[0041] Please refer to the reference. Figures 1 to 10 As shown, this utility model proposes a laser device 100, which is applied to a laser engraving machine. The laser engraving machine includes a body, and the laser device 100 includes a mounting base 1, a first snap-fit component 3, a second snap-fit component 4, and a laser 2. The mounting base 1 is used to mount to the body; the first snap-fit component 3 is connected to the mounting base 1; the laser 2 is connected to the second snap-fit component 4; wherein, one of the first snap-fit component 3 and the second snap-fit component 4 is provided with a slot 41, and the other of the first snap-fit component 3 and the second snap-fit component 4 is provided with a protrusion 31. The slot 41 and the protrusion 31 cooperate to realize the detachable connection between the mounting base 1 and the laser 2.
[0042] In some embodiments of this application, the mounting base 1 is pre-assembled onto the body of the laser engraving machine, and the laser 2 is connected to the mounting base 1 and assembled into the body of the laser engraving machine for use. The mounting base 1 is connected to a first snap-fit member 3, and the laser 2 is connected to a second snap-fit member 4. The mounting base 1 and the laser 2 are connected through the limiting cooperation of the first snap-fit member 3 and the second snap-fit member 4. The first snap-fit member 3 and the second snap-fit member 4 are respectively provided with a snap-fit protrusion 31 and a snap-fit groove 41, and are connected through the snap-fit cooperation of the snap-fit protrusion 31 and the snap-fit groove 41. This allows for a detachable connection between the mounting base 1 and the laser 2, and quick assembly and disassembly of the mounting base 1 and the laser engraving machine body, reducing the difficulty of installing and disassembling the laser 2 and improving the user experience. Users can also change the type of laser output by the laser engraving machine by changing the model of the laser 2 to meet different usage needs.
[0043] Understandably, the first latching member 3 has a latching protrusion 31, and a latching groove 41 is formed opposite to the latching protrusion 31. Similarly, the second latching member 4 has a latching groove 41, and a latching protrusion 31 is formed opposite to the latching groove 41. When the latching protrusion 31 of the first latching member 3 is engaged with the latching groove 41 of the second latching member 4, the latching protrusion 31 of the second latching member 4 is also engaged with the latching groove 41 of the first latching member 3. The first latching member 3 and the second latching member 4 interlock with each other to ensure the connection strength between the mounting base 1 and the laser 2.
[0044] Optionally, multiple sets of the protrusion 31 and the slot 41 can be provided, such as two sets, three sets, four sets, etc., to further improve the connection strength and stability between the mounting base 1 and the laser 2.
[0045] In actual implementation, the mounting base 1 can be connected to the second connector 4 and the laser 2 can be connected to the first connector 3, or the mounting base 1 can be connected to the first connector 3 and the laser 2 can be connected to the second connector 4. No specific limitation is made here.
[0046] Optionally, the first snap-fit connector 3 or the second snap-fit connector 4 can be mounted on the mounting base 1 or the laser 2 by means of rotational connection or sliding connection.
[0047] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the laser device 100 also includes a rotating shaft 11, which is fixed to the mounting base 1. The first snap-fit member 3 is provided with a shaft hole 32, and the rotating shaft 11 is at least partially located in the shaft hole 32, so that the first snap-fit member 3 is rotatably connected to the mounting base 1.
[0048] In this embodiment, the first snap-fit member 3 achieves a rotatable connection with the mounting base 1 through the hole-shaft cooperation of the rotating shaft 11 and the shaft hole 32.
[0049] When connecting the laser 2 and the mounting base 1, the user can first rotate the first locking member 3 around the pivot 11, then move the laser 2 towards the mounting base 1, and position the second locking member 4 in the original position corresponding to the first locking member 3. Then, the first locking member 3 is rotated back to its original position so that the locking protrusion 31 of the first locking member 3 engages with the locking groove 41 of the second locking member 4. Correspondingly, when disassembling the laser 2, the user can rotate the first locking member 3 around the pivot 11 so that the locking protrusion 31 of the first locking member 3 is pulled out of the locking groove 41 of the second locking member 4, and then the laser 2 and the mounting base 1 are relatively separated.
