[0022] Example:

[0023] like Figure 1 and 2 As shown, in this embodiment, the image acquisition device includes: a shell 1 formed with a accommodating cavity 11, a lens assembly 2 having a first magnetic component 21, and an operating component 3; a placement area for placing the detection target 5 is provided at the bottom of the accommodating cavity 11, the lens assembly 2 is located in the accommodating cavity 11, and the shooting direction of the lens assembly 2 is toward the placement area; the operating component 3 is located outside the shell 1, and the operating component 3 has a second magnetic component 31 for mutual attraction with the first magnetic component 21, and the lens assembly 2 is attached to the inner wall of the shell 1 under the mutual attraction of the first magnetic component 21 and the second magnetic component 31; the operating component 3 is used to drive the lens assembly 2 to move under the action of external force.

[0024] Specifically, the detection target 5 of this embodiment can be a passport, a driver's license, a visa, a check, a banknote, or other objects that need to be authenticated. The image information of the detection target 5 can be collected through the lens assembly 2. The magnetic pole at the top of the first magnetic component 21 and the magnetic pole at the bottom of the second magnetic component 31 have opposite polarities. The lens assembly 2 can be connected to the inner wall of the housing 1 through the mutual attraction of the first magnetic component 21 and the second magnetic component 31; the user can also drive the lens assembly 2 to move in a plane parallel to the placement area by moving the operating component 3, thereby ensuring that the lens assembly 2 can completely collect images of various areas of the detection target 5. The overall structure of the image acquisition device is simple, and the production, processing, and assembly costs are low.

[0025] In this embodiment, a guide groove 4 is provided on the top of the housing 1, and the operating component 3 is slidably matched with the guide groove 4. That is, a guide member is fixed on the top of the housing, and a guide groove 4 is formed on the guide member, and the operating component 3 is slidably matched with the guide groove 4; the second magnetic member 31 in the operating component 3 can be sucked and connected to the top of the accommodating cavity 11. When the user operates the operating component 3, the guide groove 4 can guide the user's pushing operation, preventing the user from arbitrarily moving the operating component 3 and causing part of the detection target 5 to not be captured, thereby improving the efficiency of image capture.

[0026] Further, in the present embodiment, a limiting edge 41 extending inward is provided at the notch of the guide groove 4; the operating assembly 3 further comprises an operating member 32, and the second magnetic member 31 is embedded at the lower end of the operating member 32; an abutting portion 321 is formed on the peripheral side of the lower end of the operating member 32, and the upper side of the abutting portion 321 abuts against the lower side of the limiting edge 41, and the upper end of the operating member 32 passes through the opening of the guide groove 4 and extends to the outside of the guide groove 4. Through the cooperation between the limiting edge 41 and the abutting portion 321, the operating member 32 and the second magnetic member 31 can be restricted to the top of the housing 1, thereby preventing the second magnetic member 31 from being taken in at will and causing the lens assembly 2 to lose the magnetic attraction and fall. In some specific embodiments, a groove matching the shape of the second magnetic member 31 is provided at the lower end of the operating member 32, and the second magnetic member 31 is engaged with the groove, thereby realizing a stable connection between the second magnetic member 31 and the operating member 32. Of course, in some other embodiments, the second magnetic member 31 and the operating member 32 may also be fixed together by gluing, which is not limited here.

[0027] In some embodiments, the guide path of the guide groove 4 can be in the shape of a rounded quadrilateral or a straight line, so that during the operation of the image acquisition device, after the operating component 3 moves along the guide path of the guide groove 4 once, the area scanned by the lens 23 can completely cover the entire placement area. In a specific embodiment, the shell 1 can be set as a cube as a whole, and the guide groove 4 is a rounded quadrilateral, which is more conducive to the lens 23 capturing the image of each area of ​​the detection target 5, and the rounded corners and straight edges of the guide groove 4 are naturally transitioned, so that the movement operation of the operating component 3 can be smoother. Of course, in some other embodiments, the guide groove 4 can also be a quadrilateral, a circle, an ellipse, a "cross" shape, etc., which can be set according to needs in actual applications and are not limited here.

[0028] In this embodiment, the lens assembly 2 also includes a fixing member 22 connected to the top of the accommodating cavity 11, a lens 23 connected to the bottom side of the fixing member 22, and the first magnetic member 21 is embedded in the top side of the fixing member 22. A groove that matches the shape of the first magnetic member 21 can be provided at the top of the fixing member 22, and the second magnetic member 31 is fixed by being engaged with the corresponding groove. It can be understood that in some embodiments, the fixing member can be obtained by integral injection molding, and the second magnetic member 31 can be pre-embedded in the mold during the injection molding process of the fixing member 22, so that after the injection molding process is completed, the fixing member 22 and the second magnetic member 31 can be obtained as a connecting member combined into one, and the structure is more stable and the processing cost is low. In this embodiment, one or more first magnetic members 21 can be provided, and correspondingly, one or more second magnetic members 31 can also be provided. Of course, in some other embodiments, while providing a second magnetic member 31, multiple first magnetic members 21 can also be provided, and the projection area of ​​the second magnetic member 31 can be greater than the sum of the projection areas of all first magnetic members 21, which is not limited here. Preferably, four evenly and spaced first magnetic members 21 are fixed to the top side of the fixing member 22, which is beneficial to improving the attraction stability between the lens assembly 2 and the operating assembly 3, avoiding rotation or displacement of the lens 23 during the movement of the lens 23, thereby affecting the image acquisition progress, and at the same time, avoiding the lens 23 from rotating arbitrarily and causing blind spots to be missed.

[0029] In this embodiment, the housing 1 is opaque, which can prevent the adverse effects of external light on the formation of the image. Further, in this embodiment, the housing 1 is one of aluminum, copper, and plastic, preferably aluminum with a smooth top surface. The material is cheap and easy to obtain, and will not interact with the magnetic attraction, making it easy to move the operating component 3.

[0030] In the present embodiment, the shell 1 is further provided with a side door 12. That is, the shell 1 includes a main shell with an opening formed on one side and a side door 12 hinged at the opening of the main shell, and the shape of the opening is exactly adapted to the shape of the side door 12; when the side door 12 is opened, the detection target 5 can be put in or taken out through the opening; when the side door 12 is closed, it can be enclosed with the main shell to form a closed and light-proof accommodating chamber 11 to prevent external light from interfering with image acquisition. Of course, in some other embodiments, the side door 12 can also be set in the form of a sliding door, that is, a slide groove adapted to the side door 12 can be set on the main shell, so that the side door 12 can slide along the slide groove under the action of external force, thereby realizing the connection and blocking between the accommodating chamber 11 and the outside of the shell 1, which is not limited here.

[0031] In this embodiment, the anti-counterfeiting detection system includes a control module and an image acquisition device, the image acquisition device includes a housing 1 and a lens assembly 2, and the control module is electrically connected to the lens assembly 2 or wirelessly connected. Specifically, the control module can be a main control module integrated on the image acquisition device, or it can be a processing terminal independent of the image acquisition device, which is not limited here. A light source can also be provided in the image acquisition device, and the light source is electrically connected to the control module; the light source can emit light of a required wavelength and / or required color to meet the shooting requirements of the lens assembly 2, so that the lens assembly 2 can accurately capture the image information of the detection target 5 and transmit the detected image information to the control module; thereby, the control module can further identify and process the captured image to determine the authenticity of the detection target 5. In addition, the control module can also generate an authenticity identification analysis report corresponding to the detection target 5.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
