Abstract
Description
Technical Field
[0001] This invention relates to the field of automation technology, and in particular to a control method, detection system, and automated production line for material re-feeding. Background Technology
[0002] In modern manufacturing, fully automated production lines are a key technology for improving production efficiency, ensuring product quality, and reducing manufacturing costs. These systems are widely used in various fields such as automobile manufacturing, electronic assembly, and food processing. To maintain the efficient operation of the production line and ensure the quality of the final product, timely identification and removal of defective products is a crucial aspect of production management. Defective products encountered during the fully automated production process are currently in the state of semi-finished products or scrap. For semi-finished products with minor defects, they can be manually repaired and then reintroduced into the production line for further processing. Because the location of defective products after removal varies, their reintroduction location also differs. Therefore, after repair, products need to be manually placed into different production line sections, requiring manual differentiation. This process cannot be replaced by automated equipment, and the manual input restricts the introduction of intelligent production lines. Furthermore, the manual differentiation process is prone to errors and lacks closed-loop control, thus limiting the yield rate and automation rate of the production line. Summary of the Invention
[0003] The main objective of this invention is to propose a control method, detection system, and automated production line for material re-feeding, aiming to improve the yield and processing efficiency of the automated production line.
[0004] To achieve the above objectives, the present invention proposes a method for controlling material re-feeding, the method comprising:
[0005] Information is read from the input materials being processed;
[0006] When the input material is determined to be a repaired material based on the identifier in the read information, the material is transferred to the corresponding processing section so that the material is processed in the corresponding processing section.
[0007] In one embodiment, the method further includes the following step before the step of reading information from the input material to be processed:
[0008] Inspect the materials being processed in the current work section;
[0009] When a defect is detected in the processed material, a corresponding identifier is written into the information of the processed material, and the processed material with the defect is transferred to the defective product discharge port.
[0010] In one embodiment, the corresponding identifier includes the processing section and the defect type.
[0011] In one embodiment, after the steps of writing a corresponding identifier to the processed material when a defective item is detected, and transferring the processed material with the defective item to the defective product discharge port, the method for controlling material reprocessing includes:
[0012] Identify the type of processed material discharged through the defective product discharge port;
[0013] Based on the identified type, determine whether the processed material is a semi-finished product or a waste product;
[0014] When the material being processed is a semi-finished product, the material being processed is repaired.
[0015] In one embodiment, after the step of repairing the processed material when it is a semi-finished product, the method for controlling the re-feeding of the material includes:
[0016] A repair identifier is written to the processed material that has been repaired. When the processed material is determined to be the repaired material based on the read identifier, the processed material is transferred to the corresponding processing section so that the processed material can be processed in the corresponding processing section.
[0017] In one embodiment, the step of reading information from the input processed material further includes:
[0018] A corresponding identifier is written to the material being processed. When the input material is determined to be a repaired material based on the read identifier, the material being processed is transferred to the corresponding processing section so that the material being processed can complete the processing in the corresponding processing section.
[0019] The present invention also proposes a detection system based on the material re-feeding control method as described in any one of claims 1 to 6, the detection system comprising:
[0020] An information reading device is used to read information from the processed material and output corresponding identification signals;
[0021] A control device, electrically connected to the information reading device, is used to transfer the processed material to the corresponding processing section when the input processed material is determined to be a repaired processed material according to the identification signal, so that the processed material can complete the processing in the corresponding processing section.
[0022] In one embodiment, the detection system includes:
[0023] A detection device is electrically connected to the control device. The detection device is used to detect the processed material and output a corresponding detection signal to the control device.
[0024] An information writing device, wherein the information writing device is electrically connected to the control device;
[0025] The control device is used to control the information writing device to write a corresponding identifier to the processed material when it is determined from the detection signal that there is a defect in the processed material.
[0026] In one embodiment, the detection system further includes:
[0027] A conveying mechanism is used to convey the material to be processed in a horizontal direction, and multiple processing sections are formed in the length direction of the conveying mechanism.
[0028] The section module includes an information reading device, a detection device, and an information writing device.
[0029] The control module is used to control the conveying mechanism to convey the material to be processed to the corresponding processing section according to the identification signal, so that the material to be processed can be processed in the corresponding processing section.
