Description

Technical Field

[0001] This invention relates to the field of lens manufacturing, and particularly to a combined production equipment for polymer defocused PC lenses. Background Technology

[0002] Eyeglasses play a vital role as the primary vision aid. With changing eye habits and increased awareness of eye health, "early onset, accelerated progression, and severe myopia" have become the most prominent problems facing adolescents' eye health, leading to a growing demand for myopia prevention and control. For adolescents whose vision is still developing, the quality of eyeglasses can influence the progression of myopia.

[0003] Polymer defocusing PC lenses are manufactured by precisely carving aspherical pits in a mold during the production process. These aspherical pits are then arranged in concentric circles or honeycomb patterns, creating regularly arranged aspherical microlenses on the surface of the injection-molded Bayer-PC material. Light passes through these arranged aspherical microlenses, achieving multi-point defocus and forming a signal zone in front of the retina to slow down the growth of the eye axis, thus controlling and slowing the progression of myopia.

[0004] The manufacturing process of multi-point defocused PC lenses is complex, and each production step requires cumbersome equipment. Existing equipment suffers from low equipment interoperability and low production efficiency.

[0005] There is an urgent need for a combined production equipment for polymer defocused PC lenses that can meet the following technical problems: in-mold coating of lenses, stable loading and unloading from the mold, smooth transfer of lenses, clean and dust-free lens surfaces, uniform coating and hardening of lenses, and balanced drying.

[0081] The working principle of the combined production equipment for polymer defocused PC lenses in this embodiment is as follows:

[0082] The operator presses the operation button, and the coating sliding fixture moves towards the pneumatic explosion-proof door, which then rises. The operator places the film on top of the coating sliding fixture and presses the operation button again. The pneumatic explosion-proof door descends, and the coating sliding fixture moves into the equipment. The flip drive cylinder drives the flip assembly (flip top plate, flip bottom plate, guide column) to make the suction cups face downwards. The linear module descends, causing the suction cups to adhere to the lens film, and the vacuum pressure gauge checks the adhesion level. After the linear module rises, the flip drive cylinder flips the suction cups to the side. The ejection cylinder pushes the flip top plate out of the equipment, and the film is removed by the high-speed in-mold transfer equipment.

[0083] The pick-and-place fixture assembly is moved out of the equipment at high speed under the drive of the transfer pneumatic slide; it is positioned at the film-taking position by the action of the pin positioning cylinder; the film-taking plate extends under the action of the film-applying cylinder to take off the film supplied by the film-applying mechanism, and then retracts; the pin cylinder is released, and the pick-and-place fixture assembly continues to move into the injection mold; the lens clamping mechanism is pushed forward under the action of the pull-out cylinder and the demolding cylinder, and the lens clamping mechanism clamps the defocused PC lens, the demolding cylinder separates the lens from the mold, and then the pull-out cylinder retracts; the pick-and-place fixture assembly is moved into the processing and manufacturing equipment under the drive of the transfer pneumatic slide.

[0084] The insert storage bin releases inserts onto the insert conveyor belt, which moves forward; the gripper cylinder removes the formed lens from the high-speed in-mold transfer device; due to the layout of the injection molding production equipment, one side of the gripper cylinder rotates the lens to the other side; then the stacking and flipping cylinder embeds the snap-on shank of the formed lens into the insert below. One insert can hold 10 sets of lenses, after which the insert continues to move forward; the flipping and transfer mechanism assembly can, under the drive of the screw, alternately grip the inserts on both sides and flip them 180°; the immersion lifting robot assembly's immersion rotary cylinder can flip the immersion insert gripper to the left and right directions, and the immersion insert gripper takes the insert carried by the flipping and transfer mechanism assembly, and under the drive of the immersion linear module, the defocused PC lens is immersed in the coating solution;

[0085] Driven by the transverse linear module, the transfer robot can grip the soaked lens fixing strips from both sides; the oven door of the first-stage oven lowers and opens, the longitudinal robot moves the lens to the first-stage oven, and the oven door rises; the oven door of the second-stage oven lowers and opens, the longitudinal robot moves the lens to the second-stage oven, and the oven door rises; the oven door of the third-stage oven lowers and opens, the longitudinal robot moves the lens to the third-stage oven, and the oven door rises; after the defocused PC lens is dried, the longitudinal robot places the lens on the cooling rack.

[0086] The combined production equipment for polymer defocused PC lenses in this embodiment can meet the requirements of in-mold film application, stable loading and unloading from the mold, smooth lens transfer, clean and dust-free lens surface, uniform coating and hardening of the lens, and balanced drying.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
