Embodiment Construction
[0027] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.
[0028] Such as Figure 1-4 As shown, the light leakage detection device for the roll-shaped light-shielding material includes a discharging device 2, a workbench 4 and a receiving device 6 arranged in sequence. The material receiving device 6 can drive the shading material 1 to move from the side of the material discharging device 2 to the side of the material receiving device 6 and above the workbench 4 . The light leakage detection device of this embodiment further includes a detection sensor 8 and a marking mechanism 9 sequentially arranged on the workbench 4 along the traveling direction of the light-shielding material 1 .
