Technical Field

[0001] This invention relates to the field of flat copper wire processing technology, and in particular to an automatic flat copper wire winding and stacking device and method. Background Technology

[0002] Flat copper wire refers to copper conductors with a flat cross-section. Because they can increase conductor fill rate and improve energy conversion efficiency within a limited space, they are widely used in electronic components such as motors and inductors. In practical applications, flat copper wires are usually wound to achieve multi-layer stacking, facilitating further increases in conductor usage.

[0003] However, existing winding methods generally suffer from low forming accuracy and easy skewing of coil structures during the layer-by-layer stacking of flat wires. Therefore, how to improve the stacking accuracy during the winding process of flat copper wires in a simple and reliable way, and effectively suppress the skewing problem of multi-layer structures during the winding process, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] To help improve the stacking accuracy during the winding of flat copper wire and effectively suppress the skewing problem of multi-layer coil structures during the winding process, this invention provides an automatic winding and stacking device and method for flat copper wire.

[0005] In a first aspect, the present invention provides an automatic winding and stacking device for flat copper wires, which adopts the following technical solution: An automatic flat copper wire winding and stacking device includes: A winding and stacking mechanism includes a winding table, a positioning body, a movable slide body, a movable slide drive component, and a lifting component. The positioning body is disposed on the winding table, and the movable slide body is slidably disposed on the winding table. The movable slide body moves along the circumferential direction of the positioning body. The movable slide body and the positioning body are located on opposite sides of the flat copper wire. The movable slide body is used to abut against the flat copper wire bending along the positioning body. The movable slide drive component is disposed on the winding table and is used to drive the movable slide body to reciprocate. The lifting component is used to lift the wound and stacked annular coil upward. A limiting mechanism is provided, comprising a limiting rod and a limiting drive member. The limiting rod is used to extend into the wound and stacked annular coils to limit the winding and stacked annular coils, and the limiting drive member is used to drive the limiting rod to move toward or away from the annular coils.

[0006] Preferably, the limiting rod is located above the positioning body and aligned with the center of the positioning body, and the limiting rod moves in the vertical direction.

[0007] Preferably, the winding and stacking mechanism further includes a feeding rod, which has a feeding channel for passing through flat copper wires. The flat copper strip output from the feeding channel enters between the moving slide body and the positioning body. The lifting component includes a first guide slope and a second guide slope. The first guide slope is disposed on the feeding rod, and the second guide slope is disposed on the side of the moving slide body near the positioning body. The first guide slope is inclined downward in a direction away from the feeding channel, and the second guide slope is inclined downward in a direction close to the positioning body. The annular coil bent and fed out between the moving slide body and the positioning body is located above the first guide slope and the second guide slope.

[0008] Preferably, the sliding body includes an abutment portion and a limiting portion. The abutment portion is slidably disposed on the winding table, and the limiting portion is integrally disposed on the abutment portion and extends out of the abutment portion. A winding channel for passing through a flat copper wire is provided on the side of the abutment portion near the positioning body. The winding channel is located below the limiting portion, and the upper surface of the flat copper wire located in the winding channel abuts against the lower surface of the limiting portion. The second guide slope is located on the side of the limiting portion near the positioning body.

[0009] Preferably, the limiting part slides against the upper surface of the positioning body.

[0010] Preferably, the automatic winding and stacking device further includes a first support frame and a second support frame. The first support frame is used to support the annular coil being wound. The first support frame has a support plane that is flush with the bottom wall of the winding channel. When the winding channel is aligned with the feeding channel, the support plane is located on the side of the moving slide away from the feeding rod. The second support frame has a guide output plane that is located on the side of the support plane away from the moving slide and is inclined downward in a direction away from the support plane.

[0011] Preferably, the automatic winding and stacking device further includes a mounting plate, a first mounting base, and a second mounting base. The mounting plate is arranged vertically, and a through hole for flat copper wires to pass through is opened in the center of the mounting plate. The feeding rod is arranged on the mounting plate, and the feeding channel is aligned with the through hole. Both the first mounting base and the second mounting base are arranged on the mounting plate. The winding table is arranged on the first mounting base, and the limiting drive is arranged on the second mounting base. A sliding seat is slidably arranged on the second mounting base in the vertical direction, and a limiting rod is arranged on the sliding seat. The limiting drive is used to drive the sliding seat to move the limiting rod toward or away from the annular coil.

