Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a powder cleaning and reversing tool. Background Art

[0002] In the field of 3D printing technology, after printing, some unmelted metal or non-metal powder adheres to the surface of the workpiece. If this powder is not cleaned in time, it will seriously affect the surface quality of the workpiece, resulting in a significant increase in surface roughness, which will not meet the requirements of high-precision parts for smoothness. Subsequent finishing processes such as grinding may be required, increasing costs and time. On the other hand, the residual powder may fall off during subsequent assembly and use, causing wear and contamination to other components, and even affecting the performance and reliability of the entire system.

[0003] Therefore, there is an urgent need for a powder cleaning tool to efficiently clean the powder adhering to the surface of the workpiece, thereby improving the overall quality and practicality of 3D printed workpieces. Utility Model Content

[0021] Based on the above technical solution, this utility model can produce at least the following technical effects:

[0022] The powder cleaning and reversing fixture provided by this utility model uses a hoisting assembly to hoist and move a substrate carrying a workpiece. During the hoisting process, a portion of the powder falls into the powder collection box under the action of gravity and is collected.

[0023] Meanwhile, a pneumatic vibrator is installed on the lower end face of the substrate. After the lifting assembly lifts the substrate to the second position, the pneumatic vibrator is activated to remove the remaining powder adhering to the surface of the workpiece and collect it in the powder collection box.
