Description

Technical Field

[0001] This utility model belongs to the technical field of electrophoretic coating equipment for automotive parts, specifically, it relates to an electrophoretic tank for electrophoretic coating of automotive parts. Background Technology

[0002] In the production process of electrophoretic coating for automotive parts, the electrophoretic tank is the core processing equipment, and its performance plays a decisive role in the electrophoretic coating effect.

[0003] According to the public announcement (CN215668254U), an electrophoresis tank device for electrophoretic coating of automotive parts is disclosed. This technology discloses "including an electrophoresis tank body, a working tank arranged on the left side inside the electrophoresis tank body, a partition block arranged on the right side of the working tank, a motor fixedly connected to the bottom of the partition block, a first gear fixedly connected to the middle of the bottom end of the motor, a second gear meshing with the right side of the first gear, the second gear fixedly connected to the lower part of the outer circumference of a first rotating shaft, and a second stirring blade fixedly connected to the top of the first rotating shaft through the partition plate, etc., which has the technical effect of preventing the electrophoretic liquid inside the device from condensing, which is beneficial to industrial production, indirectly improving production efficiency, and is worthy of vigorous promotion."

[0004] However, in the aforementioned comparative documents, the stirring blades are all located at the bottom of the tank, and the orifice plate is fixed above the stirring blades, which obstructs the vortex formed by stirring. This results in the lack of effective guidance and stirring of the flow of the electrophoretic liquid in the upper part of the tank, leading to significant differences in the concentration and ion distribution of the electrophoretic liquid in different areas of the tank. Consequently, the thickness of the electrophoretic coating on the surface of automotive parts is inconsistent, which seriously affects the appearance quality and protective performance of the product and fails to meet the coating requirements of high-end automotive parts.

[0005] To address the aforementioned issues, this application proposes an electrophoresis tank for electrophoretic coating of automotive parts. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an electrophoresis tank for electrophoretic coating of automotive parts, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An electrophoresis tank for electrophoretic coating of automotive parts includes a tank body. A partition is fixedly connected to the inner wall of the tank body. A motor is fixedly connected through the bottom wall of the tank body. A drive gear is fixedly connected to the output end of the motor. A column is fixedly connected to the bottom of the tank body. A sleeve is rotatably connected to the outer wall of the column. A mesh plate is fixedly connected to the top of the column. A driven gear is fixedly connected to the outer wall of the sleeve, and the driven gear meshes with the drive gear. A turbine fan is fixedly connected to one end of the outer wall of the sleeve, and the turbine fan is located above the partition. A rotating rod is fixedly connected to the bottom outer wall of the turbine fan. An extension rod is slidably connected to the inner wall of the rotating rod. An abutment rod is fixedly connected to the end of the extension rod away from the rotating rod. A vertical rod is fixedly connected to the top of the abutment rod. A rubber pad is fixedly connected to the side of the vertical rod near the inner wall of the tank body. A roller is rotatably connected to the bottom of the abutment rod, and the outer wall of the roller abuts against the inner wall of the tank body.

[0009] Preferably, a sliding column is fixedly connected to the inner wall of the rotating rod, and a hole adapted to the sliding column is opened on the extension rod. A return spring is fixedly connected to the end of the extension rod near the turbine fan, and the end of the return spring away from the extension rod is fixedly connected to the inner wall of the rotating rod. The return spring is wound around the outer wall of the sliding column. By setting the sliding column and the return spring, it is convenient to restrict the movement path of the extension rod, and at the same time, it is convenient to assist the extension rod to retract into the interior of the rotating rod.

[0010] Preferably, the outer wall of the electrophoresis tank body is provided with heat dissipation holes, which are located in the cavity between the electrophoresis tank body and the partition plate. By providing heat dissipation holes, it is convenient to dissipate heat from the cavity between the electrophoresis tank body and the partition plate.

[0011] Preferably, the bottom of the electrophoresis tank body is fixedly connected with a support leg, and the inner side wall of the support leg is threaded with a stabilizing plate. By setting the support leg and the stabilizing plate, it is convenient to adjust the stability of the device according to the placement location of the device.

[0012] Preferably, a baffle is rotatably connected to the outer side wall of the electrophoresis tank body, and a handle is fixedly connected to one end of the outer side wall of the baffle. The handle is curved. By setting the baffle and the handle, it is convenient for the operator to inspect the inside of the device.

[0013] Preferably, a hook is fixedly connected to the outer side wall of the electrophoresis tank body, and a buckle is fixedly connected to the outer side wall of the baffle. The buckle is adapted to the hook. By setting the hook and buckle, it is convenient to restrict the baffle and prevent the baffle from being opened by force during the operation of the device.

[0014] In summary, the technical effects and advantages of this utility model are as follows: The electrophoresis tank for electrophoretic coating of automotive parts, by setting up columns, sleeves, driven gears, drive gears, turbine fans, rotating rods, extension rods, contact rods, uprights, rubber pads, and rollers, facilitates the synchronous agitation of the electrophoretic liquid above the screen, avoiding slow liquid flow above the screen and the formation of eddy dead zones. This prevents insufficient renewal of the electrophoretic liquid on the back of the workpiece during suspended coating, thus avoiding affecting the uniformity of the coating.

