[0106] The present invention will be further described below in conjunction with the accompanying drawings.

[0107] like Figure 1 and 8 As shown, the present invention provides a track sample feeding system of a fully automatic chemiluminescence analyzer, which includes a track conveying mechanism 100 and a sample rack temporary storage mechanism 200, wherein the sample rack temporary storage mechanism 200 is arranged at a first end of the track conveying mechanism 100, and a second end of the track conveying mechanism 100 is connected to a sample detection position ( Fig.15 Corresponding to position A shown in the figure, the track conveying mechanism 100 transports the sample rack 240 in the sample rack temporary storage mechanism 200 to the sample detection position, and transports the sample rack 240 back to the sample rack temporary storage mechanism 200 after the host 900 completes the corresponding operation.

[0108] Specifically, the track conveying mechanism 100 includes a detection track 110 and a retracting track 120. The first end of the detection track 110 is connected to the output end of the sample rack temporary storage mechanism 200, the first end of the retracting track 120 is connected to the input end of the sample rack temporary storage mechanism 200, the second end of the detection track 110 is connected to the second end of the retracting track 120, the second end of the retracting track 120 corresponds to the sample detection position of the host 900, and after the host 900 completes the corresponding operation on the sample rack 240 at the second end of the retracting track 120, the retracting track 120 transports the sample rack 240 back to the sample rack temporary storage mechanism 200.

[0109] In one embodiment, after the host 900 completes the operation of adding samples to the sample rack 240 at the second end of the push-back track 120 , the push-back track 120 transports the sample rack 240 back to the sample rack temporary storage mechanism 200 .

[0110] The sample rack temporary storage mechanism 200 includes a to-be-tested portion 210, an inspected portion 220 and a circulating portion 230 which are arranged in sequence. The output end of the to-be-tested portion 210 is connected to the first end of the detection track 110, the input end of the circulating portion 230 is connected to the first end of the push-back track 120, and the output end of the circulating portion 230 is connected to the input ends of the to-be-tested portion 210 and the inspected portion 220, respectively.

[0111] After the test, the sample may meet the requirements or not, and these two situations need to be sent to different locations. Therefore, in the prior art, the sample test results are waited for at the sample test location, and the sample rack is judged to where to be sent after the test results are obtained. Therefore, there is a lot of waiting time, which makes the test efficiency low. In the present invention, by setting a turnover part 230, the sample rack 240 that has completed the test at the sample test location can be sent back to the turnover part 230 by the push-back track 120 to wait for the test results without waiting for the test results at the sample test location. Therefore, the waiting time can be greatly shortened, thereby improving the test efficiency. In addition, since the output end of the turnover part 230 is respectively connected to the input end of the to-be-tested part 210 and the tested part 220, when the test results of the samples in the sample rack 240 in the turnover part 230 are obtained, it can be judged where to send the sample rack 240.

[0112] Specifically, when the sample test results in the sample rack 240 in the turnover section 230 meet the requirements, the sample rack 240 is sent to the tested section 220; when the sample test results in the sample rack 240 in the turnover section 230 do not meet the requirements, the sample rack 240 is sent to the to-be-tested section 210 to wait for retesting.

[0113] The sample rack 240 on the detection track 110 is transported from the first end to the second end, and is moved to the push-back track 120 at the second end to wait for the host 900 to perform corresponding operations. Figure 2 As shown, a track changing mechanism 300 is provided at the second end of the detection track 110 , and the track changing mechanism 300 transfers the sample rack 240 at the second end of the detection track 110 to the second end of the push-back track 120 .

[0114] Furthermore, the track changing mechanism 300 includes a fork plate 310 slidably disposed above the detection track 110 and the push-back track 120 , and a slot 320 for accommodating the sample rack 240 is disposed on the fork plate 310 .

[0115] The track changing mechanism 300 includes a first transmission part 330 and a first sensing part 370 which are electrically connected. The fork plate 310 is connected to the first transmission part 330 . The first sensing part 370 is used to detect whether the sample rack 240 at the second end of the detection track 110 is completely in place.

[0116] 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 front end of the sample rack 240 touches the first sensing part 370. The first sensing part 370 sends a signal to the first transmission part 330 that the sample rack 240 is in place. Then, the first transmission part 330 starts to move, and will drive the fork plate 310 and the sample rack 240 to move to the second end of the push-back track 120. At this time, the position corresponding to the test tube at the rear end of the sample rack 240 is the sample detection position.

[0117] 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. When the first belt 340 is transmitted, the first slider 350 drives the fork plate 310 to move along the first slide rail 360.

