Spoon clamping mechanism on medical rehabilitation robot

Abstract

The invention discloses a spoon clamping mechanism on a medical rehabilitation robot. The mechanism comprises a supporting sleeve, wherein a lower clamping block and an upper clamping block are inserted into the supporting sleeve, a D-shaped lower screw rod is screwed on the rear end face of the lower clamping block, the rear end of the lower screw rod penetrates through a circular positioning plate to be in threaded fixed connection with a limiting sleeve, and the positioning plate is inserted into the supporting sleeve; a D-shaped upper screw rod is screwed on the rear end face of the upperclamping block, the rear end of the upper screw rod penetrates through the positioning plate to be in threaded fixed connection with a magnetic trigger block, the parts, on the two sides of the trigger block, of the positioning plate are fixedly provided with support columns, the rear ends of the support columns are fixedly provided with a connecting plate, an electromagnet opposite to the triggerblock is fixedly connected to the connecting plate, the upper screw rod is sleeved with a spring, the two ends of the spring are pressed against the positioning plate and the upper clamping block correspondingly, a jackscrew is inserted into the supporting sleeve, and the jackscrew is screwed in the lower clamping block.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a spoon clamping mechanism on a medical rehabilitation robot. Background technique [0002] Medical robots refer to robots used for medical treatment or auxiliary medical treatment in hospitals and clinics. It is an intelligent service robot, which can independently program the operation plan, determine the action program according to the actual situation, and then turn the action into the movement of the operating mechanism. At present, there are some machines that can assist patients in their rehabilitation, such as a rehabilitation robot that assists patients in catering. The rehabilitation robot consists of a dinner plate and a multi-joint mechanical arm connected to the plate. The end of the mechanical arm can hold and fix tableware such as spoons. The manipulator can help patients to eat by themselves. At present, the upper end of the above-mentioned rehabilitati...

Problems solved by technology

At present, there are some machines that can assist patients in their rehabilitation, such as a rehabilitation robot that assists patients in catering. The rehabilitation robot consists of a dinner plate and a multi-joint mechanical arm connected to the plate. The end of the mechanical arm can hold and fix tableware such as spoons. The manipulator can help patients eat by themselves. At present, the upper end of the above-mentioned rehabilitation robot’s mechanical arm is located at the mechanical gripper. The mechanical gripper is not only complicated in structure, but also inconvenient for tableware such as spoons, so it is necessary to design a special clamping mechanism.
