Description

Technical Field

[0001] This invention relates to the field of flat wire motor assembly equipment technology, and in particular to a mechanism and method for restricting manual insertion of the Ipin wire. Background Technology

[0002] Flat wire motors typically consist of a stator, rotor, and reducer, with the stator being one of the core components. The stator is the stationary part of the motor, usually composed of coils wound with copper wire, and is fixed in place within the motor housing. Its main function is to generate a magnetic field, driving the rotor to rotate and thus completing the motor's operation.

[0003] The primary function of the stator in a flat-wire motor is to generate a magnetic field, which can be a constant direct current (DC) magnetic field or a changing alternating current (AC) magnetic field. When the current through the stator coils changes, a change in magnetic flux is generated in the conductor. This change in magnetic flux affects the shape of the magnetic field, which in turn determines the direction and speed of the rotor's rotation. The magnetic field generated in the stator interacts with the magnetic field present in the rotor, causing the rotor to rotate under the influence of torque.

[0004] During the production and processing of flat wire motor stators, bent copper wires need to be manually inserted into the stator core. However, manually inserting the wires directly into the stator results in uneven ends of the wire crown, damage to the straightness of the copper wires, significant deviation in the position of the Upin clip, significant deviation in the Ipin clip angle, and poor stability, which significantly affects subsequent stator assembly work. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a mechanism and method for simulating the torsional force and trajectory of flat copper wire. The technical solution of this invention is implemented as follows: The first aspect of this invention discloses a mechanism for restricting manual insertion of I-pin cables, the insertion mechanism comprising a card-issuing insertion reel, an I-type card-issuing limiting block, a lower insertion reel, a lifting and positioning mechanism, a tooling base, and a slot number marking reel; The slot number label is located inside the card insert plate, and a plurality of first insert slots are provided between the slot number label and the card insert plate. The lower connector is provided with a second connector slot corresponding to the position of the first connector slot. The card insert reel and the lower insert reel are connected by a guide post; The lower cable tray and the tooling base are fixed by support columns; The lifting and positioning mechanism is fixedly connected to the lower surface of the slot number labeling plate; The card-issuing insert reel is provided with several I-type card-issuing limit blocks along its circumference. The type I card limiting block is used to fix the Ipin line.

[0006] Furthermore, the type I hairpin limiting block includes a limiting block and a spring; The limiting block is disposed in the first insertion slot, and the spring is disposed on the surface of the limiting block away from the Ipin wire.

[0007] Furthermore, the type I hairpin limiting block also includes a pull button; The pull button is located on the outer circumference of the hair clip insert and is connected to the spring.

[0008] Furthermore, the tooling base is provided with a through hole for the lifting and positioning mechanism to pass through; The through hole is provided with a limit adjustment device in the circumferential direction; The limit adjustment device is used to limit the position of the lifting and positioning mechanism.

[0009] The second aspect of this invention discloses a method for restricting manual insertion of an I-pin cable. This method is implemented using the insertion mechanism disclosed in the first aspect of this invention, and includes the following steps: First, manually insert the Ipin wire into the first and second slots of the card insert plate in the order of the slot number markings; After the wire is inserted, the outermost I-pin wire is held in place by the type I hairpin limiting block; Transport to the next workstation via an external transplanting mechanism or by manually gripping the tooling base; The lifting and positioning mechanism lifts the card-issuing connector and the lower connector to the assembly station; Finally, the lifting mechanism causes the card-issuing and lowering reels to fall, leaving the Ipin wire winding in place for subsequent assembly.

[0010] The advantages of this invention are as follows: 1. Make a hair clip insertion plate that mimics the shape of the stator core with different slot numbers, and mark the slot number for easy positioning of U-shaped and I-shaped hair clips; 2. Add a wire-blocking positioning block around the circumference of the wire reel to the position of the type I hairpin, thereby restricting the position of the type I hairpin and tightening the winding; 3. The cable insertion fixture can accommodate a pallet, allowing the cable to flow into the production line for convenient production; 4. The connector reel has a lifting and positioning mechanism underneath, which can lift and lower the winding to remove the connector fixture; 5. The lower end of the winding has a toothed lower insert spool to ensure the straightness of the copper wire in the winding. Attached Figure Description
