Embodiment 1
[0044] see Figure 1-4 , a zero-focus compensation method for an intelligent laser cutting head, comprising the following steps:
[0045] S1. The laser cutting head is driven by the cutting head moving device to move up and down, and a magnetic scale is installed on the moving section of the cutting head moving device;
[0046] S2. Read the magnetic grid signal of the magnetic scale through the main control unit MCU, and determine the zero position reference;
[0047] S3. Control the working of the cutting head moving device to drive the laser cutting head to move up and down, thereby driving the focusing lens barrel to move up and down, and stop the movement when the reference returns to the zero point position reference, and record the stay height position of the focusing lens barrel as Y1;
[0048] S4. Control the cutting head moving device to drive the laser cutting head to move up and down, mark the steel plate under the laser cutting head through the laser cutting head,...
