Embodiment Construction

[0019] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the description of the drawings, the same components are denoted by the same reference numerals, and thus repeated explanations are omitted.

[0020] (film production process monitor)

[0021] figure 1 The structure of the film production process monitor 100 according to the embodiment of the present invention is shown. The monitor 100 irradiates the film 1 moving in the direction A with broadband light (which is near-infrared light), detects diffusely reflected light emitted from the film 1 with the detection unit 30 , and calculates physical quantities representing characteristics of the film 1 . The monitor 100 includes a light source 10 , a diffuse reflection plate 20 , a detection unit 30 and an analysis unit 40 .

[0022] A UV light source unit 50 connected to an analysis unit 40 is provided upstream of the film production process monitor 100 in ...

Abstract

The purpose of the present invention is to ascertain film characteristics with high precision using a simpler method. A method for manufacturing film (1) using a film-manufacturing process monitor device (100), comprising: a spectrum acquisition step for radiating wideband light (L1), which is near-infrared light, from a light source (10) toward the film (1) moved in direction A to thereby receive diffused reflected light (L2) emitted from a film (1) in a light-receiving unit (30) and thereby acquire a spectrum of the diffused reflected light (L2) in a spectrum acquisition unit (40a) of an analyzer (40); and a physical value calculation step for calculating physical values related to the film (1) from the acquired spectrum of the differed reflected light (L2). Since physical values indicating the characteristics of the film (1) can be obtained by acquiring a spectrum, the characteristics of a film can be ascertained in a simple manner, and, e.g., a plurality of pieces of information can be acquired from the spectrum. Therefore, the characteristics of a film can be ascertained with higher precision.

Description

technical field [0001] The present invention relates to a film production method, a film production process monitor and a film inspection method. Background technique [0002] A known method for determining the properties of a film is to illuminate the film with light from a light source, measure the light reflected or transmitted by the film, and based on information about the intensity of the reflected or transmitted light calculate physical quantity. For example, Japanese Unexamined Patent Application Publication No. 2008-157634 describes a method based on the resulting The intensity of reflected or transmitted light is used to determine the degree of cure of the resin sheet. With this method, in order to obtain the physical quantity of a specific part of the resin sheet, it is necessary to move the infrared light emitting device and the infrared light receiving device, and repeat the process multiple times while switching between a plurality of filters having different...
