The belt drive of the clamping wire arrangement mechanism improves the transmission power and stability of the magnetic ring, and the wire arrangement is more uniform; the winding mechanism can stably rotate to control the opening and closing of the wire clamping component, avoiding the loss of the winding during the winding process. At the same time, the winding positioning mechanism assists the winding hook to hook the wire, and the wire positioning mechanism at the specified position of the free end of the winding tightens the winding, which greatly reduces the guide and positioning requirements for wire feeding and improves the wire hooking efficiency; the automation of the tail wire breaking mechanism and the material receiving mechanism further improves the tailing efficiency after the magnetic ring is wound, and the winding machine operator only needs to collect the material basket on time.

[0025] The invention has a simple and compact structure, occupies a small space, and each mechanism is automated, thereby improving the winding production efficiency of the magnetic ring and reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figure 1-11 As shown, a hook-type magnetic ring automatic winding machine includes:

[0039] Workbench 1, used for installing various mechanisms;

[0040] A control system 2, which is provided on the workbench 1 and is used to control the operation of each mechanism;

[0041] A wire-clamping and winding mechanism 3 is provided on the workbench 1 and is used to clamp the magnetic ring and rotate it for winding;

[0042] The feeding mechanism 4 includes a vibrating material plate 41, a feeding chute 42 connected to the vibrating material plate 41, and a transfer assembly 43 for feeding the magnetic ring to the clamping station of the cable arrangement mechanism 3;

[0043] The wire feeding mechanism 5 includes a wire clamping manipulator and a wire cutting assembly 51, which is used to deliver the winding wire to a designated position, place it horizontally above the clamped magnetic ring surface, and cut the winding wire into a predetermined length;

[0044] The winding mechanism 6 includes a winding hook 61 disposed on the workbench 1 and capable of reciprocating along the axial direction of the magnetic ring within the inner diameter range of the magnetic ring clamped by the clamping and arranging mechanism 3 to pass the winding wire through the magnetic ring, and a winding module 62 capable of rotating the winding wire that has passed through the magnetic ring and then placing it horizontally above the annular surface of the magnetic ring;

[0045] The winding positioning mechanism 7 is provided on the workbench 1 and is used to deliver the winding wire placed horizontally above the magnetic ring surface to the hooking range of the winding hook 61;

[0046] The tail wire cutting mechanism 8 is arranged on the workbench 1 and is used to cut off the tail wire of the magnetic ring after winding.

[0047] In the clamping and wiring mechanism 3 of the present invention, a first clamping module 31 and a second clamping module 32 can relatively move to clamp or release a magnetic ring 10. The magnetic ring 10 is clamped by at least three rotating wheels, which are driven by a belt drive assembly. The clamping and wiring mechanism 3 also includes a guide member 33 that limits the position of a belt 34 to ensure belt tension. Belt 34 contacts the circumference of the magnetic ring 10, driving the magnetic ring 10 in rotation during transmission. Furthermore, the belt drive significantly increases the transmission area of ​​the magnetic ring 10, making it less susceptible to damage. Furthermore, the transmission power is greater and more stable, which facilitates uniform wiring of large-diameter magnetic rings and improves the quality of the magnetic ring wiring.

[0048] The material transfer assembly 43 in the feeding mechanism 4 of the present invention includes a feeding drive 431 arranged on the workbench 101 of the workbench 1 and a feeding rod 432 driven by the feeding rod to feed the material to the clamping and wiring mechanism 3. The feeding rod 432 can be telescopically inserted and removed from the magnetic ring. The free end of the feeding rod 432 is provided with an adsorption part 433 that can adsorb the magnetic ring to avoid hard damage to the magnetic ring caused by interference insertion of the magnetic ring, and at the same time prevent the magnetic ring from falling off during the transfer process. A buffer part 434 is provided between the telescopic drive end of the feeding rod 432 and its telescopic drive to prevent damage caused by excessive movement between the feeding rod 432 and its telescopic drive during the insertion process.

