[0051] The following embodiments of this application will be described in conjunction with the accompanying drawings.
[0052] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" means that the two parts are connected and their relative positional relationship remains unchanged after connection. "Rotary connection" means that the two parts are connected and can rotate relative to each other after connection. "Sliding connection" means that the two parts are connected and can slide relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "inner" and "side," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or mirror referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.
[0053] Furthermore, the mathematical concepts mentioned in the embodiments of this application, such as parallel and perpendicular, are limitations specific to the current technological level, rather than absolute and strict mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between A and B ranging from 0 to 10 degrees. "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between A and B ranging from 80 to 100 degrees.
[0054] Figure 1 This is a schematic diagram of the structure of an optical path device 1000 provided in this application.
[0055] like Figure 1 As shown, the optical path device 1000 includes a first base 101, an emitting component 200, a first dimming component 300, a second dimming component 400, and a focusing component 500. For ease of description, exemplarily, the length direction of the first base 101 is defined as the X-axis direction, the width direction of the first base 101 as the Y-axis direction, and the height direction of the first base 101 as the Z-axis direction. In this embodiment, the Y-axis direction is taken as the first direction, the X-axis direction as the second direction, and the Z-axis direction as the third direction. Thus, the second direction can intersect the first direction, and the third direction intersects the second direction and can also intersect the first direction. Specifically, the first direction, the second direction, and the third direction can be perpendicular to each other. In other embodiments, the coordinate system of the optical path device 1000 can also be flexibly set according to specific needs. In this case, the first direction, the second direction, and the third direction can be flexibly set according to specific needs.
[0056] like Figure 1As shown, the emitting component 200 is mounted on the first base 101. The emitting component 200, the first dimming component 300, and the second dimming component 400 can be located in the XY plane. The first dimming component 300 and the second dimming component 400 can be arranged along the X-axis. The second dimming component 400 and the focusing component 500 can be arranged along the Z-axis. The emitting component 200 emits a laser beam, which passes sequentially through the first dimming component 300, the second dimming component 400, and the focusing component 500 to form a processing beam that reaches the workpiece, enabling processing of the workpiece (e.g., engraving, cutting, etc.).
[0057] This application arranges the second dimming component 400 and the focusing component 500 along the Z-axis, enabling the laser emitted by the emitting component 200 in the XY plane to process a workpiece located in the Z-axis direction. The optical path device 1000 and the workpiece can be arranged along the Z-axis. This results in two advantages: firstly, the optical path device 1000 has a compact structure, occupying little space in the Z-axis direction, which is beneficial for miniaturization; secondly, the size and shape of the workpiece are not limited by the optical path device 1000, thus broadening its application range.
[0058] Figure 2 yes Figure 1 A magnified view of the optical path device 1000 at point A.
[0059] like Figure 1 and Figure 2 As shown, the emitting assembly 200 may include a first laser 21, a second laser 22, a third dimming assembly 23, a fourth dimming assembly 24, and a driving assembly. The first laser 21 is fixed to the first base 101 and can be used to emit a first laser beam. The third dimming assembly 23 can be used to reflect the first laser beam to form a first light beam. The second laser 22 is fixed to the first base 101 and can be used to emit a second laser beam. The fourth dimming assembly 24 can be used to reflect the second laser beam to form the first light beam.
[0060] This application incorporates a third reflector 231 and a fourth reflector 241. The third reflector 231 reflects a first laser beam along the Y-axis, and the fourth reflector 241 reflects a second laser beam along the Y-axis, allowing the first and second laser beams to combine. It is understood that the optical path device 1000 can be applied to laser processing equipment. Laser processing equipment has a compact structure and occupies little space; furthermore, it can utilize the optical path device 1000 to process workpieces of various sizes and shapes, thus having a wide range of applications.
[0061] In this embodiment, the wavelength of the second laser beam is different from that of the first laser beam. Thus, the optical path device 1000 can use lasers of different wavelengths to process the workpiece as needed.
