Description

Technical Field

[0001] This utility model relates to the field of blue light 3D scanning technology, and in particular to an environmentally friendly auxiliary powder spraying system. Background Technology

[0002] Before performing 3D blue light scanning, spraying a developer onto the workpiece is a crucial preprocessing step that directly determines the quality of the final point cloud data. High-quality spraying can significantly enhance the contrast of the workpiece surface, optimize diffuse reflection, adapt to diverse materials, and effectively reduce environmental interference factors, thereby ensuring the generation of a high-quality 3D model. However, currently widely used developers lack self-volatility and may pose potential risks to the environment and human health. Therefore, the operation usually needs to be carried out manually in a well-ventilated environment.

[0003] However, in actual implementation, factors such as wind and temperature variations can easily lead to uneven spraying and inconsistent drying speeds. Therefore, it is necessary to design a pollution-resistant and interference-resistant powder coating system to improve coating quality and efficiency while reducing operational difficulty and risks.

[0045] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Please refer to Figures 1-9 An embodiment of this utility model provides an environmentally friendly auxiliary powder spraying system, comprising:

[0047] The air purification mechanism 3 includes an air intake chamber 31 and a negative pressure chamber 32. The side of the air intake chamber 31 near the negative pressure chamber 32 is provided with a powder spraying window 33 that communicates with the negative pressure chamber 32. The side of the air intake chamber 31 away from the negative pressure chamber 32 is provided with an air inlet 37. The side of the negative pressure chamber 32 away from the air intake chamber 31 is connected to an air extraction purifier 36.

[0048] The fixing mechanism 2 is located inside the negative pressure chamber 32 and includes several second fixing members 49 for fixing the corresponding plates 5. Each second fixing member 49 is used to pass through the mounting hole of the plate 5. A heater 34 is provided at the top of the negative pressure chamber 32 at the position corresponding to the plate 5.

[0049] The powder coating mechanism 1 is located inside the air inlet chamber 31 and is used to spray developer onto the side of the plate 5.

[0050] like Figure 1 and Figure 7 As shown, the fixing mechanism 2 and the powder spraying mechanism 1 are respectively set in the negative pressure chamber 32 and the air inlet chamber 31. The fixing mechanism 2 is used to fix the corresponding plate 5, and then the powder spraying mechanism 1 sprays the developer onto the plate 5. The gas inside the negative pressure chamber 32 is extracted by the air extraction and purification machine 36, which not only avoids the interference of external wind force changes on the spraying, but also effectively reduces dust emissions and reduces environmental pollution. In addition, the heater 34 can increase the temperature near the plate 5, accelerate the drying rate of the developer, and facilitate the better formation of the developer coating.

[0051] In some embodiments, the fixing mechanism 2 includes:

[0052] The rotating part, located at the bottom of the negative pressure chamber 32, includes a rotatable mounting turntable 21, the axis of which extends in a first direction; wherein, the first direction is... Figure 1 The vertical direction in the middle;

[0053] An electric arc-shaped slide 23 is mounted on a mounting turntable 21. The top of the slide seat of the electric arc-shaped slide 23 is provided with a mounting profile 24. The axis of the deflection shaft of the electric arc-shaped slide 23 is perpendicular to the first direction.

[0054] The first fastener 25 is detachably installed on the mounting profile 24, including a T-shaped frustum 252 provided on the mounting profile 24. The end of the T-shaped frustum 252 away from the mounting profile 24 is connected to a sleeve 253 via a universal joint 251. One end of the second fastener 49 is inserted into the sleeve 253.

