The docking station 100 of the embodiment of the present application includes an external docking station 120, a transmission device and a transmission station 130.

[0016] The external docking station 120 is arranged on the outside of the wall, that is, the external docking station 120 is located outside the warehouse. The external docking station 120 can be used to receive cargo boxes. The external docking station 120 can transfer cargo boxes to the inside through the entrance and exit through the transmission device.

[0017] The transfer platform 130 is disposed on the inner side of the wall, that is, the transfer platform 130 is located inside the warehouse and can be used to transfer and carry cargo boxes delivered from the external docking platform 120 .

[0018] The docking station 100 of the embodiment of the present application sets its transfer station 130 in the internal area of ​​the warehouse, and only sets the external docking station 120 in the external area of ​​the warehouse, thereby reducing the occupation of the space in the external area of ​​the warehouse. The docking station 100 of the embodiment of the present application has a compact structure and occupies a small space.

[0019] In some embodiments, the docking station 100 of the embodiment of the present application further includes a partition door frame 110. The partition door frame 110 is embedded in the wall of the warehouse, and the partition door frame 110 can play a fixed support role for the docking station 100, and can also be used to divide the internal and external areas of the warehouse.

[0020] In some embodiments, the docking station 100 of the present application may further include a control system (not shown). The control system may be used to perform corresponding control on the docking station 100 .

[0021] like Figure 1 As shown, in some embodiments, the docking station 100 of the present application may also include an operation screen 151 located in the external area of ​​the warehouse. The operation screen 151 may be set on one side of the partition door frame 110, and the operation screen 151 may be used for information exchange between the docking station 100 and the operator and for operating and controlling the docking station 100.

[0022] In some embodiments, the docking station 100 of the present application may further include an alarm light 152 located in the outer area of ​​the warehouse. The alarm light 152 may be provided on the outer shell of the operation screen 151 and may be used to indicate various states of the docking station 100. The control system may control the alarm light 152 accordingly.

[0023] In some embodiments, the docking station 100 of the present application may also include a traceability camera 153 located in the outer area of ​​the warehouse. The traceability camera 153 may be set on the top of the docking station 100 and may be used to record all the in and out operation processes of the docking station 100 so as to provide traceability when an erroneous operation occurs.

[0024] In some embodiments, the transmission device of the present application may include, for example, a plurality of rollers 121 disposed on the external docking station 120 along the transmission direction, and the docking station 100 further includes a first drive motor (not shown), which may be used to drive the plurality of rollers 121 to rotate to control the entry and exit of the cargo box. The control system may control the first drive motor.

[0025] In some embodiments, a second pressure sensor (not shown) is further provided on the external docking station 120. The second pressure sensor can be provided at the four corners of the bottom of the external docking station 120, and the second pressure sensor can be used to obtain the weight of the cargo box placed on the external docking station 120.

[0026] The external docking station 120 of the embodiment of the present application is reversibly arranged in the wall of the warehouse. In some embodiments, the external docking station 120 is reversibly arranged on the partition door frame 110. The external docking station 120 has a folded state and an unfolded state, wherein: Figure 1 and Figure 2 The schematic diagram of the external docking station 120 in the unfolded state is disclosed. Figure 3 The schematic diagram of the external docking station 120 in the retracted state is disclosed. Figure 3 As shown, when the external docking station 120 is in the retracted state, the external docking station 120 is flipped inwardly and stored in the wall (for example, in the case of a partition door frame 110, it can be flipped and stored in the partition door frame 110), and the entrance 101 is closed, so that when the docking station 100 is not in use, the external docking station 120 can be retracted into the wall (for example, in the partition door frame 110), acting as a part of the wall and can be kept flush with the wall, thereby further reducing the occupation of the warehouse's external space. Figure 1 and Figure 2 As shown, when the external docking platform 120 is in the unfolded state, the external docking platform 120 can be turned outward from the wall (eg, the partition door frame 110 ) and unfolded to open the entrance 101 .

[0027] Figure 4 A partial schematic diagram of a second driving motor 161 and a sprocket device 162 for controlling the external docking station 120 to be retracted and extended according to an embodiment of the present application is disclosed. Figure 5 Revealed Figure 4 The partial schematic diagram of the external docking station 120 in the unfolded state is shown. Figure 4 and Figure 5 As shown, in some embodiments, the docking station 100 of the present application may further include a second drive motor 161 and a sprocket device 162, the sprocket of the sprocket device 162 is fixed to one side of the external docking station 120 through an axis, and the second drive motor 161 can control the external docking station 120 to freely retract and extend by driving the sprocket device 162. The control system can be used to control the second drive motor 161.

