At the same time, the settings of the wire clamping mechanism and the wire cutting mechanism also make the entire winding work more coherent. After completing a round of coil winding work, the winding device can quickly use the second clamping point of the wire harness as the starting end point to carry out the next round of coil winding work, further improving the winding efficiency of the coils.

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the preferred embodiment of the utility model provides an auxiliary winding structure of a distributed winding machine, which is used to assist a winding device 3 in winding a coil, and includes a wire hooking device 1 and a wire clamping device 2 arranged on the machine platform;

[0032] The wire hooking device 1 comprises a first driving mechanism 11, a first fixing mechanism 12 and a cycloidal mechanism 13; the end of the first driving mechanism 11 is connected to the first fixing mechanism 12, and the first driving mechanism 11 is used to drive the first fixing mechanism 12 to move in space; the first fixing mechanism 12 is used to clamp the first clamping point of the wire harness to facilitate the winding device 3 to wind the second set of coils; the cycloidal mechanism 13 is arranged below the first fixing mechanism 12, and the cycloidal mechanism 13 is used to pull the wire harness away from the first fixing mechanism 12 after the second set of coils are wound;

[0033] The wire clamping device 2 includes a second driving mechanism 21, a wire clamping mechanism 23 and a wire cutting mechanism 22; the second driving mechanism 21 is used to drive the wire clamping mechanism 23 and the wire cutting mechanism 22 to approach or move away from the wire hooking device 1; the wire cutting mechanism 22 is arranged on the side of the wire clamping mechanism 23 away from the wire hooking device 1, and the wire cutting mechanism 22 is used to cut the wire harness after the second group of coils are wound, and the wire clamping mechanism 23 is used to clamp and fix the second clamping point to facilitate the wire winding device 3 to perform a new round of coil winding;

[0034] Among them, a round of coil winding work includes two groups of coils to be wound. The first clamping point is located on the wire harness between the two groups of coils in a round of coil winding work, and the second clamping point is located on the wire harness that is still connected to the wire winding device 3 after the wire harness is cut. The second clamping point and the first clamping point are respectively the fixed points of one end of the wire harness when the two groups of coils are wound in a round of coil winding work, and the other end of the wire harness is arranged on the wire winding device 3 for coil winding.

[0035] Specifically, in the winding device, a winding device 3 and a turntable 4 device are provided on the machine table. A plurality of wire dropping cups 41 are provided on the turntable 4 device to carry the wound coils. When performing a round of coil winding work, one end of the wire harness is fixed at the wire clamping mechanism 23, and the other end extends to the wire bin through the winding device 3. When the winding device 3 rotates, it can continuously guide the wire harness in the wire bin to the winding die of the winding device 3 to form a coil. The pressing mechanism of the winding device 3 presses the wound coil on the winding die onto the wire dropping cup 41, finally forming a complete set of coils. When the winding device 3 completes the winding work of the first set of coils according to the above steps, the first driving mechanism 11 drives the first fixing mechanism 12 to move and approach the winding device 3 until the wire harness on one side of the winding device 3 falls into the first fixing mechanism 12 and is clamped and fixed. This clamping point is the first clamping point. At the same time, the wire clamping mechanism 23 releases the original end of the wire harness. The turntable 4 rotates to remove the wire dropping cup 41 that has carried the first set of coils and moves a new wire dropping cup 41 to the working position. The winding device 3 rotates in the reverse direction with the first clamping point as the starting end point of the second set of coils to wind the second set of coils. The second set of coils wound on the wire dropping die is pressed onto the new wire dropping cup 41 by the pressing mechanism, and then the second driving mechanism 21 drives the wire clamping mechanism 23 and the wire cutting mechanism 22 to move, so that the wire harness on the side close to the winding device 3 falls into the wire clamping mechanism 23 and the wire cutting mechanism 22 at the same time. Subsequently, the wire cutting mechanism 22 cuts off the wire harness, and the wire clamping mechanism 23 clamps the wire harness on the side close to the winding device 3, that is, the second clamping point. The other end of the wire harness that has been cut off moves with the rotation of the turntable 4 and is moved to other places together with the second set of coils. At this time, the winding device 3 can use the second clamping point as the starting point for winding the first set of coils in a new round of coil winding work. In this embodiment, when the coil is being wound, the wire harness is quickly clamped and fixed by the wire hooking device 1, and with the first clamping point as the starting end point and in cooperation with the reverse rotation of the winding device 3, the winding device 3 can continuously wind two sets of coils, reducing the process of repeatedly cutting and clamping the wire harness, and improving the efficiency of coil winding; further, the wire cutting mechanism 22 and the clamping mechanism are arranged together. After the wire cutting mechanism 22 cuts off the wire harness, the clamping mechanism can quickly clamp the end of the wire harness on the side close to the winding device 3 to form the second clamping point. Relying on the second clamping point as the starting end point, the winding device 3 can quickly wind the first set of coils in a new round of coil winding work, making the switching between multiple rounds of coil winding work more coherent and smooth, and further improving the efficiency of coil winding. Among them, the first driving mechanism 11 can quickly drive the first fixing mechanism 12 to move in space, so as to accurately clamp and fix the wire harness on the side close to the winding device 3 to form the first clamping point. The first fixing mechanism 12 moves more quickly and accurately, and the coil winding efficiency is higher.

