A robot includes a first arm rotatable around a first axis and a second arm having an extending direction. The first arm includes a first base and a first extending portion. The first base includes a first through hole passing through the first arm along the first axis. The first extending portion extends from the first base along the first axis. The second arm includes a second base and a second extending portion. The second base includes a connection portion connected to the first extending portion such that the second arm is rotatable around a second axis that is substantially orthogonal to the first axis. The second base includes a second through hole passing through the second arm along the extending direction. The second extending portion is provided opposite to the connection portion in the extending direction and extends from the second base along the extending direction.

Robot

Provided is a robot further improved in safety. The robot includes at least one link which is rotatably coupled around an axis, a motor which rotates the link around the axis, a first sensor which detects a rotation state of the motor, and a second sensor which detects a rotation state of the link. The robot also includes a controller which controls the rotation of the link based on information from the first sensor. The controller determines an operation state of at least one of the first sensor and the second sensor, based on first information from the first sensor and second information from the second sensor.

A robot wrist structure includes a first wrist arm rotatable about a first axis, a second wrist arm provided in a tip end portion of the first wrist arm and configured to swing about a second axis substantially intersecting the first axis, a wrist flange provided in a tip end portion of the second wrist arm and configured to rotate about a third axis in a skew position with respect to the second axis, an intermediate member fixed to the wrist flange, and a cable bundle connected to an end effector fixed to the intermediate member. The cable bundle extends through the second wrist arm, the wrist flange and the intermediate member and drawn out from the intermediate member to reach the end effector.

An articulated manipulator includes a base body, a first arm body, a second arm body having a second arm center axis, and a third arm body. A first joint part connects the base body and a first end portion of the first arm body rotatably around a first rotation axis. A second joint part connects a second end portion of the first arm body and a third end portion of the second arm body rotatably around a second rotation axis. A third joint part connects a fourth end portion of the second arm body and a fifth end portion of the third arm body rotatably around the third rotation axis. When the first, second and third arm bodies are all erected with respect to a installation surface, the first rotation axis, the second arm center axis, and the third rotation axis are substantially aligned with each other.

Articulated manipulator

The present invention is an industrial robot with a cable spanned between and end effector and an upper arm. The cable does not twine around the upper arm or interfere with a peripheral device. A passage opening, through which the cable for supplying power, signals, or materials to an end effector attached to a rotating element is drawn out of a body, is opened at a position where the body intersects the center of a first rotational axis.

Industrial robot

This invention provides a manipulator that can facilitate a teaching method, improve the operation speed of an arm, and mount a heavy load in a narrow space. The manipulator includes a plurality of arm bodies provided in series, joint parts rotatably connecting two adjacent arm bodies, and the joint parts in which slope of rotation axes of the adjacent joints are 90 degrees, at least one linear body disposed in the joint parts coaxially with the rotation axes. The joint parts are composed of a servo motor, and a speed-reduction mechanism. The rotation axes of the servo motor, the speed-reduction mechanism and the joint parts become the same axis.

The present invention provides an industrial robot, wherein a cable or the like spanned between an end effector and an upper arm has less bending due to a motion of a wrist portion, wherein the cable or the like does not twine around the upper arm, and wherein the cable or the like does not interfere with a peripheral device. A passage opening, through which a cable or the likefor supplying power, signals or materials to an end effectorattached to a rotating elementis drawn out of a body, is opened at a position, at which the bodyintersects with a center of a first axis (an R-axis). The cable or the likedrawn out of the passage openingis extended to the end effector

A welding torch having a flange portion to be coupled to a wrist of a robot. A shock sensor is attached to the flange portion. A nozzle is attached to the shock sensor. The welding torch includes a wire feeding pipe socket arranged at a center of the flange portion. A cooling pipe socket is arranged at a position offset from a central portion of the flange portion. A cooling hose for feeding cooling water from the flange portion to the nozzle is provided while bypassing the shock sensor.

Welding torch and welding robot

An arc welding cable that is resistant to bending and twisting and can give a long life is provided. For this purpose, an arc welding cable () for supplying a welding current, a welding wire and a sealed gas from a wire feeding device () to a welding torch (), has a passage () for the welding wire () and sealed gas is located at a center of the arc welding cable and a plurality of conductors () are arranged apart from one another on a circumference around the passage (). The space between the plurality of conductor () may be filled with a cushion material such as cotton or elastic synthetic resin.
