Problems solved by technology

[0002] The disposable infusion needles currently used are all assembled by hand, and the needles are loaded manually, that is, the needle tube is manually installed on the infusion needle seat. This assembly status makes the work efficiency low and easily causes pollution of the infusion needle products.
At present, there is no mechanical assembly equipment in China, especially the orientation technology of mechanized assembly of infusion needles has not been solved.

Embodiment

[0018] The mechanized needle loading technology for infusion needles described in this embodiment is to set up and control the orientation of the beveled surface of the needle head during the flow of the needle tube, so as to complete the oriented slope in which the beveled surface of the needle tip of the infusion needle is basically parallel to the wing surface of the needle seat. flat. The directional inclined plane contains continuous transitional inclined planes in the stepped parallel grooves, and the transitional inclined planes are made of materials containing metal or non-metal or a combination of metal and non-metal. After the needle tube slides down the groove, it rotates around its own axis due to vibration. When the inclined surface of the needle point and the oriented inclined plane meet, the needle tube no longer rotates, ensuring the orientation of the needle tube. The infusion needle is shown in Figure 1 and Figure 2.

Abstract

The invention provides a method of mechanical assembly of infusion needle, which comprises setting a predetermined inclined surface in the needle convey route to allow an inclined plane produced by grinding the needle tube tip substantially parallel to the plane of the needle base wing; conveying the needle tube to a preset position; vibrating to make the needle tube rotate; and positioning the needle tube by stopping rotation until the needle tip inclined plane engages with the predetermined inclined surface. The invention solves the problems of needle tube positioning and assembly, and integrates the processes of needle grinding, needle positioning, needle clamping, and needle insertion, thereby increasing the work efficiency greatly.

Description

technical field [0001] The invention relates to a production technology for infusion needles, in particular to a mechanized needle tube loading technology for infusion needles and a device thereof. Background technique [0002] The disposable infusion needles used at present all rely on manual assembly and manual loading, that is, the needle tube is manually installed on the infusion needle seat. This assembly status makes it low in work efficiency and easily causes pollution of the infusion needle product. At present, there is no mechanical assembly equipment in China, especially the orientation technology of mechanized assembly of infusion needles has not been solved. The needle bevel (needle surface) of the infusion needle cannot be parallel to the needle seat and keep the direction of the needle surface unchanged. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical assembly device to realize the automatic needle loading of...
