[0038] See also Figures 1 to 4, an embodiment of the present invention provides a method for processing an anode cylinder assembly 10 .

[0039] The anode cylinder assembly 10 includes an anode cylinder 12 and a plurality of vanes 14 . The plurality of vanes 14 are disposed in the anode cylinder 12 and are radially arranged around the axis of the anode cylinder 12 .

[0040] The processing method of the anode cylinder assembly 10 includes:

[0041] Step S101: forming a welding layer on the inner wall of the blade 14 and / or the anode cylinder 12;

[0042] Step S103: connecting the blade 14 to the inner wall of the anode cylinder 12 through the welding layer;

[0043] Step S105 : welding the anode cylinder assembly 10 so that the welding layer forms a connection layer 16 that fixes and connects the blades 14 and the inner wall of the anode cylinder 12 .

[0044] The processing method of the anode cylinder assembly 10 mentioned above, through the welding layer set on the blades 14 and / or the anode cylinder 12, enables the blades 14 and the anode cylinder 12 to be directly welded and fixed without the need for additional welding materials, thereby reducing the amount of precious metals in the welding materials and reducing the manufacturing cost of the anode cylinder assembly 10.

[0045] Specifically, a microwave oven (microwave oven / microwave) is a modern cooking appliance that uses microwaves to heat food. Microwaves are electromagnetic waves. A microwave oven is composed of a power supply, a magnetron 100, a control circuit, a cooking cavity, and other parts. The power supply provides a high voltage of about 4000 volts to the magnetron 100. Under the excitation of the power supply, the magnetron 100 continuously generates microwaves. The magnetron 100 is connected to the stirring antenna through a waveguide to transmit microwaves to the stirring antenna. Then, the stirring antenna emits microwaves to various places in the cooking cavity during rotation to heat the food in the cooking cavity.

[0046] Among them, the magnetron 100 is an important component for generating microwaves. The magnetron 100 is a vacuum electron tube for generating microwaves. The parts of the magnetron 100 are often made of precious metals or rare metals, and the manufacturing cost is very high.

[0047] With the increasing popularity of household microwave ovens, people's production and life have higher and higher demands for magnetrons 100, and the usage of magnetrons 100 is also increasing. Therefore, it is particularly important to reasonably reduce the manufacturing cost of magnetrons 100.

[0048] The anode cylinder assembly 10 of the magnetron 100 generally includes an anode cylinder 12 and a plurality of anode vanes 14 . The plurality of anode vanes 14 are welded to the inner wall of the anode cylinder 12 by means of a welding material having a high melting point.

[0049] In the related art, the anode cylinder assembly 10 is welded in a hydrogen furnace. First, a plurality of blades 14 are installed in the anode cylinder 12, and then a ring-shaped welding wire is placed above the blades 14. During the welding process, the ring-shaped welding wire melts in a high temperature environment, and the melted welding material flows into the gap between the blades 14 and the anode cylinder 12 by capillary action to achieve the purpose of welding.

[0050] During welding, part of the annular welding wire melts and flows into the gap between the blade 14 and the anode cylinder 12, and part of the welding material remains on the surface of the blade 14. Using the annular welding wire to weld the blade 14 and the anode cylinder 12 will waste a lot of welding material, and the welding material is generally a copper-silver alloy, in which the content of precious metal silver is about 70%. Therefore, using the annular welding wire for welding will waste a lot of precious metals, thereby increasing the manufacturing cost of the anode cylinder assembly 10.

[0051] Therefore, a processing method of an anode cylinder assembly 10 provided in an embodiment of the present invention uses welding material as a connecting layer 16, which is arranged between the blades 14 and the anode cylinder 12. During welding, the connecting layer 16 melts and fixes the blades 14 and the anode cylinder 12. No additional welding material is required, which can save a lot of precious metals in the welding material and simplify the steps of processing and assembling the anode cylinder assembly 10.

[0052] The connection layer 16 may be disposed on the inner side wall of the anode cylinder 12 or on the surface of the blade 14 connected to the anode cylinder 12. Alternatively, the connection layer 16 may be disposed on both the blade 14 and the inner side wall of the anode cylinder 12.

[0053] In some embodiments, the welding layer is formed on the inner wall of the vane 14 and / or the anode cylinder 12 by electroplating.

[0054] In this way, the ring-shaped welding wire used in welding can be eliminated to save the amount of precious metals in the welding material.

[0055] Specifically, when the welding material is electroplated on the surface of the blade 14 or the inner wall of the anode cylinder 12, precious metal silver can be used as the welding material. A layer of silver metal film is attached to the surface of the blade 14 or the inner wall of the anode cylinder 12 by electrolysis, which serves as the connecting layer 16. During welding, the connecting layer 16 formed by the silver metal film melts and fixes the blade 14 and the inner wall of the anode cylinder 12. When the welding material is electroplated on the inner wall of the blade 14 or the anode cylinder 12, a small amount of precious metal is required, and the surface of the inner wall of the blade 14 or the anode cylinder 12 can be evenly covered.

[0056] See also Figure 6 In some embodiments, the blade 14 includes a first end and a second end facing each other, and the welding layer is formed on the entire end surface of the second end by electroplating.

[0057] In this way, electroplating welding material on the contact surface between the blade 14 and the anode cylinder 12 can save welding material to a great extent on the one hand, and make the welding material evenly distributed on the contact surface between the blade 14 and the anode cylinder 12 on the other hand.

[0058] Specifically, the connection layer 16 is arranged on the contact surface of the blade 14 and the anode cylinder 12, and the welding material is electroplated in advance on the contact surface of the blade 14 and the anode cylinder 12, so that the welding material can be evenly distributed, and the welding material used is greatly reduced. While ensuring the welding connection effect, the amount of precious metal materials is saved, and the manufacturing cost of the anode cylinder assembly 10 is reduced.

