Title:
DUAL-PURPOSE WORKTABLE
Document Type and Number:
WIPO Patent Application WO/2021/212766
Kind Code:
A1
Abstract:
A dual-purpose worktable, comprising a carrying base (1) and a carrying plate (3) which are selectively used to carry a workpiece (2). The carrying plate (3) has a working surface (31), an abutting surface (34), a negative pressure through hole (32), and a groove (33) communicated with the negative pressure through hole, wherein the groove (33) is formed in the working surface (31). When the carrying plate (3) is placed on the carrying base (1), the abutting surface (34) of the carrying plate (3) abuts against an upper surface (111) of the carrying base (1); and between the workpiece (2) and the working surface (31) of the carrying plate (3), a negative pressure suction force of a negative pressure apparatus (4) reaches the groove (33) in the working surface (31) through an air suction hole (112) and the negative pressure through hole (32), until a negative pressure state is formed in the groove (33), so that the workpiece (2) placed on the working surface (31) is suctioned. Or, only the carrying base (1) is used to carry the workpiece (2) for subsequent processing procedures, and a desired worktable can be used flexibly according to different workpiece requirements.
