Description

Technical Field

[0001] This utility model relates to the field of optical flow ranging technology, and in particular to an optical flow ranging device that is adaptable to multiple scenarios. Background Technology

[0002] With the rapid development of industrial automation, intelligent robots, and precision testing, optical flow ranging technology, due to its advantages such as non-contact measurement, fast response speed, and high ranging accuracy, has been widely used in scenarios such as equipment positioning, obstacle detection, and motion trajectory tracking, becoming a key sensing component in many automation systems. However, existing optical flow ranging devices have significant defects in their fixing methods, generally exhibiting a "single" characteristic, making it difficult to meet the diverse installation needs in practical applications. Most devices only support a single fixing mode, or rely solely on bolt fixing (requiring pre-set matching mounting holes), or only use suction cup adsorption (limited to adsorbable surfaces such as metal), failing to simultaneously accommodate multiple common installation scenarios such as "adsorbable equipment surfaces," "devices with pre-set mounting holes," and "devices with a central base," creating a mismatch between technological applications and actual needs. In complex application environments such as industrial sites, the problem of a single mounting method is particularly prominent. For example, in industrial robot workstations, some robotic arm shells are made of adsorbable metal materials, some detection platforms only have pre-drilled standardized mounting holes, and some rotary drive mechanisms use a circular base structure. Faced with these different types of mounting carriers, existing optical flow ranging devices need to frequently replace special mounting accessories (such as replacing the suction cup base or adding a clamping bracket) to achieve installation. This not only increases equipment procurement costs and inventory pressure, but also requires additional time for disassembling and debugging accessories, which seriously affects on-site operation efficiency.

[0003] Therefore, it is necessary to provide a new optical flow ranging device that is adaptable to multiple scenarios to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an optical flow ranging device that is adaptable to multiple scenarios.

[0005] The optical flow ranging device adapted to multiple scenarios provided by this utility model includes: a base, a moving rod, a telescopic structure, and a limiting structure. The top of the base is fixedly connected to the optical flow ranging device body, and the bottom of the base is fixedly connected to a magnetic suction cup. Moving rods are equidistantly arranged inside the base. Rotating blocks are rotatably connected to the mutually distant ends of the moving rods. Mounting holes are opened inside the rotating blocks. A telescopic structure is provided between the base and the moving rods, and a limiting structure is provided between the moving rods and the rotating blocks.

[0006] Preferably, the telescopic structure includes: a turntable and a flat thread. The turntable rotates inside the base. A fixed plate is fixedly connected to the side of the turntable away from the moving rod. A bevel gear ring is fixedly connected to the end of the fixed plate near the turntable. A rotating shaft is fixedly rotatably connected inside the base. A driving bevel gear is fixedly connected to the end of the rotating shaft near the fixed plate. The driving bevel gear meshes with the bevel gear ring. A flat thread is fixedly connected to the side of the turntable away from the fixed plate. A mating groove is opened at one end of the moving rod. The mating groove is installed in conjunction with the flat thread.

[0007] Preferably, the limiting structure includes: a square rod, a square groove, and a square through hole. The end of the moving rod near the rotating block has a groove, and a spring is fixedly connected inside the groove. One end of the spring is fixedly connected to a moving plate, which is slidably connected to the groove. The end of the moving plate away from the spring is fixedly connected to a square rod. One side of the moving rod has a square groove, which communicates with the groove. One end of the rotating block has a square through hole, and the square rod is inserted into the square groove and the square through hole respectively.

[0008] Preferably, one end of the square rod is fixedly connected to a top rod, and one end of the top rod extends out of one end of the movable rod.

[0009] Preferably, the mounting holes are used to mate with bolts for installation.

[0010] Preferably, the moving rod and rotating block are in a straight line in one state and in an L-shape in another state.

[0011] Compared with related technologies, the multi-scenario adaptable optical flow ranging device provided by this utility model has the following beneficial effects: The device integrates three installation methods: magnetic suction cup adsorption, bolt fixing, and L-shaped clamping. It can be adapted to various scenarios, including surfaces that can be adsorbed, devices with pre-set mounting holes, and circular base structures, without requiring replacement parts. Compared to traditional optical flow ranging devices with a single fixing method, it can be directly applied to different carriers such as industrial robots, inspection platforms, and rotating mechanisms, significantly improving the device's environmental adaptability and reducing the procurement and replacement costs of dedicated fixing parts.

[0012] The telescopic adjustment is synchronized and precise, resulting in high installation efficiency. The telescopic structure, through the synergistic action of a bevel gear ring and a flat thread, allows all moving rods to extend and retract synchronously with just a single rotating shaft, ensuring consistent extension lengths across all rods. This design solves problems such as rod misalignment and difficulty in hole alignment that often occur during adjustment in traditional devices, reducing the operation time for mounting hole alignment or clamping positioning by more than 50%, significantly improving installation and debugging efficiency.

[0013] The system features stable and reliable state switching and convenient operation. The limit structure utilizes a spring-driven square rod insertion design, allowing for quick release of the limit by pressing the top rod. The rotating block can flexibly switch between a straight or L-shaped position, automatically locking upon release without the need for tools. Compared to traditional snap-fit ​​or friction-type limiters, this structure offers higher locking strength, effectively resisting vibration or external impacts, preventing loosening, and simplifying operation while enhancing the convenience of rapid on-site adjustments.

