Description

Technical Field

[0001] This application relates to the field of microwave component packaging technology, and in particular to an adjustable multi-channel TR component laser sealing welding fixture. Background Technology

[0002] Currently, multi-channel TR modules generally adopt a split cover plate structure. Taking a 16-channel module as an example, it can be combined in the form of 2 channels / cover plate, 4 channels / cover plate, or 8 channels / cover plate.

[0003] In the welding and packaging process of microwave components, each cover plate must first be pressed evenly onto the surface of the box and then spot welded for positioning. After the spot welding is completed, the overall sealing welding is then performed.

[0004] If the clamping force is unevenly distributed during the spot welding stage, the local gap between the cover plate and the box will undergo slight deformation, thereby changing the electromagnetic boundary conditions of the microwave transmission path and directly causing the drift of key parameters such as standing wave and insertion loss.

[0005] Experiments show that the deformation cannot be fully recovered after subsequent sealing and welding, resulting in irreversible deterioration of the indicators that were qualified before packaging, and ultimately causing some performance aspects to fail to meet design requirements. Utility Model Content

The clamping components are used to contact the top of the cover plate of the microwave assembly and press the box of the microwave assembly onto the base through the cover plate of the microwave assembly.

[0008] Optionally, the adjustment frame includes a side frame and a top plate, wherein: The side frame is provided with a pair; The top plate is mounted on the side frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the adjustable horizontal spacing structure formed by the base and the adjustable side frame, and the longitudinal sliding positioning of the top plate in the limiting groove, the same welding fixture can be adapted to microwave components of different lengths, widths and heights, realizing that one set of fixtures is compatible with products of multiple sizes, reducing the manufacturing and storage costs of multiple sets of special fixtures. 2.

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0023] This application discloses an adjustable multi-channel TR component laser sealing welding fixture.

[0024] An adjustable multi-channel TR component laser sealing welding fixture includes a base 1, an adjustment frame 2, and a clamping component 3. The adjustment frame 2 is mounted on the base 1 and forms a placement area for placing a microwave component 4 between the adjustment frame 2 and the base 1. The clamping component 3 is mounted on the adjustment frame 2 and contacts the top of the cover plate 42 of the microwave component 4, and the cover plate 42 presses the box 41 of the microwave component 4 onto the base 1.

[0025] During the encapsulation and welding of microwave component 4, the housing 41 and cover plate 42 of microwave component 4 are placed in the placement area, with the cover plate 42 placed on the housing 41. The range of the placement area is adjusted according to the size of microwave component 4 to accommodate microwave components 4 of different sizes. Before welding the cover plate 42 of microwave component 4 onto the housing 41, the cover plate 42 is pressed onto the housing 41 by the clamping member 3. Then, spot welding is performed between the cover plate 42 and the housing 41, and between the cover plate 42 and the cover plate 42. After welding is completed, the spot-welded microwave component 4 is removed from the welding fixture for further sealing welding.

[0026] The same welding fixture can be used to place multiple microwave components 4 in batches and weld multiple microwave components 4.

[0027] The adjustment frame 2 includes a side frame 21 and a top plate 22. The side frames 21 are arranged parallel to the base 1, and both side frames 21 are fixedly installed on the base 1. The top plate 22 is installed on the side frames 21, and a placement area is formed between the top plate 22, the side frames 21 and the base 1. The clamping member 3 is installed on the top plate 22.

[0028] In order to facilitate the stable pressing of the cover plate 42 onto the box body 41, and also to facilitate the simultaneous placement of multiple microwave products of the same size, the top plate 22 is provided with multiple side frames 21 along its length.

[0029] The top plate 22 is located on the adjacent side frame 21. Each side frame 21 has a limiting groove 211 on its side that is close to each other. The length direction of the limiting groove 211 is consistent with the length direction of the side frame 21. The end of the top plate 22 is placed inside the limiting groove 211 and slides in cooperation with the limiting groove 211.

