Shared Measurement Device Switching for Mounting Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic component mounting systems require multiple measurement devices, leading to increased installation costs due to lower usage frequency, as they need to be installed in each machine despite infrequent use.
Innovation Solution
A mounting system with multiple machines sharing a single measurement device, connected via a switching device controlled by a central unit, which switches the measurement device between machines based on request, and includes a storage device for correction values to ensure accurate measurements across varying measurement paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a measurement device is installed in each electronic component mounting machine, then measurement reliability is improved, but installation cost increases
Solution Approach 1:
The measurement device is designed to serve multiple mounting machines simultaneously through the switching device, allowing one measurement device to perform measurement functions for several machines rather than requiring dedicated measurement devices for each machine
Solution Approach 2:
A switching device is introduced as an intermediary component that enables the measurement device to connect to and serve multiple mounting machines, acting as a mediator between the single measurement device and multiple machines
2Productivity
If multiple measurement devices are installed, then measurement availability is improved, but device complexity increases
Solution Approach 1:
The switching device enables a single measurement device to serve multiple mounting machines, providing measurement availability for all machines while avoiding the complexity of multiple independent measurement devices
3Productivity
If measurement frequency is reduced, then production efficiency is improved, but measurement precision may deteriorate
Solution Approach 1:
The system performs measurement at predetermined intervals or when components are replaced, conducting measurements in advance at strategic points rather than continuously, ensuring component quality while maintaining production efficiency
Solution Approach 2:
The measurement operation is executed periodically at set intervals or triggered by specific events such as component replacement, providing regular quality checks without requiring continuous measurement that would reduce production efficiency

AI summary
In a mounting system including multiple mounting machines, there is provided a mounting system that is capable of reducing the number of measurement devices that measure electrical characteristics of an electronic component. A control device 13 controls a switching device 12 in order to connect a measurement device 14 and a mounting machine 16 that transmitted request information for measuring the electrical characteristics of the electronic component. When transmitting an instruction for starting measurement to the measurement device 14 and receiving a characteristic measurement value from the measurement device 14, the control device 13 transfers the received characteristic measurement value to the mounting machine 16 that transmitted request information.
