Description

Technical Field

[0001] The present invention relates to the technical field of information management, specifically to a production management system for solid wood furniture based on RFID. The present invention also relates to a production management method that utilizes such a production management system for solid wood furniture based on RFID. Background Art

[0002] Solid wood furniture refers to furniture made of solid wood logs or solid wood veneers. The production process of solid wood furniture includes the preparation of raw materials, the forming and finishing processing of solid wood components, the assembly of solid wood components, and quality inspection. Due to the wide variety and different shapes of solid wood furniture, mechanical processing and manual processing are often combined in actual production.

[0003] Traditional production management methods for solid wood furniture include the following: obtaining drawings containing the shape and specification information of solid wood furniture using software, then splitting the solid wood furniture into parts, printing multiple production task sheets. The production task sheets record the shape and specification of solid wood components in drawing format, as well as the processes and parameters in text form; the follow-up clerk dispatches production tasks to different workshops according to the production task sheets and follows up the production process; the follow-up clerk transfers the assembled solid wood components and drawings to the assembly workshop for assembly; finally, shipping is carried out according to the order information.

[0004] To improve the accuracy of furniture production and reduce the man-hours consumed by labor, the prior art provides a production management system for solid wood furniture based on RFID for panel furniture. For example, in a Chinese invention patent with the publication number CN110223152A and the title "A method and system for collecting production data of panel parts in a furniture manufacturing execution system", a production management system is provided, which includes a cutting platform, an edge banding platform, a drilling platform, a special-shaped processing platform, an intelligent sorting platform, a quality inspection platform, a packaging platform, a warehousing platform, a hub, and a database of the furniture manufacturing execution system connected in sequence, an RFID printer connected to the cutting platform, a PLC hardware interface connected to the cutting platform, the edge banding platform, and the drilling platform, an OPC / DNC hardware interface connected to the special-shaped processing platform and the intelligent sorting platform, a touch screen connected to the quality inspection platform and the packaging platform, a warehousing system interface connected to the warehousing platform, a call light system interface and a monitoring system interface connected to the hub, a fixed RFID reader / writer connected to the edge banding platform, the drilling platform, the special-shaped processing platform, and the intelligent sorting platform, a mobile RFID reader / writer connected to the quality inspection platform, the packaging platform, and the warehousing platform, and an EPR system interface connected to the database of the furniture manufacturing execution system. This system can match the existing equipment and production processes of the enterprise, take the execution of the production process as the core goal for information integration, use a variety of data collection technologies and collection lines for comprehensive collaborative work, obtain complete production information from multiple channels, realize the accurate and comprehensive collection and data display of data, not only improve the matching degree between different data, but also enhance the relevance of data in each process link.

[0005] However, different from panel furniture, on the one hand, the production process of solid wood furniture is more complex, including but not limited to shaping processing completed by different processing centers, shaping processing completed by manual labor, painting processing completed in a paint spraying room, partial assembly that can be completed by an assembly center, and partial assembly completed by manual labor. On the other hand, panel furniture mostly uses melamine-faced boards, and some even use semi-finished edge banded melamine-faced boards, which are no longer sanded or painted during the production process, so RFID tags can be pasted on the surface of the boards, and one RFID tag can be used throughout the process. However, the solid wood blanks of solid wood furniture need to go through milling, slicing, painting, etc., and there is no suitable position to paste RFID tags. Therefore, the above-mentioned prior art production management system and method are difficult to apply. Summary of the Invention

[0006] The purpose of the present invention is to provide a production management system and method for solid wood furniture based on RFID, which can at least solve one of the foregoing technical problems. The present invention specifically adopts the following technical solutions: An RFID-based production management system for solid wood furniture, comprising production terminals, terminal computers, servers, RFID tags, RFID label printers, and RFID readers. The production management system further includes a hanging rail distribution system located above and capable of connecting multiple production terminals. The RFID tag includes a nail shell, an RFID chip encapsulated in the nail shell, and a chuck threadedly connected to the head of the nail shell. A through-hole hanging hole is provided in the chuck, and the hanging hole is adapted to cooperate with the rail distribution system.

