Description

Technical Field

[0001] This utility model relates to the field of flat copper wire winding technology, and specifically to a winding forming device for a multi-unit flat copper wire winding machine. Background Technology

[0002] Flat copper wire windings (or "flat copper wire coils") are one of the mainstream technologies for drive motors in new energy vehicles, industrial servo systems, and high-end home appliances. The core of this technology is replacing traditional multi-strand round copper wire with rectangular cross-section flat copper wire. Compared to traditional round copper wire, flat copper wire offers advantages such as higher power density, lower losses, better heat dissipation, and superior high-frequency performance when used in motors, transformers, or inductor coils.

[0003] In motors, flat copper wire windings are typically installed one by one. Then, at least two flat copper wire windings are soldered to their leads according to regulations. After the first and last leads of multiple flat copper wire windings are soldered, the remaining two leads are connected to the power supply, thus enabling each flat copper wire winding to be energized. However, this method has the disadvantage of having many soldering points. Furthermore, the surface of the flat copper wire is coated with insulating varnish, but the insulating varnish on the lead ends of the flat copper wire windings needs to be removed before soldering. The manufacturing efficiency of soldering flat copper wire windings is low.

[0004] Inductors use flat copper wire windings. When multiple inductors need to be connected in series, the leads of the flat copper wire windings must be soldered end to end according to regulations. After the remaining two leads of the series-connected inductors are connected to the power supply, each inductor can be energized. However, it also has the disadvantages of multiple soldering positions, removing the insulating varnish from the lead ends before soldering, and low soldering efficiency.

[0005] Therefore, a multi-winding machine for flat copper wire is needed to produce multi-winding finished products of flat copper wire; the flat copper wire windings of this multi-winding finished product can be connected and energized without welding. Furthermore, in order to bend the flat copper wire into windings and connecting wires during the production of multi-winding finished products of flat copper wire, this technical field urgently needs a winding forming device for a multi-winding machine of flat copper wire. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a winding forming device for a multi-unit flat copper wire winding machine.

[0007] The technical solution of this utility model is achieved as follows: a winding forming device for a multi-unit flat copper wire winding machine, comprising: Forming bracket, forming slide, horizontal bending and adjusting component, winding horizontal bending die, connecting wire horizontal bending die, conduit; The forming slide and the forming bracket are connected by the horizontal plane bending and adjusting assembly. The winding horizontal plane bending die and the connecting wire horizontal plane bending die are both installed on the forming slide. The threading tube is rotatably connected to the forming bracket. The horizontal plane bending and adjusting assembly can switch the wire inlet of the winding horizontal plane bending die and the wire inlet of the connecting wire horizontal plane bending die to the wire outlet of the threading tube. The horizontal bending die for winding includes a turntable, a stop block, a limiting block, a bending column, a lifting motion device, and a reciprocating rotary device. The turntable is connected to the forming slide through the reciprocating rotary device. The turntable is provided with a central sliding hole, through which the bending column passes. The bending column is connected to the forming slide through the lifting motion device. The limiting block is fixedly connected to the edge of the turntable, and the stop block is fixedly connected to the upper side of the limiting block. A bending channel is formed between the limiting block, the turntable, and the bending column, and the stop block covers the bending channel.

[0008] Furthermore, one end of the stop block is locked to the upper side of the limiting block by bolts, and the other end of the stop block is provided with an arc-shaped opening, through which the bending column passes with clearance fit.

[0009] Furthermore, it also includes: a right-angle positioning plate, which is fixedly connected to the forming slide and is located above the turntable; the wire guide tube can abut against one right-angle side of the right-angle positioning plate, and the limiting block can abut against the other right-angle side of the right-angle positioning plate.

[0010] Furthermore, it also includes: a wire pressing telescopic assembly and a wire pressing block, wherein the wire pressing block is connected to the forming bracket through the wire pressing telescopic assembly, a clearance groove is provided in the middle of the forming slide, the horizontal bending mold of the connecting wire and the horizontal bending mold of the winding wire are respectively located on the left and right sides of the clearance groove, the wire pressing block is located in front of and above the clearance groove, and the outlet of the wire tube is located in the rear.

