[0035] Now, in combination with the attached drawings, the present invention will be further elaborated.

[0036] Embodiment 1: As Figure 1-13 described, an automatic processing device for blood collection tubes includes a blood collection tube conveying mechanism 1, a labeling mechanism 12, a jig loading mechanism 17, a reagent adding mechanism 33, a drying mechanism 38, a capping mechanism 50, and a negative pressure mechanism 60. The above-mentioned blood collection tube conveying mechanism 1, labeling mechanism 12, jig loading mechanism 17, reagent adding mechanism 33, drying mechanism 38, capping mechanism 50, and negative pressure mechanism 60 are all installed on the frame. A labeling mechanism 12 is arranged above the blood collection tube conveying mechanism 1. At the head end of the blood collection tube conveying mechanism 1, there are multiple horizontal blood collection tubes placed in 2, 2. The blood collection tubes in 2 fall onto the blood collection tube conveying mechanism 1 for conveying. At the tail end of the blood collection tube, a jig loading mechanism 17 is docked. Through the jig loading mechanism 17, multiple blood collection tubes are clamped onto the jig 73 for conveying. At the same time, when the blood collection tubes are clamped onto the jig 73, the blood collection tubes are vertical, which is convenient for subsequent processing of the blood collection tubes. Below the jig loading mechanism 17, there is a conveying component 72 for conveying the jig 73. The jig 73 is placed on the conveying component 72 for conveying. Above the conveying component 72, there are successively arranged a reagent adding mechanism 33, a drying mechanism 38, a capping mechanism 50, and a negative pressure mechanism 60 that can be lifted and lowered. The jig 73 is conveyed on the conveying component 72, and the blood collection tubes on the jig 73 are successively docked with the reagent adding mechanism 33, the drying mechanism 38, the capping mechanism 50, and the negative pressure mechanism 60. In this way, the reagent addition, drying, capping, and negative pressure pumping of the blood collection tubes are completed in sequence, thus completing the automatic processing of the blood collection tubes; The jig 73 has upper and lower layers, and the upper and lower layers of the jig 73 are arranged oppositely. An elastic lifting component 74 is arranged between the upper and lower layers of the jig 73. The top edges of the upper and lower sides of the jig 73 are all set as rounded corners. When, the elastic lifting component 74 includes a vertical rod and a spring. Four vertical rods are fixed to the top of the lower layer of the jig 73 by means of bolts. The four vertical rods pass through the upper layer of the jig 73, and the upper layer of the jig 73 is lifted and lowered on the vertical rods. Threads are opened at the top of the vertical rods, and nuts for restricting the upper layer of the jig 73 from detaching from the vertical rods are installed on the threads. Springs are sleeved on the vertical rods. The springs are located between the upper layer of the jig 73 and the lower layer of the jig 73, and the upper and lower ends of the springs are respectively fixed to the upper layer of the jig 73 and the lower layer of the jig 73 by bolts. Clamping holes 75 that are opposite up and down are opened on the two layers of the jig 73. When working, each blood collection tube is inserted into the clamping holes 75 of the two layers of the jig 73, and the upper layer of the jig 73 is pressed downwards. The top of the blood collection tube protrudes from the upper layer of the jig 73, which is convenient for taking. The jig 73 limits the position of the blood collection tube, which is convenient for subsequent alignment operations; The fixture 73 mechanism 17 includes a transfer component 18, a spacer 19, and a temporary storage mold 20. Above the end of the blood collection tube conveying mechanism 1, there is a transfer component 18, which is multiple negative pressure tubes connected to a negative pressure pump. The negative pressure tubes are arranged side by side at the bottom of a flat plate and are installed at the bottom of the flat plate by bolts. An arc-shaped groove that fits the bottom of the blood collection tube is opened at the bottom of the negative pressure tube to facilitate the adsorption of the blood collection tube. On one side of the end of the blood collection tube conveying mechanism 1, there are multiple spacers 19 arranged side by side. The multiple spacers 19 are arranged at equal intervals. The transfer component 18 translates above the blood collection tube conveying mechanism 1 and the spacers 19. The transfer component 18 transports the blood collection needle at the end of the blood collection tube conveying mechanism 1 between the spacers 19. One blood collection tube is embedded between every two adjacent spacers 19. An inclined plate 25 is installed between two adjacent spacers 19 by welding. The end of the inclined plate 25 away from the blood collection tube conveying mechanism 1 slopes downward. When the transfer component 18 transports the blood collection tube between the spacers 19, the blood collection tube slides downward along the inclined plate 25. Below the inclined plate 25, there is a temporary storage mold 20 that can translate left and right. A fixture 73 is placed on the conveying component 72 directly below the temporary storage mold 20. The temporary storage mold 20 is provided with a first lifting component 26, which is a cylinder for lifting. The piston rod of the first lifting component 26 is fixed to the upper mold 21 by bolts. A translation seat 57 is fixed to the cylinder body of the first lifting component 26 by bolts. A translation rail is installed on the frame by bolts. The translation seat 57 is stuck on the translation rail for left and right translation. Both ends of the flat plate are located above the translation seat 57. A cylinder for lifting the flat plate is installed between the translation seat 57 and both ends of the flat plate by bolts. When the translation seat 57 moves to the left end of the translation rail, the transfer component 18 is directly above the end of the blood collection tube conveying mechanism 1. When the translation seat 57 moves to the right end of the translation rail, the transfer component 18 is directly above the spacers 19. The blood collection tube transported by the transfer component 18 is between the spacers 19. When the transfer component 18 releases the blood collection tube, the blood collection tube falls onto the inclined plate 25 and slides downward into the temporary storage mold 20. A bottom sealing module 27 is arranged at the bottom of the temporary storage mold 20. When the temporary storage mold 20 descends, the bottom sealing module 27 opens. The temporary storage mold 20 corresponds to the fixture 73 up and down. The blood collection tube falls onto the fixture 73 for clamping, and then the fixture 73 moves backward to complete the assembly of multiple workstations in sequence.

