Description

Technical Field

[0001] This application relates to the field of 3D printing, specifically to a 3D printing post-processing workstation. Background Technology

[0002] See Figure 1 and Figure 2 ,like Figure 1 As shown, in the prior art, a 3D printing post-processing workstation 1 is used to post-process a mobile printing carriage 2 that holds printing material and 3D printed parts, in order to remove the 3D printed parts from the printing material and recycle the printing material. Specifically, the mobile printing carriage 2 has a carrier that extends and retracts in the vertical direction, forming a 3D printing structure space on the carrier, in which the 3D printed parts and printing material are housed. The 3D printing post-processing workstation 1 includes a worktable 3, a door 4, a shield 5, and a recycling device 6. The worktable 3 has a receiving cavity 7 for accommodating the mobile printing carriage 2, and the upper surface of the worktable 3 is flush with or slightly higher than the upper surface of the mobile printing carriage 2. The receiving cavity 7 has a transfer port for the mobile printing carriage 2 to move in or out. The door 4 is rotatably or slidably connected to the worktable 3 for opening or closing the transfer port. The shield 5 covers the worktable 3, and an operating area 8 is formed between the shield 5 and the upper surface of the worktable 3. Figure 2 As shown, the recycling device 6 includes a recycling pipe 9, a recycling tank 10, and a suction pump 11 connected by pipelines. The suction pump 11 draws printing material from the recycling pipe 9 into the recycling tank 10 from the mobile printing cart 2 by creating a negative pressure.

[0003] When the 3D printing post-processing workstation 1 processes the 3D printed parts and printing materials contained in the structure space of the mobile printing carriage 2, the operator stands outside the door 4, holding the recovery tube 9. Using the negative pressure within the recovery tube 9, the operator sucks away the printing material, exposing the 3D printed parts and allowing them to be removed. While the operator is sucking away the printing material with one hand holding the recovery tube 9, they often need to use the other hand to grab any potentially clumped printing material. Because the printing material easily reverts from a clumped state to a powdery state, it easily disperses in the operating area 8, causing significant pollution to the operator's working environment and making their working conditions extremely harsh. Operators must wear masks during operation; otherwise, prolonged work can easily lead to pneumoconiosis, causing irreversible damage to their health. Summary of the Invention

[0004] The purpose of this application is to overcome the aforementioned defects or problems in the prior art and to provide a 3D printing post-processing workstation that can improve the working environment and operating conditions of operators compared to the prior art.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] The first technical solution relates to a 3D printing post-processing workstation for post-processing a mobile printing carriage containing printing material and 3D printed parts, so as to remove the 3D printed parts from the printing material and recycle the printing material. The 3D printing post-processing workstation includes a workbench, a door, and a recycling device. The workbench has a receiving cavity for receiving the mobile printing carriage, and the receiving cavity has a transfer port for the mobile printing carriage to move in or out. The door is connected to the workbench and is used to open or close the transfer port. The recycling device includes a recycling pipe, a recycling tank, and a suction pump connected by a pipeline. The suction pump draws the printing material in the mobile printing carriage from the recycling pipe to the recycling tank by forming a negative pressure. The recycling device further includes a first recycling section, which is fixed to the door and has a first suction port. The first suction port opens at the upper end of the door. The suction pump also draws the printing material sucked in from the first suction port to the recycling tank by forming a negative pressure.

[0007] The second technical solution is based on the first technical solution, wherein the first suction port is adapted to be close to the front side of the mobile printing vehicle when the mobile printing vehicle is moved into the accommodating cavity and the door closes the transfer port.

[0008] The third technical solution is based on the first technical solution, wherein the first suction port is arranged facing upwards.

[0009] The fourth technical solution is based on the first technical solution, wherein the first suction port faces upwards from the accommodating cavity.

[0010] The fifth technical solution is based on the first technical solution, wherein the recycling device further includes a second recycling section and a third recycling section; the second recycling section and the third recycling section are respectively fixed to the left and right sides of the workbench adjacent to the accommodating cavity and are respectively provided with a second suction port and a third suction port, the second suction port and the third suction port are both open at the upper end of the workbench, and the suction pump also draws the printing material sucked in from the second suction port and the third suction port into the recycling tank by forming a negative pressure.

