Problems solved by technology

[0006] However, no matter what kind of situation is mentioned above, the conveyor belts 91, 92 arranged at intervals all need a motor to drive respectively, and once there is a difference in the rotational speed of the two motors, the moving speeds of the two conveyor belts 91, 92 will be different. And when the sheet passes through the gap 93 from a conveyor belt 91 and touches another conveyor belt 92, since the two ends of the sheet touch the conveyor belts 91, 92 of different speeds, the sheet must have one end It will move relative to the

Embodiment Construction

[0035] In the following, the technical means adopted by the present invention to achieve the intended purpose of the invention will be further described in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0036] see figure 1 As shown, the first embodiment of the sheet material detection device of the present invention includes a conveyor belt device 10 , two cameras 51 , 52 and a light source 60 .

[0037] The aforementioned conveyor belt device 10 includes a first upper runner 11, a second upper runner 12, a third upper runner 13, a fourth upper runner 14, two middle runners 21, and two lower runners 31 , a conveyor belt 41 and a power unit; the positions of four upper runners 11, 12, 13, 14 are at the same height, the first upper runner 11, the second upper runner 12, the third upper runner 13 and the third Four upper runners 14 are arranged at intervals in sequence; the positions of these upper runners 11, 12, 13, 14 are hig...

Abstract

The invention discloses a sheet material detection device. The sheet material detection device comprises a conveyer belt device and at least one camera, wherein the conveyer belt device comprises four upper rotating wheels, at least one middle rotating wheel, at least one lower rotating wheel and a conveying belt; the conveying belt forms a gap between the second upper rotating wheel and the third rotating wheel and forms a containing space between the second and the third upper rotating wheels and the middle rotating wheel, the containing space is communicated with the gap, and a light source or the camera used for shooting the bottom surface of a sheet-shaped object is arranged in the containing space; and as the conveyer belt device only adopts single conveying belt, the moving speeds of the conveying belt at two sides of the gap are enabled to be consistent, and a phenomenon that the sheet-like object is damaged due to friction with the conveying belt owning to inconsistent speeds of the conveying belt at two sides of the gap when the sheet-like object passes through the gap is avoided.

Description

technical field [0001] The invention relates to a detection device for sheet materials. Background technique [0002] The sheet material detecting device of the prior art includes a conveyor belt and a camera, and the camera is arranged above the conveyor belt; when in use, a standard sheet is first placed on the conveyor belt, and the sheet moves along with the conveyor belt When passing through the bottom of the camera, the camera shoots the sheet and obtains a standard image, and then places the sheet to be tested on the conveyor belt, and the image is also obtained by the camera, and then the control unit sends the sheet to be tested The image is compared with the standard image to detect the length, shape and appearance of the sheet to be tested. [0003] see Figure 4 and Figure 5 As shown, however, in the following two situations, two conveyor belts 91, 92 arranged at intervals need to be used: [0004] One, when lighting is required, for example, when the sheet i...
