Description

Technical Field

[0001] This utility model relates to the field of LED displays, and specifically to a multi-layer material bonding device for LED displays. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels used to display various information such as text, images, and videos. Integrating microelectronics, computer technology, and information processing, LED electronic displays offer advantages such as vibrant colors, wide dynamic range, high brightness, long lifespan, and stable and reliable operation. LED displays are widely used in commercial media, cultural performances, sports venues, information dissemination, news releases, and securities trading, meeting the needs of diverse environments.

[0003] Chinese patent discloses a film-applying device for LED displays (authorization announcement number CN 114852407B). This patented technology, "through the use of a gravity sensing mechanism, can adjust the squeegee pressure according to the different weights of the display screen. Simultaneously, it can sense the position of the display screen to prevent damage to the edges during film application, improving the application efficiency and demonstrating the device's multi-functionality." It solves the problem that "many film-applying devices require manual pre-positioning of the film before insertion into the device, resulting in low efficiency and a low success rate. Currently, there are some packaging and laminating mechanisms, but they typically function as packaging, wrapping the LED screen in the film and then vacuuming it, but they lack adhesiveness and need to be removed after installation." However, this patent still has the following problems:

[0004] The patent cannot accurately position the display screen and the protective film, which makes it easy for misalignment to occur, leading to film application failure. Furthermore, the positioning structure of the display screen cannot be disassembled, making it impossible to apply film to display screens of different sizes, thus reducing the practicality of the device.

[0022] Please see Figures 1-6This embodiment provides a multi-layer material bonding device for LED displays, including a reaction chamber 1 and an electric slider 2. The electric slider 2 is installed at the bottom of the reaction chamber 1. A lower seat 11 is installed on the upper surface of the electric slider 2. A lower cavity 13 is screwed to the upper surface of the lower seat 11 via a lower bolt 12. An upper cylinder 14 is installed on the upper surface of the reaction chamber 1. An upper seat 15 is installed at the output end of the upper cylinder 14. An upper cavity 17 is screwed to the bottom of the upper seat 15 via an upper bolt 16. Suction cups 18 are embedded in the top of the upper cavity 17 near the four corners. A control panel 27 is installed on the left side of the reaction chamber 1. The control panel 27 and the electric slider 2 are electrically connected. The electric slider 2 is a linear guide slider structure. A motor drives a lead screw to rotate, thereby controlling the linear movement of the device. During operation, the control panel 27... The control panel 27 contains a PLC program to control the operation of each device. The display screen is positioned in the lower cavity 13. The electric slider 2 is activated, moving the lower cavity 13 backward so that the display screen enters the reaction chamber 1. A protective film is placed on top of the upper cavity 17. The suction cup 18 is activated to attract and fix the upper surface of the protective film. The upper cylinder 14 is activated, moving the protective film downward so that it accurately adheres to the display screen surface, eliminating the need for manual film application and avoiding errors. The lower bolt 12 structure facilitates disassembly and replacement of the lower cavity 13, and the upper bolt 16 structure facilitates disassembly and replacement of the upper cavity 17. This allows for individual film application to display screens of different specifications, further improving the device's versatility.

[0023] The upper end face of the upper seat 15 is provided with a fixing groove. An adjusting screw 19 is rotatably installed in the fixing groove through a bearing. The adjusting screw 19 has symmetrical left and right threads with opposite directions. The outer side wall of the adjusting screw 19 is symmetrically screwed with a first slider. A positioning frame 21 is installed on the upper end face of the first slider. The positioning frame 21 is inserted into the left and right side walls of the upper cavity 17. During operation, the positioning frame 21 is inserted and fixed to the upper cavity 17, which further improves the stability of the connection between the upper cavity 17 and the upper seat 15. Rotating the adjusting screw 19 can drive the positioning frame 21 to move outward and open.

[0024] The upper seat 15 has positioning grooves near the four corners on its upper end face. The upper cavity 17 has positioning posts 22 installed at the bottom. The positioning posts 22 are arranged in the positioning grooves. During operation, the positioning posts 22 position the upper cavity 17 to prevent it from shifting.

[0025] A push plate 23 is installed at the bottom of the lower cavity 13. Side frames 24 are symmetrically installed on the upper surface of the push plate 23. The side frames 24 are connected to the left and right side walls of the lower cavity 13 by sliding fit. The upper surface of the push plate 23 is made of cotton pad material. During operation, after the screen film is applied, the side frames 24 are pulled to move the screen upward, making it easy to remove the screen and avoid damage from bumps.

[0026] The lower seat 11 is equipped with a front frame 25 on its front end face, and a cover 26 is installed on the front end face of the front frame 25. The rear end face of the cover 26 is installed on the front end face of the reaction chamber 1 by a snap-fit. During operation, the cover 26 seals and protects the reaction chamber 1, effectively reducing the impact of external dust.

[0027] A rear frame 28 is installed on the rear end face of the lower seat 11. A pressure sensor 29 is embedded in the rear end face of the reaction chamber 1. A warning light 291 is installed on the left end face of the reaction chamber 1. Both the pressure sensor 29 and the warning light 291 are electrically connected to the control panel 27. During operation, when the lower seat 11 moves backward, the rear frame 28 presses against the surface of the pressure sensor 29, causing the warning light 291 to light up. This ensures the accuracy of the position of the lower seat 11 and avoids misalignment that could lead to inaccurate film application and thus the risk of film application failure.

[0028] In actual operation, the control panel 27 contains a PLC program that controls the operation of each device. The display screen is placed in the lower cavity 13 for positioning. The electric slider 2 is activated, moving the lower cavity 13 backward so that the display screen enters the reaction chamber 1. The protective film is placed on top of the upper cavity 17. The suction cup 18 is activated to attract and fix the upper surface of the protective film. The upper cylinder 14 is activated, moving the protective film downward so that it can be accurately attached to the surface of the display screen without manual film application, avoiding errors. The lower bolt 12 structure facilitates the disassembly and replacement of the lower cavity 13, and the upper bolt 16 structure facilitates the disassembly and replacement of the upper cavity 17. This allows for film application to display screens of different specifications, further improving the versatility of the device.
