Description

technical field [0001] The invention relates to the technical field of lithium battery automatic winding equipment, in particular to a fully automatic battery winding deviation correction equipment. Background technique [0002] At present, the base material of lithium battery is getting thinner and thinner. The traditional lithium battery winding equipment uses the diaphragm and the electrode material to be fed together. The frictional force and the pressure of the clamping top roller cylinder are passively pulled for wrapping and winding. During this process, the diaphragm material will be subjected to a pulling force that is about several times the set tension, which will cause deformation of the wound cell and further cause the inner layer Pole piece discount. In addition, the distance between the deviation correction mechanism and the winding mechanism of traditional lithium battery winding equipment is generally 550mm to 750mm. A large distance between the two will ca...
