[0002] Power batteries usually refer to high-capacity and high-power batteries used in transportation tools such as electric vehicles and electric bicycles. These batteries need to have high energy density, long cycle life and good safety performance. In power batteries, "tabs" are key components of the battery, responsible for conducting the electrical energy inside the battery to the external circuit.
[0003] In the manufacturing process of power batteries, the cutting and chamfering of tabs are very important steps, which directly affect the reliability and performance of the batteries. By cutting, the dimensions are ensured to be precise to ensure that the tab length meets the design requirements for subsequent welding and assembly; by chamfering the tabs, sharp edges are avoided from piercing the diaphragm or other components during the assembly process, thus preventing internal short circuits in the battery. Currently, the tab forming equipment all adopts a structure of one-time cutting and forming, but the tabs produced by such one-time forming structures have a single shape. When producing tabs of different sizes, the molds need to be replaced, and the mold replacement is not convenient, thus affecting the production efficiency.
[0004] Based on this, it is necessary to design a device that is convenient for automatically cutting and chamfering tabs of different sizes. Summary of the Utility Model

Detailed implementation manners
[0020] The present utility model will be further described below in conjunction with specific embodiments. The schematic embodiments and descriptions of the present utility model are used to explain the present utility model, but not to limit the present utility model.
[0021] Embodiment: An automatic edge cutting and chamfering device for power tabs, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, it includes a base 1, a pay-off reel 2, a cylinder 3, a first roller group 6, a second roller group 7, an arc chamfering cutter 8, an adjusting screw 802, a chamfering support plate 801, a lifting frame 803, a guide rod 804, an equidistant cutter 9 and a cutting plate 901. On the longitudinal wall of the base 1, there are arranged a pay-off reel 2, a cylinder 3, a chamfering support plate 801 and a cutting plate 901. The pay-off reel 2 is used for placing disc-shaped tab ears. The base 1 is provided with a transverse positioning rod 4 for the tab ear to bypass, and the transverse positioning rod 4 positions and guides the movement of the tab ear. On the longitudinal wall of the base 1, there are two guide rods 804. A "π"-shaped lifting frame 803 is slidably connected to the guide rods 804. The lifting frame 803 is arranged above the chamfering support plate 801. The height of the chamfering support plate 801 is higher than that of the positioning rod 4. The movable end of the piston rod of the cylinder 3 is connected to the lifting frame 803. On the bottom left side of the lifting frame 803, there are symmetrically arranged front and rear arc chamfering cutters 8 for chamfering the tab ear. An adjusting screw 802 is rotatably arranged on the lifting frame 803. The front arc chamfering cutter 8 is screwed to the adjusting screw 802. The distance between the front and rear arc chamfering cutters 8 is adjusted by the adjusting screw 802 to adapt to tab ears of different sizes. A limiting plate 805 is screwed to the adjusting screw 802. The limiting plate 805 is slidably matched with the lifting frame 803. The limiting plate 805 is used for effectively limiting tab ears of different sizes, thereby ensuring accurate chamfering and cutting operations on the tab ears. On the transverse front and rear sides of the longitudinal wall of the base 1 with the chamfering support plate 801 as the center, there are respectively arranged a first roller group 6 and a second roller group 7. The ends of the upper and lower rollers in the first roller group 6 and the second roller group 7 are provided with meshing gears. A gap for the tab ear to pass through is left between the upper and lower rollers in the first roller group 6 and the second roller group 7. The function of conveying the tab ear from left to right is realized by the left-right cooperation of the first roller group 6 and the second roller group 7. An equidistant cutter 9 for equidistant cutting of the tab ear after chamfering and cutting is also arranged on the lifting frame 803. The equidistant cutter 9 is arranged above the cutting plate 901 and the equidistant cutter 9 is slidably matched with the right end of the cutting plate 901. The tab ear is cut by the downward movement of the equidistant cutter 9.
