Description

DETAILED DESCRIPTION OF THE INVENTION Regarding the fitting device of the present invention, its first purpose is to be able to continuously fit a large number of pins with different fitting conditions, especially minute pins;
The second purpose is to enable a large number of pins to be connected to several boards in succession.

Conventional pin-setting devices of various types and numbers are as shown in Fig. 1, in which 1 is a unit fixed to a base, and a snap 2 detachably attached to the tip of this unit rotates and descends. When the pin 5 reaches the bottom dead center adjusted by the stopper 3, it is held by the holding member 4, so that the pin 5 is fastened to a plate 6 which is a cover.

However, in this type of device, the fitting unit 1
is fixed to the base and cannot be moved, so in order to hold a large number of pins of various types, the holding member 4 must be moved by hand, or the holding member 4 must be replaced each time the type of pin changes. It was difficult to work with, was irrational, and had a limit in how many different types of pins could be inserted. In addition, with this type of device, each time a different pin is to be set, the bottom dead center of the snap 2 and the lowering time must be adjusted by adjusting the timer built into the stopper 3 and the unit 1. It was hot.

The present invention solves all of the problems of the conventional device at once, and one embodiment thereof will be described below with reference to the drawings from FIG. 2 onwards.

FIG. 2 is a plan view of the rice device of this embodiment,
FIG. 3 is a side view thereof. In the figure, the unit 11 is fixed on an XY table 13 which can be freely moved back and forth and left and right by a numerical control device 12 using a computer. A member called a snap 14 attached to the tip of this unit 11 is attached to a motor 15.
The cylinder 16 is rotated by
It is designed so that it can be moved up and down. As shown in FIG. 5, the lowering end position of the snap 14 is set by a cylindrical stopper 17 which is threaded on the inside. Adjustments are made by moving in the direction, and the descending time is adjusted by a timer (not shown). The rotary disk 20 that fixes the XY table 13 and the eight holding members 19 is attached to a main body base 21, and a motor (not shown) that intermittently rotates the rotary disk 20 is installed inside the base 21. The above-mentioned numerical control device 12 and the like are built-in. The XY table 13 is moved back and forth and left and right (in the direction of the arrows in FIG. 2) by two pulse motors 22 according to instructions from the numerical control device 12.

FIG. 4 shows details of the holding member 19. This holding member 19 is held on a rotating disk 20 in a state where it is suspended by a compression coil spring 23 and is prevented from coming off by a stopper shaft 24. During tightening work, the holding member 19 is lowered by the downward force of the snap 14 against the force of the spring 23 until it comes into contact with the holder 25 of the locking unit 11, and in this state, the various locking pins 26a to 26d are held in place. Plate body 2 which is
Put it on 7. A snap pin 26 is attached to the holding member 19.
Bushes 28a to 28d that hold the pins a to 26d are press-fitted through spacers 29 that finely adjust the height of the pins.

FIG. 5 shows details of the stopper 17 that determines the lowering end position of the snap 14. When the lever 30 connected to the snap lowering adjustment cylinder 18 shown in FIG.
The lowest position of the snap 14 is determined according to the screw pitch cut inside the stopper 17 and the rotation angle.

Next, the overall operation of the above embodiment will be explained. First, the pin 26 and the cover 27 are mounted on the holding member 19, and when a start signal is input to the device, the rotary disk 20 rotates 1/8 and stops. Next, according to instructions from the numerical control device 12, the XY table 13 to which the locking unit 11 is attached is moved to the locking pin 2.
The above unit 11 in any one of 6a to 26d
The snap 14 is moved to the opposing position by the drive of the pulse motor 22, and the lowermost position of the snap 14 suitable for the pin is then set by the stopper 17 by the action of the cylinder 18. When this is completed, the snap 14 is rotated and lowered to fit the pin into the plate. When the time set by the timer has elapsed, the snap 14 is raised to its original position by the drive of the cylinder 16, and the unit 11 is moved to the next desired pin position. This cycle is repeated to fit a large number of pins onto one plate. When all the fitting work for one plate is completed, the turntable 20 rotates 1/8 again to bring the next plate below the unit 11. This cycle is repeated to progress the work on a plurality of plates.

As explained above, according to the rice device of the present invention, the following effects can be obtained. That is, (1) Since a large number of eye pins of different shapes can be inserted continuously and uniformly under conditions suitable for each pin, the quality of the eye is stable.

(2) A large number of pins of various types can be inserted into multiple covers continuously.

(3) The number of coverings and pins can be changed freely according to the production volume, and effects such as the effective use of the locking device can be obtained.
