[0039] See also Figures 1 to 4The embodiment of the present invention provides a method for processing an anode assembly 10 for a magnetron 100. The anode assembly 10 includes an anode cylinder 12, a cross-linking ring, and a plurality of blades 14. Each blade 14 includes a first welding area 17. The blade 14 is provided with a mounting groove. The first welding area 17 is arranged in the mounting groove. The processing method of the anode assembly 10 includes:

[0040] Step S101: forming a welding layer in the first welding area 17;

[0041] Step S103: connecting the blades 14 to the cross-linked rings through a welding layer;

[0042] Step S105: welding the anode assembly 10 so that the welding layer forms a connection layer 16 that fixes and connects the blades 14 and the cross-linking rings.

[0043] The processing method of the anode assembly 10 sets a welding layer in the first welding area 17 of the blade 14 to fix the blade 14 to the cross-linking ring. There is no need to set a welding layer on the cross-linking ring as a whole, which reduces the amount of precious metal used in the processing, thereby reducing the manufacturing cost of the magnetron 100.

[0044] 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 the rotation process to heat the food in the cooking cavity.

[0045] 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.

[0046] 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.

[0047] The anode assembly 10 of the magnetron 100 includes an anode cylinder 12 , a cross-linking ring and a plurality of vanes 14 . The plurality of vanes 14 are disposed in the anode cylinder 12 and radially arranged around the axis of the anode cylinder 12 . The cross-linking ring is fixedly connected to the vanes 14 .

[0048] In the related art, it is generally necessary to electroplate the entire cross-linking ring with precious metal silver and then weld it to the blades 14 . The electroplated silver melts at a high temperature to fix the cross-linking ring and the blades 14 together.

[0049] However, the contact area between the cross-linking ring and the blades 14 is relatively small, and electroplating the entire cross-linking ring will waste a large amount of welding materials, thereby increasing the production cost of the magnetron 100 .

[0050] The embodiment of the present invention provides a method for processing an anode assembly 10 , in which a welding layer is provided on the blade 14 . When the anode assembly 10 is welded, the welding layer melts to fix the blade 14 and the cross-linking ring.

[0051] In some embodiments, the blade 14 includes a first end and a second end. The first end of the blade 14 is fixedly connected to the inner side wall of the anode cylinder 12, the second end of the blade 14 faces the axis and is suspended, and the cross-linking ring is fixedly connected to the blade 14 at the second end of the blade 14.

[0052] In one embodiment, when the blade 14 and the anode cylinder 12 are welded together, the processing method includes:

[0053] Step S201: forming a welding layer on the inner wall of the blade 14 and / or the anode cylinder 12;

[0054] Step S203: connecting the blade 14 to the inner wall of the anode cylinder 12 through the welding layer;

[0055] Step S205 : 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 .

[0056] By providing a welding layer on the blade 14 and / or the anode cylinder 12 , the blade 14 and the anode cylinder 12 can be directly welded and fixed without additional welding materials, thereby reducing the amount of precious metals in the welding materials and reducing the manufacturing cost of the magnetron 100 .

[0057] In one embodiment, the blade 14 further comprises a second welding area 19, and the first welding area 17 is disposed in the mounting groove for welding the fixed blade 14 and the cross-linking ring. The second welding area 19 is disposed on the end surface of the first end of the blade for welding the fixed blade 14 and the anode cylinder 12.

[0058] In this way, the first welding region 17 and the second welding region 19 are arranged on the blade 14 , and a welding layer is arranged on the first welding region 17 and the second welding region 19 .

[0059] The welding layer melts and fixes the blades 14 and the anode cylinder 12 and the interlocking ring, which can save a lot of precious metals in the welding materials and simplify the steps of processing and assembling the anode assembly 10.

[0060] In some embodiments, the welding layer is formed on the first welding region 17 by electroplating.

[0061] In this way, a small amount of welding material can be used and the welding layer can be evenly distributed on the blade 14 .

[0062] Specifically, when the welding material is electroplated on the surface of the blade 14, 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 by electrolysis, which serves as the connecting layer 16. During welding, the welding layer formed by the silver metal film melts, and the blade 14 and the cross-linking ring are fixedly connected. When the welding material is electroplated on the blade 14, the amount of precious metal required is small, and the surface of the blade 14 can be evenly covered.

[0063] In some embodiments, the mounting groove includes a first mounting groove 22 and a second mounting groove 24 on opposite sides along a first direction, the cross-linking ring includes a first cross-linking ring 18 and a second cross-linking ring 20, the first cross-linking ring 18 is installed in the first mounting groove 22, the second cross-linking ring 20 is installed in the second mounting groove 24, and the first welding area 17 includes the groove walls of the first mounting groove 22 and the second mounting groove 24.

[0064] In this way, welding materials can be saved to a great extent.

