Referring to fig. 1, 7 and 8, the present invention provides a sample cup transport apparatus 100. The sample cup transfer device 100 is applied to a coagulation analyzer for transferring a sample cup 200. The sample cup transfer device 100 can transfer the sample cup 200 to the unloading position, and the sample cup 200 is transferred by the transfer device 300 of the coagulation analyzer, so that the coagulation analyzer can detect the sample. In general, the sample cup 200 for detecting a sample in a coagulation analyzer includes a positioning flange and a cup body, the cup body is used for containing the magnetic beads 210, and the positioning flange is used for supporting the sample cup 200. The sample cup conveying device 100 of the present invention can realize reliable conveyance of the sample cup 200, prevent the magnetic beads 210 in the sample cup 200 from falling out, and at the same time, can improve the conveying speed of the sample cup 200 and improve the detection efficiency.

Referring to fig. 1 to 5, in an embodiment, the sample cup conveying device 100 includes a sample cup feeding mechanism 110, a sample cup carrying mechanism 120, and a sample cup conveying mechanism 130. The sample cup feeding mechanism 110 is used to convey the sample cups 200. The sample cup carrier 120 is used for receiving the sample cup 200 in the sample cup feeding mechanism 110 and transporting the sample cup 200 to the coagulation analyzer. The sample cup conveying mechanism 130 is a power source for conveying the sample cups 200, and can drive the sample cup carrying mechanism 120 to move, so that the sample cup feeding mechanism 110 conveys the empty sample cups 200 to the loading position, and returns the empty sample cups to the sample storage mechanism from the loading position to take next sample cups 200.

Specifically, the cuvette feed mechanism 110 is configured to supply the cuvette 200, on which the magnetic bead 210 is placed, to the loading position. The sample cup carrying mechanism 120 comprises a feeding block 121 for carrying the sample cup 200 and a magnetic member 122 arranged on the feeding block 121, the feeding block 121 is provided with a carrying cavity 1221, the carrying cavity 1221 is used for receiving the sample cup 200 fed by the sample cup feeding mechanism 110 at the loading position, and the magnetic member 122 is used for attracting the magnetic beads 210 of the sample cup 200 in the carrying cavity 1221. The sample cup transport mechanism 130 is connected to the sample cup carrying mechanism 120 for moving the sample cup carrying mechanism 120 between the loading position and the unloading position to transport the sample cup 200 from the loading position to the unloading position.

Here, the loading position refers to a position at which the sample cup feeding mechanism 110 feeds out the sample cup 200, as shown by the position of the feed block 121 in fig. 1, and the unloading position refers to a position at which the transfer device 300 receives the sample cup 200 from the sample cup carrying mechanism 120, as shown by the position of the feed block 121 in fig. 5. In this way, after the sample cup carrying mechanism 120 moves to the loading position, the sample cup feeding mechanism 110 conveys the sample cup 200 into the sample cup carrying mechanism 120, and then the sample cup conveying mechanism 130 drives the sample cup carrying mechanism 120 to move, so that the sample cup carrying mechanism 120 moves from the loading position to the unloading position, and the sample cup 200 in the sample cup carrying mechanism 120 is transferred by the transfer device 300 of the coagulation analyzer at the unloading position. Subsequently, the sample cup 200 carrier is unloaded back to the loading position and the next sample cup 200 is transported.

And, sample cup bearing mechanism 120 realizes the reliable transport of sample cup 200 through the cooperation of pay-off piece 121 and magnetic part 122. Specifically, the sample cup conveying mechanism 130 can drive the feeding block 121 to move between the loading position and the unloading position, and the feeding block 121 is provided with a bearing cavity 1221 for bearing the sample cup 200. After the sample cup conveying mechanism 130 drives the feeding block 121 to move to the loading position, the bearing cavity 1221 corresponds to the sample cup feeding mechanism 110, and the sample cup feeding mechanism 110 can feed the sample cup 200 into the bearing cavity 1221. It is understood that the sample cup feeding mechanism 110 may adopt a cup grabbing or cup pushing manner to feed the sample cup 200 to the sample cup carrying mechanism 120, which will be described in detail later. After the sample cup conveying mechanism 130 drives the feeding block 121 for loading the sample cups 200 to move from the loading position to the unloading position, the carrying cavity 1221 corresponds to the transferring device 300 of the blood coagulation analyzer, and the transferring device 300 grabs the sample cups 200 in the feeding block 121 and transfers the sample cups to the next station, such as the sample incubation device 400. Subsequently, the sample cup transfer mechanism 130 drives the empty feeding block 121 from the unloading position to the loading position for the next process operation.

