Abstract
Description
Technical Field
[0001] This application relates to the field of lasers, and more specifically, to a solid-state laser. Background Technology
[0002] A laser is a device that generates light by amplifying it through stimulated emission, and it has important applications in many fields. The pump source and gain medium of a laser generate heat during operation; if this heat is not dissipated in time, it will affect the device's lifespan and performance. Since the power density of the emitted laser is relatively low, it cannot be used for engraving. It needs to be focused by a focusing lens to fix the surface to be engraved at the focal point before engraving can proceed.
[0003] Existing lasers require a focusing ruler for focusing when adjusting the focal length. The focusing operation is complicated and it is difficult to keep the laser heat dissipation in a good way. Therefore, it needs to be improved. Utility Model Content
[0004] The purpose of this application is to provide a solid-state laser to solve the problems of complicated focusing operations and difficulty in heat dissipation in existing lasers.
[0005] To solve the above problems, this application adopts the following technical solution:
[0006] This application provides a solid-state laser, comprising:
[0007] The base is equipped with multiple primary heat sinks;
[0008] The upper shell is provided with a first rotating hole, a limiting hole and multiple fins, and a receiving groove is formed between two adjacent fins;
[0009] The focusing rod is provided with a second rotating hole, and the focusing rod is located in the receiving groove;
[0010] A rotating shaft passes through the first rotating hole and the second rotating hole;
[0011] A limiting post is inserted through the limiting hole;
[0012] A cooling fan is located at the end of the base and the upper housing, and the cooling fan is used to dissipate heat from the first heat sink and the fins.
[0013] The focus lever and rotating shaft make focusing easier and improve operational efficiency. The base has multiple primary heat sinks, and the cooling fan is located at the ends of the base and upper housing, improving the laser's heat dissipation performance and thus balancing laser cooling with focus adjustment.
[0014] Furthermore, the upper housing is provided with two limiting holes, which are located on both sides of the first rotating hole.
[0015] Since the two limiting holes are located on both sides of the first rotating hole, the rotation range of the focusing rod is effectively limited.
[0016] Furthermore, the limiting hole is a waist hole, which improves the limiting effect when the focusing rod abuts against the limiting post inside the limiting hole.
[0017] Furthermore, the focusing rod is bent.
[0018] When operating the bent focusing rod, it requires less effort, is easier to operate, and improves the operating effect.
[0019] Furthermore, the focusing rod has a toggle part located at one end away from the second rotating hole, making it more convenient and efficient to rotate the focusing rod by operating the toggle part.
[0020] Furthermore, when the focusing rod is located in the receiving groove, the actuating part protrudes from the upper housing.
[0021] When it is necessary to move the focus lever, the lever protrudes from the upper housing, allowing for better operation and avoiding the need to remove the focus lever from the receiving slot.
[0022] Furthermore, the base is provided with a plurality of second heat sinks, which are aligned with the first heat sink.
[0023] By combining the second heat sink with the first heat sink, the heat dissipation effect of the solid-state laser is effectively improved.
[0024] Furthermore, multiple second heat sinks are arranged at equal intervals.
[0025] The multiple second heat sinks are spaced at equal intervals, which enhances the internal thermal conductivity of the solid-state laser and improves the heat dissipation effect.
[0026] Furthermore, the solid-state laser also includes a protective mesh, which is fixedly connected to the cooling fan.
[0027] The protective net effectively protects the cooling fan, thereby extending its lifespan and reducing the risk of damage.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. The focus lever and rotating shaft make focusing more convenient, the structure is simple, the focus is easy to adjust, and the operating efficiency is improved.
[0030] 2. Since the base is equipped with multiple first heat sinks and the cooling fan is located at the end of the base and the upper shell, the cooling fan dissipates heat from the first heat sinks and fins, improving the heat dissipation performance of the solid-state laser. This ensures the heat dissipation effect of the laser and facilitates the adjustment of the focal length. Attached Figure Description

[0042] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0043] 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.

