[0038] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0039] S1. First, add clean pure water to the immersion tank 11 in the main assembly 1 and heat it by the electric heating rod 12. The internal temperature is detected by the temperature detector 13 (the temperature detector 13 can be designed in layers according to the needs to detect the liquid temperature at different depths);

[0040] S2. The exchange membrane transported in production, such as the exchange membrane between the production transport and the winding process, passes through the delivery port of the immersion tank 11 and is attached to the conveyor roller 14 for transport movement; and the exchange membrane is exported from below or above the output shaft 47 on the hanger 46;

[0041] When the gear 23 is lowered, the gear 23 and the rack 28 are engaged with each other, and the gear 23 and the rack 28 are engaged with each other, so that the gear 23 is rotated by force, and then the gear 23 drives the wheel card 24 and the first pressure shaft 25 to turn parallel with the lowering. When the gear 23 rotates 90 degrees, the wheel card 24 contacts the wheel frame 22 and can no longer turn and rotate with the help of the gear 23, and the gear 23 is restricted and cannot turn. Then, as the wheel frame 22 descends, the gear 23 cannot turn, and the rack 28 is driven to descend by engaging with the rack 28, and the rack 28 is lowered by the lifting rod 27 at the upper limit of the lifting arm 26 to compress the spring 29; when the wheel frame 22 rises, the gear 23 and the rack 28 will move synchronously first, and the rack 28 is reset and raised with the help of the spring 29. When the spring 29 is reset, the rack 28 can no longer rise and move, and as the wheel frame 22 rises, the gear 23 is turned to cause the first pressure shaft 25 to turn to a vertical state;

[0042] S4. When the first pressing shaft 25 flips to a horizontally parallel position, the first pressing shaft 25 descends, pressing both ends of the exchange membrane downward and immersing them in the pure water in the immersion tank 11 for heating and immersion. Simultaneously, the liquid pump 35 on the bracket 34 in the flushing structure 3 generates suction, which extracts water and suspended matter at the liquid surface in the immersion tank 11 through the first pipe 6 and carries them to the filter box 31. The water is filtered through the filter screen 33 located below the cover plate in the filter box 31, and the clean liquid is supplied to the ejector body 38 by the liquid pump 35. , the ejector body 38 automatically inhales air through the flow rate change to mix gas and liquid, and then the diversion through the diverter 37 is discharged into the immersion box 11 with the help of multiple flushing pipes 36 to form a backflow, and a large number of bubbles are generated in the immersion box 11; the bubbles will float up and drive the liquid to flow, impact the exchange membrane surface and drive the solid matter and residual solvent to float up, and the solid matter will be filtered in the filter box 31; in use, the immersion box 11 can be provided with conventional settings such as a drain valve to replace the internal pure water to better clean the residual solvent;

[0043] S5. The cleaned exchange membrane is reset by the first pressure roller 25 and then conveyed rightward out of the immersion tank 11, located above the conveying seat 41 in the drying structure 4. The second electric slide 43 is then driven to drive the two second pressure rollers 45 on the mounting frame 44 downward, pressing the exchange membrane to maintain stability above the conveying seat 41. Heat is generated by the lower wall of the semiconductor cooler 492 in the temperature control assembly 49, and air is blown downward by the fan 48 through the first air guide box 493. External air enters the air inlet box 491 through the guide plate 496, fully contacts the heating wall of the semiconductor cooler 492 to increase its temperature, and is then conveyed downward for drying.

[0044] Since the cooling surface of the semiconductor refrigerator 492 requires energy conservation, an exhaust valve can be provided on the outlet end of the air pump 495, and the air pump 495 can be driven to inhale air. External air also enters the air inlet box for cooling and then enters the air pump 495 through the second air guide box 494. The air pump 495 can be discharged out of the device with the help of the exhaust valve, or can pass through the solenoid valve 39 to enter the ejector body 38 to provide a large amount of cold air, or stop driving the semiconductor refrigerator 492 to provide a single air supply to improve the gas-liquid mixing effect, thereby increasing the amount of bubbles; when cold air is provided to the ejector body 38, it can also help to control the temperature in the immersion box 11;

[0045] S6. After the air-dried exchange membrane, the cutting structure 5 can be installed by means of the conveyor seat 41 to cut the exchange membrane after drying;

[0046] For example; first, by installing the suspension rod 54 on the conveying seat 41 and fixing it with the help of fastening bolts 55, the cross-shaped slide rail 56 on the suspension rod 54 can be located above the exchange membrane, and then the collection box 51 can be installed under the conveying seat 41 with the help of the claws 53, and the collection box 51 is connected to the lower outlet; the laser cutting machine body 57 can be driven to move for cutting with the help of the cross-shaped slide rail 56, and the cut exchange membrane can be blown downward with the help of the fan 48, so that the cut exchange membrane is separated from the original base membrane and dropped into the collection box 51 for storage.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