[0050] Understandably, the rotational design of the first latching member 3 allows the latching protrusion 31 on the first latching member 3 to directly engage or disengage from the slot 41 of the second latching member 4. This reduces interference between the latching protrusion 31 and the surrounding structure of the slot 41 during the engagement process, lowers the resistance between the first latching member 3 and the second latching member 4, and improves the ease of user operation. Specifically, during the connection process between the laser 2 and the mounting base 1, the laser 2 moves closer to the mounting base 1 along the first direction, and the slot 41 of the second latching member 4 faces the second direction, which forms an angle with the first direction. Thus, when the latching protrusion 31 of the first latching member 3 engages with the slot 41 of the second latching member 4, the laser 2 can be limited in the first direction. When the laser 2 approaches the mounting base 1, the first locking member 3 rotates around the rotating shaft 11 to leave its original position in order to avoid interfering with the movement of the laser 2. When the laser 2 moves into place, the first locking member 3 rotates to reset and the locking protrusion 31 is approximately locked into the slot 41 of the second locking member 4 along the second direction.
[0051] In actual implementation, when the first snap-fit component 3 is in its original position, it extends along the first direction, and the second snap-fit component 4 also extends along the first direction, with the second direction being perpendicular to the first direction.
[0052] Alternatively, the first snap-fit member 3 may be provided with a rotating shaft 11, and the mounting base 1 may be provided with a shaft hole 32 for rotating and limiting the rotating shaft 11.
[0053] Optionally, an elastic element 7 can be provided between the first snap-fit 3 and the mounting base 1 so that the first snap-fit 3 has an automatic reset function.
[0054] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the laser device 100 also includes an elastic element 7, one end of which is connected to the first snap-fit element 3, and the other end of which is connected to the mounting base 1.
[0055] In this embodiment, the elastic element 7 enables the first locking member 3 to have an automatic reset function. During the connection of the laser 2 and the mounting base 1, the user rotates the first locking member 3 around the pivot 11, causing the elastic element 7 to deform and move the laser 2 into place. The slot 41 of the second locking member 4 corresponds to the protrusion 31 of the first locking member 3. When the user removes the external force, the elastic element 7 rebounds, causing the first locking member 3 to reset. The protrusion 31 then engages with the slot 41, keeping the first locking member 3 in a locked state. This improves the connection strength and stability between the laser 2 and the mounting base 1.
[0056] Optionally, the elastic element 7 includes multiple elastic elements 7, which are evenly disposed between the first snap-fit element 3 and the mounting base 1. This ensures that the first snap-fit element 3 has sufficient fastening force, preventing the first snap-fit element 3 from dislodging from the slot 41 of the second snap-fit element 4. At the same time, it also ensures that the first snap-fit element 3 is subjected to uniform force, improving the stability of the snap-fit engagement between the first snap-fit element 3 and the second snap-fit element 4.
[0057] Optionally, the elastic element 7 can be a torsion spring. The rotating shaft 11 and the first locking member 3 can be elastically connected through the torsion spring. The torsion spring is sleeved on the rotating shaft 11, with one end connected to the first locking member 3 and the other end connected to the mounting base 1. When there is no external force applied to the first locking member 3, it is in the engaged position. When connecting the laser 2 and the mounting base 1, the user rotates and lifts the first locking member 3, causing the torsion spring to deform. Then, the slot 41 of the second locking member 4 is aligned with the protrusion 31 of the first locking member 3. When the user removes the external force, the torsion spring rebounds, causing the first locking member 3 to reset, and the protrusion 31 snaps into the slot 41, keeping the first locking member 3 in the engaged state. This improves the ease of connecting the laser 2 and the mounting base 1, and also helps to ensure the stability of the connection between the laser 2 and the mounting base 1.
[0058] In one embodiment of this utility model, such as Figures 1 to 4 As shown, the laser device 100 includes a driving member 5 and a locking member 6. The driving member 5 is connected to the mounting base 1, and the locking member 6 is connected to the output end of the driving member 5. The driving member 5 is used to drive the locking member 6 to move so that the locking member 6 has a first state and a second state. The first state is used to lock the mounting base 1 and the laser 2, and the second state is used to release the mounting base 1 and the laser 2.
