Description

Technical Field

[0001] The present invention relates to the field of lithium battery production, and in particular to a two-position double-sided gluing device, battery cell winding equipment, a production line and a gluing method. Background Art

[0002] Among current lithium battery core-making equipment, winders offer the widest coverage and highest production efficiency. However, compared to bare cells manufactured through lamination and other core-making processes, the bare cells produced by these machines have several disadvantages and risks. For example, during subsequent pre-pressing, cold / hot pressing, and shaping processes, the first and second folds of the cathode electrode (based on aluminum foil) are subject to a high risk of fracture at the inner circle. This results in a low core-making yield. To prevent this from causing NGs, winder designs typically incorporate a cathode protective adhesive application process before winding. This involves applying a layer of protective adhesive to the A and B surfaces of the cathode electrode (at two locations on both the front and back sides), with four strips applied (i.e., two locations on each side).

[0003] In the existing technology, there are two main technical directions for applying protective glue to the cathode. The first one is to prepare the protective glue on the AB surface of the first fold and the second fold in two steps, that is, the first step is to prepare the glue and apply the glue on the AB surface of the first fold, and the second step is to prepare the glue and apply the glue on the AB surface of the second fold. The technical advantages of this solution are: saving the space occupied by the cathode protective glue assembly and simplifying the component design cost. The disadvantage is: increasing the process time of the winding machine occupied by the process of applying the protective glue, resulting in limited improvement in the production rhythm of the winding machine; the second one is to complete the preparation and application of the protective glue on the AB surface of the first fold and the second fold at one time. The technical advantages of this solution are: greatly reducing the process time of the winding machine occupied by the process of applying the protective glue, improving the production rhythm of the winding machine, and applying four layers of glue at the same time, with good consistency. The disadvantage is: due to structural and design limitations, the component is large in size, occupying the already tight space of the winding machine, and the design cost is high, which increases the design cost of the winding machine, resulting in weakened market competitiveness.

[0004] In summary, in view of the many technical defects of the two existing cathode protection adhesive technologies: the process takes a long time, the components occupy a large space and volume, the design structure is complex, and the design cost is high, it is urgent to design a new technical solution to solve the existing technical defects.

The two-position double-sided glue pulling mechanism 1 includes four groups of glue pulling components 11 and glue pulling drive components 12. The four groups of glue pulling components 11 are all driven by the same group of glue pulling drive components 12 and can pull glue synchronously. The tape unwinding mechanism 4 is used to unwind the tape. The two-position double-sided glue pulling mechanism 1 is used to pull the unwound tape to a preset length. The tape pressing mechanism 7 is used to press the tape that has been pulled to a preset length. The punching and lifting mechanism 6 and the tape punching mechanism 5 are used to cooperate to cut the tape. The glue taking and patting mechanism 2 is used to take away the cut tape and stick the tape on the corresponding position of the electrode. The glue taking and patting mechanism 2 has four groups. The four groups of glue taking and patting mechanisms 2 are used to perform double-sided glue sticking on the electrodes at two workstations.

[0043] Specifically, the tape unwinding mechanism 4 has four groups, which are convenient for unwinding four tapes. The four tapes are used to stick on the double-sided gluing positions of the two gluing positions of the electrode respectively. The tape unwinding mechanism 4 includes a tape unwinding material disk, a tape shortage detection device, and a tape unwinding drive device; the tape punching mechanism 5, the tape punching and lifting mechanism 6 and the tape pressing mechanism 7 all have four groups.

[0044] It also includes a tape missing detection mechanism 9 and a tape buffer mechanism 8. The tape missing detection mechanism 9 is used to detect whether the tape is missing at the preset gluing position of the electrode. The tape buffer mechanism 8 has four groups and is used to buffer four tapes respectively. The tape buffer mechanism 8 includes a tape buffer roller.

[0045] In the specific implementation of the present invention, four sets of tape unwinding mechanisms 4 unwind four pieces of tape. After the four sets of adhesive drawing components 11 pull the tape to a preset length, the tape pressing mechanism 7 compresses the tape, the tape punching and lifting mechanism 6 lifts the tape, and the tape punching mechanism 5 cuts the tape, completing the adhesive preparation process. After the adhesive preparation is completed, the four sets of adhesive removal and adhesive taping mechanisms are used to simultaneously apply the four pieces of tape to both sides of the two workstations of the electrode.

[0046] In this technical solution, since the four groups of glue pulling components 11 are all driven by the same group of glue pulling drive components 12 and can pull glue synchronously, two-position double-sided synchronous glue pulling can be achieved.

The action rhythm is fast, which can improve production efficiency.

[0049] In addition, the third glue-taking and glue-padding mechanism 203 and the fourth glue-taking and glue-padding mechanism 204 are both arranged on the frame via the distance-adjusting guide rail 3. The third glue-taking and glue-padding mechanism 203 and the fourth glue-taking and glue-padding mechanism 204 can be driven by the distance-adjusting driving device to move on the distance-adjusting guide rail 3 to adjust the distance between the first glue-taking and glue-padding module and the second glue-taking and glue-padding module. In specific implementation, the distance between the first glue-taking and glue-padding module and the second glue-taking and glue-padding module can be adjusted according to different battery cell models and sizes to adapt to different size requirements, thereby having the advantages of high application flexibility and strong versatility.

The nut of the glue pulling screw nut pair 123 is provided with a glue pulling connecting plate 125, and the glue pulling connecting plate 125 is connected to the glue pulling sliding seat 112. The glue pulling drive motor 122 can drive the glue pulling sliding seat 112 and the glue pulling claw 114 to slide on the glue pulling guide rail 111 through the glue pulling screw nut pair 123 and the glue pulling connecting plate 125 to realize the glue pulling function; the glue pulling guide rail 111 has four, and each glue pulling guide rail 111 is provided with a group of glue pulling components 11, and the glue pulling sliding seats 112 of the four groups of glue pulling components 11 are fixedly connected to the nuts of the glue pulling screw nut pair 123 through the same glue pulling connecting plate 125, and a number of glue pulling limit sensors 126 are provided on the glue pulling mechanism mounting frame 121, and a glue pulling limit sensing piece 127 cooperating with the glue pulling limit sensor 126 is directly or indirectly installed on the glue pulling connecting plate 125.
