To reduce labor costs and to ensure consistent quality control of the process,
robotics has been familiar in industry to replace humans in demanding and repetitive tasks.
In factory automation and industrial manufacturing, abstract material handling and pick
and place mechanism are widely used methods and based on applications, different motor
technologies have been designed and employed. High speed and reliability and low robot
gripper costs are necessary for a worthwhile pick and place process. For positioning and
orientation of objects, robotic manipulation is essential as gripper helps in gripping,
sucking, lifting, placing and releasing. Therefore, design and fabrication of suction cup and
pneumatic mechanism is a promising approach for pick and place material with flat surface.
However, current grippers are not able to handle products properly because they have
uneven shapes, are flexible and irregular, have different textures and are very penetrating
to damage. The main aim of work is to design the gripper mechanism and vacuum suction
mechanism working in single and multiple pick and place operations. In this research work,
both designed and development of pneumatic gripper has been done using 3D printing
technology and the vacuum mechanism is created by means of vacuum pump, pipe and
control valve. Experiments validate that the designed gripper was highly effective in terms
of accurate picking and placing and shows encouraging results include effective picking in
smooth as well as rough surfaces. Further pneumatic grippers of varied thicknesses were
compared with conventional suction cups for evaluating overall effectiveness and
efficiency of the designed gripper. The force for the gripper and working of the vacuum
suction are checked and observed for loads at various pressures. |
