Description

Technical Field

[0001] This utility model relates to the field of glass substrate technology, and in particular to a glass substrate cleaning device. Background Technology

[0002] The production of LCD glass substrates involves multiple processes, with cleaning being a crucial step. Cleaning typically employs roller brushes or brush belts. However, after prolonged use, impurities easily accumulate on the surface of roller brushes; failure to replace them promptly will negatively impact the cleaning effectiveness.

[0003] Chinese utility model patent CN219985676U discloses a glass substrate cleaning device. This device features a cleaning structure. Activating a first servo motor drives a cleaning roller to rotate, cleaning the surface of the glass substrate it contacts. Activating a second servo motor drives a threaded rod to rotate, which in turn moves a movable block to one end outside the threaded rod. This movement causes a limiting block to move to one end outside the limiting rod. The limiting block and the movable block together move the cleaning roller to one end, allowing the cleaning roller to clean different areas of the glass substrate, resulting in more comprehensive cleaning and improved glass substrate cleaning.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: After cleaning a glass substrate, the device needs to remove the cleaned glass substrate and replace it with a new one, which is quite troublesome. In addition, since glass substrates of different sizes have different thicknesses, when cleaning the surface of the glass substrate, it is necessary to adjust the spray position of the nozzle so that the water can spray onto the top of the glass substrate and ensure that the glass substrate is completely covered by the water flow. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a glass substrate cleaning device.

[0006] This utility model is achieved using the following technical solution: a glass substrate cleaning device, including a base plate, a cleaning tank fixedly connected to the top of the base plate, a water collection box installed at the bottom of the cleaning tank, a limit frame slidably connected to the top of the water collection box, a cylinder fixedly connected to the right side of the limit frame, a pump installed on the top of the cleaning tank, a return pipe connected to the input end of the pump, one end of the return pipe connected to one end of the water collection box, a cleaning assembly installed on the left side of the cleaning tank, and two sets of symmetrically arranged brushing assemblies installed inside the cleaning tank.

[0007] The cleaning assembly includes two water pipes and a bidirectional lead screw. The output end of the pump is connected to a U-shaped pipe, and the two ends of the U-shaped pipe are respectively connected to the top of the water pipe. Spray nozzles are connected to the bottom of the water pipe at equal intervals. A deflection gear is sleeved on the outside of the water pipe. A limit groove plate is installed on the left side of the cleaning tank. One end of the bidirectional lead screw is rotatably connected to the inner wall of the limit groove plate. Two symmetrically arranged threaded blocks are threaded to the outside of the bidirectional lead screw. Two movable toothed plates are fixedly connected to the bottom of the threaded blocks. The surface of the movable toothed plates meshes with the surface of the deflection gear.

[0008] The brushing assembly includes two vertical plates, the surfaces of which are fixedly connected to the inner wall of the cleaning tank. A guide rod and a threaded rod are installed between the two vertical plates. A moving motor is fixedly connected to one end of the threaded rod, and a moving plate is threadedly connected to the outer side of the threaded rod. The guide rod is slidably disposed inside the moving plate. Two electric telescopic rods are fixedly connected to the surface of the moving plate. A U-shaped frame is fixedly connected to one end of the electric telescopic rod. A cleaning roller is installed inside the U-shaped frame, and a rotary motor is fixedly connected to one end of the cleaning roller.

[0009] As a further improvement to the above solution, the limiting frame is composed of two U-shaped plates, and spring rods are fixedly connected at equal intervals on both sides of the inner wall of the U-shaped plates. One end of the spring rod is fixedly connected to a pressing plate, which facilitates the limiting and fixing of the glass substrate.

[0010] As a further improvement to the above solution, the bottom of the limiting frame is fixedly connected to two sliding plates, and the top of the bottom plate is provided with a sliding groove for the sliding plates to move, ensuring the normal movement of the limiting frame.

[0011] As a further improvement to the above solution, a connecting plate is fixedly connected to the right side of the cylinder, and a support plate is sleeved on the outside of the cylinder. The bottom of both the connecting plate and the support plate are fixedly connected to the top of the base plate, ensuring the normal operation of the cylinder.

[0012] As a further improvement to the above solution, two limiting bearings are installed on the outside of the water pipe, and two limiting plates are fixedly connected to the top of the inner wall of the cleaning tank. The limiting bearings are installed inside the limiting plates to ensure the normal operation of the water pipe.

[0013] As a further improvement to the above solution, a protective cover is installed on the outside of the rotary motor, and the bottom of the protective cover is fixedly connected to the top of the U-shaped frame. A mounting block is installed on the bottom of the mobile motor, and the surface of the mounting block is fixedly connected to the surface of the left vertical plate, ensuring the normal operation of the rotary motor and the mobile motor.

[0014] As a further improvement to the above solution, a straight groove is provided in the middle of the water collection box, and the limiting frame is slidably set inside the straight groove. Two filter screens are installed on the top of the water collection box to ensure the normal movement of the limiting frame and facilitate the collection of water flow.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a cleaning component, places the glass substrate on a limiting frame. According to the thickness of the glass substrate, the bidirectional lead screw is rotated, causing two threaded blocks to move in opposite directions on the bidirectional lead screw. This, in turn, causes two moving toothed plates to move in opposite directions, causing the deflection gear to deflect. This, in turn, causes the water pipe carrying the nozzle to deflect, allowing the nozzle to spray onto the top of the glass substrate surface. This ensures that the water flow covers the entire glass substrate, guaranteeing that the entire glass substrate can be cleaned. This allows the device to adapt to glass substrates of different thicknesses, improving the device's adaptability.

[0017] 2. This utility model, by setting up a brushing component, places the glass substrate on the limiting frame, then activates the cylinder to move the glass substrate into the cleaning tank. During this process, a rotary motor is activated to rotate the cleaning roller, which moves along the surface of the glass substrate while rotating, thereby achieving a comprehensive cleaning of the glass substrate surface. During the cleaning process, a new glass substrate is placed on another U-shaped plate on the limiting frame. After cleaning is completed, the cylinder is activated to move the limiting frame with the new glass substrate into the cleaning tank. Then, the cleaned glass substrate is removed and replaced with a new one, enabling the device to continuously clean the glass substrate and improving the continuity of the device.