[0065] Specifically, the blade 14 is provided with a first mounting groove 22 and a second mounting groove 24 on opposite sides along the first direction. Figure 3 and Figure 7 As shown, the first direction is Figure 3 The outer side wall of the first cross-linking ring 18 contacts the groove wall of the first installation groove 22, and the outer side wall of the second cross-linking ring 20 contacts the groove wall of the second installation groove 24. The welding layer is arranged in the groove walls of the first installation groove 22 and the second installation groove 24, and the contact surface between the first installation groove 22 and the first cross-linking ring 18 and the contact surface between the second installation groove 24 and the second cross-linking ring 20 can be fixedly connected. At the same time, the amount of welding material used in electroplating can be significantly reduced, thereby reducing the cost of the magnetron 100.

[0066] The first welding area 17 includes groove walls of the first mounting groove 22 and the second mounting groove 24. The groove walls include side walls and a bottom wall.

[0067] In one embodiment, the first welding region 17 may be separately disposed on the side walls of the first mounting groove 22 and the second mounting groove 24 .

[0068] In one embodiment, the first welding area 17 may be disposed on the bottom walls of the first mounting groove 22 and the second mounting groove 24 .

[0069] In one embodiment, the first welding area 17 may also be disposed on the side walls and the bottom walls of the first mounting groove 22 and the second mounting groove 24 at the same time.

[0070] See also Figure 5 In some embodiments, step S105 includes:

[0071] Step S1051: placing the anode assembly 10 in a hydrogen furnace;

[0072] Step S1053: welding the anode assembly 10 in the hydrogen furnace at a preset temperature to form a connection layer 16 that fixes and connects the blades 14 and the cross-linking rings.

[0073] In this way, the connection layer 16 can be melted to weld the stationary blade 14 and the first and second interlocking rings 18 and 20 .

[0074] Specifically, welding the anode 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 assembly 10 is heated evenly. After the connection layer 16 is melted, it can evenly fill the blade 14 and the connection surface between the first cross-linking ring 18 and the second cross-linking ring 20, so that the welding effect is good.

[0075] In summary, the welding layer is set on the blade 14 to fix the connection surface between the blade 14 and the first cross-link ring 18 and the second cross-link ring 20. There is no need to electroplate the outer surface of the first cross-link ring 18 and the second cross-link ring 20, which can save a lot of precious metals in the welding material and simplify the steps of processing and assembling the anode assembly 10.

[0076] An anode assembly 10 according to an embodiment of the present invention is manufactured by the processing method of the anode assembly 10 according to any one of the above embodiments.

[0077] In some embodiments, the anode assembly 10 includes an anode cylinder 12 and a plurality of blades 14. The plurality of blades 14 are disposed in the anode cylinder 12 and are radially arranged around the axis of the anode cylinder 12. One end of the blade 14 is welded and fixedly connected to the inner wall of the anode cylinder 12, and the other end is suspended toward the axis of the anode cylinder 12.

[0078] In this way, the connection layer 16 melts during welding, and the blades 14 and the anode cylinder 12 can be fixedly connected.

[0079] Specifically, Figure 3 and Figure 4As shown, the anode 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.

[0080] In some embodiments, the blade 14 is provided with a first mounting groove 22 and a second mounting groove 24 on opposite sides along the first direction, and the cross-linking ring includes a first cross-linking ring 18 and a second cross-linking ring 20. 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.

[0081] 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 .

[0082] Specifically, Figure 3 , Figure 6 and Figure 7 As shown, 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.

[0083] In some embodiments, the first mounting groove 22 includes a first side wall 28 and a first bottom wall 30, the outer side wall of the first cross-link ring 18 is fixedly connected to the first bottom wall 30 and / or the first side wall 28, and the bottom surface of the first cross-link ring 18 is in contact with the first bottom wall 30, and the second mounting groove 24 includes a second side wall 34 and a second bottom wall 36, the outer side wall of the second cross-link ring 20 is fixedly connected to the second bottom wall 36 and / or the second side wall 34, and the top surface of the second cross-link ring 20 is in contact with the second bottom wall 36.

[0084] In this way, the first bottom wall and the second bottom wall can play a limiting role in installing the first interlocking ring 18 and the second interlocking ring 20, thereby improving the assembly efficiency, and can also play a fixing role.

[0085] Specifically, Figure 7As shown, the first installation groove 22 includes a first side wall 28 and a first bottom wall 30. The first bottom wall 30 can fix the first cross-linking ring 18 and also limit the installation position of the first cross-linking ring 18. The second installation groove 24 includes a second side wall 34 and a second bottom wall 36. The second bottom wall 36 can fix the second cross-linking ring 20 and also limit the installation position of the second cross-linking ring 20.

[0087] In this way, the connection effect between the cross-linking ring and the blades 14 can be ensured, and the amount of electroplating material used to form the connection layer 16 can be significantly reduced, so as to achieve the purpose of reducing the manufacturing cost of the magnetron 100.
