Description

Technical Field

[0001] The utility model relates to the field of medical instrument detection, in particular to a track sampler docking device. Background Art

[0002] To improve testing efficiency, most existing medical instruments use a track sampler to deliver the sample to be tested into the instrument for testing. However, since a single device can only perform a limited number of tests, it is often necessary to place several identical or different instruments in series. This allows samples that cannot be tested by the previous instrument to flow into the next instrument or several devices in series for testing of other items.

[0003] However, the different inlet and outlet locations of different instruments make smooth docking impossible. Even when connecting the same type of instruments in series, their respective orbital samplers can still experience manufacturing and assembly errors, preventing smooth docking between inlets and outlets. Existing solutions involve raising the instrument base with pads or lowering the footrests. This also requires constant movement and adjustment of the instrument's front-to-back position to achieve alignment, which is time-consuming and labor-intensive, reducing worker efficiency.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0033] In the prior art, when a sample needs to be tested by different instruments,

[0034] Example 1

[0035] This embodiment 1 provides a track sampler docking device, which is used in the serial and parallel detection of a specific protein analyzer, such as Figure 1 As shown, including:

[0036] The support frame 1, in this embodiment, the support mechanism is a frame frame, which ensures the overall support strength while not affecting the work of each structure.

[0037] The sample rack receiving and delivering module 2 is provided on the supporting frame 1 and is used to receive and deliver the sample rack; wherein the sample rack is a square structure and is used to place multiple test tubes, each test tube containing a liquid to be tested;

[0038] The height adjustment component 3 is installed between the support frame 1 and the sample rack transfer module 2 and is used to drive the sample rack transfer module 2 to move up and down.

[0039] In this embodiment, the height adjustment assembly 3 includes a first stepper motor, a belt, a first driving pulley and a first driven pulley. Specifically, the first stepper motor is arranged on the support frame 1, the first driving pulley is sleeved on the output shaft of the first stepper motor, the first driven pulley is rotatably connected to the support frame 1 and is located above the first driving pulley, and the belt is connected between the first driving pulley and the first driven pulley.

[0040] When the first stepper motor is activated, it drives the first driving wheel to rotate or reverse, thereby moving the belt and driving the sample rack transfer module 2 to move synchronously, ultimately achieving height adjustment. It should be understood that the height adjustment component 3 is not limited to this form and can also be a telescopic rod, hydraulic rod, screw slider, etc. to achieve the lifting function.

[0041] Further optimized, the sample rack transfer module 2 includes a support platform 21, a sample introduction track 22 and a conveyor 23;

[0042] The support platform 21 is connected to the height adjustment assembly 3. Specifically, the support platform 21 is fixedly connected to one side of the belt via a connecting frame, and the movement of the belt drives the support platform 21 up and down. To ensure the smooth raising and lowering of the support platform 21, the support frame 1 is provided with two vertical guide rails 11, distributed on both sides of the support frame 1. The support platform 21 is connected to two sliding blocks 211, each of which is configured to slide with the two vertical guide rails 11. The support platform 21 slides vertically on the support frame 1, realizing the vertical position adjustment of the sample rack.

[0043] The sample feed track 22 is mounted on the support platform 21. Specifically, the sample feed track is composed of two baffles and two plate racks, with the two baffles located on top of the two plate racks. The two baffles are symmetrically arranged to form a conveying space that precisely matches the size of the sample rack to be tested.

[0044] The conveying member 23 is arranged at the sample feeding track 22 and is used to receive the sample rack and enter the sample feeding track 22. Specifically, Figure 1 As shown, the conveying member 23 is located between the two baffles. The sample rack to be tested enters the conveying space through the conveying member 23. The feed track is fixed to a certain position, and then the feed track drives the sample rack to be tested to move together.

[0045] Specifically, the conveyor 23 is connected to a drive motor 6, which provides power for the movement of the flat belt. The conveyor 23 comprises a flat belt, a first roller, a second roller, a second driving pulley, a second driven pulley, and a conveyor belt. Specifically, the first and second rollers are rotatably arranged between two frames. The output shaft of the drive motor 6 is connected to the second driving pulley, which is driven by the conveyor belt. The second driven pulley is fixedly sleeved on the first roller, and the first and second rollers are driven by the flat belt.

[0046] The specific working process of the conveying member 23 is:

[0047] The drive motor 6 is started, which drives the second driving wheel to rotate. Under the drive of the conveyor belt, the second driving wheel drives the second driven wheel to rotate. At the same time, the second driven wheel drives the first roller to rotate. The rotation of the first roller drives the rotation of the second roller and the movement of the flat belt. The movement of the flat belt can receive and transport the sample rack.

[0048] This embodiment selects the form of finally driving the flat belt to move through the conveyor belt transmission, realizes the process of automatic transportation, improves the work efficiency of the operator, and the driving motor 6 can be placed in a suitable position to facilitate the normal operation of the entire structure.