[0045] 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. Most commonly, water cooling systems are used for heat dissipation, offering better cooling performance. However, water cooling systems are bulky, occupying significant space and increasing production costs. Air cooling utilizes ventilation holes on the laser surface. When heat is continuously generated, it is difficult to dissipate and remains inside the laser housing, hindering heat dissipation and affecting subsequent laser operation. Furthermore, the power density of the laser beam immediately after emission is low, insufficient for engraving requirements. It needs to be focused by a focusing lens to fix the surface to be engraved at the focal point before engraving can begin. Conventional simple laser focusing requires a focusing ruler; the material to be processed is placed on the worktable, and the focusing ruler is placed on the surface of the material. This focusing operation is cumbersome and makes it difficult to simultaneously address laser heat dissipation. Therefore, improvements are needed.
[0046] Figure 1 An exploded view of a solid-state laser provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a solid-state laser provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of an upper shell provided in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of an upper housing and a focusing rod provided in an embodiment of this application, wherein the focusing rod abuts against a limiting post; Figure 5 This is a schematic diagram of the structure of a base provided in an embodiment of this application; Figure 6 This is a schematic diagram of a focusing rod provided in an embodiment of this application.
[0047] In view of this, such as Figures 1 to 6 As shown, this application provides a solid-state laser, including a base 1, an upper housing 2, a focusing rod 3, a rotating shaft 4, a limiting post 5, and a cooling fan 6. The base 1 has multiple first heat sinks 11; the upper housing 2 has a first rotating hole 21, a limiting hole 22, and multiple fins 23, with a receiving groove 2A formed between adjacent fins 23; the focusing rod 3 has a second rotating hole 31 and is located within the receiving groove 2A; the rotating shaft 4 passes through the first rotating hole 21 and the second rotating hole 31; the limiting post 5 passes through the limiting hole 22; and the cooling fan 6 is located at the ends of the base 1 and the upper housing 2, and is used to dissipate heat from the first heat sinks 11 and the fins 23.
[0048] Specifically, the base 1 is provided with multiple first heat sinks 11, and the upper housing 2 is provided with multiple fins 23. A heat conduction channel is formed between two adjacent first heat sinks 11 and between two adjacent fins 23. The cooling fan 6 is located at the ends of the base 1 and the upper housing 2. When the cooling fan 6 is running, it dissipates heat from the solid-state laser through the heat conduction channels, effectively dissipating the heat generated by the pump source and gain medium to maintain the stable operating temperature of the laser, thereby achieving a cooling effect. The upper housing 2 is provided with a first rotating hole 21 and a limiting hole 22 to facilitate the installation of the rotating shaft 4 and the limiting post 5, respectively, ensuring the precise positioning of the focusing rod 3. Since the rotating shaft 4 passes through the first rotating hole 21 and the second rotating hole 31, the focusing rod 3 can rotate flexibly within the receiving groove 2A, thereby meeting the requirements for adjusting the focal length. For example, after the focus adjustment is completed, the focus lever 3 is moved, causing it to rotate and retract into the receiving groove 2A. The focus lever 3 then abuts against the limiting post 5, indicating that the focus lever 3 has rotated to the retracted position, thus preventing excessive rotation of the focus lever 3 and damage to the focus lever 3 or the upper housing 2. At the same time, since the limiting post 5 passes through the limiting hole 22, it limits the rotation range of the focus lever 3.
[0049] In actual operation, users can adjust the focal length by rotating the focusing rod 3, simplifying the focusing process. To further improve operational convenience and heat dissipation, the speed of the cooling fan 6 can be controlled to achieve real-time adjustment of the heat dissipation effect. For example, the speed of the cooling fan 6 can be automatically adjusted by an algorithm to optimize the heat dissipation effect based on the working state of the laser and the ambient temperature. Specifically, the upper housing 2 is provided with two limiting holes 22, which are located on both sides of the first rotating hole 21. For example, the two limiting holes 22 are arranged in a straight line with the first rotating hole 21, and the two limiting holes 22 are located on both sides of the first rotating hole 21, with equal spacing between them. Each limiting hole 22 contains a limiting post 5. After the focal length is adjusted, the focusing rod 3 is moved, causing it to rotate and retract into the receiving groove 2A, and the focusing rod 3 abuts against a limiting post 5. When the focus needs to be adjusted, the focusing rod 3 is turned in the opposite direction, causing it to rotate out of the receiving groove 2A and abut against another limiting post 5. This prevents the focusing rod 3 from retracting into the receiving groove 2A on the other side when rotated in the opposite direction. Since the two limiting holes 22 are located on both sides of the first rotating hole 21, the rotation range of the focusing rod 3 is effectively limited.
