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

[0051] Such as figure 2 As shown, the venous needle includes a double-leaf needle base 1, a steel needle 2 and a protective sheath 3.

[0052] Such as figure 1 As shown, the assembly process includes the following steps:

[0053] A. Needle seat feeding: place the double-leaf needle seat 1 in the storage device 1, place the tooling tool on the lower part of the feeding device, and place the double-blade needle seats 1 in sequence through the transmission function of the feeding device 1 Loading to the tool loading tool for positioning; specifically, the feeding device includes a vibration mechanism, a material distribution channel, a blocking mechanism, a rotating bracket, and a feeding manipulator. A pressing block is driven by the pressing mechanism to press the double-leaf needle holder 1 loaded into the tool carrier into place; the side of the distribution channel is provided with a sensor 1 for sensing the double-blade needle holder 1, and the sensor 1 function, thereb...

Embodiment 2

[0077] 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 provides an assembly technology of a medical venous needle and belongs to the technical field of medical devices. The assembly technology of the medical venous needle solves the technical problems that the assembly quality and the assembly efficiency of a product are lower in the prior art. The venous needle comprises a double-vane needle stand, a steel needle and a protective sleeve. The assembly technology comprises the following processes of: A, charging materials to the needle stand, B, assembling the steel needle, C, applying glue, D, drying the glue, E, assembling the protective sleeve, and F, taking out the venous needle. The assembly technology has the advantages of good assembly quality, high assembly 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 the 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 exa...
