20. A method for manufacturing a rubber product, the rubber product comprising an RFID chip and an antenna, and the RFID chip being electrically connected to a main surface of the antenna;
wherein the rubber product further comprises a pair of release agents each having a slippery surface, and
covering the module with the slippery surfaces of the pair of release agents, either mounting the module covered with the slippery surfaces of the pair of release agents on vulcanized rubber or putting the module covered with the slippery surfaces of the pair of release agents in a hole formed in vulcanized rubber, and vulcanizing unvulcanized rubber to embed the module covered with the slippery surfaces of the pair of release agents in vulcanized rubber.
The above-mentioned Reference 1 describes a method in which a through-hole is formed in a corner at the edge of a mat, that is, a rubber product, a module is inserted in the through-hole, unvulcanized rubber is also inserted in the through-hole to enclose the module, and pressure and heat are applied from both sides of the unvulcanized rubber to vulcanize it, thereby making it a unified part of the vulcanized rubber that makes up the mat.
In addition, the conventional technology, there are possibilities of causing bonding fracture between an RFID chip and an antenna, as well as antenna deformation. Also, there are cases in which, in mounting an electronic device to a rubber product, a module is embedded in vulcanized rubber by vulcanizing unvulcanized rubber, with priority being placed on the appearance or design or a need to satisfy the function requirements of the rubber product. Usually, a process of vulcanizing unvulcanized rubber involves heating the unvulcanized rubber to a temperature of 100° C. to 300° C. and then cooling the heated rubber down to room temperature. The process causes the rubber to largely shrink, because the linear thermal expansion coefficient of rubber is very large. Therefore, the vulcanization process tends to cause a bonding fracture between an RFID chip and an antenna, as well as antenna deformation.
Under the rubber base 2, the base part 4, which has been processed to have an increased surface lubricity and which is larger than an image pf the RF10 inlet produced by projection from above, is disposed such that the inner surface thereof, which is processed to have an increased surface lubricity, closely faces the RFID inlet 9.
The antenna 6 is made of a flexible organic film that is coated with a metallic film. The organic film material may be, for example, a polyimide resin or a polyethylene terephthalate resin. The metallic film material may be, for example, an alloy of copper and tin, or aluminum. The polyimide film sheets 7, each having an adhesive layer, have a base material thickness of 0.01 to 0.1 mm. The thickness of the adhesive layer is adjusted as required depending on the thickness of the RFID chip 5 to be used. The adhesive material is preferably a thermosetting resin, such as a silicone resin, an epoxy resin or a polyimide resin, which may be processed for increased flexibility. Shown on the right in FIG. 5A is an enlarged cross-sectional view, taken along line A-A, of the RFID inlet 11 having a laminated structure.
FIG. 5B shows the RFID inlet 11 inserted in a base part 4 having a cylindrical shape. The inner surface 12 of the base part 4 has been processed to have an increased surface lubricity. Shown on the right in FIG. 5B is an enlarged cross-sectional view taken along line B-B.
Shown on the right in FIG. 5C is an enlarged cross-sectional view taken along line C-C. With the base part 4 flattened, there are gaps (spaces) 13 generated between the main surfaces and side surfaces of the antenna 6 and the inner surface of the base part 4, which is processed to have an increased surface lubricity. The gaps 13 give some freedom of movement to the RFID inlet 11, contributing toward generating a stress relief effect when the RFID inlet is embedded in the rubber sheet. In the present embodiment of the invention, although the base part 4 has a tubular shape with open ends, it goes without saying that the base part 4 may have a sack-like shape with one end closed.
