Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, and in particular to an electrophoretic device for a coating production line. Background Technology

[0002] In the field of coating production, electrophoresis is an important surface treatment technology that is widely used in the coating of various metal products. It can give products a uniform, dense and corrosion-resistant coating, significantly improving product quality and service life.

[0003] However, traditional electrophoresis devices have many safety hazards in practical applications. Most devices are not completely sealed during operation, and personnel can easily touch live parts while the device is running, causing electric shock accidents and posing a serious threat to the life safety of operators.

[0004] Meanwhile, after the electrophoresis process, a large amount of excess electrophoretic solution often adheres to the surface of the workpiece. Traditional treatment methods are not only inefficient and difficult to remove excess electrophoretic solution quickly and thoroughly, but may also cause the electrophoretic solution to drip in subsequent processing stages, polluting the production environment, affecting product quality stability, and increasing subsequent cleaning costs and process difficulty. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrophoresis device for coating production lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrophoresis device for a coating production line includes a base, an electrophoresis tank at the upper end of the base, an electrophoresis anode plate installed at the bottom of the electrophoresis tank, an L-shaped plate fixedly connected to the upper end of the base, a conductive disk below the horizontal part of the L-shaped plate, a connecting column fixedly connected to the lower end of the conductive disk, and multiple hooks fixedly connected to the lower end of the connecting column; a rotating mechanism for rotating the multiple hooks; and a lifting mechanism for rotating the connecting column.

[0008] Preferably, the rotating mechanism includes a loop frame disposed below the horizontal part of the L-shaped plate, a drive motor is installed at the bottom inner part of the loop frame, the output shaft of the drive motor passes through the loop frame and is fixedly connected to a connecting plate, and the lower end of the connecting plate is fixedly connected to the upper end of the conductive plate.

[0009] Preferably, the connecting plate is made of insulating material.

[0010] Preferably, the lifting mechanism includes an electric telescopic rod installed at the lower end of the horizontal part of the L-shaped plate. The telescopic end of the electric telescopic rod is fixedly connected to the upper end of the U-shaped frame. Two guide rods are symmetrically fixedly connected to the upper end of the U-shaped frame. The upper ends of the two guide rods both penetrate the horizontal part of the L-shaped plate and are slidably connected.

[0011] Preferably, a support ring is fixedly connected to the inner wall of the electrophoresis tank, and a sliding groove is provided at the upper end of the support ring.

A through opening is provided at the inner bottom of the sliding groove, and the upper end of the power receiving block passes through the opening of the sliding groove.

[0012] Preferably, an annular blocking edge is fixedly connected to the upper end of the base.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0019] 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.

[0020] Reference Figure 1-3The electrophoresis device for the coating production line includes a base 1, an electrophoresis tank 11 at the upper end of the base 1, an electrophoresis anode plate 13 installed at the bottom of the electrophoresis tank 11, an L-shaped plate 2 fixedly connected to the upper end of the base 1, a conductive disk 8 below the horizontal part of the L-shaped plate 2, a connecting column fixedly connected to the lower end of the conductive disk 8, and multiple hooks 9 fixedly connected to the lower end of the connecting column. The workpiece can be suspended through the hooks. After the subsequent lifting mechanism is started, the conductive disk 8 fully contacts the contact block 16, and the workpiece on the hook 9 is completely located in the electrophoresis liquid. The height of the electrophoresis liquid after the workpiece is fully immersed in the electrophoresis liquid is not higher than the height of the lower end face of the support ring 12.

[0021] It also includes a rotating mechanism for rotating multiple hooks 9. The rotating mechanism includes a loop frame 4 located below the horizontal part of the L-shaped plate 2. A drive motor 5 is installed at the bottom of the inner part of the loop frame 4. The output shaft of the drive motor 5 passes through the loop frame 4 and is fixedly connected to a connecting plate 7. The lower end of the connecting plate 7 is fixedly connected to the upper end of the conductive plate 8. The connecting plate 7 is made of insulating material.

[0022] It also includes a lifting mechanism, which is used to rotate the connecting column. The lifting mechanism includes an electric telescopic rod 3 installed at the lower end of the horizontal part of the L-shaped plate 2. The electric telescopic rod 3 is a multi-stage telescopic rod with a large telescopic range. The telescopic end of the electric telescopic rod 3 is fixedly connected to the upper end of the U-shaped frame 4. Two guide rods 6 are symmetrically fixedly connected to the upper end of the U-shaped frame 4. The upper ends of the two guide rods 6 both penetrate the horizontal part of the L-shaped plate 2 and are slidably connected.