[0059] It should be noted that the welding material may completely cover the surface of the blade 14 , or may be only partially electroplated on the contact surface between the blade 14 and the anode cylinder 12 .

[0060] See also Figure 5 In some embodiments, step S105 includes:

[0061] Step S1051: placing the anode cylinder assembly 10 in a hydrogen furnace;

[0062] Step S1053: welding the anode cylinder assembly 10 in the hydrogen furnace at a preset temperature.

[0063] In this way, the connection layer 16 between the blades 14 and the anode cylinder 12 can be melted to weld and fix the blades 14 and the anode cylinder 12 .

[0064] Specifically, welding the anode cylinder assembly 10 in a hydrogen furnace can achieve batch processing with high welding efficiency. At the same time, it is easy to control the temperature during welding, and the anode cylinder assembly 10 is heated evenly. After the connection layer 16 is melted, it can evenly fill the gap between the blade 14 and the anode cylinder 12, so that the welding effect is good.

[0065] In summary, the welding material is used as the connecting layer 16 and is arranged between the blades 14 and the anode cylinder 12. During welding, the connecting layer 16 melts and fixes the blades 14 and the anode cylinder 12. No additional welding material is required, which can save a lot of precious metals in the welding material and simplify the steps of processing and assembling the anode cylinder assembly 10.

[0066] An anode cylinder assembly 10 according to an embodiment of the present invention is manufactured by the machining method of the anode cylinder assembly 10 according to any one of the above embodiments.

[0067] The anode cylinder assembly 10 described above can directly weld and fix the blades 14 and / or the anode cylinder 12 by means of the connecting layer 16 provided on the blades 14 and / or the anode cylinder 12 without the need for additional welding materials, thereby reducing the amount of precious metals in the welding materials and lowering the manufacturing cost of the anode cylinder assembly 10 .

[0068] In certain embodiments, the anode cylinder assembly 10 includes an anode cylinder 12 and a plurality of blades 14, wherein the plurality of blades 14 are disposed in the anode cylinder 12 and are radially arranged around the axis of the anode cylinder 12, wherein one end of the blade 14 is welded and fixed to the inner wall of the anode cylinder 12, and the other end is suspended toward the axis of the anode cylinder 12, and the anode cylinder assembly 10 includes a connecting layer 16, wherein the connecting layer 16 connects one end of the blade 14 to the inner wall of the anode cylinder 12, and the connecting layer 16 is formed on one end of the blade 14 and / or the inner wall of the anode cylinder 12 by electroplating.

[0069] In this way, the connection layer 16 melts during welding, and the blades 14 and the anode cylinder 12 can be fixedly connected.

[0070] Specifically, Figure 3 and Figure 4 As shown, the anode cylinder assembly 10 includes an anode cylinder 12 and a plurality of blades 14. The anode cylinder 12 is in the shape of a cylinder with openings at both ends. The plurality of anode blades 14 are evenly distributed in the circumferential direction of the inner wall of the anode cylinder 12, and each anode blade 14 is arranged along the radial direction of the anode cylinder 12. A resonance cavity is formed between two connected anode blades 14 and the inner wall of the anode cylinder 12.

[0071] In some embodiments, the blade 14 includes a first end and a second end that are opposite to each other, the axis of the anode cylinder 12 at the first end is suspended, and the connection layer 16 is formed on the second end.

[0072] In this way, a large amount of precious metal materials used in welding can be saved, saving manufacturing costs.

[0073] Specifically, a layer of silver metal film is attached to the surface of the blade 14 by electrolysis, which serves as the connecting layer 16. The connecting layer 16 formed by the silver metal film melts during welding, and fixedly connects the blade 14 and the inner wall of the anode cylinder 12. Electroplating welding material on the blade 14 requires less precious metal, and the surface of the blade 14 can be evenly covered.

[0074] In other embodiments, when the welding material is electroplated on the surface of the blade 14 , the welding material may completely cover the surface of the blade 14 .

[0075] In summary, during the processing of the anode cylinder assembly 10 of the magnetron 100, the welding steps of the blade 14 and the anode cylinder 12 are improved, and the welding material is set on one end of the blade 14 and / or the inner wall of the anode cylinder 12. This can save the amount of precious metals in the welding material, while also ensuring the welding effect, and ultimately reducing the manufacturing cost of the magnetron 100.

[0077] See also Figure 3 and Figure 6 In some embodiments, the magnetron 100 further includes a first cross-linking ring 18 and a second cross-linking ring 20, the blade 14 is provided with a first mounting groove 22 and a second mounting groove 24, the first mounting groove 22 and the second mounting groove 24 are arranged on the blade 14 relative to each other along a first direction, the first cross-linking ring 18 is installed in the first mounting groove 22, and the second cross-linking ring 20 is installed in the second mounting groove 24.

[0078] In this way, electrical connection between the vanes 14 can be achieved, and a resonance cavity is formed between the anode cylinder 12 and the vanes 14 .

[0079] Specifically, as shown in the figure, the first direction is Figure 3 The blades 14 are installed alternately in the up-down direction, that is, the first mounting grooves 22 and the second mounting grooves 24 are arranged alternately, the first cross-linking ring 18 is fixedly connected to the first mounting groove 22 every other blade 14, and the second cross-linking ring 20 is fixedly connected to the second mounting groove 24 every other blade 14. In this way, the first cross-linking ring 18 is installed on the blade 14 through the first mounting groove 22, and the second cross-linking ring 20 is installed on the blade 14 through the second mounting groove 24. The first mounting groove 22 and the second mounting groove 24 can be used to fix and position the first cross-linking ring 18 and the second cross-linking ring 20 during installation, simplifying the installation steps.
