[0002] Printed circuit boards (PCBs) are an important component of electronic devices, providing electrical connections and physical support for electronic components. A PCB consists of a substrate material, conductive patterns, an insulating layer, and a silkscreen layer. PCBs can be classified as single-sided, double-sided, or multilayer boards. Electronic components are connected to the PCB by soldering to form a complete electronic circuit.
[0003] Currently, when soldering printed circuit boards (PCBs), they are usually placed on a fixed rack for soldering. However, when soldering double-sided PCBs, after the operator finishes soldering one side, the PCB needs to be removed and the other side placed before the other side can be soldered.

The angle adjustment assembly 30 includes a drive motor 11, a first rotating shaft 12, a first bevel gear 13, a second bevel gear 14, a second rotating shaft 15, a first bearing 17, and a limiting frame 18. The upper surface of the top plate 10 is fixedly connected to the drive motor 11. Both the first electric telescopic rod 8 and the drive motor 11 are electrically connected to an external power source. The output end of the drive motor 11 is fixedly connected to the first rotating shaft 12. The side surface of the first rotating shaft 12 is fixedly connected to the first bevel gear 13. The side surface of the first bevel gear 13 meshes with the second bevel gear 14. The inner surface of the second bevel gear 14 is fixedly connected to the second rotating shaft 15. The second rotating shaft 12... The side surface of the first shaft 12 is fixedly connected to the first bearing 17, and the right surface of the second shaft 15 is fixedly connected to the limit frame 18.

The side surface of the first shaft 12 is rotatably connected to the top plate 10. By starting the drive motor 11, the first shaft 12 and the first bevel gear 13 are driven to rotate. The rotation of the first bevel gear 13 drives the second bevel gear 14, the second shaft 15, the limit frame 18 and the double-sided printed circuit board 22 to rotate, which can flip the double-sided printed circuit board 22 to the other side. The operator can weld the other side of the double-sided printed circuit board 22. The upper surface of the first electric telescopic rod 8 is fixedly connected to the second support plate 26. The inside of the second support plate 26 is provided with a second circular hole 27. The inner surface of the second circular hole 27 is fixedly connected to the second bearing 28.

[0028] Working principle: During use, firstly, adjust the distance between the two limiting frames 18 according to the size of the double-sided printed circuit board 22. By placing the double-sided printed circuit board 22 at the same height in the placement slot 19, start the double-head motor 4 to drive the threaded screw 5 to rotate. The first slider 6 and the moving plate 7 on the threaded screw 5 move, thereby adjusting the movement of the limiting frame 18 on the moving plate 7. After the two sides of the double-sided printed circuit board 22 contact the inner walls of the two placement slots 19, start the second electric telescopic rod 20 to drive the limiting plate 21 to move, so that the limiting plate 21 limits the double-sided printed circuit board 22. The operator can then weld the double-sided printed circuit board 22. After one side of the double-sided printed circuit board 22 is welded, start the drive motor 11 to drive the first rotating shaft. The first bevel gear 13 rotates with the second bevel gear 14, the second rotating shaft 15, the limiting frame 18, and the double-sided printed circuit board 22. This allows the double-sided printed circuit board 22 to be flipped to the other side, enabling the operator to weld on the other side of the double-sided printed circuit board 22. The device can adjust the angle of the limiting frame 18. After welding one side of the double-sided printed circuit board 22, the operator does not need to manually flip the double-sided printed circuit board 22, saving time for the operator to remove and place the double-sided printed circuit board 22 and improving welding efficiency. At the same time, the device is highly flexible in use and the distance between the two limiting frames 18 can be adjusted, so that the limiting frames 18 can limit printed circuit boards of different sizes.
