Description

Technical Field

[0001] The present invention relates to the technical field of laser precision cutting, in particular to a laser precision cutting device for aluminum foil processing. Background Art

[0002] During the laser precision cutting operation of aluminum foil, strong reflected light will be generated when the laser is irradiated onto the surface of the aluminum foil; traditional interception devices are often unable to respond to the generation of reflected light in a timely manner, causing the reflected light to easily cause damage to external facilities and devices, such as damaging surrounding optical components, electronic equipment, etc.; some interception structures have low transmission efficiency and use a single gear transmission or simple mechanical structure. It is difficult to achieve rapid and accurate adjustment of the interception position through the reasonable conversion of speed and torque, resulting in poor reflected light interception effect. Equipment failures and losses caused by reflected light are frequent, which not only shortens the service life of the equipment, but also increases maintenance and replacement.

[0003] When laser cutting aluminum foil, metal particles and the mist generated by cutting will mix to form pollutants, causing serious pollution to the laser lens: existing cleaning devices mostly use a fixed cleaning structure, which cannot achieve all-round dynamic cleaning of the lens surface. Metal particles and mist are easily accumulated on the lens surface, affecting the stability of the laser light path; some cleaning methods such as continuous gas injection or manual wiping, due to insufficient cleaning force, lead to residual debris. The accumulation of debris may reflect the laser, which will not only reduce the laser cutting accuracy, but also may cause damage to the equipment itself, resulting in unstable aluminum foil cutting quality, making it difficult to meet high-precision processing requirements.
