Solution Overview

Problem

Existing wire bonding machines require manual spool exchange when the wire on one spool is depleted, leading to decreased efficiency in the wire bonding process.

Innovation Solution

A wire supply module with a joint machine that joins the ends of wires from multiple spools, allowing continuous wire supply without the need for manual spool exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual spool exchange is used when wire is depleted, then spool replacement can be completed, but wire bonding efficiency decreases due to interruption

Engineering Contradiction:

Improvewire bonding efficiencyVSAvoidtime lost during spool exchange

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The joint machine enables continuous wire supply by automatically joining the end of one spool's wire to the beginning of the next spool's wire, eliminating interruptions during spool transitions and maintaining continuous wire bonding operation

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-service by automatically detecting when wire is depleted and executing the spool transition and wire joining process without requiring manual intervention, allowing the wire bonding machine to service itself during spool changes

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual spool exchange is performed, then spool replacement is achieved, but operation complexity increases due to manual intervention requirements

Engineering Contradiction:

Improveease of spool replacementVSAvoidcomplexity of spool exchange process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The joint machine automates the entire spool exchange process including wire alignment, joining, and cutting operations, making the system self-sufficient and eliminating the need for operator intervention during spool transitions

Inventive Principle:

Principle #25Self-service

3Reliability

If multiple spools are connected manually, then wire continuity can be achieved, but precision decreases due to manual alignment errors

Engineering Contradiction:

Improvewire connection reliabilityVSAvoidwire alignment precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The joint machine replaces manual mechanical alignment with an automated mechanical system that precisely positions and joins wire ends from multiple spools, ensuring consistent alignment precision through controlled mechanical mechanisms rather than manual operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The joint machine acts as an intermediary device between multiple spools, providing a controlled environment and mechanism for precise wire alignment and joining that eliminates the precision limitations of direct manual connection

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A wire supply module may include a plurality of spools and a joint machine. Wires may be wound on the spools. The joint machine may be arranged between the spools to join the wires to each other. The joint machine may include a housing, a jointer and a cutter. The housing may have a joint passage configured to receive ends of the wires. The jointer may be arranged in the housing to join the ends of the wires to each other. The cutter may be arranged in the housing to partially cut the joined ends of the wires. Thus, when all the wire on a currently used spool may be exhausted, the wire on another spool may be joined to the wire on the currently used spool so that the wire may be continuously supplied without a spool exchange.
