[0029] See also Figure 1 , Figure 2 and Figure 3 The carrier tray buffer device 10 provided by one embodiment of the present invention is used to sort and sort the carriers 30 with test tubes to be tested so as to transport them to the corresponding trays 20, and at the same time, the carriers 30 are recycled. The carrier tray buffer device 10 includes a conveying mechanism 11, two buffer units 12 and a workbench 13. The two buffer units 12 can be symmetrically distributed on opposite sides of the conveying mechanism 11. Figure 4 Each buffer unit 12 includes a base 100 , a pushing mechanism 200 and a toggle mechanism 300 .

[0030] See also Figure 1 In some embodiments, a receiving space 14 is provided on the workbench 13. There may be multiple receiving spaces 14, and the multiple receiving spaces 14 are independently provided. The receiving spaces 14 can be used to hold the tray 20. Figure 5 and Figure 6The base 100 includes a first support frame 110, a second support frame 120, a baffle 131 and a guide plate 132. The first support frame 110 and the second support frame 120 are arranged at intervals in the vertical direction, and the second support frame 120 is located above the first support frame 110. The second support frame 120 is provided with a slide groove 123, and the slide groove 123 can extend horizontally. The second support frame 120 can be provided with a positioning member such as a pin, and the pin protrudes a certain height in the vertical direction relative to the surface of the second support frame 120. A positioning hole can be provided on the tray 20. When the positioning hole cooperates with the pin, the tray 20 can be installed and positioned on the base 100. Of course, positioning members such as pins can be provided on the tray 20, and the positioning hole can be provided on the second support frame 120. The second support frame 120 may be provided with a plurality of mounting positions 124 for placing the tray 20. For example, the number of mounting positions 124 may be four. The number of mounting positions 124 may be appropriately increased according to actual needs, so that the number of mounting positions 124 on the second support frame 120 may be less than or greater than four. The structures of the slide slots 123 and the pins corresponding to the mounting positions 124 may be slightly changed to adapt to the shape of the tray 20. In other words, it is customized according to the tray 20 placed.

[0031] The baffle 131 is vertically arranged and can be connected to the first support frame 110. The guide plate 132 is horizontally arranged and can be fixed to the baffle 131 by screw connection. The guide plate 132 is bent and connected to the baffle 131. For example, the baffle 131 is bent 90 degrees relative to the guide plate 132, so that the guide plate 132 and the baffle 131 are perpendicular to each other, and then the guide plate 132 and the baffle 131 are connected to form an L-shaped structure, and the two together enclose a conveying channel 133. Both the guide plate 132 and the baffle 131 extend in a horizontal longitudinal direction, so that the conveying channel 133 also extends in a horizontal longitudinal direction. The conveying channel 133 can be used to convey the carrier 30. The gravity of the carrier 30 directly acts on the guide plate 132. The baffle 131 presses against the carrier 30 in the horizontal direction to play a limiting role. Through the joint action of the baffle 131 and the guide plate 132, the carrier 30 can slide along the extension direction of the conveying channel 133. The baffle 131 is also provided with a through hole 131a. The through hole 131a penetrates two oppositely arranged surfaces of the baffle 131 to form a through hole. The through hole 131a is connected to the conveying channel 133. The number of the through holes 131a can be multiple. The multiple through holes 131a are arranged at intervals along the horizontal longitudinal direction. The number of the through holes 131a is equal to the number of the mounting positions 124 on the second support frame 120. At the same time, the through holes 131a and the mounting positions 124 form a one-to-one correspondence. The shape of the through hole 131a can be a long strip hole, such as a rectangular hole, a waist-shaped hole or an elliptical hole.

[0032] See also Figure 5In some embodiments, the number of the pushing mechanism 200 and the mounting position 124 are equal, and the pushing mechanism 200 and the mounting position 124 form a one-to-one correspondence. The pushing mechanism 200 includes a first linear module 210 and a pushing member 220. The first linear module 210 can adopt a screw motor module, etc. In other embodiments, the first linear module 210 can also adopt a synchronous belt drive module. The first linear module 210 is installed on the first support frame 110, and the pushing member 220 is connected to the first linear module 210. The pushing member 220 can be roughly a curved rod-shaped structure. The structure of different pushing members 220 can be slightly changed to adapt to the shape of the corresponding tray 20. The pushing member 220 is arranged in the slide groove 123 on the second support frame 120, so that the pushing member 220 forms a sliding fit relationship with the slide groove 123, and the pushing member 220 can protrude a certain height from the upper surface of the second support frame 120. When the first linear module 210 is working, the slide groove 123 extends horizontally, thereby driving the pusher 220 to reciprocate horizontally. The upper surface of the guide plate 132 can be flush with the surface of the tray 20 used to support the carrier 30, that is, the two are at the same height relative to the first support frame 110 in the vertical direction. When the first linear module 210 drives the pusher 220 to abut against the carrier 30 and move close to the conveying channel 133, it can be ensured that the pusher 220 can smoothly push the carrier 30 from the tray 20 to the conveying channel 133.

