Component Mounting Offset Analysis for Suction Nozzle Deterioration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting systems face challenges in accurately identifying and addressing position offsets in the component suction position due to aged deterioration of suction nozzles, leading to defects in the component loading process.
Innovation Solution
A component mounting system equipped with a management device that acquires and analyzes suction position offset data, along with parameter information and processing state images, to identify the generating factors for position offsets, allowing for appropriate corrective measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional calibration based on component position recognition is used, then manufacturing precision of component loading position is improved, but the ability to identify generating factors for suction position offset deteriorates
Solution Approach 1:
The management device collects suction position offset data from the mounting apparatus and provides feedback through distribution display, enabling identification of generating factors such as suction nozzle deterioration. This feedback mechanism allows operators to take corrective actions based on the identified causes, resolving the contradiction by maintaining precision while enabling root cause analysis.
Solution Approach 2:
The management device acts as an intermediary between the mounting apparatus and the operator. It collects raw suction position offset data, processes it into distribution information, and presents it in a comprehensible format. This intermediary function enables the operator to identify generating factors without directly accessing complex raw data, thus preserving information while maintaining precision.
2Productivity
If suction nozzle is used without monitoring, then productivity is maintained, but manufacturing precision deteriorates due to position offset
Solution Approach 1:
The management device continuously collects suction position offset data and displays distribution information, providing real-time feedback on suction nozzle performance. This allows operators to monitor precision degradation while maintaining productivity, and to take corrective actions only when necessary, thus resolving the contradiction between continuous operation and quality maintenance.
Solution Approach 2:
The system performs preliminary monitoring of suction position offset before defects occur. By displaying distribution information and identifying trends in suction nozzle performance, the system enables preventive maintenance actions before position offset exceeds acceptable limits, maintaining both productivity and precision.
Data Source
AI summary
In a management device, a management storage unit stores management data in which suction position offset data, parameter information, and a processing state image are associated with each other, the management data being acquired from a mounting apparatus by a management communication unit. When a command to select one piece of parameter information from the various pieces of parameter information is input, a management control unit causes a management display unit to display a suction position offset distribution indicating distribution of a data group of the suction position offset data. Once this has occurred, when a command to select one or more specific position offset data from the data group of the suction position offset distribution is input, the management control unit causes the management display unit to display the processing state image corresponding to the specific position offset data simultaneously with the suction position offset distribution.