[0049] The wire feeding mechanism 5 of the present invention comprises a first wire gripper 52 that grips the winding wire from the wire supply base 50 and passes it through the wire cutting assembly 51, and a second wire gripper 53 that grips and delivers the winding wire passing through the wire cutting assembly 51 to a designated position. The cutter 511 of the wire cutting assembly 51 is an arc-shaped cutter that is driven by a rotary cutter driver 512 to rotate and cut the winding wire. Rotating the cutter provides greater force, faster, and more stable cutting.

[0050] The winding module 62 in the present invention includes a fixed base 621 and a rotating base 622 that can rotate relative to the fixed base 621. The rotating base 622 is connected to its rotation drive 625. The rotating base 622 is provided with a wire clamping assembly 623 that can rotate around the magnetic ring following its rotation. The fixed base 621 is provided with an opening and closing drive 624 that can enable the wire clamping assembly 623 to clamp the winding when the wire clamping assembly 623 is located at a set position below the magnetic ring, and can enable the wire clamping assembly 623 to loosen the winding after the wire clamping assembly 623 rotates around the magnetic ring with the clamped winding at a set angle.

[0051] Preferably, the wire clamp assembly 623 includes a wire clamp frame 6231 mounted on the rotating base 622. The wire clamp frame 6231 is provided with a fixed chuck 6232 and a movable chuck 6233 that can move away from or toward the fixed chuck 6232. The driving end 6235 of the movable chuck 6233 is provided with a mating portion 6234 that can cooperate with the opening and closing drive 624. A return spring (not shown) is also provided between the movable chuck 6233 and the wire clamp frame 6231 to push the movable chuck 6233 back to its original position. The driving end 6235 is a sleeve within which the return spring is disposed. The opening and closing drive 624 includes a circumferentially continuous convex and concave surface mounted on the fixed base 621. The mating portion 6234 is a roller that can roll on the convex and concave surfaces when the rotating base 622 rotates. When the roller rotates to the convex surface, the fixed clamping head 6232 and the movable clamping head 6233 are clamped, and when the roller rotates to the concave surface, the fixed clamping head 6232 and the movable clamping head 6233 are loosened.

[0052] Furthermore, the wire clamping frame 6231 is frame-shaped when the fixed clamping head 6232 and the movable clamping head 6233 are combined.

[0053] Preferably, a transition surface 6243 is provided between the convex surface 6241 and the concave surface 6242 of the opening and closing drive 624. During the rotation process, when the wire clamping assembly 623 rotates to the transition surface 6243, the winding is in a semi-clamped state, which facilitates the winding hook 61 to hook the wire downward.

[0054] Furthermore, the wire clamping frame 6231 is frame-shaped. When the fixed chuck 6232 and the movable chuck 6233 are closed, they form a closed frame to define the winding path. More preferably, a limiting rod 6236 is provided between the fixed chuck 6232, the movable chuck 6233, and the wire clamping frame 6231 to further define the winding path and ensure that the winding hook 61 once again hooks the thread. The gap between the two limiting rods 6236 is connected to the opening between the fixed chuck 6232 and the movable chuck 6233. Preferably, the fixed chuck 6232 and the movable chuck 6233 form a figure-eight shape to guide the winding.

[0055] In a preferred embodiment of the present invention, the winding positioning mechanism 7 includes an auxiliary hook 71 that can reciprocate to pull the winding hook above the clamped magnetic ring into the winding hook 61, and an auxiliary hook driver 72 that drives the auxiliary hook 71 to reciprocate. The auxiliary hook 71 can greatly reduce the winding wire feeding positioning accuracy. Even if the winding wire is fed off-center, the auxiliary hook 71 can still feed the winding wire to the winding hook 61 to ensure that the wire is hooked.

