Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, and in particular to an image acquisition device and an analysis device. Background Technology

[0002] Existing blood typing analyzers typically use image acquisition devices such as CCD cameras or video cameras to acquire image data for analysis. Taking a plate-type blood typing analyzer as an example, the image acquisition device acquires images of the experimental results in each microplate well, and the computer analyzes the pixel data acquired by the imaging device to determine the blood typing result.

[0003] Because the microplate requires a large imaging area, a longer aberration-correcting lens is needed to make the microplate image clear. This increases the working distance of the image acquisition device, which means that the distance between the lens and the material is longer, resulting in a larger structure for the blood typing analyzer. Utility Model Content

[0004] To address the issue of the increased structural size of blood typing analyzers due to the extended working distance of image acquisition devices, the purpose of this invention is to propose an image acquisition device and an analysis device.

[0005] To achieve the above objectives, the image acquisition device proposed in this utility model includes:

[0006] The housing module has a first cavity inside;

[0007] A first driving module, an image capture module, and a transparent carrier are installed in the first cavity. The carrier has a receiving surface for placing materials. The image capture module is located below the receiving surface. The first driving module can drive the image capture module to move relative to the material along a first direction. When the image capture module moves relative to the material along the first direction, it can gradually acquire image information of the material located on the receiving surface.

[0008] In one embodiment, the image acquisition device further includes a positioning structure capable of fixing the material to the receiving surface.

[0009] In one embodiment, the positioning structure includes a limiting part, a first pushing part, and a driving part;

[0010] When the material is placed on the receiving surface, it can be located between the limiting part and the first pushing part. The driving part can drive the first pushing part so that the first pushing part and the limiting part press against the material to fix the material on the receiving surface.

[0011] In one embodiment, the limiting part is configured as the cavity wall of a second cavity, and the second cavity is connected to the first cavity;

[0012] And / or, the limiting part is provided with a first limiting surface and a second limiting surface set at a preset angle, and the first limiting surface and the second limiting surface can abut against the material.

[0013] In one embodiment, the housing module includes a first housing portion and a second housing portion. The first housing portion forms the first cavity and has an opening communicating with the first cavity. The second housing portion is slidable relative to the first housing portion and has an open position and a closed position relative to the first housing portion. In the open position, the material can enter and exit the first cavity through the opening. In the closed position, the second housing portion can block the opening.

[0014] In one embodiment, the image acquisition device further includes a second driving module, which is capable of driving the second housing to reciprocate between the open position and the closed position;

[0015] And / or, the housing module is provided with a brightness enhancement module, which is used to enhance the brightness in the first cavity.

[0016] In one embodiment, a brightness enhancement module is provided inside the housing module;

[0017] The brightness enhancement module includes a first brightness enhancement part and a second brightness enhancement part. The first brightness enhancement part is located below the carrier, and the second brightness enhancement part is located above the carrier, or the second brightness enhancement part is located on the periphery of the carrier.

[0018] In one embodiment, the first brightness enhancement part is configured as a first light-emitting element disposed on the image capture module, and the first light-emitting element is movable along with the image capture module.

[0019] And / or, the second brightness enhancement part is configured as a reflector or a second light-emitting element.

[0020] In one embodiment, the image acquisition device further includes a transmission assembly, and the first pushing part is installed on the transmission assembly. The first pushing part has a pressing position and a releasing position. In the pressing position, the first pushing part can press against the material, and in the releasing position, the first pushing part is spaced apart from the material.

[0021] When the second housing is in the open position, the transmission assembly drives the first pushing part to the release position;

[0022] When the second housing moves from the open position to the closed position, the transmission assembly causes the first abutting part to move from the release position to the abutting position.

[0023] In one embodiment, the drive unit is configured as an elastic element, and the transmission assembly is connected to the elastic element;

[0024] When the second shell is in the open position, the second shell drives the first pushing part to the release position through the transmission assembly, and at the same time the elastic element undergoes elastic deformation;

[0025] When the second housing moves from the open position to the closed position, the elastic element gradually recovers and drives the transmission assembly, so that the transmission assembly drives the first abutting part from the release position to the abutting position.