[0014] Excellent installation stability ensures ranging accuracy. The magnetic chuck provides stable adsorption force, bolt fixing ensures uniform force through synchronous extension and retraction, and L-shaped clamping achieves symmetrical clamping through the synchronous approach of multiple rods. All three methods guarantee no offset after installation. The stable installation benchmark directly reduces ranging errors caused by equipment shaking or displacement, improving the reliability of measurement data from the optical flow ranging device, making it particularly suitable for high-precision detection scenarios.

[0022] The working principle of the multi-scenario adaptable optical flow ranging device provided by this utility model is as follows: I. Overall Structure and Core Components of the Device The device uses a base 1 as its basic carrier, with the optical flow ranging device body 2 fixed at the top to achieve the core ranging function, and a magnetic suction cup 3 fixed at the bottom to provide a foundation for adsorption and installation. Several movable rods 4 are evenly distributed inside the base 1. The end of the movable rod 4 away from the center of the base is rotatably connected to a rotating block 5. The rotating block 5 has mounting holes 6 for bolt fixing. The base 1 and the movable rods 4 are connected by a telescopic structure to achieve synchronous extension and retraction adjustment of the movable rods. The movable rods 4 and the rotating block 5 are connected by a limiting structure to achieve stable switching between "I-shaped" and "L-shaped" states. All structures work together to meet the installation needs of multiple scenarios.

[0023] II. Specific Working Principles and Scenario Adaptation Process Installation and working process of an adsorption device surface When the mounting medium is a metal or other absorbent material, quick fixation can be achieved directly using the magnetic chuck 3: Adsorption and fixation: The magnetic chuck 3 at the bottom of the base 1 is attached to the surface of the adsorbable device. The magnetic chuck 3 is tightly adsorbed to the surface of the carrier by magnetic force, thereby stably fixing the base 1 and the optical flow ranging device body 2. Distance measurement start-up: After adsorption is completed, the optical flow distance measuring device body 2 can enter the working state without additional adjustment. The adsorption force of the magnetic chuck 3 can resist slight vibration, ensure the stability of the distance measurement reference, and ensure measurement accuracy.

[0024] Installation and Workflow of Equipment with Two Mounting Holes When the mounting carrier has pre-drilled mounting holes, the position of the moving rod is adjusted via the telescopic structure, which, in conjunction with the mounting holes of the rotating block, enables bolt fixing. Initial state preparation: The moving rod 4 and the rotating block 5 are locked in a "one-line" state with the limit structure locked, and the mounting hole 6 of the rotating block 5 faces outward to facilitate alignment with the carrier mounting hole; Telescopic structure drive adjustment: The operator rotates the shaft 10 extending outside the base 1, which is fixedly connected to the drive bevel gear 11. The drive bevel gear 11 rotates accordingly and drives the bevel gear ring 9 meshing with it to rotate. The bevel gear ring 9 is fixed on the fixed disk 8, and the fixed disk 8 is rigidly connected to the turntable 7, so the turntable 7 rotates synchronously with the bevel gear ring 9; The turntable 7 has a flat thread 12 on the side near the moving rod 4, and the moving rod 4 has a mating groove 13 at the end near the turntable 7. The flat thread 12 meshes with the mating groove 13. When the turntable 7 rotates, the flat thread 12 generates a radial thrust on the moving rod 4 through the meshing action, causing several moving rods 4 to slide synchronously away from the center of the base until the mounting hole 6 of the rotating block 5 is aligned with the preset mounting hole of the carrier. Bolt fixing: Pass the bolts through the mounting holes 6 of the rotating block 5 and the carrier mounting holes and tighten them to fix the device. Then the optical flow ranging device body 2 starts working.

[0025] Clamping, Installation, and Workflow of the Three-Circle Base Equipment When the mounting carrier is a circular base structure, the state of the moving rod and the rotating block is switched by the limiting structure, and then the telescopic structure is used to drive the clamping and fixing: The limit structure operation is switched to the L-shaped state: In the initial state, under the elastic force of the spring 15, the square rod 17 is simultaneously inserted into the square groove 18 of the moving rod 4 and the square through hole 19 of the rotating block 5, restricting the rotation of the rotating block 5 to maintain a straight line shape. The pressing rod 20 is fixedly connected to the square rod 17. The pressing rod 20 drives the square rod 17 to move into the groove 14. The moving plate 16 compresses the spring 15 until the square rod 17 completely exits the square through hole 19 of the rotating block 5 and the limit is released. Rotate the rotating block 5 90° around its rotation connection point with the moving rod 4 so that the moving rod 4 and the rotating block 5 form an "L" shape. The rotating block 5 is perpendicular to the moving rod 4. At this time, another set of square through holes 19 on the rotating block 5 are aligned with the square groove 18 of the moving rod 4. Release the top rod 20, the spring 15 returns to its original position and pushes the moving plate 16 and the square rod 17 to pop out. The square rod 17 is re-inserted into the square groove 18 and the corresponding square through hole 19, locking the L-shaped state. Telescopic structure driven clamping: When the shaft 10 rotates in the opposite direction, the driving bevel gear 11, bevel gear ring 9, fixed disk 8 and turntable 7 rotate synchronously in the opposite direction. The planar thread 12 generates radial tension on the moving rod 4 through the mating groove 13. Several L-shaped moving rods 4 slide synchronously towards the center of the base. The inner wall of the rotating block 5 gradually fits against the outer wall of the central base until a stable clamping is formed. Distance measurement: After clamping and fixing, the optical flow ranging device body 2 is in a stable state. After starting, it can achieve accurate distance measurement through optical flow algorithm. The clamping force ensures that the device does not deviate during the operation of the carrier.
