Description

Furthermore, this utility model also provides an automated medical laboratory production line including the aforementioned sample tray changing track device. Background Technology

[0002] Existing high-throughput automated medical laboratory systems typically employ a three-track design: an injection track, a return track, and a buffer track. After samples such as blood collection tubes are loaded into the sample holder, the sample holder enters the injection track and runs on it. When sample buffering is required, the sample holder changes track to the buffer track.

[0003] The currently common method for sample trajectory changing is to use a buffered commutation component in conjunction with the commutation component to drive the sample carrier, such as... Figure 1 As shown, its rotating dial mechanism can cooperate with the rotating block mechanism to enable the sample holder to change tracks bidirectionally between the sample inlet track and the buffer track. Both the dial mechanism and the block mechanism are rotating mechanisms, which require dual motor drive, resulting in a complex structure, high cost, and relatively complex action logic.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of the utility model.

[0032] The core of the utility model provides a kind of sample tray variable orbit device, simple structure, equipment cost is lower, it is also effectively optimized the action logic of sample tray variable orbit, convenient and fast.

[0033] In addition, the utility model further provides a kind of medical laboratory automation assembly line comprising sample tray variable orbit mechanism.

[0034] The sample tray variable orbit device provided by the utility model, including the reversing disc 1 rotationally arranged between the sample inlet track 10 and the buffer track 20 and the reversing power assembly for driving the reversing disc 1 to rotate, the reversing disc 1 is fan-shaped, and one end of the reversing disc 1 is provided with a reversing groove 11 for cooperating with the sample tray 40 to drive the sample tray 40 to rotate;

[0035] When the reversing disc 1 is in the working position, one end of the reversing disc 1 cooperates with the partition plate to separate the sample inlet track 10 and the buffer track 20;

[0036] When the reversing disc 1 is in the pre-variable orbit position, the reversing disc 1 blocks the sample inlet track 10, and the orientation of the reversing groove 11 is opposite to the sample inlet direction of the sample inlet track 10, so that the sample tray 40 enters the reversing groove 11 along the sample inlet direction;

[0037] When the reversing disc 1 is in the variable orbit position, the reversing groove 11 is aligned with the buffer direction of the buffer track 20, so that the sample tray 40 is separated from the reversing groove 11.

[0038] Please refer to Figure 2 , a partition plate is arranged between the sample inlet track 10 and the buffer track 20 to separate the sample inlet track 10 and the buffer track 20, and the reversing disc 1 is arranged at the gap of the partition plate, and the end face of one end of the reversing disc 1 without the reversing groove 11 is usually arranged as a vertical surface perpendicular to the track surface, so that the reversing disc 1 can cooperate with the partition plate when in the working position;

[0039] The reversing disc 1 is fan-shaped, one end of the reversing disc 1 is provided with the reversing groove 11, after the sample tray 40 contacts the reversing groove 11 in the pre-variable orbit position, the reversing disc 1 drives the sample tray 40 to rotate to the variable orbit position through the reversing groove 11, at this time, the orientation of the reversing groove 11 is opposite to the movement direction of the sample tray 40, so that the sample tray 40 can smoothly separate from the reversing groove 11 after variable orbit.

[0040] The shape of the reversing groove 11 is adapted to the shape of the sample holder 40 so that the reversing groove 11 can effectively fit with the outer peripheral surface of the sample holder 40, thereby using the contact between the two to drive the rotation and track change of the sample holder 40; considering that the cross-sectional shape of the sample holder 40 is usually circular, the reversing groove 11 is preferably set as an arc groove. It should be noted that the arc groove here includes a semi-circular groove, and the inner diameter of the arc groove is the same as the outer diameter of the sample holder 40, or the inner diameter of the arc groove is slightly larger than the outer diameter of the sample holder 40.

[0041] In this embodiment, the sample tray changing device uses a reversing disk 1 and a partition to separate the sample inlet track 10 and the buffer track 20 to ensure the normal operation of the sample inlet track 10 and the buffer track 20. When a change of track is required, the sample tray 40 is driven from the sample inlet track 10 into the buffer track 20 by the rotation of the reversing disk 1. Compared with the prior art, the design of the single rotation mechanism not only simplifies the structure of the sample tray changing device and reduces the equipment cost, but also effectively optimizes the action logic of the sample tray 40 changing track, making it convenient and quick.

[0042] Based on the above embodiments, the structure of the commutator 1 is defined as follows: the central angle of the commutator 1 refers to the angle between the line connecting the openings of the commutator slot 11 and the plane containing the other end of the commutator 1; the central angle α of the commutator 1 is less than 180°; the diameter of the commutator 1 is less than or equal to the width of the sample feed track 10; and the diameter of the commutator 1 is less than or equal to the width of the buffer track 20.

