Backlight semi-finished product assembling jig

Abstract

The invention provides a backlight semi-finished product assembling jig, which comprises a jig base, the jig base is divided into a working table area and a detection area, a positioning assembly used for positioning a backlight semi-finished product workpiece is arranged in the working table area and comprises sliding grooves formed in the jig base, and a sliding base used for positioning the side face of the workpiece is arranged in the sliding grooves in a matched mode; a detection assembly is arranged in the detection area and comprises a backlight source electric connection base electrically connected with the workpiece and at least one detection lamp electrically connected with a power source and used for detecting foreign matter in the workpiece. Compared with the prior art, the backlight semi-finished product assembling jig has the advantages that the upper, lower, left and right sliding grooves and matched sliding blocks are formed in the working table area, backlight source display screen semi-finished product workpieces of different sizes can be adapted, in the assembling process, illumination detection is conducted in real time through electrical connection of the backlight source electric connection base and a semi-finished product, the product yield is increased, and the productivity loss is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight semi-finished product assembly jig. Background technique [0002] Such as figure 1 As shown, the backlight display generally includes a FOG liquid crystal display 1, a backlight film material 2, a plastic frame 3, a light guide plate 4, a reflective sheet 5, and a metal back plate 6. The backlight film material 2 includes a lower diffusion sheet 21, The lower brightness enhancement sheet 22, the upper brightness enhancement sheet 23 and the word glue 24, the light guide plate 4 is located on the back of the lower diffusion sheet 21, and the light inlet of the light guide plate 4 is provided with a light bar LB41, which are assembled layer by layer during assembly. However, since the size of the backlight display screens varies greatly, fixtures of different sizes need to be equipped to adapt to different sizes of display screens during assembly, which wastes res...

Problems solved by technology

However, since the size of the backlight display screens varies greatly, fixtures of different sizes need to be equipped to adapt to different sizes of display screens during assembly, which wastes resources; The limit of the position cannot be exactly the same, and it cannot be detected in real time during the assembly process, resulting in a low assembly yield and increased production and energy consumption
