[0049] like Figures 1 to 4 Shown and combined Figure 5 In an exemplary embodiment, the returned workpiece collection vehicle 100 includes a mobile carrier 1 , a receiver 2 , a driver 10 , and a communication interface 11 .

[0050] The mobile vehicle 1 can travel, and can also stop, for example. The mobile vehicle 1 can be equipped with a battery and use motor wheels.

[0051] like Figure 1 and Figure 2 As shown, the receiver 2 is provided on the mobile carrier 1. The position of the receiver 2 relative to the chassis of the mobile carrier 1 can be designed according to the receiving position of the machine (not shown). The receiver 2 is used to collect returned workpieces.

[0052] The driver 10 is electrically connected to the mobile vehicle 1 and the receiver 2. The driver 10 may include one or more integrated circuits, and can control the movement and parking of the mobile vehicle 1, and can also control the operation of the receiver 2.

[0053] The communication interface 11 is electrically connected to the driver 10. The communication interface 11 is used to receive signals for controlling the mobile carrier 1 and signals for controlling the receiver 2. The returned workpiece collection vehicle 100 of the embodiment of the present disclosure can be remotely controlled.

[0054] The returned workpiece collection vehicle 100 of the disclosed embodiment can autonomously move to its designated location to collect items without requiring human intervention. A single returned workpiece collection vehicle 100 can serve multiple machines at different locations, meeting irregular and unpredictable demand for defective items. Multiple returned workpiece collection vehicles 100 can also be used together. This disclosed embodiment saves manpower and improves production efficiency, ultimately helping to reduce costs and increase profits.

[0055] In some embodiments, the returned workpiece collection vehicle 100 further includes a basket feeder 4. The basket feeder 4 is disposed on the mobile carrier 1 and electrically connected to the driver 10. For example, the basket feeder 4 is disposed on the mobile carrier 1, and the receiver 2 is disposed on the basket feeder 4. The receiver 2 and the basket feeder 4 can be disposed within the same vehicle body (not shown), with the receiver 2 positioned above the basket feeder 4 along the Z-axis.

[0056] The basket feeder 4 delivers empty baskets. The receiver 2 collects returned workpieces from at least one other basket. The communication interface 11 receives signals to control the basket feeder 4. The returned workpiece collection vehicle 100 can swap baskets for the machine; if the machine has sufficient spare baskets, a basket may not be delivered. The basket collected by the receiver 2 can be full or partially full.

[0057] As shown in the figure, the receiver 2 and the basket feeder 4 can be basically the same mechanism. The receiver 2 has two tracks arranged at intervals along the X-axis direction, such as conveyor belts. The receiver 2 can transport the basket to its upper side along the Y-axis direction and keep it lifted. The basket feeder 4 can transport the basket out of the returned workpiece collection vehicle 100 along the Y-axis direction. A photoelectric sensor, for example, can be set between the two belt tracks of the receiver 2 to identify whether there is a basket. Figure 2 , the receiver 2 includes a motor for controlling the rotation of the belt.

[0058] In some embodiments, the returned workpiece collection vehicle 100 further includes a gripper 3. The gripper 3 is positioned on the receiver 2. When a basket feeder 4 is provided, the returned workpiece collection vehicle 100 may include another gripper 3 positioned at a corresponding position on the basket feeder 4. The gripper 3 includes two holding bars positioned opposite each other along the X-axis. Each holding bar can hold the basket in the X-direction, preventing the basket from moving and falling during travel. The gripper also helps position the basket for accurate delivery.

[0059] In some embodiments, the returned workpiece collection vehicle 100 further includes a display 5. The display 5 is disposed outside the receiver 2. The display 5 is electrically connected to the driver 10 and may include a colored light strip, such as a three-color light strip, to display the working status of the returned workpiece collection vehicle 100.

