[0057] Exemplary embodiments of the present application are described herein with reference to the accompanying drawings, which are meant to be exemplary. Therefore, it should be recognized that various modifications can be made to the embodiments described herein and that such modifications are intended to fall within the scope of the present application. Further, for the purpose of clarity and a concise description, descriptions of well-known functions and constructions can be omitted.

[0058] Figure 1 and Figure 4 shows a main structural schematic diagram of a face sheet identification marking system according to an embodiment of the present application. As shown in Figure 1 and Figure 4 the face sheet identification marking system can include:

[0059] a conveying mechanism 11, an image acquisition device 12, and a face sheet marking mechanism 13, wherein,

[0060] the conveying mechanism 11 is configured to convey a logistics article 20 from one location to another location, wherein the logistics article 20 has a face sheet 21 attached thereto;

[0061] the image acquisition device 12 is disposed above the conveying mechanism and is configured to acquire image information of the corresponding face sheet 21 when the logistics article 20 passes through a designated area along with the conveying mechanism 11, and the image information can be identified to determine the transportation information of the corresponding logistics article (20);

[0062] the face sheet marking mechanism 13 is disposed above the conveying mechanism 11 and is configured to mark a specific area of the corresponding face sheet 21 according to the result of the acquisition of the transportation information.

[0063] wherein the image acquisition device 12 and the face sheet marking mechanism 13 being disposed above the conveying mechanism generally means that the image acquisition device 12 and the face sheet marking mechanism 13 are located at any position in the space above the conveying mechanism, such as directly above, laterally above, e.g., left above, right above, etc.

[0064] The image acquisition device 12 and the face sheet marking mechanism 13 can be arranged on the ceiling of a room or a fixing frame 30 as shown in the drawings. Figures 1 to 4 The fixing frame 30 can be fixed to the ground or the support frame of the conveying mechanism 11 in a detachable manner.

[0065] The conveying mechanism 11 can be a conveying belt, a conveying cylinder or any other mechanism capable of conveying the logistics article from one location to another. It can be understood that, in order to clearly illustrate the functions of each mechanism or device, the schematic diagrams provided in the embodiments of the present application are illustrated by taking the conveying belt structure as an example.

[0066] The image acquisition device can be a common camera, a terminal device with a camera capable of recognizing or scanning a bar code or a two-dimensional code, or a smart camera. Correspondingly, the image information of the face sheet acquired by the image acquisition device can be recognized to determine the specific implementation manner of the corresponding logistics article transportation information. The first implementation manner can be that the image acquisition device directly recognizes the two-dimensional code or the bar code of the face sheet in the acquired image information, to acquire the transportation information corresponding to the face sheet identifier such as the waybill number from a waybill management system in the background for unified management of the waybill according to the face sheet identifier recognized from the two-dimensional code or the bar code. The second implementation manner can be that the image acquisition device sends the acquired image information to the waybill management system in the background, the waybill management system recognizes the two-dimensional code or the bar code of the face sheet included in the image information, and finds the transportation information of the logistics article corresponding to the two-dimensional code or the bar code according to the recognized result. The third implementation manner can be that the image acquisition device sends the acquired image information to the control management device, the control management device recognizes the two-dimensional code or the bar code included in the image information, and sends the waybill identifier recognized from the two-dimensional code or the bar code to the waybill management system in the background, to acquire the corresponding transportation information from the waybill management system.

[0067] It can be understood that the camera of the image acquisition device 12 can capture an image of the face sheet of the logistics article 20 pasting the set region above the conveying mechanism, so as to acquire the image information of the face sheet pasting the set region. Correspondingly, the relative position relationship between the image acquisition device 12 and the conveying mechanism 11 can be as shown in the drawings. Figure 1 Figure 4 Figure 2 Figure 3 Figure 1 Figure 4 ​​​​​As shown, the image acquisition device 12 is located directly above the conveying mechanism 11. This is because, for the image acquisition device 12 to be located directly above the conveying mechanism 11, the logistics article needs to be placed on the conveying mechanism by a person, and compared to the image acquisition device 12 being located above one side of the conveying mechanism 11, i.e. above the side, the person can more easily make the face sheet face the side with the image acquisition device 12 and make the face sheet face upward, which is convenient for operation. Meanwhile, the image acquisition device 12 being located directly above the conveying mechanism 11 can better capture or scan the face sheet with the conveying mechanism as the background during the capturing or scanning process. It should be noted that the relative position of the face sheet marking mechanism 13 and the conveying mechanism is generally consistent with the relative position of the image acquisition device 12 and the conveying mechanism.

[0068] It should be noted that the area captured or scanned by the camera of the image acquisition device 12 can meet the needs of logistics articles of different sizes or different dimensions, so as to ensure that the face sheet pasted on the logistics article can be captured or scanned.

