This paper describes a machine designed to process small PVC pieces, used in automobile cable testing equipment. This machine should allow several different processing tasks without too much reconfiguration, thus providing a high level of automation. The solution is based on a three axis movable platform moving inside a cage structure where several tools are attached. This paper describes the machine control hardware and software, not the mechanical structure. The machine processes a piece at a time. The piece is placed in the platform and held in place by a gripper. The platform moves inside the cage placing the piece in the appropriate tool position, following a checklist of operations. The machine is controlled by a PC (Personal Computer), equipped with a commercial I/O interface board and a motion control board. The software developed is composed of three modules for the different control and configuration needs. One used after the machine is physically reconfigured. The second module allows the definition of the operations to be performed and respective coordinates. This module is used when a new series of pieces is to be processed. The third module controls the manufacturing process.
The industry high quality requirements stimulate the development and spread of automatic systems that allow flexibility and easy adaptation to new tasks and needs. The system explained in this paper is built to allow a quick and easy way to process small quantities of small pieces made of PVC substance. The system, made up of several components, brings a high level of automation as required by the company that will use it. To implement this machine, based on a movable platform, National Instruments I/O boards and the LabView 6i software tool have been used. This paper describes, in a general way, a system that allows a high variety of applications but, for the moment, is applied only to process little lots of PVC parts.
This paper describes a machine designed to process little quantities of small PVC pieces, used in automobile test equipment. The system should provide a easy way of reconfiguring to process all the pieces used, as they are very much alike, but with significant differences. The machine this paper proposes is based in a 3 axes moving platform controlled by a PC equipped with commercial I/O boards. The next sections will explain the different modules that constitute the above-mentioned system.
