Problems solved by technology

[0005] However, the above-mentioned dual-port panel inspection device has two transmission mechanisms, so it requires multiple positioning points in the height direction (that is, basically perpendicular to the transmission direction of the transmission mechanism) at the pick-and-place port and the detection port. , and the dual transmission mechanism takes up more space, and the arrangement of the mechanism is also more complicated, and each transmission mechanism needs to be equipped with at least two pairs of clamps to clamp and position the panel; thus making the panel detection device with this dual-port design High equipment cost

Embodiment Construction

[0016] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Referring to FIG. 2 , the panel detection device 100 provided by the embodiment of the present invention includes a housing 110 , a pick-and-place part 120 and a detection part 130 arranged on the housing 110 , and the A pre-clamp mechanism 122 , a detection platform 132 , a detection mechanism 134 , a buffer mechanism 136 , and a transfer mechanism 160 . The pre-clamping mechanism 122 is disposed on the pick-and-place portion 120 . The detection table 132 , the detection mechanism 134 and the buffer mechanism 136 are installed in the detection part 130 .

[0018] 3 and 4, the pre-clamping mechanism 122 can move up and down in a direction substantially perpendicular to the panel conveying direction of the conveying mechanism 160 (as shown by the double-headed arrow in FIG. 3 ), so as to move the panel to be detected Transport to th...

Abstract

The apparatus comprises: a picking and placing unit and a testing unit. It also comprises a pre clamping mechanism located at the picking and placing unit, a testing table located at the testing unit, a buffer mechanism, and a transfer mechanism. Said buffer mechanism is located at the testing unit and is used for fixturing the panel completing the test; said transfer mechanism is used for transferring untested panel clamped by the pre clamping mechanism to the testing table, and transferring back the tested panel to the picking and placing unit. The invention also reveals a method thereof.

Description

technical field [0001] The invention relates to a panel detection device and a panel detection method used in the field of flat panel display manufacturing. Background technique [0002] Usually, after the TFT-LCD cell assembly process is completed, it is necessary to use a panel inspection device (also known as a lighting tester) to check the image display status of the bonded LCD panel and whether there is any damage. Bad blemishes. The basic steps to carry out this kind of detection are: finely position the liquid crystal display panel to be tested, and set a backlight source (such as a light box) to provide illumination light source for the liquid crystal display panel; contact the liquid crystal display panel with a fine probe set (Probe Unit) Each IC signal transmission point on the display panel; then various display signals to be tested are transmitted to the liquid crystal display panel. This working process is called lighting or lighting (Light-On); Automated Opt...
