The production management system is connected to the assembly instruction system and generates product assembly information using the product identity information. The production management system tracks the position of the product on the production line in real time, generates current workstation information and process completion information, and also generates early warning information when the production line is abnormal. The product assembly information, current workstation information, process completion information, and early warning information all contain the product identity information and are transmitted to the assembly instruction system by the production management system. The assembly instruction system is connected to one or more of the display input systems. Using the current workstation information, it selects the corresponding workstation assembly information from the product assembly information, and then combines the process completion information and the warning information to generate display information. The assembly instruction system selects the corresponding display input system and sends the display information. The display input system displays the information.

[0005] Furthermore, the display input system receives manual input, generates workstation control information, and then transmits it to the assembly instruction system; the workstation control information includes the display identity information corresponding to the display input system; The assembly instruction system processes the workstation control information, selects the corresponding workstation assembly information from the product assembly information, and then combines the process completion information and the warning information to generate display information, which is then sent to the display input system corresponding to the display identity information.

[0006] Furthermore, the production management system includes a vehicle tracking module, a process path module, an early warning module, an order management module, and a first communication module; the vehicle tracking module, the process path module, the early warning module, and the order management module are all connected to the first communication module; The vehicle tracking module monitors the product's location and generates the current workstation information and the process completion information; the early warning module monitors the production line status and generates early warning information when the production line is abnormal; the product assembly information includes the component information and process information of the product at each workstation; the component information is managed by the order management module, and the process information is managed by the process path module. The current workstation information, the process completion information, the early warning information, and the product assembly information are all transmitted to the assembly instruction system through the first communication module.

[0007] Furthermore, the assembly instruction system includes an assembly management module, a display management module, a second communication module, and a third communication module; the display management module, the second communication module, and the third communication module are all connected to the assembly management module.

The assembly management module stores the correspondence between the product identity information and the display identity information. It also selects the workstation assembly information from the product assembly information by combining the current workstation information and the workstation control information, and identifies the corresponding display input system using the correspondence. Then, using the display management module and the process completion information, it generates the display information and sends it to the selected display input system.

[0008] Furthermore, the display input system includes a display module, an input module, and a fourth communication module; the fourth communication module is connected to the display module, the input module, and the identity recognition system. The display module is an e-ink screen or a flexible screen, used to display the display information transmitted by the fourth communication module; the input module is a button or a touch screen, used to respond to manual input, generate the workstation control information, and transmit it through the fourth communication module. The identity recognition system includes a camera or barcode scanner for reading the product identity information, and also reads the displayed identity information from the display module through the fourth communication module. The present invention also includes a production method using the above-described electronic screen-based production assembly guidance system, comprising the following steps: Step S10: The product enters the production line and completes the logical binding. The assembly instruction system records the binding relationship between the displayed identity information and the product identity information; the production management system generates the product assembly information, sends it to the assembly instruction system, and then saves it. Step S11: The product completes physical binding; Using a fixing device, the identity recognition system and the display input system are fixed to the product and move along the production line with the product, passing through each workstation; Step S12: At each workstation, the display input system displays the assembly information of that workstation; The assembly instruction system uses the current workstation information sent by the production management system to select the workstation assembly information from the product assembly information, and combines it with the process completion information to generate the display information, which is then transmitted to the corresponding display input system for display. Step S13: The product is installed at the current workstation; if the current workstation is the last workstation, proceed to step S14, otherwise proceed to step S12. Step S14: The product logic is unbound; The assembly instruction system releases the binding relationship, clears the product assembly information, and notifies the display input system to display blank information and go into sleep mode. Step S15, the product is physically unbound; Release the fixing device and remove the identity recognition system and the display input system from the product; Step S16: Transport the disassembled identity recognition system and display input system to the production line entrance, proceed to step S10, until all products are produced.

[0009] Furthermore, in step S10, the specific steps of logical binding also include: In step S100, the identity recognition system reads the display identity information from the display input system, reads the product identity information from the product, and transmits it to the assembly instruction system; In step S101, the assembly instruction system pairs and saves the displayed identity information and the product identity information to form the binding relationship; the assembly instruction system forwards the product identity information to the production management system.

Step S104: The assembly instruction system saves the product assembly information.

