[0001] This invention relates to the field of automated production and manufacturing technology, and more specifically, to a part rework control method, a rework control system, and a storage medium. Background Technology

[0002] With rising labor costs, fully automated machining production lines have quietly replaced manual labor, creating "lights-out factories." This means there are no workers on the production line, only manual operation at off-line rework stations. Currently, while processing equipment on the production line can remove defective parts, for large parts with many characteristic dimensions, manually locating anomalies during rework is inefficient and prone to errors, impacting rework efficiency. Furthermore, the production line involves mixed production of multiple machine models, and the parts produced by different models vary. Accurately transporting reworked parts to their destination is also a significant challenge. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a part rework control method, a rework control system and a storage medium, which can improve the low efficiency of rework parts and the problem of not being able to accurately transport the reworked parts to the destination location.

[0018] Upon receiving an operation instruction indicating that the content in the confirmation interface has been verified, the robot is controlled to transport the first rack containing the part to the production station or scrap area corresponding to the part, based on the rework information.

[0019] In conjunction with the first aspect, in some optional embodiments, the step of controlling the robot to transport the first rack containing the part to the production station or scrap area corresponding to the part, based on the rework information, includes:

[0020] When the repair information indicates that the part is scrapped, the robot is controlled to transport the first rack containing the part to the scrap area corresponding to the part.

[0021] When the rework information indicates that the part is qualified, the robot is controlled to transport the first rack containing the part to the production station corresponding to the part.

[0022] In conjunction with the first aspect, in some alternative embodiments, before acquiring the identification information pre-set on the part via a scanning device, the method further includes:

[0023] When an abnormality is detected in a part during the production process, the part is placed in a second rack located at a designated position, and the abnormality information corresponding to the part is uploaded to the server. The abnormality information is associated with the part's number.

[0043] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In the description of this application, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Please refer to Figure 1 This application provides a method for controlling part rework, which can be applied to a rework control system, and the rework control system executes or implements the steps of the method. The rework control system may include a control device, which includes a processor and a memory coupled together. The memory stores a computer program, and when the processor executes the computer program, the rework control system can perform the corresponding steps in the following part rework control method.

[0045] In this embodiment, the rework control system may further include processing equipment on the production line, a server for storing data, a robot for transporting material racks, and lifting devices for loading or unloading materials. The processing equipment can process parts and detect anomalies in the parts. The parts can be large machined parts; for example, in the production of vehicles, the parts can be, but are not limited to, door sheet metal parts, body floor panels, hoods, and other workpieces.

[0046] In this embodiment, the control device can be an industrial computer, which can control the operation of the robot and the lifting device. The robot can be an Automated Guided Vehicle (AGV).

[0047] Please refer to this again. Figure 1 The method for controlling parts rework may include the following steps:

[0048] Step 110: When a defective part is transported to the rework station, the identification information pre-set on the part is obtained by scanning equipment;

[0049] Step 120: Obtain the abnormal information associated with the identification information from the server as the current abnormal information of the part;

[0050] Step 130: When completing the rework process of the part based on the current anomaly information, upload the rework information of the part to the server;

[0051] Step 140: Place the repaired part into the first rack corresponding to the part;

[0052] Step 150: Upon receiving a first operation instruction for transporting the first material rack, based on the rework information, control the robot to transport the first material rack containing the part to the production station or scrap area corresponding to the part.

[0053] The steps of the parts rework control method will be explained in detail below:

[0054] Before the parts reach the rework station, they need to be processed by the corresponding processing equipment at the production station.

[0055] Prior to step 110, the method may further include:

[0056] Step 101: When an abnormality is detected in a part during the production process, the part is placed in the second rack located at the designated position, and the abnormality information corresponding to the part is uploaded to the server. The abnormality information is associated with the part's number.

[0057] Step 102: When a second operation instruction for transferring the second material rack is received, the robot is controlled to transport the second material rack to the designated rework area, wherein at least one of the parts is placed on the second material rack.

[0058] Step 103: When the robot transports the second rack to the rework area, it removes the parts from the second rack and places them at the rework station.

