Multifunctional vacuum suction platform

The invention discloses a multifunctional vacuum suction platform. The platform comprises an annular mounting plate, an annular plate and a disc; the disc is arranged in the annular mounting plate, and the disc is fixedly connected with the annular mounting plate; the annular plate is fixed at the portion, located on the outer side of the disc, in the annular mounting plate in a sleeve connectionmode, and the annular plate is fixedly connected with the annular mounting plate; the connecting sections of the disc and the annular plate penetrate through the top and the bottom of the annular mounting plate; and avoiding grooves and vacuum holes are formed in the top of the disc and the top of the annular plate at equal intervals. According to the platform, an optical sensing head is arrangedon a placing plate, and optical sensing is carried out at the upper position and the lower position of the vacuum suction platform according to the measurement requirement; due to the arrangement of the avoiding grooves and th
