[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with a roller feeding module, which includes a feed port, a roller 1, a pressure sensor, an infrared sensor, a speed sensor, a servo motor, a roller, a torque sensor, a fixing plate and a dust removal brush. The roller 1 in the roller feeding module, the roller driven by the servo motor and the torque sensor can realize accurate control of the conveying process of the raw materials of automotive fasteners. The torque sensor can monitor the torque borne by the roller in the conveying process in real time, so as to adjust the output of the servo motor to ensure that the raw materials of automotive fasteners are fed into the stamping and forming area with a stable speed and force, thereby improving the precision and stability of stamping and forming. The pressure sensors embedded in the front wall and the rear wall of the feed port can detect the pressure when the raw materials of automotive fasteners enter, which is helpful to judge whether the feeding state of the raw materials of automotive fasteners is smooth and whether there is a risk of jamming or clogging. At the same time, the infrared sensor ensures that the feeding operation is performed only when the raw materials of automotive fasteners are actually present, thereby avoiding the situation of empty delivery or wrong delivery. The speed sensor can also detect the pressure of the raw materials of automotive fasteners when feeding them. The moving speed of the raw materials of automotive fasteners during the feeding process is monitored in real time. Combined with the control of the servo motor, the speed can be adjusted instantly to ensure that the raw materials of automotive fasteners enter the stamping and forming area at the optimal speed, further improving production efficiency and product quality. The setting of the dust removal brush effectively removes impurities on the surface of the raw materials of automotive fasteners. If these impurities enter the stamping and forming process, they will affect the quality and precision of the product. Therefore, the use of the dust removal brush improves the cleanliness of the raw materials of automotive fasteners and the quality of the final product. The high-precision automotive fastener stamping and forming device integrates a variety of sensors and automatic control components to realize the automation and intelligent monitoring of the stamping and forming process of automotive fasteners, which not only improves production efficiency, but also reduces manual intervention and reduces the risk of human error, making the production process more stable and reliable. Therefore, it can solve the problems of low accuracy of material transportation, inability to monitor the feeding status, inability to monitor and adjust the feeding speed, and the need to clean the surface of the raw materials of automotive fasteners.

[0016] 2. The present invention is equipped with a stamping fixing module, which includes a storage plate, a vibration sensor, a roller 2, a limit block, a pressure plate and a limit hole. The symmetrically arranged limit blocks ensure the precise positioning of the raw materials of the vehicle fasteners during the stamping process. The space between the limit blocks is just suitable for placing the raw materials, avoiding the displacement or tilting of the raw materials of the vehicle fasteners during the stamping process, thereby improving the precision and consistency of the stamping forming. The vibration sensor embedded in the top of the storage plate can monitor the vibration of the storage plate during the stamping process in real time. Vibration is a common phenomenon in the stamping forming process, but excessive vibration can cause the position of the raw materials of the vehicle fasteners to shift and the stamping quality to deteriorate. Through the monitoring of the vibration sensor, the stamping parameters can be timely discovered and adjusted or other shock-absorbing measures can be taken to reduce The influence of vibration on stamping quality is reduced. At the same time, the setting of roller one and roller two not only helps the smooth movement of the raw materials of automotive fasteners during the feeding process, but also provides a stable support platform for the raw materials of automotive fasteners before stamping. The design of roller one reduces the friction between the raw materials of automotive fasteners and the storage plate, so that the raw materials of automotive fasteners can more easily reach the accurate position and remain stable during the stamping process. The cooperation of the limiting holes and the limiting blocks inside the pressing plate ensures that the pressing plate can accurately contact the raw materials during the stamping process, avoiding the position shift of the raw materials during the stamping process, thereby causing uneven stamping force. Therefore, the problems of inability to accurately position during the stamping process, inability to monitor and adjust the vibration condition and stability, and poor stability of the stamping process can be solved.

[0017] 3. The present invention is equipped with a stamping forming module, which includes an upper die, a cutting knife, a lower die, a left limit plate, a rear limit plate and a temperature sensor. The upper die and the lower die connected to the bottom of the lifting plate together constitute the key components of stamping forming. The cooperation between the upper die and the lower die can ensure that the automotive fasteners obtain extremely high dimensional accuracy and shape consistency during the stamping process. At the same time, a temperature sensor is embedded in the contact surface of the upper die and the lower die, allowing real-time monitoring of the temperature change of the die during the stamping process. The die temperature is one of the important factors affecting the quality of stamping forming. Too high or too low temperature may lead to uneven material deformation and increased die wear. Through the monitoring of the temperature sensor, the die temperature can be adjusted in time to ensure that the die temperature is always kept within the optimal range, thereby improving the accuracy and quality of stamping forming. Stability. The stamping module also includes a left limit plate and a rear limit plate. The left limit plate and the rear limit plate together with the lower die constitute a stable stamping environment. The function of the left limit plate and the rear limit plate is to further position and fix the raw materials of automotive fasteners during the stamping process to prevent them from moving or offsetting during the stamping process, thereby ensuring the accuracy and consistency of stamping. The cutting knife is located between the upper die and the pressing plate, allowing cutting operations to be performed immediately after the stamping is completed to separate the automotive fasteners from the raw materials. This instant cutting method reduces subsequent processing steps and waiting time, and improves production efficiency. Therefore, it can solve the problems of poor stamping accuracy and consistency, the inability to monitor and control the temperature of the stamping process, the loose positioning and fixation during the stamping process, and the inconvenient cutting and separation after stamping.

