Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis equipment, in particular to an electrophoresis line cathode conductive device. Background Art

[0002] Electrophoretic line generally refers to electrophoretic coating production line. Electrophoretic coating is a special coating film forming method. The object to be coated is the cathode. The electrophoretic coating used is cationic (positively charged). It is a coating method in which the conductive object to be coated is immersed in a water-diluted, low-concentration electrophoretic coating tank as the cathode, and a corresponding anode is set in the tank. Direct current is passed between the two electrodes to precipitate a uniform, water-insoluble coating film on the object to be coated.

[0003] There is a cathode conductive device in the electrophoresis line, which is usually composed of a connector and a conductive copper bar. The connector is used to provide current, and the conductive copper bar is set on the conveyor chain. The conveyor chain is used to convey the workpiece, so that the workpiece enters the electrophoresis coating tank in an assembly line manner. The current of the connector will reach the workpiece along the conductive copper bar and the conveyor chain. During the movement of the conveyor chain, the conductive copper bar on the conveyor chain will continuously rub against the connector, which is easy to cause the conductive copper bar and the connector to wear after long-term use. For this reason, a cathode conductive device for an electrophoresis line is proposed. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an electrophoresis line cathode conductive device includes a connector 1, which is fixedly connected to the side wall of a mounting plate 3. A conductive copper bus 2 is provided on the side of the connector 1 away from the mounting plate 3. The conductive copper bus 2 is connected to the connector 1 through an anti-wear component. An extrusion component acting on an anti-wear roller 5 is also provided on the mounting plate 3.

[0021] Among them, the anti-wear part consists of a U-shaped plate 4, an anti-wear roller 5 and a conductive rod 11. The U-shaped plate 4 is fixedly connected to the side wall of the mounting plate 3. A rotating shaft 14 is rotatably installed between the two vertical plates of the U-shaped plate 4. An anti-wear roller 5 is sleeved on the outer wall of the rotating shaft 14 and fixedly connected to the anti-wear roller 5. Both the rotating shaft 14 and the anti-wear roller 5 are conductive. A connecting groove 12 that crosses the rotating shaft 14 is opened at the center of the shaft end of the rotating shaft 14. The conductive rod 11 is fixedly connected to the output end of the electrical switch 1. The conductive rod 11 is inserted into the connecting groove 12 and is rotatably connected to the rotating shaft 14.

[0022] When in use, the current generated by the electrical connector 1 can be directed to the conductive copper bar 2 through the provided conductive rod 11, rotating shaft 14 and anti-wear roller 5. This installation method can replace the contact between the conductive copper bar 2 and the electrical connector 1 with the contact between the conductive copper bar 2 and the anti-wear roller 5. When the conductive copper bar 2 is transported along the conveyor chain, the sliding friction between the conductive copper bar 2 and the electrical connector 1 is converted into rolling friction between the conductive copper bar 2 and the anti-wear roller 5, thereby effectively alleviating the wear of the conductive copper bar 2.

[0023] Among them, the extrusion assembly includes a guide rod 6, a spring 7 and a connecting plate 8. Two guide rods 6 are fixedly connected to the side wall of the mounting plate 3 away from the electrical connector 1. The two guide rods 6 slide through the connecting plate 8. The outer surface of the guide rod 6 is sleeved with a spring 7, and the two ends of the spring 7 are fixedly connected to the mounting plate 3 and the connecting plate 8 respectively.

[0024] When in use, the spring 7 is in a compressed state, so that the anti-wear roller 5 is closely attached to the side wall of the conductive copper bus 2, thereby preventing the anti-wear roller 5 from separating from the conductive copper bus 2 when the workpiece is subjected to electrophoresis.

[0025] Wherein, both ends of the connecting plate 8 are fixedly connected to fixing plates 9 , and fixing holes are provided on the fixing plates 9 .

[0026] The connection plate 8 can be fixed by the cooperation of the fixing holes and the external fixing bolts.

[0027] A pressure dividing plate 13 is arranged between the guide rod 6 and the mounting plate 3 .

[0028] The pressure dividing plate 13 can decompose the extrusion force of the spring 7 on the mounting plate 3 .

[0029] Among them, an anti-slip plate 10 is sleeved on the upper end of the side wall of the guide rod 6, and the anti-slip plate 10 is fixedly connected to the guide rod 6.

[0030] The anti-slip plate 10 can prevent the guide rod 6 from being separated from the connecting plate 8.

[0031] The utility model provides a cathode conductive device for an electrophoresis line, and the specific working principle is as follows:

[0032] When in use, the current generated by the electrical connector 1 can be guided to the conductive copper bar 2 through the provided conductive rod 11, the rotating shaft 14 and the anti-wear roller 5. This installation method can replace the contact between the conductive copper bar 2 and the electrical connector 1 with the contact between the conductive copper bar 2 and the anti-wear roller 5. When the conductive copper bar 2 is transported along the conveyor chain, the sliding friction between the conductive copper bar 2 and the electrical connector 1 is converted into rolling friction between the conductive copper bar 2 and the anti-wear roller 5, thereby effectively alleviating the wear of the conductive copper bar 2. At the same time, by compressing the spring 7, the anti-wear roller 5 is tightly attached to the side wall of the conductive copper bar 2, thereby preventing the anti-wear roller 5 from separating from the conductive copper bar 2 when the workpiece is electrophoresed.
