Problems solved by technology

Although this technical solution is theoretically feasible to prevent dust from polluting the image sensor, in fact, the glue layer can only prevent the dirt remaining under the image sensor from falling out, and the dirt hidden in the screw teeth of the lens barrel and lens base When the dust falls, it does not necessarily fall directly on the gel layer. It may also cause the image capture unit to be tilted during the transportation process, when it is installed on the electronic product, or when the user operates the electronic product. On the image sensor, in this way, it cannot achieve the purpose of preventing the image sensor from being polluted by dust, obviously, there is a big problem with practicality

Embodiment Construction

[0013] Hereinafter, a preferred embodiment of the present invention is given and further described in detail with reference to the accompanying drawings.

[0014] like figure 2 and image 3 As shown, an optical lens 10 with a dust-proof structure according to a preferred embodiment of the present invention can be assembled on an image sensing component 20 , and is composed of a lens base 12 and a lens barrel 14 .

[0015] The mirror base 12 has a hollow base body 22 , and a first connecting portion 24 is threaded, and is arranged outside the top end of the base body 22 .

[0016] The lens barrel 14 has a hollow cylinder 26, the inner upper end of the cylinder 26 is provided with two lenses 16, 18, a second connecting portion 28 is a screw thread, and is located inside the bottom of the cylinder 26, and a blocking portion 30 is A protrusion is located inside the second connecting portion 28 at the bottom of the barrel 26 and extends towards the mirror base 12 .

Abstract

The present invention discloses an optical lens with dust proof structure, which comprises a lens base and a lens tube. The lens tube is arranged on the lens base. A plurality of lenses are arranged in the lens tube. In addition, the end of the inside of the lens tube which is corresponded with the lens base, or the end of the inside of the lens base which is corresponded with the lens tube is provided with a barrier part. The barrier part isolates the connecting part of the lens tube and the lens base and the inner of the lens base. So dust falling in the inner of the lens base from the connecting part of the lens tube and the lens base is avoided.

Description

technical field [0001] The present invention relates to an optical lens, and more specifically refers to an optical lens with a dustproof structure. Background technique [0002] like figure 1 As shown, the known image capture unit 1 used in electronic products with camera functions (such as digital cameras, personal digital assistants PDA and mobile phones, etc.) is generally composed of an optical lens group 2 and an image sensor assembly (image sensor) ) 3, the image sensing component 3 is electrically connected to a flexible printed circuit board (Flexible Printing Circuit Board, FPCB) 4, the optical lens group 2 is fixed on the image sensing component 3, and has a holder ) 5, the image capture unit 1 is set on the bottom side of the mirror base 5, and a lens barrel (barrel) 6 is screwed on the mirror base 5, and a lens 7 is arranged inside it. The light reaches the image sensing component 3 through the lens 7 and the mirror base 5 to generate an image signal, and the ...
