Description

Technical Field

[0001] The present invention relates to the technical field of winding machines, and more specifically, to a winding machine and a winding process. Background Art

[0002] A winding machine is a device that winds a linear object onto a specific workpiece, usually used for copper wire winding. Most electrical products need to be wound into an inductor coil with enameled copper wire (enameled wire for short), and a winding machine can be used to complete this one or more processes. Existing winding machines can generally only wind a copper wire continuously on an iron core. For products that need to be wound using a cross winding method, the current winding method is generally to first wind a copper wire on the iron core to form a semi-finished product, and then wind the semi-finished product through another winding machine, or manually adjust the position of the semi-finished product on the original winding machine to achieve winding of the copper wire on the same winding machine, thereby completing production. This production method is not coherent, and due to human interference in the winding process, the product quality cannot be well guaranteed. Therefore, it is necessary to develop a new winding machine to solve the above problems. Summary of the invention

[0017] A winding process includes loading, first winding, second winding and unloading, as follows:

[0018] Loading: The loading module arranges the cores in order, and the transport module transports the cores to the first winding module;

[0019] First winding: The rotary clamping mechanism rotates to the initial position, the first clamping cylinder clamps and fixes the iron core to be wound, and then the rotary clamping mechanism rotates to the working position, the first wire feeding module outputs the copper wire, and the copper wire passes through the iron core from top to bottom.

The wire hooking mechanism extends from bottom to top, hooks the copper wire above the iron core, and pulls it downward to wind the copper wire around the iron core. This is one winding operation.

[0025] Repeat the actions of the wire pulling mechanism and the wire hooking mechanism. During this process, each time a winding operation is performed, the rotating clamping mechanism drives the iron core to rotate an angle. After repeated winding operations, the copper wire is densely wound on the iron core.

[0027] In the first winding and the second winding, the core maintains its original horizontal state or flips 180° according to the winding requirements.

[0028] When the core only needs one continuous winding process, only the first winding process or the second winding process is performed, and the winding module that does not need to be wound serves as a transition station to hold the core or product.

[0029] When the core needs to be wound twice, both the first winding and the second winding need to be performed, and during the second winding, the core can be kept horizontal or flipped 180° according to the needs before the winding operation is performed.

[0059] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0061] The present invention provides a winding machine with a double-station structure to realize continuous production of products with different winding requirements. The winding machine includes a frame 1 and a feeding module 2, a wire supply module 4, a transport module 5 and a winding module 3 arranged on the frame 1. The number of the winding modules 3 and the number of the wire supply modules 4 are both two. Each winding module 3 corresponds to a wire supply module 4, forming a winding station.

[0062] The transport module 5 transports the iron core 7 from the feeding module 2 to the first winding module 3 to realize the winding of the copper wire on the half side of the iron core 7, and then the transport module 5 transports the iron core 7 to the second winding module 3 to realize the winding of the copper wire on the other half side of the iron core 7, and finally the iron core 7 with all the copper wires wound is transported out. It is easy to understand that the iron core 7 described in the present invention refers to a ring-shaped metal product, generally an iron product, which is the same as the iron core 7 in the prior art.

[0063] In the present invention, the winding module 3 includes a rotating clamping mechanism 31, a wire hooking mechanism 33 and a wire pulling mechanism 32. The iron core 7 is clamped and fixed by the rotating clamping mechanism 31, so that the iron core 7 is placed flat on the wire hooking mechanism 33, so that the hook needle 3303 of the wire hooking mechanism 33 passes through the iron core 7 to pull the copper wire down. The wire pulling mechanism 32 is located outside the iron core 7 and cooperates with the wire hooking mechanism 33 to realize the winding of the copper wire on the iron core 7. The structure of the winding module 3 of the present invention is specifically described below:

[0064] The structure of the rotating clamping mechanism 31 is various, as long as it can clamp the iron core 7 and control the iron core 7 to rotate about the axis of the iron core 7. For example, the rotating clamping mechanism 31 can adopt the device for clamping the iron core 7 of the existing winding machine.

