[0035] It is understandable that, referring to Figures 1 to 5The test tube feeding device of the first embodiment of the utility model comprises a feeding mechanism 100, a classification mechanism 200 and a transfer mechanism 300. The feeding mechanism 100 comprises a silo 110, a conveying assembly 120 and a barcode scanner 130. The silo 110 is used to store the test tubes. The conveying assembly 120 comprises a first driving member 121, a fixed plate 122 and a movable plate 123. The fixed plate 122 is arranged adjacent to the silo 110. The end of the movable plate 123 can receive the test tube. The first driving member 121 is used to drive the movable plate 123 to move up and down on one side of the fixed plate 122 so that the test tube can roll on the fixed plate 122. The barcode scanner 130 is arranged above the fixed plate 122 to identify the barcode of the test tube. The classification mechanism 200 comprises a first classification assembly 21 0 and a second classification component 220, the first classification component 210 includes a first conveying gap 211, the first conveying gap 211 is arranged at the upper end of the fixed plate 122 to receive the test tubes, the test tubes include thin test tubes and thick test tubes, the first conveying gap 211 is smaller than the outer diameter of the tube cap of the thin test tube, and larger than the outer diameter of the tube body of the thin test tube, the second classification component 220 includes a push plate 221 and a second driving member 222, the push plate 221 is arranged on one side of the first conveying gap 211, the second driving member 222 is used to drive the push plate 221 to move in a direction close to the first conveying gap 211, so as to drive the thick test tube to slide out of the first conveying gap 211; the transfer mechanism 300 is arranged at the output end of the first conveying gap 211, and the transfer mechanism 300 is used to transfer thin test tubes and / or thick test tubes.

[0036] The test tube is placed in the silo 110, and the fixed plate 122 is arranged adjacent to the silo 110. The first driving member 121 drives the movable plate 123 to move up and down on one side of the fixed plate 122, so that the movable plate 123 can move in the silo 110 to drive the test tube to rise from the silo 110, so that the test tube can roll on the fixed plate 122, so that the scanner 130 can easily identify the barcode on the side wall of the test tube, realize automatic identification of the test tube, and there is no need to manually enter the test tube information, thereby improving the loading efficiency of the test tube. The test tubes include thick test tubes and thin test tubes. After the test tubes are output from the end of the fixed plate 122, they can be stabilized in the first conveying gap 211. The first conveying gap 211 is smaller than the outer diameter of the cap of the thin test tube and larger than the outer diameter of the body of the thin test tube, so that the cap of the thin test tube can be supported on the first conveying gap 211, so that after the thin test tube is output from the fixed plate 122, the thin test tube can stand upright in the two first conveying gaps 211, and the thick test tube can be arranged horizontally in the first conveying gap 211, so that the thin test tube and the thick test tube can be distinguished. The push plate 221 is arranged on one side of the first conveying gap 211, and the push plate 221 is connected to the movable end of the second driving member 222. The push plate 221 is driven by the second driving member 222 to move in the direction close to the first conveying gap 211, so that the push plate 221 can push the thick test tube to slide out of the first conveying gap 211. The transfer mechanism 300 is disposed at the output end of the first conveying gap 211. The transfer mechanism 300 can transfer thin test tubes and / or thick test tubes, thereby realizing automatic sorting of the test tubes, reducing manual participation, lowering labor intensity, and improving the feeding efficiency of the test tubes.

[0037] It should be noted that the test tube includes a thin test tube and a thick test tube, and the test tube includes a tube body and a tube cap. The test tube is divided into a thin test tube and a thick test tube according to the diameter of the tube body to accommodate different samples. The test tube is driven to roll on the wall of the fixed plate 122 by the movable plate 123, so that the test tube can be pushed out of the fixed plate 122 and move to the first conveying gap 211. When the test tube is a thin test tube, the tube body of the thin test tube falls into the first conveying gap 211, and the tube cap of the thin test tube is supported on the first conveying gap 211, so that the thin test tube is placed vertically; when the test tube is a thick test tube, the tube body of the thick test tube is placed horizontally between the two first conveying gaps 211, and the thick test tube can be driven to be pushed out from one side of the first conveying gap 211 by the push plate 221, so that the thin test tube and the thick test tube can be distinguished, without manual sorting, thereby improving the sorting efficiency of the test tubes.

