[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a hemming device for assembling a battery cap, including a hemming assembly 1, and auxiliary assemblies 3 are symmetrically and fixedly connected to the top of the hemming assembly 1;

[0026] The auxiliary assembly 3 includes a support frame 302 and a conveyor belt 301. A first electric push rod 304 is fixedly connected to one inner wall of the support frame 302. The driving end of the first electric push rod 304 is fixedly connected to a moving block 312. A second electric push rod 306 is fixedly connected to the outer surface of one side of the moving block 312. The driving end of the second electric push rod 306 is fixedly connected to a sliding block 313. An electric telescopic rod 307 is fixedly connected to the bottom of the sliding block 313. An installation plate 303 is fixedly connected to the bottom of the electric telescopic rod 307. A vacuum pump 308 is fixedly connected to the top of the installation plate 303. The output end of the vacuum pump 308 is fixedly connected to an installation pipe 311. One end of the installation pipe 311 away from the vacuum pump 308 is fixedly connected to a vacuum chuck 309.

[0027] As shown in Figure 1 , Figure 2 and Figure 4 , the top of the vacuum chuck 309 is fixedly connected to the bottom of the installation plate 303. A material guiding hopper 310 is fixedly connected to one inner wall of the support frame 302. Guide rods 305 are symmetrically and fixedly connected to the inner surface of the support frame 302. The two guide rods 305 pass through the moving block 312 and the sliding block 313 movably. When the moving block 312 and the sliding block 313 move, they will slide along the guide rods 305, making their movement more stable. And the cap can be adsorbed by the vacuum chuck 309. And under the action of the material guiding hopper 310, the dropped caps can be centrally collected.

[0028] As shown in Figure 1 , Figure 2 and Figure 4 , the position of the installation plate 303 is matched with the position of the conveyor belt 301. A rubber pad 314 is fixedly connected to the inner surface of the material guiding hopper 310. Through the rubber pad 314 inside the material guiding hopper 310, the dropped caps can be buffered to avoid bumping.

[0029] As shown inFigure 1 and Figure 2 As shown in Figure 2 , the edge wrapping component 1 includes a base 111. The top of the base 111 is fixedly connected to a workbench 101. Symmetrically fixed to the top of the workbench 101 are hydraulic rods 103. The driving ends of the two hydraulic rods 103 penetrate through the top of the workbench 101 movably. The driving ends of the two hydraulic rods 103 are fixedly connected to a moving plate 102. Inside the moving plate 102, two fixed rods 108 are connected through two bearings. By starting the hydraulic rods 103, the moving plate 102 is driven to move downward, thereby driving the two fixed rods 108 to move downward. At the same time, the fixed rods 108 can rotate on the moving plate 102 under the action of the bearings.

[0030] As Figure 1 and Figure 2 As shown in Figure 2 , rectangular blocks 105 are fixedly connected to the front surface of the workbench 101. First motors 106 are fixedly connected to the outer surfaces of the two rectangular blocks 105. The output ends of the two first motors 106 penetrate through the outer surfaces of the two rectangular blocks 105 movably. The output ends of the two first motors 106 are fixedly connected to rotating blocks 104. Deep groove ball bearings 107 are arranged on the outer surfaces of the two rotating blocks 104. By starting the first motors 106, the rotating blocks 104 can be driven to rotate, thereby driving the deep groove ball bearings 107 to rotate for the edge wrapping work of the cap.

[0031] As Figure 1 and Figure 2 As shown in Figure 2 , second motors 109 are symmetrically fixedly connected to the top of the base 111. The output ends of the two second motors 109 are fixedly connected to molds 110. By starting the second motors 109, the molds 110 can be driven to rotate along the axis of the second motors 109.

[0032] As Figures 1-4 As shown in Figures 1-4 , the bottoms of the two support frames 302 are fixedly connected to the top of the base 111. The bottoms of the two conveyor belts 301 are fixedly connected to the top of the base 111. Through the auxiliary component 3 on the support frame 302, the feeding and discharging work of the cap can be assisted.

[0033] Usage method and working principle of this device: The hydraulic rod 103, the first motor 106, the second motor 109, the conveyor belt 301, the first electric push rod 304, the second electric push rod 306, the electric telescopic rod 307, and the vacuum pump 308 are all electrically connected to an external controller. An ultrasonic sensor is provided on the conveyor belt 301 to cooperate with the controller to control the start of the conveyor belt 301, so that there is always a cap at the front of the conveyor belt 301 for subsequent adsorption by the vacuum chuck 309. When processing, start the electric telescopic rod 307 to move the mounting plate 303 downward, so that the vacuum chuck 309 fits with the cap at the front of the conveyor belt 301. Then start the vacuum pump 308. Thus, under the action of the mounting tube 311, suction is generated inside the vacuum chuck 309 to adsorb the cap. Then the electric telescopic rod 307 resets. Under the start of the first electric push rod 304 and the second electric push rod 306, the moving block 312 and the sliding block 313 will move stably along the guide rod 305 to move the vacuum chuck 309 to the top of the mold 110. Then start the electric telescopic rod 307 to move downward to move the cap onto the mold 110. Then, the automatic release valve on the vacuum pump 308 causes the vacuum chuck 309 to lose the adsorption of the cap. Then start the second electric push rod 306 and the electric telescopic rod 307 to reset, and move the mounting plate 303 away from above the mold 110. Then the hydraulic rod 103 drives the moving plate 102 and the fixed rod 108 to move downward to fix the cap on the mold 110. Then start the second motor 109 to rotate, driving the mold 110 and the cap to rotate. At the same time, the first motor 106 can be started to drive the rotating block 104 and the deep groove ball bearing 107 to rotate for the edge wrapping work of the cap. When the edge wrapping is completed, reset the hydraulic rod 103. Then start the second electric push rod 306 to drive the sliding block 313 and the electric telescopic rod 307 to move. Then start the electric telescopic rod 307 to drive the mounting plate 303 to move downward to make the vacuum chuck 309 fit with the cap. Thus, under the cooperation of the vacuum chuck 309 and the vacuum pump 308, after adsorbing the processed cap, first start the second electric push rod 306 to move. When reset to the maximum stroke, turn off the vacuum pump 308, so that the cap adsorbed on the vacuum chuck 309 falls downward. Then, it is received and guided through the material guide hopper 310 for centralized collection. At the same time, through the rubber pad 314, the falling cap can be buffered to avoid bumps. Then start the first electric push rod 304 to reset, so that the vacuum chuck 309 stops above the conveyor belt 301. Start the electric telescopic rod 307 to move the mounting plate 303 downward to adsorb the cap through the vacuum chuck 309, completing the cycle. The automation is relatively high, reducing manual operation and improving the efficiency of edge wrapping the cap.

Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
