The manufacturing process of etching foil integrates multiple disciplines and technologies such as mechanics, electronics, chemical engineering, and metal materials. Ultra-high voltage etching foil is part of the cost structure of aluminum electrolytic capacitors and has very high added value. When producing ultra-high voltage etching foil, production equipment is required to dry the etching foil.

This prevents the real-time adsorption of water vapor formed when the moisture on the ultra-high voltage etched foil evaporates due to heating. Consequently, the water vapor eventually re-attaches to the ultra-high voltage etched foil, greatly affecting the drying effect.

[0012] A manufacturing process for an ultra-high voltage etched foil production equipment for aluminum electrolytic capacitors includes the following steps:

[0013] S1. The wiping cotton will wipe away the moisture on the corrosion foil body in advance, and the user will turn on the heater and air pump through the controller. At this time, the air pump will transfer the heat generated in the heater to the loop pipe through the three-way pipe, and spray it onto the surface of the corrosion foil body through multiple sets of nozzles to dry the corrosion foil body. At this time, the moisture on the corrosion foil body will evaporate to form water vapor. The moisture-absorbing sponge will absorb the water vapor in the drying box in real time. After a certain period of absorption, the moisture-absorbing sponge needs to be replaced. At this time, the user will turn on the auxiliary motor through the controller. The auxiliary motor will drive the tilting frame to rotate, thereby pushing the sealing plate to move up and seal the square hole. Then, the user will open the first solenoid valve through the controller to release the closed state of the pressure relief pipe. At this time, the heat and water vapor above the horizontal plate will be discharged through the pressure relief pipe.

[0014] S2. Then, the user turns on the first motor through the controller. The first motor drives the disc to rotate, which in turn drives multiple docking plates and multiple top frames to rotate, thereby quickly replacing the moisture-absorbing sponge that has absorbed moisture with the moisture-absorbing sponge that has not absorbed moisture. At this time, the moisture-absorbing sponge that has absorbed moisture rotates out of the drying box and moves to the top of the placement frame. After the conversion is completed, the user controls the sealing plate to descend. At this time, the new moisture-absorbing sponge can continuously absorb moisture in the drying box.

[0015] S3. Then, the user opens the electric slide rail slide through the controller and presets the reciprocating stroke of the electric slide rail slide, thereby driving the moving frame, support plate, square column and squeezing column to move back and forth. The elastic rebound of the first spring gives the squeezing column a certain squeezing force, so that the squeezing column can continuously stick to the moisture-absorbing sponge that is full of moisture. At this time, the squeezing column will fully squeeze the water absorbed in the moisture-absorbing sponge. The squeezed water will enter the protective cover. At this time, the second solenoid valve opens, and the water will be discharged through the drain pipe and fall into the placement frame for collection.

[0016] S4. Subsequently, the user activates the second motor via the controller. The second motor controls the swing angle of the Z-shaped drive frame, thereby driving the protective cover to move upward and completely cover the moisture-absorbing sponge after squeezing out the water, in cooperation with the strip frame. At this time, the user activates the third solenoid valve via the controller to release the closed state of the auxiliary pipe. The heat in the three-way pipe will be transported to the protective cover through the auxiliary pipe, telescopic pipe and horizontal pipe to quickly dry the moisture-absorbing sponge after squeezing, making it convenient for continued use next time and ensuring the sustainability of the entire auxiliary component.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The design of the moisture-absorbing sponge facilitates real-time adsorption of moisture in the drying chamber, preventing moisture accumulation from affecting the drying effect on the corrosion foil. The L-shaped sealing plate design facilitates the sealing of the U-shaped groove, preventing heat leakage. Furthermore, the use of a first motor as the drive source allows for easy repositioning of multiple sets of moisture-absorbing sponges as needed, enabling rapid replacement of saturated and unabsorbed sponges. This ensures continuous adsorption of moisture in the drying chamber, improving the moisture absorption effect.

