[0035] Further, such as Figure 4As shown, the feeding mechanism 2 includes a first electric cylinder 21, a first push rod 23, and a first push plate 24. The first electric cylinder 21 is fixedly connected to the outer wall of the second shell 11. The outer wall of the second shell 11 is provided with a guide groove 22. The first push rod 23 slides in the guide groove 22. One end of the first push rod 23 is fixedly connected to the output end of the first electric cylinder 21. The other end of the first push rod 23 is fixedly connected to the first push plate 24. The second support plate 10 is provided with a first slide groove 25. The bottom of the test tube rack 84 has a protrusion, which can be stuck in the first slide groove 25.

Six rows of test tube racks 84 can be placed in the first slide groove 25. When the number of test tube racks 84 in the area where the discharging mechanism 3 is located is greater than or equal to six, the device alarms and stops working to remind the staff to deal with it in time. Each row of test tube racks 84 can hold 10 test tubes. Each time a row of test tube racks 84 is pushed inward, the interval between pushing the previous row of test tube racks 84 and the next row of test tube racks 84 is 40 seconds.

One end of the screw rod 42 is fixedly connected to the output shaft of the first motor 41, the second push plate 43 is sleeved on the screw rod 42 and the two are threadedly connected. A limiting groove 45 is provided on the rear inner wall of the second shell 11. The limiting groove 45 can ensure that the second push plate 43 can only make a linear motion in the horizontal direction, so as to prevent the second push plate 43 from rotating with the rotation of the screw rod 42, and the second push plate 43 slides in the limiting groove 45.

[0038] Further, such as Figure 7 As shown, the feed support mechanism 5 includes a base 51, a third support plate 53, a second electric cylinder 52, and a second motor 54.

The second support plate 10 is provided with a notch, and the clamping plate 58 can pass through the notch. The bottom of the test tube rack 84 is provided with an embedding groove, and the clamping plate 58 can be stuck in the embedding groove. When the test tube rack 84 is moving, the clamping plate 58 provides support for the test tube rack 84 to prevent the test tube rack 84 from shaking violently. At the same time, when not in use, the clamping plate 58 is moved downward by the second electric cylinder 52, which will not interfere with other operations, thereby improving work efficiency.

[0039] Further, such as Figure 7 As shown, the discharge support mechanism 6 has the same structure as the feed support mechanism 5 .

[0040] Further, such as Figure 8 and Fig. 9 As shown, the driving mechanism 7 includes a water pump 71, a water inlet pipe 72, and a water outlet pipe 73.

A float is placed in the reagent barrel 14, and an alarm is installed above the operating table 12. When the reagent in the reagent barrel 14 reaches the bottom, the float descends and transmits a signal to the alarm through the control module. The alarm sounds, and after the alarm sounds, the entire device stops working through the control module, and the staff is reminded to replace the reagent barrel 14 in time. The number of reagent barrels 14 and dripping tubes 13 in the figure is three, two of which are normally used, and one is reserved for backup.

[0041] Further, such as Fig.10 and Fig.11As shown, the front surface of the operating table 12 is provided with two pages, one of which is a liquid volume control confirmation page 16, which has numeric keys from zero to nine, as well as set and confirm keys. When the test tube rack 84 is improperly placed or the transmission is stopped, the instrument can be initialized by pressing the set key three times in succession and entering the password; the other page is a reagent type and unit selection confirmation page 17, which has milliliter and microliter confirmation keys and a water or diluent selection confirmation key; both pages are connected to the drive mechanism 7 through the control system, and the sensing area 15 is connected to the transmission mechanism 4 and the drive mechanism 7 through the control system.

[0042] Further, such as Figure 1 and Figure 2 As shown, a first baffle 18 is hinged at the opening of the cabinet 1, and the first baffle 18 can provide protection for the parts inside the cabinet 1.

[0043] Further, such as Figure 1 and Figure 8 As shown, a protective shell 83 is provided at the rear of the cabinet 1, and the cabinet 1, the first shell 9, the second shell 11, and the operating table 12 are all threadedly connected to the protective shell 83, and the water outlet pipe 73 is located inside the protective shell 83. The protective shell 83 can protect the water outlet pipe 73.

[0044] (1) When using, the device is assembled, and the staff first confirms the unit and liquid volume of water and diluent on the reagent type and unit selection confirmation page 17 and the control liquid volume confirmation page 16.

[0045] (2) The staff then pulls the third baffle plate 81 out of the second housing 11, places the test tube rack 84 in the first slide groove 25 corresponding to the feeding mechanism 2, and then inserts the third baffle plate 81 into the second housing 11, starts the second electric cylinder 52, and the output shaft of the second electric cylinder 52 pushes the third support plate 53 to move upward, and the third support plate 53 drives the second motor 54, the gear 55, and the rack 56 to move upward, and the rack 56 drives the clamping plate 58 to move upward, and the clamping plate 58 moves to the vicinity of the embedded groove at the bottom of the test tube rack 84, and starts the second motor 54, and the output shaft of the second motor 54 pushes the third support plate 53 to move upward, and the third support plate 53 drives the second motor 54, the gear 55, and the rack 56 to move upward, and the rack 56 drives the clamping plate 58 to move upward, and the clamping plate 58 moves to the vicinity of the embedded groove at the bottom of the test tube rack 84, and then ... The shaft drives the gear 55 to rotate. While the gear 55 rotates, the two racks 56 move to the side away from each other. The rack 56 drives the clamping plate 58 to move. The clamping plate 58 is clamped into the embedded groove, and the first electric cylinder 21 is started. The output shaft of the first electric cylinder 21 drives the push rod to move. The push rod slides in the guide groove 22. The push rod drives the first push plate 24 to move. The first push plate 24 drives the test tube rack 84 to move. The test tube rack 84 slides in the first slide groove 25. After the test tube rack 84 slides into the second slide groove 44, the first electric cylinder 21 stops moving, and the output shaft of the first electric cylinder 21 is retracted.

[0046] (3) After the test tube rack 84 slides to the second slide groove 44, the first motor 41 is started, and the output shaft of the first motor 41 drives the screw rod 42 to rotate. While the screw rod 42 rotates, the second push plate 43 pushes the test tube rack 84 to slide in the second slide groove 44. When the first test tube on the left of the test tube rack 84 reaches the first sensing area 15 on the right, the test tube rack 84 stops moving. At this time, the first test tube on the left is located directly below the first dropper 13 on the right. At this time, the water pump 71 corresponding to the dropper 13 is started, and the water pump 71 pumps the reagent barrel 14 through the water inlet pipe 72 and the water outlet pipe 73. The internal reagent is drawn into the dropper 13, and the reagent is dripped into the test tube through the dropper 13. After the dripping is completed, the test tube rack 84 continues to move, and then, as in the above steps, the second dropper 13 from the right drips the reagent into the first test tube from the left, and at the same time, the first dropper 13 from the right drips the reagent into the second test tube from the left, and this is repeated until all the test tubes on a row of the test tube racks 84 are dripped, the first motor 41 stops moving, and the second push plate 43 is reset. At this time, the protrusion at the bottom of the test tube rack 84 can correspond to the first slide groove 25 in the discharging mechanism 3.

[0047] (4) After the addition of a row of test tubes is completed, the test tube rack 84 that has been added is pushed by the first push plate 24 of the discharge mechanism 3 into the first chute 25 in the area where the discharge mechanism 3 is located, as in step (2). The staff or an external mechanism then takes out the test tube rack 84 that has been added in the first chute 25, and then repeats step (2) to push in the second row of test tube racks 84, and repeats this process.
