1. A five-dimensional laser scanning processing device, characterized in that, comprising: a laser emitting device, a turning optical path module (2), a deflection module (3), a beam expansion module (4), a plane scanning module (6) and a focusing module (5),
wherein said laser emitting device is arranged to emit a laser beam (1), said beam expansion module (4) is arranged to expand a beam radius of the laser beam (1), which subsequently enters said plane scanning module (6), said plane scanning module (6) comprises two reflective mirrors relatively positioned at a preset angle, through a continuous deflection of said two reflective mirrors, a scanning of the laser beam in an XY plane is achieved, the laser beam passes through said plane scanning module (6) and finally enters said focusing module (5) to converge into an ideal spot;
wherein the laser beam (1) enters an interior of a housing (7) along a horizontal direction through a light hole on the housing (7), and said turning optical path module (2), said deflection module (3), said beam expansion module (4), said focusing module (5), and said plane scanning module (6) are installed inside said housing (7);
said turning optical path module (2) comprises a lens housing and a reflective lens, wherein said reflective lens is placed at an angle of 45° relatively to the horizontally entering laser beam (1), said lens housing not only can install said reflective lens, but also has a function of adjusting said reflective lens by ±2°, so said lens after installation can reflect the light beam and make it vertically incident on said deflection module (3);
said deflection module (3) comprises a motor connecting plate (31), a moveable offset assembly (32), a guiding rail (33), a reflective mirror housing (34), a translation plate (35), and a control motor (36);
said motor connecting plate (31) is connected to said housing (7) through bolt holes and is fixed into position inside said housing (7), said guide rail (33) is fixedly installed on said motor connecting plate (31) in an X-axis direction through bearings and snap rings and is connected to said control motor (36) and said moveable offset assembly through threaded holes, a threaded hole at another end of said control motor (36) is connected to said translation plate (35), said reflective mirror housing (34) is installed on said translation plate (35), and said reflective mirror housing (34) is also installed on said guiding rail (33);
said reflective mirror housing (34) of said deflection module (3) is equipped with a reflective mirror housing reflective lens placed at an angle of 45°;
said deflection module (32) comprises a rotatable motor (321), a lens housing (322), an optical wedge snap ring (323), a first optical wedge (324), a second optical wedge (325), and an optical wedge snap ring (326);
said first optical wedge (324) and said second optical wedge (325) are arranged in parallel and are installed in said lens housing (322) through said optical wedge snap ring (322) and said optical wedge snap ring (236) respectively, wherein a wedge edge of said first optical wedge (324) is tangent to a wedge edge of said optical wedge snap ring (322), a wedge edge of said second optical wedge (325) is tangent to a wedge edge of said optical wedge snap ring (236), and said wedge edge of said first optical wedge (324) and said wedge edge of said second optical wedge (325) are parallel to each other; said lens housing (322) is fixed on said rotatable motor (321) and is coaxial with said rotatable motor (321), when said rotatable motor (321) rotates, said first optical wedge (324) and said second optical wedge (325) are driven to rotate, due to the characteristics of parallel double optical wedges, the passing laser beam (1) is offset along the X-axis.
