Description

Technical Field

[0001] The utility model relates to the technical field of diffusion plate assembly, in particular to an automatic diffusion plate assembly device. Background Technique

[0002] The biggest feature of the diffusion plate is that it causes great interference to light. No matter what the original designed light distribution curve is, as long as the light passes through the diffusion plate, it will change the beam angle to 160-176°. After the diffusion plate is produced, it needs to be assembled by an assembly device, and before assembly, the assembly device will clean and remove dust from the surface of the diffusion plate through a cleaning roller.

[0003] After the cleaning roller in the existing diffusion plate assembly device is used for a long time, it needs to be replaced. Since the cleaning roller is generally fixed and installed by screw and nut fixing parts, special tools are required for both disassembly and assembly, resulting in relatively cumbersome steps and inconvenience. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages in the prior art: after the cleaning roller in the existing diffusion plate assembly device is used for a long time, it needs to be replaced. Since the cleaning roller is generally fixed and installed by screw and nut fixing parts, special tools are required for both disassembly and assembly, resulting in relatively cumbersome steps and inconvenience. Therefore, an automatic diffusion plate assembly device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic diffusion plate assembly device includes an electric sliding table and a cleaning roller. The upper surface of the sliding seat of the electric sliding table is fixedly installed with a mounting block. A rotating port is opened on the surface of the mounting block, and a rotating ring is rotatably installed in the rotating port. One end of the cleaning roller passes through the rotating ring;

[0008] Preferably, the elastic member includes a torsion spring sleeved on the rotating shaft. A fixing block is fixedly installed at one end of the rotating shaft located outside the hollow cylinder. The two ends of the torsion spring are respectively fixedly connected to the fixing block and the installation disc.

[0009] Preferably, sliding rods are symmetrically and fixedly installed on the side wall at one end of the cleaning roller, and sliding openings for inserting the two sliding rods are symmetrically formed in the inner ring wall of the rotating ring.

[0010] Preferably, an L-shaped oil inlet hole communicating with the rotating opening is formed on the surface of the mounting block, an oil storage tank is fixedly installed on the upper surface of the sliding seat of the electric sliding table, and the lubricating oil in the oil storage tank is supplied to the oil inlet hole through an oil supply assembly.

[0011] Preferably, the oil supply assembly includes an oil outlet pipe fixedly installed at one end in the oil inlet hole, a hollow rod with one end designed to be closed, and a piston rod slidably and sealingly inserted into the hollow rod.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present utility model.

[0023] Refer to Figures 1 - 4 , an automatic assembly diffusion plate device, including an electric slide table 1 and a cleaning roller 5. The upper surface of the sliding seat of the electric slide table 1 is fixedly installed with a mounting block 2. A rotating opening 3 is opened on the surface of the mounting block 2. A rotating ring 4 is rotatably installed in the rotating opening 3. One end of the cleaning roller 5 passes through the rotating ring 4.

[0024] Symmetrically fixed on the surface of the rotating ring 4 are connecting rods 6. Between the ends of the two connecting rods 6 is fixedly installed a mounting plate 7. Fixedly installed on the surface of the mounting plate 7 is a hollow cylinder 8. At the end of the hollow cylinder 8 away from the mounting plate 7 is fixedly installed a suction cup 9. One end of the cleaning roller 5 is horizontally opened with a slot 10 for the insertion of the hollow cylinder 8 and the suction cup 9. An arc-shaped opening 11 is opened on the surface of the hollow cylinder 8. A through opening communicating with the inside of the hollow cylinder 8 is opened on the surface of the mounting plate 7. Rotatably installed in the through opening in a sealed manner is a rotating shaft 12. At the end of the rotating shaft 12 located inside the hollow cylinder 8 is fixedly installed, through a connecting rod, a plugging plate 13 for covering the arc-shaped opening 11. The rotating shaft 12 is connected to the mounting plate 7 through an elastic member. The elastic member includes a torsion spring 14 sleeved on the rotating shaft 12. At the end of the rotating shaft 12 located outside the hollow cylinder 8 is fixedly installed a fixed block. The two ends of the torsion spring 14 are respectively fixedly connected to the fixed block and the mounting plate 7.

[0025] When it is necessary to install the cleaning roller 5, only the end of the cleaning roller 5 provided with the slot 10 needs to pass through the inner ring of the rotating ring 4. At this time, both the hollow cylinder 8 and the suction cup 9 will enter the slot 10. And as the cleaning roller 5 moves, the suction cup 9 will abut against the slot wall of the slot 10. Under the action of the pressing force, the suction cup 9 will deform, and the gas in the suction cup 9 will escape from the gap between the contact surface of the suction cup 9 and the slot wall of the slot 10, so as to adsorb the cleaning roller 5, and the installation of the cleaning roller 5 can be completed.

