[0003] Existing sample transmission devices can only achieve the function of pipeline transmission of sample tubes. When there are samples to be discarded in the sample transmission device, the sample tubes need to be transmitted to a separately provided sample discarding device, resulting in a relatively large volume of the entire sample pipeline analysis system, occupying more space, and increasing the layout difficulty of the sample pipeline analysis system.

[0004] Therefore, how to reduce the layout difficulty of the sample pipeline analysis system is a technical problem that those skilled in the art need to solve currently. Summary of the Invention

When the central controller receives a sample output instruction, it controls the sample tube transfer mechanism to transfer the sample tube indicated by the sample output instruction to a preset position, realizing the function of distributing the sample tubes. The empty sample carrier from which the sample tube has been transferred enters the second transfer track arranged in parallel with the first transfer track through the first steering transfer mechanism, and the second transfer track receives and caches the empty sample carrier. When the central controller receives a sample insertion instruction, it controls the empty sample carrier on the second transfer track to enter the first transfer track through the second steering transfer mechanism, and controls the sample tube transfer mechanism to transfer the sample tube to be inserted into the empty sample carrier on the first transfer track, realizing the reception of the inserted sample tube, and conveying the inserted sample tube through the first transfer track.

Detailed implementation manners

[0031] In view of this, the core of the present invention lies in providing a sample tube transmission system to reduce the layout difficulty of the sample pipeline analysis system.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 2 shown, the embodiment of the present invention discloses a sample tube transmission system, including a first transmission track 100, a second transmission track 200, a first turning transmission mechanism 300, a second turning transmission mechanism 400, a sample tube transfer mechanism, a sample waste mechanism 500, and a central controller.

[0034] Among them, the first transfer track 100 is used to receive and convey a sample carrier loaded with a sample tube to facilitate the conveyance of the sample tube; the second transfer track 200 is used to receive and cache empty sample carriers, and the second transfer track 200 is arranged in parallel with the first transfer track 100; the first steering transfer mechanism 300 is used to transfer the empty sample carrier on the first transfer track 100 to the second transfer track 200; the second steering transfer mechanism 400 is used to transfer the empty sample carrier on the second transfer track 200 to the first transfer track 100; the sample tube transfer mechanism is used to grab and transfer the sample tube; the sample waste mechanism 500 is used to receive and store the discarded sample tubes; after receiving the sample output instruction, the central controller can control the sample tube transfer mechanism to transfer the sample tube indicated by the sample output instruction to a preset position; after receiving the sample insertion instruction, the central controller can control the empty sample carrier on the second transfer track 200 to enter the first transfer track 100 through the second steering transfer mechanism 400, and control the sample tube transfer mechanism to transfer the sample tube to be inserted into the empty sample carrier on the first transfer track 100; after receiving the sample waste instruction, the central controller can control the sample transfer mechanism to move the sample tube indicated by the sample waste instruction into the sample waste mechanism 500.

[0035] When using the sample tube transfer system provided by the present invention, the first transfer track 100 receives and conveys a sample carrier loaded with a sample tube, thereby realizing the conveyance function of the sample tube; when the central controller receives the sample output instruction, it controls the sample tube transfer mechanism to transfer the sample tube indicated by the sample output instruction to a preset position, realizing the distribution function of the sample tube. The empty sample carrier from which the sample tube has been transferred enters the second transfer track 200 arranged in parallel with the first transfer track 100 through the first steering transfer mechanism 300, and the second transfer track 200 receives and caches the empty sample carrier; when the central controller receives the sample insertion instruction, it controls the empty sample carrier on the second transfer track 200 to enter the first transfer track 100 through the second steering transfer mechanism 400, and controls the sample tube transfer mechanism to transfer the sample tube to be inserted into the empty sample carrier on the first transfer track 100, realizing the reception of the inserted sample tube and conveying the inserted sample tube through the first transfer track 100; when the central controller receives the sample waste instruction, it controls the sample transfer mechanism to move the sample tube indicated by the sample waste instruction into the sample waste mechanism 500, and the sample waste mechanism 500 receives and stores the discarded sample tube. It can be seen that the sample tube transfer system provided by the present invention not only integrates the functions of sample tube transfer, caching empty sample carriers, inserting and transferring sample tubes, but also integrates the function of discarding sample tubes, thereby reducing the volume of the entire sample pipeline analysis system, reducing the occupied space, and reducing the layout difficulty of the sample pipeline analysis system.

[0036] It should be noted that the above description of the working process of the central controller only reflects the control function of the central controller. This application does not involve improvements in programs and control methods, and the control method of the above central controller belongs to the prior art.

