Abstract
A coating apparatus includes a dispenser that includes a discharge port and a displacement sensor, the discharge port being configured to be capable of discharging liquid from a vertical direction the displacement sensor being configured to detect a distance in the vertical direction between the discharge port and the coating region, a drive device that drives the dispenser, a dispenser movement control unit that controls the drive device to move the dispenser along a predetermined coating path, a tilt detection unit that detects a tilt of the coating surface with respect to a reference plane based on the distance detected by the displacement sensor, and a coating path correction unit that corrects the coating path based on the tilt of the coating surface detected by the tilt detection unit.
Claims10
A coating apparatus comprising:
- a dispenser that includes a discharge port and a displacement sensor, the discharge port being configured to be capable of discharging liquid from a vertical direction to a coating region provided on a coating surface of an object to be coated, and the displacement sensor being configured to detect a distance in the vertical direction between the discharge port and the coating region;
- a drive device that drives the dispenser;
- and
- a control device that controls the dispenser and the drive device,
- wherein the control device including:
- a dispenser movement control unit that controls the drive device to move the dispenser along a length of a predetermined coating path;
- a tilt detection unit that detects a tilt of the coating surface with respect to a reference plane extending in a direction intersecting the vertical direction, based on the distance detected by the displacement sensor;
- and
- a coating path correction unit that corrects the length of the predetermined coating path based on the tilt of the coating surface detected by the tilt detection unit, wherein
- when the coating path correction unit corrects the length of the predetermined coating path, the dispenser movement control unit moves the dispenser along the corrected length of the predetermined coating path.
