Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer vision inspection technology, specifically to a computer vision inspection auxiliary device. Background Technology
[0002] Computer vision is a simulation of biological vision using computers and related equipment. Its main task is to process acquired images or videos to obtain three-dimensional information of the corresponding scene. Simply put, it uses machines to replace human eyes for measurement and judgment. Through computers, the detected product (i.e., image acquisition device, which is divided into CMOS and CCD) can be converted into image signals of the captured target, and then the on-site equipment actions can be controlled according to the judgment results. It is valuable for production, assembly or packaging.
[0003] The reference patent number is "CN217843239U", entitled "A Computer Vision Inspection Auxiliary Device". Although this application solves the problem that "when performing computer vision inspection, it is necessary to adjust the height of the camera. Currently, conventional brackets are mostly used, but ordinary brackets can only provide simple support and cannot adjust the support height or the adjustment support is not stable enough, affecting normal video recording. Moreover, the camera is cumbersome to disassemble and assemble, has poor installation stability, and is very inconvenient to use. In addition, the camera is often exposed to the air, and when the camera is not in use, it is easily affected by external interference, and the camera surface is easily damaged and dust easily adheres to the camera surface." However, it also has some drawbacks. For example, the moving wheels and wheel frame are connected movably and lack shock absorption design. Bumps during movement may be transmitted to the camera, causing image jitter. Secondly, the camera's raising and lowering is driven by manually rotating the handle to drive the second threaded shaft. In scenarios where the camera needs to be used frequently (such as assembly line inspection), manual operation is inefficient and prone to misoperation. Therefore, a computer vision inspection auxiliary device is proposed to solve the above-mentioned technical problems. Utility Model Content

[0016] Compared with the prior art, the present invention provides a computer vision detection auxiliary device, which has the following beneficial effects:
[0017] 1. This computer vision inspection auxiliary device integrates a shock-absorbing moving component at the bottom of the base, constructing a three-level vibration reduction system of "hydraulic damping + spring buffer + guide limit": the hydraulic damper provides a certain attenuation capability for high-frequency vibrations, and the external buffer spring absorbs a certain amount of low-frequency impacts, reducing the vibration energy transmitted from the base to the camera. The precision guide structure of the limit rod and the lead screw shaft controls the lateral displacement of the bearing plate within a small range, avoiding posture deviation during movement, effectively solving the problem of image jitter caused by road bumps, and improving the practicality of the device.
[0018] 2. This computer vision inspection auxiliary device, through the setting of a drive component, starts a micro servo motor to drive the second bevel gear to rotate via the output shaft. The meshing transmission between the second bevel gear and the first bevel gear causes the threaded rod to rotate, driving two threaded blocks to move in opposite directions. Then, through the cooperation of the threaded blocks, the X-shaped connecting rod and the two sliders, the fixed plate moves the camera down into the protective box for protection. In use, the micro servo motor is driven to rotate in the opposite direction, eliminating the need for manual rotation of the handle. This improves operational efficiency, avoids misoperation, reduces the labor intensity of the staff, and further enhances the practicality of the device. Attached Figure Description