[0012] Preferably, the limiting rod is rotatably mounted on the sliding seat, the rotation direction of the limiting rod is perpendicular to the length direction of the feeding channel, and the sliding seat is provided with a rotating component for driving the limiting rod to rotate.

[0013] Preferably, the automatic winding and stacking device further includes a wire feeding mechanism, a pre-treatment mechanism, and a cutting mechanism. The wire feeding mechanism is used to unwind flat copper wire, and the pre-treatment mechanism is used to pre-treat the flat copper wire. The pre-treatment mechanism includes a pre-treatment frame, a conductive sponge, and a straightening component. The conductive sponge is disposed on the pre-treatment frame, and the flat copper wire unwound from the wire feeding mechanism slides through the conductive sponge. The straightening component is disposed on the pre-treatment frame and is used to straighten the conveyed flat copper wire. The cutting mechanism is used to cut the wound annular coil.

[0014] Secondly, the present invention provides an automatic winding and stacking method for flat copper wires, which adopts the following technical solution: An automatic winding and stacking method for flat copper wires, using the aforementioned automatic winding and stacking device for flat copper wires, includes the following steps: Step 1: The flat copper wire is unwound and fed out by the unwinding mechanism. The flat copper wire is cleaned and destaticated by the conductive sponge, and then straightened by the straightening component. Step 2: Next, the flat copper wire is conveyed between the moving slide and the positioning body, and the flat copper wire moves forward a first preset distance after passing through the moving slide; Step 3: While the flat copper wire continues to move forward, the sliding drive drives the sliding body to move circumferentially along the positioning body, so that the sliding body abuts against the flat copper wire and rotates 90 degrees along the positioning body to bend it. Then the sliding body returns to its original position, and the flat copper wire continues to move a second preset distance. Then, while the flat copper wire continues to move forward, the sliding drive drives the sliding body to move circumferentially along the positioning body again, so that the sliding body abuts against the flat copper wire and rotates 90 degrees along the positioning body to bend it. Then the flat copper wire continues to be conveyed forward a third preset distance. Step 4: Then repeat step 3 to make the flat copper wires stacked into a ring coil. The formed ring coil is gradually lifted by the lifting component. Step 5: As the number of stacked layers of the loop coil gradually increases, the limiting rod is located inside the wound and stacked loop coil to limit the loop coil; Step 6: After the loop coils are stacked to the preset number of layers, the limiting drive is used to drive the limiting rod away from the loop coils until it extends out of the loop coils. Then, the shearing mechanism cuts the wound loop coils to complete the winding of one product.

[0015] In summary, the present invention has the following beneficial technical effects: The flat copper wire, after being conveyed, enters between the moving slide body and the positioning body. Simultaneously, the moving slide body is driven by the moving slide drive to move circumferentially along the positioning body, causing it to bend the flat copper wire by rotating 90 degrees around the positioning body. The moving slide body then returns to its original position, and the flat copper wire continues to move. The moving slide body is again driven by the moving slide drive to move circumferentially along the positioning body, causing it to bend the flat copper wire by rotating 90 degrees around the positioning body. The flat copper wire continues to be conveyed forward, and the bending steps are repeated, gradually winding the flat copper wire into a loop coil. During the bending and winding process, the loop coil is gradually lifted upwards by the lifting component. As the number of stacked layers of the loop coil gradually increases, a limiting rod is located inside the loop coil to limit its position. This invention, through the cooperation of the moving slide body, the positioning body, and the lifting component, helps to ensure the stacking accuracy of the flat copper wire during winding. The limiting rod located inside the loop coil can effectively suppress the skewing problem of multi-layer coil structures during winding. Attached Figure Description

[0025] The following combination Figures 1-8 The present invention will be described in further detail below.

