The technical solution of the utility model is:
A kind of online aluminium film measuring thickness device comprises detecting sensor module, computer data processing module, data disaply moudle;
The output terminal of this detecting sensor module exports electric signal the input end of this computer data processing module to, and the output terminal of described computer data processing module exports thickness data to the input end of described data disaply moudle;
Described detecting sensor module comprises that infrared light emitting head and infrared light that many groups are corresponding in twos receive head.
Described computer data processing module links to each other by the RS232 serial port with described data disaply moudle.
Described every group of infrared light emitting head is relative with infrared light reception two, apart from 10mm.
Described infrared light receives a use frequency-selecting amplifier and the logical filter of band, converts light signal to electric signal output.
The CPU of described computer data processing module is AM89S52, also comprises A/D converter, ROM and RAM.
Described data disaply moudle is a HITECH PWS6600C-P LCD.
The histogrammic mode of described data disaply moudle is presented at the thickness data of a breadth on the screen.
Compared with prior art, the beneficial effects of the utility model are:

For making this novel online aluminium film measuring thickness device have antijamming capability, not influenced by other light, so use infrared pulse light modulated emission principle, receiving end uses frequency-selecting amplifier and the logical filter of band, to reduce interference of stray light, obtains thickness signal.
Description of drawings
Fig. 1 is the structural representation of this novel online aluminium film measuring thickness device.
Embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is further described in detail, but should limit protection domain of the present utility model with this.
See also the structural representation of this novel online aluminium film measuring thickness device of Fig. 1.This novel online aluminium film measuring thickness device is made up of three parts:
(1) detecting sensor module: this part is installed in the vacuum chamber, and the output terminal of this detecting sensor module exports electric signal the input end of this computer data processing module to, thereby after converting light signal to the thickness electric signal, is sent to outside the vacuum chamber.
This detecting sensor module comprises that infrared light emitting head and infrared light that many groups are corresponding in twos receive head.Every group of infrared light emitting head is relative with infrared light reception two, the about 10mm of distance.
(2) computer data processing module: the thickness electrical signal conversion that spreads out of in the vacuum chamber is become digital quantity, with mathematical model in the computing machine degree data are handled then, obtain thickness data.
The output terminal of this computer data processing module exports thickness data to the input end of described data disaply moudle; Described computer data processing module links to each other by the RS232 serial port with described data disaply moudle.
The CPU of described computer data processing module is AM89S52, also comprises A/D converter, ROM, RAM and I/O mouth.
(3) data disaply moudle:
Obtain thickness data, change LCDs over to, use histogrammic mode, the thickness data of a breadth is presented on the screen through serial RS232 mouth.
Described data disaply moudle can adopt HITECH PWS6600C-P LCD.
The concrete method of work of this novel online aluminium film measuring thickness device is:
Online aluminium film measuring thickness device has an infrared light emitting head and an infrared light to receive head, and two is relative, the about 10mm of distance.Film passes through from the centre, and the infrared light of infrared light emitting head emission passes film, is received head by infrared light and receives.The variation in thickness of coating can cause the variation of light penetration, and infrared light receives the also variation thereupon of infrared light that head is received, receives head at last and converts light signal to electric signal output.
A pair of measuring head can only be measured a point, for whole breadth is measured,, can measure whole breadth so form delegation with many group emitting and receiving heads, and corresponding with delegation a plurality of evaporation sources.
For making online aluminium film measuring thickness device have antijamming capability, not influenced by other light, so use infrared pulse light modulated emission principle, receiving end uses frequency-selecting amplifier and the logical filter of band, to reduce interference of stray light, obtains thickness signal.
