The application of high-precision laser distance sensor in the quality inspection of smartphone screen installation is a key technology. The position of the smartphone's screen is essential for its proper functioning. To ensure the correct installation of the screen, it needs to be checked using high-precision measuring equipment.
In this case, three LTP high-precision laser displacement sensors were used to measure the installed quality of the smartphone screen. The LTP series laser displacement sensor has micron-level accuracy, and can form a positive reflection measurement effect in the case of 20° deflection. This sensor can measure not only transparent objects but also specular objects, making it ideal for checking the mounting of smartphone screens.
Compared with expensive spectral confocal sensors, the LTP series laser displacement sensors have a great advantage in terms of cost. At the same time, these sensors have a very fast measurement speed and can reach 50kHz. This means that a large number of measurement tasks can be completed in a short period of time, increasing work efficiency.
In order to measure the installed quality of smartphone screens using these laser distance sensors, the sensor first needs to be installed in the appropriate location. Then, place the smartphone in the appropriate position and make sure that the distance between the screen and the sensor is as required. Next, the measurement is carried out by activating the sensor, and the measurement results are obtained using the secondary development of the SDK.
In this way, the installed quality of a smartphone screen can be measured with micron-level accuracy. If the measurement results show that the screen is not installed correctly, it can be detected and adjusted in time to avoid connection errors and ensure that the smartphone is working properly.
In summary, high-precision laser distance sensors play an important role in the quality inspection of smartphone screen installations. They provide precise measurement results and enable measurement tasks to be completed quickly and efficiently. By using these sensors, it is possible to ensure that the smartphone screen is installed correctly, thereby improving product quality and user experience.
