[0001] The present invention relates to the technical fields of Internet of Things control systems, forming machine tools, machine tool programmable control systems, connector manufacturing, and more particularly to an intelligent control system for connector stamping and a connector. Background Art

[0002] In the connector stamping control technology for electronic devices, it is necessary to control an intelligent material tray to continuously feed the metal strip to the feed mechanism of the stamping machine. To achieve this continuous feeding of the metal strip, the intelligent material tray, a swinging guide rod, and a machine control host are currently the primary means of cooperating. The machine control host has a pre-set feeding control cycle program. After each feeding cycle, the intelligent material tray is controlled to rotate once to release the metal strip. The released metal strip is then connected to the swinging guide rod, which then guides the released metal strip to the feed mechanism of the stamping machine. Although this pre-set control cycle program can achieve continuous feeding of the metal strip, feeding failures during the feeding process can easily damage the punch of the stamping machine. Furthermore, if the metal strip exhibits deformation defects, the stamped connector will also have an increased defective rate. Screening for these defects requires a significant amount of manpower, increasing connector manufacturing costs.

[0003] In summary, the existing connector stamping control technology for electronic equipment has technical problems such as the punch of the stamping machine tool is easily damaged, the defective rate of the stamped connector is increased, and the connector manufacturing cost is increased.

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1-Figure 3 , an embodiment of the present invention provides an intelligent control system for connector stamping, comprising:

[0021] An intelligent material tray, used to rotate and release the rolled metal strip, which is used to stamp out connectors for electronic devices;

[0022] a swing guide rod, located at the material strip output side of the smart tray, connected to the metal strip released by the smart tray, and used to guide and convey the metal strip released by the smart tray to the feeding mechanism of the stamping machine. The feeding mechanism obtains the metal strip and then transmits it to the stamping machine for stamping and forming;

[0023] a pressure sensor, arranged in the swing track area of ​​the swing guide rod, and when the swing guide rod swings to the position of the pressure sensor and contacts the pressure sensor, the pressure sensor senses the guide rod contact signal and sends it;

[0024] a machine tool control host connected to and communicating with the pressure sensor, configured to receive the guide rod contact signal, and after determining, based on the guide rod contact signal, that the metal strip released by the smart tray has completed conveying, send a feeding control signal to the smart tray to continue rotating and release the metal strip;

[0025] The material feeding detection visual component is connected and communicated with the machine tool control host, and is arranged at the material strip inlet end of the feeding mechanism. It detects the deformation state of the metal material strip passing through the material strip inlet end to obtain a material strip deformation state signal and sends it to the machine tool control host. The machine tool control host controls the stamping action of the stamping machine according to the material strip deformation state signal.

[0026] It should be noted that in the prior art, the preset control cycle program cannot detect whether the material belt has actually completed the conveying or whether it is stuck, and only mechanically drives the material tray to rotate according to the cycle instruction. This lack of status confirmation can easily lead to empty punching or misoperation, thereby damaging the punch. In this embodiment, the swing guide rod contacts the pressure sensor after completing the feeding action. The pressure sensor generates a guide rod contact signal and feeds it back to the machine tool control host. The machine tool control host determines that the feeding is completed based on the guide rod contact signal before triggering the smart material tray to continue rotating, and sends a feeding control signal to the smart material tray to continue rotating to release the metal material belt. The smart material tray continues to rotate to release the metal material belt. Before each released metal strip enters the stamping machine's feed mechanism, a feed detection vision component located at the strip inlet of the feed mechanism detects the deformation state of the metal strip passing through it. This generates a strip deformation status signal and transmits it to the machine control host. The machine control host then controls the stamping operation of the stamping machine based on this strip deformation status signal, thereby achieving stamping control and preventing blank punches or punch damage caused by feed anomalies. In the prior art, pre-set control cycle programs are unable to detect the strip deformation state in real time. If the metal strip itself has defects, these defects will be directly transmitted to the stamping stage, resulting in a decrease in yield. In this embodiment, the vision component detects the deformation state of the strip (such as lack of deformation, bends, creases, or tears) in real time as the strip enters the feed mechanism and generates a strip deformation status signal. The machine control host then controls or pauses the stamping operation based on the strip deformation status signal to prevent defective strips from entering the stamping process. In this embodiment, the real-time detection function of the visual component can reduce defective products caused by material strip problems and improve the yield rate. It is understandable that in the prior art, the preset control cycle program relies solely on fixed time intervals to drive the material tray, without a feedback mechanism that integrates the material strip status. Material strip defects or feeding anomalies are directly ignored, and defective products can only be manually screened and sorted, resulting in low manufacturing efficiency and high costs. It is important to note that in this embodiment, the combination of a pressure sensor and a swing guide rod can achieve continuous feeding of the feed mechanism. The feed detection visual component can detect the deformation state of the metal strip passing through the material strip inlet, generate a material strip deformation state signal, and transmit it to the machine tool control host. The machine tool control host controls the stamping action of the stamping machine based on the material strip deformation state signal, thereby achieving continuous feeding of the metal strip and controlling the stamping action of the stamping machine, avoiding empty punches or punch damage caused by feeding anomalies. At the same time, it helps to reduce defective products caused by material strip problems and improve the yield rate.