[0010] Furthermore, step S14 specifically includes: Step S140: After the production management system recognizes that the product has come off the production line, it generates off-the-production information containing the product's identity information and sends it to the assembly instruction system. Step S141: After receiving the offline information, the assembly instruction system uses the binding relationship to find the corresponding display input system, then unbinds the binding relationship, deletes the product assembly information corresponding to the product identity information, generates unbinding information, and sends it to the corresponding display input system. Step S142: After receiving the unbinding information, the display input system displays blank information; In step S143, the display input system enters a low-power state.

[0011] Furthermore, the production process of the product also includes an early warning method, comprising the steps of: Step S20: The early warning module in the production management system monitors the production line and generates the early warning information when the production line is abnormal; the early warning information includes the product identity information. Step S21: The early warning module sends the early warning information to the assembly instruction system; Step S22: The assembly instruction system combines the early warning information with the workstation assembly information to generate the display information, and then uses the binding relationship to obtain the corresponding display input system, and transmits the display information to the corresponding display input system; Step S23: The display input system displays the workstation assembly information and the warning information at the same time.

Implementation

[0015] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0016] Please see Figure 1 The present invention discloses a production assembly guidance system based on an electronic screen. In a preferred embodiment, it consists of a production management system 100, an assembly instruction system 200, a display input system 300, and an identity recognition system 400.

[0017] The production management system 100 is responsible for coordinating the production deployment of the entire production line, including workstation management, process management, order management, and production management. It provides product assembly information corresponding to the products going online, current workstation information for the products, process completion information for each workstation, and early warning information for production line anomalies. The product assembly information, current workstation information, and early warning information all contain product identification information, which is transmitted from the production management system 100 to the assembly instruction system 200. When a product goes online, the production management system 100 obtains the product identification information from the identification system 400, thereby generating product assembly information corresponding to that product and transmitting it to the connected assembly instruction system 200. The assembly instruction system 200 and one or more display input systems 300 utilize the product assembly information provided by the production management system 100 to integrate and generate an electronic assembly sheet for the corresponding product going online. This sheet includes the process flow information and component information required for each workstation. Then, the assembly instruction system 200 obtains the location of the products going online from the production management system 100. Based on the current workstation information of the products, it selects the corresponding workstation assembly information, combines it with early warning information, generates display information, and delivers it to the corresponding display input system 300 connected to it for display. The display input system 300 and the identity recognition system 400 are fixed together. The identity recognition system 400 is fixed to the camera or barcode scanner of the display input system 300 and can obtain the product identity information of the products going online using text recognition, QR code recognition, or barcode recognition. The identity recognition system 400 is connected to the display input system 300, reads the display identity information of the display input system 300 using the communication interface of the display input system 300, and then transmits the obtained product identity information (identifying the product) and display identity information (identifying the display input system 300) to the assembly instruction system 200 through the connected display input system 300. The assembly instruction system 200 pairs and saves the display identity information and product identity information, forming a binding relationship, and then forwards the product identity information to the production management system 100. The display input system 300 and the identity recognition system 400 are fixed together as a single unit, allowing them to be detachably fixed to the product using a mounting device installed on the display input system 300. The mounting device is a suction cup, making it easy to install and remove from the product.

[0018] Furthermore, the display input system 300 can also receive manual input to actively adjust the current display content. After manual operation, the display input system 300 generates station control information and sends it to the assembly instruction system 200. The station control information contains display identity information corresponding to the display input system 300, enabling the assembly instruction system 200 to identify from the multiple connected display input systems 300 which the manual input came from. Upon receiving the station control information, the assembly instruction system 200 combines the station control information and the current station information, selects a suitable new station assembly information (e.g., the previous or next station) from the product assembly information, and then combines it with process completion information and warning information to generate new display information, which is then sent back to the display input system 300 that sent the station control information to update the display content.

[0019] The production management system 100 includes a vehicle tracking module 101, a process path module 102, an order management module 103, a first communication module 104, and an early warning module 105. The process path module 102 is connected to the vehicle tracking module 101, and the vehicle tracking module 101 is connected to the order management module 103.

