Description

Technical Field

[0001] This invention relates to the field of post-processing technology for 3D printing, and more particularly to a cleaning device for 3D printed parts. Background Technology

[0002] 3D printing is a technology that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. 3D printing can produce high-quality parts. During the printing process, dust, glue residue, or other unwanted protrusions may accumulate on the parts. These residues can affect the appearance and performance of the parts, thus requiring cleaning. Proper cleaning can eliminate layer lines, spots, and support marks generated during printing, thereby improving the surface finish and overall quality of the parts. Cleaning typically involves rinsing the parts with soapy water or isopropyl alcohol (IPA), which helps remove surface glue residue, small spots, and other unwanted protrusions.

[0003] There are still some shortcomings in the current technology for cleaning 3D printed parts:

[0004] 1. After 3D printing is completed, staff usually need to remove the parts from the printing tray and then clean them manually. However, during manual cleaning, excessive force may be used, causing damage or discoloration to the parts.

[0005] 2. When cleaning the parts, workers need to carefully remove the supporting material on the parts using tools such as fingers, needle-nose pliers, putty knives or carving knives. Separating the parts from the supporting material is time-consuming and laborious, and can easily damage the parts.

[0006] 3. After 3D printing, the parts need to be manually removed and cleaned, which has a low degree of automation and makes it difficult to carry out large-scale 3D printing.

[0007] To address the aforementioned problems, this invention proposes a cleaning device for 3D printed parts. Summary of the Invention

[0008] The purpose of this invention is to solve the shortcomings of existing manual cleaning methods, such as damage or discoloration of parts, time-consuming and labor-intensive separation of parts from support materials, and low degree of automation, and to propose a cleaning device for 3D printed parts.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A cleaning device for 3D printed parts includes a base, a 3D printing device is fixed to one side of the top of the base, the 3D printing device is used to print parts, and a placement plate is placed on the support plate of the 3D printing device, and the parts are printed on the placement plate.

[0011] A first groove is located on the top side of the base. A cleaning cylinder is fixed to the bottom inner wall of the first groove, and the parts are placed in the cleaning cylinder for cleaning. The cleaning cylinder contains cleaning liquid. A liquid storage ring is slidably connected to the inner wall of the cleaning cylinder through a sliding groove and a slider. A cleaning ring is located at the bottom of the liquid storage ring. An annular slide rail is fixed to the top of the cleaning ring, and the cleaning ring is slidably connected to the bottom of the liquid storage ring through the annular slide rail. The bottom of the liquid storage ring and the top of the cleaning ring are slidably connected in a sealed manner. Multiple first electromagnetic nozzles are provided inside the cleaning ring for cleaning the outer wall of the parts from different angles.

[0012] A rotating disk rotates on the bottom inner wall of the cleaning cylinder via a rotating column. The rotating disk has multiple flow holes and is used to drive the cleaning ring to move up and down. A second electromagnetic nozzle is provided on the top of the rotating disk for cleaning the bottom of the parts. A sliding strip is slidably connected to the top of the rotating disk, and the sliding strip is used to drive the second electromagnetic nozzle to swing back and forth.

[0013] Two shovels, both of which slide into the cleaning cylinder and have their tops flush with the top of the cleaning cylinder, are used to remove and separate parts from the placement plate.

[0014] The first cleaning structure, located on top of the rotating disk, is used to control the reciprocating movement of the cleaning ring to clean the parts from multiple angles.

[0015] The second cleaning structure is located on the top of the rotating disk and is used to drive the second electromagnetic nozzle to swing and clean the bottom of the parts from multiple angles.

[0016] Two sets of separation structures are set on the top of the base, and the two sets of separation structures are located on both sides of the cleaning cylinder, which are used to drive the shovel to move and complete the separation operation of the placement plate and the parts.

