The application scenarios of safety light curtains are very extensive. They are mainly used for personnel safety protection in industrial automation equipment, especially in environments with potential dangers such as mechanical movement, stamping, cutting, and handling. The following are descriptions of several common application scenarios:
- Stamping Machinery and Equipment
On high-speed equipment such as punch presses and shearing machines, operators often need to change molds or pick and place workpieces. Safety light curtains are installed near the working opening. Once a hand or body enters the danger area, the equipment will automatically stop, effectively preventing pinching accidents. - Injection Molding Machines and Forming Equipment
During the mold-closing and mold-opening processes of injection molding machines, the force is extremely strong. If the operator accidentally enters the mold area, serious injuries may occur. By monitoring the mold area in real time with light curtains, it can be ensured that the equipment does not start when personnel are nearby, thus preventing arms from being pinched. - Automated Assembly and Handling Lines
On production lines, mechanical arms or automatic conveying devices operate at high speed. Light curtains can be set between personnel and equipment. When someone enters the designated area, the system stops immediately to prevent personnel from colliding with the machinery or being drawn into the equipment. - Robot Workstations
When collaborative robots or industrial robots perform operations such as handling, welding, and dispensing, light curtains are usually used to set up a safety zone. Once someone enters the robot’s working range, the robot immediately pauses its operation to ensure safety when humans and machines work together. - Packaging and Sorting Equipment
In high-speed packaging, boxing, and sorting processes, the equipment operates frequently and rapidly. When manual intervention is required, light curtains can act as a mechanism to prevent accidental touches, ensuring safe operation and preventing hands from being caught in belts or boxing mechanisms. - Lifting Platforms and Automatic Doors
In places such as automatic elevators, lifting platforms, garage doors, and factory doors, light curtains can be used to detect whether objects or people are in the movement path of the door or platform, preventing accidental pinching or collisions. - Warehousing and Logistics Systems
In automatic warehouses, vertical racks, stackers, conveyor belts, and other systems, light curtains are used for area isolation and safety detection, preventing personnel from accidentally entering automatic handling paths and causing injury. - Laser Cutting and CNC Machines
Laser cutting, plasma cutting, CNC milling machines, and other equipment involve high temperatures and high energy during operation. By setting light curtain protection areas, unauthorized or improper access to the equipment can be prevented, reducing the risk of accidents. - Elevator Shafts and Platform Edges
During construction or maintenance stages, safety light curtains can be temporarily used to detect whether someone is approaching the edge, serving as area protection and alarm. - Education and Demonstration Laboratories
In vocational education, skill training, or equipment demonstrations, light curtains can be used as safety demonstration tools to help students understand the importance of industrial protection.
