Fixing device and jig for screen testing

Abstract

The invention relates to the technical field of electronic equipment testing, in particular to a fixing device for screen testing. The device comprises a product fixing part and a pulling part connected with the product fixing part. The product fixing part comprises a product fixing plate, a fixing groove is formed in the product fixing plate and used for placing a screen to be tested, and one or more clamping parts for clamping the screen to be tested are arranged in the fixing groove. The invention further provides a jig for screen testing. The jig comprises a testing frame and a testing assembly installed in the testing frame. The fixing device is further arranged in the testing frame and used for screen testing. In the testing process of the screen of an electronic product, friction and collision between the screen and the fixing groove are reduced, meanwhile, one fixing groove can be used for testing screens different in specification, and therefore production cost is reduced. Multiple fixing grooves and multiple electric conduction modules are matched for testing at the same time, so that production efficiency is improved, and the occupied space occupied in production is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment testing, in particular to a fixing device and fixture for screen testing. Background technique [0002] The test fixture belongs to a category under the fixture, and it is a kind of fixture specially used for testing and testing the function, power calibration, life, and performance of the product. Because it is mainly used for testing various indicators of products on the production line, it is called a test fixture. [0003] Functional test fixture is a kind of mechanical auxiliary equipment used to test semi-finished products / finished products or a certain process in the production process to judge whether the tested object has reached the purpose of the original designer. Functional test fixtures are used in analog, digital , memory, RF and power circuits, each form requires a corresponding functional test fixture. [0004] The screens of existing electronic devices, such as mob...

AI Technical Summary

Problems solved by technology

[0004] The screens of existing electronic devices, such as mobile phones and tablet computers, need to be tested before assembly to ensure the pass rate of the final product. When testing the screen, the screen is often powered on to observe the display status of the product. Currently, the test The process is either manual, the operation is complex and has certain risks, and the accuracy rate is low

[0005] When using semi-automated testing, the screen to be tested is usually fixed through the fixing slot on the fixing device. The size of the fixing slot is set, and only screens that match its specifications can be placed, which requires testing. Fixing devices of various specifications are set up according to different screen sizes, resulting in an increase in production costs; at the same time, even if it is an adapted fixing slot and screen, the fixing slot is often slightly larger than the size of the screen to facilitate the placement of the screen, but Because the screen and the fixed slot are in rigid contact, bumps and damages are prone to occur during the translation and pick-and-place process, which increases the loss of production
