[0047] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] See also Figure 1 and Figure 2 The first embodiment of the present invention provides a laser output head 1, which is used for detachably connecting with a remote laser emitting head 21 or a handheld laser emitting head 22. The laser output head 1 includes a connected operating section 12 and a laser output section 11. The laser output section 11 is provided with a first cylindrical structure 111 with a smooth surface. A locking piece 121 is provided at one end of the outer periphery of the operating section 12 close to the laser output section 11, and the locking piece 121 is protruding relative to the first cylindrical structure 111.

[0049] It can be understood that the first cylindrical structure 111 is used to be connected to the remote laser transmitter 21 or the handheld laser transmitter 22. The surface of the first cylindrical structure 111 is set to a smooth surface, which helps to better connect the first cylindrical structure 111 with the remote laser transmitter 21 or the handheld laser transmitter 22, avoid the surface of the laser output head 1 hindering the connection and disassembly process, reduce the loss of the laser output head 1, and extend the service life; after the first cylindrical structure 111 is connected to the handheld laser transmitter 22 or the remote laser transmitter 21, the installation stability is improved by clamping with the locking piece 121, and the laser output head 1 is prevented from falling off during use, affecting the accuracy of laser transmission between different devices; by flexibly connecting the handheld laser transmitter 22 or the remote laser transmitter 21 at the connection end of the laser output head 1, the laser output head 1 is used in different scenarios and purposes, the adaptability and flexibility of the laser output head 1 are improved, and it is avoided to set an additional connection structure when connecting devices for different purposes, reduce costs, and facilitate user operation.

[0050] See 2 and Figure 4 The end surface of the first cylindrical structure 111 away from the stopper 121 is provided with a trigger 1111, a mounting hole 1112 and a protective valve core 1115. The trigger 1111 protrudes from the end surface of the first cylindrical structure 111 and is in transmission connection with the protective valve core 1115. When the trigger 1111 is pushed toward the end close to the output head body by an external force, the protective valve core 1115 is driven to rotate, so that the mounting hole 1112 can be connected to the outside world through the end surface of the first cylindrical structure 111. After the outside world is connected to the mounting hole 1112 through the trigger 1111, the laser can be output through the mounting hole 1112, and the laser can flexibly play different roles after being processed by the corresponding equipment.

[0051] Furthermore, the first tubular structure 111 also includes an elastic reset member 1114. After the trigger member 1111 is not affected by external force, the trigger member 1111 and the protective shell 1113 are restored to a natural state under the drive of the elastic reset member 1114, and the mounting hole 1112 is restored to a closed state, thereby avoiding the laser from being connected to other devices and reducing the loss of laser in the laser output head 1.

[0052] Furthermore, a launching hole 11151 is opened on the protection valve core 1115 , and a trigger ear 11152 is set at the end, a trigger groove 11111 is started on the trigger member 1111 , and the trigger member 1111 is connected to the protection valve core 1115 through the trigger ear 11152 and the trigger groove 11111 . When the trigger member 1111 is in a natural state, the emission hole 11151 is not connected to the mounting hole 1112, and the protective valve core 1115 blocks the mounting hole 1112, thereby preventing laser output when the laser output head 1 is not working, thereby extending the service life of the laser output head 1; when the end of the trigger member 1111 exposed to the first tubular structure 111 is thrusted, it moves inward to push the trigger ear 11152, and after the trigger ear 11152 is triggered, it slides in the trigger groove 11111, driving the protective valve core 1115 to rotate, and rotating the emission hole 11151 to a position connected to the mounting hole 1112, at which time the laser is emitted through the emission hole 11151 and the mounting hole 1112 and enters the laser emitting device 2.

[0053] Furthermore, the first tubular structure 111 also includes a protective shell 1113, which covers the protective valve core 1115, the elastic reset member 1114 and a part of the trigger member 1111. The end of the trigger member 1111 is exposed from the protective shell 1113, so that the laser can be emitted by pushing the end of the trigger member 1111 during installation. At the same time, the protective shell 1113 protects the internal components of the first tubular structure 111, thereby extending the service life of the laser output head 1.

