The specific operation is that firstly, a standard board is taken, an operator weighs the weight of each layer of core boards and PP specification models of the material number according to the correct combination sequence in a programmable electronic balance 16 according to a PCB stacking drawing, the accumulated weight of each layer of core boards and PP specification models is arranged in a control computer 23, in the high multilayer PCB combination process, the programmable electronic balance 16 feeds back the weight information to the control computer 23, if the weight change is within the arrangement range, a PASS is displayed on a display 27, if the core boards with the same layer serial numbers of different material numbers are placed or the semi-solidified PP specification is misplaced for the second time, the weight information is inconsistent with the set value, at the moment, the display 27 displays NG, flashes in the field of the actual weight, and simultaneously gives out an alarm sound.
The operator judges whether the combination sequence and specification of the material numbers are correct according to the information prompted by the display 27, and immediately carries out error correction, so that the situation that the high multilayer board is found to be wrong after combination or lamination is completed, and irreversible loss is caused is avoided.
In conclusion, through four steps of collection, feedback, processing and output of visual signals and weight signals, whether the combination sequence and the model specification of the combination are abnormal or not is automatically identified through equipment, and the combination sequence and the model specification of the combination are intuitively displayed to an operator through a human-computer interface, so that the work load of the operator is greatly reduced, and the occurrence of combination errors is avoided. At the same time, the CCD camera 22, the programmable electronic balance 16, the control computer 23, the display 27 and the workbench 3 are integrated together, so that the space is saved and the operation is convenient.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
