Description

Technical Field

[0001] The present invention relates to the technical field of material management, and in particular to a material management distribution method based on three-dimensional software. Background Art

[0002] Traditional material management is that workshop workers place the parts of product components on commonly used logistics transfer pallets according to the design BOM details, and then transfer them to the assembly process by logistics equipment for assembly. Since workers place the parts according to the design details and there is no fixed placement standard, there is a certain degree of inconsistency in the types and quantities of parts placed on each pallet, which in turn causes problems such as insufficient supply of parts in the subsequent assembly processes of each production line. In addition, if some parts are not placed according to the relative position during assembly, in order to facilitate assembly after logistics transfer to the assembly process, the parts in the pallet need to be turned over and adjusted before further assembly can be carried out. For some relatively heavy parts, it is even more time-consuming and labor-intensive, affecting production progress.

[0003] On October 18, 2022, the Chinese invention patent disclosed the "Material Packing and Placement Calculation Method, Device and Storage Medium" (application number: 202210685872.0). This invention provides a method for calculating the material packing and placement method. By setting the full box rate and setting the packaging sequence based on product characteristics, combined with existing business scenarios, materials are placed in a layered manner, the remaining space is continuously optimized, the packing placement order and position are obtained, and finally the packaging plan is output.

[0004] This solution has the following three disadvantages: 1. This solution calls the algorithm module to output the box type selection, packing order and placement method according to a series of conditions such as the weight to be packed, the size to be packed and the material attributes of each material to be calculated. However, for non-standard shaped materials such as zigzag and arc-shaped special-shaped bent metal sheets and materials with sizes exceeding the size of the transport tool (pallet), the algorithm cannot be used to effectively calculate the placement position and quantity.

[0005] 2. It is impossible to effectively identify the three-dimensional model features of special-shaped materials through algorithms or conditions to ensure that the materials to be matched are placed stably and safely on the transfer tool (pallet).

[0006] 3. This solution is aimed at box-type transport vehicles. The volume is calculated by setting the full box rate standard to achieve material distribution and placement. However, if the transport vehicle is non-box type, open type or the material size exceeds the transport vehicle, the placement position and quantity cannot be effectively calculated through the algorithm.

[0007] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0008] The purpose of the present invention is to provide a material management and distribution method based on three-dimensional software in view of the deficiencies of the prior art.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is: A first aspect provides a material management and allocation method based on three-dimensional software, comprising the following steps: Establish model library and pallet 3D model in 3D software; Create a matching group, select the 3D model of the material to be matched and add it to the matching group, and extract the material details of each material to be matched to form the matching details; Call the WebService function to pass the distribution details to Windchill; Based on the pallet details, the 3D model of the material to be palletized is placed on the pallet model according to the preset model creation rules to create a pallet model, and a pallet drawing is created for the pallet model according to the preset drawing creation rules; Check the created panel model and panel drawing into the Windchill product library; After the panel details, panel model, and panel drawings are associated with the process route and process steps of the Windchill platform, they are sent to the MES system so that the production site can view the 3D assembly model and panel drawings of the panel.

[0010] A second aspect provides a material management and distribution system, including 3D CAD software, WebService, Windchill and MES; The three-dimensional CAD software has a built-in model library, a matching detail creation module, a matching model drawing creation module, a matching detail transfer module, and a matching model drawing transfer module; The pan matching detail creation module is used to create a pan matching group, select the three-dimensional model of the material to be matched from the model library and add it to the pan matching group, and extract the material details of each material to be matched to form the pan matching details; The distribution detail transfer module is used to call the WebService function to transfer the distribution details in the distribution details to Windchill; The pallet model drawing creation module is used to place the three-dimensional model of the material to be palletized on the pallet model according to the preset model creation rules based on the pallet details, create a pallet model, and create a pallet drawing for the pallet model according to the preset drawing creation rules; The panel model drawing transfer module is used to transfer the created panel model and panel drawing to Windchill; Said Windchill includes Oracle database, process platform and product repository; The Oracle database is used to store the distribution details; The product repository is used to store the created matching models and matching drawings; The process platform is used to provide process routes and processes, and the process routes and processes are associated with the plate-matching details, plate-matching models, and plate-matching drawings; The MES system is used to receive the panel details, panel model, and panel drawings, so that the production site can view the three-dimensional assembly model and panel drawings of the panel.

