Description

Technical Field

[0001] The invention belongs to the technical field of fluorescent immunoassay detection equipment, and in particular relates to a diluent component used in an analyzer. Background Art

[0002] The diluent detection technology is a commonly used detection technology in biomedical testing. This technology uses the characteristic that the analyzed substance will produce fluorescence under the excitation of light of a specific wavelength to perform qualitative and quantitative detection. Due to its high sensitivity, strong specificity, fast detection speed, safety and stability, the diluent detection technology is widely used in clinical testing and has broad application prospects in the detection of endocrine diseases, infectious diseases, obstetrics and gynecology, tumor markers, genetic diseases, blood and cytology.

[0003] The design of the diluent assembly is particularly important for the diluent detection technology. In the Chinese patent document CN216484253U, a bracket-type liquid-adding dilution device for a laboratory is disclosed, including a base and an outer tube. The outer tube is welded at the center of the upper end of the base. The outer tube is threadedly connected to the sliding sleeve, and the sliding sleeve is welded to the lower bracket. A piston rod is passed through the outer tube. The upper end of the piston rod is connected to a rotating device, and the lower end is connected to a hydraulic pump arranged in the base to realize the lifting and lowering of the piston. The rotating device is fixedly connected to the upper bracket. Four liquid adders are arranged on the upper bracket, and two mixers are arranged at both ends of the lower bracket. Two symmetrically arranged vibration stirring devices are arranged on the base.

[0004] In the above technical solution, although different types of diluents can be put into the liquid adder, and then injected into the mixer to mix and flow into the glass bottle for vibration and stirring, rapid dilution and stirring can be achieved, saving manpower and time, and the operation is convenient and fast with high production efficiency. However, it does not have a foolproof function during specific use, and the operator has the risk of misplacing the diluent bottle, which will cause machine operation failure.

[0005] Therefore, it is necessary to develop a new diluent assembly that can prevent operators from misplacing the diluent bottle due to mistakes during operation. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a diluent component which can prevent operators from misplacing a diluent bottle.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a diluent component, including a power device, a supporting device, a transport device and a diluent bracket, the transport device is arranged on the supporting device, the power device provides power for the transport device, the diluent bracket is arranged on the upper end of the transport device, and is characterized in that a micro switch is arranged in the diluent bracket, the diluent bracket is used to store the diluent bottle, and the diluent bottle can be pushed in by the transport device for sample injection or / and pushed out for sample discharge after touching the micro switch.

[0008] The diluent holder is mainly composed of a holder cover, a holder and a micro switch, wherein the micro switch is welded on the cover, and the cover and the micro switch are assembled on the holder together, and are used to detect whether the diluent bottle is placed in the correct position in the diluent holder. The diluent holder is used to store the diluent bottle. When the diluent bottle is placed correctly, it will touch the micro switch. If the diluent bottle is placed incorrectly, the diluent bottle cannot touch the micro switch on the diluent holder. When the machine is running, there will be a prompt on the main interface, thereby reminding the operator to check whether the diluent bottle is placed incorrectly.

[0009] Preferably, the supporting device comprises a supporting plate and a supporting column, and the supporting column is embedded in the lower end of the supporting plate.

[0010] The support plate is a rectangular plate structure with a flat upper surface to accommodate the installation of the diluent bracket and transport device. The bottom of the support column is equipped with an anti-skid rubber pad to increase friction and ensure the stability and safety of the support device. In addition, there are four hole structures on the support plate. The support column and the hole structure on the support plate are connected by interference fit, which has a high load-bearing capacity, so that the diluent assembly can work more reliably under impact and vibration loads, thereby improving the support capacity.

[0011] Preferably, the transport device includes a synchronous belt, a driving wheel, a driven wheel, a linear guide rail, a slider, a slider mounting plate and a limit device, the slider mounting plate is fixed to the lower end of the slider, the lower end surface of the slider is connected to the linear guide rail and slides left and right along the linear guide rail, and the linear guide rail is fixed on the support plate.

[0012] The fixing screw fixes the linear guide to the support plate, ensuring that the linear guide is firmly connected to the upper surface of the support plate. The design of the slider mounting plate serves as a transition between the slider and the diluent bracket, enhancing the stability of the sliding connection between the transport device and the diluent bracket.

[0013] Preferably, the synchronous belt is fitted on the outer circumference of the driving wheel and the driven wheel, the driving wheel is connected to the power device through an inner rod, the inner rod is located in the power device, the driven wheel is equipped with a driven wheel shaft, and the driven wheel shaft is embedded in the support plate.

[0014] The synchronous belt is arranged around the driving wheel and the driven wheel. The synchronous belt is driven by the driving wheel to move, so as to achieve the precise left and right movement of the slider along the linear guide. The driving wheel is driven by the stepper motor through the inner rod connection. The speed and direction of the stepper motor are adjusted by the control system to meet the needs of different speeds. The driven wheel plays the role of tensioning the synchronous belt to ensure the stability and synchronization of the synchronous belt during movement.

