[0029] The embodiment of the application provides an appearance label detection device. The following are described in detail respectively.

[0030] Figure 1 The structural schematic diagram of one embodiment of the appearance label detection device provided by the embodiment of the application. Figure 2 For Figure 1 The sectional view along the direction of A-A. As Figure 1 And Figure 2As shown, the appearance label detection device 10 includes a bracket 11 and a detection assembly 12. The bracket 11 has a receiving space 111 for accommodating a product 20. The detection assembly 12 is connected to the bracket 11 and includes a drive mechanism 121 and an image acquisition component 122 located above the receiving space 111. The drive mechanism 121 is connected to the image acquisition component 122, which is used to capture an image of the surface of the underlying product 20. The drive mechanism 121 is used to drive the image acquisition component 122 to move to a position corresponding to the label on the product 20, so that the image acquisition component 122 can capture the label affixed to the surface of the product 20.

[0031] The drive mechanism 121 can be configured to drive the image acquisition component 122 to a first acquisition position, where the image acquisition component 122 in the first acquisition position can capture an image of the top side of the underlying product 20. Specifically, the image acquisition component 122 can include a camera with its image capturing direction facing downward. When the drive mechanism 121 drives the image acquisition component 122 to a position corresponding to a label affixed to the top side of the product 20, the image acquisition component 122 is in the first acquisition position and can accurately capture an image of the top side of the product 20, including the label.

[0032] It should be noted that when the image acquisition component 122 is in the first acquisition position, the image acquisition component 122 can be located directly above the label on the top side of the product 20, or it can be located diagonally above the label on the top side of the product 20. It is sufficient for the image acquisition component 122 to be able to capture the image of the label on the top side of the product 20.

[0033] In some embodiments, the appearance label detection device 10 may further include a reflective component 13, which is disposed on one side of the accommodating space 111 along a first direction X, where the first direction X forms an angle with the height direction Z of the appearance label detection device 10. The reflective component 13 is provided with a reflective surface 131 on the other side of the accommodating space 111 along the first direction X, and the reflective surface 131 is used to reflect an image of the side surface of the product 20.

[0034] Correspondingly, the driving mechanism 121 is used to drive the image acquisition component 122 to move between a first acquisition position and a second acquisition position. When the image acquisition component 122 is in the first acquisition position, it is used to acquire an image of the top side of the product 20 below; when the image acquisition component 122 is in the second acquisition position, it is used to acquire an image of the side of the product 20 reflected by the reflective surface 131.

[0035] The appearance label inspection device 10 provided in an embodiment of the present application comprises a reflective assembly 13 disposed on one side of a receiving space 111 for receiving a product 20 along a first direction X, such that the reflective assembly 13 has a reflective surface 131 facing the other side of the receiving space 111 along the first direction X for reflecting an image of the side surface of the product 20. Furthermore, a detection assembly 12 is disposed above the receiving space 111, such that a driving mechanism 121 of the detection assembly 12 drives an image acquisition component 122 to move between a first acquisition position and a second acquisition position. When the image acquisition component 122 is in the first acquisition position, it is used to acquire an image of the top side of the underlying product 20. When the image acquisition component 122 is in the second acquisition position, it is used to acquire an image of the side surface of the product 20 reflected by the reflective surface 131. In this manner, a single image acquisition component 122 can simultaneously acquire images of both the top and side surfaces of the product 20, thereby reducing the number of image acquisition components 122 in the appearance label inspection device 10 and lowering the cost of the appearance label inspection device 10.

[0036] In the embodiment of the present application, after the image acquisition component 122 captures the label images of the top and side of the product 20, the NI vision algorithm library can be applied to identify the ROI through image preprocessing, template matching, positioning coordinate system, OCR algorithm and other algorithms, so as to process the image information at different angles and obtain accurate label information.

[0037] Afterwards, the label information can be compared with the information in the database to determine whether the product model and other information are consistent, the operator can be reminded and the test results can be sent to the server for storage and archiving.

[0038] like Figure 2 As shown, the reflective surface 131 includes an upper side 1311 and a lower side 1312 distributed along the height direction Z of the appearance label detection device 10. The upper side 1311 and the lower side 1312 are distributed on opposite sides of the reflective surface 131, and the height of the upper side 1311 is higher than the height of the lower side 1312. In some embodiments, the upper side 1311 of the reflective surface 131 can be further away from the other side of the receiving space 111 relative to the lower side 1312. As a result, when the image acquisition component 122 is in the second acquisition position, the reflective surface 131 can more accurately reflect the image of the side of the product 20 to the image acquisition component 122.

[0039] In some embodiments, when the image acquisition component 122 is in the second acquisition position, the image acquisition component 122 can be located directly above the reflective surface 131, so that the image acquisition component 122 can more accurately capture the image of the side of the product 20 reflected by the reflective surface 131 of the reflective component 13.

[0040] Specifically, the upper side 1311 of the reflective surface 131 is further away from the other side of the receiving space 111 than the lower side 1312, and the angle formed between the reflective surface 131 and the first direction X is 45°. The image acquisition component 122 is a camera, and the camera's shooting direction is downward. When the image acquisition component 122 is in the second acquisition position, the reflective surface 131 is directly below the camera, allowing the camera to accurately capture the image of the side of the product 20 reflected by the reflective surface 131.

[0041] In other embodiments, when the image acquisition component 122 is in the second acquisition position, the image acquisition component 122 can also be located diagonally above the reflective surface 131 or at other positions, as long as the image acquisition component 122 can capture the image of the side of the product 20 reflected by the reflective surface 131.