[0026] In one embodiment, the transmission assembly includes a transmission plate slidably disposed on the first housing portion and a protrusion protruding from the transmission plate;

[0027] The second shell portion is provided with a second abutting portion. When the second shell portion moves from the closed position to the open position, the second abutting portion can abut against the protrusion so that the first abutting portion is in the released position.

[0028] In one embodiment, the transmission assembly further includes a guide rail disposed on the transmission plate, the first pushing part is configured as a rocker arm, one end of the rocker arm is rotatably connected to the first housing part, the other end is rotatably connected to the guide rail, and is capable of sliding along the guide rail;

[0029] In one embodiment, the image acquisition device further includes a third driving module, wherein the carrier is movably disposed in the first cavity, and the third driving module is capable of driving the carrier and the material disposed on the carrier to move;

[0030] Alternatively, the image capture module is configured as a scanning head, the first direction is a straight line, and the first driving module can drive the scanning head to reciprocate along the first direction.

[0031] This utility model also proposes an analysis device, including an analysis and processing module and an image acquisition device as described above, wherein the image acquisition device is electrically connected to the analysis and processing module.

[0032] The technical solution of this utility model adopts a method of continuously moving the image capture module to acquire complete image information of the material, thereby shortening the distance between the image capture module and the material, and thus shortening the working distance of the image capture module. When the image capture module is in one position, it cannot acquire complete image information of the material. This reduces the object distance between the image capture module and the material, that is, shortens the distance between the image capture module and the receiving surface, thereby reducing the height of the image acquisition device and making the structure of the image acquisition device more compact. This solves the problem in the prior art that the blood type analyzer has a large structure due to the increased working distance of the image acquisition device. Attached Figure Description

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0061] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0063] This utility model proposes an image acquisition device 100, which is applied to an analysis device 300, wherein the analysis device 300 can be a blood typing analyzer. However, the image acquisition device 100 of this application can also be applied to other analysis devices 300 that need to acquire image information of target objects.

[0064] Please see Figures 1 to 3In one embodiment of this utility model, the image acquisition device 100 includes a housing module 200, wherein the housing module 200 has a first cavity 230 inside; a first driving module (not shown), an image capture module 400, and a transparent carrier 500 installed in the first cavity 230, wherein the transparent carrier 500 can be made of glass, plastic, etc., and the specific material is not limited in this application; further, the carrier 500 has a receiving surface 510, which is used for placing material 1000. It can be understood that the material 1000 is placed on the receiving surface 510 of the carrier 500; wherein the image capture module 400 is located below the receiving surface 510, and the first driving module can drive the image capture module 400 to move relative to the material 1000 in a first direction. When the image capture module 400 moves relative to the material 1000 in the first direction, it can gradually acquire image information of the material 1000 located on the receiving surface 510. Furthermore, in some scenarios, the image information of the material 1000 refers to the image information of the experimental results when the material is used as a carrier in an experiment. It is understood that initially, when the image capture module 400 moves relative to the material 1000 along the first direction, it cannot fully acquire the image information of the material 1000; it can only acquire a portion of the image information. As the image capture module 400 gradually moves relative to the material 1000 along the first direction, the acquired image information of the material 1000 becomes more comprehensive. When the image capture module 400 moves to a designated position, the distance traveled is sufficient to acquire all the image information of the material 1000. Furthermore, in this embodiment, gradually acquiring the image information of the material 1000 in this way, compared to acquiring the image information of the material 1000 at once using a CCD camera or video camera in the prior art, can shorten the distance between the image capture module 400 and the carrier surface. It is understandable that, since the image capture module 400 acquires all image information of the material 1000 by continuously moving, when the image capture module 400 is in one position, it is not necessary to acquire all image information of the material 1000. As the image capture module 400 moves relative to the material 1000 along the first direction to the designated position, all image information is acquired. This reduces the object distance between the image capture module 400 and the material 1000, that is, shortens the distance between the image capture module 400 and the receiving surface 510, thereby reducing the height of the image acquisition device 100 and making the structure of the image acquisition device 100 more compact. This solves the problem in the prior art where the blood type analyzer has a larger structure due to the increased working distance of the image acquisition device 100.It should be noted that for a CCD camera or camcorder to acquire all image information of material 1000 in a single shot by taking photos, the object distance between the CCD camera or camcorder and material 1000 needs to be increased to ensure that the CCD camera or camcorder can acquire all image information of material 1000 in one shot. It should also be noted that the aforementioned comparison is based on material 1000 of the same specifications.

