Combined clamp for cutting off monocrystalline silicon bar stock

一种用于切断单晶硅棒料的组合夹具

Abstract

本实用新型涉及一种用于切断单晶硅棒料的组合夹具,设置在带锯切割机工作台上,其特征在于:它由分别位于带锯两侧的夹卡装置和扶正装置组成,所述夹卡装置由导轨、滑块和三组并列的夹紧机构组成,其中导轨与工作台托板固定,滑块与导轨滑动连接,夹紧机构位于滑块上,所述扶正装置由两组并列的扶正机构组成。本实用新型针对单晶硅棒料切断过程不易夹卡定位而影响质量问题设计了一种组合夹具,该组合夹具在带锯两侧对单晶硅棒料分别夹紧、扶正,解决了原夹具因固定方式不妥而造成的切割端面掰断裂痕及垂直度误差问题。采用本实用新型在有效降低单晶硅棒料切割不合格率、提高单晶硅使用率的同时,还提高生产率、降低人工操作强度。
The utility model relates to a combined clamp for cutting off a monocrystalline silicon bar stock, which is arranged on a work table of a band saw cutting machine. The combined clamp is characterized by consisting of a clamping and locking device and a righting device which are respectively arranged at two sides of a band saw; the clamping and locking device consists of a guide way, a slide block and three sets of parallel clamp mechanisms, wherein the guide way is fixed with a support plate of the work table, the slide block is in slicing connection with the guide way, and the clamp mechanisms are arranged on the slide block; and the righting device consists of two sets of parallel righting mechanisms. Aiming at the problem that the quality is influenced since the monocrystalline silicon bar stock is hard to clamp, lock and position when the monocrystalline silicon bar stock is cut off, the combined clamp respectively clamps and rights the monocrystalline silicon bar stock at two sides of the band saw, thereby solving the problems that a cutting end face is broken to have a crack and the perpendicularity error since the existing clamp is bad in fixing mode. With the combined clamp, the reject ratio for cutting the monocrystalline silicon bar stock is effectively reduced, the utilization ratio of the monocrystalline silicon is effectively improved, the productivity is improved, and the manual operation difficulty is reduced.
