DETAILED DESCRIPTION

[0040] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0041] The first aspect of the present application provides a power supply system, which can not only realize mobile power supply to the robot, but also ensure that the power supply cables are suspended in the air without contact and friction with the ground during the movement of the robot, thereby avoiding cable wear and crushing.

[0042] See also Figure 1 as well as Figure 2 The power supply system provided in the present application includes a power distribution component 100 , a first conveying mechanism 300 and a cable 200 .

[0043] The power distribution unit 100 is an electrical device for realizing power distribution, control and protection, etc. The power distribution means that the power distribution unit 100 can distribute power from the main power supply to different power-consuming devices or circuits. In this application, the power distribution unit 100 can distribute the main power supply to the robot 500, which is also called a power distribution cabinet. The power distribution unit 100 itself belongs to the prior art, and more content can be referred to the prior art disclosure, and this application will not elaborate on it.

[0044] The first conveying mechanism 300 is used to convey a cargo box 701, such as a courier cargo box, a product cargo box, etc. The first conveying mechanism 300 includes a support member 310, a fixing member 320 and a sliding member 330, wherein the fixing member 320 is fixed to the support member 310, and the sliding member 330 is movably connected to the support member 310 along the conveying direction. One end of the cable 200 is electrically connected to the power distribution member 100, and the cable 200 has a first connection portion and a second connection portion, wherein the first connection portion is connected to the fixing member 320, and the second connection portion is connected to the sliding member 330, and the other end of the cable 200 is connected to the robot 500.

[0045] One end of the cable 200 is connected to the distribution component 100, and the first connecting part is connected to the fixing part 320. The part from one end of the cable 200 to the first connecting part is fixed. The second connecting part of the cable 200 is installed on the sliding part 330, and the sliding part 330 is slidably connected to the support part 310. Therefore, the second connecting part of the cable 200 can move back and forth along the conveying direction, so as to adapt to the robot 500 walking along the conveying direction, realize the power supply to the robot 500, and the cable will not drag on the ground, thereby protecting the cable 200.

[0046] For the convenience of introducing the present application, it is defined that the end of the cable 200 connected to the power distribution component 100 is the input end, and the end of the cable 200 connected to the robot 500 is the output end.

[0047] The first conveying mechanism 300, as a structure for conveying the cargo box 701, can be a roller conveying mechanism, which can also be called a roller conveyor line, or a belt conveying mechanism, such as a belt conveyor, which is not limited in this application. Both the roller conveying mechanism and the belt conveying mechanism are prior art and can be selected according to actual needs, and this application will not repeat them. In the case where the first conveying mechanism 300 is a roller conveying mechanism, the support member 310 can be a frame of the first conveying mechanism 300, the sliding member 330 is slidably matched with the frame, and the roller of the roller conveying mechanism is rotatably installed on the frame.

[0048] In some embodiments, see Figure 3The support member 310 may include a frame 311 and a plurality of support rods 312, the plurality of support rods 312 are connected to the frame 311, the roller is rotatably mounted on the frame 311, the plurality of support rods 312 may be arranged in two rows, the two rows of support rods 312 are sequentially arranged along the width direction of the first conveying mechanism 300, and there is a gap between the two rows of support rods 312 to form a storage space. When the sliding member 330 is close to the fixing member 320, please refer to Figure 1 , the cable 200 can be folded and stored in the storage space to save space. Of course, the cable 200 can also be located outside the storage space after being folded, and this application does not limit it.

[0049] In some embodiments, there are multiple sliding members 330, for example, three or five, and the multiple sliding members 330 are sequentially arranged along the conveying direction. The second connecting parts are the same in number as the sliding members 330 and correspond one to one. The second connecting parts are connected to the corresponding sliding members 330. The multiple sliding members 330 enable the cable 200 to adapt to a longer moving distance of the robot 500, thereby expanding the scope of application.

[0050] In a specific implementation, the support member 310 may be provided with a slide rail extending along the conveying direction, the slide rail constituting the longitudinal beam of the frame 311, and the slide member 330 slidingly cooperates with the slide rail. In other words, the slide member 330 slidingly cooperates with the longitudinal beam of the frame 311. In other embodiments, the slide rail may also be a structure separately provided on the frame 311, which is not limited in the present application.

[0051] To reduce sliding friction, see Figure 4 The sliding member 330 may include a slide 332 and a pulley 331. The pulley 331 is rotatably mounted on the slide 332, and the pulley 331 is rollingly matched with the slide rail. In order to improve the sliding stability of the sliding member 330, the number of pulleys 331 can be adjusted as needed. For example, four pulleys 331 are provided, and two pulleys 331 form a pair. In a pair of pulleys 331, one is above the upper slide rail, and the other is below the slide rail. The two slide rails clamp the slide rails, and the two pairs of pulleys 331 are relatively arranged perpendicular to the conveying direction. The above is only an enumeration. The sliding matching method of the sliding member 330 and the supporting member 310 belongs to the prior art. For more content, please refer to the prior art disclosure, and this application will not elaborate on it. During implementation, the length of the folded cable 200 can be reserved according to the bending radius of the cable 200 and the height of the slide rail.

