[0068] Working principle: When using, such as Figure 1 As shown, a battery cell tray with battery cells is placed on the feeding tray 2021. The positive and negative terminals of the battery cells on the battery cell tray face the same direction. The battery cell tray can be clamped by the clamping cylinders 2022 on both sides. The controller 7 controls the feeding cylinder 201 to start. After the feeding cylinder 201 starts, it pushes the feeding tray 2021 closest to it. The two feeding trays 2021 are connected by a connecting rod 2023. In this way, the feeding cylinder 201 can push multiple feeding trays 2021 to move. The distance sensor 203 detects the distance to the feeding tray 2021 facing it. The distance information is transmitted to the controller 7, so that the controller 7 can control the position of the feeding trays 2021, so that the feeding trays 2021 can move to the underside of the gripping robot arm in sequence.

[0069] The controller 7 controls the deflection motor 3101 to start. After the deflection motor 3101 starts, it drives the longitudinal stage 3103 to move up and down. The longitudinal stage 3103 drives the telescopic stage 3104 to move. The telescopic stage 3104 drives the lower pressure plate 3100 to move. The clamping electric cylinder 3108 and the suction cup 3106 installed on the lower pressure plate 3100 follow the movement of the lower pressure plate 3100, thereby adjusting the vertical distance between the suction cup 3106 and the battery cell. The distance sensor 8 detects the vertical height of the lower pressure plate 3100. The telescopic electric cylinder 3109 pushes the telescopic stage 3104 to extend and retract. The telescopic stage 3104 drives the lower pressure plate 3100 to move to the upper part of the battery cell. The distance sensor 7 measures the distance between the longitudinal stage 3103 and the telescopic stage 3104, thereby controlling the movement position of the telescopic stage 3104 to ensure that the suction cup 3106 can be aligned with the battery cell.

[0070] Once the suction cup 3106 is aligned with the battery cell, the downward-moving electric cylinder 3105 is activated, causing the lower pressure plate 3100 to move downward, bringing the suction cup 3106 into contact with the surface of the battery cell. Then, the air pump is activated, using suction to hold the battery cell under the suction cup 3106. Next, the deflection motor 3101 is activated, causing the longitudinal stage 3103 to rotate. The longitudinal stage 3103 then rotates the telescopic stage 3104, which in turn rotates the downward-moving electric cylinder 3105 and the lower pressure plate 3100 below it. The lower pressure plate 3100 then rotates the suction cup 3106 and the battery cell held below it, rotating 90 degrees to position the battery cell above the welding table 4203. The controller 7 then controls the downward-moving electric cylinder 3105 to extend, moving the battery cell... The battery is placed into the limiting slot; then the controller 7 controls the Z-motor to rotate back, repeating the above steps to transfer the battery on the cell tray to the remaining slots; the controller 7 controls the linear motor 3201 to rotate, the linear motor 3201 drives the screw 3202 to rotate, the screw 3202 drives the connecting block 3205 to move on the screw 3202, and the connecting block 3205 drives the transverse plate to move, so that when placing the cell, it is convenient to align with the corresponding slot. The distance sensor 3206 detects the moving distance of the transverse stage 3102, and the corresponding distance information is transmitted to the controller 7, so that the controller 7 can control the linear motor 3201, thereby controlling the moving distance of the transverse stage 3102.

[0071] After the battery cell is placed in the slot, the controller 7 starts the rotating cylinder 42051. The rotating cylinders 42051 on both sides of the penetration slot 42054 rotate and drive the battery cell to rotate, so that the positive terminal of one battery cell overlaps with the negative terminal of the other battery cell. At this time, the linear motor 3201 is controlled to move, and the lower pressure plate 3100 is moved to the upper part of the penetration slot 42054, so that the upper mold table 3107 is aligned with the welding head 4202. Then, the controller 7 starts the lifting cylinder 4101, which drives the ultrasonic welding machine 4201 to move upward, so that the welding head 4202 contacts the positive and negative terminals of the overlapping battery cell. Then, the controller starts the pressing cylinder 3108, which presses the upper mold table 3107 on the upper part of the positive and negative terminals, and starts the ultrasonic welding machine 4201 to connect the positive and negative terminals of the two battery cells, completing the series connection of the two battery cells.

[0072] After welding a pair of battery cells, the push-pull electric cylinder 52053 is activated. The push-pull electric cylinder 52053 drives the support plate 5101 to move. The movement of the support plate 5101 drives the movable table 4204 to move. The movable table 4204 drives the alignment component 61 to move, thereby driving the movement of the battery cells. After welding one set of battery cells, it is convenient to weld another set of battery cells.

[0073] After welding is completed, the rotary motor 52052 is started by the controller 7. The rotary motor 52052 drives the rotating frame 52051 to rotate, and the rotating frame drives the support plate 5101 to rotate. The support plate 5101 drives the battery cell on top of it to rotate to the lower part of the inspection mechanism 6. Then, the pressing cylinder 6302 is started, and the pressing cylinder 6302 drives the inspection plate 6303 to move down. The inspection plate 6303 drives the inspection probe 6304 to move down to the welding position of the battery cell. Then, the flaw detector 6301 is started, and the inspection probe 6304 is used to inspect the battery cell for flaws and detect the welding quality.
