[0045] The embodiment of the present application provides a handheld laser, which is used to solve the technical problem that the handheld laser is inconvenient to use.

[0046] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the handheld laser includes a housing 1, a control unit 2, a first pump source 3 and a galvanometer assembly 4, and a handle 11 and a light outlet are formed on the housing 1. The control unit 2 is arranged in the housing 1, and the handle 11 and the control unit 2 are arranged in sequence along a first direction. The first pump source 3 is arranged in the housing 1, and the first pump source 3 is located below the handle 11. The first pump source 3 is used to emit a laser beam. The galvanometer assembly 4 is arranged in the housing 1, and the first pump source 3 and the galvanometer assembly 4 are arranged in sequence along a first direction, and the light outlet is located below the galvanometer assembly 4. Among them, the galvanometer assembly 4 and the first pump source 3 are both electrically connected to the control unit 2.

[0047] It can be understood that the up and down direction in this embodiment means that when a laser is used, the emission direction of the laser beam from the light outlet is the downward direction.

[0048] The galvanometer assembly 4 and the first pump source 3 are both electrically connected to the control unit 2 , so that the control unit 2 controls the first pump source 3 to emit a laser beam, and controls the galvanometer assembly 4 to adjust the emission direction of the laser beam from the light outlet.

[0049] The control unit 2 can control the first pump source 3 to emit a laser beam. Since the first pump source 3 and the galvanometer assembly 4 are arranged in sequence along the first direction, the galvanometer assembly 4 is located on the optical path of the laser beam emitted by the first pump source 3. Therefore, after the laser beam emitted by the first pump source 3 reaches the galvanometer assembly 4, the control unit 2 can control the galvanometer assembly 4 to adjust the emission direction of the laser beam from the light outlet, thereby scanning and marking the workpiece.

[0050] A focusing lens may be provided at the light outlet so as to focus the laser beam emitted from the light outlet through the focusing lens.

[0051] A handle 11 and a light outlet are formed on the shell 1 of the embodiment of the present application. The handle 11 can be convenient for users to hold, and the light outlet is used for emitting a laser beam. The galvanometer assembly 4 and the first pump source 3 are both electrically connected to the control unit 2 so that the laser beam can be controlled by the control unit 2 to mark the workpiece. Since the handle 11 and the control unit 2 as well as the first pump source 3 and the galvanometer assembly 4 are arranged in sequence along the first direction, the first pump source 3 is located below the handle 11, and the light outlet is located below the galvanometer assembly 4, the position distribution of the handle 11, the control unit 2, the first pump source 3 and the galvanometer assembly 4 is more reasonable, so as to make full use of the space in the shell 1, thereby facilitating the reduction of the volume of the shell 1. On the basis of minimizing the volume of the shell 1, the laser beam can be controlled for marking by the control unit 2, and the host computer is no longer required for control, thereby improving the convenience of user use.

[0052] In one embodiment, if Figure 2 As shown, the galvanometer assembly 4 includes a first drive unit 41 and a first galvanometer 42. The first drive unit 41 is disposed in the housing 1 and is electrically connected to the control unit 2. The first galvanometer 42 is disposed at the output end of the first drive unit 41. The first drive unit 41 is used to drive the first galvanometer 42 to rotate. The first pump source 3 and the first galvanometer 42 are sequentially disposed along the first direction.

[0053] The first pump source 3 and the first galvanometer 42 are sequentially arranged along the first direction, so that the laser beam emitted by the first pump source 3 can reach the first galvanometer 42, and the direction of the laser beam is changed by the first galvanometer 42, so as to mark the workpiece. The first driving unit 41 is electrically connected to the control unit 2, so that the first driving unit 41 is controlled by the control unit 2, and the rotation angle of the first galvanometer 42 is controlled by the first driving unit 41.

[0054] In one embodiment, if Figure 2As shown, the galvanometer assembly 4 also includes a second drive unit 43 and a second galvanometer 44. The second drive unit 43 is disposed in the housing 1, and the second drive unit 43 is electrically connected to the control unit 2. The second galvanometer 44 is disposed at the output end of the second drive unit 43, and the second drive unit 43 is used to drive the second galvanometer 44 to rotate. The rotation centerline of the second galvanometer 44 is parallel to the first direction, and the rotation centerline of the second galvanometer 44 is perpendicular to the rotation centerline of the first galvanometer 42. The light outlet is located below the second galvanometer 44.

