Description

Technical Field

[0001] This utility model relates to the lithium battery industry, and in particular to a rotatable alcohol-coated electrode mechanism. Background Technology

[0002] Currently, the lithium battery industry is developing rapidly, with continuous updates and iterations in technology. In pursuit of higher battery performance, a region is cleaned off the surface of the cell electrode for charging and discharging. However, due to the requirements of current electrode manufacturing processes and the limitations of electrode coating technology, after the slurry is coated onto the substrate, it adheres tightly to the substrate after processes such as drying and rolling. It is impossible to quickly and accurately peel off the coating in a certain area. Therefore, lasers are needed to process the electrode to separate the coating layer from the substrate, which facilitates subsequent die-cutting, stacking, and welding of the cell.

[0003] Since the electrode material consists of a coating layer (carbon powder or lithium iron phosphate) and a base layer (copper foil or aluminum foil), which are bonded together with adhesives such as glue, the coating layer needs to be thoroughly cleaned multiple times during laser processing. This process is too time-consuming and results in poor precision. Therefore, the coating layer should be soaked in alcohol first to make it easier for the coating to detach from the base layer, thus reducing the difficulty of laser processing. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a rotatable alcohol-coated electrode mechanism.

[0005] The objective of this invention is achieved through the following technical solution: a rotatable alcohol pressure coating electrode mechanism, comprising a substrate fixing platform and a cylinder. The substrate fixing platform is provided with a rotating shaft fixing seat. The cylinder is rotatably connected to the rotating shaft fixing seat via the rotating shaft. One side of the cylinder is provided with a speed regulating connector and a pressure regulating valve connector. The pressure regulating valve connector is connected to a pressure regulating valve, and the speed regulating connector is connected to a speed regulating valve. The piston rod end of the cylinder is provided with a pressure head mounting block, and a coating pressure head is mounted on the pressure head mounting block. The pressure of this alcohol coating mechanism is adjustable, allowing for adjustment of the downward pressure as needed and the mechanism pressure to be adjusted according to different materials.

[0006] As an improvement of the rotatable alcohol-coated electrode mechanism of this utility model, the rear side of the cylinder is provided with a rotating shaft connecting seat, the middle part of the rotating shaft connecting seat is provided with a rotating shaft connecting hole, one end of the rotating shaft passes through the rotating shaft connecting hole, and a first gasket is provided between the rotating shaft connecting seat and the rotating shaft fixing seat.

[0007] As an improvement of the rotatable alcohol pressure coating electrode mechanism of this utility model, the bottom of the coating head is provided with a plurality of liquid outlet holes at intervals, the front side of the coating head is provided with a liquid injection pipe connection hole, and the coating head is provided with a liquid channel, which is connected to the liquid injection pipe connection hole and the liquid outlet holes.

[0008] As an improvement to the rotatable alcohol-coating electrode mechanism of this utility model, the injection pipe connection hole is inclined.

[0009] As an improvement to the rotatable alcohol-coating electrode mechanism of this invention, the injection pipe connection hole is connected to the injection needle via an injection pipe. The injection needle has graduations for quantitative alcohol injection.

[0010] As an improvement to the rotatable alcohol pressure coating electrode mechanism of this utility model, the bottom of the coating head is covered with at least one layer of lint-free cloth, and alcohol liquid flows out from the outlet hole and wets the lint-free cloth. There are two methods for wetting the lint-free cloth:

[0011] The first method involves injecting alcohol into the coating head through an injection needle when the cylinder is in a vertical position. The alcohol then evenly wets the lint-free cloth through the outlet hole inside the coating head. The injection needle can inject a precise amount of alcohol.

[0012] The second method is to rotate the cylinder 90 degrees to make it horizontal, and then manually apply alcohol to the lint-free cloth to wet it.

[0013] As an improvement of the rotatable alcohol-coated electrode mechanism of this utility model, a handle assembly is provided on one side of the rotating shaft connecting seat. The handle assembly can drive the rotating shaft connecting seat to rotate, thereby driving the cylinder to rotate.

[0014] As an improvement of the rotatable alcohol-coated electrode mechanism of this utility model, the handle assembly includes a spring, a positioning pin, a handle, and a second washer. The spring passes through the positioning pin, the second washer is located between the handle and the rotating shaft connecting seat, one end of the positioning pin is fixed on the rotating shaft connecting seat, and the other end is screwed to the handle.

[0015] As an improvement to the rotatable alcohol-coating electrode mechanism of this utility model, the upper surface of the substrate fixing platform is provided with a positioning reference line. The positioning reference line can be manually adjusted to adjust the alcohol coating position according to the size of the electrode and the required position, adapting to various sizes of electrode for positioning, and then providing a reference edge for laser processing.

[0016] As an improvement to the rotatable alcohol-coating electrode mechanism of this utility model, the cylinder can be manually added after rotation. After rotating 90 degrees, the cylinder is in a horizontal position, and the lint-free cloth rotates to the outside along with the cylinder, making it convenient for manual application of alcohol onto the lint-free cloth.

[0017] The beneficial effects of this utility model are as follows: the pressure of the alcohol coating mechanism of this utility model is adjustable, and the downward pressure can be adjusted according to the needs and the mechanism pressure can be adjusted according to different materials; the pressure of this utility model is controllable, the downward speed is controllable, alcohol can be added directly through the injection needle tube, or alcohol can be added manually by rotating the cylinder, alcohol can be injected in a quantitative manner, and the substrate fixing platform has a positioning reference to adapt to various sizes of electrode sheets for positioning.

[0028] Preferably, the injection pipe connection hole 82 is inclined. The inclination angle of the injection pipe connection hole 82 is 30 degrees, which facilitates the rapid flow of alcohol into the liquid channel and prevents alcohol backflow.

[0029] Preferably, the injection pipe connection hole 82 is connected to the injection needle 85 via the injection pipe 84. The injection needle 85 has graduations for quantitative injection of alcohol.

[0030] Preferably, the bottom of the coating head 8 is covered with at least one layer of cleanroom cloth (not shown), and alcohol liquid flows out from the outlet 81 and wets the cleanroom cloth. There are two methods for wetting the cleanroom cloth:

[0031] The first method involves injecting alcohol into the coating head 8 through the injection needle 85 when the cylinder 2 is in a vertical position. The alcohol then evenly wets the lint-free cloth through the outlet hole 81 inside the coating head 8. The injection needle 85 can inject alcohol in a measured amount.
