Engineers expect the equipment to achieve real-time detection of screw tightening, ensuring that the screws are not too deep to damage the material and screws, nor will they fall off due to being too shallow.
In this issue, Xiao Ming will share with you the classic application case of Meiji MLD25 series sensors in detecting the depth of automotive screw tightening:
Application scenario
Install the sensor directly above the screw, detect the output in real time, and determine whether the screw is in place. Once it is in place, send a signal to drive the equipment to stop to prevent the screw from being too deep and damaging the screw and material
1. The required error is within 0.5mm. Drilling too deep may damage the material and screws, while drilling too shallow may cause detachment
2. The surface of the material is made of highly reflective metal
3. Non contact measurement is required
4. The sensor needs to be installed on a screw tightening shaft, which should be lightweight and easy to use
1. 0.5mm accuracy requirement
The customer expects the sensor to accurately measure the depth of screw tightening, with an error controlled within 0.5mm.
This is because the depth of screw tightening directly affects the quality and safety of the product. If the screws are screwed too deeply, it may damage the material and screws, and even lead to the scrapping of the entire product; If the screw is too shallow, it may not be able to firmly fix the material, resulting in the product falling off or loosening during use.
2. Non contact measurement
Due to the highly reflective metal surface of the material, the customer requests that the sensor be able to use non-contact measurement methods to avoid damage or contamination to the material. Meanwhile, non-contact measurement can also improve the accuracy and stability of the measurement, reducing errors caused by contact.
3. Real time detection and feedback
The customer expects the sensor to detect the status of screw tightening in real time and provide feedback to the control system. In this way, the control system can adjust the working status of the tightening shaft in real time based on sensor data
This can not only improve production efficiency, but also avoid problems of excessive or insufficient tightening.
4. Easy installation and reliability
The customer requires the sensor to be easy to install and debug, with a small size that can be easily installed on a screw tightening shaft
Recommended Selection
In response to the above needs of customers, the Akusense standard laser displacement MLD25 series can be selected, with high accuracy (linear accuracy ± 0.1% F.S, repeatability of 10um), suitable for detecting height information in this type of product assembly.
1. High precision measurement
The MLD25 sensor has high-precision measurement capability, with a linear accuracy of ± 0.1% F.S and a repeatability of 10um. It fully meets the customer's requirements for 0.5mm error control.
2. Non contact measurement
The MLD25 sensor adopts the principle of laser measurement and achieves non-contact measurement. This can not only avoid damage or contamination to materials, but also improve the accuracy and stability of measurements.
3. Real time detection and feedback
The MLD25 sensor can detect the tightening status of screws in real time and transmit data to the control system through a high-speed communication interface. The control system confirms whether the screw is within the specified depth range based on sensor data.
4. Easy installation and reliability
The MLD25 sensor has a compact structure and an easy to install design, making it convenient to install on a screw tightening shaft. At the same time, the sensor adopts high-quality materials and advanced manufacturing processes, with high reliability and stability, and can maintain stable performance in harsh working environments.
The above is an application example of Akusense laser displacement sensor MLD25 for real-time detection of screw tightening status in automotive automation production.
Through the advantages of high-precision measurement, non-contact measurement, real-time detection and feedback, as well as convenient and reliable installation, this solution provides an efficient, accurate, and reliable screw tightening detection solution for the automotive manufacturing industry. This not only improves production efficiency and quality level, but also brings significant economic and social benefits to customers.
