Patent ID: 7679072

Claim:
A surface treatment apparatus for molded polymer products, comprising: a product feeding unit ( 10 ) having a jig ( 11 ), the jig ( 11 ) changeably holding a molded polymer product and sequentially feeding the molded polymer product through a plurality of processing units of the surface treatment apparatus; a product loading and discharging unit ( 20 ), on which the molded polymer product to be surface-treated is placed to be held by the jig ( 11 ) of the product feeding unit ( 10 ), and a completely surface treated molded polymer product is released from the jig ( 11 ) to be placed onto the product loading and discharging unit; a first impurity removing unit ( 30 ) placed at a side of the product loading and discharging unit ( 20 ) for removing impurities from the molded polymer product while the molded polymer product held by the jig ( 11 ) on the product loading and discharging unit ( 20 ) is fed through the product feeding unit ( 10 ); an inlet vacuum unit ( 40 ) placed at a side of the first impurity removing unit ( 30 ) and having an interior maintained at a predetermined degree of vacuum, the inlet vacuum unit comprising an inlet having openable gates ( 90 ) at opposite end thereof so that the molded polymer product held by the jig ( 11 ) of the product feeding unit ( 10 ) passes through the interior of the inlet vacuum unit; a product surface ion treatment unit ( 50 ) placed at a side of the inlet vacuum unit ( 40 ) and having an interior maintained at a predetermined degree of vacuum, with an ion gun ( 51 ) provided in the ion treatment unit to scan ion beams onto a surface of the molded polymer product held and fed by the jig ( 11 ) of the product feeding unit 910 ) in the ion treatment unit; a gas supply unit ( 60 ) connected to the product surface ion treatment unit ( 50 ) and supplying gas to the product surface ion treatment unit ( 50 ); an outlet vacuum unit ( 70 ) placed at a side of the product surface ion treatment unit ( 50 ) and connected thereto, and having an interior maintained at a predetermined degree of vacuum, the outlet vacuum unit comprising an inlet and an outlet having respective openable gates ( 90 ) at opposite ends thereof so that the molded polymer held by the jig ( 11 ) of the product feeding unit ( 10 ) passes through the interior of the outlet vacuum unit; and a second impurity removing unit ( 80 ) placed between the outlet vacuum unit ( 70 ) and the product loading and discharging unit ( 20 ) and preventing impurities from sticking on the surface of the molded polymer product fed from the outlet vacuum unit ( 70 ), and removing impurities from the surface of the molded polymer product.
