The present invention relates to an automatic washing machine, and more particularly, to a metal mask (cleaning material) automatic washing machine using pneumatics.

Conventionally, as a washing machine for cleaning the metal mask, it is common to clean the surface of the metal mask by using vibration or wavelength of ultrasonic waves.

However, these ultrasonic cleaners are electric cleaners that use electricity primarily, such as problems such as fire / leakage during operation and drying operations depending on the type of cleaning liquid, and secondly, costs associated with replacement / repair of ultrasonic vibrators. Thirdly, when the cleaning solution is insufficient when cleaning the metal mask of the micro-opening part, problems such as ultrasonic welding due to the remaining soda cream in the opening occurred.

The present invention has been made in view of the problems and limitations of the conventional washing machine, and by using various air nozzles to remove the cleaning method depending on ultrasonic waves, using a rotating nozzle bar in which a plurality of supply nozzles are formed with a cleaning liquid and a high pressure air. By performing the three-dimensional cleaning on the surface and openings of the metal mask, it is to provide an automatic washing machine using the pneumatic holding up to safety because it operates from fully automatic cleaning to drying with only excellent cleaning power and pneumatic pressure.

In order to achieve the above object of the present invention, the automatic washing machine using the pneumatic device according to the present invention includes a circulation tank for storing the washing liquid, a level sensor for detecting the level of the washing liquid inside the circulation tank, and a filter from the circulation tank. An air pump for supplying the cleaning liquid into the apparatus, a first filter and a second filter for filtering the cleaning liquid pumped by the air pump, and a supply pipe of the cleaning liquid filtered by the first filter and the second filter A metal mask (cleaned object) is formed between a pair of rotary heads, a pair of nozzle bars connected to each rotary head, and a plurality of nozzles for rotating and supplying a cleaning liquid and a high pressure air. A metal mask fixing frame for supporting / fixing, a third filter for filtering the cleaning liquid used after the metal mask is cleaned, and the metal mask is dried to dry the metal mask after the cleaning. It consists only of a pair of air heaters for supplying / generating air, a pair of nozzles formed at the ends of the hot air air supply pipes connected to the air heaters to supply hot air air, and pneumatic components for automatically performing such an operation. It includes a control device.

The automatic washing machine using the pneumatic pressure eliminates the problem of the conventional ultrasonic washing machine, and at the same time, the washing liquid and the washing liquid obtained by directly spraying the washing liquid into the opening of the metal mask due to the washing liquid sprayed by spraying the high pressure washing liquid onto the metal mask. The cleaning power by the shock wave generated by impacting the metal mask and the cleaning effect of discharging foreign matter out of the opening of the metal mask by spraying high pressure air through the nozzle of the rotating nozzle bar are complicated and sequentially operated. The effect is maximized.
