EXPERIENCE:

Graduate Assistant at PLC and RISC lab at University of Bridgeport From: January 2011 to present

• Robotic Arm integrated with conveyer line, cognex vision sensors, Proximity Sensors and Air Cylinders

The goal of this project is the construction of a robotic system that performs pick & place of an object as well as sorting of the metal & nonmetal object. It also comprises of integration of Programmable logic controller, Electro – Pneumatic cylinder system, HMI, Sensors and Cognex Vision System. This station is controlled by PLC as master unit and Robotic Arm as Slave which perform different action.

The station operates in two modes of operation

Mode 1-Full Automation mode.

Mode 2-Semi Automation mode.

Mode -1 :Object is detected by load area sensor at in-feed area. Then Cognex Vision Camera decides whether it is good or bad part & sends command to robot to perform it's task after decision. Accordingly, robot places bad part at rejection area and good part in feed conveyor.

Mode -2: Robotic Arm will Only Help in Displacing Non-Metallic object or Pass the Metallic Object through the Conveyor Belt. But object should be placed manually in feed conveyor. Can only differentiate metal and non metal parts.

• Closed loop communication and networking using VFD, PLC and Ethernet

Using Allen Bradley SLC 5/03 PLC, Cutler Hammer Panelmate HMI [B] Using AB Compact Logix PLC (RSLogix5000) and AB Panel view plus 600 HMI. Application of VFD is used to control the speed of 3-phase induction motor by changing the frequency of AC. Speed of the motor is controlled in three different speeds i.e. slow, medium and fast. This designed station can be operated by both push buttons and HMI individually. To be familiar with load cell sensor application, load cell is applied to control motor. We defined certain gram of weight, when load cell sense and exceeds the defined weight it will send signal to PLC to stop motor. Panel can be operated on the Ethernet (LAN) network through HMI from remote area.

• Control Panel Design - Quality Control Machine (Academic Master’s Project): Concept of this project is to determine whether part is good or bad with the integration of PLC(Mitsubishi FX3U series), ERC2 -IAI Actuator, Cognex Vision Camera(3G1 Checker). Different preset position are defined at IAI Actuator like loading position, reject position, accept position and different positions under cognex according to the different jobs loaded to checker. Object is determined good or bad once it is run through cognex positions. If it is good it will go to accept position else to reject position. We are using gripper to grab object, one eye sensor to determine presence of object and two air cylinders at accept and reject position to push the object. When object is pushed either at accept or reject position it will go back to loading position for another object. We are operating this project with HMI program E-Designer with HMI screen model E-1041.