[0065] Preferably, the present invention proposes a feasible rotating clamping mechanism 31. As shown in the figure, the rotating clamping mechanism 31 includes an upper base 3101, a connecting frame 3105, a rotating ring 3103, a first rotating motor 3104, a second rotating motor 3106 and a first clamping claw cylinder 3107. The upper base 3101 is arranged on the frame 1. The middle part of the upper base 3101 is vertically penetrated to form a cylindrical hook wire avoidance space 3102 connected to the bottom of the frame 1. The rotating ring 3103 is rotatably sleeved on the side of the upper base 3101 and connected to the hook wire avoidance space 3102. 02 coaxially, the first rotating motor 3104 is arranged on the outer side below the upper base 3101 and is connected to the rotating ring 3103 to drive the rotating ring 3103 to rotate on the side of the upper base 3101, the bottom end of the connecting frame 3105 is connected to the top surface of the rotating ring 3103, the second rotating motor 3106 is horizontally arranged on the top of the connecting frame 3105, the cylinder body of the first clamping jaw cylinder 3107 is connected to the transmission shaft of the second rotating motor 3106, and the clamping jaw part of the first clamping jaw cylinder 3107 is located directly above the hooking wire avoidance space 3102 of the upper base 3101. It is easy to understand that when the first clamping jaw cylinder 3107 clamps the iron core 7, the iron core 7 is located directly above the hooking wire avoidance space 3102, and the axis of the iron core 7 coincides with the axis of the hooking wire avoidance space 3102.

[0066] The working principle of the rotating clamping mechanism 31 is: the first clamping claw cylinder 3107 clamps the iron core 7 so that the iron core 7 is horizontally placed directly above the wire hooking avoidance space 3102; the first rotating motor 3104 drives the rotating ring 3103 to rotate, and through the connecting frame 3105, the first clamping claw cylinder 3107 rotates synchronously with the rotating ring 3103. Since the iron core 7 is coaxial with the rotating ring 3103 and the wire hooking avoidance space 3102, the iron core 7 actually rotates around its own axis. By controlling the rotation angle of the iron core 7 and cooperating with the wire hooking mechanism 33 and the wire pulling mechanism 32, regular winding of the copper wire can be achieved.

[0067] When producing inductor coils at double stations, the rotating clamping mechanism 31 at the second winding station can drive the first clamping cylinder 3107 to flip 180° through the second rotating motor 3106 according to the winding method, thereby turning over the iron core 7, and then cooperating with the wire hooking mechanism 33 and the wire pulling mechanism 32 to realize regular winding of the copper wire.

[0068] It is easy to understand that a sensor device such as a proximity switch for detecting movement into position can be set on the side of the rotating ring 3103 to monitor whether the rotating ring 3103 has rotated into position.

[0069] Furthermore, the rotating clamping mechanism 31 also includes a protective tube 3108, which is arranged on the upper base 3101 and is located below the first clamping jaw cylinder 3107. The protective tube 3108 is coaxial with the hook line avoidance space 3102, and the inner diameter of the protective tube 3108 is the same as the inner diameter of the hook line avoidance space 3102.

[0070] The structure of the wire hooking mechanism 33 is various, as long as it can realize the structure of pulling the copper wire from the outside to the inside and from the top to the bottom. For example, the wire hooking mechanism 33 can adopt the wire hooking device of the existing winding machine.

[0071] Preferably, the present invention proposes a feasible thread hooking mechanism 33, as shown in the figure, the thread hooking mechanism 33 includes a lower base, a screw lift 3301, a connecting block 3302 and a hook hook 3303, the lower base is arranged below the frame 1, the screw lift is fixedly connected to the lower base, the connecting block 3302 is connected to the screw lift 3301 to realize the vertical lifting of the connecting block 3302, the bottom end of the hook hook 3303 is fixedly connected to the connecting block 3302, and the hook hook 3303 is on the axis of the hook hook avoidance space 3102, and the top end of the hook hook 3303 is a fishhook-shaped hook end.

[0072] The working principle of the wire hooking mechanism 33 is: when the copper wire is placed horizontally above the iron core 7, the screw elevator 3301 drives the hook needle 3303 to rise, and the wire hooking end of the hook needle 3303 approaches the copper wire and continues to rise until the wire hooking end is completely above the copper wire, then the hook needle 3303 descends, and the copper wire enters the wire hooking end, and is then pulled downward until the copper wire is completely pulled through the inside of the iron core 7. At this time, the copper wire vertically passes through the iron core 7, and with the cooperation of the wire pulling mechanism 32, the copper wire is pulled from the inside to the outside and from the bottom to the top, and is placed horizontally above the iron core 7 again, thereby realizing one winding of the copper wire on the iron core 7.

