Technical field
This utility model relates to furnace temperature tester technical field, in particular, particularly to a kind of intelligence furnace temperature tester.
Background technology
Along with processing technique improves constantly, surface mount process is constantly strict, and the temperature curve of welding plays in whole flow process
Crucial effect.For continuous electronic device and applicable scope, there is different oven temperature profile.But display in furnace temperature
Temperature is not accurately and is continuous print curve, it is impossible to the process of the whole welding of exact knowledge.And for different brands
Tin cream material, oven temperature profile is also different.
Thus, being badly in need of such a equipment in production technology measures the curve of furnace temperature, analyzes regulation setting value.The most a lot
Foundries or processes factory all do not have the large-scale joint factory of such test equipment, only minority just to use.And use
Or external import, expensive (RMB is about 20,000 yuan).For this reason, it is necessary to a kind of intelligent furnace of design
Temperature tester solves the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, intelligent furnace temperature tester easy to use.
In order to solve posed problems above, the technical solution adopted in the utility model is:
A kind of intelligence furnace temperature tester, including 12 tunnel K-type thermocouples, for detecting the soldering furnace of 12 positions on Board Under Test
Temperature delta data；12 ADC transducers, for carrying out the welding furnace temperature delta data that 12 tunnel K-type thermocouples are detected
AD conversion；Master controller, the data record after being changed by 12 ADC transducers is in a SD card；And PC is eventually
End；Described 12 tunnel K-type thermocouples, 12 ADC transducers, master controller and PC terminal are sequentially connected with.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model uses 12 tunnel K-type thermocouples, i.e. 12 passage multi-point temp curve monitoring records, monitoring range
Extensively；
2, this utility model uses 12 ADC transducers, and precision is high, and speed is fast；
3, this utility model internal data stored number capacity is big；
4, this utility model uses the design of high integration IC, greatly reduces the size of tester；
5, this utility model uses the PC of hommization to operate interface, operates with convenient.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of utility model, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the principle framework figure of intelligence furnace temperature tester of the present utility model.
Fig. 2 is the circuit diagram of K-type thermocouple ADC transducer in intelligence furnace temperature tester of the present utility model.
Fig. 3 is the circuit diagram of master controller in intelligence furnace temperature tester of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and spy
Levy and can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite boundary
Fixed.
Refering to shown in Fig. 1, this utility model provides a kind of intelligence furnace temperature tester, including 12 tunnel K-type thermocouples 1, is used for
The welding furnace temperature delta data of 12 positions on detection Board Under Test；12 ADC transducers 2, for by 12 tunnel K-type thermoelectricity
The even 1 welding furnace temperature delta data detected is AD converted；Master controller 3, for by 12 ADC transducers 2 turns
Data record after changing is in a SD card；And PC terminal 4；Described 1,12 ADC transducers of 12 tunnel K-type thermocouple
2, master controller 3 and PC terminal 4 is sequentially connected with.
Refering to shown in Fig. 2, being the circuit diagram of 12 ADC transducers 2, it uses MAX brand K-type thermocouple mould
Number converter, chip carries the module such as internal temperature compensation and filtering, uses more convenient, reads data by SPI interface.
Precision can reach 0.5 degree Celsius.
Refering to shown in Fig. 3, for the circuit diagram of master controller 3, use ST brand 32 bit processor, gather 12 tunnels
The temperature data of ADC transducer, after the filtering within processing, and the temperature storage in each moment in SD card.
Temperature measuring device of the present utility model uses the K-type thermocouple probe interface of 12 passages, can monitor on Board Under Test 12
The welding furnace temperature change of individual position, uses 12 ADC transducers of outside high accuracy, and conversion accuracy reaches 0.5 DEG C, during conversion
Between bring up to 10mS.Master controller 3 uses 32 bit processors, can record data in SD card, and can record 5G
Data and curves.
Data storing mode of the present utility model, uses off-line to gather data, and tester is followed tested plank and moved together,
The temperature in each moment is recorded.After whole flow process is complete, temperature measuring device connection data wire to computer (PC terminal),
Again the digital independent inside tester out, drawing curve, with the temperature curve arranged compares, that can make adjustment builds
View.
Above-described embodiment is this utility model preferably embodiment, but embodiment of the present utility model is not by above-mentioned enforcement
The restriction of example, other any without departing from the change made under spirit of the present utility model and principle, modify, substitute,
Combination, simplification, all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
