Description

Technical Field

[0001] The present invention relates to the technical field of substrates, and in particular to an organic light-emitting panel substrate cleaning device. Background Art

[0002] The substrate is the basic material for manufacturing PCBs. Generally speaking, the substrate is a copper-clad laminate. During the manufacturing process of single-sided and double-sided printed circuit boards, hole processing, chemical copper plating, electroplating copper, etching and other processes are selectively performed on the substrate material - copper-clad laminate to obtain the required circuit pattern. Organic light-emitting panels are one type of substrates, and usually the substrate processing requires cutting and other processes. At this time, dust will adhere to the surface of the substrate. Therefore, a cleaning device is required to clean the substrate.

[0003] In the process of cleaning the surface of the substrate using a cleaning device, it is necessary to clamp the substrate according to the different structures of the substrate to avoid the substrate being placed directly on the cleaning table. When the cleaning liquid is flushed on its surface, the substrate position will be shifted, thereby affecting the substrate cleaning efficiency. However, when the substrate is processed, it will be cut into different shapes, and the substrate material is relatively brittle, resulting in a mismatched clamping device. When the substrate is clamped during the washing process, the substrate clamping surface will be damaged. For this reason, we propose an organic light-emitting panel substrate cleaning device. Summary of the Invention

[0004] In response to the shortcomings of existing organic light-emitting panel substrate cleaning devices, the present invention provides an organic light-emitting panel substrate cleaning device, which has the advantages of clamping the substrate through a roller. At the same time, the roller can rotate to change the clamping surface, and provides elastic potential energy under the elastic action of spring steel, thereby improving its clamping efficiency and avoiding damage to the substrate, thereby solving the problems raised in the above-mentioned background technology.

[0005] The cleaning agent is connected to the cleaning surface of the cleaning box, and the cleaning agent is connected to the cleaning agent to form a cleaning agent.

[0006] Preferably, a bent spring steel is fixedly connected to the outside of the roller, a protective gasket is fixedly connected to the outside of the spring steel, and the substrate to be cleaned is clamped between the protective gaskets.

[0007] Preferably, a cross bar is fixedly connected to the middle of the circular frame, a cleaning device is movably sleeved on the lower end of the outside of the cross bar, and a cleaning brush is installed at the lower part of the cleaning device.

[0008] Preferably, a filter screen is installed inside the cleaning box and at the lower end of the cleaning tabletop. The filter screen is in an inclined state of ° inside the cleaning box, and the inside of the lower end of the cleaning box is filled with cleaning liquid.

[0009] Preferably, the second connecting plate faces the middle of the cleaning box, and the structure in the middle of the clamping plate is in an arc shape sunken inward.

[0010] Preferably, one-way valves are installed inside the first flow pipe and the second flow pipe. The orientations of the two groups of one-way valves are the same, and the other end of the first flow pipe extends into the cleaning box.

[0011] Preferably, the other end of the second flow pipe is fixedly connected to a water storage tank. Flushing nozzles are fixedly connected to the outside of the water storage tank at equal intervals. The ends of the flushing nozzles are installed on the upper part of the cleaning tabletop, and the flushing nozzles are arranged at equal intervals on the upper part of the cleaning tabletop.

[0012] Preferably, a horizontal chute is opened inside the horizontal slide bar. The rotating rod is in a U shape, and the middle part of the rotating rod is sleeved inside the horizontal chute. A motor is installed at the rear end of the rotating rod.

[0013] Preferably, the inside of the pulley group includes a belt and pulleys. At the same time, one end of the helical gear is fixedly connected to the belt, and the helical gear is meshed and connected to the side surface of the circular frame.

[0014] Compared with the existing organic light-emitting panel substrate cleaning device, the present invention has the following beneficial effects:

[0015] 1. For this organic light-emitting panel substrate cleaning device, the cleaning liquid is transported to the upper part of the cleaning tabletop through the flushing nozzles, so that the substrate can be flushed. At the same time, the cleaning liquid flowing back into the cleaning box is extracted into the extraction box through the first flow pipe. At the same time, the extraction box applies negative pressure to drive the flushing nozzles to flow back and flush, so as to control the recycling of the cleaning liquid and improve the resource utilization rate.

