The defective item checkout gear of multi-joint plate
Technical field
The utility model relates to a kind of defective item checkout gear of multi-joint plate, particularly a kind of checkout gear, and it is applied to the multi-joint plate of surface mount technology (SMT), and whether the daughter board that detects on the multi-joint plate is that defective item is beneficial to put part.
Background technology
Circuit board about the manufacturing of SMT (surface mount technology) industry, all stride forward to 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 single a slice, and obviously too waste, and having no the output value can say, therefore the also situation of plate occurs, be about to a plurality of little circuit boards and be 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, therefore 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 (hereinafter referred to as daughter board 11), 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, run into the daughter board 11 that defective mark 12 is arranged, SMT factory just skips and will not put part.
After the detection of aforementioned defective item, circuit board factory promptly stamps defective mark 12 to underproof daughter board 11, this defective mark 12 is followed 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 defective item; Otherwise this fixed position is if on behalf of this daughter board 11, not blacking promptly be qualified product.
The part of putting of known SMT factory is to arrive when putting the part location at any 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 begins to put part again.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, thereby forms free time (idle 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 free time altogether, so its production capacity=8/[26+4+ (0.5*8)]=23%; But be used for absorbing the time that defective mark slatterns if can save, then its production capacity=4/[26+4+ (0)]=13.2%, therefore, 23%-13.2%=9.8% has increased by about 10% production capacity.
Therefore, whether how can go one by one has defective mark 12 on each sheet daughter board 11 of interpretation, and can avoid again the high price part is mispluged on the daughter board 11 of existing defective mark, improve production capacity with this, be the big problem that the utility model will overcome and solve.
