Description
Technical field
The present invention relates to a kind of printed circuit board (PCB) appearance delection device, also relate to a kind of printed circuit board (PCB) appearance detecting method, belong to electric detective technology field.
Background technology
In the electronic equipment such as household appliances, mobile phone, there are many places all can use and are welded with electronic component and are furnished with wiring " printed circuit board (PCB) ".If the some electronic components forming these circuit do not have firm welding, whole electronic equipment will be caused to run well.Recently, along with the miniaturization of the equipment such as mobile phone, printed circuit board (PCB), also more and more to densification future development, has arrived the stage cannot being carried out accurately, be checked rapidly by naked eyes welding result.
Summary of the invention
The object of the present invention is to provide a kind of printed circuit board (PCB) appearance delection device, solve the technical matters that in prior art, PCB detecting is inconvenient, accuracy in detection is not high.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of printed circuit board (PCB) appearance delection device, comprise host computer, image collecting device, color illumination system and the detection platform for placing printed circuit board (PCB), described color illumination system and image collecting device are arranged at above detection platform respectively, and described host computer is connected by wireless network signal with image collecting device.
Described color illumination system is red, green, blue three look illuminating lamp.
The upper workplace of described detection platform is provided with printed circuit board (PCB) detent, and the lower workplace of detection platform is connected with rotation control mechanism.
Printed circuit board (PCB) liftout attachment is also provided with in described detent.
Described image collector is set to video camera.
Another object of the present invention is to provide a kind of printed circuit board (PCB) appearance detecting method, comprise the following steps:
Step one: open red, green, blue three look illuminating lamp, irradiates face of weld from the top of printed circuit board (PCB);
Step 2: be positioned at the video camera picked-up printed circuit board image directly over printed circuit board (PCB), obtain assorted reflected light, and be uploaded to host computer;
Step 3: rotate detection platform, repeats step one, two, to obtain many groups reflected light picture of same printed circuit board (PCB) different angles;
Step 4: host computer changes according to the look of printed circuit board (PCB) face of weld different angles, i.e. form and aspect shape, judges printed circuit board (PCB) welded condition.
Compared with prior art, the beneficial effect that the present invention reaches: provide a kind of printed circuit board (PCB) appearance detection equipment and its detection method, colored high light mode is adopted to carry out the detection of printed circuit board (PCB) welded condition, even if assemble hundreds of electronic components in the scope less than 1 square millimeter, still just can check its welding result at 25 seconds, accuracy in detection is high, speed is fast, significantly improves the work efficiency that printed circuit board (PCB) outward appearance detects.
