Currently, multilayer boards need to be tested for thickness after production. However, the current thickness measuring device cannot detect multiple positions of the multilayer board. In this regard, a multilayer board thickness measuring device is proposed, which can perform multi-point detection on the multilayer board and detect the surface flatness of the multilayer board at the same time.

The device comprises a frame, a hydraulic station, and a thickness measuring frame located at the bottom of the frame. The frame is equipped with a thickness measuring frame, which includes a detection pressure head, linear bearings, guide rods, a thickness gauge, a magnetic scale reader, and a cylinder. The cylinder is connected to the hydraulic station and has a detection pressure head connected to the output end. The detection pressure head is connected to one end of the guide rod, which is in motion with the linear bearing. The thickness measuring device in the aforementioned patent has the following drawbacks: It cannot measure the height of a multilayer plate at multiple locations, which affects the accuracy of the test results.
