Problems solved by technology

However, since the shading layer of the shading material is added later, some spraying or printing defects are unavoidable, that is, some light leakage parts will be formed on the surface of the shading material, and these light leakage parts will affect the shading effect of the shading material and reduce the yield of the shading material.

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 .

Abstract

The invention relates to a light leakage detection device for a roll-shaped shading material, which comprises a discharging device, a workbench and a receiving device arranged in sequence. Moving above, it also includes detection sensors and marking mechanisms that are arranged on the workbench in sequence along the direction of light-shielding material travel. The marking mechanism includes a marking head that can move up and down vertically on the workbench and drives the marking head to reciprocate along the direction parallel to the direction of light-shielding material travel. The first driving device, the detection sensor can transmit the sensed position signal to a computer, and the computer sends instructions to the marking mechanism, so that the marking mechanism moves and marks on the corresponding position of the light-shielding material. The light leakage detection device of the present invention is suitable for roll-shaped light-shielding materials, not only can quickly and efficiently detect light-leakage products, but also can determine the light-leakage parts and mark them, which is beneficial to fill in the gaps of defective products and reduces the scrap rate of products ,cut costs.

Description

technical field [0001] The invention relates to a light leakage detection device, in particular to a light leakage detection device for a light-shielding material. Background technique [0002] Light-shielding materials are usually realized by adding a light-shielding layer on the surface of the material, and are widely used in various industries. For example, aluminum foil printed with shading ink is a kind of shading material. However, since the light-shielding layer of the light-shielding material is added later, some spraying or printing defects are unavoidable, that is, some light leakage parts will be formed on the surface of the light-shielding material, and these light leakage parts will affect the light-shielding effect of the light-shielding material and reduce the yield of light-shielding material production. Therefore, a corresponding light leakage detection device is urgently needed. Contents of the invention [0003] The invention overcomes the disadvantage...
