The invention provides an automatic lighting jig for a liquid crystal screen. The jig is capable of accurately putting the liquid crystal screen and a FPC (Flexible Printed Circuit) golden finger into a positioning slot and a probe guiding device through a CCD (Charge Coupled Device) visual system and a calibration square slot; the blocking self-locking of the lighting jig can be realized by controlling the motion of a fixture block along a vertical direction and the motion of a sliding lock block along a horizontal direction; a pressing device is used for pressing the probe and the FPC golden finger; after the probe is powered on, the liquid crystal screen is lightened. The self-locked jig only can unlock under the condition of horizontal movement of the sliding lock block, so that the poor contact between the FPC golden finger and the probe and even the unlocking caused by vibration in a carrying process of the jig can be avoided and the self-locking reliability and stability can be further guaranteed. The calibration square slot is directly processed on a probe guide block of the jig, so that the multi-level assembling error can be avoided; the jigs are interchangeable, so that the CCD visual system only needs to once calibrate any jig; the jigs in corresponding size can be exchanged for different products; the exchanging and production time of the equipment can be greatly shortened.
Description
technical field [0001] The invention relates to the technical field of liquid crystal screen detection, in particular to a liquid crystal screen automatic lighting fixture. Background technique [0002] After the LCD screen has been processed through multiple processes, it needs to be lit and tested to determine whether there are quality defects in the processed LCD screen. The specific process of liquid crystal screen lighting detection is: place the finished liquid crystal screen on the liquid crystal screen support, connect the FPC board (Flexible Printed Circuit, flexible circuit board) of the liquid crystal screen with the double-headed probe, and the double-headed probe is energized Afterwards, the liquid crystal screen is turned on, and the image acquisition device located above the liquid crystal screen performs image acquisition on the liquid crystal screen. If the image collected by the image acquisition device contains bright or dark points, lines, color spots, e...
