Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a method, apparatus, electronic device, and storage medium for unpacking. Background Technology

[0002] In the field of sheet metal processing and warehousing logistics, automated production lines typically rely on MES (Manufacturing Execution System) to schedule the supply and use of sheet metal. In traditional processes, when a production line issues a sheet metal demand, the warehouse needs to manually check the inventory status (e.g., unpacked and unpacked quantities) and complete the unpacking, handling, and feeding operations manually or with semi-automated equipment. Existing technologies have the following limitations:

[0003] Manual unpacking and handling are slow and prone to errors, especially when faced with high-frequency and multi-specification board demand, making it difficult to meet real-time production pace. Traditional unpacking methods (such as manual cutting) can easily damage the surface of the boards and lack standardized processes, affecting the quality of subsequent processing. Moreover, they can easily cause injury to the human body during handling.

[0004] Meanwhile, the linkage between the MES system and the warehousing system is weak. The location tracking of unopened boards and the dynamic update of inventory rely on manual records, which can easily lead to errors in the statistical analysis of the number of unopened boards, resulting in material supply interruptions or redundancy.

[0005] Therefore, there is an urgent need for an automated unpacking and packaging method that works in deep collaboration with MES. By integrating the coordinated control of WMS, WCS, stacker cranes, RGV, cutting mechanisms and robotic arms, it is possible to achieve precise response to board material demand, efficient packaging removal and seamless material supply, thereby improving the level of intelligence in warehousing and logistics. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the purpose of the present invention is to provide a packaging unpacking method, apparatus, electronic device and storage medium, which completes the unpacking operation in an automated manner and improves the packaging unpacking efficiency.

[0007] The objective of this invention is achieved through the following technical solution:

[0009] Receive board material demand information sent by the MES system, and determine the target board material and its corresponding target quantity based on the board material demand information;

[0010] Determine the number of unpacked target boards in the warehouse. If the number of unpacked boards is less than the target quantity, obtain the number of unpacked target boards in the warehouse. If the sum of the number of unpacked boards and the number of unpacked boards is greater than or equal to the target quantity, then perform the following unpacking operation:

[0011] Obtain the target location of the unopened target board in the warehouse, and use a stacker crane to send the unopened target board to the RGV, which then transports the unopened target board to the buffer location;

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the embodiments of the present invention, they are protected by patent law.

Obviously, the described embodiments are only some embodiments of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of the present invention.

Any embodiment or design described as "exemplary" or "for example" in embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] This invention achieves efficient collaboration between the WMS system, WCS system, MES system, stacker crane, RGV, cutting mechanism, and robotic arm during the unpacking and packaging process, reducing manual intervention, improving the automation level and efficiency of the production line, and meeting the high-efficiency production requirements of intelligent manufacturing. The following is a detailed description in conjunction with the accompanying drawings.

[0052] Example 1

[0053] Please refer to Figure 1 and 2 The diagram illustrates a method for unpacking according to the present invention, which may include the following steps:

[0054] S110. Receive the board material demand information sent by the MES system, and determine the target board material and its corresponding target quantity based on the board material demand information.

[0055] The WMS system receives the board material demand information sent by the MES system and automatically determines the different models of boards and the required quantity of each type of board based on the board material demand information. Here, the different models of boards determined are recorded as target boards, and the required quantity of target boards is recorded as target quantity.

[0056] The demand information for sheet materials can be based on production orders. These production orders can be automatically generated by the MES system according to customer needs. The production orders include not only the demand for various sheet materials, but also the demand for related accessories. Here, the required quantity of various sheet materials is automatically transported based on the production orders so that the MES system can perform subsequent processing operations.

[0057] After the WMS system obtains the target board and its corresponding target quantity, it uses the WCS system to retrieve the existing boards from the warehouse (here, a vertical warehouse is used to store various boards, accessories, and finished products, etc.) according to different models and demand quantities, and put them into the same stack for caching, thus completing the board matching operation.

[0058] Before matching boards, the WMS system needs to determine if the remaining quantity of unpacked boards in the warehouse (referring to the automated warehouse) is insufficient. If so, it will automatically generate an unpacking task, which means sending the unpacked boards of the corresponding model to the unpacking station for unpacking. After unpacking, the boards will be automatically returned to the warehouse and the inventory status will be updated before proceeding with the subsequent matching operation.

[0059] S120. Determine the number of unpacked target boards in the warehouse. If the number of unpacked boards is less than the target quantity, obtain the number of unpacked target boards in the warehouse. If the sum of the number of unpacked boards and the number of unpacked boards is greater than or equal to the target quantity, then perform the unpacking operation in steps S130-S150.

[0060] The model, quantity, and whether the packaging of the boards in each storage location have been unpacked are updated in real time based on operations such as board entry, unpacked boards, and return of remaining boards after matching.