[0011] The sixth technical solution is based on the fifth technical solution, wherein the second suction port and the third suction port are arranged facing upwards.

[0012] The seventh technical solution is based on the fifth technical solution, wherein the second suction port and the third suction port face upwards from the accommodating cavity.

[0013] The eighth technical solution is based on the fifth technical solution, wherein the recycling device further includes a fourth recycling section, the fourth recycling section is fixed to the rear side of the workbench adjacent to the accommodating cavity and is provided with a fourth suction port, the fourth suction port is opened at the upper end of the workbench, and the suction pump also draws the printing material sucked in from the fourth suction port into the recycling tank by forming a negative pressure.

[0014] The ninth technical solution is based on the eighth technical solution, wherein the fourth suction port is arranged facing upwards.

[0015] The tenth technical solution is based on the eighth technical solution, wherein the fourth suction port faces upwards from the accommodating cavity.

[0016] Compared with existing technologies, the above solution has the following beneficial effects:

[0017] In the first technical solution, the first recycling section is fixed to the door body, and the first suction port opens at the upper end of the door body. The suction pump draws the printing material sucked in from the first suction port into the recycling tank by forming a negative pressure. It can draw the printing material scattered in the operating area into the recycling tank outside the recycling pipe, effectively reducing the dust concentration in the operating area and improving the working environment and operating conditions of the operators compared with the existing technology.

[0018] In the second technical solution, the first suction port is located near the front of the mobile printing carriage when the mobile printing carriage moves into the accommodating cavity and the door is closed, thereby forming a negative pressure air curtain between the operator and the operating area, effectively reducing the possibility of the operator inhaling dust.

[0019] In the third technical solution, the first suction port is set upward so that the upper surface of the workstation and the door can be flush with the upper surface of the mobile printing cart, thus avoiding fatigue for the operator due to raising their hands too high during operation.

[0020] In the fourth technical solution, the first suction port faces upwards from the receiving cavity, which can more effectively suction the printing material in the operating area.

[0021] The fifth technical solution further enhances the suction of printing material in the operating area by adding a second, third, and fourth recovery section, making the printing material less likely to scatter in the operating area and more effectively improving the operating environment and conditions.

[0022] In the eighth technical solution, the first suction port, the second suction port, the third suction port, and the fourth suction port are arranged around the mobile printing vehicle, which can maximize the suction of printing material scattered in the operating area, thus significantly improving the working environment and operating conditions of the operators compared with the existing technology.

[0023] The technical effects of the sixth and ninth technical solutions are comparable to those of the third technical solution.

[0024] The technical effects of the seventh and tenth technical solutions are comparable to those of the fourth technical solution. Attached Figure Description

[0039] The technical solutions in the embodiments will now be clearly and completely described with reference to the accompanying drawings.

[0040] Example 1

[0041] See Figure 3 , Figure 3 The overall structure of the 3D printing post-processing workstation 1 in this embodiment is shown. For example... Figure 1 As shown, the 3D printing post-processing workstation 1 is used to post-process the mobile printing carriage 2, which contains printing material and 3D printed parts, to remove the 3D printed parts from the printing material and recycle the printing material. Specifically, the mobile printing carriage 2 has a carrier that extends and retracts in the vertical direction, forming a 3D printing structure space on the carrier. The 3D printed parts and printing material are housed in the structure space. The 3D printing post-processing workstation 1 includes a worktable 3, a door 4, a shield 5, and a recycling device 6. The worktable 3 has a receiving cavity 7 for accommodating the mobile printing carriage 2, and the upper surface of the worktable 3 is flush with or slightly higher than the upper surface of the mobile printing carriage 2. The receiving cavity 7 has a transfer port for the mobile printing carriage 2 to move in or out. The door 4 is rotatably or slidably connected to the worktable 3 for opening or closing the transfer port. The shield 5 covers the worktable 3, and an operating area 8 is formed between the shield 5 and the upper surface of the worktable 3.