[0073] When the protective tube 3108 is provided, the portion of the copper wire that is pulled down is in the protective tube 3108, which effectively prevents the copper wire from deviating and facilitates the contact between the wire pulling mechanism 32 and the copper wire.

[0074] The structure of the wire pulling mechanism 32 is various, as long as it can realize the structure of pulling the copper wire from the inside to the outside and from the bottom to the top. For example, the wire pulling mechanism 32 can adopt the wire pulling device of the existing winding machine.

[0075] Preferably, the present invention proposes a feasible wire pulling mechanism 32. As shown in the figure, the wire pulling mechanism 32 includes a deflection base 3201, a deflection motor 3202, a reciprocating base 3203, a reciprocating motor 3204 and a wire pulling assembly. The deflection base 3201 is rotatably arranged on the frame 1, on one side of the upper base 3101. The deflection motor 3202 is arranged below the frame 1 and connected to the deflection base 3201, driving the deflection base 3201 to rotate horizontally. The top surface of the deflection base 3201 extends upward to form a mounting vertical plate 3207, which is rotated to the left. The reciprocating motor 3204 and the reciprocating base 3203 are respectively arranged on the two side surfaces of the mounting vertical plate 3207. An eccentric block 3206 is arranged on the side of the reciprocating base 3203 facing the mounting vertical plate 3207. One end of the eccentric block 3206 is rotatably connected to the reciprocating base 3203. The transmission shaft of the reciprocating motor 3204 passes through the mounting vertical plate 3207 and is fixedly connected to the other end of the eccentric block 3206. The wire pulling assembly is horizontally arranged on the reciprocating base 3203, and the end of the wire pulling assembly facing the hook wire avoidance space 3102 is a hook-shaped wire pulling end.

[0076] It is easy to understand that when the wire pulling assembly is extended forward to the limit position, the wire pulling end exceeds the axis of the iron core 7. The working principle of the wire pulling assembly includes two steps: pulling out the copper wire and resetting the copper wire, which are as follows:

[0077] Since the reciprocating motor 3204 and the reciprocating base 3203 are connected by an eccentric piece, with the wire pulling assembly as a reference, the movement trajectory of the wire pulling assembly includes four trajectories that are performed in sequence. The first trajectory is: the wire pulling assembly extends forward to the extreme position, at which time the wire pulling assembly is below the iron core 7, and the wire pulling end exceeds the axis of the iron core 7, so that the copper wire in the middle of the iron core 7 is inside the wire pulling end; the second trajectory is: the wire pulling assembly retracts backward to the extreme position, during which the copper wire is below the iron core 7 and close to the iron core 7 and is pulled out of the iron core 7; the third trajectory is: the wire pulling assembly extends forward to the extreme position, at which time the wire pulling assembly is above the iron core 7, during which the part of the copper wire that is pulled out surrounds the wire pulling end and is brought above the iron core 7, and this part of the copper wire is placed horizontally above the iron core 7, waiting for the wire hooking assembly to hook all the copper wire that is not wrapped around the iron core 7 into the iron core 7; the fourth trajectory is: the wire pulling assembly retracts backward to the extreme position. It is easy to understand that after the wire pulling assembly completes the first and second sections of the trajectory, the step of pulling out the copper wire is completed, and after completing the third and fourth sections of the trajectory, the step of resetting the copper wire is completed.

[0078] In the first trajectory, before the wire pulling assembly is ready to extend forward, the deflection motor 3202 first controls the deflection base 3201 to rotate an angle so that the wire pulling end of the wire pulling assembly rotates in the direction away from the copper wire. When the wire pulling assembly moves forward to the extreme position, the deflection motor 3202 controls the deflection base 3201 to rotate in the opposite direction by the same angle so that the copper wire is inside the wire pulling end, thereby avoiding the situation where the copper wire is not pulled in the second trajectory.

