PCB three-dimensional drilling equipment and control method thereof

Abstract

The invention provides PCB three-dimensional drilling equipment. The PCB three-dimensional drilling equipment comprises an operation supporting frame, a supporting plate, a drilling machine and a pushing plate, wherein the supporting plate is supported on the operation supporting frame; the drilling machine is supported on the supporting plate, the distance between the drilling machine and the supporting plate can be adjusted, and drilling operation is achieved; and the pushing frame is arranged on one side of the supporting plate in a sliding mode and can push and fix a PCB. According to thePCB three-dimensional drilling equipment, the distance between the supporting plate and the drilling machine is adjustable, the pushing frame can push and fix the PCB, the drilling angle of the drilling machine can be adjusted, and therefore, three-dimensional adjustment of the drilling angle of the PCB is achieved. The invention further provides a control method of the PCB three-dimensional drilling equipment. The drilling angle of the drilling machine and the distance between the supporting plate and the drilling machine are brought into a fuzzy controller, the drilling speed can be accurately adjusted, the PCB is prevented from being damaged due to too fast drilling, and the material cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical drilling for special equipment, in particular to a three-dimensional drilling equipment for PCB boards and a control method for the three-dimensional drilling equipment for PCB boards. Background technique [0002] In the prior art, PCB, the English full name is Printed Circuit Board, and the Chinese name is printed circuit board, also known as printed circuit board, which is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components . Because it is made by electronic printing, it is called a printed circuit board. Before the appearance of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. Now, although PCB manufacturing technology has been developed for nearly 100 years, the quality and efficiency of PCB manufacturing still ...

AI Technical Summary

Problems solved by technology

Now, although PCB manufacturing technology has been developed for nearly 100 years, the quality and efficiency of PCB manufacturing still rely heavily on manufacturing equipment and on-site management, especially high-density multi-layer PCB boards, which are difficult to process. In about 60 manufacturing In the process, there may be defective products in each process, so the output rate is generally not high. The production cost of the drilling process accounts for more than 30% of the entire process. If the diameter becomes smaller, it may not be replaced in time, which will cause batches of PCB processing to have a small hole diameter and fail to pass; or the coordinate values ​​​​of the X-axis and Y-axis coordinates of the drill head are abnormal, and the clamp of the main drill on the drill stand If there are abnormal shapes such as tilting and bending, if there is no detection, it will lead to abnormal PCB aperture processing, or even scratch or damage the PCB; in addition, during the PCB drilling process, a large amount of glass fiber materials, copper scraps, etc. are generated. , there are undesirable phenomena such as debris plugged holes, rough hole walls, and partial holes, which even affect the yield of copper plating on the subsequent hole walls of the PCB, reduce the output rate, and waste production costs; in addition, due to the large number of holes in the PCB , the size of the aperture due to the wide variety of design requirements, the drilling tool needs to be replaced frequently during the drilling process, so a tool changing device that suits the PCB drilling equipment is needed. The automatic tool changing machine currently on the market has a rotatable changing The tool arm, the tool changing arm rotates around the center of the tool changing arm between the processing machine and the cutter head, has a large volume, complex structure, expensive price, and is not suitable for PCB drilling equipment and is not easy to maintain
