Adhesive flow testing device and testing method

Abstract

The invention discloses an adhesive flow testing device. The device comprises a base, a protection cover, a detection chamber, a display panel, a humidifying device, a drying device, a detection device and a control device, wherein the detection chamber is defined by toughened glass plates and a base; operation holes and rubber gloves are arranged on one toughened glass plate; the control device controls the humidifying device and the drying device to work; the detection device is placed in the detection chamber; the humidifying device, the drying device and the control device are placed in achamber defined by the base and the protection cover. The invention further discloses a testing method adopting the adhesive flow testing device. As a movable miniature detection chamber, the cost forproviding the required detection environment is much lower than that for controlling the laboratory environment, and materials can be drawn from the production line at any time for detection at any time; the provided detection device can detect fluidity of the adhesive on line; operators can be protected from harm caused by volatile substances of adhesives.

Description

technical field [0001] The invention relates to the field of adhesive performance testing, in particular to an adhesive flow testing device and a testing method. Background technique [0002] Adhesive bonding (bonding, bonding, cementation, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives. It has the characteristics of continuous stress distribution, light weight, or sealing, and low temperature in most processes. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is the fastest growing in modern times, with a wide range of applications, and has a major impact on the progress of high-tech science and technology and the improvement of people's daily life. A class of organic or inorganic, natural or synthetic substances that can connect the same, two or more homogeneous or heterogeneous parts (or materials) toget...

AI Technical Summary

Problems solved by technology

The fluidity of the adhesive has a crucial influence on the quality of the bonding between objects. Poor fluidity of the adhesive will cause insufficient filling of the adhesive during the bonding process and affect the bonding strength.

[0003] There are 7 recommended methods for testing the fluidity of adhesives in my country (refer to GB / T31113-5014). It is carried out in the laboratory, so it is impossible to detect the glue in real time, and the laboratory space is large, and the cost of environmental control is high
