Through applying the amplification plate assembly of this embodiment, the amplification plate assembly includes the amplification plate body 10 and the frame structure 20; the frame structure 20 is provided with the mounting opening 211; and the mounting opening 211 is sealed with the sealing film, and the sealing film is disposed opposite to the plurality of accommodating grooves 11. The sealing film can be adhered on the amplification plate body 10 through hot-pressing of a hot-pressing film machine and seals the plurality of accommodating grooves 11, such that detection samples in the accommodating grooves are prevented from overflowing. In addition, the frame structure 20 is further provided with the insertion portion 31, and the amplification plate body 10 is provided with the first cooperating portion and the second cooperating portion 33, which are respectively cooperated with the insertion portion 31. When the amplification plate assembly is transported, the insertion portion 31 may be cooperated with the first cooperating portion in the inserting manner, and in this case, there is a predetermined distance between the sealing film and the amplification plate body 10, such that the sealing film and the amplification plate body 10 are prevented from scratching due to shaking during transportation, thereby effectively reducing the probability of sealing film damage. When the accommodating grooves 11 need to be sealed, the insertion portion 31 may be cooperated with the second cooperating portion 33 in the inserting manner, and in this case, the sealing film is attached to the upper surface of the amplification plate body 10, such that the sealing film may be heated by the hot-pressing film machine, so as to adhere the sealing film on the amplification plate body 10, thereby achieving sealing of the accommodating grooves 11.

It is to be noted that, the area of the first inserting hole 40 is less than the area of the second inserting hole 50. Since the frame structure 20 has two covering states, the second inserting hole 50 is designed with a larger area, such that when the insertion protrusion 311 on the frame structure 20 is cooperated with the first inserting groove 321, an overlapping area between the first inserting hole 40 and the second inserting hole 50 is large enough, and therefore, the clamping jaw can simultaneously extend into the first inserting hole 40 and the second inserting hole 50 when the insertion protrusion 311 is cooperated with the first inserting groove 321, so as to grab the entire amplification plate assembly. Correspondingly, when the insertion protrusion 311 on the frame structure 20 is cooperated with the second inserting groove 331, there is also a large overlapping area between the second inserting hole 50 and the first inserting hole 40, such that the clamping jaw simultaneously extends into the first inserting hole 40 and the second inserting hole 50.
Specifically, as shown in
As shown in
It is further to be noted that, in this embodiment, an upper edge of the second inserting hole 50 is longer than an upper edge of the first inserting hole 40. In addition, in this embodiment, the clamping jaw is formed by a plurality of clamping blocks, and the plurality of clamping blocks may be close to or far away from each other. When the frame structure 20 is grabbed, there is a large distance among the plurality of clamping blocks, so as to ensure that the clamping blocks can only extend into the second inserting holes 50 but does not extend into the first inserting holes 40, thereby achieving the clamping of the frame structure 20. When the entire amplification plate assembly is grabbed, there is a small distance among the plurality of clamping blocks, such that the clamping blocks can simultaneously extend into the first inserting holes 40 and the second inserting holes 50, thereby achieving the clamping of the entire amplification plate assembly.
It is to be noted that, a consumable material for nucleic acid detection further includes a nucleic acid detection extraction plate. The nucleic acid detection extraction plate is a 96-well plate, of which size is greater than the amplification plate assembly, such that the length of the amplification plate assembly may be set to a size equal to the width of the nucleic acid detection extraction plate.
The inserting holes into which the clamping jaw of the grabbing apparatus extends is disposed in the length direction of the amplification plate assembly, and an inserting hole of the nucleic acid detection extraction plate is disposed in a width direction of the nucleic acid detection extraction plate, such that the nucleic acid detection extraction plate and the amplification plate assembly are grabbed by the same grabbing apparatus, thereby improving the universality of the amplification plate assembly.

