[0046] like Figures 1 to 3 As shown, the transportation of the battery half-sheet is completed by a cooling steering mechanism and a transfer mechanism. The cooling steering mechanism includes a cooling track, a steering structure and a half-sheet lower plate structure.

A cooling drive motor 106 is arranged below the cooling track, and a cooling drive wheel 107 is installed at the driving end of the cooling drive motor 106 and one end of the cooling main shaft 104, and the cooling drive wheels 107 are connected by belt transmission, and a cooling fan 108 is installed above the cooling track.

[0048] The two half-cell battery cells cut in front are placed on the cooling track, and the cooling drive motor 106 controls the cooling drive wheel 107 to rotate. Driven by the belt, the cooling main shaft 104 rotates, and the negative pressure belt 102 rotates between the cooling main shaft 104 and the cooling slave shaft 105. The negative pressure tube 101 is in negative pressure, and the negative pressure hole 103 is controlled to adsorb and fix the battery half-cell, ensuring the position of the battery half-cell. After passing through the cooling fan 108, the cooling treatment after laser cutting is carried out.

[0049] The steering structure includes a bogie 201, a steering vertical movement cylinder 202 and a steering motor 203. The steering vertical movement cylinder 202 is arranged at the upper end of the bogie 201, and the steering motor 203 is fixed on the driving end of the steering vertical movement cylinder 202. The driving end of the steering motor 203 is vertically downwardly connected with a steering suction nozzle 204. Steering adjustment slide rails 205 and a steering adjustment screw 206 are installed on both sides of the upper end of the bogie 201. A steering adjustment slider and a steering adjustment nut are connected above the fixed end of the steering vertical movement cylinder 202. The steering adjustment screw 206 is threadedly connected to the steering adjustment nut. The steering adjustment slider slides on the steering adjustment slide rail 205, and a steering adjustment handwheel 207 is installed at one end of the steering adjustment screw 206.

[0050] The steering adjustment hand wheel 207 is turned in advance to control the rotation of the steering adjustment screw 206, so that the steering vertical movement cylinder 202 moves under the relative action of the steering adjustment slider and the steering adjustment slide rail 205, corresponding to the position of the battery half-sheet. When the battery half-sheet moves to one side of the bogie 201, the steering vertical movement cylinder 202 controls the steering suction nozzle 204 to move downward, and absorbs the battery half-sheet that needs to be reversed. Under the control of the steering motor 203, the absorbed battery half-sheet is rotated 180 degrees, and the steering vertical movement cylinder 202 then puts the turned battery half-sheet back on the original negative pressure belt 102.

[0051] The half-sheet lower plate structure includes a half-sheet fixed frame 301, a half-sheet movable frame 302 and a half-sheet vertical cylinder 303. The half-sheet movable frame 302 moves horizontally on the half-sheet fixed frame 301. The half-sheet vertical cylinder 303 is fixed on the half-sheet movable frame 302. A half-sheet I-shaped plate 304 is connected to the driving end of the half-sheet vertical cylinder 303. A half-sheet lower plate suction nozzle 305 is fixed on the half-sheet I-shaped plate 304.

The half-piece moving frame 302 is fixedly connected to the half-piece synchronous belt 309.

[0052] When the battery halves with the same orientation move to the end of the cooling track, the half-sheet vertical movement cylinder 303 controls the half-sheet I-plate 304 to move downward, allowing the half-sheet lower plate suction nozzle 305 to absorb the two battery halves, and the half-sheet motor 308 is started. The half-sheet synchronous wheel 307 and the half-sheet synchronous belt 309 drive the half-sheet moving frame 302 to move horizontally, and the two battery halves on the half-sheet I-plate 304 are transferred to the transfer mechanism.

[0053] like Figures 4 to 6 As shown, the transfer mechanism includes a half-cell transfer track 401, a robot mechanism and a fragment detection structure. The received battery half-cell is transported from the half-cell transfer track 401, and after being air-cooled and snap-fitted and positioned by the robot mechanism, the fragment detection structure performs fragment detection on the battery half-cell.

[0054] Battery half-sheet snapping cylinders 402 are installed on both sides of the front end of the half-sheet transfer track 401, and a snapping rod 403 is connected to the driving end of the battery half-sheet snapping cylinder 402, and a snapping wheel 404 is installed on the snapping rod 403.

One end of the half-sheet transfer track 401 is connected to a half-sheet transfer motor 408, and the driving end of the half-sheet transfer motor 408 and one end of the half-sheet main shaft 405 are both installed with half-sheet transfer synchronous wheels, and the half-sheet transfer synchronous wheels are connected by belt transmission.

When passing through the battery half-sheet snapping cylinder 402, the battery half-sheet snapping cylinder 402 controls the snapping rod 403 with the snapping wheel 404 to snap to the middle of the half-sheet transfer track 401, so that the position of the battery half-sheet can be corrected to the middle.

[0056] The manipulator mechanism includes a manipulator base 501, a blowing fan 502 and a positioning rod 503. The half-piece transfer track 401 passes through the middle of the manipulator base 501. The blowing fan 502 is located at the front end of the manipulator base 501. A positioning slide rail 504 is installed horizontally at the rear end of the manipulator base 501.

[0057] The robot base 501 crosses over the top of the half-cell transfer track 401, saving space for installing an additional robot next to it. When passing under the blowing fan 502, the blowing fan 502 blows air to cool the battery half-cell. Then, after passing through the robot base 501, the positioning motor 509 controls the positioning synchronous wheel to rotate, driving the movement of the positioning synchronous belt, and pulling the positioning rod 503 to the middle to snap together. After the positioning rod 503 snaps together and positions the battery half-cell in transit with the positioning wheel 505 again, it is detected by the broken fragment detection structure. The battery half-cell that meets the requirements is sucked up by the grasping robot 506 and controlled by the robot suction cup 507 and transferred to the positioning mechanism. If it does not meet the requirements, it is placed in the half-cell broken plate 510 on the side for installation and waits for manual processing.

[0059] After the robot mechanism assists in the snapping and positioning, the battery half-cell is precisely controlled to be in the middle position of the half-cell transfer track 401, corresponding to the bottom of the half-cell detection camera 602. In the case of front-to-back offset, the handwheel on the half-cell adjustment screw is turned to rotate the half-cell adjustment screw. Under the action of the half-cell adjustment nut, the half-cell detection light source 603 can be fine-tuned forward and backward along the half-cell adjustment slide rail 604, corresponding to the position of the battery half-cell, and the half-cell detection camera 602 can take pictures for detection.
