A seventh cylinder 8 is located at the upper end of the frame 1, directly opposite the first opening. The output end of the seventh cylinder 8 has a first push block, used to push the core into the second track 202. Under the squeezing action of multiple cores, the core in the second track 202 can automatically enter the third track 203 along the curvature of the inner wall of the second track 202.

[0023] Furthermore, as a preferred embodiment, the ultrasonic welding mechanism 3 includes an ultrasonic welding machine 301 and a welding head 302. The welding head 302 is disposed at the lower end of the ultrasonic welding machine 301 and connected to the ultrasonic welding machine 301. In this embodiment, both the ultrasonic welding machine 301 and the welding head 302 are existing structures. By inserting the welding head 302 into the middle of the core and extending it to the bottom of the core, the negative electrode of the core is welded together with the base of the core.

[0024] Furthermore, as a preferred embodiment, the system also includes a mounting plate 303, a first slide rail 304, a first slider 305, a first cylinder 306, and a positioning mechanism 307.

The first cylinder 306 is located at the upper end of the mounting plate 303, and its output end is connected to the first slider 305. The positioning mechanism 307 is located on the other side of the third track 203. The first cylinder 306 drives the first slider 305 to move on the first slide rail 304, thereby causing the ultrasonic welding machine 301 to move up and down, thus adjusting the position of the welding head 302. The positioning mechanism 307, located on the other side of the third track 203, is used to position the core to ensure the accuracy of the welding position.

[0025] Furthermore, as a preferred embodiment, the positioning mechanism 307 includes a second cylinder 308 and a positioning plate 309. A first notch 207 is provided on the other side of the third track 203. The positioning plate 309 is slidably disposed within the first notch 207. The second cylinder 308 is mounted on the upper end of the frame 1, and the output end of the second cylinder 308 is connected to the positioning plate 309. The second cylinder 308 is used to push the positioning plate 309 to move within the first notch 207, thereby pushing the core to move. Through the cooperation between the positioning plate 309 and the inner wall of the third track 203, the core is clamped and fixed, preventing the core from shaking, so that the welding head 302 can be smoothly inserted into the core.

[0026] Furthermore, as a preferred embodiment, the edge sealing mechanism 4 includes a first mounting frame 401, a third cylinder 402, a second motor 403, a first rotating head 404, and a pressure roller mechanism 405.

The two nuts 413 are located on both sides of the pressure roller 412.

[0028] In operation, the third cylinder 402 drives the second motor 403 and the first rotating head 404 to descend, causing the first rotating head 404 to insert into the core shell. The second motor 403 drives the first rotating head 404 to rotate, causing the core to rotate as well. Simultaneously, the fourth cylinder 410 pushes the pressure roller mechanism 405 to move along the second slide rail 407, causing the pressure roller 412 to contact the core shell, thereby squeezing the core shell. Then, the third motor 409 drives the pressure roller 412 to rotate, achieving rolling of the core shell and forming a sealing groove, sealing the core inside the shell. This prevents the core from detaching from the shell and avoids leakage of electrolyte from the inner wall. The position of the pressure roller 412 can be fixed by the engagement of the threaded rod 411 and the nut 413, and the height of the pressure roller 412 can be adjusted to accommodate cores of different heights, improving the versatility of the equipment.

[0029] Furthermore, as a preferred embodiment, the grinding mechanism 5 includes a second mounting bracket 501, a fifth cylinder 502, a fourth motor 503, and a second rotating head 504.

The output end of the fifth cylinder 502 is connected to the fourth motor 503, and the output end of the fourth motor 503 is connected to the second rotating head 504. The fifth cylinder 502 drives the fourth motor 503 to move up and down, while the fourth motor 503 drives the second rotating head 504 to rotate. In use, the fifth cylinder 502 drives the fourth motor 503 and the second rotating head 504 to descend, causing the second rotating head 504 to insert into the outer shell of the core. Then, the fourth motor 503 drives the second rotating head 504 to rotate the core synchronously.

[0030] Furthermore, as a preferred embodiment, it also includes a second base plate 505, a third slide rail 506, a third slider 507, a sixth cylinder 508, a fifth motor 509, and a grinding wheel 510.

Then the fifth motor 509 drives the grinding wheel 510 to rotate, and in conjunction with the rotation of the core itself, to achieve the grinding treatment of the inner wall of the packaging groove, making the inner wall of the packaging groove smoother and burr-free.

[0031] In this embodiment, a first proximity sensor 10 is provided at one end of the first track 201, and the first proximity sensor 10 is used to detect the position of the core.

[0032] In this embodiment, a second proximity sensor 11 is set on one side of the third track 203, directly opposite the ultrasonic welding machine 301, to detect the position of the core, so that the welding head 302 can be accurately inserted into the core to weld the chassis and the negative electrode.

