Description

Technical Field

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

[0002] Currently, touch screens are widely used in mobile phones, computers, vehicle-mounted central control, industrial control displays and other fields. Full-lamination technology is becoming more and more prominent; among them, the full lamination of special-shaped multi-screen display panels has become a difficult point. The lamination method of special-shaped multi-screen display panels: using equipment for lamination and CCD equipment for positioning. It is necessary to use CCD to capture the alignment size and perform alignment compensation. The lamination accuracy between the control panel and the LCD panel, on the one hand, the single-piece lamination time is long and the efficiency is not high. On the other hand, it requires high technical capabilities of engineering and technical personnel. On the other hand, it requires high equipment requirements, that is, high capital costs. A lamination jig is now provided for laminating special-shaped multi-screen display panels to LCD panels. The jig is simple to debug and does not require high requirements for engineering and technical personnel. Secondly, the jig is used for lamination and alignment, which is simple to operate and has high production efficiency. The equipment does not require multi-axis linkage, which reduces dependence on the equipment, and the equipment R&D difficulty and cost are greatly reduced.

[0003] Publication number CN2023117235484 discloses a jig for laminating a special-shaped curved display panel, including a lower template, a lower template base plate, an upper template and an upper loading plate, wherein the lower template is located directly above the lower template base plate, a vacuum groove is provided on the lower template base plate, an exhaust hole is provided inside the vacuum groove, a vacuum hole is provided at the position of the lower template facing the vacuum groove, the upper template is located directly below the upper loading plate, and the upper template and the upper loading plate are movably connected through a linear bearing assembly, wherein a through groove is provided on the upper loading plate, and a positioning groove is provided on the upper template.

[0004] After the initial curing of the glue for fixture bonding, it still takes some time for the glue to be fully cured. Different glues have different full curing times. For example, UV glue requires 1-2 hours to fully cure; thermal curing glue requires initial curing within 5-30 minutes, but requires several hours to 24 hours to fully cure; two-component glue requires initial curing within 1-2 hours, but may require 24 hours to fully cure. Therefore, for glues with longer full curing times, it is necessary to maintain pressure to help improve the final bonding strength. However, the above-mentioned prior art only uses positioning components to directly clamp and position the display panel to achieve fixture bonding and alignment, and cannot achieve continuous fixture bonding, so it is difficult to improve the bonding strength. The use of an automated bonding machine to apply continuous pressure will affect the efficiency of fixture bonding, which can easily lead to low efficiency. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figures 1 to 6 , the utility model provides a technical solution:

[0028] A special-shaped multi-screen display panel lamination jig includes a base plate 1, a panel support plate 2, a linear bearing 3, a non-return assembly 4, a return spring 5, a liquid crystal support assembly 6 and a fixing assembly 7. The panel support plate 2 is set on the base plate 1 through the linear bearing 3, wherein:

[0029] A check assembly 4 and a return spring 5 are provided between the base plate 1 and the panel support plate 2. A liquid crystal support assembly 6 is provided on the base plate 1 and within the panel support plate 2. A fixing assembly 7 is provided on the panel support plate 2 to secure the display panel. The check assembly 4 prevents the panel support plate 2 from rebounding, thereby maintaining the contact between the special-shaped multi-screen panel and the liquid crystal panel.