[0027] In some preferred embodiments, when the feed detection visual component does not detect that the material strip inlet end passes through the metal material strip, it sends a waiting feed signal to the machine tool control host, and the machine tool control host controls the stamping machine to wait for the feeding mechanism to supply the metal material strip according to the waiting feed signal. It should be noted that in the prior art, the preset control cycle program cannot monitor the feeding status in real time, and the stamping action will still be triggered when the material strip is stuck or the feeding is interrupted, resulting in empty punching of the stamping machine or even damage to the punch. In this embodiment, when the feed detection visual component does not detect that the material strip enters the feeding mechanism, it immediately sends a waiting feed signal to the machine tool control host, suspends the stamping machine action, avoids the problem of empty punching due to feeding interruption or abnormality, and ensures that the stamping action is only performed after the material strip is correctly fed, thereby protecting the equipment, reducing maintenance costs, and improving the reliability of the production line.

[0028] In some preferred embodiments, when the feed detection visual component detects that the material strip inlet end passes through the metal material strip, the deformation state of the metal material strip passing through the material strip inlet end is detected to obtain a material strip deformation state signal and send it to the machine tool control host. It should be noted that the material strip may have deformation defects such as bends, creases or cracks. If it enters the stamping machine directly without detection, these defects will lead to an increase in the defective rate of the stamped connector. In this embodiment, the real-time detection of the material strip deformation state by the feed detection visual component can detect material strip defects in advance, and generate a deformation state signal to send to the machine tool control host, so that it can dynamically adjust the stamping action (such as pausing stamping) according to the deformation state signal, thereby reducing defective products caused by material strip defects, improving the yield rate, reducing material waste, and optimizing production costs.

[0029] In some preferred embodiments, the deformation state of the metal strip includes no deformation of the strip, bending of the strip, creases of the strip or cracks in the strip. It should be noted that the deformation state of the metal strip is defined as no deformation of the strip, bending of the strip, creases of the strip or cracks in the strip, mainly to accurately identify different types of deformation during the detection process, so as to take targeted control and optimization of the stamping process. Among them, the bending of the strip may affect the conveying path of the strip in the feeding mechanism, but it can continue to be used through adjustment or correction. Strip creases usually have a greater impact on the stamping accuracy, which will cause the finished product size to be inconsistent or surface defects. Strip cracks have a serious impact on the integrity of the strip, which directly leads to stamping failure or equipment damage. No deformation of the strip is a normal state and can be stamped normally.

[0030] In some preferred embodiments, when the machine tool control host controls the stamping action of the stamping machine tool according to the material strip deformation state signal, it includes: analyzing the material strip deformation state signal, and if the analysis shows that the deformation state of the metal material strip is that the material strip is not deformed, controlling the stamping machine tool to perform the stamping action when the invisible deformed material strip is in place. It should be noted that the material strip is not deformed is a normal state for stamping. The stamping process has extremely high requirements on the positioning and shape of the material strip. Only when the material strip is not deformed and is completely in place can the accuracy of stamping be guaranteed. In this embodiment, the stamping machine tool is controlled to perform the stamping action when the invisible deformed material strip is in place only when the material strip is not deformed, ensuring that the stamping action is only performed when the material strip is in normal state, thereby improving the consistency and qualification rate of the stamped products, effectively reducing the defective rate caused by the deformed material strip, and optimizing production efficiency.

