Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-3 As shown, the utility model provides a cleaning device for processing solar cell sheets, comprising a cleaning box 1, in which symmetrically distributed cleaning rollers 11 are rotatably arranged, a clamping member 12 is arranged between the two cleaning rollers 11, the clamping member 12 is U-shaped, and grooves 18 are provided on opposite sides of the two ends of the clamping member 12, a first bevel gear 13 is rotatably arranged on the upper surface of the cleaning box 1, a positioning rod 14 is fixedly arranged on the first bevel gear 13, a first connecting member 15 is fixedly arranged on one end of the positioning rod 14 away from the first bevel gear 13, a second connecting member 16 is rotatably arranged on the upper surface of one end of the first connecting member 15 away from the positioning rod 14, a connecting rod 17 is rotatably arranged on the lower surface of the second connecting member 16 away from the first connecting member 15, one end of the connecting rod 17 close to the cleaning rollers 11 is fixedly arranged on the clamping member 12, a feeding plate 6 is arranged on one end of the cleaning box 1 away from the first bevel gear 13, and one end of the feeding plate 6 is rotatably arranged on the cleaning box 1.

[0019] A rotating rod 2 is rotatably provided at one end of the cleaning box 1 close to the first bevel gear 13, a second bevel gear 21 is fixedly provided at one end of the rotating rod 2 close to the first bevel gear 13, the second bevel gear 21 and the first bevel gear 13 are meshed with each other, a large gear 22 is fixedly provided at one end of the rotating rod 2 away from the first bevel gear 13, a small gear 23 is rotatably provided on one side of the cleaning box 1 close to the large gear 22, the large gear 22 and the small gear 23 are meshed with each other, and a belt 24 is provided for rotating together between a cleaning roller 11 and the small gear 23. The small gear 23 can be driven to rotate by the belt 24. Since the small gear 23 and the large gear 22 are meshed with each other, the large gear 22 will be driven to rotate when the small gear 23 rotates. When the large gear 22 rotates, the second bevel gear 21 is driven to rotate through the rotating rod 2. Since the second bevel gear 21 and the first bevel gear 13 are meshed with each other, the first bevel gear 13 will be driven to rotate when the second bevel gear 21 rotates. When the first bevel gear 13 rotates, the first connecting member 15 will be driven to rotate. Since the second connecting member 16 is rotatably arranged on the upper surface of the first connecting member 15, the second connecting member 16 will move with the first connecting member 15 when the first connecting member 15 rotates. Since the connecting rod 17 is rotatably arranged on the lower surface of the second connecting member 16 and is penetrated in the cleaning box 1, when the second connecting member 16 moves, the connecting rod 17 will drive the clamping member 12 to perform a cyclic reciprocating motion.

[0020] One end of the two cleaning rollers 11 away from the belt 24 is fixedly provided with a gear 25, and the two gears 25 mesh with each other. Through the meshing of the two gears 25, when one of the gears 25 rotates, the other gear 25 rotates relative to it, thereby driving the cleaning rollers 11 to rotate relative to achieve the purpose of cleaning.

[0021] A motor 26 is fixedly arranged at one end of a cleaning roller 11 away from the gear 25, and the motor 26 is fixedly arranged on the side of the cleaning box 1. The motor 26 can provide driving force for one cleaning roller 11, and since two mutually meshing gears 25 are fixedly arranged at one end of the two cleaning rollers 11 away from the motor 26, when one cleaning roller 11 rotates, the other will rotate with it, thereby driving the belt 24 to rotate and drive the pinion 23.

[0022] A symmetrically distributed slide groove 3 is provided at one end of the clamping member 12 away from the connecting rod 17. A limit plate 31 is slidably arranged in the two slide grooves 3. A handle 32 is fixedly arranged on the side of the limit plate 31 away from the clamping member 12. The limit plate 31 can slide up and down through the slide groove 3. When the limit plate 31 is located at the bottom of the slide groove 3, the battery cell in the clamping member 12 can be limited to prevent the battery cell from falling off from the clamping member 12 during the cleaning process. The handle 32 can facilitate the staff to move the limit plate 31.

[0023] A water pump 4 is fixedly provided on one side of the cleaning box 1 close to the gear 25, a first delivery pipe 41 is fixedly provided on the lower surface of the water pump 4, an end of the first delivery pipe 41 away from the water pump 4 is fixedly provided inside the cleaning box 1, a second delivery pipe 42 is fixedly provided on the upper surface of the water pump 4, an end of the second delivery pipe 42 away from the water pump 4 is fixedly provided on the inner wall of the cleaning box 1, a plurality of nozzles 43 are fixedly provided on the second delivery pipe 42, and a filter 5 is fixedly provided inside the cleaning box 1. The cleaning liquid in the cleaning box 1 can be pumped into the second delivery pipe 42 by the water pump 4, sprayed onto the battery cells from the nozzles 43, and the used cleaning liquid will flow into the bottom of the cleaning box 1 again after being filtered by the filter 5, so as to achieve the purpose of reusing the cleaning liquid.

[0024] Working principle: When the battery cell needs to be cleaned, the staff needs to open the feed plate 6 first, then move the limit plate 31 upwards through the handle 32, and then put the battery cell to be cleaned into the groove 18, and then move the limit plate 31 to the bottom of the slide 3 to limit the battery cell, and then start the device. The cleaning liquid at the bottom of the cleaning box 1 will be pumped into the second delivery pipe 42 through the water pump 4 and sprayed onto the battery cell from the nozzle 43. At the same time, the cleaning roller 11 rotates under the drive of the motor 26. Since the two gears 25 are meshed with each other, the two cleaning rollers 11 will rotate relative to each other. When the cleaning roller 11 rotates, it will drive the belt 24 to rotate. The rotation of the belt 24 will drive the small gear 23. When the small gear 23 rotates, the large gear 22 meshed with it will rotate accordingly. When the large gear 22 rotates, it will drive the second bevel gear 21 and the first bevel gear 13 meshing therewith to rotate. When the first bevel gear 13 rotates, it will drive the first connecting member 15 to rotate. Since the second connecting member 16 is rotatably arranged on the upper surface of the first connecting member 15, when the first connecting member 15 rotates, the second connecting member 16 will move with the first connecting member 15. Since the connecting rod 17 is rotatably arranged on the lower surface of the second connecting member 16 and is penetrated in the cleaning box 1, when the second connecting member 16 moves, the connecting rod 17 will drive the clamping member 12 to perform a cyclic reciprocating motion. The battery cell can be thoroughly cleaned by the above method; the used cleaning liquid will be filtered through the filter net 5 and then re-enter the bottom of the cleaning box 1, so as to achieve the purpose of reuse and prevent waste.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
