Description

Technical Field

[0001] The utility model relates to the technical field of stator processing, in particular to a stator enameled wire winding mechanism. Background Art

[0002] At present, the production of motor stators adopts automatic winding by mechanical equipment. An enameled wire is wound on the stator core, and the stator core is insulated by insulating paper and end plates, and finally the three-phase wires are led out. At this time, it is also necessary to manually wind the three-phase lead wires on the end plate so that the three-phase lead wires are concentrated together. During mass production, since the operation mode and operation speed of each operator are different, the consistency of the winding of the three-phase lead wires is poor, which affects the quality of the stator. Therefore, it is necessary to propose a stator enameled wire winding mechanism. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and to provide a stator enameled wire winding mechanism.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a frame, which is characterized in that it also includes a mechanical arm installed on the frame and a clamping winding structure installed on the mechanical arm for clamping the enameled wire, and the winding structure includes a cylinder installed on the mechanical arm that can be vertically lifted and lowered, and a clamp installed on the cylinder.

[0005] Preferably, the clamp comprises a clamping cylinder mounted on the cylinder, and a first clamp and a second clamp mounted on the clamping cylinder and symmetrically.

[0006] Preferably, the first clamp and the second clamp form a gap groove when they are closed and clamped.

[0007] Preferably, the first clamp and the second clamp are provided with clamping grooves matching the enameled wire.

[0008] Preferably, the first clamp and the second clamp are also provided with wavy arc surfaces that cooperate with each other.

[0009] Preferably, the robotic arm comprises a first servo motor, a first connecting arm mounted on the first servo motor, and a second connecting arm mounted on the first connecting arm and connected to the cylinder.

[0010] Preferably, a second servo motor is mounted on the second connecting arm to drive the second connecting arm to rotate on the first connecting arm.

[0011] The beneficial effects of the utility model are as follows: through the setting of the winding structure, the control program is used to control the mechanical arm to cooperate with the winding mechanism to replace the manual winding of the three-phase lead wire, so that the winding efficiency of the stator three-phase lead wire is fast and the product quality consistency is good;

[0012] By setting the wavy arc surface, when the first clamp and the second clamp clamp the enameled wire, the wavy arc surface matched with the phase line is used to clamp the enameled wire more stably, preventing the enameled wire from detaching from the first clamp and the second clamp during winding, thereby improving stability;

[0013] By setting the gap groove, when the enameled wire is clamped at the front end of the first clamp and the second clamp, the rest of the enameled wire is located in the gap groove, preventing the enameled wire from being clamped by the first clamp and the second clamp and causing surface damage, thereby improving the use quality of the enameled wire.