[0065] It should be noted that when the image acquisition device 100 in this embodiment is applied to the analysis device 300, especially a blood typing analyzer, all image information of the material 1000 obtained by the image acquisition device 100 is fed back to the analysis module in the blood typing analyzer. The analysis module analyzes the all image information and determines the blood typing result. It is understandable that because the image acquisition device 100 has a compact and small structure, this facilitates the miniaturization design of the blood typing analyzer.

[0066] Furthermore, in some embodiments, reference is made to... Figure 3 The image capture module 400 is configured as a scanning head, wherein the first direction is a linear direction. The first driving module can drive the scanning head to reciprocate along the first direction. Further, the first driving module can be a motor guide rail slider structure, or other structures capable of driving the scanning head to reciprocate along the first direction. It can be understood that when the scanning head moves relative to the material 1000 along the first direction, the scanning head can gradually acquire image information of the material 1000 located on the receiving surface 510. After moving to a designated position, the scanning head can acquire all image information of the material 1000. It should be noted that, under this structure, the object distance between the scanning head and the material 1000 can be relatively short, thereby making the structure of the image acquisition device 100 compact and small. When the image capture module 400 is configured as a scanning head, the scanning head is set inside the scanning head housing 410, wherein the scanning head can be set in the first cavity 230, and the carrier 500 is installed in the scanning head housing 410.

[0067] However, this design is not limited to this. In some embodiments, the image capture module 400 can also be configured as a camera, wherein the first drive module can drive the camera to reciprocate along a first direction. During the movement of the camera in the first direction, it can gradually acquire image information of the material 1000 located on the receiving surface 510. It should be noted that when a camera is used, the camera lens can be a macro lens. The macro lens can reduce the object distance between the camera and the material 1000, thereby shortening the distance between the camera and the material 1000 and solving the problem caused by the large distance between the camera and the material in the prior art. The first drive module can adopt a motor guide rail slider structure.

[0068] It should be noted that in some embodiments, depending on the trajectory of the image capture module 400, the first direction may also be a non-linear direction, such as a planar spiral trajectory or an arc trajectory.

[0069] In one embodiment, reference Figure 4 , Figure 5 , Figure 6 , Figure 7 The image acquisition device 100 also includes a positioning structure 600, which can fix the material 1000 to the receiving surface 510. Understandably, the positioning structure 600 can constrain the material 1000, minimizing any loosening or shaking of the material 1000 when the image capture module 400 moves relative to it. It should be noted that loosening or shaking of the material 1000 will cause blurry image information. Therefore, the positioning structure 600 can minimize blurry image information and improve image acquisition quality. When applied to a blood typing analyzer, high-quality image information, compared to low-quality image information, allows for faster analysis results and improved accuracy. In some embodiments, when the image acquisition device 100 is not equipped with the positioning structure 600, and in order to prevent the material 1000 from shaking, a rubber ring can be provided at the bottom of the material 1000 to increase the friction between the bottom of the material 1000 and the receiving surface 510.

[0070] In some embodiments (not shown), the positioning structure 600 can be configured as a clamping structure (not shown) mounted on the housing module 200, wherein the clamping structure includes two opposing grippers. After the material 1000 is placed on the receiving surface 510, it can be positioned between the two opposing grippers. At this time, the two grippers move closer to each other to clamp the material 1000, thereby fixing the material 1000 to the receiving surface 510. However, this design is not limited to this. In some embodiments, the positioning structure 600 can also be other structures.

