[0067] The laser assembly 300 is used to output laser to realize laser engraving, laser cutting, laser welding, laser marking and other laser machining operations. The laser host 301 of the laser assembly 300 is used to generate laser, and the laser generated by the laser host 301 is conducted to the laser output head 302 through the optical fiber 303, and the laser is emitted outward from the laser output head 302 for laser machining.

[0070] In an embodiment, the laser assembly 300 and the shell 100 are arranged in a detachable manner. In this arrangement, the laser assembly 300 can be separated from the shell 100 as a whole to be used independently of the shell 100, so as to improve the use convenience. The optical fiber 303 can be detachably connected with the laser output head 302, so that when the laser assembly 300 and the shell 100 need to be disassembled, the optical fiber 303 is limited to be separated from the laser output head 302, so that the optical fiber 300 can be inserted into or pulled out of the shell 100. Optionally, a threading groove 13 can be arranged as in the following embodiment, and the optical fiber 303 can be disassembled from the slot of the threading groove 13, so that the laser assembly can be disassembled as a whole without disassembling the optical fiber 303 and the laser output head 302.

[0071] For reference Figure 1 and Figure 2 In an embodiment, the shell 10 is provided with a threading groove 13 located at the opening edge of the processing space 11, and the optical fiber 303 is arranged in the threading groove 13.

[0072] In the embodiment, the shell 10 is further provided with a threading groove 13. The threading groove 13 is located at the edge of the opening of the shell 10. The threading groove 13 has a groove opening and threading openings at both ends of the threading groove 13. The threading groove 13 is used for threading the optical fiber 303 of the laser assembly 300. The optical fiber 303 can enter and exit the threading groove 13 from the groove opening of the threading groove 13, which facilitates the disassembly and assembly of the laser assembly 300 to switch the use state of the laser assembly 300. Optionally, when the shell 100 is in the closed state, the cover body 20 can cover the opening of the processing space 11 and the groove opening of the threading groove 13, or can only cover the opening of the processing space 11. In the closed state, the cover body 20 limits the optical fiber 303, which can prevent the optical fiber 303 from being pulled out of the groove opening of the threading groove 13. In addition, the threading groove 13 is arranged on the shell 10, which can limit the optical fiber 303 when the cover body 20 is opened, thereby preventing the optical fiber 303 from moving with the opening and closing of the cover body 20, and preventing the optical fiber 303 from moving randomly in the open state.

[0073] For reference Figure 1 and Figure 2 In an embodiment, the shell 10 is provided with a front opening and a top opening which are connected, and the threading groove 13 is located at the edge of the top opening.

[0074] In the embodiment, the laser processing device 1000 is defined to have a front-rear direction. The opening of the processing space 11 arranged on the shell 10 includes a front opening and a top opening which are connected to each other. Correspondingly, the cover body 20 includes a front cover 21 and a top cover 22 which are connected and arranged at an angle. The side of the top cover 22 away from the front cover 21 is rotationally connected to the shell 10. The rotation shaft 6026 can be used for rotationally connecting, or a hinge can be used for rotationally connecting, so that the cover body 20 can be flipped up and down relative to the shell 10. In the closed state, the top cover 22 covers the top opening of the shell 10, and the front cover 21 covers the front opening of the shell 10. The front opening and the top opening are arranged to make the opening of the processing space 11 relatively large, so as to have a large operation space, facilitate the disassembly and assembly of the components in the processing space 11, and avoid the components and the processing workpiece from colliding with the shell 10 when entering and exiting the processing space 11.

[0075] The threading groove 13 for threading the optical fiber is arranged at the edge of the top opening, which can make the threading groove 13 arranged at a position relatively far away from the front opening, so that the optical fiber 303 threaded into the processing space 11 is located at the rear side of the laser output head 302, thereby reducing the interference of the optical fiber 303 with the laser output head 302 and the moving assembly 200, and reducing the influence of the optical fiber 303 on the laser processing.

