We have to admit that the high automation of machine vision inspection system plays a very important role in industrial production. Visual inspection technology and industrial automation promote each other, and the promotion of visual technology is highly integrated. Machine vision detection technology is an attempt to establish an artificial intelligence recognition system to obtain "required information" from images or multidimensional data. So, how is machine vision seamless in industrial automation production?
Image recognition is an image capture device, which converts the captured object into image information. In the special image processing system, according to the distribution of pixels, brightness and color information, into digital signals, the image system in these signals for various operations to extract the characteristics of the target, and then according to the judgment results to control the field equipment to carry out a series of operations.
Two dimensional code and bar code are very common bar codes in our life. In the production of goods, manufacturers store a lot of data in a small two-dimensional code, and manage and trace the products in this way. With the application of machine vision image recognition becoming more and more extensive, bar codes on the surface of various materials become very easy to be identified, read and detected, so as to improve the level of modernization, greatly improve the production efficiency, and gradually increase the production cost Lower.
Visual positioning can accurately detect the product and confirm its position.
The most typical case is in the field of semiconductor manufacturing. The pick-up head for chip position information adjustment is very difficult to process. Machine vision can solve this problem because it requires accurate chip picking and binding. This is also the reason why visual positioning has become the most basic application in machine vision industry.
The biggest characteristic of machine vision industrial application is its non-contact measurement technology. Because of non-contact and non-wear, it can avoid the secondary damage caused by contact measurement.
Machine vision is to make mechanical equipment have the ability of "seeing", just like people can see things with eyes. Machine vision does not need to touch the product like traditional manual, but it has many high-precision and high-speed performance. It not only has no abrasion on the product, but also solves the possibility of secondary damage to the product, which has a particularly significant improvement on the manufacturing level of precision instruments. The measurement of Luoding thread, twist drill, IC component pin, car parts and connectors is a very common measurement application.
Manual visual inspection often encounter many problems, such as low accuracy, easy to have errors, can not work continuously and easy to fatigue, and time-consuming and laborious. With the extensive application of machine vision, the production and detection of products are highly automated.
The most typical cases are coin character detection, circuit board detection and so on. As well as the detection of RMB coinage technology, the accuracy requirements are particularly high, the detection equipment is also many, the process is complex. In addition, there are positioning detection of machine vision, whether the production of beverage bottle cap is qualified or not, whether there are problems, as well as the detection and recognition of barcode characters of products, the defect detection of glass bottles, and the detection of medicinal glass bottles. The medical field is also one of the main application fields of machine vision.
In the application of machine vision, the application of object sorting is established after recognition and detection. The image is processed by machine vision system, and the product sorting is realized with the use of mechanical arm.
The most typical case is in the past production line, the material is placed in the injection molding machine manually, and then the next process is carried out. Now we are using automatic equipment to separate materials, in which the machine vision system is used to capture and analyze the product image, output the results, and then put the corresponding materials in a fixed position through the robot, so as to realize the intelligent, modern and automatic industrial production.
Through the field application of machine vision inspection system, production enterprises at all levels can not only monitor the production quality of products in real time, but also greatly save labor costs. It is the best choice for manufacturing industry in the era of industry 4.0. In order to improve the quality and maintain competitiveness, it is imperative to carry out visual inspection and high automation in various fields.
