Technical Field

[0001] This utility model relates to the field of component testing technology, specifically to an AOI testing device for components. Background Technology

[0002] The application of AOI technology for components has a profound impact on improving production quality and efficiency. Through high-precision cameras and image processing algorithms, it can quickly and accurately detect surface defects, poor welding, missing components, and other problems of components, significantly reducing fatigue errors and subjectivity in manual inspection.

[0003] In the existing technology, traditional optical inspection equipment for electronic components mainly consists of a fixed camera, a light source system, and mechanical transmission components. The fixed camera can achieve image acquisition at a specific angle; the light source system usually uses ordinary LED lights or ring lights to supplement the light source; the mechanical transmission components are used to control the movement of the workpiece or adjust the focal length. All components work together to complete the inspection of the components.

[0004] However, traditional optical inspection equipment for electronic components is difficult to inspect from all angles with a single fixed camera, especially for components with complex three-dimensional structures or multi-layered layouts, which can easily lead to blind spots and further affect the inspection accuracy. To address this problem, this invention proposes an AOI (Automated Optical Inspection) device for electronic components. Utility Model Content

A drive motor is provided at one end of the transmission screw, and the drive motor is fixedly installed in the placement slot. A vent frame is fixedly installed directly behind the placement slot, and a number of linearly equidistant heat dissipation slots are opened on the surface of the vent frame.

[0011] Preferably, the overall cross-section of the positioning plate is in the shape of a "U". The positioning plate is fixedly installed on the upper end of the drive cylinder. A sliding groove is opened on the side wall of the positioning plate. Two sets of fixing members are inserted into the sliding groove. The fixing members can be displaced in the sliding groove. The fixing members include a connecting plate and a positioning screw. Both ends of the connecting plate are inserted into the sliding groove. A threaded hole is opened on the surface of the connecting plate. The positioning screw is screwed into the threaded hole. An anti-slip pad is fixedly installed at the lower end of the positioning screw.

[0024] In use, the components can be secured to the positioning plate 6 by the fixing piece 7, and at the same time, the drive screw 9 is driven to move towards the detection box 3. When it moves to the bottom of the detection box 3, the drive cylinder 8 is used to bring the whole thing close to the main camera 4. With the cooperation of the main camera 4 and the surrounding oblique cameras 5, high-precision image acquisition from all directions and multiple angles can be achieved, so as to accurately detect surface defects and dimensional deviations of components. This avoids the blind spots and misjudgments that may occur in traditional single-view detection.

[0025] Example 2: Based on Example 1, a positioning plate 6 is provided to facilitate the installation of testing components. The overall cross-section of the positioning plate 6 is U-shaped. The positioning plate 6 is fixedly installed on the upper end of the drive cylinder 8. A sliding groove is opened on the side wall of the positioning plate 6. Two sets of fixing parts 7 are inserted into the sliding groove. The fixing parts 7 can be displaced within the sliding groove. The fixing parts 7 include a connecting plate 16 and a positioning screw 17. The two ends of the connecting plate 16 are inserted into the sliding groove. A threaded hole is opened on the surface of the connecting plate 16. The positioning screw 17 is screwed into the threaded hole. An anti-slip pad is fixedly installed at the lower end of the positioning screw 17. Two sets of symmetrical holes are opened on the side walls of the two ends of the movable groove 10. A fixed bearing 12 is fixedly installed on the inner wall of the hole. A transmission screw 9 is fixedly installed on the inner ring surface of the fixed bearing 12.

[0026] During testing, the component can be secured in the positioning plate 6, and the fixing piece 7 can be moved to a suitable position so that the fixing piece 7 is placed above the edges of both ends of the component. At the same time, the positioning screw 17 can be rotated to press the anti-slip pad against the component, thereby completing the installation and fixing of the component.

[0027] Example 3: Based on Example 2, a transmission screw 9 is provided for easy detection. Two sets of transmission screws 9 are provided, and the two sets of transmission screws 9 are symmetrical in structure. A screw nut 13 is fitted on the surface of the transmission screw 9, and a connecting plate 14 is provided between the screw nuts 13. A drive cylinder 8 is provided on the surface of the connecting plate 14. A drive motor 15 is provided at one end of the transmission screw 9.

Several linearly equidistant heat dissipation slots are opened on the surface of the vent frame. The base 1 is generally rectangular in structure. A movable slot 10 is opened on the surface of the base 1. The detection box 3 is located directly above the movable slot 10. The placement slot 11 is opened on the rear side of the base 1.

[0028] To facilitate component inspection, during the inspection process, the positioning plate 6 can be moved to the bottom of the mounting slot 18 by starting the drive motor 15, and the distance between the positioning plate 6 and the mounting slot 18 can be adjusted by the drive cylinder 8.

At the same time, a supplementary light ball 2 is set in the mounting slot 18. Multiple supplementary light balls 2 provide multi-directional supplementary lighting to the surface of the component, avoiding visual blind spots caused by shadows on the component, which would make image acquisition easier.

[0031] Working principle: In actual use, the component can be fixed on the positioning plate 6 by the fixing part 7, and at the same time the transmission screw 9 is driven to move towards the detection box 3. When it moves to the bottom of the detection box 3, the drive cylinder 8 makes the whole thing close to the main camera 4. With the cooperation of the main camera 4 and the surrounding oblique cameras 5, high-precision image acquisition from all directions and multiple angles can be achieved, so as to accurately detect surface defects and dimensional deviations of the component. This avoids the blind spots and misjudgments that may occur in traditional single-view detection.
