Apparatus and method for coating elastic glue on optical window

Abstract

The invention belongs to the technical field of optical window bonding for optical machine assembly, and in particular relates to an elastic glue coating device and method for optical windows. Aiming at the deficiencies of existing coating methods, the electric rotating coating device of the present invention can carry out elastic glue coating on the optical window through the mode of manual speed regulation, and its coating method is changed from continuous coating to point coating, which improves It improves the uniformity of the adhesive layer, reduces the workload of wiping, and avoids environmental pollution and waste. Its advantage is that the structure is simple, and the attitude of the optical window can be quickly adjusted, and the surface to be coated can be adjusted in place to maintain stability. The material and shape of the tool have been redesigned to reduce the operational risk of the optical window.

Description

technical field [0001] The invention belongs to the technical field of optical window bonding for optical machine assembly, and in particular relates to an elastic glue coating device and method for optical windows. Background technique [0002] The optical window is an important part of the photoelectric system. While ensuring that the product has good optical, mechanical and thermal properties, in order to reduce the assembly stress and ensure reliable fixation, elastic adhesive is used between the optical window and the metal parts. At present, the elastic There are two methods of coating: the first is to place the window on a soft material foam support, and use a rolling stick to coat, and after coating one surface, turn the foam to coat the next surface; the second method is to pick up the optical window by hand. Window turned position for coating. Both methods have disadvantages. The first one is that the friction force of the foam support is increased, and it is not ...

AI Technical Summary

Problems solved by technology

Both methods have disadvantages. The first one is that the friction force of the foam support is increased, and it is not easy to rotate on the workbench; the second method is that due to the heavy weight of the optical window, frequent manual operations increase the risk of operational safety, and the use of coating tools Improper use can also lead to a risk of scratching the optical window

Therefore existing tools and methods are not suitable for coating work
