Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and more specifically, to a 3D printed workpiece cleaning device. Background Technology

[0002] After the 3D printing photopolymerization machine finishes printing the workpiece, it is necessary to clean the workpiece. Common cleaning methods include soaking, rinsing with running water, and ultrasonic cleaning.

[0003] In existing technologies, when cleaning workpieces using immersion washing, the cleaning solution in the cleaning tank needs to be changed after cleaning several workpieces; otherwise, subsequent workpieces will not be thoroughly cleaned. However, existing immersion washing equipment has a slow cleaning solution replacement process, and after the used cleaning solution is discharged, the inner wall of the cleaning tank needs to be manually rinsed to ensure all cleaning solution is removed. However, manually holding the water hose for rinsing is inefficient and does not clean thoroughly. In addition, the wastewater from rinsing is pumped through a water pump and pipe to a waste liquid tank located at a distance, making it difficult to monitor the amount of liquid in the waste liquid tank. To prevent waste liquid overflow, it is necessary to check it manually periodically, which greatly reduces production efficiency.

[0004] Therefore, it is necessary for the inventors to design a new 3D printed workpiece cleaning device to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a 3D printed workpiece cleaning device to solve the problems of low efficiency and difficulty in controlling the liquid level in the waste liquid tank when manually rinsing the cleaning tank wall in related technologies.

[0006] To achieve the above objectives, this application provides a 3D printed workpiece cleaning device, including a cleaning tank body, a waste liquid tank, and water pipes;

[0007] The top of the cleaning tank body is rotatably equipped with a cover plate, and a water inlet and a liquid inlet are fixedly installed on the cover plate;

[0008] A fixing plate is detachably connected to the top of the waste liquid tank, and a first detection element for detecting the liquid level in the waste liquid tank is fixedly installed at the bottom of the fixing plate.

[0009] One end of the water pipe is fixedly connected to the bottom of the washing tub body, and the other end of the water pipe is fixedly connected to the fixing plate. A water pumping assembly is also fixedly installed on the water pipe.

[0010] Preferably, the water pumping assembly includes a solenoid valve, a flow switch, and a water pump. The solenoid valve and the flow switch are located at one end near the main body of the cleaning tank, and the water pump is located at one end near the fixed plate.

[0011] Preferably, the first detection element is an acoustic wave sensor, which is directly opposite the inner bottom surface of the waste liquid tank.

[0012] Preferably, the bottom of the cover plate has a limiting ring that is adapted to the body of the washing tub, and a handle is fixedly provided in the middle of the top of the cover plate.

[0013] Preferably, the water inlet is inclined on the cover plate, and the water outlet direction of the water inlet is towards the inner wall of the cleaning tub body.

[0014] Preferably, the bottom of the cleaning tub body has a conical part, and a water outlet is fixedly provided at the bottom of the conical part, and the water pipe is fixedly connected to the water outlet.

[0015] Preferably, two arc-shaped plates are fixedly disposed at the bottom of the fixing plate, and the side wall of the waste liquid tank is clamped between the two arc-shaped plates.

[0016] Preferably, the top of the fixing plate is fixedly provided with a coupling interface, and the end of the water pipe is fixedly connected to the coupling interface.

[0017] The 3D printed workpiece cleaning equipment provided by this utility model has the following advantages compared with the prior art:

[0018] By rotating the cover during rinsing with clean water, the clean water pipe remains stable, preventing any leakage into the inner wall of the cleaning tank. Furthermore, the presence of a first detection element that monitors the liquid level in the waste tank in real time effectively prevents overflow and eliminates the need for regular worker checks, thus improving production efficiency.

[0030] like Figures 1 to 3 As shown, a 3D printed workpiece cleaning device includes a cleaning tank body 1, a waste liquid tank 2, and a water pipe 3. A cover plate 4 is rotatably installed on the top of the cleaning tank body 1, and a water inlet 5 and a liquid inlet 6 are fixedly installed on the cover plate 4. A fixing plate 7 is detachably connected to the top of the waste liquid tank 2, and a first detection element 8 for detecting the liquid level in the waste liquid tank 2 is fixedly installed at the bottom of the fixing plate 7. One end of the water pipe 3 is fixedly connected to the bottom of the cleaning tank body 1, and the other end of the water pipe 3 is fixedly connected to the fixing plate 7. A water pumping assembly is also fixedly installed on the water pipe 3.

