Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a real-time polymer monitoring device in a laminator. Background Technology

[0002] Polymers are high molecular weight compounds formed by repeated chemical bonds connecting many identical, simple structural units. They are a type of high molecular weight material and are indispensable in fields such as electronics and aerospace.

[0003] Research on the relationship between polymer structure and properties has been continuously developing, from the initial macroscopic to the microscopic molecular level, from qualitative to semi-quantitative or even quantitative analysis, and from static reaction product analysis to more comprehensive multi-physics coupling analysis of the reaction process. However, current macroscopic observations of polymer reactions are mostly conducted in laboratory settings under non-realistic conditions, using devices such as beakers or small cavity molds. This makes it difficult to simulate the polymer reaction results under real-world conditions involving multi-physics coupling, such as heat and force. This is especially true for complex cavity structures like modular panels, where existing reaction observation devices are insufficient to assess the polymer flow state during the reaction within the complex cavities, as well as the post-reaction state of surface porosity, internal pore defects, and the degree of polymer filling at corners or obstructions. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a real-time polymer monitoring device for a laminator. This device can be placed in the laminator to simulate the flow state and post-reaction quality of polymers under real thermodynamic and other multi-physical field coupling conditions. This provides a basis for adjusting polymer reaction parameters and designing reaction cavities, enabling more precise control of the polymer reaction quality.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a real-time polymer observation device in a laminator, comprising a frame, a metal plate, a transparent plate and a high-speed photography component.

[0007] The frame is made of welded metal square tubing.

[0008] The metal plate mentioned is a metal plate used for the skin of the modular cabin, simulating the bonding performance between the polymer reaction and the cabin skin.

[0009] The transparent plate is made of transparent acrylic and is used to observe the surface quality after the polymer reaction.

[0010] The placing hole is arranged at the opposite side of the injection hole.

[0011] The placing hole is closed by a transparent sheet for protecting the high-speed photography assembly.
