Method and device for achieving batched removing of burrs in hole of PCB based on numerical control machine tool

Abstract

The invention discloses a device for achieving batched removing of burrs in a hole of a PCB based on a numerical control machine tool. The device comprises a PCB moving mechanism and a PCB deburring mechanism; the PCB deburring mechanism comprises a machine tool table board, a first push and pull device is arranged at the bottom of the machine tool table board, and is connected with a positioningpin, a first conical part matched with a positioning hole of the PCB is formed on the top of the positioning pin, a deburring drill bit structure is arranged above the machine tool table board, an L-shaped pressing plate is arranged on the side face of the machine tool table board, and is connected with a second push and pull device, a second conical part matched with the PCB is formed on the endface of the L-shaped pressing plate, the PCB moving mechanism comprises a frame for stacking of PCBs and a third push and pull device, and the third push and pull device is connected with a first lifting device. Automatic stacking, grinding and transport of the PCBs can be achieved, the grinding effect is good, and the grinding efficiency is high.

Description

Technical field: [0001] The invention relates to a PCB board processing equipment, in particular to a method and device for removing burrs in PCB board holes in batches based on a numerical control drilling machine. Background technique: [0002] In the PCB manufacturing process, although multiple processes will control the generation of burrs, the problem of burrs in the holes cannot be avoided after the finished board is made. If there are only a small amount of burrs in the holes, it is generally necessary to remove a smaller pin. One poke, the labor intensity is high and the efficiency is particularly low, and it takes a long time. Even the labor cost of processing the burrs in the holes is higher than the price of the PCB board. For large quantities, many holes have burrs, and manual methods are used. cannot be resolved quickly. An existing method is to directly re-drill with a common drill bit based on a CNC machine tool, but the sharp drill bit in this method will da...

Problems solved by technology

[0002] In the PCB manufacturing process, although multiple processes will control the generation of burrs, the problem of burrs in the holes cannot be avoided after the finished board is made. If there are only a small amount of burrs in the holes, it is generally necessary to remove a smaller pin. One poke, the labor intensity is high and the efficiency is particularly low, and it takes a long time. Even the labor cost of processing the burrs in the holes is higher than the price of the PCB board. For large quantities, many holes have burrs, and manual methods are used. there is no quick fix

The existing method is to directly re-drill with an ordinary drill bit based on the CNC machine tool, but the sharp drill bit in this method will damage the hole wall, resulting in a great quality hidden danger, and the efficiency is not high
