Description

TECHNICAL FIELD

[0001] The application relates to the technical field of magnetic core processing, in particular to a magnetic core winding machine. BACKGROUND

[0002] A coil generally refers to a ring-shaped wire winding, which plays an important role as a core component of a motor, and is generally composed of a magnetic core and copper wire wound on the magnetic core. The magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures, and a common structural form of the magnetic core is a loop shape. At present, the operation mode of winding copper wire on the loop-shaped magnetic core is as follows: first, the loop-shaped magnetic core is positioned on a simple jig, then a winding worker holds the copper wire with one hand, passes the copper wire through the through hole in the middle of the magnetic core from the top to the bottom, holds the copper wire passing through the magnetic core with the other hand from the bottom, then winds the copper wire around the magnetic core, and then sends the copper wire back to the top of the magnetic core. In this way, the winding and arranging are completed through the reciprocating action.

[0003] However, the traditional winding mode basically depends on manual operation, and inevitably has problems of high labor intensity, low operation efficiency, and poor winding quality reliability. SUMMARY

[0004] Therefore, it is necessary to provide a magnetic core winding machine in view of the problems of high labor intensity, low operation efficiency and unstable winding quality of manual winding.

[0005] The application provides a magnetic core winding machine, which comprises:

[0006] A winding execution mechanism, the winding execution mechanism comprises a displacement module, a rotating module and a wire clamping module, the displacement module is used for outputting multi-axis linear power, the rotating module is arranged on the displacement module and is used for outputting rotating power, and the wire clamping module is matched with the rotating module and is used for clamping or releasing the copper wire;

[0007] A wire guiding mechanism, the wire guiding mechanism is arranged on the opposite side of the winding execution mechanism, and is used for guiding the copper wire to the winding station and moving the copper wire once along the winding arrangement direction after the copper wire completes winding the loop-shaped magnetic core once;

[0008] A clamp mechanism, the clamp mechanism is arranged on the winding station and is used for clamping and positioning the loop-shaped magnetic core; and

[0009] A wire pulling mechanism, the wire pulling mechanism is arranged below or on the side of the loop-shaped magnetic core, and is used for pulling the copper wire to pass through the through hole of the loop-shaped magnetic core.

[0010] The magnetic core winding machine described above is specifically applied to the processing of coiled magnetic cores for automatic, manual winding of copper wire. Specifically, during processing, the coiled magnetic core is first clamped and positioned in the fixture mechanism, with the through-hole of the coiled magnetic core arranged vertically. Next, the wire guiding mechanism moves the copper wire to the winding station, positioning it above the through-hole of the coiled magnetic core. At this point, the shifting module of the winding execution mechanism moves, causing the clamping module to approach and clamp the copper wire. Then, the shifting module moves downwards again, allowing the clamping module to lower the end of the copper wire, allowing it to pass through the through-hole and extend below the coiled magnetic core. Immediately afterwards, the wire pulling mechanism clamps the end of the copper wire that has passed through the through-hole and pulls it further down a certain distance. During this process, the clamping module releases the copper wire and moves it to the lower side of the loop core under the movement of the shifting module. At this time, the pulling mechanism releases the copper wire while the clamping module clamps the copper wire after it has been passed through the hole. Then, the rotating module starts and drives the clamping module to rotate around the outer circumference of the loop core by a preset angle (such as 180°), which pulls the copper wire back to the top of the loop core and completes one winding of the copper wire onto the loop core. Afterward, the wire guiding mechanism moves step by step along the winding direction, so that the copper wire avoids the already wound part of the loop core. Then, the above process is repeated to complete the next winding of the copper wire onto the loop core and the winding arrangement, and so on until the winding process of the core is completed. Compared with the manual winding operation method of the prior art, this solution can realize the automatic winding and installation of copper wire onto the loop core. The whole process does not require human intervention, has a high degree of automation, helps to reduce the labor intensity of workers, improves the efficiency of winding operation, and the high precision of the cooperation of each functional mechanism can ensure stable and reliable winding quality.

[0037] See Figure 1 This application presents a magnetic core winding machine 100 as an embodiment, which is used to automatically complete the task of winding copper wire onto a magnetic core, replacing manual labor.

[0038] Specifically, in this application, the magnetic core is a spiral magnetic core 200. Copper wires need to be wound on the two opposite rods of the spiral magnetic core 200, and the copper wires are arranged side by side on the rods in the same direction. This arrangement direction is the winding and arrangement direction.

[0039] As is easily understood, the copper wire is wound onto the rod in a continuous spiral winding method, which is more suitable for automated continuous copper wire winding processing and ensures full wire coverage.

[0040] For example, the magnetic core winding machine includes a winding execution mechanism 10, a wire guiding mechanism 20, a clamping mechanism 30, and a wire pulling mechanism 40.