[0059] In this embodiment, before the laser 2 and the mounting base 1 are connected, the locking member 6 is in the second state to avoid interfering with the connection between the laser 2 and the mounting base 1. After the laser 2 is connected, the driving member 5 drives the locking member 6 from the second state to the first state, locking the relative positions of the laser 2 and the mounting base 1. This prevents the first locking member 3 and the second locking member 4 from failing to engage due to external force or misoperation, thus preventing the laser 2 from detaching from the mounting base 1 and improving the safety and reliability of the laser 2 during use. Before disassembling the laser 2, the driving member 5 drives the locking member 6 from the first state to the second state to release the lock on the relative positions of the laser 2 and the mounting base 1, after which the laser 2 and the mounting base 1 can be normally separated.
[0060] Optionally, the driving element 5 and the locking element 6 can be disposed on the mounting base 1. After the laser 2 is connected to the mounting base 1, the relative position of the laser 2 and the mounting base 1 is locked by locking the laser 2. Alternatively, the driving element 5 and the locking element 6 can be disposed on the laser 2. After the laser 2 is connected to the mounting base 1, the relative position of the laser 2 and the mounting base 1 is locked by locking the mounting base 1.
[0061] Taking the example of the driving component 5 and the locking component 6 being located in the mounting base 1, the laser 2 moves relative to the mounting base 1 along a first direction for connection or disassembly operations. The laser 2 is provided with a locking hole 33 extending along a third direction, which is set at an angle to the first direction. The locking component 6 can lock the position of the laser 2 by engaging with the locking hole 33. It can be understood that the locking hole 33 can also be located in the first latching component 3. When the first latching component 3 and the second latching component 4 are engaged, the driving component 5 drives the locking component 6 to move, and the driving component 5 drives the locking component 6 to insert into the locking hole 33 to lock the position of the first latching component 3. The first latching component 3 and the second latching component 4 remain engaged, thereby indirectly locking the position of the laser 2 and preventing the laser 2 from separating from the mounting base 1.
[0062] Optionally, the driving component 5 is a linear drive motor, and the locking component 6 is arranged in a rod-like or block-like form. In actual implementation, the user can control the driving component 5 to drive the locking component 6 through an electronic control button or other electronic control method, thereby switching the locking component 6 between a first state and a second state.
[0063] Optionally, the driving component 5 and the locking component 6 can be electromagnets, and the laser 2 is equipped with a magnetic component. When the proximity sensor sends a positioning signal to the locking component, the electromagnet attracts the magnetic component to lock the position of the laser 2. When it is necessary to disassemble the laser 2, the user can control the electromagnet to lose its magnetism through the electronic control button so that it no longer attracts the magnetic component, thereby unlocking the laser 2 and the mounting base 1.
[0064] In one embodiment of this utility model, such as Figures 1 to 4 As shown, the mounting base 1 is provided with a mounting groove 12, and the first snap-fit 3 is provided in the mounting groove 12. The first snap-fit 3 and the groove wall of the mounting groove 12 cooperate to limit the second snap-fit 4.
[0065] In this embodiment, when the laser 2 and the mounting base 1 are connected, the second snap-fit member 4 is inserted into the mounting groove 12, and the snap-fit protrusion 31 of the first snap-fit member 3 is engaged into the snap-fit groove 41 of the second snap-fit member 4 to prevent the second snap-fit member 4 from coming out of the mounting groove 12. The groove wall of the mounting groove 12 abuts against the side wall of the second snap-fit member 4 to limit its movement and prevent it from shaking in the mounting groove 12, thereby ensuring the stability of the connection between the laser 2 and the mounting base 1.
[0066] Optionally, the first snap-fit member 3 is disposed within the mounting groove 12 and serves as one side wall of the mounting groove 12. When the laser 2 and the mounting base 1 are connected in place, the second snap-fit member 4 is inserted into the mounting groove 12 from the opening of the mounting groove 12. The first snap-fit member 3 and the groove wall of the mounting groove 12 together limit the second snap-fit member 4, preventing the second snap-fit member 4 from moving in a direction perpendicular to the axial direction of the mounting groove 12. At the same time, the snap-fit engagement of the first snap-fit member 3 and the second snap-fit member 4 restricts the second snap-fit member 4 from moving along the axial direction of the mounting groove 12, thereby fixing the spatial position of the second snap-fit member 4, and the position of the laser 2 connected to the second snap-fit member 4 is also fixed. It can be understood that the laser 2 moves relative to the mounting base 1 in a first direction for connection or disassembly, and the axial direction of the mounting groove 12 is set in the first direction so that the second snap-fit member 4 can be inserted into or removed from the mounting groove 12 as the laser 2 moves.
