Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting devices, in particular to a follower module used for cutting profiles with a laser cutting head. Background Art

[0002] With the development of social science and technology, my country's manufacturing industry is facing a transformation towards high-end and intelligentization. As a basic processing, the penetration rate of laser technology in various links of industrial production is also rising. Laser cutting is a technology that uses a high-power density fiber laser beam to irradiate the material to be cut, so that the irradiated part of the material vaporizes to form tiny holes, and as the fiber laser beam moves, the holes are continuously formed to complete the cutting of the material.

[0003] In the actual production and processing process, since the profile cannot be completely flat, there are usually bumps and bumps. In this case, the laser cutting head is required to make corresponding avoidance or following according to the changes in the shape of the workpiece, and to obtain information in real time based on the sensor to determine the need to compensate the corresponding distance. In order to achieve the compensation effect of the laser cutting head, the existing method is to install the laser cutting head on the machine tool X, Y and Z axis drive device for compensation.

[0004] However, in the working scene, when the cross-section of the profile is irregular, it is often necessary to rotate a certain angle for processing, which causes the laser processing direction to deviate from the X, Y and Z axes. This requires the X, Y and Z axes to be linked during the compensation process to synthesize a compensation direction consistent with the laser processing direction to control the laser cutting head to extend and retract in the laser direction.

[0005] Although the compensation structure can achieve a compensation effect, it synthesizes a compensation direction consistent with the laser processing direction through the linkage of the X, Y and Z axes. The implementation process requires calculation first and then separately controlling the movement of the X, Y and Z axes. The calculation is relatively complicated and the compensation efficiency is low, which cannot meet the needs of high-efficiency processing and is not conducive to improving the competitiveness of the enterprise.
