Therefore, the anti-collision protection device is mostly arranged inside the existing three-dimensional five-axis laser head, so that the problems of damage to workpieces, laser heads and even lasers caused by collision of the laser heads and the workpieces in the existing complex space curved surface machining process are solved.
However, in the practical application process, the existing anti-collision protection device mostly adopts a hard connection breaking design or a micro switch design which is arranged in the middle of the laser head, but when the hard connection breaking design is adopted, the hard connection assembly needs to be replaced when the laser head is repaired each time because the hard connection breaking design needs to break the connection part after the hard connection collision, so that the anti-collision protection device is expensive. In addition, when the micro switch is adopted, as the structure for sending out collision electric signals, such as the micro switch, the electromagnet and the like, is directly arranged at the mechanical anti-collision structure, the whole anti-collision protection structure can be more complex, the signal sending structure is easy to be bumped in the process of sending out the collision by the laser head, and the error touch phenomenon is generated when the laser head has larger acceleration.