[0017] In one possible design, the first cleaning structure includes multiple nut blocks rotatably connected to the top of a rotating disk. A first gear is fixed to the outer wall of each nut block. An internal gear ring located above the rotating disk is fixed to the inner wall of the cleaning cylinder, and the internal gear ring meshes with the first gear. Multiple Z-shaped rods are fixed to the bottom of the cleaning ring. The bottom ends of the Z-shaped rods pass through corresponding nut blocks and extend to the bottom of the rotating disk. The outer wall of each Z-shaped rod has a reciprocating thread section, and the Z-shaped rod is threadedly connected to the nut block through the reciprocating thread section. The rotating disk is driven to rotate by a motor, and the rotating disk drives the cleaning ring to rotate via the Z-shaped rods. Since the first gear meshes with the internal gear ring, the first gear drives the nut blocks to rotate under the action of the internal gear ring. The nut blocks are threadedly connected to the Z-shaped rods through the reciprocating thread section. Therefore, while the rotating disk drives the Z-shaped rods and the cleaning ring to rotate, the up-and-down reciprocating movement of the cleaning ring can be controlled, completing the cleaning operation of the parts without manual intervention and ensuring the integrity of the parts.

[0018] In one possible design, the second cleaning structure includes a rotating shaft that rotates on top of a rotating disk via a base plate. A second electromagnetic nozzle is fixedly sleeved on the outer wall of the rotating shaft. A second gear is fixedly sleeved on the outer wall of the rotating shaft. A torsion spring, fixedly connected to the second electromagnetic nozzle, is sleeved on the outer wall of the second gear. The end of the torsion spring away from the second electromagnetic nozzle is fixedly connected to the base plate. A plurality of racks are provided at the top of the sliding bar, and these racks intermittently mesh with the second gear. The interaction between the racks, the second gear, and the torsion spring drives the second electromagnetic nozzle to reciprocate. A connecting rod is rotatably connected to one side of the top of the sliding bar. A pin rotates through the connecting rod, and one end of the pin is fixedly connected to one of the Z-shaped rods. When the Z-shaped rod moves up and down, it drives the connecting rod to rotate via the pin, which in turn pushes the sliding bar to reciprocate. The multiple racks on the sliding bar intermittently mesh with the second gear. Therefore, the interaction between the racks, the second gear, and the torsion spring enables the second electromagnetic nozzle to reciprocate, thus effectively cleaning the bottom or center of the components. This allows for cleaning of the components without manual intervention, ensuring their integrity.

[0019] In one possible design, the separation structure includes a second groove on the top of the base, which communicates with the first groove. A movable plate is slidably connected to the top of the base via a slide rail. Two support legs are slidably connected to the top of the movable plate via sliders and grooves. The bottom of the shovel plate is fixedly connected to the top of the two support legs. A fixed plate is fixed to the bottom of the movable plate. An electric push rod is fixed in the second groove via a horizontal plate. The output shaft of the electric push rod is fixedly connected to the fixed plate. Multiple arc-shaped blocks are provided on both sides of the movable plate, and the arc-shaped blocks are fixed to the top of the base. Sliding blocks are slidably connected to both sides of the movable plate, and the bottom of the sliding blocks is arc-shaped. The sliding blocks cooperate with the arc-shaped blocks. Two springs are fixed to both sides of the movable plate via fixed platforms. Connecting plates are fixed to both sides of the two sliding blocks, and the bottom ends of the multiple springs are respectively fixedly connected to the top of the corresponding connecting plates. The sliding block, arc-shaped block, and spring work together to drive the sliding block to move back and forth. Each of the two support legs has an inclined groove, and each of the two inclined grooves has a pin slidably engaged within it. The ends of the two pins, which are far apart from each other, are fixedly connected to the corresponding sliding blocks. The pins and inclined grooves work together to drive the scraper to move back and forth linearly. The output shaft of the electric push rod pushes the moving plate and scraper towards the center of the cleaning cylinder. The two scrapers work together to remove and separate the parts adhering to the placement plate. During separation, the support legs drive the scraper to move back and forth a short distance, ensuring that the parts are not damaged during separation. When the moving plate moves, the sliding block moves back and forth under the action of the arc-shaped block and the spring. The up-and-down movement of the sliding block, through the engagement of the inclined groove and the pin, drives the support legs to move back and forth, thus removing parts over a short distance and ensuring the integrity of the separated parts. The separation of parts can be completed without manual intervention.

