[0044] Please refer to Figure 1 and Figure 2 , the first embodiment of the present utility model provides a laser gun head assembly, including a gun head body 1, a fixed seat 2, and a composite tube 3. A clamping groove 11 is provided on the side of the gun head body 1. The fixed seat 2 is detachably installed on the clamping groove 11. The composite tube 3 is fixed to the side of the gun head body 1 by being installed in the fixed seat 2. The composite tube 3 includes at least two wires 31 / pipes 32. At least one wire 31 / pipe 32 connection end is led out through the fixed seat 2.

[0045] It should be noted that the gun head body 1 is applied in the field of laser cutting. By irradiating the material to be cut with a laser beam having a high power density, through the interaction between the laser and the material, the material is rapidly melted, vaporized, or ablated, thereby achieving precise cutting. In addition, the gun head body 1 can also be applied in fields such as laser welding and cleaning, using a high-energy laser beam as a heat source for efficient and precise welding or quickly evaporating or peeling off impurities, contaminants, or coatings on the surface of an object.

[0046] It can be understood that the fixed seat 2 is detachably installed on the gun head body 1. The user can flexibly disassemble the fixed seat 2 and set the position of the fixed seat 2 according to needs to adapt to different requirements. When the composite tube 3 shakes, it is easy to drive the wires 31 / pipes 32 to shake or disconnect. Therefore, the fixed seat 2 plays a role in fixing the composite tube 3 to avoid pulling the wires 31 / pipes 32 and damaging the pipe 32 and affecting the communication function of the wire 31.

[0047] Furthermore, the fixed seat 2 has opposite ends. One end is provided with a first connection hole 21, and the other end is provided with at least one second connection hole 22. The first connection hole 21 communicates with the second connection hole 22. A quick connector 23 is provided in one of the second connection holes 22. When the composite tube 3 is connected to the fixed seat 2, it is connected at the first connection hole 21, and the wires 31 / pipes 32 are led out through the second connection hole 22 for connecting the wires 31 / pipes 32 respectively.

[0048] In this embodiment, the composite tube 3 includes a wire 31 and a pipe 32. The connection ends of the wire 31 and the pipe 32 are respectively led out from one second connection hole 22.

[0049] Further, a quick connector 23 is provided at the connection end of the pipeline 32 where it extends from the fixed seat 2. The quick connector 23 is set as a rigid connector. While facilitating the disassembly and installation of the pipeline 32, the soft pipeline 32 is protected from extrusion through the quick connector 23, avoiding damage to the pipeline 32 and affecting gas transmission.

[0050] Further, the fixed seat 2 further includes a buckle 24. The buckle 24 is located at the end of the fixed seat 2 away from the light-emitting section 12. The fixed seat 2 is detachably mounted on the gun head body 1 through the buckle 24. The buckle 24 makes the fixed seat 2 more firmly mounted on the outer surface of the gun head body 1, preventing slippage.

[0051] Please refer to Figure 5 and Figure 6 As shown in, the gun head body 1 includes a housing 19 and a connected light-emitting section 12 and a transmitting section 13. The light-emitting section 12 includes a reflecting mirror 121, a reflecting mirror adjusting component 122, a focusing lens component 123, and a protective lens component 124 arranged in sequence inside the housing 19. An optical outlet 131 is provided at the end of the transmitting section 13 away from the light-emitting section 12. The reflecting mirror 121 is located at one end away from the optical outlet 131, and the reflecting mirror adjusting component 122 is connected to the reflecting mirror 121.

[0052] It can be understood that the reflecting mirror 121 and the reflecting mirror adjusting component 122 play a role in precisely adjusting the propagation direction and spatial distribution of the laser beam entering the light-emitting section 12; the focusing lens component 123 is mainly used for focusing the beam; the protective lens component 124 in the gun head body 1 is mainly used to protect other optical elements from pollution, damage, or the direct impact of laser radiation; after the laser beam enters the laser light-emitting section 12 from the laser output head 41, it passes through the reflecting mirror 121, the focusing lens component 123, and the protective lens component 124 in sequence, and then is output from the optical outlet 131. The combination of the reflecting mirror 121, the reflecting mirror adjusting component 122, the focusing lens component 123, and the protective lens component 124 ensures that the laser beam can be precisely emitted from the optical outlet 131 to complete welding and cutting work.

[0053] Further, the reflecting mirror adjusting component 122 includes screw holes 1221 and setscrews 1222. A number of screw holes 1221 are provided on the reflecting mirror adjusting component 122. By respectively installing setscrews 1222 and screws in the screw holes 1221, the movement direction control of the reflecting mirror 121 in two opposite directions is realized to precisely adjust the direction of the reflecting mirror 121.

[0054] Further, the end of the setscrew 1222 is set as a ball head structure. By rotating the setscrew 1222, the inclination angle of the reflecting mirror 121 is changed, thereby realizing the adjustment of the laser beam direction.