[0043] The central angle α of the reversing disk 1 is less than 180°, so as to prevent part of the reversing disk 1 from protruding into the sample inlet track 10 when it is in the working position, thus occupying the space of the sample inlet track 10 and affecting the normal operation of the sample inlet track 10. It can also achieve the narrowest width and the highest space utilization rate of the sample inlet track 10 while keeping the size of the sample holder 40 unchanged.

[0044] The phase difference between the pre-change position and the change position is determined according to the angle α of the central angle of the commutator 1. When the commutator 1 is in the pre-change position, the commutator 1 is in the change position when the commutator power assembly drives the commutator 1 to rotate α.

[0045] The diameter of the reversing disk 1 is less than or equal to the width of the sample inlet track 10 to avoid the reversing disk 1 from rubbing against the partitions on both sides of the sample inlet track 10 during rotation, affecting the rotation control accuracy of the reversing disk 1, which would cause the reversing disk 1 to fail to rotate accurately to the pre-change track position, so that the sample holder 40 cannot enter the reversing groove 11.

[0046] Meanwhile, the diameter of the reversing disk 1 is less than or equal to the width of the buffer track 20 to prevent the reversing disk 1 from rubbing against the partitions on both sides of the buffer track 20 during rotation, which would affect the rotation control accuracy of the reversing disk 1 and thus prevent the sample holder 40 from accurately moving to the change track position, thereby affecting the sample holder 40 from disengaging from the reversing groove 11.

[0047] On the basis of the above-mentioned embodiments, in order to ensure that the sample holder 40 accurately enters and leaves the reversing groove 11, the phase difference between the working position of the reversing disc 1 and the pre-rail-changing position of the reversing disc 1 is 90°, and the phase difference between the pre-rail-changing position of the reversing disc 1 and the rail-changing position of the reversing disc 1 is 150°.

[0048] Please refer to Figures 3-5 When the reversing disc 1 is located at the working position, one end of the reversing disc 1 is a vertical surface perpendicular to the rail surface, the vertical surface of the reversing disc 1 is flush with the partition plate, and the reversing disc 1 cooperates with the partition plate to separate the sample rail 10 and the buffer rail 20, as shown in Figure 3 ;

[0049] When the rail changing of the sample holder 40 needs to be performed, first, the reversing power assembly is controlled to drive the reversing disc 1 to rotate clockwise by 90° to the pre-rail-changing position, as shown in Figure 4 At this time, the vertical surface of the reversing disc 1 is perpendicular to the partition plate, the axis of the reversing groove 11 of the reversing disc 1 coincides with the axial center line of the sample rail 10, and the opening direction of the reversing groove 11 is opposite to the sample direction, which facilitates the smooth entry of the sample holder 40 into the reversing groove 11 and ensures the contact area between the reversing groove 11 and the sample holder 40.

[0050] Then, the reversing power assembly is controlled to drive the reversing disc 1 to rotate clockwise by 150° to the rail-changing position, as shown in Figure 5 At this time, the axis of the reversing groove 11 of the reversing disc 1 coincides with the axial center line of the buffer rail 20, and the opening direction of the reversing groove 11 is the same as the buffer direction, which facilitates the smooth leaving of the sample holder 40 from the reversing groove 11.

[0051] On the basis of the above-mentioned embodiments, the reversing power assembly includes a reversing motor 4, the motor shaft of the reversing motor 4 is connected with the reversing disc 1 through a connecting part, and the motor shaft, the connecting part and the reversing disc 1 are collinear.

[0054] On the basis of the above-mentioned embodiments, in order to facilitate detection of whether the reversing disc 1 is reset to the working position after completing the orbit change, a home position detection assembly for detecting whether the reversing disc 1 returns to the working position is further included, the home position detection assembly includes a home position sensor 5, one of the receiver and the transmitter of the home position sensor 5 is installed on the fixed part of the reversing motor 4 through a home position bracket, and the other is arranged on the outer peripheral part of the connecting part.

[0055] Therefore, the receiver of the home position sensor 5 can detect and determine the orientation of the connecting part by receiving the output signal of the transmitter, and further determine the orientation of the reversing disc 1;

[0056] The home position sensor 5 can be specifically set as a proximity sensor such as a photoelectric switch, as shown in Figure 2 The home position sensor detection sheet 51 and the corresponding transmitter shown in the figure can also be an orientation sensor such as an encoder for detecting the rotation angle of the connecting part.

[0057] Preferably, in order to facilitate detection of whether the reversing disc 1 is accurately positioned during the orbit change operation, the sample tray orbit change device can further include a position detection assembly for detecting whether the reversing disc 1 is positioned in the pre-orbit change position and the orbit change position, the position detection assembly includes a position sensor 6, one of the receiver and the transmitter of the position sensor 6 is installed on the fixed part of the reversing motor 4 through a position bracket, and the other is arranged on the outer peripheral part of the connecting part.
