Abstract

The invention belongs to the technical field of laser cutting, and particularly relates to capacitance sensing equipment and a laser cutting head. The capacitance sensing equipment comprises a mounting seat, a capacitance sensor, a ceramic ring, a nozzle and a collision protection device, the mounting seat is mounted on the capacitance sensor, the ceramic ring is mounted at one end, far away from the mounting seat, of the capacitance sensor, and the nozzle is mounted at one end, far away from the capacitance sensor, of the ceramic ring; the collision protection device comprises a protection sleeve and a first elastic piece, the protection sleeve is connected to the capacitance sensor in a sleeving mode, one end of the first elastic piece is connected with the protection sleeve, and the other end of the first elastic piece is connected with the capacitance sensor; and a side collision buffer space is formed between the inner side wall of the protection sleeve and the outer side wall of the capacitance sensor. The capacitance sensing equipment is simple in structure, small in size, low in manufacturing cost and good in anti-collision capability.

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...
