Part attachment work support system and part attachment method

Abstract

This system is provided with: an imaging means for imaging a work space, together with a workpiece to which parts are to be attached, in the direction of the line of sight of an operator at the viewpoint position of the operator; a position and orientation information acquisition means for acquiring position and orientation information representing the relative position and orientation relationship of the viewpoint of the operator and the workpiece in the work space; a virtual image generation means for generating, on the basis of the position and orientation information, a three-dimensional virtual image representing the viewpoint position and attached parts in the direction of the line of sight; an image synthesis means for generating a synthesized image formed by superimposing the virtual image on an actual image of the work space; and a display means for displaying the synthesized image. This system enables mixed reality technology to be utilized to greatly improve the efficiency of part attachment work.

Description

technical field [0001] The present invention relates to a part mounting work support system for supporting part mounting work using composite reality technology, and more particularly, to a part mounting work support system suitable for supporting pre-welding work of parts and a part mounting method using the system . Background technique [0002] In the past, when welding parts such as suspension metal parts to the workpiece, such as Figure 7 As shown in (a), the position of the mounting part 41 on the workpiece 40 is previously marked 42, and the operator uses the marked line 42 as a mark to perform pre-welding of the part 41 ( Figure 7 (b)). [0003] However, when the size of the workpiece to which the component is attached is large, or the workpiece has a curved surface, the scribing operation itself may be difficult to perform, and the scribing operation may take a long time. [0004] In addition, if scribing is performed before forming the workpiece, there is also a...

Problems solved by technology

[0003] However, when the size of the workpiece to which the parts are attached is large, or the workpiece has a curved surface, etc., sometimes the scribing work itself is difficult to perform, and the scribing work may take a lot of time.

[0004] In addition, if the scribing is performed before the forming of the workpiece, there is also a problem that the scribing position is shifted due to the plastic deformation during the forming.

[0005] In addition, the mounting position of the part is drawn to describe the information of the mounted part, etc., but sometimes the operator mistakenly installs the direction during pre-soldering

As a result, rework may occur and work efficiency may decrease

[0006] Furthermore, in the inspection after the parts are mounted on the workpiece, it is also necessary to confirm the mounting state with reference to drawings, etc., so there is also a problem that it is difficult to visually judge whether the mounting state is good or not.