[0067] Optionally, the surface of the first snap-fit 3 facing away from the mounting groove 12 is flush with the outer wall of the mounting base 1 to ensure the flatness of the appearance of the mounting base 1 and the first snap-fit 3 as much as possible, so as to facilitate the assembly of the mounting base 1.
[0068] Optionally, the mounting groove 12 is located near the edge of the mounting base 1 to avoid other electrical or mechanical structures on the mounting base 1.
[0069] In one embodiment, the driving member 5 and the locking member 6 are mounted on the mounting base 1, and the laser 2 is locked by locking the first snap-fit member 3. The mounting base 1 is also provided with a mounting position 16 for mounting the driving member 5 and the locking member 6 near the mounting groove 12. The mounting position 16 may also be groove-shaped or a sub-cavity 211. The driving member 5 and the locking member 6 are mounted at the mounting position 16, and the mounting position 16 communicates with the mounting groove 12 so that the locking member 6 can extend into the mounting groove 12 to lock the first snap-fit member 3. Optionally, the locking hole 33 is provided on the side of the snap protrusion 31 to reduce the impact of the locking hole 33 on the structural strength of the first snap-fit member 3.
[0070] In one embodiment of this utility model, such as Figures 1 to 4 As shown, a protrusion is provided between the mounting base 1 and the laser 2, and a circuit board switch 8 is provided between the mounting base 1 and the laser 2. The disconnection between the mounting base 1 and the laser 2 enables the protrusion to open and close the circuit board switch 8.
[0071] In this embodiment, the circuit board switch 8 is used to determine whether the laser 2 and the mounting base 1 are properly connected. When the mounting base 1 and the laser 2 are properly connected, the protrusion triggers the circuit board switch 8, which then alerts the user that the laser 2 and the mounting base 1 are in a normal connection state. However, during the use of the laser 2, if the laser 2 is accidentally displaced, causing the protrusion to no longer trigger the circuit board switch 8, the user can be alerted that the laser 2 and the mounting base 1 are in an abnormal connection state, prompting the user to troubleshoot promptly and ensure the installation safety of the laser 2.
[0072] In actual implementation, the circuit board switch 8 can be mounted on the mounting base 1 and the protrusion can be mounted on the laser 2, or the circuit board switch 8 can be mounted on the laser 2 and the protrusion can be mounted on the mounting base 1.
[0073] Optionally, the laser device 100 also includes an indicator light electrically connected to the circuit board switch 8. By observing the color of the indicator light, such as green when the circuit board switch 8 is triggered and red when the circuit board switch 8 is not triggered, the user can know whether the mounting base 1 and the laser 2 are in a normal connection state.
[0074] Optionally, the circuit board switch 8 can be a non-contact sensor such as a photoelectric sensor or an electromagnetic sensor, or it can be a contact sensor; no specific limitation is made here.
[0075] In one embodiment, the circuit board switch 8 and the drive unit 5 are electrically connected. Taking an example where the circuit board switch 8, drive unit 5, and locking unit 6 are mounted on the mounting base 1, the circuit board switch 8 on the mounting base 1 senses the protrusion of the laser 2 and sends a connection signal to the drive unit 5. The drive unit 5 automatically moves the laser 2 from a second state to a first state, thereby locking the relative position of the laser 2 and the mounting base 1. This achieves automatic locking installation of the laser 2, greatly ensuring the installation reliability of the laser 2.
[0076] In one embodiment of this utility model, such as Figures 1 to 4 As shown, the mounting base 1 has a mounting surface 13 and a through hole through the mounting surface 13. The mounting surface 13 is used for the laser 2 to abut against, and the circuit board switch 8 is located in the through hole.
[0077] In this embodiment, when the laser 2 is installed in place, the end face of the laser 2 abuts against the mounting surface 13 of the mounting base 1, triggering the circuit board switch 8 inside the through hole. The circuit board switch 8 is disposed inside the through hole to avoid obstructing the laser 2 and prevent the laser 2 from colliding with the circuit board switch 8, thus affecting the service life of the circuit board switch 8.
[0078] In actual implementation, the circuit board switch 8 is mounted on the circuit board, which is located on the side of the mounting base 1 facing away from the mounting surface 13. A through hole is provided through the mounting base 1 so that the proximity switch can detect the laser 2 on the other side through the through hole.
