It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0021] To improve welding efficiency by fixing and assembling wires, PCB boards, and transmission coils, one embodiment of this invention proposes a combined welding fixture for wires, PCB boards, and transmission coils, such as... Figure 1 The device includes: an operating table 10; a movable stage 20 disposed on the operating table 10 for setting a PCB board; a fixed stage 30 disposed on the operating table and opposite to the movable stage 20 for setting a transmission coil; and an adjustment knob 40 and a lead screw 50 disposed on the operating table 10, wherein the adjustment knob 40 is connected to the movable stage 20 via the lead screw 50 and is used to adjust the position of the movable stage 20 on the operating table 10 to move closer to or further away from the fixed stage 30.

[0022] Specifically, in this embodiment, a fixed stage 30 is used to set up the transmission coil to facilitate pin tinning. In order to prevent solder from dripping onto the PCB board during the pin tinning process, a movable stage 20 that can move relative to the fixed stage 30 is designed to set up the PCB board. This allows the corresponding solder joints of the PCB board to be moved to the vicinity of the fixed stage 30 and combined with the pins of the transmission coil only after the pin tinning operation is completed, so as to solder the PCB board and the transmission coil.

[0023] In a further embodiment, for ease of use, the movable stage 20 is located in the middle of the operating table 10 to facilitate the installation of the PCB board; the fixed stage 30 is located at the edge of the operating table 10; the adjustment knob 40 is located on the side of the operating table 10, or the adjustment knob 40 can be located on the surface of the operating table 10 through a reversing gear structure.

[0024] In one embodiment, the operating table 10 includes: a top cover 11, with a first opening 12 in the center of its surface and parallel second openings 13 on both sides of the first opening 12; and a main cavity, with a lead screw hole on its side; wherein the top cover 11 and the main cavity are detachably configured to form a box structure. Specifically, in this embodiment, the operating table 10 is designed as a box structure with an inner cavity. The interior of the box is used to accommodate the lead screw 50 to ensure the cleanliness of the table surface, and can also be used to store solder, rosin, and other soldering supplies to improve soldering preparation efficiency. Furthermore, designing the operating table 10 as a detachable structure facilitates the combination, maintenance, and replacement of the adjustment knob 40, the lead screw 50, and the moving platform 20.

[0025] In one embodiment, a counterweight block may be provided inside the main cavity to increase the overall weight of the tooling and prevent the tooling from moving during the welding process; in addition, an anti-slip pad may be provided on the outer bottom of the main cavity to further improve stability.

[0026] In one embodiment, such as Figure 2 As shown, the movable stage 20 includes: a movable base plate 21, a traction member 22 provided in the middle of surface A of the movable base plate 21, the traction member 22 being threadedly connected to the lead screw 50, and sliders 23 on both sides of the traction member 22 that mate with the second opening 13; and a PCB board fixing member 24, the PCB board fixing member 24 being disposed on surface B of the movable base plate (e.g., ...).

Specifically, the traction member 22 and the slider 23, located on the same side of the movable base plate 21, extend into the interior of the main cavity through the first opening 12 and the second opening 13 on the upper cover 11, respectively. The slider 23 cooperates with the second opening 13 to form a sliding assembly, and the first opening 12 provides the traction member 22 with room to move. During use, the lead screw 50 can be rotated by rotating the adjustment knob 40, thereby causing the movable base plate 21 to move along the axial direction of the lead screw 50 under the drive of the traction member 22, and simultaneously moving the movable stage 20 and the PCB board fixing member 24.

[0027] In one embodiment, in order to prevent the lead screw 50 from disengaging from the traction member 22, a baffle is provided at one end of the lead screw, and the other end of the lead screw 50 passes through the traction member 22 and the side of the operating table 10 in sequence and then passes out and connects to the adjustment knob 40.

[0028] In one embodiment, the PCB board fixing member 24 includes: a limiting groove that matches the electronic component layout of the PCB board; or a fixing clip or limiting frame that matches the contour shape of the PCB board; wherein the limiting groove is at least partially disposed within the second opening to accommodate higher electronic components on the PCB board, or the fixing clip and limiting frame are at least partially disposed above the second opening to accommodate higher electronic components on the PCB board. Figure 1 As shown, it uses a limiting frame that matches the contour shape of the PCB board.

[0030] In one embodiment, the fitting portion 32 has an upwardly or downwardly curved edge to form a slotted structure, which allows the edge structure of the movable base plate 21 to be inserted into the slot to complete the docking and locking of the movable base plate 21 and the fixed base plate 31.

[0031] In one embodiment, a circular groove is provided at the center of the fixed base plate 31 to facilitate detachable connection with the conical platform 33. The conical platform 33 is kept stable by its own weight. Alternatively, magnets are provided on the back of the circular groove and the bottom of the conical platform to achieve magnetic attraction fixation between the two.
