Robot shoulder device

Abstract

The invention discloses a robot shoulder device. The robot shoulder device is installed on a back plate in a robot body. The robot shoulder device comprises an arm rising mechanism and an arm swing mechanism. A shoulder of a robot is installed on the outer side of the arm swing mechanism. The arm rising mechanism comprises a U-shaped arm rising base fixed to the back plate, and an L-shaped arm rising motor base. An opening of the U-shaped arm swing base faces the inner side. A rotary shaft perpendicular to the back plate is arranged between two side plates of the U-shaped arm rising base. Theend, close to the back plate, of the rotary shaft is sleeved with a driven belt pulley, and the other end of the rotary shaft is fixedly provided with an arm swing mechanism. An arm rising motor is fixed to a side plate of the L-shaped arm rising motor base. An output shaft of the arm rising motor is sleeved with a driving belt pulley. The driving belt pulley and the driven belt pulley are in transmission connection through a conveyer belt. With the robot shoulder device, arm rising actions, arm swing actions and large-torque load bearing of shoulder joints of the robot can be achieved; and atthe same time, effective utilization on the limited space of the shoulder part is achieved, the personification state of the shoulder of the robot is guaranteed, and the cost for driving the shoulderis reduced.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot shoulder device. Background technique [0002] With the continuous advancement of science and the development of artificial intelligence technology, the development of intelligent service robots has come. With the continuous development of service robots, they have gradually entered human life and brought more convenience to people. , more comfortable service. [0003] For service robots, the robot's shoulders are crucial, carrying the weight of the entire arm. For service robots, the manipulator needs to grab various items and carry loads of different sizes. However, most of the shoulders of existing service robots are driven by steering gear, and the lower-priced steering gear is used for driving. , can only be used for demonstration purposes, and cannot be used to capture loads.

Problems solved by technology

For service robots, the manipulator needs to grab various items and carry loads of different sizes. However, most of the shoulders of existing service robots are driven by steering gear, and the lower-priced steering gear is used for driving. , can only play a demonstration role, and cannot grab the load

Even if a steering gear that can output loads is used, there are still large shoulders caused by the large volume of the steering gear, and the structure is too complicated to achieve an anthropomorphic state; at the same time, the price and cost of such a steering gear that can output loads is very high and cannot be widely used
