The safety light curtain is also the photoelectric safety protection device (also called safety protector, punch protector, infrared safety protection device, safety grating, etc.).
Safety gratings are also called safety light curtains or infrared photoelectric protection devices in China. Working principle: A transmitter and a receiver, infrared, when blocking any beam, it will give a signal to stop the device, thereby playing a safety protection. The photoelectric safety device generates a protective light curtain by emitting infrared rays. When the light curtain is blocked, the device sends out a light-shielding signal to control potentially dangerous mechanical equipment to stop working and avoid safety accidents.
In modern factories, humans 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, mechanical transmission and handling equipment, hazardous areas (toxic, high-voltage , High temperature, etc.), it is easy to cause personal injury to operators.
While the advancement of industrial automation provides abundant materials for human life, it has gradually become a “killer” that threatens personal safety. The frequent occurrence of production accidents has made the topic of safe production more and more concerned. Tens of thousands of operators are injured by machines every year. In order to avoid human error, ensure the safety of the factory's production process, and improve production efficiency; the regional safety protection light curtain is thus produced. The safety light curtain can reduce the occurrence of accidents in terms of intrinsic safety, which is beneficial to the company itself, the operating workers and the society.
Cyndar's ultra-thin safety light curtains are cheap nationwide, with guaranteed quality, and have a wide range of applications. For example, if a contact safety protection door is installed on a stamping equipment that needs to be continuously fed and retrieved, the operator needs to open and close the protection frequently This not only increases the workload of the operator, but also reduces the production efficiency. In this case, the use of gratings and light curtains is the best choice. When the operator is sending and reclaiming materials, as long as any part of the body blocks the light, the machine will enter a safe state without causing injury to the operator. The density of the light beam determines how large the body part can be detected through the light curtain.
The installation of photoelectric safety protection devices, short-distance safety light curtains and long-distance safety light curtains can effectively avoid safety accidents, avoid the dangers of operators and third parties, reduce the overall cost of accidents, and benefit the company itself, operators and society.
Main application industries: Forging machine tool plants, automobile manufacturers, motorcycle manufacturers, electrical appliances manufacturers, hardware processing plants, plastic machinery plants, paper cutter applications and other industries.
9 precautions when using the safety light curtain:
Cover the industrial safety light curtain with your hand, and observe whether the indicator light changes normally.
During the use of the photoelectric protection device of the punch press, the position of the photoelectric protection device shall not be changed at will.
In the protection zone, if the light curtain is blocked by hand, the machine should be able to stop working immediately.
When the slider is at the bottom dead center (180 degrees), the light curtain is blocked, and the machine tool slider should be able to return.
For a press that can only achieve top dead center protection, when the slider stops at the top dead center, and the slider blocks the light curtain, the next operation cannot be started.
After the mold is replaced, the safety distance and location of the protection device must be adjusted by a special manager.
When disassembling the light curtain and the transmission line, the power should be turned off first, and the operation must be performed by professionals to avoid danger.
Check whether the transmitter and receiver of the safety light curtain are correctly assembled with their respective cables, and whether the terminals of the cables are correctly connected to the power supply and the controller.
The safety light curtain sensor is powered on, and the time curtain sensor starts to self-check, synchronize and self-calibrate. After about 1 second, if the yellow indicator light of the transmitter is stable and all the indicators of the receiver are off, it means that the light curtain sensor enters the normal working state. .
