[0002] With the rapid development of the mobile Internet industry and the rapid expansion of the market for electronic products such as mobile phones and tablets, the glass panels used to protect the display screens of electronic products are becoming more and more diverse. The demand for glass panels for various electronic display screens is increasing, and the quality control in the processing process has also attracted much attention, and defect detection is a very important link. Flatness is an important indicator that needs to be detected for mobile phone glass cover plates.

[0003] When measuring the flatness of a mobile phone glass cover, it is often necessary to use a positioning mechanism to fix the position of the cover before testing it with a micrometer. However, after the existing ordinary positioning mechanism has completed the position test of the fixed glass cover, the elastic mechanism of the positioning mechanism clamps the cover, which makes it difficult for personnel to remove the tested cover. Moreover, when measuring, the positioning mechanism that continuously provides clamping force will cause the glass cover to bend to a certain extent, thereby affecting the accuracy of the actual test of the glass cover.

[0004] Therefore, it is necessary to provide a mobile phone glass cover flatness measuring device to solve the above technical problems. Utility Model Content