[0031] Specifically, after the cover plate 4 is closed, cleaning fluid is introduced into the cleaning tank body 1 through the liquid inlet 6. The cover plate 4 prevents liquid from splashing out when the cleaning fluid is introduced. An observation window can also be set on the cover plate 4 to observe the liquid level in the cleaning tank body 1. Then, the workpiece is placed into the cleaning tank for soaking and cleaning. When the cleaning fluid needs to be replaced, the dirty cleaning fluid is pumped into the waste liquid tank 2 through the water pumping component. The first detection element 8 is used to detect the liquid level in the waste liquid tank 2 to prevent liquid overflow. The first detection element 8 is electrically connected to the water pumping component. When the first detection element 8 detects that the liquid level is too high, the water pumping component will automatically stop working. After the waste liquid tank 2 is replaced, the rinsing and pumping work will be carried out again. After all the cleaning fluid in the cleaning tank body 1 has been pumped out, the inner wall needs to be rinsed with clean water. At this time, the clean water pipe 3 is connected to the water inlet 5. While the clean water is introduced, the cover plate 4 is rotated. When the cover plate 4 has rotated 360 degrees, it can be ensured that the inner wall of the cleaning tank body 1 is rinsed. It is efficient and stable and can be operated by a single person.

[0032] In this embodiment, by setting the cover plate 4 to rotate, the water pipe 3 can remain stable during rinsing with clean water, and the inner wall of the cleaning tank will not be leaked. Furthermore, by setting the first detection element 8 to detect the liquid level in the waste liquid tank 2 in real time, the overflow of liquid in the waste liquid tank 2 is effectively avoided, and workers do not need to check it regularly, thus improving production efficiency.

[0033] The water pumping assembly includes a solenoid valve 9, a flow switch 10, and a water pump 11. The solenoid valve 9 and the flow switch 10 are located at one end near the cleaning tank body 1, and the water pump 11 is located at one end near the fixing plate 7. Specifically, the solenoid valve 9 controls the flow of water in the water pipe 3. When the solenoid valve 9 is open, the cleaning fluid can be drawn out; when the solenoid valve 9 is closed, the cleaning fluid cannot be drawn out, allowing for soaking and cleaning. The flow switch 10 detects whether the cleaning fluid has been completely drawn out; if it has, the water pump 11 is turned off.

[0034] The first detection element 8 is an acoustic sensor, which is directly opposite the inner bottom surface of the waste liquid tank 2. The acoustic sensor can detect the liquid level in the waste liquid tank 2 in real time. In addition, laser sensors, electromagnetic sensors, and other devices that can detect liquid level can also be used here.

[0035] The bottom of the cover plate 4 has a limiting ring 12 that is adapted to the washing tub body 1, and a handle 13 is fixedly provided in the middle of the top of the cover plate 4. Specifically, the limiting ring 12 prevents the cover plate 4 from shifting when it rotates, and the handle 13 makes it easy for the user to hold.

[0036] The water inlet 5 is inclined on the cover plate 4, and the water outlet direction of the water inlet 5 is towards the inner wall of the cleaning tub body 1. Specifically, the inclined water inlet 5 can make the water flow impact force stronger and the rinsing effect better.

[0037] The bottom of the cleaning tub body 1 has a conical portion 101, and a water outlet is fixedly provided at the bottom of the conical portion 101. The water pipe 3 is fixedly connected to the water outlet. Specifically, the conical portion 101 allows the liquid in the cleaning tub body 1 to flow out easily, reducing liquid residue.

[0038] Two arc-shaped plates 14 are fixedly installed at the bottom of the fixing plate 7, and the side wall of the waste liquid tank 2 is clamped between the two arc-shaped plates 14. Specifically, the method of using two arc-shaped plates 14 to clamp the side of the waste liquid tank 2 is extremely convenient, simple in structure, and very low in cost.

[0039] The top of the fixing plate 7 is fixedly provided with a coupling interface 15, and the end of the water pipe 3 is fixedly connected to the coupling interface 15. Specifically, a thread can be provided on the coupling interface 15 to achieve the connection between the water pipe 3 and the coupling interface 15.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
