[0004] The cross-winding magnetic winding machine uses a winding method that uses two clamping units of a clamping device to wind a wire on a magnetic ring, wherein the first clamping unit is used to wind one half of the magnetic ring, and the second clamping unit is used to wind the other half of the magnetic ring. However, in order to meet the different needs of the market, in the prior art, some cross-winding winding machines use each clamping unit on one side of the magnetic ring to respectively cooperate with a wire hooking device and a winding device to complete the winding of a wire. That is, after the winding is completed, a wire is wound on the first side and the second side of the magnetic ring. However, in this structure, because the second clamping unit cooperates with the winding device and the wire hooking device to wind the second wire, the first wire is already wound on the magnetic ring. This results in the wire hooking device pulling the second wire downward in the center hole of the magnetic ring, which can easily cause the end of the second wire to scrape against the first wire that is already wound on the magnetic ring. This can easily damage the first wound wire, thereby causing damage to the product, that is, a decrease in the product yield.

[0005] Therefore, there is a need to improve the existing technology. Utility Model Content

[0033] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0034] like Figures 1-11 As shown, a cross winding machine that can prevent the wire wound on the magnetic ring from being scratched includes a frame 1 and a first rotating clamping unit 2, a second rotating clamping unit 3, a winding mechanism 4, a wire hooking mechanism 5 and a material grabbing robot 6 respectively installed on the frame 1.

[0035] Among them, the first rotating clamping unit 2 includes a first wire feeding and cutting mechanism (not marked in the figure) and a first rotating clamping mechanism (not marked in the figure); the first rotating clamping unit 2 can be used to cooperate with the winding mechanism 4 for winding and the wire hooking mechanism 5 for hooking on the first side of the magnetic ring to complete the winding of the first wire.

[0036] The second rotary clamping unit 3 includes a second wire feeding and cutting mechanism 31, a second rotary clamping mechanism 32 and a wire blocking mechanism 34 that cooperate with each other; the second rotary clamping unit 3 can be used to cooperate with the winding mechanism 4 for winding and the wire hooking mechanism 5 for hooking the wire on the second side of the magnetic ring to complete the winding of the second wire.

[0037] Therefore, two magnetic rings can be processed simultaneously using two clamping units.

[0038] The second rotating clamping mechanism 32 includes a clamping device 321 for clamping the magnetic ring, a flipping assembly connected to the clamping device 321 and used to drive the magnetic ring to flip along its diameter, and a rotating assembly connected to the flipping assembly and used to drive the magnetic ring to rotate. Therefore, the flipping assembly can be used to drive the magnetic ring to flip, while the rotating assembly can be used to drive the magnetic ring to rotate, thereby enabling convenient and quick position adjustment.

[0039] like Figure 1-Figure 4 as well as Figure 9 As shown, the wire blocking mechanism 34 includes a wire blocking plate 341 located below the clamping device 321 and a wire blocking driving device 342 for driving the wire blocking plate 341 to move up and down. The wire blocking plate 341 can be used to limit the second wire on the magnetic ring when the wire hooking mechanism 5 hooks the second wire, so as to prevent the second wire from scratching the first wire that has been wound on the magnetic ring during the process of being pulled downward. That is, the arrangement of the wire blocking mechanism 34 can well protect the wound wire.

[0040] The second wire feeding and cutting mechanism 31 can be used for feeding and cutting wires; the material grabbing robot 6 can be used for loading, transferring and unloading the magnetic ring.

[0041] like Figure 1-Figure 4 as well as Figure 9 As shown, preferably, an arc-shaped slot 343 corresponding to the center hole of the magnetic ring is provided on the side of the wire blocking plate 341 facing the winding mechanism 4, so that the second wire can be embedded in the arc-shaped slot 343, thereby better limiting the position of the wire, so that the second wire is not likely to scrape the wound first wire or the magnetic ring when it descends. Specifically, the arc-shaped slot 343 is located directly below the output end of the wire blocking drive device 342.

[0042] In this embodiment, the wire blocking driving device 342 is a cylinder, so that the wire blocking plate 341 can be easily raised and lowered.

[0043] In this embodiment, the clamping device 321 is a finger cylinder, so that the magnetic ring can be clamped conveniently.

