Design of Electro Magnetic Gripper

We would like to take opportunity to express our humble gratitude to Mr..

Denis shook S under whom we executed this project. His constant guidance and willingness to share his vast knowledge made us understand this project and its manifestations in great depths and helped us to complete the assigned tasks. And also we would like to thank Mr.. Panhandled C who gave this opportunity for us. An arrangement for gripping metallic work pieces formed of ferromagnetic materials or electrically conductive materials, by means of electromagnetic forces.

The electromagnetic Interaction with the part Is the key Issue In the electromagnetic gripping and this project helps In the realization of concept of automation In an Iron foundry. It is an assembly formed of a housing having an electromagnetic coil armature reciprocally mounted . The industrial robots are one of the most important devices for better, modern and safer automation. Requirements of today's manufacturing industries are very high. To meet the requirements of the market many companies decide to use industrial robots for better and cheaper products.

The industrial robots can perform work in many areas of the industry e. G. Pick and place objects, assembly, welding, painting and many more. There are several advantages of using industrial robots In manufacturing. Some of the benefits are: ;Since the robots are flexible and possible to reprogram, Increases the possibility of changing In the production. ;The working environment for the man becomes better and easier, because the robot can carry heavy and do dangerous work.

;More efficient production for a lower cost. The robots can repeat the same work in exactly the same way, therefore the quality of the production increases.The robots who work in a certain area must have a suitable gripper for the work. There are many types of grippers. The most common grippers are Jaw-type, vacuum and magnetic grippers.

The selection of the gripper is very important as the gripper is the device between the robot and the work piece. There are many deferent grippers and several types of gripping techniques. The gripper In this thesis will pick and place deferent notched metal whets. The parts have different shapes and therefore different weight.

The working procedure mainly comprises of : 2. Grip 3.Transport 4. Release The electromagnetic gripper comprises of 'n' grippers depending upon the work load and are internally wounded with copper coil connected to a robotic arm, which can control the power variations. So, that when the lifting operation starts the power is supplied to the grippers then the electrical energy is converted to magnetic energy in the grippers due to the armature winding inside the gripper and due to the magnetic energy it attracts the Job and hold firmly until the Job is transferred to the specific place. The main criteria in the procedure is gripping of the Job.

Let includes four electromagnets. There are two large and two small magnets. The electromagnets in middle of the gripper are the smaller ones and the magnets which sits at the far end are the larger ones 2. At includes eight electromagnets. There are six large and two small magnets.

The electromagnets in the middle of the tool are the smaller ones and the electromagnets which sit at the far end and on the wings are the larger ones 3. At includes eight electromagnets. There are four large and four small magnets.The electromagnets in middle of the concept are the smaller ones and the electromagnets which sit at the far end are the larger ones. 4.

At includes four electromagnets. The magnets in this concept are operated like the magnets in type 1 . This concept doesn't need battery backup for the electromagnets. The procedure of gripping started in the late ass's with a strong electro magnet to lift the goods from he port to the cruise and now the application is used in many fields like manufacturing , recycling surgical operations . Although it has many wide applications it is mainly used for lifting and transporting operations where gripping arrant accent. PARTS REQUIRED: 1.

Grippers. 2. Copper coils. 3.

Robotic arm. 4. Power supply. 5. Nuts and Bolts.

6. Housing. Theoretically study of different lifting and gripping techniques. To be able to design a gripper tool for an industrial robot, different lifting and gripping techniques must be studied. Information about different gripping and lifting censuses will be known for deciding which gripping or lifting technique will fit the design of the gripper tool in this thesis. Selection of lifting and gripping technique.

When the information about the different gripping and lifting techniques are known, one of those techniques are being selected as lifting or gripping technique. ;Design of several concepts. With help of the gripping or lifting technique, several designs of different concepts will be made in Solid works. The concepts will be designed with consideration to the industrial robot and the criteria of the gripper tool.

Evaluation and comparison of concepts when the different concepts are designed an evaluation and comparison of the concepts will be made.Some functions of the concepts will be compared to each other, the different functions will be given points from 1-10 where 10 is the high stand 1 is the lowest. The concept that receives most points and meets the requirements in the best way will be selected for a final design. ;Development and a final design of selected concept.

The development and a final design of the gripper tool will be made in Solid Works. Assembly and detail drawings will be made n Solid Works. ;Experiment in ABA Robot Studio.A robot cell system will be built in ABA Robot Studio, where the gripper tool will be mounted on an industrial robot. Transportation of the different parts to different stations will be simulated at this experiment.

Iron ore industries. * Recycling of scrap in industries. * Used in surgical operations. * Any lifting operations. * Separation of thin, porous work pieces * Support for vacuum gripping systems in applications involving highly dynamic handling of sheet metal parts. * Handling of rough metal sheets, perforated sheets ND sheet metal parts with holes or complex shapes.