[0062] For example, the first laser 21 can be a Q-switched laser for emitting a short-wavelength first laser beam. The wavelength of the first laser beam is in the range of 100-2000 nanometers, for example, the wavelength of the first laser beam can be 1064 nanometers. The second laser 22 can be a carbon dioxide laser for emitting an ultra-long-wavelength second laser beam. The wavelength of the second laser beam is in the range of 10-20 micrometers, for example, the wavelength of the second laser beam can be 10.6 micrometers.
[0063] The first laser 21 of this application can be used to emit short-wavelength lasers, and the second laser 22 can be used to emit ultra-long-wavelength lasers, so that the optical path device 1000 can be used to process different materials, such as metals and non-metals.
[0064] In other embodiments, the first laser 21 can be used to emit a second laser beam with an ultra-long wavelength, and the second laser 22 can be used to emit a first laser beam with a short wavelength.
[0065] For example, the first laser 21 and the second laser 22 can be staggered in the Y-axis direction. In this way, the first laser beam and the second laser beam can be staggered in the Y-axis direction.
[0066] For example, the first laser 21 and the second laser 22 can be arranged in parallel. The first laser beam can be parallel to the second laser beam.
[0067] In this embodiment, the first laser 21 and the second laser 22 operate at staggered times. When the third dimming component 23 and the fourth dimming component 24 are staggered in the X-axis direction, and the third dimming component 23 is positioned opposite to the first dimming component 300, the first laser 21 can be in an active state, and the second laser 22 can be in a deactivated state. Alternatively, the third dimming component 23 and the fourth dimming component 24 can overlap in the X-axis direction, and the fourth dimming component 24 is positioned opposite to the first dimming component 300. In this case, the second laser 22 can be in an active state, and the first laser 21 can be in a deactivated state.
[0068] Figure 3 yes Figure 1 A partial optical path diagram of the optical path device 1000 shown.
[0069] like Figure 2 and Figure 3As shown, the third dimming assembly 23 includes a third reflector 231 for reflecting the first laser line. The fourth dimming assembly 24 includes a fourth reflector 241 for reflecting the second laser line. The focusing assembly 500 includes a focusing lens 51.
[0070] When the first laser 21 operates, it emits a first laser beam along the negative X-axis to the third reflecting mirror 231, which then reflects the first laser beam along the positive Y-axis to form a first ray. It can be understood that the propagation direction of the first laser beam can be parallel to the X-axis. The propagation direction of the first ray can also be parallel to the Y-axis.
[0071] The first dimming assembly 300 includes a first reflector 31 for reflecting a first light ray. The first reflector 31 can reflect the first light ray in the positive direction of the X-axis to form a second light ray. It is understood that the propagation direction of the second light ray can be parallel to the X-axis direction. The second dimming assembly 400 includes a second reflector 41 for reflecting the second light ray. The second reflector 41 can reflect the second light ray in the negative direction of the Z-axis to form a third light ray. It is understood that the propagation direction of the third light ray can be parallel to the Z-axis direction. The focusing assembly 500 includes a focusing lens 51 for focusing the third light ray to form a processing light ray. It is understood that the propagation direction of the processing light ray can be parallel to the Z-axis direction.
[0072] Figure 4 yes Figure 1 The diagram shows the structure of the optical path device 1000 in different states. Figure 5 yes Figure 4 A magnified view of the optical path device 1000 at point B. Figure 6 yes Figure 4 A partial optical path diagram of the optical path device 1000 shown.
[0073] like Figures 4 to 6 As shown, the first dimming component 300 and the second dimming component 400 coincide in the Y-axis direction. The fourth dimming component 24 is disposed opposite to the first dimming component 300. At this time, the second laser 22 can be in the working state. The first laser 21 can be in the off state.
[0074] When the second laser 22 is operational, the first laser 21 can emit a second laser beam along the negative X-axis to the fourth reflector 241, which can then reflect the second laser beam along the positive Y-axis to form a first laser beam. It is understood that the propagation direction of the second laser beam can be parallel to the X-axis, and the propagation direction of the first laser beam can be parallel to the Y-axis.
