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.

[0024] Please refer to the attached document. Figures 1-5 This application provides a laser module clamping device 100, which is applied to a laser engraving machine and is used to quickly clamp the laser module 10.

[0025] Please refer to the attached document. Figures 1-5In this embodiment, the laser module clamping device 100 includes a laser module 10 and a clamping assembly 20. The laser module 10 includes a housing 11 and a laser head 12. The laser head 12 is mounted on the housing 11 and located inside the housing 11, with its output end exposed outside the housing 11. The laser head 12 is used for laser engraving of the workpiece. A guide rail 111 is provided on the rear side wall of the housing 11. The clamping assembly 20 is located on the rear side of the housing 11. The clamping assembly 20 includes a mounting base 21 and a clamping mechanism. The device includes a base 22 and an operating element 23; a mounting base 21 is a movable or fixed base for external installation; a clamping base 22 is movably connected to the mounting base 21 and moves relative to the mounting base 21; the operating element 23 swings relative to the mounting base 21 under manual operation and drives the clamping base 22 to move closer to the mounting base 21 to quickly clamp the guide rail 111, thereby realizing the quick clamping of the laser module 10 by the clamping base 22, avoiding the need to use tools for tightness adjustment, and improving the clamping convenience of the laser module clamping device 100.

[0026] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the laser module 10 includes a housing 11 and a laser head 12. The laser head 12 is installed in the housing 11 and is located inside the housing 11 so that the housing 11 can protect the laser head 12. The output end of the laser head 12 is exposed on the outside of the housing 11. The laser head 12 is used to laser engrave the workpiece to be engraved so as to achieve the engraving effect of the laser module 10. The rear side wall of the housing 11 is provided with a guide rail 111.

[0027] The clamping assembly 20 is located on the rear side of the housing 11. The clamping assembly 20 includes a mounting base 21, a clamping seat 22, and an operating member 23. The mounting base 21 is used to install on an external movable seat or fixed seat so that the clamping assembly 20 can be connected to the external movable seat or fixed seat through the mounting base 21. The clamping seat 22 is movably connected to the mounting base 21 and moves relative to the mounting base 21 so as to adjust the position of the clamping seat 22 relative to the mounting base 21. The operating member 23 swings relative to the mounting base 21 under human action and drives the clamping seat 22 to move closer to the mounting base 21 so as to quickly clamp the guide rail part 111, thereby realizing the quick clamping of the laser module 10 by the clamping seat 22, avoiding the need to use tools for tightness adjustment, and improving the clamping convenience of the laser module clamping device 100.

[0028] Please refer to the attached document. Figures 1-4In this embodiment, the mounting base 21 is connected to a guide shaft 211, through which a clamping seat 22 passes. The clamping seat 22 moves along the axis of the guide shaft 211. The operating member 23 is oscillatingly connected to the guide shaft 211 and is located outside the clamping seat 22 to facilitate adjustment of the position of the operating member 23 relative to the guide shaft 211. The operating member 23 is provided with a cam portion 231, which directly or indirectly contacts the outer wall of the clamping seat 22. The cam portion 231 drives the clamping seat 22 to move as the operating member 23 oscillates, causing the clamping seat 22 to clamp or release the guide rail portion 111. This allows the operating member 23 to abut against the clamping seat 22 and the guide rail portion 111 through the cam portion 231, thereby achieving rapid clamping of the laser module 10 by the clamping seat 22. This avoids the need for tools to adjust the tightness and improves the clamping convenience of the laser module clamping device 100.

[0029] Please refer to the attached document. Figures 1-5 In this embodiment, a first position 2311 and a second position 2312 are provided between the cam portion 231 and the outer wall of the clamping seat 22; this allows the operating member 23 to swing the cam portion 231 relative to the first position 2311 and the second position 2312 under manual operation. When the cam portion 231 is in the first position 2311, the end of the operating member 23 is close to the outer wall of the clamping seat 22, and the clamping seat 22 clamps the guide rail portion 111; thus, the clamping seat 22 clamps the laser module 10. When the cam portion 231 is in the second position 2312, the end of the operating member 23 is away from the outer wall of the clamping seat 22, and the clamping seat 22 releases the guide rail portion 111, thus, the clamping seat 22 releases the laser module 10. This avoids the need for tools to adjust the tightness and improves the clamping convenience of the laser module clamping device 100.

