Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and in particular to an automated post-processing device for the surface of 3D printed parts. Background Technology

[0002] With its flexible forming capabilities, 3D printing technology has been widely used in aerospace, automotive manufacturing, medical equipment, consumer electronics and other fields. This technology can quickly transform design models into physical parts, greatly shortening product development cycles and reducing customized production costs. However, during the 3D printing process, due to the characteristics of printing materials, forming process principles such as fused deposition modeling, photopolymerization, selective laser sintering and so on, as well as the limitations of equipment precision, various defects are easily generated on the surface of printed parts. At this time, automated post-processing equipment for the surface of 3D printed parts is required to process them.

[0003] Currently, after 3D printed parts are finished, their surfaces often have incompletely cured powder particles, resin residue, or molten material residue, affecting the smoothness and aesthetics of the parts. After printing some complex structures, support material may remain in internal gaps or dead corners. These surface defects directly affect the subsequent use of 3D printed parts. Furthermore, current post-processing methods for 3D printed parts have limitations. Traditional manual cleaning is not only inefficient and labor-intensive, but also prone to causing dimensional deviations or surface scratches due to improper operation. In addition, existing equipment structures are relatively fixed, making it difficult to clean the equipment after cleaning the 3D printed parts, resulting in residue accumulation inside the equipment, which is detrimental to maintaining the effectiveness of the equipment in cleaning 3D printed parts. Summary of the Invention

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] Reference Figure 1-16 An embodiment of the present invention provides an automated post-processing device for the surface of 3D printed parts, including a loading mechanism 1, a cleaning mechanism 2 disposed in the middle of the loading mechanism 1, a connecting vibration mechanism 3 fixedly connected to the upper left side of the loading mechanism 1, and a lever control mechanism 4 fixedly connected to the upper right side of the loading mechanism 1.

The ends of the multiple connecting plates 29 away from the positioning blocks 15 are all fixedly connected to the upper rear side of the main frame plate 21. A filter cylinder groove 23 is fixedly connected to the lower side of the main frame plate 21. A fixing ring 24 is fixedly connected to the inner wall of the middle part of the filter cylinder groove 23. A rotating cylinder 25 is rotatably connected to the end of the fixing ring 24 near the opening side of the filter cylinder groove 23. A cleaning component 26 is set in the middle of the rotating cylinder 25.

[0012] A linkage component 27 is provided in the middle of the unopened side of the filter cylinder trough 23. A splash guard 28 is fixedly connected to the upper side of the main frame plate 21. Multiple ultrasonic transducers 210 are fixedly connected to the inner front wall of the filter cylinder trough 23. Cleaning fluid is injected into the filter cylinder trough 23. The splash guard 28 can prevent liquid from splashing during the cleaning process. The ultrasonic transducer 210 is activated. The ultrasonic vibration acts on the cleaning fluid to generate high-frequency pressure waves, which peel off impurities such as powder particles and resin residues from the surface of the printed parts, and at the same time clean the gaps and dead corners inside the complex structure.

[0013] The cleaning assembly 26 includes a filter washing cylinder 262 disposed in the middle of the rotating drum 25, a mounting ring 261 fixedly connected to the outer wall of the end of the filter washing cylinder 262 near the opening of the filter cylinder groove 23, and two mounting components 263 respectively fixedly connected to the middle of the two sides of the mounting ring 261. A cylinder cover 264 is hinged to the side of the mounting ring 261 away from the rotating drum 25, and a connecting groove 265 is provided on the side of the filter washing cylinder 262 away from the mounting ring 261.

