[0022] Example

[0023] Please see Figure 1 This application provides an online monitoring system for corrosion-prone foil production. The online monitoring system for corrosion-prone foil production according to this embodiment includes a foil feeding device 1, a foil receiving device 2, a foil buffer device 3, an electrolytic cell 4, a drying furnace 5, a foil collecting device 6, and an online foil quality monitoring device 7. The foil feeding device 1, foil receiving device 2, electrolytic cell 4, drying furnace 5, and foil collecting device 6 are arranged sequentially. The foil buffer device 3 includes a first buffer device 31 and a second buffer device 32. The first buffer device 31 is located between the foil receiving device 2 and the electrolytic cell 4, and the second buffer device 32 is located between the drying furnace 5 and the foil collecting device 6. The online foil quality monitoring device 7 is located between the drying furnace 5 and the foil collecting device 6.

[0024] When the online monitoring system for the etched foil production system is in operation, the foil roll is placed on the foil feeding device 1. The foil feeding device 1 releases the foil sheet, which then passes sequentially through the foil receiving device 2, the first buffer device 31, the electrolytic cell 4, the drying furnace 5, and the second buffer device 32 before being wound up by the foil receiving device 6. The foil receiving device 2 connects the foil sheets of the previous foil roll to the next foil roll when the foil feeding device 1 changes foil rolls, preventing the foil sheets from breaking during the change. The foil buffer device 3 is used to reserve foil sheets during foil roll changes to prevent the production system from being interrupted. After passing through the drying furnace 5, the foil sheet also passes through the foil sheet quality online monitoring device 7, which measures the voltage of the etched foil sheet in real time, thereby monitoring the quality of the foil sheet.

[0025] The foil quality online monitoring device 7 of this embodiment includes a conductive roller 70, an online monitoring circuit 71, and a data processing unit. The conductive roller 70 includes a first conductive roller 701 and a second conductive roller 702. The first conductive roller 701 is located at the rear end of the drying oven 5, and the second conductive roller 702 is located at the front end of the foil collecting device 6. A measurement area R1 is formed between the first conductive roller 701 and the second conductive roller 702. The online monitoring circuit 71 is electrically connected to both the first conductive roller 701 and the second conductive roller 702, and the data processing unit is electrically connected to the online monitoring circuit 71.

[0026] When the foil quality online monitoring device 7 is working, the foil, after being etched and dried, passes sequentially over the first conductive roller 701 and the second conductive roller 702; the online monitoring circuit 71 provides voltage to the first conductive roller 701 and the second conductive roller 702, and measures the voltage of the foil between the first conductive roller 701 and the second conductive roller 702, thereby monitoring the quality of the foil in real time during the production process.

[0027] Further, the online monitoring circuit 71 includes a precision resistor R2, a voltage divider resistor R3, a voltage sensor V1, and a power supply U. The measurement area R1 formed by the first conductive roller 701 and the second conductive roller 702 is connected in series with the precision resistor R2, the voltage divider resistor R3, and the power supply U. The voltage sensor V1 is connected in parallel with the precision resistor R2. In some embodiments, the first conductive roller 701 is connected to the positive terminal of the power supply U. When the online monitoring circuit 71 is working, the power supply U provides current, which flows into the first conductive roller 701, then through the foil under test in the measurement area R1 formed by the first conductive roller 701 and the second conductive roller 702, then through the second conductive roller 702, into the precision resistor R2, and finally through the voltage divider resistor R3 back to the negative terminal of the power supply U. The voltage sensor V1 detects the voltage across the precision resistor R2 and sends the measured voltage to the data processing unit for calculation. After calculation, the voltage value across the foil under test can be obtained.

[0028] voltage value ;

[0029] By comparing the voltage values ​​across the foil under test with a preset voltage value, it is possible to determine whether the resistance of the foil under test deviates from the preset range, thereby enabling real-time monitoring of the production quality of the etched foil.

[0030] In some embodiments, the foil quality online monitoring device further includes a cloud database, which is signal-connected to the data processing unit. The data processing unit processes the data and stores it in the cloud database. Based on the data in the cloud database, an AI model is integrated, and by retrieving data from the cloud database, training and learning, the optimal production parameters for foil production are processed and derived.

[0031] In some embodiments, the foil buffer device 3 includes a positioning roller, a sliding roller 31a, and a sliding base 32a. Further, the positioning roller includes a first positioning roller 301 and a second positioning roller 302, which are respectively disposed on both sides of the sliding base 32a; in some embodiments, the first positioning roller 301 and the second positioning roller 302 are symmetrically arranged about the sliding base 32a as an axis of symmetry. The sliding roller 31a is slidably disposed on the sliding base 32a. The foil passes over the first positioning roller 301, then over the sliding roller 31a, and then over the second positioning roller 302. By changing the position of the sliding roller 31a, the length of the foil between the first positioning roller 301 and the second positioning roller 302 can be changed.

[0032] Before the foil feeding device 1 needs to replace the foil roll, the sliding roller 31a of the first buffer device 31 slides towards the sliding base 32a away from the first positioning roller 301 and the second positioning roller 302, thereby increasing the length of the foil between the first positioning roller 301 and the second positioning roller 302. When the foil feeding device 1 replaces the foil roll, the sliding roller 31a slides towards the sliding base 32a closer to the first positioning roller 301 and the second positioning roller 302, gradually releasing the foil reserved between the first positioning roller 301 and the second positioning roller 302 for subsequent processes, ensuring the operation of the entire system. When the foil take-up device 6 changes the foil roll, the sliding roller 31a of the second buffer device 32 slides toward the end of the sliding base 32a away from the first positioning roller 301 and the second positioning roller 302, thereby increasing the length of the foil between the first positioning roller 301 and the second positioning roller 302 to accommodate the foil provided by the front-end process and ensure the operation of the entire system. When the foil take-up device 6 changes the foil roll, the sliding roller 31a resets and releases the foil retained between the first positioning roller 301 and the second positioning roller 302.

[0033] Furthermore, the first conductive roller 701 is disposed at the front end of the first positioning roller 301 of the second buffer device 32, and the second conductive roller 702 is disposed at the rear end of the second positioning roller 302 of the second buffer device 32. By disposing the second buffer device 32 between the first conductive roller 701 and the second conductive roller 702, the contact stability between the foil and the first conductive roller 701 and the second conductive roller 702 can be ensured when the second buffer device 32 is in operation, thereby improving the reliability of real-time monitoring.

[0034] In some embodiments, the foil splicing device 2 includes a foil pressing device and a foil splicing detection device. The foil pressing device includes an upper pressure plate and a lower pressure plate, which are arranged parallel to each other to form a foil pressing channel. The foil splicing detection device is located beside the foil pressing channel and is used to detect the position of the foil sheet and determine whether the foil sheets overlap. In some embodiments, the foil splicing detection device is an infrared detector. During operation, the foil sheet passes through the foil pressing channel. When the foil unloading device 1 changes the foil roll, the tail end of the front foil sheet stays in the foil pressing channel. When the foil splicing detection device detects that the front end of the new foil sheet has been sent into the foil pressing channel and overlaps with the front foil sheet, the upper pressure plate and the lower pressure plate close together to press the foil sheet together.

[0035] The online monitoring system for corrosion foil production of this utility model uses an online foil quality monitoring device 7 to monitor the voltage between the first conductive roller 701 and the second conductive roller 702 in real time, thereby achieving real-time monitoring of the quality of the produced corrosion foil without the need for random sampling of finished products. This improves detection efficiency and quality, and reduces damage to the finished product.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
