Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a method of mounting articles when parts such as a case are attached and assembled.

[Conventional technology]

When a work B (for example, a case) is mounted on a conventional work A (for example, a coil or the like), the work B is attached by a suction head.
The work A is aligned with a centering claw or the like, while the work A is positioned by a separate mechanism under the suction head, and the work head A and the work B are lowered.
And were fitted and attached. In this case, the work B and the suction head are aligned, but the work A and the suction head are not considered so much.

If such a work B is a case, the work B is
Inward warpage may occur on the wall surface of itself. However, there is no mounting method that corrects it.

Further, the suction of the work by the suction head is performed by a method of sucking only one surface of the work (the upper surface when the work is a case).

Further, an example of aligning a press-fitted article and a press-fitted article is disclosed in Japanese Utility Model Publication No. 55-23785. In this conventional example, the press-fitted article is aligned and pushed into the inner peripheral surface of the press-fitted article that is loosely fitted and stored in the mold jig. That is, the press-fitted article sucked by the suction cylinder and the press-fitted article in the die jig are aligned by the same claw piece.

In the one disclosed in Japanese Utility Model Publication No. 55-23785, the closing operation of the claw piece is performed by abutting the claw piece against the die jig due to the lowering of the suction cylinder, and the position by the deformation of the one claw. There is a problem that it is difficult to maintain the alignment accuracy.

Further, in the work of pushing the press-fitted article into the aligned press-fitted article, the claw piece maintains a strongly closed state until the final pushing is completed, so that the press-fitted article tends to spread slightly by fitting. Therefore, there is a problem that a smooth fitting cannot be obtained.

[Problems to be Solved by the Invention]

As described in the above-mentioned conventional method, the work A cannot be accurately aligned with the suction head, or the alignment accuracy cannot be maintained for a long time, so that the work A and the work B cannot be fitted and mounted. There is a problem of difficulty.

In the case where the wall surface of the work B is inwardly warped, the work A and the work B cannot be fitted due to the warpage, or the fitting prevents the press-fitted article from slightly expanding. As a result, there is a problem that smooth fitting cannot be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to solve these problems and to provide a method in which the positioning accuracy of articles when attaching and assembling parts such as a case is maintained for a long period of time and the mounting is smooth.

[Means for Solving the Problems]

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

That is, using a suction head that has independently movable claws and is movable up and down, the work B is suctioned by the suction head with the claws opened, and then the work A is arranged in the direction in which it is arranged. Move the suction head and lower it with the claw,
After that, the claw is closed to bring the work A into contact with the tip of the claw, the work B and the work A are aligned, and the suction head is lowered while the claw is closed to move the work. By partially fitting the work B to the work A, then opening the claw, and further lowering the suction head, the work A is further pushed into the work B, and the work A and the work B The present invention provides a method of mounting an article, characterized in that the fitting with the product is completed, or alternatively, an independently openable / closable claw, a concentric inner cylinder and an outer cylinder are provided, and the inner cylinder is inclined. Using a vertically movable suction head having a suction surface, the work B is suctioned by the inner cylinder of the suction head with the claw open, and then the suction head is moved in the direction in which the work A is arranged. Then descend with the nail After that, the claws are closed and the work A is brought into contact with the tip of the claws, the work B and the work A are aligned, and the suction head is lowered with the claws closed. Then, the end corners of the work B are fitted to the work A, the outer cylinder is moved so that the work B becomes horizontal, and the work A and the work B are partially fitted. A method for mounting an article, characterized in that the work A is pushed into the work B and the fitting between the work A and the work B is completed by opening the claw and then further lowering the suction head. Alternatively, the work B is sucked by a suction head provided with a pair of suction ports communicating with a vacuum pump, and the work A aligned with the work B and the work B are fitted together. When The method of mounting an article according to claim 1.

[Action]

Since the work A is also aligned by the claw for aligning the work B, it is possible to prevent the positional deviation between the work A and the work B from occurring.

Further, at the time of fitting, the suction head is lowered to partially fit the work B with the work A, the claw is then opened, and then the suction head is further lowered to further push the work A into the work B. By completing the fitting of the work A and the work B with each other, or by lowering the suction head, the end corners of the work B are fitted with the work A, and the work B is placed outside so that the work B becomes horizontal. The work A is pushed into the work B by moving the cylinder to partially fit the work A and the work B, then opening the claw, and then further lowering the suction head to fit the work A and the work B. By so doing, it is possible to prevent the fitting from being forcedly pushed in, and yet it is possible to perform smooth and reliable mounting.

Further, by independently closing the openable claws and bringing the work A into contact with the tip of the claw, only the force for contacting the work A is applied to the tip of the claw. Since a large external force is not applied, it is possible to maintain a constant alignment accuracy without being deformed.

In the case where the work B is warped, the work B is sucked by first fitting the end corners of the work B with the work A or by a suction head having a pair of suction ports communicating with the vacuum pump. As a result, the work A and the work B can be smoothly fitted to each other with the inward warp of the work B being corrected.
