Description

Technical Field

[0001] This utility model relates to the field of industrial camera focusing technology, and in particular to a camera three-dimensional angle adjustment mechanism. Background Technology

[0002] In the fields of machine vision, precision measurement, and optical inspection, cameras, as core image acquisition components, require precise adjustment of their spatial pose. Existing camera angle adjustment mechanisms often employ single-dimensional adjustment methods, such as supporting only pitch or horizontal movement, making it difficult to achieve comprehensive control of three-dimensional spatial angles. While some structures attempt to integrate multi-directional adjustment functions, they typically suffer from loose structures, insufficient rigidity, and accumulated transmission errors, resulting in limited adjustment accuracy and susceptibility to displacement deviations under vibration, affecting imaging stability. Pitch adjustment mechanisms, in particular, commonly employ single-point drive or asymmetrical force application, easily causing uneven force on the adjustment plate, leading to deformation or jamming. This not only reduces the consistency and repeatability of angle control but may also cause optical center shift, failing to meet the stringent attitude stability requirements of high-resolution imaging systems. Furthermore, traditional adjustment mechanisms often fail to adequately consider modular layout and space utilization efficiency, resulting in a bulky overall structure with low integration, limiting their application in compact devices. Therefore, there is an urgent need for a camera three-dimensional angle adjustment mechanism that is compact, has excellent rigidity, supports multi-degree-of-freedom precision adjustment, and can work stably for a long time, so as to improve the system adaptability and reliability in complex application scenarios.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-4As shown, in one embodiment of this utility model, a three-dimensional angle adjustment mechanism for a camera is disclosed, comprising a base plate 1, a vertical adjustment module 2, a pitch adjustment module 3, a horizontal adjustment module 4, and a camera module 5. The vertical adjustment module 2 is mounted on the base plate 1, the pitch adjustment module 3 is mounted on the vertical adjustment module 2, the horizontal adjustment module 4 is mounted on the pitch adjustment module 3, and the camera module 5 is mounted on the horizontal adjustment module 4. The pitch adjustment module 3 includes a connecting rib 31, a pitch adjustment plate 32, pitch adjustment elements 33, and an adjustment shaft 34. The connecting rib 31 is mounted on the vertical adjustment module 2. The pitch adjustment plate 32 is connected to the connecting rib 31 via the pitch adjustment elements 33 and the adjustment shaft 34. Two pitch adjustment elements 33 are provided, located on either side of the adjustment shaft 34, and adjust the tilt angle of the pitch adjustment plate with the adjustment shaft 34 as the axis. This embodiment achieves high-precision and flexible adjustment with multiple degrees of freedom. Through the cascaded layout of the vertical, pitch, and horizontal adjustment modules 4, the camera's spatial pose can be independently adjusted in multiple axes, achieving precise and stable control of the shooting angle and effectively meeting the diverse requirements for camera angle and position in complex scenarios. The pitch adjustment module 3 adopts a combination structure of adjustment elements and rotating shafts with a symmetrical layout on both sides, greatly improving the accuracy and stability of angle control. Two pitch adjustment elements 33 are distributed on both sides of the rotating shaft, which can work together to achieve fine-tuning and reliable locking of the pitch angle, effectively preventing structural deformation or displacement deviation caused by uneven force on one side, ensuring that the camera maintains extremely high attitude stability after adjustment in the pitch direction, suitable for high-resolution imaging requirements. The overall structure of this embodiment is compact and rigid, and the connection between each module is reasonable, ensuring the realization of multi-directional adjustment functions while minimizing vibration and shaking, which is conducive to long-term stable operation. It is particularly suitable for fields such as machine vision, precision measurement, and optical inspection, and can significantly improve image acquisition quality and system automation level, with good engineering application value.