[0075] The first reflecting mirror 31 reflects a first ray along the positive X-axis to form a second ray. It is understood that the propagation direction of the second ray can be parallel to the X-axis. The second reflecting mirror 41 reflects the second ray along the negative Z-axis to form a third ray. It is understood that the propagation direction of the third ray can be parallel to the Z-axis. The focusing assembly 500 includes a focusing mirror 51 for focusing the third ray to form a processing ray. It is understood that the propagation direction of the processing ray can be parallel to the Z-axis.
[0076] like Figure 2 and Figure 5 As shown, the optical path device 1000 also includes a first driving component 25. The first driving component 25 can be used to drive the third dimming component 23 or the fourth dimming component 24 to move in the X-axis direction.
[0077] For example, along the Y-axis, the third dimming component 23 is located on the side of the fourth dimming component 24 away from the first dimming component 300. The first drive component 25 can be used to move the fourth dimming component 24 in the X-axis direction.
[0078] In other embodiments, along the Y-axis, the fourth dimming component 24 is located on the side of the third dimming component 23 away from the first dimming component 300. The first drive component 25 can be used to move the third dimming component 23 in the X-axis direction.
[0079] like Figure 2 and Figure 5 As shown, the first driving assembly 25 may include a first motor 251, a first lead screw 252, and a first slider 253. The first motor 251 is located on the side of the fourth dimming assembly 24 away from the second laser 22 and is fixed to the first base 101. The first lead screw 252 is arranged along the X-axis. The first lead screw 252 is located on the side of the first motor 251 closer to the second laser 22 and is connected to the first motor 251. The first motor 251 can drive the first lead screw 252 to rotate. The fourth dimming assembly 24 is fixed to the first slider 253.
[0080] For example, the first slider 253 has a through hole 2531. The through hole 2531 of the first slider 253 can extend along the X-axis direction. The first slider 253 may also have a groove 2532. The opening of the groove 2532 of the first slider 253 faces the negative direction of the Z-axis. The first slider 253 may also have a sensing part 2533.
[0081] like Figure 2 and Figure 5As shown, the first slider 253 is connected to the first lead screw 252. The first lead screw 252 can drive the first slider 253 to move along the X-axis, thereby driving the fourth dimming component 24 to move along the X-axis. Exemplarily, the first lead screw 252 can pass through the through hole 2531 of the first slider 253.
[0082] like Figure 2 and Figure 5 As shown, the first drive assembly 25 may further include a first guide rail 254. The first guide rail 254 is arranged parallel to the first lead screw 252. The first guide rail 254 is fixed to the first base 101.
[0083] For example, the sidewall of the first guide rail 254 has a groove 2541. The first guide rail 254 may have two grooves 2541. The grooves 2541 of the two first guide rails 254 may be arranged opposite to each other.
[0084] like Figure 2 and Figure 5 As shown, the first drive assembly 25 may further include a connecting block 255. The connecting block 255 is fixedly connected to the first slider 253. Exemplarily, the connecting block 255 may at least partially be located within the groove 2532 of the first slider 253 and fixed within the groove 2532 of the first slider 253.
[0085] For example, the connecting block 255 has a groove 2551. The opening of the groove 2551 faces the side of the connecting block 255 that is away from the first slider 253.
[0086] For example, the sidewall of the groove 2551 of the connecting block 255 may have a protrusion 2552.
[0087] like Figure 2 and Figure 5 As shown, the connecting block 255 is slidably connected to the first guide rail 254.
[0088] For example, at least a portion of the first guide rail 254 may be located within the groove 2551 of the connecting block 255. The connecting block 255 may slide relative to the first guide rail 254 in the X-axis direction.
[0089] For example, the protrusion 2552 of the connecting block 255 may at least partially lie within the groove 2541 of the first guide rail 254. In this way, the connection between the connecting block 255 and the first guide rail 254 is more stable.
[0090] In one embodiment, when the number of grooves 2541 of the first guide rail 254 is two, the number of protrusions 2552 of the connecting block 255 can also be two. Each protrusion 2552 of the connecting block 255 corresponds to a groove 2541 of each first guide rail 254. At least a portion of the protrusion 2552 of each connecting block 255 can be located within the groove 2541 of each corresponding first guide rail 254.