[0026] Example 1:

[0027] This invention discloses an automatic winding and stacking device for flat copper wires. (Refer to...) Figure 1 and Figure 2 The automatic flat copper wire winding and stacking device includes a wire feeding mechanism 17, a pre-treatment mechanism 18, a winding and stacking mechanism 1, a limiting mechanism 2, and a cutting mechanism 19. The wire feeding mechanism 17 is used to unwind and feed out the flat copper wire, the pre-treatment mechanism 18 is used to pre-treat the flat copper wire, the winding and stacking mechanism 1 is used to wind and stack the flat copper wire, the limiting mechanism 2 is used to limit the wound and stacked annular coil, and the cutting mechanism 19 is used to cut the wound annular coil. Specifically, the flat copper wire unwound and fed from the wire feeding mechanism 17 passes through the pre-treatment mechanism 18 and the winding and stacking mechanism 1 in sequence.

[0028] Reference Figure 1 and Figure 3To facilitate the installation of the winding and stacking mechanism 1, the limiting mechanism 2, and the shearing mechanism 19, the automatic winding and stacking device also includes a mounting plate 5, a first mounting base 6, a second mounting base 7, and a third mounting base 20. The mounting plate 5 is a circular plate fixed in the vertical direction, and a through hole (not shown in the figure) is opened in the center of the mounting plate 5 for flat copper wires to pass through. The pretreatment mechanism 18 and the winding and stacking mechanism 1 are located on opposite sides of the mounting plate 5. The flat copper wires passing through the pretreatment mechanism 18 reach the winding and stacking mechanism 1 through the through hole in the center of the mounting plate 5. The first mounting base 6, the second mounting base 7, and the third mounting base 20 are all set on the mounting plate 5. Specifically, the winding and stacking mechanism 1 is set on the first mounting base 6, the limiting mechanism 2 is set on the second mounting base 7, and the shearing mechanism 19 is set on the third mounting base 20 to achieve a compact structure.

[0029] Reference Figure 3 and Figure 4 To facilitate the winding and stacking of flat copper wires, the winding and stacking mechanism 1 includes a winding table 11, a positioning body 12, a movable slide body 13, a movable slide drive 14, and a lifting assembly 15. The winding table 11 is fixedly mounted on the first mounting base 6, and the positioning body 12 is fixedly mounted on the winding table 11. The positioning body 12 is cylindrical. The movable slide body 13 is slidably mounted on the winding table 11 and moves along the circumference of the positioning body 12. The flat copper wires conveyed from the pre-processing mechanism 18 enter between the movable slide body 13 and the positioning body 12, so that the movable slide body 13 and the positioning body 12 are located on opposite sides of the flat copper wires. The movable slide body 13 is used to abut against the flat copper wires bending along the positioning body 12. The movable slide drive 14 is mounted on the winding table 11 and is used to drive the movable slide body 13 to move. The lifting assembly 15 is used to lift the wound and stacked annular coils upward.

[0030] Reference Figure 3 and Figure 4 To facilitate the limiting of the wound and stacked coils, the limiting mechanism 2 includes a limiting rod 21 and a limiting drive member 22. The limiting rod 21 is used to extend into the wound and stacked annular coils to limit the annular coils. The limiting drive member 22 is disposed on the second mounting base 7 and is used to drive the limiting rod 21 to move toward or away from the annular coils.

[0031] During operation, the flat copper wire is unwound and fed out by the unwinding mechanism 17. Then, the flat copper wire undergoes pre-processing by the pre-processing mechanism 18. Next, the flat copper wire is conveyed through the through-hole in the center of the mounting plate 5 into the space between the moving slide body 13 and the positioning body 12. The flat copper wire then moves forward a first preset distance. While the flat copper wire continues to be conveyed, the moving slide drive 14 drives the moving slide body 13 to move circumferentially along the positioning body 12, causing the moving slide body 13 to abut against the flat copper wire and bend it by rotating 90 degrees along the positioning body 12. Then, the moving slide body 13 returns to its original position, and the flat copper wire continues to be conveyed forward a second preset distance. Then, while the flat copper wire continues to be conveyed, the moving slide drive 14 again drives the moving slide body 13 circumferentially along the positioning body 12. The sliding body 13 moves forward, causing the flat copper wire to bend by rotating 90 degrees along the positioning body 12. The flat copper wire continues to be conveyed forward a third preset distance, and the bending steps are repeated to gradually wind the flat copper wire into a loop coil. During the bending and winding process, the loop coil is lifted layer by layer by the lifting component 15. As the number of loop coil stacked increases, the limiting rod 21 extends into the wound and stacked loop coil. The limiting rod 21 can limit the wound and stacked loop coil. When the loop coil is stacked to the preset number of layers, the limiting drive 22 drives the limiting rod 21 to extend out of the loop coil. Then, the shearing mechanism 19 cuts the wound loop coil, completing the winding of one product. In this invention, the cooperation of the sliding body 13, the positioning body 12 and the lifting component 15 enables the flat copper wire to be wound in an orderly manner, which helps to ensure the stacking accuracy of the flat copper wire during the winding process. The insertion of the limiting rod 21 into the ring coil can effectively suppress the skewing problem of the multi-layer coil structure during the winding process to a certain extent.

