Description

Technical Field

[0001] The present invention relates to the technical field of intelligent models of condom dry electrical inspection machines, and particularly to an on-line detection system and method for the capacitance of an intelligent model of a condom electrical inspection machine. Background Art

[0002] Condoms are family planning products in China, and the detection of pinholes in condom products is a major item in condom quality inspection. The quality of pinhole detection is directly related to the quality of the product. At present, there are two methods for pinhole detection in domestic condom production enterprises: wet electrical inspection and dry electrical inspection. When using the wet electrical inspection method, the following defects exist: 1. The product misdetection rate is relatively high; 2. Steam drying and compressed air separation of products are required, resulting in a certain amount of energy consumption; 3. The operating model temperature reaches about 50 degrees, which is not conducive to the operation of the staff. The detection principle of dry electrical inspection is to use conductive rubber to conduct electricity to scan the condom, install a storage capacitor in the model, and detect the stored charge to achieve the purpose of detecting the pinholes of the condom product. It has the advantages of low energy consumption and zero emissions, and at the same time improves the operation environment of the staff.

[0003] Since the capacitor works under the state of long-term high-voltage charging and short-circuit discharging, its capacitance is very easy to decay. Therefore, it is necessary to regularly detect the capacitor in the model. The detection principle is to detect each intelligent model. Each model has a capacitor. When the model passes through the high-voltage conductive rubber area, its high voltage charges each intelligent model through the conductive rubber, and then the charging power of each intelligent model is detected in the detection area. It is necessary to use a multimeter to measure more than 200 capacitors on the machine one by one, which is extremely inconvenient, time-consuming and laborious.

[0004] Therefore, it is necessary to provide an on-line detection system that can automatically detect the capacitance value and can directly perform maintenance in a timely manner based on the detection results to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an on-line detection system for the capacitance of an intelligent model of a condom electrical inspection machine. It solves the problem in the prior art that it takes a long time and is difficult to measure the capacitors in the model one by one with a multimeter, resulting in a decrease in production efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] Such as Figure 1 And 2As shown in the figure, an on-line detection system for the capacitance of an intelligent model of a condom electrical inspection machine includes a capacitor charge and discharge circuit 1, a PLC combined measurement circuit 2, and a display device 3. The capacitor charge and discharge circuit 1 is used to be electrically connected to the capacitor in the intelligent model of the condom electrical inspection machine. The capacitor is used to measure the stored electric charge after the condom pinhole detection to determine whether the condom is qualified. The PLC combined measurement circuit 2 includes a communication module 21, a control module 22, a data interface 23, and a storage module 24. The communication module 21 is electrically connected to the control module 22. The other end of the control module 22 is electrically connected to the data interface 23. The other end of the communication module 21 is electrically connected to the capacitor charge and discharge circuit 1. The other end of the data interface 23 is electrically connected to the display device 3. The storage module 24 is electrically connected to the data interface 23. A detection instruction is sent to the PLC combined measurement circuit through the display device. The PLC combined measurement circuit receives the detection instruction through the data interface and transmits it to the control module. The control module controls the communication module to send this detection instruction to the capacitor charge and discharge circuit. After receiving the detection instruction, the capacitor charge and discharge circuit uses a 12V adjustable regulated power supply to charge the capacitor with a capacitance of 1uF / 1600V in the intelligent model of the condom electrical inspection machine through a charging pile, and then discharges the capacitor, and transmits the effective signal of the discharge to the communication module. The communication module inputs it to the control module. The control module and the storage module process and save the effective signal respectively. The result is saved and re-recorded during the next test. The capacitor detection value obtained through the processing of the control module is sent to the display device, and the capacitance of each model is displayed through the display device. The adjustable power supply in the capacitor charge and discharge circuit is used in combination with the capacitor charging and discharging circuit. Through the PLC combined measurement circuit, the capacitor can be automatically detected, improving the production efficiency of condoms.

[0038] Further, the display device 3 is a button display 4, which includes a display 41, a setting button 42, a detection key combination 43, and an interface switching button 44. The display 41, the setting button 42, the detection key combination 43, and the interface switching button 44 are respectively electrically connected to the data interface 23. The detection key combination 43 includes a detection start button 431 and a detection stop button 432, and the detection start button 431 and the detection stop button 432 are respectively electrically connected to the data interface 23. The display screen is used to display the capacitance value of the intelligent model of the condom electrical inspection machine. The capacitance in the intelligent model of the condom electrical inspection machine is 1 uF / 1600V, and when 1000 is displayed, it corresponds to 1 uF. The setting button is used to set the lower limit value of the capacitance. When the capacitance measured by the PLC combined measurement circuit is lower than the lower limit value, the capacitance value is displayed in red, prompting the maintenance personnel to replace the unqualified capacitor in time. In this embodiment, the lower limit value of the capacitance is set to 500. When the capacitance measured by the PLC combined measurement circuit is lower than 500, the capacitance value is displayed in red. Press the detection start button to start the detection of the capacitance in the intelligent model, and then press the detection stop button to stop the detection and complete the detection process of the capacitance in the intelligent model. Since the discharge time corresponding to a 1 uF capacitance is 1000 milliseconds, the time difference between the detection start and the detection stop should be controlled to be greater than or equal to 1.5 seconds (the displacement time of the model) during the detection. The interface switching button is used to freely switch between the capacitance display interface and the monitoring interface.

