Description

Technical Field

[0001] The utility model belongs to the technical field of glue applicators, and in particular to a positioning glue applicator for LED display processing. Background Technique

[0002] The glue applicator, also known as a coating machine, is mainly a mechanical device used to apply liquid glue to the surface of textiles, paper boxes or leather. During the production and processing of LED displays, a glue applicator is used to glue-seal the display panel and PCB board of the LED display. However, when applying glue to the LED display, after the glue spraying nozzle sprays the glue, some residual glue is likely to adhere to the discharge pipe, and this glue is not easy to fall off, resulting in the residual glue dripping onto the equipment at any time, causing pollution to the equipment. Also, when replacing the LED display, it is likely to fall onto the position of the LED display where glue application is not required, causing pollution to the LED display. Therefore, it is necessary to clean the dripping glue, which reduces the efficiency of glue application to the LED display.

[0003] For example, in the existing Chinese Patent Publication No.: CN218251195U, a positioning glue applicator for LED display processing, it has: "including a fixed bottom plate, on both sides of the top of the fixed bottom plate, vertical rods are installed, at the top of the vertical rods, top rods are installed, at the top of the top rods, a hydraulic cylinder is installed, at the transmission position at the bottom of the hydraulic cylinder, a hydraulic telescopic rod is connected, and at the bottom of the hydraulic telescopic rod, a sliding rod is installed."

[0004] It can be seen that this cited patent document has the problem that the residual glue is likely to drip onto the equipment or the LED display. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a positioning glue applicator for LED display processing to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A positioning glue applicator for LED display processing, including a base, on both sides of the base, top blocks are fixedly provided through brackets, inside the cavity of the top block, a movable block is provided, on the inner side wall and one side surface of the top block, a driving structure for driving the movable block to move is provided, at the bottom surface of the movable block, an electric push rod is installed, at the output end of the electric push rod, a rectangular block is fixedly provided horizontally, at the bottom surface of the rectangular block, a glue applicator head for applying glue is provided, on one side surface of the rectangular block, a hinge plate is hinged through a pin shaft, at the lower half of one side surface of the movable block, an L-shaped connecting frame is fixedly provided, at the lower half of the inner side wall of the connecting frame, a movable frame is also hinged through a pin shaft, one end of the movable frame is hinged to one side surface of the hinge plate, at the other end of the movable frame, a material receiving box for collecting residual glue is provided, and the material receiving box is located directly below the glue applicator head.

[0007] Preferably, the driving structure includes a driving motor fixed on one side of the top block and a threaded shaft connected to the output shaft of the driving motor.

[0008] Preferably, the threaded shaft is arranged in the inner cavity of the top block, and one end of the threaded shaft is rotatably connected to the inner side wall of the top block.

[0009] Preferably, a limiting rod is horizontally fixed on the inner side wall of the top block above the threaded shaft, and the movable block is slidably sleeved on the periphery of the limiting rod.

[0012] Preferably, the piston rods of the two air cylinders both penetrate through the vertical plates and are fixed with clamping plates for clamping the LED display screen.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] For the positioning glue applicator for LED display screen processing, through the setting of the glue storage box, the glue liquid left by the glue applicator head can be received. The settings of the hinge plate, the connecting frame and the movable frame make the glue storage box deflect to one side when the glue applicator head moves downward, avoiding the glue storage box affecting the glue application of the glue applicator head. On the contrary, when the glue applicator head moves upward, the glue storage box will move directly below the glue applicator head, so as to receive the glue liquid left at the nozzle of the glue applicator head, avoiding the problem that the left glue liquid will drip onto the equipment or the LED display screen, and then causing pollution to the equipment or the LED display screen, and thus the need to clean the glue liquid, improving the efficiency of glue application to the LED display screen.

Detailed implementation manners

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0023] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the drawings shown in the present utility model, and are hereby explained together.

