Description
Technical field
The present invention relates to a kind of substandard products pick-up unit and method of multi-joint plate, particularly a kind of multi-joint plate that is applied to surface mounting technique (SMT), and whether the daughter board that must detect on the multi-joint plate is pick-up unit and the method that substandard products are beneficial to put part.
Background technology
Circuit board about the manufacturing of SMT (surface mounting technique) industry, all stride forward towards compact target, circuit board as mobile phone, its area is more and more little, if each technology is all only made the little circuit board of monolithic, and obviously too waste, and having no the output value can say, therefore the also situation of plate is arranged, a plurality of little circuit boards are merged into a slice large circuit board, this large circuit board is called multi-joint plate 1 (as shown in Figure 1) again.
When multi-joint plate 1 was made with the SMT technology, because the speed of equipment is more and more fast now, and part was more and more little, and under compact requirement, the number of plies of circuit board is also more and more many, causes product percent of pass relatively more and more low.
In addition, because the price of some part is not low, therefore higher-priced part must not be plugged on the problematic little circuit board (calling daughter board 11 in the following text), based on this reason, circuit board factory is when producing multi-joint plate 1, must detect, and problematic, underproof daughter board 11 stamped defective mark (badmark) 12, for the identification of SMT factory, in other words, meet the daughter board 11 of defective mark 12, SMT factory just skips and will not put part.
After the detection of aforementioned substandard products, circuit board factory promptly stamps defective mark 12 to underproof daughter board 11, this defective mark 12 is the agreement between circuit board factory and the SMT factory, for example with the fixed position blacking on the daughter board 11, promptly form defective mark 12, and the daughter board 11 with defective mark 12 is substandard products; Otherwise this fixed position is if on behalf of this daughter board 11, not blacking promptly be certified products.
Part is put by known SMT factory, is to arrive when putting the part location at arbitrary multi-joint plate, absorbs one by one on each daughter board of this multi-joint plate with portable video camera whether defective mark is arranged earlier, then just begins to put part.In other words, it is put the part operation and can't continue to carry out, because must wait for the detection action of the multi-joint plate of each sheet, has formed idle time (free time).
Multi-joint plate 1 with eight-in-one is example (or merging two the four multi-joint plates of unifying), if defective mark of video camera picked-up needs 0.5 second, then eight daughter boards need 4 seconds idle time (free time) altogether, so its production capacity=8/[26+4+ (0.5*8)]=23%; But if can save this and be used for absorbing the time that defective mark slatterns the time, its production capacity=4/[26+4+ (0)]=13.2%, therefore, 23%-13.2%=9.8% has increased by about 10% production capacity approximately.
Therefore, how to design a kind of can going one by one and on each sheet daughter board 11 of interpretation whether defective mark 12 is arranged, and can avoid again the high price part is mispluged on the daughter board 11 of existing defective mark,, be the problem of desire solution of the present invention so as to promoting production capacity.
