Abstract
The invention discloses scanned type automatic optical detection system and method. The system comprises an automatic testing workbench. The automatic testing workbench is provided with a multi-picture display screen and also provided with a plurality of CCD (Charged Coupled Device) cameras in a linear array way. A linear array scanning way is adopted, i.e. a PCB (Printed Circuit Board) substrate is fixed by a clapboard to be detected by the automatic testing workbench, integral scanning for once is carried out above the PCB substrate to be detected through a testing executer, a feedback optical signal is captured by the CCD camera and transmitted to a computer to acquire a complete PCB substrate figure. The scanning way can obviously increase the detection speed, because the image is captured for once by the CCD camera. Due to capturing the integral image for once, the to-be-detected time of the PCB in the automatic testing workbench is greatly shortened and the use ratio is greatly improved, so that the service life of the CCD camera is greatly prolonged, and the frequency and the period for changing the CCD camera are enlarged to the reasonable range to obviously save the maintenance cost of the machine.
Description
Technical field
The present invention relates to SMT (surface mounting technology) technical field, particularly a kind of scan-type automatic optical detecting system and method.
Background technology
SMT (surface mounting technology) be the popular application of present electronics package trade the most widely technology make, can make 40~60% weight reductions 60~80% of electronic product reduced volume with SM T technology.Wherein: the SMT production procedure as shown in Figure 1: by upper trigger, printing machine, chip mounter, reflow machine and lower plate machine the PCB substrate is handled, AOI position 1, AOI position 2 and AOI position 3 correspond respectively to printing machine, chip mounter and reflow machine.AOI (automatic optical detecting system) generally is positioned over above three positions in the SMT production line: AOI position 1, AOI position 2 and AOI position 3.
At present AOI (automatic optical detecting system) on the market is that clamping plate fix PCB to advance the testing platform then to be measured, the CCD camera lens of Electric Machine Control testing platform top, move the image of the PCB in the capture region by the position of CCD camera lens, a width of cloth width of cloth image construction of seizure the image of monoblock PCB substrate.
1. such scan mode is because be that CCD camera lens sectional type is caught image, and catch whole blocks PCB substrate image speed must be very slow.
2. and sweep velocity will cause the seizure image time of CCD camera lens to prolong greatly slowly, access times increase greatly.
3. owing to catch the prolongation of image time and the increase of access times, make that the frequency that the life-span of CCD camera lens significantly reduces, change increases, the cycle shortening, directly cause the maintenance cost of machine to significantly improve.
Summary of the invention
The invention provides a kind of scan-type automatic optical detecting system and method, with serviceable life to the detection speed of PCB substrate, utilization rate, prolongation CCD camera lens.
To achieve these goals, the invention provides following technical scheme:
A kind of scan-type automatic optical detecting system, described system comprises: test table, described automatic test table are provided with many pictures display screen automatically, and the mode of going back linear array on the described automatic testing platform is provided with a plurality of CCD camera lenses.
A kind of scan-type automatic optical detection method comprises that automatic test table, described automatic test table are provided with many pictures display screen, and the mode of going back linear array on the described automatic testing platform is provided with a plurality of CCD camera lenses, and this method comprises:
Described a plurality of CCD camera lens carries out linear array scanning to the PCB substrate.
Technique effect of the present invention is: system and method provided by the invention, what adopt is the linear array scanning formula, be clamping plate fix the PCB substrate enter automatic testing platform to be measured after, by test executing device from PCB substrate to be measured top disposable whole swept-volume, the CCD camera lens captures the light signal of feedback, be transferred in the computing machine, obtain a width of cloth complete PCB substrate figure.Such scan mode is because image is the disposable seizure of CCD camera lens, so detection speed is significantly improved.Because be disposable seizure general image, make the to be measured time of PCB in automatic testing platform shorten greatly, utilization rate improves greatly.Make increase greatly the serviceable life of CCD camera lens, change the frequency and the cycle of CCD camera lens and all expand in the zone of reasonableness, obviously saved the maintenance cost of machine.