[0032] Reference Figure 1 Specifically, for unwinding and feeding flat copper wire, the unwinding mechanism 17 includes an unwinding frame 171 and an unwinding machine 172. The unwinding machine 172 is mounted on the unwinding frame 171. During operation, the flat copper wire coil is mounted on the unwinding machine 172, which is used to unwind the flat copper wire.

[0033] Reference Figure 1 and Figure 2To facilitate pre-processing of flat copper wires, the pre-processing mechanism 18 includes a pre-processing frame 181, a conductive sponge 182, and a straightening assembly 183. The mounting plate 5 is fixedly connected to the pre-processing frame 181. The conductive sponge 182 is detachably fixed to the pre-processing frame 181 by bolts. The flat copper wire unwound from the unwinding mechanism 17 slides through the conductive sponge 182. The straightening assembly 183 is mounted on the pre-processing frame 181 and is used to straighten the conveyed flat copper wires. Specifically, the straightening assembly 183 includes a horizontal straightening group 1831 and a vertical straightening group 1832. The horizontal straightening group 1831 includes multiple first guide rollers arranged opposite each other along the width direction of the flat copper strip, with the first guide rollers on opposite sides being staggered. The vertical straightening group 1832 includes multiple second guide rollers arranged vertically opposite each other, with the second guide rollers on opposite sides being staggered. The flat copper strip fed from the wire feeding mechanism 17 passes sequentially through the conductive sponge 182, the first guide rollers, and the second guide rollers, and then enters the through hole on the mounting plate 5. The conductive sponge 182 is existing technology, and using the conductive sponge 182 helps to clean and remove static electricity from the flat copper wire; while the multiple first guide rollers and multiple second guide rollers help to ensure the flatness of the flat copper strip. Furthermore, to improve the conveying effect of the flat copper strip, an active component is provided on the pre-processing frame 181 to drive multiple second guide rollers to rotate synchronously. The active component can be driven by a motor, pulley, belt or motor, sprocket, chain. Specifically, the active component is existing technology and will not be described in detail here. By driving multiple second guide rollers to rotate through the active component, it is helpful to actively convey the flat copper strip towards the mounting plate 5.

[0034] Reference Figure 3 and Figure 5 To facilitate the winding and stacking of flat copper wires, the winding and stacking mechanism 1 also includes a feeding rod 16. The feeding rod 16 is fixed at the center of the mounting plate 5 near the winding table 11. The length direction of the feeding rod 16 is perpendicular to the plane of the mounting plate 5. A feeding channel 3 for the flat copper wires to pass through is provided inside the feeding rod 16, and the feeding channel 3 is aligned with the through hole. The feeding rod 16 extends to the winding table 11, and the length direction of the feeding channel 3 is tangent to the positioning body 12. Specifically, the flat copper strip output from the feeding channel 3 enters between the movable slide body 13 and the positioning body 12 and abuts against the outer edge of the positioning body 12. The feeding rod 16 helps to make the flat copper strip conveyed between the movable slide body 13 and the positioning body 12 flat.

