Description

Technical Field

[0001] This utility model relates to the field of gel imaging technology, and specifically to a gel imaging device. Background Technology

[0002] Gel imaging systems are used for imaging and analysis of DNA / RNA / protein gels using various staining methods (such as EB, Coomassie Brilliant Blue, silver staining, and SYBR Green) and non-chemiluminescent methods such as microplates and petri dishes. It is a gel analysis system that integrates observation, imaging, and analysis of gels. It can be applied to routine bioengineering research such as molecular weight calculation, density scanning, density quantification, and PCR quantification.

[0003] The core principle of gel imaging systems is based on the fluorescence excitation of a sample under illumination. When light from the source shines on the sample, the complexes within it undergo a fluorescence reaction, generating fluorescence signals. By imaging these fluorescence signals, image information of the biological sample can be obtained. Software analysis can then be used to obtain the sample's optical density information, thereby calculating the sample's concentration or mass. Qualitative analysis relies on the differences in migration rates of the sample on electrophoresis gels or other carriers. By comparing the positions of the unknown sample and standards in the spectrum, the composition and properties of the unknown sample can be determined.

[0004] Most existing gel imaging systems place the lens on the top of the stage, with the lens pointing downwards towards the light box. To obtain a larger field of view, the size of the gel imaging system also increases. Furthermore, a filter is placed at the lens to filter ultraviolet light to improve image quality, but the image effect on protein gel is not ideal, with low resolution and color distortion.

The driving assembly is used to drive the filter to move.

[0011] Based on the above technical solution, the present invention can be further improved as follows:

[0012] Furthermore, the refractive structure includes a housing and at least one plane mirror. The housing has an inner cavity, a light outlet, and a light inlet. The light outlet corresponds to the lens, and the light inlet corresponds to the light box. The plane mirror is inclined in the inner cavity and is used to refract light entering from the light inlet out of the light outlet.

[0013] Furthermore, the gel imaging device also includes a support, which is connected to the light outlet.

[0014] The camera is connected to the bracket, and the lens extends into the light outlet.

[0017] Furthermore, the driving component includes a lead screw, a nut, and a motor. The extension direction of the lead screw is the same as the extension direction of the slide rail. The nut is slidably engaged with the lead screw to form a lead screw and nut pair. The motor is connected to the machine body and is used to drive the lead screw to rotate. The nut is connected to the filter.

[0018] Furthermore, the filter and the driving component are respectively disposed on both sides of the slide rail along the axial direction of the lens;

[0019] The slide rail is provided with a through groove, the through groove extends in the same direction as the slide rail, and the through groove is provided to pass through the lens along the axial direction.

[0021] Furthermore, the gel imaging device also includes a stop and a mating block. The stop is connected to the body, and the mating block is connected to the filter so as to abut against the stop when the filter is in the first state.

[0022] Furthermore, the body includes a housing, a partition, and a hinged door. The partition is disposed inside the housing, and an installation cavity is formed between the upper side of the partition and the housing. A receiving groove is formed between the lower side of the partition and the body. The partition has a through hole extending vertically.

[0028] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0029] The light guide plate increases the effective illumination area of ​​the light box, while the refractive structure folds the light path to expand the camera's field of view, reducing the size of the gel imaging device. This results in a larger imaging field of view and a smaller size. When observing nucleic acid gel samples, the filter is moved to a first state, blocking the lens to filter ultraviolet light and improve the image quality captured by the camera. When observing protein gel samples, the filter is moved to a second state, exposing the lens, allowing the camera to directly capture images of the filter with high resolution and good color rendering. Thus, the filter can switch between the first and second states according to different types of samples, improving the imaging effect of the gel imaging device. Attached Figure Description

[0046] Please refer to Figure 1 and Figure 2 This utility model provides a gel imaging device, including a body 1, a light box 2, and a camera assembly 3. The body 1 has a receiving cavity 111. The light box 2 includes a housing 21, a light source, and a light-diffusing plate 22. The housing 21 is installed in the receiving cavity 111 and has an upward-facing opening. The light source is located inside the housing 21, and the light-diffusing plate 22 is installed in the opening. The camera assembly 3 is located on the upper side of the light box 2 and includes a camera 31, a refractive structure 32, and a filter 33. The camera 31 is disposed on the body 1, and the refractive structure 32 is disposed between the light box 2 and the camera 31 for guiding the light from the light box 2 into the lens 311 of the camera 31. The filter 33 is located on one side of the lens 311 and has a first state of blocking the lens 311 and a second state of moving away from the lens 311 so that the lens 311 is exposed. The driving component 34 is used to drive the filter 33 to move.

