Technical Field

[0001] This utility model relates to the technical field of testing equipment, specifically to a sample injection device and a specimen testing device. Background Technology

[0002] In test tube sample delivery devices, rapid and accurate sample transport is crucial for achieving efficient testing. Existing stand-alone testing equipment typically employs a single sample transport mode, where sample tubes are placed one by one at the testing point by manual labor or a robotic arm, followed by retrieval. Current technical solutions often use a timing belt to abut both ends of the carrier along its length, positioning the carrier and driving its movement via the timing belt.

[0003] However, while this clamping and fixing method simplifies the structure, in actual operation, the clamping and fixing method may cause interference during the installation and disassembly of the carrier, and this clamping and fixing structure has poor transportation stability, which affects the efficiency of carrier movement.

[0004] As can be seen from the above, the sample injection device in the existing technology has the problems of poor installation stability of the carrier and inconvenience of disassembly and assembly. Utility Model Content

The carrier is slidably disposed on the top surface of the frame and has a mounting groove for placing test tubes. The bottom surface of the carrier has a slot adapted to the shape of the protrusions, and at least a portion of the protrusions is disposed inside the slot for driving the carrier to move.

[0007] Furthermore, multiple bumps are set at equal intervals.

[0008] Furthermore, the bottom surface of the carrier has multiple slots, which are alternatively disposed on the same protrusion; and / or the bottom surface of the carrier has multiple slots, with at least two adjacent protrusions disposed in the multiple slots of the same carrier.

[0010] Furthermore, the frame also includes a support plate, which is connected to the mounting plate and at least partly disposed on the bottom side of the mounting plate. The drive assembly includes a drive component and rollers. The drive component is disposed on the support plate and located on the bottom side of the mounting plate. The rollers are rotatably disposed on the support plate. There are two rollers, which are respectively disposed at both ends of the mounting plate in the length direction. The conveyor belt is sleeved on the two rollers. The drive component is driven and connected to at least one of the rollers through a transmission component.

[0011] Furthermore, the sample injection device also includes a sensor for detecting the position of the bump. The sensor is mounted on the support plate and located on one side of the bottom of the mounting plate. The drive unit and the sensor are spaced apart along the length of the mounting plate.

[0012] Furthermore, the frame also includes a pressure roller assembly, which is disposed on the support plate and located on one side of the bottom of the mounting plate. Along the length of the mounting plate, the pressure roller assembly is disposed between the drive unit and the sensor, and at least a portion of the pressure roller assembly abuts against the surface of the conveyor belt facing the mounting plate.

[0013] Furthermore, the pressure roller assembly includes a mounting frame, a pressure roller component, and a locking component. The support plate has a strip-shaped hole extending along the height direction. The mounting frame is slidably disposed in the strip-shaped hole. The pressure roller component is rotatably disposed on the mounting frame. The outer circumferential surface of the pressure roller component has a plurality of circumferentially spaced ribs that abut against the conveyor belt. The mounting frame is detachably disposed on the support plate by means of the locking component.

[0014] Furthermore, the sample injection device also includes a limiting structure, which is set on the mounting plate of the frame. The limiting structure includes two limiting plates spaced apart along the width direction of the mounting plate, forming a limiting channel between the two limiting plates.

[0031] To address the issues of poor carrier installation stability and inconvenient disassembly / reassembly in existing sample injection devices, this embodiment provides a sample injection device for moving test tubes.

[0032] like Figures 1 to 7 As shown, the sample injection device includes a frame 10, a conveyor belt 20, a drive assembly 30, and a carrier 40. The conveyor belt 20 is disposed on the frame 10 and has a plurality of protrusions 210 spaced apart. The drive assembly 30 is disposed on the frame 10 and is drivenly connected to the conveyor belt 20. The carrier 40 is slidably disposed on the top surface of the frame 10 and has a mounting groove 410 for placing test tubes. The bottom surface of the carrier 40 has a slot 420 adapted to the shape of the protrusions 210. At least a portion of the protrusions 210 is disposed inside the slot 420 for driving the carrier 40 to move.

[0033] The frame 10 includes a base plate, a support plate 120, and a mounting plate 110. Along the height direction of the frame 10, the mounting plate 110 is set on the base plate through the support plate 120. The support plate 120 and the mounting plate 110 can be integrally formed, or they can be detachably connected by fasteners, which can be structural components such as bolts.

