[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] like Figure 1 and Figure 2 As shown, this application provides a broken line mechanism for automated production of motor stators, including a stator support 1, a line-stopping component 3, and a broken line component 4.

[0035] The stator support 1 is provided with a mounting groove extending in the vertical direction. The mounting groove is used to place the stator 2 and keep the axial direction of the stator 2 vertical. At the same time, it ensures that the terminals of the stator 2 protrude from the upper surface of the stator support 1.

[0036] The abutment assembly 3 is disposed on one side of the stator support 1. The assembly consists of abutment seat 31 and abutment drive member 32. The abutment seat 31 and the abutment drive member 32 are driven to connect. The abutment drive member 32 can drive the abutment seat 31 to move horizontally toward the stator 2, so that the abutment seat 31 can accurately press the wires on the stator 2 into the wire groove of the stator 2.

[0037] The folding line assembly 4 is installed on the abutment assembly 3 and can move synchronously with the movement of the abutment seat 31. The assembly includes a folding line seat 41 and a folding line drive 42. The folding line seat 41 and the folding line drive 42 are drivenly connected. The folding line drive 42 can drive the folding line seat 41 to move linearly in a direction perpendicular to the movement of the abutment seat 31, so that the folding line seat 41 can accurately bend the wiring on the stator 2 to the preset process position.

[0038] The bending mechanism of this application achieves integrated operation of automatic positioning and bending of stator wiring through the coordinated cooperation of the bending component 3 and the bending component 4, effectively solving the problems of low efficiency and insufficient accuracy of traditional manual bending process.

[0039] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, the line-stopping assembly 3 includes a first mounting base 33 and a slide 34. The first mounting base 33 is fixedly mounted on an external mounting foundation or frame, providing a stable support reference for the entire line-stopping assembly 3. The fixed end of the line-stopping drive member 32 is fixed to the first mounting base 33 by bolt connection or flange mounting, ensuring a rigid connection of the drive mechanism. The movable end of the line-stopping drive member 32 transmits power to the slide 34 through a coupling or direct connection, and the slide 34 reciprocates linearly along a linear guide rail or guide shaft. The line-stopping seat 31 is fixed to the slide 34 by an adjustable mounting structure, and its position can be finely adjusted according to different specifications of stator 2. This line-stopping assembly 3 can not only keep the movement trajectory of the line-stopping seat 31 stable, but also ensure precise control of the force and displacement when pressing against the stator 2 for wiring, while facilitating maintenance and component replacement.

[0040] like Figure 1 and Figure 2As shown, in a specific embodiment of this application, the working end face of the wire abutment 31 is provided with a V-groove 311, the opening of which faces the stator 2. When the wire abutment drive 32 drives the wire abutment 31 to move towards the stator 2, the wire extending from the stator 2 gradually enters the V-groove 311 under the pushing action of the wire abutment 31. The inclined surface design on both sides of the V-groove 311 can guide the wire of the stator 2, ensuring accurate centering of the wire. As the wire abutment 31 continues to move, the bottom of the V-groove 311 stably presses the wire into the wire groove of the stator 2. This V-groove 311 structure not only improves the accuracy of wire positioning but also effectively prevents the wire from shifting or deforming during the pressing process, ensuring the smooth progress of subsequent wire bending processes. The size of the V-groove 311 can be adjusted according to the wire diameter of different stator 2 specifications to meet the production needs of various stator models.

[0041] like Figure 1 and Figure 2 As shown, in one specific embodiment of this application, the fixed end of the zigzag drive component 42 is fixed to the slide block 34 by bolt connection or flange mounting to ensure the stability and rigidity of the drive mechanism. The movable end of the zigzag drive component 42 transmits power to the zigzag seat 41 through a coupling or direct connection, enabling the zigzag seat 41 to move linearly along a predetermined trajectory. The zigzag drive component 42 drives the zigzag seat 41 to maintain a perpendicular relationship with the moving direction of the abutment seat 31, thereby ensuring that the zigzag seat 41 can accurately act on the positioned stator 2 wiring. The stroke and position of the zigzag seat 41 can also be adaptively adjusted according to the wiring requirements of different stator 2 specifications.

[0042] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the working end of the bending seat 41 is provided with a notch protrusion 411. In its initial position, the notch protrusion 411 is directly above the V-groove 311 and maintains a certain distance. When the bending drive 42 is working, it can control the notch protrusion 411 to move downwards vertically, gradually approaching the stator 2 wiring in the V-groove 311. When the notch protrusion 411 cooperates with the V-groove 311, it can apply a vertically downward bending force to the stator 2 wiring, causing the wiring to be bent at a preset angle and position. After completing the bending process, the bending drive 42 drives the notch protrusion 411 back to its initial position, preparing for the next work cycle. The end shape of the notch protrusion 411 is optimized to form a good fit with the V-groove 311, ensuring that the wiring surface is not damaged during the bending process, while also ensuring the consistency of the bending angle.

