Problems solved by technology

However, this method of using glue to bond the fixed glass sheet 161 to the housing opening 12 needs to be heated and baked, and the glass sheet 161 needs additional processing to meet the ideal optical requirements, and its production cycle is relatively long. The process is cumbersome and mass production cannot be realized, so the cost of this packaging method is high; and there may be glue over...

Example Embodiment

[0017] The optical device packaging cover and the manufacturing method thereof of the present invention include the steps of providing a housing and an optical lens (detailed later), please refer to figure 2 and Figure 6 As shown, the optical packaging cover 40 includes a housing 20 and an optical lens 31. The housing 20 has a flat top 21 and an annular bottom plate 22, and the housing 20 is integrally formed and substantially shaped like a pot. A through optical lens mounting portion 23 is opened on the flat top 21, and the optical lens mounting portion 23 includes a transparent opening 231 and a first-rate crossing 232. In addition, the annular bottom plate 22 is a brim-shaped annular bottom plate extending from the bottom end of the housing 20 along the edge of the housing, so that the packaging cover is connected to the base (not shown) on which the optical device is placed when the optical device (not shown) is packaged. ) Can work closely together. The housing 20 of the packaging cover can be stamped from metal material or molded by plastic.
[0018] Please refer to image 3 and Figure 4 Shown, is figure 2 The top view of the housing of the optical device packaging cover and its cross-sectional view. The edge of the light-transmitting opening 231 has a continuous rib 24. The flow passage opening 232 is an opening that passes through the light-transmitting opening 231. The rib 24 extends from the edge of the light-transmitting opening 231 to the flow passage opening 232 to form a Continuous convex ring.
[0019] Please refer to Figure 5 and Figure 6 Shown are a perspective view and a cross-sectional view of the optical device packaging cover 40 of the present invention. The optical lens 31 of the packaging cover 40 is positioned on the optical lens mounting portion 23 of the housing 20. The optical lens 31 is made of optical lens material such as transparent optical The plastic material is molded in the optical lens mounting portion 23 by an injection molding process, such as insert molding, and the convex ribs 24 of the optical lens mounting portion 23 are embedded and fixed with the flat top 21. The optical lens 31 is embedded in the flat top 21 of the housing 20 to form a light-transmitting window, which realizes the sealing and light-transmitting effects of the packaging cover 40.
[0020] The manufacturing method of the optical device packaging cover 40 of the present invention mainly includes the following steps: first, a housing 20 with a flat top 21 is provided. The housing 20 can be integrally formed by metal stamping or plastic molding, and the flat top 21 is provided with The optical lens mounting portion 23 is formed by the intersecting light-transmitting opening 231 and the flow passage opening 232. The light-transmitting opening 231 is provided with a rib 24, and the rib 24 extends from the edge of the light transmission opening 231 to the flow passage opening 232. A continuous convex ring is formed; then, a mold is provided, and the housing 20 is placed in it; an optical lens material such as a transparent optical plastic material is provided, the optical lens material is preheated and dried, and then heated to a certain viscosity, In-mold molding is used to inject the optical lens material into the closed cavity through the nozzle of the mold, and guide it to the optical lens mounting portion 23 through the runner port 232 until it is filled; after cooling and solidification, the mold is opened and taken out. The optical device package cover 40.
[0021] Please refer to Figure 7 , Is a cross-sectional view of another embodiment of the optical device packaging cover. Compared with the first embodiment, the rib 24 is replaced by an inner groove 24', and the optical lens 31' and the inner groove formed by the in-mold molding process The 24' phase is inserted into the card so as to be better held on the flat top 21 of the housing.
[0022] The transparent opening of the flat top of the housing of the optical device packaging cover of the present invention can be provided with multiple ridges or grooves, and the flow channel opening that passes through the transparent opening can be a shallow groove that does not penetrate the flat top of the housing.
[0023] The optical device packaging cover of the present invention can be used for packaging semiconductor laser diodes, light detection diodes, optical transceiver modules and the like.