[0069] The face sheet marking mechanism 13 described above can include any device that can mark a specific area of the face sheet, such as a device with marking ink, a device capable of emitting infrared rays, a device capable of emitting laser, etc.

[0070] The acquisition result of the transportation information generally refers to that the transportation information is acquired based on the image information. For the image information that the image acquisition device fails to acquire in time, or for the image information that the image acquisition device fails to acquire due to the face sheet facing problem, or for the case that the image information is acquired but the identification of the image information fails, the transportation information is not acquired, and there is no acquisition result of the transportation information.

[0071] According to the acquisition result of the transportation information, a feature identifier indicating that the transportation information has been acquired or determined can be sent to the face sheet marking mechanism after the transportation information is acquired.

[0072] The face sheet identification and marking system provided by the embodiment of the present application can automatically convey the logistics article through the conveying mechanism. When the logistics article passes through the set area along with the conveying mechanism, the image acquisition device arranged above the conveying mechanism acquires the image information of the face sheet pasted on the logistics article. The image information can be identified to determine the transportation information of the corresponding logistics article. The face sheet marking mechanism arranged above the conveying mechanism marks a specific area of the corresponding face sheet according to the acquisition result of the transportation information. Then, through the marking, it can be accurately known that the face sheet with the marking is identified to have the transportation information, and the face sheet without the marking is not identified to have the transportation information. Therefore, the transportation information of the waybill can be automatically managed, and the efficiency of the transportation information management of the waybill is effectively improved.

[0073] It is worth mentioning that the conveying mechanism described above can be a small conveying mechanism convenient for disassembly and installation, and the fixing support 30, the image acquisition device 12 and the like are also convenient for disassembly. Therefore, the face sheet identification marking system provided by the embodiment of the present application can be applied to a distribution center with a relatively small and scattered site. The distribution center can be an e-commerce distribution center or a simple logistics distribution center. The distribution center generally refers to a site for assigning tasks to express delivery personnel. The distribution center generally has a small site, a short lease period, and is relatively scattered. Therefore, the equipment required by the distribution center needs to have a small investment and a relatively simple structure. The equipment cost of the face sheet identification marking system provided by the embodiment of the present application is relatively low, and the structure is simple, which matches the needs of the distribution center.

[0074] In the embodiment of the present application, as shown in Figure 4 The face sheet marking mechanism 13 comprises a laser heating device 131 and a holder 132, wherein,

[0075] The laser heating device 131 is fixed to the holder 132.

[0076] The holder 132 is configured to adjust the laser emission angle of the fixed laser heating device 131 based on a received angle adjustment instruction signal.

[0077] The laser heating device 131 is configured to perform thermal printing on the thermal printing area 211 of the face sheet 21 by the emitted laser, so as to print a specific mark on the thermal printing area 211.

[0078] The laser heating device 131 can be a low-power laser heating gun.

[0079] That is, by means of the characteristics of the face sheet that can realize thermal printing, the face sheet that has been recognized by the image acquisition device is marked by the laser heating device 131. Subsequently, the unrecognized face sheet can be found based on the face sheet that has not been marked, so as to ensure the automatic management of the logistics waybill.

[0080] In the embodiment of the present application, the face sheet identification marking system described above can further comprise a light shield 14, wherein,

[0081] The image acquisition device 12 and the face sheet marking mechanism 13 are arranged in the light shield 14, so as to shield the light for the laser heating device 131 and isolate the set area for the image acquisition device 12.

[0082] The light shield 14 can be set to enable the laser heating device 131 to better achieve thermal printing. Correspondingly, the light shield can also isolate a set region for the image acquisition device to define the shooting or scanning region of the image acquisition device, to better identify and locate the physical position of the face sheet, so as to more accurately control the laser heating device 131 to ensure that the face sheet identification is successful and the laser heating device 131 can thermal print a specific mark on the face sheet.

[0083] In order to ensure the tightness of the light shielding, the above-mentioned holder 132 can also be sleeved in the light shield 14.

[0084] The light shield 14 can be detachably supported by the fixing support 30 to facilitate the installation and disassembly of the light shield.

[0085] In the process of acquiring the image information of the face sheet by the image acquisition device 12, there can be face sheets that are not identified with the transportation information. In order to facilitate the identification of the face sheets that are not identified with the transportation information, the embodiment of the present application sets the laser heating device 131 to thermal print a specific mark on the thermal printing area of the face sheet that is identified with the transportation information by the laser emitted by the laser heating device 131, so as to identify the face sheet that is successfully scanned according to the specific mark such as a circle, a square, etc. For the face sheet that is not marked with the specific mark, the transportation information is not identified, and the transportation information can be supplemented by re-scanning.