[0076] For reference Figure 1In an embodiment, the shell 100 further comprises a wire pressing part 14, which is arranged in the slot opening of the wire slot 13 in a foldable manner. In this way, when the optical fiber 303 is arranged in the wire slot 13, the wire pressing part 14 is folded in the slot opening of the wire slot 13 to prevent the optical fiber 303 from being pulled out of the wire slot 13, so as to better limit the optical fiber 303.

[0077] Please refer to Figures 3 to 6 In an embodiment, the laser processing device 1000 further comprises at least one wire clamping seat 30 arranged on the shell 10 and / or the moving assembly 200, and the wire clamping seat 30 is provided with a wire clamping groove penetrating through two ends; the laser assembly 300 further comprises at least one wire clamp 304 connected with the optical fiber 303, and the wire clamp 304 is arranged in the wire clamping groove of any wire clamping seat 30 in a detachable manner.

The number of the wire clamp 304 on the optical fiber 303 can be the same as or different from the number of the wire clamping seat 30 arranged in the laser processing device 1000. In addition, the wire clamp 304 can be clamped in the wire clamping groove as a whole, or part of the wire clamp 304 can be clamped in the wire clamping groove, which is not limited herein.

[0079] When the optical fiber 303 needs to be removed, the wire clamp 304 only needs to be separated from the clamping groove 34, and the optical fiber 303 is convenient to disassemble. Since the wire clamping seat 30 is fixed at a fixed position, the wire clamp 304 is limited by the limiting structure 314 when located in the clamping groove 34, so that the wire clamp 304 cannot move in the penetrating direction of the wire clamping groove, which can avoid the optical fiber 303 from slipping in the length direction, improve the stability of the fixed optical fiber 303, and also make the optical fiber 303 installed at the same position after being removed and reinstalled, thereby ensuring the consistency of the installation position of the optical fiber 303.

[0080] Optionally, the wire clamp 304 can be sleeved on the optical fiber 303, or can be connected to part of the outer wall of the optical fiber 303; the wire clamp 304 can be provided with a wire fixing structure for connecting the optical fiber 303, the wire fixing structure can be a binding part or can be a fastening hole 3044a for sleeving the binding part, the optical fiber 303 is connected with the wire clamp 304 by binding; or the wire fixing structure can be a top holding structure 3043 as in the following embodiment.

[0081] Referring to Figure 3 In an embodiment, the threading groove 13 is provided with a wire clamping seat 30.

The mounting bracket 203 is arranged on the second sliding rail 202 and can slide along the second sliding rail 202 and slide along the first sliding rail 201 with the second sliding rail 202. The clamping mechanism 205 for clamping the laser output head 302 is arranged on the mounting bracket 203, so that the laser output head 302 can be moved to different areas for laser processing. In some embodiments, the clamping mechanism 205 is arranged on the mounting bracket 203 in a lifting manner and can be driven by the lifting mechanism 204 to lift relative to the mounting bracket 203, so as to adjust the height of the laser output head 302.

At least one wire clamping seat 30 is arranged on the rear surface of the second sliding rail 202. When the laser output head 302 is clamped on the clamping mechanism 205, at least one wire clamp 304 connected to the optical fiber 303 can be clamped and matched with the wire clamping seat 30 on the second sliding rail 202, so as to fix the wiring path of the optical fiber 303 and limit the optical fiber 303, avoiding the optical fiber 303 from moving randomly and interfering with the moving assembly 200. Among them, the part of the optical fiber 303 close to the laser output head 302 is used as a movable section. This part of the optical fiber 303 can be bent or stretched when the laser output head 302 slides along the second sliding rail 202, so as to ensure that the laser output head 302 can slide on the second sliding rail 202.

The connecting strength is high, and the wire clamping seat 30 can be detachably arranged, so that the position of the wire clamping seat 30 can be replaced and the wire clamping seat 30 can be reused.

[0109] Referring to Figures 11 to 14In an embodiment, the clamping mechanism 205 comprises a support 2051 having a first end 2051a and a second end 2051b arranged at intervals, and a pressing structure, one end of which is hinged to the second end 2051b and the other end is clamped to the first end 2051a, the pressing structure and the support 2051 form a mounting space 2055, and the laser output head 302 is detachably clamped in the mounting space 2055.