[0016] 2. The organic light-emitting panel substrate cleaning device is clamped at both ends of the clamping plate by rollers. When the two sets of clamping plates are controlled to move inward, the rollers drive the protective gasket to contact the side of the substrate. At the same time, when the substrate is irregularly shaped, the roller angle is adjusted, and the middle of the substrate extends between the two sets of rollers, which makes it convenient to clamp substrates of different shapes. At the same time, the clamping plate is rotated to adjust the cleaning surface of the substrate, thereby improving the stability when clamping substrates of different shapes, avoiding squeezing damage to the substrate, and improving the cleaning efficiency.

[0017] 3. The organic light-emitting panel substrate cleaning device extracts the cleaning liquid by driving the extraction box when the rotating rod rotates. At the same time, when the rotating rod rotates, it can synchronously drive the belt installed inside the pulley group to rotate, and use the belt to drive the helical gear to rotate. At the same time, the helical gear applies power to the rotation of the circular frame, which facilitates the control of the movement of the brush and improves the cleaning efficiency.

By rotating the threaded rod 5, the second connecting plate 6 is pushed to move inward to clamp the substrate, and a clamping plate 7 is movably sleeved on the front end of the second connecting plate 6. Rollers 8 are movably sleeved on the inner sides of the clamping plate 7. The clamping plate 7 drives the rollers 8 to squeeze and limit the side of the substrate. The outside of the cleaning box 1 is fixedly connected to a bracket 11, and a circular frame 12 is movably sleeved on the inner side of the bracket 11. The back of the cleaning box 1 is fixedly connected to the bracket 11. A circular frame 12 is movably sleeved on the inner side of the bracket 11. The back of the cleaning box 1 is positioned by a positioning plate 2 An extraction box 15 is installed, which can drive the cleaning liquid to be sucked and flushed on the substrate. A first flow pipe 16 and a second flow pipe 17 are fixedly connected to both sides of the extraction box 15. The first flow pipe 16 and the second flow pipe 17 drive the flow of the cleaning liquid. A piston 20 is movably sleeved inside the extraction box 15. A transverse slide 21 is fixedly connected to the upper part of the piston 20. A rotating rod 23 is movably sleeved inside the transverse slide 21. When the rotating rod 23 rotates, it can drive the transverse slide 21 to reciprocate up and down, that is, control the internal circulation of the extraction box 15 and drive the liquid to be sprayed through the second flow pipe 17. A pulley group 24 is installed at the front end of the pulley group 24. A bevel gear 25 is installed at the top of the bevel gear 25. The bevel gear 25 drives the circular frame 12 to rotate synchronously.

[0027] See also Figure 5 The outside of the roller 8 is fixedly connected with a curved spring steel 9, and the outside of the spring steel 9 is fixedly connected with a protective gasket 10. The substrate to be cleaned is clamped between the protective gaskets 10. By clamping one side of the substrate between the two sets of protective gaskets 10, the spring steel 9 drives the protective gasket 10 to be compressed inward according to the shape of the substrate, that is, the protective gasket 10 can apply pressure to the substrate and avoid causing damage to the substrate. At the same time, according to the shape of the substrate, the angle of the roller 8 inside the clamping plate 7 is adjusted, which improves the stability of the substrate during positioning.

[0028] See also Figure 3A cross bar 13 is fixedly connected to the middle of the circular frame 12, and a cleaning device 14 is movably connected to the lower end of the outside of the cross bar 13. A cleaning brush is installed at the lower part of the cleaning device 14. By adjusting the position of the cleaning device 14 outside the cross bar 13, when the circular frame 12 rotates, the extraction box 15 can be driven to perform circular motion with different diameters, that is, the cleaning position of the cleaning brush at the lower end of the extraction box 15 can be regulated.

[0029] See also Figure 3 A filter 3 is installed inside the cleaning box 1 and at the lower end of the cleaning table 2. The filter 3 is inclined at 15 degrees inside the cleaning box 1. The lower end of the cleaning box 1 is filled with cleaning liquid. By filling the cleaning liquid inside the cleaning box 1 and placing the substrate on the upper part of the cleaning table 2 for re-rinsing, the rinsed cleaning liquid is filtered through the cleaning table 2 and refluxed into the inside of the cleaning box 1, thereby improving the utilization rate of the cleaning liquid.

[0030] See also Figure 5 The second connecting plate 6 faces the middle of the cleaning box 1, and the structure of the middle part of the clamping plate 7 is an arc shape that is concave inward. The middle part of the clamping plate 7 is concave inward, that is, when the curved substrate is clamped, the arc space can provide the substrate with movement space to ensure the stability of the substrate during clamping and cleaning. The substrate is limited by the clamping device to avoid position deviation during substrate cleaning. At the same time, the hydraulic rod is started to drive the height of the device to be adjusted, and the threaded rod 5 is rotated to push the clamping plate 7 to move inward. Substrates of different widths can be clamped, and when the substrate is cleaned, the clamping plate 7 can be flipped over to adjust the substrate cleaning surface, thereby further improving the substrate cleaning efficiency.

