Abstract

PROBLEM TO BE SOLVED: To provide a spool case in which a bonding wire wound around a contained spool has no possibility of touching the open edge of a cover at the time of opening/closing the spool case. SOLUTION: A guide bump 13 provided on a cover 4 guides a spool in the central direction of the cover 4 so that a bonding wire wound around the spool does not touch the open edge 4a of the cover. The bonding wire wound around the spool can be prevented from touching the open edge of a cover at the time of opening/closing the spool case by guiding the spool case held in the container body by means of the guide bump.

スが開示されている。2. Description of the Related Art Hitherto, various types of cases have been known as cases for accommodating a spool around which a bonding wire used for assembling a semiconductor device is wound.
For example, Japanese Utility Model Publication No. 58-41188 discloses a container body integrally provided with an upwardly bulging fitting ridge for fitting a spool, and a lid body fitted to an outer peripheral ridge of the container body. A spool case in which a holding portion that fits with a spool is formed in a body in correspondence with the fitting ridge, and the accommodated spool is fixedly held by the fitting ridge and a lid to prevent rattling. Is disclosed.

あった。By the way, an expensive bonding wire such as a gold wire is wound around a spool housed in a spool case of this type, but the spool is fitted in a fitting ridge and held in a container body. When opening or closing the spool case by fitting or removing the lid, there is a possibility that the wire may be damaged due to the opening edge of the lid touching the wire surface.

となるよう形成することが好ましい。In order to achieve the above object, the present invention provides a cover provided with a bulging guide ridge which is inserted into the inside of a body of a spool, wherein the guide ridge is provided with a spool case. The gist is that the spool is guided to open and close. As a specific configuration of the guide ridge, the length of the guide ridge is not less than の of the horizontal length (L) of the cover and within a range protruding from the opening edge of the cover by （(L). It is preferable to form them.

とのないよう、スプールを蓋体中心方向へ導く。In such a configuration, when the spool case is opened and closed while holding the spool in the container body, the guide ridge provided on the lid serves as a guide, and the bonding wire wound around the spool is used as the lid. The spool is guided toward the center of the lid so as not to touch the opening edge of the body.

がたつきを防止し、より確実に保持することが出来る。The holding means provided on the container body can be formed by providing a bulging fitting ridge for fitting the spool to the container body. In this case, the fitting ridge is fitted on one side of the inner periphery of the body of the spool, and the guide ridge is inserted on the other side, so that the spool is held by the fitting ridge and the guide ridge in the spool case, The rattling of the spool in the case can be prevented, and the spool can be held more reliably.

ルを装着する事が出来る。Further, the holding means can be formed by providing an engaging means for detachably engaging the outer peripheral edge of the flange of the spool on the container body. In this case, the holding of the spool by the engagement means does not cause interference with the inside of the spool body, so the spool is held in the container body,
The spool can be mounted on the spool holder of the bonding apparatus regardless of the length of the spool holder and the presence or absence of the spool hooking means.

ことが出来る。The guide ridge is formed in a substantially frusto-conical shape whose outer diameter gradually decreases from the base end toward the tip end, and the base end of the guide ridge is fitted to the inner periphery of the body of the spool. It is preferable to form the outer diameter. In this case, the fitting ridge is fitted on one side of the inner periphery of the body of the spool, and the base end of the guide ridge is fitted on the other side, so that the spool is fitted with the fitting ridge and the guide ridge in the spool case. The spool is held together, and the rattling of the spool in the spool case can be more reliably prevented.

In this example, two engaging portions 7 on the left and right sides are provided so as to correspond to two places on the left and right sides of the outer peripheral edge of the flange 2b, and the engaging portion 7 ′ having no substantially claw-like or substantially hook-like portion is formed by The flange 2b is provided so as to be able to be supported by contacting the lower end side of the outer peripheral edge thereof, and the flange 2b is detachably held by these three engaging portions. The present invention is not limited to this, and an appropriate number capable of holding the spool 2 in a cantilever shape and detachably attaching the spool 2 can be provided at an appropriate position.

を防止し得、洗浄し易いため好ましい。On the inner side surface 5a of the outer peripheral ridge 5, an escape recess 9 corresponding to a protrusion of the spool holder (for example, a spool hooking means made of a spring material) is provided so as not to hinder the formation of the engaging portion 7. In addition, it is provided at a plurality of locations as appropriate as long as the strength, durability, and elasticity required for the container body 3 are maintained. Accordingly, when the spool 2 held by the container body 3 is mounted on the spool holder, the protrusion is released into the concave portion 9 so that the handling becomes easy and the versatility is improved, which is preferable. Also, the recess 9 can be formed wider than shown in the figure. In other words, the wider the recess is, the easier the positioning of the protrusion is, the easier the mounting of the spool 2 to the spool holder is, and the more versatility is further improved. The concave portion 9 is preferably a simple shape because it can prevent the attachment of dust and is easy to clean.

形を防止できる。The grip 6 functions as a handle when the container body 3 is handled, and prevents careless deformation of the engaging portion 7. That is, when the grip portion 6 is not provided, the outer peripheral ridge 5 functions as a grip portion. In this case, the engaging portion 7 is deformed as the outer peripheral ridge 5 is inadvertently deformed, and the spool 2 falls off. It cannot be said that there is no danger of doing so. Therefore, by providing the gripping portion 6 as in this example, when the container body 3 is handled, if the gripping portion 6 is used as a handle, careless deformation of the engaging portion 7 can be prevented.
