The invention discloses a pole piece rolling device. The pole piece rolling device is used for rolling a pole piece and comprises a main shaft, first loop rings and second loop rings; the first loop rings and the second loop rings are detachably installed on the main shaft in a sleeving manner; a plurality of first loop rings are arranged; at least one second loop ring is arranged; and the outer wall surfaces of the first loop rings and the second loop rings form a rolling surface. According to the pole piece rolling device disclosed by the invention, the main shaft is provided with the firstloop rings and the second loop rings; the outer wall surfaces of the first loop rings and the second loop rings form the rolling surface for rolling the pole piece; moreover, the first loop rings andthe second loop rings are detachably installed on the main shaft in a sleeving manner so that the size of the rolling surface can be regulated according to the size of the pole piece, and thus the rolling effect of the pole piece rolling device is better, and the application range of the pole piece rolling device is wider.
Description
technical field [0001] The invention relates to the technical field of manufacturing battery-related components, in particular to a pole piece rolling device. Background technique [0002] As the main energy storage component of electric vehicles, lithium-ion batteries have been vigorously developed with the development of electric vehicles. As an important part of the lithium battery, the pole piece plays an important role in improving the performance of the lithium battery. In order to improve the coating efficiency of the pole piece, a coating area and a blank area are set on the pole piece, and cutting is performed after coating is completed. [0003] However, since the number and width of coating areas on different pole pieces may be different, different rolling devices need to be used for different pole pieces, so that the versatility of the rolling device is relatively low. Contents of the invention [0004] In view of this, one of the objectives of the present in...
