Description
Technical field
The invention belongs to electronic waste processing and waste recovery and utilize the field again, be specifically related to a kind of harmless treatment facility and processing method of disassembling thereof of discarded circuit board that be applied to.
Background technology
Printed substrate (Printed Curcuit Board is called for short PCB, or Printed wiring Board, is called for short PWB) is the important component part of electronics and IT products, household electronic products etc.China is world wiring board big producing country, has tens thousand of tons of waste printed circuit boards to produce in the annual production process; Along with the continual renovation of electric equipment products is regenerated, a large amount of electric equipment products are eliminated, and one of its critical component printed substrate is also abandoned thereupon, always takes temperature from discarded circuit board, reaches 7,000 ten thousand tons every year approximately.On the one hand, discarded circuit board is the important source of reclaimed copper, aluminium and multiple noble metal, on the other hand, most of components and parts function on the discarded circuit board is intact, be far from termination service life, can the secondary utilization, thus the resource of from discarded circuit board, carrying out material to reclaim and utilize be following important development direction.Yet,, also will cause huge pressure to society and environment as the unreasonable waste printed circuit board of recovery method owing to contain the part poisonous and harmful substance on the discarded circuit board.Therefore, exploitation is efficient, reliable, the discarded circuit board resource recovery and reuse technology and the equipment of environmental protection, reduce the technical difficulty that each constituent element of discarded circuit board separates, improve separative efficiency, reduced the technical difficulty of separating substances in the printed substrate subsequent treatment, the cost that reduces subsequent treatment has important economic benefit and social benefit.In order to reduce the technical difficulty that each constituent element of discarded circuit board separates, guarantee as far as possible that simultaneously the harmless of components and parts disassemble, before the printed substrate pulverization process, put in order board component and be necessary with separating fast of wiring board PCB substrate.
Chinese invention patent CN1600458A has proposed a kind of from printed circuit board (PCB) partition that is welded with electronic component and the method that reclaims electronic component and scolder.By the blowing mouth of device top the circuit board upper surface blown is higher than the hot-air of scolder fusing point, the solder alloy on the holding circuit plate is in molten condition.Mechanical round brush by being close to pending circuit board lower surface is along the printed circuit board (PCB) reciprocal rolling of moving, and the electronic component of circuit board is swept down and sucked electronics and solder alloy loosening and that be scattered by the powerful suction nozzle on round brush next door by the mechanical force of the bristle on the round brush.By regulating the power of this getter device, make to produce enough big negative pressure at the circuit board lower surface, under the help of mechanical round brush, can pull up electronic component and scolder come from printed circuit board (PCB).Its shortcoming is: can not seal well when installing in device owing to circuit board, add and itself have through holes such as many installing holes, pin jack on its substrate, constantly have under the situation that hot blast is blown at the circuit board upper surface, therefore the circuit board lower surface is not easy to produce bigger negative pressure, for the dismounting poor effect of placing components; By round brush the electronic component of circuit board is swept down, be easy to injure components and parts; Can't continuity disassemble wiring board.
