The case is an important component of the watch, which is generally a frame-shaped structure, such as a circular ring or a square shape. In the process of making the case, it is necessary to test the structure of the case, such as the inner diameter of the glass assembly position of the case, the distance between the lugs, and the height of the glass assembly position.

For the detection of the case, the traditional method is to use manual detection, and workers use measuring tools (go gauge, stop gauge, height gauge) to measure manually. The measurement accuracy of the measuring tool depends on the accuracy of manual operation, and the reliability of the measurement results is weak. For example, the case is not flat during the measurement, which will cause the thickness of the case to be inaccurate. In addition, some measuring tools need to be measured by clamping the surface of the workpiece, which is easy to cause scratches on the product. For example, the height gauge needs to clamp the upper and lower end surfaces of the watch case with calipers, which is easy to scratch the end surface of the watch case. Furthermore, manual inspection is prone to work fatigue and low work efficiency.
