything. It also happens with the functions of certain machines, they are created under a basic principle and then specialize in certain things.

Visual inspection machines also have their fundamental principle: visualize one element and compare it with another.

visual inspection machine is not exempt from this principle, so we can say that it has a fundamental idea, which is related (more than with observation), with the comparison of two elements to generate a response or result.

The vision inspection system manufacturers know that making the comparison work exactly, is what will make the visual inspection machine work and be reliable, that is why they put special attention in making the machine could observe every detail.

This is necessary since information is needed to classify all the elements present in the inspection.

In order for the visual inspection machine to determine which elements will pass the comparison and which not, it must have a kind of guidance, a focal point at which the vision inspection system manufacturers tell you what could be right and what should be discarded. For this, they have created a program that clearly shows the cases in which the object that is being studied should be discarded.

The system must include images of those previous tests that have been considered successful.

In order to be able to show the visual inspection machine the cases of ideal elements, it must be included in the system, visually and also through information of another class, which would be the elements to be classified and those that will pass the tests satisfactorily. Those elements that are included through images will serve as a guide to be able to compare all the others, as stated earlier this is the visual comparison.

A visual comparison takes place when placing an element next to another, observing them from different angles and being able to generate a kind of relationship between them. The characteristics to be compared must be viewed from different angles, first to make them coincide in their position and to be able to make the comparison in a better way, or it can also be achieved through the recreation of the images in a 3D format , superimposing one with the other and detailing the differences (considerable or not).

This is one of the reasons why vision inspection system manufacturers include a considerable amount of sensors and cameras in visual inspection machines, since they need to have a complete visual of the objects that leave the production lines, since some may be in a position and have a different meaning to the image included and classified as ideal. Being able to place at the correct angle, the visual comparison will start quickly.

7 Popular Machine Vision Systems and Accessories by solution Providers in China

Quality control can mean a lot of things, and in the context of machine vision, it most often refers to the overseeing of proper sorting of goods on a production line and inspection of goods and parts. Machine vision systems that assess products based the quality of shape, size, material, or any other programmed factor include vision inspection systems, optical inspection systems, and laser inspection systems. All do so with consistency, speed, repetition, and magnification.

In terms of inspecting products for quality, two of the biggest fields that employ machine vision systems are the electronics industry and the automotive industry. Within these industries, manufacturers make especially great usage out of AGV (automated guided vehicle) equipment to inspect their products.

As well as inspecting finished products, these industries use machine vision systems to inspect the parts used to make machine vision products themselves. Such parts and components include die casts, molds, and tools. Machine vision solutions routinely inspect them under high magnification. Another focus of machine vision system is human safety and security.

visual inspection machine

There are 7 types of machine vision systems

  1. Optical inspection system use machine vision to inspect objects and images like serial numbers on products at a store checkout line, and finished products on an assembly line.
  2. Optical sorting systems work like optical inspection systems, except their goal is to sort products.
  3. Laser inspection systems perform machine vision applications using a combination of laser beams and photoelectric sensors. Uniquely, after scanning an image or item, they can generate a 3D reproduction. Laser inspection systems can inspect images and items for a wide range of applications, like parts counting, product defect detection (down to the microscopic level), serial number scanning, and barcode scanning.
  4. Smart cameras obtain extra high-quality images using a combination of processing circuitry and imaging software. They are portable, but because they don’t come with much storage space, users usually use them in conjunction with a main system.
  5. CCD cameras convert photons into electrical or digital images using CCD chips, or charge-coupled device chips. Once the machine vision cameras have converted the photons into images, operators can upload said images onto a computer image file.
  6. Magnetic imaging systems are designed using magnetic materials. They develop visual representations of products using their magnetism, along with an x-ray type sensor.
  7. Robotic vision systems are machine vehicles, like AGVs, that traverse an industrial space. They are semi-autonomous and move using limited sight provided to them by computer vision.

Machine vision inspection equipment is mainly used for quality inspection in industrial products. Compared with human inspection by naked eye detecting, machine vision inspection equipment can be used to accurately and quickly distinguish defective products and qualified products. The accuracy rate almost reaches 100%. It helps increasing production yields at he same time effectively guarantee the quality of the products.

