Description

Technical Field

[0001] This application relates to the field of lasers, and more specifically, to a laser device. Background Technology

[0002] Lasers are devices that generate laser light by amplifying it through stimulated emission, and they have important applications in many fields. In particular, the development of lasers has been rapid in recent years. They use laser materials as the working material, uniformly mixing a small amount of activating ions in a crystal or glass as the matrix material, using light as the excitation source, and then amplifying the light through an optical resonant cavity to ultimately achieve laser output. In applications such as marking objects, solid-state lasers have unique advantages.

[0003] Most existing lasers have complex structures, low internal space utilization, and are inconvenient to install. Utility Model Content

[0004] The purpose of this application is to provide a laser device to solve the problems of low internal space utilization and inconvenient installation of existing laser devices.

[0005] To solve the above problems, this application adopts the following technical solution:

[0006] This application provides a laser device, including:

[0007] The base is equipped with mounting holes and clearance grooves;

[0008] The upper housing has a receiving cavity, and the base covers the receiving cavity;

[0009] The light-emitting component is fixed to the mounting hole;

[0010] The cover plate is fixedly connected to the base;

[0011] A PCB board is located between the cover plate and the base, and the clearance groove accommodates a portion of the PCB board.

[0012] A cooling fan is fixed to the ends of the base and the upper housing.

[0013] Because the base has a recessed groove to accommodate part of the PCB board, and the base cover has a receiving cavity, the internal space of the laser equipment is utilized efficiently, resulting in a simpler, more compact structure that saves space. Furthermore, the base has mounting holes for easy fixing of the light-emitting components. The PCB board is located between the cover plate and the base, and the cover plate is fixedly connected to the base, making the installation of the laser equipment more convenient and quick.

[0014] Furthermore, the laser device includes a plano-convex mirror assembly, the upper housing is provided with a light-transmitting hole, the light-transmitting hole is connected to the receiving cavity, and the light-transmitting hole accommodates part of the plano-convex mirror assembly.

[0015] The plano-convex mirror assembly effectively focuses the laser, enabling the laser equipment to meet power output requirements and providing better directionality and focusing. At the same time, the light-transmitting aperture accommodates part of the plano-convex mirror assembly, improving space utilization.

[0016] Furthermore, the plano-convex mirror assembly includes a plano-convex lens and a plano-convex mirror mount, the plano-convex lens is installed inside the plano-convex mirror mount, and the light-transmitting hole accommodates a portion of the plano-convex mirror mount.

[0017] By accommodating a partial plano-convex lens mount in the light-transmitting aperture, the size of the device is reduced. The plano-convex lens is installed inside the plano-convex lens mount, which reduces laser scattering and attenuation and improves the focusing ability of the laser device.

[0018] Furthermore, the light-transmitting hole is a threaded hole, and the plano-convex mirror base is threadedly connected to the upper housing.

[0019] Because the plano-convex mirror mount is threaded to the upper housing, it improves the ease of assembly and maintenance of the laser equipment, and allows for convenient installation and disassembly.

[0020] Furthermore, the base is provided with a first fin and a second fin, the first fin being arranged in a horizontal direction and the second fin being arranged in a vertical direction.

[0021] By setting the first and second fins on the base, heat dissipation efficiency is improved, the internal temperature of the laser equipment is effectively reduced, and the operational stability of the laser is enhanced.

[0022] Furthermore, the base is provided with a positioning groove, and the PCB board is provided with a positioning boss, the positioning groove accommodating the positioning boss.

[0023] By setting positioning grooves on the base and positioning bosses on the PCB board, the assembly process of laser equipment becomes more precise and convenient.

[0024] Furthermore, the mounting holes are vertically arranged, so that the light-emitting component is located within the receiving cavity, reducing the space occupied by the laser equipment and improving space utilization.

[0025] Furthermore, the laser device includes a connection terminal, which is fixedly connected to the PCB board.

[0026] Because the laser equipment is equipped with connection terminals, the laser equipment can be better controlled through the connection terminals, thereby meeting the laser emission requirements.

[0027] Furthermore, the cover plate is provided with a clearance opening for accommodating the connection terminal.

[0028] Because the cover plate has a clearance opening, it is easier to assemble and disassemble the connection terminal and the cover plate, and maintenance is more efficient and faster.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Because the clearance groove of the base accommodates part of the PCB board, and the base covers the upper housing's receiving cavity, with the PCB board located between the cover plate and the base, the internal space utilization of the laser equipment is high, the structure is simple, more compact, and space-saving.

[0031] 2. The light-emitting components are fixed in the mounting holes, which facilitates the installation and removal of the light-emitting components, thus making the installation of laser equipment more convenient and quick. Attached Figure Description

[0039] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0041] It should be understood that the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings.

