This configuration minimizes the effects of gravity on the robot by downloading them to the ground and allowing the use of this machine in cases of strong pressures as in vertical perforations. In a SCARA robot junctions of the shoulder and elbow are vertical and the wrist moves vertically. The mechanics of the SCARA arm is generally quite strong and can withstand without problems unexpected stress and collisions. SCARA kinematics makes this robot particularly suitable to perform assembly tasks with tight tolerances, such as putting a shaft into a hole, thanks to the capability to adjust the movement on the horizontal plane, while at the same time maintaining high rigidity on the vertical direction.

Morover these robots are used in the automotive field, as well as electronic, and other industrial fields where manufacturers needs to feed bulk components of all sizes in these areas FlexiBowl® is performing so good that is replacing others parts feeders. This is why it is often used with FlexiBowl®. This type of robot has been developed to improve the speed and repeatability ON PICK&PLACE TASKS from one location to another or to speed and improve the steps involved in assembly. The SCARA robot is a manipulator with four degrees of freedom. FlexiBowl® is capable of feeding entire families of parts and does not require any retooling cost for product changeovers: product changes can be made in a matter of seconds without any trouble. Once bulk components lie on feeder surface with the right orientation, the vision system can locate them and send coordinates to the robot for pick up. Thanks to FlexiBowl®, the innovative parts feeder that doesn’t work with vibration, but through the combined actuation of servomotor and impulse generator, assembling can be very flexible. Some SCARA characteristics like high reliability, high accuracy and speed, minimum maintenance, ease of use and extremely compact design make this kind of robot really suitable to work with FlexiBowl® the composed system guarantees high performances in term of productivity and, at the same time, high flexibility in assembly lines and production systems. Scara Robot Characteristics: reliability, accuracy, speed. These are the most popular geometries for vertical assembly and small parts pick-and-place operations. An alternative configuration has the linear Z motion as the second axis. Scara Robots configurationįour axis SCARA robot that consists of an inner link that rotates about the World Z-axis, connected to an outer link that rotates about a Z elbow joint, which in turn is connected to a wrist axis that moves up and down and also rotates about Z. Additionally, robots can be quickly reprogrammed to reflect changes in production needs and cycles. As such, robots provides consistent reliable performance, repetitive accuracy and are able to handle heavy work loads and perform in harsh environments. Industrial robots are defined as ‘multi-functional manipulators designed to move parts through various programmed motions’. Generally a SCARA robot can operate at higher speed and with optional cleanroom specification. The SCARA robot is most commonly used for pick-and-place or assembly operations where high speed and high accuracy is required. The SCARA acronym stands for Selective Compliance Assembly Robot Arm or Selective Compliance Articulated Robot Arm.