[0007] As a preferred embodiment, an external thread is provided on the outer wall of the head of the nail shell. The chuck includes a chuck body and a connecting column provided on the bottom surface of the chuck body. The connecting column is hollow, and an internal thread matching the external thread is provided on its inner wall.

[0008] As a preferred embodiment, an insertion column is provided on the bottom surface of the chuck body and located within the connecting column. A corresponding insertion hole is provided in the head of the nail shell for mating with the insertion column.

[0009] As a preferred embodiment, the chuck body is in the shape of a flat cube, and the hanging hole penetrates the thickness direction of the chuck body.

[0010] This application also provides an RFID-based production management method for solid wood furniture. Specifically, the production tasks corresponding to the solid wood blanks are written into the RFID tags, and the RFID label printer is used to insert the RFID tags into the solid wood blanks, and the insertion position is on the reference surface of the solid wood blanks. The hanging hole is used to hang the solid wood blanks, and the rail distribution system is used to transport the solid wood blanks to the corresponding work sections or sequentially transfer them between multiple work sections. At the corresponding work sections, the RFID reader reads the production tasks, and the production terminals process the solid wood blanks according to the production tasks to obtain solid wood components. Finally, before assembling the solid wood components, the RFID tags in the solid wood components are removed.

[0011] As a preferred embodiment, before the RFID tags are inserted into the solid wood blanks, the corresponding simulated assembly tasks of the solid wood blanks are written into the RFID tags.

[0012] As a preferred embodiment, when the solid wood blank is a strip-shaped workpiece, the reference surface is the end face of the solid wood blank, and the insertion position of the RFID tag is at the center of the reference surface of the solid wood blank.

[0013] As a preferred embodiment, when the solid wood square stock is a plate-shaped workpiece, the reference plane is the bottom surface of the solid wood square stock, and the driving position of the RFID tag is located at a position close to the side surface on the reference plane of the solid wood square stock.

[0014] As a preferred embodiment, the production tasks written into the RFID tag include the specification and shape of the corresponding solid wood square stock, the machining center code, the process and parameters.

[0015] As a preferred embodiment, the simulated assembly tasks written into the RFID tag include the types and quantities of solid wood components and fittings, and the assembly method.

[0016] Compared with the prior art, a solid wood furniture production management system and method based on RFID provided by the present invention overcomes the technical problems that the prior art production management system and method based on RFID cannot adapt to and meet the production characteristics of solid wood furniture. Specifically, by installing the RFID chip into the nail gun housing and then nailing it into the wood, it can avoid the influence of the existence of the RFID chip on the processing process of solid wood furniture, and the same RFID tag can be used throughout the process. Particularly, the driving position of the RFID tag is selected on the processing reference plane of the solid wood square stock, so that a chuck can be installed at the head of the nail gun housing without affecting the processing process, and further, through the setting of the chuck, the hoisting and transportation of the solid wood square stock are realized, making the transfer of the solid wood square stock more efficient and flexible, and meeting the requirements of the transfer between the machining center and the manual processing workshop in the production process of solid wood furniture.

[0031] Next, taking the stool board of the solid wood furniture 9 - a backrest chair as shown in Figure 3 as an example, the RFID-based solid wood furniture production management method of this application will be described. As shown in combination with Figure 4 , Figure 3 the solid wood furniture 9 can be disassembled into a pair of crossbars 91, a pair of vertical bars 92, and a board surface 93. The solid wood square materials 2 used for the crossbars 91 and vertical bars 92 are strip-shaped workpieces. Referring to Figure 5 , their reference surface 21 is the end face of the solid wood square material 2, and the punching position of the RFID tag 1 is at the center of the reference surface 21. The solid wood square material 2 used for the board surface 93 is a plate-shaped workpiece. Referring to Figure 6 , its reference surface 21 is the bottom surface of the solid wood square material 2, and the punching position of the RFID tag 1 is at a position on the reference surface 21 close to any one side of the solid wood square material 2.