[0079] In one embodiment of this utility model, as shown in Figures 1 and 2, a positioning shaft 26 is provided between the mounting base 1 and the laser 2, and a positioning hole 15 is provided between the mounting base 1 and the laser 2. When the mounting base 1 and the laser 2 are connected, the positioning shaft 26 is at least partially located in the positioning hole 15.
[0080] In this embodiment, when assembling the laser 2 and the mounting base 1, the cooperation of the positioning shaft 26 and the positioning hole 15 facilitates the positioning and installation of the laser 2 and the mounting base 1, while enhancing the stability of the connection between the laser 2 and the mounting base 1 and preventing the relative positions of the laser 2 and the mounting base 1 from shifting.
[0081] Optionally, the mounting base 1 is also provided with a mounting hole 14 for the laser head of the laser 2 to pass through. A handle is provided on the side of the laser 2 facing away from the mounting surface 13, allowing the user to move the laser 2. The handle can be equipped with a first magnet, and the laser 2 can be equipped with a second magnet. The mutual attraction between the first and second magnets can fix the position of the handle, preventing it from shaking.
[0082] In one embodiment of this utility model, such as Figures 5 to 8 As shown, the laser 2 includes a housing 21, a laser generating module 22, an electronic control module 23, and a heat sink 24. The housing 21 defines a cavity 211, and the heat sink 24 is disposed in the cavity 211 to divide the cavity 211 into a first sub-cavity 2111 and a second sub-cavity 2112. The laser generating module 22 is disposed in the first sub-cavity 2111, and the electronic control module 23 is disposed in the second sub-cavity 2112.
[0083] In this embodiment, the laser generating module 22 is used to generate laser light, and the electronic control module 23 is used to control the operation of the laser generating module 22. The outer shell 21 encloses and forms a cavity 211. The heat sink 24 disposed in the cavity 211 divides the cavity 211 into a first sub-cavity 2111 and a second sub-cavity 2112. The laser generating module 22 and the electronic control module 23 are respectively disposed in the first sub-cavity 2111 and the second sub-cavity 2112. In this way, the electronic control module 23 and the laser generating module 22 can be set separately, avoiding the heat generated by the laser generating module 22 from affecting the normal operation and service life of the electronic control module 23. At the same time, it makes the structure of the laser 2 more compact and reduces the size of the laser 2, so as to facilitate the installation of the laser 2.
[0084] In this embodiment, the heat sink 24 is provided with a heat dissipation cavity 2411, the laser generating module 22 is disposed in the heat dissipation cavity 2411, the heat dissipation cavity 2411 forms a first sub-cavity 2111, the wall of the heat sink 24 away from the heat dissipation cavity 2411 and the shell surrounds to form a second sub-cavity 2112, and the electronic control module 23 is attached to the heat sink 24 and located in the second sub-cavity 2112.
[0085] Optionally, the electronic control module 23 can be detachably mounted to the heat sink 24 by means of screws or clips.
[0086] Optionally, the heat sink 24 includes a heat sink shell 241 that encloses a heat sink cavity 2411 and heat sink fins 242 connected to the plate body. The heat sink cavity 2411 is enclosed by the heat sink shell 241 to ensure the sealing of the first sub-cavity 2111. The heat sink fins 242 are connected to the heat sink shell 241 and are arranged in multiple spaced intervals to increase the heat dissipation area of the heat sink 24. Both the heat sink shell 241 and the heat sink fins 242 are made of thermally conductive materials and can be integrally formed. A heat sink plate 243 is connected to the side of the heat sink fins 242 away from the heat sink shell 241, and the circuit module is connected to the heat sink plate 243. In one embodiment, the heat sink shell 241 encloses a heat sink groove, and a heat sink cover 244 covers the opening of the heat sink groove to enclose the heat sink cavity 2411 with the heat sink shell 241. A sealing ring is provided between the heat sink cover 244 and the heat sink shell 241.
[0087] In actual implementation, such as Figures 7 to 9 As shown, the laser generation module 22 includes pump source A221, pump source B222, pump source C223, doped fiber 224, and Q switch 225 (giant pulse generator). Pump source A221 provides a seed source for the oscillation stage, generating laser light through photoelectric conversion. Pump sources B222 and C223 amplify the pulse signal generated by the seed source. The pulse can achieve energy level transitions and rapid adjustment of the resonant cavity Q value through the high-reflection grating doped fiber 224, low-reflection grating, and Q switch 225 to achieve high peak power pulse output. Optionally, pump sources A221, B222, C223, and Q switch 225 can be detachably connected to the heat sink 24 using screws or clips, and the doped fiber 224 can be connected to the heat sink 24 by adhesive bonding.
