Five applications of machine vision inspection technology in industrial automation

describe

Machine vision inspection technology is a new inspection technology based on computer vision research. In today's continuous development of industrial automation, machine vision technology has been more and more widely used in industry, and more and more recognized and favored by users. Therefore, people began to consider using CCD cameras to capture images and send them to computers or special image processing modules. Through digital processing, the size, shape and color can be determined according to pixel distribution, brightness, color and other information. This method combines the rapidity and repeatability of computer processing with the highly intelligent and abstract ability of human vision, thus generating the concept of machine vision inspection technology.

It is not difficult to find that its application scale is more and more common. According to these categories, we can sum up five major applications in industrial automation.

1. Visual guidance and positioning application

Visual positioning requires that the machine vision system can quickly and accurately find the measured parts and confirm their positions, and machine vision is used to position the loading and unloading to guide the robot to grasp accurately. In the field of semiconductor packaging, the device needs to adjust the pickup head according to the chip position information obtained by machine vision, pick up the chip accurately and bind it, which is the most basic application of visual 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 is necessary to accurately pick up chips and bind them, which is why visual positioning has become the most basic application in the field of machine vision industry.

2. Application of appearance defect detection

To detect whether there are quality problems in the products on the production line, which is also the link that replaces the most manpower. For example, in the medical field involved in machine vision, its main detection includes size detection, bottle body appearance defect detection, bottle shoulder defect detection, bottle mouth detection, etc. With the development of modern industrial automation, machine vision inspection is widely used in various inspections, measurements and parts recognition, such as new energy power battery surface defect detection, electronic component recognition, magnetic material appearance defect detection, bar code and character recognition on product packaging, etc. The common feature of such applications is continuous mass production and very 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, scrap low-quality products at the early stage of the production process, thereby reducing waste and saving costs.

3. High precision detection application

The precision of some products is relatively high, reaching 0.01~0.02m or even to U level, which cannot be detected by human eyes and must be completed by machine. The most typical cases are power battery burr detection, pcb circuit board detection, etc. As well as medical glass bottle detection, the medical field is also one of the main application fields of machine vision.

4. Image recognition application

Image recognition is to use machine vision to process, analyze and understand images, so as to identify various targets and objects of different patterns. 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 two-dimensional code recognition. QR code and barcode are very common in our life. In the production of goods, manufacturers store a lot of data in small two-dimensional codes to manage and trace products in this way. With the application of machine vision image recognition becoming more and more extensive, the bar codes on surfaces of various materials become very easy to be recognized, read and detected, thus improving the level of modernization, greatly improving production efficiency, and gradually reducing production costs.

5. Object sorting application

In the machine vision application link, the object sorting application is a link established after recognition and detection. The image is processed through the machine vision system, and the product sorting is realized by combining the use of mechanical arm. In the past, on the production line, the materials were manually placed at the designated location before the next process. Now, automatic equipment is used to divide materials, in which machine vision system is used to capture and analyze product images, output results, and then robot is used to place the corresponding materials in a fixed position, so as to achieve intelligent, modern and automatic industrial production. It is often used for food sorting, express active sorting, cotton fiber sorting, etc. 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 techniques will help enterprises to remain invincible in the fierce competition.