[0110] In the embodiment, the support 2051 is used to connect with the device body, and can adopt at least one connection mode such as bolt connection, clamping, insertion, bonding, magnetic attraction connection and binding fixation, but is not limited thereto. The support 2051 has a first end 2051a and a second end 2051b arranged at intervals, and one end of the pressing structure is hinged to the second end 2051b, so that the pressing structure can be arranged to be opened and closed relative to the support 2051, and the laser output head 302 is detachably clamped in the mounting space 2055 formed by the pressing structure and the support 2051; the other end of the pressing structure is clamped to the first end 2051a, without the need to use bolts or other locking accessories for locking, and the disassembly and assembly are convenient.

[0112] In the embodiment, the clamping mechanism 205 comprises a support 2051, a pressing block 2052 and a buckling member 2053. The first end 2051a of the support 2051 is provided with a hook 2051c. The first connecting end 2052c of the pressing block 2052 is hingedly connected to the second end 2051b of the support 2051, so that the pressing block 2052 can rotate relative to the support 2051, so that the second connecting end 2052d of the pressing block 2052 can be close to or away from the hook 2051c. The rotation of the pressing block 2052 relative to the support 2051 defines a pressing position and an open position. When the pressing block 2052 is in the pressing position, the distance between the second connecting end 2052d and the hook 2051c is less than that when the pressing block 2052 is in the open position. When the pressing block 2052 is in the pressing position, the pressing block 2052 and the support 2051 enclose a mounting space 2055 for clamping the laser output head 302. When the pressing block 2052 is in the open position, the mounting space 2055 is open, and the laser output head 302 can freely enter and exit the mounting space 2055.

When the pressing block 2052 is in the pressing position, the buckling member 2053 can be buckled with the hook 2051c, so as to lock the pressing block 2052 and the support 2051 relative to each other, to avoid the opening of the mounting space 2055, so as to stably clamp the laser output head 302.

[0113] Please refer to Figure 13 and Figure 14 In an embodiment, the buckling member 2053 can rotate relative to the pressing block 2052.

[0114] In the embodiment, the buckling member 2053 can be directly rotatably connected with the second connecting end 2052d of the pressing block 2052, or can be rotatably connected with the handle 2054 as in the following embodiment. By rotatably arranging the buckling member 2053 relative to the pressing block 2052, the buckling member 2053 can be buckled or separated from the hook 2051c by only rotating the buckling member 2053, without rotating the pressing block 2052 at the same time, so that the buckling member 2053 is more flexible, and the buckling member 2053 can be buckled or separated from the hook 2051c without being excessively interfered by the pressing block 2052. In addition, when installing the laser output head 302, the buckling member 2053 can be first rotated to a suitable position, and then the pressing block 2052 is pressed against the laser output head 302, and then the buckling member 2053 is buckled with the hook 2051c.

[0115] Please refer to Figure 15 In an embodiment, the clamping mechanism 205 further comprises a handle 2054, one end of the handle 2054 is hingedly connected with the second connecting end 2052d, and the hinged position is a first hinged position 2054a. The buckling member 2053 is hingedly connected with the handle 2054, and the hinged position is a second hinged position 2054b. The first hinged position 2054a and the second hinged position 2054b are eccentrically arranged. When the pressing block 2052 is in the pressing position, the handle 2054 has a locked state and an unlocked state relative to the pressing block 2052. When the handle 2054 is in the locked state, the buckling member 2053 is buckled with the hook 2051c. When the handle 2054 is in the unlocked state, the buckling member 2053 is separated from the hook 2051c.

Wherein, when the handle 2054 is rotated to the locked state, the clamping piece 2053 can be clamped and locked with the hook 2051c when the pressing block 2052 is in the pressing position; when the handle 2054 is rotated to the unlocked state, the clamping piece 2053 is separated from the hook 2051c. This arrangement does not need to directly operate the clamping piece 2053, and the operation arm is lengthened by the handle 2054, which facilitates the clamping piece 2053 to be clamped with or separated from the hook 2051c, and improves the operation convenience.

