The working principle of the detection device of the invention is as follows: placing glue to be tested into a test board groove, namely a test area 31, heating a medium in an annular water channel 32 by a heating device (such as a water cooler/mould temperature machine) 32 to heat the glue to be tested to a preset temperature, volatilizing the glue, attaching glue volatile on a lens 21, outputting laser by a laser generator through an optical fiber 12, transmitting the laser to the transparent lens 21 through a transparent glass outer cover, and transmitting part of the laser to a power meter 41 of a rear acquisition device 4 through the lens 21; some of the laser light will be absorbed by the glue volatiles; the power parameters on the power meter 41 may be collected by a computer or display device 46. And detecting a plurality of glue samples to be detected, and combining detection results to compare the volatilization amounts of different glues, wherein the glue volatilization amounts are inversely proportional to the power displayed on the power meter. The distance between the lens 21 and the glue can be adjusted up and down by adjusting the position of the lens rotating disc 20, and the closer the lens 21 is to the glue, the more volatile matters are on the lens 21; the rotating disc 20 can also be rotated to adjust the angle of the lens 21, the more parallel the test area 31 of the glue of the lens 21, the greater the amount of volatilization of the received glue. Aiming at glue with small volatilization amount or low volatility, the volatilization amount of the glue can be increased by increasing the contact temperature of the glue and the test board, namely, the temperature of a heating medium in the annular water channel, and the glue can be realized by setting the output temperature of a mold temperature machine. The space size can be compressed by adjusting the height difference of the limiting plate 6 up and down so as to simulate the glue volatilization condition in the real scene space and restore the application scene condition in real equal proportion.

step four, adjusting the lens 21 adsorbed with the glue volatile matters to the projection direction of the output laser of the optical fiber 12, starting the laser generator 11 to output the laser from the optical fiber 12 to the lens 21, and transmitting the laser to the power meter;
and fifthly, reading the power value of the power meter 41 to obtain the parameterized index of the volatility of the glue to be tested, and recording the detection condition.
