Problems solved by technology
[0004] In order to make up for the deficiencies in the prior art, the present invention proposes a lithium battery pole piece coating machine. The present invention is mainly used to solve the problems caused by the use of The quality of the pole piece is poor, sometimes there will be some protrusions on the pole piece and the thickness of the two sides of the pole piece is not equal, resulting in uneven coating of the pole piece and different coating thickness after coating. The problem

The invention belongs to the technical field of a coating machine and particularly relates to a lithium battery pole piece coating machine. The lithium battery pole piece coating machine comprises a machine body; the inner surface, on the back side inner wall, of the machine body is rotatably connected with a first rolling rod through a rotating shaft; the left side, on the inner surface of the machine body, of the first rolling rod is fixedly connected with a first baffle; the left side, on the inner wall surface of the machine body, of the first baffle is fixedly connected with an annular plate; the left side, on the inner surface of the machine body, of the annular plate is rotatably connected with rotating rollers arranged uniformly through a rotating shaft; the left side, on the innersurface of the machine body, of a second baffle is rotatably connected with pressing rollers arranged uniformly through a rotating shaft; the left side, on the inner surface of the machine body, of the pressing roller is rotatably connected with coating heads arranged uniformly through a rotating shaft; the left sides, on the inner surface of the machine body, of the coating heads are rotatably connected with a second rolling rod through a rotating shaft; and the lithium battery pole piece coating machine is mainly used for solving the problems that the pole piece is coated non-uniformly andthe coating thickness is not consistent after the pole piece is coated due to poor quality of the used pole piece when existing lithium battery pole piece coating machines perform coating.
Description
technical field [0001] The invention belongs to the technical field of coating machines, in particular to a lithium battery pole piece coating 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. Lithium batteries were first used in pacemakers. Lithium batteries have the advantages of extremely low self-discharge rate and flat discharge voltage, so that the pacemaker implanted in the human body can operate for a long time without recharging. With the development of science and technology, lithium batteries have become the mainstream now. The coating is lithium One of the most important technological processes of ion batteries, coating is to evenly coat the positive electrode slurry or negative electrode slurry required for the manufacture of lithium ion batteries on the substrate. At present, the positive electrode substrate is alum...
