[0002] 3D flatness detection refers to detecting the flatness of parts by using a three-dimensional vision system. This detection method can achieve high-precision measurement of the surface of parts, and can accurately detect the flatness and parallelism of the surface of parts. Through 3D flatness detection, the machining accuracy and assembly quality of parts can be effectively improved, thereby improving the performance and reliability of the entire product.

For this reason, the utility model proposes a workpiece fixing mechanism for a 3D flatness detection device to solve the above problems. Content of the Utility Model
