Description

Technical Field

[0001] The invention relates to the technical field of workpiece polishing equipment, and in particular to a multi-station continuous polishing equipment. Background Art

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

[0003] At present, the traditional process for polishing the back cover glass of mobile phones is: first polish the four sides, then polish the camera hole, and finally polish the large surface. When polishing the camera hole, X-axis and Y-axis interpolation circles are generally used to achieve it, and different areas require different polishing processes. However, as the existing mobile phone back cover structure design becomes increasingly complex, the number of cameras is increasing, and the polishing accuracy requirements are also getting higher and higher. Traditional glass polishing equipment is usually unable to integrate different polishing processes. When performing polishing operations, the equipment can generally only perform one polishing process. When facing the polishing needs of multi-process products, it is generally divided into multiple devices for work, or on a single device, different polishing parts are disassembled and assembled to achieve the multi-process polishing needs of the product. However, using multiple devices for processing will undoubtedly increase the cost, and only using a single device for operation will result in low polishing efficiency, which results in the inability of existing polishing equipment to meet the polishing needs of mobile phone back cover glass.

Each station rotating mechanism 3 is sequentially installed with the X-axis moving mechanism 4, the Y-axis moving mechanism 5, the waterproof shielding mechanism 6 and the workpiece fixing mechanism 7 from bottom to top. The polishing workpiece is fixedly installed on the workpiece fixing mechanism 7. The X-axis moving mechanism 4 and the Y-axis moving mechanism 5 are respectively used to displace the polishing workpiece in the X-axis and Y-axis directions, thereby increasing the workpiece position. The polishing operation stroke of large workpieces, combined with the fixed-axis rotation function of the indexing disc 2 and the station rotating mechanism 3, enables the installation components to realize self-rotation at any position within the stroke range; secondly, the support frame 8 is installed on the polishing machine box 1, and the polishing mechanism 9 is arranged above the workpiece fixing mechanism 7 through the support frame 8. The polishing mechanism 9 is provided with multiple pieces, and the multiple polishing mechanisms 9 are evenly spaced along the axial direction of the support frame 8. It is used to polish the polishing workpiece installed on the workpiece fixing mechanism 7. The polishing mechanism 9 is composed of the Z-axis moving mechanism 9-1, The moving plate 9-2, the polishing drive mechanism 9-3 and the polishing grinding head 9-4 are composed. The polishing drive mechanism 9-3 is vertically installed on the Z-axis moving mechanism 9-1 through the moving plate 9-2. The polishing drive mechanism 9-3 is driven by the Z-axis moving mechanism 9-1 to move up and down in the Z-axis direction to perform polishing operations. The polishing grinding head 9-4 is installed on the polishing drive mechanism 9-3. Each polishing drive mechanism 9-3 is equipped with a polishing grinding head 9-4 for different polishing processes. Combined with the fixed-axis rotation function of the indexing disk 2, polishing operations for different processes can be achieved.
