[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] The following is combined Figures 1 to 4 This invention describes a modular optomechanical assembly, comprising:

[0032] Mounting component 1, which includes a mounting bracket 11 and a fixing seat 12. The fixing seat 12 is connected to one end of the mounting bracket 11 and has a light-transmitting part for mounting the material box.

[0033] Optical engine module 2 is connected to the mounting bracket 11 and is positioned directly opposite the light-transmitting part. Along the projection direction of the optical engine module 2, the mounting base 12 is located in front of the optical engine module 2.

[0034] Please refer to Figure 1 and Figure 4 A mounting bracket 11 is connected to a fixed base 12 above it. Because the material box contains raw materials, the overall weight of the box is relatively large. The fixed base 12 needs to support the material box, so it is preferably a rectangular flat plate. By increasing the contact area between the fixed base 12 and the material box, the pressure on the fixed base 12 is reduced. Simultaneously, since the raw materials stored in the material box are mostly liquid, the area of ​​the fixed base 12 can be set to be larger than the bottom area of ​​the material box, making the material box more stable when placed on the fixed base 12. In this embodiment, the fixed base 12 is connected to the mounting bracket 11 through its four corners and supports the material box through its central portion.

[0035] On the side of the mounting bracket 11 opposite to the fixing base 12, i.e., below the mounting bracket 11, a connecting plate 18 is also installed, through which the optical engine module 2 is mounted. Because the optical engine module 2 needs to irradiate the raw materials in the material box to operate, the lens of the optical engine module 2 is positioned facing the fixing base 12, so that the lens of the optical engine module 2 is directly facing the fixing base 12. Along the projection direction of the optical engine module 2, the fixing base 12 is located in front of the optical engine module 2, i.e., the optical engine module 2 is irradiating the fixing base 12. Preferably, the lens of the optical engine module 2 is directly facing the center of the fixing base 12. Because the optical engine module 2 needs to emit light towards the fixing base 12, the mounting bracket 11 is hollow and will not obstruct the optical engine module 2. At the same time, a light-transmitting part is provided on the fixing base 12, and the material box is placed on the light-transmitting part. The light-transmitting part can also project light, thereby preventing the fixing base 12 from obstructing the optical engine module 2.

[0036] Since both the fixed base 12 and the connecting plate 18 are mounted on the mounting bracket 11, the fixed base 12 is used to install the material box and the connecting plate 18 is used to install the optical engine module 2. Therefore, the material box and the optical engine module 2 are installed together by the mounting bracket 11, so that the mounting bracket 11, the material box and the optical engine module 2 form a whole, making the whole device modular.

[0037] In this embodiment, the material box and the optical engine module 2 are installed together by the mounting bracket 11, which makes it easier to put the material box and the optical engine module 2 into place as a whole, thus improving the maintenance efficiency of the material box and the optical engine module 2.

[0038] In one embodiment, along the projection direction of the optical engine module 2, the mounting bracket 11 is provided with multiple mounting positions, and the optical engine module 2 is mounted in different mounting positions through the connecting plate 18 to adjust the distance between the optical engine module 2 and the fixed base 12.

[0039] like Figure 1 As shown, the fixing base 12 and the connecting plate 18 are arranged at intervals along the length of the mounting bracket 11. Multiple mounting positions are provided along the length of the mounting bracket 11. Because the connecting plate 18 needs to be disassembled after being installed on the mounting bracket 11 for repair or replacement, the connection between the connecting plate 18 and the mounting bracket 11 is detachable. Preferably, the connection between the connecting plate 18 and the mounting bracket 11 is a threaded connection. Therefore, the multiple mounting positions on the mounting bracket 11 are equivalent to multiple sets of mounting holes provided along the length of the mounting bracket 11.

[0040] Because the optical engine module 2 operates by emitting light to the bottom of the material box, it needs to focus at the bottom of the box. Therefore, the distance between the optical engine module 2 and the bottom of the box is the focal length. The bottom of the box is placed on the mounting base 12, and the optical engine module 2 is mounted on the connecting plate 18. Therefore, the distance between the mounting base 12 and the connecting plate 18 is also the focal length. The mounting base 12 remains in its fixed position on the mounting bracket 11, while the connecting plate 18 can be adjusted through multiple mounting positions on the mounting bracket 11, thereby changing the distance between the mounting base 12 and the connecting plate 18.

[0041] Because different specifications of the optical engine module 2 have different focal lengths, the optical engine module 2 needs to be installed at different distances from the mounting base 12. In this embodiment, the optical engine module 2 is installed on the connecting plate 18. By installing the connecting plate 18 in different mounting positions, the distance between the mounting base 12 and the connecting plate 18 can be adjusted to accommodate optical engine modules 2 with different focal lengths.