[0079] In the third track, when the wire pulling assembly has moved forward to the limit position, the deflection motor 3202 controls the deflection base 3201 to rotate an angle, so that the wire pulling end of the wire pulling assembly rotates in the direction away from the copper wire. At this time, the wire pulling end moves the copper wire in the direction away from the axis of the hook needle 3303, which is equivalent to the copper wire avoiding the hook end of the hook needle 3303 during the rising process of the hook needle 3303. After the hook needle 3303 rises to the limit position, the deflection motor 3202 controls the deflection base 3201 to rotate in the opposite direction by the same angle, bringing the copper wire to the position where the hook end can hook the copper wire when the hook needle 3303 descends, and then the hook needle 3303 descends to pull the copper wire downward. After the fourth track, the wire pulling assembly resets and waits for the next cycle, that is, the first to fourth tracks are regarded as one cycle, and the cycle is repeated for multiple times. With the cooperation of the hook mechanism 33 and the rotating clamping mechanism 31, the copper wire is wound on the iron core 7 in an orderly manner as required. It is easy to understand that the hook needle 3303 pulls the copper wire downward, so that all the remaining unwound copper wire is pulled under the iron core 7, which is similar to the function of the wire hook assembly in the prior art. There will be no situation where the end of the copper wire does not pass through the iron core 7, causing the wire pulling assembly to pull two or even more sections of copper wire at the same time.

[0080] It is easy to understand that, since there is a need for the hook 3303 to rise and pass through the wire pulling end in the third trajectory, the space inside the wire pulling end is larger, which is convenient for the hook 3303 to pass through.

[0081] Furthermore, the wire pulling assembly includes a wire pulling member 3205 and a guide member 3208. As shown in the figure, the wire pulling member 3205 is horizontally arranged, and one end of the wire pulling member 3205 is connected to the top surface of the reciprocating base 3203, and the other end of the wire pulling member 3205 is facing the direction of the iron core 7, and a avoidance position 3209 is formed at the end. The guide member 3208 is arranged at the end of the wire pulling member 3205 facing the iron core 7. The guide member 3208 is in the avoidance position 3209, so that the end of the wire pulling member 3205 forms a hook-like structure, and an annular wire groove 3217 is arranged on the side of the guide member 3208. When the copper wire is driven, the copper wire enters the wire groove 3217. The wire groove 3217 has a limiting effect on the copper wire. When the wire pulling assembly is horizontally deflected, the wire groove 3217 will drive the copper wire to move together to prevent the copper wire from falling out.

[0082] Furthermore, the wire pulling assembly also includes a deflection limit assembly and a reciprocating limit assembly.

[0083] The deflection limit assembly includes a first proximity switch 3210 and a first detection piece 3211. The first proximity switch 3210 is arranged on the frame 1 and is located on one side of the deflection base 3201. The first detection piece 3211 is arranged on the side of the deflection base 3201 close to the first proximity switch 3210. The first proximity switch 3210 keeps detecting the first detection piece 3211. When the deflection base 3201 rotates and the first proximity switch 3210 cannot detect the first detection piece 3211, it means that the deflection angle is too large, that is, when the deflection base 3201 moves normally, the first proximity switch 3210 can always detect the signal of the first detection piece 3211.

[0084] The reciprocating limit assembly includes a second proximity switch 3212 and a second detection piece 3213. The second proximity switch 3212 is arranged on the deflection base 3201, close to the bottom surface of the reciprocating base 3203, and the second detection piece 3213 is arranged on the bottom surface of the reciprocating base 3203, facing the second proximity switch 3212. The function of the reciprocating limit assembly is to determine whether the reciprocating base 3203 has been lowered into place.

[0085] Furthermore, the wire pulling mechanism 32 further includes a guide assembly, which is arranged on the side of the mounting vertical plate 3207 facing the reciprocating base 3203, and includes a transverse guide rail 3216, a guide plate 3215 and a vertical guide rail 3214. The transverse guide rail 3216 is fixedly arranged on the side of the mounting vertical plate 3207, and the side of the guide plate 3215 facing the mounting vertical plate 3207 is slidably connected to the transverse guide rail 3216 through a transverse guide portion, and the vertical guide rail 3214 is vertically arranged on the side of the guide plate 3215 facing the reciprocating base 3203, and the side of the reciprocating base 3203 facing the mounting vertical plate 3207 is slidably connected to the vertical guide rail 3214 through a vertical guide portion. The rotation of the reciprocating base 3203 is decomposed into the transverse movement and vertical movement of the reciprocating base 3203 on the guide assembly, and the guide assembly is conducive to improving the stability of the movement of the reciprocating base 3203.

