[0016] 1. The automatic lens removal device for separating lenses from molds, when working, first automatically places a row of upper mold bodies containing lenses on the upper mold support plate, starts the extrusion drive motor, drives the moving rack to move forward through the second support plate, thereby extruding the upper mold body, making it cooperate with the fixed rack, and after the fixed rack and the moving rack extrude and deform the upper mold body to a certain extent, starts the translation drive motor, drives the first support plate to move, thereby drives the extrusion drive motor and the moving rack to translate together, and the upper mold body will rotate between the fixed rack and the moving rack. After rotating one circle, the translation drive motor drives the moving rack to return to the initial position, and then starts the suction cup lifting drive cylinder to drive it The movable suction cup rotation driving cylinder and the lens taking suction cup descend together, and the lens taking suction cup absorbs the contact lens on the curved surface of the upper mold body. Then, after the suction cup lifting driving cylinder rises to its position, the suction cup rotation driving cylinder drives the lens taking suction cup to rotate, so that the notch of the contact lens faces upward, which is convenient for the subsequent automatic material taking mechanism to take and place the lens. After the lens taking suction cup absorbs the contact lens, the upper mold driving cylinder drives the upper mold support plate to retract, and at the same time, the extrusion driving motor drives the moving rack to retract. At this time, the upper mold body with the lens taken out will fall from the upper mold support plate into the groove, and then fall into the upper mold funnel, so that it flows out from the leak nozzle at the bottom of the upper mold funnel, and then a material box connected to the upper mold body is placed below the upper mold funnel to collect the waste.