[0071] In one embodiment, reference Figure 2 , Figure 8The positioning structure 600 includes a limiting part, a first pushing part 620, and a driving part 630. In some embodiments, the limiting part can be configured as a second cavity 610, which is connected to the first cavity 230. In some embodiments, the structure of the first cavity 230 and the cavity shape and distribution of the second cavity 610 are different. For example, the second cavity 610 is located above the first cavity 230. In this case, the first cavity 230 and the second cavity 610 can form a stepped cavity structure. In some embodiments, the cavity shapes of the first cavity 230 and the second cavity 610 can be the same, but the distribution of the second cavity 610 and the first cavity 230 is different. For example, the second cavity 610 is located above the first cavity 230. In this case, the first cavity 230 and the second cavity 610 can be regarded as a single cavity structure. That is, the first cavity 230 and the second cavity 610 can be regarded as two connected parts of a single cavity structure.

[0072] Furthermore, when the material 1000 is placed on the receiving surface 510, it can be located within the second cavity 610. The driving unit 630 can drive the first pushing part 620, which pushes the material 1000 placed in the second cavity 610, so that the material 1000 is pressed against the cavity wall of the second cavity 610. It can be understood that the positioning of the material 1000 is restricted by the first pushing part 620 and the cavity wall of the second cavity 610 to fix the material 1000 on the receiving surface 510. Furthermore, in some embodiments, the driving unit 630 can be a reciprocating drive structure such as an electric telescopic rod or a cylinder assembly, and the first pushing part 620 can be configured as a pushing plate.

[0073] Furthermore, in some embodiments, the limiting part can also be configured as a limiting plate (not shown). When the material is placed on the receiving surface 510, the material can be located between the limiting plate and the first pushing part 620. The first pushing part 620 pushes the material 1000 placed on the receiving surface 510 so that the material 1000 presses against the limiting plate. The specific structure of the first pushing part 620 can be referred to the above structure.

[0074] Furthermore, in some embodiments, the limiting part is provided with a first limiting surface and a second limiting surface set at a preset angle, the first limiting surface and the second limiting surface being able to abut against the material. It should be noted that when the limiting part is constructed as the cavity wall of the second cavity 610, the first limiting surface and the second limiting surface are both cavity walls of the second cavity 610, namely the first cavity wall 611 and the second cavity wall 612 (see...). Figure 8In some embodiments, when the limiting part is configured as a limiting plate, the limiting plate can be configured as an L-shaped structure, with the first limiting surface and the second limiting surface disposed on the L-shaped limiting plate. It is understood that the first limiting surface and the second limiting surface, which are set at a preset angle, mainly restrict the movement of the material in two directions, wherein the preset angle can be ninety degrees.

[0075] In one embodiment, reference Figure 1 , Figure 2 , Figure 5 The housing module 200 includes a first housing portion 210 and a second housing portion 220. The first housing portion 210 forms a first cavity 230 and has an opening communicating with the first cavity 230. The second housing portion 220 can slide relative to the first housing portion 210 and has an open position and a closed position relative to the first housing portion 210. In the open position, the material 1000 can enter and exit the first cavity 230 through the opening. In the closed position, the second housing portion 220 can block the opening. It can be understood that before the material 1000 enters and exits the housing module 200 through the opening, the second housing portion 220 is in the open position. At this time, the material 1000 can enter the first cavity 230 and be located on the receiving surface 510, between the first pushing part and the limiting part. After entering, the second housing portion 220 is in the closed position, and the second housing portion 220 blocks the opening.