[0034] The length direction of frame 10 is Figure 1 The X direction is shown; the width direction of the frame 10 is... Figure 1 The Y direction is shown; the height direction of the frame 10 is... Figure 1 The Z direction is shown.

[0035] The sample injection device of this application employs a slot 420 on the bottom surface of the carrier 40. The slot 420 on the bottom surface of the carrier 40 can engage with the protrusion 210 on the conveyor belt 20, thereby positioning the carrier 40 on the conveyor belt 20 and allowing it to move under the drive of the conveyor belt 20. The slot 420, located on the bottom surface of the carrier 40, ensures that the mounting point of the carrier 40 is at its bottom, facilitating the assembly and disassembly of the carrier 40 from the conveyor belt 20. The structure of the slot 420 and the protrusion 210 allows the carrier 40 to be fixed at different protrusion 210 positions, thus achieving flexibility in the installation of the carrier 40. Furthermore, the engagement of the protrusion 210 and the slot 420 further ensures precise positioning of the carrier 40, guaranteeing that the carrier 40 can move accurately to the target position, improving the stability of the carrier 40 during transportation and the flexibility of its installation, thereby increasing the efficiency of the sample injection device.

[0036] In this embodiment, the bottom surface of the carrier 40 has multiple slots 420, which are interchangeably disposed on the same protrusion 210. The multiple protrusions 210 of this application provide multiple mounting points. All slots 420 of the carrier 40 can be fitted to the same protrusion 210. When the carrier 40 is installed at different positions relative to the conveyor belt 20, different slots 420 are installed on the protrusion 210, thereby achieving adjustable mounting of the carrier 40 on the conveyor belt 20. The structural design of this application allows for adjustment of the mounting position of the carrier 40, improving the flexibility of the carrier 40's mounting position.

[0037] In this embodiment, the bottom surface of the carrier 40 has multiple slots 420, and at least two adjacent protrusions 210 are disposed in the multiple slots 420 of the same carrier 40. The mounting structure of multiple protrusions 210 can be adapted to one carrier 40, which is beneficial to improving the stability of the carrier 40 installation, realizing the precise positioning and stable transmission of the carrier 40 during the conveying process, and preventing positional deviation due to external interference during the transmission process.

[0038] like Figures 1 to 4 As shown, the conveyor belt 20 has a ring structure, and the mounting plate 110 is formed inside the area of ​​the ring structure so that a part of the conveyor belt 20 is disposed on one side of the top surface of the mounting plate 110 and another part is disposed on one side of the bottom surface of the mounting plate 110. The part of the conveyor belt 20 located on the top surface of the mounting plate 110 can drive the carrier 40 to move through the protrusion 210.

[0039] Specifically, the conveyor belt 20 of this application has multiple protrusions 210 evenly spaced, which can be used to provide multiple engagement positions for placing the carrier 40, thereby achieving stable and uniform pushing of the carrier 40. The multiple protrusions 210 evenly spaced can be used to install carriers 40 of different sizes; and the protrusions 210 can be used to control the distance, so that when multiple carriers 40 are placed, the distance between two adjacent carriers 40 can be determined by the protrusions 210; at the same time, the arrangement of multiple protrusions 210 can avoid the problem of collision between carriers 40, improving the stability and safety of the structure.

[0040] The protrusion 210 is positioned facing away from the mounting plate 110, and thus the protrusion 210 can be adapted to the slot 420 on the carrier 40 to enable the carrier 40 to be snapped onto the conveyor belt 20.

[0041] In this embodiment, the carrier 40 is slidably disposed on the top surface of the mounting plate 110. Along the height direction of the frame 10, a portion of the conveyor belt 20 disposed on one side of the top surface of the mounting plate 110 is disposed on the bottom of the carrier 40. The protrusion 210 on this portion engages with the slot 420 on the bottom surface of the carrier 40 for positioning and installation. The mounting plate 110 supports the carrier 40, and the conveyor belt 20 provides driving force for the movement of the carrier 40. The carrier 40 of this application can slide stably along the top surface of the mounting plate 110 under the drive of the synchronous belt. The protrusion 210 ensures precise positioning and a secure connection between the carrier 40 and the synchronous belt, so that the synchronous belt can accurately push the carrier 40 to adjust its position when moving in both directions.