MACHINE VISION CAMERAS INSPECTION SYSTEM: HOW CAN THEY BE USEFUL FOR MANUFACTURING UNITS?

The electronics industry is at its boom with new technologies being created every day and the most important thing about the electronics industry is that the appliances and machines are becoming smaller with each passing day. Now that the machines are becoming smaller, parts are also taking the same route. All this has increased the efficiency of the appliances, but has also created the problem of not being able to inspect the small and micro parts.

machine vision inspeciton system manufacturers

This is where machine vision systems have become crucial in industries. Using these systems, you can check and inspect the machine parts with higher reliability. High-quality machine vision cameras can click pictures of the small component at an effective frame rate and resolution. These systems are now helpful in assembly verification, selection of parts and final inspection as well.

Some of the advantages of using the machines vision cameras and systems are:

Cost reduction

These systems and cameras are helpful at every stage of manufacturing like inspection and selling the parts and finally assembling them as well. This makes the processes more improved in every way. You can reduce the scrap generation, wastage of materials, speedy manufacturing and also reducing the cost regarding manual labor. All this will be helpful in effectively reducing the cost of production of a company.

Accuracy

Machine manufacturing is not an easy task as hundreds of small components need to be placed in the right place for an appliance to work. However, placing them and assembling complex machinery can be difficult at times as there are chances of human error. If a small thing misses through a human eye, then a unit may have to bear future losses. However, with machine vision cameras, this problem is solved entirely. The parts are tested and inspected thoroughly using the camera high resolution captures. The cameras can identify and capture almost any kind of component keeping in mind the lighting, temperature, optics, etc. which can be missed by a human eye.

Safety

There can be many manufacturing units which can be hazardous to humans and can also lead to accidents and mishaps. However, to reduce such situations, the manufacturing industry is installing machine vision systems to reduce such accidents by lessening human involvement in risky manufacturing processes. These cameras can take care of the robotic assembly automatically, thus reducing any kind of risk during operation.

Reduce downtime

Machine vision cameras are capable of recognizing the damaged parts beforehand only and thus one can reduce the downtime of the manufacturing processes effectively. It also makes sure that the parts are not damaged due to assembly fault, thus making the process cost and time efficient.

A good machine vision camera can change the way manufacturing units operate by saving time and every other resource. It enhances the reliability and accuracy with larger field views, proper inspection, and real-time processing to avoid any kind of manufacturing mistakes. This technology is slowly transforming the entire industry by increasing productivity and reducing the risks and losses.

Machine vision cameras inspect heads up display in aerospace industry

Heads-up Displays (HUDs) for the latest generation jet fighters encase advanced optical components within precision machined aluminium castings. At a leading UK manufacturer, these specialised units are designed, manufactured, assembled and calibrated by highly skilled technicians. Due to the number of operations required in this process, final inspection is mandatory to ensure that all the assembly tasks have been completed before the unit is shipped to the customer for integration into the aircraft.
To automate this final inspection process, Sipotek has developed a vision-based system that eliminates any human error associated with this task (Figure 1). In developing the system, a major goal was to provide a standardized inspection that provides objective results with minimal operator input.

Vision inspection
Vision inspection tasks were split into two categories: simple surface level inspections such as the presence of various screws, bolts or covers and more intricate inspections that require precise lighting and camera setups to determine pass/fail criteria.

The challenge posed by the simpler inspections was not the difficulty of assessing the image against a pass/fail criterion, but the number and variety of inspections that needed to be performed across the six surfaces of the HUD unit. This was achieved by splitting the inspection process into two parts. The first part required the operator to place the HUD upside down into a nest to allow three of the faces to be inspected.

To perform inspection of the HUD, the system incorporates a gantry of cameras mounted on a linear drive that move in the z axis (Figure 2).  The laser projection unit is mounted in-line with the camera to allow a single laser line to be projected into the machined holes on the HUD. In addition white LED lighting arrays were mounted above the camera to provide overall diffused lighting for surface inspection checks. The nest was mounted on two linear drives allowing it to travel in both the x and y axes. Using this setup, any point on the three inspection faces could be presented to a camera and light module for inspection.