[0060] In some embodiments, the returned workpiece collection vehicle 100 further includes a radar 6. The radar 6 may be a laser radar. The radar 6 is connected to the mobile vehicle 1, for example, installed in front of the mobile vehicle 1 along the direction of travel. The radar 6 may also be arranged at a position higher than the mobile vehicle 1 to avoid being excessively blocked by the mobile vehicle 1 along the XY plane. The radar 6 is used to obtain external environment information of the returned workpiece collection vehicle 100, which can help to construct a contour map of objects around the running route (or Simultaneous Localization and Mapping), and can be used to update the SLAM map. The radar 6 is electrically connected to the communication interface 11. The radar 6 can be used to sense information such as the shape, distance, and obstacles of the surrounding environment during the travel of the returned workpiece collection vehicle 100, thereby helping the returned workpiece collection vehicle 100 to make appropriate decisions and actions.

[0061] In some embodiments, the returned workpiece collection vehicle 100 includes a visual sensor 7. The visual sensor 7 is positioned on the mobile vehicle 1, for example, in front of the vehicle in the direction of travel. The visual sensor 7 can be, for example, a camera. The visual sensor 7 is electrically connected to the driver 10 and is used to obtain distance information between the mobile vehicle 1 and obstacles, enabling the vehicle to determine the distance and promptly decelerate or stop the vehicle.

[0062] For example, the returned workpiece collection vehicle 100 includes a first emergency stop button 8 . The first emergency stop button 8 is located on the mobile vehicle 1, for example, at the front of the vehicle in the direction of travel. The first emergency stop button 8 is electrically connected to the driver 10 ; when triggered, the first emergency stop button 8 stops the movement of the mobile vehicle 1 . This can be triggered, for example, by an obstacle, or manually by actuating the button to bring the returned workpiece collection vehicle 100 to an emergency stop in the event of a malfunction.

[0063] Exemplarily, the returned workpiece collection vehicle 100 includes at least one second emergency stop button 9. The second emergency stop button 9 is provided on the receiver 2. The second emergency stop button 9 is electrically connected to the driver 10 to stop the receiver 2 from working when triggered. Figure 1 and Figure 3 Second emergency stop buttons 9 can be provided at both sides of the receiver 2, front and rear, to stop the receiver 2 in an emergency.

[0064] refer to Figure 4 Receiver 2 can be fixed to mobile vehicle 1. In addition to traveling along the Y-axis, mobile vehicle 1 can also turn and rotate in place to adjust its orientation within the XY plane. The center of rotation of returned workpiece collection vehicle 100 can be substantially located at the centroid, and receiver 2 can have a centrally symmetrical shape.

[0065] refer to Figure 5 and Figure 6 , the returned workpiece collection vehicle 100 provided in the embodiment of the present disclosure can be used as a terminal in the production workshop 300. The driver 10 of the returned workpiece collection vehicle 100 can be a processor, and the returned workpiece collection vehicle 100 also includes a memory, an input / output interface (Input / Output, referred to as I / O), a display 5 and an input device. The input device may include, for example, a radar 6, a visual sensor 7, an emergency stop button, etc. The driver 10, the memory and the input / output interface are connected through a system bus, and the communication interface 11, the display 5 and the input device are connected to the system bus through the input / output interface. The memory of the returned workpiece collection vehicle 100 may include a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The input / output interface of the returned workpiece collection vehicle 100 is used to exchange information between the driver 10 and external devices. The communication interface 11 is used to communicate with an external terminal or production control device 200 via wired or wireless communication. The wireless communication can be implemented via Wi-Fi, a mobile cellular network, NFC (near-field communication), a 5G network, or other technologies. When executed by the driver 10, the computer program enables the planned movement of the mobile vehicle 1, the receiving step of the package receiver 2, and the delivery step of the basket delivery device 4.

[0066] refer to Figure 6, the terminal communicates with the production control device 200 through the network. The data storage system can store the data that the production control device 200 needs to process. The data storage system can be integrated on the production control device 200, or it can be placed on the cloud or other network servers. The terminal includes a returned workpiece collection vehicle 100, a machine, a feeding vehicle for production, a collection area for reworked pieces, and may also include a personal computer, a laptop computer, a smart phone, a tablet computer, an Internet of Things device, and a portable wearable device used by the operator. The production control device 200 acts as a server, which can be implemented as an independent server or a server cluster consisting of multiple servers.

