[0002] A display screen positioning device used in LCD screen manufacturing is a specialized device used to precisely fix and determine the position of the display screen during the LCD screen manufacturing process. Through mechanical structures, sensors, or other positioning technologies, it ensures that the display screen maintains a stable and accurate position during processing steps such as cutting, assembly, and coating, avoiding the impact of positional deviation on processing accuracy and product quality, and providing positional assurance for the efficient and high-quality production of LCD screens.

[0003] Existing Chinese patent document CN221160078U discloses a display screen positioning device for LCD screen processing, including a base platform; a drive unit mounted on the base platform; a display screen positioning unit hinged to the top front end of the drive unit; an auxiliary positioning unit fixedly installed on the outer surface of the front end of the display screen positioning unit; and a lifting unit fixedly installed on the inner wall of the middle part of the base platform. This patent uses the cooperation of the drive unit and the display screen positioning unit to pre-fix and clamp the LCD screen to be processed, and uses the auxiliary positioning unit to further enhance the fixing effect of the LCD screen, ensuring stability during LCD screen processing. At the same time, the lifting unit allows the user to lift the LCD screen according to the processing needs and adjust the processing angle, thereby improving the processing effect of the LCD screen. However, this display screen positioning device still has shortcomings: it clamps the display screen structure through two sets of display screen positioning units, and the clamping structure of the display screen positioning units is horizontal, which can only clamp flat display screens and cannot adapt to the clamping requirements of curved display screens, making it difficult to meet the actual use requirements. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned display screen positioning device uses two sets of display screen positioning units to clamp the display screen structure. The clamping structure of the display screen positioning unit is horizontal and can only clamp flat display screens. It cannot adapt to the clamping requirements of curved display screens and cannot meet the actual use requirements. Therefore, this utility model provides a display screen positioning device for LCD display screen processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a display screen positioning device for LCD screen processing, comprising: a base plate, a movable slot frame embedded in the center line of the base plate, a servo motor fixedly connected to one side of the movable slot frame, a bidirectional screw provided at the output end of the servo motor, and movable slider one and movable slider two symmetrically screwed onto the outer side of the bidirectional screw, a vertical plate one fixedly connected to the top of movable slider one, a vertical plate two fixedly connected to the top of movable slider two, a rotating motor fixedly connected to one side of vertical plate two, a rotating shaft provided at the output end of the rotating motor, and a side plate one fixedly connected to the end face of the rotating shaft. A driven shaft is inserted through the top of the upright plate. A limit ring is fixed to the outer side of one end of the driven shaft. A side plate is fixed to the other end of the driven shaft. Multiple telescopic connecting rods are connected between the side plate and the side plate. A rod groove is opened through one end of the side plate. A round rod is inserted through the rod groove. A tension spring is fixed to one end of the round rod. A square rod is fixed to the end of the tension spring. An arc-shaped component is fixed to the other end of the square rod. A positioning ring is fixedly sleeved on the other end of the round rod. A positioning block is symmetrically fixed to one side of the positioning ring. An annular groove is opened on one end of the rod groove. Several sets of positioning grooves are arranged in a ring on one side of the annular groove.

[0006] As a further embodiment of this utility model: the first upright plate and the second upright plate are respectively fixed to the top of the first movable slider and the second movable slider, and rotate with the bidirectional screw driven by the servo motor, thereby causing the first movable slider and the second movable slider to move relative to each other.

[0007] As a further improvement of this utility model, the first side plate and the second side plate are telescopically connected by a multi-section telescopic linkage structure arranged symmetrically in four directions, so that when the rotating motor drives the rotating shaft to rotate, the driven shaft rotates accordingly, driving the first side plate and the second side plate to rotate synchronously, without affecting the relative movement of the two.

[0008] As a further improvement of this utility model: the limiting ring is set on the outer side of one end of the driven shaft, and works with the second side plate to prevent the driven shaft from coming out of the second vertical plate.

[0009] As a further embodiment of this utility model: the round rod and the square rod are telescopically connected to each other, and are elastically connected by a tension spring; the specifications of the positioning ring are adapted to the specifications of the annular groove; the positioning block is adapted to the position specifications of the positioning groove; and a handle is fixedly connected to the end face of the round rod for holding and stretching the round rod and the square rod.

[0010] As a further embodiment of this utility model: an arc-shaped rubber block is fixedly connected to the bottom surface inside the bow-shaped part, a clamping screw hole is opened through the top of the bow-shaped part, a clamping stud is screwed through the clamping screw hole, and an arc-shaped rubber block is rotatably connected to the end of the clamping stud.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a servo motor drives a bidirectional screw to move the two side plates synchronously and centered. The clamping width can be precisely adjusted to adapt to different sizes of display screens, avoiding offset caused by force on one side. At the same time, the four-way symmetrical multi-section telescopic connecting rod between the side plates allows the two side plates to adaptively adjust the distance during rotation. In addition, the structure of the rotating motor driving the rotating shaft and the driven shaft enables the display screen to flexibly rotate at any angle.

