Abstract

The application discloses a high parallelism installation method of a large target surface sensor and a camera. The installation method includes: step 1, fixing the front shell and the lens flange on the processing platform respectively, Parallelism processing, wherein, the processing plane of the front shell includes the third plane and the fourth plane, and the processing plane of the lens flange includes the first plane and the second plane; step 2, according to the first positioning hole and the first positioning post, the The processed front shell and the processed lens flange are assembled, which is recorded as an assembly; step 3, based on the first plane of the lens flange, fix the assembly on the processing platform; step 4, the front shell The sensor mounting surface is processed for parallelism, and the processed sensor mounting surface is parallel to the first plane of the lens flange. Through the technical solution in this application, it is beneficial to reduce the cumulative error of the parallelism between the sensor assembly surface and the lens, thereby improving the imaging effect of the image sensor.

Description

technical field [0001] The present application relates to the technical field of camera sensors, in particular, to a high-parallel installation method of a large target surface sensor and a camera. Background technique [0002] During the imaging process of the camera, the image sensor is required to be parallel to the lens, that is, the sensor assembly surface is parallel to the lens flange plane, so as to ensure a good imaging effect of the camera. The sensor assembly surface is set on the rear side of the front shell, and the lens The flange is mounted on the front side of the front case. Usually, the lens flange and the front shell are processed separately through high-precision positioning tooling, and then glued together to ensure the parallelism between the lens flange and the sensor assembly surface. [0003] In the prior art, on the one hand, the cost of positioning tooling is high, and it cannot be disassembled after being glued, which is not conducive to the main...
