[0006] 3. Curve forming: bend the metal plate to form the required antenna shape. This step usually requires the use of special mechanical equipment, such as bending machines, press machines, etc.

[0007] 4. Welding: The metal plates that have been formed into curves are welded to form the structure of the antenna. The welding process can be manual welding, automatic welding by welding robots, etc.

[0008] 5. Surface treatment: The welded antenna is subjected to surface treatment such as spraying, chrome plating, etc. to improve the corrosion resistance and aesthetics of the antenna.

[0009] 6. Electrical characteristics test: Conduct electrical characteristics test on the antenna after surface treatment to ensure that the performance of the antenna meets the design requirements.

[0010] 7. Assembly and debugging: Assemble the antenna that has passed the electrical test, such as installing the antenna base, adjusting the antenna angle, etc.

[0011] 8. Packaging and delivery: After completing the assembly and debugging of the antenna, package the antenna for easy transportation and storage.

[0043] The utility model forms a limiting area 107 between the movable frame 102 and the guide plate 104 to achieve the placement of the composite plate 109; since the limiting area 107 is formed between the movable frame 102 and the guide plate 104, and the position of the movable frame 102 is adjustable under the action of the adjustment unit 106, the depth of the limiting area 107 can be adjusted; in actual use, the composite plate 109 is placed on the movable frame, and the composite plate 109 is limited under the action of the guide plate 104, and the welding filler is laid after the composite plate 109 is placed, and then the position of the movable frame 102 is adjusted, and then the composite plate 109 is placed and the welding filler is laid in turn, and the whole process can achieve the limitation of the composite plate 109; after the placement is completed, the composite plate 109 is welded into a whole by side spot welding, and then the whole is vacuum brazed; in actual use, the utility model can achieve the positioning of the composite plate 109, avoid the misalignment of the solder during laying, and improve the qualified rate of the product.

[0044] Furthermore, a guide surface is provided on the inner side of the guide frame 105 , and the provided guide slope can play a guiding role, making the placement of the composite board 109 smoother.

[0045] Among them, the adjustment unit 106 includes a screw 110, an adjustment rod 111 and a transmission mechanism. A threaded hole is provided on the platform 101. After the screw 110 is matched with the threaded hole, the upper end is rotatably connected to the bottom of the moving frame 102, and the lower end is connected to one end of the adjustment rod 111 through the transmission mechanism. The adjustment rod 111 is slidably installed on the side of the platform 101 through the slider 113, and the adjustment rod 111 is rotatably connected to the slider 113.

[0047] When in use, it is necessary to rotate the adjusting rod 111 under the action of the transmission mechanism to realize the rotation of the screw 110. Since the screw 110 is rotatably connected to the moving frame 102, the screw 110 will move vertically when it rotates, thereby realizing the adjustment of the height of the moving frame; similarly, since the adjusting rod 111 is slidably installed on the platform 101 through the slider 113, when the screw 110 moves, the adjusting rod 111 will also move with it.

The pressurizing mechanism 117 includes a support plate 118, a telescopic rod 119, and a pressing plate 112. The support plate 118 is used to be installed above the platform 101, and the pressing plate 112 is connected to the support plate 118 through the telescopic rod 119. After the telescopic rod 119 is extended or shortened, the pressing plate 112 is moved closer to or away from the platform 101, thereby achieving the pressing of the composite plate 109. When the side spot welding of the composite plate 109 is performed, the welding effect can be improved by pressing, and the composite plate 109 is more closely contacted, thereby improving the welding quality during the final brazing.