[0086] Furthermore, the winding module 3 also includes a limiting mechanism 34. As shown in the figure, the limiting mechanism 34 includes a fixed seat 3401, a second clamping jaw cylinder 3402 and two limiting plates 3403. The fixed seat 3401 is arranged between the deflection base 3201 and the upper base 3101, and the second clamping jaw cylinder 3402 is arranged on the fixed seat 3401. The two limiting plates 3403 are connected to the second clamping jaw cylinder 3402, and the second clamping jaw cylinder 3402 controls the synchronization. When approaching or moving away, a copper wire avoidance position 3404 is set on one side of the limiting plate 3403 facing the other limiting plate 3403, and the copper wire avoidance position 3404 is above the hook wire avoidance space 3102 and below the wire pulling member 3205. When the two limiting plates 3403 are close to each other, the two copper wire avoidance positions 3404 form a hook wire avoidance hole, and the hook wire avoidance hole is coaxial with the hook wire avoidance space 3102, and the inner diameter of the hook wire avoidance hole is larger than the outer diameter of the hook needle 3303.

[0087] It is easy to understand, in combination with the accompanying drawings, that when the upper base 3101 is provided with the protective tube 3108 , the two limiting pieces 3403 are both located above the protective tube 3108 .

[0088] The limiting mechanism 34 is used in conjunction with the winding of the copper wire. When the wire supply mechanism outputs the copper wire, the two limiting pieces 3403 are in a state of being away from each other. Before the operation of winding the copper wire begins, the two limiting pieces 3403 are close to each other, so that the copper wire is in a state of passing through the hook wire avoidance hole. In the subsequent winding operation, the two limiting pieces 3403 remain close to each other. When the hook wire mechanism 33 pulls the copper wire downward, the copper wire can only pass through the hook wire avoidance hole, that is, the limiting mechanism 34 ensures that the copper wire always remains in a relatively vertical state after being pulled down, effectively preventing the copper wire from shifting.

[0089] Based on the above winding module 3, the present invention also proposes a winding process, including loading, first winding, second winding and unloading, as follows:

[0090] Loading: The loading module 2 arranges the iron cores 7 in order, and the transport module 5 transports the iron cores 7 to the first winding module 3;

[0091] First winding: the rotating clamping mechanism 31 rotates to the initial position, the first clamping cylinder 3107 clamps and fixes the iron core 7 to be wound, and then the rotating clamping mechanism 31 rotates to the working position, the first wire supply module 4 outputs the copper wire, and the copper wire passes through the iron core 7 from top to bottom. When the length of the copper wire reaches the set length, the output of the copper wire stops;

[0092] The wire pulling mechanism 32 first pulls the copper wire under the iron core 7 to one side of the iron core 7, and drives the pulled copper wire to the top of the iron core 7. The wire hooking mechanism 33 extends from bottom to top, hooks the copper wire above the iron core 7, and pulls it downward, so that the copper wire is wound around the iron core 7. This is a winding operation.

[0093] Repeat the actions of the wire pulling mechanism 32 and the wire hooking mechanism 33. During this process, each time a winding operation is performed, the rotating clamping mechanism 31 drives the iron core 7 to rotate an angle. After repeating the winding operation multiple times, the copper wire is densely wound on the iron core 7.

[0094] Intermediate transportation: After the copper wire is wound on the iron core 7, the rotating clamping mechanism 31 rotates to the clamping position, and the transport module 5 transports the iron core 7 to the second winding module 3;

[0095] Second winding: the rotating clamping mechanism 31 rotates to the initial position, the first clamping cylinder 3107 clamps and fixes the iron core 7 to be wound, and then the rotating clamping mechanism 31 rotates to the working position, the second wire supply module 4 outputs the copper wire, and the copper wire passes through the iron core 7 from top to bottom. The output of the copper wire stops when the length of the copper wire reaches the set length;

[0096] The wire pulling mechanism 32 first pulls the copper wire under the iron core 7 to one side of the iron core 7, and drives the pulled copper wire to the top of the iron core 7. The wire hooking mechanism 33 extends from bottom to top, hooks the copper wire above the iron core 7, and pulls it downward, so that the copper wire is wound around the iron core 7. This is a winding operation.

[0097] Repeat the actions of the wire pulling mechanism 32 and the wire hooking mechanism 33. During this process, each time a winding operation is performed, the rotating clamping mechanism 31 drives the iron core 7 to rotate an angle. After repeating the winding operation multiple times, the copper wire is densely wound on the iron core 7.

