Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jig used in an apparatus for manufacturing a multi-needle electrode recording pen.

Conventionally, a multi-needle electrode recording pen is manufactured using a jig shown in FIG.

That is, the arrangement tables 2 and 3 having grooves 1 at minute intervals are adjusted by the lifting table 4 so that the grooves 1 of both are aligned, and then arranged side by side. Note that the semi-fixing mechanism of the lifting platform is omitted. A large number of needle electrodes 5 are arranged one by one in the grooves 1 of the arrangement tables 2 and 3 so as not to be misaligned in the direction of the needle electrodes. When you finish arranging the
The needle electrode 5 is sandwiched and fixed between a pressing plate (not shown) and the arrangement table 2. Next, the elevating table 4 is lowered, the arraying table 3 is pulled out, and a substrate (not shown) coated with metal foil and solder is placed on the elevating table 3 at the same spacing as the needle electrodes positioned on the arraying table 2. The lifting platform 4 is raised until the metal foil comes into contact with the lower end of the needle electrode 5.

After confirming that the needle electrode 5 and the metal foil are in contact,
The contact part is heated to melt the solder on the metal foil, and the needle electrode 5
and fix the metal foil. In the multi-needle electrode recording pen manufacturing apparatus as described above, the needle electrode 5 is made of an expensive noble metal material that can withstand electrochemical reactions. Therefore, in order to reduce the cost, it has to be made short, and a thin and short needle electrode 5 is used. Usually, a needle electrode 5 with a wire diameter of 0.3 mm and a length of five layers is used. In such a case, the above-mentioned needle electrodes 5 are held one by one using tweezers or the like and arranged in the grooves 1 of the arrangement tables 2 and 3, but this work takes a lot of time and the work efficiency is extremely poor. .

This invention has been made in view of the above points.

This invention will be explained in detail below. Figure 2 a, b
, c represent a plan view, a front view, and a left side view, respectively, and FIG. 3 represents a perspective view. The rod-shaped body 6 having an H-shaped cross section is made of synthetic resin, and has a large number of rectangular through holes 7 having a length L and a width L in the central plate. The vertical length L corresponds to the length of the array tables 2 and 3, that is, the length of the needle electrode 5, and the width l is shorter than the needle electrode 5, but is set to include a plurality of grooves 1. A slide groove 8 is provided at the bottom of the center plate,
The slider 9 is moved by moving the knob 10 from left to right. The lower part of the rod-shaped body 6 has a width L that can fit into the width of the groove 1 of the arrangement stands 2 and 3. Hereinafter, the operation of arranging the needle electrodes 5 by the operator using the jig having the above configuration will be explained. Rod-shaped body 6
Insert the slider 9 into the slide groove 8 and stop at the position where the knob 10 hits the rod-shaped body 6. The bottom surface of the through hole 7 is closed with a slider 9, forming a housing. Therefore, the needle electrode 5
The number of needle electrodes 5 is evenly placed in the number of grooves 1 of the arrangement bases 2 and 3, with the needle electrodes 5 facing in the vertical direction L of the through hole 7. By gently shaking the rod-shaped body 6 back and forth and left and right, the front and rear ends of the needle electrodes 5 are aligned, and then the rod-shaped body 6 is fitted into the upper part of the array bodies 2 and 3 so that the through hole 7 is located above the groove 1. When the slider 9 is pulled out after confirming that the needle electrodes are fitted in a predetermined position, aggregates of the needle electrodes 5 are present at various locations on the array tables 2 and 3, and are aligned in the front and rear directions. By pushing this assembly of needle electrodes 5 with your finger, the needle electrodes are supplied to the groove 1 located at the bottom of the through hole 7, and at the same time, the through hole is pushed by the pressing force acting in the arrangement direction of the through hole 7. The grooves 1 located between the arrays 7 are also supplied with needle electrodes. Therefore, the needle electrodes 5 fit into each of the grooves 1,
The excess material is pushed to one end of the arrangement tables 2 and 3 and falls from the end. In addition, the width 1 of the through hole 7 is set shorter than the vertical length L, and when inserting the needle electrode 5 into the through hole 7, it is easy to insert the needle electrode 5 into the through hole 7 by inserting the needle electrode into many holes and lightly shaking the rod-shaped body 6 back and forth and from side to side. The front and rear ends of the needle electrodes can be aligned.

After arranging the needle electrodes in the groove 1, the multi-needle electrode recording pen is manufactured by the above-described operation. As described above, according to the present invention, there is no need to line up small needle electrodes one by one, which simplifies troublesome work and improves work efficiency.
