When the article 12 is taken out (chipped), the holding condition of the article 12 is released; and then, the article 12 is taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure used for storing and transporting articles, a carrier tape having the structure, and a method for using the same. More specifically, the present invention relates to a structure, a carrier tape, and a method for using the same, which are mainly used for storing and transporting small items such as electronic components.

[0002]

2. Description of the Related Art Carrier tapes for transporting electronic parts and the like are:
On high-speed mounting lines, electronic components such as semiconductors, capacitors, resistors, coils, and switches can be transported stably and reliably, and can be handled in reels during storage and transport. I can say. The carrier tape is usually conveyed after components are stored in recesses formed in the tape and then covered with a cover tape to prevent the components from jumping out. Generally, the cover tape and the concave portion forming tape are adhered with an adhesive. However, there is a problem such as variation in the adhesive strength between the concave portion forming tape and the cover tape. For example, when the adhesive strength is insufficient, the cover tape peels off or peels off due to vibration during movement. If the adhesive force is too strong, the component will not peel off from the concave portion forming tape during chipping, or the component will adhere firmly to the tape and a load will be applied during chipping, resulting in deformation of the article. In order to solve this problem, improvements in adhesives have been studied, and a laminated structure has been studied to reduce variations in adhesive strength and to impart conductivity. Also, a method of attaching the cover tape to the concave portion forming tape without using an adhesive has been studied.

[0003]

The cover tape is one of the means for preventing the article from jumping out. However, there has been a problem such as an increase in cost due to an improvement in the cover tape itself and a complicated structure. Therefore, a carrier tape that can prevent the article from jumping out without a cover tape has been desired. For example, Japanese Patent Application Laid-Open No. 10-7184 discloses a structure for preventing an article from projecting by using a cover tapeless structure, but the structure is too complicated to be practical. In addition, in order to stably and reliably convey articles and remove them without deformation, it is necessary that the articles do not rotate or shift in the concave portion of the carrier tape in which the articles are stored. It is effective if the article can be fixed without applying a load. In particular, in the case of a material such as a semiconductor having a lead wire, various studies have been made to prevent the deformation of the lead wire (Japanese Patent Application Laid-Open No. 9-2).
No. 55076). In addition, it is required that the article can be fixed by a simple operation during transportation, and in some cases, the lower surface of the article must be fixed without contacting the carrier.

Further, it is required that chipping can be easily performed. If the tape winding speed is constant in the high-speed mounting line, the component supply speed and the component take-out position are constant. However, if the concave structure of the carrier tape is complicated, it is difficult to safely remove the components housed in the concave portions.For example, in a method of protruding components from below with a pin, the protruded pin may damage the component. However, a chipping method for safely and securely removing components from a carrier tape has not been established yet.

Furthermore, in recent years, from the viewpoint of reducing industrial waste, it has become essential to reuse a carrier tape after it has been used for transportation. Naturally, it is difficult to reuse a carrier tape having a complicated shape. The present invention has been made to meet the above-mentioned demands, and an object of the present invention is to provide a reusable structure and a carrier tape which can be conveyed without using a cover tape. Another object of the present invention is to provide a structure and a carrier tape from which articles can be easily taken out.

[0006]

The structure made of a shape-memory resin according to the present invention is characterized in that it comprises escape prevention means and / or easy removal means. Here, the escape preventing means and / or the facilitating means can have a shape memory function.

Further, the structure made of a shape-memory resin of the present invention has a first form in which a structure in which a concave shape is stored is transformed into a structure for holding an article so that the article does not escape. And a second mode in which the reproduced shape is reproduced as required.

[0008] The shape memory resin structure of the present invention has a first form in which a shape having a grip portion for holding an article so that the article does not escape is stored in the first form, and a shape in which the article is easily taken in and out. It is characterized in that the second form of the state in which the state is released can be taken as needed.

The carrier tape of the present invention is formed by providing a plurality of these structures on a tape. The transport structure of the present invention is characterized by holding and releasing an article by the property of the shape memory resin. The article conveying method of the present invention is characterized by comprising a step of holding the article by the property of the shape memory resin. The article removing method of the present invention is characterized in that the shape memory resin structure is heated to release the holding state on the article, and thereafter the article is taken out.

According to the present invention, an article can be safely transported by a simple operation, utilizing the property of a shape memory resin that reproduces a shape memorized by heating. In addition, since the structure and the carrier tape of the present invention can easily extrude an article by releasing the holding state, the article can be easily taken out, particularly, chipping of an electronic component or the like. Furthermore, the structure and the carrier tape of the present invention heat and deform the deformation and the like generated during use,
Reusable.

