Substrate Work Machine Position Data Using Arrangement Rules

Solution Overview

Problem

The file size of the control program used by substrate work machines increases with the number of work positions, leading to increased processing time and potential efficiency losses.

Innovation Solution

A work assistance device generates work data using a reference position and arrangement rule to efficiently designate multiple work positions, reducing the file size and processing time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If all work positions are individually designated in the control program, then the number of work positions can be accurately specified, but the file size increases and processing time increases

Engineering Contradiction:

Improvework position designation accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple individual work position designations into a single rule-based definition. Instead of listing each work position separately, the system combines them under a common arrangement rule that defines the reference position, interval, and number of positions, thereby reducing file size and processing time while maintaining accurate designation of all work positions

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the work positions into a structured format with a reference position and systematic intervals. By dividing the work positions into a base position and systematically generated positions based on rules, the system reduces the data representation from individual entries to a compact rule set that can be efficiently processed

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If all work positions are individually designated in the control program, then the number of work positions can be accurately specified, but the file size increases

Engineering Contradiction:

By dividing the work positions into a base position and systematically generated positions based on rules, the system reduces the data representation from individual entries to a compact rule set that can be efficiently processed

Inventive Principle:

3Adaptability or versatility

If a large number of work positions are designated, then comprehensive coverage is achieved, but communication time increases

Engineering Contradiction:

Improvework position coverageVSAvoidcommunication time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent merges multiple individual work position designations into a single rule-based definition. Instead of listing each work position separately, the system combines them under a common arrangement rule that defines the reference position, interval, and number of positions, thereby reducing file size and processing time while maintaining accurate designation of all work positions

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary action by pre-defining the arrangement rules for work positions. The system establishes the reference position, interval, and count of positions in advance, allowing the control program to generate all specific work position coordinates through calculation rather than transmitting each coordinate individually, thus reducing communication time

Inventive Principle:

Principle #10Preliminary action

AI summary

A work assistance device is applied to a substrate work machine for performing predetermined operations on multiple work positions arranged in advance on a substrate. The work assistance device comprises: an acquisition section configured to acquire a reference position and an arrangement rule for multiple work positions, and a data generation section configured to generate work data for designating the multiple work positions using the reference position and the arrangement rule acquired by the acquisition section.
