[0029] In order to make the above objectives, characteristics and advantages of the present application more apparent, comprehensible and easily understood, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0030] One of the core ideas of the embodiment of the present application is that an antenna reflector plate based on a brazing process comprises a first metal plate, a second metal plate and a third metal plate; the first metal plate is brazed to one side of the second metal plate; and one side of the second metal plate away from the first metal plate is brazed to one side of the third metal plate. The present application has simple structure, high manufacturing efficiency, and can effectively control the cost on the premise of ensuring the manufacturing quality in mass production, thereby reducing the cost of the antenna reflector plate.

[0031] REFERENCE Figures 1-2 , Figure 1 It is shown that a structure schematic diagram of an antenna reflector plate based on a brazing process, which can specifically comprise a first metal plate 1, a second metal plate 2 and a third metal plate 3; the first metal plate 1 is brazed to one side of the second metal plate 2, at this time, one side of the second metal plate 2 away from the first metal plate 1 is brazed to one side of the third metal plate 3.

[0032] It should be noted that the second metal plate 2 serves as the framework structure of the entire reflector plate, and plays a role in supporting and connecting the first metal plate 1 and the third metal plate 3; the third metal plate 3 plays a role in strengthening the rigidity of the entire connecting plate.

[0033] It should be additionally noted that the structure of the first metal plate 1 can be a planar structure or a U-shaped structure, etc.

[0034] When the structure of the first metal plate 1 can be a planar structure, and the number of the first metal plates 1 is two or more, at this time, one side of each two adjacent first metal plates 1 is brazed to the same side of the second metal plate 2; and a vertical plate is inserted between the side walls of each two adjacent first metal plates 1, and the vertical plate is brazed to the first metal plate 1, i.e. the vertical plate is brazed between the side walls.

[0035] When the structure of the first metal plate 1 is a U-shaped structure, the outer bottom of the first metal plate 1 is brazed to one side of the second metal plate 2, and the U-shaped plate is the main structure of the reflecting plate, and the U-shaped structure can strengthen the rigidity of the first metal plate 1. When the number of the first metal plate 1 is two or more, then the two adjacent first metal plates 1 are brazed by the outer side wall side by side, the outer bottom of the first metal plate 1 is brazed to the same side of the second metal plate 2, and the outer bottom of the first metal plate 1 is brazed to cover the side of the second metal plate 2. At the same time, in order to ensure the quality of brazing, the maximum gap between the two adjacent first metal plates 1 is less than 0.2mm.

[0036] In the embodiment, a fourth metal plate is also included, and the fourth metal plate is a U-shaped structure.

[0037] The total number of the first metal plate 1 and the fourth metal plate is two or more.

[0038] The outer side wall of the fourth metal plate is cross arranged and brazed to the outer side wall of the first metal plate 1.

[0039] The outer bottom of the fourth metal plate is brazed to the same side of the second metal plate 2 as the outer bottom of the first metal plate 1.

[0040] It should be noted that the outer side wall of the fourth metal plate is cross arranged and brazed to the outer side wall of the first metal plate 1, which means that under the premise that the fourth metal plate and the first metal plate 1 are both U-shaped structures, the outer side of the first metal plate 1 is brazed to the outer side of the fourth metal plate, and the other outer side of the fourth metal plate is brazed to the outer side of the other first metal plate 1, and the cross arrangement and brazing are continued in this way. At the same time, in order to ensure the quality of brazing, the maximum gap between the adjacent fourth metal plate and the first metal plate 1 is less than 0.2mm.

[0041] In another embodiment, when the structure of the first metal plate 1 is a U-shaped structure, and the first metal plate 1 is a metal plate with composite filler on one side, at this time the composite filler is located on the outer side wall and the outer bottom of the U-shaped structure of the first metal plate 1.

[0042] It should be noted that when the structure of the first metal plate 1 is not a U-shaped structure, but the first metal plate 1 is a metal plate with composite filler on one side, the side of the first metal plate 1 provided with the composite filler is brazed to one side of the second metal plate 2. At the same time, the third metal plate 3 can also be a metal plate 5 with composite filler 4 on one side, and the side of the second metal plate 2 away from the first metal plate 1 is brazed to the side of the third metal plate 3 provided with the composite filler 4.

