Description

TECHNICAL FIELD

[0002] The vacuum chuck is usually composed of a chuck body, a connecting part and a sealing element, and the vacuum chuck is used to generate negative pressure by vacuum principle to adsorb and fix objects, and is widely used in material handling, positioning, assembly and other links in industrial automation production, and some simple adsorption fixing scenes in daily life, which can efficiently and conveniently realize the grabbing and moving of objects, improve production efficiency and reduce labor intensity.

[0003] The existing part of the vacuum chuck realizes the self-adaptive adsorption function by setting multiple micro-holes on the surface of the chuck.

When facing the workpiece with an arc curved surface, the multiple micro-holes are difficult to fully and closely fit the arc surface due to the irregular shape of the arc curved surface, resulting in a smaller actual adsorption contact area. In the processing process, due to the insufficient adsorption contact area, the adsorption force is limited, which cannot effectively overcome the influence of external factors (such as the weight of the workpiece, vibration in the processing process, external force impact, etc.), and the workpiece is easy to fall off, which can cause safety accidents, threaten the processing equipment and the operator, and also reduce the processing quality and the qualified rate of the product.
