Abstract
The present disclosure provides a collaborative robot arm and a joint module. The joint module includes a housing, a driving assembly, and a multi-turn absolute encoder. The joint module detects the angular position of the output shaft and records a number of rotating revolutions of the output shaft only by means of the multi-turn absolute encoder. The multi-turn absolute encoder includes a base, a bearing, a rotating shaft, an encoding disk, and a circuit board, the encoding disk is rotatably connected with the base by the rotating shaft and the bearing, the circuit board is fixedly connected with the base, and the reading head on the circuit board detects the angular position of the output shaft cooperatively with the encoding disk, making the multi-turn absolute encoder be an integrated structure. The base and the rotating shaft are detachably connected with the housing and the output shaft respectively.
