Fingerprint module station height measuring mechanism and station height measuring method

Abstract

The invention aims to provide a fingerprint module station height measuring mechanism and a station height measuring method; the fingerprint module station height measuring mechanism comprises a support with a crossbeam, a mobile linear guiderail arranged on top of the crossbeam, a mobile seat connected with a slide block of the mobile linear guiderail, a mobile drive device, two lift assemblies matched with two side ends of the mobile seat one by one, a station height measuring device arranged on a mount base below the lift assemblies, and a lift; the lift assembly comprises a substrate connected with the side end of the mobile seat, and a lift plate connected with the substrate in a slide manner via the vertical linear guiderail; a float assembly is arranged between the bottom of the lift plate and the mount base. The float assembly is arranged between the bottom of the lift plate and the mount base of the fingerprint module station height measuring mechanism, and can float in X, Y and Z directions in 6 degrees of freedom, thus reducing lifting driving impact without forming a lateral force; the fingerprint module station height measuring precision is high.

Description

technical field [0001] The invention relates to the field of fingerprint module testing, in particular to a fingerprint module standing height measuring mechanism and a standing height measuring method. Background technique [0002] It is very important to test and classify the stand height of the fingerprint module, and to spray codes and marks according to different stand height categories, which is very important to improve the assembly quality of the mobile phone; the traditional stand height test equipment of the fingerprint module has problems due to line rail positioning and mechanical The machining error of the parts, the rigid connection of the lifting drive device has a large impact force and is easy to generate lateral force, resulting in the lack of high test accuracy of the fingerprint module station; therefore, it is necessary to design a lifting drive with a small impact force and no lateral force The fingerprint module stand height measurement mechanism and t...

[0002] It is very important to test and classify the stand height of the fingerprint module, and to spray codes and marks according to different stand height categories, which is very important to improve the assembly quality of the mobile phone; the traditional stand height test equipment of the fingerprint module has problems due to line rail positioning and mechanical The machining error of the parts, the rigid connection of the lifting drive device has a large impact force and is easy to generate lateral force, resulting in the lack of high test accuracy of the fingerprint module station; therefore, it is necessary to design a lifting drive with a small impact force and no lateral force The fingerprint module stand height measurement mechanism and the stand height measurement method with high test accuracy have become an urgent problem to be solved.

[0003] The purpose of the present invention is to overcome the current stand height test equipment for fingerprint modules, which has relatively large impact force due to line rail positioning and machining errors of mechanical parts, rigid connection of lifting drive device and easy to generate lateral force, resulting in fingerprint module stand height. Insufficient of high test accuracy and low, provide a fingerprint module stand height measurement mechanism and stand height measurement method with small lift drive impact force and no lateral force, high fingerprint module stand height test accuracy