It can be understood that, since the bottom of the sample cup 200 is arc-shaped, the magnetic beads 210 may slide along the arc-shaped bottom of the sample cup 200 during the transportation process of the sample cup 200, and then fall out of the sample cup 200, which may affect the accurate detection of the sample. Based on this, in the sample cup conveying device 100 of the present application, the magnetic member 122 is added at the position of the feed block 121. After the sample cup feeding mechanism 110 feeds the sample cup 200 to the bearing cavity 1221 of the feed block 121, the magnetic member 122 in the feed block 121 may attract the magnetic beads 210 in the sample cup 200, so that the magnetic beads 210 are not easy to move. Like this, sample cup 200 is in the transportation, and the magnetic bead 210 in the sample cup 200 is difficult for the motion all the time, can not slide along the arc bottom of sample, and then avoids magnetic bead 210 to fall out sample cup 200, guarantees the accuracy of sample detection.

When the sample cup conveying device 100 conveys the sample cups 200, the transmission assembly 131 drives the feeding block 121 to move to the loading position, and the sample cup feeding mechanism 110 feeds the sample cups 200 with the magnetic beads 210 to the bearing cavity 1221 of the feeding block 121. At this time, the magnetic member 122 attracts the magnetic beads 210 in the sample cup 200, so that the magnetic beads 210 are not easily moved. Subsequently, the sample cup conveying mechanism 130 drives the feeding block 121 to move from the loading position to the unloading position through the transmission assembly 131, and the sample cup 200 in the feeding block 121 is transferred away through the transfer device 300 of the coagulation analyzer. After the sample cup 200 is unloaded, the sample cup conveying mechanism 130 drives the feeding block 121 to move from the unloading position to the loading position through the transmission assembly 131, so as to convey the next sample cup 200.

According to the sample cup conveying device 100, the magnetic member 122 is additionally arranged at the feeding block 121 to attract the magnetic beads 210 in the sample cup 200 in the bearing cavity 1221, so that the movement of the magnetic beads 210 in the sample cup 200 is limited, and the magnetic beads 210 are prevented from moving along the arc-shaped bottom of the sample cup 200. The magnetic bead 210 in the effectual solution sample cup 200 has the risk of falling out the rim of a cup along arc bottom motion, has prevented the emergence that magnetic bead 210 falls out the condition, avoids reporting the mistake because of the testing result that lacks magnetic bead 210 and leads to, promotes the detection accuracy. Meanwhile, after the magnetic beads 210 are limited by the magnetic part 122, the magnetic beads 210 are prevented from falling out of the cup opening under the condition that the conveying speed of the sample cup conveying mechanism 130 is increased, and the detection efficiency is improved.

In one embodiment, when the sample cup 200 is in the loading chamber 1221, the magnetic induction intensity generated by the magnetic member 122 on the magnetic bead 210 in the sample cup 200 is in a range of 40 mt to 50 mt. That is, the magnetic induction intensity of the magnetic material 122 with respect to the magnetic beads 210 ranges from 40 mt to 50 mt. Therefore, the attractive force generated by the magnetic member 122 on the magnetic bead 210 can be ensured to be reasonable, so that the magnetic bead 210 can be just attracted by the magnetic member 122 and cannot move, and the problem of insufficient or overlarge attractive force is avoided.

It can be understood that the magnetic member 122 may not attract the fixed magnetic beads 210 due to insufficient attraction of the magnetic member 122, and when the sample moving mechanism drives the feeding block 121 to move, the magnetic beads 210 in the sample cup 200 may slide along the arc-shaped bottom of the sample cup 200, so that there is a risk that the magnetic beads 210 fall out of the sample cup 200. If the attraction force of the magnetic member 122 is too large, the magnetic member 122 will attract the magnetic beads 210 in the sample cup 200 before the sample cup 200 enters the carrying cavity 1221 of the feeding block 121, the magnetic beads 210 are attracted to the inner wall of the sample cup 200 close to the feeding block 121, and the attraction force will pull the sample cup 200 to enter the carrying cavity 1221 of the feeding block 121 first, so that the phenomena of jamming, sample cup tilting and the like occur, which affects the transportation of the sample cup 200.

