Technical Field

The invention relates to the technical field of coating equipment, in particular to cathode electrophoretic coating equipment.

Background

With the rapid development of national economy, the development of new materials and new energy fields is also showing a sudden and violent momentum. Among them, batteries are widely used in life and industrial production as a cross focus in the fields of new materials and new energy. Due to the limitation of the calculation result of the saturation theory, the mainstream development trends of special soft-pack type and box type battery units in the battery industry at present focus on improving the cathode, the electrolyte and the like of the battery. According to data of 2021-2026 year development trend of the global and Chinese cathode electrophoretic coating industry and competition strategy research reports, the problems of the current battery cathode in production and use are mainly that the battery cathode is worn too fast, and particularly the whole aging rate of the battery cathode working in high-strength and high-corrosion electrolyte medium is fast. In order to eliminate the problem, various scientific research and production units mainly adopt the technical scheme of electrophoretic coating to prime the cathode, and a solid protective layer or a buffer layer is formed on the cathode. However, electrophoretic coating is a very complicated film-forming physical-chemical, colloidal-chemical and electrochemical process, and factors affecting the quality of primer films are many, such as electrophoretic voltage stability and distribution, electrophoretic duration, electrophoretic medium, pH value, temperature, impurity content and the like. Meanwhile, electrophoretic coating can be divided into the following steps according to the working principle: electrophoresis of a moving interface; zone electrophoresis; isoelectric focusing electrophoresis; isokinetic electrophoresis; capillary electrophoresis, and the like. According to the electrophoretic medium, there are: paper electrophoresis; performing powder electrophoresis; gel electrophoresis; edge line electrophoresis, etc. The electrophoretic coating cathode has more benefits under ideal conditions, such as high coating efficiency, small coating loss and high utilization rate of 90-95%; the coating contains less organic matter components, so that the gas pollution and the environmental hazard are reduced; the coating has uniform thickness, strong adhesive force and good coating quality, and can be completely coated at one time aiming at various complex structures. However, most of the existing cathodic electrophoretic coating equipment has the following problems:

(1) the existing electrophoretic coating equipment mostly adopts simple constant-speed electrophoresis, on one hand, the coating surface can be basically paved by repeating electrophoretic coating for many times, the coating efficiency is low, and on the other hand, the coating bonding interface is fragile, so that primer can easily fall off.

(2) The stability of the conventional cathode electrophoresis coating equipment in the hanging and moving processes is still not high enough, the coating deposition position is changed due to slight shaking in the electrophoresis operation process, a coating with spot spots and uneven thickness is formed, and even more, primer cannot be formed after repeated coating for many times. Meanwhile, the cathode is severely shaken in the moving process, so that the undried coating is thrown off, and the adverse effects can also be formed.

(3) The existing coating equipment has the problems of low efficiency and poor effect in degreasing and washing operations, for example, before electrophoretic coating, only a spray washing mode is simply adopted to remove grease on the surface of a cathode, the high-viscosity characteristic of the grease can cause the cleaning mode to have poor effect, and the residual grease can form an obstruction area and even can not be painted. Meanwhile, the conventional washing operation is also the same, and the existing equipment adopts a plurality of complicated processes of repeated operation to avoid the above conditions as much as possible, so that the construction period is long and the cost is huge.

(4) Most of the cathodes after operation are dried by adopting one-way constant-temperature air in the existing coating equipment, but on one hand, the drying rate of the primers in different areas is inconsistent and the forming is not uniform due to one-way drying, and on the other hand, the drying efficiency is extremely low and the quality cannot be guaranteed according to time process parameters.

Therefore, based on the above-mentioned drawbacks, there is still a need for research and improvement of a new cathodic electrophoretic coating apparatus in the technical field of coating apparatuses, which is a research focus and focus of the field at present, and more a starting point and a driving force of the present invention.