[0054] In summary, please combine Figure 1 , Figure 2 and Figure 4 The first embodiment of the present invention provides a working process and principle of a laser output head 1 as follows:

[0055] When the laser output head 1 is connected to the corresponding remote laser emitting head 21 or handheld laser emitting head 22, the first cylindrical structure 111 is first connected to the corresponding device, and the trigger member 1111 drives the protective valve core 1115 to rotate after being subjected to thrust, and then the laser can be emitted from the emitting hole 11151 and the mounting hole 1112 by connecting the mounting hole 1112 with the emitting hole 11151; after the laser output section 11 is connected, the laser output head 1 is firmly installed through the locking member 121 on the operating section 12 to avoid problems such as the laser output head 1 slipping off or poor laser output accuracy during use; when disassembling the laser output head 1, the connection between the locking member 121 and the laser emitting device 2 is first released, and then the fixation of the first cylindrical structure 111 is released. After the trigger member 1111 is not subjected to external force, the trigger member 1111 and the protective valve core 1115 are driven by the elastic reset member 1114 to return to the position of blocking the laser output.

[0056] See also Figure 2 , Figure 3 and Figure 7 A second embodiment of the present invention provides a laser output device, comprising the laser output head 1 provided in the first embodiment, and also comprising a laser emitting device 2, wherein the laser emitting device 2 is a remote laser emitting head 21 and / or a handheld laser emitting head 22, wherein a first connecting structure 211 and a first slot 212 are provided on the remote laser emitting head 21, and a second connecting structure 228 and a second slot 229 are provided on the handheld laser emitting head 22, wherein after the first tubular structure 111 is connected to the first connecting structure 211 / the second connecting structure 228, the stopper 121 is engaged with the first slot 212 / the second slot 229; the first connecting structure 211 and the second connecting structure 228 are tubular structures matched with the first tubular structure 111, wherein the first connecting structure 211 and the second connecting structure 228 are hollow and have a cross section larger than the cross section of the first tubular structure 111, and the first slot 212 and the second slot 229 are respectively provided at the openings of the first connecting structure 211 and the second connecting structure 228.

[0057] It can be understood that the first cylindrical structure 111 is connected to the inside of the first connecting structure 211 and the second connecting structure 228. The first connecting structure 211 and the second connecting structure 228 provide guidance for the first cylindrical structure 111 during the connection process between the laser output head 1 and the laser emitting device 2, thereby improving the accuracy of the connection path of the laser output head 1, protecting the laser output head 1, and extending the service life of the laser output head 1; the surface of the first cylindrical structure 111 is smooth, and it is easy to cooperate with the first connecting structure 211 / the second connecting structure 228 during the connection process, thereby reducing the resistance between the two; the first clamping groove 212 / the second clamping groove 229 cooperates with the stopping member 121, and after the first cylindrical structure 111 and the first connecting structure 211 / the second connecting structure 228 are installed in cooperation, the stability of the first cylindrical structure 111 and the safety of the operation of the laser output head 1 are further improved, thereby avoiding losses caused by deviations in laser emission.

[0058] As a feasible implementation method, the remote laser transmitter 21 is connected to the laser output head 1 to focus, collimate, and shape the laser output by the laser output head 1, and is used in fields such as laser obstacle removal, and is convenient to disassemble when not in use; the handheld laser transmitter 22 is connected to the laser output head 1 to adjust the accuracy of laser emission, and is applied to the field of laser cutting, using a high-power density laser beam to irradiate the material to be cut, and through the interaction between the laser and the material, the material is quickly melted, vaporized or ablated, thereby achieving precise cutting, and is disconnected when not in use, so as to facilitate the flexible connection of other types of equipment to the laser output head 1; in addition, the handheld laser transmitter 22 can also be used in fields such as laser welding and cleaning, using a high-energy laser beam as a heat source for efficient and precise welding or for rapid evaporation or peeling of impurities, pollutants or coatings on the surface of an object.

