[0029] With the increasing level of industrial automation, CCD (Charge-Coupled Device, i.e., image sensor) is widely used in various fields.

[0030] CCD, also known as an industrial vision system, mainly consists of a CCD camera, lens, and signal processing system. It can directly convert optical signals into analog current signals. After amplification and analog-to-digital conversion, the current signals are used to acquire, store, transmit, process, and reproduce images.

[0031] However, CCD lenses are usually housed inside a casing. When the lens needs to be repositioned, the casing usually needs to be disassembled, making the lens repositioning process complicated and cumbersome, with low ease of operation and affecting the user experience.

[0032] Based on the above issues, please refer to the following: Figures 1 to 4 ,in, Figure 1 This is a three-dimensional structural schematic diagram of a lens adjustment device provided in an embodiment of the present invention; Figure 2 This is a three-dimensional structural diagram of the lens adjustment device provided in an embodiment of the present invention after removing the movable plate; Figure 3 This is a three-dimensional structural diagram of a portion of the lens adjustment device provided in an embodiment of the present invention; Figure 4 yes Figure 3 An enlarged view of part A of the lens adjustment device shown.

[0033] This utility model embodiment proposes a lens adjustment device 100, which is applied to a CCD camera and includes a housing 10 and an adjustment component 20. The housing 10 includes multiple support walls 11 and optical lenses 12, which together form a receiving space 101. The support walls 11 are provided with adjustment grooves 102, which are used to connect the receiving space 101 to the outside. The adjustment component 20 is disposed in the adjustment groove 102 and is used to connect the lens of the CCD camera. The adjustment component 20 can reciprocate along the adjustment groove 102 to adjust the relative positional relationship between the lens of the CCD camera and the optical lenses 12.

[0034] The lens adjustment device 100 is applied to a CCD camera and is designed to provide a stable working environment for the CCD camera lens and connect to the CCD camera lens so that users can adjust the position of the CCD camera lens to adapt to different working conditions.

[0035] The outer casing 10 is an external structural component of the lens adjustment device 100, used to define the external shape of the lens adjustment device 100 and to assemble with other external devices.

[0036] The housing 10 includes multiple support walls 11 and optical lenses 12. The support walls 11 are components that provide support in the housing 10, and the optical lenses 12 are components that the lens of the CCD camera needs to be aligned with. In this way, the multiple support walls 11 and optical lenses 12 together form a receiving space 101, in which the lens of the CCD camera can be housed to obtain a stable and relatively sealed working environment, reduce the interference of external factors on the operation of the CCD camera lens, and improve stability.

[0037] It should be noted that in these embodiments of the present invention, the outer shape of the outer shell 10 may be, but is not limited to, a cube, a cuboid, a cone, etc. Therefore, the outer shape of the outer shell 10 can be changed by increasing or decreasing the number of support walls 11 to adapt to different working environments.

[0038] The support wall 11 is provided with an adjustment groove 102, which is used to connect the receiving space 101 with the outside. That is, the adjustment groove 102 can be set on a certain support wall 11, so that the receiving space 101 can be connected to the outside through the adjustment groove 102. In this way, the adjustment groove 102 can be used to provide the possibility of position adjustment for the lens of the CCD camera installed in the receiving space 101.

[0039] An adjustment component 20 is disposed in the adjustment slot 102 and used to connect the lens of the CCD camera. In a possible implementation, a portion of the CCD camera lens structure can pass through the adjustment slot 102, extending from the receiving space 101 to the outside. In this case, the user can adjust the position of the CCD camera lens by pushing or pulling this portion of the lens structure. It is understood that in some embodiments of this invention, a connector can also be provided to connect to the CCD camera lens, with one end connected to the lens and the other end passing through the adjustment slot 102 and placed in the external environment. This also allows the user to conveniently adjust the position of the CCD camera lens.

[0040] The adjustment component 20 can reciprocate along the adjustment groove 102. In a possible implementation, the adjustment groove 102 is a groove structure that extends along a straight line. In this case, the adjustment component 20 can reciprocate along a straight line. Alternatively, in some embodiments, the adjustment groove 102 can also be set to extend along a curve. In this case, the adjustment component 20 can reciprocate along the curve to adjust the relative positional relationship between the lens of the CCD camera and the optical lens 12, thereby meeting different working conditions.

[0041] According to the lens adjustment device 100 provided by this utility model, by setting the adjustment component 20 in the adjustment groove 102 and connecting it to the lens of the CCD camera, the relative positional relationship between the lens of the CCD camera and the optical lens 12 can be changed by the reciprocating movement of the adjustment component 20 along the adjustment groove 102. This eliminates the step of adjusting the position of the CCD camera lens after disassembling the housing 10, reduces the difficulty of adjusting the lens of the CCD camera, and improves the user's convenience.

