Abstract

An application robot applies a primer to a car body. The application robot includes an applicator for the primer, a camera, a controller, a cap for preventing dripping of the primer, a cap attaching/detaching unit for collecting the cap, and an arm. The camera is moved with the applicator to which the cap is attached, and detects the position of a specific part on the body, the camera being moved by activating the arm. The applicator applies the primer to a position to apply the primer on the body after the cap is detached, the position being specified by the controller. The cap attaching/detaching unit moves the cap holding part toward the body and collects the cap.

First claim

What is claimed is:

1. An application robot that applies fluid agents to a conveyed object conveyed by a conveyor, comprising:
an applicator to apply the fluid agents to the conveyed object;
a position sensor to detect a position of a specific part on the conveyed object;
a controller to specify a position to apply the fluid agents based on a detection result of the position sensor;
a dripping preventing member that is removably provided on the applicator and prevents dripping of the fluid agents when the fluid agents is not applied;
a collector to collect the dripping preventing member detached from the applicator; and
an arm that supports the applicator so as to move the applicator to the position to apply the fluid agents,
wherein the position sensor is provided on the arm along with the applicator, so as to be moved by operation of the arm to detect the position of the specific part on the conveyed object while the dripping preventing member is attached to the applicator, wherein upon the position to apply the agents being specified by the controller and the dripping preventing member being detached, the applicator applies the agents onto the conveyed object, and wherein the collector includes a collection part to collect the dripping preventing member and an extending part to move and extend toward the conveyed object while supporting the collecting part, the collecting part being moved toward the conveyed object by the extension of the extending part so as to collect the dripping preventing member.

2. The application robot according to claim 1 , further comprising a receiver to receive the fluid agents dripping from the applicator,
wherein the receiver is provided on the collector and is moved to the conveyed object by the extension and movement of the extending part.

3. The application robot according to claim 1 , wherein the position sensor includes:
an imaging unit to capture an image of the conveyed object, and
the position sensor detects the position of the specific part on the conveyed object and a state of application of the fluid agents by the applicator on the conveyed object based on the image of the conveyed object, the image being captured by the imaging unit.

4. The application robot according to claim 1 , wherein the conveyed object is a body,
the position sensor detects, from above the body, a position of a specific part on the body, and
the applicator applies the fluid agents from above the body.