Therefore, the magnetic induction intensity of the magnetic member 122 is limited to ensure the attraction of the magnetic member 122 to the magnetic beads 210, so that the magnetic beads 210 are attracted by a proper attraction force, the loading of the sample cup 200 is facilitated, and the problem of clamping stagnation in the loading process of the sample cup 200 is avoided.

In one embodiment, there is a space between the magnetic member 122 and the sample cup 200 in the carrying chamber 1221. The magnetic member 122 is spaced from the sample cup 200 in the carrying cavity 1221, so that the magnetic induction intensity generated by the magnetic member 122 can be reduced, the attraction of the magnetic member 122 to the magnetic bead 210 can be further reduced, and the magnetic force generated by the magnetic member 122 is prevented from being too large. Further, the pitch ranges from 4mm to 5 mm. Like this, can guarantee that the magnetic induction intensity scope that magnetic part 122 produced is reasonable, and then guarantee that the size of appeal is reasonable, avoid excessively attracting magnetic bead 210.

In one embodiment, the feedblock 121 has a mounting cavity for mounting the magnetic member 122. It is understood that the magnetic member 122 may be completely installed in the installation cavity or partially installed in the installation cavity. Illustratively, the magnetic member 122 is mounted entirely within the mounting cavity. Therefore, in the process that the feeding block 121 drives the magnetic part 122 to move, the magnetic part 122 can be prevented from interfering with other parts, and the stable operation is ensured. Of course, in other embodiments of the present invention, the magnetic member 122 may be directly mounted on the surface of the feeding block 121 as long as the magnetic member 122 can attract the magnetic beads 210 in the supporting cavity 1221.

In one embodiment, the magnetic member 122 is fixed to the feedblock 121 by gluing or screws 123. Therefore, the magnetic piece 122 can be reliably fixed on the feeding block 121, the magnetic piece 122 is prevented from dropping in the moving process of the feeding block 121, and the magnetic beads 210 in the sample cup 200 are ensured to be fixed reliably. Of course, in other embodiments of the present invention, the magnetic member 122 may also be fixed to the feeding block 121 by clamping or the like. Illustratively, the magnetic member 122 is fixed to the feeding block 121 by a screw 123, preventing the magnetic member 122 from falling.

Optionally, the shape of the magnetic member 122 is adapted to the shape of the mounting cavity to facilitate mounting of the magnetic member 122. Illustratively, the magnetic member 122 may be cylindrical, spherical, hexahedral, or the like.

In one embodiment, the mounting cavity is separate from the bearing cavity 1221. That is, the mounting cavity and the bearing cavity 1221 are independent and not communicated with each other. Like this, the feedblock 121 part that exists between installation cavity and the bearing chamber 1221 can block partial magnetic line of force to weaken magnetic induction, and then make magnetic induction reasonable, guarantee the accurate magnetic bead 210 that attracts of magnetic part 122.

In one embodiment, the bearing chamber 1221 is located at the top of the feeding block 121 on the side facing the sample cup feeding mechanism 110, and is disposed through the side facing the sample cup feeding mechanism 110 to receive the sample cup 200 supplied from the sample cup feeding mechanism 110, and the magnetic member 122 is located on the peripheral side of the bearing chamber 1221, or the magnetic member 122 is located at the bottom of the bearing chamber 1221. That is, the bearing cavity 1221 has a notch at the top of the feeding block 121, and the notch faces to one side of the sample cup feeding mechanism 110, so as to facilitate the sample cup feeding mechanism 110 to feed the sample cup 200. The magnetic member 122 is located on the side wall of the bearing chamber 1221, or the magnetic member 122 is located on the bottom of the bearing chamber 1221. After the sample cup 200 is located in the supporting cavity 1221, the magnetic member 122 can directly attract the magnetic beads 210 in the sample cup 200, so that the magnetic beads 210 in the sample cup 200 can be immobilized. Illustratively, the magnetic member 122 is located on the peripheral side of the bearing chamber 1221, and further, the magnetic member 122 is located on the side of the bearing chamber 1221 away from the sample cup feeding mechanism 110.

