Key Role and Application Case Analysis of Safety Light Curtains in New Energy Vehicle Manufacturing
Jul 14,2025
With the booming development of the new energy vehicle manufacturing industry, production safety and efficiency have become the core focus of enterprises. As a key equipment in the field of industrial automation safety protection, safety light curtains are playing an indispensable role in building a solid safety line for new energy vehicle manufacturing and helping the industry move forward efficiently.
New energy vehicle manufacturing covers many complex and precise production links. From battery production to vehicle assembly, each step is accompanied by potential safety risks. In the battery production process, high-voltage, high-temperature environments and the high-speed operation of robotic arms pose a threat to the safety of operators; in the vehicle assembly workshop, automated equipment and workers work together, and safety accidents may occur if a little carelessness. Based on the principle of photoelectric induction, the safety light curtain forms a protective light curtain by emitting and receiving infrared rays. Once an object blocks the light in the light curtain, the light curtain can quickly sense it and immediately send a signal to the equipment control system to prompt the equipment to stop running urgently, thereby effectively avoiding contact between personnel and dangerous equipment and preventing accidents.
The application of safety light curtains is extremely common in the production of new energy vehicle batteries. In the battery module assembly workshop of a new energy vehicle company, the robotic arms here need to accurately grab and install parts at extremely high speeds. In the past, even with strict operating procedures, it was still difficult to completely eliminate the risk of workers being injured by accidentally approaching the working area of the robotic arm. After the introduction of the safety light curtain, the situation has been greatly improved. The safety light curtain is installed at the boundary of the dangerous area around the robotic arm to monitor the approach of personnel in real time. When a worker accidentally enters a dangerous area and blocks the light curtain, the light curtain is triggered instantly, the equipment brakes urgently, and the robotic arm immediately stops moving.
In the final assembly workshop of complete vehicles, the safety protection of automated production lines is also inseparable from safety light curtains. Many automated equipment work together on the assembly line, and workers need to move frequently between different stations. Safety light curtains are deployed in various dangerous areas of the production line, such as equipment entrances and exits, and around moving parts. A new energy vehicle assembly plant installs safety light curtains at key positions on the production line and deeply links them with the PLC system. When it is detected that personnel enter a dangerous area, the light curtain responds quickly, and the PLC system immediately controls the production line to stop running and sends an alarm to alert.
In addition to ensuring personnel safety, safety light curtains also play an important role in improving production quality. In the high-precision assembly of new energy vehicle parts, some safety light curtains with high-precision detection functions can assist in detecting the assembly accuracy of parts while ensuring safety. For example, at the motor assembly station, the light curtain can accurately determine the positional deviation of parts by detecting the light occlusion, provide real-time feedback to the operator, and help them adjust the assembly operation in time to ensure that the product quality meets high standards.
With the continuous development of the Industrial Internet of Things (IIoT) technology, safety light curtains are also keeping pace with the times. The new generation of smart safety light curtains is equipped with communication interfaces, such as EtherCAT, Profinet, etc., which can be easily connected to the Manufacturing Execution System (MES). This enables companies to obtain real-time operating status data of safety light curtains and remotely monitor and maintain equipment. When a safety light curtain fails or an abnormal alarm occurs, the MES system can send a notification as soon as possible, and maintenance personnel can respond and handle it in time to avoid production stagnation caused by equipment failure. At the same time, by analyzing the operating data of the light curtain, companies can also discover potential safety hazards and production process optimization points, and further improve production management levels.
Safety light curtains have become a key technical means to ensure personnel safety, improve production efficiency and product quality in the manufacturing process of new energy vehicles. From battery production to vehicle assembly, the wide application of safety light curtains provides a solid support for the steady development of the new energy vehicle industry. With the continuous innovation and upgrading of technology, safety light curtains will play a more important role in the field of new energy vehicle manufacturing, helping the industry move towards a higher quality and safer development stage.