[0020] The vehicle tracking module 101 is used to determine the specific location of the product on the production line. It utilizes the online and offline sensing sub-modules to determine the product's start and end points on the production line, and also uses various sensors installed at each workstation to determine the specific workstation on the production line, providing current workstation information and process completion information. The process path module 102 provides the product's technological flow, i.e., the specific processes that the product needs to complete at each workstation, and also provides process completion information. The order management module 103 provides the product's component information, i.e., which components a product needs to produce on the production line. Once the product is online, combining the information provided by the process path module 102 and the order management module 103, product assembly information can be generated for that product, i.e., which workstations the product needs to pass through, the components used at each workstation, and the processing steps, etc. The product assembly information is then transmitted to the assembly instruction system 200 via the first communication module 104. As the product moves along the production line, the vehicle tracking module 101 continuously updates the product's current workstation information and transmits it to the assembly instruction system 200 via the first communication module 104. This allows the assembly instruction system 200 to select the correct workstation assembly information from the product assembly information for final display. At each workstation, the vehicle tracking module 101 also continuously updates the product's process completion information and transmits it to the assembly instruction system 200 via the first communication module 104. The early warning module 105 monitors the production status of the production line. When an anomaly occurs, the early warning module 105 generates an early warning message and forwards it to the assembly instruction system 200 via the first communication module 104. The assembly instruction system 200 then controls the display input system 300 to display the early warning message.

[0021] The assembly instruction system 200 serves as the link between the display input system 300, the identification system 400, and the production management system 100, and is the core logic of this design. The assembly instruction system 200 collects information from the production management system 100, then, based on the type of the input system 300, generates corresponding display information, including assembly information for each workstation (workstation assembly information), the process completion status for each workstation (process completion information), and warning information, which is then delivered to the display input system 300 to prompt the workers. Simultaneously, input information from the display input system 300 and the identification system 400 is also forwarded to the production management system 100 through the assembly instruction system 200.

[0022] The assembly instruction system 200 includes an assembly instruction management module 201, a display management module 202, a second communication module 203, and a third communication module 204. The assembly instruction management module 201 and the display management module 202 are interconnected. The assembly instruction management module 201 receives and saves product assembly information from the production management system 100, while the display management module 202 saves the binding relationship between the product identity information of each product and the display identity information of its corresponding display input system 300. Upon receiving current workstation information from the production management system 100, the assembly instruction management module 201 extracts the product identity information from it and compares it with the product identity information contained in the product assembly information to select the product identity information corresponding to the product. Then, combined with the current workstation information, it selects the workstation assembly information describing the assembly information of the current workstation. Then, the assembly instruction management module 201 uses the binding relationship in the display management module 202 to find the corresponding display input system 300, thereby knowing which display input system 300 the current information needs to be displayed on, as well as the type of display input system 300, and thus adjusts the format of the display content, etc. Finally, after combining the workstation assembly information, process completion information and warning information, it generates display information and sends it to the selected display input system 300.

[0023] The assembly instruction management module 201 is connected to both the second communication module 203 and the third communication module 204. It communicates with the production management system 100 via the second communication module 203 and with one or more display input systems 300 and an identification system 400 via the third communication module 204, receiving workstation control information and displaying identification information. The display management module 202 is only connected to the third communication module 204, obtaining information from the display input systems 300 through the third communication module 204.

[0024] The display input system 300 includes a display module 301, an input module 302, and a fourth communication module 303. The display module 301 and input module 302 are respectively connected to the fourth communication module 303. The display module 303 displays information transmitted from the assembly instruction system 200 via the low-power communication module 303; it can be an e-ink screen, a PDA, or a flexible display. The display module 301 also has the ability to enter a low-power state, automatically entering this mode after decoupling from the system and product logic to save energy. The input module 302 consists of multiple buttons, such as left and right buttons. At the workstation, workers can use the left and right buttons to switch between the assembly information of the previous or next workstation. The input module 302 can also be implemented as a touchscreen integrated with the display module 303, working in conjunction with the display module 303 to display a soft keyboard for information input. Based on user input, the input module 302 generates workstation control information and sends it to the assembly instruction system 200 via the fourth communication module 303, thereby enabling switching between different workstation assembly information and can also be used to eliminate warning information, etc. The fourth communication module 303 is also used for external connection to the identity recognition system 400. During the logical binding phase, the identity recognition system 400 reads the display identity information used to identify the current display input system 300 through the fourth communication module 303.