[0035] Reference Figure 3 and Figure 5To facilitate the gradual lifting of the stacked annular coils, the lifting assembly 15 includes a first guide slope 151 and a second guide slope 152. The first guide slope 151 is located on the side of the feed rod 16 in the width direction. Further, the first guide slope 151 is located on the side of the feed channel 3 near the positioning body 12 in the width direction, and the first guide slope 151 slopes downwards in a direction away from the feed channel 3. The second guide slope 152 is located on the side of the sliding body 13 near the positioning body 12, and the second guide slope 152 slopes downwards in a direction close to the positioning body 12. Further, the lowest edges of the first guide slope 151 and the second guide slope 152 are flush with the bottom wall of the feed channel 3. The first guide slope 151 and the second guide slope 152 can be designed as straight slopes or curved slopes as needed, without limitation.

[0036] By setting the first guide slope 151 and the second guide slope 152, each time the flat copper wire is bent around, the bottommost loop coil will bend upwards along the first guide slope 151 and the second guide slope 152, thus lifting it up. This allows the coils to be stacked sequentially during the continuous winding of the flat copper wire, which is simple, quick, and helps to improve the coil stacking accuracy.

[0037] Reference Figure 3 and Figure 5 Furthermore, to prevent unnecessary vertical vibration of the flat copper wire between the sliding body 13 and the positioning body 12 during winding, the sliding body 13 includes an abutment portion 131 and a limiting portion 132. The abutment portion 131 is rectangular and is slidably disposed on the winding table 11 along the circumference of the positioning body 12. The limiting portion 132 is integrally formed on the side of the abutment portion 131 near the positioning body 12, so that the limiting portion 132 extends out of the abutment portion 131, and the abutment portion 131 is close to the positioning body 12. A winding channel 4 is provided on one side for the flat copper wire to pass through. The winding channel 4 is aligned with the feeding channel 3. The winding channel 4 passes through the abutment part 131 near the positioning body 12. The winding channel 4 is located below the limiting part 132. The upper surface of the flat copper wire in the winding channel 4 abuts against the lower surface of the limiting part 132. Furthermore, the width of the winding channel 4 is smaller than the width of the flat copper strip. The second guide slope 152 is located on the upper surface of the limiting part 132 near the positioning body 12. Through the cooperation of the winding channel 4 and the limiting part 132, the flat copper strip is kept stable during winding.

[0038] Reference Figure 4 and Figure 5 Furthermore, the limiting part 132 abuts against the upper surface of the positioning body 12, so that the annular coils above the flat copper wire wound between the abutting part 131 and the positioning body 12 are all located above the first guide slope 151 and the second guide slope 152, and the positioning body 12 will not affect the gradual stacking of the annular coils.

[0039] Reference Figure 3 and Figure 4 To facilitate the reciprocating movement of the movable slide body 13, the movable slide drive component 14 includes a reduction motor 141, a gear 142, a rotary seat 143, and a transmission gear ring 144. The reduction motor 141 is fixedly mounted on the winding table 11. The gear 142 is coaxially fixedly connected to the output shaft of the reduction motor 141. The rotary seat 143 is rotatably mounted on the winding table 11. The rotary seat 143 is annular. The positioning body 12 is located at the center of the rotary seat 143, so that the rotary seat 143 is rotatably sleeved outside the positioning body 12. The abutment part 131 of the movable slide body 13 is fixedly mounted on the surface of the rotary seat 143 by screws. The feeding rod 16 extends above the rotary seat 143. The transmission gear ring 144 is coaxially fixedly sleeved on the rotary seat 143 and meshes with the gear 142.

[0040] During operation, the geared motor 141 is started, driving the gear 142 to rotate. The gear 142 drives the transmission gear ring 144 and the rotating base 143 to rotate, causing the movable sliding body 13 to move circumferentially away from the feeding rod 16 along the positioning body 12, so as to bend the flat copper strip on the positioning body 12. Then, the geared motor 141 is started in reverse to drive the movable sliding body 13 to move in the opposite direction to reset, facilitating the next bending. In other embodiments, the gear 142 and the transmission gear ring 144 can also be replaced by a worm gear and a worm. The worm gear is fixedly sleeved on the outside of the rotating base 143, and the worm is coaxially fixed with the output shaft of the geared motor 141. Using a worm gear and a worm can also achieve the same reciprocating movement of the movable sliding body 13.

