[0023] Example

[0024] See also Figure 1-Figure 4 The utility model provides a lithium battery tab processing device, including a base 100 and a positioning assembly 200.

[0025] The positioning assembly 200 is installed on the base 100, and the lithium battery tab is placed on the base 100. The tab can be fixed by the positioning assembly 200, thereby reducing the possibility of displacement of the lithium battery tab during punching.

[0026] See also Figure 1-Figure 2A support frame 110 is installed on the surface of the base 100, and a telescopic member 120 is installed in the support frame 110. The movable end of the telescopic member 120 is connected to a punching member 130. In a specific implementation, the support frame 110 can be used to support the telescopic member 120 and the punching member 130, and the lithium battery tab is placed on the surface of the base 100. By starting the telescopic member 120, the punching member 130 can be moved downward, which is beneficial to punching the lithium battery tab. It should be noted that the telescopic member 120 can be made of rubber or silicone.

[0027] In this embodiment, a support leg 140 is installed on the surface of the base 100, and a plurality of support legs 140 are provided; the punching member 130 includes a connecting block 131 and a punching knife 132, the connecting block 131 is connected to the movable end of the telescopic member 120, and the punching knife 132 is fixedly connected to the lower surface of the connecting block 131, and a notch corresponding to the punching knife 132 is opened on the surface of the base 100. In specific implementation, by starting the telescopic member 120, its movable end drives the connecting block 131 to move downward, and then drives the punching knife 132 to move downward, which is beneficial to the punching processing of the lithium battery ear. Here, a notch corresponding to the punching knife 132 is opened on the surface of the base 100 to reduce the possibility of collision between the punching knife 132 and the base 100.

[0028] See also Figure 1-Figure 4 The positioning assembly 200 includes a motor 210 and a double-headed screw 220. The motor 210 is mounted on the surface of the base 100, and the output shaft of the motor 210 is transmission-connected to the double-headed screw 220. The double-headed screw 220 is rotationally mounted in the base 100, and the surfaces of the two threaded sections of the double-headed screw 220 are threadedly sleeved with a fixing plate 230. The fixing plate 230 is slidingly connected to the surface of the base 100, and a rotating member 240 is threadedly connected to the surface of the fixing plate 230. The lower end of the rotating member 240 is rotationally connected to a positioning block 250, and the positioning block 250 is in contact with the surface of the fixing plate 230. In a specific implementation, the fixing plate 230 is a U-shaped plate. Start the motor 210 so that its output shaft drives the double-headed screw 220 to rotate, thereby driving the two fixed plates 230 on the surface of the double-headed screw 220 to move relative to or away from each other along the surface of the base 100, thereby reducing the possibility that the movement trajectory will be offset during the movement of the two fixed plates 230, and at the same time facilitating the positioning of lithium battery tabs of different sizes. Then, by rotating the rotating part 240, it drives the positioning block 250 to move downward along the surface of the fixed plate 230, which is beneficial to the stability of the positioning block 250 during the movement, and the positioning block 250 will position the tab, thereby reducing the possibility that the lithium battery tab will be easily displaced during the punching process.

[0029] In this embodiment, the output shaft of the motor 210 is connected to the first bevel gear 211, and the first bevel gear 211 is transmission-connected to the double-headed screw 220; a cavity 150 is opened in the base 100, and the double-headed screw 220 and the first bevel gear 211 are both located in the cavity 150. In a specific implementation, the double-headed screw 220 and the first bevel gear 211 are arranged in the cavity 150 to reduce the possibility of damage to the double-headed screw 220 and the first bevel gear 211 due to external influences.

[0030] The surface of the double-headed screw 220 is connected with a second bevel gear 221, and the second bevel gear 221 is meshed with the first bevel gear 211; the surface of the base 100 is provided with a slide groove corresponding to the fixed plate 230, and the lower surface of the fixed plate 230 is connected with a moving block 231, and the moving block 231 is threadedly sleeved on the surface of the threaded segment of the double-headed screw 220, and the moving block 231 is in contact with the inner wall of the cavity 150. In the specific implementation, by starting the motor 210, its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 will drive the second bevel gear 221 to rotate, and then drive the double-headed screw 220 to rotate, so that the two moving blocks 231 move relative to or away from each other along the inner wall of the cavity 150, which is beneficial to the stability of the moving block 231 during the movement process, and the two moving blocks 231 will drive the fixed plate 230 connected thereto to move along the inner wall of the slide groove, which is beneficial to the positioning of lithium battery pole ears of different sizes.

[0031] The rotating member 240 includes a screw rod 241, a limit block 242 and a rotating block 243. The screw rod 241 is threadedly connected to the fixed plate 230, and the two ends of the screw rod 241 are fixedly connected to the limit block 242 and the rotating block 243 respectively. The limit block 242 is rotatably connected to the inside of the positioning block 250, and a protective pad is connected to the lower surface of the positioning block 250. In a specific implementation, the screw rod 241 and the limit block 242 can be driven to rotate by rotating the rotating block 243. Since the screw rod 241 will rotate and move downward, it will drive the positioning block 250 to move downward and contact the pole ear, which is beneficial to fix the lithium battery pole ear. Here, the limit block 242 is rotatably connected to the positioning block 250, which can reduce the possibility that the limit block 242 will drive the positioning block 250 to rotate.

[0032] Specifically, the working principle of the lithium battery ear processing equipment is as follows: when in use, the lithium battery ear is placed on the surface of the base 100, and the motor 210 is started so that its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 drives the second bevel gear 221 to rotate, thereby driving the double-headed screw 220 to rotate, so that the two moving blocks 231 move relative to or opposite to each other along the inner wall of the cavity 150, which is beneficial to the stability of the two moving blocks 231 during the movement process, and the moving block 231 drives the fixed plate 230 to move, so that the two fixed plates 230 are moved toward the lithium battery ear. The ear is close to the battery, and the rotating block 243 is rotated to drive the screw rod 241 to rotate, which can drive the limit block 242 to rotate and move downward, and then drive the positioning block 250 to move downward along the surface of the fixed plate 230, which is beneficial to the stability of the positioning block 250 when moving, and the positioning block 250 will press the ear, reducing the possibility of displacement of the lithium battery ear during the punching process, and then start the telescopic part 120 on the surface of the support frame 110, so that its movable end drives the connecting block 131 and the punching knife 132 to move downward, which is beneficial to the punching of the lithium battery ear.
