Detailed description of the invention

In conjunction with the drawings and specific embodiments, the present invention is illustrated:

As it is shown in figure 1, a kind of thin glass cutting on line device, described cutting on line device includes cylinder 4, directive wheel 5 and Cutting knife 6；The cylinder axis 11 of described cylinder 4 outfan is fixedly connected with knife rest 12, and is fixed with directive wheel in the lower section of described knife rest 12 5；Described cutting knife 6 is fixed on the side of directive wheel 5, lifts with described knife rest 12 together with described directive wheel 5；Described Cutting on line device also includes for controlling the proportional solenoid I 3 of described cutting knife action, proportional solenoid II 2；Described Proportional solenoid I 3 is connected with described proportional solenoid II 2, and electrically connects with control system 10 respectively；Described ratio electromagnetism Valve I 3 correspondence is positioned at the heavy sheet glass 1 on thin glass both sides and arranges；During described proportional solenoid II 2 correspondence is positioned in the middle part of thin glass Between thin glass 7 arrange；In this embodiment, the thickness of heavy sheet glass is 3mm, and the thickness of thin glass is 0.7mm；Proportional solenoid I 3, Proportional solenoid II 2 regulates applicable cutting pressure respectively, a proportional solenoid I 3 for edge's 3mm glass 1, another Proportional solenoid II 2 press pin is to middle 0.7mm(or following) glass 7,

Utilizing the technique that thin glass is cut by a kind of thin glass cutting on line device, it specifically comprises the following steps that

1) first speed V of cutting knife 6 it is set in control system 10, measures and draw intermediate thin glass 7 in the thin glass of required cutting Width L1, the width of intermediate thin glass two ends heavy sheet glass 1 is respectively L2 and L3, and calculates what cutting knife 6 ran in L1 section Time T1, the time T2 that cutting knife runs in L2 section, the time T3 that cutting knife runs in L3 section；

2) cylinder 4 action, makes knife rest 12 drive described directive wheel 5, cutting knife 6 to decline, and make described directive wheel 5, cutting knife 6 with The end thereof contacts of described thin glass；If described directive wheel 5, cutting knife 6 first with heavy sheet glass 1 end thereof contacts that width is L2；