[0043] like Figure 1 and Figure 2As shown in a specific embodiment of this application, to improve the processing efficiency of stator 2 wiring, the wire-stopping assembly 3 and the bending assembly 4 adopt a multi-station synchronous operation design. Specifically, multiple sets of wire-stopping assemblies 3 and bending assemblies 4 are evenly distributed along the circumference of the stator support 1, with each set corresponding to a wiring processing position on the stator 2. The wire-stopping seat 31 of each wire-stopping assembly 3 works independently, driven by its respective wire-stopping drive 32, to achieve accurate positioning of the wiring at the corresponding position; the bending seat 41 of each bending assembly 4 operates synchronously, controlled by the corresponding bending drive 42, to complete the synchronous bending operation of the wiring. This multi-station arrangement allows all wiring of the stator 2 to complete the positioning and bending processes within the same processing cycle, significantly improving production efficiency. The motion parameters of each component can be independently adjusted according to the specific specifications of the stator 2 to ensure consistent processing accuracy of wiring at different positions.

[0044] like Figure 1 and Figure 3 As shown in a specific embodiment of this application, to further improve the assembly quality of the stator 2 and the circuit board, the bending mechanism is further provided with a circuit board pressing assembly 5. The circuit board pressing assembly 5 is located directly above the stator support 1 and includes a pressing head 51 and a pressing head drive 52. The pressing head 51 is connected to the output end of the pressing head drive 52, which is fixedly mounted on the base frame. Before bending the wiring of the stator 2, the pressing head drive 52 drives the pressing head 51 to move downwards in the vertical direction, so that the working surface of the pressing head 51 maintains parallel contact with the circuit board at the wiring end of the stator 2. The pressing head 51 applies uniform pressure to stably press the circuit board against the wiring end of the stator 2, providing accurate positioning for subsequent bending processes. The downward stroke and pressure of the pressing head 51 can be controlled by the pressing head drive 52 to adapt to the assembly requirements of circuit boards of different thicknesses.

[0045] like Figure 1 and Figure 3 As shown, in a specific embodiment of this application, the pressure head drive component 52 adopts a linear drive structure, specifically including a fixed base 521, a driver 522, and a movable base 523. The fixed base 521 is fixedly installed at the top of the base frame by bolts, providing a stable installation reference for the entire drive system. The fixed end of the driver 522 is rigidly connected to the fixed base 521, and its movable end is connected to the movable base 523. The movable base 523 reciprocates in the vertical direction. The pressure head 51 is fixed to the lower end face of the movable base 523, and its position can be finely adjusted according to different specifications of circuit boards. When the driver 522 is working, it drives the pressure head 51 to move in the vertical direction by controlling the lifting and lowering movement of the movable base 523, thereby realizing the smooth pressing and separation of the pressure head 51 on the stator 2 terminal circuit board. The driver 522 can specifically be a hydraulic / pneumatic cylinder, an electric push rod, etc.

[0046] like Figure 1and Figure 4 As shown, in a specific embodiment of this application, the bending mechanism is provided with a second mounting base 6 and a rotary drive 7. The second mounting base 6 is mounted on the equipment frame, providing a stable mounting foundation for the rotary drive 7. The fixed end of the rotary drive 7 is connected to the second mounting base 6, and its movable end is connected to the stator support 1 via a coupling. Under the drive of the rotary drive 7, the stator support 1 can rotate around its axis, and the rotation angle is controlled by the control system according to the number of wiring positions of the stator 2. When a set of wiring completes the bending process, the rotary drive 7 drives the stator support 1 to rotate by a predetermined angle, so that the next set of wiring accurately enters the bending working position. This rotary positioning system works in conjunction with multiple sets of wire-stopping components 3 and bending components 4 to realize the sequential processing of wiring at each position of the stator 2, which not only ensures processing accuracy but also improves production efficiency. The rotary drive 7 is driven by a servo motor or a stepper motor to ensure that the rotational positioning accuracy of the stator 2 meets the process requirements.

[0047] like Figure 1 and Figure 4 As shown, in a specific embodiment of this application, the broken line mechanism is further provided with a sliding component 8 for realizing the linear displacement function of the second mounting base 6. The second mounting base 6 is rigidly connected to the movable part of the sliding component 8, while the fixed part of the sliding component 8 is fixedly connected to the equipment frame. When the sliding component 8 is working, it can drive the second mounting base 6 and its on-board rotary drive component 7, stator support seat 1, and other components to move linearly in a preset direction, thereby moving between various workstations. The sliding component 8 can be implemented in various forms, including but not limited to a lead screw and nut mechanism, a slide rail and slide block mechanism, and a linear motor drive mechanism. When a lead screw and nut mechanism is used, a servo motor drives the lead screw to rotate, driving the nut and the second mounting base 6 to achieve precise displacement; when a slide rail and slide block mechanism is used, a cylinder or hydraulic cylinder drives the slide block to slide along the slide rail, realizing the position adjustment of the second mounting base 6. The sliding component 8 enables the stator 2 to switch positions between different workstations, meeting the needs of multi-process processing and enhancing the process adaptability and operational flexibility of the broken line mechanism.
