[0021] Example 1: As shown in the accompanying drawings, a nickel strip unwinding device for tab processing includes a mounting frame 1, a plurality of first guide wheels 2, a plurality of second guide wheels 3 and a discharge roller 4, wherein the plurality of first guide wheels 2 are rotatably mounted on the mounting frame 1, the plurality of second guide wheels 3 are rotatably mounted on a side of the mounting frame 1 away from the first guide wheel 2, the discharge roller 4 is rotatably connected to the mounting frame 1, and further includes a tensioning assembly and a drive assembly, the tensioning assembly is used to control the tension of the tab during tab unwinding, and the drive assembly is used to drive the discharge roller 4 to rotate and discharge.

[0022] In this embodiment, specifically, the tensioning assembly includes a rodless cylinder 5, a roller 6, a tension sensor 7 and a first spring 8. The rodless cylinder 5 is connected to the inside of the mounting frame 1. The roller 6 is rotatably connected to the slider of the rodless cylinder 5. The tension sensor 7 is installed in the roller 6. The first spring 8 is connected to the rodless cylinder 5. The rodless cylinder 5 is electrically connected to the tension sensor 7. Furthermore, the driving assembly includes a motor box 9, a driving motor 10, a first transmission assembly 11 and a support assembly. The motor box 9 is installed on the mounting frame 1. The driving motor 10 is installed in the motor box 9. The output shaft of the driving motor 10 is connected to the unloading roller 4 through a coupling. The first transmission assembly 11 is connected between the unloading roller 4 and the first guide wheel 2. The support assembly is used to support the unloading roller 4. Specifically, the support assembly includes a support frame 12, a clamping block 13, a second spring 14 and a centering assembly. The support frame 12 is slidably connected to the mounting frame 1, and the support frame 12 can rotate. The clamping block 13 is slidably connected to the support frame 12. A clamping slot 15 for cooperating with the clamping block 13 is provided in the mounting frame 1. The second spring 14 is connected between the clamping block 13 and the support frame 12. The side of the clamping block 13 close to the mounting frame 1 is an inclined surface. Among them, the centering assembly includes a plurality of third springs 16, a plurality of centering blocks 17 and a plurality of rotating blocks 171. The plurality of third springs 16 are respectively connected to the mounting frame 1 and the support frame 12, the plurality of centering blocks 17 are respectively connected to the adjacent ends of the third springs 16, and the plurality of rotating blocks 171 are respectively rotatably installed on the adjacent centering blocks 17.Specifically, the block 13 is pressed inward, the second spring 14 is compressed, the block 13 leaves the slot 15, and then the support frame 12 is pulled forward so that the block 13 leaves the mounting frame 1, and the block 13 is released. The second spring 14 is reset, driving the block 13 to move outward and reset. The support frame 12 moves forward, driving the third spring 16 and the center block 17 on the front side to move forward and leave the unwinding roller 4. Then, the tab roll to be unwound is placed on the unwinding roller 4, and the support frame is rotated. The support frame 12 is convenient for loading the tab coil, and the operation is simple. Then the support frame 12 is reversed and reset, and then the support frame 12 is pushed to move backward and reset, driving the card block 13, the third spring 16 on the front side and the center block 17 on the front side to move backward and reset. When the card block 13 moves backward and enters the card block 13, under the action of the second spring 14, the card block 13 is stuck in the card slot 15, and then the support frame 12 is limited. The two center blocks 17 cooperate with the rotating block, and the third spring 16 Under the action of , the pole ear roll is clamped and centered, so that the pole ear can be kept in a centered state during unwinding, and the unwinding of the pole ear is guided. Then the drive motor 10 is started, and the output shaft of the drive motor 10 drives the unwinding roller 4 to rotate, and then drives the pole ear roll to rotate and unwind, thereby driving the rotating block to rotate. The rotating block can prevent the pole ear from rubbing against the centering block 17 during rotation and causing wear. Then, the first transmission component 11 drives the first guide wheel 2 to rotate to transport the pole ear. The pole ear passes around the roller 6. Under the action of the tension sensor 7, the tension exerted on the pole ear during transportation can be detected. If the tension is too large, the tension sensor 7 controls the operation of the rodless cylinder, thereby driving the roller 6 to move, so as to achieve the purpose of adjusting the pole ear tension. If the rodless cylinder fails unexpectedly, the first spring 8 can adaptively deform to assist the roller 6 in controlling the tension of the pole ear, so as to avoid accidents of the rodless cylinder during work, which may cause the pole ear to be damaged due to excessive tension.

[0023] Example 2: Based on Example 1, as shown in the accompanying drawings, it further includes a correction component, which is used to limit the deviation of the tab during the unwinding of the tab. Specifically, the correction component includes a rotating shaft 18, a correction wheel 19, a plurality of baffles 20, a bidirectional screw 21, a handle 22, a second transmission component 23 and a third transmission component 24. The rotating shaft 18 is rotatably connected to the mounting frame 1, the correction wheel 19 is connected to the rotating shaft 18, the plurality of baffles 20 are slidably connected to the correction wheel 19, the bidirectional screw 21 is rotatably connected to the correction wheel 19, the plurality of baffles 20 are all threadedly connected to the bidirectional screw 21, the handle 22 is mounted on the bidirectional screw 21, and the handle 22 is detachable. The second transmission component 23 is connected between the rotating shaft 18 and the first guide wheel 2, and the third transmission component 24 is connected between the rotating shaft 18 and the second guide wheel 3.

[0024] In the above technical solution, the tab passes around the correction wheel 19, and then the handle 22 is rotated. The handle 22 drives the bidirectional screw 21 to rotate, and then drives the baffle 20 to move and adjust, so that the baffle 20 clamps and limits the tab. In this way, the tab can be positioned to prevent the tab from shifting during the unwinding process. Moreover, since the position of the baffle 20 can be adjusted, the tabs of different widths can be limited. This has high practicality, improves the stability of the tab unwinding, and avoids affecting subsequent processing.

The present invention is not limited to the above embodiment, and variations in its specific structure are permitted. All variations within the scope of the independent claims of the present invention are within the scope of protection of the present invention.