[0042] See Figure 4 , Figure 4 The overall structure of the recycling device 6 in this embodiment is shown. For example... Figure 4 As shown, the recycling device 6 includes a recycling pipe 9, a first recycling section 12, a second recycling section 13, a third recycling section 14, a fourth recycling section 15, a recycling tank 10, and a suction pump 11. The suction pump 11 draws printing material from the recycling pipe 9, the first recycling section 12, the second recycling section 13, the third recycling section 14, and the fourth recycling section 15 into the recycling tank 10 by creating a negative pressure. The recycling pipe 9 can be a retractable serpentine tube.

[0043] See Figure 3 and Figure 5 , Figure 5 The upper surfaces of the workbench 3 and the door 4 in this embodiment are shown. For example... Figure 3 and Figure 5 As shown, the first collection section 12 is fixed to the door 4 and has a first suction port 12a, which opens at the upper end of the door 4 and faces upward. The first suction port 12a is adapted to be close to the front side of the mobile printing carriage 2 and extend in the left-right direction when the mobile printing carriage 2 is moved into the receiving cavity 7 and the door 4 closes the transfer port. The second collection section 13 and the third collection section 14 are respectively fixed to the left and right sides of the worktable 3 adjacent to the receiving cavity 7 and have corresponding second suction ports 13a and third suction ports 14a. Both the second suction ports 13a and the third suction ports 14a open on the upper surface of the worktable 3 and face upward. Both the second suction ports 13a and the third suction ports 14a extend in the front-back direction. The fourth collection section 15 is fixed to the rear side of the worktable 3 adjacent to the receiving cavity 7 and has a fourth suction port 15a, which opens on the upper surface of the worktable 3 and faces upward. The fourth suction port 15a extends in the left-right direction.

[0044] In this embodiment, the upper surface of the workbench 3 and the upper surface of the door 4 are both flush with the upper surface of the mobile printing vehicle 2.

[0045] In this embodiment, since the first recycling section 12 is fixed to the door body 4 and the first suction port 12a opens at the upper end of the door body 4, the suction pump 11 draws the printing material sucked in from the first suction port 12a into the recycling tank 10 by forming a negative pressure. This can draw the printing material scattered in the operating area 8 into the recycling tank 10 outside the recycling pipe 9, effectively reducing the dust concentration in the operating area 8 and improving the working environment and operating conditions of the operators compared to the prior art.

[0046] In this embodiment, the first suction port 12a is close to the front side of the mobile printing carriage 2 when the mobile printing carriage 2 moves into the accommodating cavity 7 and the door 4 is closed, thereby forming a negative pressure air curtain between the operator and the operating area 8, effectively reducing the possibility of the operator inhaling dust.

[0047] In this embodiment, the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a are arranged facing upwards, so that the upper surfaces of the workstation 3 and the door 4 can be flush with the upper surface of the mobile printing vehicle 2, avoiding fatigue for the operator due to raising their hands too high during operation.

[0048] In this embodiment, the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a are arranged around the mobile printing carriage 2, which can maximize the suction of printing material scattered in the operating area 8, thus significantly improving the working environment and operating conditions of the operator compared to the prior art.

[0049] Example 2

[0050] See Figure 6 , Figure 6 A cross-sectional view of the 3D printing post-processing workstation 1 in this embodiment is shown. For example... Figure 6 As shown, the only difference between this embodiment and Embodiment 1 is that the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a are no longer upward-facing, but are all inclined towards the upper part of the receiving cavity 7. That is, the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a are all inclined towards the upper surface of the moving printing carriage 2 in a downward direction. At this time, the upper surface of the worktable 3 and the upper surface of the door 4 are higher than the upper surface of the moving printing carriage 2.

[0051] In this embodiment, the first suction port 12a, the second suction port 13a, the third suction port 14a and the fourth suction port 15a all face upwards of the accommodating cavity 7, which can more effectively suck up the printing material in the operating area 8 and most significantly improve the working environment and operating conditions of the operator.

[0052] In other embodiments, as one of the preferred arrangements where the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a face upward toward the accommodating cavity 7, the first suction port 12a, the second suction port 13a, the third suction port 14a, and the fourth suction port 15a may also be arranged vertically.

[0053] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
