Tool and method for batch preparation of tensile shear strength samples of adhesive

The invention discloses a tool and a method for batch preparation of tensile shear strength samples of an adhesive. The tool comprises an electromagnet base used for adsorbing a substrate, wherein a lower glass plate used for bearing a lower plate substrate is fixedly connected above the electromagnet base; an upper glass plate used for bearing an upper plate substrate is fixedly connected above the lower glass plate; and a marking line used for positioning the upper plate substrate is arranged on the lower glass plate. The invention is simple in structure and convenient to use, wherein the lower glass plate and the upper glass plate are sequentially arranged on the electromagnetic base from bottom to top, and the marking line is arranged on the lower glass plate, thereby facilitating thepositioning and fixing of a sample substrate, guaranteeing the parallelism of a plurality of samples, and greatly reducing the dependence on the technical level of operators, and the substrate is fixed through electromagnetic
