Abstract

The invention discloses a lighting fixture for a backlight source and a flaw detection device using the same, and relates to the technical field of detection of a backlight source, in order to solve the problems of many types of lighting fixtures in the prior art, a long development cycle, and high development costs. question. The lighting jig of the backlight according to the present invention includes a jig body, and the detection area for placing the backlight is arranged on the jig body; a bracket is also fixed on the jig body, and a bracket is provided on the bracket. A longitudinal adjustment rod, on which a horizontal adjustment rod is movably connected, and one end of the horizontal adjustment rod is fixed with a pressure head; the longitudinal adjustment rod can move up and down along the bracket to drive the horizontal adjustment rod Moving up and down, the horizontal adjustment rod can move forward, backward, left and right in the horizontal direction to drive the indenter to move in the detection area. The invention is mainly applied to the detection of small and medium-sized backlight sources.

Description

technical field [0001] The invention relates to the technical field of detection of backlight sources, in particular to a lighting fixture for backlight sources and defect detection equipment using the same. Background technique [0002] The backlight is a light source located behind the liquid crystal display, and its luminous effect directly affects the visual effect of the liquid crystal display. In the manufacturing process of the backlight, impurities, stains, or scratches are sometimes unavoidable. Therefore, in order to ensure the high quality of the backlight, it is necessary to carry out relevant inspections on the backlight, such as lighting detection. [0003] Specifically, the lighting detection of the backlight usually means that the gold finger on the flexible circuit board in the backlight is in close contact with the conductive sheet of the external power supply through the pressure head in the lighting fixture, so as to energize the flexible circuit board th...