[0031] In some preferred embodiments, when the machine tool control host controls the stamping operation of the stamping machine based on the strip deformation status signal, the control includes: analyzing the strip deformation status signal; if the analysis indicates that the metal strip is bent, determining that the metal strip has a deformation defect, controlling the stamping machine to stop stamping, and transmitting a strip bending defect notification to the on-site inspection terminal. It should be noted that a bent strip may cause positioning deviation of the strip in the stamping machine, resulting in deviations in the size or shape of the stamped product. In this embodiment, by promptly identifying a bending defect and stopping stamping, products that do not meet quality standards are prevented from entering subsequent processes. Furthermore, a bent strip may cause the die to lose accurate alignment with the strip during stamping or apply uneven pressure to the strip, increasing the risk of damage to the punch. In this embodiment, stopping the stamping operation protects the equipment and extends the service life of the punch of the stamping machine. Furthermore, in this embodiment, transmitting a strip bending defect notification to the on-site inspection terminal helps operators quickly locate and address the problematic strip, reducing unnecessary production delays. The prompt of the strip bending defect allows the operator to quickly understand the specific defect status of the strip and take necessary measures (such as checking the source of the strip, adjusting the loading device, etc.), enhancing the efficiency of human-computer interaction and reducing the time for problem identification and processing.

[0032] In some preferred embodiments, when the machine tool control host controls the stamping action of the stamping machine based on the strip deformation state signal, the control includes: analyzing the strip deformation state signal; if the analysis shows that the deformation state of the metal strip is a strip crease, determining that the metal strip has a deformation defect, controlling the stamping machine to stop the stamping action, and sending a strip crease defect prompt to the on-site inspection terminal. It should be noted that strip creases can cause the surface of the stamped product to be uneven or deformed, ultimately causing the finished product to not meet the design requirements. Moreover, creases may change the stress distribution of the strip, affecting the structural strength and precision after stamping. In this embodiment, by identifying and stopping the operation before the creased strip enters the stamping machine, the production of defective products is avoided, ensuring that the stamped finished product meets the design requirements, and improving product quality. The specific defect prompt of the strip crease can help the operator quickly locate the problem, and the operator can quickly intervene and deal with the problematic strip (such as replacing the strip).

[0033] In some preferred embodiments, when the machine tool control host controls the stamping action of the stamping machine according to the material strip deformation state signal, it includes: parsing the material strip deformation state signal, and if the analysis shows that the deformation state of the metal strip is a strip crack, it is determined that the metal strip has a deformation defect, and the stamping machine is controlled to stop the stamping action, and a material strip crack defect prompt is sent to the on-site inspection terminal. It should be noted that the strip crack directly affects the integrity of the stamping process, causing the product to break or be unable to be formed, which does not meet the quality requirements at all. Even if the crack is stamped in some cases, the defect may still expand in subsequent processing, eventually causing the product to be scrapped. In this embodiment, when the deformation state of the metal strip is obtained as a strip crack by analysis, it is determined that the metal strip has a deformation defect, and the stamping machine is controlled to stop the stamping action, thereby avoiding the cracked strip from entering the stamping process, improving the yield rate and product consistency, and ensuring that the quality meets the standards. In addition, by sending crack defect prompts to the patrol terminal in real time, it helps operators quickly discover problems and intervene in time (such as replacing the material belt or checking the source of the material belt).

[0034] In some further embodiments, when the machine tool control host controls the stamping operation of the stamping machine based on the strip deformation state signal, the process includes: first analyzing whether the deformation state of the metal strip is in a non-deformed state; if not, then analyzing whether the deformation state is a crack; and if not, then analyzing whether the deformation state is a bend or a crease; wherein the strip deformation state signal is an image signal. It should be noted that in most cases, the metal strip is in a normal, non-deformed state. Directly determining the non-deformed state quickly confirms that the strip is usable without further analyzing other states. If the strip is in a non-deformed state, the stamping operation can proceed directly, omitting the analysis of cracks, bends, and creases, thereby reducing unnecessary calculations and conserving computing resources. Furthermore, directly analyzing the non-deformed state can expedite the normal process and accelerate production. In addition, in the non-deformable state, prioritizing the analysis of whether there is a crack state can prevent major problems from escalating. Among them, cracks are the most destructive problem in the deformation state to production, directly causing the material strip to be unusable. Prioritizing the detection of crack states can quickly eliminate unqualified material strips. If the material strip has a crack, there is no need to continue to detect the bending or crease state, because the crack is sufficient to terminate the feeding and stamping process. Both bent and creased material strips can be adjusted using a correction device. After confirming that the material strip has neither cracks nor deformation, analyzing the bending or crease state helps to allocate computing resources to more critical detection tasks.

