[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0029] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this application includes any and all combinations of one or more of the relevant listed items.

[0030] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0031] This application provides a laser engraving machine, such as Figures 1 to 3 As shown, in one embodiment, the laser engraving machine 100 includes a frame 10 , a locking member 20 and a host 30 .

[0032] The frame 10 can serve as a supporting structure of the entire laser engraving machine 100 and provide a stable installation base for other components. The frame 10 is connected to a mounting plate 11 , which is used to support and install the host 30 .

[0033] Part of the host 30 is supported on the top surface of the mounting plate 11 . The host 30 should include necessary or unnecessary structures such as a laser emitter.

[0034] The mounting plate 11, locking member 20, and fixing base 31 form the mounting structure of the main unit 30, enabling quick connection and locking between the main unit 30 and the mounting plate 11. The locking member 20 is vertically movably connected to the mounting plate 11 and has a first and second state, capable of rotating relative to the mounting plate 11 to switch between the two states. The fixing base 31 is connected to the main unit 30 and has a vertically extending sliding channel 311 extending therethrough. The fixing base 31 also has a retaining slot 312 on its side facing away from the mounting plate 11.

[0035] A latch 21 is provided at the top of the locking member 20. When the locking member 20 is in the first position, the latch 21 is located within the sliding channel 311. Because the sliding channel 311 is continuous, the locking member 20 and the latch 21 can move vertically within the sliding channel 311. The operator can move the host 30 to disengage the latch 21 and the mounting plate 11, thereby meeting the requirements for handheld use of the host 30. After the host 30 is placed on the mounting plate 11 in a preset position, the locking member 20 can be rotated to the second position, and the latch 21 is moved into the slot 312, thereby locking the host 30 with the mounting plate 11 and securing it to the frame 10 for use. The combination of the locking member 20 and the slot 312 ensures the stability of the host 30 during operation and reduces the risk of displacement due to vibration or external forces.

[0036] In this embodiment, the main unit 30 and the mounting plate 11 are locked by the cooperation of the locking member 20 and the fixing seat 31, and the main unit 30 can be quickly installed and disassembled by a simple rotation operation, which facilitates the use or maintenance of the laser engraving machine 100 in different working scenarios and improves work efficiency.

[0037] In one embodiment, the frame 10 includes a base 12 and columns 13. The base 12 is formed with a support surface for supporting consumables, such as the material to be engraved. The columns 13 are connected to the base 12 and are equipped with a lifting drive. The movable end of the lifting drive is connected to the mounting plate 11 to drive the mounting plate 11 downward toward or upward away from the base 12, adjusting the distance between the laser emitter and the consumable. This allows the laser engraver 100 to accommodate consumables of varying thicknesses and engraving depths, enhancing its versatility and processing flexibility.

[0038] The base 12 is provided with a detachable engraving plate and a consumables positioning device. The engraving plate and the base 12 are detachably connected by means of threads, magnets, etc. The consumables positioning device is used to determine the placement of the consumables, thereby improving the consistency of the engraving position during mass production. The specific structure of the engraving plate and consumables is not described in detail in this application.

[0039] The supporting surface can be a flat, smooth plane to maintain a close fit with the consumables. It can also be formed with a lattice-shaped projection or a tooth-like structure arranged in a specific direction, thereby reducing the contact area with the consumables and facilitating laser cutting. When the supporting surface is formed with a lattice-shaped projection, the protrusion height should be consistent, that is, the highest point of the projection should be on the same cross-section. When the supporting surface is formed with a tooth-like structure arranged in a specific direction, the tooth tips of the tooth structure should be arranged in the same plane.

[0040] The lifting drive member can use a lifting structure commonly used in this field, such as a motor-driven screw lifting mechanism, a pneumatic or hydraulic lifting mechanism, an electric push rod lifting mechanism or a linear motor lifting mechanism, and this application does not limit this.

[0041] A mounting cavity can be provided within the column 13, where the lifting drive is housed, providing protection for the lifting mechanism. A port is defined in the sidewall of the column 13, connecting to the mounting cavity. The mounting plate 11 connects to the movable end of the lifting drive through the port. It is important to note that the port extends vertically for a certain distance to prevent interference with the sidewall of the column 13 during its upward and downward movement, ensuring smooth lifting.

[0042] The mounting plate 11 is L-shaped, that is, the mounting plate 11 includes a first plate body and a second plate body connected at a right angle. The first plate body is connected to the movable end of the lifting drive member, and the second plate body is used to install the locking member 20.