[0028] like Figure 1 As shown, a cargo box baffle 122 is also provided on one side of the external docking platform 120. The cargo box baffle 122 is used to position the cargo box when the cargo box is put into storage, and can be used as a positioning reference for the operator for the cargo box. Each time the cargo box is placed on the external docking platform 120, the cargo box must be placed close to the cargo box baffle 122.

[0029] like Figure 5 As shown, a support block 102 is provided at the bottom of the docking station 100 , and the bottom support block 102 is responsible for the load-bearing function of the entire docking station 100 .

[0030] Figure 6 The front view of the docking station 100 in one embodiment of the present application during the flipping process of the storage platform 140 is disclosed. Figure 6 As shown, in some embodiments, the docking station 100 of the present application may also include a storage table 140 for temporary storage. The storage table 140 can be used to temporarily place the cargo box when the cargo box is in and out of the warehouse to facilitate the operation of the staff. The storage table 140 is flippably arranged on one side of the external docking station 120, and the storage table 140 itself can be flipped upward and folded together with the external docking station 120.

[0031] In some embodiments, a proximity switch (not shown) is provided at the top of the entrance 101 (specifically, for example, the top of the partition door frame 110), and the proximity switch can be used to sense whether the external docking station 120 is folded into place. When the external docking station 120 is folded into place, the proximity switch can send a signal to the control system that the external docking station 120 is folded into place. When the control system receives the signal that the external docking station 120 is folded into place sensed by the proximity switch, it can control the power of the second drive motor 161 to be turned off.

[0032] In some embodiments, Figure 1 As shown, the docking station 100 of the present application also includes an anti-collision sensor 171 arranged on the outside of the wall, and the anti-collision sensor 171 is located below the external docking station 120. Before starting to use the docking station 100, the external docking station 120 needs to be unfolded, and the external docking station 120 needs to be flipped from top to bottom. At this time, it must be ensured that people are prohibited from standing on the flipping path of the external docking station 120 to prevent injuries. Therefore, the function of the anti-collision sensor 171 is to be used to sense whether there are objects or people on the flipping path of the external docking station 120. When the anti-collision sensor 171 recognizes that there are objects or people in the flipping path area of ​​the external docking station 120, a signal is sent to the control system. The control system can control the power of the second drive motor 161 to prohibit the external docking station 120 from unfolding when receiving the signal that the anti-collision sensor 171 recognizes that there are objects or people in the flipping path to prohibit the external docking station 120 from unfolding, and send a fault instruction to the alarm light 152.

[0033] The folding and unfolding method of the external docking station 120 of the present application is combined with reference to Figures 3 to 6As shown. When the external docking station 120 is folded, first flip the storage table 140 from left to right clockwise onto the external docking station 120, and then the operator clicks the fold button through the operation screen 151 to fold the external docking station 120. The folding action of the external docking station 120 is completed by the second drive motor 161 in cooperation with the sprocket device 162. After it is in place, the proximity switch on the top senses that the external docking station 120 is folded, and notifies the control system to turn off the power of the second drive motor 161. The external space after the external docking station 120 is folded can be completely released, and does not occupy any space outside the warehouse. When the external docking station 120 is unfolded, the anti-collision sensor 171 will first determine whether there are objects or personnel on its unfolding path. If there are objects or personnel, the control system will be notified to light up the alarm light 152 and terminate the unfolding action to ensure the safety of equipment and personnel. Under the condition that there is no object or person on the flipping and unfolding path of the external docking platform 120 , the control system controls the external docking platform 120 to unfold through the second driving motor 161 .

[0034] like Figure 2 As shown, in some embodiments, the docking station 100 of the present application further includes an OCR (Optical Character Recognition) camera 181 located in the internal area of ​​the warehouse. The OCR camera 181 can be used to take a picture of the product information on the cargo box transmitted to the transmission station 130 and then identify it, thereby confirming the category of the cargo box.