[0044] like Figure 4-Figure 6 As shown, in this embodiment, the flip assembly includes a flip motor 322 and a gear transmission assembly 323 connected to the output shaft of the flip motor 322. The output end of the gear transmission assembly 323 is connected to the clamping device 321. Therefore, the flip motor 322 can conveniently drive the clamping device 321 through the gear transmission assembly 323 to flip the magnetic ring.

[0045] like Figure 4-Figure 6As shown, in this embodiment, the rotating assembly includes a positioning plate 324, an arc-shaped slide rail 325 and a rotating motor 326; an inner arc-shaped slide groove 327 and an outer arc-shaped slide groove 328 are respectively provided on the inner wall and outer wall of the arc-shaped slide rail 325; an inner pulley 329 and an outer pulley 330 are respectively provided in the inner arc-shaped slide groove 327 and the outer arc-shaped slide groove 328, and the inner pulley 329 and the outer pulley 330 are both installed at the bottom of the positioning plate 324; the gear transmission assembly 323 and the flip motor 322 are respectively installed on the top surface of the positioning plate 324; the rotating motor 326 is installed on the top surface of the positioning plate 324 and its output shaft is connected to the gear 331, and an arc-shaped rack 332 meshing with the gear 331 and connected to the frame 1 is also provided on the outer side of the arc-shaped slide rail 325. Therefore, after the above-mentioned setting, the rotating motor 326 can be used to drive the gear 332 to drive the positioning plate 324 to rotate along the arc-shaped rack 332, and synchronously drive the clamping device 321 to rotate; in addition, during the movement of the positioning plate 324, the inner arc-shaped groove 327 and the inner pulley 329 and the outer arc-shaped groove 328 and the outer pulley 330 can be used to enhance the stability of the positioning plate 324 during movement.

[0046] like Figure 4-Figure 6 As shown, in order to further enhance the stability of the positioning plate 324 , an arcuate groove 333 is also provided on the outer wall of the arcuate rack 332 ; a roller 334 matching the arcuate groove 333 is also installed at the bottom of the positioning plate 324 .

[0047] like Figure 7-Figure 8As shown, the winding mechanism 4 includes a front and rear winding motor 41 installed on the frame 1, a front and rear winding screw rod 42 installed on the output shaft of the front and rear winding motor 41 and extending forward and backward, a front and rear winding slide 43 installed on the front and rear winding screw rod 42 movably installed forward and backward, a winding upper and lower screw rod 44 installed on the front and rear winding slide 43 and extending up and down, a winding upper and lower motor 45 installed on the front and rear winding slide 43 and connected to the winding upper and lower screw rod 44, a winding upper and lower slide 46 installed on the winding upper and lower slide 46 movably installed on the winding upper and lower screw rod 44, a winding left and right motor 47 installed on the winding upper and lower slide 46, and two winding wheels 48 respectively connected to the winding left and right motors 47 and driven by the winding left and right motors 47 to move left and right; the two winding wheels 48 can be used to simultaneously guide the ends of the two wires above the two magnetic rings so that they can be hooked by the wire hooking mechanism 5 at the same time. Therefore, the front and rear winding motor 41 can drive the two winding reels 48 to move forward and backward, the upper and lower winding motor 45 can drive the winding reels 48 to move up and down, and the left and right winding motor 47 can drive the winding reels 48 to move left and right. The corresponding motors can simultaneously drive the two winding reels 48 to perform various corresponding actions, thereby simultaneously processing the magnetic rings on the first rotating clamping unit 2 and the second rotating clamping unit 3. Since the structure of the winding mechanism 4 described above belongs to the prior art, it will not be described in detail here.

[0048] like Figure 10 As shown, the wire hooking mechanism 5 includes a wire hooking motor 51 mounted on the frame 1, a wire hooking transmission assembly 52 connected to the output shaft of the wire hooking motor 51, and two hooking needles 53 mounted on the output end of the wire hooking transmission assembly 52 so as to be movable up and down; the hooking needles 53 can be used to penetrate the magnetic ring and pull the wire downward. Therefore, the wire hooking motor 51, in conjunction with the wire hooking transmission assembly 52, can be used to drive the two hooking needles 53 to move up and down synchronously, so as to simultaneously perform wire hooking operations on the magnetic rings on the first rotating clamping unit 2 and the second rotating clamping unit 3. In addition, the above-mentioned wire hooking mechanism 5 is also a prior art, and therefore, it will not be described in detail here.