[0059] Specifically, the remote laser transmitter 21 can be connected to the gimbal 5, the gimbal 5 is placed on an external plane, and the remote laser transmitter 21 is installed on the gimbal 5. The height and direction of the remote laser transmitter 21 can be flexibly adjusted through the gimbal 5, and operation and aiming errors caused by the user holding the remote laser transmitter 21 can be avoided, the operation is simplified to ensure the accuracy of laser emission, and the working efficiency of the remote laser transmitter 21 is improved.

[0060] Furthermore, the pan-tilt head 5 includes a bracket 51, which is supported on an external plane. By adjusting the height of the bracket 51, the height of the pan-tilt head 5 and the remote laser transmitter 21 can be flexibly adjusted, so that the remote laser transmitter 21 can better adapt to the external environment and improve the accuracy of laser emission.

[0061] Furthermore, the remote laser emitting head 21 is also provided with a cover 213 at the end of the first connecting structure 211. When the remote laser emitting head 21 is not connected to the laser output head 1, the cover 213 covers the first connecting structure 211 to prevent dust and other debris from entering and protect the internal structure of the first connecting structure 211.

[0062] See also Figure 5 , Figure 6 and Figure 7 The handheld laser emitting head 22 also includes a light emitting section 221, and the end of the second connecting structure 228 away from the second card slot 229 is connected to the light emitting section 221. The second connecting structure 228 plays a role of stable connection with the laser output head 1, so that the laser can be accurately transmitted between the laser output head 1 and the light emitting end 221. The laser emitted by the laser output head 1 is processed by the light emitting section 221 and then output, and the angle between the light emitting section 221 and the second connecting structure 228 is greater than or equal to 90°.

[0063] Furthermore, a slidable lens group 226 is provided on one side of the light emitting section 221 close to the second connecting structure 228, for collimating the laser entering the lens group 226, and an adjustment groove 227 is correspondingly provided on the outer wall of the light emitting section 221, through which the position of the lens group 226 can be adjusted inside the handheld laser transmitting head 22.

[0064] Furthermore, after the position of the lens group 226 is fixed, by setting fixing parts in the fixing holes 2210 on both sides of the adjustment groove 227, the handheld laser emitting head 22 can work stably to prevent the lens group 226 from sliding and affecting the laser accuracy.

[0065] It should be noted that a lens 122 is arranged inside the operating section 12. When the laser is output from the laser output head 1, it first passes through the lens 122. The laser adapted to the lens 122 is the collimated light that can achieve the desired focusing effect. After the laser passes through the lens 122 and enters the handheld laser transmitting head 22, the lens group 226 is collimated again to input the collimated laser into the light output section 221.

[0066] Furthermore, the lens group 226 can be flexibly composed of multiple convex lenses according to different application scenarios and environments to meet the personalized needs of the handheld laser transmitter head 22.

[0067] In this embodiment, the lens group 226 includes three lenses.

[0068] Optionally, the fixing member in the fixing hole 2210 is a screw, a jackscrew or a hard member. After the position of the lens group 226 is determined, the fixing member facilitates fixing the lens group 226 inside the handheld laser emitting head 22 to ensure the working stability of the lens group 226.

[0069] Furthermore, the light emitting section 221 includes a reflector 2211, a reflector adjustment assembly 2212, a focusing lens assembly 2213, a protective lens assembly 2214 and a light outlet 2215. The light outlet 2215 is located at the end of the light emitting section 221 away from the second connecting structure 228.

[0070] 2211 is located at one end close to the light outlet 2215 , the protective mirror assembly 2214 is located at one side close to the light outlet 2215 , and the focusing mirror assembly 2213 is located between the reflecting mirror 2211 and the protective mirror assembly 2214 .

[0071] It can be understood that the reflector 2211 and the reflector adjustment assembly 2212 play the role of accurately adjusting the propagation direction and spatial distribution of the laser light beam entering the light output section; the focusing mirror assembly 2213 is mainly used to focus the light beam; the protective mirror assembly 2214 is mainly used in the handheld laser emission head 22 to protect other optical components from pollution, damage or direct influence of laser radiation; after the laser beam enters the laser light output section 221 from the laser output head 1, it passes through the reflector 2211, the focusing mirror assembly 2213 and the protective mirror assembly 2214 in sequence, and is output from the light output port 2215. The combination of the reflector 2211, the reflector adjustment assembly 2212, the focusing mirror assembly 2213 and the protective mirror assembly 2214 ensures that the laser beam can be accurately emitted from the light output port 2215 to complete welding and cutting work.