[0033] In this embodiment, one end of the third track 203 is connected to the second track 202, and the other end of the third track 203 is provided with a third proximity sensor, an eighth cylinder and a second push block. The third proximity sensor is used to detect the position of the core, and the output end of the eighth cylinder is connected to the second push block to push the core into the fourth track 204.

[0034] One end of the fourth track 204 is connected to the third track 203.

A fifth proximity sensor 13 is provided on the side wall of the fifth track 205, directly opposite the pressure roller 412, to detect the position of the core, so that the first rotating head 404 can be smoothly inserted into the outer shell of the core.

[0035] One end of the fifth track 205 is connected to the fourth track 204. The other end of the fifth track 205 is equipped with a sixth proximity sensor, a tenth cylinder and a fourth pusher. With the cooperation of the sixth proximity sensor, the tenth cylinder and the fourth pusher, the core can be pushed into the sixth track 206. On the other side of the sixth track 206, opposite the position of the grinding wheel 510, a seventh proximity sensor 14 is provided to detect the position of the core so that the grinding wheel 510 can accurately enter the encapsulation groove.

[0036] In this embodiment, the first motor, second motor 403, third motor 409, fourth motor 503, fifth motor 509, first cylinder 306, second cylinder 308, third cylinder 402, fourth cylinder 410, fifth cylinder 502, sixth cylinder 508, seventh cylinder 8, eighth cylinder, ninth cylinder 9, tenth cylinder, first proximity sensor 10, second proximity sensor 11, third proximity sensor, fourth proximity sensor 12, fifth proximity sensor 13, sixth proximity sensor, and seventh proximity sensor 14 are respectively connected to the PLC controller. Control parameters are input through the touch screen 701, and then the PLC controller controls the operation of each component.

[0037] In this embodiment, two guide plates 15 and a spring 16 are arranged inside the sixth track 206. The two guide plates 15 are symmetrically arranged. One end of the guide plate 15 is rotatably connected to the inner wall of the sixth track 206, and the other end of the guide plate 15 is connected to the inner wall of the sixth track 206 through the spring 16. One end of the guide plate 15 is bent to facilitate the core entering between the two guide plates 15. The cooperation between the guide plates 15 and the spring 16 enables automatic calibration of the core's position, ensuring the core accurately enters directly below the second rotating head 504. The spring 16 allows the spacing between the two guide plates 15 to be adjusted, accommodating cores of different diameters.

[0038] In operation, the loading robot clamps the core and places it in the first track 201. Driven by the conveyor belt, the core moves. When the first proximity sensor 10 detects the core approaching, the seventh cylinder 8 drives the first pusher to push the core into the second track 202. Under the pressure of multiple cores, the core moves into the third track 203. When the second proximity sensor 11 detects the core, the first motor stops, and the second cylinder 308 pushes the positioning plate 309 to contact the core, thus positioning it. Then, the first cylinder 306 pushes the first slider 305, causing the ultrasonic welding machine 301 to move downwards, allowing the welding head 302 to insert into the core, achieving welding between the core chassis and the negative electrode. After welding, the first cylinder 306 drives the first slider 305, causing the ultrasonic welding machine 301 to move upwards, causing the welding head 302 to exit the core. Then, the first motor continues to operate, and the conveyor belt continues to move the core. When the third proximity sensor detects the core, the eighth cylinder drives the second pusher to move, causing the second pusher to push the core into the fourth track 204. When the fourth proximity sensor 12 detects the core, the ninth cylinder 9 operates, driving the third pusher to push the core into the fifth track 205. When the fifth proximity sensor 13 detects the core, the first motor stops operating, and the third cylinder 402 drives the second motor 403 to descend, causing the first rotating head 404 to enter the core's outer shell. Then, the fourth cylinder 410 pushes the second slider 408 to move the third motor 409, causing the pressure roller 412 to contact the core's outer shell. Simultaneously, the second motor 403 and the third motor 409 operate synchronously, driving the core and pressure roller 412 to rotate, thereby forming a sealing groove on the outer wall of the core's outer shell. Then, the first motor operates again, continuing to drive the core to move. When the sixth proximity sensor detects the core, the tenth cylinder drives the fourth pusher to push the core into the sixth track 206. When the seventh proximity sensor 14 detects the core, the first motor stops working. At this time, the fifth cylinder 502 drives the fourth motor 503 to descend, so that the second rotating head 504 inserts into the core shell. Then, the sixth cylinder 508 drives the third slider 507 to move, driving the fifth motor 509 and the grinding wheel 510 to move horizontally, so that the grinding wheel 510 enters the packaging groove. Then, the fifth motor 509 and the fourth motor 503 work simultaneously, driving the core and the grinding wheel 510 to rotate, thereby polishing the inner wall of the packaging groove. The processed core continues to move under the action of the conveyor belt and is then moved to the external storage box under the action of the unloading robot.
