Description

Technical Field

[0001] This utility model relates to the field of self-calibration positioning device technology, and in particular to a self-calibration positioning device for an imaging detection system. Background Technology

[0002] Imaging detection systems typically include core components such as cameras (e.g., CCD or CMOS), lenses, light sources, and image processing software. These components work together to capture images of objects and analyze and judge them using image processing algorithms. Self-calibration positioning technology ensures that the system maintains high-precision detection and positioning under various environments and conditions by automatically adjusting the parameters of the imaging system, such as the camera's internal parameters (focal length, principal point, pixel size, etc.) and external parameters (position and orientation relative to the world coordinate system).

[0003] Self-calibration positioning technology is key to ensuring the accuracy and reliability of imaging detection systems. It automatically adjusts system parameters periodically or as needed to compensate for the impact of environmental changes, mechanical wear, and other factors on system performance.

[0004] Existing imaging inspection systems' self-calibration positioning devices cannot perform multi-angle and multi-distance calibration and positioning of products, resulting in a certain degree of randomness in product calibration and positioning, thus limiting the applicability of self-calibration positioning devices. Utility Model Content

[0005] The main purpose of this invention is to provide a self-calibration positioning device for an imaging detection system, which can effectively solve the problem of not being able to calibrate and position products from multiple angles and at different distances.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A self-calibration positioning device for an imaging detection system includes a base. A fixing component is fixedly connected to the upper end of the outer surface of the base. A bearing mechanism is fixedly connected to the middle of the fixing component. A photoelectric sensor is fixedly mounted on the upper outer side of the bearing mechanism. A motor is fixedly mounted on the middle of the bottom wall of the inner cavity of the base. A guide groove is formed in the middle of the bottom wall of the inner cavity of the base. A guide mechanism is rotatably connected to the inner cavity of the guide groove. A rotating component is fixedly connected to the upper outer side of the guide mechanism. A transmission mechanism is meshed with both the outer and inner sides of the rotating component. An imaging acquisition component is fixedly connected to the upper outer side of each of the two transmission mechanisms.

[0008] Preferably, the fixing assembly includes a plurality of cross-shaped fixing brackets, an outer annular plate is fixedly connected to the outer side of the lower end of the outer surface of the plurality of cross-shaped fixing brackets, an inner annular plate is fixedly connected to the middle of the lower end of the outer surface of the plurality of cross-shaped fixing brackets, and a carrying plate is fixedly connected to the inner side of the lower end of the outer surface of the plurality of cross-shaped fixing brackets.

[0009] Preferably, the guiding mechanism includes a fixed support plate, and an annular guide frame is fixedly connected to the lower end of the outer surface of the fixed support plate, and the lower end of the outer surface of the annular guide frame is rotatably connected to the inner cavity of the guide groove.

[0010] Preferably, the rotating assembly includes a connecting frame, an inner toothed ring is fixedly connected to the outer surface of the connecting frame, an outer toothed ring is fixedly connected to the inner surface of the connecting frame, and the lower end of the outer surface of the connecting frame is fixedly connected to the upper end of the outer surface of the fixed support plate.

[0011] Preferably, the transmission mechanism includes a limiting ring, and a transmission gear is rotatably connected to the middle of the upper end of the outer surface of the limiting ring.

[0012] Preferably, the imaging acquisition component includes a carrier frame, an imaging acquisition module is fixedly connected to the bottom wall of the inner cavity of the carrier frame, and a photosensitive CCD is mounted and fixed on the upper surface of the outer surface of the imaging acquisition module.

[0013] Preferably, the bearing mechanism includes a fixed frame, and a plurality of clamping plates are slidably connected in a circular array on the upper side inside the fixed frame. A limit plate is fixedly connected to the upper surface of the plurality of clamping plates, and the lower end of the outer surface of the fixed frame is fixedly connected to the middle part of the upper surface of the outer surface of the load plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model achieves a stable connection between the fixed component and the rotating component, supports the product through the bearing mechanism, and guides the movement of the rotating component through the guiding mechanism, thus improving the practicality of the device. The rotating component drives the two transmission mechanisms to rotate at a constant speed, which in turn drives the imaging acquisition component to rotate at a constant speed. Furthermore, the imaging acquisition component enables the product to perform self-calibration and positioning, thereby improving the practicality and versatility of the device.