[0030] Please refer to the attached document. Figures 1-5 In this embodiment, the distance between the portion of the cam portion 231 relative to the first position 2311 and the swing axis of the cam portion 231 is A; the distance between the portion of the cam portion 231 relative to the second position 2312 and the swing axis of the cam portion 231 is B, where B is greater than A; the portion of the cam portion 231 relative to the first position 2311 and the portion of the cam portion 231 relative to the second position 2312 form a circular arc transition, which forms a gradual contour line, reduces contact stress concentration, reduces wear, and ensures that the torque of the cam portion 231 is smoothly transmitted when swinging, avoiding instantaneous overload caused by geometric abrupt changes.

[0031] Please refer to the attached document. Figures 1-4In this embodiment, the mounting base 21 is provided with a first through hole 21a, and the clamping base 22 is provided with a second through hole 22a, which connects to the first through hole 21a. The guide shaft 211 passes through the first through hole 21a and the second through hole 22a to allow the guide shaft 211 to pass through the mounting base 21 and the clamping base 22. One end of the guide shaft 211 is provided with a limiting part 2111, which contacts the mounting base 21 and is limited by the mounting base 21. The other end of the guide shaft 211 is hinged to the cam part 231 of the operating member 23, so that the cam part 231 and the limiting part 2111 of the operating member 23 respectively limit the two ends of the guide shaft 211, preventing the guide shaft 211 from disengaging from the mounting base 21 and the clamping base 22.

[0032] Please refer to the attached document. Figures 1-4 In this embodiment, a pad 24 is provided on the side of the clamping seat 22 facing the cam portion 231 of the operating member 23. The pad 24 is sleeved on the outer periphery of the guide shaft 211. The pad 24 is located between the cam portion 231 of the operating member 23 and the clamping seat 22, and continuously contacts the cam portion 231 of the operating member 23 and the clamping seat 22. The cam portion 231 of the operating member 23 contacts the pad 24 and applies force to the clamping seat 22 through the pad 24, so that the pad 24 can play a buffering role and ensure the contact effect of the cam portion 231 of the operating member 23 against the clamping seat 22.

[0033] Please refer to the attached document. Figures 1-4 In this embodiment, the mounting base 21 is provided with a first moving groove 21b; the clamping base 22 is movably connected to the first moving groove 21b and can move elastically relative to the mounting base 21; so that the clamping base 22 can move relative to the mounting base 21 through the space of the first moving groove 21b, thereby facilitating the clamping base 22 to move closer to or further away from the mounting base 21 during the movement, so as to clamp or release the guide rail 111 between the clamping base 22 and the mounting base 21.

[0034] The clamping seat 22 is provided with a clamping arm 221. As the clamping seat 22 approaches the mounting seat 21, the clamping arm 221 moves toward the guide rail portion 111 to contact the guide rail portion 111, so that the clamping arm 221 clamps the guide rail portion 111, so that the clamping seat 22 can clamp the guide rail portion 111 through the clamping arm 221.

[0035] Please refer to the attached document. Figures 1-4In this embodiment, an elastic element 25 is provided between the clamping seat 22 and the mounting seat 21. The two ends of the elastic element 25 contact the clamping seat 22 and the mounting seat 21 respectively, and apply an elastic force to the clamping seat 22 to maintain indirect or direct contact between them, facilitating elastic movement of the clamping seat 22 relative to the mounting seat 21 via the elastic element 25. Simultaneously, the elastic element 25 acts as a buffer, preventing excessive impact force during the clamping process when the clamping seat 22 moves relative to the mounting seat 21.

[0036] Please refer to the attached document. Figures 1-4 In this embodiment, the clamping seat 22 is provided with a second moving groove 22b. When the clamping seat 22 and the mounting seat 21 are in a loose state, there is a gap between the clamping seat 22 and the guide rail 111. The guide rail 111 is movably connected to the clamping seat 22 and moves along the second moving groove 22b to adjust the position of the laser module 10 relative to the clamping assembly 20. The second moving groove 22b is arranged in a vertical direction to facilitate the adjustment of the height position of the laser module 10 relative to the clamping assembly 20, thereby facilitating the laser module 10 to adapt to workpieces of different thicknesses.

[0037] In the second embodiment of the application, a laser engraving machine includes a laser module clamping device 100 and a laser engraving machine body. The laser engraving machine body supports the laser module clamping device 100 so that the laser module clamping device 100 is fixed to the laser engraving machine body.
