How is Online Precision Measurement Achieved? 

In today's world where large-scale, automated production is the mainstream, performing fast and accurate online 100% inspection of product dimensions has become a key link in ensuring quality and efficiency. Traditional manual measurement methods face bottlenecks in speed, consistency, and data integration. Contact displacement sensor technology, with its high precision, high response speed, and excellent integration flexibility, provides a mature solution to this pain point.

Industry Challenge:

For consumer electronic components represented by items like mobile phone glass covers, the production cycle is extremely fast, and there are strict requirements for thickness and flatness. Traditional calipers or benchtop thickness gauges are inefficient, making it difficult to achieve 100% online inspection, which carries the risk of defective products passing through.

Technical Solution:

Employ contact displacement sensors that can be directly embedded into the production line. Leveraging their high precision and speed, they enable real-time, uninterrupted measurement of workpieces passing through at high speeds.

Technical Advantages:

• Low-Force Contact: Enables stable, non-damaging measurement of glossy glass surfaces.
• Real-Time Data Stream: Measurement data can be synchronized to computers, tablets, or MES systems, enabling real-time monitoring and traceability of production data.
• Multi-Parameter Evaluation: Through flexible construction of measurement units, multi-dimensional quality monitoring such as thickness, flatness, and warpage can be achieved simultaneously.

Industry Challenge:

Workpieces like pipes and shafts require diameter screening after machining. Sampling inspection cannot guarantee batch consistency, while manual 100% inspection is inefficient, becoming a production line bottleneck.

Technical Solution:

Utilize slim displacement sensors. Their compact bodies can be easily integrated onto conveyor guides or at the end of robotic arms to take instant measurements of every workpiece passing through.

Technical Advantages:

• Seamless Embedding: Small size does not occupy production line space, enabling true online measurement.
• Efficiency Leap: Measurement is synchronized with the production cycle, achieving 100% full inspection and completely replacing sampling.
• Data-Driven: Paired with a high-speed counter, it can display and judge dimensional tolerances in real-time, automatically triggering sorting signals, saving manpower and eliminating misjudgments.

Industry Challenge:

Eccentricity in rotating components like engine crankshafts and gears directly leads to vibration, noise, and premature wear, severely affecting product lifespan and performance. Traditional laboratory instrument measurement processes are cumbersome and unsuitable for rapid on-site production evaluation.

Technical Solution:

Integrate high-precision displacement sensors with rotary fixtures to build an online eccentricity measurement station. While the component rotates, the sensor can collect radial data from multiple points.

Technical Advantages:

• Process Control: Transforms post-event laboratory sampling into real-time monitoring within the production process, allowing for early detection of machining deviations.
• Flexible Construction: Measurement stations can be freely designed according to product characteristics, adapting to the flexible production needs of high-mix, low-volume manufacturing.
