2. Application instructions of laser displacement sensor principle

Laser displacement sensors are often used to measure physical quantities such as length, distance, vibration, speed, orientation, etc. They can also be used for flaw detection and monitoring of atmospheric pollutants.

1. Dimensional determination: position identification of small parts; monitoring of the presence or absence of parts on the conveyor belt; detection of material overlap and coverage; control of the manipulator position (center position of the tool); detection of device status; detection of device position (through small holes); Liquid level monitoring; thickness measurement; vibration analysis; crash test measurement; automobile related tests, etc.

2. Thickness measurement of metal sheets and thin plates: Laser sensors measure the thickness of metal sheets (thin plates). Detection of thickness changes can help find wrinkles, holes or overlaps to avoid machine failure.

3. Measurement of cylinder barrel, simultaneously measuring: angle, length, inner and outer diameter, eccentricity, conicity, concentricity and surface profile. 

4. Length measurement: Place the measured component on the conveyor belt at the designated location. The laser sensor detects the component and measures it simultaneously with the triggered laser scanner, and finally the length of the component is obtained.

5. Inspection of uniformity: Place several laser sensors in a row in the tilt direction of the work piece movement to be measured, and directly output the measurement value through one sensor. In addition, you can also use a software to calculate the measurement value and read it based on the signal or data. The results.

6. Inspection of electronic components: Use two laser scanners to place the component under test between them, and finally read the data through the sensor to detect the accuracy and completeness of the component size.

7. Inspection of the filling level on the production line: The laser sensor is integrated into the manufacturing of filling products. When the filling product passes through the sensor, it can be detected whether it is full. The sensor uses an extension of the reflective surface of the laser beam to accurately identify the filling quality of the filled product and the quantity of the product.

8. Sensors measure the straightness of objects: First, you need 2-3 laser displacement sensors for combined measurement, and then install the 3 laser displacement sensors on a straight line parallel to the production line, and measure according to the measurements you need. accuracy to determine the spacing between the three laser displacement sensors. Finally, you need to make the object move in a direction parallel to the laser displacement sensor mounting line. When the production line and the sensor installation line are parallel, the greater the distance difference measured by the three sensors, the worse the straightness of the object. The smaller the distance difference measured by the three sensors, the smaller the straightness of the object. The better, you can establish a percentage of straightness based on the length of the object you want to measure and the spacing between the three sensor installations, so as to obtain a quantified signal output and achieve the purpose of detecting the straightness of the object.

3. Application of laser displacement sensor in laser welding

Since laser welding is often affected by the flatness of the work piece plane, or the special-shaped structure of the work piece it (such as curved, round or uneven surfaces), it will inevitably affect the laser focus distance, thereby affecting the laser spot, energy and other aspects. Changing the welding process does not meet the needs, so in actual welding applications, automatic focusing technology is the support that users urgently need, and the laser displacement sensor system is used to solve this problem of users. It can not only be used to measure speed , vibration, orientation, and is also mainly used to measure length or height. It can be combined with other control mechanisms to realize the issuance of detection and control instructions and realize linkage control. Therefore, it is often used in automatic focusing systems in laser welding!

In the production and manufacturing of new energy products, especially in the welding of automobiles and power batteries, it is more important to cooperate with the laser automatic focusing system for welding operations. Improving the welding process level of battery products can also improve the safety and quality of batteries in use.
