[0061] The working principle of this utility model:

[0062] In this embodiment, the gripper 16 moves in the front-back direction of the device, and the first forward gripping unit 9 and the first swing gripping unit 10 are opposite each other in the left-right direction.

[0063] The side pressure assembly, lifting assembly, and tightening assembly are all located on the top of the frame 1. The side pressure frame 11 on the side pressure assembly is located above the lifting assembly and the tightening assembly. The side pressure frame 11 is hollow and has a side pressure space. The projection surface of the lifting beam 2 is located on the projection surface of the side pressure space. The tightening assembly is located outside the lifting assembly.

[0064] The first forward clamping unit 9 and the first swing clamping unit 10 are arranged opposite to each other. The forward driving element 91 causes the forward pressing block 92 to move horizontally left and right to clamp one end of the tray. The swing driving element 101 causes the swing pressing block 102 to swing through the movable part 20. In this embodiment, the swing pressing block 102 has a hook-shaped structure design and is not limited to a hook-shaped structure design, so as to tightly hold the top of the tray. Since the tray needs to flow horizontally into the lifting beam 2, the first swing clamping unit 10 is set to allow the tray to pass through the top of the open first swing clamping unit 10 and flow into the feeding guide rail 27. At this time, the rollers on the feeding guide rail 27 are driven by the corresponding feeding driving element 8, so that the tray placed on the feeding guide rail 27 is moved horizontally towards the first forward clamping unit 9 to ensure that the tray is accurately delivered to the top of the lifting beam 2.

[0065] When the pallet is precisely delivered to the top of the lifting beam 2, the controllable positioning lifting structure 32 drives the positioning column 31 to perform the first positioning of the bottom of the pallet. The first positioning drive unit drives the positioning hole on the lifting beam 2 to perform the second positioning of the bottom of the pallet. The extension end of the first positioning drive cylinder 4 drives the inclined slider 5 to move horizontally. The top surface of the inclined slider 5 is inclined. The lifting roller 6 abuts against the inclined surface at the top of the inclined slider 5. When the inclined slider 5 moves, the lifting roller 6 at the bottom of the lifting beam 2 moves with the inclined slider 5, causing the lifting beam 2 to move up and down, thereby realizing the up and down adjustment of the pallet to complete the second positioning. After the second positioning is completed, the forward drive element 91 causes the forward pressing block 92 to move horizontally to press the pallet. The swing drive element 101 causes the swing pressing block 102 to lock the pallet through the movable part 20.

[0066] The unlocking mechanism is used to unlock the side panels and middle partitions on the tray, which are not shown in the illustrations in this embodiment. The side panels and middle partitions on the tray serve to separate several cells within the cell module.

[0067] After the tray is positioned and installed, the battery cells on the tray are installed, and the battery cell modules are then installed on the tray. The side pressure lifting unit 131 drives the side pressure plate 13 to move up and down, adjusting it to an appropriate position. The side pressure drive unit controls the two side pressure plates 13 to move closer together to apply side pressure to the battery cell modules. At this time, the gripper 16 clamps the middle partition of the tray, further fixing the position of the tray and completing the installation and positioning of the tray and battery cell modules. The photoelectric detection element 26 can detect the middle partition. When the floating range of the middle partition exceeds the limit position, it triggers the photoelectric detection element and sounds an alarm. The photoelectric detection element is a photoelectric switch. In this embodiment, the gripper 16 consists of two gripping arms, which are controlled to open and close by a control cylinder connected to the gripper 16. In addition, the gripper 16 is connected to a telescopic cylinder for driving the gripper 16 to move back and forth. The telescopic end of the telescopic cylinder is connected to the gripper 16 or the control cylinder, driving the control cylinder and the gripper 16 to move back and forth together.

[0068] The side pressure drive unit can be a servo motor that drives a positive and negative threaded lead screw through a gearbox. The servo motor corresponds to the lead screw drive motor 15 and the gearbox, and the transmission lead screw 14 is a positive and negative threaded lead screw, thereby controlling the horizontal reciprocating movement of the side pressure moving structure 12 and the side pressure plate 13.

[0069] In this embodiment, the pallet can be fed into or out of the lifting beam 2 via the feeding mechanism. The first positioning mechanism can accurately position the pallet through the first positioning unit and use the first positioning drive unit to make the pallet move up and down. The side pressure plate 13 of the side pressure component can move up and down, and after adjusting to different heights, it can side pressure the battery cell module. The tightening component can press and tighten the battery cell module. It has a high degree of automation, accurate positioning, and high working efficiency, and completes the pre-stacking operation of the battery cell module.

[0070] The main function of the tightening assembly is to provide the clamping power for the clamping mechanism on the end face of the battery cell module. The clamping mechanism on the end face of the battery cell module includes a connected screw, which is not shown in this figure. The tightening moving unit 19 can drive the tightening drive unit 18 and the tightening block 17 to move forward. After the tightening moving unit 19 drives the tightening block 17 to the tightening position, the tightening drive unit 18 drives the tightening block 17 to rotate, thereby driving the screw of the mechanism for clamping the end face of the battery cell module to rotate, so as to provide end pressure power.
