Embodiment 1
[0025] Such as figure 2 and image 3 As shown, this embodiment provides a detection device for battery separator paper trachoma, which includes an opaque detection box 1, which is a specific component of the light-shielding device, and the opposite first side 11 and the second side of the detection box 1 on the box body. Two side surfaces 12 corresponding positions are provided with a through hole 10, and the through hole 10 constitutes a transmission channel for the diaphragm paper to pass through; the light source 9 and the photoreceptor 8 are all arranged in the inner cavity of the detection box 1, respectively The different sides of the plane where the separator paper passes through.
[0026] In the detection device of the present embodiment, the width of the inner cavity of the detection box 1 and the width of the through hole are the same as the width of the diaphragm paper to be transported, which ensures that the section of the diaphragm paper between the two through...
Embodiment 2
[0029] Figure 4 and Figure 5 Shown is another embodiment of the detection device for battery separator paper trachoma. This embodiment also includes a closed and opaque detection box 1 around, and a first through hole 4 and a second through hole 5 are respectively opened on its opposite first side 11 and second side 12, thereby forming two supply channels. The transmission channel through which the diaphragm paper 2 passes; correspondingly, the first light source 3 and the second light source 7 are respectively arranged at both ends of the inner cavity of the detection box 1 and on each side of the two diaphragm papers 2; the photoreceptor 8 is arranged at the first transparent In the interlayer space between the hole 4 and the second through hole 5, since the photoreceptor 8 is set on the diaphragm paper during the winding process, and the winding of the two diaphragm papers is carried out synchronously, once the photoreceptor 8 Sensing the light signal passing through th...
