[0002] In daily life, coil skeletons such as transformers are often used. During the assembly process, two sleeves need to be installed outside the wire first, and then the wire is wound around the circumferential surface of the corresponding coil skeleton. Finally, the two corresponding sleeves are fixed to the two ends of the corresponding coil skeleton to increase its solder creep performance and pressure resistance.
[0003] In the prior art, a casing machine is generally required to thread the casing, a winding machine is generally required to wind the wire, and manual operation is generally required to tighten the casing.
[0004] For each of the above-mentioned processes, the work is independent and cannot be connected together. That is, after the wire is sleeved by the sleeve threading machine, it is necessary to unload the material, and then manually load the sleeved wire to the winding machine for winding the coil skeleton. The coil skeleton after winding needs to be unloaded again, and the sleeve is manually wrapped around its end legs. Therefore, there will inevitably be a certain period of interruption between each unloading and each loading, which makes the assembly line operation discontinuous, and then makes it impossible to effectively improve the efficiency of sleeve threading, winding and wrapping the sleeve, which makes the coil skeleton assembly production cycle long and greatly increases the labor cost and time cost.

Specifically, the aforementioned clamping jaw assembly 6 is fixedly positioned below the aforementioned wire hole and is used to grip the end of the wire passing through the wire hole from above the first movable arm 3 and bring the wire end to the winding station through the movement of the motor-screw linear module. Regarding the second movable arm 4, a wire conduit is fixed perpendicularly to the side of the second movable arm 4, and a pneumatic shear is fixed perpendicularly to the side of the second movable arm 4. The wire is first guided through the wire conduit, then clamped by the clamping jaw assembly 6 located above the first movable arm 3 and transferred to the winding station to complete the winding process. After the winding process is completed, the servo motor 5 is activated, and the pneumatic shears located above the second movable arm 4 cut the wire. The wire feeding mechanism 2 then retracts under the action of the wire, facilitating the next winding process.
[0022] The following combination Figure 2 The aforementioned motor screw linear module is described in detail.

The movement directions of the first motor screw linear module 7, the second motor screw linear module 8 and the third motor screw linear module 9 are perpendicular to each other, thereby taking into account the position adjustment requirements of the first movable arm 3 and the second movable arm 4 in space controlled by the servo motor 5.

The screw coaxially fixed with the rotating shaft of the third motor 91 is threadedly engaged with the movable block fixed on the third movable plate, thereby driving the third movable plate to reciprocate on the third slide rail.
[0026] In actual application, the wire is fed by the wire feeding mechanism 2, and then the first movable arm 3 or the second movable arm 4 fixed to the joint control position of the first motor screw linear module 7 and the third motor screw linear module 9 grabs the end of the wire to feed the wire for the winding mechanism and assist in completing the winding process. The first movable arm 3 and the second movable arm 4 are driven by the servo motor 5 and can rotate 90 degrees clockwise or counterclockwise around the rotating shaft of the servo motor 5. The first motor screw linear module 7 is set based on the height direction of the gantry 1, so the third motor screw linear module 9 can be controlled to reciprocate vertically, and the third motor screw linear module 9 is fixed on the first motor screw linear module 7 along the horizontal direction of the gantry 1 through the connecting plate 10, so the third motor screw linear module 9 can reciprocate horizontally, thereby completing the position adjustment of the first movable arm 3 and the second movable arm 4.
