[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 The capacitor low-voltage corrosion aluminum foil electrolytic treatment device provided by this utility model includes a base 1 and an unwinding shaft 2.

[0027] Reference Figure 1 - Figure 3 As shown, a unwinding shaft 2 is installed on one side of the base 1, and an electrolysis structure 3 is provided on one side of the base 1. The electrolysis structure 3 includes an electrolysis cell 301 located on one side of the base 1. A protective shaft 302 is installed at the top of each electrolysis cell 301. A power supply 303 is installed on the outside of the electrolysis cell 301. Conductive rollers 304 are evenly arranged on one side of the power supply 303. Titanium pillars 305 are evenly installed on the side of the power supply 303 away from the conductive rollers 304. A heat exchanger 306 is installed inside the electrolysis cell 301. A temperature sensor 307 is installed on the inner wall of the electrolysis cell 301. The protective shafts 302 are symmetrically distributed at the top of the electrolysis cell 301. The conductive rollers 304 extend into the interior of the electrolysis cell 301. The titanium pillars 305 extend into the interior of the electrolysis cell 301. The conductive rollers 304 and titanium pillars 305 are symmetrically distributed on one side of the power supply 303. A microcontroller is externally connected to the temperature sensor 307. The output terminal of the microcontroller is electrically connected to the input terminal of the heat exchanger 306.

[0028] During the production and processing of capacitor aluminum foil, it needs to undergo electrolytic etching to electrochemically corrode and form a porous structure, increasing the surface area by tens to hundreds of times to improve the performance of the capacitor aluminum foil. During electrolysis, an electrolytic structure 3 is incorporated, ensuring that the aluminum foil enters the electrolytic cell 301 while protective shafts 302 are fixed on both sides of the top of the electrolytic cell 301 to prevent scratches or other damage during entry. The top of the aluminum foil also abuts against the bottom of the conductive roller 304. The conductive roller 304 conducts electrical conductivity to the aluminum foil, and the conductive roller 304 is connected to the positive terminal of the power supply 303. The titanium pillar 305 is connected to the negative terminal of the power supply 303, thereby meeting the electrolysis requirements. The temperature of the solution inside the electrolytic cell 301 is changed by the heat exchanger 306 and monitored by the temperature sensor 307. The microcontroller connected to the temperature sensor 307 controls the heat exchanger 306 at all times to keep the temperature inside the electrolytic cell 301 at the appropriate electrolysis temperature, thereby greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a winding motor 4 is installed on one side of the base 1, and a winding shaft 5 is provided on one side of the winding motor 4. A cleaning structure 6 is provided on one side of the base 1. The cleaning structure 6 includes a cleaning tank 601 provided on one side of the base 1.

The reserved slots 604 are evenly distributed at the top of the drying seat 603. The guide shafts 606 are symmetrically distributed on both sides of the drying seat 603.

[0030] After electrolytic etching of aluminum foil, a cleaning structure 6 is provided to facilitate the cleaning and drying of the aluminum foil surface. The aluminum foil is washed by water through the cleaning tank 601 via the fixed shaft 602. The washed aluminum foil is then passed through the drying seat 603 and dried by the electric hot air blower 605 inside the pre-reserved groove 604 at the top of the drying seat 603. This prevents oxidation of the aluminum foil during storage and transportation, thereby protecting the aluminum foil and improving its performance. This greatly increases the practicality of the device.
