[0038] like Figure 1 and Figure 2 As shown, this embodiment provides an optical engine adjustment mechanism applied to an optical device. The mechanism includes a first adjustment component 2 connected to the main body of the optical device, a second adjustment component 3 connected to the first adjustment component 2, and a third adjustment component 4 connected to the second adjustment component 3. The optical engine 5 of the optical device is connected to the third adjustment component 4. One of the first adjustment component 2, the second adjustment component 3, and the third adjustment component 4 adjusts the displacement of the optical engine 5 in the Z-axis direction, while the other two adjust the angle of the optical axis of the optical engine 5 relative to the Z-axis. This embodiment enables efficient and rapid adjustment and precise positioning of the optical engine 5. In the case where the optical device is a printer, it achieves the adjustment of the height of the optical engine 5 and the adjustment of the horizontality of the optical engine 5 relative to the printing surface. The first adjustment component 2, the second adjustment component 3, and the third adjustment component 4 are relatively independent, and their adjustment methods are more convenient, efficient, and precise. The optical engine 5 can be quickly fine-tuned to its optimal position to achieve precise printing.
[0039] In this embodiment, the first adjustment component 2 adjusts the displacement of the optical engine 5 in the Z-axis direction, and the second adjustment component 3 and the third adjustment component 4 adjust the angle of the optical axis of the optical engine 5 relative to the Z-axis. Alternatively, the second adjustment component 3 can adjust the displacement of the optical engine 5 in the Z-axis direction, and the first adjustment component 2 and the third adjustment component 4 can adjust the angle of the optical axis of the optical engine 5 relative to the Z-axis; or the third adjustment component 4 can adjust the displacement of the optical engine 5 in the Z-axis direction, and the first adjustment component 2 and the second adjustment component 3 can adjust the angle of the optical axis of the optical engine 5 relative to the Z-axis.
[0040] In this embodiment, the first adjustment component 2 includes a first adjustment member 21 slidably connected to the main body of the optical device along the Z-axis and a first locking member 22 that locks the first adjustment member 21 to the main body of the optical device. The second adjustment component 3 includes a second adjustment member 31 rotatably connected to the first adjustment member 21 and a second locking member 32 that locks the second adjustment member 31 to the first adjustment member 21. The rotation center line of the second adjustment member 31 is parallel to the Y-axis. The third adjustment component 4 includes a third adjustment member 41 rotatably connected to the second adjustment member 31 and a third locking member 42 that locks the third adjustment member 41 to the second adjustment member 31. The rotation center line of the third adjustment member 41 is parallel to the X-axis.
[0041] When adjusting the optical engine 5, the height of the optical engine 5 is adjusted by raising and lowering the first adjusting member 21 along the Z-axis and fixing it at a preset height by the first locking member 22. The horizontal horizontality of the optical engine 5 is adjusted by rotating the second adjusting member 31 relative to the first adjusting member 21 around the Y-axis and fixing it at a first preset angle by the second locking member 32. The horizontal horizontality of the optical engine 5 is adjusted by rotating the third adjusting member 41 relative to the second adjusting member 21 around the X-axis and fixing it at a second preset angle by the third locking member 42. In this embodiment, the optical engine 5 can be adjusted in three degrees of freedom: vertical movement to adjust the distance between the optical engine 5 and the printing surface, rotation around the Y-axis to adjust the optical engine 5, and rotation around the X-axis to adjust the light projection direction (or angle) of the optical engine 5. The adjustment of the optical engine 5's rotation around the Y-axis and X-axis mainly regulates the horizontality of the optical engine 5 relative to the printing surface (i.e., the parallelism of the optical axis of the optical engine 5 relative to the Z-axis). This adjustment method is more convenient, efficient, and precise. Using a three-degree-of-freedom optical engine adjustment mechanism, the optical engine 5 can be quickly fine-tuned to its optimal position. The printer can then achieve precise printing by applying this mechanism. In other embodiments, the rotation center line of the second adjusting member 31 can be parallel to the X-axis, and the rotation center line of the third adjusting member 41 can be parallel to the Y-axis.
