Description

Technical Field

[0001] This utility model relates to the field of diamond wire production, specifically a sand-sweeping device for diamond wire production. Background Technology

[0002] Diamond wire is commonly used in silicon wafer cutting in the semiconductor industry. Currently, products produced using the suspension electroplating method have a good sand coating effect. However, the sand coating effect depends on the uniformity of particle dispersion in the sand coating solution. Usually, after the sand coating solution is initially stirred and added to the sand coating tank during the production process, it needs to be stirred again. Currently, the sand sweeping device used for the secondary stirring uses a single sand sweeping tube to work back and forth, which has low working efficiency and poor particle distribution uniformity. Utility Model Content

[0003] The purpose of this invention is to provide a sand-sweeping device for diamond wire production, so as to solve the problems mentioned in the background art.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

The other end of pipe 11 is connected to inlet pipe 3. One end of lower plating solution pipe 11 is fitted with a fixing block 13. Upper and lower sand-sweeping pipes 1 and 10 are set to move back and forth in the upper sand tank 14 to shorten the time of one sand-sweeping process and improve sand-sweeping efficiency. Upper and lower plating solution pipes 2 and 11 are set to input compressed plating solution into upper and lower sand-sweeping pipes 1 and 10, and at the same time drive upper and lower sand-sweeping pipes 1 and 10 to move in the upper sand tank 14. Inlet pipe 3 is set to connect with plating solution pump 15 to input compressed plating solution into upper and lower sand-sweeping devices. Fixing block 13 is set to be fixedly connected to upper and lower plating solution pipes 2 and 11 to transmit the movement of slider 5.