[0072] Furthermore, the reflector adjustment component 2212 includes screw holes 22121 and top screws 22122. A plurality of screw holes 22121 are provided on the reflector adjustment component 2212. By respectively installing the top screws 22122 and screws in the screw holes 22121, the movement direction of the reflector 2211 in two opposite directions can be controlled to accurately adjust the direction of the reflector 2211.

[0073] Furthermore, the end of the top screw 22122 is configured as a ball head structure, and the inclination angle of the reflector 2211 is changed by rotating the top screw 22122, thereby achieving adjustment of the direction of the laser beam.

[0074] See also Figure 1 , Figure 2 and Figure 5 The light emitting section 221 also includes an emission section 2216 . The laser passes through the protection mirror assembly 2214 and then passes through the emission section 2216 , and is output from the light outlet 2215 at the end of the emission section 2216 .

[0075] Preferably, two protective mirrors are arranged in the light emitting section 221, and the protective mirror near the light outlet 2215 is detachably installed in the light emitting section 221. The protective mirror near the light outlet 2215 is susceptible to contamination and damage by impurities and debris during the laser cutting process. Therefore, the detachable design facilitates the replacement of the protective mirror near the light outlet 2215, so that by replacing the protective mirror, the other protective mirror and other components in the light emitting section 221 can be better protected, thereby extending the service life of each lens inside the light emitting section 221.

[0076] As a feasible embodiment, a detachable adjustment ring 2217 is provided at the end of the emitting section 2216 near the protective mirror assembly 2214. By flexibly setting the number and length of the adjustment rings 2217, the focus of the handheld laser transmitter 22 can be adjusted to reserve adjustment means for cutting materials of different thicknesses. At the same time, adjustment means are also reserved for focus offset, thereby improving the accuracy and stability of the operator's operation of the handheld laser transmitter 22.

[0077] Furthermore, an elastic band is provided at one end of the handheld laser transmitter head 22 near the laser output head 1. When the user holds the laser transmitter head 22 for operation, the stability of the handheld laser transmitter head 22 is improved by putting the elastic band on the wrist, thereby avoiding the influence of the heavy weight of the handheld laser transmitter head 22 on the user's stability.

[0078] In summary, please combine Figures 1 to 5 The working process and principle of the laser output device provided by the second embodiment of the present invention are as follows:

[0079] When the laser output head 1 is connected to the laser emitting device 2, the first cylindrical structure 111 is installed inside the first connecting structure 211 / the second connecting structure 228, and the locking member 121 is correspondingly engaged with the first slot 212 / the second slot 229 to make the installation of the two more stable. Under the action of external force, the trigger member 1111 connects the mounting hole 1112 and the outside world, so that the laser can accurately enter the remote laser emitting head 21 or the handheld laser emitting head 22.

[0080] See also Figure 1 , Figure 8 and Fig. 9The third embodiment of the present invention provides a laser generating device, including the laser output device provided by the above-mentioned second embodiment, and also including a laser generator 3 and an air source box 4. The laser generator 3 includes a main unit 31 and an output line 32. The air source box 4 includes a composite tube 41. The composite tube 41 includes an air outlet pipe 411. The main unit 31 is connected to the laser output head 1 through the output line 32. The air source box 4 is connected to the handheld laser transmitting head 22 through the air outlet pipe 411.

[0081] It can be understood that the main unit 31 generates laser light and transmits the laser light to the laser output head 1 through the output line 32. The laser light can enter the laser emitting device 2 through the laser output head 1. The gas source box 4 is used to provide the auxiliary gas required in the laser processing process, and transmits it to the laser emitting device 2 through the gas outlet pipe 411, thereby protecting the laser working process and improving work efficiency.

[0082] Furthermore, the gas outlet pipe 411 is a hose to facilitate flexible flow of gas.

