However, although the existing battery cell rubberizing mechanism can automatically attach the rubberizing paper to the surface of the A-type battery cell and the B-type battery cell, it lacks adaptability to more types of battery cells. In addition, for battery cells of different shapes, sizes and materials, the rubberizing mechanism may need to be adjusted and optimized a lot, which is difficult to ensure stable rubberizing operation of the battery cell. Although the existing device uses the rubberizing paper device to attach the cut rubberizing paper to the battery cell, a large amount of manual participation and adjustment is still required, especially in the aspects of battery cell positioning and rubberizing. This not only increases the production cost, but also reduces the production efficiency. SUMMARY

[0004] The utility model aims at providing a battery cell rubberizing mechanism, which integrates a series of functions such as feeding, rubberizing, feeding, clamping, cutting and attaching in a compact structure, realizing the automatic process of battery cell rubberizing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a battery cell rubberizing mechanism for rubberizing the battery cell, comprising a feeding device main body for transmitting the battery cell and a rubberizing device for pulling the rubber film.

[0017] Compared with the prior art, the electric core rubber pasting mechanism has the following beneficial effects:

[0018] 1. The battery cell gluing mechanism realizes the automation process of battery cell gluing by integrating a series of functions such as feeding, pulling glue, feeding, clamping, cutting, and gluing in a compact structure. The operator only needs to start the equipment simply, and the entire gluing process can be completed according to the program control without complex manual operation. In addition, the design of the device makes the connection between each component close and reasonable, which not only facilitates daily operation, but also greatly simplifies the maintenance process. Once a fault occurs, maintenance personnel can quickly locate and repair the problem, thereby ensuring the continuous and stable operation of the equipment. The compact structure, simple operation and convenient maintenance of this device can greatly improve the production efficiency in the gluing process of the new energy industry.

[0019] 2. The battery cell gluing mechanism automatically exchanges the used glue disc with the new glue disc on the module through the glue disc exchange mechanical arm after the glue film is used up. During this process, the equipment does not need to stop, thereby avoiding the time wasted by personnel exchanging the glue disc. At the same time, after the empty glue disc is placed on the module, the module will automatically move to the safety area and wait for manual replacement of the glue disc. After replacement, only the reset button needs to be started, and the glue disc can re-enter the gluing area and wait for use. The design of the equipment without stopping the glue disc exchange not only improves the production efficiency, but also reduces the production interruption and quality problems that may be caused by glue replacement.

[0034] Further, when the second feeding device 312 is started, the mounting frame 313 can be driven to be in a moving state, and the vacuum suction nozzle 322 is in abutment with the glue film. It can be ensured that the glue film can be effectively adsorbed and transmitted to the battery cell 11, which provides a basis for subsequent gluing operation.
