Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 15, the utility model provides a full-automatic chemiluminescence analyzer's track sampling system, it includes track conveying mechanism 100 and sample frame temporary storage mechanism 200, sample frame temporary storage mechanism 200 sets up the first end at track conveying mechanism 100, the second end of track conveying mechanism 100 is corresponding with the sample detection position (the A department shown in fig. 15) of host computer 900, track conveying mechanism 100 transports sample frame 240 in with sample frame temporary storage mechanism 200 to the sample detection position, treat to transport sample frame 240 back sample frame temporary storage mechanism 200 after host computer 900 accomplishes corresponding operation.

Specifically, the rail conveying mechanism 100 includes the detection rail 110 and the retreat push rail 120, the first end of the detection rail 110 is connected with the output end of the sample holder temporary storage mechanism 200, the first end of the retreat push rail 120 is connected with the input end of the sample holder temporary storage mechanism 200, the second end of the detection rail 110 is connected with the second end of the retreat push rail 120, the second end of the retreat push rail 120 corresponds to the sample detection position of the host computer 900, the host computer 900 completes the corresponding operation to the sample holder 240 of the retreat push rail 120 second end, and the retreat push rail 120 transports the sample holder 240 back to the sample holder temporary storage mechanism 200.

In one embodiment, after the host 900 completes the sample adding operation on the sample rack 240 at the second end of the pushing track 120, the pushing track 120 transports the sample rack 240 back to the sample rack buffer mechanism 200.

The temporary storage mechanism 200 comprises a to-be-detected part 210, a detected part 220 and a turnover part 230 which are sequentially arranged, wherein the output end of the to-be-detected part 210 is connected with the first end of the detection track 110, the input end of the turnover part 230 is connected with the first end of the backward pushing track 120, and the output end of the turnover part 230 is respectively connected with the input ends of the to-be-detected part 210 and the detected part 220.

After detection, the sample has two conditions of meeting requirements and not meeting requirements, and the two conditions need to be sent to different parts, so in the prior art, the detection result of the sample is waited at a sample detection position, the judgment is carried out after the detection result is obtained, and the position to which the sample frame is sent is determined, so a large amount of waiting time exists, and the detection efficiency is low. In the present invention, by providing the transferring part 230, the sample rack 240 that has completed the detection at the sample detection position can be returned to the transferring part 230 by the back pushing rail 120 to wait for the detection result without waiting for the detection result at the sample detection position, so that the waiting time can be greatly shortened, thereby improving the detection efficiency; in addition, since the output end of the transferring unit 230 is connected to the input ends of the inspecting unit 210 and the inspected unit 220, respectively, when the result of the inspection of the sample in the sample rack 240 in the transferring unit 230 is obtained, it can be determined where the sample rack 240 is to be loaded.

Specifically, when the sample detection result in the sample rack 240 in the transferring part 230 meets the requirement, the sample rack 240 is sent to the detected part 220; when the result of the sample detection in the sample rack 240 in the transferring section 230 is not satisfactory, the sample rack 240 is sent to the waiting section 210 to be detected again.

The sample rack 240 on the detection track 110 is transported from the first end to the second end, and is moved to the retreat track 120 at the second end to wait for the host 900 to perform corresponding operations. Specifically, as shown in fig. 2, the second end of the detection track 110 is provided with a track transfer mechanism 300, and the track transfer mechanism 300 transfers the sample rack 240 at the second end of the detection track 110 to the second end of the pushing track 120.

Further, the track transfer mechanism 300 includes a fork plate 310 slidably disposed above the detection rail 110 and the retreat rail 120, and a groove 320 for accommodating the sample rack 240 is disposed on the fork plate 310.

The track transfer mechanism 300 includes a first transmission part 330 and a first sensing part 370 electrically connected to each other, the fork plate 310 is connected to the first transmission part 330, and the first sensing part 370 is used for detecting whether the sample rack 240 at the second end of the detection track 110 is fully seated.

When the sample rack 240 on the detection track 110 moves to the second end of the detection track 110, the sample rack 240 enters the slot 320 on the fork plate 310, when the sample rack 240 completely enters the slot 320, the foremost end of the sample rack 240 touches the first sensing portion 370, the first sensing portion 370 sends a signal that the sample rack 240 is in place to the first transmission portion 330, the first transmission portion 330 starts to move, the fork plate 310 and the sample rack 240 are driven to move together to the second end of the backward pushing track 120, and the position corresponding to the test tube at the rearmost end of the sample rack 240 is the sample detection position.

In one embodiment, the first transmission part 330 includes a first belt 340, a first slider 350 clamped on the first belt 340, and a first slide rail 360, the fork plate 310 is connected to the bottom of the first slider 350, and the first slider 350 drives the fork plate 310 to move along the first slide rail 360 when the first belt 340 transmits.

As shown in fig. 2, during the operation of the first belt 340, the first slider 350 clamped thereon moves linearly along the first slide rail 360, so as to drive the fork plate 310 to translate, thereby displacing the sample rack 240.

In one embodiment, the first sensing part 370 is a position sensor.

Further, a second sensing portion 380 electrically connected to the first transmission portion 330 is disposed at an end of the first slide rail 360, and the second sensing portion 380 is used for detecting whether the fork plate 310 is located right above the detection track 110. Since the fork plate 310 needs to return to the upper side of the detection track 110 to be moved for the next sample rack 240 after transferring the sample rack 240 onto the pushing-back track 120, the position of the fork plate 310 must be right above the detection track 110, otherwise the sample rack 240 on the detection track 110 cannot enter the slot 320 on the fork plate 310. Therefore, when the fork plate 310 is positioned right above the sensing rail 110, the second sensing part 380 sends an electric signal that the fork plate 310 is completely seated to the first driving part 330, thereby starting the movement of the first driving part 330.