[0059] In step 101, the processing equipment on the production line can automatically detect whether there are any abnormalities in the parts during the production process. Abnormalities may include, but are not limited to, parts where the assembly torque is outside the set torque range, or parts where the opening size is outside the set size range. The method for detecting abnormalities is conventional and will not be described in detail here.

[0060] When an anomaly is detected in a part during production, the production equipment or a lifting device can place the abnormal part onto a second rack. Additionally, the processing equipment can upload the detected anomaly information to a server. This anomaly information is linked to the part's serial number, facilitating subsequent retrieval of the anomaly information from the server. For easy differentiation, each part is assigned a unique part number, and each rack is also assigned a unique rack number.

[0061] In step 102, the second rack can hold one or more parts. The processing equipment can detect the number of parts placed on the second rack, and the control equipment can obtain this number from the processing equipment. When the number of parts reaches a specified quantity, the control equipment generates a second operation command. In other embodiments, the processing equipment can be equipped with a physical button for operator activation. The operator can press this button to call the robot. That is, after pressing the button, the operator can generate a second operation command, and then the control equipment sends a control command to the robot, causing the robot to travel to the designated position of the second rack and automatically transport the second rack containing the parts to the rework area.

[0062] In step 103, after the robot transports the second rack to the rework area, the control equipment can control the lifting devices in the rework area to divert the parts on the second rack to the corresponding unloading points. Multiple unloading points can be set, for example, unloading point A, unloading point B, unloading point C, and scrap unloading point D. Unloading points A, B, and C can be used as rework stations. Maintenance personnel can inspect and repair abnormal parts at these rework stations.

[0063] In step 110, the identification information can be a QR code or a barcode. The scanning device can be a barcode scanner. The scanning device can obtain the part number information by scanning the QR code or barcode.

[0064] In step 120, the control device can obtain the part number information from the scanning device, and then, based on the part number, retrieve the abnormal information pre-associated with that number from the server, and use it as the current abnormal information for the part. This abnormal information is the information uploaded in step 101.

[0065] The method further includes the following steps: Between obtaining the anomaly information associated with the identification information from the server in step 120 and uploading the rework information of the part to the server in step 130.

[0066] The display screen shows the abnormal information, and a function switch shows the rework operation file corresponding to the part and the abnormal information. When the function switch is turned on, the display screen is used to display the operation content of the rework operation file.

[0067] In this embodiment, the rework station is equipped with a display screen that is communicatively connected to the control equipment. This display screen can show abnormal information about the parts. This allows maintenance personnel to quickly locate the abnormal part based on the abnormal information and perform repairs on that part.

[0068] In this embodiment, operation files for each type of part under different abnormal conditions may be pre-stored in the storage module of the control device. An operator can click the function switch of the operation file on the display screen to make the display screen display / play the operation content of the operation file, which facilitates the operator to perform standardized operations. Wherein, the operation file may be, but not limited to, operation videos, document files, etc.

[0069] In step 130, an input module (such as a mouse, a keyboard, a touch screen) may be externally connected to the display screen, and the rework information of the part may be manually input by the operator through the input module and uploaded to the server. In this way, it can replace the scenario of recording rework information through paper documents, realize cloud storage of data, and help improve the security of data storage. Wherein, the content of the rework information may include, but is not limited to, qualified parts, scrapped parts, etc., which can be flexibly determined according to actual conditions.

[0070] Before step 140 of placing the reworked part into the first material rack corresponding to the part, the method further includes:

[0071] When the reworking process of the part is completed based on the current abnormal information, acquiring the part information of the part and the material rack information of the first material rack;

[0072] judging whether the part information matches the material rack information;

[0073] when the part information does not match the material rack information, sending out prompt information representing material placement error;

[0074] when the part information matches the material rack information, writing the part information of the part into the electronic tag of the first material rack, and executing the operation content of step 140 of placing the reworked part into the first material rack corresponding to the part.

