Description
Technical field
The utility model relates to the temperature control equipment in a kind of cast welding machine lead melting furnace and casting pond.
Background technology
Accumulator pole group is critical process together with the production of busbar cast welding battery, directly affects the quality and performance of battery.Utmost point group cast welding technological parameter comprises bus-bar alloy, cast temperature, mold temperature, casting time, delay, insertion depth, cool time etc.The wherein only temperature of guaranteed rational lead melting furnace, cast temperature, the cast welding moulding of guarantee utmost point group and bus-bar.Therefore to the control of the temperature of cast welding machine lead melting furnace, cast temperature etc., be the key that guarantees cast welding processing quality.Traditional temperature is controlled the definite value switch method of temperature-control by that adopt more, by hardware circuit or software, calculates the relation between current temperature value and goal-setting value, and then the heater of system is carried out to break-make control.This temperature control method principle is fairly simple, cost is low, but cannot overcome the hysteresis quality of variations in temperature, and control accuracy is low, cannot realize high-precision temperature and control.
Utility model content
The utility model will solve the problem that in prior art, temperature control method lags behind, control accuracy is low, thereby the temperature control equipment in a kind of cast welding machine lead melting furnace and casting pond is provided.
The technical scheme that the utility model addresses the above problem is as follows:
The temperature control equipment in cast welding machine lead melting furnace and casting pond, it by a PLC, two with the intelligent temperature controller of solid-state relay output, be arranged on two K type thermocouples in lead melting furnace and casting pond, two groups of solid-state relays and heater respectively and form; Wherein, the input of intelligent temperature controller is connected with thermocouple, gathers respectively the plumbous liquid temp in lead melting furnace and casting pond; The signal output part of intelligent temperature controller is connected with the input of solid-state relay, and the output of solid-state relay is connected with heater, for the control to heater, and the power output of control heater; The lowest temperature warning output of intelligent temperature controller is connected with PLC, the prompting of reporting to the police for temperature anomaly.
In the utility model technique scheme, two K type thermocouples detect respectively the plumbous liquid temp in lead melting furnace and casting pond, and the temperature signal detecting is inputed to respectively to two intelligent temperature controllers.Intelligent temperature controller compares tested temperature value and setting value, when dut temperature departs from setting value, intelligent temperature controller carries out PID computing according to the deviation of measuring-signal and setting value, output control signal is to solid-state relay, drive IGCT zero cross fired on-off circuit, change the output duty cycle in fixing phase, thus the power output of control heater.The lowest temperature warning output of intelligent temperature controller is connected with PLC, when dut temperature lower than set lowest temperature time, by PLC output control signal to warning device.The pid control parameter of intelligent temperature controller is set by the method for certainly adjusting.
The utlity model has following beneficial effect:
1. the utility model utilizes two K type thermocouples to detect the plumbous liquid temp in lead melting furnace and casting pond, and carry out PID computing by intelligent temperature controller, by intelligent temperature controller, export control signal to solid-state relay, thereby the heating by solid-state relay control heater to plumbous liquid, controls the plumbous liquid temp in lead melting furnace and casting pond to realize;
2. the utlity model has the feature that temperature control precision is high, this is because temperature in its running can show in real time, and reliable, easy to maintenance, and temperature control precision remains on positive and negative 1 degree Celsius, can effectively guarantee the quality of utmost point group cast welding.
