Abstract

The invention belongs to the technical field of lithium battery production devices, and particularly relates to a pole piece deviation correction mechanism and method, an encoder device and a lithiumbattery winding machine. The pole piece deviation correction mechanism comprises an installation base, an axial push assembly arranged in the installation base, a movable base arranged at the telescopic end of the axial push assembly, a fixed roller connected to the end portion of the movable base in a rotating manner, a radial push assembly arranged on the end portion of the movable base, and a movable roller arranged at the telescopic end of the radial push assembly; and the radial push assembly can push the movable roller and the fixed roller to cooperate to clamp a pole piece. Compared with the prior art, the pole piece deviation correction mechanism and method, the encoder device and the lithium battery winding machine have the beneficial effects that when deviation correction needs to be conducted, the axial push assembly drives the fixed roller and the movable roller to move in the axial direction at the same time, and therefore deviation correction is achieved; and the type ofstructure is simpler and higher in precision, and pole piece feeding is more convenient.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production equipment, and in particular relates to a pole piece deviation correction mechanism and method, an encoder device and a lithium battery winding machine. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution; the production process of lithium batteries includes pole piece winding, which usually needs to be rectified before winding to prevent the pole piece from being damaged. Winding is carried out under the condition of tape running deviation, which affects product quality. [0003] In the prior art, the deviation correction mechanism before winding in the lithium battery winding machine generally adopts the method of swing correction to carry out the deviation correction process. Such a deviation correction mechanism generally includes a swing s...
