Problems solved by technology
[0003] The current conventional connection technology is to use preformed solder to seal the lens and the support. In order to ensure the consistency of the focal length, the lens position is strictly required, and a large number of high-precision, high-temperature-resistant positioning fixtures are required to fix the support and the lens. Position, to ensure product accuracy, but the cost of accessories is high and easy to wear out; in addition, because the solder uses a preformed solder frame, it is easy to cause glass debris to fall on the lens during the distributing process, and the lens will adhere to the solder glass after high-temperature sintering. causing lens contamination

Abstract
The invention relates to a lens pipe cap preparation method; a lens and a pipe shell are sealed by an adhesive, the position of the lens is corrected by depending on the adhesive force of the adhesiveand through a pressing head of a machine to ensure the precision of a product; the bonding strength and the sealing property of a sealing place of the product are guaranteed by the adhesive. The preparation method is simple and easy to control, saves production costs, has the advantages of high precision and good quality, and solves the problem of lens pollution thoroughly.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a method for manufacturing a lens tube cap which is easy to manufacture and has low cost. Background technique [0002] In optical communication, optical transceiver devices usually use lenses as coupling elements for optical focusing, and at the same time, the lenses need to be installed and fixedly connected to the support to achieve the purpose of mechanical position fixation and hermetic sealing. The optical window packaging technology plays a vital role in the normal operation of optoelectronic devices, and the main influence on the optical window sealing technology is the connection technology between the support and the lens. [0003] The current conventional connection technology is to use preformed solder to seal the lens and the support. In order to ensure the consistency of the focal length, the lens position is strictly required, and a large number of hi...