[0076] However, this design is not limited to this. In some embodiments, a second cavity 610 is constructed within the first shell portion 210, wherein the second cavity 610 is exposed within the first shell portion 210. It is understood that the opening in the first shell portion 210 is configured as the opening of the second cavity 610, and the cavity wall of the second cavity 610 is configured as a limiting portion. Material enters and exits the second cavity 610 through the opening and is located on the receiving surface 510. At this time, the first pushing portion can cooperate with the cavity wall of the second cavity 610 to fix the material 1000 on the receiving surface. Furthermore, the second shell portion 220 can cover or open the opening of the second cavity 610.

[0077] Furthermore, in some embodiments, the image acquisition device 100 further includes a second driving module (not shown), which can drive the second housing 220 to reciprocate between the open position and the closed position. Regarding the sliding of the second housing 220 relative to the first housing 210, in some embodiments, this can be understood as the second housing 220 being slidably mounted on the first housing 210. In this case, the first housing 210 is provided with a second guide rail 250, and the second housing 220 is provided with a slider that cooperates with the second guide rail 250. The second guide rail 250 can be integrally formed with the first housing 210 or fixed to the first housing 210 in other ways. The second housing 220 is mounted on the second driving module, and the second driving module drives the second housing 220 to slide relative to the first housing 210. Further, depending on the sliding trajectory of the second housing 220, the second driving module can be a linear driving module (guide rail slider motor assembly) or a rotary driving module (rotary motor assembly).

[0078] It is understandable that when the second shell 220 is in the closed position, it blocks the second cavity 610, resulting in poor lighting inside the shell module 200. To avoid this problem, in some embodiments, a brightness enhancement module 800 is provided inside the shell module 200. The brightness enhancement module 800 is used to enhance the brightness inside the first cavity 230. It should be noted that the first cavity 230 and the second cavity 610 are connected, and the brightness enhancement module 800 can enhance the brightness inside the first cavity 230 and also the brightness inside the second cavity 610. It should also be noted that in some embodiments, the shell module 200 can be made of an opaque material. This reduces the amount of ambient light entering the shell module 200 when acquiring image information of the material 1000. Ambient light has a certain degree of non-uniformity, which can affect the quality of the acquired image information. The brightness enhancement module compensates for this light. The brightness enhancement module 800 can use LED beads or other light-emitting structures.

[0079] However, this design is not limited to this. In some embodiments, the housing module 200 can be configured as a transparent material, in which case the brightness enhancement module 800 can be disposed on the outside of the housing module 200. Furthermore, in order to reduce interference from ambient light, a non-transparent housing structure can be fitted over the transparent housing module 200, in which case the brightness enhancement module 800 is disposed between the transparent housing module and the non-transparent housing structure.

[0080] In one embodiment, reference Figure 4The brightness enhancement module 800 includes a first brightness enhancement part 810 and a second brightness enhancement part 820. The first brightness enhancement part 810 is disposed below the carrier 500, and can be installed on the cavity wall of the first cavity 230. The first brightness enhancement part 810 can be configured as a first light-emitting element, and the first reflector can be an LED lamp bead. The second brightness enhancement part 820 is disposed above the carrier 500, and can be disposed on the cavity wall of the second cavity 610 or on the side of the second shell 220 facing the carrier 500. In some embodiments, the second brightness enhancement part 820 is configured as a reflector or a second light-emitting element. It should be noted that in this embodiment, by setting the first brightness enhancement part 810 and the second brightness enhancement part 820 respectively below and above the carrier 500, the brightness at the carrier 500 can be made more sufficient.

[0081] In one embodiment, the first brightness enhancement unit 810 is configured as a first light-emitting element disposed on the image capture module 400. The first light-emitting element can move along with the image capture module 400. It can be understood that when the image capture module 400 moves, the first light-emitting element can move synchronously. This can achieve the purpose of synchronous movement of the light, ensuring that the captured area is always under uniform lighting conditions and improving the quality of the acquired image information.

