Abstract

The utility model provides a film pasting jig for a head-up display diffraction waveguide, which comprises a support piece, wherein a first through hole is formed in the support piece, a plurality of support parts are arranged at intervals around the first through hole on the edge of the bottom surface of the support piece, and the support parts are arranged corresponding to a plurality of first positioning parts arranged on a film layer to be pasted. When the film sticking jig is used for sticking a film of a UV (ultraviolet) mucosa-reducing film on a head-up display diffraction waveguide, the self-rolling and adhesion of the UV mucosa-reducing film cannot be caused in the process of tearing off a release film, so that the UV mucosa-reducing film cannot be used, the problems of foaming, wrinkling and the like cannot occur in the process of sticking the UV mucosa-reducing film on the head-up display diffraction waveguide, and a single operator can finish the sticking operation of the UV mucosa-reducing film on the head-up display diffraction waveguide through the film sticking jig.

Description

Film pasting jig for head-up display diffraction waveguide Technical Field The utility model belongs to the technical field of head-up display diffraction waveguides, and particularly relates to a film pasting jig for a head-up display diffraction waveguide. Background Head-Up Display (HUD) is a technology of projecting contents such as travel information and navigation information onto a Display screen or a windshield. Therefore, the HUD can integrate contents such as driving information, navigation information and the like with road conditions in a real traffic scene, and an interactive feedback information loop is built between the real world, the information world and a user, so that the perception of the driving information by the user is improved. In one implementation, the HUD may be implemented based on an augmented reality display technique that enables a user to simultaneously view information in the real world, such as images or data superimposed in the real world. The augmented reality display technology mainly comprises a coaxial side view prism scheme, an array semi-permeable membrane waveguide scheme, a free-form surface scheme, a diffraction waveguide scheme and the like, and the display performances of different schemes are different. Among them, the diffraction waveguide scheme is widely used due to its advantages of small size, light weight, etc. The diffraction waveguide for head-up display includes an in-coupling grating region and an out-coupling grating region, and in order to increase the in-coupling light efficiency of the in-coupling grating region, a coating operation is required to be performed on the in-coupling grating region of the head-up display diffraction waveguide. Before coating operation is performed on the coupling grating area of the head-up display diffraction waveguide, other areas except the coupling grating area of the head-up display diffraction waveguide are required to be covered by adopting UV (ultraviolet) mucous membrane reduction, and after the coating operation is completed on the coupling grating area of the head-up display diffraction waveguide, the UV mucous membrane reduction of the head-up display diffraction waveguide is stripped and removed. In the process of covering other areas of the head-up display diffraction waveguide except for the areas coupled with the grating by adopting UV (ultraviolet) mucous membrane reducing agents, the UV mucous membrane reducing agents need to be adhered to the other areas of the head-up display diffraction waveguide except for the areas coupled with the grating, and the existing process of adhering the UV mucous membrane reducing agents to the other areas of the head-up display diffraction waveguide except for the areas coupled with the grating has the following problems: 1. Before being adhered to use, the UV subtracts the mucous membrane adhesion to from the type membrane, in the in-process of subtracting mucous membrane with UV and separating from the type membrane, cause the UV to subtract the mucous membrane from rolling up and adhesion easily because of reasons such as elasticity and static of membrane, and then lead to the UV to subtract the mucous membrane to be unable to use easily. 2. In the operation process of pasting the UV mucous membrane of the head-up display diffraction waveguide, the problem that foaming, wrinkling and the like easily occur to the UV mucous membrane pasted on the head-up display diffraction waveguide. 3. Because the waveguide area of the head-up display diffraction waveguide is large, the existing single operator cannot finish the sticking operation of the UV (ultraviolet) mucous membrane of the head-up display diffraction waveguide.
