Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a multi-angle imaging device for testing circuit devices. Background Technology

[0002] Circuit boards contain a large number of electronic components. After these circuit devices are manufactured, they need to be inspected to ensure that they can be used normally. During inspection, images of these circuit devices need to be taken and then sent to a computer for comparison to check for defects in their appearance. Existing imaging devices generally use multiple industrial inspection cameras set up from multiple directions to take images of the circuit devices. Although they can observe the general appearance information of the circuit devices, the shooting angle of each industrial inspection camera is limited, which has certain drawbacks. At the same time, the use of multiple industrial inspection cameras also increases costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-angle imaging device for testing circuit devices, which solves the technical problems of limited imaging angle and high cost of existing imaging devices.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-angle imaging device for detecting circuit devices, comprising a hollow base, a central shaft fixed inside the hollow base, the top of the central shaft extending to the outside of the hollow base and fixed with a detection platform, a rotary drive mechanism disposed inside the hollow base, a second motor mounted on one end of the rotary drive mechanism outside the hollow base, an "L"-shaped rotating arm fixed on the output shaft of the second motor, a translation drive mechanism disposed at the end of the rotating arm away from the rotary drive mechanism, and an industrial inspection camera mounted on the translation drive mechanism;

[0005] The rotary drive mechanism includes a motor 1 installed inside the hollow base. A gear 1 is fixed on the output shaft of the motor 1. A rotating arm is provided on one side of the gear 1 and meshes with the teeth on the outer wall of the rotating arm. The rotating arm is "L" shaped and rotatably connected to the central shaft. The end of the rotating arm away from the central shaft extends to the outside of the hollow base and is movably connected to an adjusting arm. A motor 2 is installed on the adjusting arm, and an adjusting bolt is threaded onto the outer wall of one end of the rotating arm.

[0006] Preferably, the translation drive mechanism includes a motor three mounted on a rotating arm, a gear two fixed on the output shaft of the motor three, a translation rod on one side of the gear two and meshing with the tooth groove on the outer wall of the translation rod, the translation rod being slidably disposed at one end of the rotating arm away from the rotation drive mechanism, and an industrial inspection camera being mounted at one end of the translation rod.

[0007] Preferably, the outer wall of the translation rod is provided with a limiting groove that slides in contact with one end of the rotating arm.

[0008] Preferably, a ring-shaped supplementary light is fixed on the outer wall of the industrial inspection camera by a fixing bracket, and the illumination surface of the supplementary light is parallel to the industrial inspection camera.

[0009] Preferably, the center point of the industrial inspection camera and the inspection platform are on the same vertical plane.

[0010] Preferably, a ring-shaped supplementary light is fixed at the edge of the surface of the detection table, and the illumination surface of the supplementary light is an inwardly inclined structure.

[0011] By employing the above technical solution, this utility model provides a multi-angle imaging device for detecting circuit devices, which has at least the following beneficial effects:

[0012] This multi-angle imaging device for circuit components uses a rotary drive mechanism, a second motor, and a rotating arm. The rotary drive mechanism drives the industrial inspection camera to rotate horizontally, while the second motor and the rotating arm drive the industrial inspection camera to rotate vertically. When these two mechanisms work together, a single industrial inspection camera can be used to capture images of circuit components from multiple angles, achieving 360° imaging without blind spots. This increases the imaging range and reduces inspection costs.

[0013] This multi-angle imaging device for circuit components uses a translation drive mechanism. When a defect is detected at a certain location on the circuit component, the industrial inspection camera can be moved closer to that location using the translation mechanism, thereby achieving more detailed imaging. This helps staff accurately determine whether the defect at that location affects the use of the circuit component. Attached Figure Description

[0020] 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.

[0021] Circuit devices are components in electronic circuits used to perform specific functions. These devices can be passive or active, and testing circuit devices is an important step in ensuring the reliability and performance of electronic equipment.

