Description

Component transfer device and coating machine including the same

The present invention relates to a component transfer device for transferring a component (hereinafter referred to as a semi-finished product) to a desired position, and a coating machine for coating a coating material required for the component transferred by the apparatus.

The transfer device for transferring the parts supplied from the first position to the desired second position is used in various industries because it is a facility that forms the basis of the mass production method. For example, a transfer device is also applied to a coating machine that coats a surface with a coating material to impart a function or improve the quality of the surface.

In general, the conveying device transfers parts as the conveying body responsible for conveying the parts performs certain movements such as circular motion, reciprocating motion, and rotational motion. It is important to design so that it is secured. Therefore, in recent years, a conveying device has been developed and used in which a part is conveyed by attaching a part to a conveying body by magnetic force. In this type, it is important to reliably drop a part conveyed to a desired position from the conveying body. Inba, it is urgently required to prepare a solution for this.

A coating machine including a conveying device coats a coating material on a part continuously conveyed by the conveying device, that is, a coating object. The coating material is determined according to the type of coating target or the purpose of coating. For example, coatings such as screws (including screws, bolts, etc.), nuts, and rivets are coated with a powder or a liquid coating material for preventing leakage, leakage, contamination, and loosening.

Coating of the powdery coating material is performed by a nozzle, which sprays the coating material in one direction toward the coating object. However, such a simple spray method has a limitation in improving the working speed in coating the entire surface of the coating object. In addition, in the case of a coating object having a curved surface or irregular surface, uniformity with respect to the coating thickness could not be guaranteed at all. For example, when the screw is to be coated, the thickness of the coating material coated on the portion of the screw portion (curved surface) facing the nozzle in front is significantly thicker than that of the peripheral portion.
