[0001] The utility model relates to the technical field of welding processing devices, in particular to a positioning fixture for welding and processing a computer mainboard PCB board. Background Technique

[0002] A computer mainboard (PCB, full name: printed circuit board or motherboard) is one of the core hardware components of a computer hardware system, and all other components are connected and interacted through it.

[0003] At present, after the main body of the computer mainboard is processed, other components are usually welded on the mainboard to realize the functions of the mainboard. During welding, workers usually hold and fix the computer mainboard by hand, then align other components with the solder joints on the computer mainboard, and then weld the two together.

[0004] However, after components such as USB plugs on one side of the mainboard are welded, the surface of that side of the mainboard will be uneven, resulting in difficulty in keeping the whole mainboard horizontal when welding other components on the other side of the mainboard. As a result, it is difficult to control the balance point when docking other components and the solder joints on the mainboard during welding, making the positioning of the welding work on that side of the mainboard rather troublesome. For this reason, the utility model proposes a positioning fixture for welding and processing a computer mainboard PCB board to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning fixture for welding and processing a computer mainboard PCB board, so as to solve the problem that it is difficult to control the level of the whole mainboard after the USB plugs on the USB plug side of the mainboard are welded, resulting in difficulty in positioning other components when welding on the other side of the mainboard as mentioned in the above background technique.

[0024] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0025] Embodiment 1, a positioning fixture for soldering and processing a computer mainboard PCB. The positioning fixture for soldering and processing a computer mainboard PCB includes: a mounting base 1, a pressing plate 2, and a fastening buckle 3.

[0026] Specifically, an installation groove 5 for installing the PCB main board is provided on one side of the installation base 1. Align the USB side of the main board with the installation groove 5, and then snap-connect the main board to the installation base 1. One end of the installation base 1 is rotatably connected with a pressing plate 2. After the main board is installed, rotate the pressing plate 2 so that the pressing plate 2 covers the main board. The other end of the installation base 1 is rotatably connected with a fastening buckle 3. One end of the pressing plate 2 is fixedly connected with a fixing rod 4. One end of the fastening buckle 3 is set in an "S" shape and is snap-connected with the fixing rod 4 after the fastening buckle 3 rotates. This facilitates the snap connection between the fastening buckle 3 and the fixing rod 4 after rotation, and also facilitates the release of the snap connection of the fastening buckle 3, making it convenient for the finger to apply force. After the pressing plate 2 is in place, rotate the fastening buckle 3 to make the fastening buckle 3 and the fixing rod 4 snap-connected, thereby fixing the pressing plate 2, which also fixes the main board on the installation base 1 and keeps the side of the main board to be welded horizontal. A notch 6 is provided through the side of the pressing plate 2, and the notch 6 corresponds to the area of the PCB main board to be welded. The notch 6 facilitates the subsequent welding work.

[0027] To better protect the main board, a rubber pad is fixedly connected to the side of the pressing plate 2 in contact with the PCB main board. The rubber pad fits the surface structure of the PCB main board. The rubber pad can avoid rigid contact with the main board and make the fixation of the main board safer.

[0028] To facilitate the rotational installation of the pressing plate 2, one end of the installation base 1 of the present application is fixedly connected with a fixing block 7 in an "L" shape. One end of the fixing block 7 is rotatably connected with a second shaft sleeve 9, and the second shaft sleeve 9 is fixedly connected with the pressing plate 2. This facilitates the rotational installation of the pressing plate 2 on the installation base 1.

[0029] To better fit the pressing plate 2 to the main board after rotation, one end of the fixing block 7 of the present application is fixedly connected with a shaft rod 71, and the second shaft sleeve 9 is rotatably connected with the shaft rod 71. This can better rotatably install the second shaft sleeve 9 on the fixing block 7. One side of the second shaft sleeve 9 is fixedly connected with a connecting plate 91, and the connecting plate 91 is fixedly connected with the pressing plate 2. The connecting plate 91 can give the pressing plate 2 a certain installation space and make the pressing plate 2 rotate better.

[0030] To facilitate the rotational installation of the fastening buckle 3, one end of the fastening buckle 3 of the present application is fixedly connected with a first shaft sleeve 31. One side of the first shaft sleeve 31 is rotatably connected with a connecting rod 8, and the connecting rod 8 is fixedly connected with the installation base 1. This facilitates the rotational installation of the fastening buckle 3 on the installation base 1.

[0031] To better cooperate between the fastening buckle 3 and the fixing rod 4, the fixing rod 4 of the present application is set in a "cylindrical shape", which can make the fixing rod 4 slide better on the fastening buckle 3. One end of the connecting rod 8 is fixedly connected with a limiting rod 81, and the limiting rod 81 can prevent the fastening buckle 3 from detaching from the connecting rod 8.

[0032] During actual implementation, first align the USB soldering surface of the main board with the installation groove 5, and then snap the main board into the installation base 1, thereby preliminarily installing the main board on the installation base 1. Then rotate the pressing plate 2 so that the pressing plate 2 preliminarily covers the main board. Then rotate the fastening buckle 3 to let the fixing rod 4 snap into the groove of the fastening buckle 3, thereby fixing and pressing the pressing plate 2. The pressing plate 2 will press the main board tightly, so as to ensure that the soldering surface of the main board remains horizontal. Then when performing subsequent soldering work, the components can be well docked and positioned with the soldering points on the main board.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
