[0041] The working principle and beneficial effects of the above technical solution are as follows: the electrophoresis tank 1 is filled with electrophoresis liquid, and a plurality of groups of columns 2 are fixed on the outer wall, which are used to support the electrophoresis tank to ensure its stability. The guide rail 3 is installed on the top of the electrophoresis tank 1, providing a sliding track so that the frame fixing component 4 can slide on the guide rail 3. The frame fixing component 4 is installed at the entrance of the electrophoresis tank 1 and is slidably connected through the guide rail 3, so that the frame can move smoothly in the electrophoresis tank 1 to ensure the positioning of the frame during the electrophoresis process. The mixing component 32 is installed inside the electrophoresis tank 1 to mix the electrophoresis liquid to ensure the uniformity and stability of the electrophoresis liquid, thereby improving the electrophoresis effect. The cathode plate 6 is fixed on the inner wall of the electrophoresis tank 1 as an electrode plate for cathode electrophoresis, which is used to provide an electric field during the electrophoresis process so that the paint particles on the frame are deposited on the surface of the frame to form a uniform coating.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 2-6 The mixing assembly 32 includes: a driving motor 7, which is fixedly arranged on the outer wall of the electrophoresis tank 1, a supporting shaft sleeve 1 9 and a supporting shaft sleeve 2 16 are both fixedly connected to the inner wall of the electrophoresis tank 1, an output shaft of the driving motor 7 moves through the supporting shaft sleeve 1 9 and extends into the electrophoresis tank 1, one end of the driving shaft 14 moves through the supporting shaft sleeve 2 16 and extends into the electrophoresis tank 1, and the other end of the driving shaft 14 is located on the outer wall of the electrophoresis tank 1.

[0046] Preferably, the waterproof ring sleeve 10 is fixedly sleeved on the end of the output shaft of the driving motor 7 located in the electrophoresis tank 1, and the two groups of fan-shaped stirring blades 11 are connected to the side of the waterproof ring sleeve 10 away from the supporting shaft sleeve 9 through bolts, and the two groups of driving rods 12 are fixedly provided with the annular outer wall of the waterproof ring sleeve 10.

[0047] Preferably, one end of the driving connecting rod 19 is movably sleeved on the end of the driving shaft 14 located in the electrophoresis tank 1, and the other end of the driving connecting rod 19 is movably provided with a limiting driving rod 20, and the end of the limiting driving rod 20 away from the driving connecting rod 19 is movably provided in the limiting driving member 17.

[0048] Preferably, the bottom of the U-shaped guide sleeve 18 is fixedly connected to the bottom of the inner wall of the electrophoresis tank 1, the guide push rod 21 is movably arranged in the U-shaped groove of the U-shaped guide sleeve 18, the limit drive 17 is fixedly connected to the guide push rod 21, and the limit ring 22 is fixedly connected to the top of the guide push rod 21.

[0049] Preferably, one end of the fixed rod 31 is fixedly connected to the inner wall of the electrophoresis tank 1, and the other end of the fixed rod 31 is fixedly provided with two groups of support shaft sleeves three 27, and a driving ring sleeve 25 is movably provided between the two groups of support shaft sleeves three 27, and the upper and lower ends of the driving ring sleeve 25 extend to form the same annular member 23, an arc-shaped guide groove 26 is provided on the outer wall of the driving ring sleeve 25, and one end of the driving rod 12 away from the waterproof ring sleeve 10 is arranged in the arc-shaped guide groove 26, and an avoidance groove 24 is provided on the annular member 23, and the diameter of the avoidance groove 24 is larger than the arc-shaped stirring blade of the fan-shaped stirring blade 11.

[0050] Preferably, a convex strip 29 is fixedly provided on the outer wall of the first connecting rod 28, and a groove matching the convex strip 29 is opened on the inner wall of the driving ring sleeve 25. The bottom of the first connecting rod 28 can move through two sets of supporting shaft sleeves 27 and the driving ring sleeve 25 and is rotatably connected to the limiting ring 22. A stirring member 30 is fixedly provided on the top of the first connecting rod 28.

[0051] The working principle of the above technical solution is: for the electrophoretic fluid used in the automobile painting process, since the electrophoretic fluid contains solid components such as pigments, resins and fillers, if it is not stirred for a long time, these solid components will gradually settle to the bottom of the tank, resulting in uneven composition of the electrophoretic fluid, affecting the uniformity and appearance quality of the coating, and uneven composition will lead to inconsistent coating thickness, affecting the anti-corrosion performance and aesthetics.

[0052] A plurality of mixing components 32 are symmetrically arranged on the front and rear inner walls of the electrophoresis tank 1. When the driving motor 7 is started to drive the pulley 8 to rotate, the waterproof ring sleeve 10 also rotates synchronously. The waterproof ring sleeve 10 not only provides a sealing function, but also fixes two groups of fan-shaped stirring blades 11. The two groups of fan-shaped stirring blades 11 rotate synchronously to stir the electrophoresis tank 1 to ensure uniform mixing of the electrophoresis liquid.

