Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvecomponent pickup speedVSAvoidprocess complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improvecomponent pickup speedVSAvoidpickup accuracy
Core Design Contradiction:
ProductivityVSReliability

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

Inventive Principle:
Principle #23Feedback

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

Inventive Principle:
Principle #10Preliminary action

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.
