Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically a three-wave collaborative printing light source device. Background Technology

[0002] A DLP (Digital Light Processing) printer is a high-precision 3D printing device based on Digital Light Processing (DLP) technology and photopolymerization principle. It uses digital light projection to solidify liquid photosensitive resin layer by layer to build a three-dimensional solid model.

[0003] Existing printing light source equipment often places the device directly on the ground during use. Vibrations can easily affect beam alignment, and the equipment is often semi-open, making it susceptible to irritating gases generated during printing that can affect personnel. Therefore, this invention provides a three-wave synergistic printing light source device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a three-wave collaborative printing light source device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A three-wave collaborative printing light source device includes a housing, a buffer platform, and actuators. The buffer platform is attached to the lower end of the housing via a second mounting component. A piezoelectric sensor is installed on the buffer platform, and several actuators are installed at the lower end of the buffer platform. The actuators are mounted on bases at the lower ends. A support plate is installed inside the housing, with a light source device at the lower end of the support plate. A material trough device is installed at the upper end of the support plate, and a frame is installed at the upper end of the support plate. A forming platform device is installed on the frame via a drive device. An operation screen is installed on the housing, and the housing has a transparent door. Air inlet pipes are installed at both ends of the housing, with one-way valves and dustproof components on the air inlet pipes. An exhaust pipe is installed at the upper end of the housing, with an exhaust fan inside the exhaust pipe. A filter element is installed on the upper side of the exhaust fan, and a cover plate is installed on the upper end of the filter element. An exhaust port is provided on the cover plate corresponding to the filter element, and a first mounting component is installed on the housing corresponding to the cover plate.

[0006] Specifically, the wavelength range of the light source is broadened in the light source device, and a dual-wavelength light source array is adopted: a 405nm chip and a 385nm chip. The 385nm chip has higher wavelength energy and can excite more types of cationic photoinitiators and some free radical photoinitiators, effectively improving the curing speed and curing depth of the bottom layer. The 405nm chip is the mainstream wavelength for most resins, ensuring compatibility. The two work together to significantly improve the curing efficiency of mixed resins. Based on the dual-wavelength light source array, a 415nm chip is added. The 415nm chip wavelength has deeper penetration and better matching with certain special resins (such as some biocompatible resins and high-toughness resins). At the same time, the longer wavelength can reduce light scattering and help improve the printing accuracy in the vertical direction. The three wavelengths cover the key bands from ultraviolet to violet light, achieving "full band" efficient curing. When using this device, the chamber is placed on a buffer platform. The second mounting component facilitates the limiting and fixing of the chamber. A piezoelectric sensor monitors vibration, and an actuator generates a counterforce to actively counteract vibrations from the ground and the inside of the equipment, ensuring long-term stable beam alignment. The combination of the chamber and transparent door structure allows for a closed state during printing, preventing the diffusion of irritating gases generated during printing. Simultaneously, an exhaust fan extracts the irritating gases from the chamber, which are then filtered and discharged, preventing workers from being affected by the irritating gases. When the filter needs to be replaced, the first mounting component allows for easy removal of the cover plate, facilitating filter replacement. The dustproof component prevents large dust and impurities from entering the chamber.

[0007] As a further embodiment of this utility model, the second installation component includes a fixing block and a locking block. The fixing blocks are provided at the left and right ends of the housing, and the locking blocks are engaged at the front and rear ends of the fixing blocks. The locking blocks are provided with second locking grooves at the front and rear ends of the fixing blocks corresponding to the locking blocks. The locking blocks are threadedly connected to threaded rods, and the threaded rods are provided with two opposite thread lines corresponding to the two locking blocks. The threaded rods are symmetrically provided with bearing seats at the front and rear, and the lower ends of the bearing seats are fixedly connected to the buffer platform. By rotating the threaded rods, the threaded rods drive the two locking blocks to move closer to each other, and the locking blocks are inserted into the second locking grooves on the fixing blocks, thereby limiting and fixing the housing.

