Solution Overview

Problem

The existing electronic component mounting machines do not consider offset values of multiple divided boards, leading to reduced mounting efficiency due to the need for the mounting head to move between each board, thereby decreasing productivity.

Innovation Solution

A control device that groups some divided boards based on the positions of suction nozzles and boards within the printed circuit board, optimizing nozzle and board positions to efficiently mount components, and a data input device for user selection and data input to the control device, allowing for reduced memory usage by storing only reference board data and offset values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the mounting head moves to each divided board individually to mount electronic components, then the mounting position can be accurately controlled, but the mounting efficiency and productivity are reduced due to repeated movements

Engineering Contradiction:

Improvemounting position accuracyVSAvoidmounting efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The control device pre-calculates and stores offset values between divided boards before mounting operations begin. This preliminary preparation allows the system to quickly determine mounting positions across multiple boards without performing repeated measurements or calculations during the mounting process, thereby maintaining positioning accuracy while improving efficiency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system stores mounting position data from a reference divided board and uses offset values to generate mounting position data for other divided boards. This copying approach eliminates the need to store complete mounting position data for each individual board, reducing memory requirements while maintaining accurate positioning through the use of relative offset calculations

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If the mounting head moves between multiple divided boards to mount electronic components, then all boards can be serviced, but the number of movements increases and productivity decreases

Engineering Contradiction:

Improveability to service multiple boardsVSAvoidproductivity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Offset values between divided boards are pre-calculated and stored in the control device before mounting operations begin. This preliminary action enables the system to efficiently service multiple boards by simply adding the appropriate offset to the reference board's mounting position data, eliminating the need for repeated complex calculations and maintaining high productivity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control device uses a universal reference board mounting position data set that can be applied to all divided boards through the addition of respective offset values. This universal approach allows the system to service multiple different boards using a single base data set, enhancing versatility while maintaining efficient operations

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If complete mounting position data is stored for each divided board, then accurate mounting can be achieved, but memory requirements increase

Engineering Contradiction:

Improvemounting position data accuracyVSAvoidmemory capacity

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

Instead of storing complete mounting position data for each divided board, the system stores only the reference board's mounting position data and offset values. The mounting position data for other boards is generated by copying the reference data and adding the appropriate offset, significantly reducing memory requirements while maintaining full positioning accuracy

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system extracts only the essential reference board mounting position data and offset values from the complete set of board-specific data. This extraction approach removes redundant information while preserving all necessary mounting position information through the use of relative offset calculations

Inventive Principle:

Principle #2Taking out (Extraction)