[0025] Please see Figure 2 The present invention also includes a production method utilizing an electronic screen-based production assembly guidance system, a preferred embodiment of which includes the following steps: Step S1: Product launch, which involves logically binding the product with the display input system and the identity recognition system.

[0026] The assembly instruction system records the binding relationship between display identity information and product identity information. Simultaneously, the production management system generates product assembly information, sends it to the assembly instruction system, and saves it, thus completing the logical binding. After this process, the display input system (identified by display identity information) and the product (identified by product identity information) are mutually associated. Then, product-related information in the production management system can be forwarded to the corresponding display input system for display, and similarly, input from the display input system can be mapped to the corresponding product information.

[0027] Step S2, physically bind the product to the production assembly guidance system.

[0028] Using a fixing device, the identification system and display input system are fixed to the product and move along the production line with the product, passing through different workstations.

[0029] The fixing device is a detachable fixing method, such as a suction cup. It can easily complete the physical binding at the front end of the production line, thereby guiding the assembly process of each subsequent workstation. After the product comes off the line, the display input system and identification system can be separated from the product for easy reuse.

[0030] Step S3: At each workstation, the display input system displays the workstation assembly information corresponding to the current workstation.

[0031] Workstation assembly information refers to the assembly guidance information at a single workstation. It is extracted from the product assembly information by the assembly instruction system and then sent to the display input system for presentation. As the product moves along the production line, the production management system monitors it in real time and updates the current workstation information of the product to the assembly instruction system. Based on the current workstation information, the assembly instruction system selects the corresponding workstation assembly information from the product assembly information.

[0032] The displayed information also includes the current installation progress of the product. When a product enters a workstation, its installation progress is "Pending Installation". As workers complete each process at the workstation, the production management system collects process completion information and sends it to the assembly instruction system. The assembly instruction system uses the updated status to update the displayed information, such as displaying "Process XX Completed" or "Installing". When the product completes all processes at a workstation, the assembly instruction system uses the updated status to update the displayed information to "Completed".

[0033] Step S4: At each workstation, switch the workstation assembly information using the display input system.

[0034] In systems that support user input, workers can use the display input system at their workstations to switch the currently displayed assembly information. At this time, the assembly instruction system, in addition to relying on the current workstation information from the production management system, also needs to combine the workstation control information from the display input system to comprehensively generate the workstation assembly information for display.

[0035] Step S5: When the production line malfunctions, display the warning information through the display input system.

[0036] In systems that support production line early warnings, the display input system can display not only the assembly information of the current workstation but also early warning information. In this case, the display information generated by the assembly instruction system will include both workstation assembly information and early warning information. Specifically, the specific display location of the early warning information may vary depending on the different display input system models.

[0037] Step S6: The product is installed at the current workstation. If the current workstation is the last workstation, proceed to step S7; otherwise, proceed to step S3.

[0038] Step S7: Unbind product logic.

[0039] The assembly instruction system unbinds the display identity information from the product identity information, clears the product assembly information, and notifies the display input system to display blank information and go into sleep mode.

[0040] Step S8: Unbind the product physical.

[0041] Release the securing device to detach the identification system and display input system from the product. For example, release the suction cup to remove the identification system and display input system from the product.

[0042] Step S9: Transport the removed identification system and display input system to the production line entrance, proceed to step S1, until all products are produced.

[0043] Please see Figure 3 In this embodiment, the product logic binding process in the production method of the production assembly guidance system based on electronic screens, i.e., the sub-step of step S1, includes the following steps: Step S1a: Read and display identity information and product identity information.

[0044] After a product goes live, the production management system receives the go-live information and then notifies the identification system to read the product's identification information. The identification system (e.g., a camera) reads the product identification information (e.g., by photographing text on the product surface, performing text recognition, and obtaining the product serial number). The identification system then reads the display identification information from the display input system and transmits it to the assembly instruction system via the display input system's transmission interface.

[0045] In step S1b, the assembly instruction system saves the binding relationship and forwards the product identity information.

