For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] See also Figures 1 to 5As shown, a reaction cup grabbing device according to the present application is schematically shown, which is mainly used in immunoassay analyzers such as flow fluorescence and chemiluminescence to grab reaction cups.

[0045] A reaction cup grabbing device provided according to an embodiment of the present application includes: a mounting seat 7100 , an electromagnet 7300 , two clamping claws 7200 and two connecting rods 7400 .

[0046] Among them, the two clamping jaws 7200 are used to grasp the reaction cup, the connecting rod 7400 corresponds to the clamping jaws 7200 one by one, the mounting seat 7100 is provided with a guide mechanism 7150 matched with the two clamping jaws 7200 and a detection switch 7500 for detecting the grasping state, the electromagnet 7300 is arranged on the mounting seat 7100, the electromagnet 7300 has a push rod 7320, the two clamping jaws 7200 are respectively located on both sides of the push rod 7320, the push rod 7320 is hinged to one end of the two connecting rods 7400, and the other end of each connecting rod 7400 is hinged to the corresponding clamping jaw 7200. The push rod 7320 pushes the two clamping jaws 7200 to move synchronously in the opposite direction along the guide mechanism 7150 through the two connecting rods 7400, so that the two clamping jaws 7200 open or hold, that is, clamp or release the reaction cup.

[0047] It should be noted that the electromagnet 7300 may be energized, the push rod 7320 may be retracted, the electromagnet 7300 may be de-energized, and the push rod 7320 may be pushed out; or the electromagnet 7300 may be energized, the push rod 7320 may be pushed out, the electromagnet 7300 may be de-energized, and the push rod 7320 may be retracted.

[0048] In one embodiment of the present application, when the reaction cup needs to be grasped, the electromagnet 7300 is energized, the push rod 7320 is retracted, and the push rod 7320 pushes the two clamps 7200 through the two connecting rods 7400 to move synchronously in the opposite direction along the guide mechanism 7150, so that the two clamps 7200 are opened. When the reaction cup is located at the grasping position between the two clamps 7200, the electromagnet 7300 is de-energized, the push rod 7320 is pushed out, and the push rod 7320 pushes the two clamps 7200 through the two connecting rods 7400 to move synchronously in the opposite direction along the guide mechanism 7150, so that the two clamps 7200 grasp and clamp the reaction cup. At the same time, the grasping state is detected by the detection switch 7500 on the mounting seat 7100 to determine whether the two clamps 7200 have grasped and clamped the reaction cup.

[0049] Therefore, the reaction cup grasping device of the present application adopts the electromagnet 7300 structure to drive the clamp 7200 to clamp or release the reaction cup. It has a simple structure, small size, easy operation, fast response speed, and greatly reduces the cost. The detection switch 7500 can also detect the grasping status to determine whether the reaction cup is grasped and clamped, thereby improving the safety and reliability of the equipment and facilitating better application in immunoassay analyzers such as flow fluorescence and chemiluminescence.

[0050] In some embodiments, the electromagnet 7300 is located above the two clamping jaws 7200, the push rod 7320 is vertically downward, and the guide mechanism 7150 is a linear slide rail 7151 arranged in the vertical direction. Thus, the operation is more convenient, and the structure is more compact and stable.

[0051] Further, the mounting seat 7100 is provided with baffles 7110 respectively matched with the two ends of the linear slide rail 7151. In other words, baffles 7110 are respectively provided at the two ends of the linear slide rail 7151, and the two baffles 7110 limit the slider of the linear slide rail 7151, thereby being safer and more reliable.

[0052] In some embodiments, a first shaft 7310 is disposed on the push rod 7320 of the electromagnet 7300, the first shaft 7310 is disposed in the horizontal direction and is perpendicular to the linear slide rail 7151, two clamping jaws 7200 are respectively hinged to the first shaft 7310, each clamping jaw 7200 is hinged to its corresponding connecting rod 7400 through a second shaft 7410, and the first shaft 7310 is parallel to the second shaft 7410. Thus, the structure is simple, and operations such as installation are more convenient.

[0053] In some embodiments, the mounting seat 7100 is provided with an elastic member 7600 that matches the two clamping jaws 7200. The elastic member 7600 can provide a clamping force for the clamping state of the two clamping jaws 7200. As the two clamping jaws 7200 open, the elastic member 7600 elastically deforms. The elastic member 7600 can be one, two, or more.

[0054] That is to say, the elastic member 7600 acts on the two clamping jaws 7200, and when the two clamping jaws 7200 are opened, the elastic member 7600 is elastically deformed; when the two clamping jaws 7200 grasp the reaction cup, the elastic member 7600 can also push the two clamping jaws 7200 to hold tightly by relying on the elastic restoring force, so that the two clamping jaws 7200 hold tightly toward the middle, ensuring the centering of the two clamping jaws 7200; when the two clamping jaws 7200 grasp and clamp the reaction cup, that is, when the two clamping jaws 7200 are in the holding state, the elastic member 7600 can also provide holding force for the two clamping jaws 7200. In this way, it is ensured that the reaction cup will not fall off accidentally, etc., and the safety, stability and reliability are higher.

[0055] In some embodiments, the elastic member 7600 includes two tension springs 7610, the two tension springs 7610 are in the same direction as the linear slide rail 7151, the tension springs 7610 correspond to the clamping jaws 7200 one by one, one end of each tension spring 7610 is connected to the mounting seat 7100, and the other end of each tension spring 7610 is connected to the corresponding clamping jaw 7200. Thus, the structure is simple and stable, the operation is more convenient and quick, and the two clamping jaws 7200 can be better clamped to the middle.

[0056] Those skilled in the art will appreciate that the elastic member 7600 includes but is not limited to a tension spring 7610 , and may also be a compression spring, an elastic block or other suitable elastic structure.