[0067] refer to Figure 7 The present disclosure provides a production control device 200. The production control device 200 may be a computer device comprising a processor 201, a memory 202, an input / output interface, and a communication interface. Exemplarily, the communication interface is a second communication interface, and the communication interface 11 of the returned workpiece collection vehicle 100 is referred to as a first communication interface.

[0068] The processor 201, memory 202, and input / output interface are connected via a system bus, and the communication interface is connected to the system bus via the input / output interface. The processor 201 of the production control device 200 is used to provide computing and control capabilities. The memory 202 includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores an operating system, computer programs, and databases. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage medium.

[0069] Illustratively, the database of the production control device 200 is used to store map data of the production workshop 300, including contour maps of objects surrounding the route, routes of feeder vehicles throughout the factory, and other data. It may also include data such as machine types and types of returned workpiece collection vehicles 100. In some embodiments, the operating system includes an MCS scheduling system and an AGV scheduling system. Illustratively, the MCS scheduling system and the AGV scheduling system are executed by different processors 201.

[0070] The input / output interface of the production control device 200 is used to exchange information between the processor 201 and external devices. The communication interface of the production control device 200 is used to communicate with external terminals via a network connection. When executed by the processor 201, the computer program implements the steps of the production control method. The production control device 200 can ensure production operations and control the returned workpiece collection vehicle 100 to flexibly collect defective products. The production control device 200 can be used to control multiple returned workpiece collection vehicles 100.

[0071] refer to Figure 8 , an embodiment of the present disclosure provides a production control method. Figure 6An application environment of the production control method 1000 is shown.

[0072] Combine Figure 9 As shown, in an exemplary embodiment, the production control method 1000 includes steps S101 to S104.

[0073] Step S101: generating a receiving task signal. For example, the production control device 200 generates a receiving task signal in response to a defective product signal from a machine.

[0074] The MCS dispatch system can communicate with automated machines to achieve data sharing. For example, when there are multiple machines, the MCS dispatch system can determine which machine's NG station generated the LED basket containing returned workpieces. The MCS dispatch system can also send the receiving task to the AGV dispatch system.

[0075] Step S102: Determine the receiving location of the machine. Exemplarily, the production control device 200 determines the receiving location of the machine based on the defective product signal.

[0076] Based on the defective product signal, the AGV dispatching system can determine the receiving location of the machine in the factory map and select the appropriate return workpiece collection vehicle 100. The AGV dispatching system can use the factory-wide vehicle route topology map and SLAM map to confirm the receiving location and the first real-time location of the return workpiece collection vehicle 100.

[0077] Step S103: Obtain a first planned route from the first real-time position to the receiving position. For example, the production control device 200 obtains the first planned route from the first real-time position to the receiving position based on the first real-time position of the returned workpiece collection vehicle.

[0078] The AGV scheduling system obtains a first planned route based on the two determined locations and the topological map.

[0079] Step S104 : generating a first planned route signal and a receiving signal. Exemplarily, the production control device 200 generates a first planned route signal for controlling the returned workpiece collection vehicle 100 and generates a receiving signal for controlling the returned workpiece collection vehicle 100 .

[0080] The AGV scheduling system can generate a first planned route signal and a receiving signal. The production control device 200 can send the signal to the communication interface 11 of the returned workpiece collection vehicle 100 .

[0081] In response to the first planned route signal, the returned workpiece collecting vehicle 100 can drive the mobile carrier 1 to travel to the receiving position, and then drive the receiver 2 to receive the containing basket containing the returned workpieces.

[0082] The production control method 1000 of the embodiment of the present disclosure can implement acceptance of defective products from a machine, which is beneficial to the normal operation of production and reduces the proportion of defective products in the output of the production line.

