[0058] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0059] like Figure 1-5As shown, an imaging device according to this embodiment includes a housing 100. The housing 100 includes a first chamber 110, which is a darkroom space and is configured to be openable or closed. An imaging assembly 500 is disposed within the first chamber 110. The imaging assembly 500 is used to convert the optical signal generated by the detected sample into an image. The housing 100 also includes a second chamber 120, which is located below the first chamber 110. A control motherboard 600 is disposed within the second chamber 120. The control motherboard 600 is signal-connected to the imaging assembly 500. The housing 100 is also provided with an external port 400, which is electrically connected to the control motherboard 600 and is used to enable the imaging device to be operably connected to an external device. The optical signal emitted by the biological sample membrane is received by the pixel array within the detection area of ​​the imaging assembly 500, and is converted into an electrical signal by the pixel array, thereby outputting image information. By providing a control mainboard 600, the imaging device can be operatively connected to external devices, enabling real-time debugging of the imaging device based on the displayed image, facilitating adjustment of various parameters, and allowing the operator to select an appropriate operating mode based on their operating habits or operating environment. The control mainboard 600 can control the imaging device's imaging component 500 and other hardware devices, and provides a lower-level operating system to facilitate operative connection with external devices.

[0060] The side length of the pixel array of imaging assembly 500 can be selected as needed, ranging from 60 mm to 160 mm. Since most biological sample membranes are larger than 60 mm, setting the side length of the pixel array between 60 and 160 mm allows the imaging device to be adapted for biological sample membranes of various sizes without making the imaging assembly excessively large and costly. The size of the pixels forming the pixel array can be selected as needed, ranging from 25 μm to 200 μm, ensuring image resolution while improving light collection efficiency and electron capacity.

[0061] The biological sample membrane to be imaged is a polymer membrane or gel block carrying biomacromolecules that are capable of fluorescing when excited by excitation light. The polymer membrane or gel block carrying biomacromolecules can be a PVDF membrane carrying a protein sample, a nitrocellulose membrane carrying a protein test sample, or a gel block carrying DNA / RNA or a gel block carrying a protein.

[0062] In this embodiment, the external port 400 includes an interface for connecting to a mouse and a keyboard. By providing a mouse and keyboard connection port, it is convenient for the staff to debug the imaging device, transmit data, or adjust the imaging parameters of the imaging device through the mouse and keyboard. The external port 400 also includes a power interface, through which the imaging device is powered. Specifically, an interface board 700 is provided in the second chamber 120. The interface board 700 is integrated with an external interface (such as an HDMI interface, a VGA interface, a USB interface, etc.), a power interface, a network cable interface, etc. The interface board 700 is connected to the control main board 600.

[0063] In this embodiment, the imaging device further includes a touch screen 300, which is connected to a control board 600. The touch screen 300 controls the control board 600 and can display imaging results as required, so that imaging parameters can be adjusted to obtain the best imaging effect.

[0064] As shown in the figure, the touch screen 300 and the external connection port 400 are arranged on two opposite sides of the housing 100. The above structural design can avoid interference of external wires on the touch screen 300 when an external device is connected.

[0065] The imaging device of this embodiment is provided with a touch screen 300 and external interfaces for a mouse and a keyboard, so that the user has an additional operation path to choose from during operation, and can select a suitable operation method according to the operation environment or operation habits.

[0066] As shown in the figure, a cover 200 is hingedly attached to the housing 100, and the first chamber 110 is opened or closed by the cover 200. A backlight assembly is provided on the inner top surface of the cover 200, which provides a light source for the imaging assembly 500. This structural design allows the darkroom to be opened and closed, facilitating the placement of a biological sample membrane to be imaged within the darkroom. The light source on the backlight assembly facilitates the imaging assembly 500 to acquire signals from the biological sample membrane to obtain an image.

[0067] The control mainboard 600 is connected to the power supply on the backlight assembly and is used to control the brightness of the light source. When the imaging device is in use, the brightness of the light source can be controlled to obtain the best imaging image for subsequent analysis.

[0068] The backlight assembly is integrated with a dot-shaped LED array (not shown). The LEDs are evenly spaced to achieve uniform illumination. For even better illumination, other light sources can be used, such as tube lamps, solid-state laser emitters, or gaseous laser emitters. The illumination duration of the LEDs, when turned on, ranges from 10ms to 1000ms, and can be adjusted based on actual needs.

[0069] In some embodiments, a diffuser plate (not shown in the figure) is further provided on the backlight panel assembly. The diffuser plate is fixed directly below the LED lamp bead array, so that the light emitted by the LED lamp bead array is more uniform, thereby improving the imaging effect.

