Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of processing, and more particularly relates to a laser processing servo device and a processing equipment. BACKGROUND

[0002] The laser head is generally provided with a capacitive sensor for sensing the distance from the nozzle of the laser head to the surface of a workpiece. When the surface of the workpiece is uneven, the capacitive sensor will convert the distance signal into an electric signal and feed back to the height adjustment system, which will control the laser head to move up and down following the surface of the workpiece, so that the nozzle of the laser head and the laser focal point maintain a certain distance from the surface of the workpiece, and high-quality laser processing is achieved.

[0003] The foregoing process is usually completed by a servo device connected with the Z-axis of the machine tool. The servo device realizes the up-and-down movement by relying on the Z-axis of the machine tool. However, the Z-axis of the machine tool has a heavy load, and the height adjustment system and the machine tool system must be interlocked to control the Z-axis, so that only one of the two can control the Z-axis movement, resulting in low processing efficiency.
