Camera Detailed Implementation
[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0027] like Figure 1 and Figure 2 As shown, an inspection data acquisition device according to this application includes a camera pan-tilt unit 1, a fixed base 2, a rotating shaft 3, a dust cover 4, and a buffer gasket 5. These components work together to achieve automated and stable inspection task execution.
[0028] The camera pan-tilt head 1 is a crucial component of the entire device, used to support and mount the camera 18 and drive it to perform tilt movements. The camera pan-tilt head 1 includes a circular limiting groove 11, which mechanically restricts the rotation range of the pan-tilt head, preventing the camera 18 from excessively rotating or deviating from a preset angle range. Simultaneously, a first servo motor 12 is installed within this groove. This servo motor outputs high-precision angle control actions and drives the camera 18 to rotate via a connected support shaft 17, thereby enabling the camera 18 to automatically adjust its tilt angle. To ensure the stability of the data cable during use, the camera pan-tilt head 1 is equipped with an arc-shaped cable guide tube 13, which guides the cable from one end to the other, forming a suitable curved path, effectively preventing unnecessary tangling of the cable as the device rotates. Specifically, the first servo motor 12 can be a brushless DC servo type, paired with an incremental or absolute photoelectric encoder to achieve precise position feedback. The cable guide tube can be made of a flexible insulating material, such as modified plastic.
[0029] The fixed base 2 serves as the foundation support and interface connector in the overall structure. It has a platform of a certain thickness and width to ensure the rigidity and vibration resistance of the overall structure. Its design incorporates several mounting interfaces 15, which are mainly used for secure assembly with external handheld mechanisms or other mobile platforms, allowing the camera pan-tilt unit 1 to move with the external device for more comprehensive and flexible inspection. In actual operation, the fixed base 2 can be made of aluminum alloy to provide necessary stability and lightweight design, while also ensuring convenient installation with external facilities such as handheld devices.
[0030] The rotating shaft 3, acting as an intermediate force transmission component, plays a crucial role in connecting the camera gimbal 1 and the fixed base 2 for rotational movement. Its simple yet vital structure transmits the torque driven by the servo motor during operation, ensuring the gimbal operates smoothly and stably according to commands. This component must be manufactured using high-hardness alloy materials to ensure durability over extended periods and to operate normally under various torque and speed requirements.
[0031] The dust cover 4 is arranged around the area through which the rotating shaft 3 passes. Its main function is to provide effective protection and shielding for the internal mechanical parts. Since the working environment may be full of dust and particulate matter, installing the dust cover 4 can effectively prevent these external contaminants from entering sensitive internal parts and causing wear or jamming. From a manufacturing perspective, the dust cover 4 is generally made of elastic silicone or other thermoplastic elastomer materials, and it also needs to be molded using a specific mold to ensure a tight fit with the bearing shaft 17 without any gaps.
[0032] The buffer washer 5 is placed between the end of the rotating shaft 3 and the fixed base 2. This component mainly serves to reduce vibration and noise during operation and extend the service life of related mechanical parts. In practice, the buffer washer 5 is custom-cut from special rubber or composite non-metallic materials, utilizing its elastic properties and friction resistance adjustment effect to achieve the optimal vibration reduction target.
[0033] To address the technical challenge of cable entanglement, this device cleverly utilizes the design features of the arc-shaped cable guide tube 13. Traditional methods of straight cable pulling or simple fixing often cannot avoid the problems of knotting and compression damage caused by repeated rotation. However, the application of the arc-shaped cable guide tube 13 ensures that the cable maintains a certain amount of space during entry and exit, always remaining within a reasonable bending radius. Therefore, even after the camera pan-tilt unit 1 has continuously performed multiple pitch and directional changes, the internal wiring remains orderly and unaffected. This not only improves reliability but also significantly reduces maintenance frequency, further enhancing the practicality of the equipment.
[0034] like Figure 3 and Figure 4 As shown, in one embodiment, the dust cover 4 of the inspection and data acquisition device of this application has a specific structure on its exterior to enable intuitive reading of the pitch angle range. Specifically, a disc-shaped component is added to the outer wall of the dust cover 4. This component is rotatable and maintains a tight fit with the dust cover 4. A bearing shaft 17 is located inside, and an indicator component is fixed at a position corresponding to the disc-shaped component. This indicator component can dynamically point to the markings on the disc-shaped component as the bearing shaft 17 rotates. This combination clearly shows the actual rotation range of the camera 18 during pitch movement through visual display.
