According to the system for controlling the tin melting furnace, the tin melting temperature can be set accurately by inputting numerical values, and tin melting actual temperature numerical values can be displayed in real time, timely set value adjustment by operators is facilitated, the tin melting temperature control accuracy is improved, and the operation is convenient and simple.
Description
Technical field
The utility model relates to a kind of fusing furnace control system, and particularly a kind of tin melting furnace is controlled system.
Background technology
At present, tin melting furnace adopts the mechanical type temperature-adjusting device, carries out temperature through adjusting knob and sets or regulate temperature; Generally inner at tin melting furnace, temperature control circuit board is set, electronic devices and components such as single-chip microcomputer are installed on the circuit board; Form temperature-control circuit, regulate the control potentiometer by the mechanical type adjusting knob, its resistance is as the given contrast signal of temperature; Export temperature-control circuit to; Temperature-control circuit is handled input signal, and the output control signal is controlled the duty of heater, and does not show the actual temperature of molten tin.Owing to adopt the mechanical type potentiometer to set and regulate fusion temperature, usually need adjusting knob repeatedly, to operate not easyly, control accuracy is low; Because can not show the temperature of molten tin in real time; Can not in time regulate the duty of heater, cause molten tin too high or too low for temperature, make welding quality unstable: temperature is too high; Can cause the wiring board foaming or the smell of burning is arranged, and phenomenons such as pad tin amount is few, rosin joint, leakage weldering; Temperature is low excessively, can cause the bump glossiness bright, the more or even weldering of pad tin amount.
Summary of the invention
The utility model can improve molten tin temperature control precision and tin melting furnace control system easy and simple to handle for the technical problem that exists in the solution known technology provides a kind of.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of tin melting furnace is controlled system; Comprise temperature sensor and heater; Also comprise the digital temperature control device, said digital temperature control device comprises temperature indicating device, temperature setting device and heating control apparatus; Said heating control apparatus input is from the signal of said temperature sensor and said temperature setting device; Handle the duty that back output signal is used to control said heater; And outputing signal to said temperature indicating device, said temperature indicating device displays temperature detects numerical value and temperature is set numerical value.
The utility model can also adopt following technical scheme:
Said temperature sensor is an electroheat pair.
Said heater is an electric heating tube.
Said temperature indicating device is a liquid crystal indicator.
Said temperature indicating device is a digital tube display device.
