Abstract:
An atmospheric pressure plasma apparatus, an infrared filter in-line assembly of a camera module including the same, a cleaning method using the same, and an infrared filter in-line assembling method of a cellular phone camera module using the same are provided to prevent reattachment of foreign materials by performing a nitrogen blowing process. An internal case(210) is formed to protect an internal device. A first electrode(220) is installed in the inside of the internal case. A gas line(230) is installed in the inside of the first electrode in order to exhaust a mixed gas through a plurality of holes. A dielectric(240) is formed on one surface of the first electrode. A conductive layer(250) is formed between the first electrode and the dielectric. A second electrode(260) is formed at a constant interval from the dielectric. A plurality of injection nozzles are formed in a constant interval on the second electrode. A mesh(270) is formed on a surface of the second electrode. The first electrode is separated at a constant interval from the dielectric in an inner surface of the internal case. The mixed gas and the plasma are discharged through the injection nozzles.
Abstract:
A plasma cleaning device is provided to form the plasma having a desired shape and to process various objects by varying an electrode structure of an electrode bar according to the object. A plasma cleaning device(200) comprises a chamber(210), a plurality of electrode bars(220), a pair of electrode plates(230), insulating members(240), and nuts(250). A plurality of first holes for electrode bars is formed in both side of the chamber. The electrode bar is passed through the hole, and a central part of the electrode bar is positioned inside the chamber and both ends of the electrode bar are exposed to the outside of the chamber. The electrode plates have a plurality of second holes for the electrode bars, having a bigger diameter than an outer diameter of the electrode bar. The insulating members are intervened among the first holes, electrode bars, and electrode plates. The insulating members seal the inside of the chamber and insulate the first holes, electrode bars, and electrode plates. The nut connects the electrode bar and the electrode plate electrically, and fixes the electrode plate.
