Embodiment Construction
[0041] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] like figure 1 and figure 2 As shown, the laser beam control device provided by the present invention includes a galvanometer group consisting of an X-axis galvanometer 2 and a Y-axis galvanometer 3, a focusing field lens 4 (that is, an F-Theta focusing lens) and a laser turret box 5 , the laser turret box 5 is placed behind the galvanometer group and the focusing field lens 4; the laser beam 1 passes through the X-axis galvanometer 2 and the Y-axis galvanometer 3 to change direction, passes through the focusing field lens 4, and enters the laser turret box 5.
[0043] The laser turning head box 5 is a closed light-tight casing, including an optical device accommodation area (such as figure 2 and image 3 cuboid area shown) and working area (such as figure 2 and image 3 Shown setting is cone a...

The invention discloses a laser beam control device. The laser beam control device comprises a galvanometer group; a plane mirror, wherein the plane mirror and the optical axis of the laser beam output by the galvanometer group form an angle alpha, alpha being larger than 0 degree and smaller than 90 degrees, and the plane mirror is used for carrying out total reflection on the laser beam and allowing light rays with other wavelengths to penetrate through; and optical imaging equipment arranged on one side, far away from the galvanometer group, of the plane mirror, wherein the optical imagingequipment and the optical axis of the laser beam reflected by the plane mirror are coaxially arranged. According to the laser beam control device, the plane mirror is arranged at the downstream of thegalvanometer group (and the focusing lens) to totally reflect the laser beam, so that the scanning coordinates of the galvanometer group are subjected to simple mirror image transposition, and the laser scanning range and the focusing plane are kept at the same time; and therefore, coaxial observation and full-view-field observation of the optical imaging equipment are realized during laser scanning operation. The invention further provides a control method for the laser beam control device.
Description
technical field [0001] The invention relates to a laser beam control device and a control method for the above laser beam control device, belonging to the technical field of laser processing. Background technique [0002] Laser scanning galvanometers are widely used in industrial laser processing and medical laser fields. In the process of using the laser beam controlled by the laser scanning galvanometer to perform operations, it is necessary to set up a CCD camera to observe the field of view and assist visual positioning, so as to observe and adjust the laser. [0003] In existing laser equipment, the CCD camera is usually arranged upstream of the laser scanning galvanometer. For example, the utility model of CN201721134U discloses a near-wavelength coaxial positioning laser marking system, including a laser emitting laser, a beam expander, a CCD image sensor, a mirror, a scanning galvanometer, and emitting illumination light adjacent to the laser wavelength The illumin...
