[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0060] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0061] like Figure 1 and Figure 2 As shown, the picker 100 of the embodiment of the present application includes a frame 120, a pick-up unit 100a and a plurality of information collection units 150. The pick-up unit 100a is installed on the frame 120, and includes a pick-up component 110 and a pick-up hopper 130 made of a transparent material, and the pick-up component 110 is used to take out the target goods stored on the shelf and transport them to the pick-up hopper 130. The plurality of information collection units 150 are arranged around the pick-up hopper 130, and are used to obtain preset information of the target goods located in the pick-up hopper 130.

[0062] The picker 100 of the embodiment of the present application has a plurality of information collection units 150 arranged around the pick-up hopper 130. After the pick-up component 110 delivers the target goods to the pick-up hopper 130, the plurality of information collection units 150 can timely collect the preset information of the target goods to further determine whether the target goods are the correct goods. If the target goods are the correct goods, subsequent packaging operations are performed. If the target goods are not the correct goods, they are processed as abnormal goods, thereby avoiding affecting the order processing efficiency due to the wrong goods being picked up. In addition, the picker of the embodiment of the present application includes a plurality of information collection units 150, each of which can collect the preset information of the target goods, effectively improving the success rate of the information collection unit 150 in obtaining the preset information of the goods, thereby improving the review efficiency.

[0063] It is understandable that there are many implementation methods for the information collection unit 150 to obtain the preset information of the goods. For example, the information collection unit 150 can use code scanning technology, image recognition technology, OCR (Optical Character Recognition) text recognition technology, electronic label technology, etc.

[0064] In addition, the preset information of the target goods may be commodity information, for example including but not limited to: commodity number, manufacturer code, global trade item number, production date, batch number, etc.

[0065] Next, the cargo pickup device of the present application is described by taking the information acquisition unit 150 as an image acquisition device as an example. The image acquisition device may be a camera, a digital camera, a scanner, etc. The image acquisition device may obtain preset information of the cargo through a one-dimensional code, a two-dimensional code, the appearance characteristics of the cargo, etc. on the target cargo, and the present application does not limit this.

[0066] like Figure 1 As shown, the picker 100 of the embodiment of the present application includes two pick-up components 110, and the two pick-up components 110 are arranged relatively along the left-right direction D1 of the frame 120, which can improve the picking efficiency.

[0067] The picking assembly 110 is connected to the frame 120, and the picking hopper 130 is connected to the two picking assemblies 110. Of course, in other embodiments, the picking hopper 130 can also be directly connected to the frame 120, and this application does not limit this.

[0068] like Figure 3 As shown, the pickup hopper 130 includes an inclined slide plate 132 and two vertical plates 133. The two vertical plates 133 are respectively connected to the two sides of the slide plate 132 in the width direction Dr2, and form an outlet 131 for the target goods to slide out.

[0069] The multiple information acquisition units 150 are image acquisition devices, and include a first information acquisition unit 151 , a second information acquisition unit 152 , a third information acquisition unit 153 , a fourth information acquisition unit 154 , a fifth information acquisition unit 155 and a sixth information acquisition unit 156 .

[0070] The first information collection unit 151 and the second information collection unit 152 are respectively located on both sides of the thickness direction Dr3 of the slide plate 132, and the lens surfaces of the first information collection unit 151 and the second information collection unit 152 are both facing the slide plate 132. The third information collection unit 153 and the fourth information collection unit 154 are respectively located on the side opposite to each other of the two vertical plates 133, and the lens surfaces of the third information collection unit 153 and the fourth information collection unit 154 are respectively facing the corresponding vertical plates 133. The fifth information collection unit 155 is arranged on the side where the exit 131 of the pickup hopper 130 is located, and the lens surface of the fifth information collection unit 155 faces the exit 131. The sixth information collection unit 156 is arranged on the side away from the exit 131 in the length direction Dr1 of the pickup hopper 130, and the lens surface of the sixth information collection unit 156 faces the space between the two vertical plates 133. The length direction Dr1, the width direction Dr2, and the thickness direction Dr3 are perpendicular to each other.

