Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] Please refer to the attached document. Figures 1-5 This application provides a laser head assembly 100, which is applied to a laser engraving machine and is used for focusing at different heights.

[0043] Please refer to the attached document. Figures 1-5 In this embodiment, the laser head assembly 100 includes a housing 10, a heat sink 20, a laser engraving module 30, and a focusing component 40. The heat sink 20 is disposed inside the housing 10, and the heat sink 20 and the housing 10 form a receiving groove 20a. The laser engraving module 30 is mounted on the heat sink 20 and exchanges heat with the heat sink 20. The laser engraving module 30 is used for laser engraving of the workpiece to be engraved. The focusing component 40 is retractably connected to the housing 10 and can retract or extend relative to the receiving groove 20a. This allows for adjustment of the position of the focusing component 40 relative to the housing 10, enabling multiple position adjustments of the focusing component 40 to achieve focusing at different heights. This avoids the limitation of the focusing component 40 not being able to be adjusted in multiple positions relative to the housing 10, thus improving the versatility of the laser head assembly 100. The focusing element 40 is locked to the housing 10 to maintain the position of the focusing element 40 relative to the housing 10, ensuring the positional accuracy of the focusing element 40 relative to the housing 10, improving the focusing accuracy of the focusing element 40, and avoiding free adjustment of the focusing element 40 relative to the housing 10.

[0044] Please refer to the attached document. Figures 1-3 In this embodiment, the outer shell 10 serves as a support component of the laser head assembly 100, and the outer shell 10 is used to support the heat sink 20, the laser engraving module 30, and the focusing component 40.

[0045] Please refer to the attached document. Figures 1-2 In this embodiment of the application, the heat sink 20 is disposed inside the outer shell 10 and connected to the lower end of the outer shell 10 so as to fix the heat sink 20 to the outer shell 10. The heat sink 20 and the outer shell 10 form a receiving groove 20a.

[0046] Please refer to the attached document. Figures 1-3 In this embodiment, the laser engraving module 30 is installed on the heat sink 20 and exchanges heat with the heat sink 20; so that the heat generated by the laser engraving module 30 during operation can be conducted to the heat sink 20 to achieve the heat dissipation effect of the laser engraving module 30, reduce the temperature of the laser engraving module 30, and avoid the laser engraving module 30 from being too hot. The laser engraving module 30 is used to laser engrave the workpiece to be engraved, so that the laser engraving module 30 can laser engrave the workpiece to be engraved, so that the workpiece to be engraved can be adjusted from a semi-finished product state to a finished product state.

[0047] Please refer to the attached document. Figures 1-4 In this embodiment, the focusing element 40 is retractably connected to the housing 10 and can retract or extend relative to the receiving groove 20a to adjust the position of the focusing element 40 relative to the housing 10. This allows for multiple position adjustments of the focusing element 40 to achieve focusing at different heights, avoiding the limitation of the focusing element 40 being unable to be adjusted in multiple positions relative to the housing 10, and improving the versatility of the laser head assembly 100. The focusing element 40 is locked to the housing 10 to maintain its position relative to the housing 10, ensuring the positional accuracy of the focusing element 40 relative to the housing 10, improving the focusing accuracy of the focusing element 40, and avoiding free adjustment of the focusing element 40 relative to the housing 10. Optionally, the bottom of the focusing element 40 can be a flat end, a beveled end, or a sharp end.

[0048] Please refer to the attached document. Figures 1-3 The heat sink 20 is provided with a receiving groove 20a, which extends along the length of the heat sink 20. The focusing component 40 passes through the receiving groove 20a so that the focusing component 40 can make full use of the space of the receiving groove 20a. The focusing component 40 is guided to the heat sink 20 so that the focusing component 40 can extend and retract under the guidance of the heat sink 20, which improves the smoothness of the extension and retraction of the focusing component 40 and avoids the focusing component 40 from shifting its position during the extension and retraction process.

