Description

Technical Field

[0001] The invention belongs to the technical field of coolant purification, and in particular relates to a production process for an inner protective cover of a safety airbag tube. Background Art

[0002] In the existing production process of the protective cover inside the explosive tube of the airbag, the stamped parts have grease and other stains on their surface, so they need to be cleaned with hydrocarbons as required. After the hydrocarbon cleaning process, hydrocarbon cleaning liquid will remain on the surface of the parts, causing the parts to emit a similar odor. The odor still exists after loading, affecting the experience of people in the car; the stamped parts occasionally have defects such as burrs on the inside of the parts, and these defects cannot be solved in the production process. Before packaging and delivery, the burrs need to be manually identified with the naked eye, and the defective parts need to be inspected and sorted, resulting in extremely low production efficiency, visual fatigue of personnel, and missed detections and false detections.

[0003] Chinese patent CN114523700A discloses a hot pressing forming process for airbags, comprising the following steps: step S101, folding the airbag and wrapping it with a wrapping cloth; step S102, extruding the wrapped airbag; step S103, after hot pressing the airbag, cold pressing the airbag. The processing time of the airbag is shortened, and the production of the airbag is accelerated. The above process cannot effectively remove the burrs generated in the production of parts, resulting in cost loss, and cannot effectively remove the odor generated during the production of parts. Summary of the invention

[0004] The present invention aims to solve the problem that the microfiltration filter in the prior art cannot effectively filter impurities, while the nanofiltration membrane can effectively filter impurities, but at the same time it will remove the effective components in the coolant, resulting in coolant loss.

[0005] The technical solutions adopted in the present invention are:

[0006] A production process for an inner protective cover of a safety airbag tube comprises the following steps: P1: using a punch press to perform stamping processing on parts for producing the safety airbag;

[0007] P2: Use automatic hydrocarbon cleaning to clean the finished parts;

[0008] P3: Continuously dry the cleaned parts;

[0009] P4: Use the automatic detection equipment to take images of the parts after drying, and use the built-in image detection module of the automatic detection equipment to detect whether there are burrs on the parts;

[0010] P5: sort the parts that pass the inspection and finally pack them for storage.

[0011] By adopting the above technical solution, a punch press is used for precise stamping processing to ensure the consistency and precision of each part, thereby improving the quality of the final product. The automatic hydrocarbon cleaning technology can effectively remove dirt and grease on the surface of parts, ensure the cleanliness of parts, and avoid the impact of impurities on product performance. Through continuous drying operations, a seamless connection from cleaning to drying is achieved, which improves production efficiency and reduces waiting time. The use of automatic image detection equipment to quickly and accurately detect burrs on parts not only improves the detection speed, but also reduces human errors and ensures the accuracy of the detection results. In each step, parameters such as feeding step distance, cleaning temperature and time, and drying temperature are precisely controlled, which helps to save energy and reduce production costs. The automated sorting system can separate qualified products from unqualified products according to the set standards, and directly package and store them, reducing manual operations and improving work efficiency.

[0012] Further, in step P1, first, a coil flattening system is used to flatten the coil with a thickness of 1.0 mm, so as to ensure that the stamping raw material entering the continuous die system reaches a flatness of 0.1 mm within an area of ​​80 square millimeters;

[0013] Next, the leveled raw materials are fed into the automatic feeding system to facilitate the continuous automatic feeding of the raw materials, ensuring that the feeding step distance is 41mm-42mm each time;

[0014] The raw materials automatically enter the feeding system through the coil leveling system and then enter the special continuous die system for stamping into a specific shape that meets the requirements of the drawing;

[0015] Finally, the stamped parts are loaded into special cleaning baskets at 4,000 pieces per basket.

[0016] By adopting the above technical solution, the raw materials are pre-processed using a coil leveling system to ensure that the flatness of the materials entering the stamping stage reaches the standard of 0.1 mm. This helps to avoid product defects such as cracks and wrinkles caused by uneven material surfaces, thereby improving the quality of the final product. The automatic feeding system accurately controls the feeding step distance between 41mm and 42mm each time, ensuring that the continuous die system can operate stably and reducing the scrap rate caused by inaccurate feeding. From coil leveling to feeding to stamping, the entire process is highly automated, which not only improves production efficiency, but also reduces labor costs and the possibility of human errors. The use of a special continuous die system for stamping can ensure that each part strictly meets the requirements of the design drawings, achieving consistency and reliability under large-scale production conditions. By leveling the coil and accurately controlling the feeding step distance, the raw materials are used more effectively, reducing waste and saving costs. The 4,000 pieces per basket are loaded into a special cleaning basket to facilitate the processing and transportation of subsequent processes, improving the smoothness of the overall operation process.

