It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

The biochemical detection is to generate a colored substance through biochemical reaction, the colored substance has absorption effect on light with specific wavelength, and the content of the substance in the biochemical detection item is identified by detecting the absorbance of the light with the wavelength. However, since the diameter of the detection hole of the microfluidic chip is generally in the micrometer scale, it is required to align accurately, avoid spatial crosstalk, and realize motion scanning.

At least one embodiment of the present disclosure provides a detection device, which has the advantages of simple structure, accurate alignment, easy operation and debugging, space saving, and the like.

Fig. 1 is a schematic structural diagram of a detection apparatus according to at least one embodiment of the present disclosure, wherein a detection assembly is located at a first position. Fig. 2 is a schematic structural diagram of a detection device according to at least one embodiment of the present disclosure, wherein a detection assembly is located at a second position. Fig. 3 is a perspective view showing the structure of a detecting unit in the detecting apparatus shown in fig. 1 and 2. Fig. 4 is a side sectional view taken along line a-a' in fig. 3.

As shown in fig. 1 and 2, an inspection apparatus 100 according to at least one embodiment of the present disclosure includes a main body 101, an inspection set 102, and an inspection object receiving part 103.

The sensing assembly 102 is mounted on the body 101. It is to be understood that in fig. 1 and 2, the plate-shaped body 101 is merely exemplary. In other embodiments, body 101 may be any suitable shape and may include any suitable structure, such as a base, a pillar, etc., as embodiments of the present disclosure are not limited in this respect.

The detection target receiving unit 103 is configured to receive a detection target. For convenience of description, the detection object 10 is exemplarily shown in fig. 1 and 2, and the detection object 10 may be, for example, a detection chip including a microfluidic chip, and the detection chip has a detection part (e.g., a detection well) to perform the above-described biochemical detection. The embodiments of the present disclosure do not limit the type, shape, structure, and the like of the detection object 10.

In fig. 1 and 2, the detection object receiving part 103 exemplarily shows limiting columns defining a space for receiving the detection object, however, it should be understood that in other embodiments, the detection object receiving part 103 may further include a detection chip receiving structure for receiving a detection chip, such as a base, a holder, etc., and the embodiment of the present disclosure does not limit the detection object receiving part 103 as long as it can accommodate the detection object (i.e., the detection chip).

The detection object receiving portion 103 and the detection member 102 are provided on the main body 101 to be relatively movable to allow the detection object 10 received by the detection object receiving portion 103 to be located in a transmission path of the detection signal between the signal transmitter and the signal receiver. For example, in some embodiments, the detection assembly 102 is capable of movement and the detection object receiving portion 103 is stationary. For example, in some embodiments, detection assembly 102 is stationary while detection object receiving portion 103 is capable of movement. For example, in some embodiments, both inspection assembly 102 and inspection object receptacle 103 are capable of movement. Hereinafter, embodiments of the present disclosure will be described by taking as an example that the detection member 102 is movable and the detection object receiving portion 103 is fixed. By allowing the detecting member 102 to move and fixing the detecting object receiving portion 103 and the detecting object 10 disposed thereon, the fixing of the detecting object 10 can be facilitated to achieve the accurate control of the micro pump and the micro valve of the detecting object 10.

The detailed structure of the detection assembly according to at least one embodiment of the present disclosure will be described below with reference to fig. 3 and 4. As shown in fig. 3 and 4, the detection assembly 102 includes a signal transmitter, a signal receiver, and a detection connection 1023.

The signal emitter is configured to emit a detection signal. The signal receiver is configured to receive at least a portion of the detection signal emitted by the signal emitter. The detection connection 1023 connects the signal transmitter and the signal receiver, and causes the signal transmitter and the signal receiver to be spaced apart from each other by the detection connection 1023.

Because signal transmitter and signal receiver are connected and fixed by detection connecting portion 1023, the position of both is static relatively from this to avoided the measuring error that relative position error between signal transmitter and the signal receiver caused, reduced the assembly degree of difficulty and increased and detected the precision.

For example, the signal emitter described above may include a light emitting device 1021 to emit a light signal as a detection signal. For example, in some embodiments, the light emitting device 1021 may comprise a light emitting diode.

However, it should be understood that embodiments of the present disclosure are not so limited. For example, in some embodiments, the signal emitter may emit sound waves, microwaves, X-rays, gamma rays, infrared rays, ultraviolet rays, and the like.

For example, in some embodiments, the signal emitter may also include a light collimation component 1024. The light collimating assembly 1024 is configured to collimate the light signal emitted by the light emitting device 1021 into parallel light. For example, the utilization rate of the light signal emitted by the light emitting device 1021 may be increased by collimating the light signal emitted by the light emitting device 1021 by the light collimating assembly 1024, thereby allowing more light signal to pass through the stop 1029 of the detection assembly 102. In some embodiments, the light collimating component 1024 may include one or more convex lenses.

For example, in some embodiments, the light collimating component 1024 can be coupled to the detection connection 1023. For example, the light collimating assembly 1024 may further include a connecting element 1025, the connecting element 1025 including a surface 1025' having threads to enable screwing the light collimating assembly 1024 (e.g., the convex lens described above) to the detection connection 1023.