[0011] The present invention has outstanding substantive features and significant progress compared to the prior art. Specifically, (1) In the material management and allocation operation mode, by quickly calling the corresponding pallet 3D model and the 3D model of the material to be matched, the 3D model of the material to be matched is quickly placed on the corresponding pallet 3D model to generate the matching pallet model and matching pallet drawing. Therefore, there are no requirements for the shape and size of the material or the type of pallet. The model of the material to be matched can be placed on the pallet model through the method of rapid assembly, effectively ensuring the rationality of the direction, position, quantity, height and other information of the 3D model of the material placed on the pallet model.

[0012] (2) Graphical material management and allocation methods. The palette model allows operators to intuitively arrange materials on site according to the three-dimensional visualization view. The palette drawing can be used to quickly view the attribute information of the materials to be paletted and the technical requirements that need to be paid attention to.

[0013] (3) Avoid rework in subsequent operation processes. Place the materials to be assembled on the pallet model according to the relative positions during subsequent assembly. After the subsequent logistics are transferred to the assembly process, there is no need to turn over or adjust the positions of the components in the pallet according to the assembly positions, which effectively improves the overall production progress.

[0014] (4) Material management and allocation achieves a balance in the production line rhythm. By allocating product materials according to the number of production lines at the R&D end, the status of material allocation on site can be effectively guided to ensure that the supply of components and raw materials for each production line can meet production needs.

[0015] (5) Material management allocation and delivery method: Integrate the Windchill system to realize the automatic association of the batch model and batch details (material 3D model grouping details) batch drawings with the process route and process of the Windchill process platform, and then transfer them to MES and send them to the production site.

[0016] (6) Material management distribution display form: the production site can view the three-dimensional assembly model (pallet + material) and the pallet drawing of the pallet through mobile terminals-PDA, fixed terminals-host computers, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a flow chart of the material management and distribution method of the present invention.

[0018] Figure 2 It is a principle block diagram of the material management and distribution system described in the present invention. DETAILED DESCRIPTION

[0019] With the continuous development of intelligent factories, during the production process, each production line independently distributes parts and raw materials (materials are placed on pallets) to ensure that the supply of parts and raw materials for each production line can meet production needs, avoiding insufficient supply or excessive distribution of parts for some production lines due to the needs of other production lines or the placement of different types of parts on the same pallet. This greatly affects production efficiency and production quality, and indirectly increases production costs. Therefore, higher and higher requirements are placed on the accuracy of the placement details and positions of workpieces in the transfer pallet and the stability of logistics transfer.

[0020] Currently, neither the production plan BOM details nor the production plan list issued by the MES system can effectively control the details and placement of corresponding components on different types of pallets. Therefore, to ensure that the supply of components and raw materials for each production line can meet production needs, it is necessary to have higher requirements for the details, specific locations and placement requirements of product parts on pallets.

[0021] To solve the above problems, the present invention proposes a method for integrating Windchill+MES based on 3D software Creo. Through secondary development of the 3D software Creo, the 3D models of materials to be matched are quickly grouped and matching details are created in the product design link; the matching model (pallet model + model parts placed on the pallet), matching details, and matching drawings are created based on the Creo software; through software integration, the matching details (material 3D model grouping details), visualized 3D matching models, and matching drawings on the Creo side are transferred to Windchill and issued to the production MES system, guiding workers to accurately and quickly place product materials on corresponding pallets according to the visualized 3D matching models, matching details, and matching drawings in the on-site mobile terminals and fixed terminals.

