In the process of realizing automatic production, the "figure" of machine vision inspection equipment will always be found. Machine vision detection technology can transmit the image information obtained by CCD camera to the computer for analysis and judgment, which is a combination of highly intelligent and abstract ability of human vision. In the actual production process, what important role does visual inspection technology play? Let's make an inventory.
Visual guidance and positioning application
Visual positioning requires that the machine vision system can quickly and accurately find the measured part and confirm its position, and use machine vision to position the loading and unloading to guide the manipulator to accurately grasp. In the field of semiconductor packaging, the equipment needs to adjust the pickup head according to the chip position information obtained by machine vision, accurately pick up the chip and bind it, which is the most basic application of vision positioning in the field of machine vision industry.
In addition, in the field of semiconductor manufacturing, the chip position information adjustment pickup is very difficult to handle, and machine vision can solve this problem, because it needs to accurately pick up the chip and bind, which is also the reason why vision positioning has become the most basic application in the field of machine vision industry.
Appearance defect detection application
With the development of modern industrial automation, machine vision inspection has been widely used in various inspections, measurements and parts identification, such as surface defect detection of new energy power batteries, electronic component identification, magnetic material appearance defect detection, bar code and character recognition on product packaging, etc. The common characteristics of these applications are continuous mass production and high requirements for appearance quality. With the improvement of economic level, machine vision inspection has been paid more and more attention. It can improve the production capacity of qualified products and scrap inferior products at the early stage of the production process, thus reducing waste and saving costs.
Check whether the products on the production line have quality problems, which is also the link that replaces the most manual work. For example, machine vision involves the medical field, and its main detection includes size detection, bottle body appearance defect detection, bottle shoulder defect detection, bottle mouth detection, etc.
High-precision detection application
Some products have high precision, up to 0.01~0.02m or even to level u, and cannot be detected by human eyes, which must be completed by machine. The most typical cases are power battery burr detection, pcb circuit board detection, etc. As well as the detection of medical glass bottles, the medical field is also one of the main application fields of machine vision.
Image recognition application
Image recognition is the use of machine vision to process, analyze and understand images to identify different patterns of objects and objects. It can trace and collect data, and is widely used in new energy batteries, circuit boards, electronic components, hardware accessories, food, medicine and other fields. The most typical case is to identify the QR code. QR code and barcode are very common barcodes in our life. In the production of goods, the manufacturer stores a lot of data in a small two-dimensional code. Through this way, the product is managed and traced. As the application of machine vision image recognition becomes more and more extensive, the barcode on the surface of various materials becomes very easy to be recognized, read and detected, thus improving the level of modernization, greatly improving production efficiency, and gradually reducing production costs.
Object sorting application
In the application of machine vision, the object sorting application is a link established after recognition and detection. The image is processed by the machine vision system, and the product sorting is realized by combining the use of the mechanical arm. In the past production line, materials were placed at the designated place manually, and then the next process was carried out. Now, automatic equipment is used for material distribution, in which the machine vision system is used for product image capture, image analysis, output results, and then the corresponding materials are placed in a fixed position through the robot, so as to realize the intelligent, modern and automatic industrial production.
With the rapid development of China's manufacturing industry, enterprises' demand for machine vision will gradually increase. Saving labor, improving speed and improving product quality have become the only way for enterprises to survive in the current economic situation. The application of machine vision detection technology will help enterprises to remain invincible in the fierce competition.