[0055] like Figure 1 , Figure 4 and Figure 5 As shown, the fixing mechanism 2 clamps and fixes the plate 5 by fixing the second fixing member 49. During use, according to the position of the second fixing member 49 corresponding to the plate 5, the electric arc-shaped slide 23 is first installed on the top surface of the mounting turntable 21, and then the first fixing member 25 is installed on the mounting profile 24 via the T-shaped frustum 252. Further, the position of the sleeve 253 is adjusted via the universal joint 251 to ensure that each sleeve 253 can stably mount the second fixing member 49 on the plate 5. Furthermore, during powder coating, the electric arc-shaped slide 23 can drive the mounting mechanism 2 to clamp and fix the plate 5. The mounting profile 24 swings. In the initial state, the mounting profile 24 can swing to the left or right to spray the surface of the plate 5. Based on the initial state, it can drive the mounting turntable 21 to rotate, which drives the electric arc slide table 23, the mounting profile 24 and the plate 5 to rotate synchronously, so as to fully spray the surface of the plate 5 and carry out all-round spraying to reduce the spraying dead corners. Furthermore, the bottom of the negative pressure chamber 32 is also equipped with a rotary motor 22. The output shaft of the rotary motor 22 extends through into the inside of the negative pressure chamber 32 and is connected to the bottom of the mounting turntable 21 to drive the mounting turntable 21 to rotate.

[0056] In some embodiments, the powder coating mechanism 1 includes:

[0057] The three-axis moving part includes an X-axis linear module 11 located at the bottom of the air intake chamber 31, a Y-axis linear module 12 located on the slide of the X-axis linear module 11, and an electric lifter 13 located on the slide of the Y-axis linear module 12.

[0058] The tank fixing frame 14 is a C-shaped frame 141 located at the top of the movable column of the electric lifter 13. The powder spraying tank 15 is installed inside the C-shaped frame 141. A pressing motor 142 is provided at the top of the C-shaped frame 141. An adjusting stud 143 is provided at the output shaft end of the pressing motor 142 and extends through into the C-shaped frame 141. A pressing block 144 is connected to the middle of the adjusting stud 143 by a thread. One side surface of the pressing block 144 is in contact with the inner wall of the C-shaped frame 141, and the bottom end is in contact with the top of the powder spraying tank 15.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, the X-axis linear module 11, Y-axis linear module 12, and electric lifter 13 enable multi-position spraying adjustment. The pressing motor 142 drives the adjusting stud 143 to rotate, which in turn moves the pressing block 144 downward, pressing the nozzle at the top of the powder spraying tank 15 to automatically spray out the developer. Combined with the multi-directional adjustment function of the fixing mechanism 2, the automatic control system can achieve precise positioning and movement path planning for powder spraying, as well as adjust the position of the plate 5, reducing human error, ensuring high-quality spraying effect, and improving spraying efficiency.

[0060] In some embodiments, the second fastener 49 includes a first connecting seat 491 and a second connecting seat 493. The first connecting seat 491 is provided with a locking stud 492 near the end of the second connecting seat 493, and the second connecting seat 493 is provided with a screw hole 494 near the end of the first connecting seat 491. The locking stud 492 passes through the mounting hole and is threadedly connected to the screw hole 494.

[0061] like Figure 8 and Figure 9 As shown, taking a plate 5 as an example, the locking stud 492 is inserted through the mounting hole from the bottom of the plate 5, and then the screw hole 494 and the locking stud 492 are used from the top of the plate 5 to achieve the purpose of clamping the plate 5.

[0062] In some embodiments, the fixing mechanism 2 further includes a plurality of spare quick-release components 4, each spare quick-release component 4 being used for quick assembly and disassembly of a plate 5 of a specific size; for plate 5 with intersecting mounting hole axes, adjustment is required using the universal joint 251 in the fixing mechanism 2 to ensure the fixing of the plate 5. Figure 8 In the example of plate 5, the axes of each mounting hole are parallel to each other, and the spare quick-installation component 4 can be used, eliminating the need for universal angle adjustment and improving the efficiency of installation and fixing.

