The stacking jig includes a pin supplying section that accommodates a plurality of pins having a diameter slightly smaller than the pin holes of the stacking jig in an attitude that can be held by the pin chuck section, and supplies the pins one by one to a predetermined position.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

In FIG. 1, a steel lamination jig 1. has a rectangular and flat plate shape, and has four pin holes 2a, 2b, 2c, and 2d machined with high precision at predetermined positions. The pedestal 3 has approximately the same shape as the lamination jig 1 and has sufficient rigidity. The positioning pins 4a and 4b contact two orthogonal sides of the lamination jig 1. The pushers 5a and 5b press and fix the lamination jig 1 against the positioning pins 4a and 4b, respectively. The pressure parts 6a and 6b and 6c and 6d are arranged outside the four corners of the product=6=layer jig]-, and the loading jig is controlled by pressure jaws 7a and 7b and 7c and 7d provided at their tips, respectively. Pressure is applied to the four corners of tool 1 from the -F direction. The moving mechanism section 8 attaches a slider 9 and moves it to the entire surface of the lamination jig and to the position of the pin supply section 1.4.

The slider 9 is disposed above the pedestal 3 at a predetermined distance, and has a lower mechanism part O fixed to the lower surface thereof and configured to move the pinch part 1 up and down at the lower end. , a fin force 12 is provided at the lower part of the pinchuck portion 1].

The pin supply unit 14 accommodates a plurality of pins 13 having a slightly smaller diameter (approximately minus 10 μm) than the pin holes 2a to 2d of the lamination jig 1 in a posture that allows them to be gripped with fingers, and supplies each pin one by one to a predetermined position. supply to the position.

The pin assembly device configured as described above operates as follows. That is, first, the pushers 5a and 5b are operated on the lamination jig 1 mounted on the pedestal 3,
The lamination jig 1 is pressed and fixed against the positioning pins 4a and 4b. Next, pressurizing parts 6a and 61] and 6
c and 6 (operate 1 to pressurize shows 7a and 7b
7c and 7d pressurize the four corners of the stacking jig 1 from above to correct the warpage of the stacking jig 1 and flatten it.

Next, the pin supply section 14 is operated to supply pins] 3 one by one to a predetermined position 1η. Next, move the moving mechanism section 8 (to move the chuck section 1) to the pin (! (pin 1 of the structure section 14).
3 and operate the fin force 12 of the vertical mechanism section] 0 and the chuck section 11 to transfer the pin 13 from the pin supply section 14 to the fin force 12.

After this, the upper mechanism section 8 is raised and the moving mechanism section 8 is moved.
Then, move the pin 1-3 to the -L position of the pin hole 2a of the laminating jig 1. Next, lower the vertical mechanism section 10 and remove the pin 13.
is inserted into the pin hole 2a of the lamination jig 1, the fin force 12 is opened, and the lower frame structure 10 is raised. This operation is performed sequentially for the pin hole 2b, pin hole 2c, and pin hole 2d, and the pin]-3 is applied to all the pin holes of the laminating jig 1.
