Description

Technical Field

[0001] The present disclosure relates to the technical field of equipment installation, and particularly to a mechanism for adjusting a camera. Background Art

[0002] An industrial line scan camera is a high-precision imaging device widely used in fields such as automated inspection, quality control, and machine vision. Its core function is to capture images through linear scanning to obtain detailed features of the object to be measured. Line scan cameras are usually equipped with high-resolution photosensitive elements that can stably capture images during high-speed movement, which is crucial for ensuring image quality. In industrial applications, the adjustment of line scan cameras is very critical for achieving accurate image capture. The camera needs to be precisely aligned with the object to be measured to ensure image clarity and accuracy. In addition, the adjustment of the position, angle, and height of the camera is crucial for obtaining high-quality image data, because any deviation may lead to image distortion or omission of important information.

[0003] In the existing technology, the adjustment of industrial line scan cameras usually relies on complex mechanical structures and manual adjustment. This includes using multiple guide rails, sliders, and adjustment screws to achieve precise positioning of the camera in space. For example, the system described in CN217234965U uses multiple guide rails for guidance to achieve the front-back, left-right, and up-down movement of the camera. In addition, some systems may include fine-tuning knobs and locking mechanisms to fine-tune the angle and position of the camera. These adjustment mechanisms usually require manual operation, and the operator needs to make careful adjustments based on experience to ensure the correct alignment of the camera.

[0004] There are some significant technical problems in the existing camera adjustment methods, especially in terms of the cumbersome installation and debugging process and the flexibility of adjustment. Existing adjustment systems usually require multiple steps to complete the installation and adjustment of the camera. This is not only time-consuming but also requires the operator to have a high level of skill and experience. For example, a system using multiple guide rails and sliders may require precise alignment and adjustment, which is impractical in a rapidly changing production environment. Existing adjustment mechanisms often lack flexibility and are difficult to achieve fine-tuning of the camera in a specific direction. For example, existing technologies may be difficult to achieve the adjustment of the swing of the camera in two mutually perpendicular vertical planes, which is insufficient for certain specific application scenarios (such as the detection of complex objects that require precise alignment). In some cases, the existing adjustment mechanisms may not provide sufficient stability after adjustment, resulting in displacement or jitter during camera use, affecting image quality. In summary, although the existing technologies can achieve camera adjustment to a certain extent, they have obvious limitations in terms of operation convenience, adjustment accuracy, and stability. Summary of the Utility Model

[0005] To solve the above technical problems, embodiments of the present disclosure are expected to provide a mechanism for adjusting a camera to solve the above problems, which is of great significance for improving the application efficiency and image quality of industrial line-scan cameras.

[0006] The technical solution of the present disclosure is implemented as follows:

[0007] Embodiments of the present disclosure provide a mechanism for adjusting a camera, the mechanism comprising:

[0008] A sliding table;

[0009] A first member configured to be movable along the sliding table;

[0010] A second member configured to move with the first member and be rotatable relative to the first member about a first axis, wherein the first axis is perpendicular to the moving direction of the first member;

[0011] A third member configured to move with the second member and be rotatable relative to the second member about a second axis, wherein the second axis is perpendicular to the first axis;

[0012] A fourth member configured to move with the third member and be movable relative to the third member in a plane parallel to the first axis and the second axis, wherein the camera is mounted on the fourth member.

[0013] Embodiments of the present disclosure provide a mechanism for adjusting a camera, allowing the camera to be adjusted in height in the vertical direction, swung in the vertical plane, and moved in the horizontal plane. The adjustment of each step is independent and does not affect the results of previous adjustments, ensuring the accuracy and reliability of the adjustment. The mechanism can achieve the swinging adjustment of the camera in the vertical plane, enabling the camera to easily be adjusted to a position parallel to the object to be measured, improving the image quality and accuracy. The mechanism further enhances the adjustment flexibility of the camera in the horizontal plane, enabling the camera to more easily be adjusted to the target orientation to meet different shooting requirements.

[0016] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure.

