Problems solved by technology

This device can only perform directional arrangement and feeding of single-leaf needle holders, but cannot realize directional feeding of double-blade needle holders
Due to the particularity of the shape of the double-leaf needle seat, in the process of assembling the double-leaf injection needle, the assembly of the double-leaf injection needle is done manually. This method is not only slow, but also easy to cause damage to medical accessories. Pollution

Embodiment 1

[0039] The directional feeding device of the needle holder is mainly used for the reversing of the double blade 17 needle holder. Such as Figure 9 As shown, the double blade 17 needle hub includes a tubular needle handle 16 and two blades 17 connected to the outer wall of the needle handle 16 , and there are two strip-shaped opening grooves 161 on the needle handle 16 .

[0040] Such as figure 1 and figure 2 As shown, the directional feeding device of the needle seat includes a frame 1, on which a detection seat 2, a reversing seat 3 and a feeding platform 14 are fixed, and the top of the detection seat 2 has a strip-shaped detection plate 22. The detection board 22 is arranged horizontally, and the upper surface of the detection board 22 is provided with a plurality of positioning grooves 21 , and the positioning grooves 21 are evenly spaced along the length direction of the detection board 22 . A number of parallel feed slots 141 are arranged side by side on the feed pl...

Embodiment 2

[0048] The structure and principle of this embodiment are basically the same as that of the first embodiment, except that the detection structure includes a camera mounted on the frame 1 capable of taking pictures of the needle seat in the positioning groove 21 and a controller connected to the camera. A camera is arranged above each positioning groove 21, and the camera acquires an image of the orientation of the needle holder in the positioning groove 21 and sends it to the controller, and the controller judges the orientation of the needle holder.

Embodiment 3

[0050] The structure and principle of this embodiment are basically the same as that of Embodiment 1 or Embodiment 2. The difference is that the rotating base 4 is block-shaped, the bottom of the rotating base 4 is connected with the driving part, and the positioning mechanism is included on the upper part of the rotating base 4. The surface is provided with a fixed groove, and the bottom of the fixed groove is provided with an air suction hole, and the air suction hole is connected with an air suction pump. The needle seat is prevented from being in the fixed groove, and the suction pump generates negative pressure in the suction hole, which makes the needle seat firmly adsorbed in the positioning groove 21, and prevents the needle seat from being caught by the rotating seat 4 during rotation. throw out.

Abstract

The invention provides a directional feeding device for needle holders, which belongs to the technical field of medical accessory assembly machines. It solves the technical problem that the assembly of the existing double-leaf injection needles is done manually and the assembly speed is slow. The directional feeding device of the needle seat includes a frame, on which a detection seat and a reversing seat are fixed, and a positioning groove capable of locating the needle seat is provided on the top of the detection seat, and a positioning groove capable of detecting the needle seat is also provided on the detection seat The detection structure of the orientation of the inner needle seat. The reversing seat is provided with a rotating seat that can rotate on the reversing seat and a driving member that can drive the rotating seat to rotate. The rotating seat has a positioning structure that can position the needle seat. On the frame A transfer mechanism capable of transferring the needle seat from the positioning slot to the rotating seat is also provided. The invention can ensure that the direction of the needle seat is consistent during the feeding process of the needle seat, and the feeding process is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of medical accessory assembly machines, and relates to a directional feeding device for needle holders. Background technique [0002] Disposable venous needle products are widely used in clinical practice. Nowadays, the needle holders of domestic venous needles generally adopt single-leaf needle holders, but abroad, the needle holders of intravenous needles widely adopt double-leaf needle holders. [0003] The double-leaf needle hub includes a tubular needle handle and two leaves connected to the outer wall of the needle handle. One end of the needle handle is connected to the catheter, and the other end is connected to the steel needle. The directions of the two cannot be opposite. Therefore, in the automatic assembly process of the venous needle, it is necessary to ensure the accuracy of the orientation of the needle seat during the feeding process of the needle seat, so as to prevent reverse assembly bet...