[0013] 2. The bow-shaped component composed of a spring structure in this utility model can flexibly adjust the rotation angle to simultaneously adapt to the clamping requirements of flat or curved display screens. The adjustable rotation angle design increases the applicability of the equipment. The bow-shaped component can flexibly adapt to the clamping requirements of display screens of different thicknesses by moving two sets of arc-shaped rubber blocks closer and further apart.

The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 7In this embodiment of the present invention, a display screen positioning device for LCD screen processing includes: a base plate 1, a movable slot frame 2 embedded in the center line of the base plate 1, a servo motor 3 fixedly connected to one side of the movable slot frame 2, a bidirectional screw 4 provided at the output end of the servo motor 3, and movable slider 1 5 and movable slider 2 7 symmetrically screwed onto the outer side of the bidirectional screw 4, a vertical plate 1 6 fixedly connected to the top of movable slider 1 5, a vertical plate 2 8 fixedly connected to the top of movable slider 2 7, a rotary motor 9 fixedly connected to one side of vertical plate 2 8, a rotary shaft 10 provided at the output end of the rotary motor 9, a side plate 11 fixedly connected to the end face of the rotary shaft 10, and a driven shaft 12 passing through the top of vertical plate 1 6. A limiting ring 13 is fixedly connected to the outer side of one end of the driven shaft 12, and a second side plate 14 is fixedly connected to the other end face of the driven shaft 12. A multi-section telescopic connecting rod 15 is connected between the first side plate 11 and the second side plate 14. A rod groove 16 is opened through one end of the first side plate 11, and a round rod 17 is inserted inside the rod groove 16. A tension spring 18 is fixedly connected to one end of the round rod 17, and a square rod 19 is fixedly connected to the end of the tension spring 18. An arc-shaped piece 20 is fixedly connected to the other end of the square rod 19. A positioning ring 21 is fixedly sleeved on the other end of the round rod 17. A positioning block 22 is symmetrically fixed to one side of the positioning ring 21. An annular groove 23 is opened at one end of the inner side of the rod groove 16, and several sets of positioning grooves 24 are arranged in a ring on one side inside the annular groove 23.

[0025] Reference Figures 1 to 7 The first vertical plate 6 and the second vertical plate 8 are respectively fixed to the top of the first movable slider 5 and the second movable slider 7. Driven by the servo motor 3, the bidirectional screw 4 rotates, causing the first movable slider 5 and the second movable slider 7 to move relative to each other.

[0026] The above scheme is adopted: the first upright plate 6 and the second upright plate 8 are fixed on the top of the first movable slider 5 and the second movable slider 7 respectively. The screw threads of the slider and the bidirectional screw 4 are opposite. When the servo motor 3 drives the bidirectional screw 4 to rotate, the two sliders move relative to each other in sync, ensuring that the upright plates on both sides move in the center, realizing the precise clamping and positioning of the display screen, adapting to the display screen structure of different width specifications, and avoiding the offset problem caused by uneven force on one side, thus improving the positioning accuracy.

[0027] Reference Figures 1 to 7 Side plate 11 and side plate 2 14 are telescopically connected by a multi-section telescopic connecting rod 15 structure arranged symmetrically in four directions. When the rotating motor 9 drives the rotating shaft 10 to rotate, the driven shaft 12 rotates accordingly, driving side plate 11 and side plate 2 14 to rotate synchronously, without affecting their relative movement.

[0028] The above solution is adopted: Side plate 11 and side plate 2 14 are connected by four sets of symmetrically distributed multi-section telescopic connecting rods 15. The rotating shaft 10 and the driven shaft 12 are coaxially set. When the rotating motor 9 drives the side plate to rotate, the driven shaft 12 rotates synchronously to ensure that the two side plates always remain parallel and avoid damage to the display screen due to angular deviation. The multi-section telescopic connecting rods 15 allow the distance between the side plates to be adaptively adjusted and maintain a stable connection during rotation, which is suitable for the positioning requirements of display screens of different sizes.

[0029] Reference Figures 1 to 7 The limiting ring 13 is located on the outer side of one end of the driven shaft 12, and works with the side plate 2 14 to prevent the driven shaft 12 from coming out of the vertical plate 2 8.

[0030] The above solution is adopted: the limiting ring 13 is fixed to the outside of the driven shaft 12, and its diameter is larger than the shaft hole on the vertical plate 8. This prevents the driven shaft from coming off the vertical plate under frequent rotation or external force, ensuring the stability and reliability of the rotating structure, extending the service life of the equipment, and reducing maintenance costs.