[0020] In one possible design, the bottom of the liquid storage ring and the top of the cleaning ring are provided with multiple connecting holes, and the liquid storage ring and the cleaning ring are intermittently connected through the multiple connecting holes for injecting cleaning fluid into the cleaning ring. A water pump is fixed to one side of the cleaning cylinder, the inlet end of the water pump is connected to the cleaning cylinder through a pipe, and the outlet end of the water pump is fixed with a hose, the tip of the hose extending into the cleaning cylinder and connected to the liquid storage ring. The cooperation of the water pump and the hose is used to pump the cleaning fluid in the cleaning cylinder into the liquid storage ring, providing sufficient cleaning fluid for the subsequent first electromagnetic nozzle.

[0021] In one possible design, a rubber baffle is fixed to the top of the rotating disk by multiple support rods. The rubber baffle is used to support fallen parts. The rubber baffle has a circular hole inside, which provides clearance for the swinging of the second electromagnetic nozzle. The top of the second electromagnetic nozzle is lower than the top of the rubber baffle. When the second electromagnetic nozzle swings to clean the bottom of the parts, the circular hole makes way, preventing the rubber baffle from obstructing the water jet sprayed by the second electromagnetic nozzle. When the shovel completes the separation of the parts from the placement plate, the parts fall onto the rubber baffle, making it easier for the first electromagnetic nozzle to clean the top of the parts later.

[0022] In one possible design, the shovel plate has an inclined surface on the side near the cleaning cylinder to allow the shovel plate to smoothly separate the parts on the placement plate.

[0023] In one possible design, a ring magnet is fixedly embedded at the bottom of the placement plate, and the support plate inside the 3D printing equipment is made of metal. The placement plate generates magnetic attraction with the support plate through the ring magnet, which can prevent the placement plate from shifting during the printing of parts.

[0024] In one possible design, the number of the first electromagnetic nozzles is at least six, with the water outlets of two first electromagnetic nozzles placed horizontally, the water outlets of another two first electromagnetic nozzles placed obliquely upward, and the water outlets of the last two first electromagnetic nozzles placed obliquely downward; when the cleaning ring rotates and moves up and down, the multi-angle arrangement of the multiple first electromagnetic nozzles can fully clean the outer layer of the components.

[0025] In one possible design, a base is fixed to the top of the base, and a rotating shaft is rotatably connected within the base, located between the cleaning cylinder and the base. Two rotating cylinders are fixed to the outer wall of the rotating shaft, and a cylindrical tube is rotatably connected to one end of each rotating cylinder. A drive motor is fixed inside each rotating cylinder, and the output shaft of the drive motor is fixedly connected to one end of the cylindrical tube. A circular plate is slidably connected inside the cylindrical tube via a groove and a slider. A screw is fixed to one side of the circular plate, and one end of the screw extends to one side of the rotating cylinder. A screw threadedly connected to the screw is fixed to one end of the rotating cylinder. The placement plate has two insertion holes on the side near the cleaning cylinder that mate with the screw. The drive motor drives the cylinder to rotate, and the cylinder drives the screw to rotate through the circular plate. The screw is threadedly connected to a nut at one end of the rotating cylinder. The screw moves towards the placement plate until the screw thread extends into the insertion hole. The placement plate and the rotating cylinder are fixed by the engagement of the screw and the insertion hole. Then, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating cylinder to rotate 180°. At this time, the placement plate is just stuck on the top of the cleaning cylinder, and the parts on the placement plate are located inside the cleaning cylinder. The parts can be moved without manual intervention.

