Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] Such as Figure 13 As shown, the state schematic diagram of the tearing of the lens mold in the present invention; the lens mold is composed of mold A50, mold B51 and adhesive tape 53 coated on the peripheral surfaces of molds A and B, and 54 in the figure is formed after the adhesive tape is torn. Tape-covered opening.

[0041] Such as figure 1 and figure 2 As shown, the lens mold pouring system includes a frame 1, on which a holding mechanism 2 is arranged, and the holding mechanism fixes the lens mold and drives it to rotate;

[0042]Tear sealing mechanism 3, the tear sealing mechanism is installed on the frame and is located at the side of the holding mechanism, the tear sealing mechanism is used to grab the end of the tape on the surface of the lens mold 5, and then separate the driving tape from the lens mold to form a An opening that is not covered b...

Abstract

The invention belongs to the field of lens production equipment, and particularly relates to a lens mold pouring system. The lens mold pouring system comprises a machine frame, a seal tearing mechanism and a pouring assembly, wherein a retaining mechanism is arranged on the machine frame, and the retaining mechanism fixes a lens mold and drives the lens mold to rotate; the seal tearing mechanism is installed above the seal tearing mechanism and located on the side edge of the retaining mechanism, the seal tearing mechanism is used for grasping the end of an adhesive tape on the surface of thelens mold, and then drives the adhesive tape to separate from the lens mold to form an opening without adhesive tape covering; after the pouring is finished, the seal tearing mechanism is matched withthe retaining mechanism to enable the torn adhesive tape to be re-pasted, and the sealing is completed; and the pouring assembly is connected with the machine frame and located above the retaining mechanism, and the pouring assembly is used for injecting the lens base body into a cavity of the lens mold. The lens mold pouring system changes the way of tearing adhesive tape in the prior art, and improves the production efficiency and quality of the whole pouring system.

Description

technical field [0001] The invention belongs to the field of lens production equipment, in particular to a casting system for lens molds. Background technique [0002] Lens manufacturing is mainly divided into three modules: substrate, hardening, and coating. Among them, the production steps of the substrate are the most and complicated. Filling is to manually inject the raw materials that have been pre-polymerized to a certain viscosity into the assembled mold, and The injection port needs to be sealed to ensure that the quality meets the requirements, but the current manual filling has high technical requirements for workers and is inefficient and has a low pass rate. [0003] The lens mold includes a mold A and a mold B, and a sealing tape wound on the peripheral surfaces of the mold A and the mold B. The sealing tape wraps around the peripheral surface and extends with a fitting part, and the length of the fitting part is about 70 mm. [0004] Chinese invention patent a...
