Specific embodiment
As shown in Figure 1, the industrial frequency AC mash welder intelligent controller includes: main control chip module, for handling input letter
Number, and control instruction is exported to trigger welding circuit and control the cylinder movement of welding equipment；Synchronous signal acquisition circuit is used
Come according to AC power waveform to main control chip module output sync pulse signal；Thyristor gating circuit can receive master control
The control instruction of chip module, and trigger welding circuit；Cylinder control circuit, the control that can receive main control chip module refer to
It enables, and the welding executing agency of welding machine is driven to act；Enabling signal input circuit is used to refer to main control chip module input starting
It enables；Human-computer interaction circuit is used to main control chip module input control parameter；Power supply processing circuit, for connecting external electrical
Source simultaneously provides independence to main control chip module, synchronous signal acquisition circuit, thyristor gating circuit and cylinder control circuit respectively
Power supply.
It is illustrated in figure 2 the power supply processing circuit of the utility model embodiment, 24V and 5V is separately supplied in circuit
Electricity is inputted from different power transformer taps, thus is avoided that control machines high-current consumption impacts chip power supply；
Chip 5V power supply is powered using DC-DC switching power source chip LM2575, not by grid fluctuations affect.
Due to it is silicon-controlled be a kind of half control device, it can control open, without can control shutdown, be merely able to exchange
Electric zero-crossing switching, control welding current are the silicon-controlled turn-on time of control in fact, that is, according to the zero crossing of alternating current come
Time-delayed trigger is silicon-controlled.Therefore the order of accuarcy of alternating current synchronous signal is extremely important for welding current control.Existing control
Device is all the pulse signal that ac signal is processed into synchronizing cycle.Generally there are two types of abnormal for common synchronization signal: 1, believing
Number deformation, China Power Grids frequency is 50hz, then the positive and negative half-wave of a cycle all should be 10ms, many controller synchronization signals
The case where output is that the longer negative hemiwave time of positive half wave times is shorter, when controlling electric current in this way, just will appear one
Directional current is bigger than normal always, influences service life of a machine；2, interference signal, it is mainly on same power grid that multiple pulses, which occurs, in half of cycle
Other high-power switching circuits generate, if system controls silicon-controlled according to interference signal, it is unstable just to will appear electric current, substandard products
Rate is high.Fig. 3 show the synchronous signal acquisition circuit of the utility model embodiment, and circuit is powered to amplifier using positive and negative 15V, protected
It is synchronous with alternating current sine wave to demonstrate,prove pulse signal low and high level；For interference signal, in control method, carry out at software filtering
Reason, i.e., after main control chip module receives first pulse synchronous signal, controlled by timer, in next 9ms
Not return pulse signals.
Human-computer interaction circuit is made of charactron key indicator lamp, realizes parameter setting, reading and display, controller work
The display of state.
In the work of enabling signal input circuit, closure switch, controller works according to the parameter of setting, and control is electrical
Cylinder and silicon-controlled work.
The circuit diagram of the cylinder control circuit of the utility model embodiment is as shown in Figure 4.Circuit is controlled by control instruction
The air inlet outlet of cylinder realizes the pressurization and release of welding electrode.
The circuit diagram of the thyristor gating circuit of the utility model embodiment is as shown in figure 5, using the isolated arteries and veins of KMB518
It rushes transformer and controls silicon-controlled triggering, circuit is simple, reliable trigger, high-low pressure security isolation.
