[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0022] Example 1: An easy-tear adhesive installation device for an LED display screen used in an industrial hydraulic press includes a work frame 1. The work frame 1 has a working component 2, a moving component 3, a detection component 4, and a moving bracket 5 arranged inside. The moving bracket 5 is equipped with an easy-tear adhesive installer 6 and a fixed horizontal plate 7. The fixed horizontal plate 7 is equipped with an easy-tear adhesive roller pressing assembly 8. The easy-tear adhesive roller pressing assembly 8 includes a horizontal pressing assembly 81, a vertical pressing assembly 82, and an auxiliary pressure-relieving assembly 83. The horizontal pressing assembly 81 is arranged on the fixed horizontal plate 7, and the vertical pressing assembly 82 and the auxiliary pressure-relieving assembly 83 are arranged on the horizontal pressing assembly 81.

[0023] The horizontal pressing assembly 81 includes a multi-rod telescopic member 811 disposed on a fixed horizontal plate 7. A U-shaped frame 812 is disposed below the multi-rod telescopic member 811. The multi-rod telescopic member 811 is connected to the U-shaped frame 812. A first roller 813 is rotatably disposed on the inner side of the U-shaped frame 812.

[0024] In this embodiment, when the LED display screen with the easy-tear sticker applied to the movable component 3 is transferred to the next processing step and passes through the horizontal pressing component 81, the multi-rod telescopic device 811 is activated. The multi-rod telescopic device 811 drives the U-shaped frame 812 and the first roller 813 set on it to move towards the LED display screen on the movable component 3. When the first roller 813 is applied to the upper surface of the LED display screen on the movable component 3 and the movable component 3 is in the process of moving, the first roller 813 performs horizontal rolling pressing on the easy-tear sticker applied to the upper surface of the LED display screen.

[0025] By using the horizontal pressing component 81, the easy-tear stickers applied to the upper surface of the LED display screen can be horizontally rolled, which can improve the adhesion stability of the easy-tear stickers applied to the LED display screen, and can also eliminate air bubbles and wrinkles between the easy-tear stickers and the LED screen, thereby improving the flatness and long-term stability of the easy-tear stickers.

[0026] Example 2: An easy-tear adhesive installation device for an LED display screen used in an industrial hydraulic press, wherein the longitudinal pressure assembly 82 includes a first synchronous gear 821 rotatably disposed on the front and rear side walls of the U-shaped frame 812, the two first synchronous gears 821 respectively docking with the two ends of the first roller 813, a rotating block 822 and a first transmission gear 823 are rotatably disposed on one side of the first synchronous gear 821, and a second synchronous gear 824 is disposed on both the rotating block 822 and the first transmission gear 823.

[0027] The first synchronous gear 821 is connected to the adjacent second synchronous gear 824 by a toothed belt 825, and the two adjacent second synchronous gears 824 are connected by a toothed belt 825. A second transmission gear 826 is rotatably provided on one side of the first transmission gear 823, and the first transmission gear 823 meshes with the second transmission gear 826 on one side. A bidirectional screw 827 is rotatably provided on the inner side of the U-shaped frame 812.

[0028] The rotating block 822, the first transmission gear 823, and the second transmission gear 826 on the U-shaped frame 812 are connected to one end of the bidirectional screw 827 on the inner side of the U-shaped frame 812. A second roller 828 is provided on the inner side of the U-shaped frame 812. The second roller 828 is located between the two bidirectional screws 827. Connecting blocks 829 are provided at both ends of the second roller 828. The connecting blocks 829 at both ends of the second roller 828 are connected to the two bidirectional screws 827 by threads.

[0029] A third roller 8210 is provided on one side of the second roller 828. The third roller 8210 is located on one side of a bidirectional screw 827. A guide rod 8211 is provided on one side of the third roller 8210. The guide rod 8211 is connected to the inner side of the U-shaped frame 812. Connecting blocks 829 are connected to both ends of the third roller 8210. One end of the connecting block 829 of the third roller 8210 is connected to the bidirectional screw 827 by threads. The other end of the connecting block 829 of the third roller 8210 is sleeved on the guide rod 8211.