[0041] The winding execution mechanism 10 comprises a displacement module 11, a rotating module 12 and a wire clamping module 13, the displacement module 11 is used for outputting multi-axis linear power, the rotating module 12 is arranged on the displacement module 11 and is used for outputting rotating power, and the wire clamping module 13 is matched with the rotating module 12 and is used for clamping or releasing the copper wire.

[0042] The wire guiding mechanism 20 is arranged on the opposite side of the winding execution mechanism 10, and the wire guiding mechanism 20 and the winding execution mechanism 10 have a spacing, and all or part of the space of the spacing forms a working place of the copper wire winding on the U-shaped magnetic core 200, i.e. a winding station. The wire guiding mechanism 20 is used for guiding the copper wire to the winding station and moving the copper wire once along the winding arrangement direction after each winding of the U-shaped magnetic core 200.

[0043] The clamp mechanism 30 is arranged at the winding station and is used for clamping and positioning the U-shaped magnetic core 200, and the wire pulling mechanism 40 is arranged below or on the side of the U-shaped magnetic core 200 and is used for pulling the copper wire through the through hole of the U-shaped magnetic core 200.

[0044] In summary, the technical scheme of the embodiment has the following beneficial effects: the magnetic core winding machine 100 of the above scheme is specifically applied to the processing occasion of automatically winding the copper wire on the U-shaped magnetic core 200 without human intervention. Specifically, during processing, the U-shaped magnetic core 200 is first clamped and positioned in the clamp mechanism 30, and the through hole of the U-shaped magnetic core 200 is arranged in the vertical direction. Then the wire guiding mechanism 20 moves the copper wire to the winding station above the through hole of the U-shaped magnetic core 200. At this time, the displacement module 11 of the winding execution mechanism 10 moves, driving the wire clamping module 13 to approach and clamp the copper wire. Then the displacement module 11 moves downward again, so that the wire clamping module 13 can drive the wire head of the copper wire to descend and pass through the through hole and extend below the U-shaped magnetic core 200. Then the wire pulling mechanism 40 clamps the wire head of the copper wire passing through the lower end of the through hole and further moves a distance downward. In this process, the wire clamping module 13 has released the copper wire and moved to the side below the U-shaped magnetic core 200 under the movement of the displacement module 11. At this time, the wire pulling mechanism 40 releases the copper wire, and the wire clamping module 13 clamps the copper wire passing through the through hole again. Then the rotating module 12 starts to drive the wire clamping module 13 to rotate around the outer periphery of the U-shaped magnetic core 200 by a preset angle (such as 180°), so as to pull the copper wire to the upper side of the U-shaped magnetic core 200 again and complete the winding of the copper wire on the U-shaped magnetic core 200 once. Then the wire guiding mechanism 20 moves step by step along the winding arrangement direction, so that the copper wire avoids the part of the U-shaped magnetic core 200 that has been wound. Then the above process is repeated again to complete the winding of the copper wire on the U-shaped magnetic core 200 and the winding arrangement of the copper wire. The above process is repeated until the winding processing of the magnetic core is completed.

[0045] Compared with the manual winding operation mode of the prior art, the scheme can realize the processing content of automatically winding the copper wire to the U-shaped magnetic core 200, the whole process does not need human intervention, the automation degree is high, which helps to reduce the labor intensity of workers, improve the winding operation efficiency, and the cooperation precision of each functional mechanism is high, which can ensure the stable and reliable winding quality.

[0046] It can be understood that, analogously to the manual winding operation mode of the magnetic core, the winding execution mechanism 10 in the scheme simulates the action of one hand of the worker, that is, completes the threading and copper wire winding; the guide and line mechanism 20 simulates the action of the other hand of the worker, that is, takes the wire and aligns the copper wire with the through hole of the U-shaped magnetic core 200. Thus, the worker can be replaced to automatically complete the magnetic core winding processing.

[0047] Please continue to refer to Figure 1 In some embodiments, the magnetic core winding machine 100 further comprises a base plate 50, the displacement module 11 comprises an X-axis driving unit 111, a Y-axis driving unit 112 and a Z-axis driving unit 113, the X-axis driving unit 111 and the guide and line mechanism 20 are respectively arranged at opposite ends of the base plate 50, the Y-axis driving unit 112 is connected with the X-axis driving unit 111, the Z-axis driving unit 113 is connected with the Y-axis driving unit 112, and the rotation module 12 is connected with the Z-axis driving unit 113.

[0048] The X-axis driving unit 111 is used to output reciprocating linear power along the X-axis direction, the Y-axis driving unit 112 is used to output reciprocating linear power along the Y-axis direction, and the Z-axis driving unit 113 is used to output reciprocating linear power along the Z-axis direction. Under the cooperation of the three, the rotation module 12 and the line clamping module 13 can be accurately guided to the winding station, and the line clamping module 13 can drive the copper wire to perform a series of actions such as perforating and winding.

