Component Mounter Feeder ID Verification for Accurate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting systems face challenges in accurately determining whether to use supply position shifting data during model switching, leading to potential mounting faults due to incorrect application of data when tape feeders are changed.
Innovation Solution
A component mounting system that includes an external set-up device with imaging and calculation capabilities to create and update supply position shifting data, linking it to feeder addresses and IDs, and a comparator within the component mounter to verify the accuracy of this data upon carriage attachment, ensuring correct suction nozzle positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If supply position shifting data is created in advance using an external set-up device, then model switching time is reduced and productivity is improved, but there is a risk that incorrect data may be applied when tape feeders are changed, leading to mounting faults
Solution Approach 1:
The system compares the feeder ID read from the carriage with the feeder ID stored in the supply position shifting data. This feedback mechanism ensures that the correct data is applied to the correct feeder, preventing mounting faults while maintaining fast model switching.
Solution Approach 2:
The supply position shifting data is created in advance using an external set-up device before production begins. This preliminary action allows the data to be ready for immediate use during model switching, reducing setup time while the subsequent ID comparison ensures correct application.
2Manufacturing precision
If the suction nozzle teaching work is performed for each tape feeder individually, then accurate component supply is ensured, but a fixed amount of time is required which reduces productivity
Solution Approach 1:
Instead of performing teaching work for each feeder individually, the system creates supply position shifting data that copies the position information for multiple feeders in advance. This data can then be applied to multiple feeders simultaneously, maintaining accuracy while reducing the time required.
Solution Approach 2:
The supply position shifting data serves as a universal solution that can be applied to multiple tape feeders with the same feeder ID. This multi-functionality allows one set of data to correct positions for many feeders, eliminating the need for individual teaching work for each feeder.

AI summary
An external set-up device calculates a shift amount of a supply position of a component which is supplied by a tape feeder that is disposed on the carriage. The storage stores supply position shifting data in which the shift amount of the component supply position is related to a feeder address and a feeder ID. The component mounter compares the feeder ID of the tape feeder with the feeder ID included in the component supply position shifting data which is read from the storage, and, in a case in which the feeder IDs do not match, calculates the shift amount of the component supply position of the corresponding tape feeder and updates the supply position shifting data. The component mounter mounts the components onto a board based on the updated component supply position shifting data.
