Description

Automatic unloader that goes up of biax PCB drilling machine

Technical Field

The invention relates to the field of PCB drilling processing, in particular to an automatic loading and unloading device of a double-shaft PCB drilling machine.

Background

The PCB drilling processing is different from other common machine tool processing, when the PCB is processed by a laminating process, the PCB is manually fed, in the drilling processing of the PCB, a backing plate is needed to be arranged below the PCB for preventing a cutter head from damaging a workbench of a machine tool in the drilling processing, the PCB is not processed by a single PCB generally, 1-5 PCBs are stacked together and fixed on the workbench through a pin together with the backing plate below for drilling processing, meanwhile, an aluminum foil paper is needed to be laid on the PCB at the top when the PCB is drilled, the aluminum foil paper mainly takes away heat generated in processing and simultaneously takes away scraps generated in processing, therefore, the aluminum foil paper has huge and indispensable effect in the drilling processing of the PCB, the process is a unique process of the drilling processing of the PCB, when the feeding is manually carried out, the backing plate is required to be firstly mounted, then a plurality of PCBs are mounted, finally the aluminum foil paper is mounted, and finally the PCB is fixed on a workbench of a machine tool through an adhesive tape.

In the production process of the PCB, the PCB needs to be drilled by PCB drilling equipment. In prior art, place the PCB board of treating processing on PCB drilling equipment through artificial mode usually, not only need operating personnel to follow up at the scene always, the human cost is big, and if PCB drilling equipment accomplishes that the operating personnel does not in time trade the material in man-hour, then PCB drilling equipment will be in the shutdown state, thereby lead to the reduction of production efficiency, simultaneously, because the existence of artificial factors such as artifical unloading, lead to the processing technology of PCB board unstable easily, need consider the artificial factor when PCB board processing technology process analysis.

At present, the drilling process of the domestic PCB still adopts the manual feeding and discharging mode to carry out mechanical processing, the mounting mode of the mainstream of the current PCB drilling process is manual mounting and dismounting, the manual feeding and discharging time is very slow, and the processing efficiency is greatly prolonged.