[0118] like Figure 2 As shown, during the operation of the first belt 340 , the first slider 350 clamped thereon moves linearly along the first slide rail 360 , thereby driving the fork plate 310 to translate, and the sample rack 240 can be shifted.

[0119] In one embodiment, the first sensing portion 370 is a position sensor.

[0120] Furthermore, a second sensing part 380 electrically connected to the first transmission part 330 is provided at the end of the first slide rail 360, and the second sensing part 380 is used to detect whether the fork plate 310 is located directly above the detection track 110. Since the fork plate 310 needs to return to the top of the detection track 110 to wait for the next sample rack 240 to be moved after transferring the sample rack 240 to the push-back track 120, the position of the fork plate 310 must be directly above the detection track 110, otherwise the sample rack 240 on the detection track 110 will not be able to enter the slot 320 on the fork plate 310. Therefore, when the fork plate 310 is located directly above the detection track 110, the second sensing part 380 sends an electrical signal to the first transmission part 330 indicating that the fork plate 310 is fully in place, so that the first transmission part 330 starts to move.

[0121] In one embodiment, the second sensing unit 380 is a photoelectric sensor. Figure 3 As shown, a first light blocking sheet 391 is disposed on the side of the first sliding block 350 . When the first light blocking sheet 391 blocks the light beam emitted by the photoelectric sensor, it indicates that the fork plate 310 is located directly above the detection track 110 .

[0122] In addition, 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 the length direction of the detection track 120 .

[0123] 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 amount of space.

[0124] like Figure 3 As shown, a recovery pusher 400 is provided at the second end of the push-back track 120, and the recovery pusher 400 moves the sample rack 240 on the push-back track 120 in a direction opposite to the running direction of the detection track 110. The function of the recovery pusher 400 is to move the sample rack 240 at the sample detection position toward the direction close to the turnover portion 230.

[0125] Since each sample rack 240 is provided with at least two test tubes ( Figure 3 FIG. 2 shows a sample rack 240 having five test tubes, so the position of one of the test tubes on the sample rack 240 corresponds to the sample detection position. When the sample in the test tube is loaded, the entire sample rack 240 needs to be pushed so that the next test tube reaches the sample detection position, and thus each test tube in the sample rack 240 is loaded with the sample in turn.

[0126] Specifically, the recovery pusher 400 moves the sample rack 240 on the push-back track 120 each time by a distance equal to the center distance between two test tubes on the sample rack 240 , thereby ensuring that the next test tube is moved exactly to the sample detection position.

[0127] The recovery push handle 400 includes a second transmission part 410 and a first transverse push plate 420 connected to the second transmission part 410. The first transverse push plate 420 is parallel to the length direction of the retreat track 120. Figure 3 As shown, the moving direction of the first transverse push plate 420 is parallel to the length direction of the push-back track 120 , so the first transverse push plate 420 pushes the sample rack 240 to move toward the direction close to the circulation portion 230 .

[0128] 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 transverse push plate 420 is connected to the top of the second slider 440. When the second belt 430 is transmitted, the second slider 440 drives the first transverse push plate 420 to move along the second slide rail 450.

[0129] Furthermore, a third sensing part 460 is provided at both ends of the second slide rail 450, and the third sensing part 460 is used to detect whether the first transverse push plate 420 has reached the limit position. When the first transverse push plate 420 reaches the limit position on the left or the limit position on the right, the third sensing part 460 sends a signal to the second transmission part 410, so that the second transmission part 410 runs in the opposite direction.

[0130] like Figure 3 As shown, during the operation of the second belt 430 , the second slider 440 clamped thereon moves linearly along the second slide rail 450 , thereby driving the first transverse push plate 420 to translate, and the sample rack 240 can be shifted.

[0131] In one embodiment, the third sensing unit 460 is a photoelectric sensor. Figure 4 As shown, a second light blocking sheet 480 is disposed on the side of the second sliding block 440 . When the second light blocking sheet 480 blocks the light beam emitted by the photoelectric sensor, it indicates that the first transverse push plate 420 reaches the limit position.

[0132] 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 track 120 .

[0133] Furthermore, the width of the first transverse pushing 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 evenly apply the force.

[0134] In one embodiment, the first transverse push plate 420 is an L-shaped plate structure.

[0135] In one embodiment, it is determined whether there is a test tube on the sample rack 240 and whether the reagent in the test tube needs to be loaded. If there is a test tube and the reagent in the test tube needs to be loaded, the loading arm module draws the sample therein for loading, thereby quickly and accurately loading the target test tube.