[0039] Further, it further includes an alarm device 6 and a communication platform 7. The alarm device 6 is electrically connected to the control module 22. The communication platform 7 is electrically connected to the control module 22, and the communication platform 7 is used to connect to the remote monitoring platform.

[0040] Embodiment 2:

[0041] As Figure 1 and 3As shown in the figure, an on-line detection system for the capacitance of an intelligent model of a condom electric inspection machine includes a capacitor charging and discharging circuit 1, a PLC combined measurement circuit 2, and a display device 3. The capacitor charging and discharging circuit 1 is used to be electrically connected to the capacitor in the intelligent model of the condom electric inspection machine. The capacitor is used to measure the stored electric quantity after the condom pinhole detection to determine whether the condom is qualified. The PLC combined measurement circuit 2 includes a communication module 21, a control module 22, a data interface 23, and a storage module 24. The communication module 21 is electrically connected to the control module 22. The other end of the control module 22 is electrically connected to the data interface 23. The other end of the communication module 21 is electrically connected to the capacitor charging and discharging circuit 1. The other end of the data interface 23 is electrically connected to the display device 3. The storage module 24 is electrically connected to the data interface 23. A detection instruction is sent to the PLC combined measurement circuit through the display device. The PLC combined measurement circuit receives the detection instruction through the data interface and transmits it to the control module. The control module controls the communication module to send this detection instruction to the capacitor charging and discharging circuit. After receiving the detection instruction, the capacitor charging and discharging circuit uses a 12V adjustable regulated power supply to charge the capacitor with a capacitance of 1uF / 1600V in the intelligent model of the condom electric inspection machine through a charging pile, and then discharges the capacitor, and transmits the effective signal of the discharge to the communication module. The communication module inputs it to the control module. The control module and the storage module respectively process and save the effective signal. The result is saved and re-recorded during the next test. The capacitor detection value obtained through the processing of the control module is sent to the display device, and the capacitance of each model is displayed through the display device. The adjustable power supply in the capacitor charging and discharging circuit is used in combination with the capacitor charging and discharging circuit. Through the PLC combined measurement circuit, the capacitor can be automatically detected, improving the production efficiency of condoms.

[0042] Further, the display device 3 is a touch-operable screen 5. The touch-operable screen 5 is electrically connected to the data interface 23. The touch-operable screen 5 includes a display screen 51, a preset device 52, a command sending device 53, and an interface switching device 54. The display screen 51, the preset device 52, the command sending device 53, and the interface switching device 54 are respectively electrically connected to the data interface 23. Touch screen buttons corresponding to the display screen 51, the preset device 52, the command sending device 53, and the interface switching device 54 are arranged on the touch-operable screen 5, and the functions of each device are realized by touching the above-mentioned buttons. The display device is used to display the capacitance value of the intelligent model of the condom electrical inspection machine. The capacitance in the intelligent model of the condom electrical inspection machine is 1 uF / 1600V, and displaying 1000 corresponds to 1 uF. The preset device is used to set the lower limit value of the capacitance. When the capacitance measured by the PLC combined measurement circuit is lower than the lower limit value, the capacitance value is displayed in red to prompt the maintenance personnel to replace the unqualified capacitor in time. In this embodiment, the lower limit value of the capacitor is set to 500. When the capacitance measured by the PLC combined measurement circuit is lower than 500, the capacitance value is displayed in red. A start detection instruction is sent to the PLC combined measurement circuit through the command sending device, and the on-line detection system starts to detect the capacitance in the intelligent model. A stop detection instruction is sent to the PLC combined measurement circuit through the command sending device to complete the detection process of the capacitance in the intelligent model. Since the discharge time corresponding to a 1 uF capacitor is 1000 milliseconds, the time difference between sending the start detection instruction and the stop detection instruction should be controlled to be greater than or equal to 1.5 seconds (the displacement time of the model) during detection. The interface switching device is used to freely switch between the capacitance display interface and the monitoring interface.

[0043] Further, it further includes an alarm device 6 and a communication platform 7. The alarm device 6 is electrically connected to the control module 22. The communication platform 7 is electrically connected to the control module 22. The communication platform 7 is used to connect to a remote monitoring platform.