Hereinafter, the present invention will be described in detail. Although the structure and the carrier tape of the present invention are formed of a shape memory resin, in the present invention, it is not necessary to form the entire structure (or the entire carrier tape) with a shape memory resin.
The shape memory resin can be used only in the portion of the structure where the concave portion is stored, or only in the portion where the claw structure gripping portion for holding the article is stored, that is, only in a part. Further, it can be formed from a laminated film of a shape memory resin film and a normal film having no shape memory within a range that does not impair the shape memory.
Further, the structure and the carrier tape of the present invention may be formed of a composite material containing a shape-memory resin and a normal resin having no shape-memory property as long as the shape-memory property is not impaired. When a carrier tape is used, a cover tape may be used in the same manner as in the related art for the purpose of more stably holding an article. The structure and the carrier tape of the present invention can contain a normal resin as described above, but can be manufactured without using a vinyl chloride resin from the viewpoint of environmental protection.

As the shape memory resin used in the present invention, for example, various commercially available shape memory resins can be used. For example, polynorbornene shape memory resin, transpolyisoprene shape memory resin, styrene butadiene shape memory resin Resins, polyurethane-based shape memory resins, and the like. In addition, as long as the shape memory is not impaired,
Conductive particles, antistatic agents, antioxidants, ultraviolet absorbers,
Various additives such as pigments and dyes may be contained and coated to impart conductivity, antistatic property, stability with time, ultraviolet opacity, coloring property, opacity and the like. When various additives are mixed with the resin having shape memory properties, the resin can be previously kneaded with the shape memory resin by various kneading machines such as an extruder and a Banbury mixer. In the present invention, when the term "shape memory resin" is used, in addition to the case of the shape memory resin alone, when the shape memory resin is kneaded with a resin having no ordinary shape memory so as not to impair the shape memory, Also refers to the case where additives and the like are kneaded.

In the present invention, the shape of the concave portion is stored in the shape-memory resin, or an engaging portion capable of holding an article, for example, an engaging shape of a claw is stored. In order to form the concave portion, the concave shape may be formed directly from the material of the shape memory resin, but the concave shape may be formed after forming the film once. The thickness of the film-shaped shape-memory resin is appropriately selected depending on the type and use of the articles to be stored, but is preferably from 100 to 500 μm. In the case of shaping the concave shape after forming the film, for example, first, the shape memory resin is extruded from an extruder or hot pressed to form the film once, and then heated using a male and female mold. It is formed into a concave shape by a method such as pressing.

In order to form a resilient engaging shape, a claw shape may be formed directly from a shape memory resin material, or a claw shape may be formed after being formed into a film shape. The thickness of the film is 100 to 100
Preferably it is 500 μm. In the case of forming from a film, a cut is made in a portion where the nail shape of the film is to be formed, and this portion is bent to shape the article so that it can be held. In such a case, the claw part with the notch will be punched out, so if necessary,
For example, a backing film can be attached to the back side of the film in order to completely protect the article.

When the film is formed into a concave shape or an engaging portion shape, it is necessary to process the film in a temperature region where the shape of the concave portion or the engaging portion can be stored. There is no particular limitation. Here, the temperature condition needs to be equal to or higher than the transition temperature of the shape memory resin, but is preferably set at a temperature at which the resin is sufficiently softened from the viewpoint of workability such as fluidity. The carrier tape of the present invention can be wound into a reel.
Further, a guide may be provided on the carrier tape as needed.

When the article was taken out, it was heated at 60 ° C. for 15 seconds, and the recess having a depth of 5 mm was reproduced as the original recess having a depth of 2 mm, so that the part could be easily taken out. Since the concave portion in which the articles are stored has a depth sufficiently larger than the thickness of the articles, the structures in this state can be stacked and stored, or can be transported in a stacked state as necessary. is there.

Example 5 A sheet having a thickness of 300 μm was formed by a hot press using a urethane-based shape memory resin having a glass transition temperature of 75 ° C. Four nail structure grips as shown in FIGS. 6A and 6A were formed on the obtained sheet and heated to a temperature of 120 ° C. to memorize the shape. Next, after cooling to a temperature lower than the glass transition temperature, the four claw structure grips were pushed outward. The article was stored in the center of the four claw structure grips and heated to 100 ° C. to reproduce the stored shape of the claw structure grip and hold the article. By cooling this to a temperature lower than the glass transition temperature, the article can be firmly fixed, so that even if a slight vibration or load is applied during the transport of the article, no displacement occurs. After transporting to the designated place, 1
The article was taken out from the shape memory resin structure by heating to 00 ° C. to soften the grip portion of the nail structure.

Example 6 A sheet having a thickness of 250 μm was formed by a hot press using a urethane-based shape memory resin having a glass transition temperature of 65 ° C. Two pairs of the same claw structure gripping portions are formed on the obtained sheet as shown in FIGS.
Heated to 0 ° C. to memorize this shape. Next, after cooling to a temperature lower than the glass transition temperature, the four claw structure grips were pushed outward. The article was stored in the center of the four nail structure grips and heated to 80 ° C. to reproduce the stored shape of the nail structure grip and hold the article. By cooling this to a temperature lower than the glass transition temperature, the article can be firmly fixed, so that even if a slight vibration or load is applied during the transport of the article, no displacement occurs.