[0042] like Figure 5 and Figure 6 As shown, the drive assembly 30 includes a drive member 310 and a roller 320. The drive member 310 is disposed on the support plate 120 and located on one side of the bottom of the mounting plate 110. The roller 320 is rotatably disposed on the support plate 120. There are two rollers 320, which are respectively disposed at both ends of the mounting plate 110 in the length direction. The conveyor belt 20 is sleeved on the two rollers 320. The drive member 310 is driven and connected to at least one of the rollers 320 through the transmission member 330.

[0043] In this design, the driving component 310 is a motor, and the transmission component 330 can be either a transmission belt or a chain. When the transmission component 330 is a transmission belt, pulleys are respectively provided on the output shaft of the driving component 310 and the roller 320, thereby enabling the driving component 310 to drive the roller 320 to rotate through the cooperation of the pulleys and the transmission belt. When the transmission component 330 is a chain, sprockets are respectively provided on the output shaft of the driving component 310 and the roller 320, thereby enabling the driving component 310 to drive the roller 320 to rotate through the cooperation of the sprockets and the chain.

[0044] In this embodiment, the driving component 310 can be one to drive one of the rollers 320, or two can be provided, with the two driving components 310 respectively used to drive the two rollers 320 to rotate.

[0045] like Figure 3 and Figure 4 As shown, the sample injection device also includes a sensor 50 for detecting the position of the bump 210. The sensor 50 is disposed on the support plate 120 and located on the bottom side of the mounting plate 110. Along the length direction of the mounting plate 110, the drive unit 310 and the sensor 50 are spaced apart.

[0046] The sensor 50 can be an infrared sensor 50, but is not limited to an infrared sensor 50. The sensor 50 can also be other sensors 50 that can be used to detect the bump 210.

[0047] Specifically, in this application, the sensor 50 is disposed on the bottom side of the mounting plate 110 and connected to the support plate 120. The support plate 120 provides an installation position for the sensor 50. The sensor 50 is disposed on the bottom side of the mounting plate 110 to make reasonable use of the installation space and avoid the sensor 50 occupying the space on the top side of the mounting plate 110, which would cause interference with the bracket 40.

[0048] In this embodiment, the carrier 40 is disposed on the top surface of the mounting plate 110. Therefore, the sensor 50 is disposed on the bottom side of the mounting plate 110, which facilitates the position detection of the protrusions 210 of the conveyor belt 20 and improves the detection accuracy. Furthermore, this application employs a layout where the sensor 50 and the drive unit 310 are spaced apart along the length of the carrier 10, further ensuring the detection accuracy of the sensor 50. The sensor 50 can transmit the position information of the protrusions 210 to the terminal, enabling real-time detection of the protrusion position 210.

[0049] like Figure 5 As shown, the frame 10 also includes a pressure roller assembly 60, which is disposed on the support plate 120 and located on one side of the bottom of the mounting plate 110. Along the length direction of the mounting plate 110, the pressure roller assembly 60 is disposed between the drive member 310 and the sensor 50, and at least a portion of the pressure roller assembly 60 abuts against the surface of the conveyor belt 20 facing the mounting plate 110.

[0050] The pressure roller assembly 60 is designed to ensure that the conveyor belt 20 maintains stable rotation, thus preventing the conveyor belt 20 from becoming loose and affecting the movement of the carrier 40.

[0051] Specifically, this application arranges the pressure roller assembly 60 on the support plate 120 and on one side of the bottom of the mounting plate 110 to avoid interference with the carrier 40 that would affect the movement of the carrier 40. The structural arrangement of the pressure roller assembly 60, sensor 50 and drive component 310 in this application makes reasonable use of the installation space and ensures the stable operation of the carrier 40.

[0052] In this embodiment, the pressure roller assembly 60 is movable along the height direction of the frame 10, thereby adapting to conveyor belts 20 of different sizes, so that conveyor belts 20 of different sizes can be in a taut state, thereby ensuring the stability of the carrier 40 during transportation.

[0053] Specifically, the pressure roller assembly 60 includes a mounting frame 610, a pressure roller component 620, and a locking component. A portion of the mounting frame 610 is slidably disposed in the strip-shaped hole, and the pressure roller component 620 is rotatably disposed on the mounting frame 610. The outer circumferential surface of the pressure roller component 620 has a plurality of circumferentially spaced protrusions 630, which abut against the conveyor belt 20. The mounting frame 610 is disposed on the support plate 120 by the locking component.

