Description
Technical field
The present invention relates to a kind of the waste and old circuit board components and parts be carried out the automation equipment of industrialization overall pulling down, relate in particular to a kind of based on reuse of component, the harmless equipment of removing of globality.
Background technology
Wiring board is called for short PCB, be the indispensable part of electric equipment products, along with the develop rapidly of electronics industry and the continuous application of new and high technology, the quantity of waste and old electric electric equipment products sharply increases, produce a large amount of waste and old circuit boards thus, promptly had the wiring board of components and parts.Waste and old circuit board brings immense pressure for society and environment as a kind of electron wastes of enormous amount.Analyze and test to detect and show that the most functions of the components and parts on the waste and old circuit board are used by intact can the continuation; Simultaneously, owing to contain various poisonous and harmful substances and noble metal in the components and parts, component disassembling before carrying out circuit board recycling on it can greatly be simplified subsequent treatment process, especially reduces the complexity and the corresponding environmental protection investments of environment-protective process in the subsequent treatment.And this dismounting must be economical and industrialization, and the single demolition technique based on maintenance far can not satisfy current needs at present.
But carrying out component disassembling one at circuit board is the components and parts that obtain function reuse, the 2nd, simplify subsequent treatment process.Dismounting purpose difference, the method for its dismounting are also different.Existing both at home and abroad at present much at the method for dismounting and the equipment of various components and parts and various purposes, but remove equipment report is not arranged based on circuit board element reuse of component, that can carry out commercial application.
Chinese invention patent CN1590032A, an open day 2005.3.9 have proposed a kind of electronic component method for dismounting, with circuit board clamping heating, shake components and parts with impactor then.Since circuit board material characteristic, most of circuit board soften with heat, and impact effect can descend.Chinese invention patent CN1600458A, open day 2005.3.30 propose a kind of method that splits electronic component and reclaim scolder, are by hot air, remove element and reclaim scolder with mechanical round brush and powerful suction nozzle.Since circuit board can not seal when installing in device well and substrate on the existence of through hole, it is also bad that it removes effect.Chinese invention patent CN101014229A, an open day 2007.8.8 have proposed a kind of component disassembling method and device, the heating of employing hot blast, spacing case splendid attire is fixed or adopted to wiring board, and the cam percussion mechanism is implemented to impact, and the elasticity guipure separates, collects components and parts and scolding tin.Because make the fusing of heat circuit boards solder by hot blast heating, efficiency of utilization is low, energy consumption is big, easily causes the components and parts inequality of being heated.Chinese invention patent CN1897790A, an open day 2007.1.17 propose a kind of printed circuit board component separating technology, be liquid medium to be heated to more than the scolding tin melting temperature by heater, printed circuit board (PCB) is placed on the liquid medium surface, take out printed substrate Deng after the scolding tin fusion, can realize the separation of printed circuit board component.This method adopts artificial loading and unloading, operational hazards, and automaticity is lower.Chinese invention patent CN100496192C, an open day 2009.6.3 have proposed a kind of method and apparatus that printed circuit board (PCB) is immersed separating component in the liquid thermal conductivity media, be that the pending circuit board that will be welded with components and parts is immersed in the liquid thermal conductivity media, keep liquid thermal conductivity media on the temperature of melts soldering tin, treat to collect scolding tin, wiring board and components and parts respectively after the scolding tin fusing.Chinese invention patent CN1935398A, an open day 2007.3.28 propose a kind of circuit board component thermal disassembling equipment and method, are that circuit board is fixed, and again it are heated, impact, and realize component thermal disassembling.More than two kinds of methods also need fixedly clamping, treatment effeciency is more limited.
Above-mentioned prior art has following problem respectively:
1, circuit board is fixed or clamping, and the mode that adopts manual loading and unloading in the operating process, make component disassembling efficient low, be unsuitable for industrialization;
2, the destructive dismounting can't be reused components and parts;
3, as medium heating line plate scolding tin is melted with air, its efficiency of utilization is low, and energy consumption is big; In heating, make components and parts surface and internal temperature thereof all higher, and can cause the components and parts inequality of being heated, fragile, thus influence the utilization again of electronic devices and components;
4, device structure complexity, operating difficulties, non-directional heating in air, poisonous element volatilization or oxidation in meeting accelerating circuit plate or the components and parts as Polychlorinated biphenyls, dibenzofuran etc., cause environmental pollution and operating personnel to poison.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provides a kind of simple, practicality, industrialization, the high and low energy consumption of efficient, of low pollution, it is in the equipment that the waste and old circuit board components and parts can be carried out the industrialization overall pulling down of components and parts function reuse.
Technical solution problem of the present invention adopts following technical scheme:
