Problems solved by technology

[0007] The assembly process of the above-mentioned intravenous infusion needle assembly can realize the rapid and efficient automatic assembly of the intravenous infusion needle, but the technical problems that have not been solved by the existing automatic assembly process of the intravenous infusion needle are: 1. The positioning and transportation of the raw materials of the double-leaf needle seat are inconvenient ; 2. It is difficult to control the orientation of the inclined surface of the needle blade of the infusion needle, resulting in increased product scrap due to the deviation of the needle position; 3. The amount of glue applied to the infusion needle and the seat is not easy to detect and control

Embodiment 1

[0054] Such as figure 2 As shown, the venous needle includes a double-leaf needle holder 1 , a steel needle 2 and a protective sheath 3 .

[0055] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the assembly process includes the following steps:

[0056] A. Assembling the double-leaf needle seat: place the blade part 11 in the feeding mechanism 1, place the needle tube part 12 in the feeding mechanism 2, place the tooling tool in the lower part of the feeding device, and pass it through the feeding device 1. The function is to load the blade parts 11 sequentially and orderly on the tool carrier for positioning; the needle tube part 12 is taken out from the feeding mechanism 2 by the assembly manipulator and sent to the gluing mechanism for gluing, and then the needle tube part 12 is assembled by the assembly manipulator. Assemble with the blade part 11 on the tool carrier, and then dry the glue to fix the above two to form the double-blade needle holder 1...

Embodiment 2

[0082] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, process D also includes the second automatic correction step of the steel needle blade surface: the tool carrier is transported through the transmission belt Go to the second place of the CCD industrial camera, take pictures of each steel needle 2 on the tool carrier through the second CCD industrial camera, and transmit the image data to the intelligent identification system, and identify the position of the steel needle blade surface 21 through the intelligent identification system And compare it with the standard blade surface 21 position set by the system, so as to calculate the phase difference angle between the two and convert it into a servo signal, and perform secondary rotation correction on the unqualified steel needle 2 through the servo motor. Through the automatic secondary correction, the labor production effi...

Abstract

The invention discloses an assembly technology of a split type medical intravenous needle, and belongs to the technical field of medical equipment. The assembly technology resolves the technical problems that in the prior art, assembly of products is low in quality, efficiency and the like. The split type medical intravenous needle comprises a double-vane needle base, a steel needle and a protective sleeve, wherein the double-vane needle base is of a split structure and comprises a vane portion and a needle inserting tube portion. The assembly technology comprises the following working procedures of A assembly of the double-vane needle base, B assembly of the steel needle, C gluing, D gluing drying, E assembly of the protective sleeve and F discharging. The assembly technology has the advantages of being good in assembly quality, high in production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical venous needle, in particular to an assembly process of a split medical venous needle. Background technique [0002] The intravenous needle is an important part of the infusion set, which is used to pierce the patient's vein and introduce the medicinal liquid into the vein. Existing venous needles include needle bases, steel needles and double blades. For example, a Chinese patent [Patent No. ZL200820018844.9; Authorized Notice No. CN201164629Y] discloses a venous needle, which has a needle body, the front end of the needle body is a needle point bevel, and a needle handle is arranged on the rear end of the needle body, facing upward in the direction of the needle point bevel. The hour hand handle is located on the left side of the rear end of the needle body. [0003] In the prior art, the needle handle of the venous needle can also adopt a double-leaf type, for...
