Description

Technical Field

[0001] This utility model relates to the technical field of workpiece polishing equipment, and more specifically, to a freely positioning rotary polishing device. Background Technology

[0002] With the rapid development of digital electronic products, glass is being used more and more widely in 3C electronic products such as mobile phones. As for the back cover glass of mobile phones, it takes multiple equipment and multiple processes to complete a complete and qualified back cover glass. As an important structural component of mobile phones, the precision and appearance quality of the back cover glass determine the appearance of the mobile phone.

[0003] Currently, the traditional polishing process for mobile phone back cover glass involves polishing the perimeter first, then the camera hole, and finally the main surface. Polishing the camera hole requires X-axis and Y-axis interpolation to achieve circular polishing. However, as the structure of current mobile phone back covers becomes increasingly complex, with more and more cameras, traditional glass polishing equipment, limited by factors such as processing stroke, cannot complete the polishing of different locations and areas with a single machine. This results in existing polishing equipment being unable to meet the polishing requirements of mobile phone back cover glass.