[0052] In some embodiments, the support member 310 includes a plurality of support frames 313, and the plurality of support frames 313 are sequentially arranged along the conveying direction. The fixing member 320 is located at the support frame 313 close to the distribution member 100, and the remaining support frames 313 are all connected with a sliding member 330. Each support frame 313 can be regarded as a module. The design of the split structure can select a suitable number of support frames 313 according to the size requirements of the site, thereby expanding the scope of application. In other embodiments, the support member 310 itself can also be an integrated structure, and the connection stability is better.

[0053] In the case where the support member 310 includes multiple support frames 313, the support frame 313 located in the middle is provided with a first docking structure and a second docking structure (not numbered in the figure), and the support frames 313 located on both sides are respectively provided with a first docking structure and a second docking structure, and the first docking structure matches the second docking structure; multiple support frames 313 are matched and connected through the first docking structure and the second docking structure. The connection of multiple support frames 313 is achieved through the first docking structure and the second docking structure, so that the installation and disassembly between the support frames 313 are more convenient, and the efficiency of assembly and disassembly of the support frames 313 is improved. In the specific implementation, one of the first docking structure and the second docking structure can be a docking groove, and the other can be a docking convex, and the two docking structures are connected to each other to complete the assembly of the two support frames 313. In other embodiments, the first docking structure and the second docking structure can be docking holes respectively, and the connection of two adjacent support frames 313 is completed by inserting screws into the two docking holes.

[0054] See also Figure 1 as well as Figure 2 , the power supply system may also include a second conveying mechanism 400. Like the first conveying mechanism 300, the second conveying mechanism 400 may also convey the cargo box 701 and may be movably arranged. The cable 200 has a third connecting portion, which is connected to the second conveying mechanism 400. The second conveying mechanism 400 may be arranged as a transfer of the cable 200 and the cargo. In a specific implementation, the second conveying mechanism 400 may be arranged between the first conveying mechanism 300 and the robot 500, that is, the first connecting portion, the second connecting portion and the third connecting portion are arranged in sequence, so that the second conveying mechanism 400, as a supplement to the sliding member 330, can meet the long-distance position change requirements of the robot 500. Of course, the second conveying mechanism 400 may also be arranged between the distribution member 100 and the first conveying mechanism 300, that is, along the conveying direction, the distribution member 100, the second conveying mechanism 400, the first conveying mechanism 300 and the robot 500 are arranged in sequence, which can still meet the long-distance position change requirements of the robot 500.

[0055] In other embodiments, the power supply system can also use the second conveying mechanism 400 to replace the first conveying mechanism 300. That is to say, the power supply system includes the distribution component 100, the second conveying mechanism 400 and the cable 200. Without the first conveying mechanism 300, the transportation of the cargo box 701 and the power supply of the robot 500 can be realized. At the same time, the cable 200 is suspended in the air and not in contact with the ground, thereby protecting the cable 200.

[0056] In the case where the power supply system includes the first conveying mechanism 300 and the second conveying mechanism 400, in some embodiments, see Figure 2 The height of the second conveying mechanism 400 is lower than that of the first conveying mechanism 300, so that the second conveying mechanism 400 can be moved to the storage space of the first conveying mechanism 300 when not working, thereby improving space utilization.

[0057] In some embodiments, see Figure 1 as well as Figure 2 , a transition line 340 is provided at the output end of the first conveying mechanism 300, the upper end of the transition line 340 is connected to the first conveying mechanism 300, and the lower end is higher than the second conveying mechanism 400. The goods can be smoothly transferred from the first conveying mechanism 300 to the second conveying mechanism 400 with good stability. In some embodiments, the transition line 340 can be a transition plate or a roller line to achieve stable transportation of goods. In other embodiments, the transition line 340 can also be installed at the input end of the second conveying mechanism 400, but it should be noted that the transition line 340 and the second conveying mechanism 400 are detachably connected. When the second conveying mechanism 400 is moved to the storage space, the transition line 340 is separated from the second conveying mechanism 400 to avoid the upper end of the transition line 340 interfering with the first conveying mechanism 300 during the movement of the second conveying mechanism 400 to the storage space.