[0008] As a further embodiment of this utility model, the threaded rod is provided with a handle at its front end, and the two locking blocks are provided with a telescopic rod at one end away from each other. The other end of the telescopic rod is provided with a mounting plate, and the lower end of the mounting plate is fixedly connected to the buffer platform. The handle facilitates the rotation of the threaded rod, and the telescopic rod facilitates the rotation of the locking blocks, preventing the locking blocks from rotating on their own as the threaded rod rotates.

[0009] As a further embodiment of this utility model, the dustproof component includes a dustproof cover, the air inlet pipe is provided with a dustproof cover, the dustproof cover is provided with a filter frame, and the filter frame is provided with a filter screen. The filter frame and the filter screen prevent large dust and impurities from entering the box.

[0010] As a further embodiment of this utility model, the filter screen frame is provided with a bearing, the inner ring of the bearing is provided with a rotating shaft, the rotating shaft is provided with a cleaning brush plate that fits against the filter screen frame, and a first motor is provided at one end of the two rotating shafts that are close to each other. The first motor is fixedly connected to the inner wall of the dust cover through a connecting frame. By starting the first motor, the rotating shaft and the cleaning brush plate are driven to rotate, and the cleaning brush plate cleans the filter screen.

[0011] As a further embodiment of this utility model, the first mounting component includes a vertical plate and a locking rod. The lower end of the cover plate is symmetrically provided with vertical plates, and the front and rear ends of the vertical plates are engaged with locking rods. The front and rear ends of the vertical plates are provided with first locking grooves corresponding to the locking rods. By engaging the locking rods with the first locking grooves, the locking rods can conveniently limit and fix the vertical plates, thereby facilitating the limiting and fixing of the cover plate.

[0012] As a further embodiment of this utility model, the lever is provided with a connecting plate, and a fixed plate is slidably connected to the lever. The lower end of the fixed plate is fixedly connected to the housing. A pull plate is provided at the end of the lever away from the vertical plate. A spring is sleeved on the lever. One end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the fixed plate. The elastic potential energy of the spring facilitates the lever to return to its original position. When the filter element needs to be replaced, the two pull plates are pulled to move the lever away from each other, and the lever separates from the first slot, thereby facilitating the removal of the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this utility model, the box is placed on a buffer platform. The second mounting component facilitates the limiting and fixing of the box. The piezoelectric sensor monitors the vibration, and the actuator generates a reverse force to actively counteract the vibration from the ground and the inside of the equipment, which helps to ensure the long-term stable alignment of the beam.

[0014] 2. When this utility model is in use, the combination of the box and transparent door structure facilitates a closed state during printing, preventing the diffusion of irritating gases generated during printing. At the same time, the exhaust fan is activated to extract the irritating gases from the box, which are then filtered and adsorbed by the filter element before being discharged, preventing the staff from being affected by the irritating gases. When the filter element needs to be replaced, the cover plate can be easily removed through the first installation component, making it convenient to replace the filter element. The dustproof component helps to prevent large dust and impurities from entering the box. Attached Figure Description

Therefore, this invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.

[0023] Example Please see Figures 1-5 In this embodiment of the present invention, a three-wave collaborative printing light source device includes a housing 1, a buffer platform 2, and actuators 3. The lower end of the housing 1 is attached to the buffer platform 2 via a second mounting assembly 15. A piezoelectric sensor is provided on the buffer platform 2, and several actuators 3 are provided at the lower end of the buffer platform 2. A base 4 is provided at the lower end of each actuator 3. A support plate 10 is provided inside the housing 1. A light source device 7 is provided at the lower end of the support plate 10, and a material trough device 5 is provided at the upper end of the support plate 10. A frame 8 is provided at the upper end of the support plate 10, and a forming platform device 6 is provided on the frame 8 via a driving device 9. The box body 1 is equipped with an operation screen 101 and a transparent door 102. The left and right ends of the box body 1 are equipped with air inlet pipes 11, and the air inlet pipes 11 are equipped with one-way valves 1101 and dustproof components 12. The upper end of the box body 1 is equipped with an exhaust pipe 13, and an exhaust fan 1301 is installed inside the exhaust pipe 13. The upper side of the exhaust fan 1301 is equipped with a filter element 1303, and the upper end of the filter element 1303 is equipped with a cover plate 1302. The cover plate 1302 is equipped with an exhaust port 1304 corresponding to the filter element 1303, and the box body 1 is equipped with a first mounting component 14 corresponding to the cover plate 1302.

