[0026] In one embodiment of the present utility model, as Figures 1 to 4 shown, a blood collection needle automatic needle arranging device is provided, which includes a mounting plate 10, a needle arranging and placing rail 20, a needle bin 30, and a needle arranging lead screw module 40. The needle arranging and placing rail 20 is horizontally installed and fixed on the mounting plate 10. A plurality of needle slots 21 arranged at intervals are provided on the needle arranging and placing rail 20. The needle bin 30 is used for containing blood collection needles. The needle bin 30 is arranged above the needle arranging and placing rail 20. An outlet hole close to the needle arranging and placing rail 20 is provided at the bottom of the needle bin 30. Among them, the outlet hole provided at the bottom of the needle bin 30 close to the needle arranging and placing rail 20 means that there is a sufficient gap between the bottom of the needle bin 30 and the needle arranging and placing rail 20 to enable relative sliding between the two. The needle arranging lead screw module 40 is installed on the mounting plate 10. The needle arranging lead screw module 40 is connected to the needle bin 30 and drives the needle bin 30 to translate along the needle arranging and placing rail 20. When the outlet hole moves to be directly opposite the needle slot 21, the blood collection needle in the needle bin 30 drops and is placed in the needle slot 21.
[0027] For the blood collection needle automatic needle arranging device in the embodiments of the present utility model, the needle arranging lead screw module 40 drives the connected needle bin 30 to translate along the extending direction of the needle arranging and placing rail 20. Since a plurality of needle slots 21 arranged at intervals are provided on the needle arranging and placing rail 20, and an outlet hole close to the needle arranging and placing rail 20 is provided at the bottom of the needle bin 30. In this way, when the outlet hole of the needle bin 30 moves above the needle slot 21 of the needle arranging and placing rail 20, a blood collection needle in the needle bin 30 will drop into the needle slot 21. As the needle bin 30 continues to be driven by the needle arranging lead screw module 40, the blood collection needles in the needle bin 30 are dropped one by one and placed in the plurality of needle slots 21 arranged at intervals on the needle arranging and placing rail 20, realizing the orderly, efficient, and accurate arrangement of blood collection needles in the needle slots 21 of the needle placing rail. In subsequent processes, a plurality of blood collection needles located in the needle slots 21 of the needle arranging and placing rail 20 can be sucked at one time by a vacuum adsorption plate.
[0028] In one embodiment of the present utility model, as Figure 4As shown, vacuum adsorption holes 22 communicating with each of the needle head grooves 21 are provided at the bottom of the needle placement rail 20. Specifically, the vacuum adsorption holes 22 can be externally connected to a vacuum generator. By evacuating the air, the blood collection needles arranged in the needle head grooves 21 of the needle placement rail 20 can be stably adsorbed, so as to prevent the blood collection needles located in the needle head grooves 21 from being ejected due to vibration, ensuring the stability of needle placement.
[0029] In an embodiment of the present utility model, as Figures 1 to 2 shown, needle-taking positioning blocks 50 are provided on opposite sides of the needle placement rail 20 on the mounting plate 10, and needle-taking positioning holes 51 are provided on the needle-taking positioning blocks 50. Specifically, by making evidence-taking positioning holes on the provided needle-taking positioning blocks 50, they can cooperate with the evidence-taking positioning posts on the vacuum adsorption plate that sucks the blood collection needles in the needle head grooves 21 of the needle placement rail 20, so as to accurately adsorb and take the blood collection needles in the needle head grooves 21 of the needle placement rail 20.
[0030] In an embodiment of the present utility model, as Figures 1 to 2 shown, the needle placement lead screw module 40 includes a motor 41, a lead screw 42, a nut 43, a connecting block 44, two guide rails 45 and two sliders 46. The two guide rails 45 are arranged on both sides of the lead screw 42 and are parallel to the needle placement rail 20. The two guide rails 45 are fixedly connected to the mounting plate 10. The lead screw 42 is rotatably installed on the mounting plate 10 and one end thereof is connected to the motor 41. The nut 43 is threadedly connected to the lead screw 42. The two sliders 46 are respectively slidably connected to the two guide rails 45. The connecting block 44 is respectively connected and fixed to the nut 43 and the two sliders 46. The needle head bin 30 is connected and fixed to the connecting block 44. Specifically, the motor 41 drives the lead screw 42 to rotate, driving the nut 43 to move along the lead screw, so as to drive the needle head bin 30 to translate on the needle placement rail 20 through the connecting block 44 with the sliding of the two sliders 46 on the two guide rails 45 as the guide, thereby realizing needle placement of the blood collection needles in the needle placement rail 20.
[0031] In an embodiment of the present utility model, as Figures 1 to 2 shown, a plurality of spaced-apart support plates 60 are provided at the bottom of the mounting plate 10. Specifically, the provision of the support plates 60 can facilitate the installation of the entire device at a relatively high position, facilitating cooperation with adjacent other automated devices.
[0032] Preferably, three support plates 60 are provided.
[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