[0022] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0023] Example 1 This embodiment provides a material management and allocation method based on three-dimensional software, such as Figure 1 As shown, the following steps are included: Create multiple material 3D models and pallet 3D models in the 3D software.

[0024] It can be understood that each material three-dimensional model is provided with a corresponding material detail, and the material detail includes at least drawing number, name, material, quantity, and weight.

[0025] Select the 3D model of the material to be matched to create a matching group, and extract the material details of each material to be matched to form a matching detail. The matching details at least include the matching group number, matching model number, drawing number, name, material, quantity, weight and total weight. Among them, the matching model number is the number of the material 3D model in the matching details.

[0026] It can be understood that each material to be matched is a part in the matching set, and multiple parts constitute a matching model.

[0027] Specifically, in the model selection interface, select the 3D model of the material that needs to be matched or click the corresponding 3D model under the model tree, and the selected 3D models can be automatically merged into a group under the model tree, and the created group is automatically named as a group containing the matching number according to the rules, that is, the matching group.

[0028] For example, when a group is created for the first time, the group name is "No. 1 matching disk". When the "group" is created again subsequently, Xi'an will judge the existing group name and automatically add 1 to the group name, thus forming "No. 2 matching disk", "No. 3 matching disk"... "No. N matching disk".

[0029] After the distribution details are formed, the WebService function is called to pass the distribution details to Windchill.

[0030] Windchill is a set of integrated application software launched by PTC to manage the entire life cycle of products and processes.

[0031] It is understandable that after creating the panning details, the panning group and panning details are reviewed. If the review result is complete, the WebService function is called to pass the panning details to Windchill; if the review result is incomplete, the panning group and panning details are improved. Among them, the review result of completeness means that all material details are complete.

[0032] Furthermore, each time the WebService function is called to pass the disk configuration information in the disk configuration details to Windchill, the existing data is deleted and replaced with the newly passed disk configuration information.

[0033] While calling the WebService function to pass the pallet details to Windchill, the 3D model of the material to be palletized is placed on the pallet model according to the preset model creation rules based on the pallet details to create a pallet model, and a pallet drawing is created for the pallet model according to the preset drawing creation rules.

[0034] The specific steps are as follows: 1) Based on the pallet details, place the 3D model of the material to be palletized on the pallet model according to the preset model creation rules to create a pallet model.

[0035] Specifically, the three-dimensional model of the material to be matched in the matching details is assembled with the three-dimensional model of the pallet to form a matching model.

[0036] The preset model creation rules at least include: The largest surface of the three-dimensional model of the material to be matched coincides with the top surface of the pallet model, the heaviest piece in the material to be matched coincides with the column of the pallet model, and the distance between any two three-dimensional models of the material to be matched placed one above the other is the preset distance.

[0037] Preferably, the preset spacing is 10 mm.

[0038] The setting of the preset model creation rules facilitates the automatic and rapid preliminary creation of the pallet model.

[0039] It can be understood that after the configuration model is created, the configuration model is reviewed. If the review result is complete, the configuration model is checked into the Windchill product library; if the review result is incomplete, the configuration model is fine-tuned based on the preset adjustment strategy.

[0040] In one embodiment, the preset adjustment strategy license includes assembly sequence, corresponding position after assembly, pallet load-bearing capacity, and pallet load-bearing height.

[0041] Specifically, the adjustment is made by using the instructions in the two-opening rapid assembly tool, such as surface contact, rotation, reverse, movement, fixed constraints and other adjustment instructions, and the final disk model is completed through fine-tuning.

[0042] 2) Create a panel drawing for the panel model according to the preset drawing creation rules.

[0043] Automatically create a layout drawing based on the adjusted layout model. The drawing format is created based on the drawing creation rules in the provided background drawing creation rule library. Specifically, the preset drawing creation rules at least include the frame ratio and projection direction. For example: the frame ratio is 1:12, the projection direction: select the TOP surface for the left view, and the RIGHT surface for the right view, etc.

