The first polishing platform 90 and the second polishing platform 100 are exemplary circular and their size is adapted to the polishing container 60. The rotating shaft 110 can drive the first polishing platform 90 and the second polishing platform 100 to rotate and flip.

[0032] See Figure 1 , Figure 2 and Figure 3The lifting module 30 and the tilting lifting combination module 40 are respectively disposed on the first module support platform 70 and the second module support platform 80; the first end and the second end of the rotating shaft 110 are rotatably connected to the lifting module 30 and the tilting lifting combination module 40 respectively; the polishing container 60 is provided with a U-shaped notch 120 for avoiding the rotating shaft; the lifting module 70 and the tilting lifting combination module 80 are used to drive the double-sided polishing platform module 40 to lift and tilt, so that either the first polishing platform 90 or the second polishing platform 100 is housed in the polishing container 60.

[0033] In the polishing equipment of the present invention, during polishing operations, for example, materials can be placed on the first polishing platform 90 first, and then the double-sided polishing platform module 40 can be lifted as a whole by the lifting module 30 and the flipping lifting combination module 40. Then, the first polishing platform 90 can be flipped downward by the flipping lifting combination module 40. Then, the double-sided polishing platform module 40 can be lowered as a whole by the lifting module 30 and the flipping lifting combination module 40 to place the first polishing platform 90 carrying the polishing material into the polishing container 60. Then, polishing can be started. While the material is polishing on the first polishing platform 90, loading and unloading can be carried out simultaneously on the second polishing platform 100, thereby improving the polishing efficiency.

[0034] See Figure 1 and Figure 4 In an optional embodiment of the present invention, a loading / unloading robot 121 is further included. The loading / unloading robot 121 includes a first Y-axis guide rail 130 (slide table module), a second Y-axis guide rail 140 (slide table module), an X-axis guide rail 150 (slide table module), and a Z-axis picking robot 160.

The two ends of the X-axis guide rail 150 are slidably disposed on the first Y-axis guide rail 130 and the second Y-axis guide rail 140. The Z-axis picking robot 160 is slidably disposed on the X-axis guide rail 150. In this embodiment of the present invention, the loading / unloading robot 121 can be used for loading and unloading, saving labor and further improving the working efficiency of the polishing equipment.

The incoming material is placed vertically side by side on the loading rack 240. During polishing, the material on the loading rack 240 can be manually removed and placed on the material picking and positioning component 250. Then, the Z-axis picking robot 170 picks up the material from the picking and positioning component 250 and places it on the polishing platform. The polished material can be directly placed vertically into the unloading rack 260 by the Z-axis picking robot 170. Alternatively, it can be placed on the picking and positioning component 250 first and then manually unloaded.

Each polishing turntable 310 includes a rotary motor 320, a harmonic reducer 330 connected to the rotary motor 320, and a material carrier plate 340 connected to the output shaft of the harmonic reducer 330. In this invention, the polishing of the material on the first polishing platform 90 is achieved by rotating the polishing turntables 310. By providing multiple polishing turntables 310, the polishing material in the polishing container 60 can flow sufficiently, resulting in more thorough and uniform polishing. In an optional embodiment of the present invention, adjacent polishing turntables 310 can be configured to rotate in opposite directions, and a vibration device is provided at the bottom of the polishing container 60 to further promote the flow of the polishing material.

The plurality of guide columns 380 can ensure the stability of the sliding of the lifting plate 390, and the use of a screw motor for driving can ensure the synchronicity of the lifting module 30 and the tilting lifting combination module 40.

[0041] See Figure 9In an optional embodiment of the present invention, the tilting and lifting assembly 40 further includes a tilting drive component disposed on the lifting plate 390. The tilting drive component includes a driven gear 430 and a tilting drive motor 440 with a driving gear.