[0136] like Figure 5 As shown, a sample introduction handle 500 is provided at the input end of the inspection part 210, and the sample introduction handle 500 is used to push the sample rack 240 in the inspection part 210 from the input end to the output end. An opening matching the output end of the inspection part 210 is provided on the side wall of the inspection track 110, so that the sample rack 240 can enter the inspection track 110.

[0137] like Figure 4 and 14As shown, the width of the detection track 110 is consistent with the width of the sample rack 240, or slightly larger than the width of the sample rack 240, so that the movement direction of the sample rack 240 in the to-be-tested portion 210 is longitudinal, and the movement direction of the sample rack 240 in the detection track 110 is transverse. Therefore, when the sample rack 240 is transferred from the to-be-tested portion 210 to the detection track 110, there is no need to rotate the direction, and its docking is more convenient, which can save transportation time.

[0138] Similarly, the sample racks 240 in the inspected portion 120 and the circulating portion 130 also move in the longitudinal direction.

[0139] Similarly, the width of the push-back track 120 is consistent with the width of the sample rack 240, or slightly larger than the width of the sample rack 240. Since the sample rack 240 moves from the detection track 110 to the push-back track 120 in a direction perpendicular to the running direction of the detection track 110, the moving direction of the sample rack 240 in the push-back track 120 is also horizontal, thereby reducing the space occupied by the track.

[0140] The test portion 210 can accommodate at least two sample racks 240. Figure 4 The illustrated example is a test portion 210 capable of accommodating 28 sample racks 240 .

[0141] The sample injection pusher 500 includes a third transmission part 510 and a longitudinal push plate 520 . The moving direction of the longitudinal push plate 520 is perpendicular to the moving direction of the first transverse push plate 420 .

[0142] In one embodiment, the third transmission part 510 includes a third belt 530, a third slider 540 clamped on the third belt 530, and a third slide rail 550. The longitudinal push plate 520 is connected to the top of the third slider 540. When the third belt 530 is transmitted, the third slider 540 drives the longitudinal push plate 520 to move along the third slide rail 550.

[0143] The third slide rail 550 is provided with a fourth sensing part 560 at both ends thereof, and the fourth sensing part 560 is used to detect whether the longitudinal push plate 520 has reached the limit position. When the longitudinal push plate 520 reaches the limit position on the left or the limit position on the right, the fourth sensing part 560 sends a signal to the third transmission part 510, so that the third transmission part 510 runs in the opposite direction.

[0144] like Figure 6 As shown, during the operation of the third belt 530 , the third slider 540 clamped thereon moves linearly along the third slide rail 550 , thereby driving the longitudinal push plate 520 to move horizontally, so that the sample rack 240 can be shifted.

[0145] In one embodiment, the fourth sensing unit 560 is a photoelectric sensor. Figure 7As shown, a third light blocking sheet 590 is disposed on the side of the third sliding block 540. When the third light blocking sheet 590 blocks the light beam emitted by the photoelectric sensor, it indicates that the longitudinal push plate 520 has reached the limit position.

[0146] In addition, the third transmission part 510 includes a third motor 580 for driving the third belt 530 , and an output shaft of the third motor 580 is parallel to the width direction of the detection track 120 .

[0147] Furthermore, the length of the longitudinal push plate 520 is at least 1 / 3 of the length of the sample rack 240 , so as to push the sample rack 240 evenly.

[0148] In one embodiment, the longitudinal push plate 520 is in the shape of a long strip. Figure 7 and 8 As shown, a push mechanism 570 is provided at the top of the third slider 540, and the push mechanism 570 is rotatably connected to the longitudinal push plate 520. Specifically, the push mechanism 570 includes a fixed seat 573 fixedly connected to the third slider 540, a lead screw 571 provided in the fixed seat 573, one end of the lead screw 571 is connected to the rotating head 572, and the other end is provided with an ejector pin 574. When one end of the lead screw 571 contacts the ejector pin 574, since the third slider 540 is still sliding, the lead screw 571 starts to rotate under the action of the ejector pin 574, so that the rotating head 572 drives the longitudinal push plate 520 to rotate upward (in the height direction of the sample rack 240), and the longitudinal push plate 520 will not hinder the input end of the to-be-tested part 210, so that the sample rack 240 from the circulating part 230 can enter from the input end of the to-be-tested part 210.

[0149] And, if Figure 6 As shown, a spring 575 is further provided at the connection between the rotating head 572 and the longitudinal push plate 520 . When the longitudinal push plate 520 cannot be rotated by the ejector pin 574 , the longitudinal push plate 520 can be rotated by the spring 575 .

[0150] like Fig. 9 As shown, a push-back handle 600 is provided at the front end of the sample rack temporary storage mechanism 200 , and the push-back handle 600 is used to push the sample rack 240 at the output end of the turnover area to the input end of the to-be-tested part 210 or the input end of the tested part 220 .