[0026] Beneficial effects:

[0027] In this invention, the first cleaning structure includes multiple nut blocks rotatably connected to the top of a rotating disk. A first gear is fixed to the outer wall of each of the nut blocks. An internal gear ring located above the rotating disk is fixed to the inner wall of the cleaning cylinder. The outer wall of the Z-shaped rod has a reciprocating thread section, and the Z-shaped rod is threadedly connected to the nut blocks through the reciprocating thread section. The rotating disk drives the cleaning ring to rotate via the Z-shaped rod, and the first gear meshes with the internal gear ring. Therefore, the first gear drives the nut blocks to rotate under the action of the internal gear ring. Thus, during the rotation of the Z-shaped rod and the cleaning ring by the rotating disk, the up-and-down reciprocating movement of the cleaning ring can be controlled, allowing for the cleaning of components without manual intervention and ensuring the integrity of the components.

[0028] In this invention, a second gear is fixedly sleeved on the outer wall of the rotating shaft, and multiple racks are provided on the top of the sliding bar. A connecting rod rotates on the top of the sliding bar, and the connecting rod is rotatably connected to one of the Z-shaped rods through a pin. When the Z-shaped rod moves up and down, it pushes the sliding bar to move back and forth through the pin and the connecting rod. The multiple racks on the sliding bar intermittently mesh with the second gear. Therefore, through the cooperation of the racks, the second gear, and the torsion spring, the second electromagnetic nozzle can swing back and forth, thereby fully cleaning the bottom or center of the parts. The cleaning operation of the parts can be completed without manual intervention, ensuring the integrity of the parts.

[0029] In this invention, the top of the movable plate is slidably connected to the shovel plate via two support legs. Multiple arc-shaped blocks are provided on both sides of the movable plate, and sliding blocks are slidably connected to both sides. Each of the two support legs has an inclined groove, and a pin is slidably engaged within each of the inclined grooves. The ends of the two pins, which are far apart from each other, are respectively fixedly connected to the corresponding sliding blocks. The sliding blocks reciprocate up and down under the action of the arc-shaped blocks and springs. Through the cooperation of the inclined grooves and pins, the sliding blocks can drive the support legs to reciprocate, thereby enabling the removal of parts over a short distance, ensuring the integrity of the parts separation, and allowing the parts separation operation to be completed without manual intervention.

[0030] In this invention, one end of each of the two rotating cylinders is rotatably connected to a cylindrical tube. A circular plate slides inside the cylindrical tube, and a screw is fixed to one side of the circular plate, with one end of the screw extending to one side of the rotating cylinder. A nut is fixed to one end of the rotating cylinder and threadedly connected to the screw. When the cylinder rotates, it drives the screw to rotate through the circular plate. Under the action of the nut, the screw moves towards the placement plate. The screw is fixedly connected to the placement plate through a hole. Then, a motor drives the rotating shaft to rotate, which in turn drives the rotating cylinder to rotate 180°. At this point, the placement plate is just stuck on the top of the cleaning cylinder, and the parts on the placement plate are located inside the cleaning cylinder, allowing the parts to be moved without manual intervention.

[0031] In this invention, after 3D printing is completed, the placement plate can be automatically clamped onto the cleaning cylinder, at which point the part is located inside the cleaning cylinder. Then, the outer layer and bottom of the part can be automatically cleaned, resulting in a very thorough cleaning. After cleaning, the part can be automatically and safely separated from the placement plate. The entire process of handling, cleaning, and separating the part requires no manual operation, has a high degree of automation, and greatly improves the cleaning efficiency of the part.

Detailed Implementation

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Example 1

It includes a base 1, a 3D printing device 2 is fixed on one side of the top of the base 1, the 3D printing device 2 is used to print parts, and a placement plate 3 is placed on the support plate of the 3D printing device 2, and the parts are printed on the placement plate 3.

[0047] Reference Figure 2 The bottom of the placement plate 3 is fixedly embedded with a ring magnet 4. The support plate inside the 3D printing equipment 2 is made of metal. The placement plate 3 generates magnetic attraction with the support plate through the ring magnet 4, which can prevent the placement plate 3 from shifting when printing parts.