It can be understood that the shape of the supporting cavity 1221 is matched with the shape of the sample cup 200, and a proper gap is left when the sample cup 200 is placed in the supporting cavity 1221, so as to ensure that the sample cup 200 is reliably placed in the supporting cavity 1221, and meanwhile, the sample cup 200 is convenient to mount and dismount.

In one embodiment, the sample cup conveying mechanism 130 includes a transmission assembly 131 and a blocking plate 132, and the transmission assembly 131 is connected to the feeding block 121 and is used for driving the feeding block 121 to move. The driving assembly 131 can drive the feeding block 121 to move between the loading position and the unloading position. After the feeding block 121 carries the sample cup 200 fed by the sample cup feeding mechanism 110 at the loading position, the transmission assembly 131 drives the feeding block 121 to move from the loading position to the unloading position, then the sample cup 200 in the feeding block 121 is grabbed and transferred by the transfer device 300 of the blood coagulation analyzer, and then the transmission assembly 131 drives the feeding block 121 to return to the loading position from the unloading position for carrying out loading and conveying of the next sample cup 200.

The blocking plate 132 extends along the transmission path of the transmission assembly 131, and is located on one side of the feeding block 121 facing the sample cup feeding mechanism 110, and is used for limiting the sample cups 200 in the bearing cavities 1221 during transportation. The blocking plate 132 serves to define the sample cup 200 within the carrier chamber 1221. Due to the fact that the bearing cavity 1221 is of a notch structure, the sample cup 200 may fall off the bearing cavity 1221 during the process of conveying the sample cup 200 by the feed block 121. After the blocking plate 132 is arranged, the blocking plate 132 is located at the notch of the bearing cavity 1221 and encloses into a limiting cavity with other three side walls of the bearing cavity 1221, so that the sample cup 200 is reliably located in the bearing cavity 1221, the sample cup 200 is prevented from being separated from the bearing cavity 1221, and the sample cup 200 is ensured to be reliably transported.

Meanwhile, due to the attraction effect of the magnetic member 122, the magnetic bead 210 is attracted to the inner wall of the sample cup 200 by the magnetic member 122, and the sample cup 200 is driven by the magnetic bead 210 to be close to the magnetic member 122 as much as possible. That is, after the magnetic member 122 attracts the magnetic beads 210, the outer wall of the sample cup 200 sandwiched therebetween can be tightly attached to the inner wall of the bearing chamber 1221, so as to position the sample cup 200. Therefore, a gap is kept between the blocking plate 132 and the sample cup 200, the sample cup 200 and the blocking plate 132 are prevented from generating fragments due to friction, the sample cup 200 is reliably conveyed, the detection accuracy is improved, and the maintenance cost is reduced.

Alternatively, the transmission assembly 131 includes, but is not limited to, a rack and pinion transmission assembly, a chain sprocket transmission assembly, a synchronous belt transmission assembly, or a ball screw assembly, and may be other structures capable of realizing the motion driving of the feeding block 121.

Further, the sample cup conveying mechanism 130 further comprises a guide assembly 133, and the guide assembly 133 is used for guiding the movement of the feeding block 121, so that the feeding block 121 runs along a fixed path, and the feeding block 121 is ensured to move stably and reliably. Alternatively, the guiding assembly 133 includes, but is not limited to, a sliding rail assembly, and the like, and may be other structures capable of guiding.

In one embodiment, when the sample cup 200 is located in the loading chamber 1221, the magnetic member 122 at least partially corresponds to the magnetic beads 210 (usually located at the bottom of the cup). That is, the magnetic member 122 may be partially disposed away from the magnetic beads 210, or may be disposed opposite to the magnetic beads 210. This may facilitate the magnetic member 122 to attract the magnetic beads 210. Illustratively, when the sample cup 200 is located in the loading chamber 1221, the magnetic member 122 faces the magnetic beads 210 at the bottom of the cup.

In one embodiment, the magnetic member 122 includes a permanent magnet or an electromagnet.

