Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0045] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0046]In addition, if there are descriptions involving "first", "second" and s...

The invention discloses an assembly fixture and an assembly process for a liquid crystal panel and a display backplane. The assembly process for the liquid crystal panel and the display backplane includes the following steps in sequence: Step S10, clamping and positioning the display backplane by the inner sides of two limiting structures , and the liquid crystal panel is suspended above the display backplane by the suspension mechanism, and the degree of bending of the liquid crystal panel towards the display panel is adjusted by the suspension mechanism, until the two ends of the liquid crystal panel in the first direction respectively press against a limit structure Inside; process S20, the suspension mechanism lowers the liquid crystal panel toward the display backplane until the lowest point of the liquid crystal panel abuts the display backplane; Limiting the position at the end, the liquid crystal panel stretches from the lowest point to both sides along the first direction, sticks down, and sticks to the display backplane as a whole. The technical scheme of the invention can improve the anti-interference performance of the assembly alignment of the liquid crystal panel and the display back panel.
Description
technical field [0001] The invention relates to the field of display devices, in particular to an assembly jig and an assembly process for a liquid crystal panel and a display backplane. Background technique [0002] A display device generally includes a liquid crystal panel and a display backplane. The center plane of the liquid crystal panel and the center plane of the display backplane need to be aligned and installed, and they need to overlap after installation to achieve a high display quality. That is to say, the liquid crystal panel and the display The backplane is left-right symmetrical about the same center line, which can make the display quality have better centering. [0003] The existing assembly method is to use the vision system to shoot the relative position of the edge of the LCD panel and the display backplane to calculate and correct the gap between the edge of the LCD panel and the edge of the display backplane, so as to realize the accuracy during the as...