[0024] Specifically, the light source device in this equipment expands the wavelength range of the light source by adopting a dual-wavelength light source array: a 405nm chip and a 385nm chip. The 385nm chip has higher wavelength energy and can excite more types of cationic photoinitiators and some free radical photoinitiators, effectively improving the curing speed and curing depth of the substrate. The 405nm chip is the mainstream wavelength for most resins, ensuring compatibility. The two work together to significantly improve the curing efficiency of mixed resins. Based on the dual-wavelength light source array, a 415nm chip is added. The 415nm chip wavelength has deeper penetration and better matching with certain special resins (such as some biocompatible resins and high-toughness resins). At the same time, the longer wavelength can reduce light scattering and help improve the printing accuracy in the vertical direction. The three wavelengths cover the key bands from ultraviolet to violet light, achieving "full band" efficient curing. Furthermore, the housing 1 is placed on the buffer platform 2. The second mounting component 15 is used to limit and fix the housing 1. Vibration is monitored by a piezoelectric sensor, and the actuator 3 generates a counterforce to actively counteract vibrations from the ground and the inside of the equipment, ensuring long-term stable beam alignment. The combination of the housing 1 and the transparent door 102 structure allows the printing process to be closed, preventing the diffusion of irritating gases generated during printing. At the same time, the exhaust fan 1301 is activated to extract the irritating gases from the housing 1, which are then filtered and adsorbed by the filter element 1303 before being discharged, preventing the staff from being affected by the irritating gases. When the filter element 1303 needs to be replaced, the cover plate 1302 can be removed by the first mounting component 14, making it convenient to replace the filter element 1303. The dustproof component 12 helps to prevent large dust and impurities from entering the housing 1.

[0025] The second installation component 15 includes a fixing block 1501 and a locking block 1503. The fixing blocks 1501 are provided at the left and right ends of the housing 1. The locking blocks 1501 are engaged with the locking blocks 1503 at the front and rear ends. The fixing blocks 1501 are provided with second locking grooves 1502 corresponding to the locking blocks 1503 at the front and rear ends. The locking blocks 1503 are threadedly connected to threaded rods 1504. The threaded rods 1504 are provided with two opposite thread lines corresponding to the two locking blocks 1503. The threaded rods 1504 are symmetrically provided with bearing seats 1505 at the front and rear. The lower end of the bearing seats 1505 is fixedly connected to the buffer platform 2.

[0026] Specifically, the threaded rod 1504 is rotated, which in turn drives the two locking blocks 1503 to move closer to each other. The locking blocks 1503 are then inserted into the second locking groove 1502 on the fixing block 1501, thereby limiting and fixing the box 1.

[0027] The threaded rod 1504 has a handle 1506 at its front end, and the two locking blocks 1503 have a telescopic rod 1507 at one end that is far apart from each other. The other end of the telescopic rod 1507 has a mounting plate 1508, and the lower end of the mounting plate 1508 is fixedly connected to the buffer platform 2.

[0028] Specifically, the handle 1506 facilitates the rotation of the threaded rod 1504, and the telescopic rod 1507 facilitates the rotation of the locking block 1503, preventing the locking block 1503 from rotating on its own as the threaded rod 1504 rotates.

