Embodiment

Step (1): integrity detection, mainly carry out the integrity detection of flexible CuCNT composite Nano transparent conductive film, the luminotron that gathers by a row sends light beam, on the opposite of luminotron receiving tube in a row is installed, by being carried out whether foraminate detection of film having or not of light;

Step (2): planarization detects, and the method that mainly adopts the CCD shooting and carry out graphical analysis detects the planarization of flexible CuCNT composite Nano transparent conductive film.The CCD camera lens that places the both sides, top of motion film to be furnished with respectively the laser knife of scanning and to be arranged symmetrically with, laser knife scans by certain sequential, CCD receives the image on the film, if the image that CCD receives is the straight line of a rule, shows that film has good planarization;

Step (3): light transmission detects, the main simulation sensitizing tube that is arranged in the high power fluorescent tube above the motion film and is arranged in below the motion film that adopts forms, small gap is installed above the sensitizing tube, the light light transmission film of the fluorescent tube above the film and slit are received by nethermost simulation sensitizing tube, if the light intensity that receives is consistent, and in certain scope, show that film has qualified light transmission, otherwise then the light transmission of film is defective;

Step (4): reflective detects, and the method that mainly adopts the CCD shooting and carry out graphical analysis is to the reflective detection of flexible CuCNT composite Nano transparent conductive film.Place the both sides, top of motion film to be furnished with respectively the light modulated projection of black and white piece and the CCD camera lens that is arranged symmetrically with, CCD receives the black and white calcspar picture that is incident upon on the film, if the black and white piece of the image that CCD receives has uniform gray scale, show that film has qualified reflective;

Step (5): wearing quality detects, and adopts the roller that is tied with soft cloth that is installed in above the motion film to detect.In the motion of film, roller can contact by the film of certain setting below it, then uses the reflected image that CCD receives this place, and image is analyzed, to check by the surface state of friction place;

Step (6): anti-ly knock detection, adopt the smooth derby of high-frequency little quality that the film in the motion is carried out knocking of stipulated number, then use CCD and carry out image recognition, knocked the surface state at place with check;

Step (7): conductivity detection, adopt a plurality of in twos in groups electrodes, the film of frequent contact movement, and respectively organize the power on/off situation of electrode by certain sequence equipment, then carry out the A/D conversion by the voltage to receiving electrode, analyze its data, to judge the electric conductivity between different distance on the film;

Step (8): process by above-mentioned detection and computer data, image, defective position and defect type are indicated, process in order to carry out manual intervention.

The present invention has following beneficial effect:

1. detect under normal temperature, normal pressure, normal humidity and carry out, lower to the environmental requirement that detects;

2. the method for operation break-down computation machine data and graphical analysis is carried out the detection of specified content with flexible CuCNT composite Nano transparent conductive film, and defective locations and the defect type of testing result is indicated, is conducive to the manual process intervention; This detection has promoted the automated production of flexible CuCNT composite Nano transparent conductive film

Claims (1)

1. the detection method of a flexible CuCNT composite Nano transparent conductive film comprises that step in the following order carries out:

Step (1): integrity detection;

Step (2): planarization detects;

Step (3): light transmission detects;

Step (4): reflective detects;

Step (5): wearing quality detects;

Step (6): anti-ly knock detection;

Step (7): conductivity detection;

Step (8): defective locations and type code;

It is characterized in that: detection is to carry out synchronously in the production of flexible CuCNT composite Nano transparent conductive film, carries out in normal air pressure, room temperature and humidity, and all testing results can be identified and Automatic Logos defect type and position by computing machine.
