Abstract

The invention relates to the technical field of vibrating mirrors and specifically relates to a preview module and a dynamic focusing laser vibrating mirror so as to alleviate technical problems of large light loss and large occupied space in technologies of the prior art. The preview module comprises a first driving mechanism, a first transmission mechanism and a rocking arm, wherein a side face of the rocking arm is provided with a limiting groove, and a free end is provided with a red light emitting devices; the first transmission mechanism comprises a swing rod and a connecting piece, the swing rod is provided with a first installation hole and a second installation hole, the connecting piece is accommodated in the limiting groove after running through the first installation hole, an output shaft of the first driving mechanism extends into the second installation hole, the swing rod is driven by the first driving mechanism to rotate around the output shaft, rotation of the swing rod drives connecting piece to swing, and the rocking arm is driven to rise and fall via swinging of the connecting piece. The problem of light loss in the technologies of the prior art can be effectively prevented via the preview module and the dynamic focusing laser vibrating mirror disclosed in the invention, and installation space can be saved.

Description

technical field [0001] The invention relates to the technical field of vibrating mirrors, in particular to a preview module and a dynamic focusing laser vibrating mirror. Background technique [0002] Laser scanners are also called laser galvanometers, which consist of X-Y optical scanning heads, electronic drive amplifiers and optical mirrors. The signal provided by the computer controller drives the optical scanning head through the drive amplifier circuit, so as to control the deflection of the laser beam on the X-Y plane. [0003] Usually, a red light preview is required before laser scanning to improve the accuracy during the actual scanning process. However, the existing red light preview adopts the paraxial preset method, specifically: a lens is set on the laser light path, and the lens is at an angle of 45 degrees to the laser light path. The lens will reflect the incident red light and transmit the incident red light. laser. Although the preview mode set by the r...
