TECHNICAL FIELD

[0002] The single crystal furnace conductive slip ring is a component in the single crystal furnace, which is mainly used for conveying raw materials and shaped single crystal materials. The single crystal furnace conductive slip ring is usually composed of a cylindrical metal ring body, and the surface is covered with conductive material (such as copper, aluminum or platinum).
[0003] In the production process of the single crystal furnace, the conductive slip ring will move frequently and bear a large pressure and impact. The conductive slip ring enables the current in the single crystal furnace to flow smoothly, thereby controlling the temperature and heat distribution in the single crystal furnace. The slip ring plays a role of transition of the servo motor transmission line. The quality and durability of the electric slip ring are crucial to the overall performance of the single crystal furnace. When the pull head rotates, if there is no slip ring transition, the servo motor transmission line will rotate together with the pull head, which will cause the transmission line to be wound and broken. The prior art usually adopts a DC motor, and therefore only one slip ring is needed because the DC motor has strong anti-interference ability. However, if one slip ring is used to transfer current and signal, the signals between the fast and slow speed motors are easy to interfere with each other, which will cause the measurement of the encoder to be disturbed, and it is difficult to ensure the normal operation of the single crystal furnace.
[0004] Therefore, when one slip ring is used for transfer, the problem of mutual interference of fast and slow signals will occur. CONTENT OF THE UTILITY MODEL