[0046] After receiving the paired display identity information and product identity information, the assembly instruction system saves the pairing relationship, forming a binding relationship. Then, the assembly instruction system forwards the product identity information to the production management system.

[0047] In step S1c, the production management system generates product assembly information.

[0048] The order management module in the production management system selects the corresponding product's component information based on the product's identity information, and then uses the process path module in the production management system to select the corresponding product's process information. Combining the two, it generates the component information required for all workstations of the product and the process information such as the operation of each workstation, forming the product assembly information corresponding to the product.

[0049] In step S1d, the production management system transmits product assembly information to the assembly instruction system.

[0050] In step S1e, after the assembly instruction system saves the product assembly information, the logical binding is completed.

[0051] Please see Figure 4 In this embodiment, the product logic unbinding process in the production method of the production assembly guidance system based on electronic screen, i.e., the sub-step of step S7, includes the following steps: Step S7a: The production management system sends product off-line information.

[0052] After processing, the product reaches the production line exit. Once the production management system detects the product leaving the line, it sends product exit information to the assembly instruction system. This exit information includes the product's identification information.

[0053] Step S7b: The assembly instruction system is unbound and an unbinding command is sent.

[0054] After receiving product off-line information, the assembly instruction system extracts the product identity information from it. Using this product identity information as a keyword, it locates the corresponding product assembly information and deletes it. Then, leveraging the binding relationships, it finds the corresponding display identity information and uses it to locate the corresponding display input system from multiple display input systems, sending an unbinding command to it.

[0055] In step S7c, after the display input system receives the unbinding command, it clears the currently displayed content and displays blank information.

[0056] Step S7d: The input system is displayed as entering a low-power state.

[0057] Please see Figure 5 In this embodiment, the early warning prompting process in the production method of the production assembly guidance system based on electronic screen, namely the sub-step of step S5, includes the following steps: Step S5a: The early warning module generates early warning information.

[0058] The production management system includes an early warning module that monitors the entire production line process. When an anomaly occurs on the production line, an early warning message is generated. This message includes the identification information of the product involved in the anomaly.

[0059] In step S5b, the early warning module sends the early warning information to the assembly instruction system.

[0060] In step S5c, the assembly instruction system generates display information.

[0061] The assembly instruction system integrates warning information with the original workstation assembly information to generate display information. Then, the system reads the product identity information from the warning information, uses the binding relationship to find the corresponding display identity information, and locates the display input system corresponding to the current product among multiple display input systems, sending the display information to that system. Furthermore, there are multiple ways to integrate warning information and workstation assembly information. For example, warning information and workstation assembly information can be combined and displayed simultaneously. In the event of a serious problem, the warning information overwrites the original workstation assembly information, displaying a warning box above it.

[0062] In step S5d, the display input system presents relevant content to the user based on the displayed information.

[0063] The display input system can contain only station assembly information (when there is no warning information), or display both warning information and station assembly information simultaneously (normal warning), or display warning information as an overlay above the station assembly information (critical warning).

[0064] Please see Figure 6 In this embodiment, the assembly information switching process in the production method of the production assembly guidance system based on electronic screens, i.e., the sub-step of step S4, includes the following steps: Step S4a: Initiate a manual switch work order request at the workstation.

[0065] Users can input work order requests at their workstations using the input module of the display input system. For example, they can switch between workstation assembly information by using left and right buttons, or they can operate on the touch screen by swiping left and right.

[0066] In step S4b, the input module generates station control information (e.g., whether it's the previous or next station) based on user input and sends it to the assembly instruction system. The station control information includes the display identity information of the currently displayed input module.

[0067] In step S4c, the assembly instruction system selects the corresponding product assembly information.

[0068] Using the binding relationship, the corresponding product identity information is found from the displayed identity information, and then the corresponding product assembly information is found using the product identity information.

[0069] In step S4d, the assembly instruction system generates new display information and sends it to the display input system.

[0070] The assembly instruction system combines current workstation information and workstation control information to select new workstation assembly information from the product assembly information. For example, if the current workstation is 2 and a switch information from the previous workstation is received, the current workstation information is set to workstation 1. If the current workstation is 2 and a switch information from the next workstation is received, the current workstation information is set to workstation 3.
