[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] This invention relates to the field of aluminum alloy door and window and curtain wall processing technology, specifically to the realization of intelligent assembly lines with MES and ERP software in door and window assembly.

[0034] like Figure 1 As shown, according to the assembly process of doors and windows and the corresponding standard working hours ratio, the intelligent assembly line for doors and windows includes: frame assembly line 6, pressure line assembly line 7 and main assembly line, wherein the main assembly line includes adjacent first assembly area 1 and second assembly area 2.

[0035] Multiple parallel assembly line branches 6 are arranged on one side of the first assembly area 1. The first assembly area 1 is equipped with a single-layer transmission station, such as... Figure 2 As shown, the single-layer transmission platform includes a conveyor roller 11 and a lifting rod 12. The conveyor roller 11 is used to transport doors and windows, and the doors and windows are assembled on the raised lifting rod 12. Multiple parallel pressing lines 7 are arranged on one side of the second assembly area 2. The second assembly area 2 is equipped with a double-layer transmission platform 21, as shown... Figure 3As shown, the double-layer conveyor 21 includes a lower rubber roller 211 and an upper rubber roller 212. The lower rubber roller 211 is at the same height as the conveyor roller 11 of the first assembly area 1 and is horizontally aligned. The upper rubber roller 212 is aligned with the pressure line 7.

[0036] The frame assembly line 6 includes processes such as material preparation, application of end sealing adhesive, insertion of corner brackets (including corner pieces), and frame assembly (including mullions). Multiple parallel frame assembly lines 6 are set up in the intelligent door and window assembly line.

[0037] The pressure line branch line 7 is equipped with pressure line measurement, pressure line cutting, and pressure line installation processes. Multiple parallel pressure line branch lines 7 are set up in the intelligent door and window assembly line.

[0038] The assembly line includes processes such as inserting adhesive strips, applying waterproof glue, installing flip frames, injecting corner glue, installing and debugging frames and sashes, quality inspection, packaging, label printing, and timely data reporting during operation.

[0039] The first assembly area 1 is equipped with multiple single-layer transfer stations, corresponding to the frame assembly line 6, allowing for multi-station transfer of assembled window frames to the main line. Threading adhesive strips, applying waterproof adhesive, installing flip frames, and injecting corner sealant are all completed on the single-layer transfer stations. When the lifting rod 12 of the single-layer transfer station is raised, assembly and installation can be carried out on top, while the lower conveyor roller 11 can transport the rear window frames, ensuring that adjacent processes are not interfered with by other processes.

[0040] The second assembly area 2 is equipped with multiple double-layer transfer stations 21, corresponding to the crimping lines 7. The MES management system optimizes the allocation based on the working status of each crimping line 7. The window frames that need to be crimped are transferred to the corresponding crimping line 7 picking position via the lower rubber roller 211, without interference between processes. At the same time, the crimped window frames are returned to the main line via the upper rubber roller of the double-layer transfer station 21 and passed to the next process, without interference between them.

[0041] In the assembly of doors and windows, the sub-line assembly and the main line assembly are combined. At the same time, the main line realizes the separation of transmission between the upper and lower parts to ensure processing in the same process. This realizes that various door and window types are mixed and assembled without mutual interference. It avoids the impact of processing time delays and errors in a single process on the operation of the entire assembly line. In case of emergencies and accidents, the process can be adjusted in time, ensuring that the relevant functions of the MES control system are effectively implemented and the smart factory is better implemented.

[0042] The following is a detailed explanation of each part:

[0043] The frame divider consists of 6 parts:

[0044] Given the numerous procedures and interference factors involved in the early stages and assembly of the frame, multiple independent operating workbenches are set up, allowing multiple parallel and identical processes to be carried out simultaneously without interference between them.

[0045] Each operator scans the code at the industrial control station to retrieve ERP data from the server, selects the appropriate materials from the corresponding positions on the complete set of material carts according to the processing requirements of the orders allocated by the MES management system, and operates independently without interfering with each other.

[0046] Each process is assembled according to the ERP technical data requirements (displayed on the electronic dashboard) through the industrial control dashboard, achieving paperless office operations.

[0047] After each window frame is assembled, the QR code on the profile is scanned with a barcode scanner to prepare for subsequent processes. At the same time, MES process feedback is sent to schedule subsequent production and process the work accordingly.

