[0020] The working principle of the online detection device for the thickness of waterproof coiled material of the utility model includes:

[0021] The roll material conveying device conveys and guides the waterproof roll material 4 to intermittently pass on the top surface of the measuring platform 1;

[0022] Each time the waterproofing coiled material 4 stops passing on the top surface of the measuring platform 1, the coiled material pressing and positioning device 2 presses down and positions the waterproofing coiled material 4 on the measuring platform 1, and the coiled material thickness measuring device 3 measures the thickness of the waterproofing coiled material 4 on the measuring platform 1 and obtains the coiled material thickness measurement data; when the coiled material thickness measurement data exceeds the predetermined thickness data range, the main control device determines that the waterproofing coiled material 4 is a defective product, and triggers the defective product alarm device to sound an alarm;

[0023] After each measurement by the roll material thickness measuring device 3 is completed, the roll material thickness measuring device 3 is separated from the waterproof roll material 4 on the measuring platform 1, the roll material downward pressing positioning device 2 releases the downward pressing positioning of the waterproof roll material 4 on the measuring platform 1, and the roll material conveying device continues to convey the waterproof roll material 4;

[0024] The roll material pressing and positioning device 2 presses and positions the waterproof roll material 4 on the measuring platform 1, including the following steps: the second cylinder 26 drives the second lifting frame 22 to move downward, and the second lifting frame 22 drives the pressing plate 21 to move downward until the pressing plate 21 presses and positions the waterproof roll material 4 on the top surface of the measuring platform 1; the existence of the second spring 25 can prevent the waterproof roll material 4 from being deformed due to the excessive pressure applied by the pressing plate 21 to the waterproof roll material 4 on the measuring platform 1 (that is, to prevent the waterproof roll material 4 from being deformed due to the excessive pressure applied by the roll material pressing and positioning device 2 to the waterproof roll material 4 on the measuring platform 1);