[0036] Furthermore, when winding the first group of coils, the winding device 3 rotates counterclockwise, and when winding the second group of coils, the winding device 3 rotates clockwise.

[0037] As Figure 3 shown, in some embodiments, the first driving mechanism 11 includes a first displacement module, a second displacement module, and a third displacement module connected in sequence. The displacement paths of the output ends of the first displacement module, the second displacement module, and the third displacement module are perpendicular to each other. The first displacement module is fixed to the machine table through a first mounting frame 111, and the output end of the third displacement module is connected to a first fixing mechanism 12.

[0038] Specifically, the displacement paths of the output ends of the first displacement module, the second displacement module, and the third displacement module are perpendicular to each other, which enables the first driving mechanism 11 to quickly and accurately control the position of the first fixing mechanism 12 in space, so that the first fixing mechanism 12 can quickly and accurately clamp the wire harness, thereby improving the wire harness transition efficiency and also improving the coil winding efficiency.

[0039] Further, in some embodiments, the first displacement module includes a first driving motor 112 disposed on the first mounting frame 111. The output end of the first driving motor 112 is connected to a first lead screw 113. The middle of the first lead screw 113 is connected to a second mounting frame 114. The first driving motor 112 is used to drive the second mounting frame 114 to move along the Y direction;

[0040] The second displacement module includes a first driving cylinder 115 whose output end is connected to the second mounting frame 114. The first driving cylinder 115 is fixedly connected to a third mounting frame 116. The third mounting frame 116 is slidably connected to the machine table. The first driving cylinder 115 is used to drive the third mounting frame 116 to move along the Z direction;

[0041] The third displacement module includes a second driving cylinder 117 fixed to the third mounting frame 116. The output end of the second driving cylinder 117 is connected to a first fixing mechanism 12. The second driving cylinder 117 is used to drive the first fixing mechanism 12 to move along the X direction.

[0042] Specifically, the first driving motor 112 on the first mounting bracket 111 drives the first lead screw 113 to rotate, and the first lead screw 113 drives the second mounting bracket 114 to move in the Y direction. The bottom of the second mounting bracket 114 is connected to the output end of the first driving cylinder 115. When the first driving cylinder 115 operates, it can cause the cylinder body of the first driving cylinder 115 to move in the Z direction away from or close to the second mounting bracket 114. The cylinder body of the first driving cylinder 115 is connected to the third mounting bracket 116, so that the third mounting bracket 116 can be driven to move up and down in the Z direction. A second driving cylinder 117 is installed on the third mounting bracket 116 in the X direction. The output end of the second driving cylinder 117 is connected to the first fixing mechanism 12. Under the control of the second driving cylinder 117, the first fixing mechanism 12 can move in the X direction. By the first driving motor 112, the first driving cylinder 115 and the second driving cylinder 117, the position of the first fixing mechanism 12 in space can be quickly adjusted, with a faster response and able to reach the clamping position faster to clamp and fix the wire harness. In a preferred embodiment, the second driving cylinder 117 is a double-stroke cylinder; in a second preferred embodiment, the third displacement module uses a structure of a driving motor cooperating with a lead screw to adjust the position of the first fixing mechanism 12 in the X direction.