[0030] In one embodiment, the detection system further includes a defective product discharge port, which is disposed on one side of the conveying mechanism;
[0031] The control device is used to control the information writing device to write a corresponding identifier into the processed material when it is determined from the detection signal that there is a defect in the processed material, and to transfer the processed material with the defect to the defective product discharge port.
[0032] In one embodiment, the detection system further includes a refill port, and the conveying mechanism is configured to start from the refill port at one end of itself, which is the starting end of the automated production line;
[0033] The information reading device is used to read information about the processed material fed into the feed port and output a corresponding identification signal to the control device.
[0034] The control device is used to control the conveying mechanism to convey the material to the corresponding processing section when it is determined from the identification signal that the input material is a repaired material, so that the material is processed in the corresponding processing section.
[0035] The present invention also proposes an automated production line, wherein the automated production line includes the detection system described in any of the above claims.
[0036] This invention proposes a control method for material re-feeding. In the material re-feeding control method, the information of the input material to be processed is first read; then, when it is determined that the input material to be processed is a repaired material according to the identifier in the read information, the material to be processed is transferred to the corresponding processing section according to the identifier in the read information, so that the material to be processed can complete the processing in the corresponding processing section.
[0037] In practical applications, after repairing defective products discharged from different positions on the production line, the repaired material is simply placed back into the initial position on the production line. An information reading device on the production line reads the information of the input material and, based on the identifier in the information, determines that the input material is a repaired material. Then, it is transferred to the corresponding processing section according to the identifier in the information, allowing the material to complete its processing and thus finishing the production process that was not completed before repair. Compared to existing technologies where repaired materials are manually placed into the corresponding processing section, the material re-input control method of this invention can automatically read information and direct the material to the corresponding processing section through the information reading device, reducing the error rate. Furthermore, compared to manual differentiation, the identification speed is higher. This improves the yield rate and processing efficiency of the production line. Attached Figure Description

[0045] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0047] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0048] It should be noted that step designations such as S100 and S200 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S200 first and then S100, etc., but these should all be within the protection scope of this application.
[0049] In modern manufacturing, fully automated production lines are a key technology for improving production efficiency, ensuring product quality, and reducing manufacturing costs. These systems are widely used in various fields such as automobile manufacturing, electronic assembly, and food processing. To maintain the efficient operation of the production line and ensure the quality of the final product, timely identification and removal of defective products is a crucial aspect of production management. Defective products encountered during the fully automated production process are currently in the state of semi-finished products or scrap. For semi-finished products with minor defects, they can be manually repaired and then reintroduced into the production line for further processing. Because the location where defective products are removed varies, their reintroduction location also varies. Therefore, after repair, products need to be manually placed into different production line sections, requiring manual differentiation. This process cannot be replaced by automated equipment, and the manual input restricts the introduction of intelligent production lines. Furthermore, the manual differentiation process is prone to errors and lacks closed-loop control, thus limiting the yield rate and automation rate of the production line.
[0050] Therefore, refer to Figure 1 This invention proposes a method for controlling material re-feeding, the method comprising:
[0051] Step S100: Read the information of the input materials to be processed;
[0052] Step S200: When it is determined that the input material to be processed is a repaired material to be processed according to the identifier in the read information, the material to be processed is transferred to the corresponding processing section according to the identifier in the read information so that the material to be processed is processed in the corresponding processing section.
[0053] It is understandable that multiple defective product discharge outlets 60 are set on the automated production line. The defective product discharge outlets 60 are set after the detection device 30 on the production line. After the detection device 30 detects the processed material and determines it to be defective, it is discharged through the defective product discharge outlet 60 of the current processing section, and then the discharged processed material is repaired manually or otherwise.
[0054] In this embodiment, the processed materials are placed on a carrier, which may be affixed with identification codes, such as barcodes or QR codes. To ensure that all processed materials follow the same quality inspection and process control standards and reduce the risk of missed inspections, processed materials discharged from different defective product discharge ports 60, after being repaired, need to be reintroduced into the initial stage of the production line. This can be achieved by setting up a re-injection port 70 at the initial stage. This allows for smoother integration of processed materials into the existing production scheduling and resource allocation mechanisms, reducing interference with the existing production process and improving overall production efficiency. Furthermore, allowing repaired processed materials to be reintroduced into the production line at any stage could increase the risk of confusion with other normally processed materials, affecting production order and quality control. Uniform input from the initial stage helps avoid this confusion and maintains a clear and orderly production process.
