Abstract

The invention relates to the field of circuit board detection, particularly a circuit board detection device with roller compaction module with self-compaction function. The circuit board detection device comprises a machine frame, camera modules, light source modules, a roller compaction module and a fixing bracket, the camera modules and light source modules are respectively arranged on the upper part and lower part of the roller compaction module; the roller compaction module comprises an upper roller assembly and a lower roller assembly; the fixing bracket comprises a sliding seat and a vertical rod; both ends of the vertical rod are fixedly provided with the sliding seat; the sliding seat is arranged on columns on both sides of the machine frame in a sliding mode; the sliding seat is provided with an upper roller seat; the upper roller assembly is provided with at least two upper rollers in parallel; the upper rollers are installed on the upper roller seat; and a fixed seat is clamped by the two sides of the machine frame and provided with a lower roller seat. The roller compaction module is provided with the upper roller assembly and lower roller assembly, thereby avoiding warping and other uneven phenomena when the circuit board passes through the compaction module.

Description

technical field [0001] The invention relates to the field of circuit board detection, in particular to a circuit board detection device with a roller pressing module having a self-pressing function. Background technique [0002] The circuit board inspection device is an advanced online 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, so as 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 o...

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] According to the conclusions obtained from theory and experiments, a bidirectional camera can obtain better results when taking pictures of PCB boards with the same thickness, but there must be a pressing device with an adaptive function and can press the circuit board during the shooting and testing process. , otherwise there will still be shadows or unclear situations during shooting
