Description

Technical Field

[0001] This utility model belongs to the field of 3D printing equipment technology, and in particular relates to a 3D printed parts cleaning tank. Background Technology

[0002] 3D printing, also known as additive manufacturing technology, is an advanced manufacturing technology that creates three-dimensional objects by depositing materials layer by layer based on digital models. Since its inception, 3D printing technology has achieved rapid development due to its significant advantages of not requiring complex molds, being able to quickly form and achieve personalized customization. After 3D printing is completed, uncured resin, support material or other impurities usually remain on the surface of the printed parts. These residues will affect the appearance and performance of the printed parts, so the printed parts need to be cleaned.

[0003] Currently, manual wiping or soaking cleaning methods cannot effectively remove residues inside complex structures, especially for printed parts with deep holes, blind holes, or fine features. Rigid brushes can easily scratch the surface of printed parts, which is particularly noticeable for printed parts with thin-walled structures or fine features. Existing equipment usually only provides a single cleaning function and cannot simultaneously meet multiple needs such as rinsing, bubble oscillation, and drying.

[0004] To address these issues, we provide a 3D printed part cleaning tank. Utility Model Content

[0005] The purpose of this invention is to provide a 3D printed part cleaning tank. By combining cleaning components and a placement mechanism, it solves the problem that existing cleaning methods, which rely on manual wiping or soaking, cannot effectively remove residues inside complex structures and can only provide a single cleaning function.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a cleaning tank for 3D printed parts, including a base plate. A cleaning box is fixedly connected to the top of the base plate. A combined cleaning assembly is fixedly connected to one side of the top of the cleaning box. The inner cavity of the cleaning box is provided with a placement mechanism. The combined cleaning assembly includes a shell, one side of which is fixedly connected to the cleaning box. A first motor is fixedly connected to one side of the inner cavity of the shell. A worm gear is fixedly connected to the output end of the first motor. A lead screw is movably connected to one side of the inner cavity of the shell via a bearing. A worm wheel is fixedly connected to the front end of the lead screw, and the worm wheel meshes with the worm gear. A movable frame is threaded onto the surface of the lead screw. A connecting seat is fixedly connected to the top of the movable frame. A spray pipe is fixedly connected to one side of the top of the connecting seat. A spray nozzle is connected to the bottom of the spray pipe. A jet pipe is fixedly connected to the other side of the top of the connecting seat. The bottom of the jet pipe is connected to a blower head. When the first motor drives the worm to rotate, the horizontal rotational motion is converted into the axial rotation of the lead screw through the meshing transmission between the worm wheel and the worm. The thread on the surface of the lead screw engages with the thread inside the moving frame, causing the moving frame to reciprocate linearly along the axis of the lead screw. The spray pipe is connected to an external cleaning fluid supply device through a hose. The jet pipe is connected to a compressed air source. The blower head adopts a conical design, which can concentrate the airflow and improve the drying efficiency. The worm and worm wheel transmission have self-locking characteristics, which can prevent the moving frame from being displaced due to external forces, ensuring the stability of the nozzle and blower head position during the cleaning process. The nozzle sprays the cleaning fluid onto the surface of the printed parts, and in conjunction with the reciprocating motion of the moving frame, achieves cleaning without dead angles.

[0008] The present invention is further configured such that the placement mechanism includes a placement frame, a connecting block is fixedly connected to one side of the placement frame, a second motor is fixedly connected to one side of the top of the cleaning tank, a threaded rod is fixedly connected to the output end of the second motor, a threaded sleeve is threadedly connected to the surface of the threaded rod, and one side of the threaded sleeve is fixedly connected to the connecting block. The second motor drives the threaded rod to rotate, and through the linkage between the threaded sleeve and the connecting block, the vertical lifting and lowering of the placement frame is realized, adjusting the height position of the printed parts in the cleaning tank, which facilitates the loading and unloading of materials by the operator. By adjusting the height of the placement frame, the depth of the printed parts immersed in the cleaning liquid can be flexibly controlled, or the distance between the printed parts and the nozzle or blower head can be adjusted during the spraying and drying stages to achieve the purpose of draining, controlling water and drying quickly.

[0009] The present invention is further configured such that a bubble generator is fixedly connected to the surface of the cleaning tank, and a control panel is fixedly connected to one side of the surface of the bubble generator. The bubble generator generates dense microbubbles through microporous aeration technology. The impact force generated by the bursting of the bubbles during their ascent can penetrate into the deep holes, gaps and other complex structures of the printed parts, peel off and remove residual impurities. The operating parameters of the bubble generator are controlled by the control panel.

[0010] The present invention is further configured such that a bracket is fixedly connected to the bottom of the inner cavity of the placement rack, and the number of brackets is three. The three brackets can stably support the printed parts, ensuring the stability of the printed parts during the cleaning process.