[0024] The vertical adjustment module 2 includes a vertical fixing block 21, a vertical adjustment plate 22, and a vertical adjustment element 23. The vertical adjustment plate 22 is mounted on the base plate 1, the vertical fixing block 21 is located on one side of the vertical adjustment plate 22, and the vertical adjustment element 23 is mounted on the vertical fixing block 21 and connected to the vertical adjustment element 23. The vertical adjustment element 23 is used to drive the vertical adjustment plate 22 to slide. Specifically, two connecting ribs 31 are provided, and the two connecting ribs 31 are respectively located on both sides of the vertical adjustment plate 22. The pitch adjustment plate 32 is located above the connecting ribs 31 to form a frame groove, and the camera module 5 is located in the frame groove. The pitch adjustment element 33 includes a pitch connecting block 331 and a pitch adjustment screw 332. The connecting rib 31 is provided with an assembly groove, the pitch connecting block 331 is mounted on the assembly groove, and the pitch adjustment screw 332 is used to connect the pitch adjustment plate 32 to the pitch connecting block 331. In this embodiment, the vertical adjustment module 2, through the cooperation of the vertical fixing block 21, the vertical adjustment plate 22, and the vertical adjustment element 23, achieves precise linear displacement of the camera in the vertical direction. The vertical adjustment element 23 drives the vertical adjustment plate 22 to slide smoothly along the base plate 1. The structure is simple and the transmission is direct, effectively avoiding the error accumulation and backlash caused by multi-stage transmission, ensuring the repeatability and positioning reliability of the adjustment, and is suitable for scenarios requiring fine adjustment such as focusing or height compensation. The connecting stiffener 31 is symmetrically arranged on both sides of the vertical adjustment plate 22, and together with the pitch adjustment plate 32 above, forms a frame groove structure to accommodate the camera module 5 inside. This enhances the rigidity of the overall mechanism, resists deformation caused by adjustment or external vibration, and provides multi-directional enveloping support for the camera, improving stability during movement, especially suitable for long exposure or high-resolution imaging, effectively reducing image blur. In the pitch adjustment module 3, the pitch connecting block 331 is embedded in the mounting groove of the connecting stiffener 31, and is connected to the pitch adjustment plate 32 by the pitch adjustment screw 332. This design ensures the assembly precision and relative positional stability of the parts, and leverages the fine-tuning characteristics of the threaded joints to achieve delicate and controllable adjustment of the pitch angle using conventional tools. Two pitch adjustment elements are positioned on either side of the rotating shaft, allowing for precise control of the pitch angle through symmetrical screwing. This avoids skewness or jamming caused by single-point force, while also improving angle symmetry and adjustment repeatability, meeting the stringent requirements of optical systems for attitude consistency.

[0025] A first arc-shaped groove 311 is provided on the connecting stiffener 31, and a second arc-shaped groove 321 is provided on the pitch adjustment plate 32. The first arc-shaped groove 311 and the second arc-shaped groove 321 are opposite to each other, forming a stroke adjustment arc-shaped groove. The adjustment shaft 34 is disposed on the adjustment arc-shaped groove. In this embodiment, the arc-shaped groove forms a circumferential constraint on the adjustment shaft 34, providing a stable motion trajectory and a reliable rotation center for the shaft during pitch angle adjustment. This effectively prevents the shaft from shifting or loosening under stress, improving the structural rigidity and motion accuracy of the pitch adjustment. The cooperation between the arc-shaped groove and the shaft has a self-centering characteristic, which helps to reduce assembly errors and enhance the repeatability and consistency of angle adjustment. This arc-shaped groove structure achieves a wide range of pitch angle adjustment capabilities within a limited space. Its arc-shaped direction naturally matches the pitch movement, expanding the angle adjustment range while ensuring a compact overall structure with no additional space occupation, making it particularly suitable for equipment integration applications sensitive to installation space. The mating surfaces of the arc groove and the rotating shaft can be precision machined and lubricated to further reduce motion friction and wear, extend service life, and suppress vibration and abnormal noise during adjustment, which helps maintain the imaging stability of the camera after dynamic adjustment.