[0086] In the present application, the face sheet 21 can be as shown in Figure 5 As shown in Figure 5 The face sheet 21 can include a thermal printing area 211, a bar code area 212, and a waybill delivery information printing area 213. It is worth noting that Figure 5 The relative position relationship among the thermal printing area 211, the bar code area 212, and the waybill delivery information printing area 213 is only exemplarily shown, and the relative position relationship among the thermal printing area 211, the bar code area 212, and the waybill delivery information printing area 213 can be adjusted according to actual needs. In addition, the face sheet 21 can be made of thermal paper printing and cutting.

[0087] In the present application, the thermal printing frequency of the laser heating device 131 is consistent with the image acquisition frequency of the image acquisition device 12, or the thermal printing period of the laser heating device 131 is consistent with the face sheet period of the image acquisition device 12. The face sheet marked by the laser heating device 131 is consistent with the image information acquired by the image acquisition device 12, so as to ensure the integrity of the managed transportation information.

[0088] In addition, in order to further ensure that the marked surface sheet by the laser heating device 131 is consistent with the surface sheet on which the image information is acquired by the image acquisition device 12, the laser heating device 131 and the image acquisition device 12 are generally located on the same side of the conveying mechanism, such as both being located directly above the conveying mechanism. That is, the image acquisition device 12, the laser heating device 131 and the holder 132 are arranged directly above the conveying mechanism 11.

[0089] In the embodiment of the present application, in order to further ensure that the marked surface sheet by the laser heating device 131 is consistent with the surface sheet on which the image information is acquired by the image acquisition device 12, the relative position between the area where the identification code on the surface sheet is located and the thermal printing area is consistent with the relative position between the image acquisition device 12 and the laser heating device 131. For example, the area where the identification code is located is located at the upper left corner of the surface sheet, and the thermal printing area is located on the right side of the area where the identification code is located. Then, the laser heating device 131 is also located on the right side of the image acquisition device 12.

[0090] In the embodiment of the present application, the above-mentioned surface sheet identification marking system can further comprise a control management device 15, wherein,

[0091] The image acquisition device 12 is further used for shooting the image of the set area and sending the shot image to the control management device 15.

[0092] The control management device 15 is further used for, in the case that the image includes the logistics article 20 and the surface sheet 21, determining the second position of the surface sheet 21 in the next image acquisition cycle according to the first position of the surface sheet 21 in the image, the conveying speed of the conveying mechanism 11 and the scanning frequency or scanning period of the image acquisition device 12, and generating the control signal indicating the angle adjustment according to the second position.

[0093] It is worth mentioning that, while the control signal is provided for the laser heating device 131, the shooting signal can be synchronously sent to the image acquisition device 12, so as to ensure the synchronization of the laser heating device 131 and the image acquisition device 12.

[0094] The first position of the surface sheet 21 in the image shot by the image acquisition device 12 in the current scanning cycle, the conveying speed of the conveying mechanism 11 and the image acquisition frequency or period of the image acquisition device 12 can be used to calculate the second position of the surface sheet 21 in the next scanning cycle. The laser emission angle can be determined through the second position and the position of the laser heating device 131. Therefore, the laser heating device 131 can be adjusted to the laser emission angle in advance through the holder, so as to ensure the thermal printing of the specific mark.

[0095] It can be understood that the control management device 15 cannot obtain the image for the unrecognized face sheet, the control management device 15 will not send the control signal to the holder 132 and the laser heating device 131, and will not perform the thermal printing on the unrecognized face sheet, so that whether the face sheet is recognized can be determined according to the specific mark in the thermal printing area, and the image information of the unrecognized face sheet can be further obtained, so as to ensure the completeness and comprehensiveness of the transport information collection managed by the distribution center.

[0096] In the embodiment of the present application, the control management device 15 is further configured to convert the image position coordinates of the first position of the face sheet 21 in the image into spatial position coordinates of the set area; and determine the spatial position coordinates of the second position in the set area according to the spatial position coordinates, the conveying speed of the conveying mechanism 11, and the frequency or period of obtaining the image by the image acquisition device 12.

[0097] Since the set area and the image of the set area taken by the image acquisition device 12 are relatively fixed, the coordinates of each point in the image can be corresponded to the spatial coordinates on the set area, so that the image position coordinates of the first position of the face sheet 21 in the image can be converted into the spatial position coordinates of the set area, and in addition, the spatial coordinates of the image acquisition device 12 and the laser heating device 131 on the set area can also be determined, so that the spatial coordinates of the second position can be determined according to the spatial position coordinates, the conveying speed of the conveying mechanism 11, and the frequency or period of obtaining the image by the image acquisition device 12, so as to control the laser emission angle of the image acquisition device 12 based on the spatial coordinates of the second position.

[0098] In the embodiment of the present application, as shown in Figure 5 The face sheet 21 is further provided with three positioning blocks 214, and the three positioning blocks 214 are arranged at three vertices of the face sheet 21, so that the position of the face sheet in the image can be positioned more accurately, and the direction of the face sheet can also be positioned.

