Alternatively, as shown in fig. 2 and 5, the card moving assembly 14 includes a rotary disc 142 coaxial with the incubation disc 12 and sleeved with the incubation disc 12, and a rotary shaft 141 connected with the rotary disc 142, where the rotary shaft 141 is connected with the driving assembly 13 to drive the rotary disc 142 to rotate under the driving of the driving assembly 13, a pre-storing clamping position 143 is arranged on the rotary disc 142 along the radial direction of the rotary disc 142, and a driving member 144 is fixedly arranged on the rotary disc 142, and when the pre-storing clamping position 143 is the same as the extending direction of the slot 121, the driving member 144 drives the reagent card to move between the pre-storing clamping position 143 and the slot 121.

The card moving assembly 14 comprises a rotary table 142 which is coaxial with the incubation tray 12 and sleeved with the incubation tray 12, and the rotary table 142 and the incubation tray 12 are arranged in a coplanar mode, so that a pre-stored clamping position 143 and a groove 121 are located at the same height, a rotary shaft 141 is connected with a driving piece 144, the driving piece 144 drives the rotary shaft 141 to rotate, the rotary table 142 is driven to rotate, and when the rotary table 142 is in the same extension direction of the pre-stored clamping position 143 and one groove 121, the driving piece 144 drives a reagent card to be transferred between the pre-stored clamping position 143 and the groove 121.

Specifically, the driving component 13 drives the rotating shaft 141 to rotate and drives the turntable 142 to rotate, so that when the extending direction of the pre-storing clamping position 143 and the extending direction of the temporary storing position 122 are the same, the driving piece 144 drives the reagent card to be transferred from the temporary storing position 122 to the pre-storing clamping position 143, then the turntable 142 rotates under the driving of the driving component 13, so that the extending direction of the pre-storing clamping position 143 and the dripping level 123 is the same, the driving piece 144 drives the reagent card to be transferred from the pre-storing clamping position 143 to the dripping level 123 to finish the transfer from the temporary storing position 122 to the dripping level 123, and the transfer from the dripping level 123 to the incubating position 125 to the detecting position 124 is finished.

In order to simplify the structure of the reagent card incubation apparatus 10, the incubation plate 12 is configured in a ring shape, and the turntable 142 is disposed in an area surrounded by the ring shape, as shown in fig. 2 and 3.

In one implementation of this embodiment, the driving member 144 is further configured to push the reagent card located in the fixing slot 121 out of the other end of the fixing slot 121 to remove the card when transferring the reagent card to the fixing slot 121.

The fixed slot 121 is a slot 121, and in order to improve the detection flux of the reagent card incubation apparatus 10, after detection is completed, the card is directly unloaded from the detection position 124, that is, the fixed slot 121 is the detection position 124, after the detection of the first reagent card is completed, the first reagent card is placed in the detection position 124, until the incubation of the second reagent card is completed, when the second reagent card is transferred to the detection position 124, the front end of the second reagent card will abut against the rear end of the first reagent card, and in the process of transferring the second reagent card, the first reagent card gradually exits from the other end of the detection position 124 from the detection position 124, thereby realizing the unloading of the first reagent card. According to the embodiment of the application, the second reagent card is adopted to push the first reagent card to realize the card unloading of the first reagent card, so that a card unloading assembly in the prior art can be reduced, the components of the reagent card incubation device 10 are reduced, the structure of the reagent card incubation device 10 is simplified, meanwhile, the card unloading time is not required to be reserved, the detection time of the reagent card is shortened, and the flux of an immunochromatography analyzer is improved.

Alternatively, as shown in fig. 2, the slot 121 is disposed on a side of the incubation plate 12 near the base 11, the card moving assembly 14 is disposed inside the base 11, and the driving assembly 13 is disposed on a side of the incubation plate 12 far from the base 11.

In practical applications, the base 11 is usually disposed on a rack of an immunochromatographic analyzer, so that one side of the incubation tray 12 where the slot 121 is disposed is downward, the card moving assembly 14 must be disposed inside the base 11 to implement a function of transferring a reagent card, and the driving assembly 13 is disposed on the other side of the incubation tray 12 due to limited space inside the base 11, so as to implement effective utilization of space and reduce space occupied by the reagent card incubation device 10.

