Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adhesive application method and an apparatus therefor, such as the process of joining a core slider of a magnetic head assembly to a gimbal (plate spring). In particular, the present invention relates to an adhesive application method and apparatus suitable for technical fields such as applying a small amount of adhesive to components in the process of assembling minute electronic components.

[Prior Art] As electronic components become smaller and more precise, each component becomes smaller. As a fastening means for these, fixing with adhesive is widely used. For example, in precision equipment products such as magnetic heads, the amount of coating is very small.

Methods for applying a small amount of adhesive of this type include applying the adhesive to a thin needle tip, checking the adhesion of the adhesive to the needle tip using a microscope, and then applying it onto the target part. , the adhesive 4 filled in the adhesive reservoir 2 as shown in FIG.
Dip the applicator pin 7 in it, apply adhesive to the tip of the pin,
There is also a method of transferring and applying the adhesive onto the target part 8, and a method previously proposed by the present inventors, although not well known, is to fill the adhesive reservoir 2 with adhesive and then apply the adhesive from the adhesive reservoir 2. Cut off the excess adhesive 4 that has protruded from the board (drawing omitted)
There is also a method of keeping the amount of adhesive filled in the adhesive reservoir 2 constant by cutting it off and removing it.

Note that a coating method using this type of adhesive reservoir 2 and coating pin 7 is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-268.
No. 375 can be mentioned.

[Problems to be Solved by the Invention] Although the prior art mentioned above has been devised in terms of applying a high viscosity adhesive in a fixed amount, it has the following problems.

In other words, in the case of the applicator pin as shown in FIG. When the depth of the adhesive 4 filled in the reservoir 2 changes, the applicator pin 7
The depth to which the product is immersed changes, and the amount of coating changes, resulting in uneven coating amounts. Furthermore, adhesives tend to harden over time, even though they are originally intended for this purpose. When handling adhesives with such properties, in addition to the pins, there are also parts that come into contact with the adhesive, such as a scraping plate (not shown) and an adhesive reservoir 2, but the adhesive 4 that adheres to these will be removed over time. 1. It will harden and if left unattended, it will stick to the slotting board and adhesive reservoir 2. However, there was a problem that it stopped working.

In order to avoid this problem, it is necessary to make these parts disposable or to clean them at appropriate intervals, but if the structure allows for this, there is a problem that the device becomes complicated and becomes impractical.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to solve these conventional problems, and the first object is to provide an improved application method that eliminates the need to dispose of scraping plates and expensive adhesive reservoirs. The purpose of this invention is to provide a coating device suitable for carrying out this coating method.

[Means for Solving the Problems] In order to achieve the above object, the present inventors have obtained the following knowledge as a result of various experimental studies.

That is, first, it was decided to eliminate the adhesive reservoir 2 and replace it with the container itself for the adhesive 4.

Second, the idea is to use the adhesive reservoir 2 and a slotted plate to make the thickness of the adhesive 4 in the adhesive reservoir 2 constant, thereby making the adhesive nest that adheres to the pin constant. Then, by activating an actuator attached to the adhesive container or existing from the beginning, the adhesive is pushed out from the discharge port, its surface position is measured, and a pin is stabbed at a fixed position at that position. I tried to get the same effect.

That is, until now, the thickness of the adhesive in contact with the pin was determined mechanically by the depth of the recess in the adhesive reservoir 2, but the pin is inserted a predetermined amount based on the surface of the adhesive measured H1. Thirdly, the position of the surface of the adhesive can be detected and measured by an imaging measuring device such as a television camera placed on the side.

The present invention was made based on such knowledge,
Specific examples of means for achieving the objectives are listed below.

The first object of the present invention is to: (1) push out the adhesive to the outlet 1 of the container by reducing the volume of the container which has an outlet at one end and is filled with adhesive; , detect the position and shape of the surface of this extruded adhesive, measure H1, and control the movement mechanism of the pin so that the amount of insertion of the pin into the adhesive is constant. and then a step of pulling out the pin and transferring and applying the adhesive to the target part. A step of extruding the adhesive to the outlet of the container by reducing the volume of the container filled with the adhesive, and inserting a first pin into the extruded adhesive to deposit a predetermined amount of the adhesive. The process of relaying the transfer to a temporary sample stand, detecting and measuring the position and shape of the surface of the adhesive transferred to this temporary sample stand, and ensuring that the amount of insertion of the second pin into the measured adhesive is constant. An adhesive comprising the steps of: controlling a moving mechanism of the second pin to insert the second pin; and then pulling out the second pin and transferring and applying the adhesive onto the target part. This can be achieved using the following coating method.

