Description

Technical Field

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

[0002] A laser is a device that generates light 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.

[0003] Existing lasers often improve heat dissipation efficiency by adjusting the fan structure, but this is not effective in dissipating heat from the laser components and cannot meet their heat dissipation requirements. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide a laser that solves the problem that existing lasers are unable to effectively dissipate heat from their components and thus fail to meet the heat dissipation requirements of the components.

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

[0006] This application provides a laser, comprising:

[0007] The housing has a first mounting hole;

[0008] The PCB board is equipped with a second mounting hole;

[0009] A control chip is located between the PCB board and the housing, and the control chip is fixed to the PCB board;

[0010] The column has a fixing hole, and its two ends abut against the PCB board and the housing respectively. The first mounting hole accommodates part of the column.

[0011] A fastener is sequentially inserted into the second mounting hole and the fixing hole;

[0012] A cooling fan is located at the end of the housing and is fixedly connected to the housing.

[0013] By setting up pillars between the PCB board and the housing, heat dissipation of the control chip and PCB board is effectively achieved, improving heat dissipation efficiency; the heat dissipation effect can be further improved by setting up cooling fans.

[0014] Furthermore, the laser is provided with a connection terminal, which is fixedly connected to the PCB board.

[0015] The fixed connection between the connector and the PCB board reduces signal interference and improves the stability and accuracy of laser signal transmission. As part of the external interface, the connector facilitates easy connection between the laser and external cables or plugs.

[0016] Furthermore, the laser is provided with two connection terminals, which are respectively fixedly disposed on both sides of the PCB board.

[0017] The laser has two connection terminals, which can meet different connection requirements and improve the application flexibility of the laser.

[0018] Furthermore, the connection terminal is located at the end of the PCB board near the cooling fan, thereby shortening the heat transfer path, removing heat more quickly, improving local heat dissipation efficiency, and enhancing the reliability of the electrical connection.

[0019] Furthermore, the column is provided with an abutment portion, which is located at one end of the column away from the fixing hole.

[0020] Because the column has an abutment part, it is convenient for the installation between the column and the shell, thus improving assembly efficiency.

[0021] Furthermore, the abutting part is provided with an annular abutting surface. The abutting part is located in the first mounting hole, and the annular abutting surface contacts the top surface of the housing, thereby improving the abutting effect between the column and the housing, reducing the risk of displacement, and improving reliability.

[0022] Furthermore, the fixing hole is a threaded hole, and the fixing member is threadedly connected to the column.

[0023] Because the fastener is threadedly connected to the column, the column can be quickly installed and disassembled, improving loading and unloading efficiency and facilitating laser maintenance.

[0024] Furthermore, the laser has a plurality of columns and a plurality of fasteners, the columns and the fasteners being arranged in pairs.

[0025] Multiple columns and fasteners ensure that the PCB board is more securely fixed to the housing, thus improving the stability of the PCB board.

[0026] Furthermore, mounting portions are provided on both sides of the housing, and the first mounting hole is located in the mounting portion, thereby better fixing the housing, enhancing stability, and thus improving the reliability and durability of the laser.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up pillars between the PCB board and the housing, the PCB board is suspended, which effectively dissipates heat from the control chip and the PCB board, improving heat dissipation efficiency.

[0029] 2. The cooling fan is located at the end of the housing. The cooling fan at the end further improves the heat dissipation effect of the laser and improves the air cooling efficiency. Attached Figure Description

[0041] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0042] 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.

[0044] 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 for heat dissipation. However, when heat is continuously generated, it is difficult to dissipate and remains inside the laser housing, leading to cooling difficulties. Furthermore, existing lasers often improve heat dissipation efficiency by adjusting the fan structure, but this is insufficient for effectively cooling the laser components and meeting their cooling requirements. Therefore, improvements are needed.

