Abstract:
A gripping device, which is provided, in particular, as an effector for an industrial robot comprises first and second clamping jaws, which are arranged so as to be moveable relative towards each other in order to grasp a workpiece. The first clamping jaw is provided with a tongue projection and the second clamping jaw with a corresponding groove, which at least partially accommodates the tongue projection in the state in which the clamping jaws are moved towards each other in order to prevent objects or body parts from being inadvertently inserted into the space between the clamping jaws.
Abstract:
A sensor or switch mechanism is connected to a gripper mechanism and uses a pivotal cam link connected to the driving mechanism of the gripper. A cam slot in the cam link is configured to convert linear reciprocal motion of the driving mechanism of the gripper to amplified rotational motion of the pivotal cam link. A target on the cam link and a stationary sensor positioned proximate to an arc described by the target on rotation of the cam link allows the sensor or switch mechanism to distinguish between the gripper properly gripping a single workpiece and the gripper improperly gripping no workpiece and/or two or more workpieces.
Abstract:
The present disclosure provides a post position adjustment device, a cassette adjustment device and a substrate conveyance system. The post position adjustment device includes: a post-picking-and-placing unit configured to pick a post out from current positioning hole and install the post into a target positioning hole; a movement mechanism configured to move the post-picking-and-placing unit; and a movement control unit configured to control the movement mechanism to move the post-picking-and-placing unit to a source position where the post is currently located, and after the post has been picked out from the current positioning hole by the post-picking-and-placing unit, control the movement mechanism to move the post-picking-and-placing unit to a target position.
Abstract:
The conveyor system of the present invention comprises a conveyor robot having a hand and arm, and a pair of gripping jigs attached to a conveyed object. The hand of the conveyor robot comprises a body part attached to an arm, a pair of projecting parts projecting out from different positions of the body part in the same direction, hook parts provided on the pair of projecting parts, and pushing parts attached to the body part adjoining the pair of projecting parts and configured to move along the projection direction of the pair of projecting parts to generate a pushing force. Each gripping jig attached to a conveyed object comprises of a pushed part pushed by a pushing part of the hand, and a rod-shaped part caught on a hook part of the hand.
Abstract:
A gripping or clamping device for gripping or clamping objects has at least one actuator that can be driven by a drive, at least one jaw, and a transmission provided between the actuator and the jaw, wherein the force produced by the drive is transmitted to the object at least by means of a force transmission element provided on or formed by the transmission and/or the clamping means, wherein the force transmission element has a force conducting section. A clamping element that permits an elastic flexibility in the force transmission direction is provided between the force conducting section and the force transmission element.
Abstract:
A self-centering clamp having three jaws, for the industrial automation field and particularly adapted to equip robotic arms, is described.One of the jaws is controlled by a cursor directly activated by the clamp actuator, that can be electric, pneumatic, oleopneumatic, etc. The other two jaws are controlled by corresponding transfer levers kinematically coupled to the cursor. Unlike the conventional arrangements, the levers rotate in a lying plane parallel to the handling plane of the jaws and the cursor. Therefore, the clamp is not very bulky in height and has low weight.
Abstract:
Gripping device (4) and robot arm (2) to which such a gripping device (4) is attached. The gripping device (4) consists of a housing (6) and two gripping finger sockets (9,10) which can be displaced linearly with respect thereto. Each gripping finger socket (9, 10) is provided with an electric or pneumatic coupling by means of which various gripping fingers (17, 27, 37) can be connected. A rotating drive (13) is present between the gripping finger sockets (9, 10) on which a tool can be placed for releasing or attaching a fastening means, such as a bolt. By means of this relatively simple construction, weights of several hundreds kilos can be lifted and positioned accurately, for example in a processing machine.
Abstract:
In a gripping device, a displacement-type force sensor is provided on a side of a driving mechanism opposite fingers to which the driving mechanism is connected to form a grip section. The driving mechanism is supported on a housing with an elastic member being disposed therebetween at a position closer to the fingers than the center of gravity of the grip section.
Abstract:
The methods and devices of the invention include an encoder, an endoscopic robotic instrument, and an encoder/robotic instrument interface. A preferred embodiment of the encoder has a chest/shoulder plate provided with telescoping tubes and joints. Each joint is provided with a direct drive potentiometer to monitor movement and provide a corresponding signal. The chest plate is preferably adaptable to a large range of human-chest sizes and the telescopic segments are strapped to the arms of the practitioner at the elbows. A pistol grip is provided at the wrist end of the telescopic segments. According to the presently preferred embodiment, the encoder encodes flexion and rotation at the shoulder, elbow and wrist of each arm in addition to gripping at each hand. The encoding device is coupled to a circuit which operates a servo system. The servo system includes a series of servo motors. A series of pulleys corresponding to the number of servo motors are arranged in a housing. The robotic instrument preferably comprises two arms mounted at the distal end of a multi-lumen tube. Each arm has rotational and flexional joints corresponding to the shoulder, elbow, and wrist of the practitioner. Tendons are coupled to the pulleys of the servo motors and are fed through the multi-lumen tube to the joints of the two arms.
Abstract:
A chemical (coating and reduction)/mechanical/electrical treatment of ion-exchange materials (preferably ion-exchange membranes) to convert them to artificial muscles. The figure is a perspective view of an actuator of the invention showing the treated membrane actuator (A) with electrodes (25 and 26) placed at one end of the membrane, the electrodes being further attached to a power source (35). Artificial muscles created by the inventive method are capable of undergoing electrically-controllable large deformations resembling the behavior of biological muscles. A typical flap muscle of 0.2-0.4 mm thickness, 2-5 mm width and 20 mm length manufactured by the inventive process can achieve a completely reversible maximum deflection of 12-15 mm under a maximum voltage of 2.0-2.5 volts.