[0055] Specifically, an information reading device 10 is installed on the production line to read information about the materials being processed. This involves reading the identification code on the carrier and, based on the read information, determining that the material being processed is a repaired material. Then, the material is transferred to the corresponding processing section for further processing. For example, the information reading device 10 can accurately identify the type and processing status of each material being processed, determine the appropriate processing flow based on the processing status, and transfer the material to the corresponding processing section to complete any processing steps not completed before the repair.
[0056] In practical applications, after repairing defective products discharged from different positions on the production line, the repaired material is simply placed back into the initial position of the production line. The information reading device 10 reads the information of the input material and, based on the identifier in the information, determines that the input material is a repaired material. Then, it transmits the material to the corresponding processing section according to the identifier in the information, allowing the material to complete its processing in the corresponding section, thus completing the production process that was not completed before repair. Compared to the prior art where repaired materials are manually placed into the corresponding processing section, the material re-input control method of this invention can automatically read information and direct the material to the corresponding processing section through the information reading device 10, reducing the error rate. Furthermore, compared to manual differentiation, the identification speed is higher. This improves the yield rate and processing efficiency of the production line.
[0057] In one embodiment of the present invention, reference is made to... Figure 2 The process includes the following steps prior to the step of reading information from the input materials being processed:
[0058] Step S010: Inspect the materials being processed in the current work section;
[0059] Step S020: When a defect is detected in the processed material, a corresponding identifier is written into the information of the processed material, and the processed material with the defect is transferred to the defective product discharge outlet 60.
[0060] The corresponding identifier includes the processing section and the defect type.
[0061] It should be noted that each processing section on the production line is equipped with a corresponding detection device 30, which is located before the defective product discharge port 60 of each processing section. In the normal production process, when the processed material flows into different processing sections, the corresponding detection device 30 will detect the processed material. When the processed material is detected as defective, it needs to be promptly discharged through the defective product discharge port 60 of the current processing section so that the processed material can be manually repaired or automatically repaired by machinery.
[0062] Based on the above embodiments, after the detection device 30 detects the processed material and determines it to be a defective product, which is then discharged through the defective product discharge port 60, the processed material can undergo automated mechanical repair. For example, simple welding errors or component misalignments can be corrected or replaced using a robotic arm equipped with specialized tools. Alternatively, a precision robotic arm can be used in conjunction with tools for grinding, touch-up painting, and bonding for repair, or defects can be eliminated through laser engraving, heat treatment, and other technologies. This not only improves efficiency but also maintains consistent product quality. Whether to implement repair technology depends on several factors, including the type of defective product and the complexity of the repair.
[0063] Therefore, in this embodiment, the step of reading information from the input processed material further includes:
[0064] A corresponding identifier is written to the material being processed. When the input material is determined to be a repaired material based on the read identifier, the material being processed is transferred to the corresponding processing section so that the material being processed can complete the processing in the corresponding processing section.
[0065] Specifically, when the detection device 30 determines that the processed material is defective based on the information on the processed material, it writes a corresponding identifier to the processed material. This identifier includes the processing stage and the type of defective product. For example, the information may include A1, A2, A3, etc., where the letter A represents unrepaired processed material, and the number represents the corresponding processing stage on the production line. Similarly, other letters can be used to distinguish the type of defective product, such as C representing semi-finished product and D representing scrap. If the processed material is completed in the first processing stage, the corresponding identifier A1 is written into the processed material's information. If it is completed in the second processing stage, the corresponding identifier is changed to A2, or A2 is added after A1, resulting in the identifier A1A2. Taking the control device 20 in the third processing stage detecting a defective product as an example, the information writing device 40 writes the corresponding identifier B3 and the type of defective product into the processed material's information based on the detection result of the detection device 30, and then discharges it through the defective product discharge port 60 of the third processing stage. In this process, B is used to distinguish it from the normal flow of material marked A, so that after manual or mechanical repair, the repaired material can be reintroduced into the refill port 70 at the beginning of the production line. The information reading device 10 of each processing section distinguishes whether the material is to be refilled based on the letters A and B. When the material to be processed in the third processing section is reintroduced, the information reading devices 10 of the first and second processing sections read the information of the material and determine that the product needs to be processed in the third processing section. Therefore, the material will be transferred to the third processing section for processing.
