Background Art

[0002] In the connector stamping control technology of electronic equipment, it is necessary to control the intelligent material tray to continuously feed the metal strip to the feeding mechanism of the stamping machine. In order to achieve continuous feeding of the metal strip, it is currently mainly achieved through the cooperation of the intelligent material tray, the swing guide rod and the machine tool control host. The machine tool control host has a preset 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 connected to the swing guide rod. Through the swing guide of the swing guide rod, the released metal strip is delivered to the feeding mechanism of the stamping machine. Although the continuous feeding of the metal strip can be achieved by presetting the control cycle program, if a feeding failure occurs during the feeding process, it is easy to cause damage to the punch of the stamping machine. Moreover, if there is a deformation defect in the metal strip, the stamped connector will also have an increased defective rate. The defect screening of these defective products requires a lot of manpower, resulting in an increase in the manufacturing cost of the connector.

[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.

DETAILED DESCRIPTION

[0009] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0010] Embodiment 1 See also Figure 1-Figure 3 , an embodiment of the present invention provides an intelligent control system for connector stamping, comprising: An intelligent material tray, used for rotating and releasing a rolled metal strip, wherein the metal strip is used for stamping and forming a connector of an electronic device; A swing guide rod is located at the material strip output side of the smart material tray, connected to the metal material strip released by the smart material tray, and used to guide and convey the metal material strip released by the smart material tray to the feeding mechanism of the stamping machine. After the feeding mechanism obtains the metal material strip, it is transmitted to the stamping machine for stamping and forming; A pressure sensor is arranged in the swing track area of ​​the swing guide rod. 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 out. The machine tool control host is connected to the pressure sensor for communication, and is used to receive the guide rod contact signal, and after determining that the metal strip released by the smart tray has completed conveying according to the guide rod contact signal, sends a feeding control signal to the smart tray to continue rotating and release the metal strip; The material feeding detection visual component is connected and communicated with the machine tool control host, and is arranged at the material belt inlet end of the feeding mechanism. The deformation state of the metal material belt passing through the material belt inlet end is detected to obtain a material belt deformation state signal and send it to the machine tool control host. The machine tool control host controls the stamping action of the stamping machine according to the material belt deformation state signal.

[0011] 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 and triggers the smart material tray to continue rotating. A feeding control signal is sent 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. Each time before the released metal strip enters the feeding mechanism of the stamping machine, the feeding detection visual component arranged at the strip inlet end of the feeding mechanism will detect the deformation state of the metal strip passing through the strip inlet end, so as to obtain the strip deformation state signal and send it to the machine tool control host. The machine tool control host controls the stamping action of the stamping machine according to the strip deformation state signal, thereby realizing stamping control and avoiding punching empty punching or punch damage caused by abnormal feeding. In the prior art, the preset control cycle program cannot detect the deformation state of the strip in real time. If there are defects in the metal strip itself, these defects will be directly transmitted to the stamping forming stage, resulting in a decrease in the yield rate. In this embodiment, the visual component detects the deformation of the strip in real time when the strip enters the feeding mechanism (such as no deformation, bending, crease or crack), and generates a strip deformation state signal. The machine tool control host controls the stamping action or suspends the stamping action according to the strip deformation state signal to prevent defective strips from entering the stamping process. In this embodiment, through the real-time detection function of the visual component, the defective products caused by the material belt problem can be reduced and the yield rate can be improved. It can be understood that in the prior art, the preset control cycle program only relies on a fixed time interval to drive the material tray, and there is no feedback mechanism combined with the material belt state. Material belt defects or feeding abnormalities will be directly ignored, and defective products can only be sorted by manual screening, resulting in low manufacturing efficiency and high cost. It should be noted that in this embodiment, through the cooperation of the pressure sensor and the swing guide rod, the continuous feeding of the feeding mechanism can be achieved, and the feeding detection visual component can detect the deformation state of the metal material belt passing through the inlet end of the material belt to obtain the material belt deformation state signal and send it to the machine tool control host. The machine tool control host controls the stamping action of the stamping machine according to the material belt deformation state signal, thereby realizing the continuous feeding of the metal material belt and the stamping action control of the stamping machine, avoiding the punch damage caused by the abnormal feeding, and at the same time reducing the defective products caused by the material belt problem and improving the yield rate.

[0012] In some preferred embodiments, when the feed detection visual component does not detect that the material belt entrance end passes through the metal material belt, 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 belt 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 belt 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 belt enters the feeding mechanism, it immediately sends a waiting feed signal to the machine tool control host, suspends the action of the stamping machine, avoids empty punching problems caused by feeding interruptions or abnormalities, and ensures that the stamping action is only performed after the material belt is correctly fed, thereby protecting equipment, reducing maintenance costs, and improving the reliability of the production line.

