Technical field
The utility model relates to automated optical detection technique field, relates in particular to a kind of automatic optical detecting system.
Background technology
Automated optical detects AOI (Auto-Optical-Inspection) system; It is the image data (generally being converted into digitized view data) that obtains object through optical instrument; Then, compare and analyze with predetermined method, image data is tested and judged with specific template.
When concrete the realization, existing automatic optical detecting system generally uses two kinds of methods:
First kind of camera head is to adopt the linear CCD camera lens, at first, the PCB substrate carried out full plate scanning, then, the image that scans carried out data processing and detection.In the process that the pixel data are obtained, motor promotes single CCD and constantly carries out the horizontal scanning campaign, thereby obtains the image of object.Such detection system and method can be brought several problems: 1. the IMAQ time of linear CCD is longer; 2. because linear CCD obtains is one-dimensional data; In order to obtain 2-D data; Need be equipped with device such as grating and write down the pairing coordinate of each row of linear CCD scanning,, not only increase the complicacy and the cost of system like this owing to the existence of scanning motion and respective feedback position; The precision of images possibly receive the influence of scanning motion precision and reduce simultaneously, finally has influence on accuracy of detection; 3. the use of linear CCD also will certainly increase the complexity of Flame Image Process.
Another kind of camera head is to adopt the area array CCD camera lens, adopts [moving-pause-Cai Tu] pattern, and the PCB substrate is fixed; The camera head scanning of above the PCB substrate, moving; When moving to the predetermined field of view position, picture pick-up device is deadlocked, and carries out IMAQ and target detection.The detecting pattern of this [move-pauses-Cai Tu] not only can have influence on the detection speed of system, and the vibration that brings of moving also can influence the stability of system.
Along with the high speed development of electronic product industry, the status that automated optical detects is also more and more irreplaceable.Simultaneously, stability, false drop rate, loss and the detection speed to system also proposed increasingly high requirement.
The utility model content
Correlation technique problem to above-mentioned proposition; The utility model provides a kind of automatic optical detecting system, adopts the area array CCD camera head, and PCB substrate and camera head are with the route motion of optimum; With minimized number visual field images acquired; And in continuous motion, accomplish IMAQ and substrate measuring ability, improved the detection speed and the stability of system greatly, also reduced the false drop rate of system simultaneously.
To achieve these goals, the utility model provides following technical scheme:
A kind of automatic optical detecting system comprises
The PCB substrate,
The image collecting device that is used for the IMAQ work of responsible PCB substrate is provided with a plurality of CCD camera lenses that the face battle array distributes in the image collecting device,
The mechanical movement means that is used for driven image harvester and PCB substrate motion, mechanical movement means is connected with the PCB substrate,
Image collecting device is connected with computer respectively with mechanical movement means; The software detection platform of the inspection function of the mechanical motion control of being responsible for total system and product is installed in the said computer, and said mechanical movement means is through the motion of software detection platform driven image harvester and PCB substrate.
The technique effect of the utility model is: the system that the utility model provides, be provided with the Array CCD harvester through employing, and avoided the influence that drive unit brings in scanning motion of linear CCD camera head; Simultaneously, reduce the complexity of image processing algorithm, helped reducing the false drop rate of system; Dynamically adopt figure and the instant synchronous realization that detects; Improve detection speed greatly, simultaneously, avoided the influence of mechanical vibration in the image acquisition process again; Strengthened the robustness of system, be specially adapted to repeatedly topography and gather the situation that combinatory analysis detects.
Description of drawings
The front view of the automatic optical detecting system that Fig. 1 provides for the utility model embodiment.
Label declaration among the figure: 11. image collecting devices, 12. computers, 13. mechanical movement means, 14.PCB substrate.
Embodiment
For the technical scheme of the utility model better is described,, introduce the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of automatic optical detecting system.As shown in Figure 1, said system comprises:
The image collecting device 11 that is used for the IMAQ work of responsible PCB substrate 14 is provided with a plurality of CCD camera lenses that the face battle array distributes in the image collecting device 11,
Be used for the mechanical movement means 13 of driven image harvester 11 and 14 motions of PCB substrate, mechanical movement means 13 is connected with PCB substrate 14,
When PCB substrate 14 moved to the position of predetermined field of view, said software detection platform control image collecting device 11 was accomplished IMAQ work.The use of area array CCD has not only reduced the number of times of IMAQ, has saved detection time; And avoided at the linear ccd image gatherer process because the influence that the position feedback error is brought during motor-driven; Simultaneously, the Flame Image Process of area array CCD is fairly simple with respect to linear CCD, helps improving the accuracy of target detection.
Mechanical movement means 13 is drive units of whole checkout equipment, and under the control of said software detection platform, dynamic image acquisition and instant measuring ability are accomplished in the continuous motion that drives said image collecting device 11 and PCB substrate 14.
A kind of automatic optical detecting system that the utility model embodiment provides is specially adapted to repeatedly topography and gathers the situation that combinatory analysis detects.In the continuous motion process of PCB substrate 14 and image collecting device 11, accomplish IMAQ and instant measuring ability.
Be detailed introduction and the explanation that the utility model embodiment is done more than, be merely the preferred embodiment of the utility model, be not used in restriction the utility model.For those skilled in the art, according to the thought of the utility model embodiment, the part that on concrete embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