[0071] It can be seen that in the embodiment of the present application, information collection units 150 are arranged at both ends of the picking hopper 130 along the length direction Dr1, on both sides of the thickness direction Dr3, and on both sides of the width direction Dr2. In other words, information collection units 150 are arranged on the six sides of the picking hopper 130, so that multiple information collection units 150 basically cover the outer surface of the target goods, which significantly improves the success rate of the information collection unit 150 in obtaining the preset information of the target goods, thereby further improving the review efficiency.

[0072] It is understandable that the pickup hopper 130 is made of transparent material so that light can pass through the pickup hopper 130 , thereby preventing the pickup hopper 130 from blocking the information collection unit 150 located outside the vertical plate 133 and the bottom of the slide plate 132 and failing to obtain the preset information of the goods.

[0073] The present application does not limit the transparent material as long as light can pass through it. For example, the transparent material includes but is not limited to glass, acrylic, polycarbonate, etc.

[0074] like Figure 1 and Figure 3 As shown, the number of information collection units 150 arranged on each of the six surfaces of the pickup hopper 130 can be one or more. For example, the number of first information collection units 151 on the upper surface of the slide plate 132 is two, and the two first information collection units 151 are arranged along the width direction Dr2; the number of second information collection units 152 on the lower surface of the slide plate 132 is one; the number of third information collection units 153 and fourth information collection units 154 are both two, and the two third information collection units 153 are arranged along the thickness direction Dr3, and the two fourth information collection units 154 are arranged along the thickness direction Dr3; the number of fifth information collection units 155 is two, and the two fifth information collection units 155 are arranged along the width direction Dr2, and correspond to the positions of the two vertical plates 133 along the length direction Dr1; the number of sixth information collection units 156 is one.

[0075] The lens surface of the first information acquisition unit 151 and the lens surface of the second information acquisition unit 152 are both parallel to the slide plate 132. Since the first information acquisition unit 151 and the second information acquisition unit 152 are respectively arranged on both sides of the thickness direction Dr3 of the slide plate 132, the lens surfaces of the two information acquisition units are parallel to the slide plate 132, so that the shooting range of each information acquisition unit can cover as much of the slide plate 132 as possible, thereby improving the success rate of taking pictures.

[0076] like Figure 4As shown, the number of the third information acquisition units 153 and the number of the fourth information acquisition units 154 are both two; the lens surface of one of the third information acquisition units 153 is parallel to the corresponding vertical plate 133, and the lens surface of the other third information acquisition unit 153 presents a first target angle α1 with the corresponding vertical plate 133; the lens surface of one of the fourth information acquisition units 154 is parallel to the corresponding vertical plate 133, and the lens surface of the other fourth information acquisition unit 154 presents a second target angle α2 with the corresponding vertical plate 133.

[0077] In the embodiment of the present application, two third information acquisition units 153 are located on the outside of one of the vertical plates 133, and the shooting surfaces of the two third information acquisition units 153 are not parallel but have an angle, so that the two third information acquisition units 153 can shoot goods in different postures. For example, when the target goods fall onto the slide 132, its QR code is parallel to the vertical plate 133, and the third information acquisition unit 153 whose lens surface is parallel to the vertical plate 133 can obtain the QR code of the target goods. If there is an angle between the QR code and the vertical plate 133 when the target goods fall onto the slide 132, the third information acquisition unit 153 whose lens surface is at an angle to the vertical plate 133 can obtain the QR code of the target goods.

[0078] Similarly, the two fourth information collection units 154 are located on the outside of another vertical board 133, and the shooting surfaces of the two fourth information collection units 154 are not parallel but have an angle, so that the two fourth information collection units 154 can shoot goods in different postures. For example, when the target goods fall onto the slide 132, its QR code is parallel to the vertical board 133, and the fourth information collection unit 154 whose lens surface is parallel to the vertical board 133 can obtain the QR code of the target goods. If there is an angle between the QR code and the vertical board 133 when the target goods fall onto the slide 132, the fourth information collection unit 154 whose lens surface is at an angle with the vertical board 133 can obtain the QR code of the target goods.