[0023] The inner wall of the electrophoresis tank 11 is fixedly connected to a support ring 12. The upper end of the support ring 12 is provided with a sliding groove 14. A sliding contact block 16 is provided in the sliding groove 14. The lower end of the contact block 16 is elastically connected to the inner bottom of the sliding groove 14 through a spring 15. The inner bottom of the sliding groove 14 is provided with a through opening. The upper end of the contact block 16 passes through the groove opening of the sliding groove 14. Furthermore, an external power supply with a protective resistor is provided. The contact block 16 is electrically connected to the negative terminal of the external power supply through a wire (the wire is long, and the movement of the contact block 16 will not affect the conductivity). The positive terminal of the external power supply is electrically connected to the electrophoresis anode plate 13. Multiple hooks 9 are made of conductive material.

[0024] The upper end of the base 1 is fixedly connected to an annular blocking edge 10. The inner part of the annular blocking edge 10 is the same as that of the electrophoresis tank 11, and is slightly larger than the diameter of the conductive disk 8 and the connecting disk 7. After the electrophoresis is completed, the subsequent lifting mechanism will move the connecting disk 7 up to the point where it is about to leave the annular blocking edge 10, and then the rotating mechanism will be started.

[0025] In this invention, the operator suspends the workpieces to be electrophoretically coated one by one onto multiple hooks 9. The hooks 9 are made of conductive material to ensure that the current can be smoothly conducted to the workpiece surface during the subsequent electrophoresis process. The electric telescopic rod 3 is activated, and its telescopic end extends downwards, causing the U-shaped frame 4 to move downwards synchronously. Since the U-shaped frame 4 is fixedly connected to the conductive disk 8 via a connecting plate 7, the conductive disk 8 also descends. The lower end of the conductive disk 8 is connected to the hooks 9 via connecting posts, thereby causing the hooks 9 with the suspended workpieces to descend. During the descent, two guide rods 6 slide on the horizontal part of the L-shaped plate 2, providing guidance and ensuring the workpieces are properly aligned. The conductive plate 8 and hook 9 descend smoothly. When the conductive plate 8 descends to contact the contact block 16, the contact block 16 continues to be pressed down, causing the contact block 16 to slide downward in the slide groove 14. The spring 15 is compressed. At this time, the contact block 16 is electrically connected to the negative terminal of the external power supply through the wire, and the positive terminal of the external power supply is electrically connected to the electrophoresis anode plate 13, forming a complete electrophoresis circuit. At the same time, as the conductive plate 8 descends, the workpiece on the hook 9 is gradually immersed in the electrophoresis liquid in the electrophoresis tank 11 until the workpiece is completely immersed. The height of the electrophoresis liquid is not higher than the height of the lower end face of the support ring 12, ensuring that the electrophoresis operation is carried out in a sealed and safe environment.

[0026] Under the action of an electric field, charged paint particles move toward the workpiece surface, which serves as the cathode, and deposit on the workpiece surface to form a uniform coating. During the electrophoresis process, a stable electric field is formed between the electrophoretic anode plate 13 and the hook 9 (which serves as the cathode), ensuring the quality and uniformity of the electrophoretic coating and improving the uniformity of the electrophoretic coating.

[0027] When the electrophoresis operation reaches the preset time, the electric telescopic rod 3 is activated to retract, which drives the U-shaped frame 4, conductive disk 8, connecting column and hook 9 to rise, thereby lifting the workpiece out of the electrophoresis solution; during the rising process, the conductive disk 8 leaves the contact block 16 and disconnects the electrophoresis circuit.

[0028] When the connecting plate 7 rises to the point where it is about to leave the annular blocking edge 10, the drive motor 5 is started, causing the hook 9 to drive the workpiece to rotate at high speed. Under the action of centrifugal force, the excess electrophoretic liquid on the surface of the workpiece is quickly thrown off, dripping into the annular blocking edge 10 and flowing back into the electrophoresis tank 11. This not only avoids the waste of electrophoretic liquid, but also facilitates other processing operations on the workpiece in the future.

[0029] After the excess electrophoretic liquid on the workpiece surface is completely removed, turn off the drive motor 5 to stop the workpiece rotation. Then, after starting the electric telescopic rod 3 to retract to the initial height, the operator can remove the workpiece that has completed the electrophoretic coating from the hook 9 and proceed with the subsequent processing steps.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
