Description

Technical Field

[0001] The utility model belongs to the technical field of processing positioning, in particular to a positioning device for processing an LED display screen. Background Art

[0002] LED electronic displays utilize semiconductor light-emitting diodes (LEDs) to control displays. They consist of tens to hundreds of thousands of evenly arranged LED pixels. Different materials can be used to create LED pixels of varying colors, enabling the display of text, graphics, images, animations, market information, videos, and recordings. Currently, red, green, and yellow LEDs are the most widely used, while blue and pure green LEDs have reached practical application. During the manufacturing process, LED displays require positioning before processing. However, existing positioning devices typically only position the display piece at a time, requiring removal after processing and subsequent positioning. This inability to achieve continuous positioning is detrimental to improving production efficiency.

[0003] Publication number CN221088796U discloses a rapid positioning assembly for LED liquid crystal display screens. By combining a slider with a display fixing mechanism, an electric telescopic rod drives the movement of a first connecting rod. This method allows for rapid positioning of the lower end of the LED liquid crystal display screen, improving the efficiency of the rapid positioning assembly. By combining a fixing block with a positioning mechanism at the upper end of the display screen, a first motor drives a worm, which in turn drives a worm wheel. This method forces two clamping plates to abut against the outer wall of the LED display screen, securing the upper end of the LED display screen and preventing damage to the screen. This improves the performance of the rapid positioning assembly. However, it still cannot achieve continuous positioning, resulting in low production efficiency. Utility Model Content

[0028] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0031] The existing devices for positioning display screens are mostly structures such as positioning frames. Their disadvantage is that they can only position one display screen. After processing, they need to be removed and then processed on another display screen. Automatic continuous positioning processing cannot be achieved, and their efficiency is relatively slow. In view of this, a positioning device that can perform automatic continuous positioning processing is designed. The specific structure is as follows.

[0032] Please refer to Figures 1 to 5 The positioning device for processing an LED display screen includes two side walls 1, a plurality of supporting legs 2, a conveying device and a positioning frame 8. The plurality of supporting legs 2 are connected to the bottom of the side wall 1 in an array-like distributed connection design. The bottom of the supporting legs 2 is connected to a grounding plate fixed to the ground. The grounding plate is fixed to the ground through a grounding member. The positioning frame 8 is arranged between the tops of the two side walls 1.

[0033] The conveying equipment can be any existing equipment with a conveying function. Here, the belt conveyor is used to illustrate the specific operation.

[0034] The conveying equipment includes two conveying wheels 3 and a conveying belt 4. The conveying belt 4 is sleeved between the outer periphery of the conveying wheels 3. A central shaft is provided in the center of the conveying wheel 3. The central shaft is rotatably connected to the side wall 1 through a bearing. A rotating motor 5 is installed on one side of one of the side walls 1. The driving end of the rotating motor 5 passes through the side wall 1 and is connected to one of the central shafts through a coupling. A plurality of dial plates 6 are connected to the top of the conveying belt 4. The plurality of dial plates 6 are equidistantly distributed in an array. The dial plates 6 play an auxiliary conveying role and can be used to increase the pushing force. A stabilizing plate 7 is provided between the two side walls 1 to enhance stability and prevent falling. The top of the stabilizing plate 7 contacts the inner top of the conveying belt 4 to prevent falling.

[0035] See also Figures 1 to 5In order to achieve positioning, the positioning frame 8 is located above the conveying part of the conveying device. Here, it is necessary to ensure that the feeding plate 6 is located below the positioning frame 8, mainly to avoid interference between the conveying part and the positioning frame 8. The bottom two sides of the positioning frame 8 are fixed to the top of the side wall 1;

[0036] A positioning groove 9 is provided on one side of the positioning frame 8. The positioning groove 9 allows the display screen to pass through and its inner circumference is adapted to the display screen. A flared arc design is provided between the side of the positioning frame 8 facing the conveying device and the positioning groove 9, and the inner wall of the flared arc design is provided with a ball portion 13. Through the design of the flared arc and the ball portion 13, the display screen can be guided into the space of the positioning groove 9 in accordance with the conveying device.

[0037] Two hydraulic rods (not shown in the figure) are embedded on both sides of the center of the positioning groove 9 of the positioning frame 8 to assist in clamping and aligning. The positioning frame 8 is provided with retractable limit plates 14 on both sides of the inner wall of the positioning groove 9. The inner side of the limit plate 14 is connected to an extension column 19.

[0038] There are concave cavities on both sides of the positioning groove 9. The extension column 19 is located in the center of the concave cavity. The outer ring plate 15 is bonded to the outer periphery of the extension column 19. The extension column 19 is made of metal. A compression spring 16 is provided on one side of the outer ring plate 15. The compression spring 16 is designed to surround the extension column 19. An electromagnet 18 for controlling the extension is provided on one side of the extension column 19.

[0039] In order to avoid the influence of magnetic attraction, the components around the extension column 19 are all designed with non-metallic materials. Therefore, when the electromagnet 18 is running, it can attract the extension column 19. The bottom of the positioning frame 8 can be provided with a bottom cover plate connected to the concave cavity for easy maintenance.

[0040] A top frame 11 is provided on one side of the top of the positioning frame 8. The top frame 11 is designed as an inverted U-shaped structure. A hydraulic rod 12 is installed on the top of the top frame 11. The driving end of the hydraulic rod 12 passes through the top frame 11 and is connected to a limiting plate 14. The limiting plate 14 is designed to pass through the positioning frame 8 to limit one side of the display screen.

[0041] The above components and electrical equipment are all existing technologies or existing feasible technologies. Their working principles, sizes and models are irrelevant to the functions of this application, so they will not be described in detail. They are all controlled by remote control switches.

[0042] How it works

[0043] When the positioning device for processing an LED display screen is used, the display screen is placed on top of the conveyor belt 4 and between the corresponding dial plates 6 (the display screen needs to be roughly aligned when placed, but does not need to be swung accurately). The rotary motor 5 is started to drive the conveyor wheel 3 to rotate, causing the conveyor belt 4 to rotate, so that the conveyor belt 4 drives the display screen to move;

[0044] When the display screen is in the flared position, the guidance of the ball bearing part and the flared design can correct its position so that it can enter the new positioning groove. After entering, the transportation will be restricted by the blocking plate 10. At the same time, when it reaches the positioning position, the electromagnet 18 stops running, and the extension column 19 is acted upon by the elastic force of the compression spring 16, so that the limit plate 14 pops up and blocks and limits the display screen. In conjunction with the embedded hydraulic rod, the positioning of the display screen can be completed, and processing can be carried out through external equipment.