[0030] It should be noted that the ends of the second roller 828 and the third roller 8210 are rounded.

[0031] In this embodiment, when the first roller 813 is attached to the upper surface of the LED display screen on the movable member 3, the second roller 828 and the third roller 8210 are also attached to the upper surface of the LED display screen on the movable member 3. The first roller 813 rotates during the rolling process of the LED display screen, driving the first synchronous gear 821 to rotate. The first synchronous gear 821, through the toothed belt 825, drives the second synchronous gear 824, the first transmission gear 823, and the second transmission gear 826 meshing with the first transmission gear 823 to rotate. The second synchronous gear 824 and the first transmission gear 821... 23. The second transmission gear 826 drives the bidirectional screw 827 inside the U-shaped frame 812 to rotate. The bidirectional screw 827 drives the second roller 828 and the third roller 8210 inside the U-shaped frame 812 to move back and forth. The movement of the second roller 828 and the third roller 8210 longitudinally rolls the easy-tear sticker affixed to the upper surface of the LED display screen on the moving part 3. Since the bidirectional screw 827 connected to the second transmission gear 826 rotates in the opposite direction to the bidirectional screw 827 driven by the second synchronous gear 824, the movement directions of the second roller 828 and the third roller 8210 inside the U-shaped frame 812 are opposite.

[0032] By setting the longitudinal pressing component 82, the easy-tear stickers affixed to the upper surface of the LED display screen can be longitudinally rolled, which can further improve the rolling effect between the easy-tear stickers and the LED screen. The second rolling roller 828 and the third rolling roller 8210 move in opposite longitudinal directions to form cross rolling, thus avoiding the problem of localized pressure leakage on the easy-tear stickers on the LED display screen.

[0033] Example 3: An easy-tear adhesive installation device for an LED display screen used in an industrial hydraulic press, wherein the auxiliary pressure relief component 83 includes a connecting plate 831 disposed on the upper end face of a U-shaped frame 812, a receiving cavity 832 is provided on the inner side of the connecting plate 831, a helical spring 833 is disposed at the bottom end of the inner side of the receiving cavity 832, a fixing plate 834 is slidably disposed on the inner side of the receiving cavity 832, one end of the helical spring 833 on the inner side of the receiving cavity 832 is connected to the fixing plate 834 on the inner side of the receiving cavity 832, and the output end of the multi-rod telescopic device 811 passes through the connecting plate 831 and is connected to the fixing plate 834 on the inner side of the connecting plate 831.

[0034] In this embodiment, when the multi-rod telescopic device 811 pushes the first roller 813 against the LED display screen on the movable part 3 after the easy-tear adhesive has been applied, the first roller 813 will be subjected to an upward reverse force. At this time, the helical spring 833 is subjected to force and deforms. The helical spring 833 buffers the upward reverse force of the first roller 813, thereby preventing the LED display screen from being bumped by the first roller 813.

[0035] The auxiliary pressure relief component 83 absorbs the reverse impact force during the rolling process through the helical spring 833, avoiding screen bumps and excessive compression deformation of easy-to-remove stickers caused by rigid contact.

[0036] The moving component 3 includes a rodless cylinder 31 disposed on one side of the bottom inner side of the work frame 1 and an LED display screen placement plate 32 disposed on the rodless cylinder 31. The detection component 4 includes a support rod 41 disposed on the bottom inner side of the work frame 1 and a connecting horizontal plate 42 disposed on the support rod 41. A detector 43 is disposed on the connecting horizontal plate 42.

[0037] The working component 2 includes a mounting platform 21 located at the bottom inner side of the working frame 1. An easy-tear adhesive tape feed roll 22 is mounted on the mounting platform 21, and an easy-tear adhesive tape body is wound on the feed roll 22. A drive wheel 23 is mounted on the mounting platform 21, and a guide wheel 24 is located on one side of the drive wheel 23. A first easy-tear adhesive tape placement plate 25 is located on one side of the mounting platform 21, and a second easy-tear adhesive tape placement plate 27 is located on one side of the first easy-tear adhesive tape placement plate 25. Multiple sets of positioning holes are formed on the upper surface of the first easy-tear adhesive tape placement plate 25, with two holes in each set. Two limiting guide plates 26 are provided on the upper surface of the first easy-tear adhesive tape placement plate 25, and two positioning pins are provided on each limiting guide plate 26. The positioning pins on the limiting guide plates 26 are inserted into a set of positioning holes on the upper surface of the first easy-tear adhesive tape placement plate 25, and the easy-tear adhesive tape body located on the upper surface of the first easy-tear adhesive tape placement plate 25 is positioned between the two limiting guide plates 26.

