[0002] Battery cell packaging refers to using a battery soft-pack aluminum plastic film to package a lithium-ion battery. The battery soft-pack aluminum plastic film, abbreviated as aluminum plastic film, is a composite soft packaging shell material for packaging lithium-ion batteries, including hot air welding the front and side of the aluminum plastic film containing the lithium battery cell. Generally, there are the following two steps: First, in order to place the battery roll core in the groove, the aluminum plastic film is first punched into a groove with a corresponding depth; Second, when hot air welding the aluminum plastic film, the sealing position needs to be 0.05 - 0.5 MM away from the side of the roll core.

[0003] In the existing battery cell packaging equipment, due to the relatively large size of the battery cell, the machine production capacity is restricted by the mechanism, and thus the battery production is only 15 PPM (PPM full name is Piece Per Minutes, mainly used to measure the efficiency and production capacity of the battery production line). The machine occupies a large area, the equipment procurement cost is high, the maintainability is poor, and at the same time, the changeover cost is extremely high. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a double-station automatic battery packaging machine in view of the current situation of the existing technology.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

In the utility model, the core mechanisms of the equipment such as punching and molding, packaging, and the battery cell logistics mode are newly designed, so that the equipment structure is compact and occupies a small area. While reducing costs, the equipment production capacity is increased to 25PPM. The previous packaging equipment can only package one battery cell at a time due to the size of the battery cell, the overall layout of the machine, and the limitations of the mechanism. Through the new design and layout of the packaging machine equipment, the equipment can carry two sheets of film at a time and can package two battery cells at a time for circulation, which greatly improves the integration and production efficiency of the machine, and at the same time greatly reduces the cost and time of changeover and maintenance.

[0044] Specifically, the mold adopts a one-out-two form. The punching is driven by two electric cylinders and a servo motor, and the film is punched out simultaneously on both the left and right sides. The film pressing is driven by a lead screw and a servo motor; after the film pressing lead screw moves upward to press the film first, the two punching servo electric cylinders move downward to punch the film.

This mechanism uses one punching mechanism 11 to simultaneously achieve the punching and forming of two films;

[0045] The film top cutting mechanism 12 includes a top cutting tool 1201 and a variable pitch lead screw module 1202;

[0046] Further, the two films are transported to the top cutting position by the film discharging manipulator.

After positioning, the shell inserting robot transports them to the tab forming platform to fold the tabs. If a battery cell is NG, it is placed in the blank collecting mechanism, and the remaining one battery cell is placed on the buffer platform for temporary storage and flows into the next station instead of the next wave of NG battery cells; when the blank collecting mechanism is full, the belt module will send out the blanks for easy removal by personnel; the entire hot pressing assembly 1403 has a compact layout, and the hot pressing uses an electric cylinder and servo drive, which can effectively control the hot pressing movement and accuracy.

The top sealing adopts an independent packaging mechanism for each product, and the top sealing of two products can be carried out synchronously; the manipulator adsorbs and picks up the battery cells through vacuum suction cups, and changes the distance between the battery cells through a variable-distance cylinder. After the corner sealing handling manipulator transports two battery cells to the corner sealing support platform, the corner sealing assembly starts to perform corner sealing under the action of the corner sealing cylinder. The adjustment guide rail below the corner sealing can adapt to battery cells of different sizes, and alternately transports the battery cells on the corner sealing support platform to the two platforms of the side sealing rearrangement mechanism, so as to rearrange the battery cells; then it is transported to the next station by the side sealing rearrangement mechanism; the side sealing handling manipulator is designed for triple handling, and the three movers act simultaneously. The first mover transports the two side-sealed and rearranged battery cells to the side sealing support platform, the second mover transports the two side-sealed battery cells to the side cutting platform, and the third mover transports the two side-cut battery cells to the insulation test platform; the battery cells are placed on the side sealing support platform by the side sealing handling manipulator, and the motor drives the lead screw to move downward to package the battery cells. The side sealing adopts a single station to package a single battery cell, and the packaging forming parameters can be accurately controlled. There are two side sealing stations in total, and the side sealing of two products can be carried out synchronously; after the battery cells are transported to the side cutting platform by the side cutting handling manipulator, the side cutting platform changes the distance through a slide cylinder. After the distance between the two battery cells is changed, the side cutting cylinder drives the side cutting tool to move downward for side cutting. The cutting film position is adjusted by the motor and the lead screw, and the forming parameters of the battery cells can be accurately controlled. There are two side cutting stations in total, and the side cutting of two battery cells can be carried out simultaneously.

[0055] In summary, the device has a high degree of automation, a simple and precise working process, and can meet various requirements for cell packaging. Through the unwinding and dust removal mechanism 7, film pulling and transfer mechanism 9, pit punching mechanism 11, and sheet film top cutting mechanism 12 in the aluminum-plastic film forming component 2, the automated pit punching and forming of the aluminum-plastic film is completed. The formed sheet film is transported by the shell loading manipulator in the cell loading component 4 to the double-station fixture mechanism 16 for shell loading. The tab ears of two cells are simultaneously shaped and hot-pressed by the loading mechanism 13 and the hot pressing and shaping mechanism 14. Then, the hot-pressed cells are transported by the shell loading manipulator mechanism 15 to the double-station fixture mechanism 16 for shell loading. The cell packaging is completed by the top sealing mechanism 17, corner sealing mechanism 18, side sealing mechanism 20, and side cutting mechanism 21 in the packaging component 5. The appearance of the packaged cells is inspected by the insulation testing mechanism 24, CCD inspection mechanism 26, and thickness measuring mechanism 29 in the inspection component 6, and the cells are marked and scanned by the inkjet coding mechanism 28. The good products and defective products are separately unloaded by the unloading and sorting mechanism 30. Compared with the existing equipment, the production capacity of this equipment can be increased by 100%. Due to the limitations of the cell size, the overall machine layout, and the mechanism, the previous packaging equipment could only package one cell at a time. Through the adjustment of the mechanism and the process, the equipment is compact in structure and occupies a small area. When packaging, the equipment can not only package two cells at a time but also greatly improve the machine production capacity.
