When designing Auto Parts QR Code Marking Machine in non-standard way, it is very important to improve its anti-interference ability to ensure stable operation in complex automobile production environment.
First of all, the electrical system is the key. Using high-quality electromagnetic shielding materials to make the shell of the marking machine can effectively block the intrusion of external electromagnetic radiation. For the internal circuit, reasonable wiring, reduce the crossing and winding between the lines, and reduce the possibility of electromagnetic induction coupling. At the same time, install a power filter to filter out the clutter and high-frequency interference signals in the power supply, and provide a stable and pure power supply for the equipment. On the signal transmission line, use shielded cables and ensure that the cables are well grounded to prevent the signal from being distorted by external interference during transmission.
The mechanical structure should not be ignored either. Optimize the overall structural design of the marking machine to improve its mechanical stability and seismic resistance. Use high-strength materials and a reasonable structural frame to reduce the impact of mechanical vibration on marking accuracy. For key components, such as the marking head and motion platform, precise guide rails and transmission devices are used, and appropriate shock absorption treatment is performed, such as installing shock-absorbing pads or using shock-absorbing springs, etc., to reduce the interference of external vibration on the equipment.
The optical path system also requires special design. An optical isolator is set between the laser generator and the marking head to prevent external light from interfering with the laser optical path. Ensure that the optical path is well sealed to prevent dust, water vapor and other impurities from entering the optical path system and affecting the transmission and focusing of the laser. For the modulation and control circuits of the laser, chips and components with strong anti-interference ability are used, and reasonable shielding and grounding treatment are performed.
In addition, software algorithms can also play an important anti-interference role. Advanced digital signal processing algorithms are used to monitor and process the signals in the marking process in real time to remove the influence of interference signals. For example, noise interference is removed by filtering algorithms, and marking errors caused by interference are corrected by error compensation algorithms. At the same time, multiple protection mechanisms are set for the software system, such as data verification and fault-tolerant processing, to ensure that the system can run stably when interfered, without freezing or data loss.
In the auto parts production workshop, some environmental improvement measures can also be taken to reduce interference. For example, the electrical equipment in the workshop can be reasonably arranged to reduce the concentrated use of high-power equipment and reduce the intensity of electromagnetic radiation. Keep the workshop clean and dry to reduce the impact of dust and water vapor on the marking machine. Regularly maintain and service the marking machine, check whether the connection of each component is loose, and clean up the impurities in the optical path system and mechanical parts in time to ensure that the equipment is always in good operating condition. Through the above measures, the anti-interference ability of the Auto Parts QR Code Marking Machine in non-standard design can be significantly improved, ensuring that it can work stably and accurately in a complex production environment.