[0024] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0025] As Figures 1 to 4 shown, a positioning glue applicator for LED display processing includes a base 1. Both side surfaces of the base 1 are fixedly provided with top blocks 2 through brackets. The top blocks 2 are arranged directly above the base 1, and the bottom surface of the top block 2 is hollowed out. An inner cavity of the top block 2 is provided with a movable block 3. A driving structure for driving the movable block 3 to move is provided on the inner side wall and one side surface of the top block 2. The driving structure includes a drive motor 14 fixedly provided on one side surface of the top block 2 and a threaded shaft 15 connected to the output shaft of the drive motor 14. The drive motor 14 can rotate forward and backward. The threaded shaft 15 is arranged in the inner cavity of the top block 2 and one end of the threaded shaft 15 is rotatably connected to the inner side wall of the top block 2. By turning on the drive motor 14, the drive motor 14 can drive the threaded shaft 15 to rotate, thereby driving the movable block 3 to move around the threaded shaft 15. And in cooperation with the forward and reverse rotation of the drive motor 14, the movable block 3 makes a reciprocating motion. A limiting rod 16 is horizontally and fixedly provided on the inner side wall of the top block 2 and above the threaded shaft 15. The movable block 3 is slidably sleeved around the limiting rod 16. When the movable block 3 moves, it will move around the limiting rod 16, so that the limiting rod 16 limits the movement of the movable block 3.

[0026] An electric push rod 4 is installed on the bottom surface of the movable block 3. A rectangular block 5 is fixedly arranged horizontally at the output end of the electric push rod 4. A glue applicator head 6 for applying glue is arranged on the bottom surface of the rectangular block 5. When the movable block 3 moves along the circumferential side of the threaded shaft 15, it will drive the electric push rod 4, the rectangular block 5 and the glue applicator head 6 to move synchronously, so that the glue applicator head 6 can move above the required glue application position. At this time, the electric push rod 4 is turned on, and the electric push rod 4 drives the rectangular block 5 and the glue applicator head 6 to move downward, so that the glue applicator head 6 moves above the glue application position, and then the glue application operation can be carried out. The glue applicator head 6 is a prior art, and it only needs to be able to extrude glue onto the LED display screen.

[0027] One side surface of the rectangular block 5 is hinged with a hinge plate 7 through a pin shaft. The lower half of one side surface of the movable block 3 is fixedly provided with an L-shaped connecting frame 8. The lower half of the inner side wall of the connecting frame 8 is also hinged with a movable frame 9 through a pin shaft. One end of the movable frame 9 is hinged with one side surface of the hinge plate 7, and the hinge between the movable frame 9 and the hinge plate 7 is also hinged through a pin shaft. When the electric push rod 4 drives the rectangular block 5 to move downward, the rectangular block 5 will drive the hinge plate 7 to move downward, and the hinge plate 7 will drive the movable frame 9 to move downward. Since the middle end of the movable frame 9 is hinged to the lower half of the connecting frame 8, when the hinge plate 7 drives the movable frame 9 to move downward, the movable frame 9 will make a circular motion with the hinge point with the connecting frame 8 as the origin. When the rectangular block 5 moves downward, the movable frame 9 will rotate counterclockwise. However, when the rectangular block 5 moves upward, it will drive the hinge plate 7 and the movable frame 9 to move in the reverse direction, so that the movable frame 9 rotates clockwise.

[0028] A material receiving box 10 for collecting residual glue is arranged at the other end of the movable frame 9. The material receiving box 10 is located directly below the glue applicator head 6. In the initial state, the material receiving box 10 is located directly below the glue applicator head 6, so that the material receiving box 10 can receive the glue remaining at the nozzle of the glue applicator head 6. However, when the glue applicator head 6 moves downward for the glue application operation, the glue applicator head 6 will drive the movable frame 9 to rotate counterclockwise through the rectangular block 5, the hinge plate 7 and the connecting frame 8, so as to drive the material receiving box 10 to rotate counterclockwise, so that the material receiving box 10 can move to one side of the glue applicator head 6 to avoid the material receiving box 10 affecting the glue application of the glue applicator head 6. However, after the glue applicator head 6 finishes applying glue and moves upward, it will drive the hinge plate 7 to move in the reverse direction through the rectangular block 5, so as to drive the movable frame 9 to rotate clockwise, so that the material receiving box 10 can rotate clockwise, and the material receiving box 10 can move to directly below the glue applicator head 6, so that the material receiving box 10 can receive the glue remaining at the nozzle of the glue applicator head 6, so that the dropped glue can fall into the material receiving box 10, avoiding the problem that the remaining glue will drip onto the equipment or the LED display screen, thereby causing pollution to the equipment or the LED display screen, and thus the need to clean the glue, improving the efficiency of applying glue to the LED display screen.