[0037] The blood collection tube conveying mechanism 1 is two sections of synchronous chains 8. The two sections of synchronous chains 8 are arranged side by side front and back. The synchronous chain 8 at the front end is the first synchronous chain 8, and the synchronous chain 8 at the back end is the second synchronous chain 8. The first synchronous chain is horizontally arranged, and the second synchronous chain 8 is inclined upward. The purpose of the second synchronous chain 8 being inclined upward is to raise the height of the blood collection tube. Both sections of synchronous chains 8 are driven by sprockets 9 driven by a motor. The sprockets 9 are installed on the frame through bearings, and the sprockets 9 are engaged with the corresponding synchronous chains 8, thus completing the movement of the synchronous chains 8. The two sections of synchronous chains 8 move synchronously. A plurality of rollers 10 arranged at equal intervals are installed on each section of synchronous chain 8 through bearings. The rollers 10 can rotate. The blood collection tubes are placed horizontally between two rollers 10. Above the front ends of the two sections of synchronous belts, there are both 2s. Both 2s are installed on the frame through bolts. A material transfer component 11 is arranged between the two sections of synchronous chains 8. An annular notch is opened on each roller 10. A discharge plate is inserted into the end of the first synchronous belt. The discharge plate is inserted into the annular notch of the roller 10. In this way, the blood collection tubes on the synchronous chain 8 are placed above the discharge plate. A motor is installed on the frame above the discharge plate. The output shaft of the motor is fixed with blades distributed in an annular array by welding. The blood collection tubes are pushed by the blades. The other end of the discharge plate passes through the front side wall of the second 2. A rectangular hole for the blood collection tube to pass through is additionally opened on the front side wall of the second 2. The blood collection tubes on the first synchronous chain 8 are transferred to the 2 of the second synchronous chain 8 through the material transfer component 11;Each 2 includes a bucket body 3, a swing plate 4, a discharge cam 5 and a guide groove 6. Among them, a guide groove 6 communicating with the bottom of the bucket body 3 is installed on the frame below the bucket body 3 by means of bolt fastening. The width of the guide groove 6 is consistent with the diameter of the blood collection tube. The bottom of the guide groove 6 is butted with the synchronous chain 8. When the blood collection tube is placed on the roller 10, the bottom of the blood collection tube is at the same height as the bottom of the catheter groove. A swing plate 4 is arranged between the guide groove 6 and the bucket body 3. The swing plate 4 is hinged to the outer wall on the right side of the bucket body 3. The swing plate 4 swings. Two discharge cams 5 are installed on the frame above the guide groove 6 through bearings. The discharge cams 5 are located on the left and right sides of the guide groove 6. The two discharge cams 5 are driven by a motor. The discharge cam 5 on the right squeezes the blood collection tube above the guide groove 6, and the discharge cam 5 on the left squeezes the blood collection tube upward. In this way, when working, it is squeezed to the left by the discharge cam 5 on the right, so that the blood collection tube moves above the guide groove 6, and the blood collection tube moves downward along the guide groove 6. The discharge cam 5 on the left pushes the blood collection tube upward (a cavity is formed at the feed port of the guide groove 6. When the blood collection tube moves to the feed port of the guide groove 6, the blood collection tube enters the guide groove 6). In this way, it can be avoided that the blood collection tube is blocked at the feed port part of the guide groove 6. A swing eccentric wheel 7 is installed on the discharge cam 5 by means of bolt fastening. The swing plate 4 presses on the swing eccentric wheel 7. The swing eccentric wheel 7 rotates synchronously with the discharge cam 5. In this way, when discharging, the eccentric wheel rotates and the swing plate 4 swings up and down, so as to vibrate the blood collection tube in the bucket body 3, which is convenient for the blood collection tube to flow in the bucket body 3.;