[0042] In some embodiments, as Figure 1 and Figure 3 As shown, the reflective assembly 13 can be arranged on one side of the accommodating space 111 along the first direction X, and the driving mechanism 121 is used to drive the image acquisition component 122 to move along the first direction X, so that the image acquisition component 122 can quickly move between the first acquisition position and the second acquisition position.

[0043] Specifically, the driving mechanism 121 may include a first slide rail 1211 extending along the first direction X, and a first driving member 1212 connected to the first slide rail 1211. The image acquisition component 122 is directly or indirectly slidably connected to the first slide rail 1211 along the first direction X. The first driving member is directly or indirectly connected to the image acquisition component 122, and drives the image acquisition component 122 to slide relative to the first slide rail 1211 along the first direction X, thereby moving the image acquisition component 122 between the first acquisition position and the second acquisition position.

[0044] In other embodiments, the driving mechanism 121 may be configured to drive the image acquisition component 122 to swing between a first acquisition position and a second acquisition position. When the image acquisition component 122 is in the first acquisition position, the image acquisition direction of the image acquisition component 122 is downward toward the top side of the product 20. When the image acquisition component 122 is in the second acquisition position, the image acquisition direction of the image acquisition component 122 is tilted relative to the height direction Z and toward the reflective surface 131.

[0045] In some embodiments, as Figure 1 and Figure 3As shown, the driving mechanism 121 is also configured to drive the image collecting component 122 to move along the second direction Y, the first direction X, the second direction Y and the height direction Z are mutually at an angle. Thus, according to the label positions pasted on the top side and the side of the product 20, the image collecting component 122 can be driven by the driving mechanism 121 to move along the first direction X and the second direction Y, so that the image collecting component 122 can be accurately moved to the positions corresponding to the top side label and the reflecting surface 131 of the product 20.

[0046] Specifically, the driving mechanism 121 can include a second sliding rail 1213 extending along the second direction Y, and a second driving part 1214 connected with the second sliding rail 1213, the first sliding rail 1211 is directly or indirectly slidingly connected with the second sliding rail 1213 along the second direction Y, and the second driving part is directly or indirectly connected with the first sliding rail 1211 and drives the first sliding rail 1211 to slide along the second direction Y relative to the second sliding rail 1213, so as to drive the image collecting component 122 to move along the second direction Y.

[0047] In some embodiments, the containing space 111 can also be configured to contain a plurality of products 20, so that the detection assembly 12 can detect the labels on the plurality of products 20. Among them, the plurality of products 20 can be sequentially distributed along the second direction Y. Thus, by driving the image collecting component 122 to move along the second direction Y to the upper side of different products 20 by the driving assembly, the image collecting component 122 can be in different first collecting positions and second collecting positions, so as to detect the labels on different products 20.

[0048] Among them, the reflecting assembly 13 can include a plurality of reflecting surfaces 131 sequentially distributed along the second direction Y, and the plurality of reflecting surfaces 131 are configured to correspond to the plurality of products 20 one by one, and each reflecting surface is configured to reflect the image of the side of the corresponding product 20. Thus, when the image collecting component 122 is in different second collecting positions, it corresponds to different reflecting surfaces 131, so as to collect label images of the sides of different products 20.

[0049] Alternatively, the reflecting surface 131 of the reflecting assembly 13 can also extend along the second direction Y, and the reflecting surface 131 is configured to reflect the images of the sides of at least two products 20. When the image collecting component 122 is in different second collecting positions, it can correspond to different positions of the same reflecting surface 131, so as to collect label images of the sides of different products 20.

[0050] In some embodiments, as shown in Figure 1 and Figure 3 As shown, the driving assembly can also be configured to drive the image collecting component 122 to move along the height direction Z, so that the image collecting component 122 can be closer to the product 20 downward, so that the image collecting component 122 can more clearly collect the images of the top side and the side of the product 20.

[0051] Specifically, the driving mechanism 121 may include a third slide rail 1215 extending along the height direction Z, and a third driving member 1216 connected to the first slide rail 1211. The image acquisition component 122 is connected to the third slide rail 1215. The third slide rail 1215 is directly or indirectly connected to the first slide rail 1211 for sliding along the height direction Z. The third driving member is directly or indirectly connected to the third slide rail 1215 and drives the third slide rail 1215 to slide relative to the first slide rail 1211 along the height direction Z, thereby driving the image acquisition component 122 to move along the height direction Z.

[0052] In the embodiment of the present application, the first driving member 1212, the second driving member 1214, and the third driving member 1216 may be motors or their power components. The VPLC760 motion controller may be used to control the movement of the first driving member 1212, the second driving member 1214, and the third driving member 1216 to accurately move the image acquisition component 122 to a position corresponding to the label and capture the label image on the product 20.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, the appearance label detection device 10 may further include a light source 14, which is disposed in the accommodation space 111. Thus, the light source 14 can fill in the accommodation space 111 with light, so that the image acquisition component 122 can more clearly capture the label on the product 20.

[0054] Among them, the light source 14 and the reflective component 13 can be located on the same side of the accommodating space 111 to increase the brightness of the side of the product 20, thereby increasing the brightness of the image of the side of the product 20 reflected by the reflective surface 131, so that the image acquisition component 122 can capture the image of the side of the product 20 more clearly and accurately.

[0055] When the reflective component 13 includes multiple reflective surfaces 131 distributed in sequence along the second direction Y, the light source 14 can be located between two adjacent reflective surfaces 131, so that the light source 14 can better fill in the side lights of the multiple products 20, and the image acquisition component 122 can more clearly and accurately capture images of the side faces of the multiple products 20.

[0056] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