[0017] With the increasing demands for industrial automation and precision manufacturing, the requirements for the accuracy and efficiency of camera adjustment technologies are also getting higher and higher. In existing camera adjustment systems, although they can meet the basic adjustment needs to a certain extent, their limitations gradually emerge in actual operations. For example, the cumbersome installation and debugging process not only consumes valuable time and human resources but also requires high skills from the operator, which limits their applicability in rapidly changing production environments. In addition, existing technologies have difficulties in achieving fine adjustment of the camera in a specific direction, especially in the adjustment of the swing in two mutually perpendicular vertical planes, which directly affects the performance of the camera in specific application scenarios such as complex object detection. At the same time, the stability of existing adjustment mechanisms is insufficient after adjustment, and it is easy to have displacement or jitter during the use of the camera, affecting the image quality.

[0018] To address these problems, referring to Figure 1 , an embodiment of the present disclosure provides a mechanism 1 for adjusting a camera C, and the mechanism 1 may include:

[0019] A slide table 10, and the slide table 10 may be, for example, a high-precision electric slide table;

[0020] A first member 11, and the first member 11 is configured to be able to move along the slide table 10. For example, as specifically shown in Figure 1 , the first member 11 moves in the Z-axis direction, that is, the vertical direction. In addition, the first member 11 may be in the shape of a flat plate, and the plane where the flat plate is located is parallel to the moving direction;

[0021] A second member 12, and the second member 12 is configured to move together with the first member 11 and be able to rotate relative to the first member 11 about a first axis X1. Wherein, the first axis X1 is perpendicular to the moving direction of the first member 11. Specifically, as shown in Figure 1 , the first axis X1 may be parallel to the Y-axis. In addition, the second member 12 may also be in the shape of a flat plate and can be rotated to be parallel to the flat-plate-shaped first member 11. The first member 11 may be provided with a first fixing block 110 for fixing a pin shaft. In addition, the number of the first fixing blocks 110 may be two and are arranged at both ends of the pin shaft. The second member 12 may be formed with a through hole. After the pin shaft passes through the through hole, the second member 12 can rotate relative to the first member 11 about the pin shaft. That is to say, the above-mentioned first axis X1 is the longitudinal axis of the pin shaft, or in other words, the pin shaft is collinear with the first axis X1 shown in Figure 1 ;

[0022] The third member 13 is configured to move together with the second member 12 and be rotatable relative to the second member 12 about a second axis X2, where the second axis X2 is perpendicular to the first axis X1. Specifically, as shown in Figure 1 , the second axis X2 may be parallel to the X-axis. Additionally, the third member 13 may include a flat plate member, and during the rotation of the third member 13, the flat plate member is always parallel to the flat second member 12. Additionally, referring to Figure 2 , a through hole 12T may be formed below the second member 12, and a threaded hole 13T may be formed at the corresponding position of the third member 13. After using a screw to pass through the through hole 12T and screw it into the threaded hole 13T, the third member 13 can rotate relative to the second member 12 about the screw. That is to say, the above-mentioned second axis is the longitudinal axis of the screw, or rather, the screw is collinear with the second axis X2 shown in Figure 1 ;

[0023] The fourth member 14 is configured to move together with the third member 13 and be movable relative to the third member 13 in a plane P parallel to the first axis X1 and the second axis X2. Wherein, the camera C is mounted on the fourth member 14. Specifically, as shown in Figure 1 , the plane P may be defined by the X-axis and the Y-axis as parallel.