[0047] In this embodiment, the light-diffusing plate 22 increases the effective illumination area of ​​the light box 2, while the refractive structure 32 folds the light path while expanding the field of view of the camera 31, reducing the volume of the gel imaging device. Thus, the imaging field of view is expanded while maintaining a small size. When observing nucleic acid gel samples, the filter 33 is moved to a first state, where it blocks the lens 311 to filter ultraviolet light and improve the image quality captured by the camera 31. When observing protein gel samples, the filter 33 is moved to a second state, exposing the lens 311, allowing the camera 31 to directly photograph the filter 33 with high resolution and good color rendering. Thus, the filter 33 can switch between the first and second states according to different types of samples, improving the imaging effect of the gel imaging device.

[0048] In this embodiment, the uniform illumination area transmitted by the light source reaches 240mm × 240mm. Four 120mm × 120mm gel samples can be photographed simultaneously.

[0049] Specifically, in this embodiment, the light source includes multiple ultraviolet LED beads, which are installed inside the housing 21 and arranged in a matrix. Using these ultraviolet LED beads results in a long lifespan, low heat generation, no need for frequent replacements, and more uniform light emission.

[0050] Specifically, refer to Figure 1 , Figure 3 and Figure 5 In this embodiment, the refractive structure 32 includes a housing 321 and at least one plane mirror 322. The housing 321 has an inner cavity 3211, a light outlet 3212, and a light inlet 3213. The light outlet 3212 corresponds to the lens 311, and the light inlet 3213 corresponds to the light box 2. The plane mirror 322 is inclinedly disposed in the inner cavity 3211 for refracting light entering from the light inlet 3213 out through the light outlet 3212. The filter 33 is disposed close to the light outlet 3212.

[0051] In this embodiment, the camera 31 is mounted on one side of the body 1, and the light outlet 3212 corresponds to the lens 311. The light inlet 3213 faces downward and corresponds to the light box 2. The plane mirror 322 is inclinedly disposed in the inner cavity 3211. The light from the light box 2 enters the inner cavity 3211 through the light inlet 3213, reaches the plane mirror 322, and is refracted through the light outlet 3212 into the lens 311, thereby expanding the field of view without increasing the size of the body 1. The structure is simple and easy to set up.

[0052] It should be noted that this utility model does not limit the number of plane mirrors 322, which can be determined according to the required expanded field of view and the installation position of the camera 31. It also does not limit the tilt angle of the plane mirrors 322. The tilt angle of the plane mirrors 322 is specifically determined based on the orientation of the light inlet 3213 and the light outlet 3212, as well as the distance between each of the light inlet 3213 and the light outlet 3212 and the intersection point of the light rays. The intersection point is the point where the light rays extending along the through direction of the light inlet 3213 and the light rays extending along the through direction of the light outlet 3212 intersect.

[0053] Specifically, refer to Figure 2 , Figure 3 and Figure 5 In this embodiment, the gel imaging device further includes a support 41 connected to the housing 321 and corresponding to the light outlet 3212. The camera 31 is connected to the support 41 and at least partially extends into the light outlet 3212. A mating hole 3214 is provided on one side of the housing 321, located near the light outlet 3212, for the filter 33 to pass through. The filter 33 can move into the mating hole 3214 to align the body 332 with the lens 311, or move away from the mating hole 3214 to expose the lens 311. The structure is simple and easy to manufacture. The filter 33 passing through the mating hole 3214 allows for a closer arrangement of the filter 33 and the support 41, saving space.

[0054] For mounting the plane mirror 322, the housing 321 includes an inclined mounting plate 3215, which allows the plane mirror 322 to be fitted and mounted. The mounting plate 3215 is located at the fiber optic intersection, facilitating the installation and positioning of the plane mirror 322. In one embodiment, the plane mirror 322 can be directly fitted onto the side of the mounting plate 3215 facing the inner cavity 3211. (See reference...) Figure 3 and Figure 4 In this embodiment, the mounting plate 3215 is provided with a mounting hole adapted to the plane mirror 322, and the plane mirror 322 is installed in the mounting hole.