[0011] The present invention is further configured such that a sliding groove is provided on one side of the top of the cleaning tank, the inner cavity of the sliding groove is slidably connected to the moving frame, and the sliding groove cooperates with the slider to provide guidance for the reciprocating motion of the combined cleaning components, ensuring that the nozzle and the blower head move smoothly along a straight line and improving the uniformity of cleaning coverage.

[0012] The present invention is further provided that a maintenance plate is provided on one side of the outer shell, and fasteners are provided at the four corners of the surface of the maintenance plate. The maintenance plate is fixed by the fasteners and can be quickly disassembled, which facilitates the operator to troubleshoot the fault.

[0013] The present invention is further configured such that a limiting groove is provided on one side of the inner wall of the cleaning tank, and a slider that cooperates with the limiting groove is fixedly connected to one side of the placement rack. The slider moves inside the limiting groove to limit the placement rack, ensuring that the placement rack moves in a straight line along the inner wall of the cleaning tank, thus ensuring the stability of the placement rack.

[0014] The present invention is further configured such that a partition is fixedly connected to the bottom of the inner cavity of the outer shell, and the inner cavity of the partition is movably connected to the worm through a bearing. The partition fixes one end of the worm through the bearing, forming a two-point support structure with the bearing at the other end, thereby reducing the radial runout of the worm when rotating at high speed and improving the stability of the meshing between the worm and the worm wheel.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a transmission mechanism driven by a first motor to drive a worm gear and a worm wheel, which in turn drives the lead screw to rotate and cause the moving frame to reciprocate. This enables the spray pipe and the air jet pipe to work together. High-pressure water flows through the nozzle to rinse the surface of the printed parts, removing larger particles of impurities. The high-pressure airflow provided by the blower head quickly dries the printed parts after cleaning, reducing drying time. At the same time, the microbubbles generated by the bubble generator burst during their ascent, forming micro-impacts that can thoroughly remove residues in deep holes, blind holes, and fine structures, significantly improving cleaning quality.

[0017] 2. This utility model uses a combination of a threaded rod and a threaded sleeve driven by a second motor to automatically adjust the height of the placement rack. After completing the bubble cleaning, the rack is drained to facilitate subsequent rinsing and drying, achieving all-round cleaning of the printed parts without dead angles. The three brackets can support the printed parts and ensure the stability of the printed parts during the cleaning process. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5This utility model is a 3D printed part cleaning tank, including a base plate 1, a cleaning box 2 fixedly connected to the top of the base plate 1, a combined cleaning component 3 fixedly connected to one side of the top of the cleaning box 2, a placement mechanism 4 provided in the inner cavity of the cleaning box 2, the combined cleaning component 3 including a shell 31, one side of the shell 31 fixedly connected to the cleaning box 2, a first motor 32 fixedly connected to one side of the inner cavity of the shell 31, a worm gear 33 fixedly connected to the output end of the first motor 32, a lead screw 34 movably connected to one side of the inner cavity of the shell 31 through a bearing, a worm wheel 35 fixedly connected to the front end of the lead screw 34, the worm wheel 35 meshing with the worm gear 33, a movable frame 36 threadedly connected to the surface of the lead screw 34, a connecting seat 37 fixedly connected to the top of the movable frame 36, a spray pipe 38 fixedly connected to one side of the top of the connecting seat 37, a nozzle 39 connected to the bottom of the spray pipe 38, an air jet pipe 310 fixedly connected to the other side of the top of the connecting seat 37, and a blower head 311 connected to the bottom of the air jet pipe 310.

[0028] Specifically: When the first motor 32 drives the worm 33 to rotate, the horizontal rotational motion is converted into the axial rotation of the lead screw 34 through the meshing transmission between the worm wheel 35 and the worm 33. The thread on the surface of the lead screw 34 engages with the thread inside the moving frame 36, causing the moving frame 36 to reciprocate linearly along the axis of the lead screw 34. The spray pipe 38 is connected to an external cleaning fluid supply device through a hose, and the air jet pipe 310 is connected to a compressed air source. The blow nozzle 311 adopts a conical design, which can concentrate the airflow to improve the drying efficiency. The worm 33 and worm wheel 35 transmission have self-locking characteristics, which can prevent the moving frame 36 from being displaced due to external forces, ensuring the stability of the position of the nozzle 39 and the blow nozzle 311 during the cleaning process. The nozzle 39 sprays the cleaning fluid onto the surface of the printed parts, and together with the reciprocating motion of the moving frame 36, achieves cleaning without dead angles.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the placement mechanism 4 includes a placement rack 41, a connecting block 42 fixedly connected to one side of the placement rack 41, a second motor 43 fixedly connected to one side of the top of the cleaning tank 2, a threaded rod 44 fixedly connected to the output end of the second motor 43, a threaded sleeve 45 threadedly connected to the surface of the threaded rod 44, one side of the threaded sleeve 45 fixedly connected to the connecting block 42, a bubble generator 5 fixedly connected to the surface of the cleaning tank 2, a control panel 6 fixedly connected to one side of the surface of the bubble generator 5, and the inner cavity of the placement rack 41... The bottom is fixedly connected with a bracket 7, and there are three brackets 7. A sliding groove 8 is opened on one side of the top of the cleaning box 2. The inner cavity of the sliding groove 8 is slidably connected to the moving frame 36. A maintenance plate 9 is provided on one side of the outer shell 31. Fasteners are provided at the four corners of the surface of the maintenance plate 9. A limiting groove 10 is opened on one side of the inner wall of the cleaning box 2. A slider 11 that cooperates with the limiting groove 10 is fixedly connected to one side of the placement frame 41. A partition 12 is fixedly connected to the bottom of the inner cavity of the outer shell 31. The inner cavity of the partition 12 is movably connected to the worm gear 33 through a bearing.