[0098] Unloading: After the copper wire is wound around the iron core 7, the rotating clamping mechanism 31 rotates to the initial position, and the transport module 5 transports the iron core 7 for unloading;

[0099] In the first winding and the second winding, the core 7 maintains its original horizontal state or flips 180° according to the winding requirements.

[0100] Among them, when the iron core 7 only needs to be wound continuously once, only the winding operation of the first winding or the second winding is performed, and the winding module 3 that does not need to perform the winding operation serves as a transition station to clamp the iron core 7 or the product;

[0101] When the core 7 needs to be wound twice, both the first winding and the second winding need to be performed, and during the second winding, the core 7 is kept horizontal or flipped 180° according to the needs before the winding operation is performed.

[0102] It should be noted that one-time continuous winding refers to the operation of continuously winding a copper wire on the iron core 7 to form a common inductor coil. Two-time winding refers to the operation of winding a copper wire twice on the iron core 7 or winding two copper wires twice on the iron core 7, such as an inductor coil using a cross winding method (also known as clock winding method or butterfly winding method). It is easy to understand that the present invention is preferentially applicable to inductor coil products that require two-time winding.

[0103] It should be noted that, similar to the existing winding operation, in the winding process of the first winding module 3 and the winding process of the second winding module 3, after the wire supply module 4 stops conveying the copper wire, the copper wire is not cut off first, which is equivalent to the wire supply module 4 fixing the top of the copper wire, and the wire hooking mechanism 33 and the wire pulling mechanism 32 are for winding the remaining copper wire. After the copper wire near the bottom is wound, the wire supply module 4 cuts off the copper wire, and the wire hooking mechanism 33 and the wire pulling mechanism 32 wind the copper wire near the top. The above process is a conventional operation in this field, and the present invention will not repeat it.

[0104] In the present invention, the wire supply module 4 can be a common wire supply device in the field, as long as it can realize the wire supply operation required by the winding machine. Preferably, the present invention proposes a feasible wire supply module 4, as shown in the figure, the wire supply module 4 includes a wire supply base plate 41, a connecting seat 42, a wire supply rotating motor 43 and a wire supply assembly 44, the wire supply assembly 44 is arranged on the wire supply base plate 41, the bottom surface of the wire supply base is rotatably connected to the connecting seat 42 through a connecting rod 45, the connecting seat 42 is fixedly arranged on the frame 1, the wire supply rotating motor 43 is arranged below the frame 1, and the transmission shaft passes through the connecting seat 42 and is fixedly connected to the connecting rod 45 to control the rotation of the wire supply assembly 44.

[0105] The wire supply assembly 44 includes a wire feed guide wheel 4401, a wire feed motor 4402, a wire feed wheel 4403, a clamping cylinder 4404, a rotating frame 4407, a clamping wheel 4408, a cutter 4405 and a wire feed tube 4406. As shown in the figure, the wire feed guide wheel 4401 is arranged at the rear of the wire supply substrate 41, the wire feed wheel 4403 is horizontally and rotatably arranged above the wire supply substrate 41, the wire feed motor 4402 is arranged below the wire supply substrate 41, and the transmission shaft of the wire feed motor 4402 is connected to the wire feed wheel 4403 in a transmission manner, and the rotating frame 4407 is arranged on the wire supply substrate 41, located on one side of the wire feed wheel 4403, one side of the rotating frame 4407 is rotatably connected to the wire supply substrate 41, and the other side of the rotating frame 4407 is kept automatically. According to the state, the clamping wheel 4408 is horizontally and rotatably arranged in the rotating frame 4407, and the clamping wheel 4408 is close to the wire feeding wheel 4403, the copper wire is between the clamping wheel 4408 and the wire feeding wheel 4403, the clamping cylinder 4404 is arranged on the side of the rotating frame 4407 away from the wire feeding wheel 4403, the piston rod of the clamping cylinder 4404 is close to the other side of the rotating part that is not connected to the wire supply substrate 41, so as to drive the rotating frame 4407 to move toward the wire feeding wheel 4403 to clamp the copper wire, the wire feeding tube 4406 is arranged in front of the wire feeding wheel 4403, and the front end of the wire feeding tube 4406 is bent downward toward the iron core 7, and the cutter 4405 is between the wire feeding tube 4406 and the wire feeding wheel 4403 to cut the copper wire.

