The placement station is a long groove 11 extending inward, the bottom of the placement station is provided with a through hole, and the lower part of the placement station is provided with a storage bin 12. The long groove 11 of the placement station is adapted to the shape of the flat kit 2; the bottom through hole is used for storing and discarding the flat concave cover 21.

[0032] In combination Figure 3 And Figure 4 As shown in the figure, the kit 2 includes a flat concave cover 21 inside the kit 2, the top of the kit 2 is provided with a through hole, and the through hole is provided with a flat concave cover 21. The nested structure of the flat concave cover 21 and the through hole forms a dustproof seal, which can reduce the contamination rate of the reagent; due to the adoption of the nested structure, the thickness of the flat concave cover 21 can be reduced to reduce the overall height of the kit 2, or increase the storage space of the kit 2 with the same height.

[0033] In combination Figure 5 And Figure 6 As shown in the figure, the outer circle of the flat concave cover 21 is provided with a radial clamping protrusion 21a, the inner circle of the flat concave cover 21 is provided with at least two fan-shaped positioning grooves 21b, and the center of the flat concave cover 21 is provided with a detection hole 21c.

[0034] As shown in the figure Figure 7 The elastic body 42 is arranged between the scraper mechanisms, and each scraper mechanism is connected with adjacent scraper mechanisms by the elastic body 42. The elastic connection between adjacent scrapers 41 ensures the synchronization of the opening and closing of the multi-petal scraper mechanism, and the load of the elastic body 42 arranged in the above manner is automatically balanced, which can improve the coaxiality of the fan-shaped scraper 41 aggregation, prevent gaps in the fan-shaped scraper 41 aggregation, and prevent foam from leaking or accumulating in the gaps.

[0035] As shown in the figure Figure 8As shown, the end bottom of the defoaming assembly 4 is provided with two-limb scraper mechanisms, the opening box assembly 3 is provided with a tapered portion 31 with a taper, the bottom diameter of the tapered portion 31 is smaller than the top diameter, and the scraper mechanisms open and close as the defoaming assembly 4 moves along the tapered portion 31. A single scraper mechanism includes a suspension bracket and a fan-shaped disposable scraper 41, the end bottom of the suspension bracket is provided with a transverse mounting hole, and the two ends of the disposable scraper 41 are provided with buckle structures connected with the mounting hole of the bracket to form a U-shaped structure. The inside of the bracket is provided with a gas supply channel in communication with the mounting hole, and the disposable scraper 41 is a hollow structure, the inside channel of the disposable scraper 41 is in communication with the gas supply channel to form a gas passage. The gap between the suspension brackets of the scraper mechanism is also provided with a high-speed camera 48, which continuously monitors the change of the foam during the working process of the defoaming assembly 4, and identifies the foam thickness and position parameters through gray value analysis. These parameters are fed back to the control system to control the airflow pressure and duration of the air holes 43, so as to realize the precise and efficient defoaming process, and protect the defoaming technology process based on dynamic monitoring and feedback control. The scraper mechanism with multi-limb structure can surround the reagent bottle opening and remove the foam in all directions. At the same time, the defoaming assembly 4 is coaxially sleeved and moves relatively axially, and the scraper mechanism can be opened through the tapered portion 31 to realize the avoidance of the opening box assembly 3, which is beneficial to the integrated design of the defoaming assembly 4 and the opening box assembly 3.

[0036] As shown in Figure 8 The defoaming assembly 4 includes a claw 44 located at the top of the scraper mechanism, the top of the scraper mechanism is provided with a turned edge 46, the claw 44 is provided with a circular arc groove 45 matched with the turned edge 46, and the turned edge 46 can move in the circular arc groove 45 under the action of the elastic body 42 and the tapered portion 31. The gap between the circular arc groove 45 and the turned edge 46 facilitates the opening and aggregation of the scraper mechanism under the action of the elastic body 42, and due to the unstable connection of the circular arc groove 45 and the turned edge 46, the scraper mechanism can flexibly swing or slightly vibrate between the opening and aggregation processes due to the elastic force and inertia of the elastic body 42. The flexible swing can cause a slight impact with the reagent box 2 or the reagent bottle 22, and the foam at the reagent bottle opening can also be broken by the impact vibration. The slight vibration is beneficial to scraping the air bubbles at the reagent bottle opening, and further improves the foam removal effect.

