[0004] First, when the technician manually inserts the signal cable, he needs to use human eyes to accurately insert the signal cable into the connector of the PCB so that the signal of the inspection machine body can be transmitted to the screen. Due to the limited accuracy of the human eye, It will take a long time to insert the signal cable;
[0005] Second, when the technician manually pulls out the signal cable, due to the limited accuracy of manual operation, it is easy to cause damage to the PCB connector, which will cause damage to the entire TFT-LCD product

Abstract
The invention discloses a device and a method for signal cable conductor drawing-out and plugging-in in lighting inspection. When the lighting inspection is needed, a printed circuit board (PCB) of a thin film transistor-liquid crystal display (TFT-LCD) is fixed. Under the control of a controller, a signal transmission module is driven and moved to the position of a PCB connector and is connected with the PCB connector, and a signal transmission line is connected. After the lighting inspection, under the control of the controller, the signal transmission module is driven to be disconnected with the PCB connector. By adopting the method of the invention, an automatic drawing-out and plugging-in process of the signal cable conductor can be realized so as to reduce damage to the PCB connector in the lighting inspection process.
Description
technical field [0001] 本发明涉及薄膜晶体管-液晶显示(TFT-LCD,Thin Film Transistor-Liquid Crystal Display)的点灯检查技术,特别是指一种点灯检查中插拔信号电缆线的装置及方法。 Background technique [0002] TFT-LCD的生产过程中,在屏幕的外引线焊接(Panel Outer Lead Bonding)过程完成后,需要进行点灯检查,检查屏幕的品质,以确保生产出的TFT-LCD屏幕的品质完好。 [0003] 在进行点灯检查时,需要将连接检查机本体的信号电缆线插入印刷电路板(PCB,Printed Circuit Board)的连接器(Connecter),并在点灯检查完成后,将信号电缆线从PCB的连接器中拔出。目前,插拔信号电缆线的操作均采用手动方式进行。但是,手动方式存在以下缺陷: [0004] 第一,技术人员手动插入信号电缆线时,需要借助人眼将信号电缆线准确插入PCB的连接器中,以使检查机本体的信号能传输到屏幕上,由于人眼的精度有限,如此,会造成插入信号电缆线所需的时间比较长; [0005] 第二,技术人员手动拔出信号电缆线时,由于人工操作的精度有限,容易对PCB的连接器造成损伤,从而会对整个TFT-LCD产品造成损伤。 Contents of the invention [0006] 有鉴于此,本发明的主要目的在于提供一种点灯检查中插拔信号电缆线的装置及方法,能实现自动插拔信号电缆线,从而降低点灯检查过程中对PCB的连接器的损伤。 [0007] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0008] 本发明提供了一种点灯检查中插拔信号电缆线的装置,包括:PCB,PCB包括连接器,该装置还包括:固定装置、控制器、驱动装置、以及信号传输模块;其中, [0009] 固定装置,用于在需要进行点灯检查时,固定PCB; [0010] 控制器,用于控制驱动装置进行驱动; [0011] 驱动装置,用于在控制器的控制下,驱动信号传输模...
