Test device using real-time measuring device for viscosity of liquid adhesive mixture

Abstract

The invention discloses a liquid adhesive viscosity real-time measurement apparatus and a test apparatus using same. The measurement apparatus comprises a supporting seat and a rotating shaft, wherein the rotating shaft is vertically arranged and circumferentially connected with the supporting seat in a rotating manner, the rotating shaft is provided with a permanent magnetic pole, the supporting seat is also provided with an induction coil, and the shaft section, which is disposed outside the supporting seat, of the rotating shaft is circumferentially provided with at least two blades; and when the blades are driven to rotate, a voltage signal is generated inside the induction coil. Compared with an existing viscometer in the prior art that can measure the viscosity only at a static state of adhesive, the liquid adhesive viscosity real-time measurement apparatus has the following advantages that: first, the viscosity of the adhesive is acquired in real time during the mixing period of the adhesive and a curing agent, i.e. the measurement of the viscosity of the adhesive at a dynamic mixing state can be realized; and second, by measuring various viscosity values of the adhesive and the curing agent at different mixing phases in real time, the mixing condition of the adhesive and the curing agent can be known by the test personnel.

Problems solved by technology

[0007] The bonded interface inevitably has many defects such as microcracks during the molding process. The opening and closing states of each microcrack are different when the temperature rises and cools down, which causes the coefficient of thermal expansion to rise and fall. The inconsistency of cracks or peeling layers will gradually increase, reducing the mechanical properties of the protective coating 6
