Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of safety protection, specifically is a two-partition protection light curtain. BACKGROUND

[0002] In the field of modern industrial automation, safety protection and efficient operation are two key factors indispensable on the production line. With the increasing production demand, higher requirements are put forward for the performance and efficiency of safety protection equipment. The traditional single work platform operation mode has been unable to meet the needs of modern production lines. On the one hand, the design of single work platform limits the parallel processing capacity of the production line, resulting in low work efficiency. In single platform operation, the operator needs to wait for the previous task to be completed before starting a new task, which not only wastes valuable time resources, but also limits the overall output of the production line. On the other hand, the safety hazards of single work platform cannot be ignored. The frequent entry and exit of operators into the work area increases the risk of being injured by machines or equipment. In addition, environmental factors such as smoke and dust not only threaten the health of operators, but also may cause serious safety problems such as fire. Traditional safety protection equipment often fails to provide comprehensive and effective protection when faced with these problems. More seriously, traditional conveyor belts and other equipment may produce errors after long-term use, which not only affects the quality and precision of products, but also may threaten the stable operation of the entire production line.