[0048] The pressure line is divided into 7 parts:

[0049] Given the lengthy time required for measuring, cutting, and installing the wire, and the numerous interfering factors, a dedicated adjustable-height installation lifting platform (such as...) is installed. Figure 4 As shown in the figure, multiple parallel identical processes are carried out simultaneously without interfering with each other, including the wireless Bluetooth wire cutting saw.

[0050] Each process, according to the order processing requirements assigned by the MES control system, moves the window frames that need to be installed with pressure lines from the lower discharge section of the double-layer conveyor 21, without interfering with each other.

[0051] Using a Bluetooth wireless measuring device, the measuring ruler measures the length of the pressure line to be installed and wirelessly transmits the data to the pressure line cutting saw for cutting, reducing human error and ensuring cutting accuracy. While the pressure line is being measured, the pressure line cutting saw cuts according to the instructions, saving pressure line waiting time and improving production efficiency.

[0052] like Figure 4 As shown, the lifting worktable includes a base 71, a guide shaft 73, and a lifting frame 72. The lifting frame 72 is vertically slidably connected to the base 71 via the guide shaft 73. When the lifting frame 72 is lowered, it is flush with the lower rubber roller 211 of the double-layer transmission table 21 in the second assembly area 2. When the lifting frame 72 is raised, it is flush with the upper rubber roller 212 of the double-layer transmission table 21 in the second assembly area 2. To accommodate the different height requirements during installation of the pressure line when the lower layer of the double-layer transmission table 21 extends out of the window frame and the upper layer returns, an adjustable-height lifting worktable is provided, reducing the handling intensity for operators.

[0053] Assembly Main Line:

[0054] like Figure 1As shown, the main assembly line includes, from left to right, a first assembly area 1, a second assembly area 2, a transfer area 3, a debugging and inspection area 4, and a packaging area 5. The first assembly area 1 is equipped with a single-layer transfer table, the second assembly area 2 is equipped with a double-layer transfer table 21 and a window-forming transition frame 22, the transfer area 3 is equipped with an intelligent 90° shuttle car 31 and a frame-type vertical intelligent automated storage system 32, the debugging and inspection area 4 is equipped with a debugging frame, and the packaging area 5 is equipped with a packaging frame.

[0055] The first assembly area 1 is arranged with multiple single-layer transmission stations in sequence, such as Figure 2 As shown, each single-layer transmission platform has multiple conveying rollers 11 arranged in parallel. A lifting rod 12 is provided between adjacent conveying rollers 11. When the lifting rod 12 is lowered, it is lower than the conveying roller 11. When the lifting rod 12 is raised, the gap between the lifting rod 12 and the conveying roller 11 is greater than the thickness of the door or window.

[0056] After the lifting rod 12 is raised, it receives the window frames assembled at the assembly workbench of the frame assembly line 6, and performs tasks such as threading adhesive strips and applying waterproof glue. After completion, the lifting rod 12 is lowered, and the MES system controls the conveyor motor to drive the conveyor roller 11 to transfer the completed window frames to the next process. The lifting of window frames awaiting processing or in the process does not affect the transfer of previously processed window frames. The MES control system controls the movement of the window frames on the single-layer conveyor platform according to the work status of each process, optimizing work allocation. Multiple single-layer conveyor platforms can be set up, corresponding to the frame assembly line 6 on one side. Each single-layer conveyor platform can independently complete its corresponding process requirements without interference.

[0057] In the single-layer transmission station arrangement, the group reversing frame and guardrail are also multiple identical processes carried out simultaneously. The complete set function is set up. The process assembly is carried out through the industrial control board. After scanning the code, the process is transferred. The MES control system will optimize the process and report the work.

[0058] The second assembly area 2 is arranged with multiple double-layer transmission stations 21, such as... Figure 3 As shown, the gap between the upper rubber roller 212 and the lower rubber roller 211 is greater than the thickness of the door and window; a translation belt 213 is provided between adjacent lower rubber rollers 211, and the conveying direction of the translation belt 213 is perpendicular to the conveying direction of the assembly main line.