[0017] Further, in step P2, first, the cleaning basket is placed at the loading position of the cleaning machine, the cleaning basket with the parts already loaded is placed at the loading port of the cleaning machine, and the cleaning basket is lifted to the main cleaning tank by the automatic program control robot arm of the cleaning machine;

[0018] The cleaning machine automatically closes the pre-immersion tank of the cleaning machine, starts the ultrasonic wave, starts the swing device, drives the special cleaning basket to swing, and the parts are ultrasonically immersed in the hydrocarbon cleaning liquid at a temperature of 30 degrees Celsius for 20 minutes, so that the hydrocarbon cleaning agent dissolves the dirt and grease on the surface of the parts. After the set time, the cylinder drive opens the lid and the robot arm lifts the washing basket;

[0019] The cleaning machine program controls the mechanical arm to lift the cleaning basket into the ultrasonic fine immersion tank, the ultrasonic wave is started, the swing device is started, and the special cleaning basket is driven to swing. The parts are ultrasonically immersed in the hydrocarbon cleaning liquid at a temperature of 30 degrees Celsius for 20 minutes again, so that the hydrocarbon cleaning agent can fully separate the dirt and grease on the surface of the parts from the parts. After the set time, the cylinder drive opens the lid and the mechanical arm lifts out the washing basket;

[0020] The cleaning machine program controls the mechanical arm to lift the cleaning basket into the drying tank, the tank door automatically closes, the drying system automatically starts, and the temperature in the tank is automatically maintained at the set 95℃-105℃ for 20 minutes, so that the residual cleaning liquid on the surface of the parts evaporates and is separated from the parts as much as possible;

[0021] The cleaning machine program controls the robotic arm to lift the cleaning basket to the discharge port, and the cleaning basket is automatically discharged out of the cleaning machine.

[0022] By adopting the above technical solution, two ultrasonic immersions (20 minutes each) are performed to ensure that the dirt and grease on the surface of the parts can be completely removed. This double treatment method greatly improves the cleaning effect, especially for contaminants in complex shapes or tiny gaps. A hydrocarbon cleaning fluid at a specific temperature (30 degrees Celsius) is used. The cleaning fluid has good solubility in grease and can effectively remove various types of oil stains and dirt. From the automatic lifting of the cleaning basket to the transfer between each tank, the entire process is highly automated, reducing the need for manual intervention and improving overall work efficiency. The time, temperature and other parameters of each stage are precisely controlled by the program to ensure that each batch of parts can be cleaned with consistent high quality. The closed cleaning machine design reduces the possibility of chemical substances volatilizing into the air, which not only protects the safety of operators, but also reduces the impact on the environment. In the final step of drying, by maintaining a constant temperature of 95°C to 105°C, the residual cleaning fluid on the surface of the parts is effectively evaporated, reducing the risk of contamination in subsequent processes and helping to maintain a clean working environment.

[0023] Further, in step S3, the cleaning basket is placed in the loading area of ​​the drying vehicle. Through the set program, the crawler of the drying equipment automatically rotates to send the cleaning basket into the drying oven. The drying equipment adopts a continuous drying operation, which is mainly composed of a drying chamber, a drying vehicle, a material tray, an air supply system, a hot air furnace, an automatic electronic control system, etc.

[0024] The crawler belt of the drying equipment rotates automatically, driving the cleaning basket into the oven. The effective baking length of the oven is 20 meters. The crawler belt is set to rotate automatically at a speed of 0.2 meters per minute. The temperature in the oven is automatically maintained at 178℃-182℃ through the temperature sensor.

[0025] The cleaning liquid remaining on the surface of the parts after cleaning is baked to evaporate it completely.

[0026] By adopting the above technical solution, by accurately controlling the temperature and crawler speed in the drying oven, it can be ensured that any residual cleaning liquid on the surface of the parts can be fully evaporated, avoiding corrosion or other quality problems caused by residual liquid. The automatic control system under the continuous drying operation mode can ensure that each batch of parts undergoes the same drying conditions, thereby ensuring the consistency and high quality of the products. The use of continuous drying equipment can process a large number of parts without interruption, greatly improving the overall efficiency of the production line. The entire process from the loading area to the inside of the drying oven is automatically controlled by the program, reducing the need for manual intervention and improving work efficiency. By accurately adjusting the temperature and crawler speed, the best drying effect is ensured at the lowest energy consumption, achieving the purpose of energy conservation and emission reduction. Due to the effectiveness of the drying process, the risk of defective or waste products caused by residual cleaning liquid is reduced, which helps to save material costs.

