Description

TECHNICAL FIELD

[0001] The utility model relates to dust removal field especially, a kind of dust removal device for three-dimensional scanning galvanometer field lens. BACKGROUND

[0002] With the continuous progress of science and technology, three-dimensional scanning technology is widely used in industrial manufacturing, cultural heritage protection, medical treatment, virtual reality and many other fields, and the performance of three-dimensional scanning galvanometer field lens, as a key component in three-dimensional scanning system, directly affects the accuracy, speed and reliability of the entire scanning system.

[0003] However, the traditional three-dimensional scanning galvanometer field lens will greatly interfere with the focusing process of laser beam when dust particles are attached to the surface of the field lens, and will also cause the position of the scanning point to deviate. Long-term accumulation of dust will gradually reduce the optical performance of the field lens and accelerate the wear of the field lens.

[0004] Therefore, in view of the problems of the traditional three-dimensional scanning galvanometer field lens affecting scanning accuracy and reducing equipment life, a three-dimensional scanning galvanometer field lens dust removal device can be designed. By increasing a primary filter screen, a secondary filter screen, a fan and an exhaust duct, larger particle dust, impurities and other pollutants can be preliminarily filtered, and smaller particle pollutants can be further removed. Accelerating air flow helps to timely remove heat generated during equipment operation, prevents heat accumulation and blows away dust attached inside. It can guide air containing heat and pollutants to a specific discharge location to ensure that hot air and impurities such as dust can be smoothly discharged outside the equipment, avoiding their retention inside the equipment to affect equipment performance and cleanliness of the working environment.
