[0002] LED digital tubes are digital display devices composed of multiple LEDs (light-emitting diodes) used to display numbers and other characters. After assembly, LED digital tubes require a protective film to be applied to their surface.

[0003] A search revealed Chinese patent CN220948738U, which discloses an automatic LED digital tube film applicator. Its structure includes a main body, an alarm light, a door, and side channels. The alarm light is located on the top of the main body to prevent damage to the digital tubes. However, the following drawback remains: after the LED digital tubes are processed, they need to be disassembled before installing unprocessed ones. However, the protective film applicator stops working during the disassembly and installation process, resulting in wasted time and significantly reduced work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective film bonding device for LED digital tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The protective film bonding device for LED digital tubes includes a base plate. A slide rail is fixedly connected to the upper surface of the base plate, and a slider is slidably connected inside the slide rail. Support plates are fixedly connected to both sides of the slider, and the slide rail contacts the support plates to support them. Placement plates are placed on the upper surfaces of the two support plates. Multiple placement slots for placing LED digital tubes are opened on the upper surface of the placement plates. The top of the base plate is provided with an insertion assembly for auxiliary fixing of the support plates. A support frame is fixedly connected to one side of the base plate, and a cylinder is fixedly connected to the top of the support frame. One end of the pneumatic rod of the cylinder passes through the support frame and is provided with an elastic bonding assembly for bonding the LED digital tubes.

[0007] As a further embodiment of this utility model, the insertion assembly includes multiple sliding openings, all of which are opened on the upper surface of the base plate and penetrate the base plate. A card holder is slidably connected in two adjacent sliding openings. Both sides of the card holder are provided with inclined surfaces, so that the upper part of the card holder forms a trapezoidal structure. The bottom of the support plate is provided with two card slots, and the card holder is inserted into the card slots. Two springs are provided in the card holder, and the two ends of the springs are fixed to the card holder and the base plate respectively.

[0008] As a further embodiment of this utility model, the card holder is fixedly connected to two sides below the base plate to block the card holder.

[0009] As a further embodiment of this utility model, the elastic bonding component includes a connecting plate, which is fixedly connected to one end of the pneumatic rod of the cylinder. A compression spring is fixedly connected to the bottom of the connecting plate, and an adsorption block for adsorbing the protective film is fixedly connected to the bottom end of the compression spring.

[0010] As a further embodiment of this utility model, two telescopic rods are fixedly connected to the bottom of the connecting plate, and one end of the telescopic part of each of the two telescopic rods is fixed to the adsorption block.

[0011] As a further embodiment of this utility model, the upper surface of the support plate is fixedly connected with positioning rods at the four corners, and the bottom of the placement plate is provided with positioning grooves at the four corners.

[0012] As a further embodiment of this utility model, the positioning rod is aligned vertically with the positioning groove, and the positioning rod is inserted into the positioning groove to position the placement plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up two support plates, two placement plates with LED digital tubes are placed on the two support plates respectively. At this time, one placement plate is directly below the adsorption block, so the LED digital tubes on one placement plate are first coated with film. After the film is coated, the other support plate is moved directly below the adsorption block, so the LED digital tubes on the other placement plate are coated with film. At the same time, the coated LED digital tubes can be removed and new LED digital tubes can be placed. This cycle is repeated, so that the LED digital tubes can be coated without interruption, saving time and improving work efficiency.

[0015] 2. By using the interlocking assembly, when the support plate moves directly below the adsorption block, the interlocking assembly helps to fix the support plate, thus preventing it from moving easily and improving the stability of the bonding device.

[0016] 3. By using the positioning rod and positioning groove together, when the placement plate is placed on the support plate, the positioning rod on the support plate is inserted into the positioning groove on the placement plate, so that the placement plate can be positioned and placed, avoiding the displacement of the placement plate and improving the convenience of using the bonding device.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4The protective film bonding device for LED digital tubes includes a base plate 11. A slide rail 9 is bolted to the upper surface of the base plate 11. A slider 19 is slidably connected within the slide rail 9. Support plates 8 are welded to both sides of the slider 19, and the slide rail 9 contacts the support plates 8 to support them. Placement plates 7 are placed on the upper surfaces of both support plates 8. Multiple placement slots 10 for placing LED digital tubes are formed on the upper surface of the placement plates 7. The LED digital tubes are placed into the placement slots 10 on the placement plates 7, and then the placement plates 7 with the LED digital tubes are placed onto the support plates 8. The top of the base plate 11 has an insertion assembly for auxiliary fixing of the support plates 8. A support frame 4 is bolted to one side of the base plate 11. The top of the support frame 4... A cylinder 3 is fixed to the unit by bolts. One end of the pneumatic rod of the cylinder 3 passes through the support frame 4 and is equipped with an elastic bonding component for bonding the LED digital tube. After the placement plate 7 is placed, the elastic bonding component applies film to the LED digital tube. After the film is applied, the slider 19 is moved along the slide rail 9. The slider 19 will drive the two support plates 8 to move, so that the other support plate 8 moves to the film application position, so that the elastic bonding component continues to bond the LED digital tube. At the same time, the film-applied LED digital tube is removed from the support plate 8, and then a new LED digital tube is placed on the support plate 8. This cycle is repeated, so that the film can be applied to the LED digital tube without interruption, saving time and improving work efficiency.

