To achieve these goals, the technical solution of the utility model is as follows:
A kind of pick-up unit of the liquid crystal panel for touch-screen production technology, it is characterized in that, described pick-up unit comprises the light emission system be made up of several generating lasers and laser controller, the light receiver system formed with the laser sensor of generating laser quantity Matching, light processing equipment, described generating laser and laser sensor lay respectively at above and below liquid crystal board, and described light processing equipment is connected by correspondence with light receiver system.
Further, described generating laser all keeps vertical with liquid crystal panel, laser thickness sensor.
Further, described generating laser and laser sensor are all equally spaced is arranged on above and below liquid crystal panel.
In order to process abnormal liquid crystal panel in time, described pick-up unit also comprises the warning device be connected with light processing equipment.
A method for the thickness of on-line checkingi liquid crystal panel, above-mentioned detection device is arranged on liquid crystal panel and transmits exit, described transmission exit is also provided with glass sensor, and its step detecting liquid crystal panel thickness is as follows:
(1) after the glass sensor transmitting exit has sensed liquid crystal panel, generating laser launches first group of laser beam to liquid crystal panel;
(2) light of laser beam after the refraction of liquid crystal panel bilayer of laser transmitter projects is accepted by laser sensor;
(3) signal that laser sensor accepts is transferred into light processing equipment, is converted into corresponding thickness data by light processing equipment;
(4) laser controller can control the transmission frequency of generating laser, after first group of radiating laser beams completes, repeats step one to step 3;
(5) after the glass sensor transmitting exit senses do not have liquid crystal panel, generating laser quits work;
(6) also simultaneously comprehensive collection carried out to the thickness of liquid crystal panel at liquid crystal panel by the process that transmits to step (5) by step (1);
(7) data that light processing equipment is responsible for gathering are compared process, if exceed allowed band, then the warning device be attached thereto gives the alarm.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model structure is simple, and utilize laser sensor to measure liquid crystal panel thickness, its precision can reach 0.5um.
(2) process that the utility model utilizes liquid crystal panel to transmit gathers the thickness data of each position of liquid crystal panel simultaneously, can not affect productive temp.
(3) generating laser of the present utility model and laser sensor can adjust flexibly according to the size of liquid crystal panel.
(4) the utility model can adjust laser emission frequency by laser controller, to reach the object of image data flexibly according to demand.
(5) the utility model can be arranged on each equipment outlet in OnCell technique on demand, realizes on-line checkingi.
(6) the utility model can be processed the thick abnormal liquid crystal panel of box in time by warning device.