[0049] Please refer to the attached document. Figures 1-3 The inner wall of the receiving groove 20a is a guide sidewall, so that the focusing component 40 can extend and retract along the inner wall of the receiving groove 20a; the two side walls of the focusing component 40 can contact the guide sidewall, so that the two side walls of the focusing component 40 are restricted by the guide sidewall, and the focusing component 40 is guided by the guide sidewall, so that the focusing component 40 can extend and retract under the guidance of the guide sidewall, thereby improving the smoothness of the extension and retraction of the focusing component 40 and preventing the focusing component 40 from deviating from the guide sidewall during the extension and retraction process.

[0050] Please refer to the attached document. Figures 1-3The outer casing 10 is provided with a through hole 10a, which connects to the receiving groove 20a. The laser head assembly 100 also includes an operating member 50, which passes through the through hole 10a so that the operating member 50 can extend into the receiving groove 20a through the hole 10a. The operating member 50 is connected to the focusing member 40 so that the operating member 50 can be fixed to the focusing member 40. The operating member 50 is used for user operation or movement so that the user can operate or move the operating member 50 to drive the focusing member 40 to extend or retract, thereby facilitating the extension and retraction of the focusing member 40 relative to the receiving groove 20a under the action of external force, and improving the extension and retraction convenience of the focusing member 40.

[0051] Please refer to the attached document. Figures 1-3 The outer casing 10 is arranged vertically, and the through hole 10a extends along the length of the outer casing 10, connecting to the receiving groove 20a at different positions. This allows the operating member 50 to move along the length of the outer casing 10, facilitating the extension and retraction of the focusing member 40 along the length of the outer casing 10. This, in turn, allows for adjustment of the height of the focusing member 40, enabling focusing at different heights. Optionally, the through hole 10a is an elongated hole, allowing the height of the focusing member 40 to be adjusted by positioning the operating member 50 at different heights within the elongated hole.

[0052] Please refer to the attached document. Figures 1-5 The operating component 50 is provided with an operating part 51 and a connecting part 52. The connecting part 52 is connected to the operating part 51 so that the connecting part 52 can be fixed to the operating part 51. The operating part 51 is exposed on the outside of the housing 10 and is used for operation or movement by the user, so that the user can operate or move the operating part 51 in the external environment, thereby facilitating the user to operate or move the operating component 50 through the operating part 51. The connecting part 52 moves with the operation part 51. The connecting part 52 is provided with a through hole 10a so that the connecting part 52 extends into the receiving groove 20a through the hole 10a. The connecting part 52 is connected to the focusing component 40 so that the operating part 51 can be connected to the focusing component 40 through the connecting part 52, thereby facilitating the extension and retraction of the focusing component 40 as the operating part 51 moves.

[0053] Please refer to the attached document. Figures 1-5 The operating part 51 rotates under the user's operation; the connecting part 52 is screwed to the focusing part 40 so that the connecting part 52 can be connected to the focusing part 40 by screwing. As the connecting part 52 rotates, the focusing part 40 gradually moves closer to the inner wall of the outer shell 10 so that the inner wall of the outer shell 10 and the thread of the connecting part 52 limit the position of the focusing part 40, so that the focusing part 40 is locked to the outer shell 10, ensuring the positional accuracy of the focusing part 40 relative to the outer shell 10, improving the focusing accuracy of the focusing part 40, and avoiding the free adjustment of the focusing part 40 relative to the outer shell 10.

[0054] Please refer to the attached document. Figures 1-3The laser engraving module 30 includes a laser element 31 and a laser head 32. The laser element 31 is disposed inside the heat sink 20 and connected to the heat sink 20. The laser head 32 is connected to the laser element 31 and exposed on the outside of the heat sink 20. The laser output by the laser element 31 is transmitted to the external environment through the laser head 32 and performs laser engraving on the workpiece to be engraved in the external environment.