[0033] See also Figure 7 , Figure 8 and Fig. 9 In some embodiments, the toggle mechanism 300 includes a toggle member 310, a fixed plate 320, a drive motor 330, and a cam assembly 340. The fixed plate 320 may be a substantially flat U-shaped structure, and the fixed plate 320 may be fixed to the first support frame 110 of the base 100 by bolt connection. The drive motor 330 may be a servo motor, and the drive motor 330 may be fixed to the fixed plate 320. The toggle member 310 is slidably disposed on the fixed plate 320, for example, a linear guide 321 may be installed on the fixed plate 320, and the linear guide 321 extends horizontally, and a slider is installed on the toggle member 310, and a groove is provided on the slider, and the linear guide 321 is slidably matched with the groove. Of course, in other embodiments, the linear guide 321 may also be installed on the toggle member 310, and a slider is installed on the fixed plate, and a groove is provided on the slider to slide with the linear guide 321. The cam assembly 340 is connected to the drive. When the drive motor 330 moves, the cam assembly 340 can be driven to rotate, and then the cam assembly 340 drives the toggle member 310 to slide relative to the fixed plate 320.

[0034] Specifically, the cam assembly 340 includes a rotating shaft 341, a rotating disk 342, and an eccentric shaft 343. The cross section of the rotating disk 342 may be circular, that is, the rotating disk 342 may be a disc. The rotating shaft 341 and the eccentric shaft 343 are connected to opposite sides of the rotating disk 342, for example, the rotating shaft 341 is connected to the lower surface of the rotating disk 342, and the eccentric shaft 343 is connected to the upper surface of the rotating disk 342. The rotating shaft 341 and the rotating disk 342 are coaxially arranged, that is, the central axis of the rotating shaft 341 and the central axis of the rotating disk 342 coincide with each other, the rotating shaft 341 is connected to the output shaft of the driving motor 330, and at the same time, the central axis of the eccentric shaft 343 does not coincide with the central axis of the rotating disk 342, so that the central axis of the eccentric shaft 343 and the central axis of the rotating disk 342 are arranged at intervals. A guide groove 311 a is formed on the toggle member 310 . The guide groove 311 a can extend in a horizontal longitudinal direction. The eccentric shaft 343 passes through the guide groove 311 a , so that the eccentric shaft 343 and the guide groove 311 a form a sliding fit relationship.

[0035] The toggle member 310 includes a slide plate 311, a connecting plate 312 and a convex plate 313. The slide plate 311 is horizontally arranged and extends in a horizontal longitudinal direction, and the connecting plate 312 is vertically arranged. The slide plate 311 is slidably connected to the fixed plate 320, so that the slide plate 311 is slidably arranged on the fixed plate 320, the guide groove 311a is arranged on the slide plate 311, and the connecting plate 312 is bent and connected to the slide plate 311, for example, the connecting plate 312 is bent ninety degrees relative to the slide plate 311, that is, the connecting plate 312 and the slide plate 311 are perpendicular to each other. The convex plate 313 is connected to the connecting plate 312, and the convex plate 313 protrudes relative to the surface of the connecting plate 312. There are multiple convex plates 313, and the multiple convex plates 313 are spaced apart on the connecting plate 312. The number of the convex plates 313 is equal to the number of the through holes 131a on the baffle 131, that is, the convex plates 313 and the through holes 131a form a one-to-one correspondence. When the slide plate 311 slides relative to the fixed plate 320 and approaches the conveying channel 133, the protrusion 313 can move in the through hole 131a, thereby pushing the carrier 30 in the conveying channel 133 into the tray 20. Of course, for the carrier 30 pushed by the protrusion 313, the carrier 30 is loaded with a test tube.

[0036] The cam assembly 340 may further include a guide wheel 344 and two positioning blocks 345. The two positioning blocks 345 may be fixed on the slide plate 311. The positioning blocks 345 protrude a certain height relative to the surface of the slide plate 311. The two positioning blocks 345 are located on opposite sides of the guide groove 311a, that is, the guide groove 311a is located between the two positioning blocks 345. The guide wheel 344 is arranged at the upper end of the eccentric shaft 343. For example, the guide wheel 344 is rotatably connected with the eccentric shaft 343. When the eccentric shaft 343 is inserted into the guide groove 311a, the guide wheel 344 abuts against the positioning blocks 345. By providing the guide wheel 344, the resistance generated by the entire toggle mechanism 300 during the movement can be reduced, thereby reducing the wear generated by the toggle mechanism 300.