[0057] In some embodiments, a connecting plate 7120 is provided on the mounting seat 7100, and a first connecting column 7130 connected to two tension springs 7610 is provided on the connecting plate 7120, and a second connecting column 7240 connected to the corresponding tension spring 7610 is provided on each clamping jaw 7200. Hooks are usually provided at both ends of the tension spring 7610, and hook grooves, holes or annular grooves connected to the hooks of the tension spring 7610 can be provided on the first connecting column 7130 and the second connecting column 7240. As a result, the structure is simpler, and the operation is more convenient and quicker.

[0058] In some embodiments, two tension springs 7610, a first connection column 7130 and two second connection columns 7240 are respectively located below the mounting base 7100, and an upper end of one of the clamping jaws 7200 is provided with an inclined portion 7210 that is inclined upward in a direction away from the other clamping jaw 7200, so that an interval 7700 is formed between the upper ends of the two clamping jaws 7200, and the first connection column 7130 corresponds to the interval 7700. Thus, the operation is more convenient, and the interval 7700 ensures that the two tension springs 7610 have enough stretching space, so that the two tension springs 7610 can better act on the two clamping jaws 7200, which is more stable and reliable.

[0059] In some embodiments, each clamping jaw 7200 is provided with an arc groove 7230, which is arranged in the vertical direction and passes through the bottom of the clamping jaw 7200, and the two arc grooves 7230 cooperate to clamp the reaction cup.

[0060] That is to say, when the two clamping jaws 7200 grab the reaction cup, the two arc grooves 7230 cooperate to clamp the reaction cup, thereby ensuring a more stable clamping of the reaction cup, and the top of the arc groove 7230 can also limit the top of the reaction cup, which is safer and more reliable.

[0061] In some embodiments, a calibration column 7220 is disposed at the bottom of one of the clamping jaws 7200 . The calibration column 7220 is a conductive metal and is electrically connected to a corresponding detector. The calibration column 7220 is used to calibrate the grasping position.

[0062] When the two clamps 7200 grab a reaction cup from a corresponding device, such as a heating device, a magnetic cleaning device, a detection device or a mixing device of an immunoassay analyzer, the grabbing position is first calibrated by the calibration column 7220, the calibration column 7220 cooperates with the sensing element of the grabbing position, and the detector connected to the calibration column 7220 feeds back the signal to the corresponding control system, and then adjusts the position of the two clamps 7200, and then controls the two clamps 7200 to grab the reaction cup accurately and efficiently. As a result, the operation is more convenient, more accurate, more efficient, more stable and more reliable.

[0063] In some embodiments, the detection switch 7500 is a slot-type optical coupling sensor 7510, wherein a sensing sheet 7250 corresponding to the slot-type optical coupling sensor 7510 is disposed on one of the clamping jaws 7200, and a slot body 7251 is disposed on the sensing sheet 7250. The sensing sheet 7250 may adopt an L-shaped structure. When the two clamping jaws 7200 are in a state of gripping the reaction cup, the slot body 7251 of the sensing sheet 7250 corresponds to the detection slot of the slot-type optical coupling sensor 7510. When the two clamping jaws 7200 are in an open state, an initial state (i.e., a non-working state), or a state of not gripping the reaction cup, the slot body 7251 of the sensing sheet 7250 does not correspond to the detection slot of the slot-type optical coupling sensor 7510.

[0064] For example, Figure 5 For reference, in the initial state of the two clamping jaws 7200, the groove body 7251 of the sensing sheet 7250 is located on the right side of the detection groove of the groove-type optical coupling sensor 7510; when the reaction cup needs to be grasped, the groove-type optical coupling sensor 7510 is triggered, and the two clamping jaws 7200 first move in the opposite direction to the open state synchronously, at which time the groove body 7251 of the sensing sheet 7250 is located on the left side of the detection groove of the groove-type optical coupling sensor 7510; when the two clamping jaws 7200 grasp the reaction cup, the groove body 7251 of the sensing sheet 7250 is located on the left side of the detection groove of the groove-type optical coupling sensor 7510. 7251 corresponds to the detection slot of the slot-type optical coupling sensor 7510, that is, the slot body 7251 of the sensing sheet 7250 is located in the detection slot of the slot-type optical coupling sensor 7510. At this time, the slot-type optical coupling sensor 7510 is not triggered, that is, it is determined that the reaction cup is grasped and clamped; if the two clamping jaws 7200 do not grasp the reaction cup, the two clamping jaws 7200 return to the position of the initial state, and at this time, the slot body 7251 of the sensing sheet 7250 is located on the right side of the detection slot of the slot-type optical coupling sensor 7510. Therefore, the structure is simple, the response speed is fast, and it is possible to quickly determine whether the two clamping jaws 7200 grasp and clamp the reaction cup, and the efficiency is higher.

[0065] Those skilled in the art will appreciate that the detection switch 7500 may be one, two or more detection switches, and the detection switch 7500 includes but is not limited to a slot-type optical coupler sensor 7510. The detection switch 7500 may also be a proximity switch or other types of photoelectric sensors.

[0066] In some embodiments, the mounting base 7100 is provided with a wiring port 7140, and the electromagnet 7300 and the detection switch 7500 are connected to the wiring port 7140 through wires. The wiring port 7140 is used to connect to other external devices, such as the wiring port 7140 can be connected to a power supply, a control system of an immunoassay analyzer, etc. Thus, the operation is more convenient, faster, safer and more reliable.

[0067] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0068] The above are only some embodiments of the present application, which are only used to illustrate the technical solution of the present application, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present application, it is possible to improve or replace it according to the above description, and all these improvements and replacements should belong to the protection scope of the claims attached to the present application.
