Harmomegathus data are measured to the circuit board after lamination, for each circuit board, even number harmomegathus data are selected from the harmomegathus data measured, and become a coordinate points according to every two harmomegathus data assemblies, coordinate points is identified in a coordinate system, as shown in Figure 3 C, be scatter diagram that the coordinate points of multiple circuit board is formed in a coordinate system.
When generating coordinate points, for rectangular circuit board, because harmomegathus data can both be measured in every bar limit of rectangular circuit board, namely rectangular circuit board all has two harmomegathus data respectively on long limit and minor face, a harmomegathus data assemblies of the harmomegathus data and minor face that then can get long limit respectively becomes a coordinate points, another harmomegathus data on long limit become another coordinate points with another harmomegathus data assemblies of minor face, make each circuit board coordinate points mark in a coordinate system after, certain regularity can be presented, thus make when being carried out frame point by rectangle frame, minimum rectangle frame can be used all coordinate points to be framed.
When to carry out point heap to circuit board, by carrying out frame point so that point heap is interval in a coordinate system for the rectangle frame of the length of side, if all coordinate points of arbitrary circuit board are all in same rectangle frame, then this circuit board can be divided into the heap representated by this rectangle frame.
When carrying out frame point in a coordinate system by rectangle frame, to ensure that coordinate points all in coordinate system can both be in rectangle frame on the one hand, also will guarantee the minimum number of rectangle frame on the other hand, to avoid point heap too much, cause the inconvenience of subsequent treatment.
Because coordinate points is according to the harmomegathus data genaration of circuit board, in order to accurately judge which circuit board is the coordinate points in coordinate system belong to, can be numbered circuit board when the harmomegathus data of measuring circuit plate, then the number information of circuit board is used to identify the coordinate points generated, to guarantee accurately to judge which circuit board is coordinate points belong to.
As shown in Figure 3 C, coordinate points 306 and coordinate points 308 are the coordinate points of circuit board A, because coordinate points 306 and coordinate points 308 are all in rectangle frame 302, therefore, circuit board A can be divided into the heap representated by rectangle frame 302.
Coordinate points 310 and coordinate points 312 are the coordinate points of circuit board B, and because coordinate points 310 is in rectangle frame 304, and coordinate points 312 is in rectangle frame 302, therefore, can decision circuit plate B be abnormal plate, and all abnormal circuit boards are divided into abnormal heap.After completing and dividing heap to a collection of circuit board, for abnormal heap, a point heap can be re-started, to determine to adopt which kind for the treatment of process to process.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered in the related, there is no the scheme of precise and high efficiency to carry out a point heap to circuit board.Therefore the present invention proposes a kind of new circuit board and divide heap scheme, multiple harmomegathus data of comprehensive same circuit board can carry out a point heap, improve the accuracy that circuit board divides heap, simultaneously, due to for same circuit board, only carry out once dividing heap, therefore improve point heap efficiency of circuit board.