[0031] See also Figure 4 A one-way valve 26 is installed inside the first flow pipe 16 and the second flow pipe 17, and the two sets of one-way valves 26 have the same direction. The other end of the first flow pipe 16 extends to the interior of the cleaning box 1, and extends to the interior of the cleaning box 1 through the first flow pipe 16. At the same time, the adjustment piston 20 is telescopic. When the piston 20 is moved upward, a negative pressure is formed inside the extraction box 15. At the same time, the one-way valve 26 installed inside the first flow pipe 16 is opened, and the cleaning liquid can be extracted into the interior of the extraction box 15 through the first flow pipe 16. When the piston 20 is pressed downward, the one-way valve 26 installed inside the second flow pipe 17 is opened, that is, the cleaning liquid can be discharged through the second flow pipe 17.

[0032] See also Figure 2, the other end of the second circulation pipe 17 is fixedly connected to a water storage tank 18. The outer part of the water storage tank 18 is fixedly connected with flushing nozzles 19 at equal intervals. The end part of the flushing nozzle 19 is installed above the cleaning table 2, and the flushing nozzles 19 are arranged at equal intervals above the cleaning table 2. A piston 20 is installed at the other end of the second circulation pipe 17. The piston 20 drives the concentrated storage of the cleaning liquid. At the same time, the flushing nozzles 19 are arranged above the cleaning table 2, and the flushing nozzles 19 are used to evenly drive the cleaning spray to the upper part of the cleaning table 2. At the same time, the cleaning liquid can be transported to the surface of the substrate. Thus, the cleaning liquid can wash the substrate.

[0033] Please refer to Figure 6 , a transverse chute is provided inside the transverse slide bar 21. The rotating rod 23 is in a U shape. The middle part of the rotating rod 23 is sleeved inside the transverse chute. A motor is installed at the rear end of the rotating rod 23. By starting the motor, the motor controls the rotation of the rotating rod 23. The middle part of the rotating rod 23 is movably sleeved inside the transverse slide bar 21. When the middle part of the rotating rod 23 moves upward, the rotating rod 23 can drive the piston 20 to adjust the height inside the cleaning tank 1. Thus, as the rotating rod 23 rotates, the piston 20 can be cyclically driven to reciprocate inside the cleaning tank 1, thereby improving the function of redrawing the cleaning liquid.

[0034] Please refer to Figure 3 , the pulley group 24 includes a belt and pulleys. At the same time, one end of the helical gear 25 is fixedly connected to the belt. The helical gear 25 is meshed with the side surface of the circular frame 12. A pulley group 24 is installed at the front end of the rotating rod 23. The belt and pulleys are used to drive the helical gear 25 to rotate. At the same time, the helical gear 25 meshes with the circular frame 12. That is, the force generated by the rotation of the rotating rod 23 is used to synchronously drive the circular frame 12 to rotate above the cleaning tank 1, improving the resource utilization rate, and at the same time making the redrawing of the cleaning liquid and the movement of the brush synchronize.

[0035] Working principle: When in use, the substrate to be cleaned is clamped and installed on the inner side of the roller 8, and the second connecting plate 6 is rotated to push the clamping plate 7 to move inward, so that the substrate can be clamped and limited, and under the rolling action of the roller 8, it can move on the side of the substrate, while ensuring that the substrate is not damaged during clamping. At the same time, the motor installed at the rear end of the rotating rod 23 is started, and the motor uses the horizontal slide bar 21 to drive the piston 20 to move up and down inside the extraction box 15, that is, the extraction box 15 uses the first flow pipe 16 to extract the cleaning liquid, and then transports it to the upper part of the cleaning table 2 through the flushing nozzle 19 to rinse the substrate. At the same time, the rotating rod 23 drives the bevel gear 25 to rotate, and the bevel gear 25 drives the circular frame 12 to rotate, adjusting the position of the cleaning device 14 outside the cross bar 13, and adjusting the moving trajectory of the bevel gear 25. The bevel gear 25 is telescopically adjusted, that is, the bevel gear 25 can automatically recirculate the upper surface of the substrate in a circular shape, thereby improving the flushing efficiency, and after the cleaning liquid flows back to the interior of the cleaning box 1, the flushing liquid can be recycled.
