The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0026] like Figure 1-3 As shown, after the mutual inductor to be welded is transferred to the work station to be clamped and welded by automated equipment, the utility model can be used for clamping, transfer and welding.

[0027] In this embodiment, a transformer conductive foot welding mechanism is provided, including a clamping and transporting assembly, a tin storage fixed base plate 15, the tin storage fixed base plate 15 is arranged on one side of the clamping and transporting assembly, and the tin storage fixed base plate 15 is used to fix a container for placing flux and liquid tin. A tin melting furnace 14 is fixedly arranged on the tin storage fixed base plate 15, and the tin melting furnace 14 is equipped with liquid tin. The tin melting furnace 14 can maintain a certain temperature to keep the tin in a liquid state; the clamping and transporting assembly is provided with an automatic clamp 8 for clamping the transformer, and the automatic clamp 8 is set above the tin melting furnace 14 and the container (flux basin 11) for placing the flux. When welding is required, the automatic clamp is fixedly arranged at one end of the flip connector, and the flip connector is used to control the flipping of the automatic clamp, so that the protruding terminal on the transformer clamped by the automatic clamp can successively contact the flux and the molten tin liquid to complete the spot welding. In this embodiment, in order to prevent the transformer housing from being stained with tin, a tin blocking plate (not shown in the figure) is fixedly arranged on the top of the automatic clamp. In addition, a through hole is provided on the tin blocking plate installed on the top of the automatic clamp to allow the terminal to pass through and facilitate welding.

[0028] The automatic clamping claw 8 will clamp the mutual inductor from the indexing plate and pass through the flux basin 11 and the tin melting furnace 14 in sequence to complete the welding.

[0029] In this embodiment, the tin storage fixed base plate 15 is also fixedly provided with an automatic feeding table 16, which is used for feeding flux. A storage tank 13 is installed on the automatic feeding table 16, and the storage tank 13 stores flux. A flux basin 11 is fixedly provided on the automatic feeding table 16, and one side of the flux basin 11 is connected with a flow groove 12, and one end of the flow groove 12 is connected to the storage tank 13. The storage tank 13 flows the flux out to the flow groove 12, and the flow groove 12 flows to the flux basin 11 again. The storage tank 13 is arranged upside down, and its opening is facing downward. The storage tank 13 is connected to the flux basin 11 through the flow groove 12. The flow groove 12 can heat the flux so that the flux can circulate in a liquid state. At the same time, because the storage tank 13 is connected to the flow groove 12, the storage tank 13 can be heated, so that the flux inside the storage tank 13 is continuously replenished to the flow groove 12.

[0030] The automatic clamping jaw 8 of the flow slot 12 is set above the flux basin 11. The flux basin 11 is set upstream of the path of the automatic clamping jaw 8 corresponding to the movement to the soldering furnace below. The flux basin 11 is set on one side of the tin melting furnace 14. Therefore, when the conductors and terminals of the transformer need to be soldered, they need to dip some flux first and then pass through and dip in the flux basin 11.

[0031] The clamping and moving assembly includes a flip connector, a lifting seat 4 and a moving platform 5. The lifting seat 4 is slidably connected to the moving platform 5. The moving platform 5 is used to control the horizontal movement of the lifting seat 4. The lifting seat 4 is connected to the flip connector, and the lifting seat 4 controls the movement of the flip connector in the vertical direction. The specific flip connector can flip the mutual inductor so that it can be carried at a certain angle, which is convenient for the wires and terminals on the mutual inductor to fully contact the flux and tin liquid. The lifting seat 4 can also make the clamping cylinder 8 rise and fall to a certain extent, and the moving platform 5 can move the clamping cylinder 8 to a specific position. Photoelectric sensors 10 are also installed on both sides of the moving platform 5. The side walls of the lifting seat 4 are also fixedly provided with induction sheets 17 corresponding to the photoelectric sensors 10. The photoelectric sensors 10 can sense the induction sheets 17 and suspend the movement of the lifting seat 4. The photoelectric sensors 10 are electrically connected to the linear screw slide rails 2 mentioned below, so they can prevent the lifting seat 4 from excessive movement, collision, and automatic limit of the lifting seat 4.

[0032] In this embodiment, the flip connector includes a first motor 1, an L-shaped flip arm 7 is fixedly provided at the output end of the first motor 1, the operation of the first motor 1 can control the rotation of the L-shaped flip arm 7, an automatic clamp 8 is fixedly provided at one end of the L-shaped flip arm 7, and a pair of profiling clips 9 are fixedly provided at the output end of the automatic clamp 8 of the first motor 1, and the closing of the profiling clips 9 can just clamp the housing of the transformer. The role of the L-shaped structure here is that compared with the linear type, the clamp installed on the L-shaped structure protrudes outward, which can shorten the stroke of the linear guide rail and avoid interference and collision between the linear guide rail and the conveying mechanism of the transformer.

[0033] In this embodiment, the lifting seat 4 is provided with a lifting drive member 6, which is specifically a lifting screw guide rail. The end of the lifting drive member 6 is fixedly connected to the flip connection member, and the flip connection member is movably connected to the lifting seat 4 through the lifting drive member 6. In order to reliably fix the connection, a connecting plate can be optionally fixed at the bottom of the first motor 1, and the end of the piston rod of the lifting drive member 6 is mainly fixed to this connecting plate to control the up and down movement of the flip connection member, so as to realize the up and down movement of the clamping cylinder 8 relative to the tin melting furnace 14 and the flux basin 11).

[0034] To further illustrate, the transport platform 5 is equipped with a linear screw guide rail 2 and a linear guide rail 3, the lifting seat 4 is slidably connected to the transport platform 5 through the linear guide rail 3, the output end of the linear screw guide rail 2 is fixedly connected to one side of the lifting seat 4, and the linear screw guide rail 2 is used to control the lifting seat 4 to slide horizontally. The linear guide rail 3 includes a guide rail and a slider, the guide rail is fixedly arranged on the transport platform 5, and the slider is slidably arranged on the guide rail, and the slider is fixedly connected to the top of the lifting seat 4.

[0035] In summary, the specific action process of the utility model is as follows: the automatic clamp 8 turns the transformer with the terminal downward by turning over the connecting piece,

[0036] The automatic gripper 8 is assisted by the lifting seat 4 and the transfer platform 5 to move forward to the flux basin 11 filled with flux and the tin melting furnace 14, and is sequentially dipped in flux and then in molten tin liquid to complete soldering. The lifting seat 4 controls the automatic gripper 8 to further descend so that the terminal is dipped in flux, and then lifts the entire flip connector. The automatic gripper 8 is controlled by the transfer platform 5 to move forward to the tin melting furnace, where it descends and is dipped in solder to complete soldering.

[0037] After welding is completed, the automatic clamp 8 resets the flipped connector, the mutual inductor returns to the top, and the automatic clamp 8 moves to the front end along the transfer platform 5 and releases, and the mutual inductor is discharged. Finally, the automatic clamp 8 resets to the other end of the transfer platform 5, and clamps another mutual inductor for welding.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
