[0002] Aerogels are lightweight nanomaterials composed of nanoscale ultrafine particles aggregated to form a porous network structure, with gaseous dispersion media filling the pores. They exhibit a porosity as high as 99.8%, typical pore sizes ranging from 1 to 40 nm, a specific surface area of ​​400 to 1200 m² / g, and a density as low as 3 kg / m³. Their room temperature thermal conductivity can be below 0.010 W / (m·K), demonstrating excellent lightweight, light transmission, heat insulation, sound insulation, fire resistance, and impact resistance, as well as excellent chemical stability and non-flammability.

[0022] The rejection mechanism 5 in this embodiment includes a tray 501 and a rotary cylinder 505. Baffles 502 are installed on both sides of the tray 501.

The rotating shaft 503 is fixedly connected to the output end of the rotary cylinder 505. A collection box 506 is provided below one end of the tray 501.

[0023] In this embodiment, both the feeding conveyor line and the unloading conveyor line 6 include a conveyor belt 601 and a motor 606. The conveyor belt 601 is wound around the driving roller and the driven roller. The driving roller is rotatably mounted on one end of the frame 602. A synchronous pulley 603 is mounted on the shaft end of the driving roller. The synchronous pulley 603 is connected to the driving pulley 605 through a synchronous belt 604. The driving pulley 605 is mounted on the output end of the motor 606. The driven roller is rotatably mounted on one end of the frame 602. Multiple support rollers are rotatably mounted on the frame 602 between the driving roller and the driven roller. The support rollers are in contact with the conveyor belt 601 and serve to support the conveyor belt 601.

[0024] The working principle of this utility model is as follows: Multiple aerogel sheets are sequentially conveyed to the feeding mechanism 2 via a feeding conveyor line. The piston rod of cylinder 208 extends and pushes connecting plate 209 downward. Lifting plate 204, moving frame 203, and two vacuum adsorption plates 201 also move downward, so that the two vacuum adsorption plates 201 contact the two aerogel sheets on the feeding conveyor line. The vacuum pump works to remove the air inside the negative pressure chamber through the air pipe, so that the adsorption holes on the vacuum adsorption plates 201 can adsorb and fix the aerogel sheets. The piston rod of cylinder 208 retracts, causing the two vacuum adsorption plates 201 to move upward for reset. Motor 215 drives the active belt When wheel 216 rotates, the drive pulley 216 drives the transmission belt 217 to move. The transmission belt 217 drives the Z-shaped connecting plate 219 and the moving plate 210 to move along the slide rail 212, moving the two vacuum adsorption plates 201 with aerogel sheets adsorbed to above the support plate 306. The piston rod of cylinder 208 extends, causing the two vacuum adsorption plates 201 to move downwards. The vacuum pump stops working, and the two vacuum adsorption plates 201 release the aerogel sheets. The two aerogel sheets fall into the two receiving slots 307 of the support plate 306 respectively. Motor 312 drives the drive pulley 313 to rotate, and the drive pulley 313 drives the transmission belt 314 to move. The second moving belt 314 drives the second connecting plate 316 and the second moving plate 308 to move along the third sliding rail 310, moving the support plate 306 containing the aerogel sheet to one side of the sensor mounting plate 303. The Y-axis linear module 304 works to move the sensor mounting plate 303 to the support plate 306, causing the two laser sensors 301 to move above the support plate 306 and the two laser sensors 302 to move below the support plate 306. Laser sensors 301 and 302 each emit a laser beam that irradiates the surface of the two aerogel sheets, producing diffuse reflection. The reflected light spots then return to the laser sensors 301 and 302. On sensor 302, the distance between laser sensor 301 and laser sensor 302 and the aerogel sheet can be effectively obtained. Laser sensor 301 and laser sensor 302 send the detected distance information to the PLC controller. The PLC controller subtracts the distance between the laser sensor and the aerogel sheet from the distance between laser sensor 301 and laser sensor 302 to calculate the thickness of the aerogel sheet. The PLC controller sends the thickness data of the aerogel sheet to the display screen and compares the measured thickness data with the preset thickness data to determine whether the aerogel sheet is qualified, thereby realizing the measurement of the aerogel sheet.

[0025] After thickness measurement is completed, the Y-axis linear module 304 moves the sensor mounting plate 303 to reset. The Z-axis linear module 403 moves the suction cup bracket 402 and vacuum suction cup 401 downwards, bringing the vacuum suction cup 401 into contact with the aerogel sheet. The vacuum pump removes air from inside the vacuum suction cup 401 through the air pipe, allowing the vacuum suction cup 401 to adsorb and fix the aerogel sheet. The Z-axis linear module 403 moves the vacuum suction cup 401 with the adsorbed aerogel sheet upwards to reset. Motor 3 408... The drive pulley 409 rotates, which in turn drives the transmission belt 410. The transmission belt 410 then moves the connecting block 412 and the moving plate 404 along the slide rail 406, moving the vacuum suction cup 401 with the aerogel sheet adsorbed onto the tray 501. The Z-axis linear module 403 then moves the suction cup bracket 402 and the vacuum suction cup 401 downwards, allowing the vacuum suction cup 401 to move onto the tray 501. The vacuum pump stops working, and a set of suction cup components releases the aerogel sheet, which falls into the tray. On plate 501, if the aerogel sheet is qualified, the rotary cylinder 505 rotates clockwise, driving the rotating shaft 503 to rotate, causing the end of the pallet 501 carrying the aerogel sheet to swing downwards. The aerogel sheet moves along the pallet 501 to the conveyor belt 601 of the unloading conveyor line 6. The motor 606 drives the drive wheel 605 to rotate, which, under the transmission action of the synchronous belt 604, drives the synchronous wheel 603 and the drive roller to rotate. The drive roller drives the conveyor belt 601 to move, and the conveyor belt 601 carries the aerogel sheet for unloading. If the aerogel sheet is unqualified, the rotary cylinder 505 rotates clockwise. The cylinder 505 reverses, driving the rotating shaft 503 to rotate, causing the end of the pallet 501 carrying the aerogel sheet to swing upward. The aerogel sheet moves along the pallet 501 into the collection box 506, which can automatically remove unqualified aerogel sheets in a timely manner, improving the efficiency of aerogel sheet detection and classification, reducing manual labor intensity, and ensuring the product qualification rate. Another set of suction cup components releases the aerogel sheet. If the aerogel sheet is qualified, it is conveyed and unloaded through the unloading conveyor line 6. If the aerogel sheet is unqualified, it is recycled through the collection box 506.