[0043] In some embodiments, the first fixing mechanism 12 includes a fourth mounting bracket 121 connected to the output end of the third displacement module. The fourth mounting bracket 121 is provided with a third driving cylinder 122 and a sliding groove 123. One end of the sliding groove 123 facing the wire winding device 3 is provided with a first clamping block 124. The output end of the third driving cylinder 122 is connected to a second clamping block 125. The second clamping block 125 moves in the sliding groove 123 in the X direction to approach or move away from the first clamping block 124.

[0044] Specifically, when the winding of the first group of coils is completed, the first displacement module, the second displacement module and the third displacement module quickly drive the first fixing mechanism 12 to move to its working position. At this time, one end of the wire harness is connected to the first group of coils on the wire dropping cup 41, and the other end is connected to the wire winding device 3. The middle part of the wire harness falls on the sliding groove 123 between the first clamping block 124 and the second clamping block 125. Then the third driving cylinder 122 drives the second clamping block 125 to slide in the sliding groove 123 in the X direction, and the second clamping block 125 abuts against the first clamping block 124, thereby clamping and fixing the wire harness. The position clamped by the first clamping block 124 and the second clamping block 125 at this time is the first clamping point on the wire harness. Then the turntable 4 moves a new wire dropping cup 41 to the working position, and the wire winding device 3 starts to rotate clockwise to wind the second group of coils.

[0045] In some embodiments, the cycloid mechanism 13 includes a fourth driving cylinder 131 provided on the fourth mounting bracket 121. The output end of the fourth driving cylinder 131 is connected to a rotating plate 132. The rotating plate 132 is rotatably connected to the side plate of the sliding groove 123. On the side of the rotating plate 132 away from the fourth driving cylinder 131, there is a "U"-shaped wire-pushing lever. The fourth driving cylinder 131 drives the rotating plate 132 to rotate around an axis extending in the Y direction, driving the wire-pushing lever 133 to rotate and push out the wire harness.

[0046] Specifically, when the winding of the second group of coils in a round of coil winding work is also completed and the wire-cutting mechanism 22 has cut the wire harness, at this time, the fourth driving cylinder 131 drives the edge part of the fan-shaped rotating plate 132, causing the rotating plate 132 to rotate around its axis. At this time, the wire-pushing baffle on the other side of the rotating plate 132 is driven to move upward, thereby pushing out the wire harness located between the first clamping block 124 and the second clamping block 125, facilitating the next round of coil winding work of the winding device 3. The cycloid device uses a cylinder as the power source and rotates to push out the wire harness from the first fixing mechanism 12. Its action response is more rapid, enabling a smoother and more coherent switch between two rounds of coil winding work, and naturally, the winding efficiency of the coils is higher.

[0047] As Figures 4 to 5 shown, in some embodiments, the second driving mechanism 21 includes a first mounting plate 211 connected to the machine table. The first mounting plate 211 is provided with a second driving motor 212. The output end of the second driving motor 212 is connected to a second lead screw 213 extending in the X direction. The second lead screw 213 is connected to a second mounting plate 214. The second mounting plate 214 is slidably connected to the first mounting plate 211, and the second mounting plate 214 is fixedly connected with a wire-clamping mechanism 23 and a wire-cutting mechanism 22.

