Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a component suction and conveyance device used, for example, in a component assembly machine for electronic circuit boards and the like.

[Conventional technology]

FIG. 6 is a perspective view showing the main parts of a conventional electronic component suction and conveyance device as shown in Japanese Patent Publication No. 81-34955. In FIG. 1, (1) is a printed circuit board;
(2) is a flat package IO which is transferred and mounted on a predetermined position on this printed circuit board, (31 is a robot main body arm for positioning it, and (4) is a drive device attached to the tip of this main body arm.

A vacuum suction device (4) for suctioning electronic components using this drive device is installed so that it can rotate and move up and down.

[Problem that the invention seeks to solve]

The vacuum suction device in conventional component suction and conveyance devices is integrated into the robot main body arm, so the suction force and suction surface can be adjusted according to changes in the shape and size of the electronic components being handled. The shape cannot be changed, so a wide variety of products can be produced using just one device.

There was a problem in that multi-shaped electronic components could not be handled.

This invention solves the above problems by making the vacuum suction device itself removable and replaceable.

A vacuum suction connection pipe (7) is provided that automatically communicates with the parts suction port (21) at the tip, and the vacuum suction device (4) is automatically connected to the vacuum source when replaced. ing.

[Effect]

In the case of this invention, since the distance between the left and right gripping pieces (6b) changes depending on the top and bottom, it is possible to grip vacuum suction devices of various sizes. The component suction port becomes K when it is automatically connected to the vacuum source when the device is installed.

When using another vacuum suction device equipped with a suction cylinder of a different size and shape as described in 21a), the same operation as above is performed, and the exchange of the vacuum suction device at that time can be done without any problem by adjusting the opening degree between each of the gripping pieces. It is something that is done.

In the above embodiments, an apparatus for suctioning and conveying electronic components onto an electronic circuit board or the like has been described, but what is suctioned and conveyed is not limited to electronic components.

〔Effect of the invention〕

Since the component suction and conveyance device of the present invention is configured as described above, various vacuum suction devices with nine component suction openings of different shapes and sizes can be used in one device, and moreover, it is possible to use the component suction device in the attached state. This has the effect that the suction port can be automatically connected to the vacuum source.
