Description

Technical Field

[0001] This utility model belongs to the field of circuit board pin soldering technology, and in particular relates to a circuit board pin soldering fixture. Background Technology

[0002] Welding fixtures are physical platforms that support electronic components. They provide electrical connection paths for components through pre-designed copper foil circuits, while also serving to fix and support the components. Electronic component circuit board processing generally requires soldering the pins onto the circuit board. The bottom of the pins is inserted through holes in the circuit board, and then soldered using a welding gun.

[0003] Since soldering circuit boards and pins requires manual assistance and the use of a soldering gun, this method is prone to misalignment during soldering and has poor limiting and fixing effects. Therefore, we propose a circuit board pin soldering fixture to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board pin soldering fixture that limits and fixes the pins during soldering to prevent misalignment, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A circuit board pin welding fixture includes a support base, a vertical plate 1 fixedly connected to the right side of the top of the support base, an electric telescopic rod fixedly connected to one side of the vertical plate 1, a movable plate fixedly connected to the telescopic end of the electric telescopic rod, a sliding rail fixedly connected to the top of the support base, the movable plate slidably disposed between the sliding rail, a vertical plate 2 fixedly connected to the top of the movable plate, a threaded rod threadedly connected to the inner surface of the vertical plate 2, a movable plate rotatably connected to one side of the threaded rod via a bearing, a sliding rod fixedly connected to the front and rear positions of the movable plate near the vertical plate 2, the sliding rod slidably disposed through the vertical plate 2, a limit component provided on the other side of the movable plate, and a limit block fixedly connected to the bottom of one side of the movable plate.

[0006] Preferably, a limiting strip and a bottom support block are fixedly connected sequentially to the left side of the top of the support base, and the bottom support block and the limiting strip are used to limit the circuit board.

[0007] Preferably, a sliding frame is fixedly connected to both the front and rear positions of the bottom of the movable plate, and the inner surface of the sliding frame is slidably connected to the outer surface of the sliding rail.

[0008] Preferably, the limiting component includes a moving rod that slides through the inner surface of the moving plate, a limiting plate is fixedly connected to one side of the moving rod, a spring is sleeved on the outer surface of the moving rod, the spring is fixedly connected to one side of the limiting plate, and the other side of the spring is fixedly connected to the moving plate.

[0009] Preferably, the limiting plate limits the diode connected to the pin, and one side of the bottom support block and the limiting strip limits the bottom and side of the circuit board, respectively.

[0010] The beneficial effects of this utility model are: 1. In this utility model, a circuit board is placed on top of a bottom support block, and the diode pins are inserted into holes in the circuit board. A limiting strip limits the side of the circuit board. An electric telescopic rod drives the moving plate to move, which is guided by a sliding rail. This moves the limiting block and limits the bottom of one side of the circuit board. A threaded rod rotates on the inner surface of the second vertical plate, and a sliding rod slides on the inner surface of the second vertical plate, which moves the moving plate. The limiting component fits and limits the diode, preventing misalignment when soldering the pins. 2. This utility model guides the movement of the moving plate by setting the outer surface of the sliding frame and the sliding rail to slide; 3. When the moving plate moves, the limiting plate moves with it. The limiting plate is in contact with the diode, and the moving rod slides through the inner surface of the moving plate and compresses the spring. This allows the limiting plate to limit the diode while preventing it from being damaged by contact. Attached Figure Description

A limit plate 14 is fixedly connected to one side of the movable rod 13. A spring 15 is sleeved on the outer surface of the movable rod 13. The spring 15 is fixed to one side of the limit plate 14. The connection is as follows: the other side of spring 15 is fixedly connected to the moving plate 10; the limiting plate 14 limits the diode connected to the pin; one side of the bottom support block 3 and the limiting strip 4 limits the bottom and side of the circuit board, respectively; when the moving plate 10 moves, it drives the limiting plate 14 to move, so that the limiting plate 14 is in contact with the diode, and the moving rod 13 slides through the inner surface of the moving plate 10 and compresses the spring 15, so that the limiting plate 14 limits the diode while avoiding collision and damage; the bottom of one side of the moving plate 6 is fixedly connected to the limiting block 12, through which...

[0015] Figure 1-4This invention illustrates a circuit board pin soldering fixture according to an embodiment of the present invention, comprising a support base 1, a vertical plate 2 fixedly connected to the right side of the top of the support base 1, an electric telescopic rod 5 fixedly connected to one side of the vertical plate 2, a movable plate 6 fixedly connected to the telescopic end of the electric telescopic rod 5, a sliding rail 7 fixedly connected to the top of the support base 1, the movable plate 6 slidingly disposed between the sliding rail 7, a vertical plate 8 fixedly connected to the top of the movable plate 6, a threaded rod 9 threadedly connected to the inner surface of the vertical plate 8, a movable plate 10 rotatably connected to one side of the threaded rod 9 via a bearing, a sliding rod 11 fixedly connected to the front and rear positions of the movable plate 10 near the vertical plate 8, the sliding rod 11 slidingly disposed through the vertical plate 8, a limit assembly provided on the other side of the movable plate 10, a limit block 12 fixedly connected to the bottom of one side of the movable plate 6, a limit strip 4 and a bottom support block 3 sequentially fixedly connected to the left side of the top of the support base 1, the bottom support block 3 and the limit strip 4 being used to limit the circuit board.

[0016] Working Principle: When using this utility model, the user places the circuit board on top of the bottom support block 3, inserts the diode's pin into the hole of the circuit board, and limits its side by the limiting strip 4. The electric telescopic rod 5 drives the moving plate 6 to move, which is guided by the sliding rail 7, thereby driving the limiting block 12 to move and limit the bottom of one side of the circuit board. The threaded rod 9 rotates on the inner surface of the vertical plate 8 and slides on the inner surface of the vertical plate 8 by the sliding rod 11, thereby driving the moving plate 10 to move. When the moving plate 10 moves, it drives the limiting plate 14 to move. The limiting plate 14 fits against the diode, and the moving rod 13 slides through the inner surface of the moving plate 10 and compresses the spring 15. This allows the limiting plate 14 to limit the diode while preventing contact and damage, thus preventing misalignment when soldering the pin and fixing the pin during soldering.