[0091] In this embodiment, the first slider 253 is slidably connected to the first guide rail 254 via a connecting block 255, and the first slider 253 can move relative to the first guide rail 254 along the X-axis. That is, the fourth dimming component 24 can move relative to the first guide rail 254 along the X-axis. The first guide rail 254 guides the first slider 253, preventing the first slider 253 and the fourth dimming component 24 from deviating during sliding. The optical path device 1000 can operate according to a predetermined optical path, which helps improve the stability of the processing.
[0092] like Figure 2 and Figure 5 As shown, the first drive assembly 25 may further include a first sensor 256 and a second sensor 257. The first sensor 256 and the second sensor 257 are arranged along the X-axis direction. The first sensor 256 and the second sensor 257 are fixed to the first base 101.
[0093] During the process of the first motor 251 driving the first slider 253 and the fourth dimming component 24 to slide along the X-axis, the sensing part 2533 of the first slider 253 can trigger the first sensor 256 or the second sensor 257 to control the working state of the first motor 251. When the sensing part 2533 of the first slider 253 triggers the first sensor 256, the first motor 251 stops running and can enter a self-locking mode. At this time, the first slider 253 stops sliding, the third dimming component 23 and the fourth dimming component 24 are offset in the X-axis direction, the first laser 21 can be in the working state, and the second laser 22 can be in the off state. When the sensing part 2533 of the first slider 253 triggers the second sensor 257, the motor stops running and can enter a self-locking mode, the first slider 253 stops sliding, the third dimming component 23 and the fourth dimming component 24 coincide in the X-axis direction, the second laser 22 can be in the working state, and the first laser 21 can be in the off state.
[0094] like Figure 2 and Figure 5 As shown, the first drive assembly 25 may further include a limiting plate 258. The limiting plate 258 is located on the side of the first slider 253 away from the motor and is fixed to the first base 101. By providing the limiting plate 258, this application can prevent the first slider 253 from disengaging from the first guide rail 254 during sliding.
[0095] For example, the limiting plate 258 can be disposed opposite to the first lead screw 252, and the first lead screw 252 can pass through the limiting plate 258. In this way, the limiting plate 258 can support the first lead screw 252, and the sliding of the first slider 253 driven by the first guide rail 254 is more stable.
[0096] like Figure 2 and Figure 5 As shown, the first driving assembly 25 may further include an elastic element 259. The elastic element 259 can be sleeved on the first lead screw 252 and located between the first slider 253 and the limiting block. By providing the elastic element 259, when the first slider 253 slides along the positive X-axis, the elastic element 259 is compressed by the first slider 253, generating an elastic force. The elastic element 259 also exerts an elastic force on the first slider 253 in the negative X-axis direction. This avoids direct collision between the first slider 253 and the limiting plate 258, preventing damage.
[0097] For example, the elastic element 259 can be a spring, rubber, etc.
[0098] Figure 7 yes Figure 5 The fourth dimming component 24 shown is a partial cross-sectional view at CC.
[0099] like Figure 7 As shown, the fourth dimming assembly 24 may also include a frame 242, a mounting bracket 243, and a mirror mounting base 244. The mirror mounting base 244 may be fixed to the first slider 253 by adhesive or fasteners (e.g., screws, bolts, or rivets).
[0100] For example, the frame 242 may have a first through hole 2421. The mounting bracket 243 may have a second through hole 2431. The mirror mounting base 244 may have a first opening 2441, a second opening 2442, and a third opening 2443. The first opening 2441, the second opening 2442, and the third opening 2443 are interconnected. The first opening 2441 may extend along the X-axis direction. The third opening 2443 may extend along the Y-axis direction.
[0101] like Figure 2 and Figure 7 As shown, the fourth reflector 241 is mounted on the mirror frame 242. The mounting bracket 243 and the mirror frame 242 are sequentially mounted on the reflector mounting base 244.
