Description

Technical Field

[0001] This utility model relates to the technical field of battery processing, specifically to a sealing device for new energy battery production. Background Technology

[0002] Battery sealing equipment is an indispensable piece of equipment in the battery production process. It is mainly used to encapsulate new energy batteries to protect the internal chemical materials and structure of the battery, while improving the stability and safety of the battery. With the rapid development of the new energy industry and the continuous progress of battery technology, the importance of new energy battery sealing equipment in the battery production process is becoming increasingly prominent. In the future, as the requirements for battery performance and safety continue to increase, the technical level and application scope of new energy battery sealing equipment will continue to expand. New energy battery sealing equipment is one of the important pieces of equipment in the battery production process, and it plays a vital role in improving the stability and safety of batteries.

[0003] A search revealed that Chinese Patent Publication No. CN113381035A discloses a sealing device for new energy battery manufacturing. While this invention patent solves the problem that current new energy battery production sealing devices require separate operations on the front and back of the battery during sealing, resulting in low production efficiency, increased labor costs, and misalignment of the front and back during sealing, seriously affecting the sealing quality, this invention patent has the following problems: 1. Since plastic films are mostly in long rolls, they need to be cut after sealing the battery. This patent uses a cylinder to push the upper cutting block downwards to separate the sealed battery sheet from the film. During the separation process, the elasticity of the film can easily cause deformation of the sealed film on the battery surface; 2. This application requires workers to place the battery sheet in a designated position and ensure it is aligned correctly. The placement process is not continuous and has low efficiency, thus affecting the sealing speed. Summary of the Invention

The pulley 261 is connected to the pulley 28 on the drive roller 22 through a drive belt 27.

[0025] In addition, the sealing mechanism 3 includes an extrusion roll 31, an extrusion roller 32, a second motor 33, and an electric heating wire 36. Two film rolls 31 are provided and symmetrically arranged on the upper and lower sides of the frame 1. The film rolls 31 are rotatably connected to the support plates on both sides of the frame 1 and the film to be coated is wound on them.

[0028] Detailed implementation methods and principles:

[0029] In use, the film on the film roll 31 is passed under the extrusion roller 32, and the battery cell to be sealed is placed into the battery box 21. The motor 26 is started, and the pulley 261 on the output shaft of the motor 26 drives the pulley 28 and the drive roller 22 to rotate via the drive belt 27. The feed belt 24 on the drive roller 22 rotates, and the pusher 25 on the feed belt 24 passes through the through hole 213 on the battery box 21 to push the bottom battery cell through the discharge port 214 onto the frame 1. Then the feed belt 24 drives the pusher to continue moving until the pusher 25 returns to the initial position, waiting for the next push of the battery cell. This ensures the continuity of the process and has high efficiency, thereby improving the sealing speed. At the same time, the battery cell moves towards the extrusion roller 32. When the battery cell moves towards the next extrusion roller due to inertia, the next pusher 25 pushes the battery cell to the next extrusion roller 32 to push ... When the battery cell moves between the two sets of extrusion rollers 32, motor 2 33 is started. The output shaft of motor 2 33 drives the extrusion rollers 32 to rotate. With the cooperation of pulley 3 34, the two sets of extrusion rollers 32 rotate, thereby pushing the battery cell away from the battery box 21. At the same time, the film adheres to the outer wall of the battery cell. Under the action of electric heating wire 36, the film at one end is tightly attached to the battery cell. Then motor 3 43 is started. The output shaft of motor 3 43 drives the reciprocating screw 41 to rotate. The sliding block 44 and the cutter 46 move along the outer wall of the reciprocating screw 41, thereby cutting the film. The film attached to the surface of the battery cell will not deform. At the same time, the dust pump 56 collects the impurities in the dust cover 51 through pipe 1 52 and enters the collection box 54 through pipe 2 53 for collection and treatment.

[0030] In summary, this application uses the feeding mechanism 2 to automatically feed the battery cells, thereby ensuring the continuity of the sealing process and achieving high efficiency, thus increasing the sealing speed. At the same time, the cutting mechanism 4 uses the cutting blade 46 to cut the film on the coated battery cells, and the electric heating wire 36 heats the film and applies it to the battery cells, ensuring that the film applied to the surface of the battery cells will not deform. Meanwhile, the dust pump 56 adsorbs the impurities generated after cutting inside the dust cover 51, preventing impurities from adhering to the battery cells and causing air bubbles in the coated battery cells.

[0031] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
