Advanced dip-coating equipment and dip-coating method using the same

A dip-coating apparatus comprising:

• a solution tank in which a coating solution is stored;
• a substrate-providing unit configured to dip a substrate in the coating solution and to withdraw the substrate out of the coating solution;
• an air-discharging unit configured to supply air to the substrate at a constant flow rate when the dipped substrate is lifted up;
• and
• a rate-controlling unit configured to control the substrate dipping rate and withdrawing rate,
• wherein the substrate-providing unit comprises a tubular body configured to fix the substrate and to locate the substrate in the solution tank,
• the air-discharging unit comprises a discharging tube through which air is discharged to the outside,
• the discharging tube is linked with an air compressor through a tube, and
• the rate-controlling unit is installed to be linked with the substrate-providing unit and is an automated device configured to insert the substrate to the solution tank at a constant rate, to allow the substrate to be dipped in the coating solution for a predetermined time and to withdraw the substrate out of the solution tank at a constant rate to be located at its original position.
