Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

As shown in fig. 1-2, the present invention provides a light box system for glass inspection, which comprises a light box, wherein the light box comprises a light box frame 1, a plurality of light sources 2, transparent tempered glass 3, an optical film assembly 4 and a controller 5. The lamp box frame 1 is provided with a cavity with the periphery closed and the upper part opened, the light sources 2 are distributed at the bottom of the cavity at intervals, the transparent tempered glass 3 is arranged above the cavity and covers the cavity, the optical film assembly 4 is formed on the inner surface of the transparent tempered glass 3, the controller 5 is in communication connection with the light sources 2 and is used for controlling the light sources 2 to enable each or a plurality of the light sources 2 to be lightened, and the controller 5 can be a controller matched with the lamp box or a PLC (programmable logic controller).

In a preferred embodiment, the plurality of light sources 2 is a plurality of LED lamp sets 2, each LED lamp set 2 includes a plurality of LED tubes, and each LED lamp set 2 is communicatively connected to the controller 5 through a control line 6. The LED lamp bank 2 is provided with 16 independent LED lamp banks, and 16 independent dimming control areas are formed. The controller 5 manages the 16 dimming control areas, which can perform dimming control on each dimming control area individually, or simultaneously perform dimming control on a plurality of dimming control areas, in other words, the controller 5 can control each or several of the plurality of LED lamp sets 2 to be turned on according to actual needs, thereby reducing power consumption and controlling brightness of the light source. For example, when an inspector performs a spot check on glass, the glass is found to have suspected flaws, but the entire glass is followed by the entire light source, which is intense and temporarily invisible to the naked eye. The controller can control the light source to light one or several light regulating control areas and the light contrast can expose the flaw obviously for easy, accurate and reliable inspection.