[0035] In some preferred embodiments, the intelligent material tray includes a take-up and untake-down reel, a servo motor assembly, and a frequency converter. The take-up and untake-down reel is connected to the servo motor assembly, which is in turn connected to the frequency converter. The take-up and untake-down reel is used to take up and release the metal strip. The servo motor assembly is used to drive the take-up and untake-down reel to rotate. The frequency converter receives the feed control signal from the machine tool control host to control the servo motor assembly to drive the take-up and untake-down reel to continue rotating and releasing the metal strip. It should be noted that stamping production requires high feeding accuracy for metal strip. Uneven feeding or unstable speed can lead to inconsistent tension in the feed mechanism, further affecting stamping accuracy. In this embodiment, the servo motor assembly drives the take-up and untake-down reel, and the frequency converter adjusts the servo motor speed. This allows for precise control of feeding speed and tension, ensuring uniform and stable metal strip feeding, improving the accuracy of the stamping process, and avoiding problems such as strip deviation and tension imbalance caused by excessively fast or slow feeding. The frequency conversion controller is connected to the machine tool control host and can receive the feeding control signal in real time. It dynamically adjusts the operating status of the servo motor according to the control signal to ensure that the intelligent material tray releases the material strip synchronously when the material strip is consumed, realize the seamless connection between feeding and stamping rhythm, and improve production efficiency.

[0036] In some further preferred embodiments, the feed detection visual component does not detect that the material strip inlet end passes through the metal material strip. When the machine tool control host controls the stamping machine to wait for the feeding mechanism to supply the metal material strip, the machine tool control host obtains the working status of the pressure sensor, and determines whether the pressure sensor is faulty based on the working status of the pressure sensor. If the pressure sensor is faulty, the fault status of the pressure sensor is sent to the on-site inspection terminal for a defect type prompt. It should be noted that when the pressure sensor is faulty, the guide rod contact signal cannot be sensed, and the machine tool control host cannot determine that the metal material strip released by the smart tray has completed transportation based on the guide rod contact signal, and cannot send a feeding control signal to the smart tray to continue rotating and releasing the metal material strip, causing the feeding to be interrupted. Therefore, the feed detection visual component cannot detect that the material strip inlet end passes through the metal material strip. In this embodiment, the working status of the pressure sensor is obtained, and whether the pressure sensor is faulty is determined based on the working status of the pressure sensor. If the pressure sensor is faulty, the fault status of the pressure sensor is sent to the on-site inspection terminal for a defect type prompt. This can reduce the time for troubleshooting, quickly locate the root cause of the problem, improve the system fault diagnosis capability, and enhance the operating efficiency of the production line.

[0037] In some further preferred embodiments, if the feed detection visual component fails to detect the metal strip passing through the material inlet, and the machine tool control host controls the stamping machine to wait for the metal strip to be fed by the feed mechanism, the machine tool control host obtains the operating status of the frequency converter controller and determines whether the frequency converter controller is faulty based on the operating status. If the frequency converter controller is faulty, the fault status is transmitted to the on-site inspection terminal to indicate the defect type. It should be noted that the frequency converter controller is responsible for regulating the speed and direction of the servo motor driving the reel. A fault in the frequency converter controller directly interrupts the material feed, thus preventing the feed detection visual component from detecting the metal strip passing through the material inlet. In this embodiment, obtaining the operating status of the frequency converter controller and determining whether the frequency converter controller is faulty based on the operating status of the frequency converter controller and, if so, transmitting the fault status to the on-site inspection terminal to indicate the defect type can reduce troubleshooting time, quickly locate the root cause of the problem, improve the system's fault diagnosis capabilities, and enhance production line operational efficiency.

[0038] In some further preferred embodiments, when the feed detection visual component fails to detect the metal strip passing through the material strip inlet, and the machine tool control host controls the stamping machine to wait for the feed mechanism to supply the metal strip, the machine tool control host first obtains the operating status of the pressure sensor to determine the fault status. If it determines that the pressure sensor is not faulty, it then obtains the operating status of the frequency converter controller to determine the fault status. It should be noted that the pressure sensor is responsible for monitoring whether the swing guide rod is in place, and its signal is the direct basis for the machine tool control host to determine whether the material strip has been transported. If the pressure sensor fails, the feeding process cannot be completed smoothly. The frequency converter controller is responsible for driving the servo motor to control the material reel to release the material strip, but this process is triggered by the pressure sensor signal. In this embodiment, by first obtaining the operating status of the pressure sensor to determine the fault status, the invalid troubleshooting that may be caused by directly checking the frequency converter controller can be avoided, thereby improving the efficiency of fault diagnosis.