[0048] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6The first groove 5 is located on the other side of the top of the base 1. A cleaning cylinder 6 is fixed to the bottom inner wall of the first groove 5, and the parts are placed in the cleaning cylinder 6 for cleaning. The cleaning cylinder 6 contains cleaning liquid. A liquid storage ring 7 is slidably connected to the inner wall of the cleaning cylinder 6 through a sliding groove and a slider. A cleaning ring 9 is located at the bottom of the liquid storage ring 7. An annular slide rail 8 is fixed to the top of the cleaning ring 9, and the cleaning ring 9 is slidably connected to the bottom of the liquid storage ring 7 through the annular slide rail 8. The bottom of the liquid storage ring 7 and the top of the cleaning ring 9 are slidably connected in a sealed manner. Multiple first electromagnetic nozzles 11 are provided inside the cleaning ring 9 for cleaning the outer wall of the parts from different angles.

[0049] Reference Figure 4 and Figure 6 The number of first electromagnetic nozzles 11 is at least 6, with the water outlet ends of two first electromagnetic nozzles 11 placed horizontally, the water outlet ends of the other two first electromagnetic nozzles 11 placed obliquely upward, and the water outlet ends of the last two first electromagnetic nozzles 11 placed obliquely downward; when the cleaning ring 9 rotates and moves up and down, the multi-angle arrangement of multiple first electromagnetic nozzles 11 can fully clean the outer layer of the parts.

[0050] Reference Figure 4 , Figure 6 and Figure 7 The rotating disk 14 rotates on the bottom inner wall of the cleaning cylinder 6 via a rotating column. The rotating disk 14 is provided with multiple flow holes. The rotating disk 14 is used to drive the cleaning ring 9 to move up and down. The top of the rotating disk 14 is provided with a second electromagnetic nozzle 21 for cleaning the bottom of the parts. The top of the rotating disk 14 is slidably connected with a sliding strip 24, which is used to drive the second electromagnetic nozzle 21 to swing back and forth.

[0051] Reference Figure 4 , Figure 6 and Figure 7 A rubber baffle 28 is fixed to the top of the rotating disk 14 by multiple support rods. The rubber baffle 28 is used to support fallen parts. The rubber baffle 28 has a round hole 29 inside, which provides clearance for the swing of the second electromagnetic nozzle 21. The top height of the second electromagnetic nozzle 21 is lower than the top height of the rubber baffle 28. When the second electromagnetic nozzle 21 swings to clean the bottom of the parts, the round hole 29 makes way to prevent the rubber baffle 28 from obstructing the water jet sprayed by the second electromagnetic nozzle 21. When the shovel plate 35 completes the separation of the parts from the placement plate 3, the parts fall onto the rubber baffle 28, which makes it easier for the first electromagnetic nozzle 11 to clean the top of the parts later.

[0052] Reference Figures 1-3 Two scraper plates 35 are slidably extended into the cleaning cylinder 6, and the top of the scraper plates 35 is flush with the top of the cleaning cylinder 6, for scraping and separating the parts on the placement plate 3.

A water pump 12 is fixed on one side of the cleaning cylinder 6. The inlet end of the water pump 12 is connected to the cleaning cylinder 6 through a pipe, and the outlet end of the water pump 12 is fixed with a hose 13. The top end of the hose 13 extends into the cleaning cylinder 6 and is connected to the liquid storage ring 7. The cooperation of the water pump 12 and the hose 13 is used to pump the cleaning fluid in the cleaning cylinder 6 into the liquid storage ring 7, so as to provide sufficient cleaning fluid for the first electromagnetic nozzle 11 in the later stage.

