Technical Field

[0001] The invention relates to a hook-type inductor winding machine, in particular to a hook-type two-wire inductor winding machine, and belongs to the technical field of inductor winding production. Background Art

[0002] Most of the existing hook-type inductor winding machines are designed for single-wire winding. However, for inductors that need to be wound with two wires, they are generally wound one by one, which complicates the production process. The equipment also has high requirements for the winding accuracy of the magnetic ring. If the winding accuracy is not high, it will be difficult to wind the second wire in place. Therefore, a more effective automatic winding machine that can achieve simultaneous winding of two wires is needed. Summary of the Invention

[0003] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a hook-type inductor winding machine which can perform double-wire winding at the same time and has a high degree of automation.

[0004] The present invention is achieved through the following technical solutions:

[0005] The hook-type inductor winding machine includes a frame, a feeding mechanism, a material transfer mechanism, a wire feeding mechanism, a wire arranging mechanism, a winding mechanism and a control system arranged on the frame. The characteristic is that the winding mechanism includes a rotary drive and a wire hook rod eccentrically connected to the output end of the rotary drive, and the wire hook rod has a circumferential gap that can clamp the wire.

[0006] The hook-type inductor winding machine as described above is characterized in that the wire hook rod includes a wire hook arm and a wire clamping head, the wire clamping head is arranged at the free end of the wire hook arm through a connecting shaft, a circumferential gap surrounding the connecting shaft is formed between the wire hook arm and the wire clamping head, and the wire hook rod is connected to a swing arm drive for driving it to swing.

[0024] The present invention is further described in detail below with reference to specific embodiments.

[0025] like Figure 1-8 As shown, the hook-type inductor winding machine includes a frame 1, a feeding mechanism 2, a material transfer mechanism 3, a wire feeding mechanism 4, a wire arrangement mechanism 5, a winding mechanism 6 and a control system 7 arranged on the frame 1. Each mechanism can be arranged on the frame 1 through a mounting seat. The winding mechanism 6 includes a rotary drive 61 and a wire hooking rod 62 eccentrically connected to the output end of the rotary drive 61. The wire hooking rod 62 has a circumferential gap 621 that can clamp the wire. The wire hooking rod 62 is eccentrically connected to the output end of the rotary drive 61 and is driven by the rotary drive 61 to perform circular motion around the output shaft of the rotary drive 61, so that the wire hooking rod 62 hooks the wire from the bottom of the magnetic ring, retracts, and then rises to the top of the magnetic ring, and flips the wire to facilitate the hook hooking. The winding mechanism of the present invention has a simple structure, one drive realizes two-dimensional movement, the winding mechanism is simpler, faster and more stable, and facilitates a more optimized design of the overall equipment.

[0026] Preferably, the thread hooking rod 62 includes a thread hooking arm 624 and a thread clamping head 622. The thread clamping head 622 is arranged at the free end of the thread hooking arm 624 through a connecting shaft 623. A circumferential gap 621 surrounding the connecting shaft 623 is formed between the thread hooking arm 624 and the thread clamping head 622. The thread hooking rod 62 is connected to a swing arm drive 63 that drives it to swing. More preferably, the winding mechanism 6 also includes a thread hooking rod guide assembly 64 and a thread hooking rod limiter 66 that guide the two-dimensional movement of the thread hooking rod 62. This can make the movement of the thread hooking rod 62 more stable and the work more durable. Furthermore, a connecting member 65 can be provided between the thread hooking rod 62 and the thread hooking rod guide assembly 64 to increase the rotational stability and telescopic stroke of the thread hooking rod 62. When the winding mechanism 6 is working, the rotation drive 61 drives the circumferential gap 621 end of the hook rod 62 to extend into the bottom of the magnetic ring 100 in advance and enter the position to be hooked. After the wire passes over the hook rod 62 and passes through the magnetic ring 100, the swing arm drive 63 drives the hook rod 62 to swing. The wire is close to the surface of the hook rod 62 and is located at the opening between the clamping head 622 and the hook arm 624. The hook rod 62 retracts under the drive of the rotation drive 61 so that the wire is stuck in the circumferential gap 621. The hook rod 62 continues to rise and extend to the top of the magnetic ring 100 under the drive of the rotation drive 61. In this process, the wire turns around the connecting shaft 623 in the circumferential gap 621, thereby turning the wire from the lower ring surface of the magnetic ring 100 to the upper ring surface of the magnetic ring, and the hook needle 54 can hook the wire. The hook rod 62 has a recessed position 620 for making way for the hook needle 54 to facilitate faster hooking and winding.