[0055] It should be noted that this utility model does not limit the placement of the filter 33. It can be placed between the lens 311 and the light exit port 3212, or between the light entrance port 3213 and the light box 2. The filter 33 can be movable to block or expose the light entrance port 3213 or the light exit port 3212. Therefore, the filter 33 can filter ultraviolet rays directed towards the lens 311, improving the image quality captured by the camera 31.

[0056] In this embodiment, refer to Figure 2 and Figure 6 The filter 33 includes a connecting plate 331 and a body 332. The connecting plate 331 is connected to the driving assembly 34, and the connecting plate 331 has a through-hole 3311. The connecting hole 3311 is adapted to the lens 311. The body 332 is adapted to the connecting hole 3311 and installed in the connecting hole 3311. The body 332 is used to filter ultraviolet light.

[0057] Furthermore, refer to Figure 5 , Figure 6 and Figure 8 In this embodiment, the gel imaging device further includes a camera protective cover 42. To mount the camera 31 onto the bracket 41, the housing 11 has a mounting through-hole on the side of the camera 31 facing away from the lens 311, allowing the camera 31 to pass through the mounting through-hole and be placed on the bracket 41, thus completing the mounting of the camera 31. The camera protective cover 42 is used to seal the mounting through-hole, preventing dust from the air from entering the mounting cavity 14 and contaminating the lens 311, thus affecting the imaging effect.

[0058] Reference Figure 1 and Figure 2 In this embodiment, the body 1 further includes a housing 11, a partition 12, and a hinged door 13. The partition 12 is disposed inside the housing 11, and an installation cavity 14 is formed between the upper side of the partition 12 and the housing 11. A receiving groove 1111 is formed between the lower side of the partition 12 and the body 1. The partition 12 is provided with a through hole 121 extending vertically. One side of the hinged door 13 is rotatably mounted to the housing 11, and the other side of the hinged door 13 can be fitted against the housing 11 to close the receiving groove 1111 or moved away from the housing 11 to open the receiving groove 1111. The camera assembly 3 is installed in the installation cavity 14. The receiving cavity 111 includes the receiving groove 1111. This allows the flap door 13 to be opened to place a gel sample into the receiving slot 1111, and then the flap door 13 to close the receiving slot 1111, thus forming the receiving cavity 111, which is equivalent to a darkroom; the ultraviolet light emitted by the light box 2 shines on the gel sample, exciting the gel sample to emit fluorescence; the darkroom environment facilitates the camera 31 to capture clear image information of the gel sample.

[0059] In this embodiment, the camera component 3 is disposed within the mounting cavity 14, and the housing 321 is connected to the partition 12. The light inlet 3213 corresponds to the through hole 121. The bracket 41 is connected to the housing 321, and the drive component 34 is connected to the bracket 41. The components are reasonably arranged and tightly connected.

[0060] Specifically, in order to drive the filter 33 to move within the mating hole 3214, refer to Figure 2 , Figure 3 and Figure 6 In this embodiment, the driving component 34 includes a slide rail 341, a slider 342, and a driving member 343. The slide rail 341 is connected to the body 1 and located on one side of the axial direction of the lens 311. The extending direction of the slide rail 341 intersects the axial direction of the lens 311. The slider 342 is slidably connected to the body 1 and connected to the filter 33. The driving member 343 drives the slider 342 to slide on the slide rail 341, thereby moving it closer to or further away from the lens 311 to switch between a first state and a second state. Thus, the structure is simple and easy to configure.

[0061] It should be noted that the extension direction of the mating hole 3214 is not limited, as long as it allows the filter 33 to pass through, either to cover or expose the lens 311. In this embodiment, the mating hole 3214 extends vertically and is located on the upper surface of the housing 321. The slide rail 341 extends vertically and is located on the upper side of the housing 321, with its lower end connected to the bracket 41, facilitating the placement of electrical components on both sides of the housing 321. This arrangement is both reasonable and compact.

