Description

The present invention relates to a nut set combination device for forming a nut set.

For example, in a processing apparatus for processing a semiconductor wafer or the like, a prismatic aluminum frame is assembled as disclosed in Patent Document 1 or Patent Document 2 to form an outer frame of the apparatus. When assembling the aluminum frame in this way to make the outer frame of the device, the aluminum frames are crossed and the connecting tool is screwed to the crossed portion. That is, the aluminum frame has a groove (for example, a groove having a substantially C-shaped cross section) formed on the outer surface in the extending direction of the aluminum frame, and a nut that is loosely fitted is inserted into the groove to insert a nut. It is possible to fix the connecting tool with screws in the screw holes of.

The nut is formed to have a width slightly narrower than the groove width so that the nut can move freely in the groove extending direction. In the assembly work of the aluminum frame, it is desired to fix the nut at a predetermined position in a predetermined groove and screw the screw through the through hole formed in the connector to fix the screw of the connector. However, since the nut moves freely in the groove, it may be necessary to search for the nut in the groove, which may take time and effort for assembly work.

Since we want to fix the nut in a predetermined position in the groove, we intervene a resin frame with elasticity in the slight gap between the width of the nut and the width of the groove, and the frictional force acting between the resin frame and the inner surface of the groove. Fixes the nut in place. That is, a nut set in which a resin frame is fitted to the nut is formed, and the nut set is inserted into the groove.

The resin frame is formed in an annular shape so as to surround the outer circumference of the nut, and when the nut set is inserted into the groove, the resin frame is interposed between the nut and the groove in the groove, so that the operator can force the force. The nut set can be moved by applying, but the nut set without force cannot move freely due to the frictional force between the resin and the inner surface of the groove, so the nut set can be moved freely in the groove. Eliminates the problem, making it easier for the operator to attach the connector, and shortening the work time for assembling the aluminum frame.

However, it is necessary for the operator to perform the nut set combination work of fitting the resin frame into the nut, and this combination work takes time.
Therefore, in the aluminum frame assembly work, there is a problem that it is desired to eliminate the nut set combination work performed by the operator.

Hereinafter, a case where the nut 80 and the resin frame 82 are combined to form the nut set 85 by using the nut set combination device 1 according to the present invention shown in FIG. 1 will be described.

When the motor 222 of the nut drum rotation mechanism 22 rotates the rotation shaft 220 in the clockwise direction when viewed from the −Y direction side, the nut drum 20 rotates in the same direction. As a result, the nuts 80 housed in the nut drum 20 are discharged one by one from the nut drum through hole 207 formed in the outer wall 203 of the nut drum 20 to the outside of the nut drum 20 and fall onto the nut rail 50, and further. , The nut rail 50 slides down on the nut rail 50 in a state where the orientation is adjusted to a predetermined direction.

In parallel with the nut drum rotation mechanism 22 rotating the nut drum 20, the motor 77 rotates the nut mounting portion rotating shaft 700 in the clockwise direction when viewed from, for example, the −Y direction side via the motor gear 773 or the like. In accordance with this, the nut mounting portion orbiting table 701 rotates at a predetermined rotation speed when viewed from the −Y direction side, and the plurality of nut mounting portions 702 orbit around the nut mounting portion rotating shaft 700. Then, the nut 80 that has slid down on the nut rail 50 is placed on the nut mounting portion 702 located on the lower end side of the nut rail 50 in a state where, for example, the lower surface 806 is exposed.
The rotation speed of the nut drum 20 is kept constant by the control of the motor 222, and the rotation speed of the nut mounting portion orbiting table 701 is kept constant by the control of the motor 77, so that the nut from the nut drum 20 is kept constant. By the time the new nut 80 that has fallen on the rail 50 slides on the nut rail 50 and arrives at the nut mounting part circuit stand 701, the nut mounting part next to the nut mounting part 702 on which the nut 80 is mounted first The 702 is positioned on the lower end side of the nut rail 50, and the operation of mounting the new nut 80 on the nut mounting portion 702 is repeated.

Resin frames 82 are supplied one by one. That is, the motor 323 of the resin frame drum rotation mechanism 32 rotates the rotation shaft 322 in the counterclockwise direction when viewed from the −Y direction side, so that the resin frame drum 30 rotates in the same direction.

As the resin frame drum 30 rotates, the plurality of bars 37 arranged inside the resin frame drum 30 and the resin frame drum through holes 307 rotate around the center of the resin frame drum 30. Then, inside the resin frame drum 30, the claw 825 of the resin frame 82 is caught by the bar 37 that circulates from the lower side to the upper side, and further, the claw 825 of the resin frame 82 is caught inside the resin frame drum 30. When the bar 37 moves upward, the resin frame 82 slides down the side surface of the bar 37 along the inclination of the bar 37. Then, as it is, the resin frame 82 is discharged from the resin frame drum through hole 307 connected to the tip end side of the bar 37 in a state where the direction is determined to the outside of the resin frame drum 30. That is, only the resin frame 82, which is caught in the bar 37 and matches the shape of the resin frame drum through hole 307, passes through the resin frame drum through hole 307. Therefore, the resin frame passes through the resin frame drum through hole 307. The direction of 82 is always aligned with a predetermined direction.

The resin frames 82 are discharged one by one from the resin frame drum through hole 307 formed in the center of the outer wall 303 of the resin frame drum 30 to the outside of the resin frame drum 30, and fall onto the upper rail 560 of the resin frame rail 56, and further. , The upper rail 560 slides down on the upper rail 560 in a state where the orientation is adjusted to a predetermined direction. Then, when the resin frame 82 reaches the orthogonal portion between the upper rail 560 and the lower rail 562, the piston mechanism 566 operates to push the resin frame 82 in the extending direction of the lower rail 562, and the resin frame 82 Slides down the lower rail 562.

In parallel with the resin frame drum rotation mechanism 32 rotating the resin frame drum 30, the motor 77 views the resin frame mounting portion rotating shaft 730 via the motor gear 773 or the like in the counterclockwise direction, for example, when viewed from the −Y direction side.

By the time the new resin frame 82 that has fallen from 30 onto the resin frame rail 56 slides on the resin frame rail 56 and arrives at the resin frame mounting portion orbiting table 731, the resin frame 82 on which the resin frame 82 is placed is placed first. The resin frame mounting portion 733 next to the portion 733 is positioned on the lower end side of the lower rail 562, and the operation of mounting the new resin frame 82 on the resin frame mounting portion 733 is repeated.

As described above, the motor 77 rotates the motor gear 773 in the counterclockwise direction when viewed from the −Y direction side, so that the nut mounting portion 702 mounts the nut in the clockwise direction when viewed from the −Y direction side. The resin frame mounting portion 733 rotates around the rotation shaft 700, and the resin frame mounting portion 733 rotates in the counterclockwise direction when viewed from the −Y direction side, which is the opposite direction of the rotating direction of the nut mounting portion 702. It orbits around 730. Then, the nut mounting portion 702 on which the nut 80 is mounted with the lower surface 806 exposed, for example, and the resin frame 82 are mounted with the side on which the claw 825 is not formed, for example, exposed upward.
