Fully automatic processing system including automatic tray and automatic processing method using same}

The present invention relates to a processing system including a tray for fixing the position of a processing object and a processing method using the same. More specifically, it relates to a fully automatic processing system including a fully automatic tray and a fully automatic processing method using the same.

In a process of performing chemical milling by dipping a product in a conventional etching solution, it is desirable to obtain an etched surface as uniformly as possible without excessive removal of material. These requirements are particularly evident in the aerospace industry, where the goal is to improve airflow patterns and characteristics and improve long-term fatigue performance.

In the case of a conventional chemical milling process, a mounting fixture capable of fixing the product is formed on a tray, and after fixing the product to the mounting fixture, the tray is immersed in a tank containing an etching solution at a constant speed for a certain time to perform an etching process. carried out.

At this time, it was necessary to invert the fixture up and down to ensure that the etching was done uniformly on the product surface. When the product size is very large, the conventional chemical milling process requires a separate device such as a wire to secure the product and fixture. A fixture was added. Accordingly, in order to reverse the top and bottom phase of the product, the worker had to cut the wire and directly reverse the top and bottom of the product. At this time, because the size of the product was very large, it was difficult for a person to perform it directly.

In addition, the vertical reversal operation to ensure that etching is done uniformly on the product surface must be performed quickly (about 3 seconds) because etching occurs quickly. The operator directly cuts the wire, reverses the vertical phase, and then Additionally, connecting the product to the fixing fixture using a wire took a long time and it was difficult to obtain a uniform surface.

In addition, when fixing a large product with a wire, etc., a strong force must be used to position the product, which can cause defects to appear on the surface of the product due to the wire, which can affect the completeness of the product.