[0029] The dustproof component 12 includes a dust cover 1201, the air inlet pipe 11 is provided with a dust cover 1201, the dust cover 1201 is provided with a filter frame 1202, and the filter frame 1202 is provided with a filter.

[0030] Specifically, the filter frame 1202 and the filter screen prevent large dust and impurities from entering the housing 1.

[0031] The filter frame 1202 is provided with a bearing 1205, and the inner ring of the bearing 1205 is provided with a rotating shaft 1204. The rotating shaft 1204 is provided with a cleaning brush plate 1206 that fits against the filter frame 1202. The two rotating shafts 1204 are provided with a first motor 1203 at one end close to each other. The first motor 1203 is fixedly connected to the inner wall of the dust cover 1201 through a connecting frame.

[0032] Specifically, by starting the first motor 1203, the rotating shaft 1204 and the cleaning brush 1206 are driven to rotate, and the cleaning brush 1206 cleans the filter screen. No manual cleaning is required, saving time and effort.

[0033] The first mounting component 14 includes a vertical plate 1401 and a locking rod 1403. The lower end of the cover plate 1302 is symmetrically provided with the vertical plate 1401. The front and rear ends of the vertical plate 1401 are engaged with the locking rod 1403. The front and rear ends of the vertical plate 1401 are provided with a first locking groove 1402 corresponding to the locking rod 1403.

[0034] Specifically, by engaging the locking rod 1403 with the first locking slot 1402, the locking rod 1403 facilitates the limiting and fixing of the vertical plate 1401, thereby facilitating the limiting and fixing of the cover plate 1302.

[0035] The lever 1403 is provided with a connecting plate 1404, and a fixing plate 1405 is slidably connected to the lever 1403. The lower end of the fixing plate 1405 is fixedly connected to the housing 1. A pull plate 1407 is provided at the end of the lever 1403 away from the vertical plate 1401. A spring 1406 is sleeved on the lever 1403. One end of the spring 1406 is fixedly connected to the connecting plate 1404, and the other end of the spring 1406 is fixedly connected to the fixing plate 1405.

[0036] Specifically, the elastic potential energy of the spring 1406 facilitates the return of the locking rod 1403 to its original position. When the filter element 1303 needs to be replaced, the two pull plates 1407 are pulled to move the locking rod 1403 away from each other, and the locking rod 1403 separates from the first locking groove 1402, thereby facilitating the disassembly of the cover plate 1302 and making it convenient to replace the filter element 1303.

[0037] The working principle of this utility model is as follows: In use, the housing 1 is placed on the buffer platform 2. Rotating the handle 1506 drives the threaded rod 1504 to rotate, which in turn drives the two locking blocks 1503 to move closer together. The locking blocks 1503 then insert into the second slot 1502 on the fixing block 1501, thereby limiting and fixing the housing 1. Vibration is monitored by a piezoelectric sensor, and the actuator 3 generates a counterforce to actively counteract vibrations from the ground and the inside of the equipment, ensuring long-term stable beam alignment. The combination of the housing 1 and the transparent door 102 structure allows the printing process to be kept in a closed state, preventing the diffusion of irritating gases generated during printing. At the same time, the exhaust fan 1301 is activated to ventilate the housing. Irritating gases are extracted from the chamber 1 and discharged after being filtered and adsorbed by the filter element 1303, preventing workers from being affected by irritating gases. When the filter element 1303 needs to be replaced, pulling the two pull plates 1407 causes the locking rod 1403 to move away from each other, and the locking rod 1403 separates from the first locking groove 1402, thus facilitating the removal of the cover plate 1302 and the replacement of the filter element 1303. The filter screen frame 1202 and the filter screen prevent large dust and impurities from entering the chamber 1. At the same time, the first motor 1203 is started to drive the rotating shaft 1204 and the cleaning brush plate 1206 to rotate, and the cleaning brush plate 1206 cleans the filter screen. No manual cleaning is required, saving time and effort.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
