The foil conveyor belt 7 is thin, and the rotating shaft 5 may slip when driving the foil conveyor belt 7 to rotate, causing the foil conveyor belt 7 to pause, so that the carbon source may produce defects due to the pause. When the rotating shaft 5 and the rotating roller 6 rotate at the same time, the rotating shaft 5 and the rotating roller 6 will drive the foil conveyor belt 7 to rotate at the same time, so that the foil conveyor belt 7 does not need to drive the rotating roller 6 to rotate, and the rotating roller 6 can drive the foil conveyor belt 7 to rotate, so that the device is not prone to failure. ;
[0025] Working principle: by placing the carbon source on the foil conveyor belt 7; the motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the foil conveyor belt 7 to rotate, and at the same time the rotating roller 6 is rotated, so that the foil conveyor belt 7 drives the carbon source to move, at this time, the double-threaded rotating rod 11 is rotated, so that the rotation of the double-threaded rotating rod 11 drives a pair of limit blocks 10 to move toward the center at the same time, thereby clamping and limiting the carbon source, the limit block 10 only limits the carbon source, not fixed, at this time the carbon source will be limited by the pair of limit blocks 10, so that it is located in the middle of the foil conveyor belt 7 and cannot move, so that the carbon source is moved to the bottom of the laser scanning device 3 for laser thermal effect to generate a graphene layer, so that the device can ensure that the carbon source is accurately located below the laser scanning device 3, so that the carbon source can be effectively utilized, without The worm 15 is driven to rotate by rotating the worm 16, and the rotation of the worm 15 drives the rotating rod 13 to rotate, thereby driving the first gear 14 to rotate. Because the first gear 14 is matched with a group of tooth grooves 12, the rotation of the first gear 14 drives the sliding plate 2 to move up and down on one side of the inner wall of the base 1, thereby driving the laser scanning device 3 to move up and down, so that the device can adjust the focusing point of the laser scanning device 3 according to the size, thickness and properties of the carbon source, so that the device can scan different carbon sources by adjusting the height of the laser scanning device 3, thereby increasing the use range of the device, and the worm 16 can drive the worm wheel 15 to rotate, and the worm wheel 15 cannot drive the worm 16 to rotate, so that after the position of the device is adjusted using the worm 16, The worm gear 15 drives the worm 16 to rotate, so that the laser scanning device 3 will not move due to external force. From the perspective of determining the stability of the laser scanning device 3 during scanning, the slider 19 is ejected by the spring, so that the slider 19 drives the circular roller 20 to fall, so that the circular roller 20 presses down on the carbon source on the foil conveyor belt 7, so that the carbon source can be moved by the foil conveyor belt 7 while being pressed by the circular roller 20, so that when the carbon source moves, the wrinkles are flattened due to being pressed by the circular roller 20, so that the carbon source will not have defects due to wrinkles during scanning, thereby causing problems with the laser thermal effect, so that when the device performs laser thermal effect on the carbon source, some possible problems are taken into consideration, so that the carbon source can be kept in the best state to be scanned by the laser scanning device 3 Laser thermal effect is used to produce graphene. By rotating the first threaded rod 21, the first threaded rod 21 can be moved up and down, thereby driving the square shell 17 to move up and down, so that when the device uses the circular roller 20 to flatten carbon sources of different thicknesses and properties, the position of the circular roller 20 and the elastic force of the elastic member 18 can be adjusted, so that the carbon source can be driven by the foil conveyor belt 7 to move while the carbon source can be pressed most effectively, so that it is not easy to wrinkle, thereby making the device more flexible and more applicable. By pressing the carbon source with the circular roller 20, some dust and impurities on the carbon source, as well as dust contaminated by the circular roller 20 when it is idle, will be moved when the carbon source drives the circular roller 20 to rotate. Because one side of the outer wall of the scraper 22 contacts the outer side wall of the circular roller 20,The scraper 22 scrapes off the dust and impurities on the outer wall of the circular roller 20, so that the dust slides along the inclined surface of the scraper 22 to the turning point of the scraper 22 and is stored. Although the movement of the carbon source cannot effectively drive the circular roller 20 to move, it will drive the circular roller 20 to rotate from time to time, so that the dust and impurities can be collected, and the scraper 22 is fixed by bolts 23, so that the scraper 22 can be removed and cleaned when the device is idle, so that the scraper 22 ensures the cleanliness of the circular roller 20, and the circular roller 20 removes the dust on the carbon source, and the rotating shaft 5 and the rotating roller 6 can rotate in the same direction at the same time due to a pair of sprockets 25 and chains 26. The rotating roller 6 is driven by the rotating shaft 5 to move the foil conveyor belt 7, so the rotating roller 6 itself does not drive the foil conveyor belt 7 to rotate. The foil conveyor belt 7 is thin, and the rotating shaft 5 may slip when driving the foil conveyor belt 7 to rotate, causing the foil conveyor belt 7 to pause, so that the carbon source may produce defects due to the pause. The rotating shaft 5 and the rotating roller 6 rotate at the same time, which will drive the foil conveyor belt 7 to rotate at the same time, so that the foil conveyor belt 7 does not need to drive the rotating roller 6 to rotate, while the rotating roller 6 can drive the foil conveyor belt 7 to rotate, so that the device is not prone to failure.
