Introduction of syringe assembly machines

The syringe assembly machine is a new type of medical automatic assembly equipment, suitable for the production and assembly of disposable syringes. Its appearance realizes the automatic assembly of syringes, effectively reduces labor costs, and greatly shortens the wasted time, making the production of disposable syringes more efficient.

Currently, disposable syringes have been widely used in medical systems. When using a disposable syringe, the syringe does not need to be sterilized, and the user only needs to tear off the outer packaging. Therefore, it has the advantages of convenient use, safety and hygiene, and is loved by the majority of users. However, this requires high hygiene requirements for the production of disposable syringes.

Existing disposable syringes are usually composed of four parts: injection rod, syringe, rubber stopper and needle. For the assembly of these four parts, for the assembly of the four parts, the traditional method is manual operation. The biggest disadvantage is that the syringe is easy to adhere to germs, resulting in unqualified product hygiene. At the same time, the assembly speed of manual operation is also low, so many people start to design and research the automatic syringe assembly machine.

In the currently designed and developed automatic syringe assembly machine, the assembly of the syringe accessories is realized by the principle of pneumatics. In other words, it relies on the piston in the cylinder to fix the syringe fittings and assembles through the reciprocating movement of the piston. The pneumatic assembly device has a complicated structure and the cost of the assembly machine is high; at the same time, the noise of the piston in the cylinder is very high during the movement, the assembly machine runs unevenly and the assembly speed is slow.
