Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a band for packaging small parts, and more particularly to a packaging material called a carrier tape which is used for packaging small parts such as electronic circuit parts. .

[0002]

2. Description of the Related Art Carrier tapes are widely used as a packaging technology for electronic components. The following technology is known as a specific structure of the carrier tape. A large number of through holes are formed in the main tape made of paper or synthetic resin at intervals along the longitudinal direction. A bottom tape made of a synthetic resin film or the like is attached to the back surface of the main body tape to close the bottom surface of the through hole, thereby forming a recess for accommodating electronic components. Carrier tape of such a structure, after inserting electronic components into the housing recess, a cover tape made of a synthetic resin film or the like is stuck on the upper surface of the main body tape to close the housing recess, and the carrier tape housing the electronic components is removed. It is transported and stored in a state of being wound in a reel shape. When the electronic component is used, the cover tape is peeled off, and the electronic component is taken out from the housing recess.

As a method of manufacturing a carrier tape having the above-described structure, a wide main body tape having a width corresponding to a plurality of carrier tapes is prepared, and a large number of through holes serving as recesses for accommodating each carrier tape are provided in the main body tape. And cutting at the same time for one main body tape. Since the above-mentioned perforation and cutting can be performed simultaneously or continuously by one processing apparatus, efficient production becomes possible. The bottom tape is prepared in such a manner that a tape coated with an adhesive on one side in advance is wound in a reel shape.

[0004]

As described above, when the bottom tape is manufactured in advance and wound and stored in a reel shape for transportation and storage, the coated adhesive sticks the tapes together. There arises a problem that it cannot be peeled off. In particular, the above problem is likely to occur when the storage is performed for a long time in a humid environment or a high temperature environment. In order to prevent the wound tapes from sticking to each other, a release agent is also applied to the surface of the tape where the adhesive is not applied, but the number of work steps increases In addition, the material cost of the release agent is increased. Even if the release agent is applied, the same problem occurs when exposed to such a bad environment for a long time.

Further, depending on the combination of the materials of the bottom tape and the main body tape and the type of electronic parts to be packaged, the kind of adhesive that can be used is often limited or the preferred adhesive is often different. Then,
It is necessary to manufacture in advance the bottom tape coated with various adhesives according to the application, and it takes time and effort to manufacture, and it also takes time to store the manufactured bottom tape of various types. Become. Infrequently used varieties
The problem of sticking of the tapes due to long-term storage is also likely to occur. Therefore, an object of the present invention is to solve the above-mentioned problems relating to the adhesive as a small component packaging band such as the above-mentioned carrier tape for electronic component packaging, thereby facilitating the production and handling of the bottom tape. Another object of the present invention is to improve the productivity of the strip for packaging small parts.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a method of manufacturing a small component packaging strip, comprising the steps of manufacturing a strip having a plurality of recesses for accommodating small components arranged at intervals along a longitudinal direction. And including the following steps. (a) running a band-shaped main body tape having a width corresponding to a plurality of the band members; (b) a step of perforating a through hole at a position to be the accommodation recess of each band material and cutting the main body tape for each individual band material with respect to the running main body tape;

(C) running a band-shaped bottom tape having a width corresponding to a plurality of the band members. (d) a step of cutting the bottom tape into individual strips with respect to the running bottom tape. (e) A step of applying an adhesive to one side of the running main body tape or the running bottom tape before or after the step (b) or the step (d). (f) After the step (e), the bottom tape cut in the step (d) and the main body tape cut and cut in the through hole in the step (b) are allowed to run together by superposing the main body tape. Forming one end of the through hole with a bottom tape to form the housing recess, and bonding the bottom tape and the main body tape with the adhesive to obtain a small component packaging strip.

A specific configuration will be described. [Small Parts] In addition to various electronic parts conventionally packaged in a carrier tape, small parts such as precision mechanical parts and medical supplies having the same transport characteristics as electronic parts are applied.
Usually, the size of the small component is preferably such that the maximum dimension is about several mm or less, but the maximum dimension larger than that may exceed several cm. [Main body tape] The same material as the main body tape in a normal carrier tape is used. Specifically, a tape material composed of a single layer or multiple layers such as paper, nonwoven fabric, synthetic resin, and synthetic resin foam is used. In the case where the small component is an electronic component or the like that refuses to be charged, a tape material subjected to an antistatic treatment is preferable. To facilitate disposal of packaging materials,
Materials that can be incinerated or landfilled are preferred. Renewable materials are also preferred.

The thickness of the main body tape is set according to the dimensions of the small parts to be packaged. In order to package the small parts so that they are not exposed to the outside, a main body tape that is thicker than the small parts is required. Specifically, the thickness of the normal main body tape can be set in the range of 0.5 to 10 mm. As the main body tape, a tape having a wide width corresponding to a plurality of strips to be manufactured is prepared. Usually, one having a width of 10 to 20 lines is used. Also, it is convenient to prepare in a state of being wound in a reel shape for handling such as transportation and storage.

[Bottom Tape] The same material as that used for the bottom tape in a normal carrier tape is used. Specifically, the same tape material as the main body tape is used. In order to impart charging property to the bottom tape, a charging treatment can be performed on the surface. As long as the bottom tape has the strength and durability enough to hold small parts, the thinner the tape is, the thinner the entire strip can be. The thickness of a normal bottom tape can be set in the range of 10 to 500 μm. As with the main body tape, a bottom tape having a wide width corresponding to a plurality of strips to be manufactured is prepared. It is preferable to prepare in a state wound in a reel shape.

