Robot arm having at least one deformation element
11351679 · 2022-06-07 · ·

A robot arm includes multiple links and joints connecting the links to one another in an articulated manner, wherein, in cooperation with the joints, the links are designed to carry and move a load in space. The joints can be automatically adjusted by motors of the robot arm to move the links. At least one first link has a first casing and a neighboring second link has a second casing. The casings are designed to transfer respective forces and torques resulting from the weight of the robot arm itself and/or the load to the neighboring link. The first casing and/or the second casing has a deformation element designed to form a buffer body in a joint space between the first and second casings, which is changed due to an adjustment of the associated joint. The buffer body at least substantially or completely fills the changeable joint space.

11731290 · 2023-08-22 · ·

A suspension device of suction pads of industrial manipulators is described, which can also be defined as level compensator. The device includes a body and a telescopic stem passing through the body, and sliding between an extended position and a retracted position. A spring constantly applies a thrust on the stem to bring it to the extended position. The device is hollow to allow the suction of the air from the suction pad constrained to the stem. Advantageously the suspension device comprises a brake which can be activated to brake, i.e., slow down, the stroke of the stem or stop it completely.

Robotic tool holder with passive compliance

A compliance mechanism for holding a robotic finishing tool implements passive force control and compliance using one or more double-acting pneumatic pistons. A desired application force is set and maintained by controlling pneumatic pressure in chambers both fore and aft of the one or more double-acting pneumatic pistons. The pressures in the fore and aft chambers are dynamically controlled, e.g., in response to changes in spatial orientation of the robot arm and tool, to maintain a desired compliance force applied by the robotic finishing tool to a workpiece. An external regulator maintains the fore and aft chamber pressures, for a given spatial orientation, throughout the holder's range of compliance motion. The compliance mechanism includes a plurality of piston bores; the number of active pistons may be adjusted for a given operation, e.g., in response to the finishing tool weight.

Pneumatic robotic finishing tool

A pneumatic robotic tool, such as grinder, sander, etc., implements passive force control and compliance using two or more double-acting pneumatic pistons distributed about a pneumatic motor within the tool housing. The multiple pistons facilitate a compact design, reducing tool stack height, as compared to prior-art, single-piston designs. In one embodiment, filtered breather vents and an air pressure equalization passage maintain ambient atmospheric pressure throughout the tool, while preventing the infiltration of dust and other particulates. In one embodiment, a hard port rigidly affixed to the tool housing is provided for at least motor supply pneumatic fluid. The motor supply air is transferred from the hard port to the pneumatic motor via a flexible pneumatic fluid tube within the tool housing. In one embodiment, the pneumatic motor discharge air is vented from the tool housing in a sealed passage that accommodates the tool compliance motion, and prevents dust infiltration.

Robotic system for picking, sorting, and placing a plurality of random and novel objects

A compliance mechanism for a pick and place robotic system comprising: a motion device, an end effector coupled to the motion device, wherein the end effector comprises a sheath structure, a rod, wherein the compliance mechanism is configured to: when the distal end of the rod is in not contact with an object, causing the distal end of the rod to move responsive to movement of the motion device, and when the distal end of the rod is in contact with an object and the motion device moves toward the object, causing the distal end of the rod to remain stationary by causing the sheath structure to move along a longitudinal direction of the rod.

Rotatable cushioning pick-and-place device

A rotatable cushioning pick-and-place device primarily comprises a motor, a body, a cushioning module and a pick-and-place module. The cushioning module is disposed in a first chamber of the body and comprises a rotary bearing which is connected to a drive shaft of the motor, and coupled to a driven shaft sleeve through a rotary follower. The rotary follower is driven by the rotary bearing to drive the driven shaft sleeve to rotate, thereby allowing the rotary bearing to displace relative to the driven shaft sleeve axially. The cushioning spring is arranged between the rotary bearing and the driven shaft sleeve. A first sealing ring and a second sealing ring of the pick-and-place module are fixed on the body to cooperatively and air-tightly seal the second chamber.
