Two-dimensional galvanometric laser scanning teaching demonstration device and implementing method thereof

Abstract

The invention discloses a two-dimensional galvanometric laser scanning teaching demonstration device and implementing method of the two-dimensional galvanometric laser scanning teaching demonstration device. The device comprises a two-dimensional galvanometric scanning module, an image track recorder and an upper computer human-computer interface. The human-computer interface is mainly used for drawing teaching demonstration graphics or characters and setting serial port communication. The upper computer human-computer interface comprises a display screen and a control button. The human-computer interface is set in the mode that corresponding commands are sent to the two-dimensional galvanometric scanning module by selecting different control keys according to a function menu on the display screen; the two-dimensional galvanometric scanning module is used for receiving commands of the upper computer operation interface, finishing command track decoding, reflector deflection control and laser switch control; the image track recorder is used for real-time recording and displaying of a scanned image track with a DPS image processor as the core. The device and method are simple in structure, low in cost, free of material consumption cost, free of larger investment and capable of simulating industrial laser scanning instruments to be used for teaching and meeting the teaching requirements.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a two-dimensional vibrating mirror laser scanning teaching demonstration device. Background technique [0002] With the development of laser technology, laser scanning technology is more and more widely used in the field of manufacturing. Laser technology is a new interdisciplinary and cross-industry course. As the main application of laser scanning technology, galvanometer laser scanning is widely used in laser processing, graphic transmission, medical diagnosis, laser demonstration and other fields due to its high precision and high speed. [0003] The essence of the galvanometer scanning technology is to use a high-density, high-power laser source as the main body of processing, and through the reflection or refraction of the two-dimensional galvanometer, the motion of the galvanometer is used to realize the motion of the stationary laser, and finally realize the laser on the workpiece...

AI Technical Summary

Problems solved by technology

[0004] The wide application of galvanometer-type laser scanning technology promotes the learning and research of laser scanning technology. At present, there is no such instrument specially used for teaching and demonstration in China. The laser scanning instruments on the market are mostly used in industrial production, and their prices are relatively high. expensive

In addition, the use of industrial laser scanning instruments for demonstration teaching requires large material loss, special equipment maintenance, and large investment; for this reason, industrial laser scanning instruments are not suitable for practical teaching in universities or vocational schools middle