[0066] It should be noted that the detection signal output by the detection device 30 and the identification signal output by the information reading device 10 of each processing section are respectively output to the control device 20 of the production line. For example, the control device 20 of the host computer can control the carrier of the processed material to be discharged through the corresponding defective product discharge port 60 according to the detection signal and the identification signal.
[0067] In this embodiment, when the detection device 30 detects a defect, the control device 20 discharges the defective product, and the information writing device 40 synchronously writes the information detected by the detection device 30 into the information of the processed material. The information includes the processing section and the type of defect. As the processed material passes through each processing section, the information writing device 40 sequentially writes the information of the corresponding processing section into the identification code installed on the carrier of the processed material, including the next processing section that needs to be processed. When the repaired processed material is put into the re-feeding port 70, the information reading device 10 installed on each processing section will read the information. When the information reads that it starts with B, it will be assumed to be a re-feeding product. Then, the number after B will be judged. If the number is greater than the number information of this processing section, then this processing section will start processing. If it is less than the number information of this processing section, it means that it has already been processed in this processing section before repair, and the product needs to be flowed into the next processing section empty. This processing section will not process it.
[0068] It is understandable that the information reading device 10 and the information writing device 40 can be integrated into the same device. For example, information reading and writing can be achieved through an RFID system.
[0069] Specifically, a basic RFID system consists of three parts: an electronic tag, a reader, and an antenna. The electronic tag contains a tiny chip and antenna to store unique product identification information (such as product number, processing information, etc.) and to receive / transmit signals. The reader transmits radio waves to the electronic tag via the antenna and receives the signals reflected back from the tag, decoding the data. On the production line, when a product passes through a processing section, the RFID reader installed at that section sends instructions to the RFID tag on the product, writing the current processing section's identification information (such as A1, A2, etc.) and other relevant data into the chip within the electronic tag. This process requires no physical contact and can be completed within milliseconds. Similarly, when a product with an RFID tag passes through the processing section's detection device 30, the reader reads the information from the tag. Based on the read information (such as the unit identifier of a defective product, the unit identifier B and numbers requiring reprocessing after repair), the system automatically makes decisions, such as rejecting the defective product or determining the next processing step for the repaired product.
[0070] Through the above setup, the information reading device 10, information writing device 40, and detection device 30 of the automated production line achieve the identification and classification of reprocessed materials, saving labor costs and improving the identification rate. This improves the processing efficiency of the automated production line. Furthermore, RFID technology, through its wireless communication capabilities, enables unique identification and tracking of each product during automated production, not only enhancing the transparency and flexibility of the production process but also greatly improving the efficiency and accuracy of defective product management and handling.
[0071] In one embodiment of the present invention, reference is made to... Figure 3 After the steps of writing a corresponding identifier to the processed material when a defective item is detected, and transferring the processed material with the defective item to the defective product discharge outlet 60, the control method for material re-feeding includes:
[0072] Step S030: Identify the type of processed material discharged through the defective product discharge port 60;
[0073] Step S040: Determine whether the processed material is a semi-finished product or a waste product based on the identified type;
[0074] Step S050: When the material being processed is a semi-finished product, the material being processed is repaired.
[0075] Based on the above embodiments, when defective products are discharged through the defective product discharge port 60, if automated repair technology is used for repair, it is necessary to read the information of the defective products (processed materials), determine the type of processed materials based on the identifiers in the information, and identify whether they are semi-finished products or waste. Appropriate handling measures should then be taken for semi-finished products and waste. For example, waste needs to be classified according to factors such as material, recyclability, and hazard. Automated production lines can be equipped with sensors and image recognition systems to help quickly and accurately identify waste types. Alternatively, RFID technology can be used, with RFID readers reading the identifiers in the information of the processed materials to determine the type of defective product. This allows for subsequent treatment using appropriate environmentally friendly methods based on the nature of the waste. For example, recyclable materials should be sent to recycling stations for reuse; hazardous waste needs to be handed over to professional institutions for harmless treatment. Semi-finished products can be repaired and then reintroduced into the production line after repair, flowing into the corresponding processing section for further processing.