Optionally, the magnetic member 122 includes a permanent magnet, and after the sample cup 200 is located in the loading chamber 1221, the magnetic beads 210 in the sample cup 200 are located in the magnetic field of the permanent magnet to attract the magnetic beads 210. It can be understood that the magnetic induction generated by the magnetic member 122 covers the bearing cavity 1221. That is, before the sample cup 200 enters the supporting chamber 1221, the magnetic member 122 has a small attraction force on the magnetic beads 210 of the sample cup 200 in the sample cup feeding mechanism 110, and is difficult to effectively attract the magnetic beads 210 to restrict the movement thereof, and after the sample cup 200 enters the supporting chamber 1221, the magnetic member 122 attracts the magnetic beads 210 to restrict the movement thereof. Therefore, the sample cup can be prevented from inclining in the process of feeding the sample cup 200 by the sample cup feeding mechanism 110, and the sample cup 200 can be ensured to stably enter the bearing cavity 1221. The magnetic material 122 generates a small attraction force, and attracts only the magnetic beads 210, and does not generate a large attraction force.

Alternatively, the permanent magnet is made of ru fe — b material, and the shape thereof is not limited in principle, as long as it is ensured that the magnetic member 122 can generate a suitable attraction force at the corresponding position, and is prevented from being too large or too small.

Illustratively, the magnetic member 122 includes a permanent magnet made of ru-fe. The permanent magnet is cylindrical and has the size ofThe sample cup 200 had a thickness of 4.75mm, a wall thickness of 0.55mm, a weight of 0.28g, and a diameter of the magnetic bead 210 of 2.3 mm. The center of the circular end face of the magnetic member 122 is aligned with the position where the magnetic beads 210 are naturally placed at the bottom of the sample cup 200, and the thickness of the feeding block 121 between the two is 4.9 mm. Under the above conditions, the design requirements of the present invention can be satisfied, the jumping of the magnetic bead 210 can be ensured to be limited, the sample cup 200 can not be ejected in the moving process, the sample cup 200 can be positioned, and no other fault risk exists.

In another embodiment of the present invention, the magnetic member 122 comprises an electromagnet, and the electromagnet is energized to attract the magnetic beads 210 after the sample cup 200 is located in the supporting cavity 1221. That is, during the process of feeding the sample cup 200 into the loading chamber 1221 of the feeding block 121 by the sample cup feeding mechanism 110, the electromagnet is not energized and does not generate an attractive force to the magnetic beads 210. When the sample cup 200 is located in the loading chamber 1221, the electromagnet is energized to attract the magnetic beads 210, so that the magnetic beads 210 are difficult to move. At this time, the transmission assembly 131 can drive the feeding block 121 to move from the loading position to the unloading position, then the electromagnet is powered off, the magnetic beads 210 lose attraction force, the transfer device 300 transfers the sample cups 200 in the feeding block 121, and after the sample cups 200 are transferred, the transmission assembly 131 drives the sample cups 200 to return to the loading position from the unloading position. It will be appreciated that the electromagnet is de-energized during loading and unloading of the sample cup 200 and return of the feedblock 121 to the loading position. Therefore, the magnetic beads 210 are not popped up in the conveying process of the sample cup 200, the interference of the attraction force of the electromagnet on the loading and unloading process can be avoided, and the loading and unloading of the sample cup 200 are facilitated.

Referring to fig. 1 and 6, in an embodiment, the sample cup conveying device 100 further includes a sample cup storage mechanism 140, the sample cup storage mechanism 140 is disposed corresponding to the sample cup feeding mechanism 110 and is used for storing the sample cups 200, and the sample cup feeding mechanism 110 conveys the sample cups 200 in the sample cup storage mechanism 140 to the feeding block 121. The sample cup storage mechanism 140 is used for storing the sample cup 200 used for sample measurement by the blood coagulation analyzer. It will be appreciated that the sample cup storage mechanism 140 may store a large number of sample cups 200 to enable continuous transport of the sample cups 200 to ensure continuous testing of samples by the coagulation analyzer. When the coagulation analyzer is operated, the sample cup storage mechanism 140 conveys the sample cup 200 to the sample cup feeding mechanism 110, and the sample cup 200 is fed to the bearing cavity 1221 of the feed block 121 by the sample cup feeding mechanism 110.

Optionally, the sample cup storage mechanism 140 includes a cup plate 141 and a tape stripping assembly 142, the cup plate 141 is used for receiving a sample cup tape composed of sample cups 200 and tapes 220 and conveying the sample cup tape to the sample cup feeding mechanism 110, the tape stripping assembly 142 pulls the sample cup tape and strips the tapes 220 from the sample cups 200 at the sample cup feeding mechanism 110, the sample cup feeding mechanism 110 carries the sample cups 200 stripped from the sample cup tape, and the sample cups 200 not yet stripped are pushed to move on the sample cup feeding mechanism 110 by pulling the sample cup tape, and the sample cups 200 which first reach the loading position in the sample cup queue are pushed into the carrying cavities 1221 of the feeding block 121 at the loading position.

