Double-turnover pressure head for display panel detection and display panel detection jig

Abstract

The invention discloses a double-turnover pressure head for display panel detection and a display panel detection jig. The double-turnover pressure head comprises a first overturning assembly, whereinthe first overturning assembly is provided with a second overturning assembly and a TP-FPC positioning assembly, an overturning hinge shaft on the first overturning assembly is perpendicular to an overturning hinge shaft on the second overturning assembly, the second overturning assembly is provided with a TP-FPC conduction pressure head, the TP-FPC positioning assembly is provided with a TP-FPCpositioning groove, and the TP-FPC conduction pressure head corresponds to the TP-FPC positioning groove in position. According to the invention, the interference between the main FPC and the conduction pressure head during the loading of a display panel can be effectively avoided; the TP-FPC on the display panel bound with the main FPC and the TP-FPC at the same time can be conveniently and rapidly conducted, wherein the projections of the main FPC and the TP-FPC are overlapped; and the rapid detection of the TP-FPC part can be realized.

Description

technical field [0001] The invention relates to the field of optical detection of display panels, and relates to a double-turning indenter for display panel detection and a display panel detection jig. Background technique [0002] With the continuous development of science and technology, electronic devices such as computers, mobile phones, and tablets have been widely used in various industries. The rapid development of the above-mentioned devices is inseparable from the support of the display panel. At present, in the field of display panel manufacturing, after the panel is manufactured and before it is put into assembly, it is necessary to conduct a point-screen test on the display panel. This test is the key to ensuring the quality of the display panel. In the prior art, a display panel generally consists of the following three parts: a screen body, a main FPC, and a TP-FPC (Touch Panel-FPC). According to different devices, the display panel will bind the main FPC and ...

Problems solved by technology

In the detection stage of the display panel, the conventional crimping module generally uses a fixed one-way flipping indenter to cooperate with the FPC positioning component to achieve conduction (the structure introduction of the conventional point screen crimping module: X direction flipping, or Y direction flipping, only one direction flip, the entire crimp assembly is locked on the fixture base plate), as attached figure 1 As shown, the main FPC of the display panel is crimped and conducted through the conventional crimping module, and then the panel is detected by switching the FPC to the PCBA. The above technical solution can effectively solve the above three types of products, but when it is used for the first When testing four-form panels, since the projection directions of the TP-FPC and the main FPC overlap, when it is necessary to test the TP-FPC, the conventional crimping module is fixed, so the display panel will be in contact with the main FPC when testing the upper part. FPC interferes, so the panel conduction detection pressure head fixedly installed in the prior art cannot realize the detection of the fourth form display panel
