Abstract

The invention provides an assembling process of a magnetron cathode assembly. The assembling process comprises the following steps of S1, pre-assembling a pre-assembled part and molds; S2, welding andmold removal; S3, leak detection; S4, installing a filament and an upper end cap, and welding and fixing the filament and the upper end cap; S5, filament carbonization; and S6, resistance detection and titanium powder coating; wherein the pre-assembled part comprises a lower end cap, a long lead, a reflecting plate, a K side tube, a solder plate, a support body and a terminal assembly, and the molds comprise an upper mold and a lower mold. By arranging the upper mold and the lower mold, the cathode assembly does not deform during welding, so that the structural precision of the cathode assembly is ensured, by arranging an upper clamp and a lower clamp of a leak detector, higher sensitivity and detection precision are achieved during the leak detection of the cathode assembly, by adoptinga cathode assembly assembling process formed by the molds, the assembling precision of the magnetron cathode assembly is ensured, and the product percent of pass is improved.

Description

Technical field[0001]The invention relates to the field of magnetrons for generating microwave equipment, in particular to an assembly process of a magnetron cathode assembly.Background technique[0002]A magnetron is an electric vacuum device used to generate microwave energy. It is essentially a diode placed in a constant magnetic field. The electrons in the tube interact with high-frequency electromagnetic fields under the control of a constant magnetic field and a constant electric field perpendicular to each other. , Convert the energy obtained from a constant electric field into microwave energy, so as to achieve the purpose of generating microwave energy. The magnetron is characterized by high power, high efficiency, low working voltage, small size, light weight and low cost.[0003]In the prior art, the magnetron mainly includes an anode assembly, a cathode assembly, an exhaust pipe assembly, etc., and the concentricity and vacuum degree of each component are important indicator...
