Preferably, the electrostatic generator can also be substituted by suction vacuum section, and the suction vacuum section is located at described spacing
Light tool bottom.
Preferably, the suction vacuum section is made up of multiple passages and suction vacuum plant, and the passage directly contact is treated
Detect the bottom of product.
A kind of backlight module detection method, it is characterised in that the backlight module detection method is comprised the following steps：
（A）Backlight product to be measured is positioned over spacing lighting among tool；（B）Increase quiet to backlight product by electrostatic generator
Electricity, makes each membrane material of interiors of products adsorb mutually；（C）Recognize backlight product whether there is abnormity point or foreign matter using CCD vision systems, and
Determine whether non-defective unit.
Preferably, the step can also be：（A）Backlight product to be measured is positioned over spacing lighting among tool；(B1) lead to
Cross vacuum suction part and inhale vacuum to backlight product bottom to be detected, each membrane material of interiors of products is adsorbed mutually；(C1) use
CCD vision systems identification backlight product whether there is abnormity point or foreign matter, and determines whether non-defective unit.
Compared with prior art, detection means provided by the present invention, is made by electrostatic generator or suction vacuum section
Obtain backlight product mutually to adsorb or mutually adsorbed because of vacuum because of electrostatic so that foreign matter protrudes, then by CCD vision systems
Identification, increases substantially so that detection efficiency and accuracy in detection.