[0076] Therefore, in this embodiment, after step S050, the method for controlling the re-feeding of materials includes:
[0077] A repair identifier is written to the processed material that has been repaired. When the processed material is determined to be the repaired material based on the read identifier, the processed material is transferred to the corresponding processing section so that the processed material can be processed in the corresponding processing section.
[0078] In this embodiment, inspection personnel collect defective products for manual repair, or the automated production line transports them to a central collection point for automated repair. Repaired materials are marked with a repair identifier, which includes the processing stage requiring further processing. For example, a separate RFID reader / entry device can be used outside the production line. After repair, the product is placed into the RFID reader / entry device, which automatically writes the information from the RFID chip on the product, indicating the processing stage requiring further processing. The repair identifier information is exemplified by B1, B2, B3… with the letter B distinguishing the normally circulating unit identifier A.
[0079] RFID technology is used to automatically identify the types of defective products, facilitating the repair of semi-finished products. After repair, a repair identifier is written into the RFID information reading and recording device. When the material is put back into the production line, the information reading device 10 can determine that the material has been repaired based on the repair identifier and then transfer it to the corresponding processing section for processing. This improves the processing efficiency of the automated production line.
[0080] This invention also proposes a detection system based on the aforementioned material re-feeding control method, with reference to... Figure 4 The detection system includes:
[0081] The information reading device 10 is used to read information from the processed material and output corresponding identification signals;
[0082] The control device 20 is electrically connected to the information reading device 10 and is used to transfer the processed material to the corresponding processing section when the input processed material is determined to be a repaired processed material according to the identification signal, so that the processed material can be processed in the corresponding processing section.
[0083] The detection device 30 is electrically connected to the control device 20. The detection device 30 is used to detect the material being processed and output a corresponding detection signal to the control device 20.
[0084] Information writing device 40, which is electrically connected to the control device 20;
[0085] The control device 20 is used to control the information writing device 40 to write a corresponding identifier to the processed material when it is determined from the detection signal that there is a defect in the processed material.
[0086] The conveying mechanism 50 is used to convey the material to be processed in the horizontal direction, and multiple processing sections are formed in the length direction of the conveying mechanism 50.
[0087] The section module includes an information reading device 10, a detection device 30, and an information writing device 40.
[0088] The control module is used to control the conveying mechanism 50 to convey the material to be processed to the corresponding processing section according to the identification signal, so that the material to be processed can be processed in the corresponding processing section.
[0089] In this embodiment, the conveying mechanism 50 includes a conveyor belt, and different types of conveyor belts can be selected according to actual application requirements, characteristics of the processed materials, transmission speed, load capacity and other factors.
[0090] In accordance with the above embodiments, if the carrier containing the processed material has a QR code, barcode, or other identification code affixed to it, the detection device 30 detects the processed material according to the identification code and outputs a corresponding detection signal to the control device 20. When the control device 20 determines that the processed material has a defect based on the detection signal, the control information writing device 40 writes a corresponding identification code onto the processed material and discharges it through the outlet of the corresponding processing section to facilitate defective product repair. After repair, the repaired processed material can be re-input into the starting position re-input port 70 of the conveying mechanism 50. When the repaired processed material flows through different processing sections, the information reading device 10 of each processing section reads the identification code of the processed material and outputs a corresponding identification signal to the control device 20. The control device 20 controls the conveying mechanism 50 to convey the processed material to the corresponding processing section according to the identification information, so that the processed material can be processed in the corresponding processing section. It should be noted that the information reading device 10 can output an identification signal to the cloud server, and the detection device 30 can output a detection signal to the cloud server, so that the cloud server can process and analyze the corresponding signals and output corresponding control signals to the conveying mechanism 50 to convey the corresponding processed material to the processing section that needs to be processed.
