Description

Technical Field

[0001] The utility model relates to the technical field of automobile body painting, in particular to an automobile body electrophoretic painting device. Background Art

[0002] At present, automobile body painting generally adopts electrophoretic coating process. The existing patent (Announcement No.: CN112210811B) discloses an automobile body electrophoretic coating device. The invention sets a stirring roller in the electrophoretic tank and cooperates with a spoiler mechanism to perform spoiler above the stirring roller, which can not only effectively improve the uniformity of the tank liquid and the paint, but also prevent the mixed liquid from overflowing. However, in actual application, the stirring roller in the above technical solution can only transport the paint horizontally in the electrophoretic tank, and cannot fully mix the paint and the tank liquid. In addition, the stirring roller and the spoiler mechanism occupy a large space in the electrophoretic tank, which may cause the automobile body to be unable to be completely placed in the electrophoretic tank, affecting the actual effect of the body painting. To this end, we propose an automobile body electrophoretic coating device. Utility Model Content

[0011] In the above scheme, the wiping assembly includes support rods fixed at both ends of the electrophoresis tank, a plurality of wiping rollers are movably sleeved on the support rods, and the ends of the support rods are connected to limit covers.

[0012] In the above solution, the wiping roller comprises a roller, the surface of the roller is covered with a water-absorbing layer, and a limiting axis is fixed at one end of the roller.

[0013] The advantages and beneficial effects of the utility model are as follows: by arranging a stirring mechanism in the electrophoretic tank, firstly, using motor one to drive spiral stirring shaft one to transport the paint that has sunk to the bottom of the electrophoretic tank to one end, and cooperating with motor two to drive spiral stirring shaft two to make the paint that has sunk to the bottom gradually move upward. Compared with the prior art, it can not only effectively alleviate the problem of paint sinking to the bottom, but also make the paint re-mixed with the tank liquid, effectively improving the uniformity of the paint.

[0020] See also Figure 1-3 , the utility model provides a technical solution: an electrophoretic coating device for automobile body, comprising an electrophoretic tank 1 provided with a stirring mechanism;

[0021] Specifically, when the automobile body is subjected to electrophoretic coating, a slide rail is provided above the electrophoretic tank 1, and a conveyor frame is slidably connected to the slide rail. The top of the conveyor frame is connected to the traction equipment, and the automobile body is connected to the bottom of the conveyor frame. An angle adjustment mechanism is provided at the upper end of the conveyor frame. The traction equipment is used to make the conveyor frame drive the automobile body to move along the slide rail to the top of the electrophoretic tank, and cooperate with the angle adjustment mechanism to make the automobile body completely placed in the electrophoretic tank for electrophoretic coating.

[0022] The stirring mechanism includes a horizontally arranged spiral stirring shaft 2, and the spiral stirring shaft 2 is located at the bottom of the electrophoresis tank 1, and spiral stirring shafts 5 are vertically arranged at both ends of the spiral stirring shaft 2. A motor 3 and a motor 12 are installed outside the electrophoresis tank 1. The spiral stirring shaft 2 is connected to the motor 3 by transmission, and the spiral stirring shaft 5 is connected to the motor 12 by transmission. The motor 3 and the motor 12 are respectively installed on the outer wall of the electrophoresis tank 1 through brackets.

[0023] Furthermore, the spiral stirring shaft 2 is provided as a pair and is respectively located at the front and rear sides of the electrophoresis tank 1; the contact area between the spiral stirring shaft 2 and the bottom coating in the electrophoresis tank 1 is increased, so as to fully stir the coating;

[0024] Further, a pulley 4 is installed on the end of the spiral stirring shaft 2 and the output shaft of the motor 3, and the pulley 4 is connected by a belt 1; one end of the spiral stirring shaft 2 passes through the electrophoresis tank 1 and is movably connected to the inner wall of the electrophoresis tank 1, and the motor 3 is located between adjacent spiral stirring shafts 2, and the end point of the output shaft of the motor 3 and the end point of the spiral stirring shaft 2 form a triangle parallel to the end face of the electrophoresis tank 1, and the belt 1 is connected in sequence along the end points of the triangle between the pulleys 4, and the motor 3 is started to make the spiral stirring shaft 2 rotate under the drive of the pulley 4;

[0025] Furthermore, the height of the top of the spiral stirring shaft 2 5 does not exceed the height of the middle of the electrophoresis tank 1; this prevents excessive fluctuations in the liquid level due to the top of the spiral stirring shaft 2 5 being too high, thereby effectively avoiding splashing;

[0026] Further, a pulley 26 is installed on the bottom end of the spiral stirring shaft 25 and the output shaft of the motor 212, and the pulley 26 is connected by a belt 2; the bottom end of the spiral stirring shaft 25 passes through the electrophoresis tank 1 and is movably connected to the inner wall of the electrophoresis tank 1, the pulley 26 is a double-groove pulley, the pulley 26 on the output shaft of the motor 212 is successively connected to the pulleys 26 at both ends of the electrophoresis tank 1 through the belt 2, and the belts 2 at both ends are connected in a triangle sequence, and the motor 212 is started to make the spiral stirring shaft 25 rotate under the drive of the pulley 26;

[0027] Specifically, by setting a stirring mechanism in the electrophoretic tank 1, firstly, the motor 13 is used to drive the spiral stirring shaft 12 to transport the paint that has settled to the bottom of the electrophoretic tank 1 to one end, and the motor 2 12 is used to drive the spiral stirring shaft 25 to make the settled paint gradually move upward. Compared with the prior art, it can not only effectively alleviate the problem of paint settling to the bottom, but also make the paint re-mixed with the tank liquid, effectively improving the uniformity of the paint. At the same time, the movement of the spiral stirring shaft 25 causes lateral fluctuations to form in the electrophoretic tank 1, and the movement of the spiral stirring shaft 2 causes longitudinal fluctuations to form in the electrophoretic tank 1. The two cooperate with each other. When the two fluctuations reach the liquid surface of the electrophoretic tank 1, the liquid surface fluctuations will be weakened, reducing splashing.

[0028] An overflow mechanism is provided on the upper part of the electrophoresis tank 1, and the overflow mechanism includes an overflow tank 7 which is not higher than the liquid level when the automobile body is not placed;

[0030] Specifically, by setting up an overflow mechanism, when the liquid level gradually rises when the vehicle body enters the electrophoretic tank 1, the mixed liquid with an excessively high liquid level will directly flow into the overflow tank 7 to avoid waste caused by the outflow of the mixed liquid. After the processing is completed, the mixed liquid in the overflow tank 7 will automatically flow back to the electrophoretic tank, which is convenient to use.

The end of the support rod 91 is connected to a limit cover 93, and the limit cover 93 is tension-connected to the end of the support rod 91 to prevent the wiping rollers 92 from easily detaching from the support rod 91. When the automobile body moves upward from the electrophoresis tank 1, the automobile body contacts the wiping rollers 92, and the wiping rollers 92 are used to wipe off the excess tank liquid and paint on the automobile body, thereby reducing the subsequent drying time.

[0033] Furthermore, the wiping roller 92 includes a roller 921, the surface of which is covered with a water-absorbing layer 922, which is fixed to the roller 921 by double-sided tape and other materials, and a limiting axis 923 is fixed at one end of the roller 921, so that the wiping roller 92 is equidistantly arranged on the support rod 91.
