Embodiment 1

[0051] Such as Figure 1-10 As shown, a printed board 4 socket 5 positioning welding device, including a fixed plate 1 and a plug 2, the fixed plate 1 includes a plug 2 mounting plate 11 and a guide positioning plate, one end of the guide positioning plate and the plug 2. The installation board 11 is connected, the plug 2 is installed on the installation board 11, and the guide positioning plate is limitedly matched with the printed board 4 so that the socket 5 on the printed board 4 is correspondingly engaged with the plug 2 .

[0052]The beneficial effects of this embodiment are: the positioning of the printed board 4 is realized through the guide positioning plate, the position of the plug 2 is fixed through the plug 2 mounting plate 11, the position of the plug 2 can be adjusted accurately in advance, and the printed board is realized through the plug 2. The precise positioning of the socket 5 on the 4 ensures the good consistency of the positioning size of the socket 5 a...

Embodiment 2

[0054] Such as Figure 1-10 As shown, a printed board 4 socket 5 positioning welding device, including a fixed plate 1 and a plug 2, the fixed plate 1 includes a plug 2 mounting plate 11 and a guide positioning plate, one end of the guide positioning plate and the plug 2. The installation board 11 is connected, the plug 2 is installed on the installation board 11, and the guide positioning plate is limitedly matched with the printed board 4 so that the socket 5 on the printed board 4 is correspondingly engaged with the plug 2 .

[0055] Specifically, No. 20 steel is used for the fixing plate 1 to ensure its good machinability and rigidity. After the fixed plate 1 is processed, the surface is galvanized to ensure that it has better anti-rust and anti-corrosion properties; the positioning of the printed board 4 is realized through the guide positioning plate, and the position of the plug 2 is fixed through the plug 2 mounting plate 11, which can be pre-installed. Accurately ad...

Embodiment 3

[0073] A method for welding socket 5 on printed board 4, using the above-mentioned positioning welding device for socket 5 on printed board 4, the steps include:

[0074] S1: the pin of socket 5 is inserted in the welding hole 41 of printed board 4, described socket 5 is loosely connected with described printed board 4 by fixing bolt 6;

[0075] S2: Cooperate the printed board 4 with the guide positioning plate so that the socket 5 on the printed board 4 is correspondingly engaged with the plug 2;

[0076] S3: Tighten the fixing bolt 6, so that the socket 5 is tightly connected with the printed board 4;

[0077] S4: the printed board 4 is fixedly connected with the guide positioning plate;

[0078] S5: Soldering the socket 5 pins on the printed board 4 .

[0079] The beneficial effect of adopting the above solution is: this solution has all the beneficial effects of the above-mentioned positioning welding device for the printed board 4 socket 5, and will not be repeated here...

Abstract

The invention relates to a printed circuit board socket positioning welding device and method. The device includes a fixing board and a plug, wherein the fixing board includes a plug mounting board and a guide positioning board, one end of the guide positioning board is connected with the plug mounting board, the plug mounting board is equipped with a plug, and the guide positioning board is in limit matching with a printed circuit board to make a socket on the printed circuit board correspondingly clamped with a plug. Positioning of the printed circuit board is achieved through the guide positioning board, position fixing of the plug is achieved through the plug mounting board, the position of the plug can be accurately pre-adjusted, accurate positioning of the socket on the printed circuit board is achieved through the plug, good consistency of the positioning size of the socket is guaranteed, good interchangeability of the printed circuit board is guaranteed, after positioning of the socket on the printed circuit board, the printed circuit board is fixed on the device, the printed circuit board is integrated with the device into one body, enforcement of welding operation of theprinted circuit board and the socket is facilitated, and welding efficiency is improved.

Description

technical field [0001] The invention relates to the field of printed board welding equipment, in particular to a printed board socket positioning welding device and method. Background technique [0002] There are two sockets on the printed board that are assembled by soldering. The front view of the printed board and socket assembly structure is as follows: figure 1 As shown, the reverse view of the printed board and socket assembly structure is as follows figure 2 shown. During subsequent use, the two sockets on the printed board need to be docked with the plugs on the composite motherboard. The two sockets on the printed board need to have high positioning accuracy to ensure the accuracy of the center distance between the two sockets and the parallelism between the two sockets and the contact plane of the plug. Otherwise, it is prone to the problem of bending and damaging the pins when the printed board socket is docked with the plug on the motherboard; when it is use...