[0026] The upper surface of the pitch adjustment plate 32 is provided with an adjustment platform 322. The horizontal adjustment module 4 includes a horizontal adjustment plate 41 and a horizontal adjustment element 42. The horizontal adjustment plate 41 is disposed on the adjustment platform 322, and the horizontal adjustment element 42 is used to adjust the movement of the horizontal adjustment plate 41 on the adjustment platform 322. Specifically, a fixed step 323 is provided on one side of the adjustment platform 322. The horizontal adjustment element 42 is disposed on the fixed step 323 and connected to the horizontal adjustment plate 41 to adjust the movement of the horizontal adjustment plate 41 on the adjustment platform 322. In this embodiment, the horizontal adjustment module 4 adopts a platform layout, which is compact and has a clear force transmission path. The horizontal adjustment plate 41 directly supports the camera module 5 and achieves smooth movement on the adjustment platform 322 through the horizontal adjustment element 42, thus completing the horizontal position adjustment. This avoids multi-stage transmission, effectively reduces the error accumulation and idle phenomenon caused by intermediate links, improves the accuracy and response consistency of horizontal adjustment, and meets the stringent requirements for fine-tuning of lateral position in high-resolution imaging. A fixed step 323 is provided on one side of the adjustment platform 322. The horizontal adjustment element 42 is mounted on the fixed step 323 and connected to the horizontal adjustment plate 41. Utilizing the upper surface space of the pitch adjustment plate 32, the horizontal adjustment mechanism achieves an integrated and modular layout, saving both the longitudinal and lateral dimensions of the overall structure and enhancing its rigidity. The fixed step 323 provides a stable and reliable mounting base for the horizontal adjustment element 42, ensuring that its force direction is consistent with the movement direction of the horizontal adjustment plate 41, thus guaranteeing transmission efficiency and adjustment stability. The horizontal adjustment element 42 (such as an adjustment screw or a miniature drive component) can drive the horizontal adjustment plate 41 for precise displacement via a threaded pair or precision guide rail mechanism. Users can achieve precise control and reliable locking of the camera's horizontal position through simple operation, making it particularly suitable for applications such as vision alignment, image stitching, and multi-camera synchronization, effectively improving the system's automation level and operational convenience.

[0027] The camera module 5 includes a camera assembly 51, a heat dissipation assembly 52, and a lens 53. The lens 53 is mounted on the camera assembly 51, and the heat dissipation assembly 52 is located at the upper end of the camera assembly 51 for heat dissipation. The camera assembly 51 is mounted on the horizontal adjustment element 42. Specifically, the camera assembly 51 is provided with a camera mounting base 511, which is used to fix the camera assembly 51 to the horizontal adjustment module 4. The heat dissipation assembly 52 includes heat dissipation fins 521 and a cooling fan 522 mounted on the camera assembly 51, which is used to dissipate heat from the heat dissipation fins 521. In this embodiment, the camera assembly 51 is reliably connected to the horizontal adjustment plate 41 through the camera mounting base 511, ensuring that the camera module 5 maintains a stable mechanical fixed state during multi-degree-of-freedom adjustment in three-dimensional space. This rigid connection effectively suppresses relative displacement or loosening caused by adjustment actions or external vibrations, ensuring the consistency of the optical center position and the controllability of the posture. This is beneficial for maintaining image clarity and coordinate accuracy, and is especially suitable for high-precision visual measurement and positioning applications. The heat dissipation component 52, through the combined action of the heat dissipation fins 521 and the cooling fan 522 located on the upper end of the camera component 51, achieves efficient thermal management. The camera component 51 (especially the image sensor and main control chip) is prone to generating a large amount of heat during long-term operation. Overheating can lead to increased noise, color drift, and even device damage. The heat dissipation fins 521 increase the heat dissipation area and accelerate the diffusion of heat into the air; the cooling fan 522 actively generates airflow, enhancing the forced convection effect and significantly improving overall heat dissipation efficiency. This effectively controls the operating temperature of the camera module 5, ensuring the stability of image quality and the reliability of equipment operation, and extending the camera's lifespan.

[0028] Furthermore, concentrating the heat dissipation component 52 on the upper part of the camera component 51 not only makes full use of the unused space above the module but also avoids interference of the heat dissipation structure with other adjustment mechanisms (such as pitch or horizontal movement), demonstrating high space utilization and structural integration. At the same time, the cooling fan 522 and the heat dissipation fins 521 can be flexibly selected according to the actual power consumption, exhibiting good adaptability and expandability.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
