Abstract

The invention discloses a test fixture for backlight glue application. The test fixture for backlight glue application includes a bearing plate, a first test fixture and a second test fixture. The bearing plate is provided with a positioning plate. There is a first positioning part for positioning the backlight source. The first inspection fixture is arranged on the carrier plate and adjacent to the first positioning part. The first inspection fixture includes a first inspection block, which can be turned over and The gluing area of ​​the backlight can be blocked, and the second inspection fixture is detachably and movably arranged on the carrier board. The second inspection fixture includes a second positioning part and a second inspection block, and the second positioning part and the second positioning part The parts cooperate to limit the freedom of movement of the backlight, and the second inspection block can be turned over and can block the glued area of ​​the backlight. The backlight glue sticking inspection jig according to the embodiment of the present invention has simple operation, good detection accuracy and strong practicability.

Description

technical field [0001] The present invention relates to the technical field of display device processing, in particular to a backlight source glue inspection jig. Background technique [0002] In the TFT-LCD industry chain, the backlight source is a very important part of the industry chain. Shading glue is one of the core components of the backlight. As end products have higher and higher requirements for appearance and thinner and thinner end products, the design of the width and thickness of the light shielding glue is getting narrower and thinner. When the product is assembled, the assembly requirements are higher, and the assembly process requirements are higher. During the assembly process, the light-shielding glue is narrow and thin, and it is difficult for personnel to control the attachment accuracy requirements when attaching the tape. The assembled light-shielding glue is easy to deviate from the attachment specification, and it is not easy to visually detect def...
