Multifunctional jig for key and connector detection in smart phone

Abstract

The invention discloses a multifunctional jig for key and connector detection in a smart phone. The upper surface of a box is equipped with two first guide rails and two second guide rails in parallel; a first hollow groove is arranged between the two first guide rails located at the left side; a second hollow groove is arranged between the two second guide rails located at the right side; one of two electrical testing mechanisms is in sliding connection with the two first guide rails through two first sliders located at the bottom, and the other electrical testing mechanism in the two electrical testing mechanisms is in sliding connection with the two second guide rails through two second sliders at the bottom; carrier platforms in the electrical testing mechanisms are positioned on an adapter plate by bolts; each of the electrical testing mechanisms further comprises a support plate, a cover plate and a substrate; the front end of the cover plate is moveably connected with a clamping base on the substrate through a connecting pin; and the carrier platforms are mounted on the substrates. The multifunctional jig for the key and connector detection in the smart phone provided by the invention improves the capacity and saves the manpower on the premise of ensuring high reliability, and can make corresponding movement according to the category and size of fingerprint chips, and adjust the relative positions of the electrical testing mechanisms and a lifting plate.

Description

technical field [0001] The invention relates to a device testing device, in particular to a multifunctional fixture used for testing keys and connectors in smart phones. Background technique [0002] Fingerprints refer to the uneven lines on the skin on the front of the fingertips. Although fingerprints are only a small part of human skin, they contain a lot of information. These lines are different in patterns, breakpoints and intersections. They are called "features" in Chinese, and it has been proved medically that these features are different for each finger, and these features are unique and permanent, so we can match a person with his fingerprints, and by comparing His fingerprints and pre-saved fingerprints can verify his true identity. Therefore, the fingerprint lock came into being. The fingerprint lock is an intelligent lock, which is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware te...

Problems solved by technology

[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
