Abstract

A cleaning device ( 10 ) for a linear coating machine table comprising a vacuum suction device ( 1 ) having a plurality of first suction ports ( 11 ) facing a surface of an object to be cleaned; and at least one sticky roller ( 12 ) pivoted to the vacuum suction device ( 1 ) and being rotatable, the sticky roller ( 12 ) configured to adhere impurities on the surface of the object to be cleaned is provided. By sucking small particles on the linear coating machine table by the vacuum suction device ( 11 ) and by adhering relative large particles by the sticky roller ( 12 ), the cleanness of the linear coating machine table is improved, and hence the coating effect of a substrate is improved. A linear coating machine is also provided.

First claim