[0049] The gripping robot 6 is a three-claw robot, i.e., it has three grippers. The first gripper is used to place the magnetic ring onto the first rotating clamping mechanism (i.e., loading the material). The second gripper is used to grab the magnetic ring with the first wire wound around it from the first rotating clamping mechanism and transfer it to the second rotating clamping mechanism 31. The third gripper is used to grab the magnetic ring with the second wire wound around it from the second rotating clamping mechanism 31 and unload it.

[0050] Since the structures of the second thread feeding and cutting mechanism 31 and the material grabbing robot 6 are both existing technologies, they will not be described in detail here.

[0051] Specifically, for the first rotary clamping unit 2, the first wire feeding and cutting mechanism and the first rotary clamping mechanism provided therein have the same structure and function as the second wire feeding and cutting mechanism 31 and the second rotary clamping mechanism 32 respectively. However, since the first rotary clamping unit 2 is used to wind the first wire, there is no need to set a wire blocking mechanism in the first rotary clamping unit 2.

[0052] Combine Figure 11 Specifically, when in use, the gripper of the material grabbing manipulator 6 is used to deliver the magnetic ring to the first rotary clamping mechanism of the first rotary clamping unit 2, that is, loading the material. After the first wire feeding and cutting mechanism supplies the wire, the first rotary clamping unit 2 cooperates with the winding mechanism 4 and the wire hooking mechanism 5 to complete the winding of the wire on the first side of the magnetic ring and complete the wire cutting in the middle, thereby completing the winding of the first wire.

[0053] Next, the gripping manipulator 6 delivers the magnetic ring with the first wire wound around it to the second rotating clamping unit 3 and is clamped by the clamping device 321 with the second side of the magnetic ring not wound facing the winding mechanism 4, i.e., the magnetic ring is transferred.

[0054] Next, the wire blocking drive device 342 drives the wire blocking plate 341 to rise to a preset position, specifically, the arc-shaped slot 343 is located below the center hole of the magnetic ring and in front of the first wound wire;

[0055] Next, the second thread feeding and cutting mechanism 31 feeds the thread;

[0056] Next, when the hook needle 53 of the hooking mechanism 5 is pulling the second wire downward, the wire blocking plate 341 can be used to block the second wire. Specifically, the wire blocking plate 341 is used to keep the second wire away from the first wire to prevent it from scratching the first wound wire.

[0057] Next, the winding mechanism 4 guides the second wire upward to a preset position above the magnetic ring by moving the winding wheel 48 up and down and forward and backward. Then, the winding left and right motors 47 drive the winding wheel 48 to move a certain distance in the direction of the hook needle 53. At the same time, the rotating motor 326 continues to drive the magnetic ring to rotate. Then, the hooking mechanism 5 and the winding mechanism 4 continue to operate until half of the second side of the magnetic ring is wound.

[0058] Next, the wire blocking drive device 342 drives the wire blocking plate 242 to descend, and the second wire feeding and cutting mechanism 31 cuts the wire, then the flip motor 322 drives the magnetic ring to flip, and then the wire blocking drive device 342 continues to drive the wire blocking plate 242 to rise to the preset position;

[0059] Next, the remaining portion of the second wire is wound around the other half of the second side of the magnetic ring through the cooperation of the second rotating clamping mechanism 32, the winding mechanism 4 and the hooking mechanism 5; then, each mechanism is reset;

[0060] Next, the material-grabbing robot 6 delivers the magnetic ring with the wire wound around it to the next process, namely unloading.

[0061] To sum up, the utility model sets a wire blocking mechanism 34 in the second rotating clamping unit 3, so that the first wire that has been wound on the magnetic ring can be protected during the winding process to prevent it from being scratched by the second wire during the winding process. That is, the wire blocking plate 341 is used to prevent the first wire that has been wound from being easily damaged, thereby improving the product yield.

[0062] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