[0030] As a preferred embodiment, the check assembly 4 includes a connecting rod 41, a switch sleeve 42, a movable block 43, a spring I 44, and a hook rod 45. The connecting rod 41 is connected to the panel support plate 2, and the switch sleeve 42 is rotatably mounted on its other end. The movable block 43 is laterally movable and mounted within the switch sleeve 42. One end of the movable block 43 is connected to the switch sleeve 42 via a spring I 44, and the other end is a beveled switch portion. The beveled end of the movable block 43 facilitates movement of the switch sleeve 42 toward the hook rod 45. The hook rod 45 has one end mounted on the base plate 1 and the other end is a locking portion. The locking portion comprises two stop plates disposed on either side of the outer circumference of the hook rod 45, with a clearance slot between the two stop plates for the movable block 43 to pass through. When the movable block 43 is not in contact with the hook rod 45, the spring I 44 is relaxed. When the panel support plate 2 is pressed downward, the panel support plate 2 drives the switch sleeve 42 toward the hook rod 45 via the connecting rod 41. At this time, the inclined switch portion of the movable block 43 contacts the stop plate of the hook rod 45. Under the pressure between the inclined switch portion and the stop plate, the movable block 43 moves to both sides, which gradually compresses the spring I 44. When the upper end of the inclined switch portion of the movable block 43 contacts the lower end of the stop plate, the compressed spring I 44 is released, and the movable block 43 is stuck at the lower end of the stop plate, completing the non-return action. When the non-return action needs to be released, the switch sleeve 42 is rotated, and the switch sleeve 42 simultaneously drives the movable block 43 to rotate, so that the movable block 43 is located in the gap groove of the stop plate. At this time, under the action of the return spring 5, the panel support plate 2 returns to its original initial position.

[0031] As a preferred embodiment, the liquid crystal support assembly 6 includes a liquid level support box 61 and a vacuum pump 62 . The liquid level support box 61 is arranged on the bottom plate 1 and located inside the panel support plate 2 . The vacuum pump 62 is connected to the liquid level support box 61 .

[0032] As a preferred embodiment, the fixing assembly 7 includes a fixed stop block 71, a movable stop block assembly I 72 and a movable stop block assembly II 73. A fixed stop block 71 is provided at one end of the panel support plate 2 and a movable stop block assembly I 72 is provided at the other end. A fixed stop block 71 is provided on one side of the panel support plate 2 and a movable stop block assembly II 73 is provided on the other side.

[0033] As a preferred embodiment, the movable stopper assembly I 72 includes a fixed block 721, a spring II 722, and a pull rod I 723. The fixed block 721 is movably arranged in the panel support plate 2. One end of the spring II 722 is connected to the fixed block 721 and the other end is connected to the panel support plate 2. The pull rod I 723 is movably arranged on the panel support plate 2 and connected to the fixed block 721. When the special-shaped multi-screen display panel is placed on the panel support plate 2, the fixed block 721 will compress the spring II 722. The restoring force of the spring II 722 is used to fix the special-shaped multi-screen display panel. When the special-shaped multi-screen display panel needs to be unfixed, it is only necessary to pull the pull rod I 723 to increase the gap between the fixed block 721 and the special-shaped multi-screen display panel to release the fixation.

[0034] As a preferred embodiment, the movable stopper assembly II 73 includes a movable stopper 731, a spring III 732, and a pull rod II 733. The movable stopper 731 is movably arranged on one side of the panel support plate 2. One end of the spring III 732 is connected to the movable stopper 731 and the other end is in contact with the panel support plate 2. The pull rod II 733 is arranged on the movable stopper 731. When the special-shaped multi-screen display panel is placed on the panel support plate 2, the movable stopper 731 will compress the spring III 732. The elastic force of the spring III 732 is used to fix the special-shaped multi-screen display panel. When the special-shaped multi-screen display panel needs to be removed, it is only necessary to pull the pull rod II 733 to increase the gap between the movable stopper 731 and the special-shaped multi-screen display panel to release the fixation.

[0035] As a preferred embodiment, the upper surface of the liquid level support box 61 is uniformly arrayed with vacuum holes 611, and the side of the liquid level support box 61 is provided with air inlet holes 612. The vacuum holes 611 facilitate the vacuum pump 62 to evacuate the air between the liquid crystal panel and the liquid level support box 61, thereby achieving vacuum adsorption and securing the liquid crystal panel. The air inlet holes 612 facilitate the injection of outside air between the liquid crystal panel and the liquid level support box 61, thereby releasing the vacuum adsorption.

[0036] As a preferred embodiment, the heights of the fixed block 71, the fixed block 721, and the movable block 731 are all higher than the height of the liquid level support box 61 after the liquid crystal panel is adsorbed. The heights of the fixed block 71, the fixed block 721, and the movable block 731 are the same as the height of the special-shaped multi-screen display panel placed on the panel support plate 2.

[0037] The working principle of this utility model:
