Problems solved by technology

[0002] With the rapid development of flat panel displays and the improvement of people's living standards, liquid crystal displays are more and more widely used in people's daily life. As a common product, FOG LCD screens are widely used in the industry. After the production of FOG LCD screens is completed, it needs To inspect the product, the operator needs to manually connect the electrical part of the LCD screen to be tested. However, the success rate of the connector connection of the LCD screen and the stability after the connection have high requirements for the operator, and it is often necessary to repeat the connection many times to achieve The reliability and stability of the connection, so not only the efficiency is low, but also the success rate of pointing the screen is low

Abstract

The invention discloses an automatic crimping structure of a FOG liquid crystal screen. The automatic crimping structure comprises a base plate, a carrying tool, and a crimping device, the surface of the carrying tool is provided with a groove for containing and limiting a to-be-detected liquid crystal screen and a guiding groove for guiding and limiting a FPC of the to-be-detected liquid crystal screen, the crimping device comprises a clamping portion, a driving portion, and a signal transmission portion, the clamping portion comprises a clamping fixed part fixedly connected with the carrying tool and a clamping movable part movably connected with the clamping fixed part, the signal transmission portion comprises a signal switching probe and a signal line, the guiding groove guides the FPC of the to-be-detected liquid crystal screen to the clamping portion, the driving portion drives the clamping movable part to clamp or loosen a connector of the to-be-detected liquid crystal screen, the signal switching probe is arranged on the clamping movable part and can be connected with the connector of the to-be-detected liquid crystal screen, one end of the signal line is connected with the signal switching probe, and the other end of the signal line is electrically connected with a control terminal. According to the automatic crimping structure, automatic control is realized, the positioning is accurate, the precision is high, the liquid crystal screen can be lit at each connection, and the test efficiency and the screen-lighting success rate can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of testing liquid crystal panels, in particular to a FOG liquid crystal screen automatic crimping structure.
