DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 5As shown, the present invention provides an automatic bar barrel distribution system for the front and rear processes of a drawing frame, the automatic distribution system includes a drawing frame 500 and an intelligent bar barrel transportation 700, the intelligent bar barrel transportation 700 includes a barrel body 701 and a bar barrel driving machine 702 arranged at the bottom of the barrel body 701 for transporting the barrel body 701 into the drawing frame station or other processes.

[0020] Among them, the drawing machine 500 includes a turntable 502, a wireless charger 5021 is arranged in the middle of the turntable 502, the can driving machine 702 includes an electromagnetic induction charging device 7021 arranged in the can driving machine 702, and the intelligent conveying can 700 is vertically aligned with the wireless charger 5021 when it moves to the drawing machine station, and the wireless charger 5021 charges the battery of the can driving machine 702 through the electromagnetic induction charging device 7021.

[0021] The turntable 502 also includes two storage slots 5022 and a piezoelectric sensor 5023 arranged at the lowest position of the storage slots 5022. When the two wheels of the can driver 702 move into the storage slots 5022 and press on the piezoelectric sensor 5023, the turntable 502 drives the intelligent transport can 700 to rotate and wirelessly supplies power to the battery of the can driver 702.

[0022] In the present application, a can driving machine 702 and an electromagnetic induction charging device 7021 are arranged below the can, and the mobile module is integrated into the can to become a part of the can. The two are combined, and when the intelligent transport can 700 moves to the drawing machine, it can be wirelessly charged while working on the drawing machine, and the wireless charger 5021 is integrated into the turntable 502. When the intelligent transport can 700 moves to the turntable 502, when the wheel is located in the storage groove 5022 and contacts the piezoelectric sensor 5023, the wireless charger 5021 is started while controlling the rotation of the turntable 502 to charge the intelligent transport can 700 with the corresponding charging power. The charged electricity can ensure the transportation of the intelligent transport can 700 to the next process station. Therefore, the battery set on the intelligent transport can 700 does not need to use a large-capacity battery, a small-capacity battery is sufficient, and a small battery is assembled on a large number of intelligent transport cans 700, which undoubtedly greatly saves costs and improves efficiency. In addition, the mode of charging while working on the drawing frame is adopted, and there is no need to set up an additional charging station, which saves space and cost. The seamless connection between the work and charging of the intelligent conveyor can 700 is achieved, which greatly improves the benefits and work efficiency of the factory.

[0023] The automatic transportation of the intelligent conveying can 700 adopts the method of visual recognition and LORA system positioning, which is described later.

[0024] like Figure 1As shown, the automatic can distribution system also includes a first working area 100 and an N-th working area 200. The first working area 100 and the N-th working area 200 are interconnected through a can distribution channel, and the peripheries of the first working area 100 and the N-th working area 200 are isolated from the external environment by an electronic grid 300, and the opening of the electronic grid 300 leads outward to other process stations outside the drawing machine.

[0025] The consistency of the environment on the channel reduces the difficulty of machine vision recognition. The electronic grid 300 is used to control the position of the intelligent transport barrel 700, which needs to be located within the established working area and cannot be separated. When the intelligent transport barrel 700 moves near the electronic grid 300, the control terminal will make it return. The only way to leave the working area is to move to other process stations through the gap left by the electronic grid 300, and return to work after the transportation is completed. The main purpose of setting up the electronic grid 300 is to prevent the intelligent transport barrel 700 from seriously deviating from the working area during work, and then restrict all the intelligent transport barrels 700 within the working area. At the same time, the electronic grid 300 can also be set within the working area, for example, to limit the position of the position channel of the intelligent transport barrel 700, so that the empty and fully loaded intelligent transport barrels 700 can move along their respective channels respectively to avoid mutual collision, thereby improving transportation efficiency and reducing the error rate.

[0026] like Figure 1 As shown, the automatic can delivery system further includes a queuing waiting area 900 disposed between two adjacent drawing frames 500 , and the queuing waiting area 900 is used to temporarily store idle and vacant intelligent transport cans 700 .

[0027] The queuing waiting area 900 is a temporary storage point for the intelligent conveying cans 700 in the working area. When the intelligent conveying cans 700 return to the working area after completing the conveying task, and each draw frame is not in an idle state, it is transported to other queuing waiting areas 900 to wait for tasks. When the adjacent draw frame completes the current loading task, it moves out to the draw frame to work.

[0028] like Figure 1 and Figure 3 As shown, each drawing frame 500 is provided with a LORA host 600 , and each can driving machine 702 is provided with an RFID signal board 7022 , and the RFID signal board 7022 is powered by a battery of the can driving machine 702 .

[0029] The RFID signal board 7022 sends a signal to the nearby adjacent LORA host 600, and the LORA host 600 sends the signal information of the RFID signal board 7022 to the control terminal, and the control terminal uses a multi-point signal strength algorithm and a timestamp algorithm to accurately locate the position of the RFID signal board 7022.