[0042] In one embodiment, the fixed base 12 has a liquid storage tank 121, and the material box is installed in the liquid storage tank 121.

[0043] The liquid storage tank 121 is located in the middle of the fixed base 12, ensuring that the material box is centered on the fixed base 12 during installation, resulting in more balanced force and more stable installation. Furthermore, since the material box is installed inside the liquid storage tank 121, any leakage will cause the liquid to fall into the liquid storage tank 121, collecting within it for easy subsequent cleaning.

[0044] Please refer to the above as well. Figure 2 and Figure 3 In this embodiment, the material box is installed through the adapter 17, so the liquid storage tank 121 is opened on the adapter 17.

[0045] In this embodiment, by designing a liquid storage tank 121 on the fixed base 12 to collect the leakage of the material box, the cleaning efficiency can be improved.

[0046] In one embodiment, the mounting assembly 1 further includes a heating element 14 connected to the mounting base 12 for heating the material box mounted on the mounting base 12. In one embodiment, the heating element 14 is arranged around the outer ring of the glass 13.

[0047] The mounting base 12 is also equipped with a heating element 14, which is annular. Because the heating element 14 blocks light, it needs to be arranged around the outer ring of the light-transmitting part. After the material box is placed on the light-transmitting part, the outer ring of the bottom of the material box is aligned with the heating element 14, and then the bottom of the material box is heated by the heating element 14.

[0048] In this embodiment, the heating element 14 heats the material box, thereby transferring heat to the raw material inside the material box to prevent the raw material from being too cold to print properly in cold weather.

[0049] In one embodiment, the mounting assembly 1 further includes an adapter 17 and a light-transmitting plate 13 connected to the adapter 17. The adapter 17 is detachably connected to the fixing base 12. The light-transmitting plate 13 is arranged facing the light-transmitting part, and the material box is disposed on the light-transmitting plate 13.

[0050] Please refer to the above as well. Figure 2 and Figure 3 An adapter 17 is provided on the fixed base 12, and a light-transmitting plate 13 is mounted on the adapter 17. Preferably, the light-transmitting plate 13 is made of glass. After the adapter 17 is installed on the fixed base 12, the light-transmitting plate 13 is aligned with the light-transmitting part of the fixed base 12, so that the light emitted by the optical engine module 2 can smoothly illuminate the bottom of the material box.

[0051] Because the light transmission effect of the light-transmitting plate 13 has a significant impact on the optical engine module 2, it is necessary to ensure that the light transmission effect of the light-transmitting plate 13 is within the usable range. When the light-transmitting plate 13 is worn, its light transmission effect decreases, and it can no longer be used, so it needs to be replaced in time. In this embodiment, the light-transmitting plate 13 is mounted on the adapter 17, and the adapter 17 and the light-transmitting plate 13 are a single module. The adapter 17 is detachably connected to the mounting base 12, so the adapter 17 can be removed from the mounting base 12, and then the adapter 17 with the unworn light-transmitting plate 13 can be reinstalled on the mounting base 12.

[0052] In this embodiment, the light-transmitting plate 13 can be quickly replaced by the adapter 17 and the fixed base 12, ensuring that the operation of the optical engine module 2 is not affected.

[0053] In one embodiment, the mounting assembly 1 further includes a first circuit board 15 and a second circuit board 16. The first circuit board 15 and the heating element 14 are both connected to the adapter 17. The first circuit board 15 is connected to the heating element 14 to conduct electricity between the heating element 14 and the second circuit board 16. The second circuit board 16 is connected to the mounting base 12. The second circuit board 16 and the first circuit board 15 are connected by a contact switch. The second circuit board 16 is used to connect the first circuit board 15 to the device motherboard.

[0054] like Figure 3 As shown, the first circuit board 15 is directly connected to the heating element 14 and is used to control the heating element 14 to heat or stop heating. The second circuit board 16 is the overall controller, capable of receiving signals from various components of the machine. The second circuit board 16 is connected to the contact switch of the first circuit board 15. The second circuit board 16 determines whether heating is needed based on the overall machine signals and then transmits the signal to the first circuit board 15, which then controls the heating element 14. Furthermore, because the material box is located above the first circuit board 15 and the second circuit board 16, there is a risk of leakage. Therefore, the first circuit board 15 and the second circuit board 16 need to have good sealing performance to prevent the first circuit board 15 or the second circuit board 16 from burning out.

[0055] In this embodiment, the adapter 17 is mounted on the fixed base 12, and the material box is mounted on the adapter 17, meaning the material box is installed on the fixed base 12 via the adapter 17. Therefore, the heating element 14 is connected to the adapter 17, bringing it closer to the material box, and the heating element 14 is positioned between the adapter 17 and the fixed base 12. Furthermore, the material box and the adapter 17 are in direct contact, and the heating element 14 is also in direct contact with the adapter 17. The heating element 14 directly transfers heat to the material box through the solid-state adapter 17, improving the heating efficiency of the heating element 14.

