This application claims the benefit of priority to Japanese Patent Application No. 2019-187895 filed on Oct. 11, 2019. The entire contents of this application are hereby incorporated herein by reference.
The present invention relates to a reel for a taping electronic component package.
Electronic components are mounted on substrates commonly with a component mounter such as one disclosed in JP 2007-115898 A. A component mounter draws a carrier tape, also called a taping electronic component package, from a reel, takes an electronic component out of the carrier tape, and mounts the electronic component on a predetermined position of a substrate.
The carrier tape, as illustrated in FIG. 14 of JP 2007-115898 A, is composed of a tape including multiple recesses, electronic components housed in the respective recesses, and a cover film covering the recesses.
Commonly, a single component mounter mounts multiple types of electronic components on a substrate. Thus, the component mounter is provided with multiple carrier tapes. For example, FIG. 13 of JP 2007-115898 A shows a component feeder including multiple tape feeders that are arranged in the axial direction parallel to the width direction of the tapes, carrier tapes that are fed by the respective tape feeders and that provide respective electronic components, and reels around which the respective carrier tapes are wound.
Each reel for a carrier tape, as disclosed in JP 2015-103775 A, includes a shaft, also called a core, and a pair of flanges each having a greater outer shape than the shaft and provided at respective ends of the shaft.
The widths of the reels for carrier tapes are specified by standards and, in some cases, the widths of reels may be greater than the widths of the tape feeders. In this case, the positions of the reels need to be staggered up and down or forward and backward to make the feeding direction of each tape feeder parallel to the longitudinal direction of each tape in attaching the carrier tapes to the respective tape feeders provided in the axial direction. Thus, attachment of carrier tapes to tape feeders using conventional reels involves a problem of installation space in mounting an increased number of electronic components.
Preferred embodiments of the present invention provide reels for a taping electronic component package that are each able to attach a taping electronic component package to a tape feeder in a small space.
A reel for a taping electronic component package according to a preferred embodiment of the present invention includes a core around which the taping electronic component package is to be wound, a pair of flanges that are located at respective ends of the core and that face each other across the core in an axial direction, and a separating portion that provides irreversible separation of the flanges. The taping electronic component package includes a tape including multiple recesses and electronic components housed in the respective recesses.
Preferred embodiments of the present invention provide reels for a taping electronic component package that are each able to attach a taping electronic component package to a tape feeder in a small space.
The above and other elements, features, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments with reference to the attached drawings.
Hereinafter, reels for a taping electronic component package according to preferred embodiments of the present invention is described.
The present invention is not limited to the following preferred embodiments, and may be suitably modified without departing from the gist of the present invention. Combinations of two or more preferred features described in the following preferred embodiments are also within the scope of the present invention.
Hereinafter, the reels for a taping electronic component package according to the respective preferred embodiments are each simply referred to as the “reel for a taping electronic component package” when no distinction is made therebetween. The reel for a taping electronic component package is also simply referred to as a reel.

As shown in
Each recess 22 houses an electronic component 25. Examples of the electronic component 25 include capacitors, for example, multilayer ceramic capacitors, resistors, inductors, thermistors, and piezoelectric devices.
The core of the reel for a taping electronic component package may have a cylindrical or substantially cylindrical outer shape, for example. As shown in
The first flange and the second flange of the reel for a taping electronic component package are located at the respective ends of the core. The cases where the first flange and the second flange are located at the respective ends of the core include not only the case where the first flange and the second flange are on the respective end surfaces of the core but also the case where they are closer to the central portion of the core than the respective end surfaces.
The first flange and the second flange of the reel for a taping electronic component package define a pair of flanges and face each other across the core in the axial direction. The axial direction herein refers to the direction parallel or substantially parallel to the width direction of the tape defining the taping electronic component package. The first flange and the second flange each have an outer shape larger than the outer shape of the core, and may have an outer shape in a disc shape, for example.
The first flange and the second flange of the reel for a taping electronic component package are each preferably formed from a resin, for example. Examples of the resin of the first flange and the second flange include polystyrene, polyester, acrylonitrile, butadiene, and styrene copolymers. The resin of the first flange may be the same as or different from the resin of the second flange.
The first flange of the reel for a taping electronic component package is preferably joined to a corresponding end of the core or provided monolithically with the core, for example. Similarly, the second flange is preferably joined to a corresponding end of the core or provided monolithically with the core, for example. Accordingly, the core is preferably formed from a resin, for example. Examples of the resin of the core include polystyrene, polyester, acrylonitrile, butadiene, and styrene copolymers. In the case where the first flange or the second flange is joined to a corresponding end of the core, the resin of the core may be the same as or different from the resin of the first flange or the second flange.
The reel for a taping electronic component package includes a separating portion that provides irreversible separation of the flanges. Accordingly, the reel is able to be detached from a taping electronic component package after the taping electronic component package wound around the reel is attached to a tape feeder. Thus, the taping electronic component package is able to be attached to a tape feeder in a small space and, accordingly, an increased number of electronic components are able to be mounted. The “irreversible” relating to the separating portion herein does not mean that the flanges are retained by mechanical assembly after separation and they are able to define and function as a reel or be chemically retained by, for example, fixing with adhesive.
The taping electronic component package detached from the reel for a taping electronic component package is preferably attached to a tape feeder with its wound state being retained, for example. This state may be provided by any method.
The following preferred embodiments of the present invention are examples, and features of different preferred embodiments can be partially exchanged or combined with each other. In the second preferred embodiment of the present invention and subsequent preferred embodiments of the present invention, a description of features common to the first preferred embodiment is omitted, and only different points are described. In particular, similar advantageous effects by similar features are not described in each preferred embodiment.
In a first preferred embodiment of the present invention, the separating portion of the reel for a taping electronic component package is located inside the core and disassembling the core in the axial direction or substantially in the axial direction provides separation of the flanges.
