Description

TECHNICAL FIELD

[0001] The utility model relates to the field of car room lens production, especially to a lens unmounting device. BACKGROUND

[0002] With the continuous improvement of people's quality of life, the demand for glasses is also increasing, and people's demand for personalized customized car room lenses is also increasing.

[0003] After the car room lens is finished, it needs to be taken off from the small iron and then processed. Because the lens itself has no boss, in order to facilitate clamping during processing, low-temperature alloy is usually used to combine the lens and the small iron into a whole (hereinafter referred to as "lens assembly"), and then the small iron is clamped for processing. After processing is completed, the lens and the small iron are separated to take off the lens.

[0004] The conventional lens taking-off method is generally divided into two types. One is to soak the lens on the upper disc in hot water, and after the alloy is melted, the lens and the small iron are separated to complete the lens unmounting. During the hot water unmounting process, a layer of thick alloy will be left on the surface of the lens film, which needs to be manually scraped off, which is time-consuming and laborious. The other is to knock the lens and the small iron as a whole on the tool to separate the lens and the small iron. Since the lens material is brittle, knocking the lens may cause the lens to break, resulting in a decrease in the yield rate.

[0005] For the above related technology, the inventor believes that a lens unmounting device that can automatically separate the lens and the small iron conveniently, safely and efficiently is needed, and the yield rate of the lens is improved. UTILITY MODEL CONTENTS

7. The lens lower plate device according to claim 1, characterized in that: The lower tray box is equipped with a positioning assembly for holding the lens. The positioning assembly includes clamping plates on both radial sides of the lens. A fixing plate is provided at the end of the clamping plate away from the lens. A mating plate is fixed on the side of the clamping plates that are close to each other. The two ends of the fixing plate in the length direction are rotatably connected to the mating plate. A telescopic cylinder is installed on the outer wall of the lower plate box via a bracket. The piston rod of the telescopic cylinder is connected to a telescopic rod. The end of the telescopic rod away from the telescopic cylinder passes through a fixed plate and is slidably connected to the fixed plate. A receiving groove is provided on the part of the telescopic rod near the mating plate. The receiving groove is located on the top and bottom of the telescopic rod. The two mating plates corresponding to the two clamping plates are staggered to match the position of the corresponding receiving groove. A mating rod extends from the mating plate. The end of the mating rod away from the mating plate is movably set in the corresponding receiving groove. When the telescopic rod moves toward the lens, the clamp opens; when the telescopic rod moves away from the lens, the clamp closes.

8. The lens lower plate device according to claim 7, characterized in that: Each fixed plate has a rotating seat fixed on the side away from the lens. The rotating seat is coaxially connected to a rotating tube at the end away from the lens. The rotating tube is rotatably connected to the side wall of the lower plate box through a bearing. The telescopic rod passes through the rotating tube and is slidably connected to the rotating tube. A rotating motor is mounted on the outer wall of the lower tank via bracket two. A drive gear is coaxially connected to the output shaft of the rotating motor, and a driven gear is coaxially connected to each rotating tube. Two driven gears mesh with each other, and the drive gear meshes with one of the driven gears.

9. The lens lower plate device according to claim 1, characterized in that: The clamping assembly includes a support plate and clamping blocks.
