In procedures such as numerical control forming milling or drilling, the degree of automation is very low, and feeding and discharging are all needed to be carried out manually. Before manual feeding and discharging, a paperboard is generally placed on a processing table of a PCB forming machine and is adhered with the textured paper around, the paperboard and a table top are fixed, then a spindle clamping knife drills pin avoiding holes in the paperboard, then a small-size knife is replaced, the same positions of the pin avoiding holes are drilled on the table top to form pin holes, then a pin is inserted into the pin holes through a manual or plug-in pin manipulator, the pin holes are in interference fit with the pin, and then a textured paper adhesive tape is torn off. During feeding, firstly, the whole plate material is stacked, then the whole plate material is placed on a paperboard of a table board, and the plate material is fixed and then subjected to milling through the nesting of pins on the table board and through holes of the plate material. After the machine milling plate, the paperboard and the processed PCB plate are jacked up and separated from the pins through the jacking device, the small PCB plates (finished plate) which are processed and formed are manually picked up, stacked and taken away at the moment, then the leftover materials generated in the plate processing process are taken away, finally the jacking device is lowered, and the paperboard falls onto the table top again, so that the blanking process is completed. If a PCB forming machine has a plurality of processing table tops, then need go up the unloading of manual work of mesa one by one, take time by a long time, and in the in-process of unloading is gone up to the manual work, the machine is stop work, has increased the empty probability of machine, has reduced production efficiency, has increased the cost of labor.
