[0020] When the reverse osmosis membrane needs to be inspected, the staff first places the reverse osmosis membrane on the top of the loading platform 6, and then starts the loading device 2. The hydraulic rod at one end of the bottom of the bottom plate 203 drives the multiple vacuum suction cups 204 to move downward. When the vacuum suction cups 204 come into contact with the reverse osmosis membrane, the vacuum suction cups 204 are started to adsorb the reverse osmosis membrane, and then the hydraulic rod drives the vacuum suction cups 204 and the reverse osmosis membrane to move upward and reset.
[0021] Next, the rotary cylinder 201 is started, which drives the rotating shaft 202 to rotate 180 degrees. The rotating shaft 202 drives the bottom plate 203 to rotate. The bottom plate 203 drives the vacuum suction cup 204 and the reverse osmosis membrane to rotate 180 degrees, so that the reverse osmosis membrane is located on top of the optical glass 8. Finally, the vacuum suction cup 204 and the reverse osmosis membrane are driven downward by the hydraulic rod, so that the reverse osmosis membrane is placed on top of the optical glass 8.
[0022] Next, the circular conveyor 7 is started, and the circular conveyor 7 will drive the optical glass 8 and the reverse osmosis membrane to pass through the top backlight detection device 10, the front light source detection device 11 and the bottom backlight detection device 12 in sequence. Through the top backlight detection, front detection and bottom backlight detection of the reverse osmosis membrane, it is judged whether it is qualified. The qualified products are adsorbed by the feeding device 2 and placed inside the qualified product placement table 4, and the unqualified products are adsorbed by the feeding device 2 and placed inside the unqualified product placement table 5 for classification and storage;

The detection station is divided into three stations, namely the top backlight detection device 10, the front light source detection device 11 and the bottom backlight detection device 12. Each detection station is equipped with an RFID reader for transmitting the detection data to the inside of the RFID tag 18, so as to judge whether the reverse osmosis membrane is qualified through the detection data.
[0027] Working principle: By starting the feeding device 2, the hydraulic rod at the bottom of the bottom plate 203 is activated to drive multiple vacuum suction cups 204 to move downward, and at the same time the vacuum suction cups 204 are activated to adsorb the reverse osmosis membrane. Then the hydraulic rod drives the vacuum suction cups 204 and the reverse osmosis membrane to move upward and reset. Then the rotary cylinder 201 is activated. The rotary cylinder 201 drives the rotating shaft 202, the bottom plate 203, the vacuum suction cups 204 and the reverse osmosis membrane to rotate 180 degrees, so that the reverse osmosis membrane is located on the top of the optical glass 8. The hydraulic rod drives the vacuum suction cups 204 and the reverse osmosis membrane downward to move the reverse osmosis membrane back to the original position. The osmosis membrane is placed on the top of the optical glass 8, and then the ring conveyor 7 is started. The ring conveyor 7 will drive the optical glass 8 and the reverse osmosis membrane to pass through the top backlight detection device 10, the front light source detection device 11 and the bottom backlight detection device 12 in sequence. The RFID reader / writer set at each detection station will transmit the detection data to the inside of the RFID tag 18 to determine whether the reverse osmosis membrane is qualified.
