Meet preset value, then shows that thickness meets the requirements, while recording thickness data.
9. the infrared touch-control optical mode adjusting method stated according to claim 7, which is characterized in that the frontier inspection method specifically includes:
In preset region along Y-axis search for white point, when the continuous number of white point be more than preset value, record most on white point coordinates and
White point coordinates under most；
Row search white point where white point in predeterminable area on most will be in X-axis if white point accounting is greater than preset value
Shifting scans for；If white point accounting is less than preset value, X-axis is moved down and is scanned for；When white point accounting reaches preset value,
Current axis as hot spot top along；
Row search white point where white point in predeterminable area under most will be in X-axis if white point accounting is greater than preset value
Shifting scans for；If white point accounting is less than preset value, X-axis is moved down and is scanned for；When white point accounting reaches preset value,
Current axis as hot spot it is following along.
10. the infrared touch-control optical mode adjusting method stated according to claim 7, which is characterized in that calibration tank packet above the scale
Include scale upper left side calibration tank and scale upper right side calibration tank；Below the scale calibration tank include scale lower left calibration tank and
Scale upper right side calibration tank；It is single to adjust the height value of single pixel, right side on the left of correction light emitting devices acquisition plane bottom plate
The height value of pixel, the X-axis position in left side and right side X-axis position；The optical mode transmitter height for adjusting infrared touch-control product obtains
The optical signal of optical mode transmitter transmitting is formed by left spacing and the right side between optical plane and the display plane of infrared touch-control product
Spacing；If the left spacing and right spacing meet preset value, the optical mode transmitter height for completing infrared touch-control product is adjusted.
