[0028] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0029] S1. First, add pure water for cleaning into the soaking tank 11 in the main body assembly 1 and heat it up through the electric heating rod 12, and the internal temperature is detected and sensed by the temperature detector 13 (the temperature detector 13 can be designed with different levels of height according to requirements to detect the liquid temperature at different depths). S2. The exchange membrane conveyed during production, such as the exchange membrane between the production conveyance and the winding process, passes through the conveyance port of the soaking tank 11 and is conveyed and moved by fitting on the conveyance roller 14; and the exchange membrane is led out from below or above the lead-out shaft 47 on the hanging frame 46. S3. Drive the first electric slide rail 21 in the pressing-down component 2 to drive the wheel carrier 22 to descend. When the wheel carrier 22 drives the gear 23 to descend and move, the engagement of the gear 23 with the rack 28 will cause the gear 23 to be forced to rotate. Furthermore, the gear 23 drives the wheel clamp 24 and the first pressing shaft 25 to flip to parallel as they descend. When the gear 23 rotates 90 degrees, the wheel clamp 24 contacts and is limited by the wheel carrier 22 and can no longer flip and rotate by means of the gear 23, so the gear 23 is restricted from rotating. Furthermore, when the gear 23 cannot rotate as the wheel carrier 22 descends, it will drive the rack 28 to descend through the engagement with the rack 28, and the rack 28 is limited to descend on the lifting arm 26 by means of the lifting rod 27 to compress the spring 29; when the wheel carrier 22 ascends, the gear 23 and the rack 28 will move synchronously first, and the rack 28 is reset and raised by means of the spring 29. When the spring 29 is reset, the rack 28 can no longer ascend and move. Then, as the wheel carrier 22 ascends, it drives the gear 23 to flip to prompt the first pressing shaft 25 to flip to the vertical state; S4. When the first pressing shaft 25 flips to the horizontal parallel state, as the first pressing shaft 25 descends, both ends of the exchange membrane are pressed down and immersed in the pure water in the soaking tank 11 for heating and soaking; at the same time, driven by the liquid pump 35 on the support 34 in the flushing structure 3, suction is generated by the liquid pump 35, and the water and suspended substances at the liquid level in the soaking tank 11 are extracted through the first pipeline 6 and driven to the filter tank 31. They are filtered by the filter screen 33 below the cover plate in the filter tank 31, so that the clean liquid is supplied to the ejector body 38 by means of the liquid pump 35. Air is automatically sucked in through the change in the flow rate of the ejector body 38 for gas-liquid mixing, and then is discharged into the soaking tank 11 through multiple scouring pipes 36 by means of the diversion of the diverter 37 to form a reflux, and a large number of bubbles are generated in the soaking tank 11; the bubbles will float and drive the liquid to flow, impact the surface of the exchange membrane and drive the solids and residual solvents to float, and the solids will be filtered in the filter tank 31; during use, the soaking tank 11 can be provided with conventional settings such as drain valves to replace the internal pure water for better cleaning of the residual solvents; S5. After being cleaned, the exchange membrane is conveyed out of the soaking tank 11 to above the conveying seat 41 in the drying structure 4 after the first pressing shaft 25 is reset; then drive the second electric slide rail 43 to drive the two second pressing shafts 45 on the mounting frame 44 to descend and press down the exchange membrane to keep it stable above the conveying seat 41; heat is generated on the lower wall surface of the semiconductor refrigerator 492 in the temperature control component 49, and the fan 48 blows downward through the first air guide box 493. External air enters the air inlet box 491 through the guide plate 496, fully contacts and heats up with the heating wall surface of the semiconductor refrigerator 492, and then is conveyed downward for drying use; Since the cooling surface of the semiconductor cooler 492 requires energy conservation, an exhaust valve can be provided at the air outlet end of the air pump 495, and the air pump 495 can be driven to suck air. The 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 discharge the air outside the device through the exhaust valve, or the air can pass through the solenoid valve 39 and enter the injector body 38 to provide a large amount of cold air, or stop driving the semiconductor cooler 492 to provide only air to improve the air-liquid mixing effect, thereby increasing the amount of bubbles. When cold air is provided to the injector body 38, it can also help control the temperature in the soaking tank 11. S6. The air-dried exchange membrane can also be installed with the cutting structure 5 by means of the conveying seat 41 to perform cutting processing on the dried exchange membrane. For example, first install the suspension rod 54 on the conveying seat 41 and fix it with the fastening bolt 55, so that the cross-shaped slide rail 56 on the suspension rod 54 is located above the exchange membrane. Then install the collection box 51 under the conveying seat 41 with the claw 53, and the collection box 51 is communicated with the lower discharge port. Then the laser cutting machine main body 57 can be driven to move for cutting by means of the cross-shaped slide rail 56, and the cut exchange membrane is blown downward by the fan 48, so that the cut exchange membrane is separated from the original base film and descends into the collection box 51 for storage.