[0055] Reference Figures 3-7 The device also includes a first cleaning structure located on top of the rotating disk 14, used to control the reciprocating movement of the cleaning ring 9 to clean parts from multiple angles. The first cleaning structure includes multiple nut blocks 17 rotatably connected to the top of the rotating disk 14, with a first gear 16 fixed to the outer wall of each nut block 17. An internal gear ring 15 located above the rotating disk 14 is fixed to the inner wall of the cleaning cylinder 6, and the internal gear ring 15 meshes with the first gear 16. Multiple Z-shaped rods 18 are fixed to the bottom of the cleaning ring 9, with the bottom ends of the Z-shaped rods 18 passing through the corresponding nut blocks 17 and extending to the bottom of the rotating disk 14. The outer wall of the Z-shaped rods 18 is provided with... The device has a reciprocating thread section 19, and the Z-shaped rod 18 is threadedly connected to the nut block 17 through the reciprocating thread section 19. The rotating disk 14 is driven to rotate by a motor. The rotating disk 14 drives the cleaning ring 9 to rotate through the Z-shaped rod 18. The first gear 16 meshes with the internal gear ring 15. Therefore, the first gear 16 drives the nut block 17 to rotate under the action of the internal gear ring 15. The nut block 17 is threadedly connected to the Z-shaped rod 18 through the reciprocating thread section 19. Therefore, while the rotating disk 14 drives the Z-shaped rod 18 and the cleaning ring 9 to rotate, the cleaning ring 9 can also be controlled to move up and down reciprocally. The cleaning operation of the parts can be completed without manual intervention, ensuring the integrity of the parts.

[0056] Reference Figure 2 , Figure 6 and Figure 7The device also includes a second cleaning structure disposed on the top of the rotating disk 14, used to drive the second electromagnetic nozzle 21 to swing and clean the bottom of the parts from multiple angles.

The second electromagnetic nozzle 21 is fixedly sleeved on the outer wall of the rotating shaft 20. A second gear 22 is fixedly sleeved on the outer wall of the rotating shaft 20. A torsion spring 23 fixedly connected to the second electromagnetic nozzle 21 is sleeved on the outer wall of the second gear 22, and the end of the torsion spring 23 away from the second electromagnetic nozzle 21 is fixedly connected to the base plate. The top of the sliding bar 24 is provided with multiple racks 25, and the multiple racks 25 intermittently mesh with the second gear 22. The cooperation of the racks 25 with the second gear 22 and the torsion spring 23 is used to drive the second electromagnetic nozzle 21 to swing and clean the bottom of the parts from multiple angles. The second electromagnetic nozzle 21 reciprocates. A connecting rod 27 is rotatably connected to the top side of the sliding bar 24. The connecting rod 27 rotates through a pin 26, and one end of the pin 26 is fixedly connected to one of the Z-shaped rods 18. When the Z-shaped rod 18 moves up and down, it drives the connecting rod 27 to rotate through the pin 26. The connecting rod 27 pushes the sliding bar 24 to move back and forth. Multiple racks 25 on the sliding bar 24 intermittently mesh with the second gear 22. Therefore, through the cooperation of the racks 25, the second gear 22, and the torsion spring 23, the second electromagnetic nozzle 21 can reciprocate, thereby fully cleaning the bottom or center of the parts. The cleaning operation of the parts can be completed without manual intervention, ensuring the integrity of the parts.