[0102] For example, the fourth reflector 241 can be fixed within the first through hole 2421 of the frame 242. The frame 242 can be fixed to the mounting bracket 243 by fasteners (e.g., screws, bolts, or rivets). At least a portion of the reflective surface of the fourth reflector 241 can be exposed relative to the second through hole 2431 of the mounting bracket 243. The mounting bracket 243 can be fixed to the reflector mounting base 244 by adhesive or fasteners (e.g., screws, bolts, or rivets). The second opening 2442 of the mounting base can be arranged opposite to the second through hole 2431 of the mounting bracket 243. At least a portion of the reflective surface of the fourth reflector 241 can face the second opening 2442 of the mounting base. In this way, the reflective surface of the fourth reflector 241 is not exposed, the reflective surface of the fourth reflector 241 is not prone to dust accumulation, and light loss can be reduced. Secondly, the reflective surface of the fourth reflector 241 is not easily damaged by scratches, and the fourth reflector 241 does not need to be replaced frequently.
[0103] In this embodiment, the second laser beam can enter from the first opening 2441, pass through the second opening 2442 to reach the third reflector 231, and after being reflected by the third reflector 231, it can exit from the third opening 2443.
[0104] In one embodiment, the structure of the third dimming component 23 can be referred to. Figure 7 The relevant descriptions are omitted here.
[0105] Figure 8 yes Figure 6 A partial optical path diagram of the optical path device 1000 shown.
[0106] like Figure 8 As shown, the first reflecting mirror 31, the second reflecting mirror 41, and the focusing mirror 51 can move along the Y-axis, allowing the processing light rays of the optical path device 1000 to move along the Y-axis, thus enabling engraving or cutting of the workpiece in the Y-axis direction. The second reflecting mirror 41 and the focusing mirror 51 can also move along the X-axis, allowing the processing light rays of the optical path device 1000 to move along the X-axis, thus enabling engraving or cutting of the workpiece in the X-axis direction. The focusing mirror 51 can also move along the Z-axis, adjusting the focusing position of the third light ray in the Z-axis direction. This allows for changing the processing depth of the workpiece in the Z-axis direction, achieving 3D engraving, and also enables processing of workpieces with inconsistent thickness in the Z-axis direction.
[0107] In this embodiment, the processing ray of the optical path device 1000 can move in the XY plane, so that the optical path device 1000 can not only perform planar processing on the workpiece, but also adjust the focusing position in the Z-axis direction to realize 3D engraving of the workpiece and engraving or cutting of workpieces with uneven thickness in the Z-axis direction.
[0108] Figure 9 yes Figure 1 A partial structural schematic diagram of the optical path device 1000 shown.
[0109] like Figure 8 and Figure 9 As shown, the optical path device 1000 includes a Y-axis drive assembly 600 (i.e., the fourth drive assembly 600). The Y-axis drive assembly 600 is used to drive the first reflector 31, the second reflector 41, and the focusing lens 51 to move in the Y-axis direction.
[0110] Exemplarily, the Y-axis drive assembly 600 further includes a drive component 700, a first Y-axis guide rail 62a (i.e., a fourth guide rail 62a), a first Y-axis synchronous pulley 63a, and a first Y-axis synchronous belt 64a. The first Y-axis guide rail 62a is arranged along the Y-axis direction. The first Y-axis guide rail 62a is fixed to the first base 101. The drive component may include a Y-axis drive motor 70. The Y-axis drive motor 70 and the first Y-axis synchronous pulley 63a are located on opposite sides of the first Y-axis guide rail 62a. The Y-axis drive motor 70 is fixed to the first Y-axis guide rail 62a, and the first Y-axis synchronous pulley 63a is connected to the Y-axis drive motor 70. The Y-axis drive motor 70 is used to drive the first Y-axis synchronous pulley 63a to rotate.
[0111] For example, the Y-axis drive assembly 600 may further include a first Y-axis idler wheel 65. The first Y-axis idler wheel 65 and the first Y-axis synchronous wheel 63a may be located near the two ends of the first Y-axis guide rail 62a and are disposed opposite to each other. The first Y-axis idler wheel 65 is rotatably connected to the first Y-axis guide rail 62a.
