[0002] The power battery module assembly production line connects multiple battery cells in series and parallel to realize battery pack units with different voltages and powers, providing the basic unit battery pack for the power battery pack. In the production and processing of power battery modules, battery cell testing and module assembly are required. Among them, battery cell testing mainly distinguishes good and bad products by measuring the battery cell OCV voltage, and the module assembly line assembles the battery cells and other parts into modules, and welds some parts (mainly bus bars and collection lines). The bus bars and collection lines need to be welded on both sides of the battery module.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figures 1 to 6A double-station cross-type power battery module busbar welding device comprises: a welding frame 1, a pair of positioning frames 2 are arranged below the welding frame 1, and a conveyor belt for conveying the power battery busbar is arranged below each positioning frame 2, a transverse module 1 11 is installed on the welding frame 1, and a transverse module 2 12 is installed on the transverse module 1 11; a welding mechanism 4 is installed on the transverse module 2 12, and is used to weld the busbar of the power battery module; a grinding mechanism 5 is installed on the welding mechanism 4, and is used to grind the weld scar at the welding position of the busbar. In this embodiment, the transverse module 1 11 and the transverse module 2 12 are existing mature technologies. By setting the cooperation of the transverse module 1 11 and the transverse module 2 12, the forward, backward, left and right movement of the welding mechanism 4 can be realized, so as to facilitate the welding work at different positions of the busbar.

[0026] The working principle of the utility model: when in use, the bus is conveyed to the bottom of the welding frame 1 by the conveyor belt, and then the position of the welding mechanism 4 is adjusted by the transverse movement module 11 and the transverse movement module 2 12. Then, the bus is welded by the welding mechanism 4. After the welding is completed, the welding scar can be polished by the polishing mechanism 5. No subsequent manual processing is required, which can effectively improve the processing efficiency of the bus, thereby better meeting the use requirements.

[0027] As a further solution, the welding mechanism 4 includes a lifting module 13 installed on the transverse module 12, a welding seat 41 is installed on the lifting module 13, a welding gun 42 is installed at the lower end of the welding seat 41, and a pair of exhaust pipes 43 are also installed at the lower end of the welding seat 41 corresponding to the welding gun 42. In this embodiment, the lifting module 13 and the welding gun 42 are both existing mature technologies, and an exhaust pump is installed on the exhaust pipe 43 to facilitate the removal of waste smoke generated by welding.

[0028] The working principle of the welding mechanism 4 is: during welding, the welding seat 41 is driven downward by the lifting module 13, so that the welding gun 42 is close to the welding position, and then the welding position of the bus can be welded by the welding gun 42. The welding smoke generated during welding is sucked away through the exhaust pipe 43, which is convenient for centralized treatment.

[0029] As a further solution, the grinding mechanism 5 includes a grinding frame 51 installed on the left side of the lifting module 13, and a grinding electric push rod 52 is installed on the grinding frame 51.

A driving component for driving the grinding rod 1 53 and the grinding rod 2 55 to rotate is also installed on the grinding lifting seat;

[0030] The driving assembly includes a grinding motor 54 mounted on a grinding lifting seat, a grinding pulley 3 551 is mounted on the output end of the grinding motor 54, a grinding pulley 4 552 is mounted on the grinding rod 2 55 at a position corresponding to the grinding pulley 3 551, and a grinding belt 2 553 is sleeved between the grinding pulley 3 551 and the grinding pulley 4 552;

[0031] A grinding pulley 1 531 is also installed on the grinding rod 2 55, a grinding pulley 2 532 is installed at a corresponding position on the grinding rod 1 53, and a grinding belt 1 533 is sleeved between the grinding pulley 1 531 and the grinding pulley 2 532. In this embodiment, a dust removal pipe 23 is also installed on the positioning frame 2, and the end of the dust removal pipe 23 is connected to an external dust collection component (the dust collection component is an existing mature technology).

[0032] The working principle of the grinding mechanism 5 is as follows: when the conveyor belt transports the bus of the power battery module to the position of the dust removal pipe 23, the grinding mechanism 5 is moved to the corresponding position through the transverse movement module 11 and the transverse movement module 2 12, and then the grinding motor 54 is started, and the grinding motor 54 drives the grinding pulley 3 551 to rotate, and the grinding belt 2 553 cooperates with the grinding pulley 4 552 and the grinding pulley 3 551 to drive the grinding rod 2 55 to rotate, and then, the grinding belt belt 1 533 cooperates with the grinding pulley 1 531 and the grinding pulley 2 532 to realize the rotation of the grinding rod 1 53, and then, the grinding electric push rod 52 pushes the grinding lifting seat downward, so that the grinding rod 1 53 and the grinding rod 2 55 are close to the welding scar position, and the welding scar can be ground. The operation is simple, and the dust generated by the grinding can be sucked out through the dust removal pipe 23, which can effectively reduce the pollution to the workshop, and no subsequent manual grinding is required, which can better meet the use requirements.

In this embodiment, the distance measuring module 37, the moving module 1 21 and the moving module 2 22 are existing mature technologies, a CCD camera is also arranged below the distance measuring module 37, and a plurality of through holes are distributed on the positioning pressure plate 33.

[0034] The working principle of the positioning mechanism 3 is: the positioning mechanism 3 is driven to move by the moving module 1 21 cooperating with the moving module 2 22. When the CCD camera can detect the welding position of the bus, it stops moving. Then, the positioning electric push rod 32 extends to push the positioning pressure plate 33 downward, thereby pressing the bus so that its welding position is located below the through hole. Then the distance measuring module 37 measures the distance between the welding mechanism 4 and the welding position, which is convenient for controlling the welding mechanism 4 to move to the welding position of the bus and facilitates the welding work; the adjusting mounting seat 36 is driven to move by adjusting the electric push rod 35, so that the CCD camera moves to another welding position, and then the distance is measured by the distance measuring module 37, so as to facilitate the control of the welding mechanism 4 to move to another welding position, thereby completing the welding work of the bus.
