Description

Technical Field

[0001] The utility model belongs to the field of battery core production and processing equipment, and particularly relates to a non-free state flipping mechanism for a diaphragm end. Background Art

[0002] Lithium-ion battery cells are formed by stacking multiple layers of battery electrodes with separators between adjacent electrodes. After each round of stacking, the separators must be cut to produce individual cells. The cut separators are then pulled back onto the stacking table for the next cell. However, the separators are thin and soft, and after being cut, they droop freely, making them difficult to accurately pull onto the stacking table. Therefore, a yaw mechanism is required to correct and position the separators during the pulling process.

[0003] Chinese patent CN220856637U (publication date: April 26, 2024) discloses a diaphragm pulling assembly, which relates to the technical field of battery cell production equipment. It includes: a stacking table; a diaphragm driving mechanism that can move horizontally above the stacking table to pull the diaphragm onto the stacking table for Z-shaped lamination to form a stacked battery cell; a cutter mechanism for cutting the diaphragm after the suction plate absorbs the diaphragm; a diaphragm pulling mechanism, which is arranged on one side of the stacking table and includes a suction plate and a fixed frame; the suction plate is arranged on the fixed frame for horizontal and vertical movement, and the fixed frame drives the suction plate in a linear motion in the horizontal direction to move the suction plate closer to or away from the stacking table. When the suction plate approaches the stacking table, the suction surface adsorbing the diaphragm is in contact with the side wall of the stacking table to fix the diaphragm. This utility model can quickly position and place the diaphragm, shortening the time and achieving high precision.

[0004] Chinese patent CN221564825U (publication date: August 20, 2024) discloses an automatic diaphragm positioning mechanism, comprising a positioning bracket, a spreading assembly, a stripping assembly, and a correction assembly. The correction assembly is mounted on the positioning bracket and is used to propel air toward the diaphragm, rotating it until it is positioned. This utility model achieves automated positioning, replacing manual operation, ensuring production quality, reducing production time, and improving production efficiency.

[0005] Chinese patent CN115632168A (publication date: January 20, 2023) discloses a lamination device, including a lamination mechanism, a swing roller mechanism, a diaphragm positioning mechanism, and a cutting mechanism. After the battery cells are stacked, the diaphragm positioning mechanism fixes the diaphragm between the output end of the swing roller mechanism and the lamination table to a first adsorption surface, and the cutting mechanism cuts the diaphragm. Because the diaphragm is adsorbed and fixed by the first adsorption surface before and after cutting, and the free section formed after the diaphragm is cut can be pulled to the lamination table under the drive of the first holding member, no correction is required after the first layer of diaphragm is laid.

[0006] The traditional deflection mechanism blows the diaphragm to the vicinity of the robot by blowing air, and then the robot pulls the diaphragm to the diaphragm correction plate for correction. This deflection mechanism has the following shortcomings: First, the air blowing method cannot completely guarantee that the diaphragm can be blown into place every time, and the failure rate is high; second, the diaphragm is in a free state during the blowing process, and the airflow is uneven, which can easily cause diaphragm wrinkles, and the diaphragm and the corners of the stacking table will be scratched, causing powder loss or damage, which is easy to cause defects; finally, the diaphragm is in a free state throughout the process, and the position deviation is large, which can easily cause low correction accuracy. Utility Model Content

[0007] In order to solve the above technical problems, the purpose of the present utility model is to provide a non-free state flipping mechanism for the end of the diaphragm, which realizes the non-free state flipping of the diaphragm and improves the accuracy of the diaphragm correction, thereby saving correction time and improving work efficiency.

[0008] A non-free state flipping mechanism for the end of a diaphragm, comprising a diaphragm transverse movement manipulator, an auxiliary traction manipulator, an operating platform and a diaphragm;

[0009] The diaphragm transverse movement manipulator is located above the operating platform;

[0011] The auxiliary traction manipulator is located below the operating platform.

[0012] Furthermore, the diaphragm transverse movement robot includes an offset guide rail and a passing rod;

[0013] Furthermore, the offset guide rail is arranged in parallel with the operating platform;

[0014] Furthermore, the passing rod is located below the offset guide rail and can move on the offset guide rail;

[0015] Furthermore, the diaphragm transverse movement robot clamps the diaphragm through a rod;

[0016] Furthermore, the operating platform includes a lamination table, a diaphragm deviation correction plate and a diaphragm suction plate;

[0019] Furthermore, the auxiliary traction manipulator adopts a telescopic manipulator for traction of the diaphragm suction plate;

[0023] 2. The utility model realizes the non-free flipping of the diaphragm by coordinating the actions of the diaphragm transverse movement manipulator, the auxiliary traction manipulator and the diaphragm suction plate, thereby avoiding the problem of diaphragm wrinkles caused by uneven blowing airflow and the problem of scratches and damages that may be caused during the diaphragm backblowing process, and improving the accuracy of diaphragm correction.

[0064] Example 3

[0065] Based on Examples 1-2, this example is a method for using a non-free state flipping mechanism at the end of a diaphragm.

[0066] Please refer to Figure 2 , a schematic diagram of the working process of a non-free state flipping mechanism at the end of the diaphragm. Figure 2 (a) is a schematic diagram of the initial state of the correction process of the non-free state flipping mechanism at the end of the diaphragm. As shown in the figure, the diaphragm transverse movement robot 1 is on the right side of the stacking table 3 when the battery cell is unloading;