[0035] In a preferred embodiment, the OCR camera 181 includes two OCR cameras 181, which are respectively arranged on both sides of the transfer platform 130. Thus, the product information on the side of the cargo box can be photographed and identified from both sides of the cargo box. Therefore, no matter which side of the cargo box the product information on the cargo box is located, it can be identified by the OCR camera 181.

[0036] like Figure 2 As shown, in some embodiments, the transmission platform 130 of the present application includes a first transmission platform 131 and a second transmission platform 132 arranged along the transmission direction, wherein the first transmission platform 131 is closer to the external docking station 120 than the second transmission platform 132. The first transmission platform 131 can be used to assist in the identification of the cargo box, and the second transmission platform 132 can be used to assist the warehouse stacker to pick up the cargo box on it. Among them, the OCR camera 181 is located on both sides of the first transmission platform 131, and the OCR camera 181 can take pictures and identify the cargo information on the cargo box body transmitted to the first transmission platform 131.

[0037] In some embodiments, the docking station 100 of the present application may further include a binocular stereo camera 182 located above the first transmission platform 131. The binocular stereo camera 182 may be used to identify the size of the cargo box transmitted to the first transmission platform 131, thereby assisting in determining the category of the cargo box.

[0038] In some embodiments, the docking station 100 of the present application may further include a first pair of beam sensors 183. The first pair of beam sensors 183 are disposed on both sides of the first transfer station 131 near the external docking station 120. The first pair of beam sensors 183 may be used to sense whether the cargo box has entered a position completely transmitted inward by the power of the first transfer station 131. When the cargo box on the docking station 100 is transmitted to the position of the first pair of beam sensors 183, it can be recognized by the first pair of beam sensors 183. At this time, the position of the cargo box is completely transmitted inward by the power of the first transfer station 131. The first pair of beam sensors 183 then sends a signal to the control system indicating that the cargo box has entered a position completely transmitted inward by the power of the first transfer station 131. When the control system receives the signal from the first pair of beam sensors 183, it may control the power transmission of the transmission device of the external docking station 120 to be turned off, and then the second transfer station 132 will take over the transmission work.

[0039] Since the sizes of the cargo boxes are different, their positions are not fixed during the transmission process, which is not conducive to the recognition of the binocular stereo camera 182 and the OCR camera 181, and is not conducive to the cargo box being picked up by the stacker after entering the second transmission platform 132. Therefore, in some embodiments, a plurality of centering teeth 185 are respectively provided on both sides of the first transmission platform 131, and the plurality of centering teeth 185 can be used to clamp the cargo box from both sides to the middle so that the cargo box is in the center line of the transmission line.

[0040] In some embodiments, a first pressure sensor (not shown) is installed at the bottom of the centering teeth 185, and the first pressure sensor can be used to sense the clamping force applied to the cargo box clamped to the center line of the transmission line. When the cargo box has been clamped to the center line of the transmission line and the force continues to be applied, the first pressure sensor can sense whether the clamping force on the cargo box at this time reaches a predetermined clamping force threshold. When the clamping force sensed by the first pressure sensor reaches the predetermined clamping force threshold, a signal is sent to the control system. When the control system receives the signal from the first pressure sensor, it controls the centering teeth 185 to stop the clamping action, thereby preventing deformation of the cargo box caused by excessive clamping.

[0041] In some embodiments, the docking station 100 of the present application may further include a second pairing sensor 184. The second pairing sensor 184 is disposed on both sides of the first transmission platform 131 near the second transmission platform 132. The second pairing sensor 184 may be used to sense whether the cargo box is within the working range of the OCR camera 181, the binocular stereo camera 182, and the centering gripping gear 185. When the cargo box on the first transmission platform 131 is transmitted to the position of the second pairing sensor 184, it may be recognized by the second pairing sensor 184. At this time, the position of the cargo box is below the binocular stereo camera 182, within the photographic range of the OCR camera 181, and within the working range of the centering gripping gear 185. At this time, the second pairing sensor 184 will send a signal to the control system. When the control system receives the signal from the second pairing sensor 184, it may control the centering gripping gear 185 to clamp the cargo box, and after the clamping is completed, control the OCR and binocular stereo camera 182 to perform photographic recognition processing on the cargo box.

