A double-turning indenter for display panel inspection and a display panel inspection fixture

Abstract

The invention discloses a double-turning indenter for display panel testing and a display panel testing fixture, which include a first turning component, a second turning component and a TP-FPC positioning component are arranged on the first turning component, the The flipping hinge on the first flipping assembly and the flipping hinge on the second flipping assembly are arranged perpendicular to each other, the second flipping assembly is provided with a TP-FPC conduction pressure head, and the TP-FPC positioning assembly is set A TP-FPC positioning groove is arranged on the top, and the position of the TP-FPC conduction pressure head corresponds to the position of the TP-FPC positioning groove. The present invention can effectively avoid the interference between the main FPC and the conduction pressure head when the display panel is installed, and it is convenient and quick to conduct on the display panel with the main FPC and TP-FPC bound at the same time and the projection of the main FPC and TP-FPC overlapping. TP‑FPC, to achieve rapid detection of TP‑FPC parts.

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
