Description

Technical Field

[0001] This utility model relates to the field of positioning devices, specifically a display screen positioning device for LCD screen processing. Background Technology

[0002] During the actual processing of the display screen, it needs to be clamped and positioned. In the clamping and positioning process, the clamping blocks on both sides need to be attached to the sides of the display screen assembly. Therefore, during the clamping process, it is necessary to manually place the display screen in the center position and then adjust the position of the clamping blocks on both sides to make them fit the sides of the display screen. When adjusting the position of the clamping blocks, bolts and buckle structures may be used. Therefore, manual clamping of the display screen is quite cumbersome. To address this, we propose a display screen positioning device for LCD screen processing. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-3A display screen positioning device for LCD screen processing includes a rectangular plate 1. Sliding sliding frames 3 are provided on both sides of the top of the rectangular plate 1. A driving structure for driving the sliding frames 3 to move is provided on the bottom of the rectangular plate 1. A snap-fit ​​protrusion 5 is fixedly installed on the top of each sliding frame 3. A bearing platform 6 is fixedly installed on the surface of the rectangular plate 1 in the area between the two sliding frames 3. The driving structure includes a hinge assembly, a cylinder 16, and a fixing block 15. The cylinder 16 is fixedly installed on the bottom of the rectangular plate 1. A fixing block 15 is fixedly installed on the bottom of one of the sliding frames 3. The telescopic shaft of the cylinder 16 is fixedly connected to the fixing block 15. The hinge assembly is located on the bottom of the rectangular plate 1, and both sides of the hinge assembly are hinged to the bottom of the sliding frames 3 on both sides. The hinge assembly includes a rotating shaft 12 rotatably installed on the bottom of the rectangular plate 1, a connecting rod 13, and... The hinge rod 14 and the rotating shaft 12 are fixedly mounted with connecting rods 13 on both sides. The free ends of both sides of the connecting rod 13 are hinged with hinge rods 14. The free ends of the hinge rods 14 are hinged to the bottom of the sliding frame 3. When the output shaft of the cylinder 16 extends or retracts, it will drive the sliding frame 3 on one side to move laterally. At this time, the hinge rod 14 moves, driving one side of the connecting rod 13 to move. The rotating shaft 12 rotates, thereby driving the connecting rod 13 and the hinge rod 14 on the other side to rotate, thereby driving the sliding frame 3 on the other side to move. This achieves synchronous displacement of the sliding frames 3 on both sides. When it is necessary to position and clamp the display screen, the drive structure drives the sliding frames 3 on both sides to move synchronously. Then, the snap-fit ​​protrusion 5 fits against the side of the display screen for clamping. This device does not require manual adjustment of the position of the clamping block or manual tightening of screws for fixing. It is simple, convenient and fast.

[0019] Furthermore, two raised guide rails 2 are fixedly installed on the rectangular plate 1, the sliding frame 3 is frame-shaped, and a slide rail block 4 is integrally formed on the inner side of the sliding frame 3 corresponding to the position of the raised guide rail 2. The slide rail block 4 is slidably engaged with the raised guide rail 2.

[0020] Furthermore, rectangular grooves 8 are provided on the corresponding side walls of the two snap-fit ​​protrusions 5. The rectangular grooves 8 penetrate one side wall of the snap-fit ​​protrusion 5. Multiple sets of springs 9 are fixedly installed on the inner wall of the rectangular grooves 8. A concave block 10 with a concave cross-section is fixedly installed at the end of the spring 9. A roller 11 is rotatably installed on the inner side of the concave block 10. When the transmission equipment transmits the display screen that needs to be positioned and clamped to the support platform 6, the display screen may be placed at an angle. At this time, the roller 11 will contact one side wall of the display screen. With the guidance of the conveyor belt, the movement of the display screen will drive the roller 11 to roll, preventing the corners of the display screen from directly hitting the snap-fit ​​protrusion 5 and causing damage during the guidance process. During the clamping process, the roller 11 fits against the side of the display screen. Then the clamping force gradually increases. At this time, the spring 9 contracts, and the concave block 10 and the roller 11 are gradually collected into the interior of the rectangular groove 8.

[0021] Furthermore, rubber blocks 7 are embedded on the side wall where the two snap-fit ​​protrusions 5 are close to each other. The rubber blocks 7 can prevent damage to the side of the display screen when the snap-fit ​​protrusions 5 clamp it.

[0022] Working principle: When the transmission device transmits the display screen that needs to be positioned and clamped to the support platform 6, it then performs clamping and positioning. The cylinder 16 is activated, and its telescopic shaft extends and retracts, which drives the sliding frame 3 on one side to move laterally. At this time, the hinge rod 14 moves, which drives one side of the connecting rod 13 to move. The rotating shaft 12 rotates, thereby driving the connecting rod 13 and the hinge rod 14 on the other side to rotate, thereby driving the sliding frame 3 on the other side to move. This achieves synchronous displacement of the sliding frames 3 on both sides until the locking protrusion 5 fits against the side of the display screen for clamping and positioning.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