[0015] The use of the rotating rod, sliding column, return spring, and extension rod makes it easy to pull the extension rod, avoiding excessive friction between the extension rod and the inner wall of the electrophoresis tank body during reset, thus preventing the extension rod from getting stuck.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4An electrophoretic coating tank for automotive parts includes a main body 1. A partition 101 is fixedly connected to the inner wall of the main body 1. A motor 2 is fixedly connected through the inner bottom wall of the main body 1 and connected to an external power source. A drive gear 5 is fixedly connected to the output end of the motor 2 and is located in the cavity between the partition 101 and the main body 1. A column 3 is fixedly connected to the inner bottom of the main body 1. A sleeve 31 is rotatably connected to the outer wall of the column 3, penetrating the partition 101 and rotatably connected to it. A mesh plate 22 is fixedly connected to the top of the column 3. The mesh plate 22 has multiple holes and is located above the partition 101. A driven gear 4 is fixedly connected to the outer wall of the sleeve 31 and meshes with the drive gear 5. A turbine fan 6 is fixedly connected to one side of the outer wall of the electrophoresis tank 101. The turbine fan 6 is located above the partition plate 101. A rotating rod 7 is fixedly connected to the bottom outer wall of the turbine fan 6. An extension rod 10 is slidably connected to the inner wall of the rotating rod 7. An abutting rod 11 is fixedly connected to the end of the extension rod 10 away from the rotating rod 7. The abutting rod 11 is cylindrical. There is a certain gap between the outer wall of the mesh plate 22 and the inner wall of the electrophoresis tank body 1. The outer wall of the abutting rod 11 is in contact with the mesh plate 22 and the outer wall of the electrophoresis tank body 1 respectively. A vertical rod 12 is fixedly connected to the top of the abutting rod 11. A rubber pad 13 is fixedly connected to the side of the vertical rod 12 near the inner wall of the electrophoresis tank body 1. The rubber pad 13 is in contact with the inner wall of the electrophoresis tank body 1. A roller 14 is rotatably connected to the bottom of the abutting rod 11. The outer wall of the roller 14 abuts against the inner wall of the electrophoresis tank body 1.

[0025] In use, motor 2 is started, driving drive gear 5 to rotate. Drive gear 5 then drives driven gear 4 to rotate. Since driven gear 4 is fixedly connected to sleeve 31, and turbine fan 6 is fixedly connected to the outer wall of sleeve 31, driven gear 4 rotates synchronously with drive gear 5, thereby stirring the electrophoresis liquid inside the electrophoresis tank body 1. At this time, the rotation of sleeve 31 will drive rotating rod 7 to rotate synchronously. Also, because there is a gap between mesh plate 22 and electrophoresis tank body 1... With a fixed gap and the contact rod 11 located within the gap, when the rotating rod 7 rotates, the contact rod 11 will move along the outer wall of the screen plate 22. During the movement, the sliding column 8 slides inside the rotating rod 7 to adapt to different sizes of the electrophoresis tank body 1. During the movement of the contact rod 11, the upright rod 12 located at the top of the contact rod 11 synchronously stirs the electrophoretic liquid above the screen plate 22, thereby improving the fluidity of the electrophoretic liquid above the screen plate 22, avoiding the formation of eddy dead corners above the screen plate 22, and improving the coating uniformity of the workpiece.

[0026] Reference Figure 4The inner wall of the rotating rod 7 is fixedly connected to a sliding column 8. Taking one of the rotating rods 7 as an example, there are two sliding columns 8, which are symmetrically distributed inside the rotating rod 7. The extension rod 10 has holes that are adapted to the two sliding columns 8. The end of the extension rod 10 near the turbine fan 6 is fixedly connected to a return spring 9. There are two return springs 9. The ends of the two return springs 9 away from the extension rod 10 are fixedly connected to the inner wall of the rotating rod 7, and the two return springs 9 are respectively wrapped around the outer wall of the two sliding columns 8. As the rotating rod 7 rotates continuously, the extension rod 10 reciprocates linearly inside the rotating rod 7, thereby continuously pulling the two return springs 9. When the extension rod 10 moves towards the inside of the rotating rod 7, the two return springs 9 pull the extension rod 10 with their own elasticity to prevent the extension rod 10 from getting stuck during the retraction process.

[0027] Reference Figure 1 The outer wall of the electrophoresis tank body 1 is provided with heat dissipation holes 17. Multiple heat dissipation holes 17 are evenly distributed on both sides of the electrophoresis tank body 1, and all the heat dissipation holes 17 are located in the cavity between the electrophoresis tank body 1 and the partition plate 101. During the operation of the motor 2, heat will be continuously dissipated. At this time, the heat dissipation holes 17 dissipate heat into the cavity to prevent the temperature inside the cavity from becoming too high.

[0028] Reference Figure 1 and Figure 5 The bottom of the electrophoresis tank body 1 is fixedly connected with four support legs 15. The four support legs 15 are located at the four corners of the bottom of the electrophoresis tank body 1. The inner sidewalls of the four support legs 15 are threaded with stabilizing plates 16. When placing the electrophoresis tank body 1, the operator can adjust the distance between the stabilizing plates 16 and the support legs 15 according to the placement location, so as to facilitate the adjustment of the stability of the electrophoresis tank body 1 and prevent the device from shaking during use.

[0029] Reference Figure 1 and Figure 5 A baffle 18 is rotatably connected to the outer wall of the electrophoresis tank body 1. A handle 21 is fixedly connected to one end of the outer wall of the baffle 18. The handle 21 is curved. The operator can pull one end of the baffle 18 through the handle 21 to open the cavity and inspect the parts inside the cavity.

[0030] Reference Figure 5 A hook 19 is fixedly connected to the outer wall of the electrophoresis tank body 1, and a buckle 20 is fixedly connected to the outer wall of the baffle 18. The buckle 20 is adapted to the hook 19. When the baffle 18 is closed, the operator can use the hook 19 and the buckle 20 to engage the baffle 18 with the electrophoresis tank body 1, so as to prevent the roller 14 from hitting the baffle 18 when rotating, which would cause the baffle 18 to open.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
