Description

[Detailed description of the invention]

[0001]

The present invention relates to a work in which a guide member for a plate-like work and a receiving member for receiving the back surface of the work guided by the guide member are arranged at positions corresponding to the peripheral shape of the work. The present invention relates to a positioning device.

[0002]

2. Description of the Related Art This type of apparatus performs processing such as application of a sealer while setting a work such as a luggage door outer taken out of a pallet, or assembles a luggage door inner or the like of another work from above. Used in some cases. However, when the rigidity of the work is low, the work may be twisted in or before the pallet, and may float from the receiving surface of the receiving member in a state where the work is set on the positioning device. was there.

[0003]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a work positioning device of the kind described at the beginning which sets a plate-like work in a state where deformation such as torsion is forcibly corrected. The purpose is to provide.

[0004]

According to the present invention, a guide member for guiding the periphery of a work set from above at a position corresponding to the peripheral shape of a plate-like work and a guide member adjacent to the guide member are provided. In the work positioning device in which the receiving members receiving the back surface of the work are arranged, in order to achieve the above-mentioned object, the suction cup attached to the rod tip is positioned at a standby position above the work receiving surface of the receiving member,
In addition, air cylinders for raising and lowering the rod are arranged in at least four directions so as to be lowered from the standby position, and after sucking the back surface of the work guided along the guide member to each air cylinder, the suction cups Cylinder control means for detecting that the rod has descended to a position where the leading edge is flush with the work receiving surface and stopping the rod is attached.

[0005]

[Function] With the suction cup waiting at a position above the work receiving surface of the receiving member, a plate-like work is set from above to the front edge of the suction cup along the guide member, and the suction cup sucks the back surface of the work to which it belongs. I do. Each cylinder control means lowers the rod after sucking the work, and stops the rod by detecting that the rod has moved down to a position where the leading edge of the associated suction cup is flush with the work receiving surface. As a result, all sides of the work are forcibly set in close contact with the original work receiving surface of the receiving member regardless of the presence or absence of deformation.

[0006]

FIG. 1 shows a positioning device for a luggage door outer according to an embodiment of the present invention. According to the peripheral shape of the luggage door outer 1, the receiving member 10 with the suction cup according to the present invention is provided at the four corners, and the normal FIG.
The receiving members 20 provided with the guide members 21 shown in FIG.

As shown in FIG. 2, a receiving member 10 with a suction cup is provided with a guide member 2 inclined outward and for guiding the periphery of a luggage door outer 1 set from above, and a guide adjacent to the guide member. A pair of spaced-apart receiving members 3 and 3a for receiving the back surface of the luggage door outer 1 and the suction cup 11 are attached to the distal end of the rod 13, and the position of the work receiving surface 3c of the receiving members 3 and 3a and the like are adjusted. An air cylinder 16 that controls the lifting and lowering of the rod 13 so as to be positioned at the upper standby position is housed in the box 9 and configured as a unit. This air cylinder is provided with a cylinder control means 15, and the rod 1
3 is held at a standby position, and is lowered after suction to stop the rod 13 by detecting that the rod 13 has descended to a position where the front edge 11a of the suction cup 11 is flush with the work receiving surface 3c by the rod position sensor 14. .

[0008] The operation of the work positioning apparatus thus configured is as follows. The suction cup 11 is the work receiving surface 3
When the luggage door outer 1 stacked on the pallet is adsorbed by the robot hand and released along the guide members 2 and 21 in a state of waiting at a position above c,
The suction cup 11 is set on the front edge 11a along the guide surface. In this state, the suction cup 11 sucks the rear surface position of the associated luggage door outer 1 through the suction tube 12 by the suction device. Normally, the plate-shaped work has a tendency to bend downward at the center, so that the plate-shaped work surely comes into contact with the suction cups 11 on the four sides from above, regardless of deformation. The suction force is set to such an extent that the work is not damaged or partially deformed. In response to the suction end signal supplied from the suction device, the cylinder control means 15 lowers the rod 13, and when the rod position sensor 14 detects the lowering of the rod 13 to a predetermined position, the rod 13 is stopped and the sucker 11 is stopped. Is positioned on the same plane as the work receiving surface 3c. Thereby, the luggage door outer 1
Are brought into close contact with a pair of work receiving surfaces 3c of the receiving member with suction cup 10 and a work receiving surface 20a of the receiving member 20.

In the state where the deformation from the reference surface of the luggage door outer 1 is corrected in this way, a sealer is applied, and the luggage door inner is set from above to perform an assembling process. Thereby, the application of the sealer or the assembling work with the inner, which is another work, is performed with high accuracy.

In the above-described embodiment, the air cylinder provided with the suction cup can be versatile by being unitized with the receiving member. However, the air cylinder may be disposed adjacent to the receiving member alone without being unitized. Is also conceivable.

[0011]

As described above, according to the present invention, the suction cup waits at a position slightly higher than the original work receiving surface to adsorb the work, and then retracts to forcefully adhere to the work receiving surface. Even if the work is deformed, the work is reliably set on the work receiving surface, and various machining accuracy in the set state is highly secured, and a machining mistake is avoided. The work is not deformed due to the suction by the suction cup.
