Problems solved by technology

The device can automatically assemble the sealing ring on the needle seat, avoiding some defects in manual assembly, but the device uses three mechanisms, namely the support ring mechanism, the transfer mechanism and the pull-off mechanism, to assemble the sealing ring on the needle seat. On the one hand, the overall structure is more complicated, and there are many parts and components, which increases the cost of production and maintenance, and the market competitiveness is weak

Abstract

The invention provides an assembly device for a needle stand seal ring of a safe self-destruction type injector assembly machine, belongs to the technical field of medical apparatus and instruments, and solves the technical problems of complicated integral structure, weak market competition and the like in the prior art. The assembly machine comprises a frame, wherein the frame is provided with upper and lower rotary tables which are connected with a dynamic mechanism and can rotate synchronously. The assembly device comprises a grab bar which is arranged on the upper rotary table and used for positioning a needle stand, and the lower rotary table is provided with a circling mechanism which can receives a seal ring on a feeding mechanism and can open the seal ring along with the rotation of the lower rotary table; and when the seal ring is opened to a state that the inner diameter of the seal ring is greater than the outer diameter of the needle stand, the circling mechanism can sleeve the seal ring on the needle stand under the action of the lower rotary table. The assembly device ensures that the whole structure of the assembly machine can be simpler, saves production cost, and improves market competition.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a safety self-destruction syringe assembly machine, in particular to a needle seat sealing ring assembly device of the safety self-destruction syringe assembly machine. Background technique [0002] The latest generation of disposable self-destructing syringes sold in the market generally include a needle cylinder body, a needle seat, a rubber stopper and a needle rod. The front end of the pull rod is movably inserted into the needle cylinder body from the rear end of the needle cylinder body. After the liquid medicine in the syringe body is transfused, the front end of the needle pull rod is snapped into the needle holder, and the needle pull rod is pulled back, and the needle holder and the needle head arranged on it are pulled into the body simultaneously and the needle pull rod is pulled off at a specific position. In order to have a good seal between the needle seat a...
