Abstract:
1. A method of forming a spacer of double glazing by using a multi-joint robot to which an applicator head for applying a spacer forming material is rotatably attached and by applying the spacer forming material from the applicator head while the applicator head is being moved by the multi-joint robot along a periphery of an upper surface of one glass plate, the application head having a discharge port for the spacer forming material, which is directed to one direction, the periphery of the glass plate having linear regions with corner regions therebetween, the method comprising the steps of: discharging the spacer forming material from the discharge port of the applicator head in each linear region; stopping the discharge of the spacer forming material from the discharge port of the applicator head in each corner region; rotating the application head in each corner region to change the direction of the discharge port of the applicator head to a direction suitable for application in the next linear region adjacent the corner region; re-starting the discharge of the spacer forming material from the discharge port of the applicator head in the next linear region, such that a continuous spacer is formed in the corner region and the linear regions adjacent thereto, wherein the step of rotating the applicator head in each corner region further includes: wherein the step of discharging the spacer forming material in each linear region is performed such that a movement speed of the applicator head is faster in the linear regions than in the corner regions, and the step of rotating the applicator head in each corner region is performed such that the movement speed of the applicator head is equal to or lower than a speed corresponding to a rotation speed of the applicator head.