[0088] In practical implementation, the laser 2 also includes a fan 25 connected to a heat sink 242. A guide groove is provided between adjacent heat sinks 242 to reduce the air resistance of the fan 25 and improve the cooling effect on the heat sink 24. The outer casing 21 has ventilation openings through which the fan 25 facilitates heat exchange between the heat sink 24 and the outside, accelerating the cooling efficiency of the heat sink 24 and thus improving its cooling effect. The outer casing 21 also has wiring holes for connecting the power control module 23 to the outside. These holes can be sealed with adhesive to ensure the airtightness of the second sub-cavity 2112. The power control module 23 is coated with conformal coating to prevent water vapor and impurities from affecting its circuitry. The surface of the heat sink 24 can be anodized to improve its radiation performance and effectively enhance its heat dissipation capacity.
[0089] In one embodiment of this utility model, such as Figure 9 and Figure 10As shown, the laser 2 includes an isolator assembly 9, which includes a lens barrel 91. The lens barrel 91 defines a cavity 911. An isolator 92 is disposed inside the cavity 911, and at least one of a beam expander and a protective lens 93 is disposed inside the cavity 911.
[0090] In this embodiment, the isolator 92 functions based on the Faraday effect, using a combination of a polarizer and a Faraday rotator to achieve unidirectional light transmission (forward transmittance >90%, reverse isolation >40dB), thus preventing back-reflected light from damaging the pump source inside the laser 2. The isolator assembly 9 is located at the output end of the laser generation module 22.
[0091] In practical implementation, a beam expander or a protective lens 93, or both, can be installed inside the lens barrel 91. The beam expander is used to adjust the diameter of the collimated spot, and the protective lens 93 prevents dust or impurities from falling into the lens barrel 91. By integrating the beam expanders into the isolator assembly 9, there is no need to place a separate beam expander between the isolator 92 and the galvanometer, which greatly reduces the distance between the isolator 92 and the galvanometer and does not occupy the space of the cavity 211. Understandably, the protective lens 93 is located at the output end of the isolator assembly 9. When the lens of the isolator assembly 9 is contaminated, it can be reused simply by replacing the removable protective lens 93, greatly reducing operating costs.
[0092] In actual implementation, the heat sink 24 is provided with a through hole for the lens barrel 91 to pass through. The lens barrel 91 can be connected to the heat sink 24 by screws. The outer shell 21 is also provided with a fixing hole for the lens barrel 91 to pass through, so as to transmit the laser to the outside of the outer shell 21 and realize laser output. A sealing ring is provided in the fixing hole to ensure the sealing of the outer shell 21 at the fixing hole.
[0093] In one embodiment of this utility model, the protective mirror 93 is detachably disposed at one end of the cylindrical cavity 911 near the mounting base 1 to prevent dust or impurities from entering the laser generating module 22, while also facilitating user disassembly and assembly of the protective mirror 93. The protective mirror 93 and the mirror cylinder 91 can be detachably connected by means of threaded engagement or snap-fit structure.
[0094] In one embodiment of this utility model, such as Figure 1 As shown, the mounting base 1 has a mounting hole 14, and a galvanometer and a field lens are mounted in the mounting hole 14. When the mounting base 1 is assembled to the main body, the galvanometer and the field lens are also assembled to the main body. The galvanometer and the field lens can be adapted to different types of lasers 2, such as red lasers 2 or blue lasers 2, etc.
[0095] In this embodiment, the mounting hole 14 of the mounting base 1 is used for the laser head of the laser 2 to pass through. A galvanometer and a field lens are mounted in the mounting hole 14. The galvanometer is used to adjust the emission direction of the laser emitted from the laser 2 to achieve scanning processing. The field lens is used to adjust the focal point of the laser emission so that the laser is focused on the processing plane. The laser emitted from the laser 2 is first reflected by the galvanometer and then emitted onto the processing plane through the field lens. The cooperation of the galvanometer and the field lens enables laser scanning processing and can be adjusted according to the workpiece to change the laser's focusing position and focused spot size, achieving optimal processing results.