[0082] In one embodiment, the image acquisition device 100 further includes a transmission assembly 900. The first pushing part 620 is mounted on the transmission assembly 900. The first pushing part 620 has a pressing position and a releasing position. In the pressing position, the first pushing part can press against the material 1000. In the releasing position, the first pushing part is spaced apart from the material 1000. It can be understood that when the first pushing part is spaced apart from the material 1000, the first pushing part no longer presses against the material 1000, and the material 1000 can enter and exit the housing module 200. When the second housing part 220 is in the open position, the transmission assembly 900 drives the first pushing part 620 to the releasing position. When the second housing part 220 moves from the open position to the closed position, the transmission assembly 900 drives the first pushing part 620 from the releasing position to the pressing position. Furthermore, in some embodiments, the image acquisition device 100 further includes a position sensor, wherein the transmission component can be configured as the telescopic end of an electric telescopic rod, and the first pushing part 620 can be disposed at the telescopic end of the electric telescopic rod. In this case, the position sensor is electrically connected to the electric telescopic rod. Further, two position sensors are configured, namely a first position sensor and a second position sensor. The first position sensor is set to the open position of the second housing, and the second position sensor is set to the closed position of the second housing. When the second housing is in the open position, the first position sensor feeds a signal to the electric telescopic rod. After receiving the feedback signal, the electric telescopic rod drives the first pushing part 620 to move a preset distance to the release position, and the electric telescopic rod stops moving after moving the preset distance. When the second housing is in the closed position, the second position sensor feeds a signal to the electric telescopic rod. After receiving the feedback signal, the electric telescopic rod drives the first pushing part 620 to move a preset distance to the pressing position, and the electric telescopic rod stops moving after moving the preset distance. Of course, to prevent the material 1000 from being damaged due to excessive clamping by the first pushing part 620, an elastic buffer can be provided between the telescopic end of the electric telescopic rod and the first pushing part 620. It should be noted that this embodiment only uses an electric telescopic rod as an example. In some embodiments, other drive structures can also be used, such as cylinder assemblies, motor guide rail slider assemblies, etc.

[0083] Furthermore, in some embodiments, reference is made to... Figures 5 to 10The driving part 630 is configured as an elastic element, and the transmission assembly 900 is connected to the elastic element. When the second housing part 220 is in the open position, the second housing part 220 drives the first pushing part 620 to the release position through the transmission assembly 900, and at the same time, the elastic element undergoes elastic deformation. The second housing part 220 can be connected to the transmission assembly 900 or not. When the second housing part 220 moves from the open position to the closed position, the elastic element gradually recovers and drives the transmission assembly 900, so that the transmission assembly 900 drives the first pushing part 620 from the release position to the abutting position.

[0084] Furthermore, in some embodiments, reference is made to... Figures 5 to 10 The elastic element is configured as a tension spring, wherein one end of the tension spring is fixed to the first housing portion 210, and the other end is connected to the transmission assembly 900. In some embodiments (see reference) Figure 11 The transmission assembly 900 includes a hinged double-link structure, comprising a first link 940 and a second link 950. One end of the first link 940 is hinged to one end of the second link 950. The first link 940 is slidably disposed on the first housing portion 210. A first abutting portion 620 is disposed on the first link 940 and can be configured as the end of the first link 940 away from the hinge. The end of the second link 950 away from the hinge is rotatably connected to the second housing portion 210. 20. At this time, the transmission assembly 900 is connected to the second housing 220, and the tension spring is connected to the first connecting rod 940. When the second housing 220 moves from the closed position to the open position, the second housing 220 pulls the second connecting rod 950, which in turn pulls the first connecting rod 940, causing the first connecting rod 940 to move. During the movement, the first connecting rod 940 causes the tension spring to deform, causing the first abutting part 620 to move away from the material 1000, creating a certain gap between them. Conversely, when the second housing 220 moves from the open position to the closed position, the second housing 220 has the ability to push the first connecting rod 940 toward the material 1000 via the second connecting rod 950. At the same time, the tension of the tension spring gradually decreases, and the tension spring recovers its deformation, thereby pulling the first connecting rod 940 toward the material 1000 until the first abutting part 620 reaches the abutting position, thus abutting the material 1000. However, this design is not limited to this. In some embodiments, the end of the second connecting rod 950 away from the hinge may not be rotatably connected to the second housing 220. In this case, the second connecting rod 950 has a protrusion. When the second housing 220 moves from the closed position to the open position, it can push against the protrusion on the second connecting rod 950, causing the second connecting rod 950 to move, thereby driving the first connecting rod 940 to move and causing the tension spring to deform. However, this design is not limited to this. In some embodiments, the transmission assembly 900 may also be other connecting rod structures.