[0031] Specifically: The second motor 43 drives the threaded rod 44 to rotate, and through the linkage of the threaded sleeve 45 and the connecting block 42, the vertical lifting of the placement rack 41 is realized, adjusting the height of the printed parts in the cleaning tank 2, which is convenient for operators to load and unload. By adjusting the height of the placement rack 41, the depth of the printed parts immersed in the cleaning solution can be flexibly controlled, or the distance between it and the nozzle 39 and the blower head 311 can be adjusted during the spraying and drying stages to achieve the purpose of draining water and rapid drying. The bubble generator 5 generates dense microbubbles through microporous aeration technology. The impact force generated by the bursting of the bubbles during their rise can penetrate deep into the complex structures such as deep holes and gaps in the printed parts, peeling off and removing residual impurities. The operating parameters of the bubble generator 5 are controlled by the control panel 6, and the three brackets 7 can stably support the printed parts. The support ensures the stability of the printed parts during the cleaning process. The slide 8 and the slider 11 cooperate to guide the reciprocating motion of the combined cleaning assembly 3, ensuring that the nozzle 39 and the blower head 311 move smoothly in a straight line, improving the uniformity of the cleaning coverage. The inspection plate 9 is fixed by fasteners and can be quickly disassembled, which is convenient for operators to troubleshoot. The slider 11 moves inside the limiting groove 10, which can limit the placement frame 41 and ensure that the placement frame 41 moves in a straight line along the inner wall of the cleaning box 2, ensuring the stability of the placement frame 41. The partition plate 12 fixes one end of the worm gear 33 with the bearing and forms a two-point support structure with the bearing at the other end, reducing the radial runout of the worm gear 33 when rotating at high speed, and improving the stability of the meshing between the worm gear 33 and the worm wheel 35.

[0032] The working principle of this utility model is as follows: The 3D printed part is placed on the bracket 7 inside the placement frame 41. Then, the second motor 43 is started, which drives the threaded rod 44 to rotate. The threaded rod 44 drives the threaded sleeve 45 to move up and down along the axis of the threaded rod 44, thereby realizing the vertical lifting and lowering of the placement frame 41. The height position of the printed part in the cleaning box 2 can be flexibly adjusted, making it easy for operators to complete the loading and unloading operations. At the same time, according to the needs of different cleaning stages, such as adjusting the distance between the printed part and the nozzle 39 during spray cleaning, and adjusting the distance between the printed part and the blower head 311 during the drying stage, the best cleaning and drying effect can be achieved.

[0033] The bubble generator 5 uses microporous aeration technology to generate dense microbubbles through the uniformly distributed micropores on its surface. These bubbles gradually burst as they rise in the cleaning fluid, and the resulting impact force can penetrate deep into the complex structures such as deep holes and crevices of the printed parts, effectively peeling off and removing stubborn residual impurities. Operators can precisely adjust the working parameters of the bubble generator 5, such as the amount and frequency of bubble generation, through the control panel 6 to adapt to the cleaning needs of different types of printed parts and further improve the cleaning effect.

[0034] Once the placement frame 41 is adjusted to the appropriate position, the first motor 32 is started. The first motor 32 drives the worm gear 33 to rotate. Through the meshing transmission between the worm wheel 35 and the worm gear 33, the horizontal rotational motion of the first motor 32 is converted into the axial rotation of the lead screw 34. The rotation of the lead screw 34 drives the moving frame 36 to make linear reciprocating motion along the axis of the lead screw 34. During the movement of the moving frame 36, the spray pipe 38 and the air jet pipe 310 move synchronously. The spray pipe 38 is connected to the external cleaning fluid supply equipment through a hose. When the moving frame 36 moves, the nozzle 39 sprays the cleaning fluid onto the surface of the printed parts, effectively washing away larger particulate impurities and some residues attached to the surface of the printed parts.

[0035] After the spray cleaning stage is completed, the jet pipe 310 starts to work. The jet pipe 310 is connected to a compressed air source, and the blow nozzle 311 sprays out the compressed air in a concentrated manner to form a strong airflow. Driven by the moving frame 36, the blow nozzle 311 quickly dries the cleaning liquid remaining on the surface of the printed parts, shortens the drying time, and improves the cleaning efficiency.

[0036] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
