Light leakage detection device for roll-shaped shading material

Abstract

The invention relates to a light leakage detection device for a roll-shaped shading material. The light leakage detection device includes a material placing device, a work table and a material receiving device which are successively arranged, wherein the material receiving device can drive the shading material to march forward from the material placing device side to the material receiving device side and above the work table; the light leakage detection device also includes a detection sensor and a marking mechanism which are successively arranged on the work table along the marching direction of the shading material; the marking mechanism includes a marking head and a first driving device, wherein the marking head can move up and down in a manner of being perpendicular to the work table, and the first driving device can drive the marking head to perform reciprocating motion along the direction parallel to the marching direction of the shading material; the detection sensor can transmit a sensed position signal to a computer, the computer then sends a command to the marking mechanism, and the marking mechanism is allowed to move and mark at a corresponding position of the shading material. The light leakage detection device is suitable for the roll-shaped shading material, not only can rapidly and efficiently detect out a light leakage product, but also can determine a light leakage position and perform marking, thereby being conducive to compensation of inferior-quality products, reducing the scrapping rate of the products, and reducing the cost.

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...