[0043] In other embodiments, the first metal plate 1, the second metal plate 2, the third metal plate 3 and the fourth metal plate are all provided with holes, which are mainly connected with other large parts or other small parts through the matching connection of the through-hole bolts and the holes; meanwhile, the second metal plate 2 and the third metal plate 3 can both be flat plate structures.

[0044] Referring to Figure 3 , a step flow chart of an embodiment of a manufacturing method of an antenna reflector plate based on a brazing process is shown, which can specifically include the following steps:

[0045] S1, manufacturing a first metal plate 1;

[0046] S2, manufacturing a second metal plate 2;

[0047] S3, manufacturing a third metal plate 3;

[0048] S4, assembling and connecting the first metal plate 1, the second metal plate 2 and the third metal plate 3.

[0049] Specifically, in the step S1 of manufacturing the first metal plate 1, according to the processing requirements, the first metal raw plate is cut to obtain the required length and width;

[0050] It should be noted that when the first metal plate needs to be designed as a U-shaped structure, the first metal raw plate after cutting is heated and then bent, and the first metal raw plate is bent into a U-shaped structure, wherein the heating method can be that the first metal raw plate to be heated is inserted into the heating coil of the high-frequency heating device, and local heating is performed at the limited bending position. The U-shaped plate is the main structure of the reflector plate, and the U-shaped structure can increase the rigidity; the bent first metal raw plate is naturally cooled and punched, and the required hole size and quantity are obtained at the corresponding position, that is, the first metal plate 1 with a U-shaped structure is obtained.

[0051] When the first metal plate needs to be designed as a flat plate structure, the first metal raw plate after cutting is polished and polished, and then punched at the corresponding position to obtain the required hole size and quantity, that is, the first metal plate 1 with a flat plate structure is obtained.

[0052] In the step S2 of manufacturing the second metal plate 2, according to the processing requirements, the second metal raw plate is cut to obtain the required length and width; the second metal raw plate after cutting is punched to obtain the second metal plate 2;

[0053] In the step S3 of manufacturing the third metal plate 3, according to the processing requirements, the third metal raw plate is cut to obtain the required length and width; the third metal raw plate after cutting is punched to obtain the third metal plate 3;

[0054] In the step S4 of manufacturing the first metal plate 1, the first metal plate 1, the second metal plate 2 and the third metal plate 3 are combined and connected, and the connection mode is mainly brazing connection, that is, combined welding. Before combined welding, the first metal plate 1, the second metal plate 2 and the third metal plate 3 are assembled and fixed in position to form an antenna reflector plate frame prototype, and welding filler is placed at the assembly gap between the first metal plate 1 and the second metal plate 2 and at the assembly gap between the second metal plate 2 and the third metal plate 3. Then the antenna reflector plate frame prototype is placed into a brazing furnace for heating, the welding filler is filled into the gap between the metal plates after melting, and the brazing connection is completed.

[0055] It should be noted that when the first metal plate 1 is a planar structure, one side of the first metal plate 1 is brazed to one side of the second metal plate 2, and when the number of the first metal plates 1 is two or more, one side of each of the two adjacent first metal plates 1 is brazed to the same side of the second metal plate 2, and a vertical plate is inserted between the side walls of the two adjacent first metal plates 1, and the vertical plate is brazed to the first metal plate 1. The brazing connection here can be direct brazing with a welding gun, or the brazing filler is filled between the vertical plate and the side wall of the first metal plate 1, and then placed into a brazing furnace for brazing connection.

[0056] Moreover, it should be noted that the punching operation can be performed when the metal plate parts are manufactured, or the punching operation can be performed on the corresponding positions of the metal plates after the combined welding is completed.

[0057] At the same time, in order to ensure the connection quality, the maximum assembly gap between the first metal plate 1 and the second metal plate 2 is less than or equal to 0.2 mm, and the maximum assembly gap between the second metal plate 2 and the third metal plate 3 is less than or equal to 0.2 mm.

[0058] In addition, the assembly and fixation in step S4 refers to the assembly in position, and the metal plates are still loose. Only when the antenna reflector plate frame prototype is placed into a brazing furnace for heating, the brazing filler is dissolved and filled between the metal plates, and the brazing filler cools to fix the brazing connection of the metal plates, the metal plates are fixed in position.

