Aluminum parts hole detection system

First, testing requirements:




1. Detection target: aluminum parts;

2. Detection content: the size of the hole, the position of the hole, the burr of the hole;

3. Workpiece material: aluminum;

4. Size: overall dimensions of the workpiece: 230×100×40, the size of the detection part: 230×65.4, hole size: φ2.0~φ2.4, hole spacing (center distance) :18.

Second, the detection principle:




Detection objective: To measure the size of the hole on the product, where the standard aperture size is 51.85, tolerance is ±0.05. 

Detection method: Using the backlight irradiation method, the camera can get a clear outline image of the product.

Software detection principle: The diameter information of the hole can be obtained through contour recognition and circle fitting, and the detected value is compared with the standard value. If the tolerance range is exceeded, the NG (unqualified) signal is output, and if the tolerance requirements are met, the OK (qualified) signal is sent.
