Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Referring to fig. 1, the present embodiment discloses a workpiece suction device for sucking and fixing a workpiece to convey the workpiece, and particularly for sucking and fixing a workpiece with a smooth surface, such as a hardware plate, a plastic plate, a box with a square shape, and the like. The work piece suction means in this embodiment includes first flexible driving piece 30 and, two suction assemblies 50, and suction assemblies 50 includes linear spring 53 and sucker structure, and linear spring 53's one end is connected in the expansion end of first flexible driving piece 30, and linear spring 53's the other end and sucker structure are connected, and under the drive of first flexible driving piece 30, linear spring 53 orders about sucker structure and presses to the work piece surface and absorbs the work piece. In this embodiment, two suction cup structures are used to suck two different positions of the workpiece surface, so as to improve the sucking firmness, and in addition, since the linear spring 53 has flexibility, when there is a height difference or unevenness on the workpiece surface, for example, the workpiece surface is inclined or there is a higher plane and a lower plane on the workpiece surface, the two suction cup structures can respectively make adaptive position changes independently of each other, so as to firmly suck and fix the workpiece surface.

Next, the structure of the work sucking apparatus will be further described.

The workpiece suction device further includes a second telescopic driving element 40, and the first telescopic driving element 30 and the second telescopic driving element 40 are both cylinders with movable ends moving along a straight line.
