Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, in particular to a nickel strip stamping mechanism. Background Art

[0002] New energy batteries have been widely used due to their advantages of energy saving, environmental protection and low carbon. Among them, lithium batteries are the most widely used. From base stations to laptops and mobile phones, lithium batteries are indispensable. Lithium batteries need to be made through winding, liquid injection, sealing, formation and other processes. The two poles of the battery are aluminum electrodes and nickel electrodes respectively, but in actual production, both poles are required to be nickel electrodes, so we need to convert the current aluminum electrodes into nickel electrodes. We will use welding needles to weld the nickel electrodes to lithium batteries. Before welding, the nickel electrodes are on the nickel strip coil. When welding, the nickel electrodes are first punched out of the nickel strip. However, the nickel electrodes on the nickel strips sometimes have defective units. If they are accidentally welded on the battery, the entire battery will be judged as unqualified. Therefore, it is necessary to first detect the nickel electrodes on the nickel strips, screen out the unqualified nickel electrode units in advance and punch them out. In order to improve the accuracy of stamping and avoid damage to the adjacent qualified nickel electrodes during the stamping process, it is necessary to develop a nickel strip stamping mechanism to achieve the effect of accurately stamping defective units.

[0021] After the nickel strip is inspected for appearance in the previous process, the nickel strip is conveyed to the left on three sets of guide rollers 4 according to a certain step distance under the traction of the traction component 3. The three sets of guide rollers 4 can ensure the stability of the nickel strip transmission. When a defective unit is detected on the nickel strip and conveyed to the bottom of the stamping component 2, the first clamping component 5 and the second clamping component 6 clamp the two ends of the nickel strip, which is conducive to the subsequent stamping of the defective unit without causing the nickel strip to deviate, thereby improving the stamping accuracy. Before stamping, the Y-axis adjustment device 21 has been pre-adjusted. The front and rear positions of the punch component 28 are adjusted to accommodate nickel strips of different sizes. During stamping, the X-axis drive device 22 drives the horizontal vertical plate 23 to move left and right, so that the punch component 28 corresponds to the top of the defective unit. The first lifting motor 25 drives the lifting vertical plate 24 to rise, thereby raising the stamping base 27. The upper end surface of the stamping base 27 contacts the nickel strip. The second lifting motor 26 drives the punch component 28 to descend and punch the defective unit. The defective unit falls into the recovery box 29 through the blanking through hole on the stamping base 27. The advantage of this design is that it can stably punch out defective units on nickel strips with high precision.

[0022] The Y-axis adjustment device 21 includes a mounting base 211, a Y-axis slide 212, a slide plate 213, a rotating bracket 214, a movable bracket 215, an adjusting screw 216 and a knob 217. The mounting base 211 is fixed on the second mounting stand 1, the Y-axis slide 212 is fixed above the mounting base 211, the slide plate 213 is slidably connected to the Y-axis slide 212, and the slide plate 213 can slide along the front and rear directions on the Y-axis slide 212.

[0023] Before punching, the front and rear positions of the punch component 28 have been pre-adjusted by the Y-axis adjustment device 21. The knob 217 is turned to rotate the adjustment screw 216 forward or reversely, so that the movable bracket 215 drives the slide plate 213 to move forward and backward on the Y-axis slide 212, thereby adjusting the punch component 28 to a suitable position.

[0024] The punch component 28 includes a guide component 281, a punch fixing seat 282, a pressure plate connecting frame 283, an elastic pressure plate 284 and a cutter 285. The guide component 281 is fixed on the lifting vertical plate 24 and corresponds to the top of the punching base 27. The punch fixing seat 282 is fixed to the power output end of the second lifting motor 26 and is slidably connected to the guide component 281. The second lifting motor 26 drives the punch fixing seat 282 to move up and down. The rear end of the pressure plate connecting frame 283 is fixed on the transverse vertical plate 23. The left and right ends of the elastic pressure plate 284 are elastically connected to the front end of the pressure plate connecting frame 283. The elastic pressure plate 284 elastically expands and contracts in the vertical direction on the pressure plate connecting frame 283. A vertical punching through hole is opened in the middle of the elastic pressure plate 284, and the punching through hole corresponds to the top of the blanking through hole. The upper end of the cutter 285 is fixed on the punch fixing seat 282, and the lower end corresponds to the top of the punching through hole. The lower end of the cutter 285 is opened with a V-shaped groove opening downward.

[0025] During stamping, the X-axis drive device 22 drives the transverse vertical plate 23 to move left and right, so that the punch component 28 corresponds to the top of the defective unit, and the first lifting motor 25 drives the lifting vertical plate 24 to rise, thereby raising the stamping base 27. The upper end surface of the stamping base 27 contacts the nickel strip and continues to rise. The upper end surface of the nickel strip contacts the elastic pressure plate 284 and causes it to rise a certain distance. The stamping base 27 and the elastic pressure plate 284 fix the nickel strip. Then, the second lifting motor 26 drives the punch fixing seat 282 to move downward along the guide component 281, so that the cutter 285 cuts the defective unit, and the defective unit falls into the recovery box 29 through the blanking through hole on the stamping base 27. The lower end of the cutter 285 is provided with a V-groove with an opening downward, which can make the defective unit shrink inward when the defective unit is cut off, thereby avoiding the cut defective unit from being stuck in the blanking through hole, thereby improving the stability of stamping.

[0026] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
