Description

technical field

[0001] The invention belongs to the technical field of laser cutting, in particular to a capacitance sensing device and a laser cutting head. Background technique

[0002] With the continuous development of laser technology, the application of laser cutting technology is becoming more and more extensive. In the process of laser cutting, a capacitance value will be generated between the capacitive sensing device and the workpiece to be cut. Through the processing of this capacitance value, the distance between the capacitive sensing device and the surface of the workpiece can be guaranteed, thus solving the problem of the capacitive sensing device and the surface of the workpiece. The problem of collision between workpieces to be cut can be solved, and the quality of laser cutting can also be improved.

[0003] When the laser cutting head emits cutting laser light through the capacitive sensing device for laser cutting of the workpiece to be cut, the capaciti...