[0085] In one embodiment, reference Figures 5 to 10 The transmission assembly 900 includes a transmission plate 910 slidably disposed on the first housing portion 210 and a protrusion 920 protruding from the transmission plate 910; wherein the first housing portion 210 is provided with a third guide rail 260, and the transmission plate 910 is slidably disposed on the third guide rail 260. The second housing portion 220 is provided with a second abutment portion 240. When the second housing portion 220 moves from the closed position to the open position, the second abutment portion 240 can abut against the protrusion 920, so that the transmission plate 910 slides along the first housing portion 210. At the same time, the elastic element undergoes elastic deformation. At this time, the transmission assembly 900 is not connected to the second housing portion 220. It can be understood that when the second housing portion 220 moves from the closed position to the open position, the second abutment portion 240 can abut against the protrusion 920, thereby using the protrusion 920 to... The transmission plate 910 is pushed to slide along the first housing 210. When the transmission plate 910 slides along the first housing 210, the elastic element undergoes elastic deformation, causing the first pushing part 620 to be in a released position. When the first pushing part 620 is in the released position, it does not press against the material. Further, in this embodiment, the elastic element is configured as a tension spring. When the second housing 220 moves from the closed position to the open position, the second housing 220 can pull the tension spring through the transmission plate 910, causing the tension spring to undergo elastic deformation. When the second housing 220 moves from the open position to the closed position, the tension spring gradually recovers its deformation and drives the transmission plate 910 to move towards the material 1000 until the first pushing part 620 reaches the pressing position and presses against the material 1000. It should be noted that in this embodiment, when the second shell 220 moves from the open position to the closed position, the second abutting part 240 does not abut against the protrusion 920. Furthermore, the transmission assembly 900 can be linked with the second shell 220, so that when the second shell 220 moves from the open position to the closed position, the first abutting part 620 can be moved to the abutting position simultaneously, thereby abutting against the material 1000.

[0086] In one embodiment, reference Figures 5 to 10The transmission assembly 900 further includes a first guide rail 930 disposed on the transmission plate 910. The first pushing part 620 is configured as a swing rod. One end of the swing rod is rotatably connected to the first shell 210, and the other end is rotatably connected to the first guide rail 930, and can slide along the first guide rail 930. It should be noted that when the second shell 220 moves back and forth between the open and closed positions, the swing rod can swing back and forth around its rotatable connection with the first shell 210. Further, in some embodiments, when the second cavity 610 is provided with a first cavity wall and a second cavity wall set at a preset angle, it should be noted that in some embodiments, the first cavity wall and the second cavity wall are set at a 90-degree angle. However, this design is not limited to this. In some embodiments, the first cavity wall and the second cavity wall can also be set at other angles, such as an acute angle less than 90 degrees. Of course, in some embodiments, depending on the shape of the material 1000, the angle between the first cavity wall and the second cavity wall can also be an obtuse angle. Furthermore, when the first pushing part 620 is in the pressing position, it can make the material 1000 press against the first cavity wall and the second cavity wall. It should be noted that at this time, the first cavity wall and the second cavity wall can restrict the material 1000 in two directions, minimizing the possibility of the material 1000 becoming loose or shaking.

