Problem: To provide a technology for forming a planar liquid film having less surface unevenness than ever before using a jet-type discharge device.

Solution: Provided is a planar liquid film forming method of forming a planar liquid film on an application target using a jet-type discharge device having a plurality of discharge ports, and an apparatus for implementing the method. In the method, the plurality of discharge ports are arranged on a straight nozzle arrangement line 140, and are arranged with such a distance from one another that globs of a liquid material having landed on the application target can join together to form a linear liquid film. The method includes: a unitary linear liquid film forming step of forming a unitary linear liquid film 404 by discharging the liquid material such that a plurality of liquid globs simultaneously discharged from the plurality of discharge ports have no contact with one another before landing on the application target, and by letting globs of the liquid material having landed join together on the application target; and a specific planar liquid film forming step of forming a specific planar liquid film 405 from a plurality of unitary linear liquid films 404 by successively executing the unitary linear liquid film forming steps while moving the jet-type discharge device and the application target relative to each other in a direction perpendicular to the nozzle arrangement line 140 so that the plurality of unitary linear liquid films 404 join together.

The present disclosure provides a painting robot and a painting method using the painting robot. The painting robot includes: an arm control unit which controls operation of the robot arm; a head control unit which controls driving of nozzles of the nozzle head; a distance measuring device which measures the distance between the painting portions and the nozzle discharging surface; and an image processing portion which forms a three-dimensional model for painting, which is a three-dimensional model, based on the painting coverage of the vehicle expected to be painted. The head control unit, based on the distances measured between the painting portions in the three-dimensional model for painting and an imaginary nozzle head or the distances measured by distance measuring device, controls to discharge paint from nozzles with distances within the prescribed range, and to not discharge paint from nozzles outside the prescribed range.

A coating device coats a to-be-coated object including a recessed portion extending in a first direction. The coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller moves the head in the first direction while causing the nozzle surface and the recessed portion to face each other in a posture in which a length of a first component along the first direction of the head is larger than a length of a second component of the head intersecting the first component.

A nozzle clamp includes a body defining a first surface and an opposing second surface. The nozzle includes an arm pivotally connected to the body and configured to move between first and second positions. The arm includes a bore therethrough and a protrusion that is configured to contact the nozzle. The nozzle includes a fastener movable within the bore of the arm and configured to contact the second surface of the body. The clamp is movable between a first configuration and a second configuration.