[0117] Optionally, in the embodiment, when the clamping piece 2053 is clamped with the hook 2051c, the clamping end 2053a, the first hinged position 2054a and the second hinged position 2054b of the clamping piece 2053 can be located on the same line, and the first hinged position 2054a is located between the clamping end 2053a and the second hinged position 2054b. Alternatively, the clamping end 2053a, the first hinged position 2054a and the second hinged position 2054b of the clamping piece 2053 can not be located on the same line, for example, in the following embodiment, when the clamping piece 2053 is clamped with the hook 2051c, the first connecting line 2054d between the clamping end 2053a and the first hinged position 2054a and the second connecting line 2054e between the clamping end 2053a and the second hinged position 2054b are not collinear, so as to improve the clamping strength of the clamping piece 2053 and the hook 2051c, and improve the pressure of the pressing block 2052 to the laser output head 302.

[0118] Please refer to Figure 15 In an embodiment, when the clamping piece 2053 is clamped with the hook 2051c and the handle 2054 is in the locked state, the connecting line between the clamping end 2053a and the first hinged position 2054a of the clamping piece 2053 is the first connecting line 2054d, the connecting line between the clamping end 2053a and the second hinged position 2054b is the second connecting line 2054e, and the second connecting line 2054e is located on the side of the first connecting line 2054d towards the mounting space 2055.

[0119] In the embodiment, the handle 2054, the clamping piece 2053 and the pressing block 2052 form a lever and eccentric wheel structure; specifically, when the handle 2054 is in the unlocking state, the handle 2054 is in the relaxed state, and at this time, the clamping piece 2053 is separated from the hook 2051c; when the handle 2054 is rotated from the unlocking state to the locking state, the clamping end 2053a of the clamping piece 2053 gradually approaches the hook 2051c, and the clamping end 2053a is first overlapped with the hook 2051c, at this time, the handle 2054 has not reached the locking position, and the handle 2054 is continuously rotated, at this time, the second hinge position 2054b and the clamping piece 2053 are rotated to the side close to the mounting space 2055 with the rotation center of the handle 2054, i.e., the first hinge position 2054a as the lever fulcrum, so as to make the clamping piece 2053 tightly clamp the hook 2051c, so that the second line 2054e between the clamping end 2053a of the clamping piece 2053 and the second hinge position 2054b is located on the side of the first line 2054d between the clamping end 2053a and the first hinge position 2054a, which is toward the mounting space 2055, at this time, the direction of the reaction force of the locking piece on the handle 2054 is not in the same direction as the tangent direction of the rotation center of the handle 2054, a self-locking structure is formed between the handle 2054, the clamping piece 2053, the hook 2051c and the pressing block 2052, so that the handle 2054 is in the clamped locking state, thereby ensuring that the clamping piece and the hook 2051c are stably clamped and will not be loosened, and the laser head clamping mechanism 205 can stably clamp the laser head.

[0120] Among them, the manual force arm L for driving the handle 2054 to lock is between the operating end of the handle 2054 and the second hinge position 2054b, and the force arm L for locking the clamping piece 2053 and the hook 2051c is between the first hinge position 2054a and the second hinge position 2054b, by lengthening the length of the handle 2054, the force arm L of the handle 2054 is greater than the self-locking force arm L, so that the pressure required for manual operation is much smaller than the clamping force, and a smaller operating force can be used to lock the laser head clamping mechanism 205 to reliably clamp the laser head, improving the operation convenience.

[0121] It should be noted that in the embodiment, the first line 2054d and the second line 2054e are not physical structures, and the included angle a of the first line 2054d and the second line 2054e can be 1°, 5°, 10°, 15°, 30° or any value greater than 0, which is not limited here.

[0122] Please refer to Figure 15In an embodiment, the surface of the handle 2054 facing the pressing block 2052 is provided with an abutting portion 2054c, which abuts against the pressing block 2052 when the handle 2054 is in the locked state.

