Solution Overview
Problem
Industrial pick and place machines face challenges in real-time monitoring and predictive maintenance of nozzle performance, leading to increased downtime and defect rates due to mis-picks and nozzle degradation, as existing methods require manual data collection and integration, which hinders effective real-time process monitoring and analysis.
Innovation Solution
A nozzle performance analytics system that streams production data from pick and place machines to a cloud platform, generating performance vectors based on rejects and mis-picks, and predicts performance degradation by analyzing vector trajectories, enabling proactive notifications and control adjustments to mitigate issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data collection and integration methods are used for nozzle performance monitoring, then device complexity is reduced, but real-time monitoring capability and productivity are worsened
Solution Approach 1:
The patent replaces manual data collection methods with an automated data streaming system that continuously transfers production data from pick and place machines to a cloud platform. This substitution of mechanical/manual processes with automated digital systems enables real-time monitoring while managing complexity through cloud-based infrastructure.
Solution Approach 2:
The patent introduces a cloud platform as an intermediary between the pick and place machines and the analysis system. This intermediary handles data aggregation, storage, and processing, allowing real-time monitoring capabilities while distributing system complexity across multiple components rather than concentrating it in a single complex system.
2Reliability
If performance vector analysis is implemented for predictive maintenance, then reliability is improved, but device complexity and loss of time for data processing increase
Solution Approach 1:
The patent implements performance vector analysis that tracks nozzle performance metrics over time and identifies trends before failures occur. By performing preliminary analysis of performance data and detecting degradation patterns early, the system enables predictive maintenance that improves reliability while the cloud-based architecture manages processing complexity.
Solution Approach 2:
The patent establishes a feedback loop where performance data from nozzles is continuously collected, analyzed through performance vector generation, and used to generate notifications when degradation thresholds are approached. This feedback mechanism improves reliability by enabling timely maintenance actions while the automated nature of the feedback process manages data processing complexity.
3Manufacturing precision
If continuous data streaming and analysis is performed on nozzle performance, then manufacturing precision is improved through reduced defects, but use of energy and device complexity increase
Solution Approach 1:
The patent extracts only the critical performance metrics needed for nozzle performance assessment (reject counts, performance vectors) from the total production data stream. By selecting and analyzing only the essential data elements rather than processing all available data, the system reduces energy consumption while maintaining the ability to detect defects and improve manufacturing precision.
Solution Approach 2:
The patent transforms raw production data into performance vectors that represent nozzle performance in a simplified parameter space. This parameter transformation enables efficient analysis of manufacturing precision indicators while reducing the computational energy required compared to analyzing raw data directly.

AI summary
A pick and place nozzle performance analytics system streams production data from pick and place machines used in electronic assembly to a cloud platform as torrential data streams, and performs analytics on the production data to track, visualize, and predict performance of individual nozzles in terms of rejects or miss-picks. The analytics system generates a performance vector for each nozzle based on the collected production data, the performance vector tracking both the accumulated rejects and the percentage of rejects as respective dimensions of an x-y plane. The system monitors and analyzes the trajectory of this vector in the x-y plane to predict when performance degradation of the nozzle will reach a critical threshold. In response to predicting that nozzle performance degradation will exceed a threshold at a future time, the system can generate and deliver notifications to appropriate client devices.
