Portable electronic screen turnover test fixture

Abstract

The invention discloses a portable electronic screen turnover test fixture. The test fixture comprises a platform, a control box, a PG testing box, a carrier and a PCB are arranged on the platform, and the control box is electrically connected with the PG testing box; the PG testing box is electrically connected with the PCB, the carrier is hinged with the platform through a first hinged chain, and an observing hole used for people to observe a to-be-tested electronic screen is formed in one side surface of the carrier; a locating mechanism used for accommodating and fixing the to-be-tested electronic screen is arranged on the other side surface of the carrier, the to-be-tested electronic screen is placed in the locating mechanism, and the front surface of the to-be-tested electronic screen faces towards the observing hole; an FPC is arranged between the back surface of the to-be-tested electronic screen and the PCB, one end of the FPC is electrically connected with the PCB, and the other end of the FPC is electrically connected with the back surface of the to-be-tested electronic screen. The test fixture is simple in structure, convenient to use and easy to carry and reasonably utilizes the space of the platform; through the double-layer structural design of the test fixture platform, the occupied area of the whole test fixture is effectively reduced, and operators can conveniently carry the test fixture when going out.

Description

technical field [0001] The invention relates to an electronic screen flip test fixture, which belongs to the technical field of electronic screen test fixtures, in particular to a portable electronic screen flip test fixture for FPC on the back of the electronic screen. Background technique [0002] With the rapid development of flat panel displays and the continuous improvement of people's living standards, liquid crystal electronic screens are widely used in the industry as a common product. Usually, after the production of LCD electronic screen is completed, the product needs to be inspected. The detection method is generally that the operator manually connects the electrical part of the LCD electronic screen to be tested, and then uses the PG test box to perform a lighting test on the LCD electronic screen. As a result, many electronic screen lighting test fixtures for FPC connectors located on the front of the liquid crystal electronic screen have been diffracted. Alth...

AI Technical Summary

Problems solved by technology

Although this test fixture can effectively complete the performance test of the liquid crystal electronic screen, the carrier used to carry the liquid crystal electronic screen is generally directly fixed on the workbench of the test fixture and cannot be moved and turned over. As far as the electronic screen on the back of the screen is concerned, it is necessary to manually flip the LCD electronic screen to connect to the FPC for each test, and then put the connected FPC LCD electronic screen into the vehicle for lighting test. Both the liquid crystal electronic screen and the FPC are in a state that can be moved arbitrarily, so the operation efficiency is low and the connection between the FPC and the liquid crystal electronic screen is easy to loosen, which will cause inaccurate lighting tests and damage to the electronic screen; Test fixtures are generally bulky, which is not conducive to carrying them out