[0112] For example, a first Y-axis synchronous belt 64a is sleeved on a first Y-axis synchronous pulley 63a and a first Y-axis idler pulley 65. Rotation of the first Y-axis synchronous pulley 63a can drive the first Y-axis synchronous belt 64a to drive the first Y-axis idler pulley 65 to rotate.
[0113] like Figure 9 As shown, the Y-axis drive assembly 600 also includes a first Y-axis connector 66a, a first Y-axis pulley 67, and a first Y-axis guide shaft 68. The first Y-axis connector 66a can be fixed to the first Y-axis timing belt 64a. The first Y-axis pulley 67 can be fixed to the first Y-axis connector 66a by fasteners (e.g., screws, bolts, or rivets).
[0114] For example, the first Y-axis guide rail 62a has a mounting groove 621. The mounting groove 621 extends along the Y-axis direction. There can be two mounting grooves 621. The two mounting grooves 621 are arranged opposite each other in the Z-axis direction.
[0115] like Figure 9 As shown, the first Y-axis guide shaft 68 can be located between the first Y-axis pulley 67 and the first Y-axis guide rail 62a. The first Y-axis pulley 67 can move relative to the first Y-axis guide shaft 68 along the Y-axis direction, thereby driving the first slider 253 to move along the Y-axis direction. Exemplarily, the first Y-axis guide shaft 68 is arranged along the Y-axis direction. A portion of the first Y-axis guide shaft 68 can be located within the mounting groove 621, and a portion can protrude from the mounting groove 621 in the Z-axis direction. The first Y-axis pulley 67 can be engaged with the portion of the first Y-axis guide shaft 68 protruding from the mounting groove 621.
[0116] In this embodiment, by setting a first Y-axis guide shaft 68, the first Y-axis connector 66a and the first Y-axis pulley 67 can be first assembled onto the first Y-axis guide rail 62a, and then the first Y-axis guide shaft 68 can be guided into the mounting groove 621, making the installation and disassembly of the first Y-axis connector 66a and the first Y-axis pulley 67 more convenient.
[0117] In one embodiment, the number of first Y-axis pulleys 67 can be four. The number of first Y-axis guide shafts 68 can be two. In other embodiments, the number of first Y-axis pulleys 67 and first Y-axis guide shafts 68 can also be set as needed, and this application does not make specific limitations.
[0118] Figure 10 yes Figure 9 The diagram shows a partial structure of the optical path device 1000 at different angles.
[0119] like Figure 10As shown, the Y-axis drive assembly 600 also includes a second Y-axis guide rail 62b (i.e., the fifth guide rail 62b), a second Y-axis synchronous pulley 63b, a second Y-axis synchronous belt 64b, and a second Y-axis connector 66b. The second Y-axis guide rail 62b is disposed opposite to the first Y-axis guide rail 62a and is fixed to the first base 101. The second Y-axis synchronous pulley 63b is mounted on the second Y-axis guide rail 62b and can rotate to drive the second Y-axis synchronous belt 64b. The second Y-axis connector 66b is fixedly connected to the second Y-axis synchronous belt 64b. The second Y-axis connector 66b is slidably connected to the second Y-axis guide rail 62b. The connection method between the second Y-axis guide rail 62b, the second Y-axis synchronous pulley 63b, the second Y-axis synchronous belt 64b, and the second Y-axis connector 66b can be found in the connection method between the first Y-axis guide rail 62a, the first Y-axis synchronous pulley 63a, the first Y-axis synchronous belt 64a, and the first Y-axis connector 66a. Specific details will not be elaborated here.
[0120] like Figure 9 and Figure 10 As shown, the drive unit 700 can also be used to drive the first Y-axis synchronous pulley 63a and the second Y-axis synchronous pulley 63b to rotate synchronously. Exemplarily, the drive unit 700 may also include a coupling 71 and a drive link 72. The coupling 71 can be used to connect the Y-axis drive motor 70 and the drive link 72, so that the drive link 72 can rotate synchronously with the first Y-axis synchronous pulley 63a. The drive link 72 can be connected to the second Y-axis synchronous pulley 63b through a bearing pagoda assembly 73, so that the first Y-axis synchronous pulley 63a and the second Y-axis synchronous pulley 63b rotate synchronously, thereby driving the first Y-axis synchronous belt 64a and the second Y-axis synchronous belt 64b to transmit synchronously, so that the first Y-axis connector 66a and the second Y-axis connector 66b can slide synchronously in the Y-axis direction.