[0057] Reference Figure 3 , Figure 8 and Figure 9The device also includes two sets of separation structures located on the top of the base 1, with the two sets of separation structures situated on either side of the cleaning cylinder 6. These structures are used to drive the shovel plate 35 to move and complete the separation of the placement plate 3 from the parts. The separation structure includes a second groove 30 located on the top of the base 1, which is connected to the first groove 5. A movable plate 33 is slidably connected to the top of the base 1 via a slide rail. Two support legs 34 are slidably connected to the top of the movable plate 33 via a slider and a slide groove. The bottom of the shovel plate 35 is fixedly connected to the top of the two support legs 34. The bottom of the movable plate 33... A fixed plate 32 is fixedly mounted. An electric push rod 31 is fixed in the second groove 30 via a horizontal plate. The output shaft of the electric push rod 31 is fixedly connected to the fixed plate 32. Multiple arc-shaped blocks 41 are provided on both sides of the movable plate 33, and the arc-shaped blocks 41 are fixed to the top of the base 1. Sliding blocks 38 are slidably connected to both sides of the movable plate 33, and the bottom of the sliding blocks 38 is arc-shaped. The sliding blocks 38 cooperate with the arc-shaped blocks 41. Two springs 40 are fixed to both sides of the movable plate 33 via a fixed platform. Connecting plates 39 are fixed to both sides of the two sliding blocks 38, and multiple springs 40 are connected to the base 1. The bottom ends of the 0 are fixedly connected to the top of the corresponding connecting plates 39. The cooperation of the sliding block 38, the arc block 41 and the spring 40 can drive the sliding block 38 to move up and down reciprocally. Each of the two support legs 34 is provided with a groove 36, and a pin 37 is slidably engaged in each of the two grooves 36. The ends of the two pins 37 that are far apart from each other are fixedly connected to the corresponding sliding blocks 38. The cooperation of the pins 37 and the grooves 36 can drive the shovel plate 35 to move back and forth linearly. The output shaft of the electric push rod 31 pushes the moving plate 33 and the shovel plate 35 to move towards the center of the cleaning cylinder 6. The two scraper plates 35 work together to remove and separate the parts that are stuck to the placement plate 3. During separation, the support leg 34 drives the scraper plates 35 to move back and forth a short distance, thus ensuring that the parts are not damaged during separation. When the moving plate 33 moves, the sliding block 38 moves up and down under the action of the arc block 41 and the spring 40. The up and down movement of the sliding block 38 can drive the support leg 34 to move back and forth through the cooperation of the inclined groove 36 and the pin 37, thus removing the parts over a short distance and ensuring the integrity of the parts separation. The parts separation operation can be completed without manual intervention.

[0058] Example 2

[0059] refer to Figure 10 and Figure 11An improvement based on embodiment 1: A base 42 is fixed to the top of the base 1. A rotating shaft 43 is rotatably connected inside the base 42, and the rotating shaft 43 is located between the cleaning cylinder 6 and the base 1. Two rotating cylinders 44 are fixed to the outer wall of the rotating shaft 43. A cylinder 45 is rotatably connected to one end of each of the two rotating cylinders 44. A drive motor 47 is fixed inside the rotating cylinder 44. The output shaft of the drive motor 47 is fixedly connected to one end of the cylinder 45. A circular plate 46 is slidably connected inside the cylinder 45 through a sliding groove and a slider. A screw 48 is fixed to one side of the circular plate 46, and one end of the screw 48 extends to one side of the rotating cylinder 44. A nut threadedly connected to the screw 48 is fixed to one end of the rotating cylinder 44. The placement plate 3 is placed against... Two insertion holes 49 are provided on one side near the cleaning cylinder 6 to cooperate with the screw 48; the drive motor 47 drives the cylinder 45 to rotate, and the cylinder 45 drives the screw 48 to rotate through the circular plate 46. The screw 48 is threadedly connected to the nut at one end of the rotating cylinder 44. The screw 48 moves towards the placement plate 3 until the screw 48 thread extends into the insertion hole 49. The placement plate 3 and the rotating cylinder 44 are fixed by the cooperation of the screw 48 and the insertion hole 49. Then, the motor drives the rotating shaft 43 to rotate, and the rotating shaft 43 drives the rotating cylinder 44 to rotate 180°. At this time, the placement plate 3 is just stuck on the top of the cleaning cylinder 6, and the parts on the placement plate 3 are located inside the cleaning cylinder 6. The parts can be moved without manual intervention.

