Abstract

Provided is a vacuum generator unit. The vacuum generator unit includes: the application valve of pressure fluid, which is controlled by the guiding electronic valve; the main body, which comprise one side connecting to the application valve of pressure fluid; the supplying port of pressure fluid, which is arranged at the other side of the main body and is provided with pressure fluid; the vacuum port, which is used to generate and eliminate vacuum; and discharging port, the pressure liquid which has passed through the supplying port or vacuum port is discharged through this port, wherein, the vacuum generated component which is generated at the vacuum port by the pressure liquid provided from the supplying port of pressure liquid, the first and the second storage components of pressure liquid which is used to storage pressure liquid to eliminate the vacuum generated at the vacuum port are generated at the main body.

Description

technical field [0001] The invention relates to a vacuum generating unit for creating and relieving vacuum. Background technique [0002] In general, a vacuum generating unit is used to move an object by a vacuum grip, for example, when soldering a semiconductor chip, mounting a semiconductor chip, carrying an ultra-small component, conveying paper to a printer, and suppressing the vacuum grip to Release the object at the desired location. [0003] Conventionally, a vacuum generating unit as disclosed in Korean Patent Registration No. 10-0387364 includes a vacuum forming valve and a vacuum eliminating valve. However, the conventional vacuum generating unit should include both the vacuum forming valve and the vacuum eliminating valve, and causes inconvenience of separately controlling the respective valves, and furthermore, the conventional vacuum generating unit cannot be made smaller in size and lighter in weight. Contents of the invention [0004] The present invention...
