[0002] During the processing of blood collection needles, the needles undergo multiple processing links on the production line, including needle molding, coating of a protective layer, and assembly of a protective cap. However, in this process, due to the lack of a suitable device to fix or protect the needle, the needle may be contaminated, damaged or deformed, thus affecting the quality and safety of the product. Therefore, in order to improve the production efficiency and product quality of blood collection needles, a capping device for blood collection needle processing came into being.

[0003] In the traditional blood collection needle processing process, the operator first places the blood collection needle to be processed on a workbench or clamping device to ensure that the needle is in the correct position. The operator then manually installs the protective cap accurately on the tip of the needle, which may involve pushing or rotating the protective cap until it is fully fixed in place.

[0004] However, in the traditional blood collection needle processing process, due to the limited operating speed and accuracy of the operator, the traditional capping operation usually cannot meet the needs of large-scale production, resulting in low production efficiency and difficulty in ensuring that the protective cap of each blood collection needle is correctly installed and fixed. Therefore, a capping device for blood collection needle processing is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 , an embodiment provided by the utility model: a capping device for processing a blood collection needle, comprising a bracket 1, a conveyor belt 2 is arranged on one side of the outer wall of the bracket 1, a cylinder 3 is fixedly connected inside the bracket 1, a slider 4 is fixedly connected to the output end of the cylinder 3, a cylinder 2 5 is fixedly connected inside the slider 4, a lifting block 6 is slidably connected inside the slider 4, the output end of the cylinder 2 5 is fixedly connected to the top of the lifting block 6, a motor 7 is fixedly connected inside the lifting block 6, a spur gear 8 is fixedly connected to the output end of the motor 7, a gear ring 9 is rotatably connected inside the lifting block 6, the spur gear 8 is meshed with the gear ring 9, a fixed block 11 is fixedly connected inside the lifting block 6, a transmission block 10 is rotatably connected inside the fixed block 11, one side of the outer wall of the transmission block 10 is rotatably connected to the inside of the gear ring 9, a clamping block 12 is fixedly connected to one side of the outer wall of the bracket 1, a slider 2 20 is slidably connected to the top of the slider 2 20, and a placement block 19 is fixedly connected to the bottom of the placement block 19. A supporting component is arranged at the bottom of the placement block 19;

[0025] Specifically, when using the capping device for processing blood collection needles, first place the blood collection needle cap on the placement block 19. When the conveyor belt 2 transports the blood collection needle, start the cylinder 2 5, and the cylinder 2 5 pushes the lifting block 6 down. After reaching the blood collection needle position, start the motor 1 7. At this time, the motor 1 7 drives the spur gear 8 to rotate, and then the spur gear 8 drives the gear ring 9 to rotate. Subsequently, through the rotation of the gear ring 9 and the static cooperation of the fixed block 11, the four transmission blocks 10 are driven to rotate, so that the clamping block 12 moves toward the blood collection needle. Through the four clamping blocks 12 In cooperation, the blood collection needle is clamped, and then the cylinder 2 5 is started to lift the lifting block 6, and then the cylinder 1 3 pushes the slider 1 4 to move until it reaches above the blood collection needle cap, and then the cylinder 2 5 is started to push the lifting block 6 down, so that the blood collection needle and the blood collection needle cap are buckled together. The mechanism can automatically clamp the blood collection needle and then buckle it with the blood collection needle cap, avoiding fatigue caused by long-term manual work, resulting in unstable product quality, and the mechanism can also adapt to blood collection needles of different sizes or shapes, providing greater flexibility and applicability.

[0026] Reference Figure 1 - Figure 3 The support assembly includes a slide column 14 and a base 13, the outer wall of the slide column 14 is fixedly connected to the inside of the slider 20, and the top of the base 13 is slidably connected to the bottom of the slider 20;

[0027] Specifically, when the cap-fastening device for processing a blood collection needle is used, when the slider 2 moves, the slide column 14 and the base 13 can stably support the slider 2 20 in the vertical and horizontal directions to ensure the accuracy of the fastening between the blood collection needle and the blood collection cap.

[0028] Reference Figure 1 - Figure 4 The slider 20 is fixedly connected with the motor 2 15, and the output end of the motor 2 15 is fixedly connected with the bevel gear 16. The base 13 is provided with a slide groove 21, and the outer wall of the slide column 14 is slidably connected to the slide groove 21. The slider 20 is rotatably connected with the bevel gear 2 17, and the bevel gear 2 17 is meshed with the bevel gear 16. The bevel gear 2 17 is fixedly connected with the screw rod 18, and the outer wall of the screw rod 18 is threadedly connected to the base 13. The slider 20 is provided with a slide groove 23, and the outer wall of the screw rod 18 is slidably connected to the slide groove 23. The base 13 is provided with a threaded groove 22, and the outer wall of the screw rod 18 is threadedly connected to the threaded groove 22.

[0029] Specifically, when using the cap-fastening device for processing blood collection needles, when the blood collection needle and the blood collection cap need to be calibrated and positioned, first start the motor 2 15, and the motor 2 15 drives the bevel gear 1 16 to rotate, and then the bevel gear 1 16 drives the bevel gear 2 17 to rotate, so that the bevel gear 2 17 drives the screw rod 18 to rotate. When the screw rod 18 rotates, because the screw rod 18 can only rotate relative to the slider 2 20 but not move relative to it, 20 will be forced to move, thereby driving the blood collection needle cap and the blood collection needle to be calibrated and positioned, ensuring that the protective cap is correctly installed on the tip of the blood collection needle, ensuring good cooperation between the blood collection needle and the protective cap, and avoiding displacement or inaccuracy of the installation position.

[0030] Working principle: When using the capping device for processing blood collection needles, first place the blood collection needle cap on the placement block 19, then start the cylinder 2 5, and the cylinder 2 5 pushes the lifting block 6 down. When it reaches directly above the blood collection needle, start the motor 1 7, and the motor 1 7 drives the spur gear 8 to rotate, and then the spur gear 8 drives the gear ring 9 to rotate, and then through the rotation of the gear ring 9, and then through the cooperation with the fixed block 11, the four transmission blocks 10 are driven to rotate, thereby driving the clamping block 12 to gather to the center of the fixed block 11, and then the four clamping blocks 12 clamp the blood collection needle, and then start the cylinder 2 5 to rise. After the rise is completed, start the cylinder 1 3 to push the slider 1 4 to the right Move forward, when it reaches just above the blood collection needle cap, according to the relative position of the blood collection needle cap and the blood collection needle, start the motor 2 15, then the motor 2 15 drives the bevel gear 1 16 to rotate, and then the bevel gear 1 16 drives the bevel gear 2 17 to rotate, and then the bevel gear 2 17 drives the screw rod 18 to rotate. Because the screw rod 18 and the slider 2 20 will not have relative displacement, when the screw rod 18 rotates, the slider 2 20 will be displaced by force, and then the slider 2 20 drives the placement block 19 to move, so that the blood collection needle and the blood collection needle cap are in the same vertical line, and finally start the cylinder 2 5 to push the lifting block 6 down, and the blood collection needle and the blood collection needle cap can be buckled.
