AOI detection device used for PCB welding spot detection

Abstract

The invention belongs to the technical field of detection devices, and discloses an AOI detection device for PCB welding spot detection, and the AOI detection device comprises a case, the top of the case is fixedly provided with an operation table, the rear end of the top of the operation table is fixedly provided with a supporting frame, the top of the supporting frame is movably provided with a sliding frame, the top of the sliding frame is fixedly provided with a mounting frame, and the mounting frame is fixedly provided with a clamping groove. And a detector and a light sensor are movably mounted on the front surface of the mounting frame. Through the sliding frame, the mounting frame, the limiting groove and the positioning groove, the positions of the sliding frame, the mounting frame, the detector and the threaded sleeve can be adjusted through the limiting groove and the positioning groove, and meanwhile the effect of adjusting the position of the optical sensor can be achieved; and under the cooperation of a locking rod and a locking sleeve as well as a connecting shaft and a fixing plate, the positions of the sliding frame, the detector and the threaded sleeve can be respectively fixed, so that the effect of detecting and positioning workpieces with different sizes is achieved.

Description

technical field [0001] The invention belongs to the technical field of detection devices, in particular to an AOI detection device used for detection of PCB solder joints. Background technique [0002] AOI inspection equipment, also known as AOI optical automatic inspection equipment, has become an important inspection tool and process quality control tool for electronic manufacturing to ensure product quality; therefore, how to choose and use AOI optical automatic inspection that suits your own requirements from many AOI brands Equipment has become a matter of great concern to the majority of electronics manufacturing workers. [0003] At present, the use of AOI automatic detection devices is becoming more and more widespread. Although the existing AOI detection devices can also achieve the function of daily detection, because they are installed and fixed by bolts, although the installation is very stable, it also limits the detection.

[0003] At present, the use of AOI automatic detection devices is becoming more and more widespread. Although the existing AOI detection devices can also achieve the function of daily detection, because they are installed and fixed by bolts, although the installation is very stable, it also limits the detection. The scope of use of the equipment makes it difficult to adjust the equipment according to the actual size and shape of the detected workpiece, so that it is suitable for continuous detection of workpieces of different sizes, thereby reducing the practicability of the equipment and bringing inconvenience to the detection

[0004] Moreover, since most of the AOI detection devices in the laboratory need to detect batches of product workpieces, it is necessary to load and accurately position each workpiece to be detected, so that the detection device can measure accurate detection results. Some detection equipment is difficult to automatically and accurately position according to the distance between different workpieces, which also brings inconvenience to the detection and reduces the detection efficiency.

[0005] At the same time, since the inspection equipment needs to inspect batches of workpieces, the purpose of efficient processing has been achieved, and the purpose of inspection is often not only to detect unqualified products, but more importantly, to eliminate unqualified products. However, the existing inspection equipment is in the At the same time of detection, it does not have the function of automatically rejecting unqualified products according to the detection structure, so it needs to be improved
