One of the two groups of material racks is used for feeding and the other is used for discharging and collecting materials.

[0025] When the lens processing and production glue injection equipment is in use, the lenses to be injected with glue are evenly arranged in the material rack on one side. Subsequently, the equipment is started. In the initial position of the equipment, one of the two sets of material taking seats is located on one side of the material rack with the lenses to be injected with glue, and the other set is located in the middle directly in front of the vertical plate. When taking materials, the driving motor drives the driving screw rod to push the baffle forward, pushing the front lens into the through hole. Then, the material taking cylinder on the material taking seat in front of the through hole drives the material taking suction cup to extend, and the material taking suction cup generates vacuum to adsorb the lens and retracts it into the arc groove on the inner side of the material taking seat. Subsequently, the transposition cylinder extends, pushing the empty material taking seat to the front side of the other set of material racks. At this time, the material taking seat after taking materials moves to the middle directly in front of the vertical plate, and then the lifting rod drives the material taking seat to be lifted to the position of the clamping and rotating mechanism. The clamping cylinder drives the clamping wheels on the opposite side of the connecting seat to clamp the lens. Subsequently, the material taking suction cup releases the material taking seat and descends, and the transposition cylinder retracts to drive the loading and unloading mechanism to reset;

[0026] Before glue injection, the telescopic rod on the rear side of the vertical plate drives the front negative pressure fixing suction cup to adsorb and fix the clamped lens. Then, the tilting cylinder drives the tilting slide plate to extend forward, and the soft glue head arranged at the front end sticks the end of the adhesive tape to the side edge of the lens. Subsequently, the rotating motor rotates to drive the lens to rotate, causing the adhesive tape to wind around the side edge of the lens for one circle. When it is almost full around the side edge, it stops, leaving a small gap. At this time, the glue injection mechanism is started. The electric rod drives the glue injection head to descend while the glue pumping pump extracts glue and injects it through the small gap. After filling, the glue injection head retracts, and the rotating motor continues to rotate to completely close the small gap. The cutting cylinder is started to drive the cutting knife to extend forward to cut the adhesive tape, completing the glue injection processing;

[0027] After the loading and unloading mechanism resets and during the glue injection processing, the material rack with the lenses to be injected with glue continues to push materials, and the material taking seat on this side performs the material taking operation. Then, after the glue injection is completed, the negative pressure fixing suction cup behind the lens releases the lens and retracts. The lifting rod drives the other set of empty material taking seats to rise to the position of the lens after glue injection. The clamping cylinders on both sides retract to release the lens, and at the same time, the material taking cylinder of the material taking seat adsorbs the lens after glue injection and descends. The transposition cylinder extends to drive the two sets of material taking seats to switch positions. The set of material taking seats fixed with the lens after glue injection moves to the other set of empty material racks and sends the lens after glue injection to the material rack for temporary storage; the material taking seat fixed with the lens to be injected with glue moves to the middle directly in front of the vertical plate to perform the aforementioned loading operation and then resets. In this way, the automated glue injection processing is realized in a cycle.