[0079] like Figure 5 As shown, there are two fifth information collection units 155, the lens surfaces of the two fifth information collection units 155 are perpendicular to the slide 132, and the lens surface of each fifth information collection unit 155 presents a third target angle α3 with the length direction Dr1 of the slide 132. By designing the lens surface of the fifth information collection unit 155 to have the third target angle α3 with the length direction Dr1 of the slide 132, the arrangement position of the fifth information collection unit 155 ensures that the fifth information collection unit 155 is obliquely facing the goods without affecting the normal sliding of the goods from the exit 131, so as to improve the success rate of taking pictures.

[0080] like Figure 6As shown, the picker 100 of the embodiment of the present application can take the goods placed on the shelf 200 from the shelf 200. The picker 100 of the embodiment of the present application includes a frame 120, a pick-up hopper 130 and a pick-up assembly 110. The pick-up hopper 130 is installed on the frame 120, and the pick-up assembly 110 is connected to the frame 120. The pick-up assembly 110 is used to guide the goods to slide into the pick-up hopper 130.

[0081] The shelf 200 includes a plurality of cargo pallets 210 arranged at intervals, each cargo pallet 210 being arranged at an angle, and the cargo pallets 210 are used to support goods. A baffle 230 is provided at the end of each cargo pallet 210, and the baffle 230 is used to prevent the goods from sliding off the cargo pallet 210 due to their own gravity. A notch 211 is also provided at the end of each cargo pallet 210, and two adjacent notches 211 in adjacent cargo pallets 210 form a notch 212. A partition 220 is also provided on each cargo pallet 210, and two adjacent partitions 220 in adjacent cargo pallets 210 form a storage space, and the storage space is used to store a plurality of goods arranged side by side along the inclination direction of the cargo pallet 210. Under the action of gravity, two adjacent goods lean against each other, and the goods located at the bottom of the plurality of goods lean against the baffle 230.

[0082] When the picker 100 picks up goods, the picking component 110 moves to the bottom of the cargo plate 210, and moves from bottom to top through the notch 212, so that the picking component 110 picks up the goods at the bottom of the multiple goods, and makes the goods flip over the baffle 230 and slide to the picking component 110, and then slide through the picking component 110 into the picking hopper 130.

[0083] like Figure 7 As shown, the frame 120 includes a first crossbeam 121, two second crossbeams 122, two third longitudinal beams 123 and a back plate 124. The length direction of the first crossbeam 121 is parallel to the left-right direction D1 (the direction indicated by the arrow is left, and the reverse direction is right), the length direction of the second crossbeam 122 is parallel to the front-back direction D2 (the direction indicated by the arrow is front, and the reverse direction is rear), and the length direction of the third longitudinal beam 123 is parallel to the up-down direction D3 (the direction indicated by the arrow is up, and the reverse direction is down). The two ends of the first crossbeam 121 along the left-right direction D1 are respectively connected to the front ends of the two second crossbeams 122, and the lower ends of the two third longitudinal beams 123 are respectively connected to the rear ends of the two second crossbeams 122. The back plate 124 is connected to the two third longitudinal beams 123 and is located at the rear side of the two third longitudinal beams 123. Among them, the left-right direction D1, the front-back direction D2, and the up-down direction D3 are perpendicular to each other.

[0084] The frame 120 further includes two support beams 125 . The length direction of each support beam 125 is parallel to the up-down direction D3 , and the two support beams 125 are respectively connected to the two second cross beams 122 .

[0085] Among them, the cargo picker 100 of the embodiment of the present application includes two cargo pick-up components 110, the two cargo pick-up components 110 are symmetrically arranged along the left-right direction D1, and are respectively connected to two support beams 125, and the two cargo pick-up components 110 are also connected to the back panel 124.