[0027] Further, in step S4, the baked parts are introduced into the loading hopper of the automatic image detection equipment, and the parts are arranged regularly according to the set track through the vibration plate;

[0028] The arranged parts enter the glass plate of the automatic image detection equipment, which rotates at 30 revolutions per minute. When the parts are transferred to the camera of the automatic image detection equipment, the camera takes a picture of the parts at a speed of 0.5 milliseconds and the computer system conducts a rapid AI comparison analysis with the set theoretical photos to determine whether the burrs and other dimensions of the inspected parts are qualified;

[0029] The judged parts are automatically sorted by the automatic image detection equipment. The qualified parts are blown into the hopper marked as qualified by the air nozzle, and the unqualified parts are blown into the hopper marked as unqualified by the air nozzle.

[0030] By adopting the above technical solution, the speed of 30 revolutions per minute ensures that the parts can be inspected quickly and orderly, greatly improving the inspection efficiency. The air nozzle is used to automatically blow qualified and unqualified parts into the corresponding hopper according to the judgment results of the computer system, without manual intervention, which greatly improves the work efficiency. The whole process from parts arrangement to final classification is almost completely automated, reducing the need for direct operation by workers and reducing the risk of injury caused by manual handling of sharp or high-temperature parts. The automated equipment can maintain a stable working state for a long time without being affected by factors such as fatigue, further ensuring the safety of the operation. Through precise detection, parts with quality problems can be discovered and removed in time, avoiding these problem parts from flowing into the next process, thereby reducing the cost and scrap rate of subsequent processing. Each inspection follows the same procedures and standards to ensure that all parts are inspected under the same conditions, thereby ensuring the consistency and quality stability of the product. If the system detects a large number of unqualified parts, it can immediately feedback to the previous process, facilitating timely adjustment of production process parameters to prevent the problem from expanding. Modern image automatic inspection equipment is usually equipped with data recording functions, which can record the inspection results of each part in detail. These data can be used to analyze potential problems in the production process and support continuous improvement.

[0031] Furthermore, in step S5, the parts that have passed the inspection are packaged and put into storage according to the packaging requirements.

[0032] The present invention has the following beneficial effects:

[0033] 1. The present invention realizes high automation and precise control in each step from coil leveling, stamping processing to cleaning, drying and testing. By using a special continuous die system for stamping processing, it is ensured that each part strictly meets the requirements of the design drawings. The automatic image detection equipment is used to quickly and accurately detect burrs and other dimensions of the parts, ensuring the high quality and consistency of the products. The automatic sorting system can separate qualified products from unqualified products according to the set standards, reducing the errors caused by manual operation and improving the consistency and reliability of the products.

[0034] 2. The present invention adopts a continuous drying operation mode, which realizes seamless connection from cleaning to drying, greatly improving production efficiency. Since the whole process is highly automated, it reduces labor costs and waiting time, and reduces overall production costs. By accurately adjusting parameters such as temperature and crawler speed, it achieves energy conservation and emission reduction while ensuring the best drying effect, which helps save energy and reduce costs;

[0035] 3. The automated equipment of the present invention maintains a stable working state for a long time, is not affected by factors such as fatigue, and reduces the need for direct operation by workers, reducing the risk of injury that may be caused by manual handling of sharp or high-temperature parts. The closed cleaning machine design reduces the possibility of chemicals volatilizing into the air, which not only protects the safety of operators but also reduces the impact on the environment. It supports continuous improvement through effective data recording and analysis functions, and promotes the sustainable development of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0042] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second" and the like do not indicate the importance of the components, and therefore cannot be understood as limiting the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0043] This embodiment provides a production process for an airbag tube inner protective cover, which can effectively detect burrs in the parts processing process and remove the odor of the processed products.

[0044] like Figure 1 As shown, the production process of the airbag tube inner protective cover includes the following steps: P1: using a punch press to punch the parts for airbag production;

[0045] P2: Use automatic hydrocarbon cleaning to clean the finished parts;

[0046] P3: Continuously dry the cleaned parts;

[0047] P4: Use the automatic detection equipment to take images of the parts after drying, and use the built-in image detection module of the automatic detection equipment to detect whether there are burrs on the parts;

[0048] P5: sort the parts that pass the inspection and finally pack them for storage.

