Description

Multilayer circuit board multiple piercing machine

The utility model relates to perforating press, particularly relates to a kind of multilayer circuit board multiple piercing machine, belongs to the equipment of making circuit board.

General multilayer circuit board, be with many thin single layer board with glued membrane (PP that contains glass sand) combination, and single layer board or in conjunction with the locating hole system boring out of the ordinary in advance on it of the glued membrane of usefulness, intersection builds up multilayer circuit board more afterwards; And this glued membrane bores the operation of system locating hole, is that many glued membranes are stacked together, and then bores the system locating hole on stacked glued membrane; But,, then make glued membrane produce defectives such as weavy grain appears, white edge, white angle easily if bore the system locating hole with drilling machine because of glued membrane is thin soft material; And because glued membrane is a flexible material, when when boring the system locating hole, drill bit also can't neatly excise glued membrane, produces the glue slag at the locating hole periphery easily, and influences the quality of product.And when boring,,, make between drill bit and the glued membrane because of producing the high heat of caused by relative motion so the velocity of rotation of drill bit is quite high because glued membrane is a flexible material; Because of glued membrane is low melting point material, make glued membrane can produce the phenomenon of thawing in drill hole again, after the system of boring is finished, can be adhered together between glued membrane and the glued membrane, be difficult for its separation.Moreover, with the multilayer circuit board more than six layers is example, because drilling machine once only can bore locating hole of system, and the general circuit plate needs four locating holes at least, if computer motherboard is wanted six or eight locating holes at least, therefore, on glued membrane, bore the mode of system locating hole with drilling machine, it is slow that it makes speed of production, so output is lower, can't effectively reach mass-produced purpose.Use multi spindle drilling machine on glued membrane, to bore the system locating hole if change,, have the shortcoming that the described use bit bore of leading portion is caused, therefore on making, still have and do not attain desirable part though can reach the purpose of quick brill system locating hole.

The purpose of this utility model is to provide a kind of multilayer circuit board multiple piercing machine, overcomes the various disadvantages of existing punching mode, reaches the purpose of improving the punching location condition, improving the punching quality.

The utility model is achieved in that arranges a plurality of drift groups of installing on surrounding below the upper bolster, installing punching die on the position with respect to the drift group above the die shoe, has nib on it with respect to the drift group, be respectively equipped with chute facing each other on the surrounding of die shoe again, can in chute, install the clinching part, by clinching part fixed punch punch die, below punching die, be equiped with a crumb loading funnel by loosening the clinching part in addition with the position of adjusting punching die, can on punching die, place, can on glued membrane, go out locating hole by the drift group of upper bolster below in order to glued membrane in conjunction with multilayer circuit; The surrounding respectively is equiped with the toothrow pedestal below upper bolster, on the toothrow pedestal, offer a plurality of long slot bores, and below the toothrow pedestal, be equiped with a positioning seat, its top is provided with the positioning tooth of corresponding toothrow pedestal, can pass the long slot bore of toothrow pedestal and be arranged in the positioning seat top by set screw, and can be by loosening set screw to adjust the position of positioning seat, below positioning seat, install above-mentioned drift group in addition, and this drift group installs one towards pin in the center of a pedestal, and on pin, be arranged with a spring, on pedestal, be equiped with a plurality of pilot pins of slippage up and down again, and below pilot pin, be equiped with a pressing plate, on the center of this pressing plate, be provided with a perforation that corresponds to towards pin.

Advantage of the present utility model is as follows: 1, glued membrane carries out a punching press and can form a plurality of locating holes simultaneously, so process velocity is fast, improves the speed of producing in enormous quantities, to reduce production costs; 2, can not produce high temperature towards between pin and the glued membrane, behind the formation locating hole, glued membrane itself can not be adhered together, and is convenient to make its separation on the glued membrane; 3, owing to be provided with the crumb loading funnel, consider to be worth doing so be convenient to remove material; But the glued membrane of the various different sizes of 4 punching out.