The present disclosure further provides a method for detecting a state of an amplification plate assembly. The amplification plate assembly is the above amplification plate assembly. The method for detecting the state of the amplification plate assembly includes: moving the amplification plate body 10, so as to cause the amplification plate body 10 to close to a connecting line of a signal transmitter and a signal receiver, and cause the first long edge of the amplification plate body 10 to have a first predetermined distance H1 from the connecting line of the signal transmitter and the signal receiver; and estimating whether the signal receiver receives a signal transmitted by the signal transmitter, if the signal receiver is capable of receiving the signal transmitted by the signal transmitter, estimating that the frame structure does not cover the amplification plate body 10, and if the signal receiver does not receive the signal transmitted by the signal transmitter, estimating that the frame structure covers the amplification plate body 10.
The above solution provides the method for detecting the state of the amplification plate assembly. Specifically, the amplification plate body 10 may be moved to a position close to a signal transmission line of the signal transmitter and the signal receiver, and the first long edge of the amplification plate body 10 has the first predetermined distance H1 from the signal transmission line of the signal transmitter and the signal receiver. Then, estimating whether the signal receiver receives the signal transmitted by the signal transmitter, if the signal receiver is capable of receiving the signal transmitted by the signal transmitter, it indicates that there is no object blocking the signal, such that the frame structure 20 does not cover the amplification plate body 10. If the signal receiver does no receive the signal transmitted by the signal transmitter, it indicates that the signal is blocked by the frame structure 20, such that it may be estimated that the frame structure covers the amplification plate body 10. Through the above solution, a covering state of the amplification plate assembly may be estimated through the signal transmitter and the signal receiver, such that a subsequent film sealing operation may be conveniently performed on the amplification plate assembly.
When the insertion portion 31 is cooperated with the second cooperating portion 33, the distance of the frame structure 20 protruding from the first long edge of the amplification plate body 10 is L1; and when the insertion portion 31 is cooperated with the first cooperating portion 32, the distance of the frame structure 20 protruding from the first long edge of the amplification plate body 10 is L4. As shown in
It is to be noted that, the first predetermined distance H1 is less than a distance of the frame structure 20 protruding from the first long edge of the amplification plate body 10. Herein, the distance of the frame structure 20 protruding from the first long edge of the amplification plate body 10 refers to the smaller one of L1 and L4, that is, the distance above refers to L4.
The signal transmission line refers to a transmission path from the signal transmitted by the signal transmitter to the signal received by the signal receiver, and may be a straight connecting line formed between the signal transmitter and the signal receiver in an opposing optocoupler; and the signal transmitter and the signal receiver in a reflective optocoupler may also be located on the same end, and the signal receiver receives the signal by receiving reflected light.
The present disclosure further provides a method for detecting a state of an amplification plate assembly. The amplification plate assembly is the above amplification plate assembly. The method for detecting the state of the amplification plate assembly includes: moving the amplification plate body 10, so as to cause the first long edge of the amplification plate body 10 to close to a signal transmission line of a signal transmitter and a signal receiver, and cause the first long edge of the amplification plate body 10 to have a second predetermined distance H2 from the signal transmission line of the signal transmitter and the signal receiver; and estimating whether the signal receiver receives a signal transmitted by the signal transmitter, if the signal receiver is capable of receiving the signal transmitted by the signal transmitter, estimating that the frame structure does not cover the amplification plate body 10, and if the signal receiver does not receive the signal transmitted by the signal transmitter, estimating that the insertion portion 31 is cooperated with the second cooperating portion 33 in the inserting manner.
In the above solution, through the signal transmitter and the signal receiver, not only the covering state of the amplification plate assembly can be estimated, but also the specific cooperating portion with which the insertion portion 31 on the frame structure is cooperated can be estimated. Specifically, when the insertion portion 31 is cooperated with the second cooperating portion 33 in the inserting manner, a distance L1 of the frame structure 20 protruding from the first long edge of the amplification plate body 10 is greater than a distance L2 of the frame structure 20 protruding from the second long edge of the amplification plate body 10, such that the second predetermined distance H2 may be set to meet the following condition: L2<H2<L1. When the signal transmitted by the transmitter is blocked by the frame structure, it indicates that the insertion portion 31 is cooperated with the second cooperating portion 33 in the inserting manner, that is, the sealing film of the frame structure is attached to the amplification plate body 10.
