Embodiment 1

[0033] Such as Figure 1 to Figure 4As shown, a feeding assistance robot includes a gripper 5, a mechanical arm 4, and a main body rotating lifting device 6 for driving the gripper 5 and the robotic arm 4 to lift, move back and forth, and swing left and right.

[0034] The gripper 5 includes a gripper housing 51 and a spoon for gripping food arranged at the front end of the gripper housing 51. The gripper housing 51 is hinged with the front end of the mechanical arm 4 and can be positioned relative to the front end of the mechanical arm 4. Described mechanical arm 4 swings up and down.

[0035] The spoon includes a first half scoop 59 and a second half scoop 510, and the first half scoop 59 and the second half scoop 510 cooperate with each other to complete the picking and placing of food. The clamper housing 51 is provided with a clamping driving device for driving the first and second half spoons to separate from each other and to move closer to each other. The clamping dr...

Embodiment 2

[0050] The structure, principle and composition of this embodiment are basically the same as those of the above-mentioned embodiment 1, the only difference lies in the installation position of the rotation driving mechanism and the installation position of the gripper on the arm frame.

[0051] Such as Figure 5 and Figure 6 As shown, in this embodiment 2, the clamper 5 is integrally installed in the arm frame 41 and is in a suspended state, and the clamper housing 51 is rotationally connected with the arm frame 41 through the first transmission shaft 43, so Said rotary drive mechanism comprises a third motor 47, the third motor 47 is arranged on one side of the boom 41, the axis of the output shaft of the third motor 47 is parallel to the axis of the first transmission shaft 43, and the first transmission shaft 43 The rotation is driven by the third motor 47 , thereby driving the holder housing 51 to swing up and down relative to the boom 41 .

Abstract

The invention discloses a feeding assistance robot, which belongs to the technical field of diet care robots, and comprises a gripper, a mechanical arm and a main body rotation for driving the gripper and the robotic arm to perform lifting motion, forward and backward movement and left and right swing as a whole Lifting device, the gripper includes a gripper shell and a spoon for gripping food arranged at the front end of the gripper shell, the gripper shell is hinged with the front end of the mechanical arm and can be moved up and down relative to the mechanical arm Swing, the spoon includes a first half-spoon and a second half-spoon, and a clamping drive device for driving the first and second half-spoons to separate from each other and to move closer to each other is arranged inside the holder housing. The invention has the advantages of simple structure, compact and reasonable layout, flexible operation, good movement coordination of each moving part, and high stability and precision.

Description

technical field [0001] The invention belongs to the technical field of eating care robots, and in particular relates to an eating assistance robot. Background technique [0002] With the continuous development of robot automation technology in our country, the application fields of robots in our country will be very extensive, involving various aspects such as industry, medical treatment and life. In recent years, the number of patients with hand function disabilities caused by stroke sequelae, spinal cord injuries, muscle, nerve and brain lesions, as well as natural and man-made disasters has increased year by year, and the dietary care of hand disabled patients needs to be resolved urgently. [0003] Robot technology has developed rapidly in the last two decades, and the development of a kind of rehabilitation robot called feeding assistance robot has just started, but with the increasing aging of the world population and the increasing number of disabled Increasingly, th...
