[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-9 The device shown is a power-type single tab forming device, including a processing table 1, a tab strip 101, a tab waste 102, a tab body 103, and a battery body 12. The upper surface of the processing table 1 is provided with a cutting and feeding mechanism 2 for cutting the tab strip 101, and the inside of the processing table 1 is provided with a flipping and conveying mechanism 3 for flipping the battery body 12.

[0023] The cutting and feeding mechanism 2 includes a movable stage 201 slidably connected to the upper surface of the processing table 1.

The output shaft of the double-head motor 216 is fixedly connected to a first gear 217. The upper surface of the processing table 1 is fixedly connected to a gear rack 218.

[0024] Furthermore, after being cut by the laser cutting head 205, the tab waste 102 and the tab body 103 are cut off from above the tab belt 101. The cut tab waste 102 and tab body 103 are then driven by the dual-head motor 216 to move the first gear 217 above the rack 218, thereby moving the moving table 201. When the moving table 201 moves, it moves the tab waste 102 and tab body 103 above the battery body 12. Then, the welding head 11 welds the tab waste 102 to the top of the battery body 12. After welding is completed, the moving table 201... As the platform 201 moves backward, the rotating glass slide 206 moves to both sides of the detached electrode waste 102 and pushes towards the center, pushing the electrode body 103 above the slag discharge port 219. Then, the electrode body 103 is carried into the collection box 215 for collection through the first discharge port 211 and the second discharge port 212. As the moving platform 201 drives the rotating glass slide 206 to continue moving, the rotating glass slide 206 will move to both sides of the electrode belt 101 under the push of the electrode belt 101, thereby achieving the function of cutting and shaping the electrode. At the same time as cutting and welding, it can achieve the function of collecting scrap materials.

[0025] The electrode belt 101, electrode waste 102, and electrode body 103 are arranged above the moving table 201. The push rod 209 is slidably connected to the side surface of the rotating glass slide 206. The slag discharge port 219 and the second discharge port 212 are connected through the first discharge port 211, and the first discharge port 211 is slidably connected to the upper surface of the processing table 1. The collection box 215 is arranged below the second discharge port 212. The first gear 217 and the rack 218 are meshed. The flipping conveyor mechanism 3 includes a first support frame 301 fixedly connected to the lower surface of the processing table 1. A flipping motor 302 is fixedly connected inside the first support frame 301. A rotating table 303 is fixedly connected to the output shaft of the flipping motor 302. A flipping rotating shaft 304 is rotatably connected inside the rotating table 303. The internal rotating shaft of the processing table 1 is rotatably connected to the rotating table 1. A drive shaft 305 is connected to the worktable 1. A conveyor belt 306 is connected to the outer surface of the drive shaft 305. A second support frame 307 is fixedly connected to the lower surface of the worktable 1. A rotating rod 308 is rotatably connected inside the second support frame 307. A second gear 309 is fixedly connected to one end of the rotating rod 308. A drive belt 310 is connected to the outer surface of the fixed plate 208. A third gear 311 is fixedly connected to one end of the outer surface of the drive shaft 305. A rotating table 303 is rotatably connected inside the worktable 1. A positioning block 312 is fixedly connected to the upper surface of the rotating table 303. The battery body 12 is positioned above the conveyor belt 306 and the rotating table 303. The rotating shaft 304 and the rotating rod 308 are connected by the drive belt 310. The second gear 309 and the third gear 311 are meshed together.

[0026] Furthermore, after the battery body 12 is conveyed to the top of the rotating table 303 via the conveyor belt 306 and the flipping rotating shaft 304, the battery body 12 is limited by the positioning block 312. After the electrode waste 102 on one side of the battery body 12 is welded, the rotating table 303 is rotated by starting the flipping motor 302, thereby flipping the battery body 12 and welding the electrode waste 102 on the other side of the battery body 12. At the same time as flipping, the transmission belt 310 is connected to the flipping rotating shaft 304 before and after flipping, thereby achieving the function of conveying the battery body 12 forward via the flipping rotating shaft 304 before or throughout the flipping process.

[0027] The upper surface of the processing table 1 is fixedly connected to a dust-adhesive roller 4, a dust cover 5, and a cooling chamber 6. An observation window 9 is fixedly connected between the dust cover 5 and the cooling chamber 6. A ventilation opening 7 is provided on the side surface of the cooling chamber 6. A cooling fan 8 is fixedly connected inside the cooling chamber 6. A third support frame 10 is fixedly connected above the cooling chamber 6 of the dust cover 5. A welding head 11 is slidably connected to the lower surface of the third support frame 10. The observation window 9 is made of transparent glass. The ventilation opening 7 and the cooling fan 8 form a convection. The welding head 11 is located above the flipping conveyor mechanism 3. The welding head 11 slides under the third support frame 10 and can slide back, forth, left, and right.

[0028] Furthermore, when the battery body 12 is conveyed by the conveyor belt 306, the dust on the surface of the battery body 12 is adhered by the dust-adhesive roller 4 when it passes under the dust-adhesive roller 4. Then, the dust is isolated by the dust cover 5 and the observation window 9 to prevent dust from falling onto the welding point during the welding process. After the welding is completed, the cooling fan 8 set inside the cooling chamber 6 blows air to cool it down. At the same time, the ventilation port 7 can achieve the effect of convection.

[0029] Working principle: First, the battery body 12 is placed above the conveyor belt 306. The tab belt 101 is conveyed to the cutting and unloading mechanism 2 via the fixed table 202 and the conveyor roller 204. Then, the tab waste 102 and the tab body 103 are cut off from above the tab belt 101 by the laser cutting head 205. The cut tab waste 102 and tab body 103 drive the first gear 217 to move above the rack 218 by starting the dual-head motor 216, thereby driving the moving table 201 to move. When the moving table 201 moves... 1. During movement, the electrode waste 102 and electrode body 103 are moved to the top of the battery body 12. Then, the electrode waste 102 is welded to the top of the battery body 12 by the welding head 11. After welding, the moving platform 201 moves backward. When the rotating glass plate 206 moves to the sides detached from the electrode waste 102, it pushes towards the middle, pushing the electrode body 103 above the slag discharge port 219. Then, the electrode body 103 is carried into the collection box 215 through the first discharge port 211 and the second discharge port 212 for collection. As the moving platform 201 drives the rotating glass slide 206 to continue moving, the rotating glass slide 206 will move to both sides of the tab belt 101 under the push of the tab belt 101, thereby achieving the function of tab cutting and shaping. During the cutting and welding process, it can also collect scrap materials. After welding, the cooling fan 8 set inside the cooling chamber 6 blows air to cool it down, and the ventilation vents 7 set up at the same time can achieve the function of convection. At the same time, the battery body 12 is transported to the top of the rotating platform 303 by the conveyor belt 306 and the rotating shaft 304. The battery body 12 is limited by the positioning block 312. After the electrode waste 102 on one side of the battery body 12 is welded, the rotating table 303 is rotated by starting the flipping motor 302, thereby flipping the battery body 12 and welding the electrode waste 102 on the other side of the battery body 12. At the same time as flipping, the transmission belt 310 is connected to the flipping rotating shaft 304 before and after flipping, thereby achieving the function of conveying the battery body 12 forward through the flipping rotating shaft 304 before or always before flipping.
