Description

Electrochromic device

Technical Field

The utility model relates to the technical field of manufacturing of automobile rearview mirrors, in particular to an electrochromic device.

Background

Common automobile rearview mirrors are divided into an automobile inner mirror and an automobile outer mirror, and if the automobile rearview mirrors are subjected to strong light direct irradiation, glare is easy to occur, normal driving of an automobile owner is affected, and safety accidents can be possibly caused. Electrochromic rearview mirrors have appeared in the field of automobile rearview mirror manufacturing at present, and the principle is that the light intensity is detected in time through a sensor, and the principle that the electrochromic liquid can reversibly change color under the action of an electric field is utilized, so that strong light is eliminated.

The electrochromic rearview mirror is designed to improve the appearance attractiveness, a borderless structure is designed, the step of manufacturing the borderless rearview mirror by utilizing an electrochromic principle is generally that an upper piece of glass or a lower piece of glass is firstly placed on a fitting device tool, a circle of frame glue is arranged on a film plating surface of the glass along the edge of the glass, a gap of 1.6-2.0 mm is reserved, the device grabs another piece of glass (the film plating surfaces of the two pieces of glass are oppositely arranged) for fitting, then the 2 points or 4 points of UV glue are arranged on the combined edge of the two pieces of glass, then the UV glue is cured by a UV lamp, after the operation is finished, the glass is transferred into an oven for 1.5 hours, after the baking is finished, the conducting glue is added on the edges of the two sides of the glass, after the baking is carried out for 1 hour, the filling is carried out, UV curing is sealed, and finally the glass is transferred into the oven for 1 hour, and the 140 ℃ baking ageing is carried out, so that the manufacturing of the electrochromic rearview mirror is finished. However, the frameless rearview mirror has the problem that the manufacturing efficiency is not ideal enough, and in order to improve the manufacturing efficiency, the frame glue and the conductive glue can be simultaneously dispensed, so that the baking of the frame glue and the conductive glue can be concentrated together, and the manufacturing efficiency is effectively improved. However, in the synchronous point coating method, when two pieces of glass are adhered, because the glass is adhered and has a extrusion force, the frame glue and the conductive glue which are relatively close to each other can be mixed together, so that the sealing effect of the frame glue can be influenced, and the conductive effect of the conductive glue can be influenced, and therefore, the structure of the frame-free rearview mirror manufactured by the improved manufacturing process needs to be further improved.