[0059] The double-layer conveyor table 21 is equipped with upper and lower double-layer conveyor rollers. The lower layer rubber roller 211 is flush with the conveyor roller 11 of the single-layer conveyor table, receives the window frame from the single-layer conveyor table, and is equipped with a translation belt 213 to push the window frame to the discharge end for easy removal. The MES control system controls the movement of the window frame on the lower layer of the double-layer conveyor table 21 according to the work status of each process, optimizing the work allocation. The double-layer conveyor table 21 can be set with multiple sections, corresponding to the pressing line 7, without interference. At the same time, the upper layer rubber roller 212 of the double-layer conveyor table 21 queues up and passes the assembled pressing window frame back to the main line.

[0060] The second assembly area 2 is also provided with a window forming transition frame 22, which is located on the rear side of the double-layer transfer table 21, such as... Figure 5 As shown, the window forming transition frame 22 has a single-layer rubber roller, which is flush with the upper rubber roller 212 of the double-layer transfer table 21. An alignment belt 221 is provided between adjacent single-layer rubber rollers. A positioning baffle is provided on one side of the window forming transition frame 22, and the alignment belt 221 is perpendicular to the positioning baffle. If the window frame deviates, it is corrected by comparing the belt and the positioning baffle. An image recognition device 223 is also provided at the tail of the positioning baffle.

[0061] The window frame transition frame 22 is the intermediate connection between the double-layer transfer station 21 and the intelligent 90° shuttle car 31 (see below for details). It is equipped with an alignment belt 221 and controlled by the MES control system to move the window frame along the positioning edge 222. The QR code is scanned during the transfer using image recognition technology. The MES control system notifies the intelligent 90° shuttle car 31 to perform data docking and production scheduling, and then the window frame enters the parallel automated warehouse 32.

[0062] like Figure 1 As shown, the transfer area 3 is located behind the second assembly area 2. The transfer area 3 is equipped with a shuttle vehicle 31 and an automated storage and retrieval system 32. At least one automated storage and retrieval system 32 is provided. The front side of the shuttle vehicle 31 is connected to the window transition frame 22, and the rear side is connected to the automated storage and retrieval system 32.

[0063] like Figure 6 , Figure 7 As shown, the shuttle car 31 is equipped with a guide rail 311, a base frame 314, and a movable frame 312. The guide rail 311 is perpendicular to the conveying direction of the assembly main line, and the length of the guide rail 311 covers all the automated storage and retrieval systems 32. The base frame 314 is mounted on the guide rail 311 and is slidably connected to the guide rail 311. The movable frame 312 is rotatably connected to the base frame 314. The movable frame 312 is shaped like a "U". The bottom of the upright movable frame 312 is equipped with a push belt 313 for pushing the door frame into the automated storage and retrieval system 32.

[0064] The intelligent 90° shuttle cart 31 receives control commands from the MES control system, flips to a horizontal position, and docks with the window frame transition frame 22 at its feeding end. The intelligent 90° shuttle cart 31 is equipped with a pusher belt 313, which moves the window frame to the discharge end and simultaneously flips the window frame 90° to a near-vertical position. According to the MES commands, it moves to the required placement and docks with the three-dimensional vertical intelligent automated storage and retrieval system 32, moving the window frame into the warehouse.

[0065] like Figure 8 , Figure 9As shown, the automated storage and retrieval system 32 includes multiple storage compartments 321, each of which is parallel to the angle of the erected mobile frame 312. The automated vertical intelligent storage and retrieval system 32 can be set up in multiple sections, accepts instructions from the MES control system, cooperates with the intelligent 90° shuttle vehicle 31, optimizes production according to the later assembly progress, and enters different intelligent storage and retrieval systems 32.

[0066] Meanwhile, the automated vertical storage unit 32 has a storage space 321 corresponding to the later-stage debugging rack. If the debugging rack station is vacant, the window frame can be placed directly in this storage space 321 for easy removal. If this storage space 321 is occupied, the MES control system issues an instruction to place it in another storage space 321. Once the corresponding storage space 321 becomes vacant, the system controls the output of storage space 321 to return the window frame to the intelligent 90° shuttle vehicle 31. The intelligent 90° shuttle vehicle 31 then shuttles the window frame to the storage space 321 corresponding to the debugging rack, where it is stored and ready for subsequent assembly processes.

[0067] One or more automated storage and retrieval systems (AS / RS) 32 are set up, along with corresponding post-processing debugging racks. The MES management system performs optimization calculations based on the tooling status of subsequent processes, controlling the intelligent 90° shuttle trolley 31 to automatically flip the window frame with the crimped edge installed and deliver it into the corresponding AS / RS 32. The intelligent 90° shuttle trolley 31 and the AS / RS 32 are used to adjust the post-processing progress and cycle time management, and multiple post-processing debugging and packaging sections can be separated on the main line.

