Description

Electrodepositing device using a barrel {The electropainting device to use the barrel}

The present invention relates to an electrodeposition coating device, and more specifically, a barrel and an environmentally friendly anion type for storing a large number of small-size coatings (small screws, bolts, shafts, etc.). The present invention provides an electrodeposition coating device capable of efficiently electrodeposition coating various small size parts using electrodeposition paint.

In general, the coating work for surface treatment of metal material is known as electrodeposition coating, electrostatic powder coating, etc., and the electrodeposition coating apparatus related to the present invention is widely used as a rack or a hanger type or a basket type. It is used.

In the above-described rack type and basket type electrodeposition coating work, a large number of coating materials to be surface treated on a rack are settled in a treatment tank in which electrodeposition paint is stored, and the electrodeposition paint (+) in the treatment tank is applied to the coating material (-). Electrodeposition is to be carried out by the coating, this type of rack electrodeposition coating is a cumbersome to manually hang the coating to be surface-treated as mentioned above, and the coating is also limited to relatively large products It has been used and had the following disadvantages.

In other words, in the conventional electrodeposition coating work such as rack type, the rack is placed on the rack to settle the rack in the treatment tank so that the electrodeposition coating is performed, which processes small-size coating materials such as small screws, bolts, pins, and shafts. When you want to hang these small sized objects on the rack, it is not only cumbersome, but also wastes a lot of manpower and time. If the size is very small, it is almost impossible to work on the rack. will be.

On the other hand, as shown in Figure 6, small-size bolts, etc. for coupling wheels to inline skates, etc. have been previously used by surface treatment of zinc plating, etc., such plating treatment adversely affects pollution and environmental pollution, Environmentally friendly work is required to paint the surface.

In response to the times, the above-mentioned rack type electrodeposition coating work requires a lot of work time and manpower in the electrodeposition coating treatment of various kinds of coating materials as described above, and has considerable economic and technical problems when employing them. There is an urgent need for a new method of electrodeposition that can replace this.

Therefore, in the present design, even a small sized coating material can be efficiently processed in large quantities, and by using an anion type electrodeposition paint, which is an environmentally friendly electrodeposition paint, the environmentally friendly purpose of electrodeposition coating work is achieved. It is intended to provide a new electrodeposition coating device that can maximize the productivity by improving the work efficiency and efficiency by enabling a large amount of work easily.