[0042] In some embodiments, the adjustment groove 102 extends in a straight line so that the adjustment component 20 can reciprocate along a first direction X; the first direction X is the direction that is closer to or farther from the optical lens 12.

[0043] In other words, in these embodiments of the present invention, the adjustment groove 102 is located on the support wall 11 which is not opposite to the optical lens 12, and its extension direction is not parallel to the optical lens 12. Thus, when the adjustment component 20 moves back and forth along the first direction X, it can move towards or away from the optical lens 12.

[0044] In some embodiments, the adjustment assembly 20 includes a first slider 21 and an actuating member (not shown). The first slider 21 is housed within a receiving space 101, and the actuating member is connected to the first slider 21 and is at least partially used to pass through the adjustment slot 102 to the outside.

[0045] The adjustment assembly 20 includes a first slider 21 and an operating member. The first slider 21 is connected to the operating member so that the user can control the first slider 21 to slide along a first direction X using the operating member. The operating member and the first slider 21 can be fixedly connected by welding or even integral molding to improve structural consistency. In some embodiments, a detachable connection can be provided between the operating member and the first slider 21 using threaded connections, screws, bolts, or other connecting components to facilitate maintenance and replacement of the first slider 21 or the operating member.

[0046] The first slider 21 is housed within the receiving space 101. The operating member is connected to the first slider 21 and is at least partially used to pass through the adjustment groove 102 to the outside. It is understood that in these embodiments of the present invention, the lens of the CCD camera can be connected to the first slider 21 so that the user can control the movement of the first slider 21 through the operating member, thereby driving the lens of the CCD camera to move.

[0047] In these embodiments of the present invention, the control element may be, but is not limited to, rod-shaped or block-shaped, so that the user can hold it during use.

[0048] In some embodiments, the adjustment component 20 further includes a second slider 23 slidably connected to the first slider 21, the second slider 23 being movable relative to the first slider 21 along a second direction Y; the second direction Y intersects the first direction X.

[0049] The second slider 23 is slidably connected to the first slider 21, and the second slider 23 can move relative to the first slider 21 along the second direction Y. In this way, the lens of the CCD camera can be connected to the second slider 23. When it is necessary to adjust the position of the CCD camera lens in the first direction X, the first slider 21 can be controlled to slide along the first direction X by the operating component, thereby driving the second slider 23 and the lens of the CCD camera to slide along the first direction X. When it is necessary to adjust the position of the CCD camera lens in the second direction Y, the second slider 23 can be controlled to slide relative to the first slider 21 in the second direction Y, thereby using the second slider 23 to drive the lens of the CCD camera to move in the second direction Y.

[0050] The second slider 23 and the first slider 21 are slidably connected in the second direction Y, which means that the second slider 23 and the first slider 21 are a moving whole. A possible implementation is that a sliding rod 104 can be provided on the first slider 21. The sliding rod 104 extends along the second direction Y and one end is connected to the first slider 21. The second slider 23 is slidably connected to the sliding rod 104.

[0051] In these embodiments of the present invention, the number of sliding rods 104 may be two, and the two sliding rods 104 are respectively slidably connected to the second slider 23 to improve the stability of the second slider 23 when sliding along the second direction Y.

[0052] The second direction Y intersects with the first direction X, meaning that in these embodiments of the present invention, the first slider 21 and the second slider 23 are respectively used to drive the lens of the CCD camera to move along the two intersecting directions, so that the lens of the CCD camera can freely adjust its position in the plane formed by the first direction X and the second direction Y.

[0053] Exemplary examples, in these embodiments of the present invention, the first direction X can be set to be perpendicular to the second direction Y, so that when the first slider 21 and the second slider 23 work independently, they do not affect the relative position of the CCD camera lens with the optical lens 12 in the other direction. That is, when the user operates the first slider 21 to change its position along the first direction X, it will not affect the relative position of the CCD camera lens with the optical lens 12 in the second direction Y; correspondingly, when the user operates the second slider 23 to move its position relative to the first slider 21 in the second direction Y, it will not affect the relative position of the CCD camera lens with the optical lens 12 in the first direction X.

[0054] In some embodiments, the adjustment component 20 further includes a third slider 24 slidably connected to the second slider 23, the third slider 24 being movable relative to the second slider 23 along the third direction Z, and the lens of the CCD camera being connected to the third slider 24; the plane formed by the first direction X and the second direction Y intersects the third direction Z.

[0055] The third slider 24 is slidably connected to the second slider 23, and the third slider 24 can move relative to the second slider 23 along the second direction Z. In this way, the lens of the CCD camera can be connected to the third slider 24. When it is necessary to adjust the position of the CCD camera lens in the third direction X, the sliding of the third slider 24 relative to the second slider 23 in the third direction Z can be controlled, thereby using the third slider 24 to drive the CCD camera lens to move in the third direction Z.