[0024] In this invention, the insertion assembly includes multiple sliding openings, all of which are formed on the upper surface of the base plate 11 and penetrate the base plate 11. A retainer 13 is slidably connected within two adjacent sliding openings. Both sides of the retainer 13 have inclined surfaces 14, forming a trapezoidal structure in the upper half of the retainer 13. Two slots 12 are formed at the bottom of the support plate 8, and the retainer 13 is inserted into the slots 12. Two springs 16 are provided inside the retainer 13, with both ends of the springs 16 fixed to the retainer 13 and the base plate 11 respectively. The two sides of the retainer 13 are located below the base plate 11. A stop block 15 is welded to block the card holder 13. During the movement of one of the support plates 8, the card holder 13 is pushed downward by the inclined surface 14 of the card holder 13, so that the card holder 13 squeezes the spring 16 and disengages from the card slot 12. When the other support plate 8 moves to the film application position, the card holder 13 will move upward and reset by the force of the spring 16 and insert into the card slot 12 on the other support plate 8, thereby providing auxiliary fixation for the support plate 8, so that the support plate 8 will not move easily, and at the same time, the movement of the support plate 8 can be positioned.

[0025] The elastic bonding assembly includes a connecting plate 1, which is bolted to one end of the pneumatic rod of a cylinder 3. A compression spring 2 is welded to the bottom of the connecting plate 1, and an adsorption block 6 for adsorbing the protective film is welded to the bottom end of the compression spring 2. When film application is required, the cylinder 3 is activated, extending and pushing the connecting plate 1 downward. The connecting plate 1, through the compression spring 2, moves the adsorption block 6 downward, causing the protective film adsorbed on the adsorption block 6 to contact the LED digital tube. At this time, the connecting plate 1 continues to move downward, while the adsorption block 6 cannot move, thus causing the connecting plate 1 to compress the compression spring 2. This, in turn, causes the compression spring 2 to apply pressure to the adsorption block 6, resulting in elastic compression between the adsorption block 6 and the protective film and the LED digital tube, allowing the protective film to better adhere to the LED digital tube. The bottom of the connecting plate 1 is fixed with two telescopic rods 5 by bolts. One end of the telescopic part of each telescopic rod 5 is fixed to the adsorption block 6. When the connecting plate 1 compresses the compression spring 2, it also compresses the telescopic rods 5 to retract, thereby preventing the connecting plate 1 and the adsorption block 6 from shifting when the connecting plate 1 compresses the compression spring 2. The upper surface of the support plate 8 is welded with positioning rods 17 at the four corners. The bottom of the placement plate 7 is provided with positioning grooves 18 at the four corners. The positioning rods 17 and the positioning grooves 18 are aligned vertically and inserted into the positioning grooves 18 to position the placement plate 7. When placing the placement plate 7, the positioning rods 17 on the support plate 8 are inserted into the positioning grooves 18 on the placement plate 7 to position the placement plate 7.

[0026] Working Principle: When needed, place the LED digital tube into the placement slot 10 on the placement plate 7, and then place the placement plate 7 with the LED digital tube in place onto the support plate 8. During placement, the positioning rod 17 on the support plate 8 is inserted into the positioning slot 18 on the placement plate 7 to position the placement plate 7. After placement, one of the placement plates 7 is directly below the adsorption block 6. Activate the cylinder 3; the cylinder 3 extends and pushes the connecting plate 1 downwards. The connecting plate 1, through the compression spring 2, moves the adsorption block 6 downwards, allowing the protective film adsorbed on the adsorption block 6 to contact the LED digital tube. The connecting plate 1 continues to move downwards, while the adsorption block 6 remains stationary. This causes the connecting plate 1 to compress the compression spring 2, which in turn applies pressure to the adsorption block 6. This elastic compression between the adsorption block 6 and the protective film ensures better adhesion between the protective film and the LED digital tube. After the protective film is applied, the cylinder 3 is activated to retract, resetting the adsorption block 6. Then, the slider 19 moves along the slide rail 9, causing the two support plates 8 to move. During this movement, one support plate 8 pushes the card holder 13 downwards via the inclined surface 14 of the card holder 13, causing the card holder 13 to press against the spring 16 and disengage from the card slot 12. When the other support plate 8 moves directly below the adsorption block 6, the card holder 13 moves upwards and resets under the force of the spring 16, inserting into the card slot 12 on the other support plate 8, thus providing auxiliary fixation for the support plate 8. At this time, the LED digital tube on the other support plate 8 is applied with the adsorption block 6, and the applied LED digital tube is removed from the support plate 8. Then, a new LED digital tube is placed on the support plate 8. This cycle is repeated, allowing for uninterrupted application of the LED digital tube film, saving time and improving work efficiency.