[0058] In some embodiments, see Figure 5 as well as Figure 6 The second conveying mechanism 400 includes a frame 420 and an output part 430. The frame 420 is movably arranged. Along the conveying direction, the distance between the output part 430 and the frame 420 is adjustable. The third connection part is connected to the output part 430. The distance between the output part 430 and the frame 420 is adjustable, thereby driving the position of the third connection part of the cable 200 to be adjustable, so as to meet the needs of the robot 500 for longer distance position changes.

[0059] In the case where the distance between the output part 430 and the frame 420 is adjustable, in some embodiments, the second conveying mechanism 400 may be a belt telescopic machine with a running wheel 410, the telescopic end of the belt telescopic machine is telescopically connected to the frame 420, and the telescopic end forms the output part 430. The belt telescopic machine is a highly efficient material conveying equipment, and its working principle is based on the friction between the belt and the driving roller, and the belt is driven by a motor to continuously operate, thereby realizing the conveying of materials. Its telescopic function can be realized by a belt storage device or a multi-stage telescopic frame, etc. The belt telescopic machine itself belongs to the prior art and can be selected according to actual needs. For more information, please refer to the prior art disclosure, and this application will not repeat it.

[0060] In other embodiments, the second conveying mechanism 400 may also be a folding roller line, and one end of the folding roller line forms an output portion 430, so that the length of the second conveying mechanism 400 itself can be adjusted. The folding roller line is a conveying device with a foldable function, which allows the conveying line to be folded up when not in use to save space. Generally speaking, folding roller lines are divided into manual, electric, pneumatic and semi-automatic types, mainly including a frame, rollers and a drive device. The folding roller line itself belongs to the prior art and can be selected according to actual needs. For more information, please refer to the prior art disclosure, and this application will not repeat it.

[0061] When the second conveying mechanism 400 is a telescopic belt machine with walking wheels 410, the telescopic end of the telescopic belt machine can be extended into the cargo compartment 600 to provide cargo box 701 transportation and cable 200 for the robot 500 operating in the cargo compartment 600. After the robot 500 finishes the operation, it only needs to retract to withdraw from the cargo compartment 600, thereby reducing the difficulty of operation and improving the operating efficiency.

[0062] In some embodiments, see Figure 6, the output part 430 can be provided with multiple, for example, three or five, etc., and the third connection part of the cable 200 is also provided with multiple, and multiple third connection parts are arranged in sequence along the extension direction of the cable 200, and the number of the third connection parts is the same as the number of the output parts 430, and they are arranged one by one, and the third connection parts are connected to the corresponding output parts 430. The provision of multiple output parts 430 can adapt to the cargo compartment 600 with a very deep depth, and facilitate the loading and unstacking operations of the robot 500 in the cargo compartment 600. Of course, the folding roller line can also enter the cargo compartment 600 to provide the cargo box 701 with the function of conveying and powering the robot 500, but compared with the belt telescopic machine, the unfolding and folding process of the folding roller line on the ground is more difficult, and the operation is cumbersome and time-consuming. In a specific embodiment, the third connection part can be fixed to the output part 430 by a clamp, or it can be clamped to the output part 430, and this application is not limited. The spacing between the clamps can be determined according to the telescopic stroke of the output part 430 and the cable 200. When the belt telescopic machine is in extension, the cable 200 switches from a bent storage state to a straightened state, thereby ensuring the power supply of the robot 500.

[0063] The running wheel 410 of the second conveying mechanism 400 is rotatably mounted on the frame 420. The second conveying mechanism 400 also includes a driving member, which is transmission-connected to the running wheel 410 to achieve the movement of the belt retractable mechanism. The cable 200 is electrically connected to the driving member, so that the power distribution member 100 supplies power to the second conveying mechanism 400.

[0064] In some embodiments, the power supply system also includes a third conveying mechanism (not shown in the figure), which can be extended and retracted along the conveying direction. One end of the third conveying mechanism is connected to the robot 500, and the other end is connected to the first conveying mechanism 300 or the second conveying mechanism 400.

[0065] When the robot 500 is working in the cargo compartment 600, it needs to move along the length direction of the cargo compartment 600. For example, after disassembling a row of cargo boxes 701, it needs to move forward to disassemble the next row of cargo boxes 701. At this time, the output part 430 of the second conveying mechanism 400 also needs to move forward, but the operating speeds of the two may be different. The third conveying mechanism can buffer, so that the output part 430 of the second conveying mechanism 400 and the robot 500 will not collide, and no goods will fall. The third conveying mechanism can use a telescopic roller line, that is, a folding roller line.

[0066] In some embodiments, the power supply system further includes a controller, and the controller is electrically connected to the driving member, thereby realizing automatic stopping and starting of the second conveying mechanism 400 .