[0070] In some embodiments, the light source on the backlight assembly is configured to emit light of different colors. An adjustable light source module is provided on the backlight assembly, and the adjustable light source module can emit light of different colors including red, green, blue, yellow, white, etc. The LED lamp array on the backlight assembly can emit light of different colors, and the light of different colors is transmitted to the photographed object and received by the imaging assembly 500, so that a color imaging picture can be obtained. When the upper cover 200 is covered on the first chamber 110 to form a darkroom state, the controller is used to send different driving instructions to the adjustable light source module at different acquisition times to drive the adjustable light source module to respectively emit light signals of matching colors; the imaging assembly 500 is used to respectively collect the intermediate images of the biological sample membrane under the light signal at each acquisition time to output the color image corresponding to the biological sample membrane. For example, at the first acquisition moment, a driving instruction for emitting blue light is sent to the adjustable light source module, and the adjustable light source module responds to the corresponding driving instruction and emits the corresponding blue light; at the second acquisition moment, a driving instruction for emitting red light is sent to the adjustable light source module, and the adjustable light source module responds to the corresponding driving instruction and emits the corresponding red light; similarly, at the third acquisition moment, a driving instruction for emitting yellow light is sent to the adjustable light source module, and the adjustable light source module responds to the corresponding driving instruction and emits the corresponding yellow light; at the fourth acquisition moment, a driving instruction for emitting green light is sent to the adjustable light source module, and the adjustable light source module responds to the corresponding driving instruction and emits the corresponding green light... and so on, and therefore, no further details are given here. The imaging component 500 is used to obtain images corresponding to the biological sample membrane under different light signals at these acquisition moments, calibrate several of these images, and fuse the calibrated images to obtain a final color image corresponding to the biological sample membrane. The images corresponding to the biological sample membrane at different acquisition moments are stored in a timely manner for subsequent aggregation processing.

[0071] Specifically, the images collected by the imaging technology used in the prior art for bonded imaging are all in black and white, but such imaging results cannot meet the higher requirements of imaging analysis. In the present application, the problem that the existing Mark imaging can only be in black and white and cannot meet the requirements of actual imaging scenarios is solved, and color imaging of biological sample membranes is achieved, which can more accurately, clearly and comprehensively reflect the characteristics and status of the biological sample membranes, facilitate better analysis, and meet higher requirements of imaging analysis.

[0072] In this embodiment, a cooling mechanism is also provided within the second chamber 120 to reduce the internal temperature of the imaging device. This cooling mechanism can be used to cool the interior of the imaging device, preventing overheating that could affect imaging stability, thereby achieving better images. The cooling mechanism can be a fan or a semiconductor cooler, and can cool components such as the control motherboard 600 and the touchscreen display 300 to prevent them from overheating.

[0073] like Figure 6 As shown, the bottom plate 105 of the second chamber 120 of the imaging device is located above the plane where the support portion 106 of the imaging device is located, and a ventilation hole 1051 is opened on the bottom plate 105 of the second chamber 120. Figure 2 、 Figure 4 As shown, two air outlets 107 are provided on the side of the housing 101 opposite the touch screen 300. Two fans are located within the second chamber 120, with the air outlet sides of the fans facing the air outlets 107. When the fans are operating, they expel the hot air emitted from the interior of the imaging device through the air outlets 107 and allow cooler air from outside to enter through the ventilation holes 1051. This ensures that the temperature inside the imaging device is maintained at a low level, thereby preventing overheating that could affect imaging stability.

[0074] Imaging assembly 500 includes an imaging assembly body 501. A fiber optic panel and / or protective film are provided in the photosensitive area above imaging assembly body 501. The fiber optic panel or protective film protects imaging assembly body 501 without affecting the imaging effect. Imaging assembly body 501 can utilize a device capable of imaging biological samples, such as a CCD (charge-coupled device) detector or a CMOS (complementary metal oxide semiconductor) detector.

[0075] In this embodiment, a fiber optic panel 502 is provided in the photosensitive area above the imaging component body 501, and a protective film (not shown in the figure) is provided above the fiber optic panel 502. Since the fiber optic panel 502 has the advantages of low light loss and total reflection, no matter how thick the fiber optic panel is, it will not affect the imaging effect of the sample film on the imaging component 500. Since the fiber optic panel 502 is quartz fiber glass, this quartz fiber glass is pressed from countless fiber optic tubes, each of which has a core and a cladding, wherein the core is quartz glass, and the cladding is to generate total reflection of the light entering the fiber optic tube to achieve light transmission. The thickness of the protective film used is between 0.01mm and 2mm, and the material of the protective film can be tempered glass film or hard plastic film.

[0076] In some other embodiments, only the optical fiber panel 502 or the protective film may be provided to protect the imaging component body 501 .

[0077] In this embodiment, the specific structure of the imaging device is as follows: Figure 4-5 As shown, the shell 100 of the imaging device includes a shell body 101, and a device middle frame 102 is provided on the upper side of the shell body 101. The device middle frame 102 has a shaft mounting portion hinged to the upper cover 200, and the upper cover 200 is hinged to the shaft mounting portion through a shaft. A shielding cover 104 is provided below the device middle frame 102, and the shielding cover 104 is snap-fitted and fixed to the device middle frame 102. An imaging component 500 is fixed inside the shielding cover 104, and the imaging component 500 includes an imaging component body 501. A fiber optic panel 502 is provided in the photosensitive area above the imaging component body 501, and a protective film is provided above the fiber optic panel 502. The middle part of the device middle frame 102 is hollow, and the lower surface of the inner periphery of the device middle frame 102 is pressed above the fiber optic panel 502. An elastic sealing ring 900 is further provided between the fiber optic panel 502 and the lower surface of the inner periphery of the device middle frame 102. By providing the elastic sealing ring 900, on the one hand, it can avoid that the fiber optic panel 502 above the imaging component body 501 and the lower surface of the inner periphery of the device middle frame 102 are not tightly sealed. On the other hand, it can reduce the influence of the micro-vibration generated by the imaging device during operation on the imaging component 500, thereby avoiding the influence of the vibration of the imaging device on the imaging stability. The upper surface of the device's middle frame 102 is also provided with a ring of seals 800. This seal 800 ensures that the darkroom space is completely sealed when the upper cover 200 is closed, thereby ensuring the imaging effect. The imaging device's housing 100, upper cover 200, shielding cover 104, etc. are made of opaque materials or are coated with an opaque coating.