[0037] As shown in Figure 9As shown, the bottom of the scraper mechanism is a fan ring-shaped scraper 41, the inner side of the scraper 41 is a circular arc surface, and the circular arc surface is provided with air holes 43. The fan ring-shaped scraper 41 can be fitted with the shape of the edge of the reagent bottle opening, increasing the area of the foam removed to the edge of the reagent bottle opening; the air holes 43 on the inner side of the scraper 41 have a pore size of 0.3-0.5mm, and 0.2-0.5MPa compressed air is sprayed to form air flow disturbance to make unstable bubbles break, while pushing the relatively stable bubbles in the center of the reagent bottle opening to the edge to collide with the scraper 41 to break, forming mechanical scraping, and the dual defoaming mechanism of air flow disturbance and mechanical scraping can significantly improve the foam removal effect.

[0038] As shown in Figure 10 The end bottom of the box opening assembly 3 includes at least two fan ring-shaped flexible clamping pieces 33, the flexible clamping pieces 33 and the radial clamping protrusions 21a are engaged with each other, and the inside of the flexible clamping pieces 33 is provided with a skeleton of shape memory alloy wire. The radial clamping protrusions 21a and the flexible clamping pieces 33 are engaged with each other, which can improve the clamping force of the box opening assembly 3 on the flat concave cover 21, and avoid slipping when opening the cover; the flexible clamping pieces 33 are combined with shape memory alloy wires made of flexible materials, and when the flexible clamping pieces 33 are engaged with the radial clamping protrusions 21a, the shape memory alloy wires are deformed by controlling the current to make the flexible clamping pieces 33 further clamp the outer circle contour of the flat concave cover 21, thereby maintaining the stability of the clamping force. Through the Joule heating effect of the current, the heat generated by the current makes the temperature of the material rise, and the phase change temperature of the shape memory alloy is controlled to control the deformation of the shape memory alloy wire. In this embodiment, the shape memory alloy wire is a 0.1-0.3mm TiNi wire with a phase change temperature range of-50℃~100℃, a resistance of about 5Ω, a phase change critical temperature of 40℃, and a phase change saturation temperature of 60℃. By applying a current of 0.2-0.4A to the shape memory alloy wire, the temperature in the phase change temperature range can be met.

[0039] The end bottom of the box opening assembly 3 also includes a positioning protrusion 34, and the positioning protrusion 34 and the fan ring-shaped positioning groove 21b are matched with each other. The fan ring-shaped positioning groove 21b and the positioning protrusion 34 cooperate to realize the circumferential positioning of the box opening assembly 3 and the flat concave cover 21, and prevent rotation misplacement.

[0040] The end bottom of the box opening assembly 3 further comprises a detection probe 32 matched with the detection hole 21c, and a displacement sensor 35 is arranged at the end of the detection probe 32 away from the detection hole 21c, and a pressure sensor is arranged inside the detection probe 32. The detection probe 32 is inserted into the detection hole 21c in the center of the flat concave cover 21 when the box opening assembly 3 clamps the flat concave cover 21, and when the flat concave cover 21 is clamped by the flexible clamping piece 33, the pressure sensor inside the detection probe 32 can detect the clamping force, if no pressure or small pressure is detected, it may be clamped failure and need to clamp the flat concave cover 21 again or increase the clamping force, if the detected pressure gradually increases and exceeds the threshold value to avoid damage to the flat concave cover 21, the clamping force of the flexible clamping piece 33 needs to be reduced; since the detection probe 32 is inserted into the flat concave cover 21, the displacement sensor 35 is arranged at the end of the detection probe 32 away from the detection hole 21c, the displacement data of the detection probe 32 is monitored, that is, the displacement data of the detection probe 32 is monitored, to ensure that the flat concave cover 21 is successfully clamped and completely opened under different tightness conditions of the cover.