[0086] The picking hopper 130 is located in a space enclosed by the first cross beam 121 and the two second cross beams 122 , and the picking hopper 130 is connected to the two picking assemblies 110 .

[0087] Of course, in other embodiments, the number of the picking assembly 110 can also be one, three or other numbers. The picking hopper 130 can be connected to the first crossbeam 121 and the second crossbeam 122 .

[0088] like Figure 7 As shown, the cargo hopper 130 has a fourth outlet 131 for cargo to slide out. The cargo picker 100 further includes an opening and closing assembly 140, which is used to open or close the fourth outlet 131.

[0089] As an example, the opening and closing assembly 140 includes a driving mechanism 141 and a door component 142, the door component 142 is movable between a first position closing the fourth outlet 131 and a second position opening the fourth outlet 131, and the driving mechanism 141 is connected to the pickup hopper 130 and is connected to the door component 142 to drive the door component 142 to move. It can be understood that by setting the opening and closing assembly 140, it is possible to control when the goods in the pickup hopper 130 slide out of the pickup hopper 130.

[0090] The door component 142 is made of a transparent material, so that the fifth information collection unit 155 can take a photo of the goods in the pickup hopper 130 through the door component 142. The transparent material may include but is not limited to glass, acrylic, polycarbonate, and the like.

[0091] It is understandable that the driving mechanism 141 can be a motor, an electric push rod, etc., and this application does not limit this.

[0092] like Figure 8 and Fig. 9 As shown, the pickup assembly 110 of the embodiment of the present application includes a ramp 111, a guide member 112, a rotating unit 113 and a motor 114. The ramp 111 has an edge 1111. The guide member 112 is connected to the ramp 111, and at least part of the guide member 112 extends out of the edge 1111; the rotating unit 113 is rotatably connected to the part of the guide member 112 extending out of the edge 1111, and is used to generate friction with the goods, so as to drive the goods to pass through the guide member 112 and slide into the ramp 111; the motor 114 is connected to the rotating unit 113, and is used to drive the rotating unit 113 to rotate.

[0093] like Figure 6As shown, when the picking component 110 of the embodiment of the present application picks up goods, the guide member 112 and at least part of the rotating unit 113 pass through the notch 212 from bottom to top, and the motor 114 drives the rotating unit 113 to rotate, and utilizes the friction between the rotating unit 113 and the goods to drive the goods through the guide member 112 and slide into the slope 111.

[0094] It can be seen that the pickup assembly 110 of the embodiment of the present application can take out the goods by rotating the rotating unit 113 and utilizing the friction force generated between the rotating unit 113 and the goods, and its pickup efficiency is significantly improved. In addition, when the goods slide into the pickup assembly 110, they are not only affected by the gravity of the goods themselves, but also by the friction force, which significantly improves the success rate of the goods sliding into the pickup assembly 110.

[0095] The slope 111 has a target angle relative to the horizontal plane, that is, the slope 111 is inclined. The slope 111 has a bottom plate 1115 and two side plates 1116. The bottom plate 1115 is connected to the two side plates 1116 on both sides along the front-to-back direction D2. The side plates 1116 can prevent the goods on the slope 111 from sliding off the side of the slope 111. The bottom plate 1115 of the slope 111 has the edge 1111.

[0096] Please continue reading Figure 8 and Fig. 9 , the rotating unit 113 includes two rotating members 1131 and an annular member 1132. For the convenience of explanation, the two rotating members 1131 are respectively defined as a first rotating member 1131a and a second rotating member 1131b. The first rotating member 1131a is connected to the output shaft of the motor 114, and the second rotating member 1131b is rotatably connected to the portion of the guide member 112 extending from the edge 1111. The annular member 1132 is arranged around the outer circumference of the two rotating members 1131, and the outer side surface of the annular member 1132 is used to generate friction with the goods. When the motor 114 is working, it drives the first rotating member 1131a to rotate, and the first rotating member 1131a drives the annular member 1132 to rotate, and then drives the second rotating member 1131b to follow. During the rotation of the annular member 1132, the outer surface of the annular member 1132 can generate friction with the goods, and then use the friction to drag the goods from the shelf 200 into the slope 111.

