[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 In this embodiment of the invention, a fully automatic screening workstation for vacuum blood collection tube protective caps includes a base 1. A bottom support 8 is fixedly connected to one side of the upper surface of the base 1. A UV module support 7 is installed on one side of the bottom support 8. The UV module support 7 is provided with a conveying assembly for conveying the protective caps. The conveying assembly includes top pulleys 9. Two top pulleys 9 are installed on both sides of the upper end of the UV module support 7. A first motor 12 is installed on one side of the bottom of the UV module support 7. A bottom pulley 13 is rotatably connected to the bottom of the UV module support 7. The bottom pulley 13 and the first motor 12 are driven by a belt. A toothed belt 11 is installed between the two top pulleys 9 and the bottom pulley 13. Cap diameter dampers 10 are provided on both sides of the toothed belt 11 on the upper end of the UV module support 7 near the protective cap loading container 6. The UV module support 7 is inclined. During operation, the first motor 12 drives the bottom pulley 13 to rotate, and the rotation of the bottom pulley 13 drives the toothed belt 11 to operate. The teeth on the toothed belt 11 can be used to transport the protective cap.

[0032] The lower end of the UV module bracket 7 is provided with a protective cap loading container 6. The protective cap loading container 6 is provided with a vibration component for vibrating feeding. The vibration component includes a protective cap vibrating plate 16, which is installed at the bottom of the protective cap loading container 6. The bottom bracket 8 is rotatably connected to a rotating shaft 19 located below the protective cap loading container 6. The rotating shaft 19 is provided with a cam 17 for driving the protective cap vibrating plate 16 to vibrate. The base 1 is equipped with a drive component for driving the rotating shaft 19 to rotate.

[0033] During operation, the drive assembly drives the rotating shaft 19 to rotate, and the rotation of the rotating shaft 19 drives the cam 17 to move. The movement of the cam 17 continuously impacts the protective cap vibrating plate 16, thereby achieving the vibration of the protective cap vibrating plate 16.

[0034] The drive assembly includes a second motor 15, which is mounted on the upper surface of the base 1 on one side of the protective cap loading container 6. A first pulley 14 is mounted on both the output end of the second motor 15 and the end of the rotating shaft 19 closest to the second motor 15. A transmission belt 18 is installed between the two first pulleys 14; the first pulleys 14 are synchronous pulleys, and the transmission belt 18 is a synchronous belt. During operation, the second motor 15 drives the first pulleys 14 to rotate, which in turn drives the rotating shaft 19 to rotate under the action of the pulleys 18.

[0035] A vertical box 3 is provided on the other side of the upper surface of the base 1. The upper end of the vertical box 3 is connected to the upper end of the UV module bracket 7. The vertical box 3 is provided with a storage component for arranging and storing protective caps. The storage component includes a track 22, which is located at the upper end of the vertical box 3. The vertical box 3 is provided with a vertical storage compartment 20 for protective caps connected to the track 22. The upper end of the vertical box 3 is also provided with an orientation component connected to the UV module bracket 7 for adjusting the orientation of the protective film. A counter 21 for counting the protective caps is also installed at the upper end of the vertical box 3. The orientation component includes a V-shaped elastic vibrator 24, which is installed between the upper end of the vertical box 3 and the upper end of the UV module bracket 7. The V-shaped groove of the V-shaped elastic vibrator 24 is connected to the track 22. The other end of the V-shaped elastic vibrator 24 is connected to the UV module bracket 7. An orientation spring group 23 is installed inside the V-shaped elastic vibrator 24.

[0036] During operation, the protective caps are aligned with the wall by the directional spring group 23, and the opening orientation of the protective caps is selected. Only protective caps with openings facing down or up are allowed to pass through. The vibration of the V-shaped elastic vibrator 24 guides the protective caps into the track 22. The parabolic path set by the track 22 causes the protective caps to fall freely into the vertical storage bin 20. The counter 21 counts, monitors and controls the number of protective caps stored.

[0037] The base 1 is provided with a screening component for screening at the lower end of the vertical box 3. The screening component includes a third motor 26, a reduction mechanism is installed at the output end of the third motor 26, and a positioning disk 2 is installed at the output end of the reduction mechanism. Several U-shaped positioning holes 29 are arranged in a circular array at the inner edge of the positioning disk 2 below the vertical storage compartment 20 of the protective cap. Each U-shaped positioning hole 29 has a screening through hole 28 on its lower end face. The base 1 is provided with a positioning sensor 27 on one side of the positioning disk 2. The base 1 is provided with a visual recognition system 25 for identifying the opening direction of the protective cap near the third motor 26.

[0038] During operation, the third motor 26 is activated, and the positioning disk 2 moves clockwise, transferring the protective caps one by one from the vertical storage compartment 20 to the U-shaped positioning hole 29. The vision recognition system 25 identifies the opening direction of the protective caps, and protective caps with opening directions that do not meet the requirements are filtered out through the screening hole 28. The positioning sensor 27 positions the protective caps that meet the requirements for the robotic arm to grasp and use.

[0039] The working principle of this invention is as follows: The doctor puts the sterilized bulk vacuum blood collection tube protective cap into the protective cap loading container 6, starts the second motor 15, drives the cam 17 to make a circular motion, and the specific motion trajectory of the cam controls the protective cap vibrating plate 16 to make a fixed amplitude and fixed frequency vibration. The first motor 12 is started, triggering the toothed belt 11 inside the UV module bracket 7 to circulate. This picks up and transports the protective caps from the protective cap loading container 6, bringing them one by one into each tooth of the multi-toothed belt. The belt is then transported upwards. The cap diameter damper 10 dampens the caps with diameters larger than specified back into the protective cap loading container 6. The directional spring group 23 arranges the protective caps against the wall and filters the opening orientation of the caps, allowing only caps with openings facing down or up to pass through. The vibration of the V-shaped elastic vibrator 24 guides the protective caps to the track 22. The caps then fall freely into the vertical storage bin 20 along the parabolic path set by the track 22. The counter 21 counts, monitors, and controls the number of protective caps stored. The positioning sensor 27 is activated, and the positioning disk 2 moves clockwise, transferring the protective caps in the vertical storage bin 20 one by one into the U-shaped positioning hole 29. The visual recognition system 25 identifies the opening orientation of the protective caps, and protective caps with opening orientations that do not meet the requirements are filtered out through the screening through hole 28. The positioning sensor 27 positions the protective cap that meets the requirements for the robotic arm to grasp.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