[0049] Specifically, the Y-axis driving unit 112 provides the clamping module 13 with a lifting movement force in the Y-axis direction, so that the clamping module 13 can pass the wire end of the copper wire into the through hole from the upper hole of the through hole and extend to the lower hole. After the wire pulling mechanism 40 pulls the wire end of the copper wire downward by a certain length, the clamping module 13 moves to the lower side of the magnetic core under the movement of the Y-axis driving unit 112 and clamps the wire end of the copper wire released by the wire pulling mechanism 40 again. Then the rotating module 12 starts and drives the clamping module 13 to rotate 180° from the lower side to the upper side of the magnetic core, so that the copper wire completes a winding of the rod of the magnetic core and is reset to the upper hole of the through hole at the same time. Then the clamping module 13 moves downward again under the driving of the Y-axis driving unit 112 to pass the copper wire through the through hole for the second time. Then the clamping module 13 releases the copper wire, and the rotating module 12 drives the clamping module 13 to rotate and reset to the lower side of the magnetic core. After the wire pulling mechanism 40 pulls the copper wire downward by a certain distance, the clamping module 13 clamps the copper wire again and completes the second winding of the rod of the magnetic core by means of the rotation of the rotating module 12. The above process is repeated until the winding of the copper wire on one side of the rod is completed. Then the magnetic core on the other side of the rod can be wound.

[0050] In the present application, the X-axis driving unit 111, the Y-axis driving unit 112 and the Z-axis driving unit 113 can have various forms of implementation. For example, in some optional embodiments, the X-axis driving unit 111, the Y-axis driving unit 112 and the Z-axis driving unit 113 each include a servo motor, a screw assembly and a guide rail. The servo motor is drivingly connected with the screw assembly, and the guide rail is arranged on one side of the screw assembly and has a moving direction consistent with the reciprocating movement direction of the screw assembly.

[0051] The screw assembly can convert the rotary power output by the servo motor into linear power, so as to drive the rotating module 12 and the clamping module 13 to move linearly along the X-axis, Y-axis and Z-axis directions respectively or simultaneously. The power output is stable, and the movement precision is high, which helps to ensure that the copper wire is wound on the small-size shaped magnetic core 200 safely and efficiently, avoids collision damage to the shaped magnetic core 200 and causes the copper wire to be pulled and broken, and affects the quality of the magnetic core winding process and normal processing.

[0052] Of course, in other embodiments, the X-axis driving unit 111, the Y-axis driving unit 112 and the Z-axis driving unit 113 can also adopt structures such as a cylinder and a slider rail, a motor and a scissor mechanism, which are also within the protection scope of the present application.

[0053] Please continue to refer to Figure 3In some embodiments, the rotating module 12 comprises a rotating base 121, a rotating actuating assembly, and a rotating shaft 122. The rotating base 121 is configured with the Z-axis driving unit 113. The rotating actuating assembly is arranged on the rotating base 121 and is used to output a rotating driving force. The rotating shaft 122 is rotatably arranged on the rotating base 121. One end of the rotating shaft 122 is connected with the rotating actuating assembly, and the other end of the rotating shaft 122 is connected with the wire clamping module 13. The wire clamping module 13 is driven to rotate around the outer periphery of the magnetic core to wind the copper wire on the magnetic core. Therefore, the rotating module 12 has simple structure and working principle. The rotating shaft 122 in the rotating state further drives the wire clamping module 13 to rotate around the outer periphery of the magnetic core, which can simulate the winding of the copper wire on the magnetic core by human hand, has high winding efficiency, and has good winding quality.

[0054] Specifically, in the above embodiment, the rotating actuating assembly comprises a stepping motor 123, a first transmission wheel 124, a transmission member 125, and a second transmission wheel 126. The stepping motor 123 is arranged on the rotating base 121 and is connected with the first transmission wheel 124. The second transmission wheel 126 is connected with the rotating shaft 122. The transmission member 125 is sleeved on the outside of the first transmission wheel 124 and the second transmission wheel 126.

[0055] In operation, the rotating driving force output by the stepping motor 123 can be stably and efficiently transmitted to the rotating shaft 122 through the first transmission wheel 124, the transmission member 125, and the second transmission wheel 126, so as to ensure the rotation angle and stroke accuracy of the wire clamping module 13 and to make the winding quality of the copper wire good.