[0019] 2. The electric slide rail design facilitates the repositioning of the extrusion column. The elastic rebound of the first spring provides a certain squeezing force to the extrusion column, ensuring it remains in close contact with the moisture-absorbing sponge. This allows for complete extraction of moisture from the sponge. A second motor provides the drive source, enabling control of the Z-shaped drive frame's swing angle. Combined with the strip frame, this allows for easy adjustment of the protective cover's height, ensuring complete coverage of the squeezed-out sponge. Furthermore, the auxiliary tube, telescopic tube, and horizontal tube facilitate heat transfer into the protective cover, rapidly drying the squeezed-out sponge for reuse. This ensures the sustainability of the entire auxiliary assembly and facilitates continuous, real-time moisture absorption.

[0020] 3. By setting square holes, moisture and heat can be moved upward normally. With the help of an auxiliary motor, the position of the sealing plate can be changed easily with the help of the flipping frame. This allows the upper part of the drying chamber to be quickly sealed when the moisture-absorbing sponge needs to be switched. With the help of the pressure relief pipe, the heat can be quickly discharged, avoiding the large amount of heat discharged when the moisture-absorbing sponge is switched, which would affect the temperature inside the drying chamber.

At this time, the moisture on the corrosion foil body 3 will evaporate to form water vapor. The moisture-absorbing sponge 27 will absorb the water vapor in the drying box 1 in real time. After a certain period of absorption, the moisture-absorbing sponge 27 needs to be replaced. At this time, the user will turn on the auxiliary motor 20 through the controller. The auxiliary motor 20 will drive the flipping frame 19 to rotate, thereby pushing the sealing plate 18 to move up and seal the square hole 14. Then, the user will turn on the first solenoid valve 12 through the controller to release the closed state of the pressure relief pipe 11. At this time, the heat and water vapor above the horizontal plate 13 will be discharged through the pressure relief pipe 11.

[0036] S2. Subsequently, the user turns on the first motor 23 through the controller. At this time, the first motor 23 drives the disc 24 to rotate, thereby driving multiple docking plates 25 and multiple top frames 26 to rotate, thereby quickly replacing the moisture-absorbing sponge 27 that has absorbed moisture with the moisture-absorbing sponge 27 that has not absorbed moisture. At this time, the moisture-absorbing sponge 27 that has absorbed moisture rotates out of the drying box 1 and moves to the top of the placement frame 6. After the conversion is completed, the user controls the sealing plate 18 to descend. At this time, the new moisture-absorbing sponge 27 can continuously absorb moisture in the drying box 1.

[0037] S3. Subsequently, the user activates the electric slide rail 33 through the controller and presets the reciprocating stroke of the electric slide rail 33, thereby driving the moving frame 34, support plate 35, square column 37 and squeezing column 38 to move back and forth. The elastic rebound of the first spring 40 gives the squeezing column 38 a certain squeezing force, so that the squeezing column 38 can continuously stick to the moisture-absorbing sponge 27 that is full of moisture. At this time, the squeezing column 38 squeezes the water absorbed in the moisture-absorbing sponge 27 back and forth. The squeezed water will enter the protective cover 41. At this time, the second solenoid valve 43 opens, and the water will be discharged through the drain pipe 42 and fall into the placement frame 6 for collection.

[0038] S4. Subsequently, the user activates the second motor 46 via the controller. The second motor 46 controls the swing angle of the Z-shaped drive frame 47, thereby driving the protective cover 41 to move upward and completely cover the moisture-absorbing sponge 27 after squeezing out the water, in cooperation with the strip frame 48. At this time, the user activates the third solenoid valve 53 via the controller to release the closed state of the auxiliary pipe 52. At this time, the heat in the three-way pipe 9 will be transported to the protective cover 41 through the auxiliary pipe 52, the telescopic pipe 51 and the horizontal pipe 49, which will quickly dry the moisture-absorbing sponge 27 after squeezing, making it convenient for the next use and ensuring the sustainability of the entire auxiliary component.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 23, the second motor 46, the auxiliary motor 20, the heater 7, the air pump 8, the electric slide rail 33, the first solenoid valve 12, the second solenoid valve 43, the third solenoid valve 53, and the controller are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
