[0036] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] Refer to Figure 1 and Figure 2 In this example, a device for detecting aluminum foil is disclosed, which includes a box body 10, a light strip 20, an induction strip 30 and a light-shielding plate 40. Specifically, the box body 10 is of a cuboid structure as a whole, so that the interior of the box body 10 forms a darkroom structure. On one side of the upper half of the box body 10, there is an aluminum foil inlet 11, and on the other side, there is an aluminum foil outlet 12. Among them, both the aluminum foil inlet 11 and the aluminum foil outlet 12 are strip-shaped and are both arranged in the horizontal direction.

[0039] The light strip 20 is strip-shaped, and both ends of the light strip 20 are fixed to the front side and the rear side inside the box body 10 respectively, so that the length direction of the light strip 20 is consistent with the length direction of the aluminum foil inlet 11. The light-emitting surface of the light strip 20 is arranged downward, and at the same time, the light strip 20 is relatively located above the aluminum foil inlet 11.

[0040] The induction strip 30 is arranged inside the box body 10 and is arranged in parallel with the light strip 20, and the induction strip 30 is located directly below the light strip 20. A light-shielding plate 40 is arranged between the induction strip 30 and the light strip 20. The light-shielding plate 40 completely isolates the induction strip 30 and the light strip 20. A strip-shaped light-transmitting opening 41 is arranged on the light-shielding plate 40. The light-transmitting opening 41 is located between the induction strip 30 and the light strip 20, and the length direction of the light-transmitting opening 41 is consistent with the length direction of the light strip 20.

[0041] A number of light sensors are densely arranged along the length direction of the induction strip 30 for sensing light.

[0042] Since the inside of the box body 10 is set as a darkroom, no light will penetrate. During use, the aluminum foil is threaded into the box body 10 from the aluminum foil inlet 11 on one side of the box body 10, and then the aluminum foil is pulled out from the aluminum foil outlet 12 on the other side of the box body 10. Then, the light strip 20 emits light inside the box body 10, and the light-shielding plate 40 is used to reduce the illumination range, and then the induction strip 30 below the light-shielding plate 40 is used for detection.

[0043] If there are holes in the aluminum foil to be detected, there will be a phenomenon of light leakage, which will be detected by the induction strip 30. In this technical solution, by detecting whether there are light leakage points on the aluminum foil, it is judged whether there are holes on the aluminum foil. Since the aluminum foil is moving continuously, the aluminum foil can be quickly and comprehensively detected.

[0044] In one specific example:

[0045] The detection device further includes two guide rollers 51. Both guide rollers are rotatably arranged on the inner wall of the box body 10, and the two ends of the guide roller 51 are respectively rotatably connected to the front side and the rear side in the box body 10, so that the guide roller 51 is parallel to the light strip 20.

[0046] The axes of the two guide rollers 51 are on the same horizontal plane, and the plane where the bottoms of the two guide rollers 51 are located is between the light-transmitting opening 41 and the induction strip 30.

[0047] During use, when the aluminum foil enters the box body 10 from the aluminum foil inlet 11, it bypasses the two guide rollers 51 and then passes out from the aluminum foil outlet 12. By arranging the two guide rollers 51, when the aluminum foil passes between the light-shielding plate 40 and the induction strip 30, it is in a straightened and flat state.

[0048] In another specific embodiment:

[0049] The detection device further includes two driving rollers 52 and a motor 53. All the driving rollers 52 are rotatably arranged inside the box body 10 and are all arranged parallel to the guide roller 51. One of the driving rollers 52 is arranged close to the aluminum foil inlet 11, and the top of this driving roller 52 is at the same height as the aluminum foil inlet 11. The other driving roller 52 is arranged close to the aluminum foil outlet 12, and the top of this driving roller 52 is at the same height as the aluminum foil outlet 12. One of the driving rollers 52 is coaxially arranged with the output shaft of the motor 53, and the driving roller 52 is directly driven to rotate by the motor 53.

[0050] In this embodiment, the aluminum foil enters the box body 10 from the aluminum foil inlet 11, first bypasses the driving roller 52 close to the aluminum foil inlet 11, then bypasses the two guide rollers 51, and finally bypasses the driving roller 52 close to the aluminum foil outlet 12 and then passes out from the aluminum foil outlet 12. During this process, the driving roller 52 is rotated by the motor 53 to provide a certain driving force for the movement of the aluminum foil.

[0051] In another specific embodiment:

[0052] The detection device further includes a plurality of sprockets 54, a chain 55 and a plurality of guide shafts 56. Among them, the guide shafts 56 are all rotatably arranged inside the box body 10. One of the guide shafts 56 is coaxially arranged on the output shaft of the motor 53, and all the other guide shafts 56 are located below the induction plate.

[0053] A sprocket 54 is arranged on all the guide shafts 56, all the guide rollers 51 and all the driving rollers 52, and all the sprockets 54 are linked together by the chain 55, so as to realize the rotation of all the guide shafts 56, guide rollers 51 and driving rollers 52 by the motor 53 through this structure.

[0054] In another specific embodiment:

[0055] The light-transmitting opening 41 is close to the induction strip 30, and there is a gap between the light-transmitting opening 41 and the induction strip 30 for the aluminum foil to pass through.

[0056] In another specific embodiment:

[0057] The top of the box body 10 is of an open structure and is provided with a cover body 13 of a detachable structure, which facilitates the placement of the aluminum foil. Specifically, the inside of the cover body 13 is a hollow structure, the light-shielding plate 40 is located at the bottom of the cover body 13, and the light strip 20 is located inside the cover body 13. The aluminum foil inlet 11 and the aluminum foil outlet 12 are at the same height and are located at the top of the box body 10.

[0058] The cover body 13 is rotatably arranged on the top of the box body 10, and the rotating shaft of the cover body 13, the aluminum foil inlet 11 and the aluminum foil outlet 12 are respectively located on three side walls of the box body 10.

[0059] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
