Detailed implementation manners

[0020] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] As Figures 1 to 9 shown, a wire transfer device of the present invention includes a fixed base 10, a moving mechanism 20, a rotating mechanism 30, a grasping mechanism 40 and a hooking mechanism 50. The moving mechanism 20 is arranged on the fixed base 10 and moves along the fixed base 10. The rotating mechanism 30 is installed on the moving mechanism 20. The grasping mechanism 40 is connected to the rotating mechanism 30, and the rotating mechanism 30 drives the grasping mechanism 40 to rotate. The hooking mechanism 50 is connected to the rotating mechanism 30, and the rotating mechanism 30 drives the hooking mechanism 50 to rotate. The coils wound by the jig and the coils wound by the wire rack 11 are respectively grasped by the grasping mechanism 40 and the hooking mechanism 50, improving the flexibility of the device and enabling it to be adaptively adjusted according to different winding methods. Then, through the cooperation of the rotating mechanism 30 and the moving mechanism 20, the wound coils are transferred to the designated position, facilitating the next process.

[0022] As Figure 9 shown, in this embodiment, the length of the fixed base 10 can be adaptively adjusted according to the actual situation. On both sides of the fixed base 10, there are also a wire winding mechanism 60, a wire rack loading mechanism 70, a wire rack unloading mechanism 80 and a jig loading and unloading mechanism 90. The grasping mechanism 40 grasps the jig from the jig loading and unloading mechanism 90, and then moves the jig to the wire winding mechanism 60 through the moving mechanism 20 and the rotating mechanism 30. After wire winding is completed, the jig is transported back to the jig loading and unloading mechanism 90 for the next process. Similarly, the hooking mechanism 50 hooks the wire rack 11 from the wire rack loading mechanism 70, and then moves the wire rack 11 to the wire winding mechanism 60 through the moving mechanism 20 and the rotating mechanism 30. After wire winding is completed, the wire rack 11 is transported back to the wire rack unloading mechanism 80 for the next process.

[0023] In the present invention, the wire winding mechanism 60, the wire rack loading mechanism 70, the wire rack unloading mechanism 80, the jig loading and unloading mechanism 90 and the bundling and packaging mechanism 100 are all prior arts, so no further description will be made here.

[0024] The moving mechanism 20 includes a moving frame 21, a moving platen 22, a moving motor 23, a moving gear 24, a moving slider 25, a moving slide rail 26, and a moving rack 27.

By driving the moving gear 24 to rotate through the moving motor 23, due to the meshing of the moving gear 24 and the moving rack 27, the moving platen 22 is driven to move along the moving slide rail 26 through the moving slider 25, thereby realizing the movement of the moving mechanism 20.

[0025] The rotating mechanism 30 is arranged on the moving mechanism 20 and moves simultaneously with the moving mechanism 20. The rotating mechanism 30 includes a rotating motor 31, a rotating gear 32, a slewing bearing 33, and a rotating table 34.

The first lifting module 41 is installed on the rotating table 34, the first lifting module 41 is connected to the grasping module 42, the first lifting module 41 is used to drive the grasping module 42 to lift, and the grasping module 42 is used to grasp the coil.

[0029] In this embodiment, there are two grasping mechanisms 40, which are respectively arranged at both ends of the rotating table 34. During use, first, the moving mechanism 20 drives the grasping mechanism 40 to move to the position of the jig loading and unloading mechanism 90.

Then, the moving mechanism 20 moves to the position of the appropriate wire winding mechanism 60, places the jig on the wire winding mechanism 60. After wire winding is completed, through the repeated steps, the grasping mechanism 40 grasps the coil wound on the jig and transports it to the jig loading and unloading mechanism 90 to complete loading and unloading. The jig after wire winding is finally moved to the bundling and packaging mechanism 100 by the jig loading and unloading mechanism 90 to complete bundling.

[0030] The first lifting module 41 includes a first driving cylinder 411, a first guide rod 412, a first guide seat 413, and a first lifting platform 414.

[0033] In this embodiment, there are also two hooking mechanisms 50, which are respectively arranged at both ends of the rotating table 34. During use, first, the moving mechanism 20 drives the hooking mechanism 50 to move to the position of the wire rack loading mechanism 70. Then, the second lifting module 51 controls the hooking module 52 to descend. When the hooking module 52 descends to an appropriate height, the moving mechanism 20 moves again to make the hooking module 52 hook the wire rack 11. The second lifting module 51 rises to lift the wire rack 11. Then, the fixing module 53 limits the wire rack 11 to prevent it from shaking. Then, the second lifting module 51 controls the hooking module 52 to rise. The rotating mechanism 30 rotates the rotating table 34. Then, the moving mechanism 20 moves to the position of the appropriate wire winding mechanism 60 and places the wire rack 11 on the wire winding mechanism 60.

Through the setting of the second guide rod 512, the stability of the second lifting module 51 during lifting is increased, and shaking is avoided, so as to ensure accurate hooking of the wire rack 11.

[0035] The hooking module 52 includes a wire rack table board 521 and a weighing sensor 522. The wire rack table board 521 is fixed on the second lifting platform 514.

By the relative and opposite movement of the two fixing frames 535, the clamping and loosening of the wire rack 11 are realized. Since the first connecting plate 532 and the second connecting plate 533 are hinged through the connecting rod 534, when the fixing cylinder 531 pushes the first connecting plate 532 to move, the connecting rod 534 drives the two second connecting plates 533 to move relatively, so that the two fixing frames 535 clamp the wire rack 11. When the fixing cylinder 531 retracts, the fixing cylinder 531 drives the first connecting plate 532 to move in the opposite direction, and the connecting rod 534 drives the two second connecting plates 533 to move in the opposite direction, so that the two fixing frames 535 loosen the wire rack 11.