[0050] The focus rod 3 and the rotating shaft 4 make it easier to adjust the focus and improve the operating efficiency. Since the base 1 is equipped with multiple first heat sinks 11 and the cooling fan 6 is located at the ends of the base 1 and the upper shell 2, the cooling fan 6 dissipates heat from the first heat sinks 11 and the fins 23, improving the heat dissipation performance of the solid-state laser. This ensures the heat dissipation effect of the laser and facilitates the adjustment of the focus.
[0051] In some embodiments, such as Figure 3 As shown, the limiting hole 22 is a waist-shaped hole, and the outline of the limiting post 5 is adapted to the limiting hole 22. The focusing rod 3 abuts against the limiting post 5 inside the limiting hole 22 to improve the limiting effect. For example, when the side of the limiting post 5 abuts against the focusing rod 3, it is in surface contact, which increases the contact area between the limiting post 5 and the focusing rod 3. At the same time, it can also ensure that when the focusing rod 3 retracts into the receiving groove 2A, part of its outline is parallel to the fin 23.
[0052] In some embodiments, the focusing rod 3 is bent. For example, when the focusing rod 3 retracts into the receiving groove 2A, the other end of the focusing rod 3 bends towards the laser emission direction, thereby reducing the space occupied by the solid-state laser and reducing the risk of accidental contact. Operating the bent focusing rod 3 requires less effort, is easier to operate, and improves operational efficiency. In particular, the focusing rod 3 has a toggle part 32 located at the end away from the second rotating hole 31, making it more convenient and efficient to rotate the focusing rod 3 by operating the toggle part 32. See also Figure 2 When the focusing rod 3 is located in the receiving groove 2A, the actuating part 32 protrudes from the upper housing 2. When it is necessary to actuate the focusing rod 3, since the actuating part 32 protrudes from the upper housing 2, the actuating part 32 can be operated more easily, avoiding the need to remove the focusing rod 3 from the receiving groove 2A.
[0053] In some embodiments, such as Figure 5 As shown, the base 1 is provided with multiple second heat sinks 12, each second heat sink 12 being paired with each first heat sink 11, and the second heat sink 12 and the first heat sink 11 are aligned. When the cooling fan 6 is running, the alignment of the second heat sink 12 and the first heat sink 11 forms a heat conduction channel, improving the heat dissipation effect of the solid-state laser. In particular, the multiple second heat sinks 12 are arranged at equal intervals. Due to the equal intervals of the multiple second heat sinks 12, the internal thermal conductivity of the solid-state laser is further enhanced, improving the heat dissipation effect.
[0054] In some embodiments, the solid-state laser also includes a protective mesh 7, which is fixedly connected to a cooling fan 6. Specifically, the cooling fan 6 is located between the protective mesh 7 and the base 1. The protective mesh 7 effectively protects the cooling fan 6, thereby improving its service life and reducing the risk of damage.
[0055] For a better understanding of the solid-state laser in the embodiments of the present application, the implementation principle thereof will be described below. That is: when focusing is required, an acting force is applied to the focusing rod 3 to pull out the focusing rod 3 from the accommodation groove 2A to adjust the position of the solid-state laser. For example, turn the slide rail matching the solid-state laser, or set fixing holes on the solid-state laser and set long holes on the installation device of the solid-state laser. After the position is adjusted, it is fixed by bolts. After focusing is completed, a reverse acting force is applied to the focusing rod 3 to accommodate the focusing rod 3 in the accommodation groove 2A to complete the positioning of the laser. During this period, the two limiting columns 5 respectively limit the focusing rod 3 to control the rotation range of the focusing rod 3 and reduce the risk of excessive rotation of the focusing rod 3.
[0056] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present application.