[0015] Preferably, the power device is a stepper motor, and two through holes are provided on the driving wheel. The inner rod cooperates with the two through holes to fix the driving wheel to the upper end of the stepper motor. The stepper motor provides power for the driving wheel, and the driving wheel drives the synchronous belt and the driven wheel to rotate through gear meshing. When the synchronous belt rotates, it drives the slider and the slider mounting plate to slide left and right on the linear guide rail.

[0016] Through its precise control capability, the stepper motor provides a power output in microsteps, so that the rotation of the driving wheel can be precisely controlled, thus ensuring the smooth and precise movement of the synchronous belt. Each step angle of the stepper motor represents a small part of the rotation of the driving wheel, allowing the system to position and adjust the speed with high precision.

[0017] Two through holes are set on the driving wheel, and the driving wheel passes through the inner rod. Two positioning clamps are set on the inner rod. The two positioning clamps are matched with the two through holes on the driving wheel to fix the driving wheel to the upper end of the inner rod. The inner rod plays a key role in transmitting torque. By fixing the driving wheel and the inner rod, the coaxial alignment of the driving wheel and the stepper motor is ensured, thereby avoiding unnecessary vibration or deviation during the movement. This fixing method simplifies the assembly process and improves the reliability and durability of the power device and the transportation device.

[0018] Preferably, the limiting device is located below the slider mounting plate, and the limiting device includes an optical coupler and an optical coupler baffle, the optical coupler baffle is connected to the lower end surface of the slider mounting plate and slides together with the slider mounting plate, and the optical coupler is fixed on the support plate.

[0019] The limit device is designed to provide precise position control and process safety through photoelectric sensing technology. The optical coupler consists of a transmitter and a receiver, where the transmitter continuously emits light signals and the receiver is responsible for receiving these light signals. The optical coupler baffle is designed to be opaque material and is installed on the lower end surface of the slider mounting plate. It slides left and right on the linear guide with the slider mounting plate.

[0020] As the slider mounting plate moves, the optocoupler baffle moves with it. When the baffle enters the light path between the transmitter and the receiver, it blocks the light from the transmitter to the receiver, thereby changing the state of the receiver. This change in state is detected by the electronic control system, which then issues a command to control the stepper motor to stop moving, thereby accurately controlling the position of the slider mounting plate to ensure that it does not exceed the set range of motion. This ensures the safe operation of the device and prevents overshoot and collision during the mechanical process.

[0021] In addition, the optical coupler is fixed on the support plate, and the fixed position ensures the stability of the light path, avoiding misoperation caused by device vibration or external interference, making the operation of the transport device stable and reliable.

[0022] Preferably, the diluent bracket is fixed to the upper end of the slider mounting plate.

[0023] Preferably, the diluent bracket comprises a bracket, the micro switch and a bracket cover, the micro switch is welded on the bracket cover, and the micro switch and the bracket cover are assembled together on the outer side of the bracket.

[0024] As the mounting base of the micro switch, the bracket cover not only provides a position for fixing the micro switch, but also plays a protective role to prevent external factors such as dust and moisture from affecting the performance of the micro switch.

[0025] Preferably, the micro switch is arranged in the diluent holder, and the micro switch is used to detect whether the diluent bottle is correctly placed in the diluent holder.

[0026] When the diluent bottle is placed inside the rack, the bottle touches the contact of the micro switch. This contact is designed to be easy to move and sensitive enough to sense slight pressure. Once the micro switch is activated, it sends an electrical signal to the control system, notifying the system that the diluent bottle has been safely placed in place and the transport device can be transported normally.

[0027] In addition, the micro switch also acts as a safety detection function to prevent experimental operation if the diluent bottle is not placed correctly. If the diluent bottle does not trigger the micro switch, the system can automatically stop further operation steps until the operator corrects the placement error. This reduces the risk of possible operator errors.

[0028] Preferably, both left and right sides of the bracket shrink inward to form a first recessed cavity and a second recessed cavity.

[0029] The recessed cavity design facilitates the placement or removal of the diluent bottle, so that the hand can be more naturally inserted into the bracket when placing or removing the diluent bottle, reducing the force required during operation, thereby reducing the risk of possible slippage or misoperation during operation.

DETAILED DESCRIPTION

[0040] As attached Figure 1-Figure 8As shown, the diluent assembly of this embodiment includes a power device, a support device, a transport device, and a diluent bracket. The transport device is arranged on the support device, the power device provides power for the transport device, the diluent bracket is arranged on the upper end of the transport device, a micro switch 10 is arranged in the diluent bracket, a diluent bottle placement place 22 is arranged on the diluent bracket, and the diluent bottle can be pushed in by the transport device for sample injection or / and pushed out for sample removal after touching the micro switch 10.

