Example Embodiment

[0043] The preparation method of the bionic hand of the present invention adopts mechanical design and silicone injection molding and includes the following steps:

[0044] S1. First use the existing technology to prepare the 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. Cut the inner cable tube according to the length of the bones of each segment of the finger;

[0047] S4. The internal pulling wire and supporting wire are passed through the wire tube corresponding to the length of the knuckle bone and the corresponding positional relationship of the lost foam wax block, and their shape is folded according to the center line of the corresponding finger, and placed in the appropriate position of each finger. The position is based on the diameter of the corresponding finger and the positioning wire is inserted. This is the internal skeleton of the five ...

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...
