Problems solved by technology

For example, optical fir glue needs to be heated and melted before it can be applied, which undoubtedly increases the complexity and difficulty of application; photosensitive curing glue needs to be cured by ultraviolet light, which greatly increases the processing cost
Existing gluing applications use manual operation to remove air bubbles, the operation quality is unstable, and there is artificial damage to the parts
Existing adhesive and gluing applications place significant constraints on production of darkening welding goggles

Embodiment Construction

[0009] Because the bonding strength of the silicone rubber adhesive used in this program is not very high and can meet the optical requirements, the present invention adopts the silicone rubber adhesive to replace other traditional adhesives such as optical fir glue, epoxy resin glue, Photosensitive curing glue, etc. The silicone rubber adhesive in the present invention can be commercially available transparent one-component, two-component low-adhesive strength silicone rubber cured at room temperature. Since the bonding strength of these silicone rubber adhesives is not very high, they are just suitable for the bonding between the optical filter element of the present invention and the liquid crystal light valve. In this way, the filter elements and liquid crystal light valves with bonding problems can be disassembled and reworked. The above-mentioned silicone rubber adhesive does not need special treatment, and is cured by reaction at normal temperature and pressure.

Abstract

The invention discloses an applying method of silicon rubber adhesive in optical change welding goggle adherence. It uses silicon rubber adhesive between filer part and crystalline liquid light valve to do adherence, and then extracts the air and eliminates the bubble between them. The silicon rubber adhesive adopts normal temperature reaction to modulate.

Description

technical field [0001] The invention relates to an application method of a silicone rubber adhesive in gluing darkening welding goggles. Background technique [0002] At present, the optical filter element and the liquid crystal light valve need to be glued together with an adhesive during assembly of the dimming welding goggles to meet the impact performance requirements of the product. Automatic darkening welding goggles have requirements for visible light transmittance, so optical parts are glued with adhesives in production, such as optical fir glue, epoxy resin glue, photosensitive curing glue, etc. These adhesives generally have high cost, very long curing time, and low production efficiency in actual use. Moreover, these adhesives are relatively viscous and cannot be removed after gluing. If there is a problem of poor gluing quality, the filter element and The LCD light valve cannot be disassembled for repair. The requirements for the bonding strength between the fi...
