[0021] Furthermore, at least two buffers are provided on the flipping mechanism, and are respectively located on the upper and lower sides of the moving direction of the rotating substrate, so as to achieve buffering during the up and down movement and avoid collision.

[0022] Furthermore, a slide rail and a slider along the vertical direction are arranged between the vertical base plate and the flipping mechanism, so as to ensure that the movement of the two is more stable.
