An adsorption positioning device suitable for installation on a cutting machine, which is suitable for cutting a material unit, includes a platform and two platen units. The platform includes a table for supporting the material unit, and a plurality of air holes extending through the table. The platen units are disposed on the table. The table and each platen unit are configured for cooperating with a lateral side of the material unit to define a channel that communicates with corresponding ones of air holes. The channel and the air holes are suitable for causing the material unit to be adsorbed on the table under a negative pressure state.

1. An adsorption positioning device suitable for installation on a cutting machine, the cutting machine being suitable for cutting a material unit, said adsorption positioning device comprising: a platform including a table suitable for supporting the material unit, and a plurality of air holes extending through said table and communicating with an external environment; and two platen units disposed on said table and spaced apart from each other along a first direction, each of said platen units extending along a second direction perpendicular to the first direction, said table and each of said platen units being configured for cooperating with a lateral side of the material unit to define a channel that communicates with corresponding ones of said air holes, each of said platen units including a platen that has a press portion suitable for pressing the lateral side of the material unit, said channel and said air holes being suitable for causing the material unit to be adsorbed on said table under a negative pressure state.

2. The adsorption positioning device as claimed in claim 1, wherein said platen further has a cover portion adjacent to said press portion, said cover portion having one side that is distal to said press portion abutting against said table.

3. The adsorption positioning device as claimed in claim 1, further comprising a pressing rod unit that is disposed on said table and that includes a pressing rod, said platen units being connected to said pressing rod, said pressing rod and said table cooperatively defining a feeding space suitable for passage of the material unit therethrough along the second direction.

4. The adsorption positioning device as claimed in claim 3, wherein said pressing rod unit further includes two tracks spaced apart from each other along the first direction, said pressing rod being movably disposed between said tracks for adjusting a height of said feeding space.

5. The adsorption positioning device as claimed in claim 3, wherein each of said platen units further includes a slide member that is disposed on said pressing rod, that is movable along a length of said pressing rod and that is connected to said platen.

6. The adsorption positioning device as claimed in claim 5, wherein said slide member includes a first connecting portion extending along the second direction, and a connecting pin disposed on and extending upwardly from said first connecting portion, said platen further having a first pin hole proximate to one end thereof and being connected to said first connecting portion by extending said connecting pin through said first pin hole.

7. The adsorption positioning device as claimed in claim 6, wherein said slide member further includes a second connecting portion extending over said pressing rod, each of said platen units further including a guide member that is connected to said second connecting portion and that has a supporting portion and a limiting portion perpendicularly intersecting each other, said supporting portion being suitable for supporting a bottom surface of the material unit, said limiting portion being suitable for abutting against the lateral side of the material unit.

8. The adsorption positioning device as claimed in claim 6, wherein each of said platen units further includes a first plate member and a second plate member stacked one above the other and disposed between said platen and said table, said first plate member having a plurality of perforations communicating with corresponding ones of said air holes, said second plate member having a plurality of notches formed on one lateral side thereof that faces the material unit and communicating with said channel and corresponding ones of said perforations.

9. The adsorption positioning device as claimed in claim 8, wherein said second plate member has a second pin hole proximate to one end thereof, and is connected to said first connecting portion by extending said connecting pin through said second pin hole.

10. The adsorption positioning device as claimed in claim 2, wherein each of said platen units further includes a sealing member connected between said cover portion and said table.
