Principle and Application Scenarios of Laser Displacement Sensors
13 Apr 2024

  As the name suggests, laser displacement sensors utilize laser technology for measurement. Currently, there are two main principles for laser displacement sensors: the laser triangulation method and the laser echo analysis method. The laser triangulation method is primarily used for high-precision short-distance measurements, while the laser echo analysis method is employed for long-distance measurements. Nowadays, in industrial robotics, the triangulation method is predominantly used, offering a maximum linearity of up to 1 micron and a resolution as high as 0.1 micron.   The principle of the triangulation method involves directing visible red laser light through a lens onto the surface of the object being measured. The laser light reflected by the object is then captured by a receiving lens and detected by an internal CCD linear array camera. Depending on the distance, the CCD linear array camera operates from different angles to "see" this light spot. With this angle and the known distance between the laser and the camera, a digital signal processor can calculate the distance between the sensor and the object being measured.   Simultaneously, the beam undergoes analog and digital circuit processing at the receiver's position, and the microprocessor analyzes and measures the corresponding output values. Standard data signals are output proportionally within the user-set analog window. If using switch output, it will be activated within the set window and deactivated outside it. Additionally, the detection window for analog and switch outputs can be independently configured.   The principle of echo analysis involves the laser emitter sending a million laser pulses per second to the detection object and receiving them back at the receiver. The processor calculates the time required for the laser pulse to reach the detection object and return to the receiver, providing distance values. The output value is the average of thousands of measurement results, obtained using the so-called pulse time method. The laser echo analysis method is suitable for long-distance detection but offers lower measurement accuracy compared to the laser triangulation method, with

  Welding is the "tailor" of the metal processing industry, playing an important role in overall industrial manufacturing. However, with the development of industrial technology, manual welding has been greatly restricted due to harsh working environments, high labor intensity, and increasing labor costs. This has led to manual welding being gradually replaced by automated welding.   Automated welding uses sensing and measurement technology to detect the position deviation of the welding gun from the center of the weld seam. This deviation is then calculated by a computer and adjusted in real-time by a welding robot, ensuring the welding gun is always aligned with the weld seam, thereby achieving automated welding. At this point, it becomes inevitable to find a good weld seam tracking system manufacturer. So, how do you choose the right manufacturer for weld seam tracking?   Choosing a weld seam tracking manufacturer should focus on company qualifications, production technology, service level, and more.   The level of weld seam tracking technology can improve production efficiency and reduce labor costs, and it is directly related to the manufacturer's level.

  With the continuous development of manufacturing, the demand for welding technology in product manufacturing is increasing. In order to improve the quality of welded products and reduce the labor intensity and working environment for workers, welding automation is an important direction. However, many welding operations have particularities, such as easy deformation of welded workpieces or inconsistent joints, which pose challenges to automated welding. The weld seam tracking system is specifically developed to address such issues. Let's take a closer look at the structure of the laser vision weld seam tracking system.   Structure of Laser Vision Tracking System   The laser, serving as a structured light source, projects laser stripes onto the working surface below the sensor at a predetermined angle. The CCD directly observes the stripes beneath the sensor. The sensor is installed at a predetermined distance in front of the welding torch, allowing it to observe the weld seam. During tracking, welding speed and forward distance are used to calculate the delay time, ensuring that the welding torch progresses along the weld seam.   Laser Vision Sensor   Compact laser vision sensors are typically installed on the welding torch. A laser diode inside the sensor emits a visible laser beam, which, after passing through an aperture, becomes a fan-shaped light band projected onto the workpiece. The sensor contains a CCD camera set at an angle relative to the laser diode, capturing the reflected light from the workpiece surface to image the geometric contour of the joint onto the CCD. Utilizing optical triangulation, horizontal features can be detected, and the height between the sensor and the workpiece can also be determined.   The role of the sensor is to convert the measured physical quantity into a useful electrical signal corresponding to it, to meet the requirements of information processing and control. The control system analyzes and processes the signals from the sensor to obtain control signals. The actuator typically consists of motors and cross sliders, with the servo motor controlled by the control signal.   Image Preprocessing   Image processing in
