Description

Technical Field

[0001] The utility model mainly relates to the technical field of PCB plugging, and in particular to a device for assisting a medium-sized screen in PCB plugging. Background Art

[0002] In the production process of LCD screens, it is necessary to connect the LCD panel to the drive circuit to achieve signal transmission and control. The traditional connection method is to use a connecting wire, but this method has some disadvantages, such as unreliable connection and unstable transmission. Therefore, with the development of technology, FPC plug-in PCB board has gradually become the mainstream way of connecting the drive circuit; the plug-in process makes the connection between FPC and PCB board more convenient and quick, without welding or other operations. And the stability is better, because it is a mechanical structure connection, it will not be affected by humidity and temperature; at the same time, it is easy to maintain, and the FPC and PCB board are divided into two independent components, which can be repaired separately.

[0003] However, in the current production process of medium-sized screens, the FPC and PCB are plugged in before the screen is completed, so the screen must not be damaged during the plug-in process. Also, due to the special mechanical structure of the plug-in locking part of the FPC and PCB board, it is very awkward for workers to perform the plug-in process, which is inconvenient to operate and has low production efficiency.
