DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The present utility model will be further described below with reference to the drawings.

[0014] As Figure 1As shown in the figure, a movable visual inspection mechanism for a strip-shaped product 5 includes a marble base 1. A double-slider linear module 2 is arranged on the marble base 1. A 2D image detection component 3 and a 3D scanning component 4 are respectively arranged on the two sliders of the double-slider linear module 2. The 2D image detection component 3 includes a 2D detection fixing frame 31 fixedly arranged on the first slider 21. An upper lifting linear module 32 and a lower lifting linear module 33 are respectively arranged on the 2D detection fixing frame 31. An upper CCD 34 and a lower CCD 35 are respectively fixedly connected to the upper lifting linear module 32 and the lower lifting linear module 33. The upper CCD 34 and the lower CCD 35 are arranged oppositely, and a product channel 36 is formed between the upper CCD 34 and the lower CCD 35. The 3D scanning component 4 includes a 3D detection fixing frame 41 fixedly arranged on the second slider 22. A through hole 42 for the strip-shaped product 5 to pass through is arranged on the 3D detection fixing frame 41. An upper 3D camera 43, a lower 3D camera 44, a left 3D camera 45 and a right 3D camera 46 are respectively arranged on the upper, lower, left and right sides of the through hole 42 on the 3D detection fixing frame 41. The right 3D camera 46 is fixedly arranged on a transverse linear module 47. The transverse linear module 47 is fixedly designed on the 3D detection fixing frame 41. The upper 3D camera 43, the lower 3D camera 44 and the left 3D camera 45 are respectively fixedly connected to the 3D detection fixing frame 41 through a connecting plate 48.

[0015] A movable visual inspection mechanism for a strip-shaped product 5 of this solution can drive a 2D image inspection component 3 and a 3D scanning component 4 to move respectively through two sliders of a double-slider linear module 2. During inspection, the strip-shaped product 5 first passes through a product channel 36 in the 2D image inspection component 3, and the upper CCD 34 and the lower CCD 35 scan the QR code on the strip-shaped product 5 for product identification. Then the 3D scanning component 4 starts to operate, and the second slider 22 of the double-slider linear module 2 drives the entire 3D scanning component 4 to perform a complete scan along the length direction of the strip-shaped product 5. The number of scans can be several times. Four 3D cameras arranged on a 3D detection fixing frame 41 are arranged around a through hole 42, so that the top surface, bottom surface and two side surfaces of the strip-shaped product 5 can be scanned and photographed, thereby recording information such as the surface profile, flatness, and position of the strip-shaped product 5. Among them, the right 3D camera 46 is fixedly arranged on a transverse linear module 47, so that the distance between the right 3D camera 46 and the left 3D camera 45 can be adjusted according to the width of the strip-shaped product 5. After the 3D laser scanning and photographing are completed, the 2D image inspection component 3 performs visual inspection on the strip-shaped product 5 again, mainly detecting the size of the strip-shaped product 5. Among them, the upper CCD 34 and the lower CCD 35 can move up and down through an upper lifting linear module 32 and a lower lifting linear module 33, and the distance is adjusted according to the size of the strip-shaped product 5. This solution can be designed for the integration of 3D and 2D inspections of strip-shaped products 5, and the CCD distance can be conveniently adjusted according to the product size, which is convenient for visual inspection.

[0016] Preferably, the center of the through hole 42 and the center of the product channel 36 are on the same horizontal line. The purpose of this setting is to ensure that the strip-shaped product 5 can reach the position requirements of the 2D image inspection component 3 and the 3D scanning component 4 at one time without repeated position adjustment.

[0017] Preferably, a structural reinforcement plate 481 is arranged on the connecting plate 48. The structural reinforcement plate 481 can improve the structural strength of the connecting plate 48.

[0018] Preferably, a dust-proof baffle 23 is arranged on the double-slider linear module 2. The setting of the dust-proof baffle 23 can prevent foreign objects from entering the double-slider linear module 2 and prevent the first slider 21 and the second slider 22 from being blocked.

[0019] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