[0055] The second driving unit 43 is electrically connected to the control unit 2 so that the second driving unit 43 can be controlled by the control unit 2, thereby controlling the rotation angle of the second galvanometer 44. The laser beam emitted by the first pump source 3 is reflected to the second galvanometer 44 by the first galvanometer 42, and then reflected to the light outlet by the second galvanometer 44, so that the laser beam is emitted from the light outlet to mark the workpiece. Through the reflection of the laser beam by the first galvanometer 42 and the second galvanometer 44, the laser beam can scan the workpiece to achieve marking of the workpiece.

[0056] The rotation center line of the second galvanometer 44 is parallel to the first direction, and the rotation center line of the second galvanometer 44 is perpendicular to the rotation center line of the first galvanometer 42, so that the laser beam emitted by the first pump source 3 is reflected to the light outlet through the first galvanometer 42 and the second galvanometer 44, so that the laser beam is emitted from the light outlet. The distance between the first galvanometer 42 and the second galvanometer 44 can be reduced, thereby reducing the volume of the housing 1.

[0057] In one embodiment, if Figure 1 and Figure 2 As shown, the control unit 2 includes a first control board 21 and a second control board 22, the first control board 21 is arranged in the housing 1, and the first pump source 3 is electrically connected to the first control board 21. The second control board 22 is arranged in the housing 1, and the galvanometer assembly 4 and the first control board 21 are both electrically connected to the second control board 22. The handle 11 and the first control board 21 and the second control board 22 are arranged in sequence along the first direction, and the second control board 22 is located below the first control board 21.

[0058] The first pump source 3 is electrically connected to the first control board 21, so as to control the first pump source 3 to emit a laser beam through the first control board 21. The galvanometer assembly 4 and the first control board 21 are both electrically connected to the second control board 22, so as to send instructions to the second control board 22 through the first control board 21, and then control the galvanometer assembly 4 through the second control board 22 to change the emission direction of the laser beam from the light outlet, so that the first control board 21 can coordinate the operation of the first pump source 3 and the galvanometer assembly 4.

[0059] The handle 11 and the first control panel 21 and the second control panel 22 are arranged in sequence along the first direction, and the second control panel 22 is located below the first control panel 21, so that the first control panel 21 and the second control panel 22 can make full use of the space in the shell 1 adjacent to the handle 11 along the first direction, thereby facilitating reducing the volume of the shell 1.

[0060] In one embodiment, if Figure 2 As shown, the control unit 2 also includes a third control board 23 , which is disposed in the housing 1 , and the first control board 21 and the galvanometer assembly 4 are both electrically connected to the third control board 23 ; the third control board 23 is located above the first control board 21 .

[0061] The first control board 21 can send instructions to the third control board 23, and then control the power-on voltage of the galvanometer assembly 4 through the third control board 23, so that the galvanometer assembly 4 can operate normally. Therefore, the first control board 21 can coordinate the operation of the first pump source 3 and the galvanometer assembly 4 through the second control board 22 and the third control board 23. The third control board 23 is located above the control board, so that the third control board 23 fully utilizes the space above the first control board 21, so that the volume of the housing 1 can be reduced.

[0062] In one embodiment, if Figure 2 As shown, the plane where the first control board 21 is located is perpendicular to the vertical plane, the plane where the second control board 22 is located is parallel to the vertical plane, and the plane where the third control board 23 is located is parallel to the plane where the first control board 21 is located. The plane where the first control board 21 is located and the plane where the second control board 22 is located are also parallel to the first direction.

[0063] Since the first pump source 3 and the galvanometer assembly 4 are arranged in sequence along the first direction, the plane where the second control board 22 is located is parallel to the vertical plane, and the galvanometer assembly 4 can be avoided, so that the galvanometer assembly 4 can be conveniently arranged in the housing 1. The plane where the first control board 21 is located is perpendicular to the vertical plane, which can reduce the vertical space occupied by the first control board 21 in the housing 1, thereby facilitating the reduction of the volume of the housing 1. Since the first control board 21 and the third control board 23 do not need to consider the installation interference problem with the galvanometer assembly 4, the plane where the third control board 23 is located is parallel to the plane where the first control board 21 is located, which can reduce the vertical space occupied by the first control board 21 and the third control board 23 in the housing 1.