[0060] A method for using a cleaning device for 3D printed parts includes the following steps:

[0061] S1. Place the placement plate 3 on the support plate inside the base 1, with the insertion hole 49 aligned with the screw 48. The support plate of the base 1 is made of metal. The magnetic attraction between the ring magnet 4 and the support plate allows the placement plate 3 to be placed stably on the support plate. When the part is printed on the placement plate 3, the drive motor 47 drives the cylinder 45 to rotate. The cylinder 45 drives the screw 48 to rotate through the circular plate 46. The screw 48 is threadedly connected to the nut at one end of the rotating cylinder 44. The screw 48 moves towards the placement plate 3 until the screw 48 thread extends into the insertion hole 49. The placement plate 3 and the rotating cylinder 44 are fixed by the cooperation of the screw 48 and the insertion hole 49. Then, the motor drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the rotating cylinder 44 to rotate 180°. At this time, the placement plate 3 is just stuck on the top of the cleaning cylinder 6, and the part on the placement plate 3 is located inside the cleaning cylinder 6. The part can be moved without manual intervention.

[0062] S2. Pump 12 pumps the cleaning fluid in the cleaning cylinder 6 into the storage ring 7 through the hose 13. The storage ring 7 is slidably connected to the top of the cleaning ring 9. The storage ring 7 is intermittently connected to the cleaning ring 9 through the connecting hole 10. Therefore, the cleaning fluid in the storage ring 7 is injected into the cleaning ring 9 through the connecting hole 10. Then, the parts are rinsed by multiple first electromagnetic nozzles 11. Since two of the six parts are rinsed horizontally, two are rinsed diagonally upwards, and the last two are rinsed diagonally downwards, the parts can be thoroughly cleaned during the up-and-down reciprocating movement of the cleaning ring 9. The surface is rinsed; the rotating disk 14 is driven by a motor to rotate, and the rotating disk 14 drives the cleaning ring 9 to rotate through the Z-shaped rod 18. The first gear 16 meshes with the internal gear ring 15. Therefore, the first gear 16 drives the nut block 17 to rotate under the action of the internal gear ring 15. The nut block 17 is threadedly connected to the Z-shaped rod 18 through the reciprocating thread section 19. Therefore, while the rotating disk 14 drives the Z-shaped rod 18 and the cleaning ring 9 to rotate, the cleaning ring 9 can also be controlled to move up and down reciprocally. The cleaning operation of the parts can be completed without manual intervention, ensuring the integrity of the parts.

[0063] S3. When cleaning the surface of the parts, it can also clean the bottom or center of the parts. When the Z-shaped rod 18 moves up and down, the Z-shaped rod 18 drives the connecting rod 27 to rotate through the pin 26. The connecting rod 27 pushes the sliding bar 24 to move back and forth. The multiple racks 25 on the sliding bar 24 intermittently mesh with the second gear 22. Therefore, through the cooperation of the racks 25, the second gear 22 and the torsion spring 23, the second electromagnetic nozzle 21 can swing back and forth, so as to fully clean the bottom or center of the parts. The cleaning operation of the parts can be completed without manual labor, ensuring the integrity of the parts.

[0064] S4. When cleaning is completed, the output shaft of the electric push rod 31 pushes the moving plate 33 and the scraper 35 to move towards the center of the cleaning cylinder 6. The two scrapers 35 work together to remove and separate the parts stuck to the placement plate 3. During separation, the support leg 34 drives the scraper 35 to move back and forth a short distance, thus ensuring that the parts are not damaged during separation. When the moving plate 33 moves, the sliding block 38 moves up and down under the action of the arc block 41 and the spring 40. The up and down movement of the sliding block 38 can drive the support leg 34 to move back and forth through the cooperation of the inclined groove 36 and the pin 37, thus removing the parts over a short distance and ensuring the integrity of the parts separation. The parts separation operation can be completed without manual intervention.

[0065] S5. The separated parts fall onto the rubber baffle 28, which is used to support the parts. At this time, the cleaning ring 9 moves up and down again, and the first electromagnetic nozzle 11, which is angled downward, can clean the top of the parts. The handling, cleaning and separation do not require manual operation, and the automation is extremely high, which improves the efficiency of 3D printed parts.

[0066] However, as is well known to those skilled in the art, the working principles and wiring methods of the 3D printing equipment 2, drive motor 47, second electromagnetic nozzle 21, first electromagnetic nozzle 11 and water pump 12 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