[0043] Please refer to Figure 4 and Figure 5 The mounting plate 11 has a mounting channel 111, and a limiting plate 112 is provided on the inner wall of the mounting channel 111 to separate the mounting channel 111 into a first channel 1111 and a second channel 1112. A third channel 1121 is opened on the limiting plate 112, and the third channel 1121 connects the first channel 1111 and the second channel 1112; the mounting channel 111 is formed on the second plate body, and the mounting channel 111 includes a first channel 1111, a third channel 1121 and a second channel 1112 connected in sequence from bottom to top, wherein the aperture of the third channel 1121 is smaller than the aperture of the first channel 1111 and the second channel 1112, and the physical structure between the inner wall of the third channel 1121 and the inner wall of the first channel 1111 / second channel 1112 is defined as the limiting plate 112.

[0044] Please refer to Figure 6The locking member 20 includes an elastic member 25 and a screwing end 22, a rotating shaft 23 and a stop plate 24 connected in sequence along the vertical direction. The rotating shaft 23 connects the various components of the locking member 20 to form a whole, keeping relative rotation and movement impossible.

[0045] The rotating shaft 23 passes through the third channel 1121, with its ends connected to the screwing head 22 and the latch 21, respectively. Specifically, the lower portion of the rotating shaft 23 is located in the first channel 1111, and the upper portion of the rotating shaft 23 is located in the second channel 1112. The screwing head 22 is connected to the end of the rotating shaft 23 near the first channel 1111, and the latch 21 is connected to the end of the rotating shaft 23 near the second channel 1112 and is arranged perpendicular to the rotating shaft 23. The operator can rotate the screwing head 22, thereby driving the entire locking member 20 to rotate. The stop plate 24 is connected to the outer wall of the rotating shaft 23 and is located in the second channel 1112. The stop plate 24 can cooperate with the limit plate 112 to act as a stop, preventing the locking member 20 from accidentally loosening or falling off. The elastic member 25 is at least partially located in the first channel 1111 and is pre-loaded between the limit plate 112 and the screwing head 22. Therefore, when the locking member 20 is in the second state, that is, when the latch 21 is located in the latch groove 312 , the elastic member 25 can provide a downward traction force to perform a locking function.

[0046] When the locking member 20 is in the first position, the main unit 30 can be conveniently placed on the mounting plate 11, ready for securement. The latch 21 is positioned within the sliding channel 311, and the elastic member 25 remains preloaded. The operator rotates the screw end 22, driving the rotation shaft 23 and the latch 21. As the latch 21 gradually approaches the slot 312, the traction of the elastic member 25 begins to take effect, helping the latch 21 to smoothly enter the slot 312. When the latch 21 is fully inserted into the slot 312, the locking member 20 reaches the second position, and the main unit 30 is securely fixed to the mounting plate 11.

[0047] When the main unit 30 needs to be disassembled, the operator rotates the screw end 22 in the opposite direction to drive the latch 21 to withdraw from the slot 312 and return to the sliding channel 311. At this time, the locking member 20 returns to the first state, and the main unit 30 can be easily removed from the mounting plate 11.

[0048] The screwing end 22 includes a connected screwing portion 221 and a boss 222. The screwing portion 221 is designed to be rotated or twisted. The screwing portion 221 may have threads, grooves, or other features that facilitate gripping and rotation by hand or with a tool. The vertical projection of the screwing portion 221 is at least partially located outside the first channel 1111. In other words, the outer dimensions of the screwing portion 221 are equal to the dimensions of the first channel 1111. This ensures that the screwing portion 221 remains exposed in the first channel 1111, thereby allowing the screwing portion 221 to be accessed or operated from the outside.

[0049] Regardless of whether the locking member 20 is in the first state or the second state, the boss 222 always remains at least partially located in the first channel 1111, one end of the elastic member 25 abuts against an end surface of the boss 222 away from the screwing portion 221, and the other end of the elastic member 25 abuts against the limiting plate 112, thereby limiting the elastic member 25 in the first channel 1111 to prevent the spring from being displaced or falling off during use.

[0050] The elastic member 25 can be a spring, which is sleeved on the rotating shaft 23 to prevent the spring from loosening or falling off due to vibration or rotation, and to limit the spring from deforming along the axial direction of the rotating shaft 23, thereby preventing the spring from twisting or bending unnecessarily and causing insufficient locking force on the main unit 30 and the mounting plate 11.