[0059] In other embodiments, when the first metal plate 1 is a U-shaped structure and the number of the first metal plates 1 is two or more, the two adjacent first metal plates 1 are brazed through the outer side walls, and the outer bottom parts thereof are brazed to the same side of the second metal plate 2 during the combined connection. During the assembly and fixation, the brazing filler is placed between the two adjacent first metal plates 1, and the maximum gap of the outer side walls of the two adjacent first metal plates 1 is less than 0.2 mm.

[0060] Meanwhile, according to actual situation, the fourth metal plate can be provided. The fourth metal plate is in U-shaped structure, and the outer side wall of the fourth metal plate is cross-arranged and brazed with the outer side wall of the first metal plate 1. Here, it is meant that under the premise that the fourth metal plate and the first metal plate 1 are both in U-shaped structure and the total number of them is two or more, the outer side of the fourth metal plate is brazed with the outer side of the first metal plate 1, and the other outer side of the fourth metal plate is brazed with the outer side of another first metal plate 1, and so on. Meanwhile, in order to ensure the quality of brazing, brazing filler metal is placed between the two adjacent fourth metal plates and the first metal plate 1 when assembling and fixing, and the maximum gap between the adjacent fourth metal plate and the first metal plate 1 is less than 0.2 mm.

[0061] It should be noted that, in order to facilitate assembly and fixing, improve efficiency and ensure connection quality, the first metal plate 1 can be a composite metal plate, one side of which is a composite filler metal. In order to ensure the quality of connection, the thickness of the composite filler metal is less than or equal to 0.2 mm.

[0062] When the first metal plate 1 is in flat plate structure, the side provided with the composite filler metal is connected with one side of the second metal plate 2. In addition, according to actual situation, when the number of the first metal plate 1 is two or more, the side provided with the composite filler metal of the two adjacent first metal plates 1 is connected with the same side of the second metal plate 2, and a vertical plate is inserted between the side walls of the two adjacent first metal plates 1, and the vertical plate is brazed with the first metal plate 1. Here, the brazing can be directly brazed with a welding gun, or the brazing filler metal is filled between the vertical plate and the side wall of the first metal plate 1, and then put into the brazing furnace for brazing.

[0063] When the first metal plate 1 is in U-shaped structure, during the processing of the first metal plate 1, the side without the composite filler metal is subjected to U-shaped structure stamping, so that the side provided with the composite filler metal is exposed on the outer side and the outer bottom of the metal plate. At this time, the outer bottom provided with the composite filler metal is connected with the second metal plate 2.

[0064] In order to facilitate assembly and fixing and ensure the quality of connection, the third metal plate 3 also adopts a composite metal plate, which is a metal plate 5 provided with a composite filler metal 4 on one side. The composite filler metal 4 is connected with the side of the second metal plate 2 away from the first metal plate 1 during assembly and fixing. The thickness of the composite filler metal 4 is less than or equal to 0.2 mm.

[0065] In order to facilitate assembly and fixing and ensure the connection quality, the fourth metal plate can also be a composite metal plate, and one side of the metal plate is also provided with composite filler, wherein the thickness of the composite filler is less than or equal to 0.2 mm. During the processing of the fourth metal plate, the side without the composite filler is subjected to U-shaped structure stamping, so that the side with the composite filler is exposed to the outer side and the outer bottom of the metal plate; at this time, the outer bottom provided with the composite filler is connected with the second metal plate 2, and the outer side wall is also connected with the outer side wall of the first metal plate 1 of the U-shaped structure.

[0066] It should be noted that the material of the metal plate involved in the reflecting plate can be copper, silver, gold, aluminum, hard alloy, etc.; wherein due to the difference of the material of the metal plate, the filler and the composite filler involved are different, but one common point of the filler and the composite filler is that the melting point thereof is lower than that of the metal plate contacted in the welding process, and can be fused with the metal plate;

[0067] The holes in the metal plates are mainly connected with other large parts or small parts through the matching of the through-hole bolts and the holes;

[0068] At the same time, the second metal plate 2 and the third metal plate 3 are mostly in the form of a flat plate, because the second metal plate 2 serves as the framework structure of the whole reflecting plate and plays a role in supporting and connecting the first metal plate 1 and the third metal plate 3; the third metal plate 3 plays a role in strengthening the rigidity of the whole plate; the flat plate structure can make them better play the roles required.