[0013] In some preferred embodiments, when the feed detection visual component detects that the material belt inlet end passes through the metal material belt, the deformation state of the metal material belt passing through the material belt inlet end is detected to obtain a material belt deformation state signal and send it to the machine tool control host. It should be noted that the material belt 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 material belt defects can be discovered in advance through real-time detection of the deformation state of the material belt by the feed detection visual component, and a deformation state signal is generated and sent 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 belt defects, improving the yield rate, reducing material waste, and optimizing production costs.

[0014] 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. The creases of the strip usually have a greater impact on the stamping accuracy, which will cause the finished product size to be inconsistent or surface defects. The cracks in the strip have a serious impact on the integrity of the strip, which directly leads to stamping failure or equipment damage. If the strip is not deformed, it is a normal state and can be stamped normally.

[0015] 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, 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 invisible deformation of the material strip 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 qualified rate of stamped products, effectively reducing the defective rate caused by deformed material strips, and optimizing production efficiency.

[0016] In some preferred embodiments, when the machine tool control host controls the stamping action of the stamping machine according to the strip deformation state signal, it includes: analyzing the strip deformation state signal, if the deformation state of the metal strip is bent, it is determined that the metal strip has a deformation defect, and the stamping machine is controlled to stop the stamping action, and a strip bending defect prompt is sent to the on-site inspection terminal. It should be noted that the bent strip may cause positioning deviation of the strip in the stamping machine, resulting in deviation in the size or shape of the stamped product. In this embodiment, by timely identifying the bending defect and stopping the stamping, products that do not meet the quality standards are prevented from entering the subsequent process. In addition, the bent strip may cause the mold to be unable to accurately align the strip or apply uneven pressure to the strip during the stamping process, increasing the risk of damage to the punch. In this embodiment, by stopping the stamping action, the equipment can be protected and the service life of the punch of the stamping machine can be extended. In addition, in this embodiment, sending the strip bending defect prompt to the on-site inspection terminal helps the operator to quickly locate and handle the problem strip and reduce 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 feeding device, etc.), enhancing the efficiency of human-computer interaction and reducing the time for problem identification and processing.

[0017] 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, if the deformation state of the metal material strip is a material strip crease, it is determined that the metal material strip has a deformation defect, and the stamping machine tool is controlled to stop the stamping action, and a material strip crease defect prompt is sent to the on-site inspection terminal. It should be noted that the material strip crease will cause the surface of the stamped product to be uneven or deformed, and ultimately the finished product will not meet the design requirements. Moreover, the crease may change the stress distribution of the material strip, affecting the structural strength and precision after stamping. In this embodiment, by identifying and stopping the operation before the creased material 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 material strip crease can help the operator quickly locate the problem, and the operator can quickly intervene and deal with the problem material strip (such as replacing the material strip).

[0018] 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: parsing the material strip deformation state signal, if the deformation state of the metal material strip is a material strip crack, it is determined that the metal material strip has a deformation defect, and the stamping machine tool 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 material strip crack directly affects the integrity of the stamping forming, causing the product to break or fail to form, 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 material strip is a material strip crack obtained by parsing, it is determined that the metal material strip has a deformation defect, and the stamping machine tool is controlled to stop the stamping action, so that the cracked material strip can be prevented 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).

[0019] In some further 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: first analyzing whether the deformation state of the metal material strip is the material strip non-deformation state, and when the deformation state of the metal material strip is not the material strip non-deformation state, then analyzing whether the deformation state of the metal material strip is the material strip crack state, and when the deformation state of the metal material strip is not the material strip crack state, then analyzing whether the deformation state of the metal material strip is the material strip bending state or the material strip crease state; wherein, the material strip deformation state signal is an image signal. It should be noted that in most cases, the metal material strip is in a normal non-deformation state. Directly judging the non-deformation state can quickly confirm that the material strip is available without further analyzing other states. If the material strip is in a non-deformation state, the stamping action can be performed directly, omitting the analysis of cracks, bends and creases, thereby reducing unnecessary calculations and saving computing resources. Moreover, directly analyzing the non-deformation state can quickly pass the normal process and speed up the production rhythm. In addition, in the non-deformed state, prioritizing the analysis of whether it is a crack state can avoid the expansion of major problems. Among them, the crack is the most destructive problem in the deformation state to production, which directly leads to the unusability of the material strip. Prioritizing the detection of the crack state can quickly eliminate unqualified material strips. If there is a crack in the material strip, there is no need to continue to detect the bending or crease state, because the crack is enough to terminate the feeding and stamping process. Both the bent state material strip and the crease state material strip can be adjusted by the correction device. After confirming that the material strip has neither cracks nor deformation, the bending or crease state is analyzed, which helps to allocate computing resources to more critical detection tasks.