[0087] In one embodiment (not shown), the image acquisition device 100 further includes a third driving module (not shown). The carrier 500 is movably disposed in the first cavity 230. The third driving module can drive the carrier 500 and the material 1000 disposed on the carrier 500 to move. It should be noted that when the third driving module drives the carrier 500 and the material 1000 disposed on the carrier 500 to move, the image acquisition module 400 can reacquire the image information of the material 1000. By adjusting the position of the material 1000, every detail can be captured at a high resolution, which helps to ensure the quality of the final synthesized image. At the same time, if some parts are found not to be captured clearly during the initial image capture, the third driving module can drive the carrier 500 and the material 1000 disposed on the carrier 500 to move to adjust the position of the material 1000, reposition the material 1000, and recapture the image, thereby acquiring the image information of the material 1000 from multiple angles.

[0088] Furthermore, in some embodiments (not shown), when the image acquisition device 100 further includes a third driving module and does not include the positioning structure 600, a rubber ring can be provided at the bottom of the material 1000. Under the action of the rubber ring, the friction between the bottom of the material 1000 and the receiving surface 510 can be increased. When the third driving module drives the carrier 500 to move, the carrier 500 can synchronously drive the material 1000 disposed on the receiving surface 510 to move, thereby adjusting the position of the material 1000. In this embodiment, the movement direction of the carrier 500 and the material 1000 can be multi-directional, and the third driving module can be a multi-directional driving module. The third driving module can include two linear driving structures, namely a first linear driving structure and a second linear driving structure, wherein the driving directions of the first linear driving structure and the second linear driving structure are perpendicular. However, in this embodiment, the structure of the third driving module can also be other structures, such as a driving structure that drives the carrier 500 to rotate. No specific limitation is made here, as long as it can drive the carrier 500 to move.

[0089] In some embodiments (not shown), when the image acquisition device 100 includes a third driving module and a positioning structure 600, the positioning structure 600 can be configured as multiple grippers mounted on the carrier 500. When the carrier 500 moves, the multiple grippers can move synchronously to clamp the material 1000 in real time, so that the material 1000 is in a clamped state at each moving position. In this embodiment, the moving directions of the carrier 500 and the material 1000 can be multi-directional, and the third driving module can be a multi-directional driving module. The third driving module can include two linear driving structures, namely a first linear driving structure and a second linear driving structure, wherein the driving directions of the first linear driving structure and the second linear driving structure are perpendicular. However, in this embodiment, the structure of the third driving module can also be other structures, and no specific limitation is made here, as long as it can drive the carrier 500 to move.

[0090] Furthermore, in some embodiments, reference is made to... Figure 12The image acquisition device 100 also includes a position detection component 700, which is used to detect the position of the second housing 220. Further, in some embodiments, the position detection component 700 includes a trigger part 710 and two photoelectric switches 720 disposed on the second housing 220, wherein the two photoelectric switches 720 are respectively configured to correspond to the open and closed positions of the second housing 220. The trigger part 710 is disposed on the second housing 220, and it is understood that the trigger part 710 can move with the second housing 220. When the second housing 220 moves to the open position, the trigger part 710 triggers one photoelectric switch 720; when the second housing 220 moves to the closed position, the trigger part 710 triggers the other photoelectric switch 720. It should be noted that after the photoelectric switch 720 is triggered, it can generate an electrical signal and feed the electrical signal back to other devices. In some embodiments, when the image acquisition device 100 includes a position detection component 700, the position sensor in the aforementioned embodiments can be reused with the position detection component 700. That is, the position detection component 700 can replace the position sensor to feed back signals to the electric telescopic pole.

[0091] Furthermore, in some embodiments, the image acquisition device 100 also includes a detection probe 1100 for detecting the material 1000 (see [link to image acquisition device]). Figure 8 The detection probe 1100 is used to detect whether material 1000 is placed on the receiving surface 510. Furthermore, when material 1000 is placed on the receiving surface 510, the detection probe 1100 can detect material 1000, that is, it can know that material 1000 is placed on the receiving surface 510. At this time, the detection probe will feed the information back to other devices. The detection probe 1100 can be configured as an infrared sensor or other detection probes.
