Embodiment Construction

[0025] A four-degree-of-freedom parallel sorting robot provided by the present invention includes a frame 5 , a driving device, three motion branch chains and an end effector 7 . The end effector 7 forms a closed-loop parallel structure with the frame 5 through the kinematic branch chain; the kinematic branch chain includes a first branch chain 21, a second branch chain 22, a synchronous belt branch chain 23, and the first branch chain 23. A branch chain 21 includes a first branch chain and a second branch chain; the first branch chain 21 serves as a moving platform for the end effector 7, providing it with two plane degrees of freedom in the X and Y directions; The two branch chains 22 provide the end effector 7 with a rotational degree of freedom around the Z axis; the synchronous belt branch chain 23 transmits torque to the end effector 7 through the synchronous belt, providing it with a plane degree of freedom in the Z direction; The end effector 7 is composed of a lead sc...

The robot comprises a rack, an end effector, a first branched chain, a second branched chain and a synchronous belt branched chain, wherein the first branched chain comprises a first driving arm, a first driven arm, a second driving arm and a connecting rod; the second branched chain comprises a third driving arm, a third driven arm and a third secondary driven arm; the synchronous belt branched chain comprises belt pulleys and synchronous belts; the first branched chain and the second branched chain are connected with driving devices through the driving arms respectively; the synchronous belt branched chain is connected with a fourth driving device through a first belt pulley; the first branched chain, the second branched chain and the synchronous belt branched chain are connected with the end effector. The robot has the characteristics of simplicity in manufacturing, convenience in mounting and debugging, lower manufacturing cost and the like.

Description

Technical field: [0001] The invention belongs to the technical field of industrial robots, and in particular relates to a four-degree-of-freedom parallel sorting robot. Background technique: [0002] In the automated production lines of industries such as light industry, medicine, food, and electronics, operations such as sorting, packaging, and packaging often require manipulators with end effectors that perform high-speed operations in space. General industrial robots are expensive, expensive equipment, not precise enough in structure, relatively large in size, large in space, and heavy in structure, which cannot meet people's high requirements for functionality, small space, light weight, and high precision. At present, most of the four-degree-of-freedom robots of the sorting class belong to the SCARA type or the DELTA type. Although it can meet the industrial requirements, the structure of the SCARA robot is relatively cumbersome, and the DELTA robot takes up a relative...