[0106] The working principle of the wire supply module 4 is: first, the copper wire is passed along the guide wheel through the clamping wheel 4408 and the wire feeding wheel 4403, and enters the wire feeding tube 4406. When the copper wire needs to be transported, the piston rod of the clamping cylinder 4404 extends, pushing the rotating frame 4407 to move in the direction of the wire feeding wheel 4403, so that the clamping wheel 4408 applies pressure in the direction of the wire feeding wheel 4403, and the copper wire is tightly clamped between the clamping wheel 4408 and the wire feeding wheel 4403. Then, the wire feeding motor 4402 drives the wire feeding wheel 4403 to rotate, and the copper wire is transported forward by friction. The length of the transported copper wire can be obtained according to the circumference of the circular cross section of the wire feeding wheel 4403 and the number of rotations.

[0107] Before conveying the copper wire, the front end of the wire feeding tube 4406 is aligned with the middle of the iron core 7, and the copper wire passes through the middle of the iron core 7. After the length of the conveyed copper wire reaches the set value, the wire feeding wheel 4403 stops rotating, and the wire feeding wheel 4403 and the clamping wheel 4408 still keep the copper wire clamped. Then the wire supply rotating motor 43 drives the wire supply assembly 44 to deflect an angle as a whole, so that the front end of the wire feeding tube 4406 is staggered from the iron core 7, which is convenient for the subsequent winding operation. When it is necessary to cut the copper wire, the cutter 4405 is started to cut the copper wire, and the copper wire in the front is continued to be wound and used, and the copper wire between the clamping wheel 4408 and the wire feeding wheel 4403 at the rear remains in a compressed state, waiting for the next wire feeding.

[0108] It is easy to understand that the wire feeding motor 4402 is provided with a feasible sensor such as an encoder to detect the number of revolutions of the wire feeding wheel 4403 .

[0109] The structure of the cutter 4405 is various. In the present invention, the cutter 4405 includes a baffle, a cutter and a cutter cylinder, the baffle and the cylinder body of the cutter cylinder are fixedly arranged on the wire feeding substrate, the cutter is arranged on the piston rod of the cutter cylinder, the cutter faces the baffle, and the copper wire is between the cutter and the baffle.

[0110] In the present invention, the transport module 5 can be a device commonly used in the art for transporting the iron core 7 or semi-finished products or finished products related thereto, as long as the device can realize the transport operation required by the winding machine.

[0111] In order to simplify the structure of the transport module 5, in the present invention, the loading module 2 and the two winding modules 3 are distributed along the same straight line, that is, the movement paths of the iron core 7, the semi-finished product or the finished product are in the same straight line, and the distance between the loading position of the loading module 2 and the position where the first winding module 3 clamps the iron core 7 and the distance between the position where the first winding module 3 clamps the iron core 7 and the position where the second winding module 3 clamps the iron core 7 are equal. The transport module 5 includes a transport bracket 51, a screw mechanism 52, a transport motor, a connecting plate 53, a lifting cylinder 55, a lifting guide rail 56, a fixing plate 54, a lifting plate 57 and a plurality of clamping components 58, the transport bracket 51 is arranged on the frame 1, the screw mechanism 52 is horizontally placed on the transport bracket 51, the transport motor is connected to the screw mechanism 52, which is not shown in the drawings, the connecting plate 53 is connected to the drive block of the screw mechanism 52, the fixing plate 54 is vertically arranged on one side of the connecting plate 53, and the lifting cylinder 55 is fixedly arranged On the fixed plate 54, the lifting plate 57 is located on the outer side of the fixed plate 54, the piston rod of the lifting cylinder 55 is connected to the lifting plate 57, the lifting guide rail 56 is fixedly arranged on the side of the fixed plate 54, and the lifting plate 57 is slidably connected to the lifting guide rail 56 on the side facing the fixed plate 54, and a plurality of clamping assemblies 58 are arranged on the side of the lifting plate 57 away from the fixed plate 54, and the plurality of clamping assemblies 58 are located above the loading module 2 and the two winding modules 3, and the distance between two adjacent clamping assemblies 58 is the same.

[0112] It is easy to understand that the transport module 5 controls the lifting and horizontal movement of the clamping assembly 58 , thereby realizing the transportation of the iron core 7 between the loading module 2 and the two winding modules 3 .