[0037] In addition, both the first transfer track 100 and the second transfer track 200 described above can adopt transmission types such as synchronous belt transmission, flat belt transmission, roller transmission, or chain drive. As long as the transmission type can meet the transmission requirements, it belongs to the protection scope of the present invention; preferably, both the first transfer track 100 and the second transfer track 200 provided in the embodiments of the present invention adopt synchronous belt transmission to make the sample tube transmission system have a more accurate transmission ratio.

[0038] Moreover, the present invention does not limit the specific quantity, specific length, and setting method of the first transfer track 100 and the second transfer track 200. A plurality of first transfer tracks 100 and a plurality of second transfer tracks 200 can be arranged in one-to-one correspondence and at intervals, or to increase the buffer capacity of the empty sample holders, the first transfer track 100 corresponds to a plurality of second transfer tracks 200. As long as the quantity and setting method can meet the usage requirements, they belong to the protection scope of the present invention; preferably, the quantity of both the first transfer track 100 and the second transfer track 200 of the sample tube transmission system provided in the embodiments of the present invention is one.

[0039] Furthermore, the sample waste disposal mechanism 500 includes at least one waste disposal component 501, that is, the sample tube transmission system includes at least one waste disposal position. The waste disposal component 501 includes a receiving tube 5011 arranged between the first transfer track 100 and the second transfer track 200, a diversion groove 5012 communicated with the receiving tube 5011, and a waste bin 5013 communicated with the diversion groove 5012. And the diversion groove 5012 is located below the receiving tube 5011, and the waste bin 5013 is located below the diversion groove 5012. The receiving tube 5011 can receive the sample tube. So that after the sample transfer mechanism places the sample tube to be discarded at the waste disposal position, the receiving tube 5011 receives the sample tube to be discarded. The sample tube to be discarded enters the diversion groove 5012 located below the receiving tube 5011 under the action of its own weight, and then falls into the waste bin 5013 located below the diversion groove 5012, completing the discarding and collection of the sample tube to be discarded.

[0040] It should be noted that the number of the above-mentioned waste components 501 can be one, two or multiple, etc. In practical applications, the number of waste components 501 can be adaptively adjusted according to actual requirements, and any number that can meet the usage requirements belongs to the protection scope of the present invention; preferably, the number of waste components 501 provided in the embodiment of the present invention is two, that is, the sample tube transmission system includes two waste positions, so as to increase the capacity of the waste sample tubes that the sample tube transmission system can accommodate.

[0041] As Figure 2 shown, the waste component 501 further includes a garbage bag and a pressing plate 5014. The garbage bag is sleeved inside the waste bin 5013 to facilitate the collection of waste sample tubes. The pressing plate 5014 is used to press the garbage bag in the waste bin 5013 to prevent the capacity of the waste sample tubes from being reduced due to the protrusion of the garbage bag, and at the same time prevent the opposed sensor 5015 described below from misdetecting the protruding garbage bag as a full waste sample tube.

[0042] In addition, the waste component 501 further includes an opposed sensor 5015 disposed on the upper side of the waste bin 5013 and a reflector 5016 that can cooperate with the opposed sensor 5015, so as to detect whether the waste sample tubes in the waste bin 5013 are full through the opposed sensor 5015 and the reflector 5016, so as to clean the waste bin 5013 in time and prevent the waste sample tubes from overflowing from the waste bin 5013.

[0043] Further, the first transfer track 100 includes a first motor, a first driving wheel, a first driven wheel, a first synchronous belt 101 and a first guiding track 102. The first driving wheel is disposed on the output shaft of the first motor to drive the first driving wheel to rotate through the first motor; the first driven wheel cooperates with the first driving wheel, and the first synchronous belt 101 connects the first driving wheel and the first driven wheel to enable the first synchronous belt 101 to rotate in a closed loop between the first driving wheel and the first driven wheel; the sample tray on which the sample tube is placed is located on the first synchronous belt 101 to drive the transmission of the sample tray through the first synchronous belt 101, thereby transmitting the sample tube; and the sample tray is slidably connected to the first guiding track 102 to guide the transmission direction of the sample tube.

[0044] In addition, the first transfer track 100 further includes a first in-place sensor 103 and a first blocking member 104 disposed at the entrance of the first transfer track 100. When the central control system receives a sample input instruction and the first in-place sensor 103 detects that the sample tray on which the sample tube is placed is in place, that is, when the sample tube reaches the entrance position of the first transfer track 100, the central control system controls the first blocking member 104 to open, so as to convey the sample tube into the first transfer track 100 for subsequent sample tube conveying and distribution.