[0035] For example, during the production process, a circular angle disk 6 with evenly graduated lines can be precisely installed on the outer wall of the dust cover 4 using machining methods. Special tooling is then used to ensure that the pointer 7 on the support shaft 17 is aligned with the angle disk 6 and maintains a perpendicular relationship. In this structure, when the support shaft 17 rotates due to the drive of the first servo motor 12, the pointer 7 deflects accordingly, thus pointing to the corresponding angle value range in real time. This design effectively combines mechanical positioning and angle calibration functions, further enhancing the ease of operation and visualization capabilities.
[0036] like Figure 6 As shown, in one embodiment, the arc-shaped cable guide tube 13 of the inspection and acquisition device of this application is made of a flexible conductive material. The properties of this material allow it to reduce interference with electromagnetic signals while maintaining flexibility, ensuring stable transmission of electrical signals within the acquisition device. The arc-shaped cable guide tube 13 connects the fixed base 2 and the camera pan-tilt unit 1, and is arranged around the outside of the rotating shaft 3, thus not affecting the transmission of rotational motion by the rotating shaft 3 and the vibration reduction function of the buffer washer 5. Furthermore, the arc-shaped cable guide tube 13 is also provided with a separator strip 8 structure. By embedding the separator strip 8, multiple independent channel spaces are formed, preventing the entanglement of multiple cables due to prolonged use.
[0037] For example, the arc-shaped cable guide tube 13 can be made of flexible copper alloy as the conductive material, and a flexible insulating separator 8 can be used inside to achieve a separation design. Specifically, during manufacturing, the separator 8 can be injection molded into the inner wall of the cable guide tube to form multiple evenly distributed independent channels, ensuring that each cable has its own dedicated path, while retaining the overall flexibility to facilitate installation and adapt to slight deformations that may occur during device operation. In this way, not only can the stable operation of the equipment be guaranteed, but the rationality of the internal structural layout of the device is further optimized.
[0038] like Figure 5As shown, in one embodiment, the inspection and data acquisition device of this application is characterized by an improvement to the fixed base 2, enabling it to more accurately ensure the installation precision and operational stability of the rotating shaft 3. Specifically, a specific hole-like structure, namely a central positioning hole 9, is provided at the center of the fixed base 2. The main function of this central positioning hole 9 is to provide a clear geometric reference point to achieve precise alignment between the rotating shaft 3 and the fixed base 2 during installation. This design can effectively improve the overall operational reliability of the device, especially in applications requiring high rotational precision.
[0039] The center positioning hole 9 is positioned in the central area of the fixed base 2, and its shape is strictly adapted to the outer contour of the rotating shaft 3. To ensure that the coaxiality requirements are met, the design parameters of the hole (e.g., the hole diameter) must be controlled within strict tolerance ranges during the machining process. This hole positioning guides the process, ensuring that deviations are minimized during the insertion and assembly of the rotating shaft 3, and avoiding potential wear or vibration problems caused by misalignment during operation.
[0040] For example, precision drilling can be performed using a CNC machine tool during the machining stage of the fixed base 2, and the actual position and shape of the center positioning hole 9 can be verified with testing instruments to ensure it meets design requirements. Furthermore, during installation, a fixture can be used to pre-align the rotating shaft 3 with the fixed base 2, and this hole can then be used as a basis for further fine-tuning. The connection between the buffer washer 5 and the rotating shaft 3 and fixed base 2 also relies on the center positioning hole 9 to optimize coaxiality.
[0041] like Figure 1 As shown, in one embodiment, an operation panel 10 is installed on the fixed base 2 of the inspection and data acquisition device of this application. The operation panel 10 is installed on one side wall of the fixed base 2 and can be connected to the control system of the camera pan-tilt unit 1 via wired or wireless means, thereby realizing the control and adjustment of the angle of the camera 18. This design allows operators to directly adjust the direction and tilt angle of the camera 18, further optimizing the user experience during the inspection process. By arranging the operation panel 10 on a specific side of the fixed base 2, it is integrated into the overall structure while retaining sufficient operating space, ensuring a reasonable layout of the whole machine and convenient human-computer interaction.
[0042] For example, the operation panel 10 can be connected to the first servo motor 12 and control circuit inside the camera pan-tilt unit 1 via an embedded interface, thereby sending commands to control the motor rotation. Specifically, the operation panel 10 may include multiple input components such as buttons, touch screens, or knobs, and combine with an internal control chip to complete signal conversion. These signals are transmitted to the first servo motor 12 drive module according to a preset protocol to precisely adjust the attitude and direction of the camera 18, thereby adapting to different inspection needs.