[0068] like Figure 8 , Figure 9 As shown, a mobile pallet chock device 33 is installed at the bottom of the automated storage and retrieval system 32. The mobile pallet chock device 33 includes a support frame 332 and a transfer belt 331. The transfer belt 331 is mounted on the support frame 332 and slidably connected to it. The transfer belt 331 can rise from the support frame 332 to enter the bottom of the compartment 321 of the automated storage and retrieval system 321, and can move to the bottom of each compartment 321 after the transfer belt 331 is lowered. The mobile pallet chock device 33 cooperates with the intelligent 90° shuttle vehicle 31 according to MES instructions. The transfer belt 331 moves to the corresponding compartment 321, and the transfer belt 331 is raised to realize the entry and exit of the compartment through the window frame.

[0069] like Figure 1 As shown, the debugging and inspection area 4 and the packaging area 5 are arranged sequentially behind the transfer area 3. The debugging and inspection area 4 is equipped with a debugging rack, which corresponds to the automated storage and retrieval system 32. The debugging rack includes a vertical frame 41, as shown... Figure 10 As shown, the angle of the upright frame 41 is parallel to the angle of the storage compartment 321 of the automated warehouse 32. The bottom side of the upright frame 41 has a conveying roller 42, and the side of the upright frame 41 is provided with a clamping device 43 for fixing doors and windows.

[0070] The testing rack is used for assembling window sashes and screens with window frames, as well as assembling and testing matching hardware, and for subsequent inspection. The testing rack features an open design; after the window frame leaves the warehouse, it leans vertically against the rack's facade, with rollers at the bottom for easy movement. After the window frame leaves the warehouse, following the information provided on the control panel, the corresponding window sashes, screens, and hardware are selected from the pre-assembled material cart and assembled and tested as required. Once completed, the assembly is pushed onto the testing rack. After scanning with a barcode scanner, the process is transferred, and the MES control system optimizes the process and reports the completed work.

[0071] The test rack features an open design with a central opening, allowing for separate assembly of the screen sash and window sash on both sides. Products that fail inspection can be directly removed without affecting the subsequent transfer of other frames and sashes (moving, positioning, and clamping). Simultaneously, the packaging module directly retrieves completed products from the test rack according to the instructions of the MES control system, unaffected by other factors.

[0072] Inspectors use barcode scanners to scan the assembled frames and sashes on the testing rack, performing inspections based on the inspection criteria displayed on the industrial control panel by the MES control system. Qualified frames are pushed back to the packaging rack for further testing. Qualified frames are fed back to the MES system via the industrial control system, and then removed from the production line for rework. The MES system will provide feedback and report the issue, facilitating analysis and adjustment of the corresponding door and window quality processes and manufacturing.

[0073] The packaging rack is used for packaging after the frame and sash assembly is completed. Its front end is connected to the debugging rack to be packaged. By scanning the barcode with the industrial control system, the frame and sash to be packaged are selected according to the prompts of the MES control system. The packaging is carried out according to the technical requirements of packaging. After packaging, the printed barcode information is affixed, and the work is reported and stored.

[0074] Based on the process characteristics and requirements of door and window assembly, this invention designs and develops an intelligent door and window assembly line. The assembly process combines sub-line assembly with main line assembly, while the main line implements separate vertical transport to ensure processing within the same process. An intelligent automated warehouse (32 warehouses) is set up to provide material matching and adjust the cycle time, preventing processing timeouts and errors in individual processes from affecting the operation of the entire assembly line. This ensures the effective implementation, data statistics, and feedback of the MES control system, thereby achieving paperless processing and avoiding material waste caused by errors during assembly.

[0075] This invention effectively integrates data between doors and windows and the ERP system, and combines the MES control system with actual assembly. It ensures that various door and window types do not interfere with each other during mixed assembly, and allows for timely adjustment of processes in case of emergencies or accidents, thus enabling better implementation of smart factory practices.

[0076] This invention employs QR code feedback, industrial control dashboards, and other technologies, utilizing IoT data analysis, detection, and adjustment to ensure seamless coordination between workshop processes, prevent downtime, and achieve paperless office operations and automatic work statistics.

[0077] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