[0022] As Figure 1 and Figure 3As shown, it further includes a conveyor belt 10 and a rotating shaft. Two rotating shafts are rotatably arranged in parallel on the longitudinal wall of the base 1. The conveyor belt 10 is wound around between the two rotating shafts. One of the rotating shafts is an electric rotating shaft 1001. When the electric rotating shaft 1001 moves, it drives the other rotating shaft to move through the conveyor belt 10. Transmission belts are provided between the rotating shaft and the second roller group 7, and between the second roller group 7 and the first roller group 6. The rotating shaft 1001 drives the lower roller in the second roller group 7 to rotate through the transmission belt. The lower roller in the second roller group 7 drives the upper roller to move in the reverse direction through gears, so as to realize pulling the tab away from the chamfered support plate 801. The upper roller in the second roller group 7 drives the lower roller in the first roller group 6 to move through the transmission belt, and drives the upper roller in the first roller group 6 to move through the meshing of gears, so as to realize pushing the tab towards the chamfered support plate 801, thus realizing the function of tab conveying.
[0023] The chamfered support plate 801, the cutting plate 901 and the conveyor belt 10 show a trend of gradually decreasing in steps from left to right. This setting facilitates the conveyance of the tabs from left to right.
[0024] As Figure 2 and Figure 4 As shown, a limiting roller 902 is rotatably arranged on the longitudinal wall of the base 1. The limiting roller 902 is arranged above the cutting plate 901 and there is a gap for the tab to pass through between the limiting roller 902 and the cutting plate 901. The limiting roller 902 is used to limit the tab to facilitate the cutting operation of the equal-distance cutting knife 9 on the tab. A transmission belt is provided between the rotating shaft and the limiting roller 902. The rotating shaft drives the limiting roller 902 to rotate through the transmission belt, avoiding the limiting roller 902 pressing on the tab and preventing the tab from moving.
[0025] During use, the disc-shaped tabs are installed on the unwinding reel 2. One end of the tab bypasses the positioning rod 4 and passes through between the first roller group 6, between the second roller group 7, and between the limiting roller 902 and the cutting plate 901. When the electric rotating shaft 1001 works, the electric rotating shaft 1001 drives the limiting roller 902, the first roller group 6, and the second roller group 7 to rotate through the transmission belt. The two rollers in the first roller group 6 cooperate through the gear set to convey the tab towards the chamfered support plate 801. The two rollers in the second roller group 7 cooperate through the gear set to pull the tab away from the chamfered support plate 801, thereby realizing the conveying movement of the tab; the telescopic movement of the piston rod of the cylinder 3 drives the lifting frame 803 to move up and down. The up and down movement of the lifting frame 803 drives the two arc chamfering cutting knives 8 to perform arc chamfering cutting operations on the tab. The equal-distance cutting knife 9 moves down to perform equal-distance cutting operations on the tab on the cutting plate 901, thus realizing the function of automatically cutting and chamfering the tab.
[0026] As Figure 1As shown, a CCD detection device 5 for detecting the tab after cutting is provided on the longitudinal wall of the base 1, and the CCD detection device 5 is arranged above the conveyor belt 10.
[0027] As Figure 1 and Figure 3 shown, it further includes a push plate 11, an electric slide rail 1101, a defective product collection box 12 and a non-defective product collection box 13. Electric slide rails 1101 are symmetrically arranged on the front and rear sides of the longitudinal wall of the base 1 with the CCD detection device 5 as the center. A push plate 11 is slidably connected to the electric slide rails 1101. The push plate 11 is arranged above the conveyor belt 10 and below the CCD detection device 5. A defective product collection box 12 and a non-defective product collection box 13 are arranged on the transverse part of the base 1. The non-defective product collection box 13 is arranged below the conveyor belt 10 and behind its movement track. The CCD detection device 5 is used to detect the tab after chamfering and cutting, and the electric slide rail 1101 is used to drive the push plate 11 to push the defective tab into the defective product collection box 12.
[0028] The cut tab pieces fall onto the conveyor belt 10. The CCD detection device 5 is used to detect the tab pieces falling onto the conveyor belt 10. When a tab piece that does not meet the quality standard is detected, the control unit controls the movement of the electric slide rail 1101, and the electric slide rail 1101 drives the push plate 11 to push forward, thereby pushing the unqualified tab pieces into the defective product collection box 12 for centralized collection. The non-defective tab pieces without defects after being detected by the CCD detection device 5 are conveyed to the non-defective product collection box 13 through the conveyor belt 10 for collection, thereby realizing the detection, screening and automatic collection of the tab pieces.
[0029] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