[0099] Correspondingly, the control management device 15 is further configured to identify the three positioning blocks of the face sheet 21 in the image, the three positioning blocks are arranged at the three vertices of the face sheet 21, and determine the first position of the face sheet 21 in the image according to the identified three positioning blocks.

[0100] In the embodiment of the present application, the control management device 15 is further configured to determine the direction of the face sheet 21 according to the identified three positioning blocks, determine the spatial position coordinates of the thermal printing area 211 of the face sheet 21 arranged in the next period of obtaining the image according to the direction of the face sheet 21, and generate the control signal for indicating the angle adjustment according to the spatial position coordinates of the thermal printing area 211, so as to more accurately position the thermal printing area 211 and effectively improve the accuracy of the thermal printing of the specific mark.

[0101] The control management device 15 can be a terminal such as a computer, a notebook, a tablet, a mobile phone, etc. of the distribution center, or a server arranged in the distribution center, which can be used to control and manage the image acquisition device 12 to control the image acquisition device 12 to acquire the image information of the face sheet of the logistics article, to integrate and manage the transportation information of the logistics article of the entire distribution center, to replace the manual scanning of the face sheet, and to realize the automatic management of the transportation information of the waybill of the distribution center.

[0102] In the embodiment of the present application, the light shield 14 can include four light shielding surfaces perpendicular to the horizontal plane, two of which are parallel to the conveying direction of the conveying mechanism 11, and the other two are perpendicular to the conveying direction of the conveying mechanism 11; the upper parts of each adjacent two light shielding surfaces 11 are connected, and the lower parts are separated, so that the logistics article enters the designated area from one light shielding surface perpendicular to the conveying direction of the conveying mechanism 11, and exits the designated area from the other light shielding surface perpendicular to the conveying direction of the conveying mechanism 11. This can realize light shielding while ensuring that the logistics article passes through the light shield.

[0103] In the embodiment of the present application, as shown in Figure 6 The face sheet identification marking system can further include a waybill management server 16, wherein the waybill management server 16 is used to integrate and manage the waybills managed by the plurality of control management devices 15. Through the waybill management server 16, the plurality of control management devices 15 of the plurality of distribution centers can be managed.

[0104] Figure 7 The main flowchart of the face sheet identification marking method implemented by the face sheet identification marking system of the above embodiment is shown. As shown in Figure 7 The face sheet identification marking method can include the following steps:

[0105] Step S701: conveying the logistics article from one location to another location by the conveying mechanism, wherein the logistics article is pasted with a face sheet;

[0106] Step S702: when the logistics article passes through the designated area with the conveying mechanism, acquiring the image information of the corresponding face sheet by the image acquisition device arranged above the conveying mechanism, and according to the scanning result, wherein the image information can be identified to determine the transportation information of the corresponding logistics article;

[0107] Step S703: according to the acquisition result of the transportation information, the face sheet marking mechanism marks the specific area of the corresponding face sheet.

[0108] In Figure 7In the embodiment shown, the image information of the face sheet pasted by the logistics article passing through the setting area on the conveying mechanism is acquired by the image acquisition device arranged above the conveying mechanism, so that the image information can be recognized to determine the transportation information corresponding to the logistics article, and according to the acquisition result of the transportation information, the specific area of the corresponding face sheet is marked by the face sheet marking mechanism arranged on the upper side of the conveying mechanism, so that the face sheet with the mark can be accurately known to be recognized for the transportation information, and the face sheet without the mark is not recognized for the transportation information, so as to realize the automatic management of the transportation information of the waybill, and effectively improve the transportation information management efficiency of the waybill.

[0109] In the embodiment of the present application, the marking of the specific area of the corresponding face sheet by the face sheet marking mechanism can include: the gimbal 132 included in the face sheet marking mechanism adjusts the laser emission angle of the laser heating device 131 included in the fixed face sheet marking mechanism 13 based on the received control signal indicating the angle adjustment; and the laser heating device 131 performs thermal printing on the thermal printing area 211 arranged on the face sheet 21 by the emitted laser to print a specific mark on the thermal printing area 211.

[0110] In the process of acquiring the image information of the face sheet by the image acquisition device 1, there can be image information of the face sheet that is not successfully acquired or image information that is not successfully recognized. In order to facilitate the identification of the face sheet with successfully acquired image information or the face sheet with not successfully recognized image information, the embodiment of the present application sets the laser heating device to perform thermal printing on the thermal printing area of the face sheet with the transportation information that can be recognized by the laser heating device 131, so as to print a specific mark on the thermal printing area. Therefore, the face sheet with the successfully scanned specific mark such as a circle, a square, etc. can be recognized, and the face sheet without the specific mark is not recognized for the transportation information, and the transportation information can be supplemented by re-scanning.