Once the system has indexed around all the inspection positions on the three presented sides, the nest is returned to the front of the machine, at which point an operator is alerted to position the HUD in an upright position. After the quick release tooling is changed and the unit reloaded, the machine continues to inspect the remaining positions before returning the HUD to the load/unload position.

The machine control and human machine interface (HMI) required the user to adjust positions, configure new inspection areas and new nests for future variants without the user requiring access to the machine code. This resulted in a layout capable of displaying the key data in a clear format during inspection and providing a large number of diagnostic and configuration tools and pages accessible from the various secure menus.

Complex tasks
More complex inspections required on the HUD primarily comprised of verifying that holes had helically wound, precision formed coils of stainless steel (known as helicoils) inserted into them. To add complexity, the holes also had a shoulder part down the bore before the helicoil so differentiation was required between the shoulder and helicoil surface.
To ensure the helicoils were in-place, vision inspection is performed using a combination of an IVS LED area light and an angled laser setup (660nm 20mW modulation laser projector) to illuminate the surfaces perpendicular to the axis of the hole. Using the area light, an initial image was first captured by an IVS gigabit Ethernet camera and thresholding used to locate the hole in the image. By computing the geometry of this thresholded image, small edge deviations created by any debris or swarf residing around the perimeter of the center of the hole are ignored by the vision system.

A second image, captured as the laser line is projected across the hole, is then used to search within a toroid shaped area for the presence of reflections from the helicoil surface. By using the position determined from the first image, this check can accurately account for any movement of the hole relative to the center of the image, potentially caused by the accuracy of the linear drives or variations in the HUD units and load positions on the nest.
The inspection requirement at the individual positions, whether it was to check for the presence of a bolt, cover plate or helicoil, generally required a very small field of view. This was achieved using IVS 1296 x 966 pixel CCD GigE cameras with a fixed field of view and focal distance. This approach dictated a fixed distance between cameras and part and therefore required the systems programmable logic controller (PLC) to precisely position the x, y and z axes to ensure the object of interest was located in the centre of the field of view and was in focus.

The inspection of the HUD units also required a small number of imaging functions to be performed on larger objects. These included verifying that the correct labels were applied and capture an overview image of the unit that is archived for future reference. This requirement was met using a pan-tilt-zoom (PTZ) camera capable of capturing images ranging in size from an overview of the full 600mm long unit down to a 70mm wide area of interest (Figure 3). The IVS PTZ camera, along with the GigE cameras, structured lighting and precision laser lines were all controlled by IVS software, a PC based machine vision application.

Final results
Such a complex array of inspection positions and requirements presented a further challenge in terms of displaying the final results to the operator in a usable format. Individual results for each position were collated into a report format that is automatically printed once the inspection has completed. The system also presents the data on a monitor in graphical form for the operator to visualize which tests have passed and which have failed. An overview screen shows the operator the results of groups of related types of checks for all faces of the HUD (Figure 4).  If further detail is required, the operator can access additional screens of each individual face with every inspection result relating to that face displayed in a colour coded layout.

Due to the immense value of the HUD units and the fact that they are made to order, only two units were available to configure the machine. Following the installation, IVS and the manufacturer worked together to refine the vision program as production parts were run through the machine to take account of the natural variation in factors such as material finishes and colors. This was performed by remotely accessing the vision system by IVS engineers.
The HUD inspection machine has automated a long list of visual checks while allowing the operator to complete other tasks while the inspection is running. The elimination of human error and subjectivity has led to a higher quality of parts leaving the factory and the ability to keep a visual archive of every product produced.

Through human load on pallet, the servo module feeds, pallet on the left do the inspection, then pallet on the right will be unload, and feed again on the right pallet, so as to achieve alternating feeding inspection.

1.3 Image Acquisition Mechanism

Picture 1-3 is the image acquisition mechanism. When products on the pallet are moved by servo module to specific position for image acquisition, the camera will be triggered to capture images by different light sources. The image-captured data will be transferred to upside software system and do the processing with results, which will be transmitted to downside Plc control servo Z module with a suction nozzle to sort the OK and NG products.