Generally, the sample cup strip includes sample cups 200 and a strip 220, the top of the sample cups 200 is clamped on the strip, a plurality of sample cups 200 are arranged in close proximity, and the sample cup strip is arranged in a roll form. This facilitates storage and transportation of the sample cup 200, and also prevents the magnetic beads 210 in the sample cup 200 from falling. The rolled sample cup tape is mounted to the cup plate 141. The cup tray 141 conveys the sample cup tape to the sample cup feeding mechanism 110 while rotating. One end of the tape 220 is connected to the tape peeling assembly 142, and the tape peeling assembly 142 pulls the tape 220 so that the sample cup 200 is separated from the tape 220 while the sample cup feeding mechanism 110 feeds the sample cup 200, and then the sample cup feeding mechanism 110 can feed the sample cup 200 to the feed block 121.

It is understood that, in this embodiment, the tape stripping assembly 142 includes an opener 1421, a pressing roller 1423 and a winding roller 1422, the opener 1421 extends into the gap between the tape 220 and the sample cup 200 to help the sample cup 200 to be stripped from the sample cup tape when the sample cup tape is pulled, the tape 220 on the sample cup tape is opened, the winding roller 1422 is used to connect with the tape 220 and wind the tape 220, and the pressing roller 1423 presses the sample cup tape on the sample cup feeding mechanism 110, so that the sample cup 200 can be properly pressed on the sample cup feeding mechanism 110.

It will be appreciated that, due to the large diameter of the cup tray 141, there is a certain height difference between the loading and unloading positions. Therefore, the transmission assembly 131 conveys the feeding block 121 obliquely upwards in the embodiment. In this way, the driving assembly 131 can drive the feeding block 121 to load the sample cup 200 at the lower loading position and to convey the sample cup to the upper unloading position.

Of course, in other embodiments of the present invention, the sample storage mechanism 140 may also be a storage chamber, the sample cups 200 are arranged in rows and columns in the storage chamber, the sample cups 200 are transferred to the sample cup feeding mechanism 110 by the cup grasping hand, and then the sample cups 200 are fed to the feeding block 121 by the sample cup feeding mechanism 110.

Alternatively, the sample cup feeding mechanism 110 may be a linear pushing structure for linearly pushing the sample cups 200, and has a conveying groove in which the sample cups 200 are placed in a row, that is, the head of the sample cup feeding mechanism 110 feeds the sample cups 200 to the feeding block 121, and the tail of the sample cup feeding mechanism takes the sample cups 200 from the cup tray 141, and pushes the sample cups 200 when the strip tape stripping assembly 142 pulls the strip tape, so that the sample cups 200 that reach the loading position first in the queue of sample cups are pushed into the bearing cavities 1221 of the feeding block 121. Of course, in other embodiments of the present invention, the sample cup feeding mechanism 110 may be a cup grasping hand, by which the sample cup 200 is grasped into the carrying cavity 1221 of the feeding block 121.

In one embodiment, the sample cup transfer device 100 further comprises a cup blocking mechanism 150. The cup blocking mechanism 150 functions to block the sample cup 200 and to block the outlet of the sample cup feeding mechanism 110 for feeding the sample cup 200. It can be understood that, if the cup blocking mechanism 150 is not provided, after the transmission assembly 131 drives the feeding block 121 to disengage from the loading position, the sample cup 200 at the outlet of the sample cup feeding mechanism 110 may fall out under the thrust, so that the cup blocking mechanism 150 may be added to the head of the sample cup feeding mechanism 110 to prevent the sample cup 200 from falling out.

Specifically, when the feeding block 121 leaves the loading position, the cup blocking mechanism 150 moves to the loading position accordingly, and blocks the outlet of the sample cup feeding mechanism 110 for feeding the sample cup 200, so as to block the sample cup 200 from falling out. When the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking mechanism 150 to leave the loading position. That is, the cup blocking mechanism 150 movably sets a loading position of the outlet of the sample cup feeding mechanism 110, and when the feeding block 121 is out of the loading position, the cup blocking mechanism 150 moves to the loading position to block the outlet of the sample cup 200 supplied by the sample cup feeding mechanism 110; when the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking mechanism 150 to leave the loading position.

