Description

Technical Field

[0001] The invention relates to the technical field of insulin needle processing devices, in particular to an insulin needle supply device. Background Art

[0002] In the process of insulin needle production, a very important step is involved, which is to plug the needle into the needle holder. In the early stage of insulin needle production, due to technical limitations, manual plugging is usually used. Although the assembly of the needle and the needle holder can be achieved through manual plugging, during the plugging process, employees use their hands or tweezers to directly pick up the needle from the needle box. Since the needles are stacked up and down in the needle box in sequence, when using hands to pick up the needles, the fingers or tweezers will squeeze out other needles beside the target needle, which can easily cause the needles to be disordered and is not conducive to the subsequent continuous clamping of the needles. At the same time, because the needles are thin, if you use your hands directly, you will accidentally grab multiple needles at one time, so the extra needles need to be put back, which is not convenient for direct use.

[0003] It can be seen that the current method of manually clamping the needle directly from the needle box is relatively cumbersome and inconvenient, so it is urgent to solve the problem. Summary of the invention

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

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An insulin needle supply device comprises a needle box installed on a support frame for storing needles, wherein horizontally placed needles are stacked side by side in the needle box from top to bottom; a rectangular needle drop hole for vertically dropping needles is provided at the bottom of the needle box, and the length direction of the needle drop hole is parallel to the length direction of the needles in the needle box; a needle retrieval disk is rotatably installed below the needle drop hole, and the rotation axis of the needle retrieval disk is parallel to the length direction of the needles in the needle box; the outer circumferential surface of the rotating needle retrieval disk is fitted at the orifice of the needle drop hole to block the needle in the needle drop hole, and a needle storage groove which can only accommodate one needle at a time is provided on the outer circumferential surface of the needle retrieval disk, 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 member which can magnetically adsorb the needle in the needle storage groove, and the tail of the needle is exposed outside the needle storage groove.

[0007] As a further solution of the present invention: guide grooves extending in the vertical direction are provided on both sides of the needle box, and pressure rods pressing on the needle heads are inserted into the two guide grooves at the same time.

[0008] As a further solution of the present invention: the pressure rod is cylindrical and has a rotation gap between it and the guide groove; the rod body of the pressure rod is coaxially concave with multiple annular grooves with a depth smaller than the radius of the needle and used to embed the top row of needles in the needle box, and the annular grooves are arranged in sequence along the axial direction of the pressure rod.

[0009] As a further solution of the present invention: counterweight blocks are installed at both ends of the pressure rod. The counterweight blocks are hollow cylinders and are coaxially arranged with the pressure rod. A cylindrical rolling cavity is coaxially formed inside the counterweight block, and a plurality of balls are placed in the rolling cavity.

[0010] As a further solution of the present invention: a plurality of protrusions are arranged on the inner wall surface of the rolling cavity, which can collide with the balls and lift the balls, and channels for the balls to pass through are formed between adjacent protrusions.

[0011] As a further solution of the present invention: positioning holes are provided on both sides of the needle drop hole on the needle box, and blocking pins are inserted into the positioning holes to block the needle drop hole to prevent the needle from falling.

[0012] As a further solution of the present invention: the retaining pin is in a U-shaped card shape.

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

[0014] As a further solution of the present invention: a plurality of needle storage grooves are provided on the outer circumferential surface of the needle removal disk, and the needle storage grooves are evenly arranged along the circumference of the needle removal disk.

[0015] As a further solution of the present invention: the magnetic member is an electromagnet installed inside the needle removal disk. Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The needle supply part of the present invention adopts a needle box installed on a support frame to store needles in order. Each needle is placed horizontally and stacked side by side in sequence. Such a design not only saves space, but also improves the stability and accessibility of the needles. More cleverly, a rectangular needle drop hole is designed at the bottom of the needle box, and its length direction is parallel to the length direction of the needle, ensuring the stability and accuracy of the needle when it falls vertically. In addition, the needle supply part is also equipped with a rotary needle retrieval tray, and its rotation axis is consistent with the length direction of the needle. Such a design enables the needle retrieval tray to effectively block the needle in the needle drop hole when the outer circumferential surface fits the orifice of the needle drop hole, thereby avoiding the accidental drop of the needle. The needle storage slot design on the needle retrieval tray is even more ingenious, and can only accommodate one needle at a time, ensuring the accuracy and consistency of needle retrieval. At the same time, a magnetic piece is also equipped in the needle storage slot, which can magnetically adsorb the needle so that the tail of the needle is exposed outside the needle storage slot, which is convenient for needle retrieval and ensures the stability and safety of the needle.

[0017] 3. The guide grooves and inserted pressure rods on both sides of the needle box can further improve the stability of the needles and the convenience of taking them. The pressure rod presses on the needles and maintains balance through the counterweights at both ends. At the same time, a rotation gap is left between the pressure rod and the guide groove, so that the pressure rod can rotate slightly when subjected to external force, thereby more flexibly adapting to needles of different sizes. The design of multiple coaxially concave annular grooves on the pressure rod body provides convenience for embedding the top row of needles in the needle box. The pressure rod presses on the middle of the needles in the needle box, and the top row of needles are embedded in the annular grooves, which can maintain its stability and avoid the shaking and dislocation of the needles due to the vibration of the device during the processing, making the needle removal process smoother.