[0027] Preferably, the material transfer mechanism 3 includes a material transfer guide assembly 31 mounted on the frame 1. The movable terminal of the material transfer guide assembly 31 is provided with a material transfer arm 32 and a material transfer hand 33. The material transfer arm 32 is connected to a material transfer rotary drive 34 that drives it up, down, and in translation. The material transfer arm 32 is eccentrically connected to the material transfer rotary drive 34, thereby achieving two-dimensional movement of the material transfer arm 32 driven by a single power source. The material transfer guide assembly 31 improves the movement stability of the material transfer arm 32 and facilitates precise positioning.

[0028] Preferably, the wire feeding mechanism 4 includes a wire feeding drive 41, a conductor structure 42, a wire pay-off detection structure 43 and a wire break structure 44 arranged on the frame 1. The wire outlet end of the wire feeding drive 41 is provided with a wire feeding nozzle 45. The wire pay-off detection structure 43 includes a sensing member 431 that rotates under the influence of the friction of the wire during transmission and a detector 432 for detecting the sensing member 431. The sensing member 431 has at least one detection mark 4311. More preferably, the sensing member 431 is driven to rotate by a rotating member 433, and the rotating member 433 has a friction rotating surface 4331 that contacts the wire. At the same time, the wire pay-off detection structure 43 also has an adjustable wire bundle hole 434 to ensure that the wire is in contact with the rotating member 433, effectively driving the sensing member 431 to rotate. In this way, the sensing member 431 can be designed to be sheet-shaped to improve the detection sensitivity. During wire transmission, sensing element 431 rotates, maintaining a constant frequency for detection by detector 432. If a wire break or blockage occurs, sensing element 431 becomes unable to rotate. Detector 432 detects the abnormality and sends a signal back to the PLC, causing it to stop operating and facilitate timely troubleshooting. For dual-wire systems, sensing element 431, rotating element 433, and wire harness hole 434 are each grouped together to independently detect each wire. Any break in any wire triggers an alarm, preventing single-wire winding errors and quality issues with the final product.

[0029] Furthermore, the frame 1 is provided with an avoidance rotation drive 46 capable of driving the wire feeding drive 41, the wire breaking structure 44 and the wire feeding nozzle 45 to rotate around the magnetic ring 100, so that the wire feeding nozzle 45 will not affect the wire arrangement when winding the wire.

[0030] Furthermore, the wire feeding drive 41 includes a driving motor, an active wire feeding guide wheel 411 connected to the output end of the motor, and a driven wire feeding guide wheel 412 that cooperates with the active wire feeding guide wheel 411 to clamp and transmit the wire. The driven wire feeding guide wheel 412 is elastically connected to its mounting base. Specifically, the driven wire feeding guide wheel 412 is connected to the mounting base through a spring and a bolt. When the wire diameter changes, the driven guide wheel 412 can adaptively adjust the distance from the active wire feeding guide wheel 411 to ensure smooth wire feeding.

[0031] The cable arrangement mechanism 5 includes a clamping wheel assembly 51 that clamps and drives the magnetic ring to rotate and arrange the cable. The clamping wheel assembly 51 is connected to a cable arrangement drive 52 that drives its rotation and a translation drive 53 that adjusts the center position of the clamping wheel assembly 51. The translation drive 53 simultaneously controls the clamping wheel assembly 51 to clamp the magnetic ring. The frame 1 is provided with a hook 54 that extends and retracts from under the magnetic ring 100 clamped by the clamping wheel assembly 51 through the magnetic ring and a hook drive 55 that drives the hook 54 to extend and retract. Preferably, each clamping wheel in the clamping wheel assembly 51 is connected to the cable arrangement drive 52 and the translation drive 53 by a universal rod, which is more conducive to freely and accurately adjusting the center position of the magnetic ring 100 clamped by the clamping wheel assembly 51, thereby adapting to the changing center position of the magnetic ring 100 when the cable is arranged.

[0032] When the present invention is working, the control system 7 is started, the unloading mechanism 2 sends the magnetic ring to the upper material of the unloading trough, the material transfer mechanism 3 transfers the material to the wire arrangement station of the clamping wheel group 51, the translation drive 53 of the magnetic ring controls the clamping wheel group 51 to clamp the magnetic ring 100 and locate the center position, the wire feeding mechanism 4 feeds the wire, and the wire material is fed by the wire feeding nozzle 45 through the clamped magnetic ring 100 and extends to the bottom of the magnetic ring 100. The winding mechanism 6 works to flip the winding below the magnetic ring 100 to the top of the magnetic ring 100 and place it horizontally. The hook drive 55 drives the hook 54 to extend from the center of the magnetic ring 100 and hook the wire to the bottom of the magnetic ring 100, completing one winding. Under the drive of the wire arrangement drive 52, the magnetic ring 100 keeps rotating, and the winding action is cyclical to complete the wire arrangement of the magnetic ring. During the wire arrangement process, the magnetic ring can adaptively adjust its center position, and the wire feeding nozzle 45 can slightly rotate around the magnetic ring 100 to avoid the wire arrangement, ensuring that the wire arrangement of the magnetic ring is more beautiful and of better quality.
