Information

Measuring light curtains are widely used in the smart logistics and warehousing industry. They are used in conjunction with weighing scale labels and labelling machines. They are mainly used in logistics sorting, intelligent warehousing, and cross-border e-commerce packaging inspection occasions.

 

The most basic method is to use the measuring light curtain to detect the height of the objects in transportation, to sort the products or make other password actions. For example, in the process of automobile production, it is necessary to spray paint on the exterior of the automobile. At this time, the measurement light curtain is used. Measuring the light curtain is to measure the shape and size of the object by scanning, that is, to form the shape and size of the object according to the amount of light blocking, and then transmit the obtained data to the spraying control system. The spraying control system is set by software. At the same time, output a signal to the spraying robot to spray the shape of the workpiece; when a workpiece is sprayed, the system will give the next control signal to spray the next workpiece.

 

 

Principle of automatic spraying detection and monitoring:

A photoelectric sensor is an electronic device that senses changes in the intensity of light it receives, including an optical system, an amplifier, and a switching output device. All photoelectric sensors use modulated light to eliminate the possible influence of surrounding light sources. When working, the photoelectric sensor emits light. Like the sensor, it consists of two parts, the emitter and the receiver, which are separated from each other and placed opposite each other, but its overall size is larger and it is a long tube. The detection light generated by the measuring light curtain emitter is not just one beam like ordinary sensors, but an array of light rays is generated at fixed intervals along the length direction to form a "light curtain". In a scanning way, with the controller and its software, Realize the function of monitoring and measuring the shape and size of objects.

 

The light curtain measurement system needs to be equipped with a controller to work normally. The controller uses software for programming and setting, which can provide a variety of scanning modes and detection and analysis modes, and can communicate with PLC or computer through the serial interface to transmit control or scan As a result, it is additionally possible to access a trigger signal to control the scanning process.

 

 

LSM series measuring light curtain is an automatic non-contact infrared device with high precision, accurate data and high efficiency.

The measurement light curtain has a variety of height and width protection area specifications to choose from, the detection height is from 320mm to 2240mm, the detection distance can reach up to 10m, the response time is short, and it has stronger interference suppression ability; the product has a high IP protection level , High measurement accuracy, and can be used normally under harsh working conditions; no blind zone design, comprehensive detection; unique optical and circuit design overcomes light interference; optical synchronous communication, easy installation.