[0038] The upper surface of the second easy-tear sticker placement plate 27 is provided with an easy-tear sticker pressing member 29. The easy-tear sticker pressing member 29 includes a pressure plate 291. The lower surface of the pressure plate 291 is rotatably provided with a plurality of rolling rollers 292. The pressure plate 291 is mounted on the second easy-tear sticker placement plate 27 by screws.

[0039] The guide wheel 24 is set on the easy-tear sticker feeding roll 22. One end of the easy-tear sticker passes through the drive wheel 23 and the guide wheel 24 and is successively placed on the upper surface of the first easy-tear sticker placement plate 25 and the second easy-tear sticker placement plate 27. The easy-tear sticker on the upper surface of the first easy-tear sticker placement plate 25 is located between two limiting guide plates 26. The easy-tear sticker on the upper surface of the second easy-tear sticker placement plate 27 passes through the lower surface of the pressure plate 291, and multiple rolling rollers 292 on the lower surface of the pressure plate 291 roll on the upper surface of the easy-tear sticker.

[0040] It should be noted that the working principle of how to apply easy-tear stickers to LED displays is not considered as an improvement in this application; the specific principle can be found in existing technologies.

[0041] Working principle of this invention: When the LED display screen with the easy-tear sticker applied to the LED display placement plate 32 is transferred to the next processing step via the rodless cylinder 31 and passes through the horizontal pressing component 81, the multi-rod telescopic device 811 is activated. The multi-rod telescopic device 811 drives the U-shaped frame 812 and the first pressure roller 813 mounted on it to move towards the LED display screen on the LED display placement plate 32. When the first pressure roller 813 is applied to the upper surface of the LED display screen on the moving part 3 and the moving part 3 is in the process of moving, the first pressure roller 813 horizontally presses the easy-tear sticker applied to the upper surface of the LED display screen. During the rolling process, the first roller 813 is pressed against the upper surface of the LED display screen on the LED display screen placement plate 32. Simultaneously, the second roller 828 and the third roller 8210 are also pressed against the upper surface of the LED display screen on the LED display screen placement plate 32. The first roller 813 rotates during the rolling process, driving the first synchronous gear 821 to rotate. The first synchronous gear 821, through the toothed belt 825, drives the second synchronous gear 824, the first transmission gear 823, and the first transmission gear... The second transmission gear 826, meshing with wheel 823, rotates. The second synchronous gear 824, the first transmission gear 823, and the second transmission gear 826 drive the bidirectional screw 827 inside the U-shaped frame 812 to rotate. The bidirectional screw 827 drives the second pressure roller 828 and the third pressure roller 8210 inside the U-shaped frame 812 to move back and forth. The movement of the second pressure roller 828 and the third pressure roller 8210 longitudinally rolls the easy-tear sticker affixed to the upper surface of the LED display screen on the moving part 3. Because the bidirectional screw 827, which is connected to the second transmission gear 826, rotates in the same direction as the first transmission gear 823, the rotation of the second synchronous gear 824, the first transmission gear 823, and the second transmission gear 826 drives the bidirectional screw 827 inside the U-shaped frame 812 to rotate. The two synchronous gears 824 drive the bidirectional screw 827 in opposite directions, which makes the movement directions of the second roller 828 and the third roller 8210 inside the U-shaped frame 812 opposite. When the multi-rod telescopic device 811 pushes the first roller 813 against the LED display screen that has been easily peeled off on the moving part 3, the first roller 813 will be subjected to an upward reverse force. At this time, the helical spring 833 is deformed by the force, and the helical spring 833 buffers the upward reverse force of the first roller 813, thereby preventing the LED display screen from being bumped by the first roller 813.

[0042] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
