Description

Technical Field

[0001] The utility model relates to the field of battery pole piece unwinding, in particular to a battery pole piece unwinding deviation correction device. Background Art

[0002] With the increasing attention paid to energy and environmental protection issues around the world, new energy electric vehicles that save energy and reduce emissions have gradually received widespread attention from various countries. Lithium-ion power batteries have the advantages of high specific energy, long life, and no memory, and have become the first choice for clean electric vehicle power sources. The lithium battery production process is relatively complex and can be divided into three tasks: pole piece production, battery cell unit production, and battery assembly. The pole piece coating process is the primary process for pole piece manufacturing and is the basis for ensuring the quality of the pole piece. Since the battery coating machine pole piece production line is relatively long, generally more than 100 meters, the pole piece must pass through the drive roller, guide roller and other links, and there may be uneven tape rolls, tension changes, disturbances, etc., which may cause the substrate to easily deviate, thereby affecting the quality of the battery cell. Therefore, research on the deviation correction of battery pole pieces is of great significance. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a battery pole piece unwinding and deviation correction device, which can stably correct the deviation during the pole piece unwinding process.

[0004] In order to solve the above problems, a battery pole piece unwinding and correction device is adopted, which includes:

[0005] An unwinding roller, which unwinds the pole piece;

[0006] A coating roller, which coats the electrode sheet;

[0007] A guide wheel, through which the pole piece is connected to the coating roller, and a vertical spacing between the guide wheel and the coating roller enables the pole piece to be in a horizontal state between the guide wheel and the coating roller;

[0008] An adjustment frame, on which the unwinding roller and the guide wheel are mounted;

[0009] A bracket, which is vertically arranged on the side plate of the adjustment frame and is located between the coating wheel and the guide wheel;

[0010] A photoelectric sensor is disposed laterally on the upper end of the bracket and is located on the side of the pole piece to detect the position of the pole piece;

[0011] A guide rail, which is laterally arranged below the adjustment frame;

[0012] a base plate disposed below the guide rail;

[0013] The cylinder has a telescopic end fixedly connected to one side of the adjustment frame;

[0014] A flange, which is fixed to the base plate;

[0015] The motor is mounted on the flange and connected to the cylinder to drive it to work;

[0016] The controller receives feedback from the photoelectric sensor and controls the operation of the motor.

[0017] With such a structure, the position change of the edge line of the pole piece is detected by a sensor installed on the side of the pole piece, such as a distance sensor, etc., and the change in distance is read to reflect the position change, etc. If the read value remains unchanged, if it has always been the reference value, there is no deviation, and if the read value changes, there is a deviation. If the set read value becomes larger, it is a positive deviation, and if the read value becomes smaller, it is set as a negative deviation, etc. The deviation value is calculated by the read value and the reference value, and the corresponding value and direction of the cylinder that needs to be extended and retracted are obtained through positive and negative, so as to achieve the effect of adjusting the deviation. During the reading period, the pole piece needs to remain horizontal and is always detected by the photoelectric sensor to prevent data loss.

[0018] As a further improvement of the utility model, a U-shaped support is provided at the lower end of the bracket, and the U-shaped support is clamped on the side plate of the adjustment frame.

[0019] With such a structure, the U-shaped support is easy to snap on and move.

[0020] As a further improvement of the utility model, the first support plate on the adjustment frame for mounting the unwinding roller is lower than the second support plate for mounting the guide wheel, so that the overall height of the guide wheel is higher than the unwinding roller.

[0021] With such a structure, the height difference facilitates tensioning of the pole piece.

[0022] As a further improvement of the utility model, the photoelectric sensor and the motor are connected to the controller by wires.

[0023] With such a structure, wired access can be achieved, data reading effect is good, and data loss can be avoided.

[0024] As a further improvement of the utility model, leveling bolts are arranged at the four corners of the base plate, and a universal level bubble is installed on the base plate.

[0025] With this structure, the substrate can be leveled in advance to improve measurement accuracy.

[0026] The utility model can stably correct deviation during the unwinding process of the pole piece. BRIEF DESCRIPTION OF THE DRAWINGS
