Application of the Wide Scanning Range Light Curtain in Industrial Automation Production Line

In this scenario, the wide scanning range light curtains form an invisible "safety barrier" around the equipment to achieve real-time monitoring of people and objects. When an operator approaches a dangerous area or an object accidentally enters the working area of ​​the equipment, the light curtain will immediately detect and send a stop signal to ensure that the equipment stops running and avoid accidents. The following discusses its application in detail from several aspects:

In industrial automation production lines, robotic arms undertake tasks such as high-precision material handling, assembly, and welding. Due to the complex motion path of the robotic arm and high precision requirements, any external interference will lead to misoperation or equipment damage, or even personal injury. The wide scanning range light curtain can be set in the working area around the robotic arm to prevent operators from accidentally entering the range of motion of the robotic arm. When the safety light curtain detects that someone or other objects have entered the dangerous area, the system will immediately stop the movement of the robotic arm to avoid collision or misoperation.

The conveyor belt is a key component in the production line, responsible for moving workpieces or products from one processing point to the next. The continuous operation of the conveyor belt is dangerous, especially when materials or tools fall, which may cause equipment failure or personal injury. The wide scanning range light curtains can be arranged on both sides or above the conveyor belt. When a foreign object is detected falling into the conveyor belt, the light curtain will send a signal to stop the operation of the conveyor belt to ensure the safety of equipment and personnel.

On the production line, fixtures are used to fix workpieces to ensure their stability and precision on the robot arm or conveyor belt. However, in an efficient operation environment, the displacement of workpieces or the failure of fixtures will bring safety hazards. The multi-faceted protection function of the safety light curtain can monitor these areas in all directions. Once it is detected that the fixture fails to properly fix the workpiece or the workpiece accidentally falls off, the system will respond immediately to prevent the equipment from continuing to operate and causing accidents.

As can be seen in the figure, a large number of power lines and control lines are arranged next to the equipment. These lines provide power and signal transmission for the equipment's sensors, controllers, robot arms, etc. The wide scanning range light curtain protection can monitor the safety status of these cables to prevent people or materials from accidentally touching the cables or damaging the lines, which may cause equipment shutdown or safety accidents.

The wide scanning range light curtains have a wide coverage range and can easily monitor a large area of ​​the entire automated production line. This is particularly applicable to production lines with a wide distribution of robotic arms, conveyor belts and other automated equipment, reducing the use of traditional mechanical guards and improving work flexibility and safety.

The wide scanning range light curtains have a high-speed response capability, which can detect intrusion objects in a very short time and send a shutdown signal. Such a fast response is essential to ensure the safety of mechanical equipment and personnel, especially when the production line is running at high speed, to avoid accidents.

Compared with traditional mechanical guards, the wide scanning range light curtains use a non-contact photoelectric detection method, which does not cause any physical obstruction to the normal operation of the equipment. This non-contact protection not only ensures the continuous and efficient operation of the equipment, but also improves operational flexibility.

Modern industrial automated production lines usually have multi-dimensional workspaces, and the wide scanning range light curtains can provide protection in multiple directions as needed. Whether it is on the front, side or top of the production line, the light curtain can be flexibly arranged to maximize coverage of the dangerous area.
