Electronic Component Mounting Machine Interference Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic component mounting machines, there is a risk of interference between the nozzle or clamp member and adjacent supply devices or components during the collection and mounting of electronic components, particularly with large components, as existing technologies lack effective methods to check for and prevent such interference.
Innovation Solution
An operation checking device that includes memory sections for storing operation programs and shape data, acquiring sections for information and shape data, a processing section for simulation, and a display section to visualize component and tool coordinates in three dimensions, allowing for the simulation and correction of operation paths to prevent interference.

Engineering Contradiction Analysis
1Productivity
If a clamp member is used to collect large electronic components, then the collection capability is improved, but the risk of interference with adjacent supply devices or components increases
Solution Approach 1:
The system performs preliminary action by checking the operation program in advance to detect potential interference between the clamp member and adjacent supply devices or components before actual collection occurs. The checking device simulates the collection process and identifies interference risks, allowing operators to correct the operation program before execution, thus preventing harmful interference while maintaining efficient collection capability.
2Productivity
If the pickup position is entered incorrectly in the operation program, then programming efficiency is maintained, but interference with adjacent supply devices or components occurs
Solution Approach 1:
The checking device implements feedback by automatically checking the operation program for potential interference issues. When interference is detected, the system provides feedback to the operator through display, allowing correction of the operation program. This feedback mechanism maintains programming efficiency by automating the detection process while preventing interference errors that would otherwise require manual detection and correction.
3Device complexity
If conventional technology is used without interference checking, then device complexity is reduced, but interference detection capability is lost
Solution Approach 1:
The checking device uses copying by creating a virtual model of the collection process through operation simulation. It acquires shape data of the clamp member and electronic components, and simulates the collection operation to detect interference. This copying approach enables interference detection capability without significantly increasing physical device complexity, as the checking is performed through software-based simulation rather than additional physical sensors or mechanisms.
