Multi-connecting board bad-product detecting device and method

Abstract

Then invention provides multi-plate faulty detection devices and method used in place pieces of equipment, including the purchase of equipment for the transmission of the plate and has a more prepared, home of the district and the completion of at least one conveyor components and pieces at home district. The detection devices including scanners and processing devices, scanners used to scan the failure of the more board and mark on the area in preparation, processing device from electrical connections in the home between the machine and scanner to pieces in home before the operation, had already pre-scan the data which will be imported from the home machine. The machine from home not only for qualified home-plate pieces, but also save the public know uptake failed to mark squandered by the idle time to buy pieces of ongoing operations, production can elevate.

Description

technical field [0001] The present invention relates to a defective detection device and method for multi-connected boards, in particular to a multi-connected board applied to surface mount technology (SMT), and it is necessary to detect whether a sub-board on a multi-connected board is a defective product to facilitate Device and method for detecting components. Background technique [0002] The circuit boards manufactured by the SMT (Surface Mount Technology) industry have all moved towards the goal of thinness and shortness. For example, the circuit boards of mobile phones have become smaller and smaller. If only a single small circuit is manufactured in each process Boards are obviously too wasteful and have no output value at all. Therefore, there are situations where multiple small circuit boards are combined into one large circuit board. This large circuit board is also called multi-connection board 1 (as shown in Figure 1 ). [0003] When the multi-board 1 is manuf...

In other words, the placement operation cannot continue, because it has to wait for the detection action of each multi-connection board, forming idle time (idle time)

[0007] Take the 8-in-1 multi-board 1 as an example (or combine two 4-in-1 multi-boards), if it takes 0.5 seconds for the camera to pick up an unqualified mark, then the eight sub-boards need a total of 4 seconds of idle time (idle time ), so its production capacity=8 / [26+4+(0.5*8)]=23%; but if the time wasted for ingesting unqualified marks can be saved, its production capacity=4 / [26+ 4+(0)]=13.2%, therefore, 23%-13.2%=9.8%, about 10% more capacity
