Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching an article when attaching and assembling parts such as a case.

[Conventional technology]

Conventionally, when attaching workpiece B (for example, a case) to workpiece A (for example, a part such as a coil), workpiece B is attached using a suction head.
At the same time, workpiece A is positioned at the bottom of the suction head using a separate mechanism, and the suction head is lowered to fit and mount workpiece A and workpiece B. Ta. In this case, although the workpiece B and the suction head have been aligned, little consideration has been given to the alignment between the workpiece A and the suction head.

If work B is like this case, work B
Warpage may occur on the wall itself. However, there is no mounting method that corrects this.

Further, the suction head suctions the workpiece by suctioning only one side of the workpiece (or the upper side if the workpiece is a case).

[Problem to be solved by the invention]

In the conventional method described above, since the workpiece A cannot be accurately aligned with the suction head, there is a problem that the alignment of the workpiece A and the workpiece B is not accurate and it is difficult to mount the workpiece A and the workpiece B.

Furthermore, in cases where the wall surface of the workpiece B is warped inward, it has occurred that the workpieces A and B cannot be fitted together due to the warp.

The present invention aims to solve these problems and improve the reliability and accuracy of mounting articles when attaching and assembling parts such as cases.

[Means to solve the problem]

The present invention has the following means to achieve the above object.

That is, using a suction head that has a claw that can be opened and closed and is movable up and down with the claw, the workpiece B is picked up by the suction head with the claw open, and then the workpiece B is sucked in the direction in which the workpiece A is placed. The suction head is moved and further lowered, the claws are closed to align the workpiece B and the workpiece A, the suction head is further lowered to fit the workpiece B with the workpiece A, and then The article mounting method is characterized in that the claw is opened and the workpiece A is further pushed into the workpiece B to complete the fitting of the workpiece A and the workpiece B. Using a suction head that has a claw that can move up and down with the claw and has an inclined suction surface, the workpiece B is attracted by the suction head with the claw open, and then the workpiece B is moved in the direction in which the workpiece A is placed. The suction head is moved and further lowered, the claws are closed to align the work B and the work A, and the suction head is lowered to fit the end of the work B to the work A. Then, the workpiece B is moved horizontally so that the workpiece A and the workpiece B are partially fitted together, and then the claw is opened and the workpiece A is moved to the workpiece B.
The method of mounting an article is characterized in that the fitting of the workpiece A and the workpiece B is completed by pushing the workpiece A and the workpiece B into each other. The method for mounting an article according to claim 1 is characterized in that the workpiece B is fitted with the workpiece A that has been adsorbed and aligned with the workpiece B. [Function] Since the claws that align the workpiece B also align the workpiece A, it is possible to prevent positional deviation between the workpiece A and the workpiece B from occurring.

In addition, by lowering the suction head to fit workpiece B into workpiece A, and then opening the claw and pushing workpiece A further into workpiece B, the fitting between workpiece A and workpiece B is completed. Alternatively, lower the suction head to fit the end of work B to work A, then move work B horizontally to partially fit work A and B, and then open the claws to fit the workpiece A. By pushing work A into work B to complete the fitting of work 8 and work B, it is possible to securely attach the work without forcing the work.

In the case of a case where workpiece B is warped, first fit the end of workpiece B with workpiece A, or suction workpiece B with a suction head equipped with a pair of suction ports communicating with a vacuum pump. Accordingly, the workpiece and the workpiece B can be fitted with the workpiece B corrected for its inward warpage.