[0075] In this embodiment, the part information may include a part number, and the material rack information may include a material rack number. The server or the control device predefines a binding relationship between material racks and parts, and the binding relationship may be that the part number is associated / bound with the material rack number. This means that a part cannot be placed on a material rack that has no binding relationship with it.

[0076] Understandably, when there is a binding relationship between the part number and the material rack number, it indicates that the part information matches the material rack information, meaning the part is placed on the correct material rack. When there is no binding relationship between the part number and the material rack number, it indicates that the part information does not match the material rack information, meaning the part is placed on the wrong material rack, and a correct material rack needs to be reselected to place the part.

[0077] It should be noted that the electronic tag can be an RFID (Radio Frequency Identification) tag.

[0078] In step 140, after a part is reworked, different parts may correspond to different racks, and these racks are typically transported to different parts of the production line. Placing the reworked part into the first rack corresponding to it helps to place the part into the correct rack.

[0079] Step 150 may include:

[0080] Upon receiving the first operation instruction for transporting the first material rack, a confirmation interface pops up on the display screen, and the content displayed on the confirmation interface includes the quantity and number of the parts.

[0081] Upon receiving an operation instruction indicating that the content in the confirmation interface has been verified, the robot is controlled to transport the first rack containing the part to the production station or scrap area corresponding to the part, based on the rework information.

[0082] In this embodiment, the first operation command can be generated by the control device when the number of parts on the first shelf reaches a specified quantity, or it can be generated by the user triggering the transport switch. The function of the transport switch is similar to the physical button used to call the robot described above.

[0083] A confirmation interface pops up on the display screen, allowing maintenance personnel to re-verify the parts and quantities on the first rack, thereby improving the accuracy of parts transportation.

[0084] In addition, when the operator presses the transport switch, the robot can reach the location of the first material rack based on the first operation command, and then perform the task of loading and transporting the first material rack.

[0085] In step 150, based on the rework information, the robot is controlled to transport the first rack containing the part to the production station or scrap area corresponding to the part, including:

[0086] When the repair information indicates that the part is scrapped, the robot is controlled to transport the first rack containing the part to the scrap area corresponding to the part.

[0087] When the rework information indicates that the part is qualified, the robot is controlled to transport the first rack containing the part to the production station corresponding to the part.

[0088] Please refer to the reference. Figures 2 to 7The implementation process of the method will be illustrated below with examples:

[0089] Please refer to Figure 2 ,like Figure 2 The diagram shows the parts operation flow. Production line 1 can include automated processing equipment, assembly equipment, and testing equipment. When a part malfunctions during production, the equipment automatically places the part into a rack. Each rack can hold multiple parts. When a rack is full or needs to be transferred in advance, an AGV automatically sends the rack (including parts) to the off-line rework area 8. Rework area 8 can be equipped with manual lifting tools, allowing operators to remove the malfunctioning parts from the racks to the rework station for repair by maintenance personnel. After repair, the parts are sorted and placed in racks at unloading points A, B, and C using lifting tools. Finally, the AGV is notified to transport qualified parts back to the fully automated production line 1. Defective parts are placed at the defect unloading point D, awaiting further processing. In this way, this solution can aggregate malfunctioning parts processed by multiple automated devices into one place for rework, and then automatically return them to their respective devices after repair.

[0090] Please refer to Figure 3 This is a schematic diagram of a fully information-based network. Production line 1 may include industrial control computers for inspecting and assembling parts, and PLCs (Programmable Logic Controllers) for processing and assembling parts. When a part malfunctions, the automated equipment in production line 1 will upload the abnormal production data to the factory-level digital base 2 via the network. The factory-level digital base 2 can function as an industrial control computer or a server. If it functions as an industrial control computer, it can send part data to the server via the network for cloud storage. A rework management system 3 is deployed on the factory-level digital base 2, which can collect abnormal production data and generate an abnormal data summary table. Manual personnel use a QR code scanner 5 to scan the part's QR code for matching. The abnormal information is displayed on the rework industrial control computer's WEB interface 4, facilitating operator intervention and recording rework process information. After rework, the part is loaded into a rack, and the part information can be written into the rack's RFID 7 via an RFID reader 6. After the rack returns to the production line, the equipment can automatically identify the part by reading the rack's RFID 7. In this way, a complete information loop can be achieved, the entire process can be electronic, and there is no need for paper documents to be transmitted.

