Problems solved by technology

However, in the actual application of the PCB CNC drilling machine drilling process, the inventor found that when the PCB CNC drilling machine is drilling, the drill bit rotates at a high speed, causing high-speed friction between the drill bit and the PCB board, causing the drill bit and the PCB board to heat up instantaneously, exceeding the temperature of some PCBs. The temperature that the board can withstand makes the PCB board stick
Especially for PCB boards that require a processing temperature below 25°C, it is difficult for existing CNC drilling machines to achieve
In addition, in the process of drilling the PCB board, a large amount of fine dust will be generated, which is difficult to be cleaned by vacuum equipment, polluting the environment
In addition, the high temperature generated by the drill bit during drilling also affects the service life of the drill bit and other components of the drilling machine

Embodiment 1

[0024] This embodiment provides a kind of numerical control drilling machine, comprises drilling machine 101 and is used to place the drilling workbench 102 of panel 104, is provided with cooling groove 103 below described drilling machine 101, is provided with in the described cooling groove 103 and is used for cooling. liquid, the drilling table 102 is placed in the liquid in the cooling tank 103 .

[0025] In this embodiment, the board 104 may be a PCB, or other boards 104 that need to be drilled, and there is no special limitation here. When using the numerical control drilling machine for drilling, the plate 104 is fixed on the drilling table 102, and the drilling table 102 is placed in the liquid in the cooling tank 103, and then the drilling machine The drill bit 105 of 101 extends under the liquid surface to drill holes on the plate 104 placed in the liquid. The heat generated by the drilling will be absorbed by the liquid in the cooling tank 103 , thereby reducing th...

Embodiment 2

[0033] Such as figure 2 As shown, the present invention also provides a kind of numerical control drilling method, comprising:

[0034] 201. Fix the plate on the drilling table;

[0035] 202. After the plate is fixed on the drilling table, the drilling table is placed in the cooling tank under the drilling machine, and the plate is immersed in the cooling liquid in the cooling tank;

[0036] 203. Extend the drill bit of the drilling machine under the liquid to drill holes in the plate.

[0037] In this embodiment, the liquid may be cooling water or frozen water. After the plate is immersed in the liquid, and then the plate is drilled, the liquid can take away a large amount of heat generated by drilling, thereby reducing the temperature of the drill bit and the plate. In addition, the dust generated by drilling will stay in the liquid to avoid polluting the space environment.

[0038] In order to better solve the technical problems of the present invention, on the basis o...

Abstract

The invention discloses a numerical control drilling machine and a numerical control drilling method. The numerical control drilling machine comprises a drilling machine body and a drilling workbench for holding a plate, a cooling tank is mounted under the drilling machine body and is filled with cooling liquid, and the drilling workbench is mounted in the liquid in the cooling tank. According to the numerical control drilling machine, the plate is drilled in the cooling liquid, a drill bit and the plate are cooled by the liquid so that the plate adhesion caused by overhigh temperature is avoided. Because the plate is drilled in the cooling liquid, the dust generated by drilling is held in the liquid, and the environment pollution problem caused by the dust is solved. The drill bit and other components of the drilling machine are in contact with the cooling liquid, so that the temperature is lowered in working, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of plate drilling, in particular to a numerical control drilling machine and a numerical control drilling method. Background technique [0002] Printed circuit board PCB drilling is a key process in the production process of printed circuit boards. The level of its processing technology and manufacturing equipment will directly affect the quality, performance and cost of PCB. PCB drilling methods mainly include mechanical drilling and laser drilling. At present, more than 90% of PCB drilling processes in the world use CNC mechanical drilling, and laser drilling only accounts for about 10%. Therefore, CNC machine tool drilling is the mainstream of PCB precision drilling. [0003] PCB CNC drilling machine is based on CNC technology, through the coordinated movement of X, Y, and Z coordinates, it controls the X, Y axes to move quickly and accurately to the drilling position on the PCB board on the drilling table, and is...
