OLED screen pneumatic pressing needle device

Abstract

An OLED screen pneumatic pressing needle device comprises a horizontally arranged loading base plate, a vertically arranged guide rail mounting plate and a horizontally arranged lifting cross plate, wherein the guide rail mounting plate is fixedly connected on one side of the loading base plate, the lifting cross plate and the guide rail mounting plate are in sliding connection, the loading base plate is provided with a lifting device for raising and lowering the lifting cross plate, and a buffer device is arranged on the guide rail mounting plate; the lifting cross plate is provide with a pressing needle device, a screen to be tested is correspondingly placed under the pressing needle device, and the pressing needle device moves up and down with the lifting cross plate to make contact or separation between the pressing needle device and a screen electrode to be , thereby lighting on or off the screen to be tested. The beneficial effects of the present invention are as follows: the guide rail and the lifting device are used to achieve consistent trajectory of the pressing needle at each lowering, uniform force, enough brightness during the lighting process of the screen, thereby avoiding the occurrence of a failed point and the like and achieving automatic operation.

Description

technical field [0001] The invention relates to an OLED screen device, in particular to a pneumatic needle pressing device for an OLED screen. Background technique [0002] At present, OLED screens have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, wide operating temperature range, and relatively simple structure and manufacturing process. It is considered to be the next-generation flat-panel display emerging application technology. In the production process of OLED screens, the quality of LCD screens needs to be monitored in real time just like LCD screens. During the test process, OLED screens need to be lighted up with pressing pins for detection. Both lead to insufficient brightness during the lighting process of the screen, and the occurrence of situations such as the point not being bright, so it is necessary to develop a new type of OLED screen press...

In the production process of OLED screens, the quality of LCD screens needs to be monitored in real time just like that of LCD screens. During the testing process, OLED screens need to be lighted up with pressing pins for detection. Both lead to insufficient brightness and failure to light up the screen during the lighting process, so it is necessary to develop a new type of OLED screen pressing device