[0151] In one embodiment, the push-back handle 600 includes a fourth transmission part 610 and a second transverse push plate 620, and the moving direction of the second transverse push plate 620 is parallel to the moving direction of the second transverse push plate 620. The fourth transmission part 610 includes a fourth belt 630, a fourth slider 640 clamped on the fourth belt 630, and a fourth slide rail 650, and the second transverse push plate 620 is arranged at the upper end of the fourth slider 640.

[0152] Furthermore, both ends of the fourth transmission part 610 are provided with a fifth sensing part 660, and the fifth sensing part 660 is used to detect whether the second transverse push plate 620 has reached the limit position. When the second transverse push plate 620 reaches the limit position on the left or the limit position on the right, the fifth sensing part 660 sends a signal to the fourth transmission part 610, so that the fourth transmission part 610 runs in the opposite direction.

[0153] In one embodiment, the fifth sensing unit 660 is a photoelectric sensor. Fig.10 As shown, a fourth light blocking sheet 680 is disposed on the side of the fourth sliding block 640. When the fourth light blocking sheet 680 blocks the light beam emitted by the photoelectric sensor, it indicates that the second transverse push plate 620 reaches the limit position.

[0154] In addition, the fourth transmission part 610 includes a fourth motor 670 for driving the fourth belt 630 , and an output shaft of the fourth motor 670 is parallel to the length direction of the detection track 120 .

[0155] Furthermore, the length of the second transverse pushing plate 620 is greater than the width of the sample rack 240 so as to push the sample rack 240 evenly.

[0156] In one embodiment, the second transverse push plate 620 is in the shape of an elongated strip.

[0157] like Fig.11 As shown, a downward push handle 700 is provided at the input end of the inspected part 220, and the downward push handle 700 is used to push the sample rack 240 in the inspected part 220 downward from the input end. The downward push handle 700 includes a fifth transmission part 710 and a downward push plate 720, and the moving direction of the downward push plate 620 is parallel and the same as the moving direction of the longitudinal push plate 520.

[0158] In one embodiment, Fig.12 As shown, the fifth transmission part 710 includes the fifth transmission part 610 , and the fifth transmission part 610 includes a fifth motor 730 , a fifth slider 740 connected to the fifth motor, and a fifth slide rail 750 , and the downward push plate 720 is arranged at the upper end of the fifth slider 740 .

[0159] The fifth motor 730 enables the fifth slider 740 to drive the downward push plate 720 to perform reciprocating motion. Seventh sensing parts 760 are respectively provided at both ends of the fifth slider 740. The seventh sensing parts 760 are used to detect the position of the downward push plate 720. The downward push plate 720 pushes the sample rack 240 at the input end of the inspected part 220 downward. After each sample rack 240 is pushed, the downward push plate 720 returns to the initial position to wait for the next sample rack 240 to be pushed.

[0160] In one embodiment, the seventh sensing part 760 is a photoelectric sensor. A fifth light blocking sheet 770 is disposed on the side of the fifth slider 640. When the fifth light blocking sheet 770 blocks the light beam emitted by the photoelectric sensor, it indicates that the downward push plate 720 reaches the limit position.

[0161] In addition, the output shaft of the fifth motor 730 is parallel to the length direction of the detection rail 120 .

[0162] Furthermore, the length of the downward push plate 720 is at least greater than 1 / 3 of the length of the sample rack 240 , so as to evenly push the sample rack 240 .

[0163] In one embodiment, the downward push plate 720 is in the shape of a flat plate.

[0164] The downward push plate 720 is flush with the end surface of the input end of the inspected portion 220 , so the downward push plate 720 will not cause any obstruction to the input end of the inspected portion 220 .

[0165] like Fig.11 As shown, an upward push handle 800 is provided at the input end of the circulation part 230, and the upward push handle 800 is used to push the sample rack 240 in the circulation part 230 from the input end to the output end. The upward push handle 800 includes a sixth transmission part 810 and an upward push plate 820, and the moving direction of the upward push plate 820 is parallel to and opposite to the moving direction of the longitudinal push plate 520.

[0166] The sixth transmission part 810 includes a sixth belt 830 , a sixth slider 840 clamped on the sixth belt 830 , and a sixth slide rail 850 , and the upward push plate is arranged at the upper end of the sixth slider 840 .

[0167] Furthermore, the eighth sensing part 860 is provided at both ends of the sixth transmission part 810, and the eighth sensing part 860 is used to detect whether the upward push plate reaches the limit position. When the upward push plate reaches the limit position on the left or the limit position on the right, the eighth sensing part 860 sends a signal to the sixth transmission part 810, so that the sixth transmission part 810 runs in the opposite direction.