[0030] The main purpose of setting up the LORA system is to locate the position of the smart transport can 700 in real time. When the battery and system of the smart transport can 700 are operating normally, the LORA host 600 is used to cooperate with the RFID signal board 7022 to report the position of each smart transport can 700 in real time for controlling the dispatch of the terminal. The transportation of the smart transport can 700 can be achieved through vision or laser slam. When the battery or other components of the smart transport can 700 fail, causing the smart transport can 700 to stay in or near the work area for too long, or when it is not transported according to the established route plan, it can be identified through the cooperation of the LORA host 600 and the RFID signal board 7022. During the operation of the smart transport can 700, the RFID signal board 7022 sends signals to the surrounding LORA hosts 600 at the same time interval. Due to the different distances from the smart transport can 700 and each LORA host 600, the time and signal strength of each LORA host 600 receiving the signal are different. The LORA host 600 receives the signal and sends it to the control terminal, and the control terminal uses a multi-point signal strength algorithm to analyze the location of the smart transport can 700. When the smart transport can 700 reports that its position is abnormal for a period of time, the control terminal determines that the smart transport can 700 has a fault, and then the smart transport can 700 can be taken away from the work area for on-site repair by manual or other intervention to avoid affecting the normal delivery of other smart transport cans 700.

[0031] After a single charge, the RFID signal board can maintain independent operation for 15-30 days.

[0032] like Figure 3 As shown, the automatic can delivery system also includes a towing vehicle 800 that can freely pass through the electronic grid 300. The towing vehicle 800 and the can driving machine 702 are both provided with towing hooks 7023 that can automatically dock with each other. The towing vehicle 800 is used to tow the faulty intelligent transport can 700 out of the working area for repair.

[0033] The towing vehicle 800 is used to automatically recover the faulty intelligent transport barrel 700. When it is detected that the position of the intelligent transport barrel 700 stays in one place for a long time and cannot be moved, the towing vehicle 800 can automatically recover the intelligent transport barrel 700 and wait for it to pass through the electronic grid 300 and leave the working area to avoid affecting the normal operation of other barrels. The towing vehicle 800 and the towing hook 7023 on the intelligent transport barrel 700 can complete the buckling when the towing vehicle 800 approaches the intelligent transport barrel 700, and then the towing vehicle 800 drags the intelligent transport barrel 700 to move away from the working area. The towing hook 7023 can be provided with a piezoelectric sensing device on the hook to determine whether the buckling state between the two is completed. It can be set on the inner curved edge of the hook body to detect whether an induced charge is generated during pulling. After the towing vehicle 800 determines that the buckling is completed, it drags the intelligent transport barrel 700 to move and leave the working area. If the buckling state is not completed, the towing vehicle 800 adjusts its position and re-docking until it is completed. The piezoelectric sensing device disposed on the inner bend can relatively accurately identify the buckle state without the need for complex visual recognition training.

[0034] A weight sensor is provided on the can driving machine 702 for measuring the mass of the can body 701 and determining whether the can body 701 is unloaded.

[0035] Here, the system determines whether the intelligent transport can 700 is in an empty standby state or a fully loaded transport state, and the control terminal sends a work instruction to the current intelligent transport can 700. The weight of an empty can and a fully loaded can are different. The weight sensor on the can driver 702 can determine its state according to whether its weight reaches the full load threshold, and send the information to the control terminal. The control terminal assigns the work task after receiving the full load or empty load signal. When there is no intelligent transport can 700 on the drawing machine, the idle intelligent transport can 700 in the adjacent or nearby queuing waiting area 900 is mobilized to the work station for loading.

[0036] like Figure 2 and Figure 4 As shown, a scanning camera 501 is provided inside the drawing machine 500, and a barcode 703 is attached to the body of the barrel 701. After the intelligent conveying barrel 700 moves to the turntable 502, the scanning camera 501 scans the barcode 703, identifies the size and load information of the barrel 701 and sends it to the control terminal, and the control terminal controls the wireless charger 5021 to match the appropriate charging power to the barrel driving machine 702.

[0037] Since the size specifications of the cans and the load design indicators they can carry are different, the weights of different cans after being fully loaded are also different. Therefore, the charging power of each intelligent transport can 700 is not the same, but the corresponding charging power is enabled for the intelligent transport cans 700 with different loads to optimize the battery health management plan of the intelligent transport can 700. The solution adopted in this application is to affix a bar code 703 recording the can specification information on the outer periphery of the can, and send the information to the control terminal, and the control terminal controls the wireless charger 5021 to output the appropriate charging power for the current intelligent transport can 700. If the full load of the can is large, a larger charging power is output to ensure that the electric energy is sufficient to drive the intelligent transport can 700 to and from the predetermined process stations. If the can load is small, a smaller charging power is used to maintain battery health and extend battery life. Alternatively, other suitable charging plans can be formulated according to the specification information of the can. The specific method is to be matched and optimized by the technicians in the relevant field according to the on-site environment, work requirements and cost control.

[0038] The intelligent conveyor can 700 uses vision or laser (slam) to identify the path.

[0039] The intelligent conveyor barrel 700 uses a visual path self-recognition solution to complete autonomous operation when it has sufficient power and can move to the next process station and return. When fully loaded, it moves to the next process station, and when empty and without tasks, it returns to the queue waiting area 900 to wait. The use of a visual solution can accurately identify the workspace scene and run to the specified position, and can also identify its own position and send information to the control terminal for the control terminal to allocate the next task of the intelligent conveyor barrel 700.

[0040] The working principle and use process of the present invention: A wireless charging device and a motor drive device are installed at the bottom of the can. Modification of the draw frame base: The wireless charging module is integrated into the draw frame base. The operation process is as follows: The can automatically moves to the next process station based on the process position and its own load status, using vision or laser (slam) to identify the path. When the process works in conjunction with the can base at the draw frame station, wireless power transmission can be performed through the can base charging device to provide the necessary power for the next walk. It is compatible with cans of various sizes, identifies can information, matches power charging modes for cans with different loads, optimizes energy saving, improves battery life, and shortens can operation time and equipment downtime.