As can be seen from the above, the side of the incubation plate 12 with the groove 121 is downward, so that the reagent card is prevented from falling under the action of gravity. In addition, a limiting portion may be formed by protruding from two sides of one side of the slot 121 near the base 11 toward the center, and a sliding channel between the two limiting portions is used for making the card moving assembly 14 move the card, where the limiting portion limits the reagent card in the vertical direction.

In one implementation manner of the embodiment of the present application, as shown in fig. 5, the driving member 144 drives the reagent card through the card pushing member 145 disposed on the turntable 142, the card pushing member 145 is provided with push rods 146 extending into the pre-stored card 143 along two ends of the extending direction of the pre-stored card 143, and the card pushing member 145 is driven to drive the push rods 146 at two ends to push the reagent card to enter the pre-stored card 143 from one slot 121 or to enter another slot 121 from the pre-stored card 143.

Specifically, when the extending direction of the pre-storing position 143 is the same as that of the temporary storing position 122, at this time, the push rod 146 of the push card 145 away from the center of the disc abuts against the outer side wall of the reagent card in the temporary storing position 122, the driving member 144 drives the push card 145 to move from the temporary storing position 122 to the pre-storing position, so that the push rod 146 drives the reagent card to move into the pre-storing position 143 when moving inwards, the reagent card is transferred from the temporary storing position 122 to the pre-storing position 143, at this time, the push card 145 returns to the starting point, then the turntable 142 rotates under the driving of the driving assembly 13, so that the extending direction of the pre-storing position 143 is the same as that of the dripping position 123, at this time, the push rod 146 of the push card 145 close to the center of the disc abuts against the inner side wall of the reagent card in the temporary storing position 122, and the driving member 144 drives the push card 145 to move outwards again, so that the push rod 146 drives the reagent card to move into the dripping position 123 when moving outwards, and the reagent card is transferred from the pre-storing position 143 to the dripping position 123, so that the transfer of the temporary storing position 122 to the dripping position 123 is completed, and the transfer of the dripping position 123 to the incubating position 125 is completed, and the transfer of the incubating position 125 to the detecting position 124 is completed.

Because of the long incubation time of the reagent card, after the reagent card is transferred from the dripping level 123 to the incubation position 125, the driving member 144 drives the card pushing member 145 to return to the zero position along the circumferential movement of the incubation plate, and then other reagent cards are transferred.

Optionally, as shown in fig. 5, a first photo detector facing the card pushing member 145 is disposed on the turntable 142, for sensing a position of the card pushing member 145 relative to the turntable 142, and a second photo detector is disposed in the pre-storing position 143, for sensing a state of the pre-storing position 143.

The first photoelectric detector is used for sensing the position of the push-clamping piece 145 relative to the turntable 142, and as can be seen from the above, the push-clamping piece 145 is used for transferring the reagent card from the pre-stored clamping position 143 to the groove position 121, or transferring the reagent card from the groove position 121 to the pre-stored clamping position 143, so that the push-clamping piece 145 has two positions relative to the turntable 142, one is a starting point position close to the turntable 142, and the other is a final point position far from the turntable 142, and the first photoelectric detector is used for sensing whether the push-clamping piece 145 is located at the starting point position or the final point position, thereby being capable of instantly judging the state of the push-clamping piece 145 and improving the working efficiency of the push-clamping piece 145. In order to detect two states of the card pushing member 145, the first photo detector includes two photo detectors, which are respectively used for detecting a start point position and an end point position, so as to accurately determine the position state of the card pushing member 145.

The second photoelectric detector is arranged in the pre-stored clamping position 143 and is used for sensing whether the pre-stored clamping position 143 contains a reagent card or not so as to judge the state in the pre-stored clamping position 143 in real time.

The card moving assembly 14 includes a plurality of elements, the elements need to be electrically connected and/or signal connected with the outside, in order to form a wiring channel, the inside of the rotating shaft can be set to be hollow, and the power lines and/or signal lines of the elements pass through the hollow of the rotating shaft to realize the electrical connection and/or signal connection.