[0083] Furthermore, the output line 32 includes a first electric control line 321 and a laser transmission line. The laser transmission line is used to transmit the laser generated by the host 31 to the laser output head 1 , and the first electric control line 321 is used to supply power to the laser emitting device 2 and transmit signals.

[0084] Furthermore, the first electric control line connection end 3211 is exposed on the laser output head 1, and the laser emitting device 2 is provided with a first connection seat 23, and the first electric control line 321 connection end is detachably connected to the first connection seat 23. The structure of the detachable connection between the first electric control line 321 connection end and the first connection seat 23 makes it easy to connect and disconnect the laser output head 1 and the laser emitting device 2 at any time, which is convenient for users to use.

[0085] As a feasible embodiment, the connection end of the first electric control line 321 is set as a magnetic head, and the corresponding first connecting seat 23 is set as a magnetic seat. The magnetic head is magnetically connected to the magnetic seat, which is convenient for connection and disassembly at any time, and when separating the laser output head 1 and the laser emitting device 2, it reduces the damage of the output line 32 caused by pulling the first electric control line 321.

[0086] Specifically, a first circuit board is arranged inside the remote laser emitting head 21, and the first electric control line 321 is electrically connected to the first circuit board by connecting to the first connecting socket 23 located on the remote laser emitting head 21, and communicates with the remote laser emitting head 21. After the electrical signal of opening and closing the laser is obtained by the remote laser emitting head 21 and sent to the first circuit board, the first circuit board converts the electrical signal into a signal for controlling the laser and transmits it to the host 31 through the laser output line, and the on and off and working state of the laser are controlled by the host 31.

[0087] Furthermore, a second connecting socket 222 is provided on the handheld laser transmitter head 22, the gas source box 4 also includes a solenoid valve, and the composite tube 41 also includes a second electric control line 412, one end of the second electric control line 412 is connected to the solenoid valve, and the other end is detachably connected to the second connecting socket 222; after the second electric control line 412 is connected to the second connecting socket 222, the handheld laser transmitter head 22 can control the solenoid valve through the second electric control line 412.

[0088] Preferably, the second electric control line connection end 4121 and the second connection seat 222 are magnetically connected to facilitate the connection and removal of the second electric control line 412 at any time, thereby avoiding damage to the second electric control line 412 caused by pulling during use.

[0089] Furthermore, the composite tube 41 is configured to wrap the air outlet pipe 411 and the second electric control line 412 with Velcro, so that the Velcro can be opened at any time to adjust the composite tube 41 .

[0090] Furthermore, the fixing seat 223 is detachably mounted on the handheld laser emitting head 22, the composite tube 41 is connected to the fixing seat 223, and the outlet pipe connection end 4111 and the second electric control line connection end 4121 are led out through the fixing seat 223. The fixing seat 223 is detachably mounted on the handheld laser emitting head 22, and the user can flexibly disassemble the fixing seat 223 and set the position of the fixing seat 223 as needed to meet different needs; since the second electric control line 412 is detachably connected to the second connection seat 222, the composite tube 41 is easily driven to detach from the second connection seat 222 when shaking, so the fixing seat 223 plays the role of fixing the composite tube 41, avoiding pulling the second electric control line 412, damaging the outlet pipe 411 and affecting the communication function of the second electric control line 412.

[0091] Furthermore, a quick connector 2231 is provided at the outlet pipe connection end 4111 where it leads out from the fixing seat 223. The quick connector 2231 is provided as a hard connector, which facilitates the disassembly and installation of the outlet pipe 411. At the same time, the quick connector 2231 protects the soft outlet pipe 411 from being squeezed, thereby preventing the outlet pipe 411 from being damaged and affecting gas transmission.

[0092] Furthermore, the gas source box 4 includes a gas storage device, and the gas outlet pipe connection end 4111 is connected to the end of the light emitting section 221 on the handheld laser transmitter 22 away from the light outlet 2215, so that the gas can be output from the light outlet 2215 through the light emitting section 221, and the protective gas is stored in the gas storage device. The gas improves the cutting speed and quality by measures such as assisting combustion, preventing oxidation and pollution, and cleaning the cutting seam, thereby ensuring that the handheld laser transmitter 22 can stably complete laser cutting and other tasks.

