2) upper tooling and lower tooling are fixed in Material Testing Machine, tooling, the spacing of lower tooling in adjustment, hook hook
Firmly fixing seat with holes, Material Testing Machine loading are reset,
3) with constant speed riding material testing machine, until two panels glass phase separates,
4) relevant test data is recorded, and is saved,
5) Material Testing Machine board resets, and removes glass, completes test.
Above-mentioned material testing machine is connected by data line with the computer of analysis data, in riding material testing machine, glass
The peel-force data of glass can be recorded in real time by computer and be come out.
The cohesive force of above-mentioned double-sided adhesive and the glass bonding is greater than 250N, the stickup of double-sided adhesive and the fixing seat with holes
Cohesive force be greater than 250N.The cohesive force of double-sided adhesive and glass and fixing seat with holes is stronger, using the double-sided adhesive of above-mentioned setting value,
Can two sheet glass separate when double-sided adhesive do not separated with glass or pedestal with holes.
Compared with prior art, the utility model has the following beneficial effects:
Cost is relatively low for the peel test force auxiliary fixture of the utility model, without being reequiped or being added to Material Testing Machine
Work need to only make upper and lower tooling and fixing seat with holes with hook, highly-safe, can be adapted for the glass of different-thickness, grasp
It is reliable to make process safety, and this jig Z-direction concentricity is accurately high, test data is stablized, and repeatability is higher.