[0043] like Figure 5 As shown, in one embodiment, a second servo motor 14 is installed at one end of the rotating shaft 3 of the inspection and acquisition device of this application. This motor, through a specific installation position and structural connection design, enables automatic adjustment of the angle of the camera pan-tilt unit 1. Specifically, the second servo motor 14 is fixed in a corresponding area inside the device and directly connected to one end of the rotating shaft 3. Its function is to provide the camera pan-tilt unit 1 with a rotational driving force around the axial direction, enabling the camera assembly to perform omnidirectional adjustment within a preset range in the horizontal direction. Through the precise angle control characteristics of the servo motor, the camera pan-tilt unit 1 can achieve multi-angle switching according to actual needs. This design fully utilizes the rigid transmission relationship between the second servo motor 14 and the rotating shaft 3, maintaining operational stability while meeting the requirements for perspective changes in complex scenarios.
[0044] For example, suitable space can be reserved in the fixed base 2 of the device to install the second servo motor 14, and the output end of the motor can be firmly connected to the rotating shaft 3 via a coupling. Simultaneously, a corresponding signal processing module needs to be set up in the electronic control system to receive externally input control commands and transmit accurate motion parameters to the second servo motor 14 through the drive circuit. In this way, the camera pan-tilt unit 1 can be easily driven to adjust its angle along the axial direction by the forward and reverse operation of the servo motor, ensuring that the acquisition process meets automation requirements.
[0045] like Figure 4 As shown, in one embodiment, a dust cover 4 of the inspection and data collection device of this application covers the outside of the bearing shaft 17 to effectively protect the internal parts. Specifically, the dust cover 4 is designed to reduce the impact of dust and impurities in the external environment on the rotating parts and connecting areas of the bearing shaft 17, ensuring stable operation of the device over a long period of time. To further improve its protective performance, an annular sealing structure is provided inside the dust cover 4. This structure fits tightly between the inner wall of the dust cover 4 and the bearing shaft 17, optimizing the contact effect between the two and forming a more rigorous sealing environment.
[0046] The aforementioned annular sealing structure can be made of a soft and elastic material, such as silicone or fluororubber, thus ensuring durability while providing a certain degree of elasticity for assembly. For example, the annular sealing structure is fixed in a pre-set annular groove inside the dust cover 4 by press-fitting, and then fitted onto the bearing shaft 17. This method achieves a tight fit between the two and effectively prevents dust particles from entering. Specifically, during the actual assembly process, the positional accuracy of the annular sealing structure must be ensured so that the bearing shaft 17 can obtain reliable sealing protection without adding extra resistance.
[0047] like Figure 4As shown in one embodiment, one of the key designs of the inspection and data collection device of this application lies in the selection and installation method of the sealing components to adapt to temperature changes in complex environments. The annular sealing ring 16, as an important dustproof and waterproof component, is carefully installed between the rotating shaft 3 and the dust cover 4, serving to prevent external dust and moisture from entering the internal space. To meet the operational requirements under different temperature conditions, the annular sealing ring 16 is made of silicone rubber, a material chosen for its good elasticity, resistance to high and low temperatures, and aging resistance. By applying a certain amount of pre-compression during installation, the connection loosening problem caused by differences in the thermal expansion coefficients of the components can be effectively compensated, ensuring the reliability of the device during long-term use.
[0048] Specifically, the technical implementation of the aforementioned pre-compression amount includes selecting a suitable inner diameter of the sealing ring after accurately measuring the assembly dimensions of the rotating shaft 3 and the dust cover 4, while controlling the compression rate of the sealing ring during installation to be between 5% and 10%. For example, by improving the assembly tools, it is ensured that the annular sealing ring 16 is fixed in place with a specific pressure in its initial state, thereby maintaining its sealing characteristics throughout the entire operation.
[0049] In actual operation, the camera 18 can be mounted on the camera pan-tilt unit 1, and the rotation range can be limited by the circular limiting groove 11. Then, the first servo motor 12 is started to drive the bearing shaft 17 to rotate, thereby realizing the tilt angle adjustment of the camera 18. At the same time, the arc-shaped cable guide tube 13 effectively avoids the cable tangling caused by movement. By connecting the external handheld mechanism to the mounting interface 15, the entire device can be moved for inspection. The rotating shaft 3 is responsible for transmitting the support force from the fixed base 2 and the rotational force during movement, ensuring the stable operation of the camera pan-tilt unit 1. During this process, the dust cover 4 covers the bearing shaft 17, playing a key role in preventing dust intrusion, while the buffer gasket 5 reduces the vibration between the rotating shaft 3 and the fixed base 2 during operation, ensuring the stability and accuracy of the device operation.