[0051] In one embodiment, the screwing end 22 is detachably connected to the rotating shaft 23. When installing the locking member 20, the rotating shaft 23, with the bayonet 21 and the stop plate 24 fixed thereto, can be passed from top to bottom through the third passage 1121. The stop plate 24 is restrained by the stop plate 112, preventing the rotating shaft 23 from completely passing through the stop plate 112 and falling. The screwing end 22 is then connected to the rotating shaft 23 at the second portion exposed below the first passage 1111.

[0052] Based on the above embodiment, a mounting groove 223 is provided on the screwing end 22. Specifically, a mounting groove 223 is provided on one end surface of the boss 222 away from the screwing portion 221. The rotating shaft 23 is inserted into the mounting groove 223, and the screwing end 22 and the rotating shaft 23 are connected by fasteners.

[0053] The cross-sectional shape of the mounting groove 223 is non-rotating to ensure effective torque transmission between the screwing end 22 and the rotating shaft 23. The cross-sectional shape of the mounting groove 223 can be regular or irregular, such as semicircular, arc-shaped, or polygonal. The cross-sectional shape of the lower portion of the rotating shaft 23 matches the cross-sectional shape of the mounting groove 223, but this is not limited in this application. In other embodiments, torque transmission between the screwing end 22 and the rotating shaft 23 can also be achieved through a key connection, latch, or the like.

[0054] The fastener can be a screw, and a threaded hole is provided at the lower end of the rotating shaft 23, and the screw passes through the screwing end 22 and is connected to the rotating shaft 23. In other embodiments, the screwing end 22 and the rotating shaft 23 can also be connected by welding, riveting, etc.

[0055] Please refer to Figures 5 to 7The main unit 30 includes a base plate 32 and a housing 33. The lower edge of the housing 33 is connected to the base plate 32, forming an inner cavity. The laser emitter is mounted on the base plate 32 and located in the inner cavity. The housing 33 protects components installed in the inner cavity, such as the laser generator. The base plate 32 is partially supported on the top surface of the mounting plate 11. The base plate 32 is provided with a clearance 322, and the laser emitter's emission end is positioned opposite the clearance 322. The fixing base 31 can be a part of the base plate 32 or a separate component from the base plate 32. This application does not limit this.

[0056] The base plate 32 typically has sufficient strength and rigidity to prevent deformation or damage during use. The housing 33 is typically made of metal (such as aluminum alloy or steel) or plastic, ensuring sufficient strength and durability. The design of the housing 33 also needs to consider factors such as heat dissipation, dustproofing, and waterproofing to ensure stable operation of the host 30.

[0057] The lower edge of the housing 33 is connected to the base plate 32 by fasteners, such as screws or clips, or other connection methods, such as welding or bonding, so that the housing 33 and the floor form a single integral structure. This ensures a tight seal between the housing 33 and the base plate 32 while also ensuring a secure connection.

[0058] In the first example, the fixing base 31 is directly formed by protruding a portion of the bottom plate 32 into the inner cavity. This design allows the bottom plate 32 and the fixing base 31 to form a single unit, eliminating the need for additional connectors or fasteners. This simplifies the structure while improving the overall stability and reliability of the bottom plate 32 and fixing base 31.

[0059] In the second example, a mounting hole 321 is defined on the base plate 32. The fixing seat 31 is connected to the mounting hole 321, and the locking slot 312 is positioned toward the inner cavity. That is, the fixing seat 31 is positioned within the inner cavity. The housing 33 protects the fixing seat 31, preventing other components from contacting the latch 21 and causing locking failure. Furthermore, the fixing seat 31 and the base plate 32 are separate components, allowing them to be made of different materials. For example, the base plate 32 can be made of lightweight materials such as aluminum alloy or carbon fiber composite materials, thereby reducing the weight of the entire host 30. The fixing seat 31 should be made of wear-resistant materials such as high-carbon steel, stainless steel, alloy steel, hard plastics (such as nylon or polyoxymethylene (POM)), and certain special alloys or composite materials to prevent structural wear on the fixing seat 31 and causing locking failure. The sliding channel 311 on the fixing base 31 communicates with the mounting hole 321 on the base plate 32, providing a path for the latch 21 of the locking member 20 to move freely in the vertical direction, thereby facilitating installation and removal of the main unit 30. The fixing base 31 can be partially disposed within the mounting hole 321, in which case the mounting hole 321 serves only to mount the fixing base 31. Alternatively, the sliding channel 311 can be aligned vertically with the mounting hole 321, so that the sliding channel connects to the mounting hole 321 to form a path for the latch 21 to move.

