Description
Technical Field
The invention relates to the technical field of camera assembly, in particular to a light source assembly for wide-angle AA equipment.
Background
Currently, for electronic products such as mobile phones, cameras are undoubtedly a major factor to embody the performance of the electronic products. In addition, the mobile phone with the high-performance camera is popular in the market and occupies a larger share in the market due to the change of the consumer concept and the living demand. When the camera is manufactured, the semi-finished product is required to be placed on a manufacturing station, and then the sensor is fixed on the semi-finished product to be coupled. In order to ensure the performance of the camera, the semi-finished product must obtain the best coupling position with the sensor when coupling. To solve this problem, the AA mechanism is usually used to adjust the position of the semifinished product and the sensor during coupling, i.e. the AA process.
The AA technology, namely Active Alignment, is interpreted as Chinese, namely Active Alignment, and is a technology for determining the relative position in the assembly process of parts. In the AA process apparatus, when assembling each component, the apparatus will detect the assembled semi-finished product, actively align the semi-finished product according to the actual situation of the assembled semi-finished product, and then assemble the next component in place. The active alignment technology can adjust the lens alignment to 6 degrees of freedom (X, Y, Z, thetax, thetay and thetaz), effectively reduce the assembly tolerance of the whole module, effectively improve the consistency of camera products, and create possibility for higher-order camera product packaging.
In the AA alignment process, a varifocal lens is required to be matched with a camera module to focus a chart, and different varifocal lenses are required to be adopted for manufacturing different cameras. After the AA is finished, the ordinary camera usually adopts a white light source to correct OC (optical centering) and detect dirt, and comprises the following steps: 1. a white light source images a binary image on a chip through a lens; 2. calculating the position of the central point of the imaging binarization image; 3. calculating the offset of the central point of the lens by software; 4. and calculating the offset to enable the center of the optical axis of the lens to coincide with the optical axis of the sensor. In order to realize the steps, a white field luminous plate is required to be arranged between the AA head jig gland and the distance-increasing lens base to carry out OC correction on the white light source.
At present, the most advanced six-axis four-station wide-angle AA equipment for manufacturing the wide-angle camera has the defects that the distance between bases of the distance increasing lenses and a gland of an AA head jig is only 10-20 mm due to the large volume of the distance increasing lenses, and a white field plate cannot be installed due to the small space. Therefore, OC correction is carried out on the existing six-axis four-station wide-angle AA equipment only by adopting a chart, and a test result shows that the OC correction precision of the chart correction mode is obviously lower than that of a white light source OC correction mode, and the pollutant detection cannot be carried out without a light source on the chart correction OC, so that the assembly process of the manufactured wide-angle camera is reduced, the problems of low yield, increased cost and the like in the production process of products are caused, and the burden of enterprises is increased.