[0046] In view of this, such as Figures 1 to 6 As shown in the figure, this application provides a laser, including a housing 1, a PCB board 2, a control chip 3, a column 4, a fixing member 5, and a cooling fan 6. The housing 1 is provided with a first mounting hole 11, the PCB board 2 is provided with a second mounting hole 21, the control chip 3 is located between the PCB board 2 and the housing 1 and is fixed to the PCB board 2, the column 4 is provided with a fixing hole 41, and the two ends of the column 4 abut against the PCB board 2 and the housing 1 respectively. The first mounting hole 11 accommodates a portion of the column 4, the fixing member 5 is sequentially inserted through the second mounting hole 21 and the fixing hole 41, and the cooling fan 6 is located at the end of the housing 1 and is fixedly connected to the housing 1.

[0047] Specifically, the PCB board 2 and the housing 1 are tightly connected by a column 4 and a fixing member 5, with both ends of the column 4 abutting against the PCB board 2 and the housing 1 respectively. The fixing member 5 provides reinforcement, ensuring a stable connection between the PCB board 2 and the housing 1. The control chip 3 is fixed on the PCB board 2 and located between the PCB board 2 and the housing 1. It should be noted that other components, such as capacitors and resistors, are also installed on the side of the PCB board 2 facing the housing 1. Because of the column 4 between the PCB board 2 and the housing 1, the PCB board 2 is suspended, forming a heat dissipation channel between the PCB board 2 and the housing 1, improving heat dissipation efficiency. The cooling fan 6 is located at the end of the housing 1, directly blowing cool air into the housing 1 and expelling hot air from inside, thereby effectively reducing the internal temperature of the housing 1.

[0048] For example, the cooling fan 6 is located at the end of the housing 1, the PCB board 2 covers the housing 1 and the cooling fan 6, the end of the housing 1 is provided with multiple threaded holes, the cooling fan 6 is fixed to one end of the housing 1 by screws, the other end of the housing 1 is the laser emission port, after the light-emitting component of the laser emits laser light, it resonates inside the housing 1, and finally emits it from the laser emission port.

[0049] It should be noted that, due to the pillars set between the PCB board 2 and the housing 1, the PCB board 2 is suspended, which effectively dissipates heat from the control chip 3 and the PCB board 2, improving heat dissipation efficiency. At the same time, the cooling fan 6 is located at the end of the housing 1, which further improves the heat dissipation effect of the laser and improves the air cooling efficiency.

[0050] In some embodiments, the laser is provided with a connection terminal 7, which is fixedly connected to the PCB board 2. Specifically, the connection terminal 7 is used for electrical connection with an external power supply or other electronic equipment. The connection terminal 7 can be fixed to the PCB board 2 by crimping or other reliable connection methods to ensure the stability of the electrical connection. When installing the PCB board 2, a pre-reserved mounting position for the connection terminal 7 is provided on the PCB board 2, and corresponding positioning holes are designed. The size and shape of the connection terminal 7 match the mounting position on the PCB board 2.

[0051] It should be noted that in different application scenarios, the connection terminal 7 can be modified and varied according to the actual situation. For example, the number, shape, size, and material of the connection terminal 7 can be changed, or other different fixed connection methods can be adopted, all without departing from the spirit and principles of this application. The fixed connection between the connection terminal 7 and the PCB board 2 reduces signal interference and improves the stability and accuracy of laser signal transmission. As part of the external interface, the connection terminal 7 facilitates convenient docking between the laser and external cables or plugs.

[0052] Specifically, the laser has two connection terminals 7, which are fixedly mounted on both sides of the PCB board 2. The presence of two connection terminals 7 allows the laser to meet different connection requirements, thus enhancing its application flexibility.

[0053] In some embodiments, the connection terminal 7 is located at the end of the PCB board 2 near the cooling fan 6. Specifically, the PCB board 2 is used to support electronic components and the control chip 3, and the connection terminal 7 is fixed at the end of the PCB board near the cooling fan 6. Since the connection terminal 7 is located at the end of the PCB board 2 near the cooling fan 6, rather than at the end near the laser emission port, the impact on the laser operation is reduced when the connection terminal 7 is plugged in and unplugged from other connecting lines, and the ease of plugging and unplugging is improved. After other electronic components are soldered or mounted onto the PCB board, the assembled electronic device is tested to ensure that it can work normally, and the connection terminal and cooling fan are checked to ensure that they are working properly. By placing the connection terminal at the end of the PCB board near the cooling fan, it is easier to perform overall layout and routing, improves the integration and reliability of the electronic device, and at the same time, shortens the heat transfer path, removes heat more quickly, improves local heat dissipation efficiency, and improves the reliability of electrical connections.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, the column 4 is provided with an abutment part 42, which is located at the end of the column 4 away from the fixing hole 41.

