The invention relates to the technical field of battery preparation, in particular to a winding device and a battery preparation machine. The winding device includes a shifting mechanism and a needle winding mechanism. The shifting mechanism is used to transfer the cell to the next station. The shifting mechanism is provided with a winding space. The needle winding mechanism includes a needle winding assembly, which can be stretched out , so as to be located in the winding space, and rotate in the winding space to form a battery core, and the winding needle assembly can be retracted to release the battery core into the winding space. The above-mentioned winding device is provided with a displacement mechanism to transfer the battery core in the winding space to the next station, so that a set of needle rolling mechanism can be set to rotate in the winding space to wind the diaphragm and pole pieces to form the battery core Compared with the method of setting up two sets of needle winding mechanisms and transferring them to the next station by turning over, the winding space of the needle winding assembly is larger, so as to avoid the production size of the battery cell product being limited due to the limited winding space of the needle winding assembly. restrictions, so that it can meet the winding needs of large-size batteries.
Description
technical field [0001] The invention relates to the technical field of battery preparation, in particular to a winding device and a battery preparation machine. Background technique [0002] In recent years, as people pay more and more attention to the living environment and energy crisis, the research, development and application of new energy technologies have developed rapidly. As one of the major industries in the field of new energy technology other than lithium batteries, nickel batteries have the advantages of good high and low temperature performance and good safety performance. They have made great progress and have been widely used in electric vehicles, electric vehicles and other fields. At present, the most commonly used nickel battery is the nickel metal hydride battery. [0003] In the production process of nickel-metal hydride batteries, winding separators, positive and negative electrodes and other materials to form battery cores is one of the important prod...
