[0035] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are involved in the protection scope of the utility model.

[0036] For example, Figures 1-3As shown, the embodiment proposes a sole detection device based on a visual system, comprising:

[0037] a workbench 1;

[0038] a conveyor belt 2 arranged on the workbench 1;

[0039] a visual assembly 3 arranged on the workbench 1 and having a camera 31, the scanning end of the camera 31 facing the upper surface of the conveyor belt 2;

[0040] a guide structure 4 arranged on the workbench 1 and used for guiding the sole on the conveyor belt 2;

[0041] a controller arranged on the workbench 1 and electrically connected with the conveyor belt 2 and the camera 31;

[0042] wherein the guide structure 4 and the visual assembly 3 are arranged in sequence along the movement direction of the sole on the conveyor belt 2.

[0043] In the embodiment, the sole detection device based on the visual system comprises the workbench 1, the conveyor belt 2, the visual assembly 3, the guide structure 4 and the controller. The conveyor belt 2, the visual assembly 3 and the guide structure 4 are all arranged on the workbench 1. The conveyor belt 2 is used for conveying the sole. The guide structure 4 and the visual assembly 3 are arranged in sequence along the conveying direction of the sole. The visual assembly 3 and the conveyor belt 2 are both electrically connected with the controller. The guide structure 4 is used for guiding the sole on the conveyor belt 2, i.e. correcting the posture, so as to facilitate the more convenient viewing of the sole. When the whole device is started, the sole is placed on the conveyor belt 2. Since the placing postures of the sole are various, when the sole passes through the guide structure, the postures are consistent. This form is conducive to improving the detection efficiency of the visual assembly 3. The visual assembly 3 takes a picture of the sole. The picture is transmitted to the controller. The quality of the sole is detected in the controller according to the standard sole. The detection result is given by the controller. This detection method not only has high detection efficiency, but also ensures high detection degree.

[0044] Before the detection process, the picture of the standard sole is transmitted to the controller. The number of needles, the density of needle, the uniformity of needle and the size of shoe are set in the recognition algorithm. The sole to be detected is detected by setting a reasonable range. Once a certain value exceeds the set range, the controller gives an alarm.

[0045] Further, as shown in Figure 1 and Figure 3 the embodiment proposes that the guide structure 4 comprises:

[0046] a base 41 arranged on the workbench 1;

[0047] In addition to the layer plate 42, a gap is left between the lower surface of the base 41 and the upper surface of the conveying belt 2;

[0048] The guide plate 43 is rotatably arranged on the base 41, and the guide plate 43 is in the form of a horn.

[0049] The locking member is used to lock the guide plate 43 after rotation.

[0050] In this embodiment, the guide structure 4 includes the base 41, the layer plate 42, the guide plate 43, and the locking member. The base 41 is arranged on the workbench 1, the layer plate 42 is arranged on the base 41, and a gap is left between the lower surface of the layer plate 42 and the upper surface of the conveying belt 2. The single-layer shoe sole can pass through the gap, that is, the gap is used to separate the stacked shoe soles to avoid the stacked state of the shoe soles to be detected by the vision system. The guide plate 43 is rotatably arranged on the base 41, and the guide plate 43 is in the form of a horn. The two guide plates 43 can be freely rotated, and the two guide plates 43 are in the form of a horn. This is conducive to adjusting the posture and position of the shoe sole, facilitating the arrangement of the camera 31, reducing the sampling range of the camera 31, and improving the accuracy of the photographed photo. The locking member is arranged between the guide plate 43 and the base 41, and is used to lock the guide plate 43. When the guide plate 43 is rotated to the appropriate angle, the posture of the guide plate 43 can be kept unchanged by the locking member, so as to avoid the size of the horn changing constantly in the normal working state.

[0051] Further, as shown in Figure 1 and Figure 3 The guide structure 4 further includes a guide column 44. The guide column 44 is arranged on the base 41, the axis of the guide column 44 is arranged in the vertical direction, the end of the guide plate 43 is provided with a guide hole, and the guide column 44 is arranged in the guide hole.

The end of the guide plate 43 is provided with a guide hole, and the guide column 44 is arranged in the guide hole. The guide plate 43 is rotated relative to the base 41 by means of the guide hole and the guide column 44. The locking member is arranged between the guide column 44 and the guide plate 43, and is used to lock the guide plate 43 on the guide column 44.

[0053] Further, as shown in Figure 3As shown, the outer surface of the guide column 44 is provided with threads, and the locking member is a lock nut 45. Two lock nuts 45 are sleeved on the guide column 44 and are symmetrically arranged with respect to the center of the guide hole.

[0054] In this embodiment, in order to simplify the equipment and operation, the outer surface of the guide column 44 is provided with threads, and the locking member is a lock nut 45. Two lock nuts 45 are sleeved on the guide column 44, and the end of the guide plate 43 is located between the two lock nuts 45. By arranging two lock nuts 45, the height of the guide plate 43 with respect to the conveying belt 2 can be adjusted, and the locked state between the guide plate 43 and the guide column 44 can be achieved.

[0055] Further, as shown in the drawings, Figure 3 The guide structure 4 further comprises:

[0056] An adjusting column 46 is arranged on the base 41, and the axis of the adjusting column 46 is vertically arranged in the vertical direction. The outer surface of the adjusting column 46 is provided with threads.

[0057] An adjusting nut 47 is sleeved on the outside of the adjusting column 46.

[0058] Among them, the end of the layer plate 42 is provided with a through hole, and the layer plate 42 is sleeved on the outside of the adjusting column 46 through the through hole. The upper surface of the adjusting nut 47 contacts the lower surface of the layer plate 42.

[0059] In this embodiment, since the thicknesses of different types of soles are inconsistent, in order to improve the applicability of the entire device, the guide structure 4 further comprises an adjusting column 46 and an adjusting nut 47. The adjusting column 46 is arranged on the base 41, and the axis of the adjusting column 46 is arranged in the vertical direction, i.e., the axis of the adjusting column 46 is perpendicular to the upper surface of the workbench 1. The outer surface of the adjusting column 46 is provided with threads, the adjusting nut 47 is sleeved on the outside of the adjusting column 46, both ends of the layer plate 42 are provided with through holes, the adjusting column 46 is two and corresponds to the two through holes, and the adjusting nut 47 is two and corresponds to the adjusting column 46. The upper surface of the adjusting nut 47 contacts the lower surface of the end of the layer plate 42. In this way, the size of the gap between the guide plate 43 and the conveying belt 2 can be adjusted by the adjusting column 46 and the adjusting nut 47, and the adaptation to soles of different thicknesses can be realized.