[0041] like Figure 1 As shown, the support device includes a support plate 2 and a support column 1. The support column 1 is fixed to the lower end of the support plate 2 to provide stable support for the diluent assembly. The transport device is arranged on the support plate 2.

[0042] Specific as Figure 3 As shown, the transport device includes a synchronous belt 4, a driving wheel 12, a driven wheel 5, a linear guide rail 7, a slider 13, a slider mounting plate 14, and a limit device. The fixing screw 11 fixes the linear guide rail 7 to the support plate 2 to ensure that the transport device is firmly connected to the upper surface of the support device. The slider mounting plate 14 is fixed to the upper end of the slider 13 as a transition between the slider 13 and the bracket 9. The lower end surface of the slider 13 is connected to the linear guide rail 7 and slides left and right along the linear guide rail 7. The synchronous belt 4 is attached to the outer periphery of the driving wheel 12 and the driven wheel 5. The power device is a stepping motor 3. The driving wheel 12 is connected to the stepping motor 3 through an inner rod 19. The inner rod 19 is located in the stepping motor 3. The driven wheel 5 is equipped with a driven wheel shaft 6, and the driven wheel shaft 6 is embedded in the support plate 2.

[0043] When in use, the driving wheel 12 is driven to rotate and the synchronous belt 4 is driven to move, so that the slider 13 can move accurately left and right along the linear guide rail 7. The driving wheel 12 is connected and driven by the stepper motor 3 through the inner rod 19. The speed and direction of the stepper motor 3 are adjusted by the control system to meet the requirements of different speeds. The driven wheel 5 plays the role of tensioning the synchronous belt 4 to ensure the stability and synchronization of the synchronous belt 4 during the movement.

[0044] Specific as Figure 6 , Figure 7As shown, the driving wheel 12 is provided with two through holes, namely, the first through hole 20 and the second through hole 21, and the inner rod 19 cooperates with the first through hole 20 and the second through hole 21. The cooperation mode of the inner rod 19 and the two through holes is that the driving wheel 12 passes through the inner rod 19, and the inner rod 19 is provided with a first positioning card 17 and a second positioning card 18. The first positioning card 17 and the second positioning card 18 are respectively matched with the first through hole 20 and the second through hole 21 on the driving wheel 12, and the driving wheel 12 is fixed to the upper end of the inner rod 19. The inner rod 19 plays a key role in transmitting torque. By fixing the driving wheel 12 and the inner rod 19, the coaxial alignment of the driving wheel 12 and the stepper motor 3 is ensured, thereby avoiding unnecessary vibration or deviation generated during the movement process. The stepper motor 3 provides power for the driving wheel 12, and the driving wheel 12 drives the synchronous belt 4 and the driven wheel 5 to rotate through gear meshing. When the synchronous belt 4 rotates, it drives the slider 13 and the slider mounting plate 14 to slide left and right on the linear guide 7.

[0045] Specific as Figure 8 As shown, the limiting device is located below the slider mounting plate 14 , and the limiting device includes an optical coupler 16 and an optical coupler baffle 15 . The optical coupler baffle 15 is connected to the lower end surface of the slider mounting plate 14 and slides together with the slider mounting plate 14 . The optical coupler 16 is fixed on the support plate 2 .

[0046] It should be noted that as the slider mounting plate 14 moves, the optocoupler baffle 15 also moves. When the optocoupler baffle 15 enters the light path of the optocoupler 16 and changes the state of the optocoupler 16, this state change will be detected by the electronic control system, and the system will immediately issue a command to control the stepper motor 3 to stop moving, thereby accurately controlling the position of the slider mounting plate 14 to ensure that it does not exceed the set range of motion, ensuring the safe operation of the device and preventing overshoot and collision during the mechanical process.

[0047] like Figure 1 As shown, a diluent bracket is fixed to the upper end of the slider mounting plate 14 .

[0048] Specific as Figure 4 , Figure 5 As shown, the diluent bracket includes a bracket 9, a micro switch 10, and a bracket cover 8. The micro switch 10 is welded on the bracket cover 8. The micro switch 10 and the bracket cover 8 are assembled together on the outer surface of the bracket 9. The diluent bracket is provided with a micro switch 10, and the micro switch 10 is used to detect whether the diluent bottle is correctly placed in the diluent bracket.

[0049] The specific detection method is that when the diluent bottle is placed in the diluent bottle placement position 22 on the bracket 9, the bottle body will touch the contact of the micro switch 10. After the micro switch 10 is activated, an electrical signal will be sent to the control system, prompting the system that the diluent bottle has been safely placed in place, and the transport device can be transported normally.

[0050] It should be noted that both the left and right sides of the bracket 9 are contracted inward to form a first concave cavity and a second concave cavity, so that when placing or removing the diluent bottle, the hand can be more naturally extended into the bracket 9, reducing the force required during operation, thereby reducing the risk of possible slippage or misoperation during operation.

[0051] The specific embodiments 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 embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
