Needle assembly machine

Abstract

The invention relate to the technical field of medical instruments, in particular to a needle assembly machine. The machine comprises a machine frame, wherein a support plate is arranged at the top ofthe machine frame, a rotary table is arranged at the center of the support plate, and a first motor driving the rotary table to rotate stepwise is arranged in the machine frame; a pintle feeding device, a needle tip feeding device, a needle tip aligning device, a pressing device and a sheath sleeving device which are arranged in the rotating direction of the rotary table are arranged around the rotary table on the support plate; a plurality of fixtures are distributed uniformly circumferentially on the rotary table. The rotary table is used for driving the fixtures to pass through the pintlefeeding device, the needle tip feeding device, the needle tip aligning device, the press mounting device and the sheath sleeving device sequentially, automatic pintle positioning, needle tip placement, alignment, press mounting, sheath sleeving and blanking are realized, and accordingly, continuous needle assembly is realized, assembly time is shortened, investment of manpower and material resources is reduced, assembly cost is greatly reduced, and production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a needle assembly machine. Background technique [0002] In clinical medical devices, syringes are widely used, and the most important component of the syringe is the needle. The needle assembly process used at the earliest was done manually, and later it was gradually converted to semi-automatic assembly, that is, manual positioning of the needle plug. , Manual placement of the needle tip, manual alignment, the press-fitting part is completed by machinery, and finally a sheath is put on to prevent contamination. Since the needle directly enters the human body, it requires high assembly quality. Manual assembly has defects such as poor workmanship and no guarantee of quality. In addition, the semi-automatic assembly method requires long hours of work and causes a lot of waste of manpower and material resources. The assembly cost is high and the efficiency is low. As th...

Since the needle directly enters the human body, it requires high assembly quality. Manual assembly has defects such as poor workmanship and no guarantee of quality. In addition, the semi-automatic assembly method requires long hours of work and causes a lot of waste of manpower and material resources. The assembly cost is high and the efficiency is low. As the market demand for products continues to increase, this method can no longer meet the market demand.