[0011] Furthermore, the winding horizontal plane bending die and the connecting line horizontal plane bending die have the same structure.

[0012] Furthermore, the surface of the conduit is provided with a guide slope.

[0013] Compared with the prior art, the beneficial effects or advantages of this utility model are as follows: The straightened flat copper wire is fed into the threading tube of the winding forming device. The horizontal bending die for winding and the horizontal bending die for connecting wire are switched and moved to the outlet of the threading tube according to production requirements. The horizontal bending die for winding bends the flat copper wire coming out of the threading tube into a winding, and then the horizontal bending die for connecting wire bends the flat copper wire coming out of the threading tube into a connecting wire. The bending column has a lifting function. When the bending column descends, the flat copper wire can exit or enter the bending channel by changing the position of the forming slide. When the bending column rises, the bending column and the limiting block cooperate to bend the flat copper wire accordingly. This helps to improve the production efficiency of multi-strand flat copper wire winding products. Attached Figure Description

[0039] See Figures 1 to 23 The preferred embodiment of this utility model.

[0040] A winding forming device for a multi-unit flat copper wire winding machine includes: 21. Forming bracket; 22. Forming slide; 23. Horizontal bending and adjusting assembly; 24. Horizontal bending die for winding; 25. Horizontal bending die for connecting wire; 26. Conduit tube. The forming slide 22 and the forming bracket 21 are connected by the horizontal plane bending and adjusting assembly 23. The winding horizontal plane bending die 24 and the connecting wire horizontal plane bending die 25 are both installed on the forming slide 22. The threading tube 26 is rotatably connected to the forming bracket 21. The inlet of the threading tube 26 is aligned with the clamping port of the second clamping assembly 18. The horizontal plane bending and adjusting assembly 23 can switch the inlet of the winding horizontal plane bending die 24 and the inlet of the connecting wire horizontal plane bending die 25 to be aligned with the outlet of the threading tube 26. The horizontal bending die 24 includes a turntable 241, a stop block 242, a limiting block 243, a bending column 244, a lifting motion device 245, and a reciprocating rotary device 246. The turntable 241 is connected to the forming slide 22 through the reciprocating rotary device 246. The turntable 241 is provided with a central sliding hole. The bending column 244 passes through the central sliding hole. The bending column 244 is connected to the forming slide 22 through the lifting motion device 245. The limiting block 243 is fixedly connected to the edge of the turntable 241. The stop block 242 is fixedly connected to the upper side of the limiting block 243. A bending channel is formed between the limiting block 243, the turntable 241, and the bending column 244. The stop block 242 covers the bending channel.

[0041] The beneficial effects or advantages of this utility model are as follows: The straightened flat copper wire 7 is fed into the threading tube 26 of the winding forming device 2. The horizontal bending die 24 and the horizontal bending die 25 of the connecting wire are switched and moved to the outlet of the threading tube 26 according to production requirements. The horizontal bending die 24 of the winding wire bends the flat copper wire 7 coming out of the threading tube 26 into a winding 71, and then the horizontal bending die 25 of the connecting wire bends the flat copper wire 7 coming out of the threading tube 26 into a connecting wire 72. The bending column 244 has a lifting function. When the bending column 244 descends, the flat copper wire can exit or enter the bending channel by changing the position of the forming slide 22. When the bending column 244 rises, the bending column 244 and the limiting block 243 cooperate to bend the flat copper wire accordingly. This helps to improve the production efficiency of multi-wound flat copper wire products.

