Description

Technical Field

[0001] The utility model relates to the technical field of transformer coil welding, in particular to a multi-station coil welding device. Background Art

[0002] Transformer winding machines play a crucial role in the transformer production process. They are primarily used to wind transformer coils. The machine loads the wire into the machine's lead path, selects the appropriate lead method, and uses a motor to drive the winding shaft to rotate. The machine also controls the wire tension and winding speed to ensure the wire is evenly wound around the coil bobbin. During operation, a welding machine is required to weld the transformer wire ends. During welding, the welding current passes through the wires, generating heat that melts the metal at the contact point, forming a pool of liquid metal. When the welding current is turned off, the liquid metal pool begins to solidify, forming a weld point that firmly connects the two wires.

[0003] For example, the Chinese authorized patent with announcement number CN115121897A, "A Transformer Coil Lead Welding Device", includes a frame, wherein a transformer coil is placed on the middle support plate of the frame, a robotic arm is installed on the upper support plate of the frame, a welding structure is installed at the arm end of the robotic arm, and a tin breaking structure is installed on the frame. The motor drives the tin wire turntable and the second and third gears for tin breaking to rotate simultaneously through a synchronous belt, thereby avoiding deformation or even breakage of the tin wire due to excessive pressure on the tin wire.

[0004] Although the above-mentioned existing technology can realize the welding of transformer wire ends, with the continuous expansion of production scale, there are more workstations for wire end welding. However, the welding machine is large in size and is not convenient to use with multiple workstations, which affects the welding efficiency of the transformer wire ends. Therefore, it does not meet the existing needs. In this regard, we propose a multi-station coil welding device. Utility Model Content