[0055] Further, the laser passes through the light-emitting section 12 and then passes through the transmitting section 13, and is output from the optical outlet 131 at the end of the transmitting section 13.

[0056] Preferably, the protective mirror assembly 124 is provided with two protective mirrors, and one of the protective mirrors close to the light outlet 131 is detachably installed in the light-emitting section 12. The protective mirror on the side close to the light outlet 131 is liable to be contaminated and damaged by impurities and debris during the laser cutting process. Therefore, the detachable design facilitates the replacement of the protective mirror on the side close to the light outlet 131, so as to better protect the other protective mirror and other components in the light-emitting section 12 by replacing this protective mirror, and extend the service life of each lens in the light-emitting section 12.

[0057] As a feasible embodiment, a detachable adjusting ring 132 is sleeved on the end of the emitting section 13 close to the protective mirror assembly 124. By flexibly setting the number and length of the adjusting rings 132, the focus of the gun head body 1 is adjusted, so as to reserve an adjusting means for cutting materials of different thicknesses, and also reserve an adjusting means for focus offset, improving the accuracy and stability of the operator's operation of holding the gun head body 1.

[0058] Furthermore, an elastic band is arranged at one end of the gun head body 1 close to the laser output head 41. When the user holds the gun head body 1 for operation, the stability of the gun head body 1 is improved by sleeving the elastic band on the wrist, avoiding affecting the user's stability due to the heavy weight of the gun head body 1.

[0059] Furthermore, a high-pressure gas passage 125 is opened in the gun head body 1. The inlet of the high-pressure gas passage 125 is located on the side of the light-emitting section 12 away from the emitting section 13, and the outlet of the high-pressure gas passage 125 is located at the connection between the emitting section 13 and the light-emitting section 12 and communicates with the emitting section 13.

[0060] Specifically, a slidable lens group 110 is arranged inside the gun head body 1 on the side of the light-emitting section 12 away from the emitting section 13 for collimating the laser.

[0061] Furthermore, the lens group 110 can be flexibly composed of multiple convex lenses according to different applicable scenarios and environments to meet the personalized needs of the gun head body 1.

[0062] In this embodiment, the lens group 110 includes three lenses.

[0063] Furthermore, an adjusting hole 191 is arranged on the housing 19 corresponding to the lens group 110. The user can adjust the position of the lens group 110 from the outside through the adjusting hole 191, so that the lens group 110 can work more precisely.

[0064] Furthermore, after the position of the lens group 110 is fixed, fixing parts are arranged in the fixing holes 192 on both sides of the adjusting hole 191, so that the gun head body 1 can work stably, avoiding the sliding of the lens group 110 from affecting the laser accuracy.

[0065] Optionally, the fixing member in the fixing hole 192 is a screw, a set screw or a hard member. After the position of the lens group 110 is determined, the fixing member facilitates fixing the lens group 110 to the inside of the gun head body 1, ensuring the stability of the operation of the lens group 110.

[0066] Please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 , a second embodiment of the present invention provides a laser gun head assembly, including the laser gun head assembly provided in the above first embodiment, further including a laser emitting device 4 and a gas source box 5. A first connection seat 14 and a second connection seat 15 which are electrically connected are arranged on the gun head body 1. The laser emitting device 4 includes an output line 43. The output line 43 includes an electric control line 431. The electric control line 431 is electrically connected to the first connection seat 14. Both ends of the pipeline 32 are respectively connected to the gun head body 1 and the gas source box 5. Both ends of the wire 31 are respectively connected to the second connection seat 15 and the gas source box 5.

[0067] It can be understood that the electric control line 431 is used to supply power to the gun head body 1 and transmit signals. The laser emitting device 4 and the gas source box 5 are respectively electrically connected to the gun head body 1 through the first connection seat 14 and the second connection seat 15 to achieve communication.

[0068] Furthermore, the laser emitting device 4 includes a laser output head 41 and a laser generator 42. The laser output head 41 is connected to one end of the laser gun head body 1 far from the light outlet 131. The laser generator 42 is connected to the laser output head 41 and the gun head body 1 through the output line 43 to complete the output of the laser from the gun head body 1 to complete welding and cutting operations.

[0069] Furthermore, a first connection structure 18 is arranged on the gun head body 1. A card slot 241 is arranged at the end of the buckle 24. A second connection structure 411 and an operation section 412 are correspondingly arranged on the laser output head 41. On the operation section 412, a locking member 4121 protruding outward from the second connection structure 411 is arranged. When the gun head body 1 is connected to the laser output head 41, the first connection structure 18 and the second connection structure 411 are connected, and the locking member 4121 is clamped with the card slot 241. The first connection structure 18 and the second connection structure 411 are a matching cylindrical structure. The first connection structure 18 is hollow and its cross-section is larger than the cross-section of the second connection structure 411.