[0022] Example 1:

[0023] Due to the limitations of existing technologies, such as limited shooting angles and high costs, please refer to... Figures 1-3 This utility model provides a multi-angle imaging device for testing circuit devices, which can achieve 360° shooting without blind spots, thus improving the shooting range and reducing the testing cost. The device includes a hollow base 1, a central shaft 2 fixed inside the hollow base 1, the top of the central shaft 2 extending to the outside of the hollow base 1 and fixed to a testing platform 3, a rotary drive mechanism 4 inside the hollow base 1, a motor 5 mounted on one end of the rotary drive mechanism 4 outside the hollow base 1, an "L"-shaped rotating arm 6 fixed on the output shaft of the motor 5, a translation drive mechanism 7 at the end of the rotating arm 6 away from the rotary drive mechanism 4, and an industrial inspection camera 8 mounted on the translation drive mechanism 7. In use, the circuit device is placed at the center of the testing platform 3, and then, under the action of the rotary drive mechanism 4, the motor 5, and the rotating arm 6, the rotary drive mechanism can drive the industrial inspection camera 8 to rotate horizontally, while the motor 5 and the rotating arm 6 can drive the industrial inspection camera 8 to rotate vertically. After the two movements are combined, a single industrial inspection camera 8 can be used to achieve multi-angle shooting of the circuit device.

[0024] Existing imaging devices typically use multiple industrial inspection cameras 8 positioned in multiple directions to capture images of circuit components. While this allows observation of the general appearance of the circuit components, the angle captured by each industrial inspection camera 8 is limited. Therefore, please refer to... Figure 2 The rotary drive mechanism 4 includes a motor 401 installed inside the hollow base 1. A gear 402 is fixed on the output shaft of the motor 401. A rotating arm 403 is provided on one side of the gear 402 and meshes with the teeth on the outer wall of the rotating arm 403. The rotating arm 403 is L-shaped and rotatably connected to the central shaft 2. The end of the rotating arm 403 away from the central shaft 2 extends to the outside of the hollow base 1 and is movably connected to an adjusting arm 404. A motor 5 is installed on the adjusting arm 404, and an adjusting bolt 405 is threadedly connected to the outer wall of one end of the rotating arm 403. By utilizing the operation of the motor 401 and the meshing action of the gear 402 with the rotating arm 403, the motor 5 and the rotating arm 6 on the adjusting arm 404 are driven to rotate horizontally, so that the circuit device can be photographed from any horizontal direction. Under the action of the adjusting bolt 405, the operating height of the industrial inspection camera 8 can be adjusted according to the actual use requirements.

[0025] During shooting, the image clarity is largely related to the light. However, the amount of light at the shooting location is limited. Therefore, a ring-shaped supplementary light 10 is fixed on the outer wall of the industrial inspection camera 8 by a mounting bracket 9, and the illumination surface of the supplementary light 10 is parallel to the industrial inspection camera 8. When the industrial inspection camera 8 is shooting, the supplementary light 10 illuminates the side of the circuit device in the shooting direction, thereby improving the image clarity.

[0026] Furthermore, to ensure that the industrial inspection camera 8 can capture images of the circuit components from all angles, the center point of the industrial inspection camera 8 and the inspection platform 3 are on the same vertical plane.

[0027] Because some circuit components are irregular, using a single supplementary light 10 to provide supplementary lighting may result in dark areas. Therefore, a ring-shaped supplementary light 21 is fixed at the edge of the surface of the detection stage 3, and the illumination surface of the supplementary light 211 has an inwardly inclined structure. The light emitted by the supplementary light 211 is tilted upward, thereby avoiding the problem of unclear images caused by dark areas formed by irregular circuit components.

[0028] Example 2:

[0029] The existing industrial inspection camera 8, after photographing circuit components, suffers from difficulty in further improving image clarity due to the distance between the camera and the components. Therefore, please refer to... Figure 3The translation drive mechanism 7 includes a motor 701 mounted on the rotating arm 6. A gear 702 is fixed on the output shaft of the motor 701. A translation rod 703 is provided on one side of the gear 702 and meshes with the tooth groove on the outer wall of the translation rod 703. The translation rod 703 is slidably disposed at the end of the rotating arm 6 away from the rotation drive mechanism 4. An industrial inspection camera 8 is mounted at one end of the translation rod 703. When a defect is detected at a certain location on a circuit device, the translation mechanism can be used to move the industrial inspection camera 8 closer to that location, thereby achieving more detailed imaging and helping the staff to accurately determine whether the defect at that location affects the use of the circuit device.

[0030] Furthermore, since the translation rod 703 is cylindrical, in order to avoid the translation rod 703 from rotating on the rotating arm 6, a limiting groove 704 is provided on the outer wall of the translation rod 703 to slide in contact with one end of the rotating arm 6; through the limiting effect of the limiting groove 704 and one end of the rotating arm 6, the translation rod 703 will not rotate.
