Description

Technical Field

[0001] The utility model relates to the technical field of laser racks, in particular to a semiconductor laser working rack. Background Art

[0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working media. The working principle of semiconductor lasers is to use the state of particle number inversion in the PN junction of semiconductor materials to achieve light amplification and emission. When current passes through the semiconductor, electrons and holes recombine in the junction area, releasing energy to generate photons. These photons reflect back and forth in the crystal, further stimulating the recombination of other electron-hole pairs, generating more photons of the same frequency, phase, and direction, forming laser output. Semiconductor lasers are characterized by small size and long life, and can be pumped by simply injecting current. Due to their unique advantages, semiconductor lasers are widely used in fiber-optic communications, data storage, laser printing, CD reading, medical equipment, and scientific research.

[0003] Semiconductor lasers are usually installed in a fixed manner during laser processing to ensure stable operation and long-term use. Lasers installed in this manner cannot be adjusted in position, have many usage restrictions, and are not convenient for production use. Utility Model Content

[0017] See also Figure 1-2 The utility model provides a technical solution: a semiconductor laser working frame, comprising a base 1, a moving base 2 and a laser mounting plate 3, wherein the base 1 is in a strip-shaped structure as a whole, and a guide rail 11 is arranged on the base 1, and the guide rail 11 is in the same length direction as the base 1; a driving seat 21 is arranged at the lower part of the moving base 2, and the driving seat 21 is matched and clamped on the guide rail 11 and slides along the length direction of the guide rail 11; the laser mounting plate 3 is arranged on the upper part of the moving base 2, and a screw barrel 23 is arranged on the upper part of the moving base 2, and a stud 31 is arranged at the lower part of the laser mounting plate 3, and the stud 31 and the screw barrel 23 are butted against each other; the screw barrel 23 is driven by a servo motor embedded in the moving base 2, and a semiconductor laser is mounted on the laser mounting plate 3.

[0018] Furthermore, the guide rail 11 is arranged at the middle position of the upper surface of the base 1, and a toothed belt 13 is arranged on the guide rail 11; a first card slot is arranged at the lower part of the driving seat 21, and the first card slot is engaged with the toothed belt 13; and a driving gear is embedded in the driving seat 21, and the driving gear is transmitted from the first card slot and meshes with the toothed belt 13; the driving gear is driven by a driving motor embedded in the moving seat 2.

[0019] Furthermore, mutually parallel limiting belts 12 are arranged on both sides of the guide rail 11, and a limiting block 22 is correspondingly arranged at the lower part of the movable seat 2. A second slot is arranged at the lower part of the limiting block 22, and the limiting block 22 is mutually engaged with the limiting belt 12 through the second slot.

[0020] Furthermore, limiting grooves 14 are recessed inwardly on both sides of the limiting belt 12, and limiting plates 25 are correspondingly arranged at the groove edges of the second slots, and the limiting plates 25 are mutually engaged with the limiting grooves 14; an arc-shaped rolling groove 15 is arranged on the upper surface of the limiting belt 12, and balls are embedded in the limiting blocks 22, and the balls are correspondingly arranged in the rolling grooves 15.

[0022] Working principle: In actual use, holes are punched on the laser mounting plate 3 according to the installed laser model, so that the semiconductor laser is fixed to the laser mounting plate 3 by bolts. The servo motor drives the screw barrel 23 to rotate, so that it engages with the stud 31, and then the stud 31 can shrink in the screw barrel 23, so as to adjust the height of the laser mounting plate 3; when the laser mounting plate 3 moves up and down, the guide rods 32 at the four corners are docked in the guide barrel 24, so as to ensure the stability of the laser mounting plate 3 during the up and down movement.