[0055] Specifically, the column 4 is provided with an abutment portion 42 for abutting against the housing 1. The abutment portion 42 is located at the end of the column 4 away from the fixing hole 41, so that it can be easily connected and positioned with the housing 1 while providing support. The column 4 is used to provide support, and the cross-sectional shape of the column 4 can be circular, square, rectangular, or other shapes. The fixing hole 41 is provided on the column 4 for fixing the column 4 to the PCB board 2 by bolts, screws, or other fasteners. Figure 5 As shown, the abutment portion 42 is a protruding boss, and its shape and size are adapted to the first mounting hole 11. The abutment portion 42 is abutted against the housing 1 to be abutted. For example, the stepped surface of the abutment portion 42 can be brought into close contact with the surface of another housing 1, thereby achieving the positioning and connection of the two components. The abutment portion 42 is cylindrical, and the housing 1 has a cylindrical first mounting hole 11. Since the column 4 has the abutment portion 42, it is beneficial to install the column 4 and the housing 1, improving assembly efficiency. In particular, the abutment portion 42 has an annular abutment surface 421. The abutment portion 42 is located in the first mounting hole, and the annular abutment surface 421 contacts the top surface of the housing 1, thereby improving the abutment effect between the column 4 and the housing 1, reducing the risk of displacement, and improving reliability.

[0056] In some embodiments, the fixing hole 41 is a threaded hole, and the fixing member 5 is threadedly connected to the column 4. Specifically, the fixing hole 41 is provided on the column 4, and the fixing hole 41 is a threaded hole, through which the fixing member 5 is threadedly connected. The fixing member 5 fixes the column 4 to the PCB board 2, and the fixing member 5 can be a screw, stud, or other threaded fastener. The length, diameter (or cross-sectional dimensions), and material of the column 4 are determined according to the required support height and strength. The fixing hole 41 is opened on the column 4, and the fixing hole 41 is a threaded hole. The size of the threaded hole (including diameter and pitch) should be adapted to the specifications of the selected fixing member 5. For example, a suitable fixing member 5 is selected according to the size of the threaded hole of the column 4, while considering the length of the fixing member 5 to ensure that it can penetrate the PCB board 2 that needs to be fixed. When assembling the column 4 and the fixing member 5, the fixing member 5 is passed through the second mounting hole 21 of the PCB board 2, and the threaded part of the fixing member 5 is screwed into the fixing hole 41 on the column 4. The fixing member 5 is then tightened using a wrench or other tools to ensure a tight connection between the column 4 and the PCB board 2. Because the fixing member 5 is threadedly connected to the column 4, the column 4 can be quickly installed and disassembled, improving assembly and disassembly efficiency and facilitating laser maintenance. Specifically, the laser has multiple columns 4 and multiple fixing members 5, arranged in pairs. For example, the laser has four columns 4, four fixing members 5, and the PCB board 2 has four second mounting holes 21 distributed around the perimeter of the PCB board 2 in a two-row, two-column arrangement. The housing 1 has four first mounting holes 11 at corresponding positions. Through the multiple columns 4 and multiple fixing members 5, the PCB board 2 is more securely fixed to the housing 1, improving the stability of the PCB board 2.

[0057] In some embodiments, mounting portions 12 are provided on both sides of the housing 1, and first mounting holes 11 are located on the mounting portions 12. For example, the mounting portions 12 are located on both sides of the housing 1, and each side of the housing 1 is provided with two first mounting holes 11. A column 4 is fixed at each first mounting hole 11. Through multiple columns 4 and mounting portions 12, the housing 1 can be better fixed, enhancing stability and thereby improving the reliability and durability of the laser.

[0058] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this 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 make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed in this application.
