[0002] Laser die-cutting is widely used in the tab forming of battery pole pieces due to its characteristics of small cutting burrs, low maintenance cost, and large flexibility. In the existing pole piece forming, the pole piece material roll is usually unwound by a single shaft, and then the pole piece is cut by a laser die-cutting machine to form tabs. When the roll needs to be changed, the machine needs to be stopped and the tape connecting and roll changing work is manually completed, which greatly affects the work efficiency, and manual operation will cause certain waste to the product and also has a certain impact on the product quality.

[0013] In order to make the purpose, technical solutions and advantages of the present utility model more clear, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0014] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.
[0015] Embodiment
[0016] Please refer to Figure 1 , this embodiment provides a turret roll changing and automatic tape splicing unwinding mechanism, including a turret unwinding assembly 1 and an automatic tape splicing assembly 2. The pole piece is unwound through the turret unwinding assembly 1, and the automatic tape splicing assembly 2 is arranged on one side of the turret unwinding assembly 1 to realize automatic roll changing, tape splicing and unwinding between two unwinding shafts.
[0017] Specifically, in combination with Figure 2As shown in the figure, the turret unwind assembly 1 includes a first bracket 11, a rotating axis 12, a first rotating shaft seat 13, a second rotating shaft seat 14, a first unwind reel 15 and a second unwind reel 16. One end of the rotating axis 12 is rotatably connected to the first bracket 11 through the first rotating shaft seat 13, and the other end of the rotating axis 12 is rotatably connected to the first bracket 11 through the second rotating shaft seat 14. The first unwind reel 15 and the second unwind reel 16 are oppositely arranged on both sides of the rotating axis 11. One end of the first unwind reel 15 and the second unwind reel 16 is rotatably connected to the first rotating shaft seat 13, and the other end of the first unwind reel 15 and the second unwind reel 16 is rotatably connected to the second rotating shaft seat 14.
[0018] Specifically, in combination with Figure 3 As shown in the figure, the automatic tape splicing assembly 2 includes a second bracket 21, a swing rod mechanism 22, a pressure roller group 23, a cutter 24 and a return cylinder 25. One end of the swing rod mechanism 22 is rotatably connected to the second bracket 21. The pressure roller group 23, the cutter 24 and the return cylinder 25 are all arranged on the swing rod mechanism 22. The cutter 24 is located between the pressure roller groups 23, and the return cylinder 25 is located at one end of the cutter 24, and its cylinder shaft is connected to the cutter 24.
[0019] Its working principle is as follows: When the first unwind reel 15 reaches the lower limit and needs to change the reel, the equipment starts to decelerate. The second unwind reel 16 with double-sided tape winds counterclockwise around the rotating axis by 180° and exchanges positions with the first unwind reel 15. After the tail stock pole piece on the first unwind reel 15 is pressed tightly on the second unwind reel 16 by the pressure roller group 23 on the swing rod mechanism 22, the cutter 24 rotates through the return cylinder 25 to cut off the tail stock pole piece. The second unwind reel 16 starts to rotate counterclockwise automatically. When the tape on the second unwind reel 16 adheres to the tail stock of the first unwind reel 15, the pole piece on the second unwind reel 16 is connected to the pole piece on the first unwind reel 15 to realize automatic reel change. At the same time, the swing rod mechanism 22 springs back to reset, and the equipment starts to accelerate and unwind.
[0020] In summary, the turret reel-changing automatic tape splicing and unwinding mechanism can realize automatic reel change and tape splicing without stopping the machine, greatly improving the working efficiency, avoiding waste caused by manual operation to the products, and ensuring the consistency of product quality.
[0021] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