It will be appreciated that the cup retention mechanism 150 is located on the side of the feedblock 121 when the feedblock 121 is in the loading position. Therefore, interference between the cup blocking mechanism 150 and the feeding block 121 can be avoided, and stable operation of the feeding block 121 is ensured. The cup blocking mechanism 150 includes a cup blocking block and an elastic member connecting the cup blocking block and the sample cup feeding mechanism 110. When the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking block to be away from the loading position, and the elastic piece deforms. When the feeding block 121 leaves the loading position, the elastic piece restores the state before deformation, the cup blocking block resets under the action of the elastic piece, and the outlet of the sample cup feeding mechanism 110 for feeding the sample cup 200 is blocked. The elastic member is a spring in this embodiment, and the spring is compressed when the feeding block 121 pushes the cup blocking block away from the loading position, and the spring is restored to a non-compressed state when the feeding block 121 leaves the loading position.

The present invention also provides a cup feeding method of the sample cup conveying device 100, which is applied to the sample cup conveying device 100 in any of the above embodiments. The cup feeding method comprises the following steps:

the feeding block 121 moves to the loading position;

the sample cup feeding mechanism 110 conveys the sample cup 200 with the magnetic beads 210 to the bearing cavity 1221 of the feeding block 121;

the magnetic member 122 attracts the magnetic beads 210 of the sample cup 200;

The sample cup conveying mechanism 130 controls the feeding block 121 to move from the loading position to the unloading position;

after the sample cup 200 in the feeding block 121 is unloaded, the sample cup feeding mechanism 130 controls the feeding block 121 to move from the unloading position to the loading position.

When the sample cup conveying device 100 conveys the sample cups 200, the transmission assembly 131 drives the feeding block 121 to move to the loading position, and the sample cup feeding mechanism 110 feeds the sample cups 200 with the magnetic beads 210 to the bearing cavity 1221 of the feeding block 121. At this time, the magnetic member 122 attracts the magnetic beads 210 in the sample cup 200, so that the magnetic beads 210 are not easily moved. Subsequently, the sample cup conveying mechanism 130 drives the feeding block 121 to move from the loading position to the unloading position through the transmission assembly 131, and the sample cup 200 in the feeding block 121 is transferred away through the transfer device 300 of the coagulation analyzer. After the sample cup 200 is unloaded, the sample cup conveying mechanism 130 drives the feeding block 121 to move from the unloading position to the loading position through the transmission assembly 131, so as to convey the next sample cup 200.

In one embodiment, the magnetic member 122 is an electromagnet; the process of attracting the magnetic beads 210 of the sample cup 200 by the magnetic member 122 includes the following steps: after the sample cup feeding mechanism 110 conveys the sample cup 200 to the bearing cavity 1221 of the feeding block 121, power is supplied to the electromagnet, and the electromagnet adsorbs the magnetic beads 210 of the sample cup 200 in the bearing cavity 1221. In this embodiment, the cup feeding method further comprises the steps of: when the sample cup conveying mechanism 130 controls the feeding block 121 to move from the loading position to the unloading position, the electromagnet is controlled to be powered off.

During the process of feeding the sample cup 200 into the loading chamber 1221 of the feeding block 121 by the sample cup feeding mechanism 110, the electromagnet is in a power-off state and does not generate an attractive force. When the sample cup 200 is located in the loading chamber 1221, the electromagnet is energized to attract the magnetic bead 210, so that the magnetic bead 210 is fixed and the sample cup 200 is positioned. At this time, the transmission assembly 131 can drive the feeding block 121 to move from the loading position to the unloading position, then the electromagnet is powered off, the magnetic beads 210 lose attraction force, the transfer device 300 can transfer the sample cups 200 in the feeding block 121, and after the sample cups 200 are transferred, the transmission assembly 131 drives the sample cups 200 to return to the loading position from the unloading position. It will be appreciated that in some embodiments, the electromagnet is de-energized during loading and unloading of the sample cup 200 and return of the feedblock 121 to the loading position. Therefore, the magnetic beads 210 are not popped up in the conveying process of the sample cup 200, the interference of the suction force of the electromagnet to the loading and unloading process can be avoided, and the loading and unloading of the sample cup 200 are facilitated.
