The working principle of the goggles light transmittance measuring device provided by the embodiment is as follows: as shown in fig. 1, the initial positions of the components of the device are that a stack of lenses 103 is put into a limit box 503 and is arranged above a support column 501, a fixing plate 301 is positioned at the outer side of the limit box 503, and a squeezing block 302 is abutted with the limit box 503; then, the cylinder 504 is started to drive the supporting plate 502 to move downwards, the supporting plate 502 drives the limiting box 503 to move downwards, and when the first lens 103 is completely exposed out of the limiting box 503, the first extrusion block 302 is separated from the limiting box 503.
Then the extrusion block 302 approaches the lens 103 under the action of the second elastic piece 313 and pushes the lens 103 to slide, the other side surface of the lens 103 moves to the upper side of the second sliding plate 310 (as shown in fig. 7), the lens 103 slides and slides along the smooth surface of the third hinge plate 308, and as the slope of the third hinge plate 308 lifts up (as shown in fig. 8), a gap is generated between the extrusion block 302 and the lower lens 103, the extrusion block 302 continues to push the lens 103 to slide until the lens 103 contacts the friction surface of the third sliding plate 312, then the lens 103 pushes the third sliding plate 312 to slide in the fifth sliding groove 314 through the friction surface of the third sliding plate 312, after the third sliding plate 312 slides to the limit position, the extrusion block 302 continues to push the lens 103 to move, at this moment, the lens 103 abuts against the third sliding plate 312, the second hinge plate 307 rotates around the rotating rod 305 under the pushing of the lens 103, and the second hinge plate 307 drives the first hinge plate 306 and the third hinge plate 308 to rotate around the rotating rod 305; because the first sliding plate 309 and the second sliding plate 310 can only move along the moving direction of the extrusion block 302, the first protruding block 315 and the second protruding block 316 respectively drive the first hinge plate 306 and the third hinge plate 308 to approach to the position of the rotating rod 305 along the third sliding groove 317 and the fourth sliding groove 318, at this time, the first sliding plate 309 slides in the first sliding groove 303 along the direction approaching to the rotating rod 305 under the action of the first hinge plate 306, the second sliding plate 310 slides in the direction approaching to the rotating rod 305 along the second sliding groove 304 under the action of the third hinge plate 308, the second sliding plate 310 compresses the first elastic member 311, when the first elastic member 311 is extruded to the limit position, the included angle between the third hinge plate 308 and the second sliding plate 310 is ninety degrees, the thrust of the third sliding plate 312 in the sliding direction of the fifth sliding groove 314 gradually decreases, the third sliding plate 312 slides in the direction away from the rotating rod 305 in the fifth sliding groove 314, when the included angle between the third hinge plate 308 and the second sliding plate 310 is ten degrees, the side of the lens 103 is not sliding again, and the side of the lens 103 is tilted, and the lens 103 is separated from the rest is closed.
Then, the cylinder 504 is started again, so that the cylinder 504 drives the supporting plate 502 to move downwards by a distance equal to the thickness of the lens 103, in the downward movement process of the cylinder 504, the supporting plate 502 is contacted with the first button 505, and the button 505 is pushed, so that the corresponding first electromagnet ring 202 is electrified to generate magnetism, the lower magnetic block 204 is attracted to slide upwards in the vertical groove 207 to be contacted with the first annular groove 205, the magnetic block 204 drives the annular plate 203 to move upwards, and the annular plate 203 drives the fixing plate 301 to move upwards, so that the lens 103 is separated from the lower lens 103.

Then the next pressing block 302 is separated from the limiting box 503, so that the next lens 103 is clamped, and then the air cylinder 504 is started to move downwards once, in the process, the supporting plate 502 is separated from the first button 505, the first electromagnet ring 202 loses magnetism, then the supporting plate 502 pushes the second button 505 again, so that the second electromagnet ring 202 generates magnetism, suction force is generated on the lower magnetic block 204, the next ring plate 203 moves upwards, at the moment, the last ring plate 203 is located at the position of the second ring groove 206, when the next ring plate 203 moves upwards, a downward force is applied to the last ring plate 203 by the deflection assembly between the two ring plates 203, the last ring plate 203 is abutted against the electromagnet ring 202 by the magnetic block 204, and cannot move upwards, and only can rotate along the first ring groove 205, so that the fixing plate 301 drives the lens 103 to deflect by a preset angle, and all fixing plates 301 can drive the lens 103 to rotate, and finally spread out in a fan shape (as shown in fig. 13).
After the electromagnet ring 202 in the second chute 304 is electrified, the ring plate 203 below slides upwards along the vertical groove 207 under the action of the magnetic block 204, the magnetic block 204 finally stays in the vertical groove 207 to attract the electromagnet ring 202, at this time, the rotating rod 201 is rotated, and the rotating rod 201 drives the ring plate 203 below the second annular groove 206 to rotate, so that all the ring plates 203 are driven to rotate, and the detection platform 102 can detect the lens 103 of the non-overlapped part.
When the reset is needed after the detection, the lantern ring 604 is rotated, so that the inside of the loop bar 601 is communicated with the outside through the through hole 605, each ring plate 203 can rotate freely, and finally, the power of the electromagnet ring 202 in the second ring groove 206 is disconnected, and the supporting plate 502 is lifted to the original position.