[0024] The mechanism 1 for adjusting the camera C provided by the embodiments of the present disclosure realizes the precise adjustment of the camera C in three-dimensional space through its unique multi-layer mechanical structure design, while ensuring the simplicity and stability of the adjustment process. Specifically, through the design of the multi-layer mechanical structure of the mechanism 1, each component can be independently adjusted and fixed. For example, the first component 11 can move along the slide 10 to realize the height adjustment of the camera C in the vertical direction (Z-axis); the second component 12 can rotate relative to the first component 11 around the first axis X1 to realize the swing adjustment of the camera C in the first vertical plane (XZ plane); the third component 13 can rotate relative to the second component 12 around the second axis X2 to realize the swing adjustment of the camera C in the vertical plane (YZ plane); the fourth component 14 can move relative to the third component 13 in the plane P to realize the adjustment of the camera C in the horizontal plane (XY plane). This design ensures that when adjusting any component, the adjustment result of the previous stage will not be affected, thus ensuring the accuracy and reliability of the adjustment. In addition, through the design of the second component 12 and the third component 13, the mechanism 1 can realize the swing adjustment of the camera C in the XZ plane and the YZ plane. This swing adjustment is jointly realized by the rotation of the second component 12 relative to the first component 11 around the first axis X1 and the rotation of the third component 13 relative to the second component 12 around the second axis X2. This design enables the camera C to be easily adjusted to a position parallel to the object to be measured, thereby improving the quality and accuracy of the image. In addition, the design of the fourth component 14 enables the camera C to perform a moving adjustment in the XY plane. This moving adjustment is realized by the movement of the fourth component 14 relative to the third component 13 in the plane P. This design further enhances the adjustment flexibility of the camera C, enabling the camera C to be more easily adjusted to the target orientation to meet different shooting requirements. In summary, the mechanism 1 for adjusting the camera C provided by the embodiments of the present disclosure, through its innovative multi-layer mechanical structure design, not only realizes the precise adjustment of the camera C in three-dimensional space, but also improves the simplicity and stability of the adjustment process, meeting the adjustment requirements of industrial line scan cameras in various application scenarios.

[0025] In a specific embodiment of the present disclosure, referring to Figure 1 , the mechanism 1 may further include a first knob 15, and the rotation of the second component 12 in the first rotation direction is realized by screwing the first knob 15.

[0026] Specifically, as shown in Figure 1 , the first component 11 may be provided with a second fixing block 111, a threaded hole may be formed in the second fixing block 111, and the first knob 15 may cooperate with the threaded hole, so that when the first knob 15 is screwed, the first knob 15 will translate along the longitudinal axis of the threaded hole, thereby driving the second component 12 to rotate.

[0027] The knob usually provides stable resistance and definite steps, enabling the operator to feel the amplitude of each adjustment, thus achieving more delicate and accurate adjustment. Additionally, the knob is an intuitive and easy-to-operate control element. Compared with methods that require complex tools or multi-step adjustments, the knob allows the user to operate with one hand and quickly adjust the angle of the camera C, greatly simplifying the adjustment process. Since the rotation of the knob can usually be controlled very precisely, the position deviation caused by improper estimation or operation can be reduced. The introduction of the knob makes the adjustment process faster. Without spending time on complex settings or alignment, the user can quickly adjust the camera to the desired position. The user can directly perceive the adjustment state of the camera by rotating the knob, thereby enhancing the operation satisfaction. The knob has a simple structure and is relatively easy and inexpensive to maintain or replace even after long-term use.

[0028] In a specific embodiment of the present disclosure, referring to Figure 1 , the mechanism 1 may further include a first spring 16. The first spring 16 is configured to elastically deform when the second member 12 rotates in the first rotation direction, and the second member 12 rotates in the second rotation direction opposite to the first rotation direction through the elastic restoring force generated by such elastic deformation.

[0029] In the case where the above-mentioned first spring 16 is provided, by screwing the first knob 15, the operator can achieve precise adjustment of the second member 12 in two rotation directions through a single knob operation without additional control elements or complex operation steps. The configuration of the first spring 16 enables the second member 12 to automatically reset through the restoring force generated by the elastic deformation of the spring when rotating in the fourth rotation direction opposite to the third rotation direction. This automatic reset function greatly simplifies the operation process, especially in application scenarios where the position of the camera C needs to be frequently adjusted, saving a large amount of operation time and labor intensity. The operation method of a single knob provides the user with an intuitive and simple operation experience. The user only needs to screw the first knob 15 to achieve the rotation of the second member 12 in two directions without worrying about complex control logic or multi-step operations. The elastic restoring force of the first spring 16 provides stable resistance, making the rotation of the second member 12 smoother and more controllable. This stable resistance feedback helps the operator more precisely control the rotation angle of the second member 12, thereby improving the adjustment accuracy of the entire camera adjustment mechanism 1. The use of the first spring 16 not only provides the automatic reset function but also can provide additional stability during the rotation of the second member 12. The elastic action of the spring helps to reduce the position deviation of the mechanism 1 caused by accidental collision or improper operation, thus ensuring the stability of the camera C and the image quality.

