Background technology:
Because the development of microwave vacuum device application, press for high-quality, highly reliable microwave device.The soldered seam of present microwave device is because of the poor quality, and often gas leakage reduces the qualification rate of device and reliability greatly.Correctly brazing temperature and holding time are the key factors that obtains the high-quality soldered fitting.Can it directly has influence on scolder fully fill up the play movement, form firm combining with Base Metal, thereby forms the weld seam that gas seal member is good, intensity is high.At present the temperature-controlled process of the soldering oven that uses is by eye-observation, manual behind indication solder fusing in the soldering oven temp controlled meter is provided with and operates, to reach simultaneously the control to workpiece brazing temperature and holding time.At first this soldering oven needs operating personnel follow the tracks of temperature in the soldering oven at any time, needs in time operate temperature control instrument behind the indication solder fusing, otherwise might cause brazing temperature too high, and workpiece is scrapped.The human factor influence is bigger during secondly this soldering oven operation, in the operating process brazing temperature fluctuation bigger, also difficult precise control of holding time, process consistency is bad, has influenced the quality of workpiece soldering greatly.
The utility model content:
Technical problem to be solved in the utility model is the human factor of getting rid of in brazing process, a kind of automatic brazing control device that is used for soldering oven is provided, by before soldering to some initial setting up of soldering oven, make soldering oven finish soldering automatically, guaranteed the brazing quality of workpiece and the uniformity of technology workpiece.
For solving the problem that prior art exists, the technical scheme of the utility model technical solution problem:
A kind of automatic brazing control device that is used for soldering oven, it is characterized in that: the energized circuit that a band brazing solder is installed on the work supporting block of soldering oven, this energized circuit comprises the ceramic insulation base, the ceramic insulation base is fluted, brazing solder is stamped in ceramic insulation base groove upper end, described brazing solder two ends are pressed with molybdenum electrode, and described molybdenum electrode is wired to the PLC controller, and the PLC controller is connected to temp controlled meter.
Described a kind of automatic brazing control device that is used for soldering oven, it is characterized in that: described brazing solder is placed on the step on ceramic insulation base groove top.
Advantage of the present utility model:
The utility model has compared with prior art increased an energized circuit that has brazing solder on the work supporting block of soldering oven, and is associated with PLC controller, temp controlled meter.When in brazing process, the brazing solder fusing disconnects energized circuit, after this signal is passed to the PLC controller, sends two temp controlled meters of instruction control by the PLC controller again and finishes whole brazing process.After PLC controller and temp controlled meter are carried out some initial setting up, soldering oven has been finished the brazing process of workpiece automatically, reduced operating personnel's workload, got rid of the human factor in the operating process, by accurate control, the uniformity of soldering processes and the brazing quality of workpiece have been improved greatly to brazing temperature and holding time.

The specific embodiment:
Referring to Fig. 1, a kind of automatic brazing control device that is used for soldering oven, the energized circuit of a band brazing solder is installed on the work supporting block of soldering oven, this energized circuit comprises ceramic insulation base 1, ceramic insulation base 1 is fluted, and brazing solder 2 is stamped in ceramic insulation base 1 groove upper end, and described brazing solder 2 two ends are pressed with molybdenum electrode 3, described molybdenum electrode 3 is connected to the PLC controller by lead 4, and the PLC controller is connected to temp controlled meter.
Now utilize Fig. 2, Fig. 3 and Fig. 4 that the utility model course of work is described in detail, the energized circuit that has brazing solder as shown in Figure 1 is housed on the work supporting block of soldering oven of the present utility model, upward configure temperature curve at temp controlled meter 1 (the FP21 temp controlled meter with the SHIMADEN brand is the example explanation), upward configure temperature curve and " PV START " is set at " Y " by Fig. 4 at temp controlled meter 2 (the FP21 temp controlled meter with the SHIMADEN brand is the example explanation) by Fig. 3.Temp controlled meter 1 and temp controlled meter 2 all are set to the external control state, this moment on two temp controlled meters " EXT ' lamp is bright.On PLC, write automatic running program.Operation PLC program, temp controlled meter 1 Fig. 3 temperature curve that brings into operation begins to heat up.Raise with temperature, when the solder fusing in the energized circuit that has brazing solder, energized circuit disconnects, and runs to the D of temperature curve this moment
0Point, this moment, PLC picked up counting, and the time is (t

0).(t
1-t
0) be that temperature that heating rate and soldering work piece by the CD section exceed than solder fusing is calculated and configured on PLC and gets final product.After time is up, promptly arrived the D of temperature curve
1Point, this moment, PLC gave temp controlled meter 1 one " HLD " instructions, and picked up counting simultaneously, and the time is D
1E
1The section time also is holding time of brazing, needs to configure on PLC before the program operation.Carrying out the soldering insulation this moment.After time is up, PLC gave temp controlled meter 1 one " HLD " instructions again, is equivalent to the E of temperature curve this moment
1The point.Delay time and give temp controlled meter 1 one " RST " instructions after one second, stopped the temperature control effect of temp controlled meter 1 this moment.PLC gives 2 one operating instructions of temp controlled meter in time-delay after one second, because of " the PV START " of temp controlled meter 2 is set at " Y ", temperature curve directly jumps to E from the E point
1Point, the temperature lowering curve that brings into operation finishes until moving to temperature curve.
The explanation of above example only needs to place brazing solder 2 on the energized circuit of brazing solder having, and on temp controlled meter 1 and temp controlled meter 2 corresponding temperature curve is set, and sets D on PLC