[0038] The labeling mechanism 12 includes a label unwinding reel 13, a label winding reel 14 and a pressing belt 15. The label unwinding reel 13 and the label winding reel 14 are installed on the frame through bearings. The label winding reel 14 is connected to the output shaft of the motor, so that the label winding reel 14 winds. Among them, the label roll is unwound while sleeved on the label unwinding reel 13, and the anti-sticking tape of the label roll is wound on the label winding reel 14 (the labels on the label roll are sticky, so the sticky side of the label is adhered to the anti-sticking tape. Multiple holes are punched between adjacent labels to form a tear line. When two opposite pulling forces are generated at the tear line of two labels, the tear line between the labels will be torn into two separate labels). Above the blood collection tube conveying mechanism 1, there is a guide plate 16 with a rear end inclined downward. The guide plate 16 is installed on the frame through bolts. The rear end of the guide plate 16 is 2 mm higher than the top of the blood collection tube. The label and the anti-sticking tape are separated at the guide plate 16. The label is separated from the anti-sticking tape and adhered to the blood collection tube. On the frame behind the guide plate 16, there is a pressing belt 15. The pressing belt 15 presses on the outer wall of the blood collection tube. The pressing belt 15 is sleeved on a roller 10 driven by a motor. The pressing belt 15 is driven by the roller 10. When the blood collection tube with the label adhered moves under the pressing belt 15, the blood collection tube is driven to rotate by the pressing belt 15, so that the label is completely adhered to the outer wall of the blood collection tube. At the same time, the label is separated from the previous label, thus completing the labeling. The blood collection tube continues to rotate under the pressing belt 15, so that the label and the blood collection tube are closely attached.

[0039] The temporary storage mold 20 includes an upper mold 21 and a lower mold 22. The upper mold 21 and the lower mold 22 are fixed by connecting rods. There are four connecting rods, and the four connecting rods are fixed to the upper mold 21 and the lower mold 22 by bolts, thus realizing the fixation of the upper mold 21 and the lower mold 22. A plurality of placement holes 23 distributed in a rectangular array are formed in the upper mold 21. The placement holes 23 are sequentially butted against the bottom of the inclined plate 25 through the translation of the upper mold 21. A slot 24 is formed in the lower mold 22 and is arranged opposite to the placement hole 23 up and down. The lower end of the blood collection tube is inserted into the fork slot, and the upper end of the blood collection tube is inserted into the placement hole 23. The upper end of the blood collection tube is immersed in the placement hole 23. A bottom sealing module 27 is arranged at the bottom of the lower mold 22, and the placement hole 23 at the bottom of the lower mold 22 is blocked by the bottom sealing module 27 to prevent the blood collection needle from falling downward. When receiving materials, when the blood collection tube slides on the inclined plate 25 and is inserted into the placement hole 23 and the slot 24, then the temporary storage mold 20 moves one grid to the right, and the distance of one grid is the center distance between two placement holes 23. In this way, the temporary storage mold 20 is filled with blood collection tubes. The temporary storage mold 20 moves downward and presses on the top of the fixture 73. In this way, the bottom sealing module 27 releases the blockage of the slot 24, and the blood collection tubes on the temporary storage mold 20 fall into the fixture 73; The bottom sealing module 27 includes a sliding rod 28, a lifting rod 29 and a sealing cloth 30. Among them, a sliding rod 28 is arranged below each row of slots 24. A horizontal chute is formed at the bottom of the lower mold 22, and the sliding rod 28 moves left and right in the horizontal chute. A return spring 31 is fixed between the sliding rod 28 and the end face of the chute of the lower mold 22 by means of bolts. A lifting rod 29 is arranged between the two sliding rods 28. A vertical chute is formed in the lower mold 22, and the vertical chute is communicated with the horizontal chute. The lifting rod 29 moves up and down in the vertical chute. Trigger rods 32 extending downward are fixed to the lower parts of both ends of the lifting rod 29 by welding. The trigger rods 32 protrude from the bottom of the lower mold 22. When the lower mold 22 descends and fits with the top of the fixture 73, the trigger rods 32 abut against the top of the fixture 73, and the trigger rods 32 move upward. In this way, the lifting rod 29 moves upward relative to the fixture 73. A sealing cloth 30 is arranged between the sliding rod 28 and the lifting rod 29. Both ends of the sealing cloth 30 are fixed to the sliding rod 28 and the lifting rod 29 by glue. When the trigger rods 32 are pressed and retracted into the lower mold 22, the lifting rod 29 is pushed upward, and the sliding rod 28 moves toward the vertical chute under the traction of the sealing cloth 30. In this way, the sealing cloth 30 leaves the bottom of the slot 24, and the bottom of the slot 24 is opened, and the blood collection tubes fall into the fixture 73. When the temporary storage mold 20 rises, under the action of the return spring 31, the sliding rod 28 moves away from the vertical chute, and the sealing cloth 30 blocks the bottom of the slot 24.