[0049] It is known that the conveying member 23 is not limited to the flat belt conveyor form, and can also be a structure for transportation such as roller conveyor.

[0050] Furthermore, to facilitate the entry of the sample rack, guide members 5 are provided at both ends of the sample introduction track 22. In this embodiment, the guide members 5 are two guide plates, which are arranged in a coordinated manner and tilted outward at a certain angle to form a larger opening. The two guide plates are respectively connected to the two baffles.

[0051] Furthermore, since the devices require wiring connections and are positioned differently from one device to another, in order to ensure the neatness and order of the wires, in this embodiment, multiple sets of wire protection drag chains 8 are provided on the support frame 1. As shown in the figure, this embodiment provides two sets of wire protection drag chains 8, each set of which is provided with multiple threading holes to limit and guide the wires. The wire protection drag chains 8 are flexibly configured to adapt to the movement of the support platform 21.

[0052] Furthermore, the support frame 1 is provided with a protective shell 9, with another protective shell 9 located on top of the protective shell 9. While the protective shell 9 provides some protection for the electronic components and parts, it also enhances the overall aesthetics of the device, as multiple components are placed in different locations. The protective shell 9 also provides portability for operators, increasing the practicality of the device.

[0053] In addition, equipment feet are provided at the bottom of the protective shell 9 to ensure the stability of the entire device support.

[0054] In addition, this embodiment further provides a power supply 12 for power supply, and the power supply 12 switch is provided on the protective shell 9 for easy operation by the operator.

[0055] Example 2

[0056] In this embodiment, in order to further adjust the position of the sample rack entering the injection track 22 so that the sample rack can better adapt to the import position of the next instrument, a sliding drive 4 is connected between the injection track 22 and the support platform 21, and the sliding drive 4 is used to drive the injection track 22 to slide horizontally on the support platform 21.

[0057] Specifically, the sliding drive member 4 includes a second stepper motor 43, a gear chain 42 and a sprocket 41. Specifically, the second stepper motor 43 is arranged on the support platform 21. There are two sprockets 41. Both sprockets 41 are rotatably arranged on the support platform 21. A gear chain 42 is engaged between the two sprockets 41. One of the sprockets 41 is connected to the output shaft of the second stepper motor 43 and the sprocket 41 is located directly below the second stepper motor 43. One side of the gear chain 42 is fixedly connected to the plate frame.

[0058] The specific working process of the sliding drive member 4 is:

[0059] The second stepper motor 43 is started, driving the sprocket 41 connected to the second stepper motor 43 to rotate or reverse. Under the linkage of the toothed chain 42, the other sprocket 41 starts to rotate and the toothed chain 42 starts to move. The movement of the toothed chain 42 drives the plate rack and the sample rack located in the conveying space to move to achieve position adjustment.

[0060] In addition, to ensure that the injection track 22 slides smoothly on the support platform 21, a transverse guide rail is provided on the support platform 21. There are two transverse guide rails. Two positioning sliders are provided at the bottom of the injection track 22, which slide with the two transverse guide rails respectively.

[0061] The sample introduction track 22 slides on the support platform 21 to adjust the position of the sample rack in the horizontal direction.

[0062] Example 3

[0063] After the sample rack to be tested comes out of the outlet of the previous testing machine, it enters the sample feed track 22 under the action of the conveying member 23. In order to locate the position of the sample rack on the sample feed track 22, the sample rack transfer module 2 also includes a positioning and identification module 7 for identifying the position of the sample rack and positioning it in the middle of the sample feed track 22.

[0064] Furthermore, the positioning identification module 7 includes a photoelectric sensor 71 and a control mainboard 72.

[0065] The photoelectric sensors 71 are installed at the inlet and outlet ends of the sample introduction track 22 . It can be seen that this embodiment is not limited to the photoelectric sensors 71 , and may also be infrared sensors and displacement sensors.

[0066] The control mainboard 72 is disposed on the support frame 1 , and is connected to the photoelectric sensor 71 and the drive motor 6 respectively. The control mainboard 72 is used to control the drive motor 6 to position the sample rack in the middle of the sample introduction track 22 .

[0067] Specifically, when a sample rack enters the sample feed track 22, the photoelectric sensor 71 at the entrance of the sample feed track 22 senses the sample rack's entry. The photoelectric sensor 71 then feeds the sensed signal back to the control board 72, which then controls the motor to transport the sample rack via the flat belt to the middle of the sample feed track 22, where it stops. This facilitates subsequent horizontal and vertical movement, ultimately aligning the sample rack with the entrance of the next instrument. When the photoelectric sensor at the exit of the sample feed track 22 senses the entrance of the next instrument, the photoelectric sensor 71 feeds the sensed signal back to the control board 72, which then controls the motor to transport the sample rack via the flat belt to the next instrument, thereby exiting the sample feed track 22.

[0068] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
