Compared with traditional batteries, it is thinner, lighter and more flexible, enabling the soft-pack battery to adapt to various shapes and sizes of electronic devices, providing more degrees of freedom for product design. Among them, during the production and processing of soft-pack lithium battery cells, operations such as transfer are required to switch the processing position of the lithium battery cells or perform loading and unloading, etc.

[0004] However, the above device only has simple clamping and handling effects. When processing lithium battery cells, it is often necessary to process both sides of the battery cells respectively. Therefore, it is necessary to flip the lithium battery cells, but the above device cannot achieve the flipping function, and during processing, an additional rotating structure or manual flipping of the lithium battery cells is required.

[0005] Chinese Patent CN118495144A discloses a handling mechanism for soft-pack lithium battery cells with clamping and rotating functions, including a base and a clamping component. It is characterized in that: a cylindrical seat is fixed at the center of the top surface of the base, and two vertical and symmetrical first rotating frames are connected by a first rotating component on both sides above the cylindrical seat; short shafts are rotatably connected to the tops of the two first rotating frames, and a rotating seat is fixedly arranged between the two short shafts. A second rotating component is arranged at the center of the top of the cylindrical seat, and the second rotating component is correspondingly connected to the two short shafts; a horizontal installation groove is arranged in the middle of the rotating seat, and a rotating plate is installed inside the installation groove.

A motor is connected to the rotating end of one of the connecting rods located on the side plate, and the motor is fixed on the side plate; two parallel side plates are symmetrically fixed at the front ends of the third rotating frame, and clamping cylinders are arranged on the side plates. The telescopic ends of the clamping cylinders pass through the side plates and are fixed with positioning clamping plates, which solves the problem of driving the positioning clamping plates to move through the clamping cylinders, thereby clamping and positioning the lithium battery cells by the two positioning clamping plates, and driving the third rotating frame to rotate through the motor and the rotating shaft, thereby flipping the lithium battery cells; by arranging parallel connecting rods between the second rotating frame and the installation plate and configuring a motor, the connecting rods can rotate and drive the whole clamping component to move away from the processing table, so as to leave enough space for flipping the lithium battery cells; by setting structures such as the first rotating frame, the rotating seat, the second rotating frame and the third rotating frame, rotations in different directions are realized, making the flipping and handling of the lithium battery cells faster and more flexible, and the lithium battery cells can be flipped at the original processing position, flipped at adjacent processing positions and transferred and transported according to processing needs, improving the functionality of the handling mechanism.

[0006] Chinese Patent CN216037215U discloses a battery module flipping device, including a frame. It is characterized in that: a clamping and rotating mechanism and a module clamping mechanism are arranged on the frame.
