AI Technical Summary
Due to the size limitations of the existing automotive display screen, the positioning and fitting method has no space to arrange silk screen lines on the lens, which cannot achieve accurate alignment and surface difference control, especially in the design of large curved screens and triple screens.
A new positioning and fitting method is adopted that combines the metal bracket with the lens cover. By setting a circular hole on the metal bracket and adding silk screen lines on the lens cover, the silk screen lines are used for photographing and alignment, and the fitting is carried out through the pressing fixture in the Z direction, the gap surface difference control in the X/Y/Z direction is achieved.
Accurate alignment and surface difference control are achieved, solving the problem of screen printing lines arranged on the lens cover plate without space in traditional technology, and improving the convenience and accuracy of large-scale screen fitting.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile display screens, in particular to a triple screen with a novel positioning and laminating method. Background Art
[0002] The existing method of positioning the car screen is to use a mark line (a kind of silk screen line) for positioning, and then fix the lens assembly and the metal bracket with structural adhesive to form an assembly. The existing technology is limited by size, resulting in no space on the lens for silk screen lines, making it impossible to position and fit the product. In order to make the interior look beautiful, car companies now use larger curved screens and large-size triple screens (1-1.2m), and also use a thin and light-frame design for the display screen. Since the front of the product is all glass lenses, in order to increase the strength and fitting area of the glass lenses, the periphery of the front bracket behind the synchronous glass lens will be consistent with the lens, which will make it impossible to arrange silk screen lines on the lens, and the traditional process of adding silk screen lines on the periphery of the metal bracket cannot be realized.
[0003] Therefore, a triple screen with a new positioning and lamination method is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a triple screen with a novel positioning and laminating method to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a triple screen with a new positioning and bonding method, including a lens cover, optical water glue, a display screen, a backlight source, and a metal bracket. The display screen is bonded to the lens cover plate by optical water glue, the backlight source is installed on one side of the display screen, the metal bracket is provided with a first circular hole and a second circular hole, and the surface of the lens cover plate is provided with a first silk-screen line and a second silk-screen line.
[0006] Preferably, the display screens are provided in three groups, the first circular hole is located on the left side of the left display screen, there is a gap between the middle display screen and the right display screen, and the second circular hole is located between the middle display screen and the right display screen.
[0007] Preferably, the first silk-screen line and the second silk-screen line are both arranged in a cross shape.
[0008] Preferably, the metal bracket is installed on one side of the backlight source by means of structural adhesive.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The utility model adopts a metal bracket, which can be photographed and aligned by the first silk-screen line and the second silk-screen line during bonding, and then the bonding is performed after the pressing fixture is moved downward 5mm in the Z direction. This not only allows accurate alignment, but also can accurately control the gap surface difference in the three directions of X / Y / Z. The metal bracket has a hole, and the lens cover plate has a silk-screen line, which is convenient for photographing and alignment, and can also solve the problem of no space for silk-screen lines on the edge in the traditional way.
[0011] 2. The metal bracket is opened with holes, and the lens cover is partially added with silk screen line positioning. Not only the position in the X and Y directions is positioned, and the surface difference in the Z direction is controllable, but also the problem of no space for silk screen arrangement on the lens cover can be solved. At the same time, it can also solve the alignment inspection of camera equipment and assist visual inspection, which is extremely convenient for large screen bonding.