[0041] Reference Figure 4 To facilitate the installation of the limiting rod 21, a sliding seat 8 is slidably provided on the second mounting base 7 in the vertical direction. The limiting rod 21 is fixedly installed at the bottom of the sliding seat 8 in the vertical direction. The limiting rod 21 is made of smooth plastic rod with a certain degree of elasticity to avoid damage to the coil. The limiting rod 21 is located above the positioning body 12 and aligned with the center of the positioning body 12. This ensures that during the continuous winding and stacking of flat copper wires, the limiting rod 21 is always aligned with the inside of the wound and stacked annular coil. Thus, when there are many annular coils stacked, it can limit the annular coil and prevent the annular coil from deforming or tilting.

[0042] Reference Figure 4 The limiting drive component 22 is used to drive the sliding seat 8 to move the limiting rod 21 toward or away from the positioning body 12. Specifically, the limiting drive component 22 includes a cylinder fixedly installed on the second mounting seat 7. The cylinder is arranged in a vertical direction, and the sliding seat 8 is fixedly connected to the moving end of the cylinder. In other embodiments, the cylinder can also be replaced by an electric cylinder, an electric push rod, etc.

[0043] During operation, the limiting drive 22 drives the sliding seat 8 to move the limiting rod 21 down to the required position. As the number of layers of the annular coil gradually increases, the limiting rod 21 extends into the wound annular coil to limit the annular coil. When the number of layers of the annular coil reaches the preset number, the limiting drive 22 drives the sliding seat 8 to slide the limiting rod 21 away from the positioning body 12, so that the limiting rod 21 extends out of the annular coil, which facilitates the shearing of the annular coil.

[0044] Reference Figure 4 To facilitate the disassembly, assembly, and adjustment of the first mounting base 6, the second mounting base 7, and the third mounting base 20, multiple annular grooves 23 are formed along the circumference of the mounting plate 5. Each of the first mounting base 6, the second mounting base 7, and the third mounting base 20 is provided with a mating block (not shown in the figure) for sliding along the annular grooves 23 on the mounting plate 5. Each of the first mounting base 6, the second mounting base 7, and the third mounting base 20 is provided with a fixing member for relative fixation to the mounting plate 5, including multiple bolts for connection to the mounting plate 5. The first mounting base 6, the second mounting base 7, and the third mounting base 20 are all fixed to the mounting plate 5 by bolts, facilitating disassembly, assembly, and adjustment as needed. In this invention, the first mounting base 6 and the second mounting base 7 are symmetrically distributed around the center of the mounting plate 5, and the third mounting base 20 is located on the side of the movable slide body 13 opposite to the positioning body 12.

[0045] Reference Figure 4 To facilitate the cutting of the wound annular coil, the cutting mechanism 19 includes an electric clamp 191 and a drive source 192. The electric clamp 191 is slidably mounted on the third mounting base 20, and the sliding direction of the electric clamp 191 is perpendicular to the length direction of the feed rod 16. When the winding channel 4 of the movable slide body 13 is aligned with the feed channel 3, the electric clamp 191 is located on the side of the movable slide body 13 away from the feed rod 16. The drive source 192 is fixedly mounted on the third mounting base 20. Specifically, the drive source 192 can be one of an electric cylinder, an electric push rod, a hydraulic cylinder, etc., and there is no limitation here. The moving ends of the electric clamp 191 and the drive source 192 are fixed.

[0046] Once the annular coil is wound and transported a certain distance away from the feed rod 16, the drive source 192 drives the electric clamp 191 to move toward the annular coil, cutting off the portion of the flat copper wire extending out of the sliding body 13, thus completing the winding of one product.

[0047] Reference Figure 3 and Figure 5To facilitate support of the wound annular coil and convenient product output after completion, the automatic winding and stacking device also includes a first support frame 9 and a second support frame 10 mounted on the ground. The first support frame 9 is located on the side of the winding table 11 away from the third mounting base 20. The first support frame 9 is used to support the annular coil during winding. The first support frame 9 has a support plane 91, which is located on the side of the sliding body 13 away from the feeding rod 16. The support plane 91 is flush with the bottom wall of the winding channel 4. The setting of the first support frame 9 helps to support the annular coil extending from the turntable 143 during winding. When the annular coil is wound, the flat copper wire is conveyed forward and overlapped on the support plane 91. Then it is cut by the cutting mechanism 19. The support plane 91 can support the cut coil.

