Description
Technical Field
The utility model relates to the technical field of vacuum clamping devices, in particular to a vacuum composite sucker for bonding the detection surface of an elastomer.
Background
Because the elastomer material has the characteristics of easy stress deformation, shape recovery after deformation and the like, the stress-strain property and detection of the elastomer material are very basic and common work in research and engineering of the material. Compared with the very mature standardized method of preparing standard sample bars for mechanical test, the method is a field which is recently reported for online detection of the elastomer under working conditions, but in practical application scenes, such as automobile tires, living biological materials which can not be used for sample preparation, biological soft tissues and other elastomer materials, online stress-strain detection means are necessary.
In the material mechanics test in the above scenario, one significant difficulty is the effective connection of the test tip to the object under test: most online tests are directed to objects in operation, or living biological tissue, i.e., non-destructive, non-invasive, requiring testing means, and therefore most mechanical clamping means cannot be used. For example, negishi T, ito K, kamono a et al articles Strain-rate dependence of viscous properties of the plantar soft tissue identified by aspherical indentation test J Mech Behav Biomed mate 2020; 102:103370 discloses a plantar tapping device which is intended to test the stress-strain properties of plantar soft tissue, but the test end (hammer) used cannot be effectively connected to the plantar, and only gives simple single hammering-relaxation data, which is far from the dynamic periodic stress-strain detection in classical material mechanics.
It is easy to think that the vacuum chuck is a good connection means capable of effectively connecting and grabbing the surface of the elastomer and applying force in multiple directions, for example, a soft tissue on-line dynamic mechanical analysis and detection system of China patent CN116263390A, a soft tissue periodic shear stress-strain on-line detection system of CN116263389A, a soft tissue periodic torque stress-strain on-line detection system of CN116263388A, and a plantar soft tissue on-body multidimensional stress-strain detection device of CN115500814A, all refer to a scheme for connecting a test end and a tested object by adopting the vacuum chuck.
However, in the above technical documents, the detailed design of the vacuum chuck is not specifically described. In fact, it is found in practice that the vacuum chuck commonly found in the market at present cannot well meet the requirement of on-line detection of the elastomer. According to different preparation materials, the existing vacuum suction cup is divided into a hard suction cup and a soft suction cup. The former can be prepared from metal, hard plastic, hard rubber and the like, and does not deform in the vacuum adsorption process, but has poor adsorption effect and is easy to fall off under the condition of larger stroke or torque; the soft sucker is generally made of soft rubber, silica gel and other deformable materials, and can be well adsorbed and attached to the sucked surface when vacuum is applied, but the soft sucker can deform in the stress process, so that the detection precision and stability can be greatly influenced when the soft sucker is used for material detection.
Therefore, based on the special requirement of on-line detection of the elastomer, the vacuum chuck should have a hard bonding surface to ensure the stability of the detected surface, and not influence the detection result due to stress-strain of the vacuum chuck, but also have good bonding property to ensure that the vacuum chuck does not fall off even if larger stress or torque is applied in the test process.