[0032] The processing of the crossbar 91 includes the following steps: First, use the RFID reader / writer 4-0 to write the production task and assembly task of the crossbar 91 into the RFID tag 1, including but not limited to (1) the profiling section and its specification shape, machining center code, process, and parameters, (2) the repair section and its specification shape, machining center code, process, and parameters, (3) the painting section and its specification shape, machining center code, process, and parameters in sequence; Subsequently, use the RFID labeling machine 6 to insert the RFID tag 1 into the center of the reference surface 21 of the solid wood square stock 2, and assemble the chuck 12. Use the chuck 12 to hang the solid wood square stock 2 on the hanging rail distribution system 7. The hanging rail distribution system 7 sends the solid wood square stock 2 to the profiling section. The RFID reader 5-1 reads the production tasks therein to enable the production terminal 3-1 to perform profiling processing, including but not limited to forming and punching holes. The terminal computer 4-1 can display the production tasks and processing progress for manual intervention; After that, the hanging rail distribution system 7 sends the solid wood square stock 2 to the repair section. The RFID reader 5-4 reads the production tasks therein and displays them through the terminal computer 4-4. Manually operate the small equipment or tool B to perform repairs; After that, the hanging rail distribution system 7 sends the solid wood square stock 2 to the painting section. The RFID reader 5-6 reads the production tasks therein and displays them through the terminal computer 4-6. Manually operate the small equipment or tool C to perform painting; Finally, the hanging rail distribution system 7 sends the solid wood component (i.e., the cross bar 91) to the assembly section.

[0033] The difference in the processing process of the vertical bar 92 from that of the cross bar 91 lies in that the profiling processing implemented in the profiling section includes but is not limited to forming and mortising.

[0034] The processing of the panel surface 93 includes the following steps: First, use the RFID reader 4-0 to write the production tasks and assembly tasks of the cross bar 91 into the RFID tag 1, including but not limited to (1) the panel processing section and specifications, processing center code, process and parameters, (2) the repair section and specifications, processing center code, process and parameters, (3) the painting section and specifications, processing center code, process and parameters in sequence; Subsequently, use the RFID labeling machine 6 to insert the RFID tag 1 into the side of the reference surface 21 of the solid wood square stock 2, and assemble the chuck 12. Use the chuck 12 to hang the solid wood square stock 2 on the hanging rail distribution system 7. The hanging rail distribution system 7 sends the solid wood square stock 2 to the panel processing section. The RFID reader 5-2 reads the production tasks therein to enable the production terminal 3-2 to perform panel processing, including but not limited to thicknessing and mortising. The terminal computer 4-2 can display the production tasks and processing progress for manual intervention; After that, the hanging rail distribution system 7 sends the solid wood square stock 2 to the repair section. The RFID reader 5-4 reads the production tasks therein and displays them through the terminal computer 4-4. Manually operate the small equipment or tool B to perform repairs; Subsequently, the hanging rail distribution system 7 sends the solid wood square materials 2 to the paint spraying section. The RFID reader / writer 5-5 reads the production tasks therein to enable the production terminal 3-5 to perform paint spraying. The terminal computer 4-5 can display the production tasks and processing progress for manual intervention; Finally, the hanging rail distribution system 7 sends the solid wood components (i.e., the board surface 93) to the assembly section.

[0035] After the RFID reader / writer 5-7 in the assembly section reads the simulated assembly tasks therein and confirms the quantity, type, and assembly method of the solid wood components, it is displayed through the terminal computer 4-7, and the manual assembles according to the simulated assembly tasks. Optionally, before assembly, the manual removes the RFID tag and repairs the nail holes formed by the RFID tag.
