Description
Technical field
The present invention relates to a kind of pick-up unit, be specifically related to a kind of wire purity detecting device.
Background technology
The method that detects at present wire purity mainly contains two kinds, one is comparatively accurately chemical composition quantitative analysis method, need to coordinate specialized equipment and personnel to complete in specific laboratory, accuracy of detection be high, sense cycle is long, testing cost is high, is applicable to scientific research institution or wire manufacturer; Another kind is pairing comparision, contrast by the gauge wire of tested wire and same specification, observe the difference of physical parameter, as weight, color, gloss, soft durometer etc., although succinctly convenient, but the experience and the resolution characteristic that need observer, accuracy, consistance are all very poor, and its result can only make reference.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wire purity detecting device, utilizes Seebeck principle, coordinates corresponding Check processing circuit just can demonstrate the purity difference of tested wire and gauge wire.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of wire purity detecting device, comprise power supply, LCD liquid crystal display, single-chip microcomputer, detecting electrode, sample resistance and PTC fire end, described power supply is connected with LCD liquid crystal display, single-chip microcomputer and PTC fire end in turn, described LCD display is connected with single-chip microcomputer, described detecting electrode connects sample resistance, and sample resistance is connected with the A/D end of single-chip microcomputer, is also connected with PTC fire end on described single-chip microcomputer.
Wherein, the method that the present invention detects wire purity is to adopt Seebeck principle, allows tested wire and gauge wire form thermopair, has under the condition of the temperature difference and detects the size of thermoelectrical potential, thereby judge the size of tested wire and gauge wire difference at two end points
The invention has the beneficial effects as follows: detection is quick, result is accurate, data are reliable; Be applicable to different metal materials; Volume is small and exquisite, simple in structure, with low cost, be widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to existing deficiency wire purity detecting device is provided, comprise power supply (1), LCD liquid crystal display 2, single-chip microcomputer 3, detecting electrode 4, sample resistance 5 and PTC fire end 6, described power supply 1 is connected with LCD liquid crystal display 2, single-chip microcomputer 3 and PTC fire end 6 in turn, described LCD display 2 is connected with single-chip microcomputer 3, described detecting electrode 4 connects sample resistance 5, sample resistance 5 is connected with the A/D end of single-chip microcomputer 3, on described single-chip microcomputer 3, is also connected with PTC fire end 6.
Principle of work of the present invention is: material conductor (being called thermocouple wire material or thermode) the composition closed-loop path based on Seebeck effect when two kinds of different components, and the temperature difference at two ends, two abutments, while there is thermograde, in loop, just having electric current passes through, now between sample resistance two ends, just there is electromotive force, the difference existence function relation of this electric potential difference and two kinds of wire compositions.Utilize corresponding Check processing circuit just can demonstrate the purity difference of tested wire and gauge wire, become the best instrument of selecting qualified wire.Check processing circuit is controlled PTC fire end, at 100 degrees Celsius, makes two wire end points formation temperatures poor heating and temperature control, if tested wire meets standard, it is qualified to show, shows that Reinheitszahl, purity are less than 70% demonstration purity too low if variant.70%-100% purity shows continuously
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