[0038] The number of fixed plates 122 and movable plates 123 can be multiple, and the multiple fixed plates 122 and movable plates 123 are arranged in the vertical direction, and the fixed plates 122 and movable plates 123 are arranged alternately in the horizontal direction, and the fixed plates 122 and movable plates 123 are arranged obliquely, so that the test tube can be stabilized on the wall surface of the fixed plate 122, thereby improving the transportation stability of the test tube. In addition, the first driving member 121 can be a motor that drives the multiple movable plates 123 to move synchronously up and down through a belt transmission, or a linear cylinder or an electric push rod that drives the multiple movable plates 123 to move synchronously up and down.

[0039] It is understandable that, referring to Figure 4 and Figure 5 The second driving member 222 includes a motor 223, a gear 224 and a rack 225. The gear 224 is fixedly connected to the output end of the motor 223, the gear 224 meshes with the rack 225, and the push plate 221 is fixedly connected to the rack 225. The motor 223 drives the gear 224 to rotate, so as to drive the rack 225 to move in the horizontal direction, thereby driving the push plate 221 to move in the direction close to the first conveying gap 211, so as to facilitate the thick test tube to be pushed out from the first conveying gap 211. In addition, the second driving member 222 can also be a linear cylinder or an electric push rod, which will not be described in detail here.

[0040] It is understandable that, referring to Figure 1 , Figure 2 and Figure 8 The transfer mechanism 300 includes a gripper assembly 310 and a transfer assembly 320. The gripper assembly 310 includes a moving part 311 and a clamp 315. The moving part 311 is used to drive the clamp 315 to move. The clamp 315 is used to clamp the test tube. The transfer assembly 320 includes a first conveyor belt 321 and a plurality of support tubes 322. The plurality of support tubes 322 are fixedly connected to the first conveyor belt 321. The first conveyor belt 321 is used to drive the support tubes 322 to move. The support tubes 322 are provided with a accommodating groove 323 for accommodating the test tube. The movable part 311 can drive the clamp 315 to move so that the clamp 315 can move to the output end of the first conveying gap 211, and then the clamp 315 clamps the test tube, and the movable part 311 drives the clamp 315 to move to the support tube 322, and the test tube is placed in the accommodating groove 323. The support tube 322 is driven to move by the first conveyor belt 321 to adjust the position of the support tube 322, so that the test tube can be transferred, which is convenient for testing the sample, without the need for manual handling of the test tube, reducing labor intensity and improving sorting efficiency.

[0041] Further, see Figure 8The moving part 311 includes a first translation part 312, a second translation part 313 and a lifting part 314. The clamp 315 is arranged on the lifting part 314. The lifting part 314 is arranged on the second translation part 313. The second translation part 313 is arranged on the first translation part 312. The movement directions of the first translation part 312, the second translation part 313 and the lifting part 314 are perpendicular to each other, so that the clamp 315 can be driven to move flexibly, which is convenient for the transfer of the test tube.

[0042] It can be understood that the first translation component 312, the second translation component 313 and the lifting component 314 are three directions of the spatial rectangular coordinate system. The first translation component 312 can also be set on the second translation component 313, and the lifting component 314 can be set on the first translation component 312, so as to realize the movement of the spatial position, which is not elaborated here.

[0043] Among them, the first translation component 312, the second translation component 313 and the lifting component 314 can all be driven by a motor through a belt drive, or can be driven by a linear cylinder or an electric push rod, which will not be described in detail here.

[0044] Further, see Figure 4 and Figure 8 A first lifting seat 332 is disposed below the first conveying gap 211, and the first lifting seat 332 is connected to a fourth driving member 331. The fourth driving member 331 drives the first lifting seat 332 to rise, so that the first lifting seat 332 can support the thin test tube, and drive the thin test tube to extend out of the first conveying gap 211, so that the clamping claw 315 can clamp the thin test tube, thereby improving the clamping success rate of the test tube and improving the transfer efficiency of the test tube. The fourth driving member 331 can be a linear cylinder or an electric push rod, which is not limited here.

[0045] Specifically, refer to Figure 1 and Figure 2 The upper end of the receiving groove 323 is provided with a guide portion 324, which is in a conical shape, and the diameter of the guide portion 324 gradually decreases toward the receiving groove 323, so as to guide the test tube to slide into the receiving groove 323. The guide portion 324 is provided at the upper end of the receiving groove 323, and the guide portion 324 is provided in a conical shape so that the diameter of the guide portion 324 gradually decreases toward the receiving groove 323, so that when the clamp 315 drives the test tube to be placed into the receiving groove 323, the end of the test tube can abut against the guide portion 324, so that the test tube can be guided to slide into the receiving groove 323, so as to facilitate the transfer of the test tube, avoid the test tube being clamped between the clamp 315 and the end of the receiving groove 323, and reduce the possibility of damaging the test tube.