[0048] Reference Figure 3 and Figure 5 When the winding channel 4 is aligned with the feeding channel 3, the second support frame 10 is located on the side of the support plane 91 away from the feeding rod 16. The second support frame 10 has a guide output plane 101, which is located on the side of the support plane 91 away from the moving slide body 13. The guide output plane 101 is inclined downward in the direction away from the support plane 91, so that the cut annular coil can be fed out along the guide output plane 101.

[0049] Reference Figure 1 and Figure 4 To facilitate the improvement of the automation level of the device, the unwinding machine 172, the limit drive 22, the geared motor 141, the drive source 192 and the electric clamp 191 are all electrically connected to the external control system.

[0050] The implementation principle of the automatic flat copper wire winding and stacking device in Embodiment 1 of the present invention is as follows: During operation, the flat copper wire is unwound and fed out by the unwinder 172. Then, the flat copper wire passes through the conductive sponge 182 for static electricity removal and cleaning. Then, it is straightened and conveyed by multiple first and second guide rollers of the straightening component 183. Next, the flat copper wire is conveyed into the feeding channel 3 of the feeding rod 16 through the through hole in the center of the mounting plate 5. The flat copper wire fed out from the feeding channel 3 enters between the moving slide body 13 and the positioning body 12. The flat copper wire moves a first preset distance. Then, while continuing to convey the flat copper wire, the reduction motor 141 is started. The reduction motor 141 drives the rotary seat 143 to rotate and makes the moving slide body 13 move along the positioning body 12. The sliding body 13 moves circumferentially away from the feed rod 16, causing the movable sliding body 13 to bend the flat copper wire by rotating 90 degrees along the positioning body 12. Then, the reduction motor 141 drives the rotary table 143 to reverse, returning the movable sliding body 13 to its original position. The flat copper wire continues to move a second preset distance. While the flat copper wire continues to be fed, the rotary table 143 is driven to rotate again, causing the movable sliding body 13 to move circumferentially away from the feed rod 16 along the positioning body 12, continuing to bend the flat copper wire by rotating 90 degrees along the positioning body 12. The flat copper wire then continues to be fed forward a third preset distance, repeating the bending steps to gradually wind the flat copper wire into a rectangular loop coil with rounded corners. (Refer to...) Figure 6 Specifically, the first preset distance is the length of the straight segment at the initial end of the flat copper wire, the second preset distance is the length of the straight segment in the width direction of the loop coil, and the third preset distance is the length of the straight segment in the length direction of the loop coil.

[0051] During the bending and winding process, the loop coil brushes past the feed rod 16 and the limiting part 132, and then deflects upward along the first guide slope 151 and the second guide slope 152 to be stacked and lifted. As the number of loop coil stacking layers gradually increases, the limiting rod 21 is located inside the loop coil to limit the loop coil.

[0052] Once the annular coils have stacked to the preset number of layers, the cylinder is activated. The cylinder drives the sliding seat 8 to raise the limiting rod 21, causing the limiting rod 21 to extend out of the annular coil. Then, the flat copper wire continues to be fed forward, causing the coil to move towards the supporting plane 91. After overlapping on the supporting plane 91, the drive source 192 drives the electric clamp 191 to move towards the annular coil, cutting off the portion of the flat copper wire extending beyond the moving slide body 13, thus completing the winding of one product. In this invention, the cooperation of the moving slide body 13, the positioning body 12, and the lifting component 15 ensures that the flat copper wire is wound in an orderly manner, helping to guarantee the stacking accuracy during the winding process. Extending the limiting rod 21 into the annular coil effectively suppresses the tilting and skewing problems of the multi-layer coil structure during the winding process.