[0014] The two mounting components 263 include two hollow tubes 2631 respectively fixedly connected to the middle of opposite sides of the mounting ring 261, a disassembly rod 2632 slidably connected inside the hollow tubes 2631, and an inner cavity 2633 formed at the end of the disassembly rod 2632 away from the mounting ring 261. A locking block 2634 is rotatably connected to the inner wall of the inner cavity 2633 away from the mounting ring 261. The middle part of the locking block 2634 is connected to the inner wall of the inner cavity 2633 via a torsion spring 2635. A spring 2636 is fixedly connected to the inner wall of the end of the hollow tube 2631 away from the mounting ring 261. A stabilizing block 2637 is fixedly connected to the end of the spring 2636 near the disassembly rod 2632. The stabilizing block 2637 is slidably connected inside the hollow tube 2631 to stabilize the tube. The side of block 2637 away from spring 2636 is fixedly connected to the side of disassembly rod 2632 near spring 2636. When using this device, open the cylinder cover 264 of cleaning assembly 26, put the 3D printed part to be processed into the filter washing cylinder 262, close the cylinder cover 264 to complete the seal, and fix the filter washing cylinder 262 to the rotating cylinder 25 through the mounting component 263. Align the hollow tube 2631 with the insertion hole 2638 of the rotating cylinder 25 and insert it. The locking block 2634 at the end of disassembly rod 2632 pops out under the action of torsion spring 2635 and locks into the locking groove 2639 on the inner wall of insertion hole 2638. At the same time, spring 2636 presses the disassembly rod 2632 through stabilizing block 2637 to ensure that filter washing cylinder 262 is firmly installed and avoids loosening during the cleaning process.

[0015] A socket 2638 is provided on the side of the rotating drum 25 near the mounting ring 261, corresponding to the position of the hollow tube 2631. A slot 2639 is provided on the inner wall of the socket 2638, and a locking block 2634 is provided in the middle of the slot 2639. After cleaning, the locking block 2634 of the disassembly rod 2632 is pressed in the opposite direction, causing the compression torsion spring 2635 to retract into the inner cavity 2633, so that the filter washing cylinder 262 can be pulled out from the rotating drum 25 and the residual impurities in the filter washing cylinder 262 can be directly cleaned. The filter cylinder tank 23 can be lifted by rotating the rotating rod 14 to facilitate the cleaning of the sediment in the tank and avoid the accumulation inside the equipment from affecting the subsequent cleaning effect.

[0016] The linkage assembly 27 includes a fixed plate 271 fixedly connected to the inner wall of the unopened side of the filter cartridge tank 23, a shaped rotating block 272 rotatably connected to the side of the fixed plate 271 near the filter washing cartridge 262, and a pulley 273 rotatably connected to the side of the fixed plate 271 away from the filter washing cartridge 262. The shaped rotating block 272 and the pulley 273 are interconnected inside the fixed plate 271. A second pulley 274 is rotatably connected to the inner wall of the tank 11 near the fixed plate 271. The second pulley 274 is located below the first pulley 273. The outer wall of the first pulley 273 is connected to the outer wall of the second pulley 274 through a shape memory metal strip 275. The pulleys 273 and 274 are interconnected and are located between the outer wall of the unopened side of the filter cartridge groove 23 and the inner wall of the groove box 11 near the fixed plate 271. The irregularly shaped rotating block 272 is located in the middle of the connecting groove 265. When the linkage component 27 is activated synchronously, the pulley 274 drives the memory metal belt 275 to rotate, causing the pulley 273 to rotate. The irregularly shaped rotating block 272 connected to the pulley 273 rotates accordingly. The irregularly shaped rotating block 272 is embedded in the connecting groove 265 of the filter washing cartridge 262, driving the filter washing cartridge 262 to rotate slowly in the rotating cylinder 25, so that the printed parts are in full contact with the cleaning liquid, improving the cleaning uniformity.

[0017] The vibration linkage mechanism 3 includes a receiving plate 31 fixedly connected to the left side of the frame 12, a hydraulic cylinder 32 rotatably connected to the left front end of the receiving plate 31, and a connecting arm 34 rotatably connected to the upper left side of the rear section of the receiving plate 31. A transfer arm 33 is rotatably connected to the other end of the connecting arm 34. One end of the transfer arm 33, away from the connecting arm 34, is rotatably connected to the end of the hydraulic cylinder 32, away from the front end of the receiving plate 31. The middle part of the transfer arm 33 is rotatably connected to the lower left rear end of the receiving plate 31. The rotating rod 14 is close to the receiving plate 31. One end is rotatably connected to the upper left rear end of the receiving plate 31. The vibration mechanism 3 is connected to start in conjunction with the cleaning process. The hydraulic cylinder 32 extends and retracts to push the adapter arm 33 to rotate around the hinge point of the receiving plate 31. The adapter arm 33 drives the connecting arm 34 to swing, which in turn drives the rotating rod 14 to rotate in the positioning block 15 of the positioning plate 13. The rotating rod 14 drives the main frame plate 21 and the filter cylinder groove 23 to generate slight vibration through the connecting plate 29, so that the loose impurities on the surface of the printed parts can be quickly removed, while avoiding the accumulation of impurities in the filter washing cylinder 262.