[0070] It can be understood that the second connection structure 411 is connected inside the first connection structure 18. The first connection structure 18 provides guidance for the gun head body 1 during the connection process, improving the accuracy of the connection path of the laser output head 41 and protecting the laser output head 41, thereby extending the service life of the laser output head 41. The surface of the second connection structure 411 is smooth, facilitating cooperation with the first connection structure 18 during the connection process and reducing the resistance between the two. The card slot 241 cooperates with the locking member 4121. After the second connection structure 411 and the first connection structure 18 are installed in cooperation, the stability of the second connection structure 411 and the safety of the laser output head 41 during operation are further improved, avoiding losses caused by deviations in laser emission.

[0071] It should be noted that please refer to Figure 3 、 Figure 4 and Figure 5 , a lens 4122 is arranged inside the operation section 412. When the laser outputs from the laser output head 41, it first passes through the lens 4122. Only the laser adapted to the lens 4122 is the collimated light that can achieve the required focusing effect. After the laser passing through the lens 4122 enters the gun head body 1, the lens group 110 performs collimation again and inputs the collimated laser into the light output section 12.

[0072] Please refer to Figure 3 、 Figure 6 and Figure 7 , the laser generator 42 plays a role in generating laser. The output line 43 also includes a laser output line. The two ends of the laser output line are respectively connected to the laser output head 41 and the laser generator 42, and the laser generated in the laser generator 42 is transmitted to the laser output head 41.

[0073] It can be understood that the gas source box 5 is used to provide the auxiliary gas required during the laser processing and is transmitted to the gun head body 1 through the pipeline 32, playing a role in protecting the laser working process and improving the working efficiency.

[0074] Furthermore, the connection end of the electric control wire 431 is detachably connected to the first connection seat 14. The structure in which the connection end of the electric control wire 431 is detachably connected to the first connection seat 14 enables the laser output head 41 and the gun head body 1 to be easily connected and detached at any time, facilitating user use.

[0075] As a feasible embodiment, the connection end of the electric control wire 431 is set as a magnetic head, and the corresponding first connection seat 14 is set as a magnetic seat. The magnetic head is magnetically connected to the magnetic seat, facilitating connection and disassembly at any time, and reducing the connection interruption caused by the pulling of the electric control wire 431 when separating the laser output head 41 and the gun head body 1.

[0076] Further, a second connection seat 15 is provided on the gun head body 1. The gas source box 5 further includes a solenoid valve. The composite tube 3 further includes a wire 31. One end of the wire 31 is connected to the solenoid valve, and the other end is detachably connected to the second connection seat 15. After the wire 31 is connected to the second connection seat 15, the gun head body 1 can control the solenoid valve through the wire 31.

[0077] Preferably, the connection end of the wire 31 and the second connection seat 15 are magnetically connected, which is convenient for the wire 31 to be connected and detached at any time, and avoids damage to the wire 31 caused by pulling during use.

[0078] Further, the composite tube 3 is provided with a magic tape wrapping the pipeline 32 and the wire 31, which is convenient for opening the magic tape at any time to adjust the composite tube 3.

[0079] Further, the gas source box 5 includes a gas storage device. The connection end of the pipeline 32 is connected to one end of the light-emitting section 12 of the gun head body 1 away from the light outlet 131, so that the gas can pass through the light-emitting section 12 and be output from the light outlet 131. The protective gas is stored in the gas storage device. The gas improves the cutting speed and quality through measures such as assisting combustion, preventing oxidation and pollution, and cleaning the cut seam, and ensures that the gun head body 1 can stably complete laser cutting and other work.

[0080] Optionally, the gas storage device can be a gas cylinder or a gas pump.

[0081] Preferably, to reduce the volume, facilitate portability and be used for outdoor operations, the gas is stored in the gas pump. When the gas pump is installed in the gas source box 5, it has a smaller volume and a larger gas capacity, reducing the burden on outdoor operation personnel and facilitating operation.

[0082] Please refer to Figure 1 、 Figure 5 and Figure 8 , a high-pressure gas channel 125 is opened in the gun head body 1. The connection end of the pipeline 32 is connected to the inlet of the high-pressure gas channel 125, so that the protective gas enters the high-pressure gas channel 125. The gas and the laser that has passed through the protective mirror assembly 124 in the light-emitting section 12 together pass through the emission section 13 along the high-pressure gas channel 125 and are emitted from the light outlet 131. During the laser cutting process, the protective gas plays a role in assisting combustion and the like, enabling the laser output by the gun head body 1 to better complete the cutting work.

[0083] Optionally, the gas can be controlled by a manual control valve or a solenoid valve connected to the gas storage device. Controlling the gas on and off through the manual control valve can improve the flexibility of the cooperation between the gas storage device and the gun head body 1. During the working process, the gas can be controlled at any time through the manual control valve, which is simple to operate and can improve safety, avoiding safety accidents caused by improper operation or misoperation. Controlling the gas on and off through the solenoid valve can achieve precise regulation and control of the gas flow rate, reduce operation delay, and improve the overall response speed of the system.
