Description

Technical Field

[0001] This utility model relates to the field of progressive multifocal lens processing technology, specifically to progressive multifocal lens forming equipment. Background Technology

[0002] Progressive multifocal lenses are eyeglasses that correct vision at near, intermediate, and far distances without requiring lens changes. They provide a continuous visual experience by gradually changing the lens power, allowing for a natural transition in vision across different distances. They are particularly suitable for people with presbyopia or mild astigmatism who require multifocal correction. Currently, progressive multifocal lenses require grinding to different sizes before leaving the factory. The molding equipment used for progressive multifocal lenses typically employs a pushing device to advance and shape the lens according to the factory requirements. During this pushing process, pushing in too much or too little can easily cause inaccuracies in the initial circumference size of the progressive multifocal lens, thus reducing the effectiveness of the molding equipment and affecting its molding efficiency.

[0003] Therefore, it is necessary to develop progressive multifocal lens forming equipment. Utility Model Content

Then, a cylinder lowers the rotating seat B, aligning it with the rotating seat A, thus fixing the progressive multifocal lens after positioning. During this process, the circumference of the progressive multifocal lens compresses the grinding shafts on motors B at both ends, causing the springs to contract and deform. Adjustments are made according to the scale based on site requirements. After positioning the limiting seat, rotate the tightening screw to fix it, so that motor B drives the grinding shaft to grind and shape the progressive multifocal lens. During the grinding and shaping process, the progressive multifocal lens continuously shrinks until it contacts the limiting seat.

[0025] Working principle: When using this utility model, the guide column 201 on the movable frame 2 is slidably connected to the top of the operating box 1, and the output end of the cylinder 101 on the operating box 1 is fixedly connected to the top of the movable frame 2, so that the cylinder 101 can drive and control the movable frame 2 to perform height adjustment. The movable frame 2 and the operating box 1 are rotatably connected by setting the rotating base B202 and the rotating base A102, and anti-slip rings 103 are set at the joint of the rotating base B202 and the rotating base A102. According to the requirements of machining standards, a laser rangefinder is required. For the progressive multifocal lens that needs to be ground and shaped, the rangefinder is positioned at the top of the rotating base A102. The cylinder 101 lowers the rotating base B202 to connect with the rotating base A102. 02. This allows for the installation and fixation of the progressive multifocal lens. By engaging the gear B205 at the output end of the motor A204 on the moving frame 2 with the gear A203 on the rotating base B202, the installed progressive multifocal lens can be rotated. Two sets of limiting seats 305 are slidably connected to the guide groove 301 on the mounting base 3, allowing the limiting seats 305 to move horizontally left or right on the mounting base 3. A tightening screw 307 is connected internally to the pointer plate 306 on the top of the limiting seat 305, allowing the limiting seat 305 to be adjusted as needed. Finally, rotating the tightening screw 307 presses it firmly against the surface of the mounting base 3, thus achieving the desired fixation. The seat 305 is fixed in place, and the contact end of the tightening screw 307 can be fitted with an anti-slip sleeve to improve the anti-slip effect. The guide seat 401 on the mounting bracket 4 is slidably connected to the guide groove 301 on the mounting base 3, and the movable seat 402 on the guide seat 401 is slidably set on the outer wall of the limiting post 302.

During this process, the circumference of the progressive multifocal lens will squeeze the motors B403 at both ends. The grinding shaft 404 on the upper part of the spring 303 contracts and deforms. After adjusting the position of the limit seat 305 according to the scale according to the needs of the site, the top screw 307 is rotated to fix it. The motor B403 drives the grinding shaft 404 to grind and shape the progressive multifocal lens. During the grinding and shaping process, the progressive multifocal lens continuously shrinks until it contacts the limit seat 305. This achieves the limit treatment during the grinding and shaping of the progressive multifocal lens, and avoids the situation where too much or too little advancement during the grinding and shaping process affects the final quality. This effectively improves the use effect of the progressive multifocal lens forming equipment and also effectively improves the forming efficiency of the progressive multifocal lens forming equipment.
