Description

Technical Field

[0001] This utility model relates to the technical field of workpiece polishing equipment, and more specifically, to a multi-station continuous polishing equipment. 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 is as follows: first polish the perimeter, then the camera hole, and finally the main surface. When polishing the camera hole, X-axis and Y-axis interpolation is generally used to achieve circular polishing, with different polishing processes required for different areas. However, due to the increasingly complex structural designs of current mobile phone back covers, the number of cameras is increasing, and the polishing precision requirements are also rising. Traditional glass polishing equipment typically cannot integrate different polishing processes; it can usually only perform one polishing process at a time. When dealing with the polishing needs of multi-process products, multiple machines are usually used to divide the work, or different polishing components are disassembled and assembled on a single machine to meet the multi-process polishing requirements. However, using multiple machines undoubtedly increases costs, while using only a single machine results in low polishing efficiency. This means that existing polishing equipment cannot meet the polishing requirements of mobile phone back cover glass.

[0004] Therefore, how to provide a multi-station continuous polishing equipment that can integrate different polishing processes, meet the polishing needs of different technologies, and improve the processing efficiency of the equipment has become a technical problem that urgently needs to be solved by those skilled in the art.

[0076] The technical solution of this utility model will be specifically described below with reference to the embodiments:

[0077] Specifically, in an embodiment of this utility model, the Z-axis moving mechanism 9-1 includes: a first mounting base 9-1-1; a mounting joint 9-1-2 disposed on the bottom surface of the first mounting base 9-1-1 and connected to the support frame 8; a first linear guide rail 9-1-3 symmetrically disposed on the first mounting base 9-1-1; a first moving slider 9-1-4 disposed on the first linear guide rail 9-1-3 and connected to the moving plate 9-2; a Z-axis protective cover 9-1-5 disposed on the top surface of the first mounting base 9-1-1; a telescopic protective cover 9-1-6 disposed on the side wall of the first mounting base 9-1-1; and a first driving mechanism 9-1-7 disposed inside the first mounting base 9-1-1 for driving the moving plate 9-2.

[0078] like Figure 3 , 4 As shown, the Z-axis moving mechanism 9-1 is used to drive the polishing drive mechanism 9-3 and the polishing head 9-4 to move up and down in the Z-axis direction. In this embodiment of the utility model, the Z-axis moving mechanism 9-1 is composed of the first mounting base 9-1-1, the first linear guide rail 9-1-3, the first moving slider 9-1-4, and the first drive mechanism 9-1-7.

[0080] In this embodiment of the invention, the first driving mechanism 9-1-7 drives the movable plate 9-2, thereby causing the rotary polishing mechanism 9 and the polishing head 9-4 to move up and down.

The third linear guide rail and the third moving slider 5-3 combine to form a Y-axis guiding mechanism. The waterproof shielding mechanism 6 is mounted on the third moving slider 5-3. Driven by the third driving mechanism, the waterproof shielding mechanism 6 can move on the third linear guide rail 5-2, thereby driving the workpiece fixing mechanism 7 mounted on the waterproof shielding mechanism 6 to move back and forth in the Y-axis direction.

A servo motor provides rotational power, enabling the third transmission screw to rotate along a fixed axis between its fixed end and its support end. A third transmission nut seat is fitted onto the third transmission screw and is fixedly connected to the waterproof shielding mechanism 6. Driven by the third servo motor, the third transmission nut seat can move back and forth on the third transmission screw, thereby driving the waterproof shielding mechanism 6 mounted on the third transmission nut seat to move, and enabling the workpiece fixing mechanism 7 mounted on the waterproof shielding mechanism 6 to move back and forth in the Y-axis direction.

The X-axis moving mechanism 4 and the Y-axis moving mechanism 5 are respectively used to displace the polished workpiece in the X-axis and Y-axis directions. The polishing stroke of the workpiece is increased, and combined with the fixed-axis rotation function of the indexing disk 2 and the station rotation mechanism 3, the mounting component can rotate at any position within the stroke range; secondly, the support frame 8 is installed on the polishing machine housing 1, and the polishing mechanism 9 is set above the workpiece fixing mechanism 7 through the support frame 8.

The polishing drive mechanism 9-3 is vertically mounted on the Z-axis moving mechanism 9-1 via the movable plate 9-2. The Z-axis moving mechanism 9-1 drives the polishing drive mechanism 9-3 to move up and down in the Z-axis direction to perform polishing operations. The polishing head 9-4 is mounted on the polishing drive mechanism 9-3. Each polishing drive mechanism 9-3 is equipped with a polishing head 9-4 for different polishing processes. Combined with the fixed-axis rotation function of the indexing disk 2, polishing operations of different processes can be realized. Therefore, the technical solution provided by this utility model, compared with the prior art, can integrate different polishing processes, meet the polishing requirements of different processes, and improve the processing efficiency of the equipment.
