Description

IC tag mounting structure

The present invention relates to a mounting structure of an IC tag mounted on a tool holder.

IC tags are used as identification media for objects. For example, an IC tag is attached to a tool holder used in a work machine or the like to identify the tool holder. The IC tag mounted on the tool holder is composed of an IC chip with a memory inside and a coil serving as an antenna, and is integrally molded by using a synthetic resin.

This IC tag receives data from an external writing device and stores data related to the tool holder in an IC chip, and reads the stored data by bringing an external reading device closer. In this way, the management of the tool holder can be performed accurately and easily.

The IC tag is mounted in a state where it is buried in a required part of the tool holder. The technology described in Patent Document 1 is to hold an IC tag (tool ID) in a recessed portion of a mounting tool, and to form a tool holding An IC tag is mounted on the tool holder by fixing the mounting tool with a screw hole. Further, in the technology described in Patent Document 2, a step portion is formed on an outer peripheral surface of an IC tag (data identification chip), and a snap ring is disposed between the step portion and a hole portion formed in a tool holder. Thereby, an IC tag is mounted on the tool holder. In addition, it is also conceivable to mount the IC tag with an adhesive on the hole portion formed in the tool holder.

[Patent Document 2] Japanese Patent Laid-Open No. 2000-343344

According to the technology described in Patent Document 1, when the thickness of the IC tag is thin, screw holes cannot be provided on the outer surface of the tool holder, and the IC tag cannot be mounted on the tool holder. In addition, the IC tag mounting tool is configured in such a manner that a recess for holding the IC tag and a mounting part for screw fixing are arranged side by side. Therefore, the IC tag mounting area in the tool holder becomes large.

According to the technology described in Patent Document 2, the external shape of the IC tag must be processed. For example, a circular IC tag having a general shape cannot be mounted on a tool holder. When an IC tag is mounted on a tool holder using an adhesive, a disc-shaped IC tag can be used. However, once the IC tag is attached using an adhesive, it is difficult to remove it from the tool holder and reuse it. In addition, the safety of IC tags using adhesives Problems with the mounting method include: centrifugal force during use of the tool holder may cause the IC tag to fall off from the tool holder, and it will take time to allow the adhesive effect to be fully exerted. As such, there is still room for improvement in mounting IC tags on tool holders.

Therefore, it is desirable to provide an IC tag mounting structure that can easily and stably mount an IC tag to a tool holder.

A feature of the IC tag mounting structure of the present invention is that it includes a recessed portion provided on the outer surface of the tool holder, a disc-shaped IC tag, and an IC tag holding portion formed in a ring shape. The state in which the IC tag holding portion is nested is disposed in the recessed portion, and the IC tag is held in the recessed portion by elastically deforming the IC tag holding portion.

According to this structure, a disc-shaped IC tag is arrange | positioned in the recessed part of a tool holder in the state nested in the IC tag holding part. Therefore, by forming the IC tag holding portion that matches the shape of the IC tag, the IC tag can be mounted on the tool holder without processing the outer shape. In addition, the IC tag is held in the recess of the tool holder by elastically deforming the IC tag holding portion, so that the IC tag can be stably held on the tool holder.

The IC tag holding portion may include an abutting portion that abuts a part of an end face of the IC tag at an end portion on an opening side of the recessed portion, and includes an elastic structure for holding the IC tag in the recessed portion. Pieces.

The IC tag embedded in the IC tag holding portion is mounted in a state where the end surface is exposed from the outer surface of the tool holder. When the tool holder rotates, it receives centrifugal force. Therefore, when the fitting force of the IC tag to the IC tag holding portion is weak, the IC tag may be detached from the IC tag holding portion. Therefore, according to this structure, the end portion of the IC tag holding portion at the opening side of the recessed portion has a contact portion that abuts a part of the end surface of the IC tag. Thus, the movement of the IC tag embedded in the IC tag holding portion is restricted by the abutting portion. As a result, the IC tag can be reliably prevented from being separated from the IC tag holding portion, and the IC tag can be stably held in the tool holder. In addition, since the IC tag is held by an elastic member included in the IC tag holding portion, the IC tag can be easily mounted on the tool holder.

The IC tag holding portion may have an abutting portion that abuts a part of an end face of the IC tag at an end portion on the opening side of the recessed portion, and has an engaging portion configured to be elastically deformable to engage the recessed portion.

According to this structure, the end portion of the IC tag holding portion on the opening side of the recess has a contact portion that abuts a part of the end surface of the IC tag. In this way, since the movement of the IC tag embedded in the IC tag holding portion is restricted by the abutting portion, the IC tag can be stably held in the tool holder. In addition, since the IC tag holding portion has an elastically deformable engaging portion, the IC tag can be easily mounted on the tool holder, and the number of parts for mounting the IC tag on the tool holder can be reduced.