However, it should be understood that in some embodiments, the signal emitter of the detection assembly 102 may not include the light collimating assembly 1024, thereby reducing the volume of the detection device 100 and providing portability of the detection device 100, as embodiments of the present disclosure are not limited in this respect.

For example, in some embodiments, the signal receiver may include the photoelectric converter 1022. However, it should be understood that in case the signal transmitter transmits other types of detection signals, a corresponding type of signal receiver should also be implemented to be able to receive and process the detection signals.

The photoelectric converter 1022 is configured to convert the received optical signal into an electrical signal and output the electrical signal. For example, the photoelectric converter 1022 may be connected to an analysis instrument and output the converted electric signal to the analysis instrument, and by comparing the light emission intensity of the light emitting device 1021 and the received light intensity of the photoelectric converter 1022, the value of the absorbance of the sample in the detection object 10 may be obtained, thereby obtaining the substance content of the sample in the detection object 10. For example, the light emitting intensity of the light emitting device 1021 can be detected by placing a standard container or a standard in the detection apparatus 100.

For example, in some embodiments, the photoelectric converter 1022 may include a photodiode. For example, the photoelectric converter 1022 may include a silicon photocell.

For example, the detection assembly 102 may include a plurality of light emitting devices 1021 and a plurality of corresponding photoelectric converters 1022, wherein the plurality of light emitting devices 1021 may emit different detection signals (e.g., light signals of different wavelengths), so that the detection apparatus 100 may be used for detecting a plurality of different samples, thereby expanding the application range of the detection apparatus 100.

For example, in some embodiments, the signal receiver described above may further include a filter element 1026. The filter element 1026 is disposed in the transmission path of the detection signal between the signal transmitter and the signal receiver, and allows an optical signal of a set wavelength in the received optical signal to pass through to irradiate the photoelectric converter 1022. Illustratively, the center wavelength of the filter element 1026 may be 550 nanometers. By providing the filter element 1026, stray light can be prevented from being irradiated to the photoelectric converter 1022, and only an optical signal of a set wavelength is allowed, so that the detection accuracy can be improved.

For example, in some embodiments, detection assembly 102 can also include heat sink 1027. Heat sink 1027 is disposed on detection connection 1023 and is thermally coupled to the signal emitter. For example, as shown in fig. 3, a heat sink 1027 is disposed on the detection connection 1023 and is thermally coupled to the signal emitter, in particular to the light emitting device 1021 in the signal emitter. Heat sink 1027 can conduct heat generated by the signal emitter (e.g., light emitting device 1021 of the signal emitter) to the ambient environment, thereby preventing the signal emitter from malfunctioning and even burning out due to overheating.

As shown in fig. 3, in some embodiments, the detection connection 1023 may have a U-shaped structure, a C-shaped structure, or the like. For example, the U-shaped structure allows the test object 10 to be positioned in an opening of the U-shaped structure, and signal emitters (e.g., light emitting device 1021, light collimating assembly 1024, and coupling element 1025) and signal receivers (e.g., photoelectric converter 1022 and filter element 1026) are secured to opposing branches of the U-shaped structure, respectively. In practical applications, the opening and relative position of the U-shaped structure can be adjusted according to the shape of the inspection object 10 to ensure that the inspection portion (e.g., the inspection hole) of the inspection object 10 is aligned with the center of the stop 1029 of the inspection assembly 102.

However, it should be understood that in other embodiments, the detection connection 1023 may have other suitable shapes, and embodiments of the present disclosure are not limited in this regard.

For example, a detection device according to at least one embodiment of the present disclosure may further include a guide rail and a driver, for example, may include one or two guide rails. The guide rail is fixed on the main body, and the detection assembly is movably arranged on the guide rail. The guide rails play a role in restraining, limit the degree of freedom of the detection assembly, only allow the detection assembly to do linear motion, and avoid swinging, for example, two guide rails can have a better stabilizing effect. The driver is in transmission connection with the detection assembly to drive the detection assembly to move along the guide rail.

In fig. 1 and 2, the driver is exemplarily shown in the form of a combination of a rotary motor and a lead screw. The combination form of the rotating motor and the lead screw has the advantages of accurate movement, space saving, low cost and the like. However, it should be understood that embodiments of the present disclosure are not so limited. For example, in other embodiments, the driver may be a linear motor coupled to the sensing assembly to drive the sensing assembly along the rail.

As shown in fig. 1 and 2, the detection apparatus 100 includes a guide rail 104. The above-described driver is implemented to include a motor 105, a lead screw 106, and a nut 107.

The motor 105 is a rotary motor, and has an output shaft. The lead screw 106 is connected to an output shaft of the motor 105 to be rotated by the motor 105. The lead screw 106 is parallel to the guide rail 104. The lead screw 106 may be connected between the motor 105 and the lead screw support 1011, and the lead screw support 1011 is fixed relative to the lead screw 106 and the motor 105. The screw support 1011 may be connected with the main body 101, or the screw support 1011 may be a part of the main body 101, which is not limited by the embodiment of the present disclosure. For example, a bearing can be installed in the lead screw supporting portion 1011, and an inner ring of the bearing can rotate along with the lead screw, so that the lead screw is prevented from bearing unfavorable torque and further inaccurate movement positioning is avoided. However, embodiments of the present disclosure are not limited thereto. The screw support 1011 can be provided to avoid the generation of an adverse torque.

