The utility model relates to a solar cell chain making herbs into wool field. A roller device of etching groove body, silicon chip (3) that is in in the etching groove body are in between last gyro wheel (2) and bottom roller (1), and the internal portion of etching groove loses the peak that the tank liquor face surpasses bottom roller (1) in vertical orientation minimum is lighter than bottom roller (1), and the gyro wheel surface of bottom roller (1) is a plurality of semi -cylindrical face (5) components of connecting each other. The utility model discloses a bottom roller adopts a plurality of semi -cylindrical faces of connecting each other to constitute the columniform of the one -tenth on the whole gyro wheel surface of bottom roller for elimination gyro wheel seal not only can besatisfied in the bottom roller surface, under the effect of semi -cylindrical face, forms even sculpture layer moreover. 本实用新型涉及太阳能电池链式制绒领域。种刻蚀槽体的滚轮装置，处于刻蚀槽体中的硅片（3）处于上滚轮（2）和下滚轮（1）之间，刻蚀槽体内部蚀槽液面在竖直方向上超过下滚轮（1）的最低点小于下滚轮（1）的最高点，下滚
