Research On Core Equipment For Recycling High-tech Value Chips From Waste PCB

With the advent of more and more new electronic products,the number of electronic products eliminated by people is increasing rapidly.On the one hand,the domestic waste electronic is growing rapidly,on the other hand,a large number of foreign waste electronic garbage has been recovered,which has become a major risk of environmental safety in China.The problem of recycling waste electronic products has gradually attracted people ’ s attention,and the treatment of waste circuit boards is a key problem.Waste circuit boards contain a large number of rare metals and precious metals.If it is ignored,it will waste a lot of useful resources.If it is not properly located,it will also cause adverse effects on environmental safety.Therefore,in order to effectively collect and utilize valuable materials,high-value electronic components on waste printed circuit boards can be removed and recycled.Intelligent identification of high-value electronic components and targeted recycling can effectively reduce processing costs,improve recycling efficiency and reduce environmental pollution.By analyzing the design and research of recycling technology of waste PCB components at home and abroad,and combining with the actual design and assembly requirements,this paper designs a cutting and recycling equipment for chips on waste PCB boards,which can effectively improve the recycling efficiency and safety of high-value chips on waste PCB boards.The main research work includes :1.Through demand research,the existing secondary recovery methods of waste chips are studied and compared,the advantages and disadvantages are measured,and the work target demand is analyzed to determine the overall recovery process.2.Modular design of each station,matching and coordination of position relationship,transmission coordination and size positioning3.between modules.4.Using PRO/E software for model design and assembly,drawing part drawings,determining part size details,analyzing the feasibility of the program.Calculation of driving device and cylinder selection parameters to determine the appropriate model.Test the performance of related sensors to verify the reliability of the machine.5.Solution design of pneumatic system and PLC control system.The design requirements of the pneumatic system are analyzed,the driving load of the cylinder is calculated,and the appropriate pneumatic components are selected.The schematic diagram of the gas path operation principle of the system is drawn,and the design of the gas path system is finally completed.The basic structure of waste PCB high value chip recycling system is analyzed,the reasonable and efficient control logic steps are designed,and the appropriate PLC and other components are selected to complete the design of the control system.5.In order to further improve the safety and reliability of the hardware operation of the waste PCB high-tech value chip recovery equipment,the abnormal operation of the equipment hardware is analyzed and debugged in time after the completion of the machine assembly work.The common finite element analysis software such as ANSYS Workbench is used to simulate and optimize the structure scheme,and the structure scheme is optimized.The motion simulation of the blade cutting circuit board part is carried out to test the cutting effect.Referring to the results of finite element analysis,it is helpful to reduce the conflict between structures in equipment movement and optimize the structure and operation scheme.
