Production device for a graphene thin film

A production device for graphene thin film, comprising:

• a deposition plate in contact with a substrate at an obtuse or acute angle, wherein the substrate is coated with a graphene oxide solution;
• a reciprocating linear motion device connected to the deposition plate to put the deposition plate into reciprocating linear motion;
• a holder for supporting the deposition plate;
• an angle adjusting device for rotatably supporting the holder, for adjusting an angle between the substrate and the deposition plate, and for maintaining the adjusted angle;
• a support fixture for supporting the substrate;
• a height adjusting device for adjusting a height of the support fixture to adjust an angle between the substrate and the deposition plate;
• a heating device installed in the support fixture to heat the substrate;
• a temperature adjusting device for adjusting a heating temperature of the heating device;
• an injecting device for injecting the graphene oxide solution;
• and
• an injection tube connected to the injecting device,
• wherein the holder comprises a body;
• a groove formed in a side of the body to receive an end portion of the deposition plate;
• connecting members respectively extending from both end portions of the body;
• and an axis receiving hole respectively formed in the connecting members,
• wherein the reciprocating linear motion device comprises an axis receiving hole, an end portion of the reciprocating linear motion device is inserted between the connecting members of the holder, so that the axis receiving hole of the holder is aligned with the axis receiving hole of the reciprocating linear motion device,
• wherein the angle adjusting device comprises a rotating axis respectively inserted into the axis receiving hole of the holder and the axis receiving hole of the reciprocating linear motion device;
• and a fixing member engaging with the rotating axis to fix the holder and the reciprocating linear motion device,
• wherein the rotating axis and the fixing member are screw-coupled,
• wherein the deposition plate comprises a fixing member for fixing the injection tube.
