Abstract
|
The placement machine is the largest electronic manufacturing equipment that plays an important role in the highest-tech content, the production capacity and efficiency of assembling in the production line. It is a complex optical, mechanical, electrical and gas integrated system. Its core technology and products are monopolized by the foreign .That greatly restricted the electronic manufacturing of china.The research topic takes Solectron Corporation QUAD QSP-2 SMT as an object of study. The writer replaced the original IPC, motorial card and stepper motor drivers on the basis of retaining the original mechanical struction.What is more, the writer improved and optimized the Z-T axis, X-Y axis and pneumatic part accomplished by the previous staff, while the writer has been tried and dicussed for PCB, feeding mechanism and the visual system. Ultimately the writer has completed a whole patch process through continuous experimentation.The research work is divied into three parts mainly. Firstly, the writer has designed the hardware system of the surface placement machine, including the pneumatic system, the control of X-Y axis and Z-T axis, the deferent organization of PCB board, the mechanism of feeding and nozzle change. Secondly, the writer has studied the hardware of visual system and the methods of control, involving the select of light source, the designation of imaging system, the select of CCD and image capture card. Tirdly, the pitch datas were imported into the control system.Subsequently, the writer has researched the coordinated control methods of the various modules.
