[0058] Please refer to Figures 1-12The working process of the general tab cutting forming machine is as follows: the tab 10 on the pole piece 9 is placed on the suction plate 27 of the pole piece transfer mechanism 2, the suction plate 27 tightly sucks the pole piece 9 and the tab 10 placed thereon, the suction plate 27 of the pole piece transfer mechanism 2 and the pole piece 9 and the tab 10 thereon move left and right under the drive of the first servo motor 21 to transfer the pole piece 9 and the tab 10 and position the cutting width of the left and right parts of the tab 10, respectively; the suction plate 27 and the pole piece 9 and the tab 10 thereon move forward and backward under the drive of the second servo motor 204 to position the cutting height or longitudinal length of the tab 10; the suction plate 27 and the pole piece 9 and the tab 10 thereon are raised under the drive of the first cylinder 25 to be raised and transferred when the tab 10 is placed in front of the cutting assembly 56; after the tab 10 is transferred to the predetermined cutting position, the suction plate 27 and the pole piece 9 and the tab 10 thereon are lowered under the drive of the first cylinder 25 to place the tab 10 on the cutting assembly 56 of the tab cutting mechanism 5, the cutting assembly 56 supports the tab 10, the pressure switch 205 detects the vacuum negative pressure of the suction plate 27 tightly sucking the pole piece 9, the structure design of the pole piece transfer mechanism 2 not only realizes automatic cutting and positioning of the tab 10, but also realizes different cutting requirements by cutting and positioning the pole piece 9 without changing the cutter die, which solves the problem of high cost of lithium battery tab research and production due to the need to change different cutter dies for different specifications and different cutting requirements.

[0059] The second cylinder 74 and the fourth cylinder 704 of the cleaning mechanism 7 cooperate to position the brush 703 before cleaning the cutting assembly 55 and the cutting assembly 56, and the third cylinder 79 drives the brush 703 to move to clean the adhered particles of the cutting assembly 55 and the cutting assembly 56.

[0060] The cutting driving mechanism 53 drives the cutting assembly 55 to cut the tab 10 through the cutting transmission assembly 54, the lower cutter die 562 of the cutting assembly 56 bears the tab 10, the fifth cylinder 62 of the tab pressing mechanism 6 drives the second pressing plate 65 to press and fix the tab 9, so as to prevent the tab 9 from being warped during the cutting of the tab 10 and avoid the displacement of the tab 10 during the cutting, improve the smoothness and efficiency of the cutting of the tab 10, and ensure the high precision and good cutting effect of the cutting of the tab 10.

The upper cutter die 555 and the lower cutter die 562 cooperate to automatically cut the tab 10. The air pipe joint 557 is connected with the air pipe to supply air to the upper cutter die 555. The high-pressure gas is sprayed out through the air blowing hole 556 of the upper cutter die 555 to blow the waste generated during the cutting of the tab 10, so that the upper cutter die 555 can automatically remove the waste. This greatly improves the effect and quality of the cutting and forming of the tab 10, and effectively solves the problem that the current tab cutting is affected by the phenomenon that the cutting die is easily contaminated with metal slag particles generated during the cutting process, which causes difficult or no separation of the tab cutting and the burr on the edge of the tab.

[0061] When the differential head 88 of the color detection mechanism 8 is twisted, the detector moving plate 83 can drive the color detector 85 to move forward and backward on the two detector positioning straight line sliding modules 82 to position the color detector 85. This can adjust the position of the color detector 85 to detect the tab 10, so that it is suitable for detecting tabs 10 of different specifications, and has the advantages of high universality and high detection accuracy of the color detector 85.

[0062] The overall structure design can adjust the cutting width, cutting length or cutting height, and lifting and transferring, so that it can cut tabs of different specifications without changing different specifications of the cutter die (i.e. the upper cutter die and the lower cutter die), has the advantages of high universality and greatly reduces the cost of lithium battery tab research and production.