[0018] 4. The rolling cavity and ball design inside the counterweight not only reduces the weight of the counterweight, but also increases the downward pressure of the pressure rod through the collision and lifting of the ball and the protrusion, avoiding the situation where the needles inside the needle box are stuck due to backlog and cannot fall, and improving the stability and flexibility during the needle removal 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 equipment vibrates during operation, the clearance between the pressure rod and the guide hole, as well as the small rolling motion between the annular groove and the needle, causes the ball to roll between the protrusions in the rolling cavity; at the same time, the slightly raised protrusions cause the balls passing through them to be lifted up, and then fall down and collide with the counterweight, thereby providing an intermittent and repetitive downward vibration force for the pressure rod, so as to regularly push the needles to gather at the drop hole, avoiding the needles on the lower side of the needle box from being piled up with the needles on the upper side and getting stuck to each other, thereby improving the continuity of the feeding.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 to Figure 5 In an embodiment of the present invention, an insulin needle supply device includes a needle box 21 mounted on a support frame 11 for storing needles a. The box cavity of the needle box 21 is a needle storage space that is larger at the top and smaller at the bottom, and the thickness of the needle storage space is slightly larger than the length of the needle a to prevent the needle a from getting stuck in the needle box 21, so that each horizontally placed needle a is stacked side by side from top to bottom in the needle box 21. A rectangular needle drop hole 212 is provided at the bottom of the needle box 21 for the needle a to drop vertically, and the length direction of the needle drop hole 212 is parallel to the length direction of the needle a in the needle box 21. A disc-shaped needle removal disk 22 is rotatably installed below the needle drop hole 212, and the rotation axis of the needle removal disk 22 is parallel to the length direction of the needle a in the needle box 21. The outer circumferential surface of the rotating needle retrieval disk 22 fits against the opening of the needle drop hole 212 to block the needle a in the needle drop hole 212, and then a needle storage groove 221 that can only accommodate one needle a at a time is opened on the outer circumferential surface of the needle retrieval disk 22, and the groove length direction of the needle storage groove 221 is parallel to the length direction of the needle a in the needle box 21; the needle storage groove 221 is arranged with a magnetic part that can magnetically adsorb the needle a in the needle storage groove 221, and the tail of the needle a is exposed outside the needle storage groove 221, so that when the needle retrieval disk 22 is driven by the servo motor to rotate, the needle storage groove 221 passes through the needle drop hole 212, and one of the needles a falls into the needle storage groove 221, and the tail of the needle a is exposed outside the needle storage groove 221, which is convenient for clamping with tweezers. The needle a is attracted by the electromagnet as the magnetic part, and rotates away from the blanking hole along with the needle storage slot 221, and rotates 180 degrees to the lowest needle removal position of the needle removal disk 22 for subsequent use.

[0028] Positioning holes 213 are provided on both sides of the needle hole 212 on the needle box 21. A U-shaped blocking pin 25 is inserted into the positioning hole 213 to block the needle hole 212 to prevent the needle a from falling, so as to block the needle a when replacing the needle tray 22.

[0029] As the needle a is continuously taken away by the needle tray 22, the needle a in the needle box 21 gradually sinks. In order to further improve the stability of the sinking, guide grooves 211 extending in the vertical direction are provided on both sides of the needle box 21. Pressure rods 23 are inserted in the two guide grooves 211 at the same time. The pressure rods 23 press on the needle a, and counterweights 24 are installed at both ends of the pressure rods 23. The pressure rod 23 is cylindrical, and there is a rotation gap between it and the guide grooves 211; the rod body of the pressure rod 23 is coaxially concave with multiple annular grooves 231 with a groove depth less than the radius of the needle a and used to embed the needle a in the uppermost row of the needle box 21, and each annular groove 231 is arranged in sequence along the axial direction of the pressure rod 23. The pressure rod 23 is pressed on the middle of the needle a in the needle box 21, and the needle a in the uppermost row is embedded in the annular groove 231, which can keep it stable and avoid the needle a shaking and misalignment due to the vibration of the device during the processing, making the needle removal process smoother. The needle can also be removed from the needle tray 22 by vacuum adsorption. That is, a small vacuum pump is arranged in the needle tray 22, and the vacuum pump is connected to the suction hole at the bottom of the needle storage groove 221, so that the needle a is adsorbed in the needle storage groove 221.

[0030] The counterweight block 24 is a hollow cylinder and is arranged coaxially with the pressure rod 23; a cylindrical rolling cavity is coaxially formed inside the counterweight block 24, and a plurality of balls 242 are placed in the rolling cavity. A plurality of protrusions 241 that can collide with and lift the balls 242 are arranged on the inner wall surface of the rolling cavity, and a passage for the balls 242 to pass through is formed between adjacent protrusions 241. The design of the rolling cavity and the balls 242 arranged inside the counterweight block 24 not only reduces the weight of the counterweight block 24, but also, when the entire device is running, the balls 242 will collide and lift with the protrusions 241 during the rolling process due to vibration, thereby increasing the downward pressure trend of the pressure rod 23, avoiding the situation in which the needle a cannot fall due to the backlog of needles a stuck inside the needle box 21, and improving the stability during the needle removal process.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
