Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a novel laser lens. Background Art

[0002] Laser lighting has a wide range of applications and plays a role in many fields. For example, in laser printers, laser lighting can accurately focus the light beam to make the printing effect clearer. In addition, in the field of medical beauty, laser lighting is also very important and is widely used in laser wrinkle removal, freckle removal and other treatment processes, which helps to improve the treatment effect and accuracy. In scientific research, laser light sources are often used for precise measurements and experimental operations to provide scientists with accurate data support.

[0003] Taking the laser lens used in the laser electric eye as an example, the existing lens surface is generally processed by mirror polishing. The lens surface formed by this processing method has a bright spot in the center area of ​​the light emitted. The center area of ​​the light spot projected onto the surface of the object is prone to reflection, resulting in the laser electric eye being unable to accurately capture the point of the object. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a new type of laser lens, which can solve the problem of bright spots appearing in the center area of ​​light by changing the structure of the lens surface.

[0005] In order to solve the above technical problems, the utility model discloses a new type of laser lens, including a first boss, a second boss extending upward from the top surface of the first boss, a frustum extending upward from the top surface of the second boss, a third boss extending upward from the top surface of the frustum, the outer peripheral side surface of the frustum and the top surface of the third boss are both formed with a brushed structure, and the roughness of the outer peripheral side surface of the frustum and the roughness of the top surface of the third boss are both Ra0.08~Ra0.12.

[0006] The roughness of the outer peripheral side surface of the frustum and the roughness of the top surface of the third boss are both Ra0.1.

[0007] A first through hole is formed in the middle of the first boss, a second through hole communicating with the first through hole is formed in the middle of the second boss, and a blind hole communicating with the second through hole is formed in the middle of the frustum.

[0008] The bottom of the blind hole is a curved surface structure.

[0009] Wherein, a plurality of positioning portions arranged at intervals along the circumferential direction extend inwardly from the hole wall of the first through hole.

[0010] The outer contour of the positioning portion is in the shape of a triangle, a rectangle, a circle, or a combination of two or more thereof.

[0011] The outer diameter of the second boss is smaller than that of the first boss, and the outer diameter of the third boss is smaller than that of the second boss.

[0012] Wherein, a cutout for positioning is formed on the outer peripheral side surface of the first boss.

[0013] Compared with the prior art, the embodiments of the utility model have the following beneficial effects: by setting the outer peripheral side surface of the frustum and the top surface of the third boss as light-emitting surfaces with a brushed structure, the light projected from the light-emitting surface of the lens after the surface brushing treatment becomes a delicate light beam, which can form diffuse reflection on the surface of the object, so that the laser electric eye can accurately identify every part of the object within the working angle, solving the problem of bright spots appearing in the center area of ​​the light in the past and improving the light efficiency.
