Description

Technical Field

[0001] The utility model relates to the technical field of TR components, and particularly relates to a welding tooling for a molybdenum-copper carrier of a spaceborne TR component. Background Technique

[0002] The microwave T / R or TR (Transmitter and Receiver) component is also one of the most important components of an active phased array radar system. One end of it is connected to the antenna, and the other end is connected to the intermediate frequency processing unit to form a wireless transmission and reception system. Its function is to amplify, phase-shift, and attenuate signals, and its performance will directly affect the detection effect of the entire active phased array radar system.

[0003] At present, with the development of the high integration and modularization of active phased array radars, the requirements for the integration, miniaturization, and lightweight of T / R components, as well as the production capacity and performance of TR components, are getting higher and higher. Especially for spaceborne T / R components, the performance requirements are very strict. The welding penetration rate of the molybdenum-copper carrier and the ring isolator affects the heat dissipation, circuit crosstalk, and insertion loss during the operation of the power amplifier, directly reflects the grounding effect, and is an important index affecting the performance of T / R components.

[0004] To meet the requirements of the welding penetration rate of the molybdenum-copper carrier and the ring isolator, the existing welding method is usually to manually heat the heating table to 170°C, then place the housing on the hot table for preheating, and then use tweezers to hold a low-temperature solder paste (Sn55Pb44Bi1 solder paste, melting point 164°C) dipped in flux and place it on the welding area of the molybdenum-copper carrier and the ring isolator. Finally, place the molybdenum-copper carrier and the ring isolator above the solder paste and wait for the hot table to heat up. After the solder melts, rub the molybdenum-copper carrier and the ring isolator to complete the welding. During manual welding, due to the strong magnetism of the ring isolator itself, adjacent two ring isolators will attract each other, resulting in inability to weld. At the same time, when placing the molybdenum-copper carrier and the ring isolator, most are placed by the way of manual observation and parking, which is easy to produce placement deviation, resulting in a certain deviation in the positions of the molybdenum-copper carrier and the ring isolator after welding, and the welding penetration rate of the product cannot be guaranteed. In view of the above defects, it is necessary to design a welding tooling for a molybdenum-copper carrier of a spaceborne TR component. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 3 As shown, the present invention provides a technical solution: a molybdenum-copper carrier welding tool for a spaceborne TR component, including a base 1, a pressing plate 2, a pressing component 3 and a clamping component 4. A pressing plate 2 is arranged above the base 1, and two groups of pressing components 3 are arranged at intervals on the pressing plate 2. Each group of pressing components 3 includes two first pressing columns 31 and two second pressing columns 32. The two first pressing columns 31 are arranged side by side at intervals, and the two second pressing columns 32 are arranged side by side at intervals. Clamping components 4 are installed on both sides of the base 1.

[0027] In this embodiment, a placing groove 11 is opened at the top of the base 1, and limiting grooves 12 are opened on both sides of the placing groove 11. There are three limiting grooves 12, and the three limiting grooves 12 are evenly spaced. Three square grooves 13 are opened at intervals at the bottom of the placing groove 11. The base 1 is made of graphite material. Through the anti-fooling settings of the limiting grooves 12 and the square grooves 13, once the direction of the TR component 5 is placed incorrectly during the placement process of the TR component 5, the TR component 5 cannot be engaged with the placing groove 11, the limiting grooves 12 and the square grooves 13, so that the TR component 5 will not be installed reversely.

[0028] One end of the pressing plate 2 in this embodiment is provided with a plurality of arc-shaped grooves 21. The other end of the pressing plate 2 extends outwardly with a boss 22. Two groups of positioning holes are arranged at intervals in the middle of the pressing plate 2. Each group of positioning holes includes a first pressing post positioning hole 23 and a second pressing post positioning hole 24 located on one side of the first pressing post positioning hole 23. The cross-section of the first pressing post positioning hole 23 is T-shaped.

The cross-section of the second pressing post positioning hole 24 is L-shaped. There are two second pressing post positioning holes 24, and the two second pressing post positioning holes 24 are arranged side by side at intervals.

