Numerical control machine tool convenient for PCB positioning

Abstract

The invention discloses a numerical control machine tool convenient for PCB positioning. The numerical control machine tool comprises a machine tool platform, a controller and a partition plate, wherein a left side positioning unit is arranged on the inner wall of the machine tool platform, and a right side positioning unit is slidably connected between the front inner wall and the rear inner wall of the machine tool platform; the left side positioning unit comprises a fixing seat, and the fixing seat is fixedly connected to the inner wall of the machine tool platform through a mounting block; and a lead screw is rotationally connected between the inner wall of the machine tool platform and the partition plate, the lead screw is rotationally connected with the outer wall of the fixing seat, the portion, penetrating out of the outer wall of the machine tool platform, of the lead screw is provided with a driving mechanism I used for driving the lead screw to rotate, and the portion, between the fixing seat and the partition plate, of the outer wall of the lead screw is in threaded connection with a fourth hinge seat. According to the numerical control machine tool convenient for PCB positioning, through the cooperation of the structures, the numerical control machine tool can position a rectangular diagonal type PCB positioning hole, and can be suitable for non-standard PCBs with special specifications and can realize the positioning of some PCBs with special shapes.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool for convenient positioning of PCB boards. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board, which is an important electronic component. It is usually placed on an insulating material and made into a conductive pattern of printed circuit, printed component or a combination of the two according to a predetermined design. called a printed circuit. The conductive pattern that provides electrical connection between components on an insulating substrate is called a printed circuit, so that the finished board of a printed circuit or a printed circuit is called a printed circuit board, also known as a printed board or a printed circuit board. CNC machine tools can be used to mill the shape of the PCB board. Since the thickness of the PCB board is relatively thin, t...

Problems solved by technology

[0003] However, the pin shafts of the existing numerically controlled machine tools all fix the pin shaft plate first through the fixing device of the machine tool, and fix it through the coordinate system. After inputting the data of the PCB board, the pin shaft is nailed into the pin shaft by machine tool control or manual calculation. When the pin hole is smaller than the positioning hole of the PCB board, it is very difficult to remove it after processing, which will affect the next milling machine or other processes, which greatly reduces the processing efficiency. The spacing distribution makes it impossible to locate and fix special specifications or non-standard PCB boards
