The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Please refer to Figures 1 to 5A tab conveying and cutting mechanism includes a feeding tray 100, a conveying channel 200, a driving unit 300, a positioning unit 400, a cutting unit 500 and a conveying unit 600. The feeding tray 100 and the cutting unit 500 are respectively located at two ends of the conveying channel 200, two groups of driving units 300 are arranged in the middle of the conveying channel 200, and the positioning unit 400 is located between the two groups of driving units 300. The feeding tray 100 is used to install the tab coil, and the driving unit 300 drives the tab to be conveyed in the conveying channel 200. The cutting unit 500 is used to cut the conveyed tab, and when cutting, the positioning unit 400 presses down and positions the conveyed tab, and the conveying unit 600 conveys the cut tab.

[0030] Specifically, in the present embodiment, when the pole lug is conveyed and cut, the pole lug coil is mounted on the feeding tray 100, and the starting end of the pole lug is inserted into the conveying channel 200, and the driving unit 300 drives the pole lug in the conveying channel 200 to be conveyed. During the conveying process, the pole lug first passes through the positioning unit 400 and another group of driving units 300 to the cutting unit 500. After the driving unit 300 drives the pole lug to convey the pole lug of the set length, the driving unit 300 stops conveying, and the positioning unit 400 moves downward to press the pole lug in the conveying channel 200. After pressing, the cutting unit 500 cuts off the output pole lug of the set length, and the cut pole lug is then sucked and conveyed by the conveying unit 600, thereby finally realizing the automatic conveying, automatic cutting and automatic conveying of the pole lug, thereby improving the automation degree of the pole lug conveying and cutting mechanism, and improving the cutting efficiency of the pole lug, while ensuring the consistency of the pole lug cutting and improving its quality.

[0031] The tab conveying and cutting mechanism in this embodiment is arranged on the pole piece production line and cooperates with the pole piece conveying jig. The handling unit 600 is a PPU robot, which adsorbs the cut tabs through the PPU robot and then places them in the jig to cooperate with the pole piece.

[0032] See also Figure 2 and Figure 4 In order to realize automatic transportation of the tabs, the driving unit 300 in this embodiment includes an upper roller 310, a lower roller 320, a driving motor 330 and a lifting cylinder 340. The upper roller 310 and the lower roller 320 are arranged up and down and are respectively placed in the conveying channel 200. The driving motor 330 is located outside the conveying channel 200 and is connected to the lower roller 320. The lifting cylinder 340 is connected to the upper roller 310 through the lifting frame 350. The driving motor 330 can drive the lower roller 320 to rotate, and the lifting cylinder 340 can drive the upper roller 310 to rise and fall.

[0033] After the starting end of the tab is inserted into the conveying channel 200, the lifting cylinder 340 drives the lifting frame 350 to move downward. When the lifting frame 350 moves, it drives the upper roller 310 to move downward, and cooperates with the lower roller 320 to roll the tab in the conveying channel 200. The driving motor 330 then drives the lower roller 320 to rotate, so that the tab is conveyed by the rotation of the lower roller 320 and the upper roller 310. After the tab is output from the conveying channel 200 by a set length, the lifting cylinder 340 drives the lifting frame 350 to reset and rise upward. The lifting frame 350 drives the upper roller 310 to rise, so that the conveying of the tab is stopped by the separation of the upper roller 310 and the lower roller 320. After the tab of the set length conveyed is cut, the upper roller 310 moves downward through the lifting cylinder 340 and cooperates with the lower roller 320, and so on in a cycle to realize the automatic conveying of the tab.

[0034] Please refer to Figure 4 , in order to avoid the displacement of the tab when it is cut, in this embodiment, the positioning unit 400 includes a positioning fixing plate 410, a positioning cylinder 420 and a positioning block 430. The positioning cylinder 420 is installed on the positioning fixing plate 410, and the positioning block 430 is connected to the positioning cylinder 420. The positioning cylinder 420 can drive the positioning block 430 to lift and penetrate through the top of the conveying channel 200 to press and fix the tab.

[0035] When the driving unit 300 drives the tab in the conveying channel 200 to output a set length, the driving unit 400 stops conveying. At this time, the positioning cylinder 420 is started and drives the positioning block 430 to move downward. The positioning block 430 penetrates through the top of the conveying channel 200 and presses and fixes the tab. After pressing and fixing, the cutting unit 500 can cut the output tab into segments. By pressing and fixing the tab through the positioning unit 400, the displacement of the tab during cutting can be avoided, thereby improving the cutting quality of the tab.

[0036] Please refer to Figures 4 to 6 , in order to realize the automatic cutting of the tab, the cutting unit 500 in this embodiment includes a cutter 510, a receiving platform 520, a limiting block 530 and a cutting cylinder 540. The cutter 510 is located above the end of the conveying channel 200. The receiving platform 520 is connected to the end of the conveying channel 200 through a tension spring 550, and a slide rail 560 is arranged at the bottom of the receiving platform 520. The limiting block 530 acts on the receiving platform 520. The cutting cylinder 540 is connected to the cutter 510 and the limiting block 530 respectively and drives the cutter 510 and the limiting block 530 to lift. A limiting wheel 521 is arranged on one side of the receiving platform 520, and an inclined limiting arm 531 is arranged on the side of the limiting block 530. The limiting wheel 521 moves along the limiting arm 531. The receiving platform 520 is also provided with vacuum adsorption holes 522.

[0037] Specifically, when cutting, the driving unit 300 outputs the tab with a set length, and then the positioning unit 400 presses and fixes the tab. At this time, the cutting cylinder 540 drives the cutter 510 and the limit block 530 to move downward. When the limit block 530 moves downward, its limit arm 531 releases the restriction on the limit wheel 521 on one side of the receiving platform 520. Under the pulling force of the tension spring 550, the receiving platform 520 moves along the slide rail 560 towards the conveying channel 200. When it moves to the set position, the cutter 510 also moves down to the set position and cuts the output tab. The cut tab is adsorbed by the vacuum adsorption holes 522 of the receiving platform 520 to prevent the cut tab from shifting, facilitating the subsequent handling by the handling unit 600. After the tab is cut, the cutting cylinder 540 drives the cutter 510 and the limit block 530 to move upward and reset. When the limit block 530 moves upward, its limit arm 531 acts on the limit wheel 521 again to press it, causing the receiving platform 520 to move backward and reset and pulling the tension spring 550. The positioning unit 400 releases the tab in the conveying channel 200, and the driving unit 300 drives the tab to be conveyed again, thus circularly and automatically cutting the tab, improving the cutting efficiency of the tab. And through the operation of the cutting cylinder 540, the linkage between the cutter 510 and the receiving platform 520 can be realized, thereby improving the intelligent level of the cutting unit 500.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry can smoothly implement the present invention according to what is shown in the description drawings and the above description; however, any equivalent changes such as slight modifications, decorations and evolutions made by those skilled in this professional field without departing from the technical solution of the present invention and using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
