根据废旧线路板的特点,设计了一款高效节能的拆解装置。该装置先利用高温高速气体分别对废旧线路板两面进行加热解焊,再利用螺旋辊刀对废旧线路板上的插装元件和表面贴装元件进行拆卸。以插装元件的损伤最小为优化目标,对双螺旋辊刀的结构参数进行优化计算。研究结果表明:当辊刀直径为30 mm,螺旋角为26o,刀刃压力角为0o,螺旋线数为4时,废旧线路板插装元件的拆解效果最好。为废旧线路板的高效、绿色回收处理提供新的方法和技术。

According to the characteristics of waste PCB (Printed Circuit Board), an energy-efficient disassembly device was designed in this paper. PCB was heated by high temperature and high speed gas. And then the THD (Through Hole Device) and SMD (Surface Mount Devices) on PCB were removed by spiral hob. The cutter parameters were optimized for the optimization goal the minimum damage of THD. The research results showed that: When the diameter of the knife roller is 30 mm, the helix angle is 26°, the blade pressure angle of 0°, spiral line number is...
