一种二极管无氧铜引线打头机用送线装置
摘要：
本发明公开了一种二极管无氧铜引线打头机用送线装置，它包括送线器、送线滚轮、驱动机构以及压紧机构；压紧机构设置两组；两组压紧机构分别设置在引线上下两侧，两组压紧机构对引线的压紧方向相反；压紧机构包括设置在引线上方的主轴、偏心套、支撑环以及球形支撑；主轴上设置偏心套；偏心套上设置四组支撑环；四组支撑环顶端分别装有一组球形支撑；支撑环与引线之间通过球形支撑接触；主轴带动偏心套旋转时，球形支撑做正弦提升运动；两组压紧机构之间的直线距离为主轴长度的整数倍。本发明的送线装置根据无氧铜的引线特性设置，在压紧机构处通过正弦提升运动扭曲引线使得送出的引线处于压紧状态，扭曲后复位在压紧的同时减少对引线的拉伸力。
摘要（英）：

The invention discloses a line feeding device for a diode oxygen-free copper lead heading machine. The line feeding device comprises a line feeder, a line feeding roller, a driving mechanism and two groups of press mechanisms, wherein the two groups of press mechanisms are respectively arranged at an upper side and a lower side of a lead, press directions of the two groups of press mechanisms areopposite, each press mechanism comprises a main shaft, an eccentric sleeve, support rings and spherical supports, the main shaft is arranged above the lead, the eccentric sleeve is arranged on the main shaft, four groups of support rings are arranged on the eccentric sleeve, a group of spherical supports are arranged at top ends of the four groups of support rings, the support rings and the lead are in contact by the spherical supports, the spherical supports do sine lifting motion when the eccentric sleeve is driven to rotate by the main shaft, and the linear distance between the two groups of press mechanisms is integral multiple of the length of the main shaft. By the line feeding device, the lead is twisted by the sine lifting motion at the press mechanisms so that the sent lead is ina press state according to the characteristic of the oxygen-free copper lead, the stretching force on the lead is reduced when the line is reset and pressed after twisting.
