What is AI Vibration Inspection?
AI vibration inspection is an image-based inspection method that leverages deep learning technology. Specifically, it converts extracted vibration data into images and automatically optimizes the system so that defective areas are flagged as NG. AIによって⾃動的に不良箇所の特徴を捉えてモデルの構築が可能となり、検査でも⾼い精度を実現できます。
The "3 Objectives" of AI Vibration Inspection
Vibration inspection is a critical process that verifies whether product quality conforms to specifications and defined standards.
- Quality Assurance
-
In manufacturing, it is essential to provide "quality assurance to consumers" and, as a supplier, to "comply with the quality standards of customers."
If defective products reach consumers, the risks go beyond functionality and safety — they can lead to recalls and reputational damage, causing serious business losses.
There is also a risk of escalating into serious issues such as customer complaints or suspension of business relationships. AI vibration inspection therefore checks whether
products meet quality standards, playing a critically important role. - Quality Maintenance
-
Continuously checking for inconsistencies in product quality is essential from the perspective of maintaining quality and ensuring stable supply.
Conducting vibration inspection with consistent standards leads to stable quality maintenance. - Quality Improvement
-
While product inspection is essential, it is equally important to improve manufacturing processes and equipment to prevent defects from occurring in the first place.
Through vibration inspection, identifying and addressing the root causes of defects becomes the fundamental objective.
Strengths of AI Vibration Inspection
Standardization of Inspection Criteria
AI (deep learning) can learn from "human sensory judgments" and "subtle defects detected by skilled inspectors," enabling high-accuracy inspection under unified standards.
Inspection Automation Based on Expert Inspector Standards
従来の振動検査システムではオペレーターが属人的にしきい値を設定していたため、検査ラインや担当オペレーターによって検査基準が変わる問題が蔓延していました。 AI vibration inspection, by contrast, recognizes the characteristics of detection targets for stable inspection, eliminating the need for frequent threshold adjustments and enabling "standardization of inspection criteria," as well as "reduction of adjustment workload."
AI Vibration Inspection vs.
Conventional Vibration Inspection Methods
Sensory Inspection
This method involves applying vibration to the inspection target and judging its condition from the resulting data.
Distinguishing subtle differences requires skilled technique, making the inspector's skill and experience essential.
In addition, since factors beyond technical skill — such as changes in physical condition — can also affect results, inspection quality varied from person to person, leading to missed detections and false positives caused by human error
With an AI vibration inspection system, the model learns from historical data to build a system that automatically detects defects.
As a result, missed detections due to human error and ambiguous judgments on difficult-to-inspect products can be detected accurately.
Inspection Examples with AI Vibration Inspection
Finished Product InspectionAutomotive parts, electronics, etc.
Analyzes data obtained by applying vibration to parts or products to classify them as good or defective.
Predictive Maintenance of Production EquipmentFactory machinery, etc.
Monitors time-series data from production equipment to detect early signs of failure and prevent unexpected downtime.
Monitoring of Production Equipment and FacilitiesFactory machinery, etc.
The primary purpose is to confirm that equipment and machinery are operating stably. Continuous monitoring for accident prevention in chemical plants is also possible.
Structural InspectionBridges, utility poles,
tunnel concrete, etc.
Records and analyzes the vibrations generated by impact to inspect structures for abnormalities such as loosening or deterioration.
Do any of these challenges sound familiar?
- Missed detections occur in sensory inspection and you want to standardize criteria and improve accuracy
- Recruiting and training personnel takes too long, so you are pursuing workforce reduction
- Conventional waveform analysis requires significant effort to define rules, and there are limits to its accuracy Feel Free to Contact Us