[0030] Specifically, in Figure 1In the case shown, when the first knob 15 is tightened, the upper end of the second member 12 is driven to move in the negative direction of the X-axis, while the lower end of the second member 12 moves in the positive direction of the X-axis. When the first knob 15 is loosened, the upper end of the second member 12 moves in the positive direction of the X-axis under the action of the first spring 16, and the lower end of the second member 12 moves in the negative direction of the X-axis. Additionally, this can ensure that the lower end face of the camera C is parallel to the X-axis.

[0031] In addition, although not shown in the drawings, it can be understood that the first spring 16 can be arranged to surround, for example, a stud fixed to the second member 12, which can ensure that the working path of the first spring 16 is close to a straight line, helping to reduce bending when stressed.

[0032] In a specific embodiment of the present disclosure, referring to Figure 2 , the first member 11 may be formed with a first recess 11R, Figure 1 and the first spring 16 shown in

[0033] is inserted into the first recess 11R. The first member 11 is designed with the first recess 11R, which is specifically used to accommodate the first spring 16. The first recess 11R provides a stable installation space for the spring, ensuring that the spring will not shift or fall off during the operation of the mechanism. By inserting the first spring 16 into the first recess 11R, both ends of the spring can closely cooperate with the side walls of the recess to form a firm fixing structure. This design not only prevents the accidental detachment of the spring but also enhances the structural stability of the entire mechanism. The stable installation of the first spring 16 reduces the risk of operation interruption or equipment damage caused by the detachment of the spring. When the operator adjusts the camera C, there is no need to worry about the stability of the spring and can focus more on the adjustment task itself. The stable installation of the first spring 16 simplifies the maintenance process of the mechanism 1. Since the spring is not easily detached, maintenance personnel can more quickly confirm the state of the spring during equipment inspection and maintenance, reducing maintenance time and costs. The design of the first recess 11R takes into account the long-term operation requirements of the spring, and the structure of the recess can effectively reduce the wear of the spring during long-term use, thereby enhancing the durability and service life of the entire mechanism.

[0034] In a specific embodiment of the present disclosure, referring to Figure 2 , the mechanism 1 may further include a second knob 17 and a third knob 18. The third member 13 rotates in the third rotation direction by screwing the second knob 17, and the third member 13 rotates in the second direction opposite to the first rotation direction by screwing the third knob 18.

[0035] In addition, the specific setting methods of the second knob 17 and the third knob 18 and the method of rotating the third member 13 can be similar to those of the first knob 15. For example, two fixing blocks can be provided on the second member, and threaded holes respectively cooperating with the second knob 17 and the third knob 18 can be formed in these two fixing blocks. When the second knob 17 and the third knob 18 are respectively screwed, the second knob 17 and the third knob 18 will respectively translate along the longitudinal axis of the threaded hole, thereby driving the third member 13 to rotate.

[0036] Similar to the first knob 15 rotating the second member 12, when the third member 13 is rotated by the second knob 17 and the third knob 18, advantages such as precise control, easy operation, reduced error, improved efficiency, and enhanced user experience can be obtained during the adjustment process.

[0037] Specifically, in the Figure 1 shown case, when the second knob 17 is tightened, the upper end of the third member 13 is driven to move in the negative direction of the Y-axis, while the lower end of the third member 13 moves in the positive direction of the Y-axis. When the third knob 18 is tightened, the upper end of the third member 13 is driven to move in the positive direction of the Y-axis, while the lower end of the third member 13 moves in the negative direction of the Y-axis. In addition, this can ensure that the lower end face of the camera C is parallel to the Y-axis. In addition, to ensure that the third member 13 can rotate, the third knob 18 can be loosened while the second knob 17 is tightened, and the second knob 17 can be loosened while the third knob 18 is tightened.

[0038] In a specific embodiment of the present disclosure, referring to Figure 1 , the mechanism 1 may further include a fourth knob 19, and the fourth member 14 moves along the first moving direction by screwing the fourth knob 19.

[0039] Similar to the first knob 15, the second knob 17, and the third knob 18, when the fourth member 14 is moved by the fourth knob 19, advantages such as precise control, easy operation, reduced error, improved efficiency, and enhanced user experience can be obtained during the adjustment process.