[0049] like Figure 2 As shown, first, select a metal coil with a thickness of 1.0 mm and customize the width according to product requirements. Before entering the leveling machine, the coil surface is unfolded and cleaned by the uncoiler to remove oil and oxide layers to ensure the cleanliness of the material. A multi-roller leveling machine is used for leveling. The equipment includes straightening rollers (usually 9-13 groups) arranged in an upper and lower staggered manner. High-precision flatness control is achieved by adjusting the gap and pressure of the straightening rollers, so that the flatness error of the material within 80 square millimeters does not exceed 0.1 mm. The leveling speed is set to 8 meters / minute, and a laser thickness gauge is used to monitor the surface flatness of the material in real time. When local bumps are detected, the system automatically adjusts the roller pressure to compensate;

[0050] The leveled material enters the servo feeding system and seamlessly connects with the leveling system to achieve continuous feeding. The servo feeder accurately controls the feeding step distance through the encoder with an accuracy of ±0.05mm. The feeding step distance is set between 41mm and 42mm, and is dynamically adjusted by the PLC program according to the mold station requirements. The closed-loop feedback system is used to correct the step distance error to ensure the consistency of each feeding position, thereby increasing the stamping efficiency to 60-80 times / minute;

[0051] The raw materials, after being leveled and accurately fed, enter a special continuous die system for stamping processing. The continuous die system contains multiple stations, such as punching, forming, trimming, etc. The stations are arranged in sequence, and the materials are processed step by step. The mold material is SKD11 cemented carbide, with a heat treatment hardness of HRC58-62, and the surface is titanium-plated to extend the service life. The punching station uses a 200-ton hydraulic punch press, and the punching gap is set to 8%-12% of the material thickness to ensure that the cut is smooth and burr-free. Through progressive bending and stretching, the material is processed into a complex curved surface structure of the airbag protective cover that meets the requirements of the drawing. The integrated online visual system monitors the size of the stamping parts in real time, and immediately stops and alarms if the error exceeds the limit;

[0052] Finally, the stamped parts are sorted by the vibration plate according to the standard of 4,000 pieces per basket, and then stacked in layers by the robot arm into the 304 stainless steel cleaning basket. Each basket is designed with a layered structure (500 pieces per layer) to avoid the parts from being stacked and squeezed and deformed. The loading speed reaches 2-3 baskets per minute, which realizes standardized loading and reduces manual intervention, reduces the risk of scratches on the surface of parts, and improves the uniformity of subsequent cleaning and drying processes.

[0053] like Figure 3 As shown, first, prepare a special cleaning basket at the loading position of the cleaning machine, and place the cleaning basket containing 4,000 stamped parts at the loading port of the cleaning machine. The cleaning machine's automatic program controls the robotic arm to accurately lift the cleaning basket from the loading port to above the main cleaning tank; then, the robotic arm lowers the cleaning basket into the pre-immersion tank and starts the pre-immersion program. At this time, the pre-immersion tank is closed and starts working, and the ultrasonic device and the swing device are started synchronously. The parts are ultrasonically immersed in a hydrocarbon cleaning fluid maintained at a temperature of 30 degrees Celsius for 20 minutes to dissolve dirt and grease on the surface of the parts. After the set time is completed, the cylinder drives the lid to open, and the robotic arm lifts out the cleaning basket;

[0054] Then, according to the cleaning machine program instructions, the robot arm moves again and moves the cleaning basket to the ultrasonic fine immersion tank. During this process, the ultrasonic and swing functions are also activated to make the parts undergo a second 20-minute ultrasonic immersion under the same conditions (30 degrees Celsius hydrocarbon cleaning fluid). This step is designed to further remove any remaining dirt and grease to ensure that the surface of the parts is clean. After completion, the cylinder opens the lid again and the robot arm lifts the cleaning basket;

[0055] Then, the robot arm moves the cleaning basket to the drying tank according to the program settings. When the cleaning basket enters the drying tank, the tank door automatically closes and the drying system starts. The temperature inside the drying tank is precisely controlled between 95℃ and 105℃ and maintained for 20 minutes to evaporate the cleaning liquid remaining on the surface of the parts and minimize the impact of the liquid residue on the parts;

[0056] Finally, after the drying process is completed, the cleaning machine program instructs the robot arm to transfer the cleaning basket to the discharge port. Here, the cleaning basket is automatically pushed out of the cleaning machine and waits for the next operation or directly enters the packaging process.

