Vacuum adsorption module

A vacuum adsorption module, comprising:

• a supporting block having a plurality of rows and columns of air connection holes distributed in an array, each row of air connection holes being connected to a total air path formed in the supporting block via a branch air path formed in the supporting block, the total air path in the supporting block is adapted to be connected to a vacuum pump;
• a carrier installed and positioned on the supporting block, the carrier having a plurality of rows and columns of air suction holes corresponding to the air connection holes in the supporting block, respectively, and distributed in an array, the air suction holes in the carrier are adapted to be docked with the air connection holes in the supporting block;
• and
• a plurality of valves installed on the supporting block, the plurality of valves being used to control closing and opening of the branch air paths between the plurality of rows of air connection holes and the total air path, each valve controls connection and disconnection of an air communication between one of the rows of air suction holes in the carrier and the vacuum pump, an adsorption length of the carrier in a column direction of the array is adjustable to match a length of an article to be adsorbed by the carrier by changing a number of the valves to be closed or opened.
