Press-connecting carrier for automatically turning testing jig

Abstract

The invention discloses a press-connecting carrier for automatically turning a testing jig. The press-connecting carrier comprises a bottom plate, a carrier body and a conduction device. A limiting and fixing structure for containing and limiting a to-be-tested liquid crystal screen is arranged on the carrier body. The carrier body is fixedly connected to the surface of one side of the bottom plate. The conduction device is fixedly connected to the surface of the other side of the bottom plate. The bottom plate and the carrier are each provided with a through hole for a FPC of the back side ofthe to-be-tested electronic screen to penetrate through. A movable stop piece for preventing the to-be-tested electronic screen from being disengaged from the carrier body is arranged beside the carrier body. The press-connecting carrier is simple in structure and convenient to use; by forming the through holes for the FPC of the back side of the to-be-tested electronic screen to penetrate through in the bottom plate and the carrier body respectively, the to-be-tested electronic screen is prevented from being manually turned.

Description

technical field [0001] The invention relates to a carrier used on a test fixture, which belongs to the technical field of testing non-standard products such as electronic screens, and in particular to a crimping carrier used on an automatic flip test fixture. Background technique [0002] With the rapid development of tablets and mobile phones and the improvement of people's living standards, various electronic devices are more and more widely used in people's daily life. However, in the production, each step needs to test the semi-finished equipment, and each mobile phone , flat panel and other screen displays are of different sizes, so the test for this needs the assistance of corresponding equipment. This equipment is mainly for some FPC products behind the electronic screen. Traditional fixtures need to be turned manually by personnel, which is inefficient and causes great damage to the electronic screen. Therefore, in order to more efficiently detect the electronic scr...

Problems solved by technology

This equipment is mainly for some FPC products behind the electronic screen. Traditional fixtures need to be turned manually by personnel, which is inefficient and causes great damage to the electronic screen.

Therefore, in order to more efficiently detect the electronic screen on the back of the FPC, a test fixture that can be turned over automatically is needed, which is easy to operate and improves the test efficiency and success rate. Therefore, the automatic turnover test fixture is used to accommodate the load to be tested The carrier of the LCD screen needs to be designed separately, because the traditional carrier does not need to be flipped, so there is no conduction device used to ensure that the FPC and the POGO connector are always in contact. For example, a FOG liquid crystal is disclosed in the Chinese invention patent CN106940976A Screen automatic crimping structure, including base plate, carrier and crimping device; the carrier surface is provided with a groove for accommodating and limiting the liquid crystal screen to be tested and a guide groove for guiding and restricting the FPC of the liquid crystal screen to be tested; the crimping device includes a clamping part , a driving part and a signal transmission part; the clamping part includes a clamping fixed part fixedly connected with the carrier and a clamping movable part movably connected with the clamping fixed part; the signal transmission part includes a signal transfer probe and a signal line; the guide The groove guides the FPC of the LCD screen to be tested to the clamping part, and the driving part drives the clamping movable part to clamp or loosen the connector of the LCD screen to be tested; the signal transfer probe is arranged on the clamping movable part and can be connected with the clamping movable part. To test the connector connection of the LCD screen, one end of the signal line is connected to the signal transfer probe, and the other end is electrically connected to the control terminal

If the technical solution of this invention is directly used on the automatic flip test fixture, when the automatic flip test fixture is turned over, there may be situations where the FPC is detached from the POGO connector and the test is inaccurate