[0040] Regarding the specific setting method of the fourth knob 19 and the method of moving the fourth member 14, as shown in Figure 1 , the fourth member 14 can be formed with a threaded hole cooperating with the fourth knob 19, so that when the fourth knob 19 is screwed, the fourth knob 19 can translate along the longitudinal axis of the threaded hole. On the other hand, the fourth knob 19 can be abutted against the third member 13, so that the fourth member 14 is driven to move. In addition, as shown in Figure 1 , the number of the fourth knobs 19 can be two, and the number of the corresponding threaded holes can also be two.

[0041] In a specific embodiment of the present disclosure, referring to Figure 1 , the mechanism 1 may further include a second spring 20 configured to elastically deform when the fourth member 14 moves in the first moving direction, and the fourth member 14 moves in a second moving direction opposite to the first moving direction to achieve an elastic restoring force generated by such elastic deformation.

[0042] Similar to the first spring 16, the arrangement of the second spring 20 enables advantages such as two-way movement control, automatic reset, simple operation, improved adjustment accuracy, and enhanced stability to be obtained during the adjustment process.

[0043] Specifically, in the case shown in Figure 1 , when the fourth knob 19 is tightened, the fourth member 14 is driven to move in the negative direction of the X-axis. When the fourth knob 19 is loosened, the fourth member 14 moves in the positive direction of the X-axis under the action of the second spring 20. Additionally, this can ensure that the camera C moves in the direction of the X-axis.

[0044] In a specific embodiment of the present disclosure, referring to Figure 2 , the third member 13 may be formed with a second recess 13R, Figure 1 and the second spring 20 shown in

[0045] is inserted into the second recess 13R. Similar to the first recess 11R, the arrangement of the second recess 13R enables advantages such as a firm spring installation, enhanced structural stability, improved operation safety, and simplified maintenance process to be obtained.

[0046] In a specific embodiment of the present disclosure, the third member 13 may be formed with a first guiding portion, and the fourth member 14 may be formed with a second guiding portion. The first guiding portion and the second guiding portion are matched to guide the movement of the fourth member 14. As shown in Figure 1 It is easily understood that the first guiding portion may be, for example, a guiding groove formed on the third member 13, and the second guiding portion may correspondingly be a guiding protrusion formed on the fourth member 14 and matching the guiding groove.

[0047] The third member 13 is formed with a first guiding portion, and the fourth member 14 is formed with a second guiding portion that matches it. This design of the matching guiding portions ensures that the movement of the fourth member 14 strictly follows the path set by the first guiding portion, thus ensuring that the moving direction of the camera C is consistent with the operator's expectation. By the combined use of the first guiding portion and the second guiding portion, the mechanism 1 can prevent the deviation or tilt that may occur when adjusting the position of the camera C. This precise guiding mechanism reduces the human operation error and improves the accuracy of adjustment. The precise design of the guiding portions makes the adjustment process of the camera C smoother and faster. The operator can quickly adjust the camera C to the required position without repeatedly adjusting to eliminate the deviation, thereby improving the overall work efficiency. The cooperation of the first guiding portion and the second guiding portion not only improves the adjustment accuracy but also enhances the stability of the mechanism 1. The stability of the camera C during the adjustment process is crucial for ensuring the image quality and shooting effect.

[0048] In a specific embodiment of the present disclosure, referring to Figure 1 , the mechanism 1 may further include a support member 21, and the support member 21 is used to support the end of the camera C to prevent the end of the camera C from jittering after the camera C is adjusted in place.

[0049] The support member 21 is specifically used to support the end of the camera C after the camera C is adjusted to the desired position. This design reduces the jitter of the end of the camera C when it is subjected to external forces or vibrations by providing an additional support point, thereby improving the stability of the camera. After the camera C is adjusted in place, the support member 21 can firmly support the end of the camera, preventing the displacement of the camera caused by accidental collisions or improper operations. This stable support function is crucial for ensuring the accuracy and consistency of the camera position. The design of the support member 21 effectively reduces the jitter of the camera C during use, especially when shooting at high speeds or working in an unstable environment. Reducing jitter helps to improve the clarity and quality of the image. By ensuring the stability of the camera C, the support member 21 helps to reduce the image blur or distortion caused by camera jitter, which enables the camera to capture clearer and more accurate images and improves the image quality.

[0051] As described above, it is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
