Embodiment Construction

[0020] See Figure 4 , Is a three-dimensional schematic diagram of the backlight module detecting device of the present invention when detecting the light guide plate. Wherein, the backlight module detection device 4 clamps and fixes a light guide plate 40. The backlight module detection device 4 includes a detection workbench 400, a flip device 480, two movable light-emitting diodes 420, a movable electrode clamp 470, and a backlight module positioning mechanism (not shown). The inspection workbench 400 includes a power source 410 located below it. The flip device 480 includes two light emitting diodes 482, a flip cover 486, two sliders 484, and a handle 483. The light emitting diodes 482 are welded to the flip cover 486, and the flip cover 486 is pivoted to the flip cover 486 through a linkage mechanism (not shown). On the two sliders 484, the handle 483 is installed on one side of the flip cover 486, so that the flip cover 486 can be flipped around the linkage mechanism by the ...

Abstract

This invention relates to one aphototropism module set test device, which comprises one test workbench, one turnover device, one movable luminescence diode, one movable electrode clamper and one positioning structure. The turnover device comprises one luminescence diode, one turnover cover and two projecting blocks, wherein the diode is welded to the cover centered on the two blocks through connection lever. The two blocks can move within certain range on the workbench.

Description

【Technical Field】 [0001] The invention relates to a detection device, in particular to a backlight module detection device. 【Background technique】 [0002] In the liquid crystal display (LCD, Liquid Crystal Display) manufacturing process, the back-end module assembly process is the production operation of assembling the glass panel after the liquid crystal is poured with other components such as light guide plates, optical sheets, circuits, and outer frames. . In the module assembly process, the light guide plate and the backlight module are usually illuminated to check whether the surface of the light guide plate is clean and whether the backlight module is properly electrically connected. [0003] figure 1 It is a top view of the prior art light guide plate cleanliness detection device 1, which clamps and fixes a light guide plate 10. The light guide plate cleanliness detection device 1 includes a detection workbench 100, two positioning blocks 150, and two light-emitting dio...
