[0002] In the manufacturing process of displays, the assembly process is a crucial step in ensuring product quality and performance. Currently, display assembly mainly relies on manual operation or simple tooling. However, these methods have many shortcomings.

[0003] During manual assembly, operators need to manually position and install the glass substrate, drive board, and control board, which is not only inefficient but also easily affected by human factors, resulting in low positioning accuracy and thus affecting the display effect and stability of the screen.

[0004] Existing simple tooling can only position glass substrates of a single size. Furthermore, the operation is complicated when positioning and installing drive boards and control boards, making it difficult to complete the task quickly and accurately, which hinders the improvement of production efficiency.

[0005] Therefore, those skilled in the art have provided an efficient display assembly and positioning fixture to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Reference Figures 1-5 This embodiment provides a high-efficiency display screen assembly positioning fixture, including a fixture base 1. The upper end of the fixture base 1 is fixedly connected to a support column 3. There are four support columns 3 arranged in a matrix. The upper ends of the four support columns 3 are fixedly installed with positioning frames 4. The upper surfaces of the positioning frames 4 are fixedly installed with brackets 5 on both sides. The upper end of the brackets 5 is provided with a sliding hole 11 at the center. The inner walls on both sides of the sliding hole 11 are provided with locking grooves 26. The sliding hole 11 is slidably connected with guide columns 20. The lower ends of the two guide columns 20 are fixedly connected to positioning plates 6 through connecting rods 19. The upper ends of the positioning plates 6 are respectively provided with a drive plate positioning groove 21 and a control plate positioning groove 22.

[0027] Example 2

[0028] Reference Figures 1-5This embodiment is based on the previous embodiment, but differs in that the upper end of the positioning frame 4 has four sliding grooves 7 arranged in a matrix, and each of the four sliding grooves 7 has a slider 8 slidably connected to it; the upper end of each slider 8 is fixedly connected to a clamping plate 9, and the front end of each clamping plate 9 is glued with a rubber pad 10; the lower end of each slider 8 is fixedly connected to a connecting block 16; a rotating disk 12 is rotatably connected to the center of the lower end of the positioning frame 4, and the bottom of the rotating disk 12 has four arc-shaped grooves 13, the positions of which correspond to the sliding grooves 7; each of the four arc-shaped grooves 13 has a sliding block 8 slidably connected to it. A guide rod 14 is connected to a corresponding connecting block 16 via a connecting arm 15; a rotating shaft 17 is fixedly connected to the lower end of the rotating disk 12, and a rotating handle 18 is fixedly connected to the lower end of the rotating shaft 17; a through telescopic cavity 24 is provided on the outer wall of the guide post 20 near its lower end, and a compression spring 25 is provided inside the telescopic cavity 24. Bullet-shaped lock heads 23 are fixedly connected to both ends of the compression spring 25, and the bullet-shaped lock heads 23 are slidably connected to the inner wall of the telescopic cavity 24; mounting holes 2 are provided at the upper end of the tooling base 1 near the four corners, and the tooling base 1 can be fixed to the workbench with bolts.

[0029] Working principle: The operator rotates the handle 18, which drives the rotating shaft 17 to rotate. The rotating shaft 17 then drives the rotating disk 12 to rotate. The arc-shaped groove 13 at the bottom of the rotating disk 12 rotates together with the rotating disk 12. Since the guide rod 14 is slidably connected in the arc-shaped groove 13, and the guide rod 14 is fixedly connected to the connecting block 16 at the lower end of the slider 8 through the connecting arm 15, and the slider 8 is slidably connected in the slide groove 7 of the positioning frame 4, the rotation of the arc-shaped groove 13 will cause the guide rod 14 to slide in the arc-shaped groove 13, and drive the slider 8 to slide in the slide groove 7 through the connecting arm 15. The four sliders 8 move towards or away from the center at the same time, thereby causing the clamping plate 9 to extend and retract concentrically, realizing the clamping of glass substrates of different sizes. The rubber pad 10 at the front end of the clamping plate 9 plays a buffering role during the clamping process to prevent damage to the glass substrate. After the glass substrate is clamped and fixed, the operator presses the guide post 20, and the telescopic cavity on the outer wall of the guide post 20 near the lower end... The guide post 20 is equipped with a compression spring 25 and a bullet-shaped lock head 23. When the guide post 20 is pressed, the bullet-shaped lock head 23 is compressed and retracts into the telescopic cavity 24, thereby sliding out of the lock groove 26 and releasing the limit of the guide post 20. At this time, the guide post 20 can slide downward in the sliding hole 11, and drive the positioning plate 6 to move downward through the connecting rod 19. The drive plate positioning groove 21 and the control plate positioning groove 22 on the positioning plate 6 correspond to the installation positions of the drive plate and control plate on the glass substrate, respectively. When the positioning plate 6 descends to fit the glass substrate, the installation positions of the drive plate and control plate can be quickly determined. After installation, the operator lifts the positioning plate 6, and the guide post 20 slides upward. When the bullet-shaped lock head 23 moves to the position of the lock groove 26, the rebound force of the compression spring 25 pushes the bullet-shaped lock head 23 out of the telescopic cavity 24 into the lock groove 26, thereby fixing the positioning plate 6 and fixing the positioning plate 6 on the top for the next assembly operation.
