Description

Technical Field

[0001] This utility model relates to the field of chemiluminescence detection technology, specifically to a dual-camera chemiluminescence imaging instrument. Background Technology

[0002] Chemiluminescence imaging, as a highly sensitive detection method, is widely used in biomedicine, molecular diagnostics, and drug development, playing a particularly important role in experiments such as protein blotting and nucleic acid detection. The core principle of chemiluminescence imaging is to detect the light signals released by a sample during a chemical reaction, thereby enabling qualitative and quantitative analysis of the target substance.

[0003] Currently, most chemiluminescence imaging instruments are equipped with only a single monochrome camera. While monochrome cameras offer advantages such as high sensitivity and low noise in low-light environments, they can only capture grayscale images and cannot acquire color information of the sample (such as multicolor fluorescent labels and color changes after chromogenic substrate reactions). This necessitates the use of a separate color imaging device during experiments, increasing operational complexity and time costs. Furthermore, frequent device switching can lead to sample position shifts or light signal attenuation, affecting the precise alignment of grayscale and color images and reducing the reliability of analytical results. Utility Model Content

[0004] Based on the above description, this utility model provides a dual-camera chemiluminescence imaging instrument, which aims to solve the problem that existing chemiluminescence imaging instruments equipped with a single black and white camera cannot acquire color information of samples.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A dual-camera chemiluminescence imaging instrument, comprising:

[0007] A housing assembly includes a housing having a receiving cavity and a dark cavity, the receiving cavity communicating with the dark cavity through at least one lens hole;

[0008] At least one camera is disposed within the receiving cavity and corresponds one-to-one with the at least one lens hole, the lens of the at least one camera facing the lens hole;

[0009] A sample carrier assembly is disposed within the dark cavity. The sample carrier assembly includes a tray and an illumination element. The illumination element is configured as at least one pair, with each pair of illumination elements symmetrically arranged about the center line of the tray. The illumination element includes a light source.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the housing assembly includes a hinged door connected to the housing, the hinged door corresponding to the dark cavity.

[0012] Furthermore, an opening / closing detection element is provided inside the dark cavity.

[0013] Furthermore, a sealing strip is provided between the housing and the hinged door.

[0014] Furthermore, the housing assembly includes a display screen disposed on the housing, the display screen corresponding to the receiving cavity.

[0015] Furthermore, the lighting element includes a mounting plate, which is mounted on the side wall of the dark cavity, and the light source is mounted on the mounting plate.

[0016] Furthermore, it includes a cooling fan disposed within the receiving cavity, and the housing has multiple heat dissipation holes corresponding to the cooling fan, with the air inlet end of the cooling fan facing the multiple heat dissipation holes.

[0017] Furthermore, it includes a temperature sensor disposed within the receiving cavity.

[0018] Furthermore, it includes a control switch, which is disposed on the housing.

[0019] Furthermore, it includes a power socket, which is located on the housing.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0021] (1) This application overcomes the limitations of a single imaging mode by combining a black-and-white camera and a color camera. While improving the sensitivity of chemiluminescence detection, it also achieves efficient acquisition of multi-dimensional data, enabling accurate analysis of complex biological samples. Furthermore, the black-and-white camera and the color camera are integrated into the same cavity, allowing the two cameras to share the same field of view and avoiding image misalignment caused by sample movement.

[0022] (2) This application effectively isolates external light interference through the separation design of the dark cavity and the receiving cavity, ensuring high sensitivity detection of chemiluminescence signals. In addition, the symmetrical light source layout improves the uniformity of illumination and avoids imaging distortion caused by light intensity differences.

[0023] (3) This application uses an opening and closing detection device to detect whether the flip door is fully closed. When the flip door is not fully closed, the camera can be paused to ensure that the dark cavity is always in a sealed state, prevent light pollution caused by misoperation, and improve the reliability of the results.

[0045] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a dual-camera chemiluminescence imaging instrument, including a housing assembly 10, an imaging assembly 20, and a sample carrier assembly 30. The housing assembly 10 includes a housing 11, which has a cavity 111. The imaging assembly 20 is disposed within the cavity 111 and includes at least one imaging unit. The imaging unit includes two cameras 21, which are a monochrome camera 21 and a color camera 21, respectively. The sample carrier assembly 30 is disposed within the cavity 111 and is arranged opposite to the lens of the monochrome camera 21 and the lens of the color camera 21.

[0046] In this embodiment, taking advantage of the weak chemiluminescence signal and low background noise, the monochrome camera 21 prioritizes capturing grayscale images to ensure high-sensitivity detection of weak light signals. The color camera 21 simultaneously or sequentially captures color images of the sample under the same experimental conditions, recording color characteristics. This collaboration between the monochrome and color cameras 21 overcomes the limitations of a single imaging mode, improving the sensitivity of chemiluminescence detection while achieving efficient acquisition of multi-dimensional data for accurate analysis of complex biological samples. Furthermore, the monochrome and color cameras 21 are integrated into the same cavity 111, allowing both cameras to share the same field of view and avoiding image misalignment caused by sample movement.

[0047] Reference Figures 1 to 2 As shown, in some embodiments, the cavity 111 is divided into a receiving cavity 1111 and a dark cavity 1112 by a partition 112, at least one imaging unit is disposed in the receiving cavity 1111, and the partition 112 has a lens hole corresponding to each camera 21.

[0048] In this embodiment, the dark cavity 1112 provides a light-proof environment for the sample, and the camera 21 inside the receiving cavity 1111 captures the chemiluminescence signal of the sample in the dark cavity 1112 through the lens aperture. The separation design between the dark cavity 1112 and the receiving cavity 1111 effectively isolates external light interference, ensuring high-sensitivity detection of the chemiluminescence signal.

