Technical Field

[0001] The present invention relates to the technical field of digital image source product production, and specifically to a high-precision assembly positioning fixture and method for a panel-integrated digital image source. Background Art

[0002] Due to the special use environment and imaging principle of digital image source products, during production, high requirements are placed on the installation accuracy of the screen and structural parts. Generally, it is required that the distance accuracy between the display image plane and the installation plane of the product be controlled within 30 μm, and the parallelism accuracy between the display image plane and the connection line of the structural installation holes be controlled within 1'. The installation of such products needs to be carried out with the assistance of an imaging instrument. Digital image source products larger than 1 inch can be designed as panel-separated types, and the relative position with the structure can be achieved by moving the screen through a tooling under the imaging instrument. For products smaller than 1 inch, due to size limitations, they cannot be designed as panel-separated types, and the above method is no longer applicable. Summary of the Invention
