The invention discloses a manufacturing process of a mobile phone camera lens. The manufacturing process comprises the steps of cutting, laser cutting, ultrasonic cleaning, etching, tempering, tertiary silk-screen printing, NCVM electroplating, deplating, AR plating, AF plating, splitting, film coating and inspection. Compared with a small piece CNC technological process, the technological processhas the advantages that manual processes such as piece placing and dispensing after cutting are omitted, manual processes such as tempered frame inserting and frame taking are omitted, and manual stations such as piece placing in silk-screen printing are omitted; the appearance precision of the product is improved; the laser cutting process is used for scribing the outer contour, so that the boundary dimension precision of the product is improved and appearance, size and precision of the product are improved; a secondary tempering process is adopted, so that the impact strength of the cameralens is improved, and the spontaneous explosion rate is reduced; and the yield is improved: the comprehensive yield of the product is averagely improved by more than 10%.