[0060] The fixing base 31 includes a guide surface 313 connecting the edge of the sliding channel 311 and the locking groove 312. When the latch 21 is located in the sliding channel 311, the locking member 20 is rotated to lift the latch 21 along the guide surface 313 until the latch 21 falls into the locking groove 312, thereby placing the locking member 20 in the second position. Conversely, the latch 21 can also slide along the guide surface 313 into the sliding channel 311, placing the locking member 20 in the first position. The guide surface 313 guides the movement of the latch 21, reducing damage or jamming caused by positional deviation or improper angle.

[0061] The guide surface 313 is an inclined surface, an arc surface or a surface of other shapes used to guide and position the movement of the latch 21, thereby realizing the transition between the sliding channel 311 and the latch groove 312, and allowing the latch 21 to move smoothly along a predetermined track.

[0062] Guide surfaces 313 may be formed on both sides of the locking slot 312 , so that there is no need to distinguish directions when rotating the locking member 20 , thereby improving the convenience of operation.

[0063] See also Figure 7The fixing base 31 includes a base 314 and two support blocks 315. The base 314 connects the fixing base 31 to the bottom plate 32 and connects the two support blocks 315, providing a mounting support foundation for the entire fixing base 31. The two support blocks 315 are arranged opposite each other, forming a sliding channel 311 between them. The top surfaces of the support blocks 315 are formed with a slot 312 and a guide surface 313. The slot 312 is used to receive and secure the detent 21, while the guide surface 313 is used to guide and position the movement of the detent 21, ensuring that the detent 21 can accurately and smoothly enter the slot 312. The bottom of the support block 315 at least partially protrudes from the bottom surface of the base 314. The portion of the support block 315 exposed from the bottom surface of the base 314 extends into the mounting hole 321. In this case, the mounting hole 321 is only used to install the support block 315, and the exposed portion of the support block 315 cooperates with the mounting hole 321 to perform a positioning function.

[0064] The base 314 is connected to the outer walls of the two support blocks 315. Specifically, the base 314 can be considered the flange edge of the support blocks 315, forming a single unit with a clear sliding channel 311. The base 314 not only enhances the overall strength of the base 31, but also makes it easier to install and position the base 31. For example, the base 314 can be connected to the bottom plate 32 using fasteners such as bolts.

[0065] Each of the two support blocks 315 is provided with a slot 312. Correspondingly, the two ends of the bayonet 21 are exposed radially from the outer side of the rotating shaft 23, so that the two ends of the bayonet 21 can be snapped into the two slots 312 one by one. This increases the stability and reliability of the connection and prevents the bayonet 21 from loosening or falling off when subjected to external forces.

[0066] In one embodiment, please refer to Figure 6 and Figure 8 The top surface of the mounting plate 11 is provided with a positioning protrusion 113, and the bottom plate 32 is provided with a positioning groove 323. With the bottom plate 32 partially supported on the top surface of the mounting plate 11, the positioning protrusion 113 engages with the positioning groove 323. This allows for precise positioning of the mounting plate 11 and bottom plate 32 before locking the mounting plate 11 and the main unit 30. Each time the mounting plate 11 is reinstalled, the positioning protrusion 113 and the positioning groove 323 automatically align, eliminating the need for extra time and effort to readjust the position. This improves assembly and disassembly efficiency, reduces problems caused by misalignment, and ensures smooth sliding of the locking member 20 within the sliding channel 311.

[0067] The positioning protrusion 113 can be cylindrical, conical, or other shapes that are easy to locate and engage. There can be multiple positioning protrusions 113, which are spaced apart and arranged at the periphery of the installation channel 111 to facilitate alignment of the locking member 20 with the sliding channel 311.

[0068] In one embodiment, positioning protrusion 113 is square, with mounting channel 111 extending through the center of the protrusion 113. This creates four inclined surfaces around the periphery of channel 111. These four inclined surfaces provide better guidance for positioning protrusion 113 during installation. When base plate 32 approaches mounting plate 11, these inclined surfaces automatically align and slide the base plate 32 into the correct position. The inclined surfaces also reduce friction and resistance during installation, making the installation process smoother.
