Solution Overview

Problem

Existing mounting technologies do not achieve sufficient accuracy in picking up components due to limitations in adjusting the height of suction nozzles, necessitating improved methods for higher precision.

Innovation Solution

A mounting system that includes a component supply section, a mounting section with a pickup member, a measurement section to measure the upper surface height of components, and a lifting and lowering mechanism to adjust the pickup member by a push-in amount greater than the measured height, enabling precise component pickup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the height of the suction nozzle is changed to increase accuracy of holding or mounting, then the accuracy of component holding is improved, but the pickup accuracy is still insufficient due to large dimensional accuracy variations of components

Engineering Contradiction:

Improveholding accuracyVSAvoidpickup accuracy

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The measurement section measures the upper surface height of the component before the pickup operation. This preliminary measurement allows the system to determine the appropriate push-in amount in advance, ensuring accurate pickup despite variations in component dimensions. The control section then sets the push-in amount based on this pre-measured height information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes the push-in amount parameter based on the measured upper surface height of the component. Instead of using a fixed suction nozzle height, the control section adjusts the push-in amount to be larger than the measured height, adapting to each component's specific dimensions to ensure reliable pickup accuracy.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If a fixed push-in amount is used for all components, then the device operation is simple, but pickup accuracy deteriorates when component dimensions vary

Engineering Contradiction:

Improvedevice operation simplicityVSAvoidpickup accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system transitions from a static, fixed push-in amount to a dynamic adjustment mechanism. The control section automatically determines and adjusts the push-in amount based on real-time measurements of each component's upper surface height. This dynamic adaptation maintains high pickup accuracy across components with varying dimensions without requiring manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The measurement section provides feedback about the component's upper surface height to the control section. This feedback loop enables the system to automatically adjust the push-in amount for each component, ensuring optimal pickup accuracy while maintaining simple automated operation without manual calibration.

Inventive Principle:

Principle #23Feedback