[0046] It is understandable that, referring to Figure 1 , Figure 5 , Figure 6and Figure 8 The second classification component 220 also includes a second conveying gap 226. The second conveying gap 226 is smaller than the outer diameter of the tube cap of the thick test tube and larger than the outer diameter of the tube body of the thick test tube. The second conveying gap 226 is arranged on the side of the first conveying gap 211 away from the push plate 221 to receive and convey the thick test tube. The second conveying gap 226 is located on the side of the first conveying gap 211 away from the push plate 221 and is arranged side by side with the first conveying gap 211, so that it is convenient to receive the thick test tube pushed out by the push plate 221. By setting the second conveying gap 226 smaller than the outer diameter of the tube cap of the thick test tube and larger than the outer diameter of the tube body of the thick test tube, when the thick test tube rolls onto the second conveying gap 226, the tube cap of the thick test tube can be supported on two second conveying gaps 226, so that the thick test tube can be placed upright for conveyance, which is convenient for the clamping claw 315 to clamp the thick test tube, facilitates the arrangement of the thick test tube, and improves the classification efficiency of the test tube.

[0047] It is understandable that the first conveying gap 211 and the second conveying gap 226 are arranged side by side, and the first conveying gap 211 and the second conveying gap 226 can be composed of three conveying belts arranged at intervals, or can be composed of three conveying tracks arranged at intervals. When the first conveying gap 211 and the second conveying gap 226 are composed of three conveying belts or conveying tracks, the middle conveying belt or conveying track is shared by the first conveying gap 211 and the second conveying gap 226.

[0048] Of course, the first conveying gap 211 and the second conveying gap 226 may also be composed of four conveying belts or conveying tracks that are arranged at intervals.

[0049] Further, see Figure 6 and Figure 8 A second lifting seat 342 is disposed below the second conveying gap 226, and the second lifting seat 342 is connected to a fifth driving member 341. The fifth driving member 341 drives the second lifting seat 342 to rise, so that the second lifting seat 342 can support the thick test tube and drive the test tube to extend out of the second conveying gap 226, so that the clamping claw 315 can clamp the thick test tube and improve the success rate of clamping the test tube. The fifth driving member 341 can be a linear cylinder or an electric push rod, which is not limited here.

[0050] Specifically, refer to Figure 1 , Figure 5 and Figure 7The second classification component 220 further includes a guide hopper 227 and a storage tank 228. The guide hopper 227 is arranged on the side of the first conveying gap 211 away from the push plate 221, and the storage tank 228 is arranged below the guide hopper 227 to receive the thick test tube. The guide hopper 227 is arranged on the side of the first conveying gap 211 away from the push plate 221. The push plate 221 drives the thick test tube to slide out of the first conveying gap 211 so that the thick test tube can slide into the guide hopper 227. The guide hopper 227 can guide the movement direction of the thick test tube so that the test tube can be concentrated in the storage tank 228, thereby facilitating the collection and sorting of the thick test tube and improving the sorting efficiency of the test tube.

[0051] It should be noted that the storage tanks 228 can be provided in plurality, so that when one of the storage tanks 228 is full, another storage tank 228 can be quickly replaced under the guide hopper 227, thereby achieving continuous sorting of the test tubes without shutting down the device.

[0052] It is understandable that, referring to Figure 1 and Figure 3 The fixed plate 122 is connected to a friction member 124 on one side close to the movable plate 123, and the test tube can roll on the friction member 124. The fixed plate 122 is connected to a friction member 124 on one side close to the movable plate 123, so that when the movable plate 123 drives the test tube to move on the wall of the fixed plate 122, the test tube can abut against the friction member 124, thereby increasing the movement resistance of the test tube, so that the test tube can roll smoothly on the friction member 124, and then the barcode stuck on the side wall of the test tube can be easily moved, so that the barcode scanner 130 can easily identify the barcode of the test tube.

[0053] It should be noted that the friction member 124 can be a rubber strip or a silicone strip. By setting a plurality of rubber strips and arranging them at intervals on the fixed plate 122, the test tube can roll smoothly on the rubber strip, thereby making it convenient to adjust the position of the test tube and facilitate the scanner 130 to identify the barcode on the test tube.

