Abstract
The invention discloses a kind of high leakproofness optical window, is related to sensor technical field of sealing technology, including cover board and saturating window, and one surface of cover board is provided with a bottom plate；Bottom plate is provided with an opening；Cover board is provided with a groove；Groove is mutually communicated with opening；The aperture position of bottom plate fixes saturating window；Saturating window is weldingly fixed in groove by solder.The present invention by by optical window rest area using groove type design, ensure small product size reduce while, it is ensured that optical window high vacuum strength reliability, have eutectic weldering weld strength height, seal twice, greatly improve optical window air-tightness, leak rate is up to 5 × 10‑10Pa.m3/s。
Description
Technical field
The invention belongs to sensor technical field of sealing technology, more particularly to a kind of high leakproofness optical window.
Background technology
Sensor has been that Developing mainstream, most sensor are required for optical lens window, and many sensor cavities at present
Inside is high vacuum environment, therefore is had higher requirements to the leakproofness and intensity of optical window.And problem existing in the prior art is
The sealing performance of optical window is not high, saturating window and cover board adhesive strength is not high.So as to influence product production efficiency and product it is whole
Body performance, it is the key point that existing sensor enterprise enhances product performance to seek to design a kind of high reliability optical window.
The content of the invention
It is an object of the invention to provide a kind of high leakproofness optical window, by the way that optical window rest area is designed using groove type,
While ensureing that small product size reduces, it is ensured that optical window seals, greatly improve optical window gas in the strength reliability of high vacuum twice
Close property, leak rate is up to 5 × 10-10Pa.m3/ s, the sealing performance that solves existing optical window is high, saturating window and cover board adhesive strength
The problems such as not high.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of high leakproofness optical window, including cover board and saturating window, one surface of cover board are provided with a bottom plate；Institute
State bottom plate and be provided with an opening；The cover board is provided with a groove；The groove is mutually communicated with opening；The aperture position of the bottom plate
Fixed saturating window；The window is weldingly fixed in groove by solder.
Further, following sealing technology is further included：
Step 1, solder is placed between saturating window and cover board, makes its fastening using eutectic welding；
Step 2, eutectic welding terminate, and in saturating window and cover sidewall crack area filling fluid sealant, carry out secondary seal.
The invention has the advantages that：
1st, the present invention is by the way that optical window rest area is designed using groove type, while ensureing that small product size reduces, it is ensured that
Strength reliability of the optical window in high vacuum.
2nd, solder is seated to cover board encapsulation region by the present invention in process of production, then optical window is positioned on solder.Altogether
After crystalline substance welding, in saturating window and cover sidewall crack area filling fluid sealant, to product secondary seal.
3rd, have eutectic weldering weld strength high, seal twice, greatly improve optical window air-tightness, leak rate is up to 5 × 10- 10Pa.m3/s。
Certainly, implement any of the products of the present invention and do not necessarily require achieving all the advantages described above at the same time.
