Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a pneumatic negative pressure forming cleaning tooling. Background Technique

[0002] During the manufacturing process of new energy batteries, the battery cells are charged by forming equipment to activate the activity of the battery cells. During the continuous charging process, chemical reactions will occur inside the battery cells, generating gas. If these gases cannot be sucked out in time, the battery will bulge due to the internal and external pressure difference, affecting the yield rate and reducing the production capacity. Therefore, a negative pressure system is integrated in the forming equipment. Specifically, a negative pressure forming suction nozzle is equipped for each battery cell, and continuous suction is carried out during the forming process.

[0003] In the prior art, the authorized announcement number is: CN215142525U, and the name is a cleaning tooling for a negative pressure forming suction nozzle of a lithium battery, which can realize the automatic continuous cleaning of the negative pressure forming suction nozzle on the forming equipment without disassembling the suction nozzle. The tooling is light and simple in design, and can replace manual labor to automatically clean thousands of suction nozzles in the forming workshop, greatly reducing the disassembly and assembly time of the suction nozzles and eliminating potential safety hazards of manual disassembly and assembly. In the above patent solution, when the wedge block on the storage position presses the wedge block and the upper wedge block separates from the wedge block, the generated movement drives the cleaning head to rotate and clean the suction nozzle. However, the rotation of the cleaning head in the whole process is divided into two times, one forward rotation and one reverse rotation. Since each extrusion of the wedge block can only trigger one forward movement, when the wedge block separates from the upper wedge block, the reverse movement generated when the rack resets can only complete one reverse rotation. This means that in each cleaning cycle, the rotation times of the cleaning head are only two times. Such limited cleaning times may be insufficient for stubborn electrolyte and cannot achieve thorough cleaning. And in the above patent solution, the electrolyte inside the suction nozzle is cleaned by the cleaning sponge in the cleaning head, but for the residues in the relatively narrow space inside the suction nozzle, the cleaning effect of the sponge is limited.

A motor 217 is fixed to the outer side of the fixing plate 214, and the output shaft end of the motor 217 penetrates through the fixing plate 214 and is fixed to one end of the second rotating rod 215. The length of the pushing block 216 is greater than the distance between the second rotating rod 215 and the first rotating rod 213.

[0030] The cleaning mechanism 2 further includes a rotating cylinder 208 rotatably connected to the inner wall of the mounting plate 1.

A cleaning head 210 is fixedly communicated with the top end of the rotating cylinder 208, and a sponge 211 is arranged on the inner wall of the cleaning head 210.

[0031] By starting the motor 217 to drive the second rotating rod 215 to rotate, the second rotating rod 215 can drive the pushing block 216 to rotate. The end of the pushing block 216 away from the second rotating rod 215 can push the first rotating rod 213 to move, so as to drive the rack 204 to move. The movement of the rack 204 can drive the rotating cylinder 208 to rotate through meshing with the gear 209. The rotating cylinder 208 can drive the cleaning head 210 and the sponge 211 to rotate, so as to clean the electrolyte inside the negative pressure forming nozzle. When the rack 204 moves, the spring 207 will be compressed to generate elastic force.

[0034] By starting the air compressor 5, air can be conveyed into the rotating cylinder 208 through the air pipe 7. The air in the rotating cylinder 208 can be conveyed into the negative-pressure forming suction nozzle. The high-pressure air flow can directly wash the electrolyte inside the negative-pressure forming suction nozzle, effectively removing the accumulated electrolyte residues, crystals and other impurities.

Then start the motor 217. By starting the motor 217, the second rotating rod 215 is driven to rotate. The second rotating rod 215 can drive the push block 216 to rotate. One end of the push block 216 away from the second rotating rod 215 can push the first rotating rod 213 to move, thereby driving the rack 204 to move. The movement of the rack 204 can drive the rotating cylinder 208 to rotate through the meshing with the gear 209. The rotating cylinder 208 can drive the cleaning head 210 and the sponge 211 to rotate, thereby cleaning the electrolyte inside the negative-pressure forming suction nozzle. The movement of the rack 204 will squeeze the spring 207 to generate elastic force. When the push block 216 is away from the first rotating rod 213, the rack 204 will reset under the elastic force of the spring 207, and at the same time, it can also drive the cleaning head 210 and the sponge 211 to clean the electrolyte inside the negative-pressure forming suction nozzle again, forming a reciprocating motion to clean the negative-pressure forming suction nozzle, avoiding the problem of electrolyte residue. At the same time, the air compressor 5 can be started when the sponge 211 is cleaning. By starting the air compressor 5, air can be conveyed into the rotating cylinder 208 through the air pipe 7. The air in the rotating cylinder 208 can be conveyed into the negative-pressure forming suction nozzle. The high-pressure air flow can directly wash the electrolyte inside the negative-pressure forming suction nozzle, effectively removing the accumulated electrolyte residues, crystals and other impurities.
