1. Definition of size inspection
Size inspection is based on the drawing to check whether the product size is within the tolerance range, in order to discover errors in shape and size. In addition, the accuracy of the machining reference plane position, the distribution of machining allowance, and wall thickness deviation can also be carefully checked
2. Size detection methods
The actual size of the product is often indispensable, but may not be provided due to the complexity of the object surface or the limitations of objective physical conditions.
. Machine vision detection technology can effectively handle such problems. In traditional automated production, the typical method of size detection is to manually use micrometers, vernier calipers, feeler gauges, and other naked eye measurements. However, such measurement methods have low measurement accuracy and slow speed, and cannot meet the needs of large-scale automated production. Machine vision based size detection is a non-contact measurement that has the advantages of high detection accuracy, fast speed, low cost, and convenient installation. It can detect various sizes of parts, such as length, height, width, circle, R-angle, multi segment height, etc3. Application scope of size detection
Electronic components, automotive parts, mobile phone parts, screws and nuts, hardware, magnetic materials, plastic, ceramics, buttons and other composite material components, magnesium, aluminum and their alloy parts can all be detected using machine vision detection technology
