A kind of bionic hand and preparation method thereof

Abstract

The invention discloses a bionic hand and a preparation method thereof. The hand comprises a palm mechanism, a thumb mechanism, an index finger mechanism, a middle finger mechanism, a ring finger mechanism and a small thumb mechanism, the thumb mechanism, the index finger mechanism, the middle finger mechanism, the ring finger mechanism and the small thumb mechanism are internally provided with aplurality of support blocks and pull wires, and the pull wires are respectively connected to a stepping motor after penetrating through the support blocks for achieving the control of the finger mechanisms. The hand has low manufacturing cost, short production cycle and complete customization.

Description

technical field

[0001] The invention belongs to the technical field of robots, and in particular relates to a bionic hand and a preparation method thereof. Background technique

[0002] The bionic hand is the key functional part of the increasingly developed artificial robot, and it is also a strong demand of the disabled with handicap. Existing bionic hands mainly include the following two categories:

[0003] The first category is relatively flexible in function, but obviously mechanized in appearance, such as the hand of an intelligent robot in a science fiction film. This type of hand is mainly based on the shape of the human hand, through computer modeling software, the structure of the hand is disassembled, and the irregular biological joints of the human hand are replaced with standardized mechanical joints. The advantage of this implementation method is that all the movable joints of the human hand can be split, so as to achieve more degrees of freedom, so as to ap...

Examples

preparation example Construction

[0043] The preparation method of a kind of bionic hand of the present invention, adopts mechanical design and silica gel injection molding combination, comprises the following steps:

[0044] S1, first use the existing technology to prepare a silicone hand mold;

[0045] S2, according to the size of each joint on the hand, use low melting point paraffin to make a joint disappearing wax model for each joint;

[0046] S3. According to the length of each knuckle bone of the finger, the internal cable tube is intercepted;

[0047] S4. The internal cable and the supporting iron wire are passed through in sequence according to the corresponding positional relationship between the cable tube corresponding to the length of the knuckle bone and the wax block of the lost joint, and the shape is folded according to the center line of the corresponding finger, and the appropriate position of each finger is Insert the positioning wire according to the diameter of the corresponding positio...