[0044] Similarly, after creating the panel drawing, use 3D software to open the panel drawing to review it. If the review result is complete, check the panel drawing into the Windchill product library; if the review result is incomplete, fine-tune the panel drawing.

[0045] After the panel distribution model and panel distribution drawing are created, the created panel distribution model and panel distribution drawing will be checked into the Windchill product library.

[0046] After the distribution details, distribution models, and distribution drawings are stored in Windchill, they are associated with the process routes and procedures of the Windchill platform.

[0047] Finally, the panel details, panel model and panel drawings are sent to the MES system so that the production site can view the 3D assembly model and panel drawings of the panel.

[0048] In the material management and allocation operation mode of this embodiment, by quickly calling the corresponding pallet three-dimensional model and the three-dimensional model of the material to be matched, the three-dimensional model of the material to be matched is quickly placed on the corresponding pallet three-dimensional model to generate a matching pallet model and matching pallet drawings. Therefore, there is no requirement for the shape and size of the material and the type of pallet. The model of the material to be matched can be placed on the pallet model by a quick assembly method, effectively ensuring the rationality of the direction, position, quantity, height and other information of the three-dimensional model of the material placed on the pallet model. The matching pallet model is convenient for operators to intuitively place the materials on site according to the three-dimensional visualization view, and the matching pallet drawings can be used to quickly view the attribute information of the materials to be matched and the technical requirements and other standards that need to be paid attention to. The materials to be matched are placed and assembled on the pallet model according to the relative position during the subsequent assembly. After the subsequent logistics is transferred to the assembly process, there is no need to turn over and adjust the position of the components in the pallet according to the assembly position again, which effectively improves the overall production progress. By allocating the product materials to the pallet according to the number of production lines at the R&D end, the state of the material matching on site can be effectively guided to ensure that the supply of components and raw materials for each production line can meet the production needs. The Windchill system is integrated to realize the automatic association of the tray model, tray details (material 3D model grouping details) and tray drawings with the process route and process of the Windchill process platform, and then the MES is transmitted and sent to the production site. The production site can view the 3D assembly model (pallet + material) and tray drawings of the tray through mobile terminals-PDA, fixed terminals-host computers, etc.

[0051] The pan detail creation module is used to create a pan group, select the three-dimensional model of the material to be panned from the model library and add it to the pan group, and extract the material details of each material to be panned to form the pan detail. The material details of the material to be panned include at least the drawing number, name, material, quantity, and weight; the pan detail includes at least the pan group number, pan model number, drawing number, name, material, quantity, weight, and total weight.

[0052] The said plate distribution detail transmission module is used to call the WebService function to transmit the plate distribution details in the plate distribution details to Windchill. It should be noted that each time the WebService function is called to transmit the plate distribution information in the plate distribution details to Windchill, the existing data is deleted and replaced with the newly transmitted plate distribution information.

[0053] The pallet model drawing creation module is used to place the three-dimensional model of the material to be palletized on the pallet model according to the preset model creation rules based on the pallet details, create a pallet model, and create a pallet drawing for the pallet model according to the preset drawing creation rules.

[0054] The preset model creation rules at least include: The largest surface of the three-dimensional model of the material to be matched coincides with the top surface of the pallet model, the heaviest piece in the material to be matched coincides with the column of the pallet model, and the distance between any two three-dimensional models of the material to be matched placed one above the other is the preset distance.

[0055] The panel model drawing transfer module is used to transfer the created panel model and panel drawing to Windchill.

[0056] Said Windchill includes Oracle database, process platform and product repository; The Oracle database is used to store the distribution details; The product repository is used to store the created matching models and matching drawings; The process platform is used to provide process routes and processes, and the process routes and processes are associated with the plate-matching details, plate-matching models, and plate-matching drawings; The MES system is used to receive the panel details, panel model, and panel drawings, so that the production site can view the three-dimensional assembly model and panel drawings of the panel.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