[0020] In some preferred embodiments, the intelligent material tray includes a reel, a servo motor assembly and a frequency conversion controller; the reel is connected to the servo motor assembly, the servo motor assembly is connected to the frequency conversion controller, the reel is used to reel and release the metal strip, the servo motor assembly is used to drive the reel to rotate, and the frequency conversion controller is used to receive the feeding control signal sent by the machine tool control host to control the servo motor assembly to drive the reel to continue to rotate and release the metal strip. It should be noted that stamping production has high requirements for the feeding accuracy of metal strips. If the feeding is uneven or the speed is unstable, the tension of the strip in the feeding mechanism will be inconsistent, which will affect the stamping accuracy. In this embodiment, the reel is driven by the servo motor assembly, and the speed of the servo motor is adjusted by the frequency conversion controller, so that the feeding speed and tension can be accurately controlled, the uniformity and stability of the metal strip feeding can be ensured, the accuracy of the stamping process can be improved, and the problems of strip offset and tension imbalance caused by too fast or too slow feeding can be avoided. 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 belt synchronously when the material belt is consumed, realize the seamless connection of feeding and stamping rhythm, and improve production efficiency.

[0021] In some further preferred embodiments, the feed detection visual component does not detect that the material belt inlet end passes through the metal material belt, and when the machine tool control host controls the stamping machine to wait for the feeding mechanism to supply the metal material belt, the machine tool control host obtains the working state of the pressure sensor, and determines whether the pressure sensor is faulty according to the working state of the pressure sensor. If the pressure sensor is faulty, the fault state 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 belt released by the smart tray has completed the conveying according to the guide rod contact signal, and cannot send a feeding control signal to the smart tray to continue rotating and releasing the metal material belt, causing the feeding to be interrupted. Therefore, the feed detection visual component cannot detect that the material belt inlet end passes through the metal material belt. 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 defect type prompting, which can reduce problem troubleshooting time, quickly locate the root cause of the problem, improve the system fault diagnosis capability, and improve the operating efficiency of the production line.

[0022] In some further preferred embodiments, the feed detection visual component does not detect that the material belt inlet passes through the metal material belt, and when the machine tool control host controls the stamping machine to wait for the feeding mechanism to supply the metal material belt, the machine tool control host obtains the working state of the frequency conversion controller, and determines whether the frequency conversion controller has a fault according to the working state of the frequency conversion controller. If the frequency conversion controller has a fault, the fault state of the frequency conversion controller is sent to the on-site inspection terminal for defect type prompt. It should be noted that the frequency conversion controller is responsible for adjusting the speed and direction of the servo motor driving the reel. If the frequency conversion controller fails, it will directly lead to the interruption of the material belt feeding. Therefore, the feed detection visual component cannot detect that the material belt inlet passes through the metal material belt. In this embodiment, the working state of the frequency conversion controller is obtained, and the working state of the frequency conversion controller is determined according to the working state of the frequency conversion controller. If the frequency conversion controller has a fault, the fault state of the frequency conversion controller is sent to the on-site inspection terminal for defect type prompt, which can reduce the time for troubleshooting, quickly locate the root cause of the problem, improve the system fault diagnosis capability, and improve the operation efficiency of the production line.

[0023] In some further preferred embodiments, the feed detection visual component does not detect that the material belt inlet end passes through the metal material belt, and when the machine tool control host controls the stamping machine to wait for the feeding mechanism to supply the metal material belt, the machine tool control host first obtains the working state of the pressure sensor to judge the fault state, and when it is determined that the pressure sensor does not have a fault, it obtains the working state of the frequency conversion controller to judge the fault state. 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 judge whether the material belt has completed the conveying. If the pressure sensor fails, the feeding process cannot be completed smoothly. The frequency conversion controller is responsible for driving the servo motor to control the material reel to release the material belt, but this process depends on the pressure sensor signal trigger. In this embodiment, by first obtaining the working state of the pressure sensor to judge the fault state, the invalid troubleshooting that may be caused by directly checking the frequency conversion controller can be avoided, thereby improving the efficiency of fault diagnosis.