[0061] Therefore, after determining the target quantity of the target board, the unpacked and unpacked quantities of the target board in the warehouse can be obtained. When the sum of the unpacked and unpacked quantities is greater than or equal to the target quantity, the subsequent unpacking operation can begin.

[0062] The quantities of unpacked and unpacked items refer to the number of target boards that have been unpacked and the number of target boards that have not been unpacked. As for how many packages need to be unpacked in the subsequent unpacking operation, it depends on the target quantity. For example, if the number of target boards that have been unpacked is 15 and the target quantity is 30, and assuming that each unpacked target board contains 10 boards, then 2 packages need to be unpacked.

[0063] S130. Obtain the target location of the unopened target board in the warehouse, and use a stacker crane to send the unopened target board to the RGV, which then transports the unopened target board to the buffer location.

[0064] The RGV status is checked. If its status is 1, it indicates that it is in an empty state. The stacker crane is then called to send the unpacked board material in the warehouse to the RGV. At this time, the RGV status is updated to 2, that is, the loading state. Then the status of the buffer position (D7 bit) is checked. When the status of the buffer position is 2, that is, the buffer position is in an idle state, the RGV control word is controlled to be 1, so that the RGV transports the unpacked target board material to the buffer position (the buffer position, unpacking position board, and material storage and retrieval position are collectively referred to as the unpacking position). The status of the buffer position is updated to 1, that is, the non-idle state.

[0065] S140. Switch to unpacking mode, transport the unopened target board in the cache position to the unpacking position, and use a cutting mechanism to cut open the packaging of the unopened target board during the transportation process.

[0066] To save resources, including equipment and space, the unpacking area and the board preparation area in this embodiment of the invention share the same equipment (referred to as the equipment in area D; the machine in area D can be used for unpacking and board preparation, 1 is the unpacking mode, and 2 is the board preparation mode). Therefore, it is necessary to confirm the working mode of the equipment in area D. If the working mode of the equipment in area D is not the unpacking mode, the system will automatically send a mode switching command to the machine to switch its working mode to the unpacking mode.

[0067] When the switch is successful, the status of the unpacking position is detected. If the unpacking position is in an empty state, the unopened target board is sent to the unpacking position, the status of the buffer position is updated to an idle state, the status of the unpacking position is updated to a loaded state, and then a command is sent to transport the unopened target board from the buffer position to the unpacking position (position D6) via conveyor belt. When the board is sent from position D7 to position D6, the machine will extend a small gear, drive the gear to rotate and extend above the path between the buffer position and the unpacking position, so as to cut the packaging of the unopened target board as it passes by.

[0068] S150. Use a robotic arm to grab the unopened target boards one by one and move them to the board storage position until all the unopened target boards have been grabbed to the board storage position.

[0069] When the board reaches position D6, the system (PLC) automatically detects the status of position D6 and the board storage / retrieval position (position D2). When position D6 is loaded and position D2 is empty, the system automatically switches to the unpacking state, at which point unpacking and board grabbing can begin. This process includes: raising positions D6 and D2; using a robotic arm to grab the unopened target boards from position D6 (or manually removing the packaging if it is not fully opened) one by one to position D2, until the number of target boards in position D2 reaches the number of unopened target boards; lowering positions D6 and D2, updating the status of position D6 to empty; and calling the stacker crane to re-enter the board from position D2 into the warehouse (transporting it to the corresponding storage location in the automated warehouse based on the historical usage frequency of the target board).

[0070] Update the quantity of unpacked target boards in the warehouse. When the quantity of unpacked target boards is greater than or equal to the target quantity, perform a board matching operation.

[0071] In other embodiments, a preset threshold can be used to determine whether to perform a packaging unpacking operation. For example, if the number of unpacked target boards is less than the preset threshold, a packaging unpacking operation can be performed until the number of unpacked target boards is greater than or equal to the preset threshold.

[0072] Example 2

[0073] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a packaging unpacking device disclosed in an embodiment of the present invention. Figure 3 As shown, the unpacking device may include:

[0074] The receiving unit 210 is used to receive the board material demand information sent by the MES system, and determine the target board material and its corresponding target quantity based on the board material demand information.

[0075] The judgment unit 220 is used to determine the number of unpacked target boards in the warehouse. When the number of unpacked boards is less than the target quantity, it obtains the number of unpacked target boards in the warehouse. When the sum of the number of unpacked boards and the number of unpacked boards is greater than or equal to the target quantity, the following unpacking operation is performed:

[0076] The first conveying unit 230 is used to obtain the target location of the unopened target board in the warehouse, and use a stacker crane to send the unopened target board to the RGV, and the RGV transports the unopened target board to the buffer location;

[0077] The second conveying unit 240 is used to switch to the unpacking mode to transport the unopened target board at the buffer position to the unpacking position. During the transport process, a cutting mechanism is used to cut open the packaging of the unopened target board.

[0078] The gripping unit 250 is used to use a robotic arm to grip each of the unopened target boards and move them to the board storage position until all the unopened target boards have been gripped to the board storage position.
