S6, product quality inspection: and detecting the quality of the product, and sterilizing and packaging the qualified product. (refer to FIG. 6)
In the above embodiment, the balloon 2 is sleeved on the silicone tube 1, and the inner and outer glues 6 and 7 are fixed, and considering that the glue dispensing region is uneven, so that the connection transition between the silicone tube 1 and the balloon 2 is not smooth, therefore, two short heat-shrinkable sleeves 5 are sleeved on the glue dispensing region and are heated towards the end of the balloon 2, after the short heat-shrinkable sleeves 5 and the inner and outer glues 6 and 7 are heated, the short heat-shrinkable sleeves shrink, and the inner and outer glues 6 and 7 are extruded and deformed under the high temperature and the pressure of the short heat-shrinkable sleeves 5 to gradually form the bullet shape, so that the connection between the silicone tube 1 and the balloon 2 becomes smoother, finally, the long heat-shrinkable sleeves 4 are sleeved, the heating process of the short heat-shrinkable sleeves 5 is repeated, and the shape of the glue is further adjusted to meet the requirement of smooth connection degree.
The glue shape is fixed by adopting the mode, and the glue shape does not need to be processed and shaped, so that the assembly cost is low and the efficiency is high. In addition, the silicone tube 1 and the balloon 2 are fixed through glue, the long and short heat-shrinkable sleeves 4 and 5 can also play a role in fixing, and the reliability of connection of the silicone tube 1 and the balloon 2 is fully guaranteed through a triple fixing mode.
In step S1, the silicone tube 1, the balloon 2, the support rod 3, and the long and short heat-shrinkable sleeves 4 and 5 are dried and sterilized with alcohol before being assembled. The drying and the assembly are convenient, the bacteria can be prevented from breeding after the disinfection, and the use safety is improved.
The support rod 3 comprises a rod body 301 and a clamping portion 302 which are coaxial and integrally formed, and the inner diameter of the silicone tube 1 is between the outer diameter of the rod body 301 and the outer diameter of the clamping portion 302. The rod body 301 is used for supporting and positioning the silicone tube 1, and the clamping part 302 is used for fixedly connecting the supporting rod 3.
In step S2, the balloon 2 is spread by a dedicated clamping jaw and then sleeved on the silicone tube 1, and is temporarily fixed by pressing with a pressing block. Adopt special clamping jaw to carry out the pollution that the suit operation of sacculus 2 caused of hand contact can reduce, use sacculus 2 fixed sacculus 2 temporarily, make things convenient for special clamping jaw to take out in the sacculus 2.
In step S3, the supporting rod 3 drives the silicone tube 1 to rotate at a constant speed, and the dispensing operation is performed in cooperation with the dedicated dispensing device. The uniform rotation of the silicone tube 1 can ensure the uniform dispensing and the sticking quality.
Specifically, the thickness of the outer glue 7 is 2 mm. In order to make the glue fully cover the sacculus 2, the sticking effect is ensured.
The long and short heat-shrinkable sleeves 4 and 5 are made of FEP. The FEP long and short heat-shrinkable sleeves 4 and 5 have the advantages of good wear resistance and low friction coefficient, and have no toxic action on human bodies.
In step S6, it is manually detected whether the connection between the balloon 2 and the silicone tube 1 is firm, and whether the connection is bullet-shaped after the glue is fixed.
