DETAILED DESCRIPTION

[0017] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0018] As one aspect of the utility model, a lithium battery winding machine glue sticking device is provided, including: a mounting plate 1, a first tape material tray assembly 2, a second tape material tray assembly 3, a third tape material tray assembly 4, a fourth tape material tray assembly 5, a first flip-type glue sticking mechanism 6, a second flip-type glue sticking mechanism 7, and four glue preparation components 8, wherein the first tape material tray assembly 2, the second tape material tray assembly 3, the third tape material tray assembly 4, and the fourth tape material tray assembly 5 are sequentially arranged on the mounting plate 1 from top to bottom, and the four glue preparation components 8 are respectively connected to the first tape material tray assembly 2, the second tape material tray assembly 3, the third tape material tray assembly 4, and the fourth tape material tray assembly 5. The material tray assembly 4 and the fourth tape material tray assembly 5 are arranged in one-to-one correspondence, the first flip-type gluing mechanism 6 corresponds to the position setting between the first tape material tray assembly 2 and the second tape material tray assembly 3, the second flip-type gluing mechanism 7 corresponds to the position setting between the third tape material tray assembly 4 and the fourth tape material tray assembly 5, and a pole piece transmission mechanism 9 running perpendicular to the mounting plate 1 is arranged between the second tape material tray assembly 3 and the third tape material tray assembly 4, and the rotation axis of the first flip-type gluing mechanism 6 and the second flip-type gluing mechanism 7 is perpendicular to the running direction of the pole piece transmission mechanism 9.

[0019] Preferably, the first tape material tray assembly 2, the second tape material tray assembly 3, the third tape material tray assembly 4, and the fourth tape material tray assembly 5 have the same structure, and the first tape material tray assembly 2 includes a material reel 10, a counterweight 11, a linear guide 12, a fixed guide roller 13, and a movable guide roller 14, the linear guide 12 is arranged at the output side of the material reel 10, the movable guide roller 14 is arranged on the counterweight 11, the counterweight 11 is arranged on the linear guide 12, the fixed guide roller 13 is installed on the mounting plate 1, and the fixed guide roller 13 is arranged on at least one side of the linear guide 12. Preferably, the counterweight 11 is replaced by the first cylinder 31.

[0020] Among them, the material reel 10 is used to store the tape 28, and the rotation resistance is controlled by the magnetic damper at the tail end. The tape passes around the fixed guide roller 13 and the movable guide roller 14, and a certain length of the tape 28 is cached through the counterweight block 11 or the first cylinder 31 to realize a conventional rubber pedaling mechanism. Its basic principle is a pair of movable pulley components, which is only used for material tape transmission, called cache. The cylinder telescopic stroke is equal to 1 / 2 of the cache length, which meets the longest requirement of the process tape.

[0021] Preferably, the glue preparation assembly 8 includes a driving unit 15, a cutter 16, a cutter cylinder 17, a top block 18, a top block cylinder 19, a glue pulling block 20, a glue pressing roller 21, a roller cylinder 22 and a linear guide 23. The linear guide 23 is arranged on the mounting plate 1, and the cutter cylinder 17 and the top block cylinder 19 are both arranged at the first end of the linear guide 23. The driving unit 15 drives the glue pulling block 20 and the roller cylinder 22 to move along the linear guide 23. The roller cylinder 22 is arranged above the glue pulling block 20. The cutter 16 is connected to the output end of the cutter cylinder 17, the top block 18 is connected to the output end of the top block cylinder 19, and the glue pressing roller 21 is connected to the output end of the roller cylinder 22.

[0022] Among them, the glue preparation component 8 is fixed on the mounting plate 1, and is arranged up and down and on the front and back corresponding to the four material reels 10. It is driven by four sets of independent driving parts 15 (for example, a single-axis robotic arm, a servo single-axis robotic arm). The distance between the glue pressing roller 21 and the glue pulling block 20 is driven by the roller cylinder 22. The minimum distance is required to clamp the tape. The driving part 15 drives the glue pulling block 20 and the glue pressing roller 21 to move along the linear guide rail 23, so that the tape 28 on the corresponding material reel 10 can be pulled out as required, and the moving distance is the required tape length; the glue cutting mechanism has two cylinders, the top block cylinder 19 drives the top block 18 to press the tape 28, and the cutter cylinder 17 retracts and drives the cutter 16 to cut the tape 28.

[0023] Preferably, the first flip-type gluing mechanism 6 and the second flip-type gluing mechanism 7 have the same structure, and the first flip-type gluing mechanism 6 includes an upper suction cup 24, a lower suction cup 25, a cylinder 26 and a servo motor 27, and the servo motor 27 is connected to the mounting plate 1, and the servo motor 27 drives two oppositely arranged cylinders 26 to connect, one cylinder 26 is connected to the upper suction cup 24, and the other cylinder 26 is connected to the lower suction cup 25.

[0024] Among them, the flip-type glue sticking mechanism is used to stick the tape 28 of the glue preparation component on the passing pole piece 29. When working, the upper suction cup 24 and the lower suction cup 25 are driven by two independent cylinders 26 and guided by two slide rails respectively. Among them, the cylinder 26 retracts to the glue preparation posture and extends to the glue sticking posture. The upper suction cup 24 and the lower suction cup 25 use negative pressure vacuum to adsorb and release the tape 28 cut off by the glue preparation component through negative pressure and positive pressure. In addition, driven by the servo motor 27, the upper suction cup 24 and the lower suction cup 25 can rotate around the rotating shaft. After the tape 28 on the current suction cup is pasted, the servo motor 27 drives the upper suction cup 24 and the lower suction cup 25 to rotate 180°, so that the suction cup that is not used and still has tape is rotated to the pole piece 29, so that continuous glue can be applied. Preferably, in order to avoid pipeline entanglement, an electrical slip ring can be added.

[0025] In the above technical scheme, the gluing device of the lithium battery winding machine in the utility model has four different material reels 10, which can be loaded with tapes 28 of different thicknesses and widths, and can be pasted with four types of tapes 28. During operation, the length pulled out by the corresponding glue preparation component according to the process requirements is transferred and pasted to the pole piece 29 through the expansion and contraction of the cylinder built in the first flip-type gluing mechanism 6 and the second flip-type gluing mechanism 7, so that the tape 28 is finally pasted with the pole piece 29. In addition, through the flipping of the first flip-type gluing mechanism 6 and the second flip-type gluing mechanism 7, different tapes of the upper and lower suction cups can be cyclically pasted on the pole piece 29.

[0026] Due to the adoption of the above technical scheme, the four different material reels 10 in the utility model share a mounting plate 1, saving equipment space and cost, and adopting a flip-type gluing mechanism, four different tapes can be glued in the same work station. When the current tape is being glued, the preparation of another tape can be carried out at the same time, which improves efficiency; when the tapes on the same side are the same, the tape can be replaced without stopping the machine to achieve the roll change, which reduces the time for changing the tape.

[0027] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
