BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a complex cleaning device, and more particularly, to an ultrasonic cleaning device, a cleaning nozzle, and an electrolytic washing and cleaning section, which can perform complex cleaning processes individually or in combination, Precision precision molds, injection precision molds, press precision molds, automobile parts, electric / electronic parts, and precision parts composed of different kinds of materials.

Cleaning is a process to remove contaminants attached to the surface of products or parts. It is one of the important element technologies of all industries. Especially, it produces defective products It is a process carried out with the aim of minimizing the occurrence, improving the quality and function of the product, and facilitating the subsequent process. Background Art Ultrasonic cleaning devices have been widely used as a device widely used in the cleaning industry.

The ultrasonic cleaning device is an ultrasonic wave (20 kHz ~ 2 MHz) installed at the bottom of the tank to generate ultrasonic waves in the tank to remove contaminants attached to the objects to be washed. However, in the case of severe contamination, not only the cleaning is smoothly performed but also the deteriorated contaminants are reattached. In addition, as electronic products, precision parts and precision molds are miniaturized, densified, and highly integrated, processes are complex and the number of processes continues to increase. Due to such process increase and complexity, fine particles, metal impurities, surface adsorption chemicals Although the fine pollutants have a great influence on the reliability of the product, only the cleaning of the existing ultrasonic cleaning apparatus has a limit to complete cleaning.

In order to solve this problem, Japanese Patent Application No. 11-281193 has developed a system in which an ultrasonic wave is installed in a slot nozzle to allow ultrasonic waves to reach the substrate together with the nozzle. However, such a product is also advantageous for application to a flat substrate as a slotted nozzle, but it is disadvantageous for curved products.

In addition, in the patent document 10-2009-0058307, ultrasonic waves are applied to the nozzles as ultrasonic nozzles to develop nozzles suitable for semiconductor wafer cleaning. In addition, it is not easy to control the installation of ultrasonic waves in each nozzle, and it is difficult to uniformly clean the nozzle due to a change in pressure depending on the spray angle of the nozzle.

For this reason, a complex cleaning device including an ultrasonic wave and an electrolytic device (Japanese Patent Application No. 2007075181) has been developed. However, such a cleaning device has an advantage that it can be cleaned without surface damage using electrolysis, In addition, there is a problem that the water is metal, so that the cleaning effect can be exerted. Also, there is a problem that the portion where the electricity is difficult to enter is not easily cleaned at corners, and in recent years, the products made of different materials have been increasing. It is difficult to carry out precise cleaning through the conventional cleaning device.
