Coating apparatus including modular coating areas

A coating apparatus comprising:

• a first module constituting a coating area where a coating target is coated, the first module including a first frame;
• a second module constituting the coating area where the coating target is coated, the second module including a second frame;
• and
• two third modules configured to be coupled to each other, wherein:
• one of the third modules (i) is configured to be coupled to the first module, (ii) is coupled to be placed above, below, left or right of the first module when viewed in a cross section orthogonal to a movement path direction in which the coating target relatively moves along the coating area, and (iii) constitutes at least one of an air supply module configured to supply air to the coating area or an air exhaust module configured to exhaust air from the coating area:
• the other one of the third modules (i) is configured to be coupled to the second module, (ii) is configured to be placed above, below, left or right of the second module when viewed in the cross section orthogonal to the movement path direction, and (iii) constitutes at least one of the air supply module or the air exhaust module;
• when the first module and the second module are arranged to adjoin each other in the movement path direction, the first frame of the first module and the second frame of the second module that are arranged to adjoin each other are configured to be coupled together;
• the one of the third modules includes a duct connector or a duct component, the duct connector being configured to connect to an air supply duct, the duct component constituting a part of an air exhaust duct;
• the other one of the third modules does not includes the duct connector and the duct component;
• and
• at least one of the first module and the second module includes a coating robot.
