Examples
Referring to fig. 1, the present embodiment provides a rolling mechanism 100, where the rolling mechanism 100 provided in the present embodiment is capable of avoiding deformation as much as possible during the process of rolling a pole piece, so as to ensure the thickness uniformity of the pole piece.
The rolling mechanism 100 mainly rolls the pole piece, compacts the coating material on the pole piece, reduces the volume of the pole piece to improve the energy density of the battery, simultaneously makes the contact of active substances and conductive agent particles more compact, improves the electronic conductivity, and can increase the bonding strength of the coating material and the current collector. The rolling mechanism 100 applies pressure to two ends of the press roller when rolling the pole piece, and the middle part of the press roller rolls the pole piece, so that the part of the press roller, where the pole piece is rolled by the press roller, is easy to deform, and the thickness of the pole piece pressed by the roller is uneven.
In order to solve the problem in the prior art, there are various ways, one way is to increase the diameter of the press roller so as to improve the deformation resistance of the press roller, however, the diameter of the press roller cannot be increased limitlessly, the maximum diameter of the press roller in the industry at present can only be 900mm, and the continuous increase of the diameter can increase the difficulty of processing, manufacturing and later maintenance, so that the way can only roll pole pieces with the width smaller than 400 mm.
The other way is to add bending steel at two ends of the press roller, the rolling Qian Yagun generates pre-bending under the pretension force of the bending steel, and the rolling part is straightened under the reaction force of the pole piece when the pole piece is rolled. This approach is then implemented because the bent steel is also disposed at both ends of the press roll, resulting in uneven rolling of the roll on the pole piece.
The press roller is made into an arc shape in a mode, and the rolling part is straightened under the reaction of the pole piece during rolling, but the mode is only suitable for single products, has poor compatibility, needs to customize the arc shape of the surface of the press roller according to the width and the compaction density specification of the pole piece, and cannot be used for mass production.
Therefore, the prior art can not solve the problem that the pole piece appears unevenly in the rolling process, or solve the problem of the uniformity of the pole piece, and cannot solve the universality of the rolling mechanism 100.
