DESIGN AND CONSTRUCTION OF AUTOMATIC COIL WINDING MACHINE

CHAPTER ONE

INTRODUCTION

Typically, a winding machine winds a material such as metal wire, thread, or paper, onto a core, spool, or bobbin. There are several different types of winding machines, from simple manual feed machines to complex computer-numeric-control (CNC) machines. Some of the more common uses for winding machines are coil winding, rope winding, and continuous filament winding. Many industries use these devices, including textile, electronics, and wire industries. A manual winding machine usually has a core on a spindle and the user feeds wire, rope, or other material onto the core. The user controls the spindle speed and feeds the material through user hand, guiding it to control the tension and load pattern. These simple machines may be of a bench-top size or large stand-alone winder.

A coil winding machine is a machine for winding coil onto a spool, bobbin and many more. This coil winding machine is one of types of winding machine that available in industries today. The coil winders can be classified according to their speed levels and capacity. From multi speeded machines to medium, large and extra-large machines, these machines come in various types and categories, performing a range function. The common applications for a coil winding machine are to wind coils for transformer, inductors, motor and chokes. Coil winding machine design is dictated by a coil’s complexity, material tension limitations, machine versatilities, and automation / operator intervention, production volume and budgetary considerations [3]. Complete types of winding machine ideal for educational institutes, small and medium enterprise.

1.2 Problem Statement

To complete a coil using manual coil winding machine will be inconvenience and waste of time. Furthermore, to have a good quality of automatic coil winding machine requires expensive tools and not user-friendly. Therefore, fabrication of coil winding machine will be done in this project which is controlled by two stepper motor using Arduino . This machine is inexpensive, easy to operate and build in a small-scale size. This project also can be used for training students in winding of small transformers & relay coils.

1.3 Objectives of the project

Basically these projects are listing three main objectives. The objectives are a guideline in order to complete this project. This project is conducted to achieve the following objectives:

To design and build a coil winding machine that has a small-scale and at a lower cost.
To create a program that control stepper motor movement by using Arduino. iii. To be a learning tool for student to wind a small solenoid and transformer.

1.4 Scope of Project

Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, tasks, costs and deadlines. In this project, the scope of the project is including a design and fabrication a small-scale coil winding machine at a lower cost. In this project, the coil winding machine size will be only in desktop size. All the programming and coding project will be using Arduino program to control two stepper motor motion. Some of the coils winding machine components are available at the faculty laboratory such as stepper motor, aluminium plate, and lead screw. Certain component such as round bobbin, guide pulley and motor coupling is fabricated using rapid prototyping machine.
