Description

Technical Field

[0001] The utility model relates to a lithium belt conveying mechanism of a lithium battery full-automatic winding machine, belonging to the field of battery manufacturing. Background Art

[0002] With the continuous advancement of science and technology, lithium batteries are increasingly used in various fields, and higher requirements are placed on the quality and production efficiency of lithium batteries. As one of the core equipment for lithium battery manufacturing, the fully automatic winding machine plays an important role in improving the production efficiency and quality of lithium batteries. As an important part of the fully automatic winding machine, the lithium belt conveyor mechanism has received increasing attention for its research and development background and technical requirements.

[0003] First of all, the lithium belt conveyor mechanism needs to have the characteristics of high precision and high stability. The lithium belt needs to remain flat during the winding process, avoiding wrinkles and bending to ensure the quality of the wound lithium belt. This requires the conveyor mechanism to have high-precision positioning and stable transmission capabilities. At the same time, the conveyor mechanism also needs to adapt to lithium belts of different specifications and materials to meet different production needs.

[0004] However, due to the special characteristics of lithium ribbons, traditional fully automatic winding machines often break lithium ribbons during the battery winding process, making it impossible to meet normal production requirements. In addition, lithium ribbons may wrinkle during the transmission process, causing leakage of the lithium ribbons of the wound battery cells, which brings many unnecessary troubles to related production and seriously affects the production efficiency of the products. Summary of the invention

[0005] According to the problem described in the background, the problem to be solved by the utility model is: a lithium strip conveying mechanism of a fully automatic winding machine for lithium batteries can well ensure the smoothness of the lithium strip conveying before winding, and the correction device can ensure the stability of the lithium strip conveying, thereby improving the qualified rate of battery cell winding.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium tape conveying mechanism of a fully automatic winding machine for lithium batteries is provided, comprising a fixed plate, a connecting plate, a servo motor, a panel group, a roller group, a deviation correction sensor, a bracket and a cylinder, the lithium tape moving path passes through a sliding roller group and a panel group respectively and finally reaches the battery winding traction, the bracket, connecting plate, roller group and panel group are all arranged on one side of the fixed plate, a servo motor is arranged on the other side of the fixed plate, which can control the movement of the roller group, the roller group is located below the bracket, the roller group comprises an upper roller group and a lower roller group, the lower roller group is connected to the cylinder, the panel group is connected to the bracket through a connecting plate, the panel group comprises an upper panel and a lower panel, the lower panel is connected to the cylinder, and the deviation correction sensor is arranged on the upper roller group.

[0007] The roller group is divided into an upper roller group and a lower roller group. The upper roller group is located above the lower roller. The upper roller group includes an upper roller and an upper roller bracket. The lower roller group includes a lower roller and a lower roller bracket. The cylinder is arranged below the lower roller group.

[0008] The bottom of the upper panel and the upper part of the lower panel are both provided with silica gel pads.

[0009] The deviation correction sensor is arranged on one side of the upper roller bracket, and the deviation correction sensor is an infrared sensor.

[0010] The distance between the battery winding traction and the panel group is 20cm to 60cm.

[0011] When the lithium ribbon conveying mechanism of a lithium battery fully automatic winding machine is started, the lithium ribbon is introduced from between two sliding rollers, led out from between two panels, and finally collected by the battery winding traction. During this process, the correction device located on the upper roller group detects the position of the edge of the lithium ribbon through an infrared sensor, feeds back the detected position information to the controller, and then the servo motor on the fixed plate controls the roller group to achieve the purpose of correction; at the same time, the cylinder under the lower roller and the lower panel can open and close it, solving the problem of sagging of the lithium ribbon due to gravity during the transmission process.

[0012] The beneficial effects of the utility model are:

[0013] 1. The roller is equipped with a deviation-correcting induction device to ensure that the lithium belt will not deviate during the transmission process, thereby ensuring that the lithium belt will not leak during winding;

[0014] 2. The tail end of the device adopts the structure of upper and lower panels to fix the lithium ribbon. After the lithium ribbon is wound, it can prevent the lithium ribbon from being affected by the cutting force of the cutter and causing the lithium ribbon to break or extend during the cutting process.

[0015] 3. The lithium belt conveying mechanism can stably convey the lithium belt, ensuring that the tension of the lithium belt is constant during the winding process, effectively avoiding the situation where the lithium belt is loose or too tight, thereby improving the winding accuracy and stability;

[0016] 4. The transmission mechanism adopts a modular design, which is convenient for disassembly and maintenance, reducing maintenance costs and time costs. BRIEF DESCRIPTION OF THE DRAWINGS
