Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery winding machines, in particular to a glue-laminating and tail-cutting mechanism of a battery winding machine. Background Art

[0002] Existing lithium-ion battery cells are primarily made by winding positive and negative electrodes separated by a separator. During production, the positive and negative electrodes need to be glued together after winding to prevent the wound battery from becoming loose.

[0003] As disclosed in the Chinese patent document with application number 202120134109.X, a gluing device for the end of a lithium battery winding machine includes a glue preparation device, a glue pressing and adsorption mechanism arranged at one end of the glue preparation device, a glue cutting mechanism arranged between the glue preparation device and the glue pressing and adsorption mechanism, and a gluing mechanism arranged near the glue preparation device; the glue preparation device also includes a glue opening mechanism and a glue feeding mechanism. The utility model separates the glue feeding mechanism and the glue pressing and adsorption mechanism, and moves the cut tape to the gluing station through the glue pressing and adsorption mechanism so that the gluing mechanism can remove the tape and complete the gluing. It is simple and efficient. At the same time, the glue sticking rocker and the rotating module cooperate to drive the glue roller module to attach the tape to the surface of the battery cell. The work efficiency is high, and the overall design is reasonable, the structure is compact, and the practicability is strong.

[0004] Another example is the lithium battery glue unloading mechanism and lithium battery winding device disclosed in the Chinese patent document with application number 202123336631.5. The lithium battery glue unloading mechanism is arranged on a frame plate on which a winding mechanism is installed, and includes: a slide movably arranged on the frame plate; a slide drive unit that drives the slide to move between a first position and a second position; a glue application component arranged on the slide, and the glue application component applies glue to the battery cells on the winding mechanism when the slide moves to the first position; and a unloading component arranged on the slide, and the unloading component removes the battery cells on the winding mechanism when the slide moves to the second position. The two processes of applying the termination glue and unloading the battery cells in the winding core preparation process can be completed by a set of mechanisms. The structure is compact and can reduce the installation space of the equipment.

[0005] Another example is a super small battery cell glue finishing mechanism of a lithium battery film winding machine disclosed in the Chinese patent document with application number 202120500878.7, which includes a front plate, a tape unwinding roller, a guide roller, a rear plate, a lifting cylinder, a glue preparation clamp cylinder, a movable clamp, a fixed clamp, a clamp mounting seat and a glue pressing and cutting assembly. The glue preparation clamp cylinder and the clamp mounting seat are installed in front of the front plate. The piston rod of the glue preparation clamp cylinder is hinged to the middle of the movable clamp, and the lower part of the movable clamp is hinged. On the clip mounting base, a fixed clip is installed on the side of the clip mounting base. After the tape is unwound from the tape unwinding roller, it is guided by multiple guide rollers into between the movable clip and the fixed clip. The glue preparation clip cylinder drives the upper end of the movable clip to clamp the tape. The lifting cylinder drives the front plate to rise close to the battery cell at the gluing station. The glue pressing and cutting assembly is located above the front plate to press and cut the tape to complete the gluing finishing process. The structural design is compact and reasonable, and it can effectively realize the finishing gluing of ultra-small battery cells to meet production needs.

[0006] In the prior art, when applying glue, the entire device is placed close to the battery cell (after the positive and negative electrode strips are wound) to apply glue. The overall movement method can easily make the structure unstable and the ends of the tape can easily become misaligned with the battery cell. Summary of the Invention

[0022] Beneficial effects of the utility model:

[0023] The utility model relates to a battery winding machine for gluing and finishing unloading mechanism. When in use, the tape roll is placed on the tape unwinding roller. The tape passes through the tape guide roller, the tape pulling roller, and the tape feeding module in sequence to reach the taping module. When it is necessary to pull out the tape of a preset length, the tape pressing module presses the tape, and the tape pulling roller moves to drive the tape unwinding roller to rotate. The tape feeding module clamps the tape and moves it toward the taping module. The lower taping roller first pushes the end of the tape next to the battery cell, and then the upper taping roller pushes the end of the tape to fit the battery cell and presses against the outside of the battery cell to rotate together. During this period, the core-pressing roller presses against the battery cell to prevent the battery cell from becoming fluffy and spreading. After the battery cell winding and gluing are completed, the tape cutting module cuts the tape to complete the finishing of the taping of the battery cell. The taped battery cell can then be taken out through the unloading module.

[0024] Compared with the existing technology, the glue application is achieved by relying on the upper and lower glue rollers of the taping module to approach the battery cells. There is no need to move the entire back panel closer, the structure is more stable, the energy consumption is lower, the alignment of the tape and the battery cells is easier to control, and the quality of the final glue application is improved.