In one implementation manner of the embodiment of the present application, as shown in fig. 1 and 6, the driving assembly 13 includes an encoder motor, a rotation shaft of the encoder motor is connected with the rotation shaft 141 through a synchronous pulley, a bearing seat 15 is disposed on a side surface of the incubation plate 12 far away from the base 11, and the rotation shaft 141 passes through the bearing seat 15 and is connected with the synchronous pulley.

When the drive assembly 13 includes an encoder motor, the positioning of the turntable 142 can be performed without repeated changes, thereby reducing reagent card transfer time, further improving reagent card detection efficiency, and improving the detection throughput of the reagent card incubation apparatus 10.

The encoder motor and the turntable 142 are arranged in a staggered manner through the synchronizing wheel, a frame body is arranged on the incubation plate 12 to fix the encoder motor, in addition, in order to fix the turntable 142, a fixing plate is arranged, the fixing plate is simultaneously connected with the turntable 142 and the incubation plate 12, and a bearing seat 15 is arranged on the fixing plate to support the synchronizing wheel.

Alternatively, as shown in fig. 4, the slot 121 includes a plurality of temporary storage locations 122, a drip level 123, a detection location 124, and a plurality of incubation locations 125, where the drip level 123 and the incubation locations 125 are provided with a blocking portion 16 at an end remote from the center of the incubation tray 12.

Because the drip level 123 and the detection level 124 are used for drip and detection, respectively, the operation time is short, and the incubation level 125 is used for incubation, which requires a long time, the embodiment of the present application sets the slot 121 to a plurality of temporary storage levels 122, one drip level 123, one detection level 124 and a plurality of incubation levels 125.

The temporary storage position 122 and the detection position 124 need to enter the card from one end of the slot position 121 and unload the card from the other side of the slot position 121, so the slot position 121 of the temporary storage position 122 and the detection position 124 is a through slot, the drop level 123 and the incubation position 125 need to enter the card from one end and take the card from the same end, so, in order to avoid that the reagent card slides out of the drop level 123 and the incubation position 125 from one end of the drop level 123 and the incubation position 125 far away from the center of the incubation plate 12, the blocking part 16 is arranged at one end of the drop level 123 and the incubation position 125 far away from the center of the incubation plate 12, so as to avoid the sliding out of the reagent card.

The number of the temporary storage sites 122 and the incubation sites 125 is not specifically limited in this embodiment, and a person skilled in the art can set according to actual incubation conditions and incubation time, and, in addition, the temporary storage sites 122 and the incubation sites 125 are used for placing reagent cards, so that when the incubation sites 125 are not enough in practical use, incubation in the temporary storage sites 122 can be adopted.

In addition, in order to further limit the dripping level 123 and the incubation position 125, the widths of the dripping level 123 and the incubation position 125 of the groove 121 can be set smaller, so long as the reagent card can be ensured to smoothly enter, on one hand, the reagent card can be prevented from sliding out, and the position of the reagent card can be accurately limited, because the dripping level 123 needs to drip the reagent card into the reaction liquid, the consistency of the dripping position can be ensured by accurately determining the reagent card; similarly, the detection bit 124 needs to scan and detect the reagent card, and the accurate positioning of the reagent card can ensure the detection accuracy.

The heat conducting plate 182 can homogenize the heat generated by the heating plate, so that the temperature in the constant temperature chamber is uniform, and the problem that the incubation time cannot be controlled due to the fact that the temperature difference of the constant temperature chamber is large is avoided. In addition, the heat conducting plate 182 made of high heat conducting material can transfer heat quickly, so that the temperature in the constant temperature chamber reaches the preset temperature range quickly after the power-on.

In one implementation manner of the embodiment of the present application, as shown in fig. 7, the heating plate 181 is a semiconductor heating plate, and the cooling surface of the semiconductor heating plate is further connected to a heat dissipation component 183, where the heat dissipation component 183 passes through the housing and is communicated with the outside.