[0029] The first pressing post 31 in this embodiment is of an L-shaped structure and is made of stainless steel. The first pressing post 31 includes a first pressing post body 311 and a first convex block 312. One side of the first pressing post body 311 extends outwardly with a first convex block 312, and the first convex block 312 is integrally provided with the first pressing post body 311. Through the anti-fooling setting of the first pressing post body 311 and the first convex block 312, once the direction of the first pressing post 31 is placed wrongly during the placement process of the first pressing post 31, the first pressing post 31 cannot be engaged with the first pressing post positioning hole 23, so that the first pressing post 31 will not be installed reversely.

[0030] The second pressing post 32 in this embodiment is of a convex-shaped structure and is made of brass. Its brass has a heavy mass, so that the second pressing post 32 exerts a large pressure on the ring isolator, thereby avoiding problems such as poor penetration rate and position deviation of the ring isolator caused by insufficient pressure. Moreover, the two permanent magnets on the ring isolator have strong magnetism, and the second pressing post 32 is made of brass, which avoids strong magnetic interference on the ring isolator during the welding process. The second pressing post 32 includes a second pressing post body 321 and a second convex block 322. The middle of the second pressing post body 321 extends outwardly with a second convex block 322, and the second convex block 322 is integrally provided with the second pressing post body 321. Through the anti-fooling setting of the second pressing post body 321 and the second convex block 322, once the direction of the second pressing post 32 is placed wrongly during the placement process of the second pressing post 32, the second pressing post 32 cannot be engaged with the second pressing post positioning hole 24, so that the second pressing post 32 will not be installed reversely.

[0031] The clamping assembly 4 in this embodiment includes a clamping block 41, a spring 42, a screw 43 and a support column 44. The support column 44 is installed on the base 1. A clamping block 41 is rotatably arranged on the support column 44. A threaded hole 441 is formed at the top of the support column 44. The clamping block 41 includes a pressing block 411 and a rotating column 412. One end of the pressing block 411 is installed on the rotating column 412. The pressing block 411 and the rotating column 412 are of an integrated structure. A stepped hole 413 penetrating through the upper and lower end faces is formed in the clamping block 41. A screw 43 is arranged inside the stepped hole 413. The screw 43 passes through the stepped hole 413 and is screwed into the threaded hole 441 of the support column 44. A spring 42 is sleeved on the screw 43. One end of the spring 42 is fixedly connected to the head of the screw 43, and the other end of the spring 42 is fixedly connected to the bottom wall of the stepped hole 413.

[0032] The working principle of the present utility model:

[0033] Apply a soldering flux on the surface of the solder pad and also on the welding position of the TR assembly 5. After the soldering flux application is completed, place the TR assembly 5 in the placement groove 11 of the base 1, place the pressing plate 2 on the TR assembly 5, then pull the clamping block 41 upward to compress the spring 42, and then rotate the clamping block 41 so that the pressing block 411 on the clamping block 41 rotates above the pressing plate 2. Finally, release the clamping block 41. Under the action of the spring 42, drive the pressing block 411 of the clamping block 41 to move downward so that the pressing block 411 contacts and presses the pressing plate 2. After the pressing plate 2 is pressed tightly, the solder pad and the molybdenum copper sheet are sequentially placed into the welding position of the TR assembly 5 through the first pressing column positioning hole 23. Under the action of the first pressing column positioning hole 23, the solder pad and the molybdenum copper sheet can be positioned, which can well avoid the deviation of the positions of the solder pad and the molybdenum copper sheet and ensure the penetration rate of the product. The solder pad and the ring isolator are placed into the welding position of the TR assembly 5 through the second pressing column positioning hole 24. Under the action of the second pressing column positioning hole 24, the solder pad and the ring isolator can be positioned, which can well avoid the deviation of the positions of the solder pad and the ring isolator and ensure the penetration rate of the product. After the solder pad, the molybdenum copper sheet and the ring isolator are placed, place the first pressing column 31 and the second pressing column 32 on the first pressing column positioning hole 23 and the second pressing column positioning hole 24 respectively. The first pressing column 31 presses the solder pad and the molybdenum copper sheet, and the second pressing column 32 presses the solder pad and the ring isolator. Place the base 1 on the hot stage and wait for the hot stage to heat up. After the solder pad melts, the welding is completed.