[0097] As an example, the inner side of the annular member 1132 has a first tooth structure, and the outer side of each rotating member 1131 has a second tooth structure, and the first tooth structure meshes with the second tooth structure. That is, in the embodiment of the present application, the rotating unit 113 is a synchronous belt structure. When the rotating unit 113 is a synchronous belt structure, the first rotating member 1131a is a synchronous wheel, the second rotating member 1131b is a driven wheel, and the annular member 1132 is a synchronous belt.

[0098] Of course, the rotating unit 113 is not limited to the synchronous belt structure. For example, in other embodiments, the rotating unit 113 includes a friction wheel and a motor. The friction wheel is rotatably connected to the portion of the guide member 112 extending from the edge 1111. The motor is connected to the friction wheel to drive the friction wheel to rotate so that the friction wheel generates friction with the cargo, thereby driving the cargo to pass through the guide member 112 and slide into the ramp 111.

[0099] Continue reading Figure 8 and Fig. 9 The bottom plate 1115 of the ramp 111 also has a slope 1112 for guiding the sliding of goods and a back side 1114 disposed opposite to the slope 1112. One side of the slope 1112 is an edge 1111, and the guide member 112 is attached to the slope 1112. The first rotating member 1131a and the motor 114 are both located on the side where the back side 1114 is located, and at least part of the second rotating member 1131b is higher than the slope 1112. In one embodiment, the motor 114 is fixedly connected to the bottom plate 1115 of the ramp 111. In other embodiments, the motor 114 can also be fixedly connected to the frame 120. The motor 114 is located on the side where the back side 1114 of the ramp 111 is located, and will not affect the sliding of goods on the slope 1112.

[0100] like Fig. 9 and Fig.10 As shown, the guide member 112 includes a connecting portion 1121 and a pair of cantilevers 1122. The connecting portion 1121 is connected to the slope 111 and fits the slope surface 1112. The pair of cantilevers 1122 is connected to the connecting portion 1121 and at least partially extends out of the edge 1111; wherein at least a portion of the rotating unit 113 is rotatably connected between the pair of cantilevers 1122.

[0101] In the embodiment of the present application, the second rotating member 1131b is rotatably connected between the pair of cantilevers 1122, and at least a portion of the annular member 1132 is located between the pair of cantilevers 1122. By rotatably arranging the second rotating member 1131b between the pair of cantilevers 1122, the stability of the rotation of the second rotating member 1131b can be improved, thereby improving the stability of the rotation of the annular member 1132, and achieving the effect of stably taking out the goods.

[0102] It can be understood that the connecting portion 1121 and the slope 111 can be a separate structure or an integrated structure.

[0103] A reinforcing portion 1124 is provided at one end of the cantilever 1122 connected to the connecting portion 1121. The reinforcing portion 1124 and the connecting portion 1121 are respectively located on both sides of the thickness direction of the slope 111, and a slot 1125 for inserting the slope 111 is formed between the reinforcing portion 1124 and the connecting portion 1121. In detail, the connecting portion 1121 is located on the side where the slope surface 1112 of the bottom plate 1115 of the slope 111 is located, and the reinforcing portion 1124 is located on the side where the back surface 1114 of the bottom plate 1115 is located. When the guide member 112 is assembled with the slope 111, the side where the edge 1111 of the slope 111 is located is inserted into the slot 1125 formed by the reinforcing portion 1124 and the connecting portion 1121.

[0104] When the goods slide onto the guide member 112, since the cantilever 1122 of the guide member 112 is suspended in the air, the cantilever 1122 may bend downward under the weight of the goods. In the embodiment of the present application, by providing the reinforcing portion 1124, the overall structural strength of the guide member 112 can be improved. When the cantilever 1122 has a tendency to bend downward, the reinforcing portion 1124 can abut against the bottom plate 1115 of the slope 111 to maintain the stability of the guide member 112.

