The measuring light curtain is a high-precision optical inspection system, which consists of a series of light beams arranged to form a light curtain. When the measured object passes through this light curtain, it blocks part of the beam and causes a change in light intensity. By detecting this change in light intensity, it is possible to accurately measure the position, size, shape, and other information of the object.
Measuring light curtains have the characteristics of high precision, high speed and high reliability, so they have been widely used in automated production lines, robot positioning, logistics sorting, measuring instruments and other fields. It can realize non-contact measurement, avoid the wear and error that may be brought by traditional contact measurement methods, and improve the accuracy and efficiency of measurement.
Measure the light curtainThe principle of measuring light curtainsIt is the use of optical phenomena such as light interference, diffraction and refraction, through the photoelectric converter to convert the optical signal into an electrical signal, and then through the processing and analysis of the processor, to obtain the parameters of the object. Its accuracy can reach the micron level or even higher.
The measurement light curtain is mainly composed of two parts: the transmitter and the receiver. The emitter is responsible for emitting a light beam, forming a light curtain; The receiver is responsible for receiving the beam of light passing through the object and converting the optical signal into an electrical signal. At the same time, it is also necessary to cooperate with the corresponding processing software and hardware to analyze and process the electrical signal, and finally obtain the parameters of the object.
The dimensional inspection of parts on an automated production line is taken as an example to illustrate the application of measuring light curtains.
In the automated production line, the dimensional inspection of parts is a very important link. Traditionally, the inspection method is by contact, which not only wears out the measuring tool, but also does not have a high degree of accuracy. The advent of measurement light curtains provides a solution to this problem.
When the part passes through the measurement light curtain, the beam is blocked and the receiver receives the change in light intensity. Due to the size and shape of the part, the change in light intensity will also vary. By analyzing these changes in light intensity, the size and shape of the part can be accurately calculated. This non-contact measurement method not only improves the accuracy and efficiency of the measurement, but also avoids the wear and tear of the measuring tool and reduces the maintenance cost.
In practice, measuring light curtains can also be combined with robotics to enable automated, high-precision part inspection. The robot can place the part in the measuring light curtain, complete the inspection automatically, and feed the results back to the line control system in real time. If a non-conforming part is found, the control system can automatically adjust the equipment on the production line to correct the error. This intelligent production method not only improves production efficiency, but also ensures product quality.
In conclusion, the ESCL series of measuring light curtains plays an important role in the dimensional inspection of parts in automated production lines. Through high-precision measurement and non-contact inspection, production efficiency and product quality are improved, and maintenance costs are reduced. In the future, with the continuous progress of science and technology and the expansion of application fields, it is believed that the measurement light curtain will play an important role in more fields and bring more convenience and benefits to our production and life.
