Description

Technical Field

[0001] This utility model relates to the field of obstacle avoidance detection technology, specifically an obstacle avoidance detection platform based on optical measurement. Background Technology

[0002] Optical obstacle avoidance is a technology that utilizes optical principles for obstacle detection and avoidance, offering high precision, high reliability, and real-time performance. Its working principle is primarily based on a Time-of-Flight (TOF) depth camera, which includes a light source, a sensor module, and a control processing module. The light source emits light signals, and the sensor module receives the reflected light signals from obstacles, converting them into electrical signals that are transmitted to the control processing module. The control processing module obtains the detection results based on the electrical signals and, combined with the speed information of the moving vehicle, determines the obstacle avoidance measures. Compared to other obstacle avoidance technologies, such as ultrasonic and infrared, optical obstacle avoidance technology offers higher precision, faster feedback speed, and stronger anti-interference capabilities, as well as a wider effective range. Before industrial robots leave the factory, obstacle avoidance system testing is required, and this testing is typically performed using a testing platform.

[0003] Most existing inspection stations use bolts to install obstacles, which makes it inconvenient to disassemble and replace obstacles, reducing the efficiency of obstacle replacement and thus affecting inspection efficiency. Utility Model Content

[0004] To address the problem of reduced efficiency in obstacle replacement caused by bolt-mounted installation, the purpose of this invention is to provide an obstacle avoidance detection platform based on optical measurement.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an obstacle avoidance detection platform based on optical measurement, comprising a detection platform and an obstacle, wherein the obstacle is located above the detection platform, and the detection platform is provided with side-by-side movable components, and a disassembly and assembly assembly is provided between the movable components and the obstacle; both ends of the detection platform are fixedly provided with ramps; the movable components include support plates, which are symmetrically distributed and fixedly installed on the detection platform; a threaded rod is rotatably installed on the opposite side of the support plate, and a movable block is threadedly fitted on the outer side of the threaded rod; a connecting rod is fixedly provided at the bottom end of the movable block, and the movable block is driven by the threaded rod. The moving block moves, which in turn moves the connecting rod, which in turn moves the obstacle. The position of the obstacle can be adjusted randomly, which facilitates the adjustment of the obstacle's position. A motor is fixedly installed on the outer side of the support plate. The end of the motor's output shaft movably passes through the support plate and is fixedly connected to one end of the threaded rod. The motor can provide power for the rotation of the threaded rod. Symmetrically distributed baffles are fixedly installed on the upper surface of the detection table. The baffles are located on the outer side of the support plate to prevent the industrial robot from falling. A guide rod is fixed between the support plates. One end of the guide rod movably passes through the moving block, which can keep the moving block moving stably.

[0006] Preferably, the assembly / disassembly component includes a mounting block, the bottom end of which is fixedly connected to the obstacle. The bottom end of the connecting rod has a mounting groove, and the mounting block is movably engaged within the mounting groove. The inner wall of the mounting groove has symmetrically distributed grooves, and a limiting block is slidably engaged within each groove. The outer side of the mounting block has symmetrically distributed limiting grooves, and the limiting block is engaged within each limiting groove. The mounting block of the obstacle is engaged into the mounting groove, and the limiting block is moved into the groove, aligning the limiting groove with the limiting block. The limiting block then resets its position. The limiting block is inserted into the limiting groove to fix the mounting block, thus avoiding the inconvenience of disassembly and replacement due to obstacles. A return spring is fixedly installed on the inner wall of the groove, and one end of the return spring is fixedly connected to one end of the limiting block. Raising the return spring can drive the limiting block to return to its original position through its elastic force. A fixing rod is fixedly installed on the inner wall of the groove, and one end of the fixing rod moves through the limiting block. The fixing rod can keep the limiting block moving stably. One end of the mounting block has symmetrically distributed inclined surfaces, which can squeeze the limiting block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. The mounting block of the obstacle is inserted into the mounting groove, and the spring force of the reset spring drives the limit block to reset, so that the limit block is inserted into the limit groove to fix the mounting block. This can avoid the inconvenience of disassembling and replacing the obstacle, thereby improving the disassembly and assembly efficiency.

