[0012] A further solution: the number of clamping components is four, used to clamp the four corners of the battery cell.

[0013] A further solution: The tray is provided with protrusions for supporting the battery cells.

[0014] A further embodiment: The side plate of the frame is provided with a lifting slide rail; the power unit includes a tank chain and a rotating motor connecting the tilting plate and the frame, and the tank chain drives the rotating motor to move up and down in a restricted manner in the lifting slide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a clamping component to precisely grasp battery cells from a tray and a flipping plate to quickly flip the cells. After flipping, the cells are conveyed to the picking mechanism, while the flipping plate automatically returns to its initial position, ready for the next grasping operation. The entire process requires no manual intervention, enabling continuous operation and significantly improving work efficiency.

[0017] Furthermore, the flipping plate has two parallel gripping stations on both ends, further optimizing the gripping and flipping process of the battery cells and effectively improving operational efficiency. After the flipping plate returns to its initial position, it can directly grip new battery cells without flipping them again, simplifying the process steps, significantly saving operation time, and significantly improving production efficiency and equipment utilization while ensuring process accuracy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 In this embodiment, a battery cell flipping device includes a frame 1, a tray 2 located at the bottom of the frame 1, and a clamping and flipping mechanism 3 located above the tray 2. The clamping and flipping mechanism 3 includes a flipping plate 31, clamping components 32 connected to both ends of the flipping plate 31, and a power unit. The flipping plate 31 is connected to the frame 1 via the power unit and can flip and lift. The battery cell is pre-placed on the tray 2. After the clamping components 32 on the bottom end of the flipping plate 31 grasp the battery cell, the power unit drives the flipping plate 31 to flip horizontally 180° along its centerline, and then drives the battery cell upwards to prepare for the next step of welding the electrode tabs.

[0025] Furthermore, the clamping assembly 32 includes a support post 321 and a jaw 322 located at one end of the support post 321. There are four clamping assemblies 32, which clamp the four corners of the battery cell through the jaws 322, thereby realizing actions such as flipping and lifting of the battery cell.

[0026] Furthermore, the other end of the support column 321 is slidably connected to the flip plate 31. A parallel track is provided on the end face of the flip plate 31, and the support columns 321 on both sides are driven by a translation motor to move closer or further apart, so as to grasp the battery cells on the tray 2.

[0027] Furthermore, this device also includes a material handling mechanism 4, which includes a gripper 41 and a lifting cylinder 42 that drives the gripper 41 to rise and fall. Driven by the power unit, the tilting plate moves upwards. After reaching a preset height, the clamping assembly 32 releases the battery cell, and then the gripper 41 grabs the battery cell, preparing it for the next welding process. Simultaneously, the power unit lowers the tilting plate 31 to its initial position and continues to grab another battery cell from the tray 2, continuing the operation.

[0028] Furthermore, a horizontal slide rail is provided on the top plate 11 of the frame 1, and the non-extension end of the lifting cylinder 42 slides back and forth in a restricted manner in the horizontal slide rail. There are two material handling mechanisms 4, which jointly grab the battery cell from both ends. The horizontal guide rail (not shown in the figure) and the lifting cylinder 42 realize the horizontal and vertical movement of the gripper 41, which facilitates the operation of grabbing the battery cell.

[0029] Furthermore, the flip plate 31 has two parallel stations on its end face, and each parallel station is equipped with a set of clamping components 32. By setting multiple stations, the efficiency of electric gripping and flipping of the battery cell is improved.

[0030] Furthermore, the tray 2 is provided with protrusions for supporting the battery cells. The protrusions create a certain gap between the battery cells and the surface of the tray 2, facilitating the gripping of the battery cells when the jaws 322 move horizontally. The battery cells are pre-transmitted to a preset position on the tray 2 by another conveying device, awaiting gripping and flipping.

[0031] Furthermore, the side plate 11 of the frame 1 is provided with a lifting slide rail 111; the power unit includes a tank chain 34 and a rotating motor 33 connecting the tilting plate 31 and the frame 1. The tank chain 34 drives the rotating motor 33 to move up and down in a restricted manner within the lifting slide rail 111. The tank chain 34 is fixed to the outside of the side plate 11, one end of the tank chain 34 is connected to the rotating motor 33, and the other end is pulled by a motor, realizing the operation of the rotating motor 33 driving the tilting plate 31 to tilt.

[0032] In operation, the battery cell is pre-transferred to a preset position on the tray 2. The clamping assembly 32 at the bottom of the flipping plate 31 moves downwards under the drive of the power unit, and the support columns 321 on both sides move closer together to grip the battery cell. The flipping plate 31 continues to move upwards to a preset height and then flips 180°, flipping the battery cell to its upper surface. It then continues to rise to the preset height, and the grippers 41 move closer to the battery cell until it is clamped. Simultaneously, the support columns 321 on both sides of the battery cell move away from each other, releasing the battery cell. The grippers 41 move upwards under the action of the lifting cylinder 42, handing the battery cell over to the receiving component for the next welding process. After the handover is completed, the grippers 41 return to the gripping position. After the clamping assembly 32 releases the battery cell, the flipping plate 31 moves downwards, returning to its initial position, and continues the next round of battery cell gripping.
