Suction head mechanism of annular product

Abstract

The invention discloses a suction head mechanism of an annular product. The suction head mechanism comprises a guide seat, a mounting seat and a suction head module which are sequentially stacked fromtop to bottom, the guide seat is provided with a groove A and a channel A, the groove A is a circular groove, the mounting seat is provided with a groove B, a groove C and a plurality of channels B,and the groove B is a circular groove; the plurality of channels B are sequentially and uniformly distributed at intervals along a first loop line, the suction head module comprises a suction head main body and a plurality of suction nozzles, the suction head main body is provided with a plurality of channels C, the plurality of channels C are sequentially and uniformly distributed at intervals along a second loop line, the groove A and the groove B are oppositely combined up and down to form an air equalizing cavity and an annular butt joint seam; a sealing ring used for blocking the butt joint seam is arranged in the air equalizing cavity, the upper end of the suction head main body extends into the groove C, the channels B communicate with the channels C to form an air suction channelsin a one-to-one correspondence mode, and the suction nozzles are connected with the air suction channels in a one-to-one correspondence mode. According to the suction head mechanism of the annular product, the sealing ring is arranged between the two workpieces, so that air leakage of a gap between the two workpieces is prevented, and the air tightness is prevented from being influenced.

Description

technical field [0001] The invention relates to the field of product pick-and-place, in particular to a suction head mechanism for ring-shaped products. Background technique [0002] At present, for the grasping of some small pieces, methods such as suction or making corresponding profiling clamping devices according to their shapes are usually used. However, for some products with high appearance requirements, the clamping device may cause the product to be scratched or deformed. At this time, the suction method is usually used. Suction plays a vital role in the effective absorption of products. Especially for some products with limited adsorption area, such as ring products, not only the precise position is required, but also the sealing of the suction head needs to be ensured, so as to have enough suction to absorb the product. Poor sealing of the suction head will lead to insufficient suction, which will affect the suction of the product. Especially when the adsorptio...
