As demand for high-quality wood products continues to rise in the domestic market, the wood processing industry is embracing large-scale automation and mechanization. Traditional methods of positioning wood for processing or cutting often rely on mechanical clamps, which offer only coarse alignment. This lack of precision can result in misalignments, compromising the quality of the finished product.

A Smarter Approach to Precision

The LVM2120 3D Laser Profile Sensor from Elco provides a cutting-edge solution to this challenge. By leveraging advanced profile scanning technology, this sensor ensures pinpoint positioning of wood panels, enhancing processing accuracy and minimizing errors. Moreover, its rapid measurement capabilities are perfectly suited for the high-speed demands of modern production lines.

Key Specifications

• Model: LVM2120
• Profile Points: 1456
• Installation Distance: 52 mm
• Measurement Range: 26 mm
• Field of View: 19–23 mm
• Laser Wavelength: 405 nm

How It Works

The LVM2120 operates by scanning the wood panel with its line laser sensor positioned directly above the detection area. The process begins when the sensor receives a trigger signal, initiating a precise scanning operation. The collected data is transmitted to a PLC, which communicates with a servo motor to adjust the panel’s position with exceptional accuracy.

Step-by-Step Detection Process

1. Transport and Rough Positioning: The wood panel is moved to the detection station by a conveyor system. Mechanical clamps provide an initial rough alignment.
2. Laser Scanning: Once the panel reaches the sensor’s detection range, the LVM2120 begins scanning with its laser to determine precise positioning data.
3. Data Transmission: The sensor calculates any deviations between the panel’s actual and intended position, sending this information to the PLC.
4. Precision Adjustment: The PLC uses the data to guide the servo motor, aligning the panel with unparalleled precision for processing or cutting.

Advanced Detection Tools

The system utilizes a profile position tool capable of automatically identifying corner and edge features on the panel. This tool outputs precise XZ coordinates, enabling high-accuracy positioning with a precision of up to 20 µm.

Benefits at a Glance

• Enhanced Quality: Eliminates misalignment issues, ensuring high-quality cutting and processing.