[0105] like Fig. 9 and Fig.10 As shown, a stopper 1123 is provided at one end of each cantilever 1122 away from the connecting portion 1121 . The stopper 1123 protrudes from the cantilever 1122 along the thickness direction of the connecting portion 1121 , and the stopper 1123 protrudes to the left and downward direction to stop the goods.

[0106] like Figure 6 As shown, when the guide member 112 lifts the goods at the bottom through the notch 212 from bottom to top, the goods slide down the slope 111 under the action of their own weight and the friction between the annular member 1132 and the goods. At this time, the remaining goods will automatically move toward the baffle 230 under the action of their own weight.

[0107] In the embodiment of the present application, when the remaining goods slide down automatically on the cargo plate 210, the stopper 1123 will stop the goods before the baffle 230. After the picker 100 moves away from the notch 212, the remaining goods will continue to slide down until they are blocked by the baffle 230. In other words, after the picker 100 takes away a piece of goods, the remaining goods slide to the baffle 230 in two stages, which can shorten the sliding distance of the goods in each stage and avoid the goods from sliding out of the baffle 230 due to large inertia due to excessive sliding distance.

[0108] like Fig.11 As shown, the edge 1111 of the slope 111 has an opening 1113 , and the opening 1113 passes through the slope surface 1112 and the back surface 1114 . The annular member 1132 is movably disposed in the opening 1113 .

[0109] In the embodiment of the present application, the annular member 1132 is movably inserted into the opening 1113 of the slope 111 , which can reduce the length of the guide member 112 extending from the edge 1111 of the slope 111 , thereby saving costs and preventing the guide member 112 from forming a long cantilever structure.

[0110] It is understandable that in other embodiments, the picking component 110 can also be other structures. For example, the picking component 110 is a fork, which moves to the bottom of the cargo board 210 and moves from bottom to top through the notch 212, so that the fork picks up the bottommost cargo among multiple cargoes and makes the cargo flip over the baffle 230 and slide into the picking hopper 130.

[0111] Another aspect of the present application further provides a photo review method based on the above-mentioned pickup device, comprising:

[0112] Determine a photographing cycle having a plurality of photographing moments;

[0113] Control multiple information collection units around the pickup hopper 130 to take photos at multiple photo moments; wherein, at the same photo moment, when the number of information collection units participating in the photo taking is at least two, then among the at least two information collection units, no two information collection units are arranged relatively along the length direction Dr1, width direction Dr2 or thickness direction Dr3 of the slide plate 132 of the pickup hopper 130;

[0114] If one of the information collection units obtains the preset information of the target goods during a photo-taking cycle, the photo-taking will stop;

[0115] If multiple information collection units fail to obtain the preset information of the target goods within a photographing cycle, the next photographing cycle is executed.

[0116] In the photo review method of the embodiment of the present application, multiple information collection units take photos in sequence at multiple photo moments included in a photo cycle. In order to improve the efficiency of taking photos, at the same photo moment, the number of information collection units participating in the photo can be set to at least two, and among the at least two information collection units, there are no two information collection units that are relatively arranged along the length direction Dr1, width direction Dr2 or thickness direction Dr3 of the slide 132 of the pickup hopper 130, so as to avoid the reduction of the success rate of taking photos due to the mutual influence of light from the two relatively arranged information collection units.

[0117] For example, one photographing cycle has six photographing moments, and there is a certain time interval between adjacent photographing moments. The information collection units on the six surfaces around the pickup hopper 130 can take photos in sequence according to the six photographing moments.

[0118] As an example, the first information collection unit 151 takes a photo at the first photo moment, the second information collection unit 152 takes a photo at the second photo moment, the third information collection unit 153 takes a photo at the third photo moment, the fourth information collection unit 154 takes a photo at the fourth photo moment, the fifth information collection unit 155 takes a photo at the fifth photo moment, and the sixth information collection unit 156 takes a photo at the sixth photo moment. If the third information collection unit 153 obtains the preset information of the target goods, the subsequent information collection unit will no longer continue to perform the photo taking action for the target goods, but will control the start component 140 to open the exit 131 so that the target goods slide out from the exit 131; if within a photo cycle, none of the six information collection units obtain the preset information of the target goods, then the next photo cycle will be executed.