[0048] Specifically, the second driving motor 212 can drive the wire-clamping mechanism 23 and the wire-cutting mechanism 22 on the second mounting plate 214 to move in the X direction away from or towards the winding device 3. After the winding of the second group of coils in a round of coil winding work is completed, one end of the wire harness is connected to the second group of coils on the wire-drop cup 41, and the other end is connected to the winding device 3. Subsequently, the winding device 3 rotates counterclockwise. The second driving mechanism 21 drives the second mounting plate 214 away from the winding device 3. The wire harness on one side of the winding device 3 is successively caught in the wire-cutting mechanism 22 and the wire-clamping mechanism 23. Subsequently, the wire-cutting mechanism 22 cuts the wire harness. After cutting, the wire harness on the side close to the second group of coils is transferred away together with the second group of coils by the turntable 4 structure, while the wire harness on the side close to the winding device 3 is clamped by the clamping mechanism, that is, the second clamping point. Based on this, the winding device 3 rotates counterclockwise again to wind the first group of coils in the new round of coil winding work.

[0049] In some embodiments, the second driving mechanism 21 further includes a third mounting plate 215. The third mounting plate 215 is fixedly connected to the machine table. A fifth driving cylinder 216 is mounted on the third mounting plate 215. The fifth driving cylinder 216 is connected to the first mounting plate 211 and is used to drive the first mounting plate 211 to move in the Z direction.

[0050] Specifically, the fifth driving cylinder 216 fixedly connected to the machine table through the third mounting plate 215 can drive the wire clamping mechanism 23 and the wire cutting mechanism 22 to move up and down in the Z direction through the first mounting plate 211, so as to better adjust the positions of the wire clamping mechanism 23 and the wire cutting mechanism 22, enabling the wire harness to be better clamped between the wire clamping mechanism 23 and the wire cutting mechanism 22, and then completing the subsequent wire cutting action and wire clamping action.

[0051] In some embodiments, the wire cutting mechanism 22 includes a sixth driving cylinder 221 and a wire cutting bottom knife 222 provided on the second mounting plate 214. The output end of the sixth driving cylinder 221 passes through the wire cutting bottom knife 222 and is connected to an upper scissors plate 223. The sixth driving cylinder 221 drives the upper scissors plate 223 to move downward to fix the wire harness between the wire cutting bottom knife 222 and the upper scissors plate 223 and cut it.

[0052] Furthermore, the wire clamping mechanism 23 includes a protrusion 231 and a cushion block 232 arranged oppositely. The cushion block 232 is arranged on the side of the wire cutting bottom knife 222 close to the thread hooking device 1 and faces the upper scissors plate 223, and the protrusion 231 is correspondingly arranged on the side of the upper scissors plate 223 facing the wire cutting bottom knife 222.

[0053] Still further, the wire clamping device 2 further includes a guiding mechanism 24. The guiding mechanism 24 includes a guide wheel 241 arranged on the side of the upper scissors plate 223 away from the thread hooking device 1. The guide wheel 241 is rotatably connected to the upper scissors plate 223.

[0054] Specifically, after the winding of the second group of coils is completed, the winding device starts to rotate counterclockwise. At the same time, the fifth driving cylinder 216 and the second driving motor 212 start to adjust the positions of the wire clamping mechanism 23, the wire cutting mechanism 22, and the guiding mechanism 24 until the guide wheel 241 in the guiding mechanism 24 contacts the wire harness. Then, the second driving motor 212 drives the second mounting plate 214 to move away from the winding device 3 in the X direction. The wire harness on the side of the winding device 3 is sequentially clamped between the bottom wire cutting knife 222 and the upper scissors plate 223 under the guiding action of the guide wheel 241. The bottom wire cutting knife 222 is a block structure fixed on the second mounting plate 214, and a cutting edge is provided on the side facing the upper scissors plate 223. A cutting edge can also be provided on the side of the upper scissors plate 223 facing the bottom wire cutting knife 222. After the wire harness is properly clamped, the sixth driving cylinder 221 drives the upper scissors plate 223 to move downward in the Z direction, and the upper scissors plate 223 approaches the bottom wire cutting knife 222 until the wire harness is cut. At the same time, a cushion block 232 is provided on the side of the bottom wire cutting knife 222 close to the wire hooking device 1, and a spring is provided at the bottom of the cushion block 232. The upper scissors plate 223 is provided with a protrusion 231 corresponding to the cushion block 232. When the sixth driving cylinder 221 drives the upper scissors plate 223 to move downward, the protrusion 231 and the cushion block 232 will clamp and fix the end of the wire harness. The wire harness here is the second clamping point. Based on the second clamping point, the winding device 3 starts to rotate counterclockwise to wind the first group of coils in a new round of coil winding work.

