Background

The adhesive is a substance with good adhesive property, which plays a role in connecting objects by surface adhesion through adhesion and cohesion, and is used for testing the tensile force which is an important index for testing the adhesive property, and the standard GB/T6329-1996 defines the principle of the adhesive tensile test as follows: the sample joint is formed by butt joint of two square or round bar-shaped adherends, as shown in fig. 1, the adhesive joint surface is perpendicular to the longitudinal axis of the sample, and the tensile force is transmitted to the adhesive joint surface through the longitudinal axis of the sample until the sample is broken. When the sample is prepared, two sample joints are bonded by an adhesive and then applied with certain external pressure, and after the two sample joints are kept still for a set time, a tensile test can be performed, and in order to improve the accuracy and the referenceability of the test, the standard also prescribes that the number of samples required by one test is not less than five. In the prior art, the preparation of the samples is that the single samples are prepared one by one, and because of the individual difference of artificial pressure, the adhesion force of each prepared sample can be different to influence the test authenticity, and the single sample preparation efficiency is low to compare, so that the requirement of test speed can not be met, and how to develop a tool for rapidly preparing the samples becomes a difficult problem to be solved urgently.