[0113] The clamping assembly 58 only descends to the top of the loading module 2 and the winding module 3 when it is needed to clamp the iron core 7 or the product. The clamping assembly 58 is in an ascending state and away from the loading module 2 and the winding module 3 below during the rest of the time.

[0114] Furthermore, the clamping assembly 58 is divided into a finished product clamping assembly 58 and a semi-finished product clamping assembly 58. The number of the semi-finished product clamping assembly 58 is one, which is used to transport the semi-finished product of the first winding module 3 to the second winding module 3. The remaining clamping assemblies 58 are finished product clamping assemblies 58. The number of the finished product clamping assemblies 58 is greater than or equal to three.

[0115] The finished product clamping assembly 58 includes a first transport clamping cylinder 5801 and two outer clamping jaws 5802, which are connected to the first transport clamping cylinder 5801 to clamp the outer side of the iron core 7 or the finished product; the semi-finished product clamping assembly 58 includes a second transport clamping cylinder 5803, an outer clamping jaw 5802 and an inner clamping jaw 5804, which are respectively connected to the second transport clamping cylinder 5803, the outer clamping jaw 5802 is in contact with the outer side of the semi-finished product where the copper wire is not wound, and the inner clamping jaw 5804 is in contact with the inner side of the semi-finished product where the copper wire is not wound.

[0116] The clamping principle of the semi-finished product clamping assembly 58 is the same as that of the finished product clamping assembly 58, that is, the two positions of the clamping contacting the iron core 7 or the semi-finished product or the finished product should be of the same material. For example, when the first winding module 3 produces a semi-finished product, if the finished product clamping assembly 58 is used to clamp the semi-finished product, one side of the clamping jaw will contact the copper wire winding surface, and the other side of the clamping jaw will contact the iron core 7. The friction force on both sides is different (the friction force in contact with the copper wire is smaller), and the clamping force needs to be increased, causing the copper wire winding surface to be deformed under pressure, affecting product quality.

[0117] In the present invention, the feeding module 2 is a conventional vibration plate feeding device 21, which is the same as the existing conventional winding machine feeding device, and the present invention will not repeat it.

[0118] In the present invention, the winding machine further comprises an upper bottom plate module 6. The bottom plate refers to an object inserted into the inductor coil, which is generally inserted manually. The present invention realizes automatic loading of the bottom plate through the upper bottom plate module 6. As shown in the figure, the upper bottom plate module 6 is a device extended and installed on the rear side of the frame 1.

[0119] The upper base plate module 6 includes a mounting base plate 61 for base plate feeding and a base plate vibration disk 62, a rotating cylinder 63, a base plate clamping cylinder 64 and a finished product collection box arranged on the mounting base plate 61. The rotating cylinder 63 is located behind the second winding module 3, the base plate vibration disk 62 is located behind the rotating cylinder 63, and the finished product collection box is located in front of the rotating cylinder 63 (not shown in the accompanying drawings). The base plate clamping cylinder 64 is connected to the rotating cylinder 63, and there is a clamping assembly 58 directly above the base plate clamping cylinder 64.

[0120] It is easy to understand that the position of the bottom plate clamping cylinder 64 is actually the position of the conventional product unloading. The present invention realizes the automatic loading of the bottom plate at the unloading position. The working principle of the upper bottom plate module 6 is: the rotating cylinder 63 controls the bottom plate clamping cylinder 64 to rotate to a state aligned with the discharge port of the bottom plate vibration plate 62, first clamping a bottom plate, and then the bottom plate clamping cylinder 64 rotates to a vertical state, with the bottom plate facing upward. When the clamping assembly 58 descends, the clamping assembly 58 located directly above the bottom plate clamping cylinder 64 drives the finished product to descend until the bottom plate is inserted into the finished product, and then the clamping assembly 58 releases the finished product. Due to the connection relationship between the bottom plate and the finished product, the finished product is stably at the top of the bottom plate clamping cylinder 64. Finally, the bottom plate clamping cylinder 64 rotates to make the finished product above the finished product collection box. After the bottom plate clamping cylinder 64 is released, the finished product automatically falls into the finished product collection box.

[0121] In the present invention, the winding machine further comprises a control module, which is an electrical control device connected to the other modules to realize the orderly operation of the modules. The control module of the present invention is an existing conventional electrical control device, which will not be described in detail in the present invention.

[0122] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