[0042] Furthermore, the first adjusting member 21 is provided with a first cylindrical shaft 211 extending along the Y-axis direction; the second adjusting member 31 is provided with a first hinge hole 311, the first cylindrical shaft 211 is hinged to the first hinge hole 311, the side wall of the first hinge hole 311 is provided with a first opening 3111, one of the two side walls opposite to the first opening 3111 is provided with a first through hole, and the other is provided with a first threaded hole, the second locking member 32 can pass through the first through hole and be threadedly connected to the first threaded hole, the second locking member 32 can not only be used to adjust rotation, but also has the purpose of facilitating hinge assembly. When the optical engine 5 needs to be rotated around the Y-axis for adjustment, the second locking member 32 is loosened, allowing the first hinge hole 311 of the second adjusting member 31 to rotate around the first cylindrical shaft 211 of the first adjusting member 21. When the second adjusting member 31 rotates to the first preset angle, the second locking member 32 is tightened, so that the first cylindrical shaft 211 and the first hinge hole 311 are interference-fitted, achieving relative fixation of the first adjusting member 21 and the second adjusting member 31, and realizing fine-tuning of the optical engine 5 around the Y-axis. It should be noted that the first hinge hole 311 can also be provided in the first adjusting member 21, and the first cylindrical shaft 211 can be provided in the second adjusting member 31.
[0043] Preferably, the optomechanical adjustment mechanism further includes a first limiting screw 6, a first adjusting member 21 having a first arc-shaped groove 212 with its center located on the axis of the first cylindrical shaft 211, and a second adjusting member 31 having a first limiting hole 312. The first limiting screw 6 passes through the first arc-shaped groove 212 and is threaded into the first limiting hole 312. When the optomechanical system 5 rotates around the Y-axis, the first limiting screw 6 slides within the first arc-shaped groove 212. The range of angles within which the second adjusting member 31 can rotate around the Y-axis is determined by the range of movement of the first limiting screw 6 within the first arc-shaped groove 212. The range of rotation of the optomechanical system 5 around the Y-axis is not very large, which meets the requirements for fine adjustment of the optomechanical system 5 around the Y-axis. It should be noted that the structure of the first limiting screw 6 and the fixing structure of the second locking member 32 can coexist, or only one of them can exist.
[0044] Furthermore, the third adjusting member 41 is provided with a second cylindrical shaft 411 extending along the X-axis; the second adjusting member 31 is provided with a second hinge hole 313, the second cylindrical shaft 411 is hinged to the second hinge hole 313, the side wall of the second hinge hole 313 is provided with a second opening 3131, one of the opposite side walls of the second opening 3131 is provided with a second through hole, and the other is provided with a second threaded hole, and the third locking member 42 can pass through the second through hole and be threadedly connected to the second threaded hole. When the optical engine 5 needs to be rotated around the X-axis for adjustment, the third locking member 42 is loosened to allow the second cylindrical shaft 411 of the third adjusting member 41 to rotate around the second hinge hole 313 of the second adjusting member 31. When the third adjusting member 41 rotates to the second preset angle, the third locking member 42 is tightened to allow the second cylindrical shaft 411 to be interference-fitted with the second hinge hole 313, thereby achieving relative fixation of the second adjusting member 31 and the third adjusting member 41 and realizing fine-tuning of the optical engine 5 around the X-axis.
[0045] In this embodiment, the second adjusting member 31 is U-shaped and includes a second base plate 314 and two second side plates 315 disposed opposite to each other on the second base plate 314. The two second side plates 315 are respectively provided with second hinge holes 313. The third adjusting member 41 has second cylindrical shafts 411 at both ends along the X-axis that are hinged to the second hinge holes 313. Both ends of the third adjusting member 41 are hinged to the second adjusting member 31, improving the connection stability between the third adjusting member 41 and the second adjusting member 31, and increasing the adjustment accuracy of the third adjusting member 41. It should be noted that alternatively, the second side plates 315 of the second adjusting member 31 may be provided with second cylindrical shafts 411, and the third adjusting member 41 may be provided with second hinge holes 313.
[0046] In this embodiment, the two second side plates 315 are vertically connected to both ends of the second base plate 314 by screws, so that the second adjusting member 31 has a U-shaped structure. The first hinge hole 311 is provided on the second base plate 314, and the second cylindrical shaft 411 is provided on the two second side plates 315. Of course, in other embodiments, the second adjusting member 31 can also be integrally formed.
[0047] Preferably, the optomechanical adjustment mechanism further includes a second limiting screw 7, and at least one of the two second side plates 315 is provided with a second arc-shaped groove 316, the center of which is located on the axis of the second cylindrical shaft 411. The third adjusting member 41 is provided with a second limiting hole 412, and the second limiting screw 7 passes through the second arc-shaped groove 316 and is threaded to the second limiting hole 412. When the optomechanical system 5 rotates around the X-axis for adjustment, the second limiting screw 7 slides within the second arc-shaped groove 316. The range of angles within which the third adjusting member 41 can rotate around the X-axis is determined by the range of movement of the second limiting screw 7 within the second arc-shaped groove 316. The range of rotation of the optomechanical system 5 around the X-axis is not very large, which can meet the needs of fine adjustment of the optomechanical system 5 around the X-axis. It should be noted that the structure of the second limiting screw 7 and the fixing structure of the third locking member 42 can coexist, or only one of them can exist.