[0045] In addition, the first transfer track 100 further includes an information identifier 105 and a sample rotator 106. The information identifier 105 and the sample rotator 106 are arranged at the sample tube picking and placing position of the sample tube transfer system, so as to first place the sample tube inserted through the sample tube transfer mechanism at the sample tube picking and placing position, and the information identifier 105 identifies the identity information of the sample tube.

[0046] Specifically, a sample tube label capable of displaying the identity information of the sample tube is provided on the sample tube, and a sample tray label capable of displaying the identity information of the sample tray is provided on the sample tray. The information identifier 105 can identify the sample tube label and the sample tray label and bind or unbind the identity information of the sample tube and the identity information of the sample tray, so as to transmit the bound information to the central controller. When transferring and distributing the sample tube subsequently, the sample tube and the sample tray can be accurately positioned, improving the accuracy of the sample tube transfer system; the sample rotator 106 is used to rotate the sample tray, so as to rotate the sample tube label and the sample tray label to face the information identifier 105, enabling the information identifier 105 to read the sample tube label and the sample tray label.

[0047] The structures of the first steering transfer mechanism 300 and the second steering transfer mechanism 400 provided by the present invention may be the same or different, as long as the structures that can meet the use requirements are within the protection scope of the present invention; preferably, the first steering transfer mechanism 300 and the second steering transfer mechanism 400 with the same structure are adopted in the embodiments of the present invention, so as to improve the versatility of parts and reduce the development cost of non-standard parts.

[0048] Specifically, the first steering transfer mechanism 300 includes a steering structure and a transfer structure. The steering structure is used to change the forward direction of the empty sample tray, so as to make the empty sample tray on the first transfer track 100 face the second transfer track 200. The transfer structure is used to convey the empty sample tray, so as to convey the empty sample tray to the second transfer track 200, thereby caching the empty sample tray through the second transfer track 200.

[0049] The above-mentioned steering structure may be a guide plate, a guide rod or a turntable and other types of structures. As long as the structure that can change the forward direction of the empty sample tray is within the protection scope of the present invention.

[0050] Similarly, the above-mentioned transfer structure may adopt a roller conveyor method, a chain conveyor or a belt conveyor and other methods. As long as the conveyor method that can convey the empty sample tray to the second transfer track 200 is within the protection scope of the present invention.

[0051] Since the structure of the second steering transfer mechanism 400 is the same as that of the first steering transfer mechanism 300, all the technical effects of the first steering transfer mechanism 300 are taken into account, and will not be elaborated one by one herein.

[0052] Furthermore, the second transfer track 200 includes a second motor, a second driving wheel, a second driven wheel, a second synchronous belt 201, and a second guiding track 202; the second driving wheel is arranged on the output shaft of the second motor so as to enable the second motor to drive the second driving wheel to rotate; the second driven wheel can cooperate with the second driving wheel, and the second synchronous belt 201 connects the second driving wheel and the second driven wheel so as to enable the second synchronous belt 201 to perform a closed-loop rotation between the second driving wheel and the second driven wheel; the empty sample carrier is above the second synchronous belt 201 so as to be driven by the second synchronous belt 201 to convey the empty sample carrier on the second transfer track 200; and the empty sample carrier is slidably connected to the second guiding track 202 so as to guide the movement of the empty sample carrier through the second guiding track 202 and improve the movement trajectory accuracy of the empty sample carrier.

[0053] The second transfer track 200 further includes a second in-place sensor 203 and a second blocking member 204 arranged at the end of the second guiding track 202. When the central control system receives a sample insertion instruction and the second in-place sensor 203 detects that the empty sample carrier is in place, the central control system controls the second blocking member 204 to open so as to enable the empty sample carrier to enter the first transfer track 100 and thus receive the sample tube to be inserted transferred by the sample tube transfer mechanism.

[0054] In addition, the second transfer track 200 further includes a full amount sensor 205 so as to detect whether the number of empty sample carriers on the second transfer track 200 reaches the capacity threshold, prevent the number of empty sample carriers from exceeding the capacity threshold of the second transfer track 200, causing accumulation of empty sample carriers and affecting the normal operation of the sample tube transfer system.

[0055] The capacity threshold of the second transfer track 200 is related to the length and quantity of the second transfer track 200. Therefore, the present invention does not specifically limit the capacity threshold of the second transfer track 200, and in practical applications, the capacity threshold of the second transfer track 200 can be adaptively adjusted according to actual situations, that is, the buffer capacity of the second transfer track 200 is adaptively adjusted.

[0056] In addition, the present invention also discloses a sample pipeline analysis system, including the sample tube transfer system described in any one of the above, and thus has all the technical effects of the above sample tube transfer system, which will not be elaborated one by one herein.

[0057] In the description and claims of the present invention and the above-mentioned drawings, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units not listed.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
