Automatic grinding and polishing system of crystal blank

Abstract

An automatic grinding and polishing system for a crystal blank comprises: upper hemisphere grinding stations (11, 12) and polishing station (13) that are arranged around a first rotation rack (2), the first rotation rack (2) being provided with a handpiece (21); lower hemisphere grinding stations (31, 32) and polishing station (33) that are arranged around a second rotation rack (4), the second rotation rack (4) being provided with a handpiece (41); a loading station (6); a butt joint station (5); a discharging station (7); and a transferring mechanism capable of picking up and laying down a fixture, and sequentially transferring the fixture among the loading station (6), the handpiece (21) of the first rotation rack (2), the butt joint station (5), the handpiece (41) of the second rotation rack (4), and the discharging station (7). A grinding and polishing system is further provided, where the loading station and the discharging station are combined into a loading-discharging station. The present invention not only implements the automatic grinding and polishing processing and ensures the quality of the grinding and polishing processing, but also fully utilizes the advantages of the existing machine type, hence simplifying the complexity of mechanism actions, reducing the machine volume, and being easy to manufacture, transport, and maintain.

Description

technical field [0001] The invention relates to the field of grinding and polishing of crystal products, in particular to an automatic grinding and polishing system for crystal blanks for automatic grinding and polishing of crystal blanks. Background technique [0002] The existing multi-station crystal bevel grinding and polishing machine adopts a plurality of machine heads fixed with rhinestone fixtures to rotate for multi-station processing. For example, the patent document with publication number CN201179615Y discloses an automatic loading and unloading rhinestone bevel grinding and polishing The machine includes a frame. Two rotating frames are arranged side by side on the frame, and one head is set on each of the four sides of the rotating frame to form seven stations, which are the feeding station, the front hemisphere rough grinding station, and the front hemisphere polishing station. Position, docking station, rear hemisphere rough grinding station, rear hemisphere ...

AI Technical Summary

Problems solved by technology

During the actual implementation of this technical solution, the inventor found the following problems: First, at the docking station, the two docking fixtures are respectively located on the two rotating frames, which requires high manufacturing precision and is difficult Ensure the docking accuracy; secondly, the machine is large in size, which is difficult to manufacture and transport; thirdly, the space for the docking station, loading station, and unloading station is limited, and the complex structure design and cumbersome actions affect the processing efficiency

However, all the stations of the whole machine are arranged around a cantilever turntable (equivalent to a rotating frame), the machine is huge in size, difficult to manufacture and transport, the space of each station is small, the mechanism layout is difficult, and it is inconvenient for equipment installation and maintenance; its grinding and polishing The station uses a manipulator to transfer the fixture, which also has problems such as difficult manufacturing and high manufacturing precision requirements.
