Problems solved by technology

[0007] The keyboard input of the computer only requires the input port matrix to reduce the number of input points. However, there are a large number of input and output commands in the operation of the machine tool, and it is necessary to provide a CNC machine tool operation panel with fewer input / output ports and low cost. circuit board

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0026] attached figure 2 It is a circuit board for a numerical control machine tool operation panel according to the present invention, and the circuit board is provided with 4 common ports 1, 16 input ports 2 and 12 output ports 3, wherein any one of the common ports 1 and The 16 input ports 2 are respectively connected on and off to form 4*16 input points, that is, the circuit board has 4*16 input lines, such as image 3 shown.

[0027] Any one of the common ports 1 and 12 of the output ports are respectively on-off connected to form 4*12 output points, that is, the circuit board has 4*12 output lines, such as image 3 shown.

[0028] In this embodiment, a diode and a single-pole single-throw switch are connected in series between the input port 2 and the common port 1 on any one of the input lines, such as image 3 shown.

Abstract

The invention discloses a circuit board for an operation panel of a numerically-controlled machine tool, wherein the circuit board is provided with n1 public ports, n2 input ports and n3 output ports; each of n1, n2 and n3 is a natural number which is not smaller than 2; any one of the public ports is respectively connected with the n2 input ports in an on-off manner, so that n1*n2 input lines are formed; any one of the public ports is respectively connected with the n3 output ports in the on-off manner, so that n1*n3 input lines are formed. According to the circuit board for the operation panel of the numerically-controlled machine tool, only (n1+n2+n3) ports are arranged, but n1*n2 input points are formed, and n1*n3 output points are formed, so that the input or output of n1*n2*n3 operating commands can be realized, the number of the input / output ports is few, and the cost of the machine tool is low.

Description

[0001] technical field [0002] The invention relates to a circuit board, in particular to a circuit board for an operation panel of a numerical control machine tool. [0003] Background technique [0004] With the continuous development and progress of industrial automation, the functions of CNC machine tools are becoming more and more powerful. The diversification of machine tool functions leads to the continuous increase of the operation commands that need to be defined by the machine tool. If the previous point-to-point input / output method is still used, and each operation command corresponds to an input or output port, the multiplied input or output ports will make the operation panel of the CNC machine tool very large, and the cost of the machine tool will continue to increase. [0005] At present, there are many ways to reduce the number of input / output points. Among them, the methods to reduce input points are: ①Input point merging; ②Single-button start-stop contro...