In one embodiment, the second sensing part 380 is a photosensor. As shown in fig. 3, a first light-blocking sheet 391 is disposed at a side portion of the first slider 350, and when the first light-blocking sheet 391 blocks the light beam emitted by the photosensor, it means that the fork 310 is located right above the detection track 110.

Further, the first transmission part 310 includes a first motor 390 for driving the first belt 340, and an output shaft of the first motor 390 is parallel to a longitudinal direction of the detection rail 120.

In one embodiment, the running direction of the first belt 340 is perpendicular to the running direction of the detection track 110, which can save a certain space.

As shown in fig. 3, the second end of the retreat rail 120 is provided with a recovery pusher 400, and the recovery pusher 400 moves the sample rack 240 on the retreat rail 120 in a direction opposite to the running direction of the detection rail 110. The recovery pusher 400 functions to move the sample rack 240 located at the sample detection position toward the transfer unit 230.

Because each sample rack 240 is provided with at least two test tubes (fig. 3 shows that one sample rack 240 has 5 test tubes), the position where one of the test tubes on the sample rack 240 is located corresponds to the sample detection position, and after the sample loading in the test tube is completed, the whole sample rack 240 needs to be pushed, so that the next test tube reaches the sample detection position, and thus, the loading of each test tube in the sample rack 240 is completed in sequence.

Specifically, the recovery pusher 400 moves the sample rack 240 on the retreat rail 120 by the center distance of two test tubes on the sample rack 240 each time, so as to ensure that the next test tube moves to the sample detection position.

The recycling pushing hands 400 comprise a second transmission part 410 and a first transverse pushing plate 420 connected with the second transmission part 410, wherein the first transverse pushing plate 420 is parallel to the length direction of the pushing back track 120. As shown in fig. 3, the first lateral push plate 420 moves in a direction parallel to the length direction of the backward push rail 120, so that the first lateral push plate 420 pushes the sample rack 240 to move closer to the turnaround part 230.

In one embodiment, the second transmission part 410 includes a second belt 430, a second slider 440 clamped on the second belt 430, and a second slide rail 450, the first lateral pushing plate 420 is connected to the top of the second slider 440, and the second slider 440 drives the first lateral pushing plate 420 to move along the second slide rail 450 when the second belt 430 transmits power.

Further, both ends of the second slide rail 450 are provided with a third sensing portion 460, and the third sensing portion 460 is used for detecting whether the first lateral push plate 420 reaches the limit position. When the first lateral push plate 420 reaches the extreme position on the left side or the extreme position on the right side, the third sensing part 460 sends a signal to the second transmission part 410, so that the second transmission part 410 operates in the opposite direction.

As shown in fig. 3, during the operation of the second belt 430, the second sliding block 440 clamped thereon moves linearly along the second sliding rail 450, so as to drive the first transverse pushing plate 420 to translate, thereby displacing the sample rack 240.

In one embodiment, the third sensing part 460 is a photosensor. As shown in fig. 4, the second slider 440 is provided with a second light blocking plate 480 at a side thereof, and when the second light blocking plate 480 blocks the light beam emitted from the photo sensor, it means that the first lateral push plate 420 reaches the limit position.

In addition, the second transmission part 410 includes a second motor 470 for driving the second belt 430, and an output shaft of the second motor 470 is perpendicular to the length direction of the detection rail 120.

Further, the width of the first lateral push plate 420 is the same as the width of the sample rack 240, or slightly larger than the width of the sample rack 240, so as to uniformly apply the force.

In one embodiment, the first lateral push plate 420 is an L-shaped plate structure.

In one embodiment, it is determined whether there is a test tube on the sample rack 240 and whether to perform a sample adding operation on a reagent in the test tube, and if there is a test tube and the reagent in the test tube needs to perform a sample adding operation, the sample adding arm module absorbs a sample therein to perform a sample adding operation on the target test tube quickly and accurately.

As shown in fig. 5, an input end of the inspection part 210 is provided with a sample pushing hand 500, and the sample pushing hand 500 is used for pushing the sample rack 240 in the inspection part 210 from the input end to the output end. An opening matched with the output end of the to-be-inspected portion 210 is provided on the side wall of the inspection rail 110 so that the sample holder 240 can enter the inspection rail 110.

As shown in fig. 4 and 14, the width of the detection track 110 is the same as the width of the sample rack 240, or slightly larger than the width of the sample rack 240, so that the traveling direction of the sample rack 240 in the waiting portion 210 is a longitudinal direction and the traveling direction of the sample rack 240 in the detection track 110 is a transverse direction, and thus the sample rack 240 does not need to be rotated when being transferred from the waiting portion 210 to the detection track 110, and the docking thereof is more convenient and the transportation time can be saved.

Similarly, the traveling directions of the specimen rack 240 in the examined section 120 and the turnaround section 130 are also both longitudinal.

Similarly, the width of the retreat rail 120 is equal to the width of the sample rack 240, or slightly larger than the width of the sample rack 240, and since the sample rack 240 is transferred in a direction perpendicular to the running direction of the detection rail 110 when transferring from the detection rail 110 to the retreat rail 120, the running direction of the sample rack 240 in the retreat rail 120 is also transverse, thereby reducing the space occupied by the rails.

The waiting portion 210 can accommodate at least 2 sample racks 240, and fig. 4 shows the waiting portion 210 that can accommodate 28 sample racks 240.
