[0028] In one embodiment, the aluminum plug installation station 3 includes a four-axis robot 301, an aluminum plug vibration feeding mechanism 302, a first CCD detection camera 303, and a first aluminum plug pressing mechanism 304. The aluminum plug is placed in the vibratory feeder of the aluminum plug vibration feeding mechanism 302 and is fed by vibration. The first CCD detection camera 303 is located above the aluminum plug vibration feeding mechanism 302 and is used to detect the orientation of the vibrated aluminum plug. If the front is facing up, the end effector 3011 of the four-axis robot 301 grasps it by vacuum adsorption. If the back is facing up, vibration continues until the front is facing up. After the end effector 3011 grasps the front-facing aluminum plug, it is transferred to the electric motor at the station. The aluminum plug is pressed into the second positioning hole 903 on the capacitor positioning component 9. The first aluminum plug pressing mechanism 304 includes a first cylinder 3041, a linear guide rail 3042, and a first pressing head 3043. The piston rod of the first cylinder 3041 is connected to the first pressing head 3043, and the first pressing head 3043 is slidably mounted on the linear guide rail 3042. The first cylinder 3041 drives the first pressing head 3043 to slide down along the linear guide rail 3042, thereby pressing the aluminum plug into the liquid injection hole of the capacitor 8. In addition, in order to ensure that the aluminum plug is accurately placed in the second positioning hole 903 on the capacitor positioning component 9, a fourth CCD detection camera 305 is set at this station to detect whether the aluminum plug is placed in place.

[0029] In one embodiment, the aluminum plug pressing station 4 is provided with a second aluminum plug pressing mechanism 401 and a second CCD detection camera 402. The second aluminum plug pressing mechanism 401 includes a second cylinder 4011, a second pressing head 4012, a third cylinder 4013 and a third lifting plate 4014. The third cylinder 4013 drives the third lifting plate 4014 to rise and position the capacitor 8, and the second cylinder 4011 drives the second pressing head 4012 to press down and further press the aluminum plug into the injection hole. The second CCD detection camera 402 detects the assembled body after pressing to ensure that the assembly is in place.

[0030] In one embodiment, the laser welding station 5 is equipped with a laser welding machine 501 and a dust collection hood 502. The laser welding machine 501 is slidably mounted on the support frame 503, and the dust collection hood 502 is mounted above the capacitor positioning component 9 at the welding station 5. The aluminum plug is welded by the laser welding machine 501, and the dust collection hood 502 is connected to an external fan to capture the spatter and other debris generated during the welding process.

[0031] In one embodiment, the inspection and unloading station 6 includes a third CCD inspection camera 601 and a second pneumatic gripper 602 mounted on a second XZ linear module 603. In addition, a scrap collection box 13 is also provided at the inspection and unloading station 6. The capacitor with welded aluminum plugs is inspected by the third CCD inspection camera 601. Qualified products are gripped and unloaded by the second pneumatic gripper 602 driven by the second XZ linear module 603, and unqualified products are gripped and placed into the scrap collection box 13 by the second pneumatic gripper 602 driven by the second XZ linear module 603.

[0032] The working principle is as follows: The feeding assembly 1 transfers capacitor 8 from the circular conveyor line 10 to the capacitor receiving slot 11 on the turntable 7. The turntable 7 then rotates, moving capacitor 8 to the laser cleaning station 2. At this station, the corresponding lifting cylinder 12 operates, lifting capacitor 8 upwards and positioning it using capacitor positioning components 9. The injection hole is then laser-cleaned by the laser cleaning machine 201. The capacitor 8 is then rotated to the aluminum plug installation station 3, where it is again lifted and positioned. The aluminum plug is then installed, and the first aluminum plug pressing mechanism 304 initially presses the aluminum plug down. The turntable 7 continues to rotate to the aluminum plug pressing station 4, where capacitor 8 is lifted and positioned, and the aluminum plug is further pressed down to ensure proper assembly. Subsequently, turntable 7 rotates to laser welding station 5 for laser welding. After welding, the capacitor with welded aluminum plugs is inspected at inspection and unloading station 6 by the third CCD inspection camera 601. Qualified products are picked up and unloaded by the second pneumatic gripper 602 driven by the second XZ linear module 603, while unqualified products are picked up and placed into the waste collection box 13 by the second pneumatic gripper 602 driven by the second XZ linear module 603. In addition, the various stations of this utility model can achieve uninterrupted circulation. For example, after laser cleaning is completed at laser cleaning station 1, the capacitor is transferred to aluminum plug installation station 3, and the subsequent capacitors 8 continue to be transferred to laser cleaning station 1 for laser cleaning.
