Size Detection and Application of Machine Vision Inspection Technology
In the manufacturing industry, appearance and size detection is really important part. Before on sales, each product may go through hundreds of different appearance and size detection processes from the initial materials, parts to the final finished products. Appearance and size detection requires high labor cost, but the inspection efficiency and final effect may not be satisfactory. Therefore, more and more factories begin to adopt visual inspection equipment to detect the appearance and size of products.
Vision inspection technology has the advantages of low cost, high precision, high efficiency and convenient operation and be able to effectively solve the problems that traditional detection methods can’t deal with. At the same time, vision inspection technology widely applied in the automatic manufacturing industry to inspect various size parameters of products, such as length measurement, circle measurement, angle measurement, radian measurement, area measurement, etc. Let's talk about appearance and size detection in vision inspection technology.
1. Definition of size detection
Size detection is to inspect whether the product size is within the tolerance range based on the drawing, so as to find the error of shape and size. In addition, the accuracy of machining datum position, machining allowance distribution and wall thickness deviation can be carefully detected.
2. Methods of size detection
The actual size of the product is often an indispensable parameter, but it may not be available due to the complexity of the object surface or the limitations of objective physical conditions. Vision detection technology can deal with such problems well. In the traditional automatic production, the typical method of size detection is to use micrometer, vernier caliper, feeler gauge and other naked eyes to measure, which has low measurement accuracy and slow speed, and can not meet the needs of large-scale automatic production.
Vision inspection technology is a kind of non-contact detection method, which has the advantages of high detection accuracy, high speed, low cost, convenient installation and so on. It can detect parts of various sizes, such as length, height, width, circle, R angle, multi-stage height, etc.
3. Application of size detection
Electronic components, automotive parts, mobile phone parts, nuts, hardware, magnetic materials, plastic, ceramics, buttons and other composite material components, magnesium, aluminum and their alloy parts can be inspected by machine vision inspection technology.
Compared with traditional product inspection methods, machine vision inspection technology has the characteristics of objectivity, non-contact and high precision. Especially in the field of industrial production, it has a strong application value in repetitive and mechanical operation. Only when the quality of the products is guaranteed for the manufacturers, can the enterprises improve the competitiveness of the products and realize long-term development.
