[0002] Existing coating machines are usually large-scale production equipment, which take up a large space, cannot coat and produce wires according to the required length, and can only coat non-sticky insulating tape. The coated wires are wrapped in multiple layers, and the insulating film of the wires will spread out by itself after being cut. Since they are wrapped in multiple layers of insulating films, the stress of the insulating film is large after the wires are coated, causing the wires to become hard. When the wires are bent during wire wrapping, they cannot be applied to the surface of the magnetic core, causing the wire package size to be too large and unable to be assembled into the shell. Therefore, a new device is needed to change the way the wires are coated. Summary of the invention

[0005] Furthermore, a controller is arranged on the base, and the controller is electrically connected to the stepping motor and the driving motor respectively, and is used to control the rotation speeds of the stepping motor and the driving motor.

[0006] Furthermore, the positioning unit includes a fixed end and a movable end that are relatively distributed. The movable end is mounted on the base and is displaced along the length direction of the transmission screw through the movable frame. The wire is positioned between the fixed end and the movable end.

[0008] Furthermore, a telescopic rod is arranged between the movable end and the fixed end, the fixed end is connected to a driving motor, and the driving motor applies a rotational driving force to the movable end.

[0015] like Figure 1As shown, a tinned soft wire coating machine includes a tape rack 2 and a positioning unit; the tape rack 2 carries a sticky insulating film, and after coating, the disconnected position of the wire 7 will not spread out by itself, the tape rack 2 is located above the base 1, and is displaced along the length direction of the base 1 through the transmission screw 3; the transmission screw 3 is connected to the stepping motor, and here, the transmission screw 3 can be a ball screw, so that the tape rack 2 can move linearly; the positioning unit is located on the base 1, and is used to position at both ends of the wire 7 of a predetermined length and straighten the wire 7; it can be connected to a drive motor to rotate the wire 7 for corresponding coating operations.

[0016] In some preferred embodiments, a controller 4 (CNC control) is provided on the base 1, and the controller 4 is electrically connected to the stepper motor and the drive motor, respectively, and is used to control the rotation speed of the stepper motor and the drive motor. By presetting the controller 4, the tape rack 2 moves while releasing the tape. During the forward movement of the sticky insulating film, the wire 7 rotates and wraps around the sticky insulating film, and the insulating film spirally wraps around the wire 7 until the tape rack 2 moves to the end of the wire 7 to complete the wrapping operation. In this process, by controlling the displacement of the tape rack 2 and the rotation of the wire 7, the sticky insulating film can be overlapped by half, one-third, etc., to insulate the wire 7, to avoid the coated insulating film being too thick and difficult to bend during use, and the spirally wound insulating film is thin and has low stress. When winding, the wire 7 is flat against the magnetic core, the size meets the design requirements, and there is sufficient reserved space.

[0017] In some preferred embodiments, the positioning unit includes a relatively distributed fixed end and a movable end, wherein the movable end is mounted on the base 1 and is displaced along the length direction of the transmission screw 3 through the movable frame 6, and the wire 7 is positioned between the fixed end and the movable end, wherein the fixed end and the movable end are respectively provided with a self-centering four-jaw chuck 5, which respectively fixes the two ends of the wire 7, and a guide rail is provided on the base 1, and the movable frame 6 moves stably along the guide rail to adjust the wire 7 to the corresponding length.

[0018] It should be noted that a telescopic rod 8 is arranged between the movable end and the fixed end, and when the movable end moves, the telescopic rod 8 is extended; specifically, the telescopic rod 8 is fixed between the two self-centering four-jaw chucks 5, and the driving motor provides a rotational driving force to the self-centering four-jaw chuck 5 at the fixed end. After starting the driving motor, the self-centering four-jaw chuck 5 at the fixed end rotates, and the self-centering four-jaw chuck 5 at the movable end connected with the self-centering four-jaw chuck 5 at the fixed end through the telescopic rod 8 rotates synchronously.

[0020] The equipment in this embodiment uses CNC to control the operation of the entire equipment, customizes and lengthens the transmission screw 3, adjusts the corresponding length of the wire 7, and the self-centering four-jaw chuck 5 tightens the wire 7 to fix it firmly and safely.
