Description

  The present invention relates to a reel flange deformation preventing jig, and more particularly, to a reel flange deformation preventing jig capable of preventing the flange from being deformed in the width direction of the reel even when an external force is applied to the flange.

  In recent years, component mounting on a printed circuit board is mainly performed using an automatic mounting apparatus. That is, a reel in which a carrier tape in which components are continuously sealed in the longitudinal direction is wound around a winding core is mounted on an automatic mounting device, and components are sequentially taken out from the reel and automatically printed circuit boards. This is a form of mounting at a predetermined position.

In that case, the reel is wound by a predetermined length around the reel core through a predetermined process. Next, the reel is accommodated in a moisture-proof packaging bag made of plastic, for example, and vacuum-packed to prevent moisture from the outside.
However, the reel has a structure in which a central winding core and a pair of thin large-diameter flanges are fixed between them. However, a plastic flange does not have much mechanical strength. Since there is a gap between the flanges, the flange may be deformed by atmospheric pressure, and the distance between the pair of flanges may not be able to maintain a predetermined width.

  When the flange is deformed, there is a possibility that even after opening the vacuum-packed moisture-proof packing bag, when the carrier tape is pulled out by the automatic mounting apparatus, it cannot be smoothly taken out. In order to solve such flange deformation of the reel, the following flange deformation prevention jig is disclosed in Japanese Patent Laid-Open No. 2000-128438.

  The reel deformation prevention jig disclosed in the above publication is a jig for preventing deformation in the width direction of the flange in a reel comprising a winding core and a pair of flanges fixed therebetween, Is formed, and the width direction of the peripheral edge of the flange is fixed to prevent deformation.

JP 2000-128438 A

  In the case of the above-described reel deformation prevention jig, the effect of preventing deformation due to external force is surely improved by fixing the flange peripheral portion.For example, the carrier tape is rarely wound up to the outer peripheral portion of the flange, Since it is often half or less, such as when vacuum packed, when an external force inward due to atmospheric pressure is applied to the entire flange, only the core part, the carrier tape part wound around the core and the peripheral part of the flange The part is fixed and has an effect of preventing deformation against external force, but is not fixed between the outer periphery of the carrier tape and the peripheral edge of the flange depending on the length of the carrier tape wound around the core as described above. When a gap is formed and an external force is applied to the whole, the effect of preventing deformation of the flange cannot be exhibited. In particular, when the carrier tape to be wound is short, most of the pair of large-diameter flanges have a space between the flanges, and are deformed inward by an external force, that is, in a direction in which the flange and the flange approach each other.

  An object of the present invention is to provide a reel flange deformation preventing jig that solves the above-described problems and prevents deformation of the entire reel flange inward.

  In order to achieve the above object, in the present invention, there is provided a jig for preventing deformation in the width direction of the entire flange of a reel including a winding core and a pair of flanges fixed with the winding core interposed therebetween. Between the flanges, the shape is such that the entire area from the outer periphery of the carrier tape wound around the core to the peripheral edge of the flange is filled.

According to the present invention, between the winding core and a pair of flanges fixed with the winding core sandwiched between the outer periphery of the carrier tape wound around the winding core and the peripheral edge of the flange, it is possible during vacuum packing, etc. When an inward external force due to atmospheric pressure is applied to the entire flange, it is possible to prevent deformation in the width direction of the entire flange as well as the vicinity of the core and the peripheral edge of the flange.
With this jig, the use of the reel mounted on the automatic mounting apparatus prevents a problem of flange deformation and is extremely effective.

  Hereinafter, embodiments of the present invention will be described in detail. Between the winding core and a pair of flanges fixed with the winding core in between, the carrier tape wound around the winding core has a shape that fills the entire periphery from the wound outer peripheral portion to the peripheral edge of the flange. Here, as the shape of the material between the pair of flanges, the space between the flanges is filled with a semicircular shape made of a material having a strength divided into two parts with a structure that can adjust the inner diameter of the core. Like the carrier tape, and like the carrier tape, the belt tape is continuously wound from the end to the outer periphery of the flange. I will explain things.

  First, an example of a semicircular shape used in two divisions will be described with reference to FIG. The reel A includes a winding core 1 and a pair of flanges 2 fixed with the winding core 1 interposed therebetween. Accordingly, the flanges 2 are opposed to each other while maintaining an interval L corresponding to the length of the winding core 1, and a carrier tape (not shown here) is wound around the flange 2 here.

  The jig B of the present invention shown in FIG. 2 has an outer diameter that is equal to or slightly larger than the outer diameter H of the flange 2 and has a thickness that is equal to the distance L between the pair of flanges 2 facing each other. Shape. The jig B of the present invention fills all gaps between the pair of flanges 2, but the outer circumference of the wound carrier tape and the outer circumference of the flange 2 depend on the amount of the carrier tape wound around the reel A. It is assumed that the interval of changes. Therefore, by having one or a plurality of separation points a shown in FIG. 2, even if the amount of the carrier tape wound around the reel A is variable, the inside of the jig B is separated and removed by the separation points a. By doing so, the entire space between the outer periphery of the carrier tape wound around the core 1 and the outer periphery of the flange 2 can be filled, and deformation of the entire flange, which is the purpose of this jig, can be prevented. .

  FIG. 3 shows an image when the jig B according to the present invention is used for the reel A. The two semicircular jigs B are separated so as to have an appropriate size in order to fill from the outer periphery of the carrier tape to the outer periphery of the flange 2 according to the amount of the carrier tape wound around the core 1 of the reel A. Adjust at the location a and insert between the opposing flanges 2 of the reel A. At that time, by connecting the two semi-circular jigs B by the fixing portion 3, the jig B is prevented from being displaced due to, for example, vacuum packing.

  Next, a description will be given of an example of a winding band shape in which a belt-shaped one is wound continuously from the end of winding of the carrier tape. A carrier tape (not shown here) is wound around the core 1 of the reel A in FIG. It is burned. The carrier tape is rarely wound all the way to the outer periphery of the flange 2, and is often half or less. FIG. 4 shows a belt-shaped flange deformation preventing jig C which is an embodiment of the present invention. Moreover, the usage image of the jig | tool C is shown in FIG. Here, it is assumed that the carrier tape is extremely small and is not shown. The jig C has a belt shape with appropriate elasticity and strength, and is continuously equal to or slightly larger than the outer diameter H of the flange 2 from the end of the carrier tape wound around the core 1. It is rolled up to the point. Thereby, all the gaps between the pair of flanges 2 can be filled.