[0119] Of course, a photographing cycle is not limited to six photographing moments. For example, if a photographing cycle has three photographing moments, the information collection units on the six surfaces around the pickup hopper 130 need to be allocated to three photographing moments, such as two information collection units participating in photographing at each photographing moment. For example, at the first photographing moment, the information collection units on two surfaces of the pickup hopper 130 participate in photographing, such as the first information collection unit 151 participating in photographing, then the second information collection unit 152 cannot take a photo at the first photographing moment (because the second information collection unit 152 and the first information collection unit 151 are arranged opposite to each other in the thickness direction Dr3), and instead, one of the third information collection unit 153, the fourth information collection unit 154, the fifth information collection unit 155, and the sixth information collection unit 156 can take a photo at the first photographing moment. Among them, the third information collection unit 153 and the fourth information collection unit 154 cannot take a photo at the same photographing moment, and the fifth information collection unit 155 and the sixth information collection unit 166 cannot take a photo at the same photographing moment.

[0120] Of course, in another embodiment, a photographing cycle may also have two photographing moments. At the same photographing moment, there may be three information collection units participating in the photographing. For example, at the first photographing moment, the first information collection unit 151, the third information collection unit 153 and the fifth information collection unit 155 participate in the photographing; at the second photographing moment, the second information collection unit 152, the fourth information collection unit 154 and the sixth information collection unit 156 participate in the photographing.

[0121] In another embodiment, the number of information collection units participating in the photography at the two photography moments may be different. For example, a photography cycle has four photography moments. At the first photography moment, the first information collection unit 151 and the third information collection unit 153 participate in the photography. At the second photography moment, the second information collection unit 152 and the fourth information collection unit 154 participate in the photography. At the remaining two photography moments, the fifth information collection unit 155 and the sixth information collection unit 156 take photos in sequence.

[0122] The photo review method of the embodiment of the present application further includes:

[0123] If the total shooting time reaches a threshold period and multiple information collection units still have not obtained the preset information of the target goods, the shooting is stopped and the opening and closing components are controlled to open the exit 131 of the picking hopper 130 to allow the target goods to slide out of the exit, and the target goods are marked as abnormal goods.

[0124] By setting the threshold period, the total photographing time of multiple information collection units can be controlled to avoid continuous photographing due to the inability of multiple information collection units to obtain the preset information of the target goods.

[0125] It can be understood that the threshold period may include multiple photographing periods, for example, the threshold period includes two, three or four photographing periods.

[0126] In summary, the cargo pickup device and the photo verification method thereof according to the embodiment of the present application have at least the following advantages and beneficial effects:

[0127] The picker of the embodiment of the present application has multiple information collection units arranged around the pick-up hopper. After the pick-up component delivers the target goods to the pick-up hopper, the multiple information collection units can collect the preset information of the target goods in a timely manner to further determine whether the target goods are the correct goods. If the target goods are the correct goods, the subsequent packaging operation is carried out. If the target goods are not the correct goods, they are processed as abnormal goods, thereby avoiding affecting the order processing efficiency due to the wrong goods. In addition, the picker of the embodiment of the present application includes multiple information collection units, each of which can collect the preset information of the target goods, effectively improving the success rate of the information collection unit in obtaining the preset information of the goods, thereby improving the review efficiency.

[0128] In the photo review method of the embodiment of the present application, multiple information collection units take photos in sequence at multiple photo moments included in a photo cycle. In order to improve the efficiency of taking photos, at the same photo moment, the number of information collection units participating in the photo can be set to at least two, and among the at least two information collection units, there are no two information collection units that are arranged oppositely along the length direction, width direction or thickness direction of the slide plate of the pickup hopper, so as to avoid reducing the success rate of taking photos due to the mutual influence of light from the two information collection units arranged oppositely.
