Problems solved by technology

The limitations of this assembly process are: use a tin spotting machine to spot tin on the cavity ribs. Although it prevents metal wires and shavings from falling into the cavity when threading the screw, it takes a long time to spot tin (depending on the complexity of the product structure, usually Dozens or hundreds of times the man-hours of the tin printing process); the accuracy of tin spotting by the tin spotting machine is poorly controllable, and tin cannot be applied quantitatively according to product requirements

Abstract

The invention provides a cavity filter cover plate tin printing and assembling method and auxiliary tooling. The method includes the following steps: (1) using a printing machine to print tin on the cover plate; (2) printing the tin-printed cover plate Transferred to the auxiliary tooling, the auxiliary tooling covers the tin-printing side of the cover plate, and the auxiliary tooling is provided with slots corresponding to the tin-printing path of the cover plate and openings corresponding to the screw holes on the cover plate. (3) Assemble the screws on the cover plate, the screws pass through the screw holes on the cover plate and the openings on the auxiliary tooling, clean the metal chips after assembly; (4) Remove the auxiliary tooling and tin the cover plate one side is welded to the cavity. The invention is aimed at the tin printing and assembly process of the cover plate. After the cover plate is tin printed, auxiliary tooling is used to protect the solder paste and support the cover plate to pass through the screw. , the generation of chips, to ensure product quality, reduce the risk of opening and rework.

Description

technical field [0001] The invention relates to the field of cavity filters, in particular to a tin-printing and assembling method for a cover plate of a cavity filter and auxiliary tooling. Background technique [0002] Cavity filter is a frequency selection device which is widely used in the field of communication. The cavity filter cavity and the cover plate need to be assembled and fixed. As a means of lightening and miniaturizing products, cover plate welding is more and more widely used. Application, limited by cavity structure, solder paste usually adopts printing process or spot tin process. [0003] For cover welding products, if there is a boss on the mounting surface of the cavity, the cavity rib printing process cannot be used, and the cover plate tin printing process can only be used or tin is dotted on the cavity rib. [0004] Among them, the tin on the cavity rib has extremely high requirements on the flatness of the cavity rib, and it takes a long time and h...
