Safety gratings (also known as safety protectors, punch protectors, photoelectric, and infrared safety protection devices) generally exist in pairs and are divided into transmitters and receivers. The light source is infrared. visible light.

For equipment without safety gratings, if an accident occurs, it can range from scratches to severe injuries to fingers and hands.

Safety gratings are used to prevent operators from making mistakes while operating machines. Common equipment such as punches, hydraulic presses, die-cutting machines, shears, winding machines, etc. can be used in daily life. The only thing that comes into contact is the elevator.

The same principle is used in elevators, but you will encounter the problem that the light beams installed in some elevators are not dense. For example, if you block the middle of the elevator door with your hand and it still closes, this kind of light beam is not dense. , the denser the beam, the higher the cost.

The safety grating is composed of a transmitter and a receiver. The transmitter will transmit a set of infrared beams, and the receiver will include many light sensors. If the object is between the transmitter and the receiver, If the receiver cannot receive a complete signal, it will send a stop signal to the monitoring device.

The light beams sent out by the safety grating transmitter are sequential and sent out at a specific frequency. The detector can only receive specific pulse waves of specific frequencies sent by the transmitter, thus avoiding the influence of other infrared light sources and improving its applicability in security systems.

Generally, safety light barriers are connected to safety relays. If an object is detected, the source of power that causes harm will be automatically removed. In conjunction with a safety relay, the function of the safety grating can be temporarily suspended, allowing objects to pass through the safety grating without generating a protection signal. This is suitable for some semi-automatic processes.

In modern factories, people and machines work together on some potentially dangerous mechanical equipment, such as stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, and mechanical transmission and handling. Equipment and hazardous areas (toxic, high pressure, high temperature, etc.) can easily cause personal injury to workers. Safety grating is an advanced technology to protect workers around various dangerous mechanical equipment. Compared with traditional safety measures, such as mechanical fences, sliding doors, pullback limits, etc., safety light barriers are freer, more flexible, and can reduce operator fatigue. By minimizing the need for physical protection, safety light barriers simplify routine tasks such as installation, maintenance and repair of equipment.
