Description

[Detailed explanation of the idea] This invention relates to an apparatus for manufacturing a multi-needle electrode recording pen.

In particular, Patent Application No. 59203 filed on May 24, 1970 by the same applicant (% opening/closing 5l-8531
Regarding the apparatus for manufacturing a multi-needle electrode recording pen described in the patent application with the title of the invention as "Multi-needle electrode recording pen and manufacturing method thereof" in 0), the case is used in the manufacturing method of the multi-needle electrode recording pen. This invention relates to improvements in manufacturing equipment.

In a multi-needle electrode recording pen, a large number of needle electrodes are arranged with small gaps, and a signal voltage is sequentially applied to each needle electrode to perform recording.

In order to prevent the needle electrode that performs the recording operation from being worn out due to electrochemical reactions, etc., a noble metal material that is not affected by electrochemical reactions is used.

However, since precious metal materials are very expensive, it is desirable to make the length of the needle electrode as short as possible from the viewpoint of manufacturing cost.

Conventional multi-needle electrode recording pens are manufactured by molding and fixing a large number of needle electrodes arranged in parallel with insulating material, and connecting one lead wire to each needle electrode to supply a signal. It had been.

Therefore, the length of the needle electrode cannot be shortened beyond a certain limit, and the manufacturing cost tends to be high.

Furthermore, since it takes a long time to connect the lead wires, mass production is extremely difficult.

In order to solve these technical problems, the applicant has proposed a multi-needle electrode recording pen and its manufacturing method as described in the above patent application.

Hereinafter, first, an apparatus for manufacturing a multi-needle electrode recording pen described in the above patent application will be described.

Figures 1 to 3 show the manufacturing apparatus described in the above patent application.

FIG. 4 shows the completed multi-needle electrode recording pen.

In FIG. 1, reference numerals 1 and 2 are needle electrode arrangement stands, and on the arrangement stands 1 and 2, there are many thin grooves 3 and 3 in parallel to the edges.
...... is provided.

Then, the array tables 1 and 2 have respective narrow grooves 3, 3...
are arranged in advance so that they are located on the line.

The needle electrodes 4, 4, . The needle electrodes 4, 4, . . . arranged in an array are pressed by the pressing plate 5.

Therefore, each of the needle electrodes 4゜4... is held between the pressing plate 5 and the arrangement table 1, and as a result, when the arrangement table 2 is removed, each of the needle electrodes 4゜4... is held with one end protruding from the narrow groove of the array table 1 as shown in FIG.

After sandwiching each of the needle electrodes 4, 4, . . . as described above, the insulating substrate 6
A needle electrode 4 on which metal foils 1, 7, . . . are arranged.
4. The printed wiring board 6 with the same spacing as each metal foil? , 7... are arranged so as to be in contact with each needle electrode.

Solder is applied to the surfaces of the metal foils 7, 7, . . . in advance.

Therefore, after arranging the needle electrode and the substrate 6 as shown in FIG. 3, when the contact portion between the needle electrode 4 and the metal foil 7 is heated, the solder on the metal foil 7 melts and the needle electrode 4 and the metal foil 7 are heated. to fix.

Various methods can be used to melt the solder; for example, a method of melting the solder by irradiating it with a beam-shaped heat ray may be used.

After fixing the needle electrode 4 and the metal foil 7, when the pressing plate 5 is removed and the needle electrode 4 is taken out from the arrangement table 1, the needle electrode 4 and the metal foil 7 are placed on the substrate 6 as shown in FIG. A state in which each is fixed is obtained.

Then, the entire bonded group between the needle electrode 4 and the metal foil I is molded with an insulating material to form the outer body of the recording pen.

In the conventional device described above, needle electrodes 4, 4, . . . are arranged in narrow grooves 3, 3, . When removing the arraying table 2 after doing so, several needle electrodes 4 may come off from the arraying table 1 due to the frictional force generated between the needle electrodes 4 and the arraying table 2.

Also, when fitting the insulating substrate 6 between the needle electrodes 4, 4, . There were drawbacks.

This invention aims to eliminate these drawbacks.

Figures 5 and 6 show an embodiment of this invention.

In order to manufacture a multi-needle electrode recording pen, first the thin grooves 3, 3
An arrangement table 11 having... is fixed to an elevating table 12.

The lifting table 12 has two projections 13, and the arrangement table 11 has two holes corresponding to these projections 13, so by fitting the arrangement table 11 into these two projections of the lifting table 12, Fix it.

A ready state in which the array table 11 is fixed to the lifting table 12 is depicted by a solid line.

A spring support rod 14 is fixed to the lifting platform 12.

The side plate 17 is held by a spring support rod 14 passed through a hole 18 made in the side plate.

A spring 16 is suspended between the spring support rod 14 and another spring support rod 15 provided on the arrangement table 10, and the lifting table 12 is normally pulled downward.

One end of an arm 19 is held on the side plate 17 with a screw 20.

The other end of the arm 19 is held by a fixture 21 provided on the arrangement table 10.

The arm 19 has a structure in which it can freely rotate around the screw 20 and the fixture 21 as fulcrums.

A side plate support plate 22 is attached between the two side plates 17.

This support plate 22 is provided with a hole 23 at its center.

A screw hole is cut on the array stand 10 corresponding to this hole 23.

In order to raise the array table 11 and align it with the top surface of the array table 10, insert the handle screw 24 into the screw hole and attach the side plate support plate 2.
This is done by pressing down on 2.

When the side plate support plate 22 is pushed down, the side plate 17
The spring support rod 14 rotates clockwise using the spring support rod 14 as a fulcrum.
The lifting table 12 is raised along the vertical wall of the array table 10 by applying an upward force to the table.

Since this operation is performed using the threaded screws 24, the top surfaces of the arrangement stands 10 and 11 can be accurately aligned.

This state is shown by a broken line. After aligning the top surfaces of the array tables 10 and 11, the needle electrodes 4, 4, etc. are arranged in the narrow grooves 3, 3, etc., as shown in FIG. When the single screw 24 is loosened after pressing with the pressing plate 5, the lifting platform 12 is lowered because the spring 16 always applies a downward force to the platform 12, and at the same time, the side plate is rotated using the screw 20 as a fulcrum. Since it rotates clockwise, the side plate support plate 22 rises by the amount that the single screw 24 is loosened.

After lowering the lifting table 12 as shown by the solid line in FIG. 5, pull the array table 11 toward you and remove it.As shown in FIG. 12 along the two protrusions 13 and raise the lifting platform by the same operation as above, as shown in FIG.・
Metal foils 7, 7, which are printed and wired at the same intervals as...
After placing the needle electrode 4 in contact with the metal foil 7, heat the contact area between the needle electrode 4 and the metal foil 7 to catalyze the solder on the metal foil 7, and then connect the needle electrode 4 to the metal foil 7. The state shown in FIG. 4 can be obtained by fixing to the surface.

As mentioned above, according to this invention, the needle electrodes 4, 4...
The array table 11 can be removed without applying any frictional force to the needle electrodes 4, 4...
It is an object of the present invention to provide a manufacturing device for a multi-needle electrode recording pen that can easily mass-produce a multi-needle electrode recording pen consisting of a recording pen that is difficult to handle due to its small diameter and short length. can.
