Summary:The invention relates to a bar code reading engine, in particular to an ultra-wide-angle code scanning engine. Comprising a front shell, a first circuit board and a second circuit board, the second circuit board is in communication connection with the first circuit board, and the second circuit board is fixedly connected with the front shell and a rear shell; a first illumination lens and a second illumination lens are arranged on the front portion of the front shell, the surface type of the first illumination lens and the surface type of the second illumination lens are of a free-form surface structure, and the free-form surface structure enables light rays emitted from the first illumination lens and the second illumination lens to be distributed in the mode that the middle is weak and the two sides are strong. The light intensity distribution and the image surface illuminance distribution of the optical lens are complementary, the effect of enhancing the edge brightness of a picture is achieved, the two il
