Description

Technical Field

[0001] This utility model belongs to the technical field of light guide plate production equipment, and more specifically relates to a cleaning device for light guide plates. Background Technology

[0002] During the manufacturing process, dust and dirt may remain on the surface of the light guide plate, requiring cleaning and drying. For example, patent CN113731905A discloses a cleaning and drying device for processing light guide plates. When cleaning the top and bottom surfaces of the light guide plate, it uses a corresponding adsorption mechanism to adsorb the light guide plate before cleaning the other side. However, it does not clean the four sides of the light guide plate. Although the light guide plate is a relatively thin sheet, its sides will also have dust and dirt. Since the sides are generally equipped with linear lights to allow light to enter and reflective sheets to reflect light, cleaning the sides is also particularly important. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cleaning device for light guide plates, which cleans the sides of the light guide plates and ensures that the sides of the light guide plates are clean and free of contamination.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for a light guide plate, comprising a cleaning chamber, wherein a plurality of conveying rollers are arranged inside the cleaning chamber, cleaning pipes are arranged on both sides of the cleaning chamber, a plurality of cleaning nozzles are arranged on the cleaning pipes, and a liftable and rotatable suction cup is arranged on the top of the cleaning chamber, wherein the suction cup is connected to a negative pressure generator.

[0005] Furthermore, a lifting cylinder is connected to the suction cup, and a rotating mechanism is provided between the lifting cylinder and the cleaning chamber.

[0006] Furthermore, the rotating mechanism includes a base, a rotating shaft, and a drive motor. The lifting cylinder is located on the base, the base is connected to the rotating shaft, the rotating shaft is rotatably connected to the top of the cleaning chamber, and the main shaft of the drive motor is connected to the rotating shaft.

[0007] Furthermore, a vertical swing mechanism is provided between the cleaning pipe and the cleaning chamber. The cleaning pipe is hinged to the inner wall of the cleaning chamber. The vertical swing mechanism includes a micro motor, an eccentric rod, and a swing rod. The eccentric rod is connected to the main shaft of the micro motor, the eccentric rod is hinged to the swing rod, and the swing rod is hinged to the cleaning pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: when the conveying roller transports the light guide plate to the area directly below the suction cup, the suction cup descends and contacts the light guide plate, adsorbs the light guide plate under negative pressure, and then lifts the light guide plate to the same horizontal height as the cleaning tube. Then, the cleaning nozzle of the cleaning tube rinses the side of the light guide plate. After rinsing, the suction cup rotates 90 degrees so that the other two sides of the light guide plate are aligned with the cleaning nozzles for another cleaning. After cleaning, the suction cup places the light guide plate back on the conveying roller, thus cleaning the sides of the light guide plate and ensuring that the sides of the light guide plate are clean and free of contamination.

[0014] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0015] A cleaning device for a light guide plate includes a cleaning chamber 1, a plurality of conveying rollers 2 inside the cleaning chamber 1, cleaning pipes 3 on both sides of the cleaning chamber 1, a plurality of cleaning nozzles 4 on the cleaning pipes 3, and a liftable and rotatable suction cup 5 on the top of the cleaning chamber 1, the suction cup 5 being connected to a negative pressure generator.

[0016] like Figure 1 As shown, when the conveyor roller 2 transports the light guide plate to directly below the suction cup 5, the suction cup 5 descends to contact the light guide plate, and lifts the light guide plate to the same horizontal height as the cleaning tube 3 after negative pressure adsorption. Then, the cleaning nozzle 4 of the cleaning tube 3 rinses the side of the light guide plate. After rinsing, the suction cup 5 rotates 90 degrees so that the other two sides of the light guide plate are aligned with the cleaning nozzle 4, and then performs a second cleaning. After cleaning, the suction cup 5 places the light guide plate back on the conveyor roller 2 to achieve the cleaning of the side of the light guide plate.

[0017] Specifically, the cleaning chamber 1 is also equipped with a mechanism for cleaning the upper and lower surfaces of the light guide plate. For the specific structure, please refer to the cleaning and drying equipment for light guide plate processing disclosed in CN113731905A.

[0018] Specifically, the cleaning of the sides of the light guide plate can be placed in front of or behind the upper and lower surface cleaning mechanism.
