Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a single-cell battery separator bonding and winding mechanism. Background Technology

[0002] A single battery cell is the basic unit for converting chemical energy into electrical energy. It consists of a positive electrode, a negative electrode, a separator, an electrolyte, a battery case, a battery cover, and terminals. The separator prevents the active material from falling off the plates and prevents the plates from deforming, thus extending the battery's lifespan. When the battery is being processed, a winding mechanism is used to bond and wind up the battery separator to facilitate subsequent battery processing.

[0003] Traditional single-cell separator bonding and winding mechanisms are inconvenient to install and disassemble before and after winding, requiring a lot of manual time and thus affecting work efficiency. Furthermore, it is not convenient to compact the separator during the winding process, which may lead to the separator peeling off. In view of this, a single-cell separator bonding and winding mechanism is provided to overcome the above defects. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-cell battery separator bonding and winding mechanism.

A second spring is sleeved on the fixed rod, and the second spring is fixedly connected to the fixed rod. The second spring is rotatably connected to the inner side of both ends of the extrusion rollers through a washer. Through the second spring, the extrusion rollers can be held between the driving plates.

[0008] As a further description of the above technical solution: a connecting block is fixedly connected to the end of the fixed rod away from the extrusion roller, the connecting block is slidably connected to the inner side of the driving plate, a third spring is fixedly connected to one end of the connecting block, and the third spring is fixedly connected to the inner side of the driving plate. Through the third spring, the extrusion roller can extrude the partition belt and the partition.

[0009] As a further description of the above technical solution: a first compaction roller is attached to the middle and left side of the driving plate, and a second compaction roller is provided at the bottom of the first compaction roller. The front and rear ends of the first compaction roller and the second compaction roller are slidably connected by connecting rods. The connecting rod on the first compaction roller is rotatably connected to the driving plate, and the connecting rod on the second compaction roller is rotatably connected to the lifting block. Through the first compaction roller and the second compaction roller, the partition belt and the partition can be compacted.

[0010] As a further description of the above technical solution: a first spring is sleeved on the connecting rod, and the first spring is fixedly connected to the connecting rod. The first spring is fixedly connected to the inner sides of the front and rear ends of the first compaction roller and the second compaction roller.

The electric cylinder is fixedly connected to the inner side of the driving plate. Through the first spring, the first compaction roller and the second compaction roller can always be kept between the driving plate.

[0011] The present invention has the following beneficial effects:

[0022] As a further description of the above technical solution: a connecting block 20 is fixedly connected to the end of the fixed rod 11 away from the extrusion roller 5. The connecting block 20 is slidably connected to the inner side of the driving plate 2. A third spring 19 is fixedly connected to one end of the connecting block 20. The third spring 19 is fixedly connected to the inner side of the driving plate 2. Through the third spring 19, the extrusion roller 5 can extrude the partition belt and the partition.

[0025] Working principle:

[0026] When using this invention, the take-up sleeve 6 is first placed between the rotating disks 18. Then, the first driver 8 is controlled to drive the threaded rod 13 to rotate. The threaded rod 13 will move the driving plate 2 through the driving block 7. The driving plate 2 will cooperate with the rotating disk 18 to insert the inserter 15 into the take-up sleeve 6. When the inserter 15 is fully inserted into the take-up sleeve 6, the partition belt can be wound onto the take-up sleeve 6 and the partition belt will pass between the first compaction roller 3 and the second compaction roller 4. At this time, the electric cylinder 17 is controlled to drive the lifting block 16 to rise. After the first compaction roller 3 and the second compaction roller 4 clamp the partition belt, the second driver 9 can be controlled to make the take-up sleeve 6... The partition belt is wound up, and during the winding process, the first compaction roller 3 and the second compaction roller 4 can compact the partition belt to prevent it from being loosely adhered. At the same time, when the partition belt reaches the winding sleeve 6, the third spring 19 and the connecting block 20 can press the partition belt that has reached the winding sleeve 6 to prevent the edges of the partition belt from protruding, which would affect the winding effect. When the driving plate 2 moves, the first compaction roller 3, the second compaction roller 4 and the extrusion roller 5 can always be kept between the driving plate 2 by the first spring 10 and the second spring 12. This makes it convenient to unload the wound winding sleeve 6 and also to compact and prevent it from warping during winding.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
