Specific embodiments

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] In the description of the present utility model, it should be noted that the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] As Figures 1 to 4 shown, an assembly device for liquid crystal display processing provided by the present utility model includes: a base 1, and a movable mounting plate 2 disposed on the upper side of the base. It further includes: a display fixing device 3 horizontally disposed on the upper side of the mounting plate 2. The display fixing device 3 includes a plurality of clamping mechanisms 4 vertically disposed on the mounting plate 2 and arranged in a rectangular shape, and a moving rail assembly 5 passing through adjacent clamping mechanisms 4 and fixed to the mounting plate 2. The clamping mechanisms 4 slide back and forth and left and right on the moving rail assembly 5.

[0025] The working principle and beneficial effects of the above solution are as follows:

[0026] During assembly, the liquid crystal display is placed on the clamping mechanism, and the clamping mechanism 4 is moved to a size suitable for the liquid crystal display through the moving rail assembly 5, and the liquid crystal display is clamped, so as to perform assembly.

[0027] In order to enable the clamping mechanism to be adjusted and clamped according to the size of the liquid crystal display, a preferred embodiment of the present utility model is that the clamping mechanism 4 includes a first fixed seat 4-1, a first moving seat 4-2, a second moving seat 4-3, and a third moving seat 4-4 that are vertically disposed on the mounting plate 2 and arranged in a rectangular shape, and one or more clamping members 6 respectively disposed on the first moving seat 4-2, the second moving seat 4-3, and the third moving seat 4-4. The first fixed seat 4-1 is disposed on the mounting plate 2, and the first moving seat 4-2, the second moving seat 4-3, and the third moving seat 4-4 slide on the mounting plate 2 through the moving rail assembly 5.

[0028] In order to enable the clamping mechanism to be adjusted and clamped according to the size of the liquid crystal display screen, a preferred embodiment of the present utility model is that the moving rail assembly 5 includes a first moving rail 5-1 and a second moving rail 5-2 provided on two adjacent inner sides of the first fixed seat 4-1. One end of the first moving rail 5-1 and the second moving rail 5-2 is provided on the first fixed seat 4-1. The other end of the first moving rail 5-1 passes through the third moving seat 4-4 and is fixedly installed on the mounting plate 2 through a mounting seat. The other end of the second moving rail 5-2 passes through the first moving seat 4-2 and is fixedly installed on the mounting plate 2 through a mounting seat. A third moving rail 5-3 and a fourth moving rail 5-4 are respectively provided between the first moving seat 4-2 and the second moving seat 4-3, and between the second moving seat 4-3 and the third moving seat 4-4. The third moving rail 5-3 and the fourth moving rail 5-4 are arranged in a staggered manner. The third moving rail 5-3 and the fourth moving rail 5-4 are arranged in a staggered manner and are not on the same horizontal line, so that the second moving seat 4-3 can slide synchronously on the third moving rail 5-3 and the fourth moving rail 5-4 respectively. The first moving seat 4-2 and the second moving seat 4-3 can slide synchronously on the second moving rail 5-2 and the fourth moving rail 5-4 under the action of an external force. The second moving seat 4-3 and the third moving seat 4-4 can slide synchronously on the first moving rail 5-1 and the third moving rail 5-3.

[0029] In order to better fix the liquid crystal display screen, a preferred embodiment of the present utility model is that a plurality of first racks 5-5 are provided on the upper side of one end of the mounting plate 2, and a first gear 5-6 fixedly provided at one end of the third moving rail 5-3 and the fourth moving rail 5-4 and meshing with the first rack 5-5. A hand crank 5-7 is provided on the side wall of the first gear 5-6.

[0030] In order to better fix the liquid crystal display screen, a preferred embodiment of the present utility model is that a retaining edge 7 is provided on the sides of the first fixed seat 4-1, the first moving seat 4-2, the second moving seat 4-3, and the third moving seat 4-4. The area between the retaining edges 7 is the placement area for the liquid crystal display screen.

[0031] The working principle and beneficial effects of the above solution are as follows:

[0032] During assembly, the liquid crystal display screen is placed on the fixed seat and the moving seat, and by rotating the hand crank, the first gear is driven to rotate, so that the first gear moves on the first rack, thereby driving the fixed seat and the moving seat to move left and right and back and forth on the moving rails until the clamping member contacts the liquid crystal display screen and clamps it.

[0033] In order to enable the clamping mechanism to be adjusted and clamped according to the size of the liquid crystal display screen, a preferred embodiment of the present utility model is that each of the clamping members 6 includes a limiting rod 6-1 passing through the side wall of the edge stop 7 and extending to the inside. A limiting block is provided at one end of the limiting rod 6-1 away from the liquid crystal display screen 8, and a connecting plate 6-2 is provided at one end close to the liquid crystal display screen 8. A first spring 6-3 is provided at one end of the connecting plate 6-2 away from the limiting block. A clamping block 6-4 is provided at one end of the first spring 6-3 away from the limiting block. A rubber pad is provided at one end of the clamping block 6-4 away from the first spring 6-3. External threads are provided on the outer side of the limiting rod 6-1, and internal threads adapted to the limiting rod 6-1 are provided at the corresponding positions of the edge stop 7.

[0034] The working principle and beneficial effects of the above solution are as follows:

[0035] During assembly, place the liquid crystal display screen on the fixed seat and the moving seat, and rotate the hand crank to drive the first gear to rotate, so that the first gear moves on the first rack, thereby driving the fixed seat and the moving seat to move left and right and back and forth on the moving track until the clamping member contacts the liquid crystal display screen and clamps it; after the liquid crystal display screen is placed in place, then rotate the limiting rod 6-1, and the limiting rod moves in the direction of the liquid crystal display screen. The movement of the limiting rod drives the connecting plate, the first spring, and the clamping block to move in the direction of the liquid crystal display screen. The first spring can not only make the clamping block better contact with the liquid crystal display screen, but also prevent the clamping block from damaging the liquid crystal display screen when the external force is too large.

[0036] In order to avoid damaging the liquid crystal display screen under the action of external force during the assembly process, a preferred embodiment of the present utility model is that the assembly device for processing the liquid crystal display screen further includes a buffer device 9 provided between the mounting plate 2 and the base 1. The buffer device includes a plurality of vertically arranged telescopic rods and a second spring sleeved outside the telescopic rods.

[0037] In order to avoid damaging the liquid crystal display screen under the action of external force during the assembly process, a preferred embodiment of the present utility model is that a sliding groove 10-1 is provided on the upper surface of the base 1, and a rotatable rotating shaft 10-2 is provided on one end surface of the base 1 close to the sliding groove 10-1. A second gear 10-3 is sleeved outside one end of the rotating shaft 10-2 away from the base 1. A rack shaft 10-4 which is slidably arranged in the sliding groove 10-1 and meshes with the second gear 10-3 is provided in the sliding groove 10-1. A third spring 10-5 is sleeved outside one end of the rack shaft 10-4 away from the mounting plate 2. One end of the third spring 10-5 is fixedly arranged on the side wall of the base 1. One end of the rack shaft 10-4 close to the mounting plate 2 is hinged to the mounting plate 2.

[0038] The working principle and beneficial effects of the above solution are as follows:

[0039] During assembly, the mounting plate 2 presses against the rack shaft 10-4. The rack shaft 10-4 drives the second gear to move left and right. The third spring drives the rack shaft to move left and right in the chute, playing a buffering role to prevent the liquid crystal display screen from being bumped and damaged.

[0040] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