[0018] 4. The present invention is equipped with an electric push rod, a cross booster frame, a collection hole and a vehicle fastener collection box. The combination of the electric push rod and the cross booster frame realizes the automatic ejection and pushing function after stamping. After the stamping is completed, the electric push rod drives the cross booster frame to move, so that the formed vehicle fasteners can be pushed out of the lower die, thereby reducing the steps of manual material collection and improving the degree of production automation and efficiency. The displacement sensor installed inside the cross booster frame can monitor and measure its displacement in real time, ensuring the accuracy and repeatability of the push, which helps to maintain the consistency of the product and reduce the scrap rate. At the same time, the displacement sensor can also provide important fault diagnosis and maintenance for the equipment. Data support, and the collecting hole opened at the bottom of the stamping forming body is located on the front of the lower die, and the collecting hole is located above the automotive fastener collection box, so that the automotive fasteners that have completed stamping and finalization fall directly into the collecting hole, and fall into the automotive fastener collection box below by gravity, so that the automotive fasteners that fall from the collecting hole can be collected at any time. This effective separation and collection method of finished products reduces the workload of manual cleaning, improves the cleanliness and safety of the production site, makes the production process smoother, and reduces the time wasted waiting for collection or transfer of finished products. Therefore, it can solve the problems of manual collection of automotive fasteners, low collection efficiency and low degree of production automation. BRIEF DESCRIPTION OF THE DRAWINGS

The raw materials of automotive fasteners are stamped and formed on the surfaces of the stamping and fixing module and the stamping and forming module.

[0038] Furthermore, in S2, the following steps are also included: S21, after the infrared sensor detects the raw material of the vehicle fastener, the speed sensor starts to monitor the moving speed of the raw material of the vehicle fastener, and at the same time, the servo motor drives the roller 4 to rotate to assist in conveying the raw material of the vehicle fastener; S22, when the raw material of the vehicle fastener passes through the dust removal brush 5, the dust removal brush 5 removes impurities on the surface thereof.

[0039] Working principle: The raw materials of automotive fasteners are placed in the feed port 2, and the roller 3 assists the raw materials to enter the inside of the stamping body 1. At the same time, the pressure sensors on the front wall and the rear wall detect the pressure when the raw materials enter to ensure a smooth feeding process. The infrared sensor detects whether there are raw materials in the feed port 2. The speed sensor monitors the moving speed of the raw materials to ensure that the feeding speed is moderate. The servo motor drives the roller 4 to rotate, further assisting the raw materials to move inside the stamping body 1. The torque sensor on the roller 4 monitors the torque during the conveying process to ensure that the motor works normally. During the movement of the raw materials, the dust removal brush 5 removes impurities on its surface to ensure the quality of stamping. The raw material is placed on the storage plate 6, and the vibration sensor detects the vibration during the stamping process to ensure the stability of the stamping process. The roller 2 7 and the roller 1 3 work together to further assist the movement of the raw material during the stamping process. The two sets of limit blocks 8 fix the raw material at the stamping position to prevent it from shifting during the stamping process. The support slide bar 9 and the sliding sleeve provide a stable lifting track for the lifting plate 10. The hydraulic rod 11 drives the lifting plate 10 and the mounting plate 12, the pressing plate 13, the upper die 15 and the cutting knife 16 thereon to move up and down through telescopic movement to complete the punching and cutting actions; The upper die 15 and the lower die 17 are in contact with each other to stamp the raw materials. The temperature sensor on the contact surface of the two monitors the temperature during the stamping process to ensure that the mold temperature is appropriate to avoid overheating or overcooling that affects the molding quality. The left limit plate 18 and the rear limit plate 19 limit the horizontal movement of the raw materials during the stamping process to ensure the stamping accuracy. The electric push rod 20 drives the cross booster frame 21 to move precisely to assist the stamping process or demolding. The displacement sensor monitors the displacement of the cross booster frame 21 to ensure precise movement. The stamped fasteners fall into the automotive fastener collection box 22 through the collection hole 23.
