Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically an integrated PCB board wiring visual inspection device. Background Technology

[0002] PCB, or Printed Circuit Board, is the support structure for electronic components and the carrier for electrical connections, widely used in the electronics field. Its quality directly affects the performance, reliability, and stability of electronic products. With the development of electronic technology, electronic products are becoming smaller, more multifunctional, and higher-performance, continuously increasing the requirements for PCB integration and precision. This makes the quality inspection of PCB wiring lines a crucial link in ensuring the quality of electronic products.

[0003] Traditional visual inspection devices often use fixed-angle light sources, which makes it difficult to ensure uniform illumination on the PCB board surface. Due to the complex wiring on PCB boards, different areas have different light reflection and absorption characteristics. Under a fixed light source, some areas are prone to glare and shadows, interfering with image quality and affecting the accuracy of defect identification. For example, when inspecting fine lines, reflections can obscure the details of the lines, making it difficult to detect defects such as short circuits and open circuits.

[0004] With the miniaturization and multi-functionality of electronic products, the integration of PCB boards has increased, and their structures have become increasingly complex, containing a large number of micro-components, blind and buried vias, and multi-layer wiring. Fixed light sources cannot meet the lighting needs of different structural features simultaneously. For locations such as deep holes and the bottom of components, light cannot reach effectively, creating blind spots in detection.

[0005] When inspecting fine features such as line width deviations and minor solder joint defects, existing light sources struggle to provide suitable illumination to highlight subtle differences. Inappropriate lighting angles can also lead to insufficient contrast between defect features and normal areas, reducing inspection accuracy and failing to meet high-precision inspection requirements.

[0042] In this embodiment, the rodless cylinder 38 is mounted on the movable block 34 via the connector 37. The movable block 34 is threadedly connected to the screw 33 and slidably connected to the guide rod 35. The two ends of the screw 33 are respectively connected to the adjusting handwheel 36 and the rotary motor 31, and the two ends of the guide rod 35 are respectively fixedly connected to the inner sides of the two ends of the bearing mounting seat 32.

[0052] When the telescopic cylinder 22 extends or retracts, it drives the connecting seat 23 and the PCB board inspection table 26 to slide on the guide rail 24 via the slider 25, thereby realizing the horizontal movement of the PCB board.

[0053] The structure of telescopic cylinder 22, guide rail 24, and slider 25 enables horizontal movement of the PCB board, facilitating inspection of different positions on the PCB board and improving the comprehensiveness of the inspection.

[0054] The rotary motor 31 rotates, driving the screw 33 to rotate, causing the moving block 34 to slide on the guide rod 35, thereby driving the lighting device 4 to move horizontally; at the same time, the adjusting handwheel 36 can also manually rotate the screw 33 to move the moving block 34.

[0055] An adjustment handwheel is provided on the outer side of one end of the bearing mounting base 32, which makes it more convenient to adjust manually when needed; the PCB board moving device 2, lifting and traversing device 3, lighting device 4, camera 17, etc. are integrated in the visual inspection box 1, which has a compact structure, occupies little space, and the components work together to improve inspection efficiency.

The camera 17 is mounted on the camera mount 16 to take pictures of the PCB board wiring. The central control device 13 processes and analyzes the captured images to determine whether there are any problems with the PCB board wiring.

[0057] The central control device 13 facilitates the control and data processing of the entire inspection process, reduces the difficulty of operation, and improves the degree of automation of inspection.
