Abstract:
1. A method for manufacturing a long-range radio frequency identification metallic product, comprising the steps of: a metallic first antenna preparation, an electronic tag module patch preparation, an electronic tag mounting process, an electronic tag sealing process and an identity surface treatment process; in the metallic first antenna preparation a metallic first antenna being manufactured by a metallic first antenna body manufacturing process, a resonance chamber molding manufacturing process and a resonance chamber surface treating process; in the metallic first antenna body manufacturing process a metallic first antenna body of a predetermined shape being formed by punching on a metallic plate selected from a metallic product; in the resonance chamber molding manufacturing process two long inner slots and an outer slot being formed on one sidewall of the metallic first antenna body by punching, a geometry concave slot being formed on an intersection of the inner slots and the outer slot and having a height difference with respect to a hole-outer surface by punching or forging or machining of computer numerical control milling machine, and a rectangular recessed portion molded as a resonance chamber being formed on the intersection of the inner slots and the outer slot within the concave slot, wherein an inner surface of the concave slot located outside the rectangular recessed portion is served as a metallic ground surface for the resonance chamber; in the resonance chamber surface treating process a surface of the resonance chamber surface being treated by a ceramic processing so that an anti-interference ceramic thin film is formed on the surface of the resonance chamber; in the electronic tag module patch preparation an electronic tag module patch being formed by a substrate integrated process, an antenna allocation chip bonding process and a module packaging process, wherein in the substrate integrated process a first rigid clip made of an insulating low dielectric coefficient material and provided with a breaking cutline is bonded to a rigid thin-plate substrate made of a low dielectric coefficient material, in the antenna allocation chip bonding process a loop copper foil second antenna or inductance formed by etching and a radio frequency identification chip are attachingly bonded on the first rigid clip, and a plurality of conductive metallic wires made of gold, aluminum and copper are electrically connected between the copper foil second antenna and the radio frequency identification chip on the first rigid clip by wire bonding, and in the module packaging process a second rigid clip which is made of an insulating low dielectric coefficient material and provided with a breaking cutline corresponding to the breaking cutline of the first rigid clip is overlapped on a bottom surface of the first rigid clip so that the copper foil second antenna and the radio frequency identification chip are packaged between the first rigid clip and the second rigid clip, and a bottom surface of the second rigid clip is served as a mounting surface when the electronic tag module patch and the metallic first antenna are jointed; in the electronic tag mounting process a mounting surface of the electronic tag module patch being bonded to the resonance chamber of the metallic first antenna and jointed to the metallic ground surface within the concave slot so that the loop copper foil second antenna or inductance is matched to the metallic first antenna at the rectangular recessed portion to generate resonance and induction; in the electronic tag sealing process a colloidal filling glue, which is filled in the resonance chamber of the metallic first antenna, the outer slot of the metallic first antenna body and the concave slot attached with the electronic tag module patch by glue dripping or glue filling, is treated by baking and cooling processes in a stove so that the electronic tag module patch is sealed and bound in the metallic first antenna by the cured filling glue and the metallic first antenna is provided with a grinded and embellish glued surface; and in the identity surface treatment process the metallic first antenna treated in the electronic tag sealing process being coated or sprayed on a surface thereof with an anti-interference ceramic paint and treated by baking and cooling processes in the stove so that an anti-interference surface layer is formed on the surface of the metallic first antenna.
