Technical Field

[0001] The utility model relates to the technical field of electrophoresis production, and particularly discloses a fully automatic electrophoresis production line. Background Art

[0002] Electrophoresis refers to the phenomenon that charged particles move towards the electrode with the opposite electric property under the action of an electric field. In the industrial field, electrophoretic coating is a commonly used surface treatment method, and the coating is evenly deposited on the surface of the workpiece through electrophoresis to form a coating.

[0003] In the prior art, the electrophoresis production line generally has the problem of low production efficiency, which seriously restricts the production capacity and market competitiveness of enterprises. At the same time, resources such as degreasing liquid, silane liquid and electrophoresis liquid in the production line cannot be effectively recycled, which not only increases the production cost, but also causes serious environmental pollution. In addition, there is a lack of good cooperation and coordination between each process, which affects the production efficiency and product quality, and makes the stability and adaptability of the production line poor. Therefore, how to improve the production efficiency of the electrophoresis production line, reduce costs, reduce environmental pollution, and enhance the stability and adaptability of the production line has become an urgent technical problem in the current industry.

[0006] The degreasing device can effectively remove the grease and dirt on the surface of the workpiece, laying a good foundation for subsequent processing steps and ensuring the adhesion and quality of the coating. The provision of the first ultrasonic generator further accelerates the degreasing process, improves the degreasing effect and efficiency, and makes the surface of the workpiece cleaner. The silane coating formed by the silane device can enhance the adhesion of the workpiece to the electrophoretic paint, ensuring that the electrophoretic paint can firmly adhere to the workpiece after being processed by the subsequent electrophoretic device on the workpiece, and extending the service life of the workpiece after painting. The second ultrasonic generator speeds up the silane coating process, ensures the uniformity and integrity of the coating, and improves the protection performance of the product. The electrophoretic device can form a uniform and stable-quality electrophoretic coating on the surface of the workpiece.

Driven by the immersion pump, the immersion liquid circulates continuously, enabling the effective components in the immersion liquid to contact the workpiece more evenly, improving the effect and uniformity of the immersion treatment. The third filter membrane can effectively filter out impurities in the immersion liquid. This not only helps to maintain the cleanliness of the immersion liquid, reduces the adverse effects of impurities on the workpiece surface, but also can extend the service life of the immersion liquid, reduce the frequency and cost of replacing the immersion liquid. The filtered clean liquid flows back into the immersion tank for continued use, while the impurities are discharged from the immersion tank, ensuring that the quality of the liquid in the immersion tank is always in a good state, thus stably providing high-quality immersion treatment conditions for the workpiece and improving the quality and consistency of the product.