1.4 Downside Control System

Picture 1-4 shows the downside control system with relevant devices, including Plc controller, servo motor drive, host, power, servo motor, etc.

As shown on the picture, in the adjustment procedure, the whole system deliver relevant signal from upside control system to the down side Plc, so as to adjust accordingly to the servo module motion ( motion position quantity and position, image capture position, running speed, running time, NG position shift).

In the course of system running, pressing start button on downside left and right, the plc will receive the start signal and control the servo module motion. When the module move to position for camera image capturing, the plc send capturing signals to image processing system, which sends the electric signal and controls multiple light sources and lights up them one by one. After inspection result is defined, it will be transferred to downside plc. After finishing inspection for one side pallet and getting the NG information, the system controls module and rejects NG products by a cylinder control.

Above mentioned is a brief introduction of our current servo pallet inspection machine on structure and process aspects.

  1. Software Functions

Currently the servo pallet inspection machine can do the following inspections:

  • Circle dimension measurement (Inner and outside diameters and balance, thickness);
  • Line to line distance (Suitable to measure regular rectangles in the length, height, width, step and step width);
  • Dot to dot distance (Suitable to measure burrsize, dot to dot size);
  • Area measurement (Suitable to measure specific area of parts,decide good or not);
  • Positioning (Suitable to detect relative position relationships of parts)
  • Defective inspection (Suitable for surface defects, scratches and trace);
  • Compare function (Set the template based on good partsto match quality of the inspected parts);
  • OCR recognition (Suitable for different character recognition);
  • Angle measurement (Suitable for appropriate angle between edges);
  • Template matching (Suitable to use the well-established template to search the same part of the images and output the number and position);
  • Inner and outer edges detection (Distinguish inner and outer edges of the parts);
  • Block positioning (Position fixed section and measure the dimensions);
  • Functions combination (Above mentioned functions can be combined to achieve multiple inspection and measurement task).

Details above are the functions of our current servo pallet inspection machine. Some functions can be achieved by using the above mentioned software system. Including dimensional measurement (Circle inner and outer diameter, regular circle length/width, step height, step width), screw inner and outer dimension measurement, gearwheel/gear head/circle thread/root measurement, burrs inspection, surface dust, product completion detection (edge broken, part missing), surface scratches detection, character recognition, character inspection and etc.

Through our inspection software system with combination of these functions, servo pallet inspection machine can achieve more functions on images-processing, inspection, measurement and recognition.

What is the role of flow analysis in injection moulds

In the process of mould making, it is very important and difficult to find the position of flow balance in the design of runner. In the past, it is often necessary to design runners through past experience to achieve the goal of flow balance, so it needs continuous practice to find solutions, which will lead to longer product development time and increased cost. Mould flow analysis can assist runner design, shorten product development time and find potential problems easily, so as to improve product quality and achieve the goal of reducing costs.

Understanding Potential Problems of Injection Mould

Mould flow analysis can predict the position and quantity of glue feeding point from the basic position of bonding line, and save cost by improving the quality of parts, eliminating downtime and reducing cycle time and waste rate. Flow simulation helps to improve product design by reducing or eliminating conditions that may lead to gas defects, burns, dents, voids or excessive warpage. This is achieved by optimizing such factors as gate size and location, runner balance in multi-cavity tools, material selection and process conditions. This technology can identify potential problems in injection moulds before problems occur.

Mould flow analysis will help to avoid potential problems in Moulds

Competition in today’s market requires suppliers to improve quality while reducing costs. Mould flow analysis enables die manufacturers to reduce manufacturing costs, delivery time and parts costs.

In addition to identifying and eliminating potential problems, mouldflow analysis can also help optimize the overall part and mould design, while preventing over-engineering.

This happens when too much effort is put into part/mould design. Design often becomes more complex and uses more plastics than is necessary. Mould flow analysis can prevent unnecessary overengineering. Today’s technology allows die manufacturers to evaluate different cooling designs to reduce flow rates and optimize temperature distribution across parts and moulds, minimizing differential shrinkage, warpage and cycle time.