[0018] The lever control mechanism 4 includes a control rod 41 fixedly connected to the end of the rotating rod 14 away from the receiving plate 31 and an anti-slip sleeve 42 fixedly connected to the outer side of the control rod 41 away from the rotating rod 14. An anti-detachment ring 43 is provided on the left side of the end of the control rod 41 near the rotating rod 14. The middle part of the anti-detachment ring 43 is fixedly connected to the outer wall of the end of the rotating rod 14 near the control rod 41. If it is necessary to adjust the cleaning angle to adapt to the special structure of the printed parts, it can be operated through the lever control mechanism 4. Hold the anti-slip sleeve 42 and rotate the control rod 41 to drive the rotating rod 14 to rotate, thereby adjusting the tilt angle of the filter cylinder groove 23, so that the cleaning fluid can penetrate into the dead corner of the printed parts more easily. The anti-detachment ring 43 can prevent the control rod 41 from falling off during operation and ensure operational safety.

[0019] Working principle: When using this equipment, open the cover 264 of the cleaning component 26, place the 3D printed part to be processed into the filter washing cylinder 262, close the cover 264 to complete the seal, and fix the filter washing cylinder 262 to the rotating cylinder 25 through the mounting component 263. Align the hollow tube 2631 with the insertion hole 2638 of the rotating cylinder 25 and insert it. The locking block 2634 at the end of the disassembly rod 2632 pops out under the action of the torsion spring 2635 and locks into the slot 2639 on the inner wall of the insertion hole 2638. At the same time, the spring 2636, through the stabilizing block 2637, presses the disassembly rod 2632 to ensure that the filter washing cylinder 262 is firmly installed, preventing loosening during the cleaning process. Cleaning fluid is injected into the filter cartridge trough 23. The anti-splash frame 28 prevents liquid splashing during the cleaning process. The ultrasonic transducer 210 is activated, and ultrasonic vibration acts on the cleaning fluid to generate high-frequency pressure waves, which peel off impurities such as powder particles and resin residue from the surface of the printed parts. At the same time, it cleans the gaps and dead corners inside the complex structure. Simultaneously, the linkage component 27 is activated, and the second pulley drives the memory metal belt 275 to drive the first pulley 273 to rotate. The irregularly shaped rotating block 272 connected to the first pulley 273 rotates accordingly. The irregularly shaped rotating block 272 is embedded in the connecting groove 265 of the filter washing cartridge 262, driving the filter washing cartridge 262 to rotate slowly inside the rotating drum 25, so that the printed parts are fully cleaned. The contact with the cleaning fluid improves cleaning uniformity. The vibration mechanism 3, activated in conjunction with the cleaning process, causes the hydraulic cylinder 32 to extend and retract, pushing the adapter arm 33 to rotate around the hinge point of the receiving plate 31. The adapter arm 33 drives the connecting arm 34 to swing, which in turn drives the rotating rod 14 to rotate within the positioning block 15 of the positioning plate 13. The rotating rod 14, through the connecting plate 29, causes slight vibration in the main frame plate 21 and the filter cylinder groove 23, allowing loose impurities on the printed surface to quickly detach, while preventing impurities from accumulating in the filter cylinder 262. Manual adjustment of the angle is also possible. If the cleaning angle needs to be adjusted to suit specially structured printed parts, it can be operated via the lever control mechanism 4. Hold the protective... The sliding sleeve 42 rotates the control rod 41, causing the rotating rod 14 to rotate, thereby adjusting the tilt angle of the filter cylinder groove 23, making it easier for the cleaning fluid to penetrate into the dead corners of the printed parts. The anti-detachment ring 43 can prevent the control rod 41 from falling off during operation, ensuring operational safety. After cleaning, the locking block 2634 of the disassembly rod 2632 is pressed in the opposite direction, causing its compression torsion spring 2635 to retract into the inner cavity 2633, so that the filter washing cylinder 262 can be pulled out from the rotating cylinder 25 to directly clean the impurities remaining in the filter washing cylinder 262. The filter cylinder groove 23 can be lifted by rotating the rotating rod 14, making it convenient to clean the residue settled in the groove and avoid the accumulation inside the equipment affecting the subsequent cleaning effect.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