[0091] Please refer to Figure 4 This is a flowchart illustrating the rework process. After the part arrives at the rework station, the operator uses a QR code scanner (5) to read the QR code. That is, QR code 81 is read. This opens the rework industrial control computer's web interface (4), which can be seen in the following diagram. Figure 5A schematic diagram of the rework information retrieval interface. A QR code is affixed to the part, which is scanned by a manual handheld QR code scanner 5. After the code is recognized, the part information (such as workpiece number or part number) is filled into the corresponding pane 41.

[0092] Furthermore, the abnormal information is automatically matched with 82. After the part number is identified, it will be automatically matched as follows: Figure 5 The abnormal information 43 shown indicates that the abnormal part data of each device is automatically collected and summarized by the rework management system 3 in the background, and the abnormality type of the processing station is automatically displayed, which can clearly show which station the part came from and what type of abnormality it is.

[0093] Furthermore, abnormal data retrieval 83. When there are specific values ​​for the abnormal part, such as assembly torque, detection value, etc., the system will automatically retrieve the abnormal data 42 of the corresponding part from the corresponding stored equipment database and display it on the WEB interface 4 of the rework industrial control computer for easy viewing by the operator.

[0094] Furthermore, the job file retrieval function (84) is implemented. A function switch / button for job file retrieval is set in the rework industrial control computer's WEB interface (4). When needed, the operator can click the "Job File Retrieval" button (45). After matching in the background, the corresponding abnormal workstation rework operation manual is retrieved. The operator can then perform the rework step-by-step according to the job file. Once the operator is proficient, clicking "Job File Retrieval" (45) is no longer required; in this case, the operation manual interface will not pop up.

[0095] Furthermore, 85 parts are reworked. Based on the anomaly information and operating instructions, the parts are manually reworked and confirmed, and the rework results are entered into the corresponding window. The appropriate option is selected at the judgment point. Figure 5 The drop-down menu 43 shows the judgment status (the drop-down options can be configured in the background for easy future expansion). In the remarks 44, you can manually fill in the rework operation record. After completing the operation, click the confirmation button 46 to complete the operation and submit the information.

[0096] Furthermore, select 86 as the unloading point. Based on the rework results, define return stations for unloading points A, B, and C. As an example: Unloading point A is defined as returning to OP10 (after definition, this rack can only hold OP10 parts; the bound part type can be modified after replacing with a new rack). If a qualified OP10 part is reworked, the part is lifted into the rack at unloading point A using a lifting device.

[0097] Furthermore, scan QR code 87. When the rack is full or the model needs to be changed, a person manually scans the QR code using a handheld barcode scanner 5. The number is then entered into the corresponding pane. If the material is placed incorrectly, a prompt will appear on the WEB interface 4 of the rework control computer, reminding the user to replace the rack. If the material is placed correctly, it indicates that the rack and part number have been successfully linked.

[0098] Furthermore, RFID is written to step 88. The material rack has RFID tags for automatic reading on the production line. Before the material rack leaves, manual intervention is required to write RFID information; the written content is the part number obtained from reading the QR code (step 87).

[0099] Next, call AGV89. The operator calls the AGV via a button to return the rack containing the parts to the automated production line. Before the call is successful, a confirmation screen will pop up. The operator reconfirms the quantity and part number. Once confirmed, the AGV call is complete. Wait for the AGV to automatically return the rack to the production line or inventory area.

