9. The optical lens piece detection tool of claim 8, wherein: the measuring scale (35) is composed of a graduated scale and two cursors, and the two cursors slide outside the graduated scale.
10. A positioning method of an optical lens detection jig is characterized in that: the positioning method comprises the following steps:
the method comprises the following steps: placing the optical lens between two V-shaped clamping plates (23) between a first clamping block (18) and a second clamping block (19), and then rotating a screw rod (20) to enable the first clamping block (18) and the second clamping block (19) to slide through a second T-shaped groove (17), so that the optical lens is clamped and fixed;
step two: starting a laser (4) and a light transmittance detector (5) to work, wherein light of the laser (4) passes through an optical lens and a through hole (6) to irradiate the light transmittance detector (5), and the light transmittance detector (5) detects light transmittance;
step three: the second sleeve ring (31) slides outside the sliding rod (30), so that the measuring scale (35) is perpendicular to the upper position of the optical lens, then the measuring scale (35) moves in the inner vertical direction of the sleeve rod (33) through the extension rod (34), a vernier of the measuring scale (35) moves to contact with two surfaces of the optical lens, so that the thickness of the optical lens is detected, and after the detection is finished, the sliding rod (30) is turned over outside the connecting rod (28) through the first sleeve ring (29) so as not to shield the subsequent operation;
step four: the LED lamp (25) is turned on to work, then the optical lens is rotated to an angle keeping the same ray with the LED lamp (25) through the rotating shaft (22), and meanwhile, the LED lamp (25) can also be rotated through the support (24) to adjust the angle, so that the light of the LED lamp (25) fully irradiates the optical lens, and at the moment, whether the surface of the optical lens has defects such as scratches and bubbles can be observed;
step five: the optical lens is taken down and placed between the first clamping plate (10) and the second clamping plate (11), then the first screw rod (12) is rotated, the first screw rod (12) drives the first clamping plate (10) and the second clamping plate (11) to move in the opposite direction, the optical lens is clamped and fixed, after clamping is completed, the second screw rod (13) is rotated, the second screw rod (13) drives the pressure sensor (14) to vertically move downwards until the pressure sensor (14) is pressed on the upper portion of the optical lens, whether the optical lens is broken or not and whether the optical lens is cracked or not is observed under the condition of continuous pressurization, and then the maximum pressure bearing capacity of the optical lens can be detected.
