The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0020] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, a blood collection needle feeding mechanism for a capillary blood collection needle cartoning machine is used to be installed on the capillary blood collection needle cartoning machine. The capillary blood collection needle cartoning machine includes a machine base 100, on which a feeding conveyor belt 200 is provided.

[0023] The blood collection needle feeding mechanism includes a feeding component 1, a detection component 2, and a picking component 3, which are respectively connected to the machine base 100.

[0024] The feeding component 1 is used to receive the blood collection needles to be boxed and can sequentially transport the blood collection needles to the gripping position of the picking component 3. During processing, the blood collection needles are transported to the feeding component 1 by a feeding machine or manually, and then the blood collection needles are sequentially transported to the gripping position of the picking component 3 by the feeding component 1.

[0025] The detection component 2 is set at the corresponding position of the feeding component 1 and is used to take pictures of the blood collection needle on the feeding component 1 to obtain the direction of the blood collection needle on the feeding component 1.

[0026] The picking component 3 is connected to the feeding component 1 and the feeding conveyor belt 200 respectively. It is used to pick up the blood collection needles from the feeding component 1 and place them on the feeding conveyor belt 200. The picking component 3 is equipped with a turning mechanism, which is used to drive the blood collection needles to turn in the same direction, so that the picking component 3 places all the blood collection needles on the feeding conveyor belt 200 in the same direction, ensuring that the feeding direction is consistent.

[0027] During processing, blood collection needles are fed onto the feeding assembly 1 via a feeding machine or manually. The feeding assembly 1 then sequentially feeds the blood collection needles to the gripping position of the picking assembly 3. While the feeding assembly 1 feeds the blood collection needles to the picking assembly 3, the detection assembly 2 takes pictures of each blood collection needle on the feeding assembly 1. After the feeding assembly 1 feeds the blood collection needles to the gripping position of the picking assembly 3, the picking assembly 3 picks up each blood collection needle from the feeding assembly 1. Based on the images of the blood collection needles taken by the detection assembly 2, it determines whether the direction of the current blood collection needle is consistent with the feeding direction. If they are inconsistent, the picking mechanism drives the blood collection needles to change direction. When the direction of all the blood collection needles picked up by the picking assembly 3 is consistent with the feeding direction, the picking assembly 3 places the blood collection needles onto the feeding conveyor belt 200, which then transports the blood collection needles to the downstream processing station, completing the feeding process of the blood collection needles.

[0028] like Figure 3As shown, the feeding assembly 1 includes a receiving box 11 and a direct vibration module 12, which are respectively connected to the machine base 100. The output end of the direct vibration module 12 is equipped with a feeding guide rail 13, one end of which extends into the receiving box 11, and the other end is connected to the picking assembly 3. The feeding guide rail 13 is equipped with a guide groove 14 for accommodating and guiding the blood collection needles. During operation, the feeding machine or a person pours the blood collection needles into the receiving box 11. The blood collection needles automatically fall into the guide groove 14 on the feeding guide rail 13, and then the direct vibration module 12 drives the blood collection needles to move forward within the guide groove 14, thereby conveying the blood collection needles to the gripping position of the picking assembly 3.

[0029] To ensure the blood collection needles in the receiving box 11 fall smoothly into the guide trough 14, in this embodiment, a guide motor 15 is provided on the receiving box 11. A rotating shaft 16 is connected to the output end of the guide motor 15, extending into the receiving box 11 and rotatably connected to it. A guide blade 17 is provided on the rotating shaft 16, which pushes the blood collection needles into the guide trough 14. The guide blade 17 can be made of flexible materials such as silicone to avoid damaging the blood collection needles. After the blood collection needles are tilted into the receiving box 11, the guide motor 15 starts working, driving the rotating shaft 16 and the guide blade 17 to rotate. The guide blade 17 pushes the blood collection needles in the receiving box 11, causing them to fall into the guide trough 14. Then, in conjunction with the direct vibration module 12, the blood collection needles are transported to the gripping position of the picking component 3.

[0030] The direct vibration module 12 can be any existing type, and this utility model does not limit it.

[0031] Preferably, there are two vertical vibration modules 12 and two feeding guide rails 13, and each feeding guide rail 13 is provided with five feeding grooves 14. This design can process ten blood collection needles at the same time, greatly improving the feeding efficiency.

[0032] like Figure 4As shown, the detection component 2 includes a detection mounting frame 21, which is connected to the machine base 100. The detection mounting frame 21 is equipped with a detection camera 22 and a supplementary light source 23, both located above the feeding guide rail 13. The detection camera 22 is used to photograph the blood collection needles in the feeding trough 14, and the supplementary light source 23 is used to illuminate the blood collection needles in the feeding guide rail 13 so that the detection camera 22 can obtain a clear image. During operation, the linear vibration module 12 operates, driving the blood collection needles to move linearly on the feeding guide rail 13. When the blood collection needle moves below the detection camera 22, the supplementary light source 23 illuminates the blood collection needles on the feeding guide rail 13, and the detection camera 22 then photographs the blood collection needles, thereby obtaining a clear image of the blood collection needles in the feeding trough 14. The image is then transmitted to the control center of the terminal blood collection needle cartoning machine. The control center can determine whether the direction of the blood collection needles in the feeding trough 14 is consistent with the preset feeding direction by comparison.