[0056] Please continue to refer to Figure 3 Further, the rotating module 12 further comprises an inductor 127 and an inductive sheet 128. The inductor 127 is arranged on the rotating base 121 and is electrically connected with the stepping motor 123. The inductive sheet 128 is connected with the second transmission wheel 126. The inductive sheet 128 can be inducted with the inductor 127. When the second transmission wheel 126 rotates by 180°, the inductive sheet 128 intersects with the inductor 127 once to generate a trigger. The inductor 127 generates a trigger signal and outputs an instruction to the stepping motor 123 to stop in time, so as to ensure that the wire clamping module 13 can be accurately stopped above the through hole when rotating from below the magnetic core to above the magnetic core. The wire clamping module 13 can be directly lowered under the driving of the Y-axis driving unit 112 to complete the next copper wire perforation operation, which saves the time and process steps of the alignment of the copper wire and the through hole, and improves the winding efficiency of the magnetic core.

[0057] Please continue to refer to Figure 2In some embodiments, the wire clamping module 13 comprises a wire clamping cylinder 131, a first wire clamping jaw 132 connected with a first driving arm of the wire clamping cylinder 131, and a second wire clamping jaw 133 connected with a second driving arm of the wire clamping cylinder 131, the second wire clamping jaw 133 being capable of closing or separating from the first wire clamping jaw 132.

[0058] In operation, the wire clamping cylinder 131 can simultaneously drive the first driving arm and the second driving arm to move towards each other or move away from each other, thereby enabling the first wire clamping jaw 132 and the second wire clamping jaw 133 to close to clamp the copper wire or separate to release the copper wire.

[0059] In some other embodiments, the clamp mechanism 30 comprises a clamp cylinder 31, a first clamp arm 32 connected with a first driving arm of the clamp cylinder 31, and a second clamp arm 33 connected with a second driving arm of the clamp cylinder 31, the second clamp arm 33 being capable of closing or separating from the first clamp arm 32.

[0060] In operation, the clamp cylinder 31 can simultaneously drive the first driving arm and the second driving arm to move towards each other or move away from each other, thereby enabling the first clamp arm 32 and the second clamp arm 33 to close to clamp the meander-shaped magnetic core 200 or separate to release the meander-shaped magnetic core 200.

[0061] Please continue to refer to Figure 1 and Figure 6 In the present application, the wire guiding and arranging mechanism 20 has the functions of supplying copper wire, guiding copper wire feeding, and arranging copper wire during winding. In some embodiments, the wire guiding and arranging mechanism 20 comprises a Y-axis moving assembly 21 and a wire guiding block 22, the wire guiding block 22 being connected with the Y-axis moving assembly 21, the wire guiding block 22 being provided with a wire guiding groove 221 penetrating through both ends in the vertical direction, the wire guiding groove 221 being used for threading the copper wire, and the Y-axis moving assembly 21 being used for outputting a step driving force in the Y-axis direction, so that the distance of each movement of the wire guiding block 22 is equal to the wire diameter of the copper wire.

[0062] It is easy to understand that the guide wire mechanism 20 is also provided with a wire feeder such as a wire drum. The copper wire is wound on the outside of the wire drum. When needed, the copper wire is wound and pulled out from the copper wire drum. The wire guide block 22 guides and limits the copper wire. When the Y-axis moving assembly 21 moves the wire guide block 22 close to the magnetic core 200, the wire guide block 22 can position the copper wire above the upper opening of the through hole of the magnetic core 200. After the copper wire is wound on the magnetic core 200 once, the Y-axis moving assembly 21 moves away from the magnetic core 200 once. The distance of the movement is equal to the diameter of the copper wire, so that the copper wire that has not been wound can be offset from the copper wire that has been wound on the magnetic core 200. The copper wire can be arranged in the next winding according to the winding arrangement direction, so as to improve the full winding rate of the magnetic core 200 and improve the performance of the coil after winding.

[0063] Please continue to refer to Figure 5 In addition, on the basis of any of the above embodiments, the puller mechanism 40 includes a lifting cylinder 41, a puller cylinder 42, a first puller clamp jaw 43, and a second puller clamp jaw 44. The lifting cylinder 41 is arranged on the clamp mechanism 30 and is used to output a lifting movement force in the Z-axis direction. The puller cylinder 42 is connected with the piston rod of the lifting cylinder 41 and is arranged horizontally along the X-axis direction. The first puller clamp jaw 43 is connected with a first driving arm of the puller cylinder 42. The second puller clamp jaw 44 is connected with a second driving arm of the puller cylinder 42. The second puller clamp jaw 44 can be closed or separated from the first puller clamp jaw 43.

[0064] The lifting cylinder 41 outputs a lifting force, so that the first puller clamp jaw 43 and the second puller clamp jaw can clamp the copper wire and pull the copper wire downward to move away from the magnetic core 200, so as to facilitate the subsequent clamping and turning winding operation of the wire clamping module 13 and the upward reset of the first puller clamp jaw 43 and the second puller clamp jaw after releasing the copper wire for secondary work. The puller cylinder 42 is used to drive the first puller clamp jaw 43 and the second puller clamp jaw 44 to be closed or separated, so as to clamp or release the copper wire. The structure and working principle of the puller mechanism 40 are simple and easy to implement.