[0054] The mounting bracket 610 has a shaft structure that extends into the slotted hole. The shaft structure can move up and down along the slotted hole, thereby changing the overall position of the mounting bracket 610. When it moves to the preset position, the mounting bracket 610 can be fixedly connected to the support plate 120 by a locking element. The locking element can be a bolt.

[0055] The pressure roller 620 of this application adopts a structure with multiple ribs 630, which is beneficial to assisting the movement of the conveyor belt 20, further ensuring the effect of pressing against the conveyor belt 20, and ensuring the stability of the conveyor belt 20 during transportation.

[0056] like Figure 3 and Figure 5 As shown, the sample injection device also includes a limiting structure 70, which is disposed on the mounting plate 110 of the frame 10. The limiting structure 70 includes two limiting plates 710 spaced apart along the width direction of the mounting plate 110, forming a limiting channel 720 between the two limiting plates 710. The conveyor belt 20 passes through the limiting channel 720, and the limiting structure 70 is used to limit the conveyor belt 20.

[0057] The main function of the limiting structure 70 is to precisely guide and position the conveyor belt 20, ensuring the stability of its running trajectory and preventing possible deviation or vibration during high-speed or frequent turning. By limiting the range of movement of the conveyor belt 20, this structure not only enhances the overall mechanical strength and reliability of the device, but also significantly optimizes the transport efficiency of the sample carrier 40, ensuring the continuity and accuracy of the testing process.

[0058] In the embodiments of this application, the operation of the sample introduction device is as follows: First, the slot 420 at the bottom of the test tube carrier 40 is aligned and engaged with at least one of the protrusions 210 on the conveyor belt 20. The drive component 310 in the drive assembly 30 is activated, driving the roller 320 to rotate through the transmission component 330, thereby causing the conveyor belt 20 to move. The protrusions 210 on the synchronous belt are evenly distributed. When the protrusions 210 enter the slot 420 at the bottom of the carrier 40, the carrier 40 can be driven to move along the top surface of the mounting plate 110. During the forward and reverse movement of the synchronous belt, the protrusions 210 always maintain contact with the slot 420 of the carrier 40, ensuring that the carrier 40 moves synchronously back and forth. At the same time, the sensor 50 monitors the position information of the protrusions 210 in real time, providing necessary data to the control system to calculate the optimal position for the synchronous belt to stop and wait for the next action, ensuring accurate docking of the carrier 40 in multi-station detection. The pressure roller 620 of the pressure roller assembly 60 presses against the side surface of the conveyor belt 20 facing the mounting plate 110, improving the accuracy and stability of the carrier 40's movement. The limiting plates 710 in the limiting structure 70 are spaced apart along the width of the mounting plate 110, forming a limiting channel 720. This ensures that the conveyor belt 20 runs within the limiting channel 720, preventing lateral deviation during high-speed movement or turning, and guaranteeing the stability of the carrier 40 during transport.

[0059] This embodiment also provides a specimen testing device, which includes the above-described sample injection device.

[0060] The specimen testing equipment integrates the aforementioned sample introduction device and adopts a structure of slot 420 and protrusion 210, which can fix the carrier 40 on the conveyor belt 20, ensuring that the carrier 40 can move accurately to the target position, improving the stability of the carrier 40 transportation and the flexibility of installation, thereby improving the efficiency of the testing equipment.

[0061] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0062] The sample injection device of this application employs a slot 420 on the bottom surface of the carrier 40. The slot 420 on the bottom surface of the carrier 40 can engage with the protrusion 210 on the conveyor belt 20, thereby positioning the carrier 40 on the conveyor belt 20 and allowing it to move under the drive of the conveyor belt 20. The slot 420, located on the bottom surface of the carrier 40, ensures that the mounting point of the carrier 40 is at its bottom, facilitating the assembly and disassembly of the carrier 40 from the conveyor belt 20. The structure of the slot 420 and the protrusion 210 allows the carrier 40 to be fixed at different protrusion 210 positions, thus achieving flexibility in the installation of the carrier 40. Furthermore, the engagement of the protrusion 210 and the slot 420 further ensures precise positioning of the carrier 40, guaranteeing that the carrier 40 can move accurately to the target position, improving the stability of the carrier 40 during transportation and the flexibility of its installation, thereby increasing the efficiency of the sample injection device.
