Solution Overview

Problem

When using a feeder that can automatically convey carrier tape to a pickup position, there are challenges in performing component verification and ensuring correct loading without removing the feeder from the component supply device.

Innovation Solution

A component supply device with a control device that guides the insertion of carrier tape to the correct slot position, checks for correct insertion using a recognition signal, and sends a supply command to the feeder, allowing for automated component verification and loading without removing the feeder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the feeder remains fixed in the slot of the component supply device for automatic carrier tape conveyance, then automated component supply is achieved, but component verification becomes difficult and loading mistakes increase

Engineering Contradiction:

Improveautomated component supplyVSAvoidcomponent verification accuracy

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The system performs preliminary component verification by reading the barcode on the reel before the carrier tape is loaded onto the feeder. The control device stores the component information and compares it with the feeder slot assignment in advance, ensuring verification is completed before the feeding process begins, thus maintaining both automation and reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control device provides feedback by comparing the barcode information read from the reel with the expected component information for the target feeder slot. This feedback mechanism verifies whether the correct carrier tape is loaded onto the correct feeder, preventing loading mistakes while maintaining automated operation

Inventive Principle:

Principle #23Feedback

2Extent of automation

If the feeder remains fixed in the slot of the component supply device, then automated component conveyance is enabled, but component verification work becomes complex

Engineering Contradiction:

Improveautomatic carrier tape conveyanceVSAvoidcomponent verification process

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The system enables self-service verification by automatically reading the barcode on the reel, storing the component information in the control device, and comparing it with the feeder slot assignment. This automated self-verification process eliminates the need for manual verification work while maintaining simple operation procedures

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical verification process is replaced by an automated optical and electronic system. A barcode reader optically reads the barcode on the reel, the control device electronically stores and compares the information, substituting manual verification with automated detection and control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If barcode reading of the feeder is required for component verification, then component identification is possible, but the process becomes difficult and time-consuming

Engineering Contradiction:

Improvecomponent identification accuracyVSAvoidverification time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary barcode reading of the reel before carrier tape loading. The control device reads and stores the component information in advance, so that when the carrier tape is loaded onto the feeder, the verification is already completed or can be quickly confirmed, eliminating the need for time-consuming verification during the feeding process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the component information by reading the barcode on the reel and storing it in the control device's memory. This information copy is then used for verification against the feeder slot assignment, eliminating the need to physically handle or re-read barcodes during the loading process

Inventive Principle:

Principle #26Copying
