Unlocking Infinite Possibilities in Industrial Scenarios with Precision Light: The MLD Series Laser Displacement Sensors

2025.11.13

In the wave of intelligent manufacturing, laser displacement sensors have long been the "invisible engineers" in industrial automation, robot control, and precision machining. With their non-contact, high-precision, and highly stable measurement capabilities, they transform minute changes in the physical world into digital signals, providing equipment with "sensing power" and injecting "intelligent soul" into production.

Whether it's precise positioning of robotic arms on lithium battery production lines, workpiece size measurement in 3C workshops, or thickness detection of transparent glass, AKUSENSE sensors can solve industry pain points with "millimeter-level accuracy" and "millisecond-level response," becoming a trusted "measurement tool" for over 20,000 manufacturers worldwide.

 

 

Classic Application Scenarios

 

① Dispensing Height Measurement in Dispensing Machines

    MLD25

The MLD25 laser displacement sensor measures height and feeds the data back to the host computer for Z-axis positioning, providing micron-level measurement accuracy.

The system calculates the optimal focal length for dispensing from the dispensing valve based on the measured height and compensates for the Z-axis valve height in real time to prevent needle collisions or dispensing abnormalities, ensuring dispensing accuracy.

 

 

② Quantity Counting of Foam Trays

    MLD15

Using the height data obtained after the target object passes under the laser, the system counts the number of items. The MLD15 series can be installed over a distance of 280mm, providing a wider measurement range. It can be installed in a position that will not interfere with the device, and even if the size changes with the product, there is no need to readjust the sensor head position.

 

 

 

③ Horn Vibration Measurement in Ultrasonic Splicing Machines

    MLD33

Measures the horn vibration of ultrasonic splicing machines. This confirms whether the specified amplitude has been achieved when replacing the horn. The sensor is compact, easy to install and remove, and convenient to use.

 

 

 

 

④ Analyzing Stamping Motion

    MLD25

The stamping stroke can cause stretching to fail, leading to cracks. Using a long-range laser displacement sensor shortens the condition setting time.

 

 

 

 

 

⑤ Tire Vibration Measurement

    MLD33

Measuring high-speed rotating tires requires high-speed sampling. The MLD33 series achieves stable measurement of black rubber with a response time as fast as 1.5ms.

 

 

 

 

⑥ Water Polishing Robot Position Correction

    MLD35

Measures the vehicle body height and feeds it back to the robot's contour control. It is less affected by differences in surface condition and color after painting, achieving stable measurement.

 

 

 

 

⑦ Detecting Double Sheet Feed of Blanks

    MLD25

Detecting double sheet overlap of blanks before stamping prevents mold breakage. Even with variations in the surface condition of the blanks from batch to batch, stable detection is possible.

 

 

 

 

⑧ Detecting Double-Sheet Blanks

    MLD15

Overlapping multiple sheets of material to manufacture plywood can cause thickness deviations. By installing a laser displacement sensor upstream in the manufacturing process to measure thickness, yield and product quality can be improved.

 

 

 

⑨ Measuring the Thickness of Transparent Glass Plates

    MLD33-L (Positive Reflection)

The laser displacement sensor (positive reflection type) emits a laser to the surface of a transparent glass plate. Utilizing a positive reflection optical path design, it accurately captures the reflection signal from the upper surface, effectively avoiding interference from the lower surface reflection.

 

Linear accuracy reaches ±0.2% F·S, and repeatability is 1μm. It is suitable for thickness and flatness detection of ultra-thin transparent materials such as mobile phone glass and circuit board glass, balancing high precision with industrial environment adaptability.

 

 

 

 

In the wave of Industry 4.0, AKUSENSE has always adhered to "precision intelligence + AI sensing" as its technological foundation, integrating innovation into every product. Whether it's the standard, universal "compact and easy-to-use" or the high-precision, all-around "full-scenario coverage," we are always committed to supporting users in enhancing the market competitiveness of their devices and becoming industry leaders.