[0042] The horizontal bending and adjusting component 23 of the winding forming device 2 changes the position of the forming slide 22, thereby switching the inlet of the horizontal bending die 24 and the inlet of the connecting wire horizontal bending die 25 to the outlet of the threading tube 26. With the position of the threading tube 26 unchanged, the horizontal bending die 24 and the connecting wire horizontal bending die 25 process the flat copper wire sequentially. Specifically, the horizontal bending and adjusting component 23 moves the horizontal bending die 24 to the outlet of the threading tube 26, and the flat copper wire exiting the threading tube 26 is fed into the horizontal bending die 24; the horizontal bending die 24 bends the flat copper wire into a winding. The horizontal bending and adjusting component 23 moves the winding horizontal bending die 24 away from the outlet of the threading tube 26, and then moves the connecting wire horizontal bending die 25 to the outlet of the threading tube 26. The flat copper wire coming out of the threading tube 26 is transferred to the connecting wire horizontal bending die 25; the connecting wire horizontal bending die 25 bends the flat copper wire into a connecting wire.

[0043] The lifting actuator 245 first lowers the bending column 244, with the top of the bending column 244 lower than the upper side of the turntable 241. The horizontal bending and adjusting component 23 moves the winding horizontal bending mold 24 to the outlet of the wire threading tube 26. The flat copper wire coming out of the wire threading tube 26 is fed into the bending channel. The lifting actuator 245 then raises the bending column 244, with the top of the bending column 244 higher than the upper surface of the stop block 242. The reciprocating rotary actuator 246 drives the turntable 241. The limiting block 243 and the bending column 244 cooperate to bend the flat copper wire into the winding.

[0044] The lifting motion device 245 is a telescopic cylinder or an electric push rod; the reciprocating rotary device 246 is a servo motor or a rotary cylinder. For example, when the turntable 241 rotates 90° clockwise, the limit block 243 bends the straightened flat copper wire by 90°. The turntable 241 then rotates 90° counterclockwise, and the limit block 243 returns to its original position. The wire guide tube 26 continues to feed out a section of flat copper wire. When the turntable 241 rotates 90° clockwise again, the limit block 243 bends the straightened flat copper wire by 90° again. The turntable 241 then rotates 90° counterclockwise, and the limit block 243 returns to its original position. The wire guide tube 26 continues to feed out a section of flat copper wire. This process is repeated multiple times, and the flat copper wire is bent into a winding.

[0045] Furthermore, one end of the stop block is locked to the upper side of the limiting block by bolts, and the other end of the stop block is provided with an arc-shaped opening, through which the bending column passes with clearance fit.

[0046] The beneficial effect of this technical solution is that it helps the stop block 242 to better cover the bend in the channel.

[0047] Furthermore, it also includes: a right-angle positioning plate 27, which is fixedly connected to the forming slide 22 and is located above the turntable 241; the wire guide tube 26 can abut against one right-angle side of the right-angle positioning plate 27; and the limiting block 243 can abut against the other right-angle side of the right-angle positioning plate 27.

[0048] The beneficial effects of this technical solution are as follows: When the position of the forming slide 22 changes, when the wire guide tube 26 abuts against one right-angle side of the right-angle positioning plate 27, the outlet of the wire guide tube 26 is aligned with the inlet of the bending die 24 for switching the horizontal plane of the winding, which helps the straightened flat copper wire to be stably fed into the bending channel. When the turntable 241 rotates 90° counterclockwise to return the limiting block to its original position, the limiting block abuts against the other right-angle side of the right-angle positioning plate 27.

[0049] Furthermore, it also includes: a wire pressing telescopic assembly 28 and a wire pressing block 281. The wire pressing block 281 is connected to the forming bracket 21 through the wire pressing telescopic assembly 28. A clearance groove 221 is provided in the middle of the forming slide 22. The horizontal bending mold 25 of the connecting wire and the horizontal bending mold 24 of the winding wire are respectively located on the left and right sides of the clearance groove 221. The wire pressing block 281 is located in front of and above the clearance groove 221. The outlet of the wire tube 26 is located in the rear and above.

[0050] Furthermore, the winding horizontal plane bending die and the connecting line horizontal plane bending die have the same structure.

