An integrated welding device for microwave components

Abstract

The invention discloses an integrated welding device for a microwave component, which is used for welding the microwave component composed of a box body, a microwave substrate, a glass bead and a connector. The integrated welding device comprises a base, an upper pressing module, a left pressing module and a right pressing module. The left pressing module comprises a left pressing block, self-locking buckles and a spring needle; the right pressing module comprises a right pressing block, self-locking buckles and a spring needle; the upper pressing module comprises an upper pressing block, self-locking buckles and a spring needle. The self-locking buckles are mounted on the left pressing block, the right pressing block and the upper pressing block. Positioning pins are mounted on the base. The self-locking buckles are buckled with the positioning pins, so that the left pressing block, the right pressing block and the upper pressing block are respectively fixedly connected with the base. A spring needle hole is formed in each of the left pressing block, the right pressing block and the upper pressing block, and each of the spring needles is mounted on the corresponding spring needle hole, so that the left pressing block, the right pressing block and the upper pressing block compress the microwave component through the spring needles. The integrated welding device disclosed by the invention has the advantages of being high in welding efficiency, good in welding quality consistency, high in welding and positioning precision, free from product damage in the assembly process, good in reliability, simple to operate and the like.

Description

technical field [0001] The invention relates to an integrated welding device for electronic products, in particular to an integrated welding device for aerospace microwave components. Background technique [0002] The microwave component is the basis of the active phased array radar antenna and the core component of the active phased array radar. The consistency of the welding quality of the microwave component directly affects the overall machine index of the radar. An active phased array radar requires dozens or hundreds of components, or tens of thousands of microwave components. The welding of box body, microwave substrate, glass beads and connectors of microwave components is the basis of microwave component welding, and its welding quality directly affects the performance of microwave components. [0003] At present, the welding of microwave component boxes, microwave substrates, glass beads, and connectors is mainly carried out in the following steps. First, the micr...

AI Technical Summary

Problems solved by technology

[0004] 1. Solder paste needs to be applied before welding the glass beads and connectors. During the welding process, the solder is manually filled while heating. The welding efficiency is low. The amount of solder manually filled with solder cannot be controlled, and the welding quality is poor.

[0005] 2. It takes a long time to heat the glass beads and connectors one by one. When welding the glass beads, it is easy to cause remelting of the glass beads, connectors or substrates next to them. The welding process is prone to voids, poor penetration rate, and poor welding air tightness. The glass beads and connectors are not continuously pressurized, which may easily cause the glass beads or connectors to be skewed, and the welding positioning accuracy cannot be guaranteed

[0006] 3. When welding the side connector, the side is pressurized by rotation, such as patent CN 201988820 U, a welding tool for radio frequency connectors, and patent CN 201940768 U, a universal positioning tool for welding radio frequency connectors in microwave components. The process of rotation and pressure is easy to cause the surface gold plating layer of the connector and the box body to wear and tear. After the welding is completed, the gold plating layer wear interface is not infiltrated by the solder, and the appearance inspection cannot be found, which poses a serious safety hazard.

[0007] 4. Many screws need to be screwed during the pressurization process before welding, and the assembly efficiency is low. For example, the patent CN 203316963 U microwave component substrate reflow soldering elastic ballast device has no guidance during the ballast tooling positioning process during the assembly process, and the pressure is not high during the screw screwing process. Even, it is easy to cause the position of the substrate in the box to shift, affecting the welding quality