[0042] In some embodiments, the docking station 100 of the present application further includes an in-position sensor 186 disposed on one side of the second transfer platform 132. The in-position sensor 186 can be used to sense whether the cargo box has been completely transferred from the first transfer platform 131 to the second transfer platform 132. When the in-position sensor 186 senses the cargo box transferred from the first transfer platform 131 to the second transfer platform 132, it sends a signal to the control system. After receiving the signal from the in-position sensor 186, the control system can control the second transfer platform 132 to stop the transfer action, and notify the warehouse stacker that the cargo box is in place and can be picked up.

[0043] In some embodiments, the docking station 100 of the present application further includes a stop plate 187 disposed at the end of the second transfer station 132. The stop plate 187 can block the cargo box transferred to the second transfer station 132 and accurately locate the position of the cargo box after it stops, thereby ensuring the success rate of the stacker's picking up action.

[0044] When operating the docking station 100 of the embodiment of the present application, first unfold the external docking station 120 through the operation screen 151, and then manually unfold the storage platform 140. Before performing the warehousing operation, some cargo boxes can be placed on the storage platform 140. The first step is to randomly carry a cargo box to the external docking station 120 and close it to the cargo box baffle 122. At this time, the second pressure sensor inside the external docking station 120 senses the weight and reads its weight as one of the parameters for identifying the cargo box. After sensing its weight, the external docking station 120 starts the transmission roller 121 to transmit the cargo box into the warehouse. When the cargo box is sensed by the first counter-shooting sensor 183, the control system turns off the power of the external docking station 120, and the first transmission platform 131 continues to transmit inward. When the cargo box is sensed by the second counter-shooting sensor 184, the control system temporarily turns off the power of the first transmission platform 131. At this time, the control system controls the start of the centering teeth 185 to perform a centering clamping action on the cargo box, so that it is on the center line of the transmission line, ensuring that the cargo box can be in the correct position when it is subsequently identified, and the accuracy of the position when it is picked up by the stacker after entering the second transmission platform 132. Thereafter, the OCR cameras 181 on both sides are started to take pictures and identify the image information of the side of the cargo box, and the binocular stereo camera 182 on the top is started to identify the length, width and height of the cargo box. At this time, the control system can accurately identify the category of the cargo box through the weight information, image information, and size information that have been obtained, and match and proofread it with the cargo box category preset in the control system. The superposition of triple information can greatly improve the accuracy and fault tolerance of cargo box identification, ensuring the absolute success rate of each identification. After completing the information identification of the cargo box category, continue to start the first transfer platform 131 to transfer the cargo box to the second transfer platform 132. When the cargo box is sensed by the in-place sensor 186, it is also intercepted by the in-place baffle 187, which means that the cargo box is in place and can be taken away by the stacker later, thus completing the entire warehousing process of the cargo box.

[0045] The docking station 100 of the embodiment of the present application has a very small volume and floor space, and has a very high degree of space compactness, and is more suitable for micro warehouses, such as cold storage or freezer storage in the back kitchen of a store. At the same time, the portion of the docking station 100 outside the warehouse can be automatically folded up with one button, and does not occupy the inherent space of the back kitchen.

[0046] The docking station 100 of the embodiment of the present application can directly transport cargo boxes of different sizes and ensure that the cargo boxes always remain in a centered position during the transportation process.

[0047] The docking station 100 of the embodiment of the present application can directly identify cargo boxes of various sizes and categories, and has three different recognition modes that cooperate with each other, namely weight recognition, length, width and height size recognition, and cargo information recognition on the cargo box. The superposition of the three types of information greatly increases the error tolerance rate of category determination. Even if the OCR information recognition is damaged due to the pattern on the cargo box, the category can be judged by the weight and length, width and height dimensions of the cargo box, thereby achieving an absolute recognition success rate.

[0048] The docking station 100 of the embodiment of the present application can be directly used for direct warehousing of cargo boxes of multiple categories. At the same time, the identification of cargo box information does not require additional printing of labels on the cargo boxes or adding other identification auxiliary components. The text information, size information, and weight information on the cargo boxes can be comprehensively analyzed through multiple identification technologies to lock the cargo box category.

[0049] The docking station provided in the embodiment of the present application is described in detail above. The docking station in the embodiment of the present application is described in detail using specific examples herein. The description of the above embodiments is only used to help understand the core idea of ​​the present application and is not intended to limit the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the spirit and principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications should also fall within the scope of protection of the claims attached to the present application.
