Description

Technical Field

[0001] The utility model belongs to the field of grinding and polishing, and in particular relates to a polishing device. Background Art

[0002] The rapid development of the 3C industry has led to the development of the glass industry. Smart devices are widely used in display screens, and the display screens are mostly made of glass sheets. Taking smartphones as an example, the front and back covers of mainstream high-end mobile phones are mostly made of glass. During the processing of mobile phone covers, existing grinding and polishing machines still need to stop and operate during the loading and unloading and replacement of consumables during the processing process, and rely on manual replacement. As a result, existing grinding and polishing machines have the following problems:

[0003] First, due to the lack of manual loading, the loading frequency is high, and since the glass after unloading and collection still needs to be manually organized and transported, it not only reduces the processing efficiency, but also leads to high labor costs and high labor intensity. Secondly, manual operation is subjective, and the operating methods and strengths of different operators may vary, thus affecting the processing quality and consistency of the product. Finally, manual replacement of consumables takes a long time and requires downtime, which not only reduces production efficiency, but also may cause the consumables to not be clamped.