[0051] The beneficial effects of this technical solution are as follows: When switching the positions of the horizontal bending die 24 and the horizontal bending die 25, the pressure block 281 is responsible for pressing the flat copper wire, ensuring that the flat copper wire is accurately guided into the die. Before the vertical bending die 34 bends the connecting wire, the flat copper wire coming out of the threading tube 26 is first moved to a position directly above the clearance groove 221; during the 180° rotation of the threading tube 26 and the flat copper wire, the flat copper wire does not contact the clearance groove 221.

[0052] The lifting motion device 245 first lowers the bending column 244. Driven by the horizontal bending adjustment component 23, the flat copper wire coming out of the wire guide tube 26 moves from the bending channel to the avoidance groove 221. The wire pressing telescopic component 28 causes the wire pressing block 281 to press the flat copper wire. The horizontal bending die 25 of the connecting wire is moved to the outlet of the wire guide tube 26. The flat copper wire enters the bending channel of the horizontal bending die 25 of the connecting wire. The wire pressing telescopic component 28 causes the wire pressing block 281 to rise and disengage from the flat copper wire.

[0053] The wire pressing telescopic assembly 28 includes a telescopic cylinder, the cylinder body of which is fixedly connected to the forming bracket, and the telescopic rod of which is fixedly connected to the wire pressing block.

[0054] The horizontal bending die 25 for connecting wires has the same structure as the horizontal bending die 24 for winding wires. The horizontal bending die 25 for connecting wires also includes a turntable, a stop block, a limit block, a bending column, a lifting motion device, and a reciprocating rotary device. The working method is different from that of the horizontal bending die 24 for winding wires. The difference is that the limit block of the horizontal bending die for connecting wires only bends the flat copper wire twice. For example, when the turntable rotates 90° counterclockwise, the limit block bends the straightened flat copper wire by 90°. When the turntable rotates 90° clockwise again, the limit block returns to its original position, and the wire feeding tube continues to feed out a section of flat copper wire. When the turntable rotates 90° counterclockwise again, the limit block bends the straightened flat copper wire by 90° again. When the turntable rotates 90° clockwise again, the limit block returns to its original position. At this time, the connecting wire is obtained, and the wire feeding tube stops feeding out the flat copper wire. Here, the bending direction of the connecting wire made of flat copper wire is opposite to the bending direction of the winding made of flat copper wire.

[0055] Furthermore, the surface of the conduit is provided with a guide slope.

[0056] The beneficial effects of this technical solution are as follows: During the process of bending the flat copper wire into a winding, the bent flat copper wire passes through the conduit 26 and can smoothly move above the conduit 26 upon contact with the guide inclined surface 261, which helps to complete the subsequent winding action. Furthermore, during the winding process, the bent flat copper wire moves above the right-angle positioning plate.

[0057] The horizontal bending and positioning assembly 23 includes a servo motor and a ball screw. The rotational motion of the output shaft of the servo motor causes the forming slide 22 to move linearly through the ball screw. The left and right movement of the forming slide 22 changes the relative position of the winding horizontal bending die 24, the connecting wire horizontal bending die 25 and the flat copper wire coming out of the wire guide tube 26.

[0058] The following describes the application of the winding forming device of this utility model to a multi-unit winding machine for flat copper wire.

