[0002] Adhesives can connect the surfaces of homogeneous or heterogeneous objects together. Relevant tests will be involved in the development and application of adhesives. Some of the tests will require the production of shear pieces of specified thickness to test the shear strength of the adhesive. The conventional adhesive layer thickness is 0.2mm. Under different working conditions, it is also necessary to test the shear strength at different thicknesses such as 0.5mm, 1mm, 1.5mm, and 2mm. Therefore, it is necessary to ensure the thickness of the glue coating between the shear pieces.

The PTFE bonding module is removably embedded in the base. A first positioning groove is provided in the upper substrate positioning area, and the first positioning groove extends from the substrate positioning area through the upper step portion of the PTFE bonding module to the connection between the upper step portion and the lower step portion. The PTFE gasket is placed in the first positioning groove to control the thickness of the adhesive; the upper substrate is placed above the PTFE gasket of the first positioning groove, and the lower substrate is placed in the second positioning groove.
