Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor lasers, and specifically to a high-power semiconductor laser light source. Background Art

[0002] Semiconductor lasers were successfully excited in 1962 and achieved continuous output at room temperature in 1970. Later, through improvement, double heterojunction lasers and laser diodes with stripe structures were developed. In terms of the basic structure, a semiconductor laser belongs to the P-N junction of a semiconductor, but a laser diode sandwiches the light-emitting layer (active layer) from both sides with a metal cladding, which is a "double heterojunction structure". Moreover, in a laser diode, the interface is used as an emission mirror (resonator). In terms of materials used, there are gallium (Ga), arsenic (As), indium (In), phosphorus (P), etc., which are widely used in optical fiber communication, optical discs, laser printers, laser scanners, laser pointers (laser pens), and are the lasers with the largest production volume. Laser light sources are commonly used in 3D printing devices, where ultraviolet light is projected onto photosensitive resin through a high-resolution DLP projector to cure the resin layer by layer.

[0003] In the prior art, a light source adjustment device for a laser 3D printer with the application number 202411416101.7 includes: a printer main body, a polarizing mirror, a laser, a moving stage, a light beam blocking part, and a protective channel. This light source adjustment device for a laser 3D printer effectively increases and improves the adjustment method of the laser beam and protects the propagation process of the laser beam, ensuring high-quality printing of the model while greatly improving the printing efficiency. However, it is difficult to meet the light source irradiation requirements at different heights and tilt angles, thus affecting the efficiency of light curing in 3D printing.

One end of the screw rod is drivingly connected to a second motor, so that the lifting slider can be driven by the lead screw to lift and adjust, thereby enabling the use heights of the first light source seat and the second light source seat to be adjusted, and further meeting the light irradiation requirements at different heights, which is beneficial to improving the efficiency of 3D printing irradiation curing.

[0007] Further, the middle part of the lifting slider is threadedly connected to the screw rod through a threaded hole, and two groups of screw rods and second motors are longitudinally arranged in parallel.

[0008] Further, the first light source seat is an annular light source seat, and the second light source seat is a semi-annular light source seat.

[0009] Further, the first light source seat and the second light source seat have the same radius, and a plurality of laser light sources are arranged at equal angles on the inner walls of the first light source seat and the second light source seat, so that the illumination uniformity of the first laser light source and the second laser light source is relatively strong.

[0010] Further, the gear set includes a driven gear arranged at one end of the connecting shaft, and a driving gear meshing with the driven gear is arranged at one end of the first motor, so that the connecting shaft can be driven by the first motor and the gear set to rotate forward and backward, thereby enabling the use angle of the second light source seat to be flipped and adjusted, and thus realizing multi-angle light use processing, and further improving the efficiency of 3D printing irradiation curing.

[0011] Further, the light source bracket is an inverted U-shaped bracket, and a mounting plate is arranged at the lower end of the light source bracket, which is convenient for installing and fixing the light source bracket.

[0023] Such as Figure 1 and Figure 2As shown in the figure, in order to improve the uniformity of illumination, the first light source base 7 is an annular light source base, and the second light source base 10 is a semi-annular light source base. The first light source base 7 and the second light source base 10 have the same radius, and a plurality of laser light sources are provided at equal angles on the inner walls of the first light source base 7 and the second light source base 10, so that the illumination uniformity of the first laser light source 13 and the second laser light source 12 is relatively strong.
