Problems solved by technology

However, all kinds of pneumatic flexible fingers developed by various enterprises and institutions currently adopt integral structural forms. The existing problems are: the action form and control method are single and fixed, and lack diversity and flexibility. If the use conditions and requirements change, Only by redesigning and manufacturing new pneumatic flexible fingers

Embodiment Construction

[0018] The combined pneumatic flexible finger of the present invention is mainly composed of silicone finger block A 6, silicone finger block B 7, branch trachea 11, connecting trachea 12, silicone finger segment 16, fingertip 15, cable tie 14, and blue butyl rubber 19.

[0019] First, use a 3D printer or a mechanical processing method to manufacture upper mold A 1 , lower mold A 2 , upper mold B 3 , and lower mold B 4 . Pour the liquid silicone into the mold in a vacuum box to exclude air from the liquid silicone. After the silicone finger block in the mold is solidified and formed, take it out, remove and clean the excess parts such as gates and risers on the silicone finger block.

[0020] Put the branch trachea 11 and the connecting trachea 12 into the air hole 5 of the silicone finger block and bond them with liquid silicone, apply liquid silicone evenly on the joint surfaces of the silicone finger block A 6 and the silicone finger block B 7, close them and stick them tog...

Abstract

The invention provides a combined type pneumatic flexible finger. Silicon finger blocks are subject to vacuum pouring and molding in a mold, branch air pipes, communication air pipes and the silicon finger blocks are bonded through liquid-state silica gel, and silicon finger segments are formed; the silicon finger segments are freely combined, the mounting angle is adjusted, and after assembling is carried out, the segments are tightened through ribbons; the branch air pipes or communication air pipes of the silicon finger segments are selectively blocked, compressed air is led in through the corresponding branch air pipes or communication air pipes, deformation bending of the silicon finger blocks can be freely controlled, and various different actions are completed; and according to the combined type pneumatic flexible finger, various use conditions and requirements can be met to be maximum limit, and the soft characteristic of the finger is particularly suitable for objects like a fragile target not properly used by a traditional mechanical arm.

Description

technical field [0001] The invention relates to a combined pneumatic flexible finger, which can be freely combined and formed according to the conditions and requirements of use, and can complete various actions. Background technique [0002] Traditional manipulators are usually driven by electric motors or hydraulic pressure, and perform various actions through mechanical transmission mechanisms. The structure is complex, the space size is large, the control is cumbersome, and the price is expensive. It is easy to cause damage to brittle targets during work. Pneumatic flexible fingers are mainly made of soft materials such as silica gel and rubber. Driven by compressed gas, the inner cavity of the finger expands, deforms and bends the finger, and completes various actions. This technology largely fills in the shortcomings of traditional manipulators. However, all kinds of pneumatic flexible fingers developed by various enterprises and institutions currently adopt integral ...
