Abstract

PURPOSE:To perform the application of paint while reducing the motion of a robot regardless of any change in an application angle, by providing a pluraity of openings for ejecting an applying agent at an applicator nozzle to be attached to the wrist part of the robot in a manner such that they are arranged to direct to different directions. CONSTITUTION:A straight-advancing hole 12a and a bending hole 12b cutting it at a right angle are provided at the top end of a nozzle 11 to be attached to the wrist part of a robot. Each of the spouting holes 12a, 12b is connected to a gas tank for ejecting an applying agent, and a line for ejecting gas is made so as to freely switch the supply of the applying agent to the hole 12a or 12b. Consequently, the motion of the robot can be made sufficiently small without strain, and the work of sealig can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a method of applying a coating agent to different surfaces of.

A nozzle attached to the robot's wrist allows the first
In order to apply adhesive, resin, etc. to the object l as shown in the figure, if the application positions 2a and 2b of the object 1 are perpendicular to each other as shown in the figure, the conventional robot 3 shown in FIG.
Also, the nozzle 4 has only one outlet.

Each part of the robot 3 must be moved significantly.

In other words, when performing cooling work on object 1 as shown in Fig. 1, the sealing line 2a to 2b
Since the discharge direction of the nozzle 4 must be changed by 90 degrees in order to change the direction, the robot 3 is required to perform complicated movements as shown in FIG.

The operation time becomes longer and the operation control becomes more complicated. In addition, since the robot moves a lot, when working in a narrow space, there will be interference between the robot and the object, resulting in areas left uncoated, making it difficult to fully automate these tasks using robots. -).

The present invention has been developed in view of the conventional situation mentioned above. This is a method that allows coating with less movement of the robot even if the coating angle changes.In the method of applying the coating agent to each electrical conductivity surface (intersected by the robot), it is possible to apply the coating agent to each conductive surface (intersected by the robot). At least two coating agent discharging ports are provided in the coating nostle so that the discharging directions thereof are different,
It is characterized by selecting a coating agent suitable for the coating surface and discharging the coating agent.

Embodiments according to the present invention will be described below based on the drawings.

FIG. 3 shows the tip of the nozzle 11 attached to the robot's wrist. The nozzle 11 is provided with a straight hole 12a and a bent hole 12b perpendicular to the straight hole 12a. A gun for discharging the agent is connected and can be switched freely.

To apply the sealant to the object l using the above device,
First, the sealant is discharged from the straight hole 12a of the nozzle 11 for the touring line 2a, and then the sealant is discharged from the refraction hole 12b for the Norlinger line 2b. By doing this, the movement of robot 3 is the fourth one.
As shown in the figure, a small, reasonable movement is sufficient, and the sealing work can be easily accomplished.

According to the present invention, since the discharge position of the porous nostle is selected according to the coating surface and the coating is applied, there is no need for the robot to make forced movements even if the angle of the coating surface changes greatly. It is possible to automate the coating operation even when the work is done in an extremely narrow space.
