Description

The present disclosure relates to RF tag components and methods of manufacturing RF tag components.

2. Description of the Related Art In the vicinity of construction sites such as building construction, civil engineering work, plumbing construction, etc., generally, material storage areas for temporarily storing various materials used in construction are provided. A stockyard is usually divided into multiple areas. Various materials are classified in each area according to the construction process, the type of material, and the like.

In recent years, it is known to attach RF tags to these materials and read the information on the RF tags with a reader to efficiently manage materials such as carry-in/out, sorting and storage. Since material storage sites are usually installed outdoors, there is a demand for RF tags with a waterproof function. If the RF tag gets wet with water, the RF tag may be damaged due to poor insulation, corrosion, etc., or the water may absorb or reflect radio waves, making it difficult to communicate between the RF tag and the reader. is.

By the way, it is conceivable to store the RF tag in a bag with a zipper to make the RF tag waterproof. However, it is difficult to completely waterproof a zipper bag, and water that has entered the inside of the bag may adhere to the RF tag. Moreover, once the water has entered the inside of the bag, it is difficult to drain it out of the bag, which accelerates the deterioration of the performance of the RF tag.

Therefore, Patent Document 1 discloses the manufacture of a composite RF tag, which includes loading an RF tag into a mold, injecting resin into the mold, and coating and curing the RF tag with the molten resin. discloses a method. That is, the composite RF tag is formed by integrating the RF tag and resin. Since the RF tag is completely covered with the resin in this manner, water is prevented from adhering to the RF tag.

JP 2010-259068 A

However, in the case of the composite RF tag described in Patent Document 1, although the waterproof function is exhibited, it is difficult to remove the RF tag from the inside of the solidified resin and reuse it. Therefore, there is a concern that a new composite RF tag must be manufactured every time the construction site is changed, which increases the manufacturing cost.

Therefore, the present disclosure describes an RF tag component that is excellent in waterproof property and that enables easy collection of the RF tag, and a method for manufacturing the RF tag component.

In this case, even if the RF tag is not read by the RF tag reader, the operator can confirm at least part of the information recorded in the RF tag by visually checking the corresponding information displayed on the display unit. becomes possible. Therefore, when a large number of materials with RF tag parts exist in the material storage area, the approximate location of the target material is confirmed by the reader, and then the materials existing near the location are tagged. By visually confirming the RF tag components one by one by the operator, it becomes possible to efficiently find the target materials.

Example 3. In the RF tag component of Example 2, the display section is provided on the outer surface of the storage member, and the waterproof film may have optical transparency that allows the display section on the outer surface to be visually recognized. In this case, the display part is also covered and protected with the waterproof film together with the RF tag. Therefore, it is possible to prevent the correspondence information displayed on the display unit from being damaged.

Example 4. In the RF tag component of Example 2 or Example 3, the storage member may include a front side outer surface and a back side outer surface, and the front side outer surface and the back side outer surface may each be provided with a display portion. In this case, the same corresponding information is displayed on both sides (front and back) of the RF tag component. Therefore, when the operator visually confirms the correspondence information, the trouble of turning over the RF tag component is eliminated. Therefore, it is possible to improve the efficiency of the confirmation work of the correspondence information by the operator.

Example 5. In the RF tag component of any one of Examples 1 to 4, the storage member has a sheet shape, and the RF tag may be sandwiched between at least two folded storage members. In this case, the RF tag can be stored very easily in the storage member.
