CONSTITUTION:A jig 1 consists of a jig base 2 forming its body and a pin 3 for holding a set number of articles embedded in this base. In addition, the base 2 is made up of the formation of pin holes 2a, push pin leading guide holes 2b for product takeout use and taper surfaces 2c and 2d formed as a precision positioning functional element part. Next, at each set position in an automatic article assembling line, a quantity inspection position, a capping position, etc., the jig 1 is temporarily clamped in an automated manner whereby the precision positioning of the jig 1 and the automatic centripetalism by a taper hole part 3c of each pin 3 both are performed simultaneously. Thus, the jig 1 largely contributes to improvements in productivity.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembly and conveyance jig used for automatically assembling products on an automatic conveyance line. It is possible to lock and hold cylindrical articles in a removable manner, and to ensure precision positioning and automatic centripeting by automatic mechanical means at the automatic assembly set position and automatic quality inspection position on the conveyor line. We now offer an assembly and transportation jig with an ideal configuration, which is equipped with a compressed air injection hole for detecting clogging and air cleaning of assembled finished products, and a push-up bin introduction guide hole for removing dazzling finished products. .

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

1 jig of this invention, 2 jig bases forming its main body
and a set number of article holding pins 3 embedded in the base.
It consists of

The jig base consists of two integrally molded pieces of hard synthetic wood, and has a set number of bottle holes 2a drilled and lined up at regular intervals along the longitudinal direction of the center of the upper wall surface, and a set number of bottle holes 2a arranged in a row in the central longitudinal direction of the upper wall surface. A push-up pin introduction guide hole 2b for product removal is bored at a position sandwiching each of the bottle holes in a plane, and a tapered surface is formed as a precision positioning functional element part in the longitudinal direction on both sides of the upper part.
)c, 2d.

On the other hand, the article holding pins 3Id are made of precision machined metal pins made of stainless steel or other superalloys, and are fitted into each bottle hole 2a of the jig base 2 by pulling out and re-stretching, and standing upright on the base. .

The article holding bottle 3 has a locking function part 3a that automatically locks an article 4 (see FIG. 3) fitted in the bottle, which will be described later, in a detachable manner, and a locking function part 3a that passes through the respective bottle axis parts. compressed air injection hole 31) and an automatic centripetal function section 3 for centering the article.
C (see Figure 3, Rod 4).

In the case of the illustrated example, the locking function part 3a consists of an annular engagement groove formed on the head side of the bottle 5, and the automatic centripetal function part 3C is formed on the proximal opening side of the compressed air injection hole 3b. Furthermore, as a removable fitting means for the article holding bottle 6 into the bottle hole 2a, an annular locking groove 3d (see FIG. 4) is provided on the inner peripheral wall surface of the bottle hole 2a. )
However, annular locking protrusions 3e are integrally formed on the outer periphery of each pin 3.

By press-fitting the pin 3 into the bottle hole 2a from below, the annular locking protrusion 3e fits and locks into the annular locking groove 3d, and the bottle 3 is inevitably locked. is released by hitting the pin 3 in the opposite direction to the press-fitting direction, thereby allowing the pin 3 to be removed. By doing so, when the jig base 2 wears out, only the base needs to be replaced with a new one.
There is an advantage that the expensive bottle 3 can be used repeatedly.The jig 1 having the above configuration is placed on an automatic transport device, for example, a loop transfer, and is automatically transported by nuclear transfer.

During the conveyance process, articles 4 to be assembled as shown in FIG. 3 are fitted into each bin of the jig 1. In this case, the articles 4 are made of a cylindrical body made of synthetic resin or the like. In the case of the illustrated example, a very small diameter through hole 4a is provided in the center of the earthen wall.

The cylindrical article 4 also has an annular engagement step part 4b integrally formed in the middle part of the inner surface for engaging and disengaging with the annular engagement groove 3a of the article holding bottle funnel, and an annular engagement step part 4b integrally formed in the lower end opening edge. In the case of the illustrated example, the ultra-fine article 5 having a needle-like through hole is connected to the ultra-small diameter through hole 4 of the cylindrical article 4.
The cylindrical article 4 is automatically transferred to the article holding bin 3 of the diagnostic jig 1 at the auto-transported cylindrical article automatic setting position of the jig 1 by a transfer or the like. Inserted by means.

At the time of fitting, the annular engagement step portion 4b of the cylindrical article 4 is inserted into the bottle 5.
The cylindrical article 4 is held in a locked state in the bin by removably fitting into and engaging with the annular engagement groove 3a.

In this state, the drilling position of the hole 2b is set in advance so that the outward flange piece 4C at the lower end of the cylindrical article 4 follows at least a part of the push-up bottle introduction guide hole 2b of the jig pace 2. There is.

In this way, when the cylindrical articles 4 are removably fitted and held in all the article holding bins 3 and the nine jig 1 is automatically conveyed to the needle-like article automatic setting position for the next process, Then, the proximal end of the needle-like article 5 is press-fitted into the extremely small-diameter through-hole 4a of the upper cylindrical article 4 of the jig by automatic mechanical means.

As a result, a completed assembled product of the cylindrical article 4 and the needle-like article 5 is obtained, and after the finished product is automatically inspected for clogging etc. at the quality inspection position in the next process, it is transferred to the next capping position. The protective cap 6 is fitted on itself.

As described above, at each setting position, quality inspection position, capping position, etc. in the automatic article assembly line, the jig 1 is temporarily clamped by automatic mechanical means. , 2d automatically performs precise positioning of the jig, and at the same time,
Automatic afterlife is accomplished by the tapered hole filter C of each bottle 3.

In addition, at the quality inspection position, the compressed air injection nozzle is automatically aligned with the air injection hole 3b of each bottle 3 by an automatic machine targeting means. The completed product can be automatically inspected for clogging by blowing out air, and the finished product can be cleaned with air almost simultaneously. The outward flange piece 4C at the lower end of the cylindrical article 4 is automatically and mechanically pushed up by a push-up bin (not shown) to be removed. It has a retention function that allows it to be fitted and locked in a manner that allows it to be fitted and removed freely, a precision positioning function and automatic centripetal function during automatic article setting and automatic quality inspection, as well as a compressed air injection hole and a push-up pin introduction guide hole for removing assembled finished products. It has all the functions necessary for automatic product assembly on automatic transport lines, and greatly contributes to improved maintenance and productivity of the lines.