[0031] Reference Figures 1 to 7 The round rod 17 and the square rod 19 are telescopically connected to each other and are elastically connected by a tension spring 18. The specifications of the positioning ring 21 are adapted to the specifications of the annular groove 23, and the position specifications of the positioning block 22 are adapted to the positioning groove 24. A handle 29 is fixedly connected to the end face of the round rod 17 for holding and stretching the round rod 17 and the square rod 19.

[0032] The above solution involves a round rod 17 passing through a rod groove 16 and telescopically connected to a square rod 19. The two are further elastically connected via a tension spring 18. The round rod 17, i.e., the positioning ring 21, can be pulled out by holding the handle 29. The rotation angle of the bow-shaped component 20 can be adjusted according to the curvature of the display screen. After angle adjustment, releasing the handle 29 causes the positioning ring 21 to drive the positioning block 22 back into the annular groove 23. Two sets of symmetrical positioning blocks 22 extend into the corresponding positioning grooves 24 to fix the rotation angle of the positioning ring 21. Several sets of positioning grooves 24 provide a wider range of adjustment. This angle adjustment method is quick and convenient, and the adjustable bow-shaped component 20 can flexibly adapt to the clamping requirements of display screens with different curvatures.

[0033] Reference Figures 1 to 7 An arc-shaped rubber block 25 is fixed to the bottom surface inside the bow-shaped part 20. A clamping screw hole 26 is opened through the top of the bow-shaped part 20. A clamping stud 27 is screwed through the clamping screw hole 26. An arc-shaped rubber block 28 is rotatably connected to the end of the clamping stud 27.

[0034] The above solution is adopted: the inside of the bow-shaped component 20 is clamped by the arc-shaped adhesive block 1 25 and the arc-shaped adhesive block 28. The arc-shaped adhesive block 28 is controlled by the degree to which the clamping screw 27 connected to it engages with the clamping screw hole 26, thereby controlling its lifting height, that is, controlling the distance between the arc-shaped adhesive block 1 25 and the arc-shaped adhesive block 28, so as to flexibly adapt to the clamping requirements of displays of different thicknesses.

[0035] The working principle of this utility model is as follows: When in use, the servo motor 3 drives the bidirectional screw 4 to rotate in the movable slot frame 2 embedded in the center of the equipment base plate 1. Since the moving slider 1 5 and the moving slider 2 7 are opposite to the screw thread direction, the two can move relative to each other synchronously, driving the upright plate 1 6 and the upright plate 2 8 fixed to the top to move in the center, thereby achieving precise clamping of the display screen in the width direction. This design can be adapted to display screens of different width specifications and avoids one-sided force deviation.

[0036] The rotating motor 9 on one side of the upright plate 2 8 drives the side plate 11 to rotate through the rotating shaft 10. At the same time, the driven shaft 12 at the top of the upright plate 1 6 drives the side plate 2 14 to rotate synchronously under the constraint of the limiting ring 13, ensuring that the two side plates are always parallel. The side plate 11 and the side plate 2 14 are connected by a four-way symmetrical multi-section telescopic connecting rod 15. The four sets of multi-section telescopic connecting rods 15 allow the two side plates to adaptively adjust the spacing during rotation, which not only ensures structural stability but also adapts to the positioning requirements of different sized displays.

[0037] The round rod 17 passes through the rod groove 16 and is telescopically connected to the square rod 19. The two are further elastically telescopically connected by a tension spring 18. The round rod 17, i.e. the positioning ring 21, can be pulled out by holding the handle 29. The rotation angle of the bow-shaped part 20 can be adjusted according to the curvature of the display screen. After the angle adjustment is completed, the handle 29 is released, so that the positioning ring 21 drives the positioning block 22 to be pressed back into the annular groove 23. Two sets of symmetrical positioning blocks 22 extend into the corresponding positioning grooves 24 to fix the rotation angle of the positioning ring 21. Several sets of positioning grooves 24 provide a larger range of adjustment. This angle adjustment method is quick and convenient. The adjustable bow-shaped part 20 can flexibly adapt to the clamping requirements of display screens with different curvatures.

[0038] The inside of the bow-shaped component 20 is clamped by the first curved adhesive block 25 and the second curved adhesive block 28. The second curved adhesive block 28 is controlled by the degree to which the clamping screw 27, which is rotatably connected to it, engages with the clamping screw hole 26, thereby controlling its lifting height, that is, controlling the distance between the first curved adhesive block 25 and the second curved adhesive block 28, so as to flexibly adapt to the clamping requirements of displays of different thicknesses.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
