At the same time, the welding head 61 is arranged on the welding lifting platform 62 and moves up and down in the vertical direction, that is, the welding head 61 can move up and down on the welding lifting platform 62, so that the welding head 61 can approach or away from the workstations 21 on the turntable 2, thereby realizing the welding of the base and the upper cover on the workstations 21. It is worth pointing out that the welding head 61 is an ultrasonic welding head 61, which is mature in technology, widely used, and can be directly purchased on the market, which can meet the use requirements, so its specific structure and model specifications are not described here.

[0043] More specifically, the blanking assembly 7 is arranged beside the turntable 2 and below the workstations 21, and the finished magnetic sheet is automatically taken off from the workstations 21 through the blanking assembly 7, realizing automatic blanking.

At this time, the riveting assembly 8 is further arranged on the rack 1 between the welding assembly 6 and the blanking assembly 7. At this time, the riveting assembly 8 further includes a riveting table 81, a riveting feeding part 82 and a riveting pressing part 83. The riveting feeding part 82 is arranged on the rack 1 beside the turntable 2, which realizes the stable installation of the riveting feeding part 82 and can deliver the rivets to the side of the turntable 2, providing conditions for subsequent installation of the rivets on the base and the upper cover. At the same time, the riveting pressing part 83 is vertically installed beside the riveting feeding part 82 and moves up and down in the vertical direction, so that the riveting pressing part 83 can press the rivet subsequently, so as to rivet the rivet on the base and the upper cover. In addition, the riveting table 81 is arranged directly below the riveting pressing part 83, and the end of the riveting feeding part 82 is located between the riveting pressing part 83 and the riveting table 81, that is, the rivet can be delivered to the riveting pressing part 83 and the riveting table 81 through the riveting feeding part 82, and the riveting table 81 provides a placement carrier for the base and the upper cover to be riveted, so that the rivet can be riveted to the base and the upper cover when the riveting pressing part 83 is pressed down subsequently, completing the riveting process. It is worth noting that the blanking assembly 7 is replaced from the side of the turntable 2 to the side of the riveting table 81 and is located below the riveting table 81. At this time, the air nozzle 71 in the blanking assembly 7 is obliquely upwardly aligned with the riveting table 81, that is, after riveting is completed, the air nozzle 71 of the air supply machine box supplies air, and the product on the riveting table 81 that has been riveted is blown off from the riveting table 81 through the air nozzle 71, meeting the automatic blanking requirement.

[0045] More specifically, the rivet feeding part 82 is provided with a feeding guide plate 821, and the feeding guide plate 821 is provided with a rivet guide groove 8211 arranged along the length direction of the feeding guide plate 821, that is, the rivet guide groove 8211 in the feeding guide plate 821 provides a conveying channel for the rivet. Moreover, one end of the feeding guide plate 821 extends between the rivet pressing down part 83 and the rivet pressing table 81, so that the rivet can be continuously conveyed to the rivet pressing table 81 through the rivet guide groove 8211. In addition, the feeding guide plate 821 is rotatably installed on the rack 1, that is, the feeding guide plate 821 can rotate on the rack 1, so that one end of the feeding guide plate 821 can be away from or close to the rivet pressing table 81, which provides conditions for the rivet to be close to the rivet pressing table 81 when it is sent to the reinforcing hole in the bottom cover and the upper cover in the subsequent process, and to be away from the rivet pressing table 81 when the rivet pressing down part 83 is pressed down to realize riveting. In addition, the side of the feeding guide plate 821 close to the rivet pressing down part 83 is provided with a guide plate 822, and the guide plate 822 is arranged obliquely, so that the upper end of the guide plate 822 is away from the rivet pressing down part 83, and the lower end of the guide plate 822 is close to the rivet pressing down part 83, so that the distance between different positions of the guide plate 822 and the rivet pressing down part 83 is different. At the same time, the rivet pressing down part 83 is provided with a guide rod 823 extending towards the side of the guide plate 822, so that the guide rod 823 can follow the rivet pressing down part 83 to move downward, and the end of the guide rod 823 is provided with a roller 824 which is pressed on the guide plate 822 through the roller 824, that is, when the rivet pressing down part 83 moves downward, the roller 824 at the end of the guide rod 823 also moves downward with the rivet pressing down part 83. Since the distance between the guide plate 822 and the rivet pressing down part 83 gradually decreases in the downward direction, the roller 824 pushes the feeding guide plate 821 away from the rivet pressing down part 83 by pushing the guide plate 822, which provides conditions for the rivet to be out of the rivet guide groove 8211 on the feeding guide plate 821 and avoid interfering with the riveting action. Moreover, the end of the feeding guide plate 821 extending to the rivet pressing table 81 and located at the slot of the rivet guide groove 8211 is provided with a limiting piece 825, which realizes the opening and closing of the slot of the rivet guide groove 8211 through the limiting piece 825, and meets the use requirement of sending out the rivet one by one. At this time, the limiting piece 825 includes a limiting hook 8251 and a first reset spring 8252, the limiting hook 8251 is rotatably installed on the feeding guide plate 821, and the hook head of the limiting hook 8251 extends to the slot of the rivet guide groove 8211 and enters the slot, that is, the hook head of the limiting hook 8251 can be withdrawn from or inserted into the slot of the rivet guide groove 8211 through the swing of the limiting hook 8251. At the same time, the limiting hook 8251 and the feeding guide plate 821 are provided with the first reset spring 8252, that is, the first reset spring 8252 can reset the limiting hook 8251 after swinging, which provides conditions for subsequent repeated operation.

[0046] It is worth pointing out that the pressing end of the riveting pressing part 83 is provided with a vertically downward arranged insertion pin, the riveting seat is provided with a corresponding ejector pin, the rivet is a hollow tubular structure, when the base and the upper cover to be riveted are transferred to the riveting seat, the ejector pin is inserted into the reinforcing hole, at this time, the riveting pressing part 83 moves downward, the insertion pin is inserted into the hollow of the rivet at the slot of the rivet guide groove 8211, at the same time, the feeding guide plate 821 moves away from the riveting pressing part 83, so that the insertion pin can drive the rivet to open the hook head of the limiting hook 8251, so that the rivet is ejected from the slot of the rivet guide groove 8211, and after the rivet is ejected from the slot of the rivet guide groove 8211, the first reset spring 8252 drives the limiting hook 8251 to reset and blocks the slot of the rivet guide groove 8211 again, avoiding the problem that other rivets in the rivet guide groove 8211 are ejected from the slot, at this time, the riveting pressing part 83 continues to move downward, the rivet is inserted into the reinforcing hole along with the insertion pin, and as the riveting pressing part 83 continues to move downward, the two ends of the insertion pin and the ejector pin can press the rivet, until the rivet is compressed and deformed, realizing the riveting operation of the base and the upper cover. In addition, the riveting pressing part 83 includes but is not limited to a gas cylinder, an electric cylinder or a hydraulic rod, which can satisfy the linear extension and retraction motion, so its specific structure is not described here.
