PURPOSE: A blasting device of a vacuum adsorbing type is provided to improve an adsorbing force adsorbing a vacuum pad by increasing the cross sectional area of the vacuum pad exposed to a vacuum chamber and to easily separate and assemble the vacuum pad by fixing the vacuum pad with a vacuum adsorbing force. CONSTITUTION: A blasting device (10) of a vacuum adsorbing type comprises a frame (110), a vacuum pad (120), a vacuum pressure applying unit (140), and a vacuum line (130). The vacuum pad surrounds a space between the surface of an object and a first vacuum chamber (V1) and includes a second vacuum chamber by connecting to the lower end of the frame. The vacuum line connects the first vacuum chamber and the second vacuum chamber and delivers the vacuum pressure applied to the first vacuum chamber. The upper end of the vacuum pad is fixed to the lower end of the frame by the reduced pressure of the second vacuum chamber. |
