Description

Technical Field

[0001] The utility model relates to the technical field of battery pole piece production, in particular to a turret roll-changing automatic tape-connecting and winding mechanism. Background Art

[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, and then the pole piece is cut by a laser die-cutting machine to form tabs. In actual production, in the production mode of forming tabs, for wide-width pole pieces, they are generally cut into two strips and then into four strips, while for narrow-width pole pieces, only two strips are needed. Finally, the cut pole piece material rolls are wound by a single shaft. When changing the roll, it is necessary to stop the machine and manually complete the tape-connecting and roll-changing work, 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.

[0012] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further details the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0013] In order to illustrate the technical solutions described in the present invention, the following will be described through specific embodiments.

[0014] Embodiment

[0015] Please refer to Figure 1 , this embodiment provides a turret roll changing automatic tape splicing and winding mechanism, including a turret winding assembly 1 and an automatic tape splicing assembly 2. After the tabs of the tabbed sheet are formed, the turret winding assembly 1 winds the tabbed sheet material roll, and the automatic tape splicing assembly 2 is arranged on one side of the turret winding assembly 1 to realize automatic roll changing, tape splicing and unwinding between two winding shafts.

[0016] Specifically, the turret rewinding assembly 1 includes a rotating device 11, a turntable 12, a rotating axis 13, a first rewinding shaft 14, a second rewinding shaft 15, a bracket 16, a first auxiliary support structure 17, a second auxiliary support structure 18, and a material pushing mechanism 19. The rotating axis 13 is rotatably arranged on the rotating device 11 through the turntable 12. The first rewinding shaft 14 and the second rewinding shaft 15 are rotatably arranged on the turntable 12 and are relatively located on both sides of the rotating axis 13. The first auxiliary support structure 17 and the second auxiliary support structure 18 are rotatably arranged on the bracket 16 and respectively correspond to the shaft ends of the first rewinding shaft 14 and the second rewinding shaft 15. The first auxiliary support structure 17 and the second auxiliary support structure 18 are provided with support openings adapted to the shaft ends of the first rewinding shaft 14 and the second rewinding shaft 15. The material pushing mechanism 19 is arranged below the second rewinding shaft 15. The automatic tape splicing assembly 2 includes a swing rod mechanism 21, a pressure roller group 22, a cutter 23, and a return cylinder. The pressure roller group 22, the cutter 223, and the return cylinder are all arranged on the swing rod mechanism 21. The cutter 23 is located between the pressure roller group 22. The return cylinder is located at one end of the cutter 23, and its cylinder shaft is connected to the cutter 23.

[0017] Its working principle is as follows: When the first rewinding shaft 14 reaches the upper limit and needs to change the roll, the equipment starts to decelerate. The second rewinding shaft 15 with double-sided tape rotates counterclockwise 180° around the rotating axis and exchanges positions with the first rewinding shaft 14. The first auxiliary support structure 17 and the second auxiliary support structure 18 rotate along with the first rewinding shaft 14 and the second rewinding shaft 15 to support the shaft ends and ensure the bearing capacity of the roll. After the tail stock pole piece on the first rewinding shaft 14 is pressed tightly on the second rewinding shaft 15 by the pressure roller group 22 on the swing rod mechanism 21, the cutter 23 rotates through the return cylinder to cut off the tail stock pole piece. The second rewinding shaft 15 starts to rotate clockwise automatically. When the tape on the second rewinding shaft 15 adheres to the pole piece on the first rewinding shaft 14, the pole piece on the second rewinding shaft 15 is connected to the pole piece on the first rewinding shaft 14 to achieve automatic roll change. At the same time, the swing rod mechanism 21 rebounds and resets, and the equipment starts to accelerate and unwind for normal production. At this time, the first rewinding shaft 14 after exchanging positions can discharge the pole roll on it through the material pushing mechanism 19 below.

[0018] In summary, the turret roll change automatic tape splicing and rewinding mechanism can achieve automatic roll change and tape splicing without stopping the machine, greatly improving work efficiency, avoiding waste caused by manual operation to products, and ensuring the consistency of product quality.

[0019] The above is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
