Whatever your assembly needs might be, Yaskawa Motoman has proven robots, applications expertise, solution partners and a global support network that can put it all together for you.

 

Assembly Operations

Assembly applications typically consist of multiple operations. While the operations vary with the application, we’ve listed several of the most common operations below.

part_location.jpgPart Location

Presenting parts to robots varies widely from application to application. In the past parts needed to be precisely fixtured so that the part is always in the same position and orientation. This is expensive, time consuming and doesn’t allow for flexibility when the part type or size changes.

Our MotoSight™ vision products can help locate the parts so that the robot can pick them up precisely and consistently. This includes parts that are loosely fixtured, parts that are presented on a conveyor and in some cases parts in a box or bin.

partID.jpgPart Identification

Traceability and genealogy of parts is crucial to many manufacturing or production processes. Other processes simply require parts to be identified for a specific operation such as assembly or kitting. Our MotoSight products can help identify and validate parts based on part geometry (shape and size), color, barcode, markings and other features.

Part Sortation

Many manufacturing and production processes require part to be sorted. Our MotoSight vision products can help select and sort parts based on part geometry (shape and size), color, barcode, markings and other features.

Flexible Feeding

Flexible feeding is an innovative way to present parts to a robot. Parts are fed out of a bulk hopper and onto a feed surface. A feed surface may be a solid indexing or vibratory surface of a conveyor belt. A camera mounted above the feed surface locates the part and determines its orientation. The robot then picks the parts and performs the necessary operation. If the part size or type changes, you need only make minor changes to the vision locator tool and perhaps the gripper fingers. Flexible feeding is ideal for production processes requiring multiple part types or a family of parts. Our MotoSight products are ideal for flexible parts feeding.

Bowl Feeding

Typically uses a vibratory motion to advance parts from a bulk hopper. Parts are advanced from the hopper onto a rail (or into a groove) that orients the part and presents it to the robot. Bowl feeders are typically designed and built based on the part geometry and mass. Bowl feeders are well suited for applications where the part shape or size does not change. Bowl feeders are not recommended for applications where the part is expected to change.

Conveyance

Conveyance is used throughout manufacturing processes to move parts from place to place. This includes continuous belt conveyors, indexing belt conveyors and indexing pallet conveyors. Our robotic assembly systems can work with all conveyance methods.

End-Effectorsadpative-gripper.jpg

End-effectors (or end-of-arm-tooling) are how the robot grips the parts. Complex and advanced assembly operations require the robot to accurately and precisely locate and grip the parts. Often a base actuator (often pneumatic and sometimes electric) is used to perform the open and close motion. Custom gripper fingers are attached to the actuator to ensure proper gripping of the parts. When a variety of part types and sizes are used, end-effectors can become complex.

Some operations necessitate compliance built into the end-effector. This can be done at the gripper fingers or where the end-effector attaches to the robot.

Tool Changing

Tool changing is often required for automated assembly operations. As different part types and sizes are needed, multiple gripper configurations might be required. Tool changers provide the flexibility to automatically change end-effectors or other peripheral tooling.

Adaptive grippers are capable of grasping multiple part types and sizes and can be used in some robotic assembly applications.

Force SensingSDA5D-670395-edited.jpg

Force sensing is often needed for insertion or tightening operations. A force sensor provides feedback to the robot control system and can measure forces and toques being applied at the end-effector. The feedback loop is closed very quickly (typically at 1 ms) so that the robot can pause when a desired force is achieved or alter the direction of the robot. This is especially useful when assembling a complex mechanism that involves meshing gears.

Part Fastening or Joining

Part fastening/joining is a critical part of many assembly operations. After all, the nature of assembly is bringing multiple parts together. The fastening and joining methods can vary greatly and depend upon the part types being assembled. Typical fastening methods include screwdriving, dispensing glues and adhesives, ultrasonic welding and inserting clips.

present-absent.jpgPresence / Absence

Operations often require validating if a part or a feature on a part is present or absent.  If the part/feature is present the operation continues. If the part/feature is absent, the exception can be caught and managed. Our MotoSight products can help determine presence of a part or feature based on geometry (shape and size), color, markings and other features.

Error Proofing

Error proofing is similar to Presence / Absence.  Preventing a manufacturing error before it occurs or detecting an error early in the process can save companies from shipping faulty or defective product. Detecting holes present, threads on a bolt, caps on a bottle, part in a fixture, and whether or not a part is oriented correctly are all examples of error proofing. Our MotoSight products can be applied to error proofing in virtually any application.

inspection.jpgVisual Inspection

Shipping faulty or defective products can be devastating to a business. Machine vision has a long history in part inspection, ensuring consistent and predictable quality. Whether it’s gauging a part, detecting presence of a feature or error proofing, our MotoSight products have all the necessary inspection and data analysis tools for part inspection.