[0062] More specifically, refer to Figure 4 and Figure 6In this embodiment, the driving component 343 includes a lead screw 3431, a nut 3432, and a motor 3433. The lead screw 3431 extends vertically, and the nut 3432 is slidably engaged with the lead screw 3431 to form a lead screw-nut pair. The nut 3432 is connected to the filter 33. The motor 3433 is connected to the machine body 1 and is used to drive the lead screw 3431 to rotate. The rotation of the drive shaft of the motor 3433 drives the lead screw 3431 to rotate, causing the nut 3432 to slide along the extension direction of the lead screw 3431, thereby driving the filter 33 to move and switch between a first state and a second state. The slide rail 341 limits the travel of the filter 33, allowing the filter 33 to move vertically, and also serves as a transition, reducing the load on the lead screw 3431 and the nut 3432. Furthermore, the cooperation between the lead screw 3431 and the nut 3432 makes the movement of the filter 33 more stable and allows for fine adjustment of the position of the filter 33, ensuring precise alignment between the filter 33 and the lens 311. This results in stable drive and convenient position adjustment.

[0063] In this embodiment, refer to Figure 2 , Figure 3 and Figure 6 The filter 33 and the driving member 343 are respectively disposed on both sides of the slide rail 341 along its thickness direction. The slide rail 341 has a through groove 3411 extending vertically, which runs through the thickness direction of the slide rail 341. The gel imaging device also includes a connector 344, which passes through the through groove 3411, and its two ends are respectively connected to the filter 33 and the nut 3432. This makes the connection between the driving member 343 and the slide rail 341 tighter and reduces space occupation.

[0064] In another embodiment, the drive element 343 is configured as a lifting motor, which is a linear motor; the drive element 343 may also be configured as a cylinder.

[0065] Reference Figure 4 and Figure 6 In this embodiment, the gel imaging device further includes a stop 51 and a mating part 52. The stop 51 is connected to the bracket 41 and located on one side of the slide rail 341. The mating part 52 is connected to the connecting plate 331 so as to abut against the stop 51 when the filter 33 is in the first state. Thus, the stop 51 restricts the movement of the filter 33, ensuring that the filter 33 can move accurately to the first state and improve the imaging effect.

[0066] Furthermore, in one embodiment, the stop portion 51 is provided as a stop block. When the filter 33 is moved to the first state, the stop block abuts against the mating portion 52. When the filter 33 is moved to the second state, the stop block and the mating portion 52 are spaced apart along the extending direction of the slide rail 341. Thus, the structure is simple, easy to manufacture, and low in cost.

[0067] In this embodiment, the stop portion 51 is provided with a stop groove 511, the opening of which faces upward. When it is necessary to block the lens 311, the filter 33 moves toward the lens 311, and the mating portion 52 enters the stop groove 511 and abuts against the bottom wall of the stop groove 511. When it is necessary to expose the lens 311, the mating portion 52 moves out of the stop groove 511 and is positioned away from it. Thus, the stopping groove 511 provides better limiting effect and can precisely limit the movement.

[0068] It should be noted that in this embodiment, the setting of the mating part 52 is not limited, as long as it is located within the stop groove 511 when the filter 33 is in the first state and is away from the stop groove 511 when the filter 33 is in the second state.

[0069] In this embodiment, refer to Figure 1 and Figure 2 The receiving slot 1111 is also provided with a sample tray 15, which is located on the upper side of the light box 2 and is used to place gel samples. The middle part of the sample tray 15 is hollowed out to expose the light box 2.

[0070] In addition, refer to Figure 7In this embodiment, the lens 311 is configured as a zoom lens. The gel imaging device also includes at least two LED white light lamps 61 and at least two LED ultraviolet lamps 62. The two LED white light lamps 61 are respectively installed on two opposite sidewalls of the receiving tank 1111, and the two LED ultraviolet lamps 62 are respectively installed on two opposite sidewalls of the receiving tank 1111, located above the LED white light lamps 61. The two LED white light lamps 61 are used for illumination and observation of protein gel samples. The two LED ultraviolet lamps 62 are used for observation of nucleic acid gel samples. When it is necessary to observe the gel sample, first open the flip door 13, then turn on the two LED white light lamps 61 for illumination, and then place the gel sample on the sample tray 15. If the observed substance is protein gel, turn on the light source inside the light box 2, and keep the two LED white lights 61 on and the two LED ultraviolet lights 62 off; if the observed substance is LED ultraviolet light 62, turn on the corresponding LED ultraviolet light 62 or the light source of the light box 2, and turn off the two LED white lights 61.

