Design And Analysis Of Automatic Insert Machine Control System

Automatic plug-in machine,is a PCB through-hole fast plug-in equipment.With the technological innovation of the precision electronics industry,the processing and production of electronic components tend to be micro-dense and diversified.In order to solve the problem of electronic components assembly technology upgrading in small enterprises,it is necessary to develop an automatic plug-in device which can meet the needs of the market.With the motion control system of the automatic plug-in machine as the theme,the following design and analysis are carried out:Firstly,the hardware frame of the control system of the plug-in machine is set up with the GTN operation control card as the main control unit,and the whole scheme of the operation control system is designed.The hardware includes PCB delivery system,feed system,plug-in system,vacuum pneumatic module.The modular design of each mechanism can effectively enhance the whole device's plug-in beat.Secondly,by establishing the driving model of the Z-axis plug-in head,the angular displacement controller of the plug-in head load and external interference is designed and simulated in Matlab.The result verifies the accuracy of the plug-in head operation control system.Thirdly,on the basis of the hardware platform of the automatic plug-in machine,the motion control program of each module is compiled with the base library function of the GTN operation control card.The object of the software drive control includes the X/Y/Z servo control shaft I/O module control shaft W/V,and the vacuum pneumatic part.In addition,the software programming involves the operation detection of the automatic plug-in equipment,alarm system,and the design of the upper computer debugging interface.After debugging and running the plug-in machine,it is found that the assembly of the plug-in can be preliminarily completed.