[Running of Tape] The main body tape and the bottom tape are run in the longitudinal direction by using running means similar to a usual carrier tape manufacturing technique. Normally, pull out the tape wound on a reel from one end,
After each manufacturing process, the tape is run by winding the manufactured band material. By overlapping the running paths of the main body tape and the bottom tape vertically and joining them together, the main body tape and the bottom tape can be bonded together with an adhesive interposed therebetween.

[Through hole] A through hole having a size and shape corresponding to the size of a small component to be packaged is formed in the main body tape. A large number of through holes are arranged at intervals along the length direction of the main body tape. The through hole becomes the accommodation recess. In the wide body tape described above, a plurality of rows of through-holes are formed because the accommodating recesses are arranged for each band material. Drilling of the through holes can be performed using a normal press working device or a punching device. Specifically, a through hole is formed by intermittently punching out a running main body tape with a punching type corresponding to the shape of the through hole.

In the main body tape, a sprocket-shaped feed hole can be formed in addition to a through-hole serving as a housing recess. The feed holes can be arranged on one side or both sides of the through-hole serving as the accommodation recess. [Cutting] A cutting technique for a normal paper or a tape material made of synthetic resin is applied. When cutting the main unit tape,
If the above-mentioned press working apparatus incorporates a cutting blade type for cutting the main body tape into individual strips together with the punching die for forming the through hole, the punching and cutting of the through hole can be performed simultaneously or continuously. In one step.

In the case of the bottom tape, the running bottom tape is automatically cut even if a slitter blade or the like is merely arranged on the path of the bottom tape. [Adhesive] The same adhesive as that of a normal carrier tape is used. However, in the present invention, it is not necessary to store the adhesive-coated bottom tape in a wound state for a long period of time, so that it is not necessary to limit the adhesive in consideration of the sticking problem during storage. As the adhesive, a curable adhesive that cures within a certain period of time after application can be used. When a curable adhesive is used, it is necessary to bond the main body tape and the bottom tape before curing. It is also possible to use a hot-melt type adhesive which exhibits adhesiveness by being coated and then dried or cooled and solidified, and then heated. An adhesive that exhibits adhesiveness when irradiated with radiation such as ultraviolet rays can also be used. Adhesive adhesives that adhere by adhesion without being cured can also be used. In the present invention, the adhesive refers to an adhesive in a broad sense including an adhesive and a pressure-sensitive adhesive in a narrow sense.

Specific components constituting the adhesive include dextrin, starch, vinyl acetate, polyvinyl alcohol, polyethylene, polypropylene, synthetic rubbers, and the like, and mixtures and copolymers of these components are also used. To apply the adhesive, a liquid adhesive is used. The adhesive can be applied by adjusting the viscosity with water or a solvent.
At room temperature, the coating can be performed in a state where the solid adhesive is melted by heat. The adhesive may be applied to at least one of the bonding surfaces of the main body tape and the bottom tape.
Of course, both may be applied.

As a method and an apparatus for applying an adhesive, an ordinary technique for laminating tapes can be applied. For example, techniques such as an air knife coater, a doctor knife coater, a roller coater, a reverse coater, and a gravure coater can be applied. The application of the adhesive can be performed on the wide-width main body tape or bottom tape before the perforation or cutting of the through-hole, or can be performed after the cutting. [Lamination] Cut the bottom tape. The main body tape is cut out by drilling through holes. The adhesive is applied to the bottom tape or the main body tape.

If the adhesive exhibits an adhesive strength in a coated state, the bonding step can be performed as it is. In the case of an adhesive that does not develop a sufficient adhesive force only by being applied, a step of developing an adhesive force is performed. Specifically, in the case of a hot-melt adhesive, hot air blowing or heating by a heater is performed. Ultraviolet rays may be applied, moisture may be applied, a solvent may be sprayed, or a chemical agent that chemically develops adhesiveness may be applied. The main body tape and the bottom tape are run so as to overlap with each other in a state where the adhesive has developed an adhesive force. One end of the through hole of the main body tape is closed by the bottom tape to form a housing recess, and the main body tape and the bottom tape are bonded to each other by the action of an adhesive.

If the main body tape and the bottom tape are pressed against each other, the adhesion is ensured. Specifically, one tape can be pressed against the other tape, or both tapes can be pressed between a pair of rollers. After laminating the main unit tape and the bottom tape, in order to accelerate the curing of the adhesive, heat and heat the heater to evaporate the moisture and solvent contained in the adhesive, or to irradiate radiation such as ultraviolet rays. And can accelerate the curing reaction. The small component packaging strip with the main body tape and bottom tape bonded together is collected as it is and transported and stored. Usually, it is collected in a state wound around a reel. It can also be collected in a traverse winding state in which the winding position is swung right and left like a peg.

Subsequent to the laminating step, a part inserting step of inserting small parts into the accommodating recesses of the strip is performed.
It is also possible to perform up to the packaging operation of small parts on a series of lines, for example, by performing a step of attaching a cover tape on the accommodation recess.
