Therefore, a winding mechanism for blood collection needles is proposed. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] See Figure 1-5A winding mechanism for a blood collection needle includes a support frame 1, a transmission frame 6 mounted on the support frame 1, a clamping assembly 2 slidably connected to the transmission frame 6, a rotating assembly 3 located below the support frame 1, a winding assembly 4 connected to the rotating assembly 3, the winding assembly 4 including a connecting frame 41, a transverse plate 43 slidably connected to the connecting frame 41, multiple stop bars 431 mounted on the transverse plate 43, a second cylinder 44 connected to the transverse plate 43, the second cylinder 44 being fixedly connected to the connecting frame 41, a winding component 45 mounted on the rotating assembly 3, the winding component 45 including a base 451, a moving block 454 slidably connected to the base 451, a push plate 455 mounted on the moving block 454, a winding rod 452 mounted on the base 451, and a moving rod 453 slidably connected to the winding rod 452. In use, the operator or the intelligent program controls an external robotic arm to place multiple blood collection needles 5 onto the clamping assembly 2 and winding assembly 4 of the device. The intelligent program is existing technology and will not be described in detail here. The clamping assembly 2 and the winding component 45 work together to support the blood collection needles 5. Then, the rotating assembly 3 is controlled to drive the winding assembly 4 to work. The rotating assembly 3 is an existing rotator, which serves to rotate multiple bases 451 and will not be described in detail here. Taking one of the winding components 45 as an example, before winding, the second cylinder 44 is controlled to push the transverse plate 43 to move. The transverse plate 43 drives the stop rod 431 to move. The lever 453 moves to facilitate the placement of the blood collection needle 5 by the robotic arm. Then, the rotating component 3 drives the base 451 to rotate, and the base 451 drives the winding component 45 to rotate. The winding component 45 then begins to wind the blood collection needle 5. As the blood collection needle 5 is wound, the clamping component 2 gradually moves closer to the winding component 4 under the drive of the transfer frame 6 until all the blood collection needle 5 is wound. The other winding components 45 are wound in the same way, thus completing the winding of multiple blood collection needles 5. This is convenient, fast, and fully automated, eliminating the need for manual winding, reducing labor costs, eliminating the influence of human factors, increasing winding speed, and accelerating production progress.

[0013] In some embodiments, a first cylinder 42 is mounted on the side of the connecting frame 41, and a push plate 455 is slidably connected to a winding rod 452. After winding is completed, the operator or intelligent control program controls the rotating assembly 3 to rotate the push plate 455 to the front of the first cylinder 42, and then controls the first cylinder 42 to extend and push the push plate 455. The push plate 455 moves closer to the winding rod 452 via the moving block 454, so that a certain range is left in the middle of the wound blood collection needle 5, which is convenient for the robot arm to grip and package the wound blood collection needle 5, thereby improving production efficiency.

[0014] In some embodiments, the clamping assembly 2 includes an electric push rod 21, a support frame 23 is mounted on the telescopic part of the electric push rod 21, a support plate 11 is slidably connected to the support frame 1, a slider 22 is slidably connected between the support plate 11 and the support frame 23, a plurality of clamping members 24 are provided on the support frame 23, the clamping member 24 includes a sliding block 241, a transverse cylinder 242 is mounted on the sliding block 241, and a clamp 243 is provided on the transverse cylinder 242 to clamp the blood collection needle 5. After the robotic arm moves multiple blood collection needles 5, taking one of the clamps 243 as an example, the operator or intelligent control program controls the horizontal cylinder 242 to open the clamp 243, which works in conjunction with the winding rod 452 and the moving rod 453 to clamp the blood collection needle 5. Then, the winding assembly 4 is controlled to start winding the blood collection needle 5. During winding, the electric push rod 21 is controlled to continuously extend and retract, causing the electric push rod 21 to drive the support frame 23 to move left and right on the support plate 11. With the assistance of the slider 22, the end of the clamp 243 holding the blood collection needle 5 follows the winding of the other end of the blood collection needle 5 in a near-circular motion, which facilitates the winding of the blood collection needle 5, prevents the blood collection needle 5 from being taut and damaged, improves the winding speed, and ensures the quality of the blood collection needle 5.

[0015] In some embodiments, a protective frame 25 is provided on the support frame 23. The protective frame 25 not only protects the clamping member 24 from being bumped or affected by external factors, but also supports the blood collection needle 5 to prevent the end of the blood collection needle 5 from drooping down, which would cause resistance during winding and affect the winding speed. In some embodiments, a spring 26 is provided on each side of the support plate 11 at the connection between the support frame 23 and the electric push rod 21. When the support frame 23 is driven by the electric push rod 21 to move left and right, the spring 26 can ensure that the support frame 23 moves left and right with a small amplitude, so that the movement of the clamping component 2 is not large when the blood collection needle 5 is wound, ensuring the smoothness of the winding and improving the winding speed.

[0016] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
