Problems solved by technology

[0003] Therefore, in the production process of the backlight module, it is necessary to carry out defect detection on the backlight module, including screen inspection, but in the screen inspection, there are often problems due to the diffuser, filter, polarizer, reflector and other components in the backlight module. The lack of flatness between the joints leads to errors in the inspection, and the effective inspection effect cannot be achieved

Abstract

The invention provides a pressure apparatus for assisting a backlight module picture checking fixture. The pressure apparatus comprises an air cover, wherein the air cover comprises a storage board, a connector fixing block connected with the storage board and a transparent board capable of being embedded onto the connector fixing board, a side edge of the storage board is provided with an adjusting check block, a side edge of the connector fixing block is provided with an air pipe connector, and the pressure apparatus also comprises a movable structure connected with a connector fixing frame and capable of adjusting the air cover. According to the pressure apparatus, the stable air pressure in the air cover is realized by virtue of inflation and deflation between the air pipe connector and the adjusting check block on the air cover, and an upper surface of a backlight module is pressed, so that backlight module components are kept flatly laminated; for a backlight module of a different model numbers and a corresponding checking fixture, the air cover can be adjusted by the movable structure to move in a front-rear direction and a left-right direction, so that the air cover can be better matched with the checking fixture; and the pressure apparatus has the advantages of simple structure, low production cost, high practicability and high automation degree.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a pressure device for assisting a backlight module inspection jig. Background technique [0002] Currently used electronic products with display functions, such as TVs, monitors, digital cameras, mobile phones, PDAs, portable DVDs, etc., display audio and video signals through liquid crystal panel configurations, and the image display of the liquid crystal panel is more dependent on the backlight mode. The light source design and quality management of the group, the backlight module will directly affect the display image effect and the picture contrast quality, therefore, a good backlight module will improve the image display quality of the LCD panel. [0003] Therefore, in the production process of the backlight module, it is necessary to carry out defect detection on the backlight module, including screen inspection, but during the screen inspection, there are often p...
