[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0032] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0033] Before processing, the blue light semiconductor laser needs to adjust the relative distance between the laser and the workpiece. Since the relative distance between different workpieces and the laser is different, the relative distance between the laser and the workpiece needs to be readjusted when processing different workpieces. The current method of adjusting the relative distance between the laser and the workpiece is relatively cumbersome and easily affects the processing efficiency.
[0034] In view of this, the utility model provides a blue light semiconductor laser, such as Figure 1 As shown, Figure 1 The structure of a blue light semiconductor laser is shown in FIG.
[0035] The utility model provides a blue light semiconductor laser, comprising: a housing 10, a laser core and a focus plate 11;
[0036] The housing 10 is a hollow structure with openings at both ends;
[0037] The laser core is installed in the housing 10;
[0038] like Figure 2 As shown, Figure 2 The structure of the housing is shown in the figure. The outer wall of the housing 10 is provided with a focus groove 14 adapted to the structure of the focus plate 11;
[0039] The focus plate 11 is slidably connected to the focus groove 14. The focus plate 11 can be slidably extended to the outside of the shell 10 along the light emitting direction of the laser core relative to the focus groove 14, so as to limit the relative distance between the light emitting point of the laser core and the workpiece.
[0040] It should be noted that the laser core is used to emit a laser beam focused on the surface of the workpiece outside the shell 10. Since the focal length of the laser core is fixed and the mechanical structure between the laser core and the shell 10 is fixed, it is necessary to adjust the relative distance between the laser and the workpiece, taking the light emitting point of the laser core as a reference, such as Figure 3 As shown, Figure 3 The diagram illustrates the structure of a blue light semiconductor laser in which a focus plate 11 extends out of a housing 10. In this embodiment, the focus plate 11 is slidably connected to a focus groove 14. The focus plate 11 can be slidably extended to the outside of the housing 10 along the light emitting direction of the laser core relative to the focus groove 14, thereby limiting the relative distance between the light emitting point of the laser core and the workpiece. The extension length of the focus plate 11 can be determined based on the focal length of the laser core, so that the laser focus emitted by the laser core falls on the surface of the workpiece, thereby facilitating the adjustment of the relative distance between the light emitting point of the laser core and the workpiece, thereby improving the processing efficiency.
[0041] It should also be noted that a large amount of heat will be generated during the processing of the laser core. Figure 2 As shown, fins 17 are provided around the inner wall of the shell 10 of this embodiment, and the fins 17 are installed on the outside of the laser core, so that the heat generated by the laser core during the processing can be quickly transferred to the fins 17, which can play a good heat dissipation role.
[0042] In one feasible manner, in order to blow away the smoke and dust generated during the processing of the laser core, the blue light semiconductor laser provided in this embodiment also includes a fan, which is installed inside the housing 10, and the air outlet direction of the fan is set toward the laser core.
[0043] In order to increase the efficiency of smoke removal, the blue light semiconductor laser provided in this embodiment also includes a wind collecting hood 13, which is a hollow structure with openings at both ends, and the axial cross-section of the wind collecting hood 13 is an isosceles trapezoidal structure; the wind collecting hood 13 is installed on the outer wall of one end of the shell 10 and is arranged relative to the air outlet direction of the fan.
[0044] The air collecting cover 13 is detachably connected to the shell 10 .
[0045] Exemplarily, the air collecting cover 13 is connected to the shell 10 by magnet attraction, so as to facilitate assembly and disassembly.
[0046] Magnets are arranged at the four corners of the wind collecting cover 13 corresponding to the shell 10 , and the wind collecting cover 13 is connected to the shell 10 by magnet attraction.
[0047] Among them, Figure 2 As shown, the focus plate 11 and the focus groove 14 are connected by attraction through a magnet 16, so as to facilitate disassembly and assembly.
[0048] In a specific embodiment, the blue light semiconductor laser provided in this embodiment further includes an adjustment rod 12, such as Figure 4 As shown, Figure 4 The structure of the adjusting rod is shown in the figure. The adjusting rod 12 is sequentially provided at the adjusting handle 121, the gear 122 and the bearing connecting part 123 from top to bottom;
[0049] like Figure 5 As shown, Figure 5 The structure of the focus plate is shown in the figure. The focus plate 11 is provided with a strip-shaped slot 112 along the axial direction. A rack 111 is provided on the inner wall of one side of the strip-shaped slot 112 along the axial direction.
[0050] like Figure 2 As shown, the focusing groove 14 is provided with a bearing 15 adapted to the structure of the bearing connection portion 123 on the wall surface of the strip-shaped slot 112;
[0051] The bearing connection portion 123 passes through the strip-shaped slot hole 112 and is rotatably connected to the bearing 15 , and the gear 122 is meshingly connected to the rack 111 .
[0052] In order to improve the adjustment accuracy, the fixed focus plate 11 is provided with a scale bar along the axial direction, and the user can adjust the actual distance between the laser and the surface of the workpiece according to the needs, which is convenient and quick to operate.
[0053] It should be noted that, in this embodiment, by twisting the adjustment handle 121 of the adjustment rod 12, the gear 122 and the rack 111 are meshed with each other, and under the action of the rotational connection between the bearing connection part 123 and the bearing 15, the focusing plate 11 can be raised and lowered to slide relative to the focusing groove 14 to adjust the actual distance between the laser and the surface of the workpiece, and the operation is convenient and quick.
[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