[0056] In these embodiments of the present invention, the user can adjust the position of the CCD camera lens in three intersecting directions by operating the first slider 21, the second slider 23 and the third slider 24 respectively, thereby achieving omnidirectional adjustment of the CCD camera lens.

[0057] In some embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0058] In this way, when the user adjusts the position of the CCD camera lens in a single direction, it will not affect the relative position of the CCD camera lens with the optical lens 12 in the other two directions, further improving the precision of the CCD camera lens position adjustment and making it more reliable.

[0059] In some embodiments, the support wall 11 includes a first wall 111 having a through hole 103 and a movable plate 112. The through hole 103 is used to connect the receiving space 101 with the outside. The movable plate 112 is movably connected to the first wall 111 so that the through hole 103 can switch between an open state and a closed state.

[0060] The support wall 11 includes a first wall 111 with a through hole 103 and a movable plate 112. The through hole 103 is designed to provide a window for the user to adjust the lens of the CCD camera located in the receiving space 101 through the window, which reduces the difficulty for the user to adjust the position of the CCD camera lens and provides the user with a better user experience.

[0061] The movable plate 112 is movably connected to the first wall 111 to switch the through hole 103 between an open and closed state. When the user does not need to adjust the position of the CCD camera lens, the movable plate 112 can be controlled to move relative to the first wall 111, so that the movable plate 112 moves to a position covering the through hole 103, thereby isolating the accommodating space 101 from the external environment, improving the stability of the accommodating space 101 environment, and providing a stable and relatively sealed working environment for the CCD camera lens. When the user needs to adjust the position of the CCD camera lens, the movable plate 112 can be controlled to move relative to the first wall 111, so that the movable plate 112 moves to a position that is misaligned with the through hole 103, thereby exposing the through hole 103 and allowing the accommodating space 101 to communicate with the external environment. At this time, the user can adjust the relative position between the CCD camera lens and the optical lens 12 in the accommodating space 101 through the through hole 103 window.

[0062] The movable plate 112 is movably connected to the first wall 111. A possible implementation is as follows:

[0063] In some embodiments, the movable plate 112 and the first wall 111 can be connected by a connector. That is, in these embodiments of the present invention, the movable plate 112 and the first wall 111 can be detachably connected by a connector such as screws or bolts.

[0064] In some embodiments, the movable plate 112 can be slidably connected to the first wall 111. That is, in some embodiments, the cross-sectional shape of the through hole 103 can be rectangular. In this case, the cross-sectional shape of the movable plate 112 can be slightly larger than the cross-sectional shape of the through hole 103, and the movable plate 112 and the first wall 111 are connected by a sliding connection. When the movable plate 112 slides to the position covering the through hole 103, the through hole 103 can be covered by the movable plate 112. When the movable plate 112 slides to the position that is misaligned with the through hole 103, the through hole 103 can be exposed, thus realizing the switching between the open state and the closed state of the through hole 103.

[0065] In some embodiments, the movable plate 112 can be hinged to the first wall 111. That is, by setting a hinge on one side of the movable plate 112 and connecting it to the first wall 111 through the hinge, the movable plate 112 can rotate along the hinge, thereby making the movable plate 112 a "flip-top" structure, thus realizing the switching of the through hole 103 between the open state and the closed state.

[0066] In some embodiments, the support wall 11 further includes a second wall 113, and there is an angle between the plane where the first wall 111 is located and the plane where the second wall 113 is located; the adjustment groove 102 is disposed on the second wall 113.

[0067] In these embodiments of the present invention, the second wall 113 and the first wall 111 are two wall structures that are in an intersecting state among a plurality of supporting walls 11.

[0068] For example, in an embodiment where the structure of the housing 10 is rectangular, the housing 10 may have a top wall, a bottom wall, and four side walls connecting the top wall and the bottom wall. In this case, the optical lens 12 may be positioned at the top wall of the housing 10. The first wall 111 may be set as any side wall, so that by setting an adjustment groove 102 extending along the first direction X, the lens of the CCD camera in the receiving space 101 may move along the adjustment groove 102 toward or away from the optical lens 12 (top wall).

[0069] At this time, the second wall 113 can be set as either a side wall or a bottom wall. Preferably, the second wall 113 can be set as a side wall adjacent to the aforementioned first wall 111 to reduce the impact of the through hole 103 on the adjustment groove 102, reduce the possibility of mutual interference in different displacement directions when the user adjusts the position of the CCD camera lens through the through hole 103 and the adjustment groove 102, and improve reliability.

[0070] This utility model embodiment also provides a CCD camera, which includes a lens adjustment device 100 as provided in any of the foregoing embodiments.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