[0121] In other embodiments, the drive link 72 can be fixedly connected to the first Y-axis synchronous pulley 63a and the second Y-axis synchronous pulley 63b. The Y-axis drive motor 70 can be used to drive the drive link 72 to rotate, so that the first Y-axis synchronous pulley 63a and the second Y-axis synchronous pulley 63b rotate synchronously.
[0122] Please see Figure 1 In one embodiment, the optical path device 1000 may further include a second base 102. The second base 102 may be disposed opposite to the first base 101. The first Y-axis guide rail 62a and the second Y-axis guide rail 62b may both be fixed to the second base 102. In this way, the connection between the first Y-axis guide rail 62a and the second Y-axis guide rail 62b is more stable, and the optical path device 1000 has higher stability.
[0123] like Figures 8 to 10As shown, the optical path device 1000 also includes an X-axis drive assembly 800 (i.e., the third drive assembly 800). The X-axis drive assembly 800 includes an X-axis drive motor 81, an X-axis synchronous pulley 83, an X-axis synchronous belt 84, an X-axis idler pulley 85, an X-axis connector 86, and an X-axis guide rail 82 (i.e., the third guide rail 82). The X-axis drive motor 81 drives the X-axis synchronous pulley 83 to rotate. The rotation of the X-axis synchronous pulley 83 drives the X-axis synchronous belt 84 and the X-axis idler pulley 85 to rotate. The X-axis connector 86 is fixedly connected to the X-axis synchronous belt 84. The X-axis guide rail is arranged along the X-axis direction. The X-axis connector 86 is slidably connected to the X-axis guide rail 82. The connection method between the X-axis drive motor 81, X-axis guide rail 82, X-axis synchronous pulley 83, X-axis synchronous belt 84, X-axis idler pulley 85, and X-axis connector 86 can be found in the connection method between the Y-axis drive motor 70, first Y-axis guide rail 62a, first Y-axis synchronous pulley 63a, first Y-axis synchronous belt 64a, first Y-axis idler pulley 65, and first Y-axis connector 66a. Specific details will not be elaborated here.
[0124] like Figures 8 to 10 As shown, the X-axis drive assembly 800 is slidably connected to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b. The X-axis drive assembly 800 can move relative to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b in the Y-axis direction. Specifically, the X-axis guide rail 82 is slidably connected to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b. The X-axis guide rail 82 can move relative to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b in the Y-axis direction. Exemplarily, the X-axis guide rail 82 can be fixed to the first Y-axis guide rail 62a connector and the second Y-axis connector 66b by fasteners (e.g., screws, bolts, or rivets).
[0125] This application, by setting a first Y-axis guide rail 62a and a second Y-axis guide rail 62b, provides two advantages. First, the first Y-axis guide rail 62a and the second Y-axis guide rail 62b guide the X-axis guide rail 82, preventing it from deviating during sliding. This also prevents the first reflecting mirror 31, the second reflecting mirror 41, and the focusing mirror 51 mounted on the X-axis guide rail 82 from deviating. The flying optical path device can operate according to the predetermined optical path, which helps improve processing stability. Second, the first Y-axis guide rail 62a and the second Y-axis guide rail 62b support the X-axis guide rail 82, further improving its stability during sliding.
[0126] like Figures 8 to 10As shown, the second dimming assembly 400 is fixedly connected to the X-axis connector 86. The second dimming assembly 400 can move relative to the X-axis guide rail 82 in the X-axis direction. The second dimming assembly 400 can also move relative to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b in the Y-axis direction. Exemplarily, the second dimming assembly 400 may include a mounting base 42. The mounting base 42 can be secured to the X-axis connector 86 by fasteners (e.g., screws, bolts, or rivets).