[0067] The cross section of the cable 200 can be circular or elliptical. When selecting the cable 200, a flat cable 200 that can be bent at a large angle can be selected. As the position of the robot 500 inside the cargo compartment 600 changes, the cable 200 can be freely retracted. The position and number of the second connection part and the third connection part of the cable 200 are determined according to the bending angle of the cable 200, the height of the sliding member 330 and the clamp, and ensuring that the cable 200 is always in a suspended state, and there is no specific limitation.

[0068] An embodiment of the second aspect of the present application provides a cargo compartment loading and unloading system, comprising a power supply system according to any embodiment of the first aspect.

[0069] The cargo compartment loading and unloading system may further include a robot 500 , which is used for loading and unloading operations in the cargo compartment 600 , and the robot 500 is connected to the cable 200 .

[0070] The robot 500 may include a gripping arm 510 and a body 520, wherein the gripping arm 510 is rotatably connected to the body 520, and the body 520 is provided with a roller section 521 close to the second conveying mechanism 400, and the gripping arm 510 may grab the goods in the cargo compartment 600 and place them on the roller section 521, or may grab the goods on the roller section 521 and place them in the cargo box 701 for palletizing. The roller section 521 may be connected to the output end of the first conveying mechanism 300, the second conveying mechanism 400 or the third conveying mechanism.

[0071] A plug 522 is provided on the body 520 of the robot 500, and the cable 200 is connected to the plug 522. The robot 500 can be a tracked walking robot 500 or a tracked walking robot 500. Since the robot 500 belongs to the prior art, more content can be referred to the prior art disclosure, and this application will not elaborate on it.

[0072] The cargo box loading and unloading system may further include another robot, which is close to the first conveying mechanism 300 and is used to grab the cargo boxes on the production line or the cargo stack and bring them to the first conveying mechanism 300 .

[0073] The following describes the process of loading the cargo in the cargo compartment 600 by the robot 500, taking the case where the power distribution unit 100, the first conveying mechanism 300, the second conveying mechanism 400 and the robot 500 are sequentially arranged along the conveying direction, the first conveying mechanism 300 is a roller conveyor line, and the second conveying mechanism 400 is a movable belt telescopic machine as an example:

[0074] The traveling wheel 410 of the belt telescopic machine moves out of the storage space under the first conveying mechanism 300, and the robot 500 also moves toward the cargo compartment 600. The sliding member 330 also slides on the supporting member 310, and the cable 200 on the first conveying mechanism 300 gradually switches from a folded state to a straight state. The telescopic portion of the belt telescopic machine extends until it enters the cargo compartment 600, and the robot 500 also enters the cargo compartment 600, and the cable 200 on the belt telescopic machine gradually switches from a folded state to a straight state. The output end of the depalletizing device or production line places the cargo box 701 at the input end of the first conveying mechanism 300, and conveys it to the roller section 521 of the robot 500 along the first conveying mechanism 300 and the second conveying mechanism 400. The grab arm 510 of the robot 500 grabs the cargo box 701 of the roller section 521 and places it in the cargo compartment 600. When a row of cargo boxes 701 in the compartment is stacked, the robot 500 retreats a distance equal to the thickness of the cargo box 701, and the output part 430 of the second conveying mechanism 400 also retracts a length equal to the distance the robot 500 retreats, and the cargo is transported continuously until the compartment is full. After the robot 500 finishes its operation, the robot 500 retreats, and the output part 430 of the second conveying mechanism 400 retracts and moves to the storage space of the first conveying mechanism 300.

[0075] The unloading process is the reverse process of the loading process and will not be described in detail.

[0076] The power supply system and cargo compartment 600 loading and unloading system provided by the present application have at least the following advantages:

[0077] (1) Only one main power source needs to be taken from the power distribution unit 100 to supply power to the first conveying mechanism 300, and one main power source will be separated from the inside to supply power to the robot 500 through the first conveying mechanism 300. That is to say, the mobile robot 500 directly obtains power from the ground. The cable 200 is fixed on the sliding member 330 of the first conveying mechanism 300. The sliding member 330 can drive the cable 200 to slide on the support member 310 along the transportation direction, so that after the ground power distribution unit 100 obtains power, the cable 200 of the robot 500 is directly connected to supply power, so that the cable 200 is suspended in the air without rubbing against the bottom surface, thereby protecting the cable 200 and being freely retractable and adaptable to the position of the robot 500. In this way, the robot 500 is not limited by the capacity of the vehicle battery and can operate continuously for 24 hours.

[0078] (2) The sliding member 330 is slidably disposed on the supporting member 310, and the robot 500 can realize the folding and storage of the cables 200. Since there are gaps between the cables 200, heat dissipation is good and safety is high.

[0079] (3) A plurality of support frames 313 are provided, and the supporting equipment is installed later, and can also be adjusted according to the actual placement position on site, which has high flexibility.
