Problems solved by technology
[0005] First of all, from the perspective of control principle, the current PCB CNC drilling system composed of PC + motion control card is difficult to meet the technical requirements of multi-station, high speed, and high precision; It takes the longest time. The conventional control method only compresses the Z-axis stroke to achieve the purpose of fast drilling. This conventional method cannot shorten the drilling time very well.
[0006] Based on the above description, no matter the control system or control method used for PCB drilling in the existing market, there are great technical defects in the real-time control ability.

The invention discloses a control system and method for PCB numerical control hole drilling. The control system comprises a controller, an industrial control computer, a servo driver, an XYZ axis motor and a position detector, the input end, the first output end and the communication end are arranged on the controller, and the communication end of the controller is in interactive communication with the industrial control computer through the Ethernet; the controller transmits downloaded hole drilling data through the first output end of the controller to the servo driver, the servo driver drives the X axis and the Y axis on the XYZ axis motor to transversely move and the Z axis on the XYZ axis motor to vertically move, and the position detector detects transversely-moving location of the X axis and the Y axis and transmits location signals to the controller through the input end of the controller. The efficient and reliable control system and method are developed for PCB numerical control hole drilling according to the technical shortcomings in real-time control capacity of an existing system, the requirement of a PCB for efficient numerical control hole drilling is met, the PCB numerical control hole drilling efficiency is improved, and the PCB manufacturing cost is further reduced.
Description
[0001] Technical field [0002] The invention involves the field of CNC, especially a control system and method for PCB CNC drilling. [0003] Background technique [0004] With the development of PCB towards high density and multi -layered development, the PCB pore diameter is getting smaller and smaller, and the hole positions are becoming more dense, and higher requirements are placed on CNC drilling efficiency.CNC drilling processing costs account for more than 30%of the cost of PCB board.Increased CNC drilling efficiency is of great significance to reduce the cost of PCB production and improve the competitiveness of electronic products.The PCB drilling control system hardware structure and multi -axis collaborative drilling control method are the two important factors affecting the efficiency of PCB drilling. [0005] First of all, from the principle of control, the PCB CNC drilling system composed of the current PC+motion control card is difficult to meet multi -station, hi...