[0029] A through groove 11 for placing the material storage box 10 is provided on one side of the movable frame 9 and directly below the glue application head 6. A cushion block is fixedly provided on the peripheral side of the upper half of the material storage box 10. Due to the setting of the cushion block, after the material storage box 10 is placed in the inner cavity of the through groove 11, the cushion block will be above the movable frame 9, enabling the material storage box 10 to be placed in the inner cavity of the through groove 11. Screw holes 12 are provided on one side of the movable frame 9 and one side of the material storage box 10. After the material storage box 10 is placed in the inner cavity of the through groove 11, the screw holes 12 on one side of the material storage box 10 will be aligned with the screw holes 12 on one side of the movable frame 9. Bolts 13 are threadedly connected in the inner cavities of the two aligned screw holes 12, so that the position of the material storage box 10 can be fixed through the bolts 13 and the screw holes 12, preventing the material storage box 10 from falling off the through groove 11 when it is tilted and also facilitating the disassembly of the material storage box 10 to clean the glue in the material storage box 10. A semicircular baffle is provided on one side of the top surface of the material storage box 10, and one side of the baffle is provided with a hollow structure and is communicated with the inner cavity of the material storage box 10, enabling the baffle to block the glue and preventing the glue inside the material storage box 10 from overflowing from the inner cavity of the material storage box 10 when the material storage box 10 is tilted.

[0030] A workbench 17 is provided on the top surface of the base 1. Cylinders 18 are fixedly provided on both sides of the top surface of the workbench 17 through vertical plates. The piston rods of the two cylinders 18 penetrate through the vertical plates and are fixedly provided with clamping plates 19 for clamping the LED display screen. After the LED display screen is placed on the top surface of the workbench 17, the two cylinders 18 are turned on. The two cylinders 18 can drive the two clamping plates 19 to move in opposite directions, enabling the two clamping plates 19 to clamp and fix the LED display screen, facilitating subsequent glue application. On one side of the top surface of the base 1, a hydraulic cylinder (not shown) can be installed. The piston rod of the hydraulic cylinder is fixedly provided on one side of the workbench 17, enabling the hydraulic cylinder to drive the workbench 17 to move longitudinally and cooperate with the driving structure to drive the transverse movement of the glue application head 6, so that the glue application head 6 can apply the glue to any position of the LED display screen.

[0031] Working principle:

[0032] For the positioning and glue - applying machine used for processing LED display screens, place the LED display screen to be glue - applied on the top surface of the workbench 17, and clamp and fix the LED display screen through the air cylinder 18 and the clamping plate 19. At this time, turn on the driving structure, and it can drive the glue - applying head 6 to move above the position where glue needs to be applied. Then turn on the electric push rod 4. The electric push rod 4 drives the glue - applying head 6 to move downward through the rectangular block 5, and the rectangular block 5 will drive the hinged plate 7 to move downward. Since one end of the hinged plate 7 is hinged to one end of the movable frame 9, and the middle part of the movable frame 9 is hinged to the lower half of the connecting frame 8, when the rectangular block 5 drives the hinged plate 7 to move downward, the hinged plate 7 will pull the movable frame 9, enabling the movable frame 9 to rotate counterclockwise with the hinge point with the connecting frame 8 as the origin, so that the movable frame 9 drives the material - containing box 10 to rotate counterclockwise, allowing the material - containing box 10 to move to one side of the glue - applying head 6. Then the glue - applying head 6 can move to the position where glue needs to be applied for glue - applying. After the glue - applying is completed, the electric push rod 4 drives the glue - applying head 6 to move upward through the rectangular block 5, which can drive the hinged plate 7 and the movable frame 9 to move in the opposite direction, enabling the material - containing box 10 to rotate clockwise and move to directly below the glue - applying head 6, allowing the material - containing box 10 to receive the glue at the nozzle of the glue - applying head 6, avoiding the problem that the remaining glue drops onto the equipment or the LED display screen, thereby causing pollution to the equipment or the LED display screen and the need to clean the glue, and improving the efficiency of glue - applying to the LED display screen.