[0063] In some embodiments, the backup quick-install component 4 includes:

[0064] Mounting base 41 can be installed on the top of mounting turntable 21;

[0065] Angle adjustment section includes a first adjustment plate 42 that is rotatable at both ends of the mounting base 41. A second adjustment plate 43 is rotatably connected to each of the ends of the two first adjustment plates 42 that are away from the mounting base 41. A fixed plate 44 is rotatably connected between the ends of the two second adjustment plates 43 that are away from the first adjustment plates 42. The axes of rotation of the mounting base 41, the first adjustment plates 42, the second adjustment plates 43 and the fixed plate 44 are all parallel to each other.

[0066] The spacing adjustment part includes a damping limiting cylinder 45 located in the middle of the fixed plate 44, and a spacing adjustment rod 46 penetrating the inside of the damping limiting cylinder 45. The spacing adjustment rod 46 is provided with a plurality of branch rods 48 at the end away from the mounting base 41, and each branch rod 48 is provided with a second fixing member 49 at the end away from the spacing adjustment rod 46.

[0067] like Figure 1 and Figure 6 As shown, based on the mounting base 41, the height of the second adjusting plate 43 and the fixed plate 44 is adjusted by rotating the first adjusting plate 42. Based on the first adjusting plate 42, the rotation of the second adjusting plate 43 ensures that the side surface of the fixed plate 44 is parallel to the vertical direction, and the spacing adjustment rod 46 is perpendicular to the side surface of the fixed plate 44. At this time, the extension direction of each second fixing member 49 is parallel to the vertical direction, ensuring that the second fixing member 49 can quickly install the plate 5 with the axes of each mounting hole parallel to each other.

[0068] To ensure stable installation, two spare quick-installation components 4 can be set. By pushing the spacing adjustment rod 46, the spacing between adjacent spare quick-installation components 4 can be adjusted to ensure that the second fixing component 49 can correspond to the mounting hole. In use, first remove the second connecting seat 493, align the mounting hole of the plate 5 with the locking stud 492 of the first connecting seat 491, and vertically lower the plate 5 so that the locking stud 492 passes through the mounting hole. Then install the second connecting seat 493 to complete the quick fixing of the plate 5 of special specifications. Compared with the universal joint 251, which requires repeated adjustment, the plate 5 with parallel axes of each mounting hole can be quickly fixed and installed using the spare quick-installation components 4. Optionally, the end of the spacing adjustment rod 46 away from the branch rod 48 is provided with an operating plate 47. Pushing the operating plate 47 can drive the spacing adjustment rod 46 to move, and then, under the restriction of the damping limit cylinder 45, drive the branch rod 48 to move away from the mounting seat 41.

[0069] Furthermore, the damping limit cylinder 45 has a rubber ring embedded inside, and there is a high friction between the spacing adjustment rod 46 and the rubber ring. After the spacing adjustment rod 46 moves, there will be no positional displacement without the action of external force.

[0070] In some embodiments, one end of the air extraction purifier 36 is connected to the end of the negative pressure chamber 32 away from the air inlet chamber 31 via the air extraction pipe 35, and a baffle 38 is provided inside the negative pressure chamber 32 between the air extraction pipe 35 and the fixing mechanism 2.

[0071] like Figure 1 and Figure 7 As shown, a baffle 38 is provided between the exhaust pipe 35 and the fixing mechanism 2. The baffle 38 can block some dust, improve the filtration efficiency of the exhaust purifier 36, and avoid direct airflow, thus reducing airflow interference caused by the exhaust purifier 36.

[0072] In some embodiments, the bottom of the air intake chamber 31 is provided with a first frame 61, and the bottom of the negative pressure chamber 32 is provided with a second frame 62 to ensure the installation of the air intake chamber 31 and the negative pressure chamber 32. In addition, the middle of the second frame 62 is provided with a storage plate for temporary storage of the spare quick-installation component 4 and the air extraction and purification machine 36.

[0073] In some embodiments, the mounting turntable 21 is provided with a plurality of threaded holes evenly distributed on it, and the electric arc slide 23 and the mounting base 41 can be selected to be adjusted and installed in corresponding positions to ensure installation flexibility.