[0056] Because the adapter 17 is detachably connected to the mounting base 12, and the heating element 14 is connected to the adapter 17, the heating element 14 can be installed and removed together with the adapter 17. However, the second circuit board 16 is the overall controller and is fixedly installed inside the machine; it cannot be removed with the adapter 17. Therefore, in this embodiment, the first circuit board 15 is connected to the adapter 17, and the heating element 14 is connected via the first circuit board 15. Then, the first circuit board 15 and the second circuit board 16 are connected via contacts, allowing both the heating element 14 and the first circuit board 15 to be installed and removed together with the adapter 17, without affecting the circuit connection between the heating element 14 and the second circuit board 16. After the adapter 17 is installed on the mounting base 12, the heating element 14 is positioned between the adapter 17 and the mounting base 12, and the first circuit board 15 and the second circuit board 16 are electrically connected, thus enabling control of the heating element 14 for heating.

[0057] In one embodiment, the modular optical engine assembly further includes a dust cover 4, which is connected between the light-transmitting plate 13 and the optical engine module 2, and is mutually sealed with the light-transmitting plate 13 and the optical engine module 2. In one embodiment, the width of the dust cover 4 gradually increases along the direction from the optical engine module 2 toward the light-transmitting plate 13. In one embodiment, the modular optical engine assembly further includes foam 5, which is disposed on the side of the optical engine module 2 facing the mounting base 12, and is used to seal the lens of the optical engine module 2.

[0058] like Figure 1 As shown, the dust cover 4 is connected to the light-transmitting plate 13 and the optical engine module 2 at both ends, respectively, and the connection method is a sealed connection. Preferably, the dust cover 4 and the light-transmitting plate 13, as well as the dust cover 4 and the optical engine module 2, are sealed with sealing rings. Because the lens of the optical engine module 2 needs to emit light to work, in order to avoid the influence of dust and other impurities in the environment on the lens of the optical engine module 2, a dust cover 4 is provided in the optical path directly from the optical engine module 2 to the light-transmitting plate 13. The dust cover 4 seals the optical path to prevent dust and other impurities in the environment from entering the optical path.

[0059] Meanwhile, the width of the dust cover 4 on the side closer to the optical engine module 2 is smaller than the width of the dust cover 4 on the side closer to the light-transmitting plate 13. Because the lens area in the optical engine module 2 is small, the dust cover 4 only needs to cover the lens in the optical engine module 2, so the width of the dust cover 4 on this side is smaller. Light emitted from the lens in the optical engine module 2 toward the light-transmitting plate 13 has a wider angle of view the further away from the lens, so the width of the dust cover 4 is also larger, so that it can completely illuminate the light-transmitting plate 13.

[0060] In one embodiment, the dust cover 4 includes connecting portions at both ends and telescopic portions between the connecting portions, the telescopic portions being used to adjust the length of the dust cover 4.

[0061] like Figure 1 As shown, in this embodiment, the dust cover 4 is retractable. Because the optical engine module 2 has different focal lengths, the distance between the connecting plate 18 and the fixing base 12 needs to be adjusted. Similarly, the dust cover 4, which connects the optical engine module 2 to the light-transmitting plate 13, also needs to have its length adjusted accordingly. In this embodiment, the dust cover 4 is retractable to accommodate adjustments of different spacings.

[0062] like Figure 4 As shown, foam 5 is also provided on the optical engine module 2, covering the lens of the optical engine module 2 to seal and protect the lens. The double protection provided by foam 5 and dust cover 4 extends the service life of the optical engine module 2. Furthermore, when the dust cover 4 is disassembled for maintenance, the foam 5 also protects the optical engine module 2.

[0063] This utility model also provides a 3D printer, including a frame, a material box, and a modular optomechanical assembly as described above. The frame is provided with a mounting cavity and a mounting port communicating with the mounting cavity. The modular optomechanical assembly is disposed in the mounting cavity along the mounting port, and the material box is disposed on the modular optomechanical assembly and covers the mounting port.

[0064] In the existing technology, the material box is usually taken out from the first exit of the rack and the optical engine module 2 is taken out from the second exit of the rack. Separating the material box and the optical engine module 2 for removal takes more time and reduces work efficiency.

[0065] In this embodiment, the modular optomechanical assembly is first placed in the mounting cavity along the mounting port and connected to the frame inside the mounting cavity via the fixing base 12. Then, the material box is placed on the fixing base 12, and the mounting port is sealed. The modular optomechanical assembly mounts the material box and the optomechanical module 2 together, allowing both to be removed from the mounting port simultaneously, thus improving work efficiency.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