[0123] In this way, the handle 2054 and the pressing block 2052 also have interaction force in the pressing direction, at this time, the component force of the force acting on the handle 2054 by the locking member is opposite to the direction of the force acting on the handle 2054 by the pressing block 2052, which is beneficial to lock the handle 2054; and the pressure of the handle 2054 on the pressing block 2052 is also beneficial to clamp the laser output head 302 by the pressing block 2052, so that the clamping mechanism 205 can maintain a relatively stable clamping state, and the laser output head 302 can be reliably clamped.

In addition, the positioning column 2051e and the positioning hole 3021c can provide a supporting force for the laser output head 302 in the height direction and limit the laser output head 302 in the height direction, so as to avoid the sliding of the laser output head 302 in the mounting space 2055 and improve the connection strength and relative position stability of the laser output head 302 and the clamping mechanism 205.

The optical axis segment 4032f of the screw rod 4032d is arranged in the through hole 4011b of the base 401, and is sleeved with the sealing member 406. The sealing member 406 is arranged to seal the gap between the optical axis segment 4032f and the hole wall of the through hole 4011b, so as to prevent the dust or the debris in the machining process from adhering to the threaded segment 4032e or the orthogonal gear pair 4032a through the through hole 4011b, and thus avoid the dust and other impurities from affecting the transmission effect and stability of the transmission structure 4032. The sealing member 406 can be a V-shaped sealing ring, a Y-shaped sealing ring, a YX-shaped sealing ring or other sealing structures.

[0168] Please refer to Figure 24 and Figure 25 In an embodiment, the fixing seat 404 further comprises a second mounting structure 4042 arranged at an angle with the first mounting structure 4041, the second mounting structure 4042 is connected with the base 401 and is provided with a second mounting hole 4042a coaxial with the through hole 4011b; the driven driving member 4032c comprises a second rotating shaft 6026 and a second engaging part connected with each other, the second engaging part is engaged with the first engaging part, and the second rotating shaft 6026 is rotatably arranged in the second mounting hole 4042a.

[0170] Please refer to Figure 23 In an embodiment, the material clamping assembly 400 further comprises a second bearing 4037 arranged in the second mounting hole 4042a and sleeved with the second rotating shaft 6026.

[0171] In this way, the second rotating shaft 6026 can avoid directly contacting the hole wall of the second mounting hole 4042a, thereby avoiding mutual friction between the second rotating shaft 6026 and the hole wall of the second mounting hole 4042a when the driven driving member 4032c rotates. When the driven driving member 4032c rotates, the inner ring and the outer ring of the second bearing 4037 relatively rotate, so that the rotation process of the driven driving member 4032c is more stable. Optionally, two second bearings 4037 can be sleeved on the second rotating shaft 6026, so as to reduce friction and limit the driven driving member 4032c in the axial direction. The two second bearings 4037 can be arranged as two angular contact bearings, or one of the second bearings 4037 can be arranged as a thrust ball bearing, and the other bearing can be arranged as a deep groove ball bearing.

[0172] Optionally, a limiting step 6023g facing away from the second meshing part can be arranged on the side wall of the second rotating shaft 6026, so that the inner ring of the second bearing 4037 abuts against the limiting step 6023g to limit the second bearing 4037. In addition, a stop step or other stop structure can be arranged on the hole wall of the second mounting hole 4042a, and the stop structure abuts against the outer ring of the second bearing 4037, so as to avoid the second bearing 4037 and the driven driving member 4032c moving in the axial direction in the second mounting hole 4042a, thereby improving the stability of the overall structure. When two second bearings 4037 are arranged, the outer rings of the two second bearings 4037 can abut against two sides arranged in opposite directions of the stop step.

[0173] Please refer to Figure 23 and Figure 25 In an embodiment, the transmission structure 4032 further comprises a stop piece 407 sleeved on the second rotating shaft 6026 and abutting against one side of the inner ring of the second bearing 4037 away from the second meshing part. In this way, the second bearing 4037 can be limited, so as to avoid the second bearing 4037 moving in the axial direction of the second rotating shaft 6026, thereby ensuring the stability of the relative position of the second bearing 4037 and the second rotating shaft 6026 in the axial direction. The connection mode of the stop piece 407 and the second rotating shaft 6026 can adopt interference fit, threaded connection or use a jackscrew to fix.