[0127] like Figures 8 to 10 As shown, the first dimming assembly 300 is fixedly connected to the X-axis guide rail 82. The first dimming assembly 300 can move relative to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b in the Y-axis direction. Exemplarily, the X-axis drive assembly 800 may also include a fixing member 87. The fixing member 87 of the X-axis drive assembly 800 can be fixed to one end of the X-axis guide rail 82 by fasteners (e.g., screws or bolts). The first dimming assembly 300 can be fixed to the fixing member 87 of the X-axis drive assembly 800.
[0128] Figure 11 yes Figure 10 A magnified view of the optical path device 1000 at point D.
[0129] like Figure 10 and Figure 11 As shown, the optical path device 1000 also includes a Z-axis drive assembly 900 (i.e., a second drive assembly 900). The Z-axis drive assembly 900 includes a Z-axis drive motor 91, a Z-axis lead screw 92, a Z-axis slider 93, and a Z-axis guide rail 94 (i.e., a second guide rail 94).
[0130] The Z-axis drive motor 91 drives the Z-axis lead screw 92 to rotate. The Z-axis lead screw 92 is positioned along the Z-axis direction. The Z-axis slider 93 is connected to the Z-axis lead screw. The Z-axis lead screw 92 can drive the Z-axis slider 93 to move in the Z-axis direction. For details on the connection between the Z-axis slider 93 and the Z-axis lead screw, please refer to the connection method between the first slider 253 and the first lead screw 252. Further details are omitted here.
[0131] Z-axis guide rail 94 is arranged parallel to Z-axis lead screw 92. Z-axis slider 93 is slidably connected to Z-axis guide rail 94. Z-axis slider 93 can slide relative to Z-axis guide rail 82 along the Z-axis direction. That is, focusing component 500 can slide relative to X-axis guide rail 82 along the Z-axis direction. For the connection method between Z-axis slider 93 and Z-axis guide rail 94, please refer to the connection method between connecting block 255 and first guide rail 254. Specific details will not be elaborated here.
[0132] This application incorporates a Z-axis guide rail 94, which guides the Z-axis slider 93, preventing it from deviating during sliding. This also ensures the focusing assembly 500 remains unbiased during sliding, allowing the optical path device to operate along a predetermined optical path, thus improving processing stability.
[0133] like Figure 8 and Figure 11 As shown, the Z-axis drive assembly 900 is slidably connected to the X-axis guide rail 82. The Z-axis drive assembly 900 can move relative to the X-axis guide rail 82 in the X-axis direction. The Z-axis drive assembly 900 can also move relative to the first Y-axis guide rail 62a and the second Y-axis guide rail 62b in the Y-axis direction. Exemplarily, the Z-axis drive motor 91 can be fixed to the mounting base 42. The Z-axis drive assembly 900 may also include a fixing member 95. The Z-axis guide rail 94 can be fixed to the fixing member 95 of the Z-axis drive assembly 900. The fixing member 95 of the Z-axis drive assembly 900 can be fixed to the X-axis connector 86 by fasteners (e.g., screws, bolts, or rivets).
[0134] like Figure 8 and Figure 11 As shown, the focusing assembly 500 is fixedly connected to the Z-axis slider 93. The focusing assembly 500 can move relative to the Z-axis guide rail 94 in the Z-axis direction. The focusing assembly 500 can also move relative to the X-axis guide rail 82 in the X-axis direction. The focusing assembly 500 can also move relative to the Y-axis guide rail in the Y-axis direction. Exemplarily, the focusing assembly 500 also includes a focusing lens holder 52. The focusing lens 51 can be mounted on the focusing lens holder 52. The focusing lens holder 52 can be fixed to the first slider 253 by fasteners (e.g., screws, bolts, or rivets). In this way, the focusing lens 51 can slide relative to the Z-axis guide rail 94 in the Z-axis direction, adjusting the focusing position of the third light beam in the Z-axis direction, thereby changing the processing depth of the workpiece in the Z-axis direction, and enabling the processing of workpieces with different thicknesses in the Z-axis direction.
[0135] The above description is merely a specific implementation of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