[0083] In some embodiments, the production control method 1000 further includes generating an empty basket signal, which is used to control the basket feeder 4 of the returned workpiece collection vehicle 100. For example, the MCS scheduling system, based on the machine's basket turnover signal, assigns a basket delivery task to the AGV scheduling system. The AGV scheduling system generates the empty basket signal and sends it to the returned workpiece collection vehicle 100.

[0084] In other embodiments, it is also possible to not send an empty basket signal, but to automatically bind the receiving task to send a basket, so as to ensure that the machine has enough baskets.

[0085] In some embodiments, the production control method 1000 further includes step S105, obtaining a second planned route from the second real-time position of the returned workpiece collection vehicle 100 to the collection area position; and step S106, forming a second planned route signal. The second real-time position may be a receiving location. Exemplarily, the production control device 200 obtains a second planned route from the second real-time position of the returned workpiece collection vehicle 100 to the collection area position in response to a full collection signal from the returned workpiece collection vehicle 100; and forms a second planned route signal for controlling the returned workpiece collection vehicle 100. The AGV scheduling system obtains the second planned route, which is beneficial for ensuring the circulation of the returned workpiece collection vehicle 100 and is beneficial for the centralized collection of returned workpieces.

[0086] For example, the returned workpiece collection vehicle 100 is capable of collecting three full baskets.

[0087] In other embodiments, instead of a full signal, the receiving task can be automatically bound to delivering the returned workpieces to the collection area, and the second planned route can be formed when the first planned route is formed. For example, the production control device 200 can still form the second planned route based on the real-time situation of the production workshop 300 after the returned workpiece collection vehicle 100 has collected the returned workpieces.

[0088] In some embodiments, the production control method 1000 further includes step S07, obtaining a third planned route; and step S108, generating a third planned route signal. During the execution of the first planned route, the returned workpiece collection vehicle 100 may utilize, for example, the radar 6 to identify obstacles and may send an obstacle signal through the communication interface 11. The obstacle signal may be data provided by other feeding vehicles controlled by the AGV scheduling system, or data provided by another returned workpiece collection vehicle 100. For a returned workpiece collection vehicle 100, another stopped or moving returned workpiece collection vehicle 100 or other feeding vehicle is also an obstacle to itself.

[0089] In response to the obstacle signal, the production control device 200 determines a third planned route from the third real-time location of the returned workpiece collection vehicle 100 to the receiving location, generating a third planned route signal for controlling the returned workpiece collection vehicle 100. This arrangement effectively responds to emergencies and ensures that the returned workpiece collection vehicle 100 reaches the receiving location. For example, the first, second, and third planned routes of the returned workpiece collection vehicle 100 all avoid the real-time route location of the feeder vehicle used for normal production, ensuring normal production.

[0090] In an exemplary embodiment, the returned workpiece collection vehicle 100 may also encounter obstacles while executing the second planned route. The production control method 1000 further includes: in response to the obstacle signal, obtaining a fourth planned route from the fourth real-time position of the returned workpiece collection vehicle 100 to the collection area; and generating a fourth planned route signal for controlling the returned workpiece collection vehicle 100. This configuration effectively addresses emergencies and ensures that the returned workpiece collection vehicle 100 reaches the collection area.

[0091] For example, the AGV control system executed by the production control device 200 is used to obtain a planned route for the returned workpiece collection vehicle 100 from a starting position to a target position, and can generate a revised route from the real-time position to the target position during the execution of the planned route. The third planned route can be the revised route.

[0092] In an exemplary embodiment, the belt conveyor of the receiver 2 is capable of both forward and reverse rotation; the belt conveyor of the basket feeder 4 can also be configured to rotate both forward and reverse. At the collection area, the receiver 2 of the returned workpiece collection vehicle 100 can deliver returned workpieces, for example, by delivering a basket filled with returned workpieces along the Y-axis. Alternatively, an empty basket can be placed on the basket feeder 4, which can then collect the basket along the Y-axis.

[0093] For example, the AGV scheduling system will not schedule a full returned workpiece collection vehicle 100 to perform a receiving task.

[0094] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