[0016] 2. This utility model can drive the internal and external gear rings to rotate simultaneously via a drive motor. Since the circumferences of the gear rings of the internal and external gear rings are different, the movement trends of the two photosensitive CCDs are different. At the same time, since the distances of the two photosensitive CCDs from the product are different, the self-calibration positioning of the product can be made more accurate through the two photosensitive CCDs, thus improving the practicality and universality of the device.

The guide frame 52 can support the fixed support plate 51 and guide its movement at the same time. The lower end of the outer surface of the annular guide frame 52 is rotatably connected to the inner cavity of the guide groove 11.

[0026] To achieve the goal of driving the two transmission mechanisms 7 to rotate at a constant speed, refer to... Figure 3 The rotating component 6 includes a connecting frame 61, which can simultaneously drive the inner toothed ring 62 and the outer toothed ring 63 to rotate. The inner toothed ring 62 is fixedly connected to the outer surface of the connecting frame 61, and the outer toothed ring 63 is fixedly connected to the inner surface of the connecting frame 61. The lower end of the outer surface of the connecting frame 61 is fixedly connected to the upper end of the outer surface of the fixed support plate 51.

[0027] To achieve the goal of driving the imaging acquisition component 8 to rotate at a constant speed, refer to... Figure 3 The transmission mechanism 7 includes a limiting ring 71, which can connect to the transmission gear 72 and guide its movement. The transmission gear 72 is rotatably connected to the middle of the upper end of the outer surface of the limiting ring 71, which can mesh with the inner surface of the inner gear ring 62 or the outer surface of the outer gear ring 63 to rotate.

[0028] To achieve the purpose of product self-calibration and positioning, please refer to... Figure 3 The imaging acquisition component 8 includes a support frame 81, and an imaging acquisition module 82 is fixedly connected to the bottom wall of the inner cavity of the support frame 81, which can realize the function of acquiring and analyzing the image of the captured product. A photosensitive CCD 83 is fixedly installed on the upper part of the outer surface of the imaging acquisition module 82, which can realize the function of receiving the light irradiated by the photoelectric sensor 9.

[0029] To achieve the purpose of supporting the product, please refer to... Figure 4 The supporting mechanism 3 includes a fixed frame 31. Several clamping plates 32 are slidably connected in an annular array on the upper side of the fixed frame 31. The upper ends of the outer surfaces of the clamping plates 32 are fixedly connected to a limiting plate 33. The lower end of the outer surface of the fixed frame 31 is fixedly connected to the middle of the upper end of the outer surface of the carrying plate 24.

[0030] After placing the product that needs to be calibrated and positioned in the middle of the inner cavity of the fixed frame 31, the clamping plates 32 are slowly inserted into the slots at the four corners of the upper end of the fixed frame 31 by holding the limiting plate 33, so that the product and the photoelectric sensor 9 are located at the same position.

[0032] The working principle of this utility model is as follows: When a specified product needs to be calibrated and positioned, the product is first placed stably in the middle of the inner cavity of the fixed frame 31, and then inserted into the corresponding slots through the limiting plate 33. At this time, the power of the motor 4 is turned on, which drives the fixed support plate 51 to start rotating. At this time, the annular guide frame 52 will support and guide the connecting frame 61. At the same time, the two transmission gears 72 will mesh with the inner surface of the inner gear ring 62 and the outer surface of the outer gear ring 63, and will move along the sliding groove between the outer annular plate 22 and the inner annular plate 23 and the sliding groove between the inner annular plate 23 and the carrying plate 24, respectively. When one of the two photosensitive CCDs 83 rotates to be completely aligned with the front of the product placed in the inner cavity of the fixed frame 31, the light emitted by the photoelectric sensor 9 will be sensed by the photosensitive CCD 83 in time, and the image will be captured and analyzed by the corresponding imaging acquisition module 82. At this time, the motor 4 receives the signal and stops rotating, thus completing a self-calibration positioning.