[0026] When it is necessary to disassemble the cleaning roller 5, only the rotation of the rotating shaft 12 needs to be controlled externally to make the blocking plate 13 rotate to no longer cover the arc-shaped opening 11. At this time, the gas located outside will enter the hollow cylinder 8 from the arc-shaped opening 11, so as to automatically release the adsorption of the suction cup 9 on the cleaning roller 5, which is convenient and fast. And when the rotating shaft 12 is released, at this time, the rotating shaft 12 will quickly drive the blocking plate 13 to rotate and reset under the elastic potential energy of the torsion spring 14. After the rotation and reset, the blocking plate 13 will cover the arc-shaped opening 11 again.

[0027] On the side wall at one end of the cleaning roller 5, sliding rods 16 are symmetrically and fixedly installed. On the inner ring wall of the rotating ring 4, sliding openings 15 for inserting the two sliding rods 16 are symmetrically opened. When installing the cleaning roller 5, the two sliding rods 16 can be respectively aligned and inserted into the two sliding openings 15 to reduce the external force influence on the suction cup 9 when the cleaning roller 5 is rotating.

[0028] The installation block 2 is provided with an L-shaped oil inlet hole 17 communicating with the rotating port 3. On the upper surface of the sliding seat of the electric sliding table 1, an oil storage tank 18 is fixedly installed. The lubricating oil in the oil storage tank 18 is supplied to the oil inlet hole 17 through an oil supply component. The oil supply component includes an oil outlet pipe 19 fixedly installed at one end in the oil inlet hole 17, a hollow rod 20 with a closed end at one end, and a piston rod 21 slidably and sealingly inserted into the hollow rod 20. The closed end of the hollow rod 20 is fixedly connected to the oil outlet pipe 19 and is in communication. The hollow rod 20 is connected to the oil storage tank 18 through an oil inlet pipe 22. One end of the piston rod 21 is fixedly installed with a moving plate. On the surface of the moving plate, a spring rod 23 is fixedly installed. The end of the spring rod 23 away from the moving plate is fixedly connected to the surface of the installation block 2. One-way valves are provided in both the oil inlet pipe 22 and the oil outlet pipe 19. The conduction direction of the one-way valve in the oil inlet pipe 22 is from the inside of the oil storage tank 18 to the inside of the hollow rod 20, and the conduction direction of the one-way valve in the oil outlet pipe 19 is from the inside of the hollow rod 20 to the oil inlet hole 17.

[0029] Before the cleaning roller 5 cleans the dust on the surface of the diffusion plate, the moving plate can be controlled to move towards the mounting block 2, so that the piston rod 21 moves into the hollow rod 20. At this time, the spring rod 23 will contract, the volume inside the hollow rod 20 becomes smaller, and the pressure increases. The lubricating oil located inside the hollow rod 20 will then enter the oil inlet hole 17 from the oil outlet pipe 19, and will act between the outer ring wall of the rotating ring 4 and the wall of the rotating port 3, which can play a role in lubricating and reducing the friction between the contact surfaces of the rotating ring 4 and the rotating port 3. Then, after releasing the moving plate, the piston rod 21 and the moving plate will quickly move back to their original positions under the elastic potential energy of the spring rod 23. At this time, the volume inside the hollow rod 20 becomes larger, the pressure decreases, and the lubricating oil located in the oil storage tank 18 will enter the hollow rod 20 from the oil inlet pipe 22 to prepare for the next lubrication.

[0030] In the present utility model, when the cleaning roller 5 needs to be installed, only the end of the cleaning roller 5 provided with the slot 10 needs to pass through the inner ring of the rotating ring 4. At this time, both the hollow cylinder 8 and the suction cup 9 will enter the slot 10. And as the cleaning roller 5 moves, the suction cup 9 will abut against the wall of the slot 10. Under the action of the pressing force, the suction cup 9 will deform, and the gas located inside the suction cup 9 will escape from the gap between the contact surface of the suction cup 9 and the wall of the slot 10, thereby adsorbing the cleaning roller 5, and the installation of the cleaning roller 5 can be completed. When the cleaning roller 5 needs to be disassembled, only by controlling the rotation of the rotating shaft 12 externally, the blocking plate 13 is rotated so that it no longer covers the arc-shaped opening 11. At this time, the gas located outside will enter the hollow cylinder 8 from the arc-shaped opening 11, thereby automatically releasing the adsorption of the suction cup 9 on the cleaning roller 5. It is convenient and fast, avoiding the cumbersome steps of using screw and nut fasteners and without the need to rely on special tools.

[0031] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

[0032] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
