Safety light barriers have a wide range of applications, primarily in industrial automation, ensuring personal safety and enhancing the intelligence of equipment. The following are some common uses for safety light barriers:
- Industrial Machinery Safety
Safety light barriers are primarily used for personal protection on various types of industrial machinery and equipment. For example, on high-risk equipment like punch presses, shearing machines, injection molding machines, and press brakes, if an operator accidentally reaches into a hazardous area, the safety light barrier can immediately detect and bring the equipment to an emergency stop, preventing pinching and cutting injuries.
- Robotic Operation Area Isolation
In workshops where industrial robots operate frequently, safety light barriers are used to demarcate the robots’ operating areas. If a person enters the robot’s range, the system automatically issues an alarm or halts the machine to prevent collisions or injuries. - Intrusion Detection on Automated Production Lines
Safety light barriers are often used at key nodes or passageways in production lines to detect intrusion into hazardous areas. This contactless sensing method enables rapid response, especially at high-speed assembly lines, to prevent accidents. - Anti-Pinching for Automatic Doors and Lifts
Safety light barriers can be used as anti-pinch protection devices on some electric doors, elevators, and lifts. When a person or object is detected in the closing path, the system immediately stops or reverses the opening, effectively preventing pinching injuries. - Volume and Dimension Detection Assistance
Although not its primary function, safety light barriers can also be used in certain situations to detect objects that are too high, too wide, or out of range. For example, in logistics sorting and packaging lines, light barriers can be used to identify and sort out non-compliant goods. - Access Control for Clean Rooms or Special Areas
In areas with strict access requirements, such as food processing, pharmaceutical plants, and electrostatically sensitive areas, safety light barriers can detect unauthorized intrusion and promptly issue an alarm or trigger an automatic access control system. - Safety Assurance for Human-Equipment Collaboration
In smart manufacturing and flexible production, human-machine collaboration is increasingly required. The installation of safety light barriers allows for human-machine collaboration in a safer environment, ensuring that humans are protected from accidental injuries when approaching machinery. - Protection of Warehousing and Logistics Equipment
Safety light barriers are often used around logistics equipment such as automated stackers, shuttle trucks, and forklifts to ensure no one enters the operating tracks and prevent collisions with personnel.
Safety light barriers are not limited to protection; they are also a crucial component in achieving efficient, precise, and safe collaboration within intelligent manufacturing. As automation continues to increase, the application scenarios for safety light barriers are also expanding.
