Description

[0002] With the development of social technology, China's manufacturing industry is facing the transformation towards high-end and intelligent. As a basic processing technology, the penetration rate of laser technology in all links of industrial production is also increasing continuously. Laser cutting is a cutting processing technology that uses a high-power density fiber laser beam to irradiate the material to be cut, causing the irradiated part of the material to vaporize to form small 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, in order to meet the processing of different types or complex profiles, the laser cutting head is usually installed on a multi-dimensional robotic arm for processing. The processing angle of the laser cutting head is flexibly adjusted through the robotic arm to adapt to different processing scenarios. In order to enable the multi-dimensional robotic arm to rotate in multiple directions and angles, a plurality of rotation modules in multiple directions are provided, and the moving ends of the rotation modules are connected in sequence. The existing connection method generally uses screwing holes from the side to connect with the moving end, resulting in a circle of installation screws at the connection of the robotic arm. And because the diameter of the moving end of the rotation module is smaller than the outer ring of the rotation module, in order to better fit the moving end, the connection part is recessed inward and is not flush with the outer surface of the rotation module. This affects the aesthetics of the product and the integrity is poor. Moreover, since each rotation module is provided with an independent driving device, the driving device and the laser cutting head need to be wired independently. The existing method is external wiring. During the processing movement, various wires affect the aesthetics of the processing equipment, and the externally wired wires are also prone to being scratched and damaged, resulting in a poor use experience of the robotic arm and being not conducive to improving the competitiveness of the product.
