Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In component mounting apparatuses, worker errors during the insertion of subsequent tapes into tape feeders can lead to erroneous settings, as the system cannot verify whether the subsequent tape is correctly inserted into the intended feeder, resulting in potential malfunctions.

Innovation Solution

A component verification method and system that includes a component ID reading process, tape insertion detection, feeder specification, and verification of the correspondence between the read ID and the specified feeder to prevent erroneous settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If component verification is performed using manual ID reading and notification lamp guidance, then component identification accuracy is improved, but worker operation errors increase due to inability to verify correct insertion

Engineering Contradiction:

Improvecomponent identification accuracyVSAvoidinsertion correctness

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system implements automatic feedback by detecting which tape feeder actually received the subsequent tape and comparing it with the intended feeder. The notification lamp provides visual feedback to guide workers, while the detection system provides automated verification feedback to confirm correct insertion, eliminating the gap between identification accuracy and insertion reliability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The tape insertion detection system enables the apparatus to self-verify insertion correctness automatically. By using detection means to identify which feeder received the tape and automatically comparing it with the intended destination, the system performs self-validation without requiring additional manual verification steps from workers.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If splicingless tape feeder is used to reduce worker workload, then ease of operation is improved, but error detection capability deteriorates due to lack of physical connection verification

Engineering Contradiction:

Improvetape replenishment simplicityVSAvoidinsertion correctness verification

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The notification lamp serves as an intermediary between the control system and the worker, providing visual guidance to the correct feeder. The tape insertion detection system acts as an intermediary that automatically monitors and verifies which feeder actually received the subsequent tape, bridging the gap between simple operation and reliable verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual verification methods with automated detection means. Instead of relying on workers to physically verify tape insertion through mechanical connection checks, the system uses detection sensors and automated comparison logic to verify insertion correctness, maintaining simplicity while improving reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A component verification method includes a component ID reading process of reading a component ID corresponding to a stored component of a subsequent tape, a tape insertion detecting process of detecting that the subsequent tape has been inserted into a tape feeder, a feeder specifying process of specifying a tape feeder in which the insertion of the subsequent tape has been detected, and a component verifying process of verifying whether or not a correspondence relationship between the read component ID and the specified tape feeder is correct.
