Description

Technical Field

[0001] The utility model relates to the field of bonding of curved multi - screen displays such as vehicle - mounted industrial control, and specifically relates to a bonding jig for special - shaped curved multi - screens. Background Technique

[0002] At present, touch display screens are widely used in fields such as mobile phones, computers, vehicle - mounted central controls, industrial control displays, etc. The full - bonding technology is becoming more and more prominent, and the full - bonding of special - shaped curved multi - screens has become a difficult point. The bonding method of special - shaped curved multi - screens: using equipment for bonding and CCD equipment for positioning. It is necessary to use CCD to grab the alignment size, perform alignment compensation, and control the bonding accuracy between the multi - screen and the module. On the one hand, the single - piece bonding time is long and the efficiency is not high; on the other hand, due to the characteristics of the multi - screen, the corners are designed as rounded corners, and the equipment cannot perform positioning; on the one hand, it has high requirements for the technical ability of engineering technicians; on the other hand, it has high requirements for the equipment, that is, the capital cost is high. Now, a bonding jig for bonding liquid crystal panels or liquid crystal modules for special - shaped curved multi - screens is provided. The jig debugging is simple and has low requirements for engineering technicians; secondly, using the jig for bonding and alignment, the operation is simple, the production efficiency is high, the equipment does not require multi - axis linkage, reducing the dependence on the equipment, and the R & D difficulty and cost of the equipment are greatly reduced.

[0003] The publication number CN218383543U discloses a curved multi - screen bonding jig, which includes a bonding jig transfer board and a bonding jig upper mold. A middle bonding jig lower mold is bolted to the outer wall of the top of the bonding jig transfer board near the middle position, a stainless - steel mini cylinder one is installed on the outer wall of the top of the bonding jig transfer board near one side position, and a stainless - steel mini cylinder two is installed on the outer wall of the top of the bonding jig transfer board near the other side position.

[0004] In the above-mentioned prior art, the right fitting jig lower die, the left fitting jig lower die and the fitting jig transfer board are connected by the stainless steel mini cylinder 1 and the stainless steel mini cylinder 2. The middle fitting jig lower die and the fitting jig transfer board are fixed by bolts. When the upper die of the fitting jig presses down, the left fitting jig lower die and the right fitting jig lower die can be respectively driven by the stainless steel mini cylinder 1 and the stainless steel mini cylinder 2 to rotate through the fitting jig connection hinge, so as to realize the automatic adjustment of the pressing angle. The liquid crystal module or the liquid crystal panel limiting module positions the product to meet the relative position adjustment between multiple liquid crystal modules or liquid crystal panels. The display screen cover lifting limiting module and the display screen cover lifting adjustment block module perform the limiting and alignment adjustment of the curved multi-screen cover to meet the alignment between the curved multi-screen cover and the liquid crystal module or the liquid crystal panel. However, the above-mentioned prior art does not set a fine-tuning device, and the fitting of the curved multi-screen display is a very careful process. Without using a fine-tuning device, accidents are likely to occur during the fitting process of the curved multi-screen display. Therefore, using a fine-tuning device can make the fitting effect of the curved multi-screen display better. Summary of the Invention
