Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulin needle processing device, and particularly relates to an insulin needle supplying device. BACKGROUND

[0002] In the process of insulin needle production, there is a very important step, that is, inserting the needle into the needle seat. In the early stage of insulin needle production, due to the limitation of technology, the manual insertion method is usually used. Although the manual insertion method can realize the assembly of the needle and the needle seat, in the process of insertion, the staff directly takes the needle from the needle box by hand or tweezers. Since the needles are stacked in the needle box one by one, when the needle is taken by hand or tweezers, the fingers or tweezers will push away the needles beside the target needle, which is easy to make the needles disorder, and is not conducive to the subsequent continuous taking of the needles. At the same time, since the needle is thin, the hand will mistakenly grab multiple needles at a time, so the extra needles need to be put back, which is not convenient for direct use.

[0003] Therefore, the current method of directly taking the needle from the needle box by hand is cumbersome and inconvenient, and therefore needs to be solved. SUMMARY

[0004] In order to avoid and overcome the technical problems existing in the prior art, the present application provides an insulin needle supplying device. The present application can effectively improve the convenience of needle grabbing.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0006] An insulin needle supplying device comprises a needle box mounted on a support frame for storing needles, and each horizontally placed needle is stacked side by side in the needle box from top to bottom. A rectangular needle falling hole for the vertical falling of the needle is formed at the bottom of the needle box, and the hole length direction of the needle falling hole is parallel to the length direction of the needle in the needle box. A needle taking disc is rotatably installed below the needle falling hole, and the rotation axis of the needle taking disc is parallel to the length direction of the needle in the needle box. The outer circumferential surface of the rotating needle taking disc is attached to the hole opening of the needle falling hole to block the needle in the needle falling hole. A needle storage groove capable of accommodating only one needle at a time is formed on the outer circumferential surface of the needle taking disc, and the groove length direction of the needle storage groove is parallel to the length direction of the needle in the needle box. The needle storage groove is provided with a magnetic element capable of magnetically attracting the needle in the needle storage groove, and the tail of the needle is exposed outside the needle storage groove.

[0007] As a further scheme of the present application, guide grooves extending in the vertical direction are formed on both sides of the needle box, and a pressing rod pressing on the needle is inserted in the two guide grooves.

[0008] As a further scheme of the present application: the pressing rod is cylindrical, and a rotating gap is left between the pressing rod and the guide groove; a plurality of annular grooves with a groove depth smaller than the radius of the needle are recessed in the pressing rod in a coaxial manner, and the annular grooves are arranged in sequence along the axial direction of the pressing rod.

[0009] As a further scheme of the present application: the two ends of the pressing rod are both provided with a counterweight, the counterweight is a hollow cylinder and is arranged coaxially with the pressing rod; a cylindrical rolling cavity is formed coaxially in the inside of the counterweight, and a plurality of rolling balls are placed in the rolling cavity.

[0010] As a further scheme of the present application: a plurality of protrusions that can collide with the rolling balls and make the rolling balls jump up are arranged on the inner wall surface of the rolling cavity, and a passage for the rolling balls to pass through is formed between adjacent protrusions.

[0011] As a further scheme of the present application: positioning holes are formed on both sides of the needle falling hole of the needle box, and a blocking pin is inserted into the positioning holes to block the needle falling hole and prevent the needle from falling.

[0012] As a further scheme of the present application: the blocking pin is in the shape of a U-shaped clamp.

[0013] As a further scheme of the present application: the box cavity of the needle box is a tapered needle storage space that gradually shrinks from top to bottom.

[0014] As a further scheme of the present application: a plurality of needle storage grooves are formed on the outer circumferential surface of the needle taking disc, and the needle storage grooves are uniformly arranged in the circumferential direction of the needle taking disc.

[0015] As a further scheme of the present application: the magnetic member is an electromagnet installed inside the needle taking disc.

[0016] 1、The needle supply part adopts a needle box installed on the support frame to orderly store the needles, each needle is horizontally placed and stacked in sequence, such a design not only saves space, but also improves the stability and accessibility of the needles.

[0017] 3、The guide grooves opened on both sides of the needle box and the inserted pressure rod can further improve the stability of the needle and the convenience of taking. The pressure rod is pressed on the needle, balanced by the counterweight blocks at both ends, and a rotating gap is left between the pressure rod and the guide groove, so that the pressure rod can slightly rotate when subjected to external force, thereby more flexibly adapting to needles of different sizes. The multiple annular grooves coaxially recessed on the pressure rod provide convenience for embedding the uppermost row of needles in the needle box. The pressure rod is pressed on the middle of the needle in the needle box, and the uppermost row of needles is embedded in the annular groove, which can keep it stable and avoid dislocation caused by vibration during processing, making the needle taking process smoother.

[0018] 4、The rolling cavity and the ball design inside the counterweight block not only reduce the weight of the counterweight block, but also increase the downward tendency of the pressure rod through the collision and lifting of the ball and the protrusion, avoiding the situation that the needle in the needle box is stuck due to accumulation and cannot fall, improving the stability and flexibility during the needle taking process. This design not only improves the assembly efficiency, but also ensures the safety and reliability of the entire assembly process.

[0019] 5、When the device vibrates during operation, due to the gap fit between the pressure rod and the guide hole, combined with the small rolling between the annular groove and the needle, the ball will roll between the protrusions in the rolling cavity; the slightly convex protrusions will lift the passing ball, then fall down and collide with the counterweight block, thereby providing an intermittent repetitive downward vibration force for the pressure rod to regularly push the needles towards the falling hole, avoiding the situation that the needles on the lower side of the needle box are stuck with the needles on the upper side due to accumulation, improving the continuity of the feeding.

A disc-shaped needle taking disc 22 is rotatably installed below the needle falling hole 212, and the rotation axis of the needle taking disc 22 is parallel to the length direction of the needle heads a in the needle box 21. The outer circumferential surface of the rotating needle taking disc 22 is attached to the hole opening of the needle falling hole 212 to block the needle heads a in the needle falling hole 212, and then a needle storage groove 221 capable of accommodating only one needle head a is formed on the outer circumferential surface of the needle taking disc 22, and the groove length direction of the needle storage groove 221 is parallel to the length direction of the needle heads a in the needle box 21. The needle storage groove 221 is provided with a magnetic member capable of magnetically attracting the needle heads a in the needle storage groove 221, and the tail of the needle head a is exposed outside the needle storage groove 221, so that when the needle taking disc 22 rotates under the driving of a servo motor, one needle head a falls into the needle storage groove 221 through the needle falling hole 212, and the tail of the needle head a is exposed outside the needle storage groove 221, which is convenient for the tweezers to pick up. Under the magnetic attraction of the electromagnet as the magnetic part, the needle head a rotates 180 degrees to the lowermost needle taking position of the needle taking disc 22 with the needle storage groove 221 rotating away from the needle falling hole, for subsequent use.

[0028] Positioning holes 213 are formed on both sides of the needle falling hole 212 of the needle box 21, and U-shaped clamping-shaped blocking pins 25 are inserted into the positioning holes 213 to block the needle falling hole 212 to avoid the needle heads a from falling, so as to block the needle heads a when the needle taking disc 22 is replaced.
