[0001] This utility model relates to the field of battery manufacturing technology, specifically a multi-axis linkage anti-oxidation packaging device for lithium battery caps. Background Technology
[0002] The lithium battery cap packaging device is a core piece of equipment in lithium battery manufacturing. It is mainly used for the precision packaging between the battery cap and the casing, which directly affects the battery's sealing performance, safety, and cycle life. With the surge in demand for high-energy-density and long-life lithium batteries in the fields of new energy vehicles, energy storage systems, and consumer electronics, traditional packaging processes are unable to meet the reliability requirements of power batteries under high-current charging and discharging and extreme operating conditions due to insufficient precision, low efficiency, and poor sealing consistency.
[0003] When encapsulating lithium battery caps, fine particles may remain on the cap surface due to processing. These uncleaned particles can increase the risk of short circuits after encapsulation, affecting battery performance. On the other hand, most lithium battery caps lack anti-oxidation capabilities, causing the metal caps to oxidize and corrode over long-term use, thus affecting battery lifespan. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a multi-axis linkage anti-oxidation packaging device for lithium battery caps. Through the cleaning component, the lithium battery cap of the next package can be cleaned to avoid the small particles remaining during processing being packaged together. Through the spraying component, a dense protective film is formed on the lithium battery cap, thereby improving the anti-oxidation ability of the lithium battery cap.

Detailed Implementation
[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1-5 As shown, a multi-axis linkage anti-oxidation packaging device for lithium battery caps includes a worktable 1, a support frame 101 connected to the top of the worktable 1, a conveying feeding mechanism 102 and a conveying discharging mechanism 103 installed on the top of the worktable 1, a pad 202 connected to the top of the worktable 1, and a lithium battery 204 installed on the top of the pad 202. A cleaning component located on the top of the worktable 1 is used to clean the caps of the lithium battery 204 before packaging. The cleaning component includes a conveying block 203, an airbag a 301 and an air outlet 302. A spraying component located on the top of the worktable 1 is used to spray anti-oxidation material onto the caps of the lithium battery 204 before packaging. The spraying component includes an airbag b 503, a spray nozzle 603 and an alumina solution tank 602.
[0021] In this process, the lithium battery 204 is pushed to the bottom of the packaging mechanism by the electric push rod a201 using the conveying block 203, airbag a301, and air outlet 302 in the cleaning component. At the same time, the connecting rod 3 presses the airbag a301 to squeeze out air and clean the cap of the next lithium battery 204. This prevents small particles left over from processing from being packaged together and affecting the battery's performance. Secondly, the airbag b503, nozzle 603, and alumina solution tank 602 in the spraying component compress the airbag b503 while the packaging mechanism 501 is packaging. This causes the alumina solution to be sprayed at the nozzle onto the cap of the next lithium battery 204 to be packaged, forming a dense protective film and thus improving the anti-oxidation capability of the lithium battery 204 cap.
[0022] The workbench 1 is connected to a fixed block a2 at the top, and an electric push rod a201 is installed on the top of the fixed block a2. A conveying block 203 is set on the top of the pad 202. One end of the electric push rod a201 is connected to one side of the conveying block 203. A connecting rod 3 is connected to the outside of the electric push rod a201. An air bag a301 is installed on one side of the conveying and feeding mechanism 102. One end of the connecting rod 3 is connected to one side of the air bag a301. An air outlet 302 is set on one side of the air bag a301. A baffle 4 is connected to the top of the conveying and feeding mechanism 102. A HEPA filter 401 is installed inside the baffle 4.
[0023] During the encapsulation of lithium battery caps, fine particles may remain on the cap surface due to processing. These unremoved particles can increase the risk of short circuits after encapsulation, affecting battery performance. After the feeding mechanism 102 conveys the lithium battery 204 into the conveying block 203, the electric push rod a201 pushes the conveying block 203 along the pad 202, pushing the lithium battery 204 to the encapsulation station between the two clamping blocks 702. Simultaneously, pressure is applied to the airbag a301 through the connecting rod 3. The gas inside the airbag a301 is discharged through the air outlet 302. The discharged airflow cleans the surface of the cap of the next lithium battery 204 to be processed. Since the air outlet 302 faces the baffle 4, the cleaned particles are blown onto the baffle 4 by the gas and then collected by the HEPA filter 401. The cleaned lithium battery 204 continues to be conveyed forward to the pad 202 through the conveying feeding mechanism 102 to wait for pushing.
[0024] The support frame 101 has a hydraulic rod 5 mounted on its top. The bottom of the hydraulic rod 5 is connected to a sealing mechanism 501. A fixing rod 502 is connected to one side of the sealing mechanism 501. An airbag b503 is connected to one end of the fixing rod 502. An air inlet pipe 6 is provided on one side of the airbag b503. An air outlet pipe 601 is connected to the bottom of the airbag b503. Both the air inlet pipe 6 and the air outlet pipe 601 are equipped with one-way valves. A fixing block b604 is connected to the top of the workbench 1. An alumina solution tank 602 is mounted on the top of the fixing block b604. A spray pipe 603 is connected to one side of the alumina solution tank 602. A nozzle is connected to one end of the spray pipe 603. One end of the air outlet pipe 601 extends into the alumina solution tank 602. Two fixing blocks c7 are connected to the top of the workbench 1. An electric push rod b701 is mounted on the top of each of the two fixing blocks c7. A clamping block 702 is connected to one end of the electric push rod b701.
[0025] Most lithium battery caps, due to their lack of anti-oxidation capabilities, suffer from oxidation and corrosion during long-term use, affecting battery life. When the hydraulic rod 5 drives the sealing mechanism 501 to press down and seal the lithium battery 204, the fixing rod 502 moves down synchronously with the sealing mechanism 501 and compresses the airbag b503. After being compressed, the gas inside the airbag b503 is discharged through the one-way valve of the vent pipe 601. By squeezing the gas inside the alumina solution tank 602, the anti-oxidation solution is sprayed out from the nozzle 603 and then sprayed onto the lithium battery 204 cap through the nozzle. Then, the sealing mechanism 501 finishes sealing and moves upward through the hydraulic rod 5, simultaneously driving the fixing rod 502 upward, creating negative pressure inside the airbag b503. Then, air is introduced through the vent pipe 6, allowing the airbag b503 to return to its original state. By forming an anti-oxidation protective layer on the cap, the anti-oxidation capability of the lithium battery cap is improved, extending the life of the lithium battery.
[0026] Working principle:
[0027] During the encapsulation of lithium battery caps, fine particles may remain on the cap surface due to processing. These unremoved particles can increase the risk of short circuits after encapsulation, affecting battery performance. After the feeding mechanism 102 conveys the lithium battery 204 into the conveying block 203, the electric push rod a201 pushes the conveying block 203 along the pad 202, pushing the lithium battery 204 to the encapsulation station between the two clamping blocks 702. Simultaneously, pressure is applied to the airbag a301 through the connecting rod 3. The gas inside the airbag a301 is discharged through the air outlet 302. The discharged airflow cleans the surface of the cap of the next lithium battery 204 to be processed. Since the air outlet 302 faces the baffle 4, the cleaned particles are blown onto the baffle 4 by the gas and then collected by the HEPA filter 401. The cleaned lithium battery 204 continues to be conveyed forward to the pad 202 through the conveying feeding mechanism 102 to wait for pushing.
