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.
