[0017] (1) The invention sets a cleaning device to pull the sliding rod backward, and the sliding rod drives the horizontal frame to move toward the front of the frame, and the horizontal frame drives the cleaning plate to move toward the front of the frame. The cleaning plate scrapes the impurities on the surface of the ion exchange membrane toward the front of the frame. The flexible setting of the cleaning plate can prevent the surface of the ion exchange membrane from being scratched. The setting of the cleaning plate can effectively remove impurities on the surface of the ion exchange membrane, and at the same time avoid scratching the surface of the membrane, thereby ensuring the surface integrity and cleanliness of the membrane during the detection process. The cleaning plate and the curved sliding rod contact the spring piece 1 and the spring piece 2 respectively, and then reset to the left. The cleaning plate can move left and right while moving toward the front. This multi-directional movement allows the cleaning plate to more comprehensively cover the surface of the ion exchange membrane, thereby further effectively removing impurities on the surface, and further improving the cleaning efficiency and protection.

[0018] (2) The invention pushes the manual plate downward through the setting of the compacting device, and the manual plate drives the connecting plate to move downward, and the connecting plate drives the vertical rod to move downward, and the vertical rod drives the compacting frame to move downward. After the compacting frame moves to the bottom, the handles on the square rod are pulled to both sides, and the square rod drives the fixed rod to move to both sides, and the fixed rod drives the pushing plate to move to both sides. The pushing plate flattens the wrinkles on the surface of the ion exchange membrane, which can effectively flatten the wrinkles on the surface of the ion exchange membrane, and can reduce the error in the detection process, so that the performance evaluation of the ion exchange membrane is more accurate, thereby ensuring its effect and safety in practical applications, so that the resistance block drives the lower pressure plate to move downward slightly, and the lower pressure plate fixes the flattened ion exchange membrane at both ends to prevent the elastic deformation of the ion exchange membrane from being reset, and the return spring can pull the lower pressure plate upward to return to its original position after the pushing plate is reset. Through the setting of the lower pressure plate, the ion exchange membrane is effectively prevented from being reset due to elastic deformation after being flattened, thereby preventing wrinkles from being generated again, thereby ensuring the flatness and stability of the membrane surface.

[0019] (3) The present invention provides a sealing device. The upper mold drives the connecting frame to move downward, and the connecting frame drives the sealing ring to move downward. The sealing ring seals the surface of the ion exchange membrane, thereby achieving effective sealing of the surface of the ion exchange membrane and preventing any possible leakage during subsequent operation or use. This ensures the accuracy of the ion exchange membrane integrity test. The bottom of the sealing ring is soaked with liquid, and the test pump and the air tightness tester are turned on. The test pump transports gas through the upper air pipe to the space between the lower mold and the ion exchange membrane. The air tightness tester records the air pressure between the lower mold and the ion exchange membrane. The water in the water bag overflows to the space between the connecting frame and the ion exchange membrane. By increasing the air pressure, it is observed whether bubbles appear on the water on the top of the ion exchange membrane, thereby judging whether there are large holes on the surface of the ion exchange membrane. The gap between the sealing ring and the ion exchange membrane is soaked and filled, thereby enhancing the sealing effect. This ensures that the sealing performance of the sealing ring can be further enhanced while applying pressure, and provides accurate data for subsequent tests. BRIEF DESCRIPTION OF THE DRAWINGS

The air tightness detector 14 records the air pressure between the lower mold 11 and the ion exchange diaphragm 111, and the water in the water bag 43 overflows to between the connecting frame 41 and the ion exchange diaphragm 111. By increasing the air pressure, observe whether bubbles appear on the water on the top of the ion exchange diaphragm 111, so as to judge whether there are large holes on the surface of the ion exchange diaphragm 111, and the gap between the sealing ring 42 and the ion exchange diaphragm 111 can be infiltrated and filled, thereby enhancing the sealing effect, ensuring that the sealing of the sealing ring 42 can be further enhanced while applying pressure, and providing accurate data for subsequent tests.

[0039] When the pushing plate 37 moves to the front of the embedded cavity of the compacting frame 32, the inclined block 311 on the square rod 35 will abut against the abutment block 310, so that the abutment block 310 drives the lower pressure plate 38 to move downward slightly. The lower pressure plate 38 fixes the flattened ion exchange membrane 111 at both ends to prevent the elastic deformation of the ion exchange membrane 111 from resetting. The return spring 39 can pull the lower pressure plate 38 back to its original position after the pushing plate 37 is reset. The setting of the lower pressure plate 38 effectively prevents the ion exchange membrane 111 from resetting due to elastic deformation after being flattened, thereby preventing wrinkles from occurring again, thereby ensuring the flatness and stability of the membrane surface.

[0040] When the compaction frame 32 is compacted and fixed, the cylinder 16 is started, and the cylinder 16 drives the upper mold 17 to move downward, and the upper mold 17 drives the connecting frame 41 to move downward, and the connecting frame 41 drives the sealing ring 42 to move downward, and the sealing ring 42 seals the surface of the ion exchange membrane 111, thereby achieving effective sealing of the surface of the ion exchange membrane 111, preventing any possible leakage during subsequent operation or use, and ensuring the accuracy of the ion exchange membrane integrity detection.

[0041] When the upper mold 17 moves downward, the upper mold 17 drives the middle-shaped extrusion plate 47 to move downward, and the middle-shaped extrusion plate 47 contacts the top of the compaction frame 32, so that the middle-shaped extrusion plate 47 squeezes the water bag 43 upward, and the water inside the water bag 43 flows to the inside of the water outlet pipe 45 through the water outlet thick pipe 46, flows to the inside of the water storage cavity of the sealing ring 42 through the water outlet pipe 45, and then is discharged through the flow hole of the sealing ring 42. The rubber material of the sealing ring 42 contacts the surface of the ion exchange membrane 111 to produce a slight gap, and the bottom of the sealing ring 42 is soaked by the liquid, and the test pump 12 and the air tightness detector 14 are turned on. The test pump 12 transmits gas through the upper air pipe 13. The airtightness detector 14 records the air pressure between the lower mold 11 and the ion exchange membrane 111, and the water in the water bag 43 overflows to between the connecting frame 41 and the ion exchange membrane 111. By increasing the air pressure, it is observed whether bubbles appear on the water on the top of the ion exchange membrane 111, so as to judge whether there are large holes on the surface of the ion exchange membrane 111. The gap between the sealing ring 42 and the ion exchange membrane 111 is infiltrated and filled, thereby enhancing the sealing effect, ensuring that the sealing performance of the sealing ring 42 can be further enhanced while applying pressure, and providing accurate data for subsequent tests.