[0168] In one embodiment, the eighth sensing unit 860 is a photoelectric sensor. Fig.13 As shown, a sixth light blocking sheet 880 is disposed on the side of the sixth sliding block 840. When the sixth light blocking sheet 880 blocks the light beam emitted by the photoelectric sensor, it indicates that the upward push plate 820 reaches the limit position.

[0169] In addition, the sixth transmission part 810 includes a sixth motor 870 for driving the sixth belt 830 , and an output shaft of the sixth motor 870 is parallel to the length direction of the detection track 120 .

[0170] Furthermore, the width of the upward pushing plate 820 is at least greater than 1 / 3 of the length of the sample rack 240 so as to push the sample rack 240 evenly.

[0171] In one embodiment, the upward push plate 820 is a U-shaped plate, and the width of the upward push plate 820 described herein is the opening width of the U-shaped plate. Figure 4 As shown, the to-be-tested portion 210, the tested portion 220 and the circulating portion 230 are all provided with a running track 260, and the bottom end of the sample rack 240 is provided with a groove 250, which matches with the running track 260. Thus, when the sample rack 240 is pushed to move in the to-be-tested portion 210, the tested portion 220 and the circulating portion 230, its running track can be kept as a straight line.

[0172] In one embodiment, the detection track 110 is a conveyor belt, and the push-back track 120 is a slide groove arranged parallel to the conveyor belt.

[0173] In addition, the present invention also provides an emergency channel. Specifically, the track conveying mechanism 100 includes an emergency track 130, the first end of the emergency track 130 is an input end or an output end, and the second end of the emergency track 130 corresponds to the emergency sample introduction position of the host 900. The emergency track 130 has a higher priority than the detection channel 110, that is, the sample rack 240 on the emergency channel 130 can be detected in priority to the sample rack 240 on the detection channel 110.

[0174] Specifically, the emergency track 130 is a conveyor belt arranged parallel to the detection track 110 .

[0175] A sixth sensing portion 140 is disposed at the second end of the emergency track 130 . The sixth sensing portion 140 is used to detect whether the sample rack 240 on the emergency track 130 is completely in place.

[0176] When an emergency sample needs to be tested, the sample rack 240 is placed through the first end of the emergency channel 130, and the sample rack 240 is transported to the second end of the emergency channel 130. The second end of the emergency channel 130 corresponds to the emergency sample detection position of the host 900. At this time, the detection channel 110 stops. When the sixth sensing unit 14 detects that the sample rack 240 on the emergency track 130 is completely in place, it sends a signal to the host 900 to make the host 900 add samples from the emergency sample detection position. After the addition of samples is completed, the emergency track 130 runs in the reverse direction, so that the sample rack 240 is transported from the second end to the first end and taken out from the first end.

[0177] Likewise, the width of the emergency track 130 is consistent with the width of the sample rack 240 , or slightly larger than the width of the sample rack 240 , and the moving direction of the sample rack 240 in the emergency track 130 is also horizontal, thereby reducing the space occupied by the track.

[0178] In addition, a scanning unit 150 is disposed on both the detection track 110 and the emergency track 130. A barcode is disposed on the sample rack 240, and when the sample rack 240 passes through the scanning unit 150, the scanning unit 150 can obtain the properties of the samples in the sample rack 240.

[0179] Among them, the barcode format should at least support: Code 128, Code 39, Codabar, 2 / 5 Interleaved.

[0180] Furthermore, since the specifications of the test tubes are different specifications with an outer diameter of 12-16 mm and a height of 75-100 mm, the scanning unit 150 can also support the identification of the types of the test tubes on the sample rack.

[0181] In one embodiment, the sample temporary storage mechanism 200 is disposed on the rack 160. Figure 1 As shown, the bottom end of the rack 160 is provided with rollers 170 for walking and support legs 180 for supporting the rack 160. When the rack 160 needs to be pushed, the rollers 170 are put down and the support legs 180 are folded up to push the rack 160; when the rack 160 needs to be stopped somewhere, the rollers 170 are folded up and the support legs 180 are put down to fix the rack 160 on the ground.

[0182] In addition, a control box 190 is disposed on the frame 160 , which is electrically connected to each sensing part and each transmission part in the above embodiment.

[0183] It should be noted that the horizontal direction in the present invention is the running direction of the detection track 110, that is, Fig.15 The X-axis direction is shown, and the longitudinal direction is Fig.15 The Y-axis direction is shown.

[0184] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
