RFID-Tagged Joining Die for Fast Damage Detection

The patent extracts the inspection function from complex external machinery and integrates it into a simple identification tag attached to the die. The tag contains an antenna and storing element that can be read by a reader device, separating the identification function from the complex fluid medium inspection system while maintaining detection capability.

The patent creates a simplified copy of the inspection function through the identification tag, which stores die condition information that can be read without complex machinery. Instead of using expensive fluid medium inspection equipment, a simple reader device reads the tag to determine die condition, achieving the same inspection goal with minimal complexity.

The die condition information is pre-stored in the identification tag during or before die operation. This allows immediate reading of the die condition without requiring time-consuming fluid medium inspection procedures during the rivet cycle, eliminating delays while maintaining detection accuracy.

The patent replaces the mechanical fluid medium inspection system with an electronic/electromagnetic reading system. The reader device reads the identification tag using electromagnetic fields rather than mechanical fluid pressure systems, enabling faster inspection that does not interrupt the rivet cycle time while maintaining measurement precision.

The identification tag provides real-time feedback on die condition (such as die number, service life, or damage status) that can be read during or between operations. This allows immediate detection of die faults without waiting for periodic inspection intervals, maintaining reliability by catching issues early while avoiding unnecessary die replacements that would reduce productivity.

The die essentially inspects itself through the identification tag that automatically provides condition information. The reader device simply reads the pre-stored information in the tag, eliminating the need for external inspection machinery or manual inspection processes that would reduce productivity while maintaining reliability through continuous monitoring capability.