[0041] In combination with FIGS. 1-4, Figure 8 、 Figure 11 and Figure 12 As shown, the scraper mechanism is provided with a limiting portion 47, and the limiting portion 47 is provided with the same inclination angle as the inclined portion 31 of the scraper mechanism. The limiting portion 47 has a guiding and buffering effect during the upward axial movement of the defoaming assembly 4 relative to the box opening assembly 3; at the same time, the limiting portion 47 further increases the amplitude of the opening and aggregation process of the scraper mechanism.

[0042] Example Two

[0043] For the reagent and its kit stored in the refrigerator, in this embodiment, the enzyme-linked immunoassay kit is taken as an example, and condensate water is easily generated when the cover is opened, and the condensate water drops are easy to contaminate the reagent. For example, Figure 12As shown, the opening box assembly 3 extends to grab the flat concave cover 21, preheats the flat concave cover 21 for a period of time by using the Joule heat of the shape memory alloy wire built-in the flexible clamp 33, and then starts the cover opening and foam removal process, avoiding the condensation of water generated by the low-temperature reagent bottle 22 and the room temperature air, and also preventing the generation of new foam due to the sudden temperature change of the reagent bottle opening. Further, in some embodiments, the TiNi shape memory alloy wire of the flexible clamp 33 adopts two loops and is provided with different diameters, is connected to independent power sources respectively, and a thermocouple is arranged outside the flexible clamp 33 for detecting the clamp temperature. For example, one wire has a diameter of 0.1 mm and a phase change temperature of 40°C, which is used to provide a basic clamping force, and the other wire has a diameter of 0.3 mm and a phase change temperature of 60°C, which is used for auxiliary heating in a low-temperature environment. Through the above arrangement, the problem of unstable clamping force caused by unstable deformation of the shape memory alloy wire when grabbing a low-temperature object is solved; the two shape memory alloy wires are independently controlled, and in the heating process, the metal wire with a lower phase change temperature provides a basic clamping force, and the metal wire with a higher phase change temperature provides an auxiliary clamping force, realizing the phased output of the basic clamping force and the auxiliary clamping force, and reducing the probability of deformation and damage of the flat concave cover 21 due to excessive clamping force.

[0044] Example Three

[0045] For the sterile requirement of molecular diagnosis, on the basis of example one, the disposable scraper adopts pre-sterilized independent packaging, and is still connected through the buckle type detachable connection during use, for example, the positioning pin and the mounting hole cooperate with the suspension type support to quickly assemble. However, the hollow air duct of the support connected with the air hole 43 is sterilized or a filter is added before assembly to avoid pollutants carried by the airflow into the reagent bottle, and a disposable sleeve is arranged outside the detection probe 32 to avoid the detection probe 32 damaging the flat concave cover 21 and causing pollution when the detection probe 32 is in interference fit with the detection hole 21c.

[0046] The present application solves the problem of interference of the foam in the reagent box 2 after opening the cover on the detection process, and the problem of incorrect opening of the cover due to improper placement of the reagent box 2 or different tightness of the flat concave cover 21, and has the following beneficial effects: realizing the full-automatic opening of the flat concave cover 21 of the flat reagent box 2 and the removal of foam at the reagent bottle opening; the dual-foam removal mechanism of airflow disturbance and mechanical scraping can significantly improve the foam removal effect; the unstable connection of flexible swing or slight vibration further improves the foam removal effect; the pressure sensor and displacement sensor 35 are used to monitor the clamping force and clamping displacement, so as to ensure the success of the opening of the cover and the complete opening of the flat concave cover 21.

[0047] The above examples and / or embodiments are merely intended to illustrate the preferred examples and / or embodiments of the present application, and are not intended to limit the embodiments of the present application in any form, and any person skilled in the art can make some changes as other equivalent examples without departing from the scope of the technical means disclosed in the present application, but should be considered as the same technology or embodiments as the present application.
