They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0028] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0029] like Figure 1As shown, the item information detection device of this embodiment mainly includes: an automatic conveyor mechanism 1, a support frame disposed next to the automatic conveyor mechanism 1, and multiple label readers disposed on the support frame. The automatic conveyor mechanism 1 can be a belt conveyor 11, on which the items to be sorted are placed, and the items are transported by the rotation of the belt 11. The multiple label readers are distributed at different positions on the support frame, so that the multiple label readers can scan electronic tags containing item information affixed to the items from at least two surfaces of the items. Preferably, the device of this embodiment can scan labels from multiple surfaces of the items; for example, it can scan labels from five surfaces of a box-like item, thus greatly improving the efficiency and accuracy of label scanning.

[0030] like Figure 1 As shown, the support frame in this embodiment includes a first column 21, a second column 22, and a crossbeam 23. The first column 21 and the second column 22 are arranged opposite to each other, and the crossbeam 23 is located at the top of the support frame and connects the first column 21 and the second column 22. The first column 21, the second column 22, and the crossbeam 23, when connected, form a gate-shaped support frame. The belt conveyor 11 passes between the first column 21 and the second column 22; in other words, the first column 21 and the second column 22 are located on opposite sides of the belt conveyor 11.

[0031] Combination Figure 1 and Figure 2 As shown, the multiple label readers include: at least one first label reader 31 disposed on the first column 21, at least one second label reader 32 disposed on the second column 22, and two third label readers 33 disposed on the crossbeam 23. In this embodiment, there are two first label readers 31 and two second label readers 32. Since the scanning range of each label reader is limited, multiple label readers on the same column can be distributed at intervals along the X and / or Z directions according to different illumination and scanning angles to ensure that all areas of each surface of the item can fall within the total scanning range of the label readers, further improving scanning efficiency. Specifically, the two first label readers 31 can scan the upper surface of the item and the surface facing the first column 21, the two second label readers 32 can scan the upper surface of the item and the surface facing the second column 22, and the two third label readers 33 can scan the two end faces of the item perpendicular to the conveyor belt 11.

[0032] like Figure 1 As shown, in this embodiment, the crossbeam 23 is equipped with a Z-axis drive module 4 for driving the third label reader 33 to rise and fall. For example... Figure 3 and Figure 4As shown, the Z-axis drive module 4 includes: a first mounting plate 41, a motor 42, a first gear 43, a first lead screw 44, a second gear 45, a first nut seat 46, a second mounting plate 47, and a synchronous belt 48. The first mounting plate 41 is connected to the crossbeam 23 of the bracket to support the entire Z-axis drive module 4. The housing of the motor 42 is fixedly mounted on the first mounting plate 41, and the first gear 43 is fixedly connected to the output shaft of the motor 42. The first lead screw 44 is rotatably connected to the first mounting plate 41 via bearings, and the second gear 45 is mounted on the first lead screw 44 and connected to the first gear 43 via a conveyor belt. The first nut seat 46 is connected to the first lead screw 44 and can drive the second mounting plate 47, which is connected to the first nut seat 46, to move up and down along the axial direction of the first lead screw 44, thereby enabling the third label reader 33 connected to the second mounting plate 47 to rise and fall. By adopting the above scheme, the installation height of the two third label readers 33 can be adjusted by the Z-axis drive module 4 to adjust their scanning range and improve the applicability of this detection device to items of different sizes.

[0033] like Figure 1 As shown, in this embodiment, the crossbeam 23 is also provided with a Y-axis drive module 5 for driving the Z-axis drive module 4 to move horizontally. For example... Figure 5 As shown, the Y-axis drive module 5 includes a second lead screw 51, a second nut seat 52, a guide rail 53, and a handwheel 54. The second lead screw 51 and the guide rail 53 are mounted parallel to each other on the crossbeam 23. The second nut seat 52 is movably connected to the second lead screw 51. The first mounting plate 41 of the Z-axis drive module 4 is connected to the second nut seat 52 and slidably connected to the guide rail 53. The handwheel 54 is connected to one end of the second lead screw 51. When a person rotates the handwheel 54, the second nut seat 52, along with the rotation of the second lead screw 51, can drive the entire Z-axis drive module 4 to move along the Y direction, thereby adjusting the position of the third label reader 33.

[0034] like Figure 3 and Figure 4As shown, the third label reader 33 in this embodiment is connected to the second mounting plate 47 of the Z-axis drive module 4 via a swing arm mechanism 6. Specifically, the swing arm mechanism 6 includes a first connecting rod 61, a second connecting rod 62, and a third connecting rod 63. The first connecting rod 61 is connected to the second mounting plate 47, and the second connecting rod 62 and the third connecting rod 63 are respectively hinged to both ends of the first connecting rod 61. The hinged connection allows the angle between the second connecting rod 62 and the first connecting rod 61, and the angle between the third connecting rod 63 and the first connecting rod 61, to be adjusted as needed. After being adjusted to the desired position, the second connecting rod 62 is fixed to the first connecting rod 61 by the first fixing plate 64 and the first fastener, and the third connecting rod 63 is fixed to the first connecting rod 61 by the second fixing plate 65 and the second fastener. The first fixing plate 64 is provided with a first arc-shaped hole 641, through which the first fastener passes to connect with the first connecting rod 61. Correspondingly, the second fixing plate 65 is also provided with a second arc-shaped hole for the second fastener to pass through to connect with the first connecting rod 61.

[0035] Better, such as Figure 1 As shown, the bracket in this embodiment is also equipped with at least one 3D scanning camera 7. The 3D scanning camera 7 is used to scan the outer contour of the item to determine its external dimensions, which can provide data for the sorting equipment in the subsequent process.

[0036] like Figure 1 As shown, in this embodiment, the belt 11 of the conveyor can be set to be inclined to the horizontal plane. In this way, when an item is placed on the belt 11, it can slide down to a preset position under the action of gravity, so as to ensure that the item can fall into the scanning range of the label reader and the 3D scanning camera 7.

[0037] In summary, the working process of the item information detection device in this embodiment is as follows: The item to be detected is placed on the belt 11 and automatically transported by the belt 11 conveyor. When the item runs under the support, multiple label readers on the support scan the item from multiple angles at the same time, which greatly improves the probability that the label on the item can be effectively and accurately scanned when the item passes under the door-shaped support. The 3D scanning camera 7 acquires the shape and size information of the item. This detection device transmits the acquired item information (label information and shape and size information) to the sorting device in the subsequent process to prepare for the subsequent sorting process.

[0038] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
