example 1

[0042] Example 1: A manufacturing process of a single-airway polymer soft finger, comprising the following steps:

[0043] Step 1: In the mold with polytetrafluoroethylene as the matrix, spray a certain amount of release agent in the mold to ensure that the obtained rubber can be easily and completely separated from the mold.

[0044] Step 2: Configure the Ecoflex 00-30 prepolymer mixture, put it in the ultrasonic vibration pool for 5 minutes, and put it into the mold with a pouring weight of 22g.

[0045] Step 3: Put the mold in a vacuum drying oven to evacuate to remove air bubbles. After no bubbles are produced on the surface of Ecoflex00-30, put the mold in a 60°C electric constant temperature blast dryer for constant temperature curing for 30 minutes.

[0046] Step 4: Take out the mold and put it into a cylindrical mold of a certain size. Prepare 15g of PDMS with a mass ratio of prepolymer and curing agent of 10:1, and place it in an ultrasonic vibration pool for 5 minut...

[0048] Example 2: A manufacturing process of a single-airway polymer soft finger, comprising the following steps:

[0049] Step 1: Spray a certain amount of release agent in the mold with polytetrafluoroethylene as the matrix to ensure that the obtained rubber can be easily and completely separated from the mold;

[0050] Step 2: Prepare 15g of PDMS with a mass ratio of prepolymer and curing agent of 10:1, and place it in an ultrasonic vibration pool for 5 minutes. Put the PDMS prepolymer mixture in the mold.

[0051] Step 3: Put the mold into a vacuum drying oven to evacuate and keep the vacuum state for 15 minutes to remove air bubbles. After no bubbles are generated on the PDMS surface, the mold is placed in a 60°C electric constant temperature blast dryer for constant temperature curing for two hours.

[0052] Step 4: Take out the mold and put it into a cylindrical mold of a certain size. Then pour the Ecoflex00-30 prepolymer mixture into the mold, and the pouring weigh...

Abstract

The invention provides a manufacturing technology of single-airway macromolecular soft fingers. The single-airway macromolecular soft fingers are formed by compositing PDMS (polydimethylsiloxane) rubber and Ecoflex 00-30 rubber, wherein an air cavity is formed between the PDMS rubber layer and the Ecoflex 00-30 layer. The manufacturing technology comprises the following steps: pouring one rubber into a mold cavity of a finger die, and curing to form a lower rubber layer; positioning a cylindrical die used for forming the air cavity on the cured rubber layer; pouring another rubber into the die, and curing to form an upper rubber layer; and then removing the cylindrical die to obtain the macromolecular soft fingers. The manufacturing technology of the single-airway macromolecular soft fingers is high in changeable-environment compliance, and high in safety; the single-airway macromolecular soft fingers are formed by compositing two types of rubber; the rubber, which is light in mass and high in flexibility, is used as the basic material, so that the single-airway macromolecular soft fingers are applicable to the man-machine interaction field.

Description

technical field [0001] The invention relates to a manufacturing process of a soft finger, in particular to a manufacturing process of a single airway polymer soft finger. Background technique [0002] With the development of science and technology, robots have penetrated into the fields of processing and manufacturing, medical care, aerospace and social services, assisting human beings to complete tasks that are difficult for humans to complete, reducing human labor intensity, and improving human working and living conditions. With the aging of society and the decline of people's physical health, the demand for automated and intelligent equipment in the medical and service fields has increased. For example, patients need lighter and safer hand and limb rehabilitation equipment, and families with heavy pension burdens There is a need for intelligent devices that can handle more of the problems of everyday life. It can be seen that humanoid, medical and service robots have co...