[0059] A multi-unit flat copper wire winding machine, comprising: Straightening device 1, winding forming device 2, connecting wire bending device 3, wire cutting device 4; The description of the winding forming device 2 is given above; The straightening device 1 includes a straightening bracket 11, a straightening slide 12, a straightening wheel assembly 13, a pulling drive assembly 14, a spinning drive assembly 15, a flat copper wire coil loading frame 16, a first clamping assembly 17, and a second clamping assembly 18. The straightening slide 12 is connected to the straightening bracket 11 via the pulling drive assembly 14. The straightening wheel assembly 13 is connected to the straightening slide 12 via the spinning drive assembly 15. The flat copper wire coil loading frame 16 is fixedly connected to the straightening wheel assembly 13. The outlet of frame 16 is aligned with the inlet of the straightening wheel assembly 13. The first clamping assembly 17 is fixedly connected to the straightening slide 12, and the clamping port of the first clamping assembly 17 is aligned with the outlet of the straightening wheel assembly 13. The second clamping assembly 18 is fixedly connected to the straightening bracket 11, and the second clamping assembly 18 is spaced apart from the first clamping assembly 17. The clamping port of the second clamping assembly 18 is aligned with the clamping port of the first clamping assembly 17. The forming bracket 21 is fixedly connected to the straightening bracket 11. The connecting line bending device 3 includes a bending bracket 31, a bending space moving component 32, a base plate 33, a connecting line vertical bending die 34, a first lifting and pressing component 35, and a second lifting and pressing component 36. The bending bracket 31 is fixedly connected to the forming bracket 21. The base plate 33 is connected to the bending bracket 31 through the bending space moving component 32. The connecting line vertical bending die 34, the first lifting and pressing component 35, and the second lifting and pressing component 36 are all installed on the base plate 33. The first lifting and pressing component 35 and the second lifting and pressing component 36 are respectively located on the left and right sides of the connecting line vertical bending die 34. The wire cutting device 4 is located between the winding forming device 2 and the connecting wire bending device 3. The wire cutting device 4 includes a wire cutting bracket 41, a wire cutting moving component 42, and a wire cutting blade 43. The wire cutting bracket 41 is fixedly connected to the forming bracket 21, and the wire cutting blade 43 is connected to the wire cutting bracket 41 through the wire cutting moving component 42.

[0060] The material pulling drive assembly 14 of the straightening device 1 causes the straightening slide 12 to move back and forth. The flat copper wire is straightened by the cooperation of the straightening wheel assembly 13, the first clamping assembly 17, and the second clamping assembly 18. The straightened flat copper wire is fed into the winding forming device 2. The amount of flat copper wire fed can be controlled, which helps to improve production efficiency.

[0061] The straightened flat copper wire 7 is fed into the threading tube 26 of the winding forming device 2. The horizontal bending die 24 and the horizontal bending die 25 of the connecting wire are switched and moved to the outlet of the threading tube 26 according to the process requirements. The horizontal bending die 24 of the winding wire bends the flat copper wire 7 coming out of the threading tube 26 into a winding 71. Then, the horizontal bending die 25 of the connecting wire bends the flat copper wire 7 coming out of the threading tube 26 into a connecting wire 72. Finally, the vertical bending die 34 of the connecting wire bending device 3 then... The connecting wire 72 is bent at a specified angle, and the flat copper wire 7 coming out of the conduit 26 returns to the bending die 24 on the winding horizontal plane to generate the next winding 71; this process is repeated, and after generating the required number of windings 71, the flat copper wire 7 coming out of the conduit 26 is cut to obtain the finished product of multi-connection flat copper wire winding; the flat copper wire windings and connecting wires are all made from the same flat copper wire through bending, so the flat copper wire windings can be connected and energized without welding, and are produced by corresponding devices, resulting in high production efficiency.

[0062] The flat copper wire passes sequentially through the straightening wheel assembly 13, the first clamping assembly 17, and the second clamping assembly 18. When the first clamping assembly 17 releases the flat copper wire and the second clamping assembly 18 clamps the flat copper wire, the pulling drive assembly 14 moves the straightening slide 12 toward the flat copper wire winding loading frame 16, pulling the flat copper wire out of the flat copper wire winding loading frame 16, and the straightening wheel assembly 13 straightens the flat copper wire. When the first clamping assembly 17 clamps the flat copper wire and the second clamping assembly 18 releases the flat copper wire, the pulling drive assembly 14 moves the straightening slide 12 toward the second clamping assembly 18, feeding the straightened flat copper wire into the winding forming device 2. When the flat copper wire coming out of the outlet of the flat copper wire loading frame 16 is pulled outward, the flat copper wire roll rotates and is thus fed outward; when the pulling of the flat copper wire stops, the flat copper wire roll does not rotate.

