Description

Technical Field

[0001] The invention relates to the technical field related to the anti-oxidation treatment of aluminum plates, and in particular to an electrophoretic painting device for the anti-oxidation treatment of aluminum plates with a bearing component. Background Art

[0002] In the production process of aluminum plates, they need to be treated for oxidation resistance, which can be performed using an electrophoretic coating device. Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in an electrophoretic liquid migrate in a directional manner and deposit on the surface of a substrate of one of the electrodes. However, the existing electrophoretic coating device for anti-oxidation treatment of aluminum plates still has certain defects when used; During use, the aluminum plate needs to be hung on the hook for painting, but the hanging method is not suitable for all aluminum plates, which reduces the practicality of the overall painting device. Therefore, the overall limit increases the operation time and reduces the overall processing efficiency; In order to overcome the above defects, the prior art 1 (Chinese patent with application number 202210792079.0 and application date 2022-07-05) is an aluminum plate electrophoretic painting device for communication equipment, comprising a bearing mechanism and a containing mechanism, wherein the containing mechanism is arranged on the upper part of the bearing mechanism, and further comprising a painting mechanism for containing the aluminum plate for electrophoretic painting, wherein the ring support leg and the bearing bottom frame are arranged so that the whole device body can remain stable during operation; the zigzag filter is arranged so that metal debris brought by long-term use can be filtered during electrophoretic painting to avoid participating in the next electrophoretic painting; and under the action of the circulating pump, the overflowed electrophoretic paint can be sent to the spotting pool, so as to continue to participate in the next step of electrophoretic painting; There is also prior art 2 (Chinese patent with application number 202323167157.7 and application date 2023-11-23). ​​An aluminum plate electrophoretic painting device includes: a shell, a controller, an electrophoretic liquid discharge port, a drive motor, and a U-shaped auxiliary bracket; an aluminum plate electrophoretic painting device, which adjusts the speed of the drive motor according to the controller, so that the aluminum plate fixed on the U-shaped auxiliary bracket is evenly and slowly immersed in the electrophoretic paint. After the aluminum plate is immersed in the electrophoretic liquid, after the voltage is applied, the pigment and resin particles in the liquid will be attracted to the surface of the workpiece due to the electric field force to form a covering layer. After the aluminum plate on a certain U-shaped auxiliary bracket is painted, the aluminum plate is removed, and a new aluminum plate is installed to circulate the paint, so that multiple aluminum plates can be processed at one time, saving the processing time of the aluminum plate and improving the production efficiency of the aluminum plate. When the drive motor drives the U-shaped auxiliary bracket to rotate, the electrophoretic liquid inside the shell can also be stirred to prevent uneven precipitation and mixing of the electrophoretic liquid; And prior art three (Chinese patent with application number 202211340389.5 and application date 2022-10-28) an aluminum plate electrophoretic painting device, the bearing mechanism includes a base plate, a fixedly connected water tank is arranged near the middle of the bottom plate surface, the water tank has a first groove, two symmetrically distributed partitions are arranged in the groove, a fan is arranged in the partition, and a low-speed motor is arranged in the fan, and a symmetrically distributed first sliding seat is arranged near both sides of the base plate, a second groove is arranged in the first sliding seat, and a fixedly connected first motor is arranged at one end of the second groove, and the rotating shaft is rotated by the fourth motor to drive the rotating plate to rotate, so that the first clamping plate and the second clamping plate are synchronously contracted and relaxed, thereby clamping and fixing aluminum plates of different models, and the first clamping plate and the second clamping plate are provided with a first anti-slip pad and a second anti-slip pad to play an anti-slip role to prevent the aluminum plate from loosening and falling off.

[0003] Although the existing technology can be applied to aluminum plates of different models, during the working process, the aluminum plate is clamped with a clamping plate for painting, which increases the complexity of the operation. When the clamping force is too large, the aluminum plate is prone to deformation, which may cause the coating to become uneven during the electrophoresis process. In addition, the symmetrically arranged clamping plates are suitable for symmetrically arranged aluminum plates for painting, which reduces the overall applicability. When the aluminum plate is supported by a supporting bottom frame for painting, the position where the bottom frame contacts the aluminum plate is prone to uneven coating thickness, and bubbles are prone to accumulate at the contact position, resulting in reduced surface smoothness of the aluminum plate, which affects the coating quality.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original electrophoretic painting device for anti-oxidation treatment of aluminum plates with a load-bearing component. Therefore, we proposed an electrophoretic painting device for anti-oxidation treatment of aluminum plates with a load-bearing component that can well solve the above problems.

When the clamping force is too large, the aluminum plates are prone to deformation, which may cause the coating to become uneven during the electrophoretic process. In addition, the symmetrically arranged clamping plates are suitable for painting symmetrically arranged aluminum plates, which reduces the overall applicability.