[0009] 2. The moving block is driven by the threaded rod, which in turn drives the connecting rod, which in turn drives the obstacle to move. The position of the obstacle can be adjusted randomly, which makes it easy to adjust the position of the obstacle and thus improves the comprehensiveness of the detection.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-3As shown, this utility model provides an obstacle avoidance testing platform based on optical measurement, including a testing platform 1 and an obstacle 3. The obstacle 3 is located above the testing platform 1. Moving components 4 are arranged side-by-side on the testing platform 1, and a disassembly / assembly assembly 2 is provided between the moving components 4 and the obstacle 3. Slopes 5 are fixedly installed at both ends of the testing platform 1. The moving components 4 include support plates 41, which are symmetrically distributed and fixedly installed on the testing platform 1. A threaded rod 42 is rotatably installed on the opposite side of the support plate 41. A moving block 43 is threaded onto the outer side of the threaded rod 42. A connecting rod 44 is fixedly installed at the bottom end of the moving block 43. The moving block 43 is moved by the threaded rod 42, and the moving block 43 drives the movement of the moving block 43. The connecting rod 44 moves, causing the obstacle 3 to move and adjust its position. This allows for easy adjustment of the obstacle 3's position. A motor 45 is fixedly installed on the outer side of the support plate 41. The end of the output shaft of the motor 45 movably passes through the support plate 41 and is fixedly connected to one end of the threaded rod 42. The motor 45 provides power for the rotation of the threaded rod 42. Symmetrically distributed baffles 6 are fixedly installed on the upper surface of the detection table 1. The baffles 6 are located on the outer side of the support plate 41 to prevent the industrial robot from falling. A guide rod 46 is fixedly installed between the support plates 41. One end of the guide rod 46 movably passes through the moving block 43, which helps to keep the moving block 43 moving stably.

[0017] The assembly / disassembly component 2 includes a mounting block 21. The bottom end of the mounting block 21 is fixedly connected to the obstacle 3. The bottom end of the connecting rod 44 has a mounting groove 22. The mounting block 21 is movably engaged in the mounting groove 22. The inner wall of the mounting groove 22 has symmetrically distributed grooves 23. A limiting block 24 is slidably engaged inside the groove 23. The outer side of the mounting block 21 has symmetrically distributed limiting grooves 25. The limiting block 24 is engaged in the limiting groove 25. The mounting block 21 of the obstacle 3 is engaged in the mounting groove 22, and the limiting block 24 is moved into the groove 23. The limiting groove 25 and the limiting block 24 are aligned. The limiting block 24 is reset to its original position, thus aligning the limiting groove 25 with the limiting block 24. The positioning block 24 is inserted into the limiting groove 25 to fix the mounting block 21, thus avoiding the inconvenience of disassembling and replacing the obstacle 3. A return spring 26 is fixedly provided on the inner wall of the groove 23. One end of the return spring 26 is fixedly connected to one end of the limiting block 24. Raising the return spring 26 can drive the limiting block 24 to reset through the elastic force. A fixing rod 27 is fixedly provided on the inner wall of the groove 23. One end of the fixing rod 27 moves through the limiting block 24. The fixing rod 27 can keep the limiting block 24 moving stably. One end of the mounting block 21 has symmetrically distributed inclined surfaces 28. The inclined surfaces 28 can squeeze the limiting block 24.

[0018] Working principle: First, the mounting block 21, which is to be used as obstacle 3, is inserted into the mounting groove 22. The mounting block 21, through the pressing force of the inclined surface 28 on the limiting block 24, causes the limiting block 24 to move into the groove 23. The fixing rod 27 keeps the limiting block 24 moving stably. At the same time, the limiting block 24 compresses the return spring 26, causing the return spring 26 to generate elastic force. The limiting groove 25 aligns with the limiting block 24. The return spring 26, through its elastic force, drives the limiting block 24 to return to its original position, so that the limiting block 24 is inserted into the limiting groove 25 and fixes the mounting block 21. This avoids the inconvenience of assembling and disassembling obstacle 3. In the replacement scenario, motor 45 is then started, causing it to operate. The end of the output shaft of motor 45 drives the threaded rod 42 to rotate, which in turn drives the moving block 43 to move. The moving block 43 is kept stable by the guide rod 46. The moving block 43 drives the connecting rod 44 to move, which in turn drives the obstacle 3 to move, thus adjusting its position. This allows for easy adjustment of the obstacle 3's position. Then, the industrial robot moves onto the inspection platform 1 via the ramp 5. The industrial robot uses a depth camera to detect the obstacle 3 and obtains the results for obstacle avoidance testing.

[0019] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