The second purpose is to: (3) provide a container having one discharge port at one end and filled with adhesive; and a container in which the adhesive is pushed out to the discharge port of the container by reducing the volume of the container. An actuator, a means for detecting the position of the surface of the adhesive pushed out to the discharge port and measuring H1, and adhering the adhesive pushed out to the discharge port, and transferring and applying this adhesive onto the target part. An adhesive applicator comprising a pin and a mechanism for moving the pin is used to apply the adhesive described in (4), 1 to the target part and transfer the adhesive to the target part and the pin to be applied. By the adhesive applicator according to the above (3), which comprises adding to the moving device a relay means for temporarily transferring the adhesive and a means for detecting and measuring the position of the surface of the temporarily transferred adhesive. ,
(5) As a means for detecting and measuring the position of the surface of the adhesive, a first pin is inserted into the adhesive pushed out from the discharge port, and then pulled in a stringy state until the adhesive is removed. A means for detecting and measuring the position and shape of the adhesive, and a means for inserting while controlling the position of a second pin that adheres, transfers, and applies the adhesive into the adhesive pulled up into a stringy state. With the adhesive coating device described in item 1 (3),
and (6) means for detecting and measuring the position and shape of the adhesive attached to the tip of the pin, and the time, speed, and acceleration of the pin for transferring and applying the adhesive onto the target part. This is achieved by the adhesive applicator described in item 1 (3), further comprising a control means.

[Effect] The adhesive container is filled and stored with adhesive.

The actuator displaces a portion of the container to reduce its volume, thereby pushing out the adhesive contained in the container from the discharge port. Or pump it up from the spout.

The means for detecting and measuring is the surface position of the adhesive at the discharge point [1], the surface position of the adhesive transferred from the discharge port to the temporary sample stand, or the surface position of the adhesive attached to the pin. It also detects the position and shape and gives instructions.

The pin moving mechanism deposits adhesive on the pin and moves and moves it into a predetermined position for transferring and applying it to the target part.

In this way, the pin is moved to a location where the surface position of the adhesive is known and the pin is pushed in, so the desired amount of adhesion can be achieved depending on the length of the pin in contact with the adhesive. Adhesive transfer and application can be performed stably.

In addition, all the pins in the above embodiments need to be cleaned or replaced at appropriate intervals because the adhesive softens and does not stick, but the structure shown in FIG. 9 should be used. This saves cleaning and replacement.

The pin 18 of this embodiment is used for transferring and applying adhesive by sequentially pulling out a fixed length of a metal linear part 61 such as a wire (or a resin fibrous member such as plastic). The linear part set 61 is wound around the ram 62 and held by the vibro 5.

After transferring and applying the adhesive one or more times, the cutter 63 cuts the adhesive-attached portion of the linear member 6 used as the pin 18, and the line feeding mechanism 64 is rotated to cut the line to a certain length. Send out the shaped member 6]-. As a result, the pin is regenerated and a new pin 8 can be used for the next transfer or application of adhesive, and it is also possible to save the effort of cleaning and replacing the pin.

[Effects of the Invention] According to the present invention, since the depth at which the pin is pushed into the adhesive can be freely and reliably set, a stable amount of adhesive can be transferred.

Furthermore, since the amount of push-in of the pin can be freely set, a different amount of adhesive can be transferred for each operation.

Furthermore, since the amount of adhesive attached to the pin can be measured, the time, speed, and acceleration during transfer and application can be controlled to provide a stable amount of adhesive transferred.

Furthermore, by measuring the diameter of the adhesive after transfer,
It is possible to obtain a stable adhesive transfer amount that is strong against various changes in external and internal conditions, and it can also be expected to play a role in preventing equipment failures and malfunctions.
