Description

Technical Field

[0001] The invention relates to the technical field of injection molded lens product production, in particular to an ultrasonic water cut anti-scratch component for injection molded lens product production. Background Art

[0002] The sprue is the connecting material between the parts of the injection molded product during the injection molding process. It is generally the inlet or outlet for the flow of the injection molding material after hot melting. After the injection molding of the injection molded lens is completed, the sprue needs to be cut off. Currently, the common sprue cutting methods include manual cutting, laser cutting and ultrasonic cutting. Manual cutting has low efficiency and low product smoothness. Laser cutting is prone to smoke and uneven incision. Ultrasonic sprue cutting uses ultrasonic high-frequency vibration to quickly cut off excess material. The Chinese patent with application number 202121136748.6 discloses "an ultrasonic sprue cutting device, including: a vibration seat, a support Support platform, ultrasonic vibrator, the vibration seat is installed on the support platform, the ultrasonic vibrator is set in the vibration seat, a receiving groove is opened on one side of the support platform, and a plurality of through holes are opened on the support platform, each through hole is connected to the receiving groove. When performing the water outlet removal operation of a smaller product, hold the product including the frame close to the vibration seat, so that the water outlet contacts the surface of the vibration seat, and the vibration of the vibration seat is driven by the vibration generated by the ultrasonic vibrator. At this time, the amplitude generated by the ultrasonic wave enables the vibration seat to achieve the effect of removing the water outlet, and the product after the water outlet is removed falls from the through hole into the receiving groove, thereby improving the efficiency of water outlet removal of smaller products.

[0003] This comparative document only solves the problem of low efficiency of manual water outlet cutting. However, when ultrasonic wave is used to cut the water outlet of injection-molded lens products, the injection-molded lens products are easy to fall, resulting in scratches on the surface of the injection-molded lens products. In addition, after the water outlet of the injection-molded lens products is cut off by ultrasonic wave, the injection-molded lens products scattered in the hopper need to be manually sorted out, and the injection-molded lens products need to be turned over for subsequent production.

[0035] Working principle: When the present invention is used, the ultrasonic water-cutting device for cutting the injection-molded lens product is placed under the ultrasonic water-cutting device, the injection-molded lens to be cut is placed in the material tank 405, the ultrasonic water-cutting device is started, and the injection-molded lens placed on the lifting platform 404 is cut off from the water-cutting device, so that the injection-molded lens enters the blanking barrel 401. After the ultrasonic water-cutting device is raised, the dual-axis motor 3 is started, and the dual-axis motor 3 drives the worm 408 to rotate through the first transmission belt 409, and the worm 408 drives the worm wheel 406 to rotate through the worm wheel 406. 6 drives the lifting threaded cylinder 402 to rotate, so that the lifting platform 404 moves downward. At this time, the injection molded lens is inside the top of the blanking cylinder 401, and the cut nozzle is at the top of the nozzle support plate 403, so that the nozzle and the injection molded lens are separated without contact, so as to avoid the nozzle from scratching the injection molded lens and also avoid the injection molded lens from falling from a high place and causing scratches. When the dual-axis motor 3 is started, the dual-axis motor 3 drives the transmission gear 507 to rotate through the second transmission belt 508, and drives the transmission toothed belt 509 to rotate through the transmission gear 507, so as to drive the moving gear 510 to rotate on the transmission toothed belt 5 09, when the moving gear 510 moves, it drives the slider 502 and the moving frame 503 to move through the support shaft 511, so that when the lifting platform 404 descends, the moving frame 503 moves to the top of the lifting platform 404, and when the suction cup 506 follows the moving frame 503 to move to the top of the injection-molded lens, the double-axis motor 3 is controlled to stop rotating, and then the negative pressure vacuum pump 504 is started. The negative pressure vacuum pump 504 sucks up the injection-molded lens from the top of the blanking barrel 401 through the air pipe 505 and the suction cup 506, and then the double-axis motor 3 is controlled to start to reverse. At this time The lifting platform 404 rises, and the moving frame 503 moves toward the top of the collecting barrel 513 with the injection molded lens sucked up by the suction cup 506. When it moves to the top of the collecting barrel 513, the negative pressure vacuum pump 504 is controlled to be closed. At this time, the injection molded lens enters the collecting barrel 513. Under the action of gravity of the injection molded lens, the injection molded lens presses the top plate 515 into the collecting barrel 513. At this time, the spring 514 is compressed. When entering the subsequent production link, after taking out the top injection molded lens, the injection molded lens below is ejected to the top of the collecting barrel 513 under the elastic force of the spring 514.
