Principle of work of the present invention is as follows:
Liquid crystal panel to be measured is placed on bearing tray, and under the control of PLC, bearing tray moves, and through First Line array camera, by First Line array camera, scanning shoot is carried out in the front of liquid crystal panel; Now, vacuum adsorption plate is waited at the first connection (being that bearing tray is with respect to the output of First Line array camera).
After bearing tray is in place, vacuum adsorption plate moves down, and arrives the position approach liquid crystal panel, then air-breathing by outside air-breathing cylinder, by liquid crystal panel vacuum suction to the plate body bottom surface of vacuum adsorption plate.The vacuum adsorption plate lifting that makes progress is subsequently moved, and vacuum adsorption plate turn 90 degrees by rotary cylinder dextrorotation, and moves along the lateral frame of carrier unit; In moving process, through the position of the second line-scan digital camera, by the second line-scan digital camera, the reverse side of liquid crystal panel is scanned.
After the reverse side of liquid crystal panel being scanned by the second line-scan digital camera, vacuum adsorption plate moves the conveying device top for liquid crystal panel to be measured is sent, vacuum adsorption plate moves down, and arrive the position that approaches conveying device (being travelling belt), and carry out vacuum release, lose after suction, liquid crystal panel is due to the effect of self gravitation, gently drop on conveying device (being travelling belt) upper, conveying device starts subsequently, and liquid crystal panel is sent fast; When liquid crystal panel is sent arrival assigned address, by laser sensor, detected, travelling belt stops motion.
In aforesaid operations process, bearing tray is being delivered to liquid crystal panel the first connection (being that bearing tray is with respect to the output of First Line array camera) and after liquid crystal panel is picked up by vacuum adsorption plate, bearing tray is return initial position fast; Vacuum adsorption plate is putting down liquid crystal panel to conveying device (being travelling belt) afterwards, also return fast the first connection, and drive in the other direction (counterclockwise) 90-degree rotation to get back to original state by rotary cylinder, for detecting next liquid crystal panel, prepare.
Because liquid crystal panel detect to need faster speed and compared with the scheme of robotization, the front that the defect of liquid crystal panel both may appear at liquid crystal panel also may appear at the reverse side of liquid crystal panel, this just requires, in a censorship process, to complete the detection of positive inverse plate surface simultaneously.Positive detection is relatively easy for mechanism design, the detection relative complex of reverse side some, design proposal provided by the present invention can address the above problem.And because liquid crystal panel is a kind of weak parts that are highly brittle, easily in testing process, there is inspection and damage, thus mechanical arm de-clamping turn-over should not be used, and for the more artificial turn-over of the demand of robotization; Therefore, detect the reverse side of liquid crystal panel, just need in the situation that not carrying out mechanical turn-over, carry out; Loading Move tool in the present invention adopts vacuum adsorption plate, and it can not produce the inspection damage of clamping process to fragile liquid crystal panel corner, liquid crystal panel can be loaded and lift its reverse side of rear detection again.
The present invention compared with prior art, has following actively useful effect:
1, the present invention can disposablely automatically complete the outward appearance of the positive inverse plate surface of liquid crystal panel is detected, and be applicable to the liquid crystal panel of various sizes, in liquid crystal panel detects, replace artificial outward appearance completely simultaneously and detect station, and detect effectively, fast the apparent all kinds of breach of liquid crystal panel, burst apart, the bad order defect such as burr, slight crack and metal erosion.
2, the present invention adopts machine vision to stablize accurate detection, guarantees the quality requirements of Liao Hou road goods, has reduced due to the caused loss of manually failing to judge simultaneously.
3, liquid crystal panel detection device provided by the present invention can make the standardization more of whole inspection operation, is also that the framework of networking from now on provides the foundation.