[0053] This invention also discloses an automatic winding and stacking method for flat copper wires. The automatic winding and stacking method for flat copper wires, using the aforementioned automatic winding and stacking device, includes the following steps: Step 1: The flat copper wire is unwound and sent out by the unwinder 172. Then the flat copper wire passes through the conductive sponge 182 for static removal and cleaning. Then it is straightened and conveyed by the first guide roller and the second guide roller of the straightening assembly 183. Step 2: The flat copper wire then passes through the through hole and the feeding channel 3 in sequence and enters between the sliding body 13 and the positioning body 12. The flat copper wire moves a first preset distance, where the first preset distance is the preset length of the straight section at the initial end of the flat copper wire. Step 3: While continuing to feed the flat copper wire, start the reduction motor 141. The reduction motor 141 drives the rotary table 143 to rotate, thereby driving the movable slide body 13 to move circumferentially along the positioning body 12. The movable slide body 13 then bends the flat copper wire by rotating 90 degrees along the positioning body 12. The movable slide body 13 then returns to its original position, and the flat copper wire moves forward a second preset distance. Then, while continuing to feed the flat copper wire, the movable slide body 13 is moved circumferentially along the positioning body 12 again, causing the movable slide body 13 to bend the flat copper wire by rotating 90 degrees along the positioning body 12. The flat copper wire then continues to be fed forward a third preset distance. The second preset distance is the preset length of the straight segment in the width direction of the ring coil, and the third preset distance is the preset length of the straight segment in the length direction of the ring coil. Step 4: Repeat step 3 to gradually wind the flat copper wire into a loop. During the winding process, the bottom loop of copper wire brushes past the feed rod 16 and the limiting part 132, and then bends upward under the action of the first guide slope 151 and the second guide slope 152 to lift it up. Step 5: As the number of stacked layers of the loop coil gradually increases, the limiting rod 21 extends into the wound and stacked loop coil to limit the loop coil; Step 6: After the ring coil is stacked to the preset number of layers, the cylinder is activated to drive the sliding seat 8 to move the limit rod 21 out of the ring coil. Then, the flat copper wire is continued to be fed forward. The drive source 192 drives the electric clamp 191 to move towards the ring coil, cutting off the part of the flat copper wire that extends out of the sliding body 13, thus completing the winding of one product.

[0054] Example 2:

[0055] Reference Figure 3 , Figure 7 and Figure 8The difference between this embodiment and embodiment 1 is that the limiting rod 21 is rotatably mounted on the sliding seat 8, and the rotation direction of the limiting rod 21 is perpendicular to the length direction of the feeding rod 16. The sliding seat 8 is provided with a rotating component for driving the limiting rod 21 to rotate toward or away from the support plane 91. Specifically, the rotating component includes a reduction motor 24 fixedly mounted on the sliding seat 8, and rotating shafts 25 are fixedly mounted on both sides of the limiting rod 21. The rotating shafts 25 rotate on the sliding seat 8, and the rotating shafts 25 are coaxially fixed with the output shaft of the reduction motor 24. In other embodiments, the reduction motor 24 can also be replaced by a reduction servo motor.

[0056] Reference Figure 7 and Figure 8 The limiting rod 21 is covered by an airbag 26, and an air supply channel 28 communicating with the airbag 26 is opened inside the limiting rod 21. A miniature blower 27 is fixedly installed on the sliding seat 8, and the blower is connected to the air supply channel 28 through a hose 29. By starting the miniature blower 27 to blow or evacuate air, it helps to inflate or deflate the airbag 26 outside the limiting rod 21.

[0057] The implementation principle of Embodiment 2 of the present invention is as follows: During the winding of the flat copper wire, the rotating component drives the limiting rod 21 to a vertical state, and the micro blower 27 extracts the gas from the air bag 26, making the air bag 26 deflated, so that the limiting rod 21 can limit the annular coil; when the annular coil moves to the support plane 91 and is misaligned with the limiting rod 21, the annular coil located on the support plane 91 is then cut off, and then the cylinder is activated to drive the sliding seat 8 to move down, while the micro blower 27 delivers gas into the air supply channel 28, causing the air bag 26 to inflate. The starting reduction motor 24 drives the limiting rod 21 to rotate toward the direction of the cut annular coil. The end of the rotating limiting rod 21 abuts against the annular coil on the support plane 91 to push the annular coil out along the guide output plane 101. The inflated airbag 26 further prevents the end of the limiting rod 21 from scratching the annular coil. After the annular coil slides out along the guide output plane 101, the reduction motor 24 drives the limiting rod 21 to rotate back to the vertical position. Then the miniature blower 27 extracts the gas from the airbag 26 to facilitate the winding of the next product.

[0058] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