[0056] The workbench 1 is also provided with a line setting mechanism 11 which can receive the winding wire transmitted by the wire feeding mechanism 5. The line setting mechanism 11 is a retractable rotating wire clamping finger 111. The rotating wire clamping finger 111 can be opened and closed under the action of the rotation drive to clamp or loosen the wire, which is more conducive to the hooking of the winding hook 61. Figure 3-4 and Figure 9As shown, the rotating thread clamping finger 111 is two fingers connected in a sleeve, and the rotation of one of the fingers can realize the opening and closing of the two thread clamping fingers. In the present invention, two thread fixing mechanisms 11 are preferably used to facilitate the fixing of thread clamps in different directions.

[0057] The workbench 1 is also provided with a receiving mechanism 9 that can deliver the wound magnetic ring from the clamping station of the clamping mechanism 3 to the receiving position. The receiving mechanism 9 includes a retractable receiving rod 91 for inserting or removing the wound magnetic ring and a blocking rod 92 that cooperates with the receiving rod 91 to insert and clamp the wound magnetic ring. The two cooperate to prevent the receiving rod 91 from being too tight when inserting the material and damaging the wound magnetic ring, thereby improving the quality of the magnetic ring.

[0058] Preferably, the material receiving mechanism 9 and the feeding rod 432 are arranged on the same base and share a moving drive, saving structure and space.

[0059] The material receiving mechanism 9 further comprises a material discharge port 93 provided on the workbench 1. Instead of providing a material receiving basket on or in the workbench, a larger material receiving basket can be provided directly outside the workbench 1.

[0060] Preferably, a limiting ring seat 12 is further provided between the workbench 1 and the clamped magnetic ring, and the winding hook 61 passes through the limiting ring seat 12 when hooking the thread. The limiting ring seat 12 has an opening 121 and a locking pin 122 that can close the opening. A guide tube 123 is provided outside the limiting ring seat 12, and the guide tube 123 has an inclined groove. The locking pin 122 has an unlocking push rod extending from the inclined groove of the guide tube 123, and the unlocking push rod is connected to a spring 124 for resetting the locking pin 122.

[0061] The tail thread cutting mechanism 8 of the present invention includes a fixed blade holder 81 and a movable blade holder 82 that moves relative to the fixed blade holder 81. Wedge-shaped blades 820 and / or 810 are provided on the fixed blade holder 81 and / or the movable blade holder 82. Flat surfaces that mate with the wedge-shaped blades are provided on the movable blade holder 82 and / or the fixed blade holder 81. The winding hook 61 passes through the gap between the fixed blade holder 81 and the movable blade holder 82 when hooking the thread.

[0062] The working principle of the present invention is as follows: the feeding mechanism 4 unloads the material, the material transfer component 43 takes the material and sends it to the clamping station of the clamping and arranging mechanism 3 to be clamped by the first clamping module 31 and the second clamping module 32, the wire reel is unwound to the wire supply seat 50, the first wire clamping robot 52 clamps the winding wire and passes it through the tangent component 51, and then the second wire clamping robot 53 clamps the winding wire from the outlet end of the tangent component 51 and moves it to the wire fixing mechanism 11, the rotating wire clamping finger 111 opens to let the winding wire pass through and then closes to clamp the winding wire. During the wire feeding process, the auxiliary hook 71 and the winding hook needle 61 have both moved to above the magnetic ring 10, the auxiliary hook 71 is placed horizontally above the magnetic ring surface, the winding hook needle 61 passes through the magnetic ring 10 and stands vertically above the magnetic ring. After feeding the wire, the auxiliary hook 71 moves and retracts to pull the winding hook toward the winding hook needle 61, and the winding hook needle 61 moves downward to pull the winding hook through the ring hole of the magnetic ring 10 and passes through the limit When the wire clamping assembly 623 rotates to the concave surface, the winding passes through the magnetic ring again, and the movable clamp 6233 resets and leaves the fixed clamp 6232, completely releasing the winding, and the wire clamping assembly 623 continues to rotate, repeating the above winding action, and the magnetic ring winding is completed.
