Solution Overview

Problem

Conventional component mounting apparatuses face challenges in maintaining traceability of roll bodies due to their movement between cassettes, leading to unknown or lost track of roll body locations.

Innovation Solution

The apparatus includes a first and second cassette with RFID tags, where the cassettes are arranged with their openings facing each other, and a wireless communicator updates the RFID tag information when the carrier tape is switched, ensuring traceability by linking the information update with the start of carrier tape conveyance from the second cassette to the first.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the roll body is moved between cassettes for component supply, then the component supply continuity is improved, but the traceability of the roll body deteriorates

Engineering Contradiction:
Improvecomponent supply continuityVSAvoidroll body traceability
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system implements feedback by continuously updating the RFID tag information with roll body identification data whenever the carrier tape is conveyed from one cassette to another. The information updater receives conveyance start signals and updates the RFID tag accordingly, ensuring that the latest roll body information is always recorded and traceable, thus resolving the traceability issue while maintaining supply continuity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The RFID tag serves as an intermediary carrier that stores and transmits roll body identification information. Instead of directly tracking the physical roll body movement, the system uses the RFID tag as an intermediate information storage medium that can be updated and read remotely, enabling traceability without interfering with the physical component supply process

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the carrier tape is automatically conveyed from one cassette to another, then the operation efficiency is improved, but the complexity of the tracking system deteriorates

Engineering Contradiction:
Improveautomatic tape switchingVSAvoidtracking system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically updating the RFID tag information without requiring manual intervention. The information updater automatically detects when carrier tape conveyance starts and updates the RFID tag with the appropriate roll body information, making the tracking system simple to operate while maintaining automatic efficiency

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical tracking systems with an electronic information update mechanism. Instead of using mechanical sensors or visual inspection systems to track roll bodies, the system uses RFID tags and wireless communicators to electronically store and retrieve identification information, significantly reducing system complexity while maintaining automatic operation capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A component mounting apparatus includes a first cassette, a second cassette, a cassette attachment part, a first wireless communicator, and an information updater. The first cassette and the second cassette are cassettes each having a space that accommodates a roll body of a carrier tape, an opening that allows the roll body to be loaded into and unloaded from the space, and an RFID tag. The first and second cassettes are attached to the cassette attachment part such that they are arranged, with their respective openings facing each other. The first wireless communicator communicates with an RFID tag of the first cassette attached to the cassette attachment part. The information updater updates, through the first wireless communicator, information stored in the RFID tag of the first cassette, in linkage with start of conveyance of the carrier tape from the second cassette by the component supply unit.