[0091] It is understandable that the information reading device 10 and the information writing device 40 can be integrated into the same device. For example, this can be achieved through an RFID system reader. Each processing section is equipped with a reader and a detection device 30. On the production line, when a product passes through a processing section, the RFID reader installed in that section sends a command to the RFID tag on the product, writing the current processing section's identification information (such as A1, A2, etc.) and other relevant data into the chip within the electronic tag. This process requires no physical contact and can be completed within milliseconds. Similarly, a separate RFID information reading and recording device is used outside the production line. After a product is repaired, it is placed into the RFID information reading and recording device. The device automatically writes the information of the processing section requiring reprocessing based on the information read from the RFID chip on the product. Repair identification information is exemplified by B1, B2, B3… using the letter B to distinguish the normally circulating unit identifier A. When a product with an RFID tag passes through the detection device 30 of the processing section, the reader reads the repair identification from the tag. Based on the information read (such as distinguishing whether a product is a repeat product based on unit identifier A or B, and determining the processing section based on the number), the system automatically makes a decision and transmits the product to the processing section that needs processing via the conveyor mechanism 50. For example, when information starting with B is detected, it will be assumed to be a repeat product. Then, the system will judge the number after B. If the number is greater than the number in the current processing section, processing will begin in this section. If the number is less than the number in the current processing section, the product will flow into the next processing section without processing in this section.
[0092] The information reading device 10, information writing device 40, and detection device 30 enable the identification and classification of reprocessed materials, saving labor costs and improving the identification rate. This, in turn, improves the processing efficiency of the automated production line. Furthermore, RFID technology, through its wireless communication capabilities, enables unique identification and tracking of each product during automated production, not only enhancing the transparency and flexibility of the production process but also significantly improving the efficiency and accuracy of managing and handling defective products.
[0093] In another embodiment of the invention, reference Figure 4 The detection system also includes a defective product discharge port 60 and a re-entry port 70, wherein the defective product discharge port 60 is disposed on one side of the conveying mechanism 50;
[0094] The control device 20 is used to control the information writing device 40 to write a corresponding identifier to the processed material when it is determined from the detection signal that there is a defect in the processed material, and to transmit the processed material with the defect to the defective product discharge outlet 60.
[0095] The conveying mechanism 50 is configured to start from the refill port 70 at one end of itself, which is the starting end of the automated production line;
[0096] The information reading device 10 is used to read information about the processed material fed into the feed port 70 and output a corresponding identification signal to the control device 20.
[0097] The control device 20 is used to control the conveying mechanism 50 to convey the material to the corresponding processing section when the input material is determined to be a repaired material according to the identification signal, so that the material is processed in the corresponding processing section.
[0098] In this embodiment, the defective product outlet 60 can be located on one side of the conveyor belt. This allows the detection device 30 to detect the processed material and, upon determining a defect, the control information writing device 40 to write a corresponding identifier, which is then discharged through the defective product outlet 60 corresponding to the current processing section. After manual or mechanical repair, the material is fed into the re-feeding inlet 70. The conveying mechanism 50 feeds the re-feeded processed material into each processing section, allowing the information reading device 10 of each processing section to read its information and output an identifier signal to the control device 20. The control device 20 determines the processing section where the processed material needs to be processed based on the identifier signals output by the information reading device 10 of each processing section and controls the conveying mechanism 50 to transport it to the corresponding processing section for processing. It should be noted that each processing section can be equipped with at least one defective product outlet 60 to promptly discharge any processed material with defects, preventing defective products from flowing into the next processing section and reducing waste and loss in subsequent processes. At the same time, by promptly removing defective products, the downtime of the production line caused by handling defective products was reduced, ensuring the smoothness of the production process and thus improving overall production efficiency.
[0099] The defective product discharge port 60 ensures that defective products are immediately discharged from the current processing stage upon discovery, preventing them from flowing into the next processing step. This reduces further processing of defective products in subsequent processes and lowers material, labor, and time costs associated with rework or scrapping. The rework port 70 allows repaired materials to be re-inspected from the beginning, ensuring that defective products undergo inspection and processing at every step of the production process. This avoids potential product quality issues caused by rework in intermediate stages and prevents disruption to the normal production line. Thus, production quality and efficiency are improved.
