Optical assembly structure and its manufacturing method

Abstract

The present invention relates to an optical component structure and its production method. Said method includes the following steps: (a) fixing an illuminant component and a sensing component on a conducting supporting frame; (b) combining an aperture component with open pore on said conducting supporting frame, and making said open pore be correspondent to said sensing component; and (c) utilizing transparent protective component to fix and package said illuminant component and said sensing component and making them be integrally formed on said conducting supporting frame, and making the projected arc portion and circular projected portion which are respectively correspondent to said open pore and said illuminant component be extended.

Description

technical field [0001] The present invention relates to an optical component structure and a manufacturing method thereof, in particular to an optical component designed through the structural design and manufacturing method, which can be applied to any imaging system with a light source and a sensing component. Background technique [0002] Generally speaking, an optical system is composed of sensing components, light sources, and optical lenses; such as an optical mouse, the light generated by the light source is used to hit the surface of the object (such as: desktop or mouse pad, etc.), due to the sensed The surface is uneven, and the image on the surface of the object is imaged on the sensing component using the lens. When the mouse moves on the surface of the object, the image is quickly captured by the image recognition technology, and the obtained image is converted into movement data; that is, a certain The image captured at a time point is compared with the image c...

[0005] However, in the first and second known optical systems, the above-mentioned several components with different functions are combined into an optical system, and each component is manufactured by different processes, and then assembled, resulting in complicated and time-consuming manufacturing steps; and because each component There are different errors between them, especially the light-emitting sources 106a, 44b require higher assembly accuracy to achieve better imaging quality, however, the combination tolerance of the finished product is difficult to achieve accurate imaging quality; in addition, as the second known The optical system, in order to obtain the appropriate light type and direction, performs a series of reflection and refraction through the light pipe (Light Pipe) combined with layers of optical lenses, which is easy to cause light loss, so that the light efficiency cannot be improved; and as the second known optical system, the assembly steps of the lower cover 180b are likely to bring in dust particles to adhere to the transparent silica gel 190b, which will affect the imaging quality at the slightest level, and produce waste products at the worst level, increasing the production cost
