Description

Technical Field

[0001] The utility model belongs to the technical field of electrophoretic coating, and particularly relates to a conductive structure of an electrophoretic hanger. Background Art

[0002] In order to enhance the anti-rust, anti-impact, and corrosion resistance of automobile bodies, the body-in-white vehicle painting line usually adopts the cathode electrophoresis process. The electrophoresis hanger conducts high-voltage direct current to the body-in-white through a conductive mechanism, so that a uniform, water-insoluble coating layer is deposited on the surface of the body-in-white. The existing technology generally transmits electricity through a C-shaped hanger arm. This conductive method will have the following problems:

[0003] 1. In order to make the conductive sealing plate and the copper brush mounting plate contact and conduct electricity, the conductive sealing plate adopts the method of welding the conductive sealing plate and the pad together. However, the conductive sealing plate and the pad are easily connected by welding, which makes the conductivity poor;

[0004] 2. The hanging beam is a closed cavity, and dust cannot escape, which easily causes contact discharge between the hanging beam and the C-shaped boom, causing the C-shaped boom to be burned through when conducting electricity.

[0005] Therefore, a conductive structure of an electrophoresis hanger is needed. Utility Model Content

[0006] The purpose of the utility model is to provide a conductive structure of an electrophoresis hanger, thereby solving the problem that the conductive structure of the existing electrophoresis hanger has poor conductivity and is easily burned through. The specific technical solution is as follows:

[0007] A conductive structure of an electrophoresis hanger, comprising a hanger beam, a C-shaped hanger arm, a conductive copper brush, a copper brush mounting plate and a conductive sealing plate, wherein the hanger beam is mounted with the C-shaped hanger arm, a copper brush mounting plate is mounted on one end of the hanger beam away from the C-shaped hanger arm, the conductive copper brush is mounted on the copper brush mounting plate, and the conductive copper brush is located outside the hanger beam, the conductive sealing plate is mounted on one end of the C-shaped hanger arm close to the conductive copper brush, the conductive sealing plate is a boss structure, and the boss end face of the conductive sealing plate is abutted against the copper brush mounting plate, so that the conductive sealing plate and the copper brush mounting plate can fit tightly without a pad.

[0008] Preferably, a through hole is provided on the side wall of the suspension beam close to one end of the conductive copper brush.

[0009] Preferably, the through hole has a size of 12*25 mm.

[0010] Compared with the existing technology, the utility model has the following beneficial effects:

[0011] 1. The utility model adopts a boss structure to directly contact the conductive sealing plate with the copper brush mounting plate, thereby avoiding the problem of poor conductivity between the conductive sealing plate and the pad plate caused by a gap between the conductive sealing plate and the pad, thereby improving energy utilization and reducing production costs.

[0012] 2. The utility model opens a 12*25mm through hole in the side wall of the suspension beam near the insulating bushing. The through hole can be used as an observation hole during maintenance, so that the operator can observe the inside of the suspension beam conveniently. At the same time, the through hole can also be used to introduce compressed air to blow away the particles and dust inside, so as to prevent the internal conduction from burning through the C-type suspension arm.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figures 1 to 3, install the copper brush mounting plate 4 on the end of the suspension beam 1 away from the C-shaped suspension arm 2 by bolts, connect the conductive copper brush 3 to the copper brush mounting plate 4 by bolts, and install the conductive sealing plate 6 on the end of the C-shaped suspension arm 2 close to the copper brush mounting plate 4 by welding. The conductive sealing plate 6 is made into a boss structure, and the end of the conductive sealing plate 6 with a smaller diameter faces the copper brush mounting plate 4 and fits tightly with the copper brush mounting plate 4. At this time, the conductive sealing plate 6 can cooperate with the limiting structure in the inner wall of the suspension beam 1, and can fit with the copper brush mounting plate 4 under the premise of avoiding interference with the bolts. Therefore, the current transmitted from the conductive copper brush 3 will be transmitted to the conductive sealing plate 6 through the copper brush mounting plate 4, and then from the conductive sealing plate 6 to the C-shaped suspension arm 2, and finally to the white body. Compared with the existing welding pad between the conductive sealing plate 6 and the copper brush mounting plate 4 for conduction, the resistance during current transmission is reduced, energy loss is saved, and the white body can better complete the electrophoresis process.

[0021] The hanging beam 1 and the C-shaped boom 2 are sheathed by insulating material, and there is a certain gap between the C-shaped boom 2 and the hanging beam 1. The present invention is used to open a through hole 5 on the side wall of the hanging beam 1, and the size of the through hole 5 is 12*25mm, which is convenient for operators to observe the hanging beam 1 and the C-shaped boom 2 during maintenance. At the same time, compressed gas can be introduced into the hanging beam 1 to remove the dust in the hanging beam 1 from the through hole 5 to avoid dust accumulation in the gap between the hanging beam 1 and the C-shaped boom 2, resulting in contact discharge between the hanging beam 1 and the C-shaped boom 2, causing the C-shaped boom to be burned through during conduction, thereby ensuring the stable operation of the conductive structure of the electrophoresis hanger and extending the service life of the conductive structure of the electrophoresis hanger.

[0022] In summary, the present invention reduces the energy loss of the electrophoresis process and the production cost by changing the structure of the conductive sealing plate 6 and the suspension beam 1, while extending the service life of the conductive structure of the electrophoresis suspension device.