[0033] In this embodiment, there are two detection cameras 22 and two supplementary lighting sources 23, and they are configured in a one-to-one correspondence. By setting two detection cameras 22, the blood collection needles in the ten guide slots 14 on the two feeding guide rails 13 can be detected simultaneously, improving efficiency.

[0034] like Figure 5 As shown, the material handling assembly 3 includes a material handling fixing frame 31, which is connected to the machine base 100. A material handling transverse movement module 32 is mounted on the material handling fixing frame 31, and a material handling lifting module 33 is mounted on the output end of the material handling transverse movement module 32. Both the material handling transverse movement module 32 and the material handling lifting module 33 can employ any existing linear drive device, such as a cylinder module, an electric cylinder module, or a motor lead screw module; the specific structure is not limited in this invention. A steering mechanism is connected to the output end of the material handling lifting module 33, and a material handling gripper cylinder 34 is mounted on the output end of the steering mechanism. During operation, the material handling transverse module 32 and the material handling lifting module 33 work together to drive the material handling gripper cylinder 34 to the end of the loading guide rail 13, whereby the material handling gripper cylinder 34 picks up the blood collection needle from the loading guide rail 13. Then, through the cooperation of the material handling transverse module 32 and the material handling lifting module 33, the material handling gripper cylinder 34 moves to the loading position of the feeding conveyor belt 200, whereby the material handling gripper cylinder 34 releases the blood collection needle. This process transfers the blood collection needle from the loading guide rail 13 to the feeding conveyor belt 200.

[0035] Specifically, the steering mechanism includes a rotary cylinder 35, which is connected to the output end of the material handling and lifting module 33, and a material handling gripper cylinder 34 is connected to the output end of the rotary cylinder 35. During processing, if the detection camera 22 captures images of a blood collection needle in a certain guide groove 14 with the opposite direction, the material handling gripper cylinder 34 picks up the blood collection needle and then controls the corresponding rotary cylinder 35 to work, driving the material handling gripper cylinder 34 to rotate the blood collection needle 180°, thereby reversing the direction of the blood collection needle and achieving the purpose of turning the feeding direction of the blood collection needle.

[0036] In addition, such as Figure 1 , Figure 6 As shown, the machine 100 is also equipped with a material shortage detection mechanism 4, which is located between the receiving box 11 and the material picking component 3. It is used to detect whether there is a blood collection needle in the guide trough 14. By setting up the material shortage detection mechanism 4, it is possible to monitor whether there is a blood collection needle in the guide trough 14 in real time, avoid the phenomenon of empty grabbing, and improve the stability and reliability of the feeding process.

[0037] Specifically, the material shortage detection mechanism 4 includes a material shortage mounting frame 41, which is connected to the machine base 100. The mounting frame 41 is equipped with a mounting rod 42, positioned above the feeding guide rail 13. Material shortage sensors 43 are respectively installed on the mounting rod 42 at corresponding positions to the guide trough 14. The material shortage sensors 43 can detect in real time whether there are blood collection needles in the corresponding guide trough 14. If a material shortage sensor 43 detects that there is no product in the guide trough 14, it sends a feedback signal to remind the operator to replenish the blood collection needles in the receiving box 11 in a timely manner, avoiding idle operation and improving equipment utilization.

[0038] Working principle: During the processing, the blood collection needles are first fed into the receiving box 11 by a feeding machine or manually. Then, the guide motor 15 operates, driving the rotating shaft 16 and the guide blades 17 to rotate, pushing the blood collection needles into the guide grooves 14 of each feeding guide rail 13. Then, the direct vibration module 12 is controlled to operate, conveying the blood collection needles forward along the feeding guide rail 13.

[0039] When the lancet passes under the detection component 2, the detection camera 22 takes a picture of the lancet with the assistance of the supplementary light source 23 to obtain the lancet's orientation information.

[0040] After the lancet is delivered to the gripping position of the material handling assembly 3, the material handling transverse module 32 and the material handling lifting module 33 work together to drive the material handling gripper cylinder 34 to move to the gripping position at the end of the feeding guide rail 13. The material handling gripper cylinder 34 then grips the lancet from the guide groove 14. After the material handling gripper cylinder 34 grips the lancet, the direction of the lancet is determined based on the image captured by the detection camera 22. If the direction of the lancet is opposite to the preset direction, the corresponding rotary cylinder 35 is controlled to work, driving the material handling gripper cylinder 34 to rotate the lancet 180°.

[0041] Once all the gripping needles held by the gripping cylinders 34 are aligned, the lateral movement module 32 and the lifting module 33 work together again to move the needles above the feeding conveyor belt 200. The gripping cylinders 34 then release, placing the needles onto the feeding conveyor belt 200. The feeding conveyor belt 200 then transports the needles to the downstream cartoning station, completing the needle loading process.

[0042] Throughout the process, the material shortage detection mechanism 4 monitors in real time whether there are blood collection needles in the feed trough 14. If there is a material shortage, the system will promptly sound an alarm to remind the operator to replenish the blood collection needles in time, ensuring the continuity and stability of the feeding process.

[0043] This invention achieves automatic feeding, direction detection, and direction adjustment of blood collection needles through the coordinated operation of the feeding component 1, the detection component 2, and the picking component 3, ensuring that all blood collection needles are transported to the boxing station in a uniform direction, which greatly improves boxing efficiency and product consistency.

[0044] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