[0037] In fact, for example, when the output shaft of the driving motor 330 rotates a certain angle, the eccentric shaft 343 can be moved close to the conveying channel 133, and the guide wheel 344 applies a force toward the conveying channel 133 to the entire toggle member 310 in the horizontal lateral direction through the positioning block 345, and the toggle member 310 moves close to the conveying channel 133 in the horizontal lateral direction along the fixing plate 320, so that the convex plate 313 applies a force to the carrier 30 loaded with the test tube on the conveying channel 133 through the through hole 131a, and finally the carrier 30 loaded with the test tube is transported from the conveying channel 133 to the tray 20. Obviously, when the output shaft of the driving motor 330 continues to rotate a certain angle in the opposite direction, the eccentric shaft 343 can be moved away from the conveying channel 133, and the toggle member 310 can be moved away from the conveying channel 133, so as to prepare for the next push of the carrier 30 loaded with the test tube.

[0038] See also Figure 5 and Figure 6In some embodiments, the transport mechanism 11 includes a second linear module 410, a bracket 420, a transport member 430, a power motor 441, a gear 442, and a rack 443. The second linear module 410 can adopt a screw motor module, etc. In other embodiments, the second linear module 410 can also adopt a synchronous belt drive module. The second linear module 410 can be connected to the base 100, the bracket 420 is connected to the second linear module 410, and the second linear module 410 can drive the bracket 420 to move horizontally and longitudinally. The transport member 430 is arranged on the bracket 420. When the transport member 430 abuts against the carrier rack 30 on the conveying channel 133, in the process of the transport member 430 sliding along the longitudinal direction following the bracket 420, the transport member 430 can push the carrier rack 30 to slide in the conveying channel 133. For example, the empty carrier rack 30 in the conveying channel 133 can be pushed out of the entire carrier rack tray buffer device 10 to enter the loading unit, and the carrier rack 30 loaded with the test tube to be tested can be slid to the specified position in the conveying channel 133, and the carrier rack 30 loaded with the tested test tube can be slid out of the conveying channel 133 to enter the post-processing unit.

[0039] The power motor 441 is arranged on the bracket 420, the gear 442 is arranged on the output shaft of the power motor 441, and the rack 443 is arranged on the transport member 430, and the gear 442 and the rack 443 are meshed with each other. The transport member 430 is slidably connected with the bracket 420. For example, a linear guide 421 can be installed on the bracket 420, and the linear guide 421 extends horizontally, and a slider is installed on the transport member 430, and a groove is provided on the slider, and the linear guide 421 is slidably matched with the groove. Of course, in other embodiments, the linear guide 421 can also be installed on the transport member 430, and a slider is installed on the bracket 420, and a groove is provided on the slider to slide with the linear guide 421.

[0040] When the power motor 441 rotates, the meshing relationship between the gear 442 and the rack 443 can drive the transport member 430 to slide back and forth horizontally on the bracket 420. When the transport member 430 slides close to the conveying channel 133 on one of the buffer units 12, the transport member 430 can abut against the carrier 30 in the conveying channel 133, thereby pushing the carrier 30 to slide in the conveying channel 133.

[0041] See also Figure 1In some embodiments, the carrier tray buffer device 10 also includes a frame 15, which is connected to the base 100, so that the pushing mechanism 200 and the toggle mechanism 300 on the two buffer units 12 are both located in the cavity formed by the frame 15, that is, the frame 15 can protect the pushing mechanism 200 and the toggle mechanism 300. The frame 15 is also provided with four circulation openings, each of which corresponds to a circulation opening at both ends of each conveying channel 133. The circulation opening corresponding to one end of the conveying channel 133 is recorded as the first circulation opening 16, and the circulation opening corresponding to the other end of the conveying channel 133 is recorded as the second circulation opening 17. Both the first circulation opening 16 and the second circulation opening 17 are connected to the same conveying channel 133. An empty carrier rack 30 in the conveying channel 133 can be output to the outside of the entire carrier rack tray buffer device 10 through one of the first circulation openings 16, and a carrier rack 30 loaded with untested test tubes can enter the conveying channel 133 of the carrier rack tray buffer device 10 from the outside through another circulation opening 16. A carrier rack 30 loaded with tested test tubes in the conveying channel 133 can be output to the outside of the entire carrier rack tray buffer device 10 through one of the second circulation openings 17, and an empty carrier rack 30 with unloaded test tubes can be input into the conveying channel 133 through another second circulation opening 17.

