In the working environment of machine tools, the role of safety light curtains is essential. Xaori's safety light curtains can effectively prevent the dangerous behavior of operators. Xaori's light curtains have the characteristics of small safety detection distance and fast response. The detection of infrared light signals within a certain time allows workers on the front line of production to work with peace of mind. Because as the production time increases, the operator's actions will produce mechanical behavior and the brain is prone to hallucinations. This happens when one thing is repeated. The role of the light curtain is to prevent the operator's mechanical behavior and operation errors. The special alarm sound can wake up operators and remind them to pay attention to safe and reasonable operation. When appropriate, they can stop and rest for a period of time. This is an essential link. It is not possible to blindly pursue production efficiency and ignore the safety of workers. From the perspective of long-term development of the enterprise Such an approach is also unreasonable.
