Abstract: A sealing arrangement for application in a robot joint. The sealing arrangement includes: a circular sealing assembly arranged between a swing and a base of the robot joint in a longitudinal direction, the circular sealing assembly defining a tubular cavity in a circumferential direction and having a gas inlet and a gas outlet; and an air channel coupled to the gas inlet and operable to continuously conduct pressured air flow into the cavity to maintain an air pressure inside the cavity above an air pressure outside the cavity, and thereby a high-speed airflow out of the gas outlet.

Abstract: Present disclosure provide an apparatus for holding cables of a robot and a robot. The apparatus comprises a body extending along an axis and comprising a circumferential wall to space the cables arranged in the body from a first part of the robot; and a slit formed on the circumferential wall across an entire length of the circumferential wall along the axis, the slit adapted for the cable to pass through radially to allow the cables to be arranged in the body. With the slit formed across the entire length of the circumferential wall along the axis, the cables can be easily arranged in the body radially through the slit. In this way, the cables can be arranged in the apparatus without having to remove the large connector, thereby improving assembly efficiency. In addition, since the connector does not need to be removed, the connection performance is also improved.

Abstract: A stopper apparatus for robot rotary joint, for limiting the rotation angle of a turning shaft. The stopper apparatus includes: a rotary protrusion, fixed to the shaft and extended from an outer circumference surface of the shaft; a ring-like orbit, fixed to a mounting housing of the robot rotary joint, inserting the shaft therein; a first slider and a second slider, rotatably accommodated in the orbit and able to push each other to rotate; a stop protrusion, fixed to the housing of a robot rotary joint and extended in the direction of the center of the shaft; the rotary protrusion is able to directly push the second slider to rotate, while it is not able to directly push the first slider to rotate; the shaft, the rotary protrusion and the second slider cannot be obstructed by the stop protrusion when rotate, while the first slider is able to be obstructed by the stop protrusion when rotate, thereby the relative rotation between the shaft and the housing can be stopped. The present invention also provides a rotary joint and a robot. Compared with the existing prior arts, the proposed solution enables a rotation range larger than ±360 degrees.

Abstract: A robot joint and a robot using the robot joint is provided. The robot joint includes a first part and a second part configured to be rotatable with each other around a joint axis. A flexible printed circuit board is further included with a first fixing point and a second fixing point respectively fastened to the first part and the second part. The flexible printed circuit board is spiral-shaped prior to bending. With the relative rotation of the first part and the second part, the flexible printed circuit board is bent at various bending portions. This makes the robot joint more compact with a larger rotation range and a long lifetime in a cost effective way.