The present disclosure further provides a method for detecting a state of an amplification plate assembly. The amplification plate assembly is the above amplification plate assembly. The method for detecting the state of the amplification plate assembly includes: moving the amplification plate body 10, so as to cause the second long edge of the amplification plate body 10 to close to a signal transmission line (which is also a connecting line of a signal transmitter and a signal receiver) of the signal transmitter and the signal receiver, and cause the second long edge of the amplification plate body 10 to have a third predetermined distance H3 from the signal transmission line of the signal transmitter and the signal receiver; and estimating whether the signal receiver receives a signal transmitted by the signal transmitter, if the signal receiver is capable of receiving the signal transmitted by the signal transmitter, estimating that the frame structure does not cover the amplification plate body 10, and if the signal receiver does not receive the signal transmitted by the signal transmitter, estimating that the insertion portion 31 is cooperated with the first cooperating portion 32 in the inserting manner.
In the above solution, through the signal transmitter and the signal receiver, not only the covering state of the amplification plate assembly can be estimated, but also the specific cooperating portion with which the insertion portion 31 on the frame structure is cooperated can be estimated. Specifically, when the insertion portion 31 is cooperated with the first cooperating portion 32 in the inserting manner, a distance L3 of the frame structure 20 protruding from the second long edge of the amplification plate body 10 is greater than a distance L4 of the frame structure 20 protruding from the first long edge of the amplification plate body 10, such that the third predetermined distance H3 may be set to meet the following condition: L4<H3<L3. When the signal transmitted by the transmitter is blocked by the frame structure, it indicates that the insertion portion 31 is cooperated with the second cooperating portion 33 in the inserting manner, that is, there is a predetermined distance between the sealing film of the frame structure and the amplification plate body 10.
It is to be noted that, in the above implementation, the signal transmitted by the signal transmitter is a laser signal. The signal transmitter and the signal receiver are both fixedly disposed.
Detection cooperation between the amplification plate assembly and the signal transmitter and the signal receiver are achieved by moving the amplification plate assembly. In other implementations, the signal transmitter and the signal receiver may also be movably disposed, and the amplification plate assembly is fixedly placed, such that detection and cooperation are achieved by moving the signal transmitter and the signal receiver.
In the description of the present disclosure, it is to be understood that, terms such as “front, rear, up, down, left or right”, “transverse, longitudinal, vertical, or horizontal”, “top or bottom”, and the like are usually based on the orientation or positional relationships shown in the drawings and are used only to facilitate and simplify the description of the present disclosure. In the absence of any indication to the contrary, these orientation words do not indicate and imply that the device or component referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be construed as limiting the scope of protection of the present disclosure. The orientation word “inside or outside” refers to the inside and outside relative to the contours of the components themselves.
For ease of description, spatially relative terms such as “on . . . ”, “above . . . ”, “on an upper surface of . . . ”, “upper”, and the like may be used here to describe the spatial position relationship between a device or feature and other devices or features as shown in the figure. It is to be understood that, the spatially relative terms are intended to cover different orientations in use or operation other than the orientation of the device described in the figure. For example, if the devices in the drawings are inverted, the devices described as “above” or “on” other devices or configurations will later be positioned as “below” or “under” other devices or configurations. Therefore, the exemplary term “above . . . ” may include both orientations of “above . . . ” and “below . . . ”. The device may also be positioned in other different ways (rotating 90 degrees or in other orientations), and the spatially relative descriptions used here are explained accordingly.
In addition, it is to be noted that, the use of words such as “first” and “second” to limit the parts is only to facilitate the distinguishing of corresponding parts, if not otherwise stated, the above words do not have a special meaning, and therefore cannot be understood as a limitation of the scope of protection of the present disclosure.