[0042] In the field of traditional high-power lasers, cooling measures are generally implemented to ensure normal operation and protect the equipment due to the heat generated during laser operation. Air cooling typically involves heat dissipation through ventilation holes on the laser surface. However, when heat is continuously generated, it is difficult to dissipate and remains inside the laser housing, leading to heat dissipation difficulties and affecting subsequent laser operation. A laser consists of a housing, a resonant cavity, and a light-emitting component. The light-emitting component emits the laser beam, and laser beam generation primarily requires adjustment of the total reflection mirror and output mirror. The resonant cavity provides optical feedback to generate continuous oscillations of stimulated emission, continuously enhancing the beam while limiting its direction and frequency, resulting in excellent directionality and monochromaticity of the output beam. Currently, most existing lasers have complex structures, low internal space utilization, and are inconvenient to install.

[0044] In view of this, such as Figures 1 to 5 As shown in the figure, this application provides a laser device, including a base 1, an upper housing 2, a light-emitting component 3, a cover plate 4, a PCB board 5, and a cooling fan 6. The base 1 is provided with a mounting hole 11 and a clearance groove 12. The upper housing 2 is provided with a receiving cavity 21. The base 1 covers the receiving cavity 21. The light-emitting component 3 is fixed to the mounting hole 11. The cover plate 4 is fixedly connected to the base 1. The PCB board 5 is located between the cover plate 4 and the base 1. The clearance groove 12 accommodates part of the PCB board 5. The cooling fan 6 is fixed to the ends of the base 1 and the upper housing 2.

[0045] Specifically, the assembled base 1 and upper housing 2 form a cuboid shape. A cooling fan 6 is fixed to the ends of the base 1 and upper housing 2; for example, the cooling fan 6 is located at the end furthest from the light-transmitting hole 22 of the laser device. The clearance groove 12 is a recess on one side, and the receiving cavity 21 is also a recess on one side. The opening direction of the clearance groove 12 is consistent with the opening direction of the recess in the receiving cavity 21. After the base 1 covers the receiving cavity 21, a resonant cavity is formed. The laser emitted by the light-emitting component 3 is reflected within the resonant cavity and finally emitted from the light-transmitting hole 22. The light-emitting component 3 is fixed at the mounting hole 11 of the base 1. The PCB board 5 is located between the cover plate 4 and the base 1. The cover plate 4 is fixedly connected to the base 1 to protect the PCB board 5. The clearance groove 12 accommodates part of the PCB board 5; for example, the clearance groove 12 accommodates some electronic components on the PCB board 5, reducing the space occupied by the laser device and improving space utilization. The cooling fan 6 effectively dissipates heat, preventing the laser device from overheating. Specifically, the mounting hole 11 is vertically positioned, and the light-emitting component 3 is partially located within the receiving cavity 21. One end of the light-emitting component 3 within the receiving cavity 21 is equipped with an inclined reflector. The axis of the light-transmitting hole 22 is horizontal, and the vertical laser emitted by the light-emitting component 3 is reflected and emitted horizontally from the light-transmitting hole 22. Because the light-emitting component 3 is partially located within the receiving cavity 21, the space occupied by the laser equipment is reduced, improving space utilization.

[0046] Because the clearance groove 12 of the base 1 accommodates part of the PCB board 5, and the base 1 is covered with a receiving cavity 21, the internal space of the laser equipment is utilized more efficiently, resulting in a simpler, more compact structure that saves space. Furthermore, the base 1 has mounting holes 11 for easy fixing of the light-emitting component 3. The PCB board 5 is located between the cover plate 4 and the base 1, and the cover plate 4 is fixedly connected to the base 1, making the installation of the laser equipment more convenient and quick.

[0047] In some embodiments, the laser device includes a plano-convex mirror assembly 7, and the upper housing 2 is provided with a light-transmitting hole 22, which communicates with the receiving cavity 21 and accommodates a portion of the plano-convex mirror assembly 7.

[0048] Specifically, in the laser device, the plano-convex mirror assembly 7 is used to guide and focus the laser. The upper housing 2 has a light-transmitting hole 22, which communicates with the receiving cavity 21, so that the laser beam exits from the receiving cavity 21 through the light-transmitting hole 22 and the plano-convex mirror assembly 7. The size of the light-transmitting hole 22 is matched and adapted to the size of the plano-convex mirror assembly 7. In the application scenarios of the laser device, for example, when marking an object, the plano-convex mirror assembly 7 can serve as a laser guiding and focusing element, guiding and focusing the laser beam onto the object for marking.

[0049] The plano-convex mirror assembly 7 effectively focuses the laser, enabling the laser equipment to meet power output requirements and providing better directionality and focusing. At the same time, the light-transmitting hole 22 accommodates part of the plano-convex mirror assembly 7, improving space utilization.

[0050] In some embodiments, the plano-convex lens assembly 7 includes a plano-convex lens 71 and a plano-convex lens mount 72, with the plano-convex lens 71 mounted inside the plano-convex lens mount 72, and the light-transmitting hole 22 accommodating a portion of the plano-convex lens mount 72.