[0042] When working, for the convenience of description, the two buffer units 12 are respectively recorded as the first buffer unit 121 and the second buffer unit 122. In the first step, the pushing mechanism 200 on the first buffer unit 121 moves, so that the first linear module 210 drives the pushing member 220 to move toward the conveying channel 133. When the pushing member 220 abuts against the empty carrier frame 30 on the tray 20, the pushing member 220 pushes the empty carrier frame 30 from the tray 20 to the conveying channel 133 on the first buffer unit 121. In the second step, the power motor 441 of the transport mechanism 11 works, so that the transport member 430 moves horizontally toward the conveying channel 133 on the first buffer unit 121. When the transport member 430 abuts against the empty carrier rack 30, the second linear module 410 works, so that the transport member 430 follows the bracket 420 to slide toward the flow port 16 along the horizontal longitudinal direction, so that the empty carrier rack 30 is output from one of the first flow ports 16 to the loading unit located outside the carrier rack tray buffer device 10, and the loading unit loads the test tube to be tested into the empty carrier rack 30. In the third step, when the carrier 30 loaded with test tubes is input from another first flow port 16 to the conveying channel 133 on the second buffer unit 122, the power motor 441 of the conveying mechanism 11 works, so that the conveying member 430 moves horizontally toward the conveying channel 133 on the second buffer unit 122, so that the conveying member 430 abuts against the carrier 30 loaded with test tubes, and then the second linear module 410 is started, so that the conveying member 430 follows the bracket 420 to slide horizontally and longitudinally, and the carrier 30 loaded with test tubes is moved to a specified position in the conveying channel 133 on the second buffer unit 122 according to the type of test tube and the inspection item to be performed on the test tube. In the fourth step, the toggle mechanism 300 on the second buffer unit 122 works, and the driving motor 330 drives the eccentric shaft 343 to move close to the conveying channel 133 on the second buffer unit 122, so that the toggle member 310 moves close to the conveying channel 133. When the toggle member 310 abuts against the carrier rack 30 loaded with the test tube, the toggle member 310 can push the carrier rack 30 from the conveying channel 133 on the second buffer unit 122 to the corresponding tray 20.In the fifth step, when a reasonable number of carrier racks 30 loaded with test tubes are placed in the tray 20 on the second buffer unit 122, the tray 20 can be taken away from the second buffer unit 122 and transported to the corresponding testing equipment according to the test tube type and the test items to be performed on the test tubes. After the test items are completed, the tray 20 with the tested test tubes can be put back to the corresponding position of the second buffer unit 122, and then the pushing mechanism 200 pushes the carrier rack 30 loaded with the tested test tubes to the conveying channel 133 of the second buffer unit 122, and the transporting mechanism 11 pushes the carrier rack 30 loaded with the tested test tubes from one of the second flow ports 17 into the post-processing unit until all the tested carrier racks 30 in the tray 20 are transported. The tray 20 can be loaded with the test tube rack 30 to be tested again and used repeatedly.

[0043] In short, the entire movement process of the carrier tray buffer device 10 can be summarized as follows: first, the carrier 30 without test tubes loaded is pushed out from the tray 20 to the conveying channel 133 of the first buffer unit 121, and then the empty carrier 30 is pushed out from one of the first flow ports 16 by the transport mechanism 11 and transported to the loading unit; second, after loading is completed, the carrier 30 loaded with test tubes to be tested is transported to the conveying channel 133 of the second buffer unit 122, and then the transport mechanism 11 transports the carrier 30 loaded with test tubes to be tested to the position corresponding to its tray 20, and then the toggle mechanism 300 pushes the carrier 30 loaded with test tubes to be tested into the tray 20; third, the medical staff loads the test tubes to be tested The tray 20 of the test tube is taken away and sent to the corresponding testing equipment. After the test is completed, the tray 20 with the tested test tube is put back to the corresponding position of the second buffer unit 122; fourth, the pushing mechanism 200 pushes the tested carrier 30 to the conveying channel 133 of the second buffer unit 122, and then the conveying mechanism 11 pushes the tested carrier 20 out from one of the second flow ports 17 and transports it to the post-processing unit; fifth, the post-processing unit takes out the tested test tube from the carrier 30, stores it in the low-temperature storage unit, and then uses the track to allow the empty carrier 30 to enter the conveying channel 133 of the first buffer unit 121 from another second flow port 17, waiting to be loaded with new test tubes to be tested again.

[0044] Therefore, the carrier tray buffer device 10 replaces manual labor to sort and organize the carriers 30 containing the test tubes to be tested so as to transport them to the corresponding trays 20, which greatly improves the efficiency of sorting and organizing. At the same time, the carrier tray buffer device 10 also replaces manual labor to recycle the carriers 30, thereby increasing the utilization rate of the carriers 30, reducing the cost of the carriers, and saving a lot of labor costs.

[0045] The technical features of the above-described embodiments may be arbitrarily combined.