[0048] In this embodiment, the third adjusting member 41 is U-shaped and includes a third base plate and two third side plates disposed opposite to each other on the third base plate. A second cylindrical shaft 411 is disposed on the opposite side of the two third side plates.
[0049] In this embodiment, as Figures 2-4 As shown, the optical engine 5 is connected to the third adjusting member 41 by screws. In other embodiments, the third adjusting member 41 and the optical engine 5 can also be integrally formed. Alternatively, the third adjusting member 41 can omit the third base plate.
[0050] Furthermore, the main body of the optical device is provided with a fixing plate 1, and the fixing plate 1 is provided with a sliding groove 11 extending along the Z-axis direction. The first adjusting member 21 is slidably connected in the sliding groove 11 to improve the movement accuracy of the first adjusting member 21 along the Z-axis direction. The main body of the optical device and the fixing plate 1 can be integrally formed.
[0051] In this embodiment, the connecting portions of the first adjusting member 21, the second adjusting member 31, and the third adjusting member 41 are all plate-shaped. The first adjusting member 21, the second adjusting member 31, the third adjusting member 41, and the optical engine 5 are stacked. This optical engine adjustment mechanism has a compact structure and occupies little space. In this embodiment, the connecting portions of the first adjusting member 21, the second adjusting member 31, and the third adjusting member 41, and the optical engine 5 are stacked along the Y-axis direction, and the connecting portions of the second adjusting member 31 and the third adjusting member 41, and the optical engine 5 are stacked along the X-axis direction. Specifically, the first adjusting member 21, the second base plate 314, the third base plate, and the optical engine 5 are stacked along the Y-axis, and the second side plate 315, the third side plate, and the optical engine 5 are stacked along the X-axis.
[0052] In this embodiment, the bottom of the slide groove 11 is provided with an oblong hole 12 extending along the Z-axis direction, and the first adjusting member 21 is provided with a third threaded hole 213; the first locking member 22 can pass through the oblong hole 12 and be threadedly connected to the third threaded hole 213. When it is necessary to adjust the height of the optical engine 5, the first locking member 22 is loosened, and the first adjusting member 21 is moved up and down along the Z-axis direction. When the first adjusting member 21 moves to the preset height, the first locking member 22 is tightened, thereby achieving relative fixation between the first adjusting member 21 and the fixed plate 1, and realizing the height adjustment of the optical engine 5 along the Z-axis direction. Furthermore, the first locking member 22 slides within the oblong hole 12, and the oblong hole 12 provides a travel limit for the fixed plate 1 along the Z-axis direction.
[0053] Preferably, the first adjusting member 21 is provided with at least two third threaded holes 213, and the first locking member 22 corresponds one-to-one with the third threaded holes 213. The at least two third threaded holes 213 are spaced apart along the Z-axis. In this embodiment, there are two third threaded holes 213 and two first locking members 22. The first adjusting member 21 is connected to the fixed plate 1 through the two first locking members 22, which improves the connection stability between the first adjusting member 21 and the fixed plate 1.
[0054] Compared to other existing technologies, this optical engine adjustment mechanism is simpler. Firstly, it occupies less space and requires less material, reducing manufacturing costs. Secondly, it offers higher precision in adjusting the optical engine 5. While its adjustable range is relatively small, users only need to make minor adjustments to the three degrees of freedom to quickly fine-tune the optical engine 5 to its optimal position, achieving accurate printing. Thirdly, this optical engine adjustment mechanism is innovative in adjusting the horizontality of the optical engine 5. Most existing technologies use a single plane and screws at the four corners to control the horizontality of the optical engine 5. In contrast, this embodiment controls the horizontality of the optical engine 5 by rotating it around the Y-axis and the X-axis, making the adjustment method more convenient, efficient, and precise.
[0055] This embodiment also provides a printer, including a body and an optical engine 5, the optical engine 5 being mounted on the body via the aforementioned optical engine adjustment mechanism. The printer also includes a printing platform. In one embodiment, the printing platform is located above the optical engine 5, and the optical engine 5 is adjusted by the optical engine adjustment mechanism so that the optical axis of the optical engine 5 is perpendicular to the printing plane and the distance between the optical engine 5 and the printing plane is at a preset distance, with the printing plane parallel to the forming surface (i.e., the bottom surface) of the printing platform.
