Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a battery pole piece coating machine. Background Art

[0002] The battery electrode coating machine is a key equipment used to coat electrode materials in the battery production process. Its main function is to evenly coat the electrode material on the current collector to form an electrode sheet. The traditional coating technology mainly uses a wet coating method, that is, the electrode material is dissolved or dispersed in a solvent, and then the solution is evenly coated on the current collector through a coating device.

[0003] However, wet coating requires the use of a large amount of organic solvents, which not only increases production costs, but also the volatilization of solvents during the production process will pollute the environment, affecting the green and environmental protection of production. Secondly, the electrode after wet coating needs to be dried to remove the solvent, which increases the complexity and energy consumption of the production process. Finally, the volatilization of solvents in the wet coating process may also cause changes in the composition of the electrode material, affecting the performance and quality of the battery.

[0004] In response to the above shortcomings, dry coating technology came into being. Dry coating does not require the use of solvents, but mechanically coats the electrode material directly on the current collector, thus avoiding the use and volatilization of solvents. However, the existing dry coating equipment still has some problems during use, such as low coating uniformity, unstable coating process, and difficulty in removing excess materials, which seriously affect the application effect and promotion of dry coating technology.

[0005] Therefore, those skilled in the art have proposed a battery electrode coating machine. Utility Model Content

[0006] The utility model discloses a battery pole piece coating machine, aiming to solve the technical problems existing in the background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A battery electrode coating machine comprises a shell, wherein two groups of rollers are symmetrically rotatably connected inside the shell, the roller core of each group of rollers extends to the outside of the shell and is fixedly connected to a connecting gear, the corresponding two connecting gears are meshingly connected, an electrode sheet is movably connected between the two groups of rollers, two sliding rods are symmetrically slidably connected to the shell, a top plate is fixedly connected between the tops of the sliding rods, the bottoms of the sliding rods extend to the inside of the shell, and an upper contact plate is fixedly connected between the bottoms of the two sliding rods.

[0009] The driving motor and the rotating plate drive the driving gear and the rotating plate to rotate. The driving gear and the rotating plate are semi-gear structures, because when the driving gear and the rotating plate move to a certain angle, the sliding rod and the rotating plate can rebound.

[0010] In a preferred solution, a plane is provided on one of the sliding rods and teeth are provided on the plane at equal intervals, a driving motor is fixedly connected to the top of the shell, a driving gear is fixedly connected to the output end of the driving motor, and the driving gear is meshed with the teeth.

[0011] The spring and the rotating plate can provide rebound power for the sliding rod and the rotating plate.

[0012] In a preferred solution, a spring is sleeved on the outer side of the sliding rod and between the housing and the upper contact plate.

[0013] Through such an arrangement, the moving block, the rotating plate, and the rotating plate can slide on the smooth rod, the rotating plate, and the rotating plate.

[0014] In a preferred solution, two fixing plates are symmetrically fixedly connected to the bottom of the inner wall of the shell, two polished rods are symmetrically fixedly connected between the two fixing plates, and two moving blocks are symmetrically slidably connected between the outer sides of the polished rods.

[0015] By rotating the bidirectional screw rod, the rotating plate and the rotating plate, the moving block, the rotating plate and the rotating plate can be driven to move in opposite directions.

[0016] In a preferred solution, a bidirectional screw is rotatably connected between the two fixed plates, one end of the bidirectional screw extends to the outside of one of the fixed plates and is fixedly connected to an adjustment disk, and the bidirectional screw is threadedly connected to the moving block.

[0017] The movement of the moving block, the rotating plate, and the rotating plate drives the connecting plate, the rotating plate, and the rotating plate to rotate. During the rotation process, the connecting plate, the rotating plate, and the rotating plate cooperate with the rotating plate, the rotating plate, and the rotating plate, thereby driving the lower contact plate, the rotating plate, and the rotating plate to rise and fall, so that the lower contact plate, the rotating plate, and the rotating plate are in contact with the electrode sheet and the rotating plate.

[0018] In a preferred solution, the tops of the moving blocks are all rotatably connected to connecting plates, the tops of the connecting plates are all rotatably connected to rotating plates, and a lower contact plate is fixedly connected between the tops of the two rotating plates.

[0019] By setting a scraper, the materials on the surface of the electrode sheet and the rotating plate can be evenly scraped.

[0020] In a preferred solution, scrapers are provided on both the upper contact plate and the lower contact plate, and the scrapers are in contact with the electrode sheets.

[0021] The notches facilitate scraping and collecting the scraped material.

[0022] The battery pole piece coating machine provided by the utility model has the following advantages:

[0023] 1. By driving the gear and the rotating plate to rotate at a fixed point, the sliding rod and the rotating plate are driven to move downward, so that the upper contact plate, the rotating plate and the lower contact plate, the rotating plate, the rotating plate and the electrode sheet and the rotating plate are in contact, thereby achieving the coating work on the electrode sheet and the rotating plate. This design can achieve the coating operation efficiently and accurately, and improve the operating efficiency and accuracy of the equipment;

[0024] 2. The sliding rod and the rotating plate are repeatedly lifted and lowered through the driving gear and the rotating plate, which in turn drives the upper contact plate and the rotating plate to repeatedly lift and lower, thereby hitting the electrode sheet and the rotating plate, thereby shaking off the excess material on the electrode sheet and the rotating plate. This design not only improves the efficiency of material removal, but also can adapt to the use requirements under different working conditions, broadening the application range of the equipment.