[0071] It should be noted that, in this embodiment, the wavelength of the ultraviolet light emitted by the light box 2 is 310nm, the wavelength of one of the LED ultraviolet lamps 62 is 254nm, and the wavelength of the other LED ultraviolet lamp 62 is 365nm.

[0072] In this embodiment, refer to Figure 2 The gel imaging device also includes a fan 7, which is disposed within the mounting cavity 14. The sidewall of the mounting cavity 14 is provided with multiple heat dissipation holes 141. The fan 7 is used to dissipate the heat generated by the camera 31, the motor 3433, and other components during operation within the mounting cavity 14.

[0073] Furthermore, in this embodiment, reference is made to Figure 2 , Figure 8 and Figure 9 The gel imaging device also includes an industrial computer 81, a control circuit board, a power switch, a power socket, a network cable interface, and a USB external interface. The mounting cavity 14 has a mounting window 142, which faces the same direction as the opening of the receiving slot 1111. The industrial computer 81 is mounted on the mounting window 142 for human-computer interaction and image acquisition. The control circuit board and the power switch are both located within the mounting cavity 14 and are electrically connected to the industrial computer 81. The power socket, the network cable interface, and the camera protective cover 42 are all located on one side of the housing 11. The power socket is used for electrical connection to an external power source.

[0074] In this embodiment, the gel imaging device further includes a magnetic component and a magnetic suction component. One of the magnetic component and the magnetic suction component is located on the other side of the flip door 13, and the other is located at the position where the housing 11 fits against the flip door 13. Thus, when the flip door 13 closes the receiving slot 1111, the magnetic component and the magnetic suction component attract each other, ensuring that the flip door 13 is tightly closed.

[0075] In this embodiment, the magnetic component is a magnetic steel ball, which is located on the other side of the flip door 13. The housing 11 is made of a magnetic material, so that the flip door 13 can fit tightly against the housing 11.

[0076] Reference Figure 2 and Figure 9 In this embodiment, the gel imaging device further includes a limit switch 82, which is located at the opening of the receiving groove 1111. When the flip door 13 is closed, the flip door 13 is in contact with the limit switch 82; when the flip door 13 is open, the flip door 13 moves away from the limit switch 82, thereby enabling the limit switch 82 to detect whether the flip door 13 is open during the imaging experiment, ensuring the accuracy of the experimental results.

[0077] Reference Figure 1 and Figure 2 In this embodiment, the gel imaging device further includes a movable frame 16, which is movably connected to the housing 11 along the depth direction of the receiving groove 1111, and is used to place the light box 2. The gel imaging device also includes a protective plate 9, the lower side of which is rotatably connected to the side of the movable frame 16 near the flip door 13, so that the upper side of the protective plate 9 can be flipped up and down. This allows the movable frame 16 to be pulled out from the receiving groove 1111 for easy gel cutting; and the protective plate 9 is raised to protect the eyes from ultraviolet light damage during gel cutting.

[0078] It should be noted that, referring to Figure 1 and Figure 7 In this embodiment, each of the two opposite sidewalls of the receiving groove 1111 is provided with a guide rail 17. The two guide rails 17 are arranged opposite each other and extend along the depth direction of the receiving groove 1111. Two sliding rails 18 are provided on each side of the movable frame 16, and the two sliding rails 18 are slidably connected to the two guide rails 17 respectively. To increase the travel of the movable frame 16, four slide rails 341 are provided; each slide rail 18 is slidably connected to the corresponding two slide rails 341 in sequence.

[0079] Reference Figure 1 and Figure 8In this embodiment, the housing 11 includes an annular protrusion 19, which surrounds the opening of the receiving groove 1111. The flip door 13 has a groove 131 corresponding to the annular protrusion 19, and annular adhesive strips 132 are attached to the two opposite sidewalls of the groove 131. When the flip door 13 is closed, the annular protrusion 19 enters the groove 131, and the two opposite sides of the annular protrusion 19 are respectively attached to the two annular adhesive strips 132. This achieves a good light-blocking effect and improves the imaging effect.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
