Abstract

This paper presented the development of the assembly station – Back Cover Assembly Station in the Computer Integrated Manufacturing (CIM) systems of assembling the LCD monitor back cover. CIM can be define as the integration of all the processes necessary to manufacture a product through the use of computer technology, tool or method used to improve entirely design, manufacturing process and increase productivity. The outcome idea for this CIM system is an open modular conveyor system with a centralized control unit (OMRON PLC) employing the control methodologies and integration tools. The system is build in used for controls of an automatic product feeder station, a conveyor transfer module, three automatic assembly stations and a vision module which all these stations will be arranged along the conveyor. The assembly process for this assembly station is it starting with the feeder module which it will feed away a piece of LCD monitor back cover to preset location, waiting for the suction system to pick up and transfer it on to the conveyor line and replace it over the half-assemble LCD monitor. The suction system was attached together with the z-axis transfer module as it moves up and downwards together for lifting and placing process (know as pick and paste process). After that, a cylinder will activate to apply force to the surface of back cover, in order to snap fit the back cover with the half-assemble LCD monitor. In this thesis too, a draft PLC program for the station has been purposed, the program has been tested with OMRON Light Training Kit and it does prove it work correctly. The program usage is to be a reference for future studies and development. Finally, it can conclude that this project has fulfills the course outline of Manufacturing engineering, which majoring in the field of Automation. This project involves not only automation skills, but also design, manufacturing and mechanical skills.
