Suction Nozzle Control for Multi-Component Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting devices require complex processes to pick up multiple components simultaneously, leading to inefficiencies in component pickup and positioning.
Innovation Solution
A control device and mounting system that selects a combination of suction nozzles with tip intervals within a predetermined range, ensuring multiple components can be picked up in the same process by adjusting nozzle positions based on deviation amounts to maintain optimal alignment and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction nozzle is rotated and the component pickup position is changed to pick up multiple components simultaneously, then the productivity is improved, but the device complexity increases due to complex processes for changing nozzle positions and component supply positions
Solution Approach 1:
The system performs preliminary measurement of the distance between nozzle tips before component pickup. Based on this measurement, the control device determines in advance whether the current nozzle combination is suitable for simultaneous pickup of multiple components, thereby avoiding complex position adjustments during the pickup process
Solution Approach 2:
The invention replaces mechanical adjustments of nozzle positions and component supply positions with a control system that uses measured distance information to determine suitability of nozzle combinations. This substitutes complex mechanical processes with automated control based on predetermined ranges
2Productivity
If the suction nozzle is rotated and the component pickup position is changed to pick up multiple components simultaneously, then the productivity is improved, but the reliability decreases because the complex process makes it harder to ensure accurate pickup
Solution Approach 1:
The system measures the actual distance between nozzle tips and uses this feedback information to determine whether the nozzle combination is suitable for simultaneous pickup. This feedback mechanism ensures that only combinations within the predetermined range are selected, maintaining high reliability
Solution Approach 2:
The suitability of nozzle combinations is determined in advance based on measured distances before the pickup operation. This preliminary determination ensures that reliable combinations are selected without requiring complex adjustments during the actual pickup process

AI summary
A control device is used for a mounting device with a mounting head including at least a first holder on which a first pickup member is installed, and a second holder on which a second pickup member is installed, and configured to pick up components supplied from a component supply section and mount the components. The control device includes a control section configured to acquire a first deviation amount of a tip of the first pickup member and a second deviation amount of a tip of the second pickup member and select a combination of the pickup members in which an interval between the tips of the pickup members that is obtained based on the first deviation amount and the second deviation amount falls within a predetermined range.
