Description

Technical Field

[0001] This utility model belongs to the technical field of optical glass processing equipment, and specifically relates to an optical glass polishing machine. Background Technology

[0002] Polishing is a key process in the processing of optical glass to ensure its optical performance. Polished glass surfaces are required to have extremely high smoothness and flatness to meet the requirements of optical systems for core indicators such as light transmittance and imaging quality.

[0003] Existing optical glass polishing equipment has several limitations in practical applications: Firstly, traditional polishing machines mostly use a single-sided polishing mode, requiring manual flipping of the glass after polishing one side before processing the other side. This is not only cumbersome but also prone to positioning deviations due to secondary clamping, affecting polishing accuracy. Secondly, glass requires stable pressure during polishing, but the clamping mechanisms of existing equipment often struggle to achieve uniform and controllable pressure control at the glass edges, easily leading to uneven polished surfaces due to uneven pressure. Furthermore, if glass debris and polishing agent residue generated during polishing are not removed promptly, they will adhere to the polishing pad or glass surface, causing secondary scratches, severely affecting polishing quality, and increasing subsequent cleaning and rework costs.

[0004] Therefore, there is an urgent need for a polishing equipment that can achieve efficient double-sided polishing, ensure stable pressure, and has an automatic slag removal function, in order to solve the problems of low efficiency, poor precision, and unstable quality in the existing technology.

A limiting card slot is opened on the inner surface of the iron seat. And the limiting card strip is stuck inside the limiting card slot. A positioning groove is opened on the surface of the limiting card strip. A magnet block is bonded in the positioning groove. The magnet block is magnetically fixed to the iron seat by magnetic force.

[0017] Preferably, the pressure limiting part includes a downward - pressing electric push rod fixed to the upper part of the push frame. A lower pressing plate is fixed to the telescopic end of the downward - pressing electric push rod. And the lower pressing plate is located at the connection between the chuck and the optical glass.

[0018] Preferably, the debris removal part includes a slag discharge pipe fixed to the lower surface of the upper part of the polishing frame. An exhaust pipe is welded to the side surface of the slag discharge pipe. A first expansion joint is welded at the connection between the exhaust pipe and the slag discharge pipe. A second expansion joint is arranged in the middle of the slag discharge pipe. Exhaust blowers are installed in both the first expansion joint and the second expansion joint.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. Improve the polishing efficiency and achieve double - sided integrated processing: Through the coordinated cooperation of the lifting part and the rotating part, the clamping part can accurately lift the optical glass to the surface of the polishing disc and rotate itself under the drive of the rotating part.配合抛光盘的转动,能够一次性完成玻璃两面的抛光作业,无需人工翻转,大幅缩短了加工周期,提升了生产效率。

[0021] 2. Ensure the stability of the polishing pressure and improve the processing accuracy: The accurate pressure limiting of the pressure limiting part on the edge of the optical glass can ensure that the glass maintains a uniform and constant contact pressure with the surface of the polishing disc during the polishing process, effectively avoiding the flatness deviation of the polishing surface caused by pressure fluctuations, significantly improving the polishing accuracy of the optical glass, and meeting the processing requirements of high - precision optical components.

[0022] 3. Reduce surface damage and improve product quality: The slag remover can remove debris and residue generated during the polishing process in real time, preventing them from forming friction particles between the polishing pad and the glass surface. This avoids secondary scratches from the source, ensures the smoothness of the glass surface after polishing, and reduces the product scrap rate.

[0023] 4. Enhanced operational stability and reduced human intervention: The linkage design of the clamping, lifting and rotating components realizes the automated operation of glass clamping, lifting and rotating, reducing the frequency of human contact with the glass. This not only reduces human error, but also avoids the risk of glass breakage due to improper human operation, thus improving the stability and reliability of equipment operation.
