Tape Feeder Mounting Position Determination for SMD Pick-and-Place
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face inefficiencies in simultaneously holding components from multiple tape feeders by multiple holding tools due to deviations in supply positions, leading to poor production efficiency and potential misalignment of electronic components during mounting.
Innovation Solution
The system determines the mounting positions of multiple tape feeders based on pre-shipment and working position information to ensure that the deviation between their supply positions is within a predetermined range, allowing for simultaneous and accurate holding by multiple suction nozzles.

Engineering Contradiction Analysis
1Productivity
If multiple tape feeders are mounted on feeder mounting sections to supply components to multiple holding tools, then the productivity is improved by simultaneous component holding, but the manufacturing precision deteriorates due to deviations in supply positions of the tape feeders
Solution Approach 1:
The system performs preliminary determination of mounting positions for multiple tape feeders before actual mounting. The control device calculates optimal mounting positions based on pre-acquired position information of the tape feeders, ensuring that when the feeders are mounted and components are supplied, the supply positions will be within the acceptable range for simultaneous holding by multiple suction nozzles.
Solution Approach 2:
The system uses position information of tape feeders (acquired before mounting) as feedback to determine optimal mounting positions. The control device processes this position information and adjusts the mounting position assignments to compensate for inherent variations in feeder positions, ensuring accurate component supply positions despite initial position deviations.
2Device complexity
If tape feeders are mounted at fixed positions, then the device complexity is reduced, but the adaptability deteriorates because position deviations prevent appropriate component holding
Solution Approach 1:
The system introduces dynamic adaptability by allowing mounting positions to be determined based on actual feeder position characteristics rather than being fixed. The control device dynamically assigns mounting positions for multiple tape feeders based on their individual position information, enabling the system to adapt to variations in feeder positions while maintaining simple mounting structures.
Solution Approach 2:
The system changes the parameter of mounting position based on the position information of each tape feeder. Instead of using a single fixed mounting position for all feeders, the control device determines specific mounting positions for each feeder that account for their position deviations, thereby compensating for variations without increasing mechanical complexity.

AI summary
An information processing device configured to determine a mounting position of a tape feeder to any one of multiple feeder mounting sections formed in a work machine, in which mounting positions of two or more tape feeders configured to supply components of holding target held by two or more holding tools of a work head disposed in the work machine are determined to any one of the multiple feeder mounting sections based on position information indicating supply positions of the two or more tape feeders, so that a difference in an amount of deviation of the supply positions of the two or more tape feeders is within a predetermined range.
