Abstract

PURPOSE:To reduce the application time with an instantaneous adhesive and improve the efficiency in assembling work of a magnetic head, by supplying a high-humidity air to a part coated with an adhesive between a head base and a head core. CONSTITUTION:A head core 2 is located at a given position on the top surface of a tip part of a head base 1, and then pressed to supply an adhesive 3 from a nozzle 6. After completing the supply of the adhesive 3, high-humidity air is supplied from a humidifying nozzle 7 to the application site 10 of the head base 1 and head core 2 to harden the adhesive 3 in the above-mentioned application site 10. Thus, the aimed magnetic head is assembled.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to, for example, a magnetic head assembly device, and particularly to a magnetic head assembly device that reduces the time required to bond a head core and a head base. .

[Background of the invention]

The magnetic head used in VTRs etc. is 311f.
As shown in f, a head core 2 is attached to the upper surface of the tip of a head base l using an instant adhesive 3. Conventionally, when assembling the above magnetic head, the fourth
As shown in the figure, after positioning the head core 2 held at the lower end of the head core chuck 5 at a predetermined position on the upper surface of the end of the head base 1 which is clamped to the end of the head base chuck 4, With the head core 2 pressed against each other, instant adhesive 3 is supplied from the tip opening of the nozzle 6 of the adhesive applicator to the bonding position lO of the rad core 2 and the head core 2 to bond both 1 and 2 together. Paste method is used.

Note that the instant adhesive 3 hardens due to moisture absorption, and is heated at high temperatures.
α-cyanoacrylate adhesive is used, which has the property of accelerating curing in high-temperature environments. Due to strict dimensional accuracy,
It is generally carried out in a constant temperature room, and the temperature and humidity are generally kept low. Therefore, it takes a long time (about 10 seconds) from applying the instant adhesive 3 to curing it. If the magnetic head is used before the instant adhesive 3 is sufficiently cured, there is a risk that the head core 2 may become misaligned. Therefore, when developing a highly efficient magnetic head automatic assembly apparatus, the curing time of the instant adhesive becomes an obstacle. In addition, as a document regarding the assembly of conventional magnetic heads, for example, Utility Model Application Publication No. 58-1
There is No. 76221.

[Purpose of the invention]

The present invention solves the above-mentioned conventional problems and provides a magnetic head assembly device that can improve the efficiency of magnetic head assembly work by shortening the time required for bonding the head base and head core with an instant adhesive. There is a particular thing.

[Summary of the invention]

In order to achieve the above object, the present invention is characterized in that a humidification mechanism is provided for supplying highly humid air to the adhesive-applied area between the head base and the head core, for example.

[Embodiments of the invention]

1 and 2 showing embodiments of the present invention will be explained below. In the figure, 7 is a humidifying nozzle, which opens toward the bonding position 10 between the head base 1 and the head core 2, and is formed to supply highly humid air toward the position 10 as shown by the arrow 9. has been done. Reference numeral 8 denotes an exhaust device, which is arranged so as to face the bonding position 10 of the Rad base 1 and the head core 2 with the Rad core 2 in between, and the head base 1 from the humidifying nozzle 8;
It is formed so as to suck the highly humid air supplied to the bonding position 10 with the head core 2 and discharge it to another location. Since everything other than the above is the same as the conventional one, it is indicated by the same reference numerals as in FIG. With the above configuration, after positioning the head core 2 at a predetermined position on the top surface of the tip of the head base 1 in the same manner as in the conventional method, the adhesive application device The adhesive 3 is supplied toward the bonding position 10 from the tip opening of the nozzle 6. Next, when the supply of the adhesive 3 to the bonding position 10 is completed, the nozzle 6 of the adhesive applicator
Even if high humidity air is supplied from the humidifying nozzle 7 toward the bonding position 10 between the head base 1 and the head core 2 as shown in FIG. At the same time, the humidifying nozzle 7 supplies high-humidity air toward the bonding position 10 between the head base 1 and the head core 2 to remove the adhesive 3 at the bonding position 10. Let it harden. The highly humid air supplied to the bonding position 10 is sucked into the exhaust device 8 and discharged to another location.

Therefore, even if the magnetic head is assembled in a room kept at a constant temperature and low temperature, the adhesive is 3 can be cured in a short time, and the highly humid air supplied to the bonding position 10 between the Radbase 1 and the Radcore 2 is sucked by the exhaust device 8 and discharged to another location. It is possible to prevent high humidity air from having an adverse effect on others.

〔Effect of the invention〕

Since the present invention is as described above, the instant adhesive used for adhering the head base and the head core can be cured in a short time with easy operation, and the assembly time of the magnetic head can be shortened. be able to.

Incidentally, instant adhesives have recently come to be used not only for assembling magnetic heads but also, for example, for pickups of video disk players. The present invention can also be applied to those assembly devices.