[0064] In one embodiment, if Figure 1 and Figure 2As shown, the handheld laser further includes a second pump source 5, a first reflector 6 and a second reflector 7. The second pump source 5 is disposed in the housing 1, and the second pump source 5 is located between the first pump source 3 and the handle 11; the wavelength of the laser beam emitted by the second pump source 5 is smaller than the wavelength of the laser beam emitted by the first pump source 3, and the second pump source 5 is electrically connected to the control unit 2. The first reflector 6 is disposed between the first pump source 3 and the galvanometer assembly 4, and the laser beam emitted by the first pump source 3 can reach the galvanometer assembly 4 through the first reflector 6. The second reflector 7 is disposed between the second pump source 5 and the galvanometer assembly 4, and the second reflector 7 is located above the first reflector 6, and the second reflector 7 is used to reflect the laser beam emitted by the second pump source 5 toward the first reflector 6.

[0065] Since the wavelength of the laser beam emitted by the second pump source 5 is smaller than the wavelength of the laser beam emitted by the first pump source 3, the control unit 2 controls the first pump source 3 or the second pump source 5 to emit a laser beam of corresponding wavelength according to the material of the workpiece, thereby marking the workpiece.

[0066] After the laser beam emitted by the second pump source 5 reaches the second reflector 7, it can be reflected by the second reflector 7 toward the first reflector 6, and then reflected toward the galvanometer assembly 4 by the first reflector 6. The laser beam emitted by the first pump source 3 can directly pass through the first reflector 6 and directly reach the galvanometer assembly 4. The optical path of the laser beam emitted by the second pump source 5 after being reflected by the second reflector 7 and the first reflector 6 is the same as the optical path of the laser beam emitted by the first pump source 3 after passing through the first reflector 6, so that the laser beam can be reflected to the light outlet through the galvanometer assembly 4.

[0067] In one embodiment, if Figure 1 and Figure 2 As shown, the handheld laser also includes a focus barrel 8, which is detachably arranged on the housing 1, and the light outlet is connected to the focus barrel 8. When in use, the focus barrel 8 is installed on the housing 1 so that the focus position of the laser beam emitted from the light outlet is stabilized by the focus barrel 8. Avoid the distance emission change between the light outlet and the workpiece, which causes the focus of the laser beam to be unable to focus on the workpiece, affecting the marking of the workpiece. When marking is not required, the focus barrel 8 can be removed from the housing 1 to facilitate the storage or transportation of the housing 1 and the focus barrel 8. The focus barrel 8 can also prevent the laser from leaking out to prevent the laser beam from burning foreign objects.

[0068] It can be understood that when marking a workpiece, the fixed focus barrel 8 can be pressed against the workpiece to stabilize the distance between the light outlet and the workpiece, so as to focus the laser beam on the workpiece.

[0069] In one embodiment, if Figure 2As shown, the handheld laser also includes a detection sensor 9, which is arranged on the housing 1 and electrically connected to the control unit 2. The detection sensor 9 is used to detect whether there is a workpiece in the light emitting direction of the light emitting port. When the detection sensor 9 detects the workpiece, the control unit 2 controls the first pump source 3 to emit light normally to mark the workpiece. When the detection sensor 9 does not detect the workpiece, the control unit 2 controls the first pump source 3 to stop emitting light to avoid the risk of accidents caused by the laser beam irradiating the user.

[0070] In one embodiment, if Figure 1 and Figure 2 As shown, the handheld laser further includes a touch screen 10, which is disposed on the housing 1 and is electrically connected to the control unit 2. The control unit 2 can control the touch screen 10 to display data such as parameters of the laser beam. The user can also input instructions through the touch screen 10 so that the control unit 2 controls the first pump source 3 and the galvanometer assembly 4 to execute corresponding instructions.

[0071] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
