Solution Overview

Problem

Existing component supply devices struggle to smoothly collect carrier tapes with large curls, as they often get caught in the tape discharge passage, preventing efficient collection.

Innovation Solution

Incorporating a curl corrector mechanism within the component supply device that guides and corrects the curl of empty tapes, ensuring they are directed smoothly into the discharge chute for collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a carrier tape with large curl is discharged from the tape feeder, then the component supply device can continue operation, but the empty tape gets caught in the tape discharge passage and cannot be smoothly collected

Engineering Contradiction:

Improvecomponent supply continuityVSAvoidempty tape discharge smoothness

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

A guide member is introduced as an intermediary element between the tape discharge passage and the collection box. This guide member has a curved surface that matches the curl of the empty carrier tape, acting as a mediator to gradually redirect the curled tape into the collection box without causing it to get caught or jam in the discharge passage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If the carrier tape is wound tightly on the reel, then storage efficiency is improved, but the empty tape develops large curl that prevents smooth collection

Engineering Contradiction:

Improvetape storage densityVSAvoidempty tape curvature

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The guide member is designed with a curved surface that corresponds to the natural curl shape of the empty carrier tape resulting from tight winding. This curvature allows the guide member to accommodate and gradually straighten the curled tape as it enters the collection box, preventing jamming while maintaining efficient storage density.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Device complexity

If no curl correction mechanism is provided, then device complexity is reduced, but empty tapes with large curl cannot be smoothly collected

Engineering Contradiction:

Improvetape discharge mechanism simplicityVSAvoidtape collection reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The curl correction function is extracted as a separate, dedicated guide member rather than being integrated into the main tape feed mechanism. This separate guide member specifically addresses the curl issue without complicating the primary component supply function, maintaining overall system simplicity while improving collection reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A component supply device that supplies a component stored in a carrier tape to a component mounting apparatus, the component supply device includes a curl corrector that corrects curl of an empty tape which is a carrier tape from which the component is picked up by the component mounting apparatus.