[0100] In this embodiment, a fully information-based network design is adopted, which is evident. Figure 3 All information generated by the equipment is stored in the factory-level digital base 2, employing a factory-grade data processing and storage solution, ensuring enhanced data security. It can be viewed anytime, anywhere within the company. The rework management system 3 is deployed on the factory-level digital base 2 using a cloud-based (non-local) deployment, operated via the rework industrial control computer's WEB interface 4. Information is directly accessible, and rework operation information is stored in the cloud, eliminating concerns about data loss due to power outages or hardware damage. Part numbers are bound to the material rack RFID tags, and RFID data is transmitted back to the production line equipment, breaking away from traditional paper-based transmission methods. This achieves a closed-loop information flow from equipment back to equipment, making it more environmentally friendly, safer, and traceable.

[0101] In this embodiment, an abnormal processing information matching design is adopted, and the rework information is accurately transmitted, which can significantly improve the operational efficiency. The abnormal information of each device is extracted and summarized in real time in the background by the rework management system 3. After scanning the code on site, the abnormal information is automatically matched and displayed on the screen, which is highly efficient. It can avoid the efficiency loss caused by manually searching for abnormal information, and can also solve the cumbersome traditional paper record-keeping, which is more environmentally friendly and reliable.

[0102] In this embodiment, abnormal feature data retrieval and connection can be achieved. For parts with detailed abnormal feature data, the abnormal data 42 of the corresponding equipment on the production line is automatically connected through the abnormal information workstation number to retrieve the latest result data of the equipment at that workstation. The solution adopted is to directly connect to the field equipment database, which can ensure that the data is up-to-date and avoid the delay caused by synchronizing the database to the server and then to the field equipment. The data adopts a database table design, which does not require secondary parsing. It can be retrieved and viewed directly by matching the part number, which is simple and efficient.

[0103] In this embodiment, an online workflow document association design is adopted. Traditional workflow documents are printed on paper and posted next to the equipment. They are often lengthy and inconvenient for operators to view precisely, and updates do not allow for immediate on-site guidance. This invention's rework solution incorporates workflow document management in the background, allowing for one-click access to the site via the rework management system 3. Version management and online transmission of workflow documents improve maintainability, timeliness, and traceability. Furthermore, modular matching is implemented for different workstations. After matching abnormal workstations based on part numbers, the corresponding workflow documents are automatically matched. These documents can be retrieved manually by clicking the workflow document retrieval button 46, eliminating the need for manual searching and ensuring high efficiency and accuracy.

[0104] In this embodiment, a flexible rework return rack design is adopted. After rework, the parts need to be classified and placed, resulting in multiple workstation states. If each unloading point is fixed, many unloading points would be required, occupying a large area, and the range of the hoisting rails would also be large, leading to a significant investment. The non-fixed flexible unloading point design adopted in this invention can set up unloading points for 3 qualified parts (e.g., Figure 2 The diagram shows unloading points A, B, and C, and a scrap unloading point D. When qualified parts are unloaded, they need to be returned to the production line station. When placing them into the material rack, the station to return to can be selected. This can flexibly handle situations with a large number of stations and reduce the number of unloading points.

[0105] As an example, please refer to 6. When the material is placed into the feed port A, and the drop-down menu is selected to return to station OP10, you can refer to the content of the row containing return station 47, which will not be repeated here. Using the drop-down menu method, the name of the return station can be configured in the background, which has the flexibility for future expansion.

[0106] In this embodiment, an intelligent error-proofing scheme is adopted. Manual operation carries the risk of misplacement. This invention incorporates multiple intelligent error-proofing measures. First, when a part is placed in the rack and the rack is full or needs to be changed, a handheld QR code scanner 5 scans each part in the rack individually to fill the missing parts. Figure 6 If a part placed in grid 48 does not match the selected return station 47, the system will alarm to prompt the operator to change the unloading point. Second, click the RFID write button 49 to complete the write operation. Before writing, clear the RFID content. If the write is successful, button 49 will display green; otherwise, it will display red, to prevent incorrect RFID information on the material rack. Third, during execution... Figure 4 When the action in the middle calls AGV89, such as Figure 7 As shown, a confirmation dialog box pops up on the display screen of the rework station. The operator will then reconfirm whether the rack number, part number, and part quantity are correct, which can prevent the part QR code from being missed, scanned repeatedly, or other issues.
