Solution Overview

Problem

The increasing speed of component mounters generates large volumes of cut carrier and cover tapes in a short time, requiring frequent manual movement of storage members across manufacturing lines, which is time-consuming and inefficient.

Innovation Solution

A component mounter system that includes a waste box for storing cut tapes, a scraping device to remove the tapes when a predetermined amount is reached, and a control device to automate the scraping and collection process, with a collection device that can move between multiple mounters to collect the tapes efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If component mounter operates at high speed, then productivity is improved, but large volumes of cut tape are generated in a short time requiring frequent manual handling

Engineering Contradiction:
Improvemounting speedVSAvoidtime for manual tape handling
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system enables automatic self-service through the control device that monitors waste box fill levels and automatically activates the scraping device to eject tapes when the predetermined amount is reached, eliminating the need for manual intervention and allowing the mounter to continue high-speed operation without interruption

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The waste box provides preliminary storage capacity for accumulated cut tapes before ejection is needed. The scraping device is pre-positioned and ready to activate automatically when the predetermined fill level is reached, ensuring continuous operation without manual intervention

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If operator frequently moves storage members between multiple component mounters, then tape waste can be collected, but the work is very time consuming

Engineering Contradiction:
Improvetape collection operationVSAvoidtime for moving storage members
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

Each component mounter is equipped with its own waste box and scraping device that automatically ejects tapes when full. The collection device with moving mechanism autonomously travels between mounters to collect tapes, completely eliminating the need for operators to manually move storage members between machines

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of moving storage members by operators is replaced by an automated system consisting of the moving mechanism that autonomously transports the collection device between mounters, and the scraping device that automatically ejects tapes using mechanical force

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

3Manufacturing precision

If tape ejection box is inclined toward operation side, then tape waste can be accumulated without unevenness, but the structure becomes more complex

Engineering Contradiction:
Improvetape accumulation uniformityVSAvoidejection box structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The scraping device uses a horizontally moving scraper that moves parallel to the bottom face of the waste box, creating an equipotential scanning path that ensures uniform tape accumulation across the entire box width without requiring the box itself to be inclined

Inventive Principle:
Principle #12Equipotentiality

AI summary

With component mounter 1, even if a large amount of cover tape 33 and carrier tape 34 after cutting is generated in a short time, because the tapes 33 and 34 can be temporarily stored in waste box 6, the processing frequency of the tapes 33 and 34 can be reduced. Further, when the amount of tapes 33 and 34 stored in waste box 6 reaches a predetermined amount, because the tapes 33 and 34 can be automatically scraped out of waste box 6, the processing efficiency of the tapes 33 and 34 can be improved.