[0049] For example, the light source 321 can be an LED white light or the like. The center line of the tray 31 is formed by connecting the midpoints of the two long sides of the tray 31.

[0050] Reference Figure 1 and Figure 3 As shown, in some embodiments, the housing assembly 10 includes a hinged door 12 connected to the housing 11, and the hinged door 12 corresponds to the dark cavity 1112.

[0051] For example, the hinged door 12 is rotatably connected to the housing 11.

[0052] In this embodiment, the closed flap 12 can maintain the airtightness of the dark cavity 1112, thereby preventing light leakage from affecting imaging.

[0053] In some embodiments, the dark cavity 1112 is provided with an opening and closing detection element 121.

[0054] For example, the opening / closing detection element 121 can be a distance sensor or a limit switch, etc.

[0055] In this embodiment, the operation of camera 21 can be paused when the flip door 12 is not fully closed, ensuring that the dark cavity 1112 is always in a sealed state, preventing light pollution caused by misoperation, and improving the reliability of the results.

[0056] Reference Figure 1 As shown, in some embodiments, a sealing strip 122 is provided between the housing 11 and the hinged door 12.

[0057] For example, the sealing strip 122 can be made of an elastic material, such as silicone.

[0058] In this embodiment, the sealing strip 122 forms a physical barrier between the flip door 12 and the housing 11, enhancing the sealing performance of the dark cavity 1112 and completely blocking external light.

[0059] Reference Figure 1 As shown, in some embodiments, the housing assembly 10 includes a display screen 13 disposed on the housing 11, the display screen 13 corresponding to the receiving cavity 1111.

[0060] For example, the display screen 13 can be a touch display screen 13 or a non-touch display screen 13, etc.

[0061] In this embodiment, the display screen 13 can display imaging data, device parameters, and the operation interface in real time. This provides an intuitive operating status interface, making it easier for users to monitor the experimental process and quickly adjust settings, thus improving operational convenience.

[0062] Reference Figures 1 to 2 and Figure 4 As shown, in some embodiments, the imaging assembly 20 includes a housing 22 disposed on a partition 112. The housing 22 has a mounting cavity 221 corresponding to each lens hole, and the camera 21 is disposed in the mounting cavity 221 in a corresponding manner, with the lens of the camera 21 facing the lens hole.

[0063] In this embodiment, the black-and-white camera 21 and the color camera 21 are fixed to the partition 112 by the housing 22. The partition 112 serves as a support structure to ensure the relative positional accuracy between the housing 22 and the dark cavity 1112, and to prevent the camera 21 from shifting due to mechanical vibration.

[0064] Reference Figure 1 and Figure 4 As shown, in some embodiments, the imaging assembly 20 includes a spacer 23 disposed between the housing 22 and the partition 112, and the spacer 23 corresponds to the monochrome camera 21.

[0065] For example, the gasket 23 may be made of an elastic material, such as silicone or foam.

[0066] In this embodiment, the gasket 23 absorbs the mechanical vibration transmitted by the partition 112 through deformation, thereby protecting the black and white camera 21 during transportation.

[0067] Reference Figures 1 to 2 and Figure 5As shown, in some embodiments, the sample carrier assembly 30 includes a tray 31 and an illumination element 32, the illumination element 32 being configured as at least a pair, each pair of illumination elements 32 being symmetrically arranged about the center line of the tray 31, and the illumination element 32 including a light source 321.

[0068] In this embodiment, each pair of illumination elements 32 is symmetrically distributed around the center line of the tray 31, and the light source 321 illuminates the sample uniformly, reducing imaging shadows. The symmetrical layout of the light source 321 improves illumination uniformity and avoids imaging distortion caused by differences in light intensity.

[0069] Reference Figure 2 and Figure 5 As shown, in some embodiments, the lighting element 32 includes a mounting plate 322, which is mounted on the side wall of the dark cavity 1112, and the light source 321 is mounted on the mounting plate 322.

[0070] For example, the mounting plate 322 can be connected to the side wall of the dark cavity 1112 by screws or the like, or the mounting plate 322 can be engaged with the side wall of the dark cavity 1112.

[0071] In this embodiment, the light source 321 is fixed to the side wall of the dark cavity 1112 by the mounting plate 322 to ensure that the illumination angle is fixed and to avoid optical path deviation caused by the offset of the light source 321.

[0072] Reference Figure 1 and Figure 3 As shown, in some embodiments, the dual-camera chemiluminescence imaging instrument includes a cooling fan 40, which is disposed in the receiving cavity 1111. The housing 11 has a plurality of heat dissipation holes 113 corresponding to the cooling fan 40, and the air inlet end of the cooling fan 40 faces the plurality of heat dissipation holes 113.

[0073] In this embodiment, the cooling fan 40 can reduce the operating temperature of the camera 21 and electronic components, preventing performance degradation or damage to electronic components due to overheating.

[0074] Reference Figures 1 to 2 As shown, in some embodiments, the dual-camera chemiluminescence imaging instrument includes a temperature sensor 50, which is disposed within the receiving cavity 1111.

[0075] For example, temperature sensor 50 can be a thermocouple or a semiconductor sensor, etc.

[0076] In this embodiment, the cooling fan 40 is linked to the temperature sensor 50. When the temperature of the housing 1111 exceeds a threshold, the cooling fan 40 can be activated to dissipate heat. This not only enables precise temperature control to ensure that the camera 21 operates in a suitable environment, reducing the interference of thermal noise on image quality and improving data accuracy, but also reduces energy consumption.

[0077] Reference Figure 3As shown, in some embodiments, the dual-camera chemiluminescence imaging instrument includes a control switch 60, which is disposed on the housing 11.

[0078] For example, the control switch 60 can be a physical button or a touch switch, etc.
