Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier tape useful for accommodating, transporting and storing a large number of small parts such as various electronic parts and precision equipment parts.

[0002]

[Prior art]

 Conventional carrier tapes are long plastic tapes with recesses that are continuously formed at equal intervals. Various electronic components are stored in the recesses, and a cover tape is used by welding to the tape surface. ing.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional carrier tape has a problem that, when an electronic component such as an IC having a lead wire is stored, the lead wire hits the side wall of the concave portion and is deformed due to an impact generated during transportation. Further, in the conventional carrier tape, after the electronic parts are stored, a cover tape is welded to the surface of the carrier tape to prevent the electronic parts from falling. This cover tape is generally used with adhesive applied to the welded surface.However, depending on the amount applied, unbonded parts and adhesive stick-out parts may occur, which may cause the electronic parts to fall off and lead wires to become dirty, leading to electrical continuity. There is a problem that it causes a bad effect such as a defect.

The present invention solves the above-mentioned conventional problems, because the lead wire of the stored electronic component is not bent by the impact generated during transportation, and the cover tape is not required. It is an object of the present invention to provide a carrier tape that does not require a cover tape welding process and improves workability of taping processing.

[0005]

[Means for Solving the Problems]

 The carrier tape of the present invention is characterized in that an overhanging plate member is formed on at least one pair of side wall facing surfaces of the recess. This overhanging plate member preferably holds the two sides of the housed electronic component in a sandwiched manner by utilizing the flexibility or elasticity of the overhanging piece provided therein, and holds the electronic component in the concave and upper portions. It can be easily fixed left and right.

Such an overhanging plate-like member is formed, for example, so as to project toward a center from a pair of side walls facing each other in the recess, and an electronic component is applied to the elastic overhanging piece of the plate-like member, It is pushed downward so as to be bent, and the elasticity or flexibility of the bent overhanging piece is used to hold the electronic component in a sandwiched state.

The projecting plate member may be attached to at least one pair of side wall facing surfaces of the recess, and is usually attached to one pair of side wall facing surfaces of the recess parallel to the longitudinal direction of the carrier tape. It may be attached to another pair of side wall facing surfaces, or may be attached to the above-mentioned two pairs of side wall facing surfaces. Further, the overhanging piece of the overhanging plate-like member is attached to an appropriate position above the center of the side wall surface of the recess according to the shape of the electronic component to be stored.

Further, the overhanging plate-shaped member may be integrally formed at the time of forming the carrier tape, or may be separately formed and then attached and attached at a predetermined position later. The overhanging plate member can be molded integrally with the carrier tape by adjusting the meshing of the upper and lower molds when molding the recess. In addition, the holding force of the stored electronic components is performed by making the distance between the tips of the protruding pieces of the protruding plate-shaped member smaller than the size of the electronic component. The overhanging piece can be thickened, widened, or lengthened.

On the bottom surface of the concave portion of the carrier tape, there is provided a small hole for a projecting rod for pushing out the electronic component held in the concave shape from the outside, and it is preferable to provide the small hole in the center.

Materials for the overhanging plate member and the carrier tape include polyvinyl chloride resin, polystyrene resin, polypropylene resin, and thermoplastic resins such as polyethylene terephthalate resin, but they are excellent in flexibility and elasticity. Particularly preferred are polyvinyl chloride resin and polyethylene terephthalate resin. The overhanging plate member may be made of a resin, a metal, a composite material, or the like different from the carrier tape, but it is preferable to use the same kind of resin for molding.

The thickness of the overhanging plate member and the carrier tape is usually preferably 0.2 mm to 0.4 mm, although it depends on the elastic coefficient of the material. If it is less than 0.2 mm, the holding strength is small, and if it exceeds 0.4 mm, it is too large.

【Example】

 An example of the carrier tape of the present invention will be described below with reference to the drawings by taking an electronic component (SOP type) as an example. FIG. 1 is a partial perspective view showing a state where electronic components are stored in the carrier tape of the present invention, and FIGS. 2A and 2B show states before and after storing electronic components in the carrier tape of FIG. It is a schematic sectional drawing shown.

In the carrier tape 1 of the present invention shown in FIG. 1, bulging plate-shaped members 2 and 2 are integrally attached so as to face each other substantially at the center of a pair of side wall facing surfaces of a recess 4. The electronic component 5 is held between the shaped members 2 and 2 by the elasticity of the overhanging pieces 3 and 3. Further, a small hole 6 for a protruding rod for taking out the stored electronic component 5 is provided in the center of the bottom surface of the recess 4.

To store the electronic component 5 in the concave portion 4 of the carrier tape of the present invention, the electronic component 5 is placed between the overhanging plate-shaped members 2 and 2 as shown in FIGS. 2 (a) and 2 (b). By pushing it in from above, the elasticity of the bent overhanging pieces 3, 3 holds the electronic component 5 in a sandwiched manner between the overhanging pieces 3, 3. Therefore, the electronic component does not move up and down, left and right in the recess, and therefore the lead wire of the electronic component is effectively protected without hitting the side wall of the recess. In addition, the spacing, thickness, width, and length of the overhanging pieces 3, 3 are changed according to the stored electronic parts to adjust the holding force, so that the electronic parts are prevented from falling out from between the overhanging plate-like members. You don't need a cover tape because you can.

[0015]

[Action]

 The protruding plate-like member formed in the recess of the carrier tape of the present invention holds the stored electronic components in a sandwiched manner, so that the electronic components do not move in the recess.

[0016]

[Effect of device]

 According to the carrier tape of the present invention, the stored electronic components are held in a concave shape and do not move up, down, left or right, so that the lead wires of the electronic components are deformed and become defective due to shocks during transportation. Never. Further, since the cover tape is not required, the welding work can be omitted, so that the workability of the taping process can be significantly improved.