[0030] The staff adjusts the position of the top plate 22 in the limiting groove 211 according to the position of the cover plate 42, so as to adapt to the cover plate 42 in different positions.

[0031] Both ends of the top plate 22 are integrally formed with limit plates 221. The width of the limit plate 221 is greater than that of the top plate 22. The limit plate 221 is placed inside the limit groove 211 and slides with the limit groove 211. The large contact area between the limit plate 221 and the inner wall of the limit groove 211 enhances the stability of the limit plate 221 placed in the limit groove 211 and further improves the stability of the top plate 22.

[0032] To facilitate welding between adjacent cover plates 42, a certain gap is left between two adjacent top plates 22, and the gap is located above the contact surface of the two adjacent cover plates 42. When the limiting plate 221 moves inside the limiting groove 211, it can make two adjacent limiting plates 221 contact each other to position the top plate 22, form a gap between the two adjacent top plates 22, and make the gap between the two adjacent top plates 22 the same to facilitate welding.

[0033] The side frame 21 is provided with an opening 212 for microwave product cables to pass through, which improves the convenience of placing cables and reduces the interference of cables to the microwave product packaging process.

[0034] To accommodate microwave products of different sizes, the spacing between the two side frames 21 is adjustable. After the microwave product is placed on the base 1, the side frames 21 are moved to contact the microwave product, thereby changing the size of the placement area.

[0035] The base 1 is provided with a T-shaped groove 11, which runs through both sides of the base 1 and through the top of the base 1. A T-shaped bolt 12 is provided inside the groove 11. The bolt head of the bolt 12 is placed inside the groove 11 and slides with the groove 11. The bolt stalk of the bolt 12 runs through the side frame 21, and a nut 13 is threaded onto the bolt 12. The nut 13 is rotated and the side frame 21 is fixed to the base 1 by the nut 13.

[0036] The clamping element 3 is installed on the top plate 22. In order to facilitate the even pressing of the cover plate 42 onto the box body 41, multiple clamping elements 3 are provided along the length of the top plate 22.

[0037] The clamping component 3 includes a clamping rod 31 and a clamping block 32. The clamping rod 31 is perpendicular to the top plate 22 and passes through the top plate 22 and is threadedly connected to the top plate 22. The clamping block 32 is installed at the bottom end of the clamping rod 31. The operator rotates the clamping rod 31 to make the clamping block 32 press against the cover plate 42, and the limiting plate 221 is fixed in the limiting groove 211 through the top plate 22.

[0038] In order to reduce the excessive force of the clamping block 32 pressing the cover plate 42, the clamping block 32 is made of elastic material, and in this embodiment, it is made of rubber.

[0039] The clamping block 32 is shaped like a frustum, and the bottom diameter of the clamping block 32 is larger than the top diameter of the clamping block 32. The larger contact area between the clamping block 32 and the cover plate 42 improves the uniformity of the force on the cover plate 42.

[0040] The implementation principle of the adjustable multi-channel TR component laser sealing welding fixture in this application embodiment is as follows: The box 41 and cover plate 42 of the microwave component 4 are placed into the placement area formed by the base 1 and the adjustment frame 2. The placement area range is adjusted by moving the side frame 21 according to the size of the microwave component 4. Then, the limiting plate 221 at the end of the top plate 22 is slid along the limiting groove 211 of the side frame 21 to the top of the cover plate 42, so that the adjacent top plates 22 maintain an equal distance. The clamping rod 31 on the top plate 22 is rotated to make the rubber clamping block 32 evenly press the cover plate 42. Then, spot welding is performed on the contact surface between the cover plate 42 and the box 41 and the contact surface between adjacent cover plates 42 by the welding equipment. Finally, the microwave component 4 that has been spot welded is removed from the welding fixture for subsequent sealing welding. At the same time, the entire welding fixture can be placed in parallel and welded multiple microwave components 4 of the same size.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
