[0037] The following will describe in detail the specific implementation manners of the present disclosure in conjunction with the accompanying drawings.
[0038] In the current power board soldering process, the power board and the signal board are connected together through T-shaped pins. When soldering the T-shaped pins, the T-shaped pins are first placed in the mounting holes of the power board and then soldered. When soldering the T-shaped board onto the power board, the position of the pre-placed T-shaped pins will move during the solidification of the solder. Therefore, by providing a fixing plate, the effect of the accuracy of the soldering position of the T-shaped pins can be achieved.
[0039] Figure 1 Shows a schematic structural diagram of a tooling 10 for mounting a T-shaped pin on a power board according to an embodiment of the present disclosure. As Figure 1 shown, the tooling for mounting a T-shaped pin on a power board includes a power board 100, a T-shaped pin 200, and a fixing board 300.
[0040] The power board 100 has mounting holes 101 for mounting the T-shaped pin 200, and after the T-shaped pin 200 is mounted in the mounting holes 101, it is welded. The fixing board 300 has positioning holes so that the T-shaped pin 200 can be disposed in the positioning holes 301, thereby ensuring that the height after welding remains consistent. Among them, the positions of the positioning holes 301 and the mounting holes 101 correspond to each other, so that the positional accuracy and perpendicularity of the T-shaped pin 200 after welding are always consistent. Specifically, in combination with Figure 3 the shown T-shaped pin 200, which includes a first end 201 and a second end 202 (regarding its specific structure, it will be described later in combination with Figure 3 ), the first end 201 is disposed in the positioning hole 301, and the power board 100 is buckled on the fixing board 300 provided with the T-shaped pin 200, so that the second end 202 of the T-shaped pin 200 is disposed in the mounting hole 101.
[0041] Through the above tooling including the power board 100, the T-shaped pin 200, and the fixing board 300, the fixing board 300 provided by the present disclosure can provide fixation during the welding of the T-shaped pin 200 and the power board 100, avoiding the movement of the position of the T-shaped pin 200 during the solidification of the solder, and greatly improving the accuracy of the welding position of the T-shaped pin 200.
[0042] Figure 2 Shows a cross-sectional view of a tooling 20 for mounting a T-shaped pin on a power board according to an embodiment of the present disclosure. As Figure 2 shown, the tooling for mounting a T-shaped pin on a power board includes a power board 100, a T-shaped pin 200, a fixing board 300, a connecting component 400, and a locking component 500. It can be understood that those skilled in the art can understand the power board 100, the T-shaped pin 200, and the fixing board 300 according to the disclosure of the present disclosure, that is, Figure 1 the power board 100, the T-shaped pin 200, and the fixing board 300 shown in
[0043] In one embodiment, the connecting component 400 is used to connect the power board 100 and the fixing board 300. The power board 100 includes a second connecting hole 102, and the fixing board 300 includes a first connecting hole 302. The first connecting hole 302 and the second connecting hole 102 connect the connecting component 400 for connecting the fixing board 300 and the power board 100. The locking component 500 is used to lock when the connecting component 400 connects the fixing board 300 and the power board 100 through the first connecting hole 302 and the second connecting hole 102. In addition, the fixing board 300 is further provided with a welding position hole 303, which is used to observe the state of the solder when the T-shaped pins 200 are welded to the power board 100, and to facilitate smoothly touching the position to be welded when welding the T-shaped pins 200 and the power board 100.
[0044] Specifically, the connecting component 400 can be any device capable of connecting the power board 100 and the fixing board 300, including but not limited to connecting pins, such as cylindrical pins, conical pins, and special-shaped pins, etc. The embodiments of the present disclosure do not limit this.

[0045] Specifically, the positioning hole 301 opened on the fixing board 300 can be any hole capable of keeping the T-shaped pins 200 fixed and at the same height. For example, the positioning hole 301 can be any hole with a larger aperture size at the end face close to the power board 100 than at the end face far from the power board 100, so that the T-shaped pins 200 can be limited without penetrating the positioning hole 301, thereby ensuring that the heights of the T-shaped pins 200 are consistent after welding. The embodiments of the present disclosure do not limit the positioning hole 301. Preferably, the positioning hole 301 can be a "convex"-shaped hole, with a larger aperture size at the end face close to the power board 100 than at the end face far from the power board 100, and the aperture size of the end face close to the power board 100 is adapted to the cross-sectional size of the T-shaped pins 200, so that the T-shaped pins 200 can be inserted into the positioning hole 301 to ensure that the heights of the T-shaped pins 200 are consistent after welding.
[0046] Specifically, the welding position hole 303 provided on the fixing board 300 can be any hole capable of observing the state of the solder when the T-shaped pins 200 are welded to the power board 100. The embodiments of the present disclosure do not limit this. Preferably, the welding position hole 303 is in an irregular shape as a whole, and it can match the position of the mounting hole 101 opened on the power board 100, so as to observe the state of the solder when the T-shaped pins 200 are welded to the power board 100, and to facilitate smoothly touching the position to be welded when welding the T-shaped pins 200 and the power board 100.

In combination with Figure 1 and Figure 3 , the first end 201 of the T-shaped pin 200 is the needle body, which is arranged in the positioning hole 301 to ensure that the height of the T-shaped pin 200 is consistent after welding. The second end 202 of the T-shaped pin 200 is the needle handle, which is arranged in the mounting hole 101. Preferably, the T-shaped pin 200 is integrally in a "T" shape, and its first end 201 can be inserted into the positioning hole 301 to limit the T-shaped pin. The second end 202 is installed in the mounting hole 101 and is welded to the power board 100.
[0049] Based on the above-mentioned tooling, the fixing plate 300 can be set at the relative position of the power board 100. In terms of materials, the fixing plate 300 of the present disclosure can be an aluminum plate, and its thickness can be 1-4 mm.

[0053] In step S430, the power board is buckled on the fixing board provided with the T-shaped pin, so that the second end of the T-shaped pin is set in the mounting hole. In one example, the second end of the T-shaped pin can be the needle body, which is set in the mounting hole. In another example, the second end of the T-shaped pin can also be the needle handle, which is set in the mounting hole to weld the T-shaped pin and the power board together.
[0054] Thus, by providing the fixing board, the solution provided by the embodiments of the present disclosure can improve the accuracy of the welding position of the T-shaped pin. The fixing board can provide fixation during the welding of the T-shaped pin and the power board, avoiding the position movement of the T-shaped pin during the solidification of the solder. Further, the fixing board has positioning holes, which can meet the requirements for fixing the T-shaped pin and accurately welding it, greatly improving the accuracy of the welding position of the T-shaped pin.

The fixing board includes a first connection hole, and the power board includes a second connection hole. It can be understood that the power board, the T-shaped pin, and the fixing board are also the Figure 4 shown power board, T-shaped pin, and fixing board. Therefore, the descriptions of the power board, the T-shaped pin, and the fixing board above also apply to the following. In one example, the connecting component can be the Figure 1 shown connecting component 400, and the locking component can be the Figure 1 shown locking component 500.

Preferably, the locking component can be a locking screw. Further, the locking component can pass through the first connecting hole and the second connecting hole into the connecting component to lock it. After locking the fixing plate and the power board, the soldering operation can be performed on the T-shaped pins and the power board.
[0058] In one embodiment, a soldering position hole is provided on the fixing plate, which is used to observe the state of the solder when the T-shaped pins and the power board are soldered, and to facilitate smoothly touching the position to be soldered when soldering the T-shaped pins and the power board.