[0054] It is understandable that, referring to Figure 1, a partition 111 is connected to the middle of the silo 110, and the partition 111 divides the silo 110 into a first chamber 112 and a second chamber 113. A gap is provided between the partition 111 and the bottom wall of the silo 110, so that the first chamber 112 and the second chamber 113 are communicated, and the conveying assembly 120 is arranged in the first chamber 112. The partition 111 is connected to the middle of the silo 110, and the silo 110 is divided into the first chamber 112 and the second chamber 113 by the partition 111, and the first chamber 112 and the second chamber 113 are communicated. The test tube is put into the second chamber 113, so that the test tube can enter the first chamber 112 through the gap, and then the test tube is driven to be output one by one by the conveying assembly 120, so that the test tube put in first can be output first, so as to avoid the test tubes at the bottom of the silo 110 from being piled up, and improve the smoothness of the test tube transportation.

[0055] It is understandable that, referring to Figure 1 , Figure 4 and Fig. 9 The classification mechanism 200 also includes a rejection component 230, which includes a second conveyor belt 231, a rotating wheel 232, a third driving member 233 and a sensor 234. The second conveyor belt 231 is arranged between the fixed plate 122 and the first conveying gap 211, and the rotating wheel 232 is arranged at the output end of the second conveyor belt 231. The rotating wheel 232 is surrounded by a plurality of grooves 235 for accommodating test tubes. The third driving member 233 is used to drive the rotating wheel 232 to rotate, and the sensor 234 is used to sense the position of the test tube. The second conveyor belt 231 is arranged between the fixed plate 122 and the first conveying gap 211. The second conveyor belt 231 receives the test tube output by the fixed plate 122 and drives the test tube to be transported so that the test tube can enter the groove 235. The sensor 234 is arranged above the second conveyor belt 231. The position of the test tube is sensed by the sensor 234, and then the third driving member 233 drives the rotating wheel 232 to rotate, so that the rotating wheel 232 can rotate the test tube out of the second conveyor belt 231, so that the test tube can be removed without manual sorting, thereby improving the sorting efficiency.

[0056] It should be noted that the barcode pasted on the side wall of the test tube may be damaged or fall off during the transportation process, resulting in the scanner 130 being unable to recognize the barcode, and the test tubes with unrecognizable barcodes need to be sorted out for manual processing. When the barcode of the test tube is complete, the third drive member 233 stops, and the test tube can be driven by the second conveyor belt 231 to pass through the groove 235; when the barcode of the test tube is invalid, the third drive member 233 drives the rotating wheel 232 to rotate to drive the test tube in the groove 235 to disengage from the second conveyor belt 231, so that the test tubes with invalid barcodes can be automatically sorted out, thereby improving the sorting efficiency of the test tubes.

[0057] It is understandable that the rejection component 230 can be connected to the second classification component 220 so that the rejected unrecognizable test tubes can be collected along the guide hopper 227 into the storage tank 228 so that the operator can process them in a centralized manner.

[0058] It is understandable that, referring to Figure 1 and Figure 3 The conveying components 120 and the barcode scanner 130 are provided in multiple groups, and the multiple groups of conveying components 120 and the barcode scanner 130 are arranged side by side. By arranging the multiple groups of conveying components 120 and the barcode scanner 130 to be arranged side by side, multiple test tubes can be driven to rise at the same time, thereby improving the conveying efficiency and identification efficiency of the test tubes, reducing labor intensity, and improving efficiency.

[0059] Among them, the conveying components 120 and the barcode scanners 130 can be set to three groups or four groups, so that the silo 110 can cover multiple groups of conveying components 120 at the same time, thereby improving the recognition efficiency of the test tubes.

[0060] It is understandable that, referring to Figure 1 The fully automatic sample processing system of the second embodiment of the utility model includes the test tube feeding device of the first embodiment of the utility model. Since it has all the technical features of the embodiments of the utility model, it also has the beneficial effects of all the above embodiments, which will not be repeated here.

[0061] It should be noted that the fully automatic sample processing system includes the test tube feeding device of the first aspect of the utility model embodiment, which drives the test tubes to be output one by one through the conveying component 120, and the scanner 130 identifies the barcodes of the test tubes. Then the first classification component 210 and the second classification component 220 separate the thin test tubes and the thick test tubes, and transfer the test tubes through the gripper component 310 and the transfer component 320, so as to facilitate subsequent processing of the test tubes, such as centrifugation, sampling, recovery and other processes, thereby realizing automatic processing of the test tubes and improving efficiency.

[0062] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