[0053] At the same time, the pulley 18 drives the pulley 2 15 to rotate through the belt 13, and the pulley 2 15 drives the driving shaft 14 to rotate accordingly. At this time, the driving shaft 14 drives the limit driving rod 20 to slide in the arc groove of the limit driving member 17 through the driving connecting rod 19. When the limit driving rod 20 moves from left to right in the limit driving member 17, the guide push rod 21 is driven by the limit driving member 17 to move upward along the U-shaped guide sleeve 18. At the same time, the driving rod 12 just moves into the arc guide groove 26 of the driving ring sleeve 25, and when the driving rod 12 rotates, the driving The movable rod 12 moves along the arc-shaped guide groove 26, thereby pushing the driving ring sleeve 25 to rotate. Since the convex strip 29 on the outer wall of the first connecting rod 28 is consistent with the groove on the inner wall of the driving ring sleeve 25, the driving ring sleeve 25 will drive the first connecting rod 28 to rotate while rotating, and the limit ring 22 is movably connected to the bottom of the first connecting rod 28. Without affecting the rotation of the first connecting rod 28, it can also enable the guide push rod 21 to move upward and push the first connecting rod 28 to move upward along the driving ring sleeve 25, so that the stirring member 30 on the top of the first connecting rod 28 moves upward while rotating.

[0054] When the first connecting rod 28 moves upward to the highest point, the avoidance groove 24 on the top of the annular member 23 just moves to overlap with the driving rod 12, thereby leaving an avoidance space for the driving rod 12 to continue rotating, and the arc-shaped blades of the fan-shaped stirring blade 11 will also Figure 5 to Figure 6 In the rotation process shown in FIG, the arc-shaped fan blade just passes through the avoidance groove 24, thereby ensuring that the fan-shaped stirring blade 11 and the driving rod 12 move within a specified range to avoid collision and interference.

[0055] While the driving shaft 14 continues to rotate and causes the limit driving rod 20 to move from right to left in the limit driving member 17, the guide push rod 21 pulls the first connecting rod 28 down, and the arc-shaped fan blade just passes through the avoidance groove 24, and the driving rod 12 enters the arc-shaped guide groove 26, thereby driving the driving ring sleeve 25 to rotate while the first connecting rod 28 also rotates synchronously.

[0056] In the above manner, the fan-shaped stirring blade 11 can continuously stir the electrophoresis liquid in the horizontal direction, and the stirring member 30 can intermittently move up and down in the vertical direction to stir the electrophoresis liquid, thereby further optimizing the mixing effect of the electrophoresis liquid.

[0057] The beneficial effects of the above technical solution are as follows: in the electrophoretic coating process, stirring the electrophoretic liquid is an important step to ensure coating quality and process stability. Compared with the traditional stirring only at the bottom of the electrophoretic tank, the horizontal and vertical stirring method of the mixing component 32 has the following significant advantages:

[0058] 1. Better composition uniformity: Ordinary bottom stirring may not be able to effectively stir the electrophoretic liquid in the entire tank, especially the liquid at the top and middle of the tank, while the combined horizontal and vertical stirring in the mixing component 32 can mix the electrophoretic liquid more comprehensively, ensure the uniformity of the liquid at each layer in the tank, and prevent the sedimentation of pigments and fillers.

[0059] 2. Prevent the formation of dead corners: Stirring only at the bottom can easily form dead corners in the electrophoresis tank, resulting in insufficient flow of electrophoresis fluid in certain areas. Horizontal and vertical stirring can more effectively cover the entire electrophoresis tank, eliminate dead corners, and ensure that every part of the electrophoresis fluid is fully mixed.

[0060] 3. Improve coating quality: Uniform electrophoretic liquid composition helps to form uniform coating thickness and quality. Through horizontal and vertical stirring, coating defects can be reduced and coating adhesion, glossiness and anti-corrosion performance can be improved.

[0061] 4. Stable process parameters: Horizontal and vertical stirring can more effectively maintain the stability of parameters such as pH value and conductivity of the electrophoretic liquid, avoid process fluctuations caused by local component changes, and ensure the stability of the electrophoretic coating process.

[0062] 5. Reduce microbial contamination: Continuous and effective stirring can prevent the deposition of organic matter in the electrophoresis fluid, reduce the growth and reproduction of microorganisms, and keep the electrophoresis fluid clean and active.

[0063] 6. Extend the service life of equipment: Horizontal and vertical stirring can reduce the deposition of solid components at the bottom of the tank, reduce the risk of equipment wear and blockage, extend the service life of the electrophoresis tank and related equipment, and reduce maintenance costs and downtime.

[0064] 7. Improve production efficiency: By improving the stirring method, the number of rework and inspections caused by uneven coating and defects can be reduced, and production efficiency and output can be improved.

[0065] And by designing the vertical and horizontal stirring to be intermittent, the vertical stirring combined with the lifting can cover different heights of the electrophoretic tank, ensuring that the electrophoretic liquid in the entire tank can be stirred. This three-dimensional stirring method can more effectively prevent the sedimentation of pigments and fillers and ensure uniform distribution of components, while the horizontal stirring can break the laminar flow of the liquid on the horizontal plane, enhance the stirring effect, and further ensure uniform components. Intermittent stirring can effectively reduce energy consumption and equipment wear, while maintaining the uniformity of the electrophoretic liquid at different time intervals. Vertical and horizontal intermittent stirring combined with lifting movement can ensure that there is no stirring dead corner in the entire electrophoretic tank and prevent the formation of sediments, especially at the bottom and wall of the tank. The reduction of sediments can improve the cleanliness and maintenance convenience of the equipment. Intermittent stirring can prevent the separation of components in certain areas due to long-term static. Through regular stirring actions, the dynamic balance of the electrophoretic liquid is maintained to ensure the stability of process parameters. Through multi-dimensional stirring methods, the uniformity of the electrophoretic liquid can be better maintained, the coating quality of each batch can be ensured to be consistent, and coating defects caused by uneven components can be reduced. This stirring design can more flexibly adapt to different process requirements. For example, by adjusting the stirring frequency and lifting speed according to different electrophoretic liquid compositions and coating requirements, the process parameters can be optimized and production efficiency and coating effects can be improved.
