Multi-pressure adjustable test device for biological recognition module

Abstract

The invention discloses a multi-pressure adjustable test device for a biological recognition module. The multi-pressure adjustable test device comprises a base, a left support plate, a right support plate, a horizontal bridge plate, at least one horizontal objective table and an adapter plate mounted on the horizontal objective table. Two x-direction linear rails are disposed on the surface of thebase in parallel. At least one lifting plate is located between the horizontal bridge plate and the horizontal objective table. The upper end of the lifting plate has an inverted T-shaped through hole composed of a communicating hole and a rectangular through hole which communicate with each other. At least one vertical cylinder is mounted on the upper surface of the horizontal bridge plate. A left cylinder, a right cylinder and a test pressure head seat are arranged in the cavity of a plastic cavity box. A test pressure head for detecting the electrical performance of a fingerprint module isfixed to the test pressure head seat. The test pressure head seat extends out of the plastic cavity box. A counterweight is mounted on the upper end surface of a hanging plate. The multi-pressure adjustable test device not only achieves high efficiency, but also realizes effective contact. A test has no damage to a product, and test data has high reliability and precision.

Description

technical field [0001] The invention relates to a test device, in particular to a multi-pressure adjustable test device for a biometric identification module. Background technique [0002] With the development of electronic technology, there are more and more functional and user-friendly mobile devices. For example, Apple installed a fingerprint recognition chip on the main button of Iphone5s for the first time, which brought users a convenient and fast body feeling. Since then, it has been equipped with fingerprint recognition chips. Functional mobile phones have become the basis for the public to choose mobile phones, and other brands of mobile phone manufacturers have also equipped their mobile phones with fingerprint locks. [0003] Therefore, this also brings opportunities and challenges to fingerprint module packaging companies. How to improve product performance and production efficiency is what they need to care about. In each process of fingerprint module packaging,...

[0003] Therefore, this also brings opportunities and challenges to fingerprint module packaging companies. How to improve product performance and production efficiency is what they need to care about. In each process of fingerprint module packaging, fingerprint module functional testing is very critical. Now Existing technologies are pneumatic and pressure rod pressure methods. Due to the problems of these two pressure fixtures, the force exerted by the test pressure head connected to them on the product surface is unstable, which affects the reliability of product testing. Although the above One advantage of the pressure application method is that the pressure value is adjustable, but the adjustable range is limited. For example, the pneumatic pressure application method is difficult to provide low pressure. Therefore, when improving the pressure application method in the test device, a better solution The scheme should not only take into account the improvement of test stability, but also make the pressure easy to adjust
