The control circuit that the present embodiment provides, by increasing auxiliary reclay, when right on the basis of existing control circuit
During limit switch operation, I/O panel does not directly receive the action of limit switch, but by auxiliary reclay coil electric
Or dead electricity triggers the closed and disconnected of normally opened contact.Owing to auxiliary reclay is less for the impact of small-signal, faint when having
During signal, the coil of auxiliary reclay is unaffected so that I/O panel can reduce the impact of interference signal.Further, since
I/O panel is directly controlled by auxiliary reclay, can the distance between auxiliary reclay and I/O panel can be arranged
More recently, and limit switch is unrestricted with the distance of auxiliary reclay, therefore, it is possible to avoid limit switch to control with I/O
The problem that cable run between making sheet is longer.
On the basis of above-described embodiment, as one preferred embodiment, auxiliary reclay away from I/O panel away from
From for 10mm.It is to be understood that the distance that auxiliary reclay is away from I/O panel 20 is the nearest, then effect is more preferable, but for electricity
Road to arrange difficulty the biggest, in the present embodiment, the distance of the two is a kind of specific embodiment of 10mm, does not represent
Can only be 10mm.In view of cost and the problem cooperated, preferred auxiliary reclay is MY4N-J auxiliary reclay.Permissible
Being appreciated that, which kind of model auxiliary reclay selects can choose according to actual application environment, a kind of concrete answering
Use scene.
Owing under normal circumstances, the voltage of the power supply that I/O panel 20 uses is 12V, in order to reduce hardware device, this reality
Execute and example is chosen the power supply identical with I/O panel 20.It is to be understood that owing to auxiliary reclay model is different, then use
Power specification the most different, the two need with the use of.
The mechanism map of a kind of CNC engraving machine that Fig. 3 provides for this utility model.As it is shown on figure 3, CNC engraving machine includes main
Machine 30, lathe 31, I/O panel 20, also include that the control circuit 21 described in the various embodiments described above, control circuit 21 are controlled with I/O
Making sheet 20 connects, and I/O panel 20 is connected with main frame by control line.
The embodiment of the other parts of the CNC engraving machine in the present embodiment is referred to prior art, and control circuit
The detailed description of the invention of 21 sees above the description of each embodiment, repeats no more here.
The CNC engraving machine that the present embodiment provides, its control circuit is middle by increasing on the basis of existing control circuit
Relay, when operating limit switch, I/O panel does not directly receive the action of limit switch, but by auxiliary reclay
Coil electric or dead electricity triggers the closed and disconnected of normally opened contact.Due to auxiliary reclay for small-signal impact relatively
Little, when there being small-signal, the coil of auxiliary reclay is unaffected so that I/O panel can reduce the shadow of interference signal
Ring.Further, since I/O panel is directly controlled by auxiliary reclay, can be by between auxiliary reclay and I/O panel
Distance can be arranged more recently, and limit switch is unrestricted with the distance of auxiliary reclay, therefore, it is possible to avoid the limit
Switch the problem that the cable run between I/O panel is longer.
Being preferably carried out mode as one, the control line in the present embodiment is 25 pin parallel port control lines.
Above the control circuit of CNC engraving machine provided by the utility model and I/O panel thereof is carried out detailed Jie
Continue.In description, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is and other embodiments
Difference, between each embodiment, identical similar portion sees mutually.For device disclosed in embodiment, by
Corresponding to the method disclosed in Example in it, so describe is fairly simple, relevant part sees method part and illustrates.
It should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle, also may be used
So that this utility model is carried out some improvement and modification, these improve and modify the protection also falling into this utility model claim
In the range of.