[0051] Specifically, the light-transmitting aperture 22 accommodates the plano-convex lens mount 72, allowing the plano-convex lens 71 to be installed within it. This design is simple and easy to install. The laser beam exits through the light-transmitting aperture 22 and the plano-convex lens 71, ensuring the stability and accuracy of the laser beam during the marking process. By accommodating part of the plano-convex lens mount 72 within the light-transmitting aperture 22, the device size is reduced. The plano-convex lens 71, installed within the mount, reduces laser scattering and attenuation, improving the focusing ability of the laser device. Notably, the light-transmitting aperture 22 is a threaded hole, and the plano-convex lens mount 72 is threadedly connected to the upper housing 2. Regarding the maintenance and replacement of the laser device, the threaded connection between the plano-convex lens mount 72 and the upper housing 2 facilitates the replacement or maintenance of the plano-convex lens assembly 7. For example, the plano-convex lens assembly 7 can be unscrewed from the upper housing 2 before performing the necessary maintenance or replacement operations on the plano-convex lens 71. The threaded connection between the plano-convex lens mount 72 and the upper housing 2 enhances the ease of assembly and maintenance of the laser device, enabling convenient installation and disassembly.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the base 1 is provided with a first fin 13 and a second fin 14. The first fin 13 is arranged in the horizontal direction and the second fin 14 is arranged in the vertical direction.

[0053] Specifically, the base 1 is provided with multiple first fins 13 and multiple second fins 14. For example, multiple first fins 13 are provided on both sides of the base 1, and the multiple first fins 13 on each side are equally spaced. Multiple second fins 14 are located at both ends of the base 1, and the multiple second fins 14 communicate with the clearance groove 12. The multiple second fins 14 are also equally spaced. Since the cooling fan 6 is fixed to the ends of the base 1 and the upper housing 2, the cooling fan 6 can effectively cool the laser equipment through the first fins 13 and the second fins 14. In particular, the first fins 13 are arranged in a horizontal direction, and the second fins 14 are arranged in a vertical direction. By setting the first fins 13 and the second fins 14, the heat dissipation effect is further improved.

[0054] By setting the first fin 13 and the second fin 14 on the base 1, the heat dissipation efficiency is improved, the internal temperature of the laser equipment is effectively reduced, and the operating stability of the laser is improved.

[0055] In some embodiments, such as Figure 5 As shown, the base 1 is provided with a positioning groove 15, and the PCB board 5 is provided with a positioning boss 51. The positioning groove 15 accommodates the positioning boss 51.

[0056] Specifically, the base 1 serves as the basic structure of the device, supporting and fixing other components. To improve the structural stability of the base 1 and the accuracy of component installation, the base 1 is provided with positioning grooves 15. The positioning grooves 15 ensure that the PCB board 5 is accurately installed on the base 1, thereby improving the installation efficiency and stability of the entire device. For example, the PCB board 5 is provided with positioning bosses 51, which cooperate with the positioning grooves 15 on the base 1 to ensure the accurate position of the PCB board 5 in the device. In particular, the positioning bosses 51 are stepped, with stepped positioning bosses 51 on both sides of the PCB board 5, and positioning grooves 15 on both sides of the base 1 near the clearance groove 12. When installing the PCB board 5, the positioning bosses 51 and positioning grooves 15 enable quick loading and unloading of the base 1 and the PCB board 5.

[0057] By setting a positioning groove 15 on the base 1 and a positioning boss 51 on the PCB board 5, the assembly process of the laser equipment is made more precise and convenient.

[0058] In some embodiments, the laser device includes a connection terminal 8, which is fixedly connected to the PCB board 5.

[0059] Specifically, in the laser equipment, the connecting terminal 8 serves as a control connection, used to connect the circuitry on the PCB board 5 to other external devices or power supplies. By fixing the connecting terminal 8 to the PCB board 5, the stability and reliability of the laser equipment connection can be ensured. For example, the connecting terminal 8 adopts a pluggable structure, facilitating quick installation and disassembly, improving the installation efficiency and convenience of the laser equipment, and also helping to reduce the equipment failure rate. To ensure a reliable connection between the connecting terminal 8 and the PCB board 5, welding or other fixing methods can be used to fix the connecting terminal 8 to the PCB board 5. In particular, the cover plate 4 has a clearance opening 41 for accommodating the connecting terminal 8. For example, the clearance opening 41 is a rectangular groove, and the connecting terminal 8 is cuboid in shape; the rectangular groove fits the connecting terminal 8. Because the cover plate 4 has a clearance opening, the installation and removal of the connecting terminal 8 from the cover plate 4 is simpler, and maintenance is more efficient and faster.

[0060] The connection terminal 8 is located near the cooling fan 6 and is fixed to the PCB board 5. Data transmission is achieved through the connection terminal 8, enabling the operation of components on the PCB board 5 and thus controlling the operation of the laser equipment. Because the laser equipment has the connection terminal 8, it can be better controlled, thereby meeting the laser emission requirements.
