Abstract
A high-temperature tunnel kiln for production of tuning fork crystal comprises a kiln body; the wall of the kiln body is provided with a plurality of grooves; heating tubes are mounted in the groove. The high-temperature tunnel kiln is characterized in that thermocouples are mounted in the grooves, the kiln body is provided with a temperature control system, the temperature control system comprises the thermocouples, relays and a PLC (programmable logic controller) control system, the thermocouples are arranged in the grooves, and two ends of each relay are connected with each heating tube and the PLC control system. The high-temperature tunnel kiln has the advantages that the sensors are used for acquiring temperature, the relays are controlled via the PLC control system to discover high-speed on and off of the heating tubes, multi-circuit control is achieved, the whole system has a short reaction time, and temperature precision is up to +/-1 DEG C.
Description
Technical field
The invention belongs to tuning fork crystal production field, be specifically related to a kind of production tuning fork crystal high temperature tunnel furnace.
Background technology
High temperature tunnel furnace is for the oven dry of the reflow welding of SMT element, printed circuit and electronic product and powder body material, solidify, binder removal etc.This stove adopts independent warm area isolation structure, the black brilliant pipe heating of far-infrared ceramic heating plate or pottery, and infrared radiation face width is wide and without dead angle.Control and adopt single loop intelligence regulative mode, there is stable, the easy to adjust feature of temperature control.Be applicable to very much the batch production of factory and enterprise.
For make high temperature resistant crystal in high temperature tunnel furnace wafer and pedestal welding quality high, must strictly control welding temperature.Traditional approach adopts single temp controlled meter to control separately single heat-generating pipe, complex circuit, if heating simultaneously when multichannel is controlled, can be because of the excessive impact system of electric current.
Summary of the invention
The object of the invention is to overcome problems of the prior art, a kind of simple in structure, high temperature tunnel furnace that temperature control is effective is provided.
For realizing above object, technical solution of the present invention is: a kind of production tuning fork crystal high temperature tunnel furnace, comprise body of heater, on the furnace wall of described body of heater, be provided with some grooves, described groove is provided with heat-generating pipe, it is characterized in that: in described groove, thermocouple is installed, on described body of heater, is provided with temperature control system, described temperature control system comprises relay and PLC control system, and the two ends of described relay are connected with heat-generating pipe, PLC control system respectively.
Described PLC control system comprises PLC controller, A/D converter and touch-screen, and described thermocouple is electrically connected to A/D converter, and described relay is electrically connected to PLC controller.
In described groove, heat sink is installed, described heat sink is electrically connected to PLC controller.
The present invention compared with prior art, has the following advantages:
1, the present invention's sensor collecting temperature, realizes the high speed break-make of heat-generating pipe with PLC control relay, realized multichannel control, and the whole system reaction time is short, and accuracy of temperature control can reach ± and 1 ℃.
2, the present invention is arranged on heat-generating pipe, thermocouple and cooling system in groove, so not only can be so that the heating efficiency of heat-generating pipe reaches maximum and the control of temperature control system to temperature of being more convenient for.
3, the present invention arranges heat sink in groove, when furnace body temperature is too high, can realize the fast cooling of body of heater, and temperature control effect is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is temperature control block diagram of the present invention.
In figure: body of heater 1, furnace wall 2, groove 3, heat-generating pipe 4, thermocouple 5, temperature control system 6, relay 7, PLC control system 8, PLC controller 9, A/D converter 10, touch-screen 11, heat sink 12.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the present invention is further detailed explanation:
Referring to Fig. 1-Fig. 2, a kind of production tuning fork crystal high temperature tunnel furnace, comprise body of heater 1, on the furnace wall 2 of described body of heater 1, be provided with some grooves 3, described groove 3 is provided with heat-generating pipe 4, thermocouple 5 and heat sink 12, on described body of heater 1, be provided with temperature control system 6, described temperature control system 6 comprises relay 7 and PLC control system 8, described PLC control system 8 comprises PLC controller 9, A/D converter 10 and touch-screen 11, described thermocouple 5 is electrically connected to A/D converter 10, described relay 7 is electrically connected to PLC controller 9, the two ends of described relay 7 are connected with PLC controller 9 with heat-generating pipe 4 respectively, described heat sink 12 is electrically connected to PLC controller 9
The course of work of the present invention is: the target temperature that each road heat-generating pipe 4 place groove 3 is first set on touch-screen 11, and it is write in PLC controller 9, when heat-generating pipe 4 is started working, the thermocouple 5 that is positioned at groove 3 starts to gather the temperature of groove 3, and signal is sent to A/D converter 10, the signal of changing by A/D converter 10 imports PLC controller 9 into, after relatively, PLC controller 9 is exported pwm pulse by program, control the break-make of multicircuit relay 7, make heating tube 4 heating or turn-off, and the real time temperature data of collection are shown to touch-screen 11 in order to monitoring.When body of heater 1 excess Temperature need to be lowered the temperature, also can control the fast cooling that the heat sink 12 that is positioned at groove 3 is realized body of heater 1 by PLC controller 9.
