Fixing method and fixing device for flash lamp and optical lens

Abstract

The embodiment of the invention discloses a fixing method and a fixing device for a flash lamp and an optical lens. The method comprises the steps that a reinforcing plate is provided, a flexible circuit board is borne on the reinforcing plate, and one flash lamp is electrically connected on the flexible circuit board; multiple reinforcing plate positioning holes are formed on the peripheral edge of the reinforcing plate; one optical lens is provided, the light incident side of the optical lens is provided with light incident side positioning columns, and the light emergent side of the optical lens is provided with multiple light emergent side positioning columns; the light incident side positioning columns of the optical lens and the reinforcing plate positioning holes of the reinforcing plate are clamped so that the optical lens is enabled to be fixed at one side, which is close to the flash lamp, of the flexible circuit board; a terminal equipment shell is provided, and the terminal equipment shell is provided with shell positioning holes; and the light emergent side positioning columns of the optical lens and the shell positioning holes of the terminal equipment shell are clamped so that the optical lens is enabled to be fixed on the terminal equipment shell. With application of the fixing method and the fixing device for the flash lamp and the optical lens, the light supplementing effect of the flash lamp in terminal equipment can be enhanced.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a method and device for fixing a flash lamp and an optical lens. Background technique [0002] At present, the shooting devices of terminal devices such as mobile phones and tablet computers are generally equipped with flashlights. When taking pictures in low light conditions, it is generally necessary to turn on the flashlights to supplement the light in the shooting environment. When the flash is activated, the optical lens condenses and astigmatizes the light emitted by the flash, and evenly hits the light on the objects within the viewing range of the camera, so as to obtain a good shooting effect. In the prior art, generally, the flashlight is fixed on the PCB circuit board by welding, and the optical lens is fixed on the terminal equipment casing by means of double-sided adhesive tape, hot melt, etc., because it is easy to fix the optical lens and the terminal equipment ca...

Problems solved by technology

In the prior art, generally, the flashlight is fixed on the PCB circuit board by welding, and the optical lens is fixed on the terminal equipment casing by means of double-sided adhesive tape, hot melt, etc., because it is easy to fix the optical lens and the terminal equipment casing. The resulting error makes the deviation between the light-emitting center of the flash and the center of the optical lens often larger, resulting in poor fill light effect of the flash
