In product manufacturing, appearance inspection is a very important area, from a product to contact the materials, components before the final result, there may be an important initial prototype of a different appearance. Appearance size detection needs high cost, deflection detection ability and effect can be satisfied. Therefore, more and more factories begin to visual inspection equipment to replace the appearance of artificial products inspection.

It has the advantages of low detection cost, effective detection method and high efficiency. Is a common measurement technology used in the automation industry, the application of measurement industry measurement measurement, such as length, circular Angle measurement, radian measurement, etc., the following, various most commonly used measurement technology machine vision appearance size detection.

1. Definition of size detection

Size detection screen detection is to detect the size of products within the accuracy range, and size, mechanical processing volume, processing datum and precision position as a whole.

2, size detection method

The actual size of the product may not be producible, and the machine cannot be supplied due to surface detection capabilities or physical conditions. Visual technology can handle this kind of problem very well. In the traditional automation, the typical method of detection and detection is to use micrometer, stopper and other naked eyes to measure, such a measurement method can not be accurate measurement, manual acceleration, fully realize the needs of standard automation. The detection based on machine vision is a non-contact measurement, which has the advantages of high detection accuracy, fast speed, low cost and easy installation. It can detect parts of various sizes, such as long, high, wide, round and angular sections.

3. Scope of application of size detection

Electronic screws, AUTO PARTS, mobile PHONE parts, bolts, parts 50 materials, plastic ceramics, buttons and other composite materials machine materials, aluminum magnesium alloy and other alloys can be tested.

Relatively speaking, product inspection has the characteristics of particularity, non-contact and continuous visual production. Can ensure that the enterprise's product performance quality, to achieve development.