A nut 107 is threadably engaged with the lead screw 106 and movably disposed on the lead screw 106, and the nut 107 is coupled with the detection assembly 102 and can drive the detection assembly 102. The nut 107 is configured to be movable on the screw shaft 106 when the screw shaft 106 is driven to rotate by the motor 105. The nut 107 is slidably coupled to the rail 104, and the rail 104 functions to constrain the nut 107 so that the sensing assembly 102 coupled to the nut 107 can move along the rail 104. Nut 107 may be directly coupled to rail 104, or nut 107 may be coupled to rail 104 via other elements (e.g., sensing assembly 102), as embodiments of the present disclosure are not limited in this respect.

The sensing assembly 102 can be removably coupled to the nut 107 or can be fixedly coupled to the nut 107. The detection assembly 102 may be directly connected to the nut 107, or may be integrally formed with the nut 107, or may be fixedly connected to the nut 107 by other elements, which are not limited by the embodiments of the present disclosure.

For example, a detection device according to at least one embodiment of the present disclosure may further include a position sensor. The position sensor is disposed on the body and configured to generate a position signal for controlling a position or movement of the detection assembly upon detection of the detection assembly.

As shown in fig. 1 and 2, the detection device 100 further includes a position sensor 108. The position sensor 108 may be disposed on the body 101 and configured to generate a position signal upon detection of the detection assembly 102. For example, the position sensor 108 is configured to generate a position signal for the motor 105 when the detection assembly 102 is in the first position as shown in fig. 1. For example, the first position may correspond to an origin position of the motor 105, the position signal is used to reset the motor 105, and the position sensor 108 may send the position signal generated when the detection assembly 102 is in the first position to a controller that controls the motor 105 such that the motor 105 is reset under the control of the controller. By providing the position sensor 108, the origin of the motor 105 can be reset, and thus, the precise positioning of the detecting member 102 can be realized.

For example, the position sensor 108 may be disposed at an end of the rail 104, however, it should be understood that embodiments of the present disclosure are not so limited. In other embodiments, the position sensor 108 may be disposed at any suitable location, depending on the actual requirements.

In the disclosed embodiment, the detection assembly 102 is moved along the guide rail 104 under the drive of the motor 105. The length of the moving stroke of the detecting member 102 can be determined according to actual requirements, for example, according to the width of the region to be detected of the specific detecting object 10 in the moving direction of the detecting member 102. In fig. 1, the detection assembly 102 is in the first position, i.e., the end of its travel away from the motor 105; in fig. 2, the sensing assembly 102 is in a second position, i.e., the end of its travel that is near the motor 105. The detection component 102 may perform fixed point detection or motion scan detection, such as uninterrupted scan detection, on the detected object 10, for example, which is not limited by the embodiments of the present disclosure.

In some embodiments, the position sensor 108 may include a transmitting portion for transmitting the position detection signal and a receiving portion for receiving the position detection signal transmitted by the transmitting portion, and the position sensor 108 may generate the indication signal if the receiving portion does not receive the position detection signal transmitted by the transmitting portion; and in such a case, the sensing assembly 102 can further include a flap 1028 that can be fixedly connected to the sensing assembly 102 for synchronous movement with the sensing assembly 102, and the flap 1028 can be positioned between the emitting portion and the receiving portion of the position sensor 108 when the sensing assembly 102 is in the first position such that the receiving portion of the position sensor 108 cannot receive the sensing signal emitted by the emitting portion, thereby causing the position sensor 108 to generate the position signal. However, it should be understood that the flap 1028 may also be fixedly connected to at least one of the nut 107 or the detection assembly 102, as embodiments of the present disclosure are not limited in this respect.

For example, the position sensor 108 can include a slot-type opto-electronic switch, the flap 1028 can be configured to be received in a slot of the slot-type opto-electronic switch, and the flap 1028 can prevent a signal emitted by a signal emitting end of the slot-type opto-electronic switch from reaching a signal receiving end of the slot-type opto-electronic switch when the flap 1028 is received in the slot of the slot-type opto-electronic switch. The blocking plate 1028 may be formed of any suitable material, such as metal, wood, plastic, etc., as long as the blocking plate 1028 can prevent a signal transmitted from the signal transmitting end of the slot-type photoelectric switch from reaching the signal receiving end of the slot-type photoelectric switch. However, it should be understood that embodiments of the present disclosure are not so limited. For example, in other embodiments, the position sensor 108 may also be a proximity sensor disposed at a first position, and when it detects that the distance from the detection assembly 102 is less than a predetermined value, it is determined that the detection assembly 102 is at the first position.

At least one embodiment of the present disclosure provides a detection method, which is applied to a detection apparatus according to any one of the embodiments of the present disclosure. Fig. 5 is a flow chart of a detection method according to at least one embodiment of the present disclosure.
