AI Technical Summary
When existing winding machines simultaneously wrap coils in different directions on the inductive skeleton, the coils are easily loosened and distracted due to the reverse rotation of the inductive skeleton, which affects the winding efficiency.
A two-way winding inductor coil winding machine is adopted. The two winding bobbins are arranged symmetrically and driven by a transmission mechanism. The winding bobbins rotate in opposite directions. Combined with the first wire sending arm and the second wire sending arm, the metal wires are synchronously wound with coils in two directions on the inductive frame.
The coils in two directions are synchronously wound on the inductive skeleton, which improves the winding efficiency and avoids the problem of loose and scattered coils.

Description
Technical Field
[0001] The utility model relates to the field of inductance production, in particular to a bidirectional winding type inductance coil winding machine. Background Art
[0002] In order to improve the efficiency of the inductor coil, a winding machine is needed to wind the metal wire onto the inductor frame to meet production requirements.
[0003] Existing winding machines rapidly wind wire onto the inductor frame by rotating the inductor frame while keeping the slender metal arm used for wire feeding stationary. To simultaneously wind two coils in different directions around the frame, the inductor frame must be rotated in opposite directions. When the winding mechanism switches its rotation, the inductor frame rotates, causing the coils on the inductor frame to loosen and become disorganized due to centrifugal force, making subsequent winding difficult.
[0004] Therefore, the purpose of the present invention is to provide a bidirectional winding inductor coil winding machine, which can simultaneously wind two coils in different directions on an inductor frame. Utility Model Content

[0007] Preferably, it also includes a second wire feeding arm, which is arranged in a one-to-one correspondence with the winding drum, and the second wire feeding arm is arranged along the radial direction of the winding drum at the end of the winding drum away from the gap. The second wire feeding arm is detachably connected to the winding drum, and the second wire feeding arm is provided with a plurality of second through holes for the metal wire to pass through at intervals, and the second through holes are parallel to the center line of the winding drum.
[0008] Preferably, the first wire feeding arm is a rod bent into an L-shape.
[0009] Preferably, the end of the second wire feeding arm away from the winding drum extends in a direction parallel to the center line of the winding drum, and a limiting hole is provided at the end of the second wire feeding arm away from the winding drum.
[0010] Preferably, the transmission mechanism includes a ring gear, a gear and a servo motor. The center line of the gear extends radially along the winding drum. The ring gears are arranged one by one at one end of the winding drum close to the gap. The two ring gears are respectively engaged with the two ends of the gear.

[0014] The workpiece fixture is a cylinder, and one end of the workpiece fixture close to the gap gradually shrinks in a direction close to the gap.
[0015] The beneficial effects of the present invention are as follows: a manipulator gripping the end of a metal wire can pass through a gap to perform operations, while a gear drives the two winding drums to rotate in two different directions. The rotation of the two winding drums causes the two first wire feed arms to rotate in two different directions.

These two coils are wound synchronously, shortening the winding time. BRIEF DESCRIPTION OF THE DRAWINGS