[0057] like Figure 4 As shown, first, prepare the cleaning basket containing the cleaned parts in the loading area of ​​the drying equipment and place it securely in the area. This step uses the positioning device on the drying car to ensure that the cleaning basket is accurately placed in the predetermined position;

[0058] Then, the drying equipment is started according to the preset program, and its crawler automatically starts to rotate, steadily and continuously transporting the cleaning basket from the loading area to the inside of the oven. The whole process does not require manual intervention and realizes automatic operation;

[0059] The drying equipment used in the present invention is designed as a continuous operation mode, with multiple key components: drying chamber, drying vehicle, material tray, air supply system, hot air furnace and automatic electronic control system. Among them, the effective baking length of the oven is set to 20 meters, and the automatic rotation speed of the crawler is adjusted to 0.2 meters per minute to ensure that the parts in each washing basket can be fully and evenly heated. In addition, the temperature in the oven is accurately controlled and maintained between 178°C and 182°C by the temperature sensor to ensure the best drying effect;

[0060] As the cleaning basket gradually enters the oven, the high temperature environment in the oven causes the cleaning liquid remaining on the surface of the parts to evaporate quickly. This efficient drying mechanism not only completely removes the cleaning liquid, but also avoids any residual problems caused by uneven temperature or insufficient time, thus ensuring that the surface of the parts is clean and flawless;

[0061] After about 100 minutes of baking (calculated based on the above parameters), the cleaning basket moves with the track to the other end of the drying equipment, the discharge area. At this time, the cleaning liquid on the surface of the parts has completely evaporated and can be directly carried out to the next step or packaging process.

[0062] like Figure 5 As shown, the parts that have completed the drying process are introduced into the hopper of the automatic image inspection equipment. The equipment uses vibration plate technology to guide the parts to be neatly arranged according to a predetermined pattern through a set track. The design of the vibration plate is to ensure that the parts can enter the next inspection link in the best state and reduce the inspection error caused by improper position;

[0063] The arranged parts are then transported to the glass plate, the core component of the automatic image inspection equipment. The glass plate is set to rotate 30 times per minute to ensure that the parts can be fully inspected in a short time. This speed design can ensure sufficient inspection time while maintaining high production efficiency;

[0064] When the part rotates to a specific position with the glass plate, the high-speed camera installed there takes a picture of the part at an exposure speed of 0.5 milliseconds. The captured image is immediately received by the computer system, and the advanced AI algorithm is used to quickly compare and analyze it with the pre-stored theoretical standard photos. This process is mainly used to check whether the part has burrs and whether other dimensions meet the specification requirements. Through this high-precision image analysis technology, accurate judgment of part quality can be achieved;

[0065] Based on the results of image analysis, the automatic image inspection equipment will automatically classify the parts. Qualified parts will be blown into the hopper marked as "qualified" by the configured air nozzle; unqualified parts will be blown into the hopper marked as "unqualified". This not only improves the screening efficiency, but also effectively avoids the risk of misjudgment caused by manual sorting.

[0066] Working principle: First, in the material preparation stage, metal coils of specific thickness are selected, unrolled by an unwinder and flattened with a multi-roller flattening machine. Then, the servo feeding system and laser thickness gauge are used to monitor and adjust the flatness in real time to ensure the accuracy of the material. Next, in the stamping process, the flattened material enters the continuous die system for stamping processing including punching, forming, trimming and other steps. SKD11 carbide dies are used and titanium-plated on the surface to extend the service life and ensure smooth incisions without burrs. In the automatic cleaning stage, the stamped parts are placed in a special basket and cleaned by ultrasonic technology. The process is to immerse the parts in a 30-degree Celsius hydrocarbon cleaning solution for two 20-minute soaks each to effectively remove dirt and grease. The subsequent high-temperature drying process uses a drying device in a continuous operation mode to maintain the temperature in the furnace between 178°C and 182°C to ensure that each part is fully dried and avoid liquid residue. Finally, in the automatic image detection and sorting stage, the dried parts are neatly arranged on a vibrating plate and then enter the automatic image detection equipment. A high-speed camera takes photos and uses an AI algorithm to analyze whether there are burrs and other dimensions are qualified. The parts are automatically classified as "qualified" or "unqualified" based on the analysis results to achieve efficient screening. The entire process not only solves the burr problem in part processing, but also completely removes odors, provides high-quality airbag tube inner protective cover products, and greatly improves production efficiency and accuracy.

[0067] The preferred embodiments of the present invention are described in detail above; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
