Chapter 3 - Robot Installation 3.5 Mounting Frame Overview The Adept Quattro s650H robot is designed to be mounted above the work area suspended on a user-supplied frame. The frame must be adequately stiff to hold the robot rigidly in place while the robot platform moves around the workspace. While Adept does not offer robot frames for purchase, and the frame design is the responsibility of the user, we provide here some general guidelines as a service to our users. Adept makes no representation or warranty with respect to these guidelines, or the rigidity and longevity of the structure designed and built by the user or for the user by a third party using these guidelines. In addition, when the robot is mounted on the structure based on these guidelines, Adept does not guarantee that the robot will perform to the specifications given in this product documentation, due to user’s frame or user’s production environmental factors. As an example, a sample frame design is presented and discussed. For generalized application performance, frames built to the specifications of this sample should experience no degradation in robot performance due to frame motions. Applications requiring higher than 6 kg * 10 g forces across the belt and/or 6 kg * 3 g along the belt may require a stiffer frame design.

Mounting Frame NOTE: More specifications for the sample frame are provided in Section 7.6. Any robot’s ability to settle to a fixed point in space is governed by the forces, masses, and accelerations of the robot. Since “every action has an equal and opposite reaction”, these forces are transmitted to the robot frame and cause the frame and base of the robot to move and possibly vibrate in space. As the robot system works to position the tool flange relative to the base of the robot, any frame or base motion will be “unobservable” to the robot system, and will be transmitted to the tool flange. This transmitted base motion will result in inertial movement of the tool flange mass, and will cause disturbance forces to be introduced into the robot control system. These disturbance forces cause “work” to be done by the robot servo control system which may result in longer settling times for robot operations. It is important to note that, even after the system reports the robot to be fully settled, the tool flange will still be moving by any amount of motion that the suspended base of the robot may be experiencing. Frame Orientation The sample robot frame design is stiffer in one direction than the other. This is to accommodate conveyor belt applications where the robot is moving with much more acceleration across a conveyor belt than along it. The conveyor should generally be aligned so that the belt travel is along the robot World Y-axis, and the mid-height frame members cross the belt at a 90° angle. The across-the-belt dimension of the frame should be minimized to get the best performance of the robot in that direction. While this frame design assumes a 1.8 m across-the-belt frame dimension, a 1.5 m dimension would offer increased stiffness and possibly increased robot performance at high accelerations and payloads. The mid-height horizontal members are important to the frame stiffness, and should be located as close to the belt as possible. For applications requiring high accelerations along the direction of belt travel, consideration should be given to strengthening the frame in that direction. Frame Construction Typically, the frame is constructed of welded steel members. Hygiene-sensitive applications may call for stainless steel fabrication, with care taken to seal up all possible voids and grind smooth all weld joints. For other applications, it may be suitable to manufacture the frame of carbon steel and paint the resulting assembly. The frame design presented here is based on a stainless steel construction using 10 mm thick members. It may be reasonable to use a reduced thickness for carbon steel assemblies. Some customers may choose to use tubular members, or turn horizontal members at 45° angles to facilitate water runoff from the flat frame surfaces. Robot-to-Frame Considerations The Quattro has a moderately-complex mounting requirement due to the nature of the parallel-arm kinematics and the need to minimize the robot size and mass. Figure 7-5 on page 86 shows the inner arm travel and how it may encroach on the robot mounting points. The design suggested here uses transition pieces to allow for butt welds and mating interfaces where there will be no protruding surfaces to collect contamination. This mounting design results in a natural frequency of about 90 Hz for just the robot Adept Quattro s650H Robot User’s Guide, Rev A 39
