  • Publication number: 20240116196
    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.

  • Publication number: 20240116194
    Abstract: An integrated joint module includes a housing, a driving assembly, a speed reduction assembly, a braking assembly and an encoding assembly. The housing includes a first housing and a second housing, an annular supporting platform is arranged on an inner side of the first housing. The driving assembly includes an output shaft, a stator embedded in the annular supporting platform, and a rotor connected with the output shaft and arranged on an inner side of the stator, the speed reduction assembly and the braking assembly are connected with two ends of the output shaft. The encoding assembly is arranged on a side of the braking assembly away from the driving assembly and connected with the output shaft, the second housing is sleeved on the encoding assembly and connected with the first housing. The integrated joint module helps to simplify the structure of the joint module and reduce the cost.

  • Patent number: 11820012
    Abstract: A joint module is provided which includes a housing, a driving assembly, a speed reduction assembly, a first fastener, a second fastener and a third fastener. The driving assembly includes an output shaft, a lower bearing seat and a lower bearing, an inner ring and an outer ring of the lower bearing are respectively connected with the output shaft and the lower bearing seat. The first fastener fixes the lower bearing seat on the housing, and the second fastener fixes the speed reduction assembly on the housing. The third fastener fixes the input shaft of the speed reduction assembly to the output shaft. The output shaft of the driving assembly and the input shaft of the speed reduction assembly are separate structural members, which not only allows the driving assembly and the speed reduction assembly to be tested separately before assembly, but also facilitates the later maintenance.
