[0002] Diamond wire is a wire cutting tool made by electrodeposition process with steel wire as the matrix and diamond powder as the abrasive. Steel wire is mainly used for cutting high-hardness and brittle materials such as crystalline silicon, sapphire, and precision ceramics. Sand equipment is the most important link in the production process of electroplated diamond wire. Whether it can complete the sanding task quickly, evenly, continuously and stably is an important indicator to measure the quality of electroplated diamond wire equipment. Most of the sand adding devices used in the current diamond wire production rely on manual timed addition, which is inefficient. Moreover, manual sand adding cannot be quantitative, which can easily cause too much or too little sand adding, resulting in waste. Therefore, we propose an automatic sand adding device for diamond wire production. Utility Model Content
