ROBOTICS OPERATIONS

Processing Operations:
– Robot performs a processing procedure on the part.
– The robot is equipped with some type of process tooling as its end
effector.
– Manipulates the tooling relative to the working part during the cycle.
– Industrial robot applications in the processing operations include:
•
Spot welding
Processing Operations
• Continuous arc welding
• Spray painting
• Metal cutting and deburring operations
• Various machining operations like drilling, grinding, laser and waterjet cutting,
and riveting.
• Rotating and spindle operations
• Adhesives and sealant dispensingAssembly Operations:
– The applications involve both material-handling and the manipulation of
a tool.
– They typically include components to build the product and to perform
material handling operations.
– Are traditionally labor-intensive activities in industry and are highly
repetitive and boring. Hence are logical candidates for robotic
applications.
Assembly Operations
– These are classified as:
• Batch assembly: As many as one million products might be assembled. The
assembly operation has long production runs.
• Low-volume: In this a sample run of ten thousand or less products might be
made.
– The assembly robot cell should be a modular cell.
– One of the well suited area for robotics assembly is the insertion of odd
electronic components.

– Some inspection operation require parts to be manipulated, and other
applications require that an inspection tool be manipulated.
– Inspection work requires high precision and patience, and human
judgment is often needed to determine whether a product is within
quality specifications or not.
– Inspection tasks that are performed by industrial robots can usually be
divided into the following three techniques:
Inspection Operations
• By using a feeler gauge or a linear displacement transducer known as a linear
variable differential transformer(LVDT), the part being measured will come in
physical contact with the instrument or by means of air pressure, which will
cause it to ride above the surface being measured.
• By utilizing robotic vision, matrix video cameras are used to obtain an image
of the area of interest, which is digitized and compared to a similar image
with specified tolerance.
• By involving the use of optics and light, usually a laser or infrared source is
used to illustrate the area of interest.