[0055] In summary, the embodiment of the utility model provides an auxiliary winding structure of a distributed winding machine. When the coil winding work is performed, one end of the wire harness is clamped and fixed by the protrusion 231 and the pad 232 at the clamping mechanism, and the other end extends to the wire bin through the winding device 3. The rotation of the winding device 3 can continuously guide the wire harness in the wire bin to the winding mold of the winding device 3 to form a coil. The pressing mechanism of the winding device 3 presses the coil wound on the winding mold down to the wire drop cup 41, and finally forms a complete set of coils. After the winding device 3 completes the winding of the first set of coils according to the above steps, the first displacement module, the second displacement module and the fourth mounting frame 121 of the third displacement module in the first driving mechanism 11 move so that the slide slot 123 is close to the winding device 3 until the wire harness on one side of the winding device 3 falls into the slide slot 123 between the first clamping block 124 and the second clamping block 125. Then, the third driving cylinder 122 drives the second clamping block 125 to move toward the direction of the first clamping block 124 and clamp the wire harness. This clamping point is the first clamping point. The sixth driving cylinder 221 will drive the upper scissor plate 223 to move upward, and the protrusion 231 will separate from the pad 232, loosening the original end of the wire harness that was originally clamped and fixed by the clamping mechanism. The turntable 4 rotates to remove the wire drop cup 41 that has already carried the first group of coils and move the new wire drop cup 41 to the working position. The winding device 3 rotates clockwise with the first clamping point as the starting end point of the second group of coils to wind the second group of coils. The pressing mechanism presses the second group of coils down to the new wire drop cup 41 to complete the winding of the second group of coils. Then the winding device 3 rotates counterclockwise again, and at the same time, the second driving motor 212 and the fifth driving cylinder 216 begin to adjust the positions of the guiding mechanism 24, the wire cutting mechanism 22 and the clamping mechanism, and guide the wire harness to between the wire cutting bottom knife 222 and the upper scissor plate 223 through the guide wheel 241 in the guiding mechanism 24, and the sixth driving cylinder 221 drives the upper scissor plate 223 to move downward along the Z direction to cut the wire harness, and at the same time, the protrusion 231 and the cushion block 232 approach again and clamp the wire harness close to one side of the winding device 3, which is the second clamping point. At this time, the third driving cylinder 122 drives the second clamping block 125 away from the first clamping block 124, and the wire harness at the first clamping point is released. The fourth driving cylinder 131 also drives the wire shifting lever 133 to rotate through the rotating plate 132, and the wire harness located on the slide slot 123 is shifted out from the slide slot 123, and the second group of coils is moved to other places in conjunction with the rotation of the turntable 4. At this time, a round of coil winding work is completed. Then the winding device 3 takes the second clamping point as the initial end point and performs the winding of the first group of coils in a new round of coil winding work.

[0056] In the present utility model, when the coil is being wound, the wire harness is quickly clamped and fixed by the wire hooking device 1, and with the first clamping point as the starting end point, the wire winding device 3 rotates in the reverse direction, enabling the wire winding device 3 to continuously wind two groups of coils, reducing the process of repeatedly cutting and clamping the wire harness, and improving the efficiency of coil winding; furthermore, the wire cutting mechanism 22 and the clamping mechanism are arranged together. After the wire cutting mechanism 22 cuts the wire harness, the clamping mechanism can quickly clamp the end of the wire harness close to the wire winding device 3 to form a second clamping point. Relying on the second clamping point as the starting end point, the wire winding device 3 can quickly carry out the winding of the first group of coils in a new round of coil winding work, making the switching between multiple rounds of coil winding work more coherent and smooth, and further improving the efficiency of coil winding. Among them, the third moving module is driven by a cylinder, which can quickly drive the first fixing mechanism 12 to move in space, thereby accurately and quickly clamping and fixing the wire harness close to the wire winding device 3 to form a first clamping point, and the coil winding efficiency is higher.

[0057] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
