Description

technical field [0001] The invention relates to the field of circuit board detection, in particular to a circuit board detection device with a light source component having a light-isolation function. Background technique [0002] The on-line optical detector is an advanced on-line inspection technology. It obtains the image information of the surface of the tested part and compares it with the image information of the qualified part to detect whether the tested part is qualified. At present, online optical detectors are used in a wide range of fields, such as to detect PCB boards (printed circuit boards). Due to the complexity of PCB boards, more and more design circuits, and more and more layers, online optical detectors are used The detector to detect the PCB board is far more mature and efficient than the manual detection method, which is more conducive to ensuring the detection accuracy and controlling the product quality. [0003] When the existing online optical dete...

Problems solved by technology

[0003] When the existing online optical detector detects, the PCB board is placed on a flat plate, one surface of the PCB board is detected first, and then the PCB board is turned over to detect the other surface of the PCB board, so that the PCB board cannot be detected at the same time. Two surfaces, resulting in low detection efficiency; in addition, due to slight bending of the tested part, insufficient light intensity of the light source and shadow areas, etc., this will affect the accuracy of the acquired image information, thereby affecting Detection accuracy

[0004] The light source assembly is usually fixed on the rack to illuminate the circuit board, so that the brightness on the surface of the circuit board is sufficient for the camera module to capture a clear image for comparison detection. Often the clearer the captured image, the more accurate the detection result; but due to The surface of the circuit board is uneven, so there will be shadows that affect the detection in the captured image