[0093] Alternatively, the gas storage device may be a gas cylinder or a gas pump.

[0094] Preferably, in order to reduce the volume, facilitate carrying and use for outdoor operations, the gas is stored in an air pump. When the air pump is installed in a gas source box, it has a smaller volume and a larger gas capacity, which reduces the burden on outdoor workers and facilitates operation.

[0095] See also Figure 5 and Figure 8 A high-pressure gas channel 2218 is opened in the handheld laser emitting head 22, and the gas outlet pipe connection end 4111 is connected to the entrance of the high-pressure gas channel 2218, so that the protective gas enters the high-pressure gas channel 2218. The gas passes through the emitting section 2216 together with the laser that has passed through the protective mirror assembly 2214 in the light emitting section 221 along the high-pressure gas channel 2218, and is emitted from the light outlet 2215. During the laser cutting process, the protective gas plays a role in assisting combustion, so that the laser output by the handheld laser emitting head 22 can better complete the cutting work.

[0096] Optionally, the gas can be controlled by a manual control valve or a solenoid valve connected to the gas storage device. Controlling the opening and closing of the gas by the manual control valve can improve the flexibility of the coordination between the gas storage device and the handheld laser transmitter head 22. The gas can be controlled by the manual control valve at any time during the operation, which is simple to operate and can improve safety and avoid safety accidents caused by improper operation or misoperation. Controlling the opening and closing of the gas by the solenoid valve can achieve precise adjustment and control of the gas flow, reduce operation delays, and improve the overall response speed of the system.

[0098] Furthermore, the handheld laser transmitting head 22 also includes a switch 224, which is electrically connected to the second connecting socket 222, and the first connecting socket 23 is electrically connected to the second connecting socket 222. The user controls the switch 224 to transmit an electrical signal to the second circuit board through the second electric control line 412. After the second circuit board receives the electrical signal, it converts the electrical signal into a signal for controlling the gas and a signal for controlling the laser, wherein the signal for controlling the gas is transmitted to the solenoid valve, and the gas storage device is controlled by the solenoid valve to control the on and off of the gas in the outlet pipe 411; the signal for controlling the laser is transmitted to the main unit 31 after passing through the second electric control line 412, the second connecting socket 222, the first connecting socket 23 and the first electric control line 321 in sequence to control the transmission of the laser, so that the various components in the laser generating device can work stably together.

[0099] Preferably, the switch 224 and the fixing seat 223 are detachably mounted on the handheld laser transmitting head 22 via a press buckle 2232. The press buckle 2232 allows the fixing seat 223 and the switch 224 to be more firmly mounted on the outer surface of the handheld laser transmitting head 22 to prevent slipping. The user can flexibly adjust the position of the switch 224 or remove the switch 224, so that the handheld laser transmitting head 22 can adapt to more complex and diverse usage environments.

[0100] Furthermore, a travel switch 225 connected in series with the switch 224 is provided on the handheld laser emitting head 22. The travel switch 225 is located on one side of the handheld laser emitting head 22 close to the laser output head 1. After the laser output head 1 is connected to the handheld laser emitting head 22, the protruding end of the stopper 121 is engaged with the travel switch 225. Only after the travel switch 225 is engaged, that is, when the laser output head 1 is stably connected, can the laser be output and the switch 224 work, so that the overall structure can operate stably. Through the second card slot 229 and the travel switch 225, two layers of protection are provided for the coordinated work of the handheld laser emitting head 22 and the laser output head 1, thereby improving the stability and safety of the coordinated work of the laser output head 1 and the handheld laser emitting head 22.

At this time, the signal for controlling the laser generated by the second circuit board commands the laser in the main unit 31. The signal for controlling the gas is transmitted to the solenoid valve and then transmitted to the gas storage device in the gas cylinder 4 through the output line 32 to realize the control of the gas in the gas outlet pipe 411.

[0102] As a feasible embodiment, the main unit 31 and the gas source box 4 are combined and arranged in the same box to reduce the burden of carrying for users.
