Optical lens and electronic equipment applying same

Abstract

The invention provides an optical lens and electronic equipment applying the same.The optical lens comprises a lens barrel and at least one lens body, a stop part and an optical filter which are sequentially arranged in the lens barrel from the object side to the image side; the outer diameter of the optical filter is larger than that of the stop part, and a glue dispensing groove protruding towards the object side is formed among the optical filter, the lens barrel and the stop part and used for containing glue, so that the stop part, the optical filter and the lens barrel are tightly fixed by means of the glue.Due to the fact that the outer diameter of the optical filter is larger than that of the stop part, and the glue dispensing groove protruding towards the object side is formed among the optical filter, the lens barrel and the stop part, a space capable of effectively sealing the glue is formed between the optical filter and the stop part, the contact area of the optical filter and the glue is increased by means of the glue dispensing groove, and the problem that due to the fact that the glue dispensing quantity is low or glue dispensing is improper, water enters the lens in the cleaning process can be avoided.

Description

Technical field [0001] The present invention relates to the field of optical technology, and more specifically, to an optical lens and an electronic device using the optical lens. Background technique [0002] In the manufacturing process of the optical lens, it is necessary to load the lens, the stopper, and the light-shielding film in the lens barrel in sequence. Among them, the packaging process of the imaging chip in the optical lens mainly includes a CSP (ChipSize Package) packaging process and a COB (ChiponBoand, chip-on-board) packaging process. Compared with the CSP packaging process, the COB packaging process has a lower packaging cost, so the COB packaging process is more widely used. [0003] Furthermore, the optical lens adopting the COB packaging process after loading is completed, such as figure 1 with figure 2 As shown, it is necessary to inject glue into the gap L between the stopper 100 and the filter 110 to prevent the filter 110 and other components from being ...