[0063] The horizontal bending and adjusting component 23 moves the horizontal bending die 25 away from the outlet of the threading tube 26, and the bending space moving component 32 moves the vertical bending die 34 of the connecting wire to contact the connecting wire. When the winding approaches the first lifting and pressing component 35, the first lifting and pressing component 35 first presses down on the left end of the connecting wire, the second lifting and pressing component 36 moves upward away from the right end of the connecting wire, the first clamping component 17 releases the flat copper wire, and the vertical bending die 34 of the connecting wire then bends the right end of the connecting wire. During the bending process, the spinning drive component 15 causes the straightening wheel component 13 and the flat copper wire winding loading frame 16 to rotate forward simultaneously, rotating the threading tube 26 and the flat copper wire forward by a specified angle. The bending space moving component 32 causes the vertical bending die 34 of the connecting wire to move in space synchronously with the change in the angle of the flat copper wire. When the winding approaches the second lifting and pressing assembly 36, the second lifting and pressing assembly 36 first presses down on the right end of the connecting wire, the first lifting and pressing assembly 35 moves upward away from the left end of the connecting wire, the first clamping assembly 17 releases the flat copper wire, and the vertical bending die 34 of the connecting wire then bends the left end of the connecting wire. During the bending process, the spinning drive assembly 15 causes the straightening wheel assembly 13 and the flat copper wire winding frame to rotate in opposite directions simultaneously, rotating the wire guide tube 26 and the flat copper wire in opposite directions by a specified angle. The bending space movement assembly 32 causes the vertical bending die 34 of the connecting wire to move synchronously in space as the angle of the flat copper wire changes.

[0064] The lifting and pressing assembly of the connecting wire bending device 3 first presses one end of the connecting wire, and then the vertical bending die 34 of the connecting wire bends the other end of the connecting wire. The flat copper wire coming out of the wire tube 26 does not move left or right but can rotate at a specified angle. During the rotation of the flat copper wire, the vertical bending die 34 of the connecting wire moves synchronously in space to facilitate the bending process and improve the bending quality.

[0065] According to actual production, the vertical bending die 34 of the connecting wire can bend the left end of the connecting wire by 180° or the right end of the connecting wire by 180°. The winding and the vertical bending die 34 of the connecting wire are spatially translated, and the winding does not rotate to facilitate subsequent winding forming. After the connecting wire is vertically bent, the flat copper wire returns to the horizontal bending die of the winding. After the flat copper wire is straightened, the first clamping assembly clamps the flat copper wire, and with the help of the pulling drive assembly, the wire feeding tube continues to feed out the flat copper wire.

[0066] During the production process, the horizontal bending die 24 bends the flat copper wire into the required winding. The straightened flat copper wire is then fed into the horizontal bending die 24 through the threading tube 26 according to process requirements. The threading tube 26 serves to guide the flat copper wire and hold it in place during bending. The horizontal bending die 25 bends the straightened flat copper wire into a connecting wire, which distinguishes the windings and connects them. The vertical bending die 34 bends the connecting wire into a specified angle, such as 180°, in the vertical plane. The vertically bent connecting wire shortens the horizontal distance between adjacent windings, making the structure of the multi-connected flat copper wire winding product more compact. The vertically bent connecting wire also increases the vertical distance between adjacent windings, thus helping the previously bent windings avoid the horizontal bending die 24 when processing the next winding, preventing interference with the processing of the next winding.

[0067] The flat copper wire multi-wound finished product produced by this utility model has multiple windings, and the adjacent two windings are connected by connecting wires, eliminating the need to weld the adjacent two windings together; after the lead end of the first winding and the lead end of the last winding of the flat copper wire multi-wound finished product are connected to the power supply, the multiple windings can be energized.

[0068] For example, when there are five windings and four connecting wires, the finished product is a five-strand flat copper wire winding product. Specifically, the straightened flat copper wire coming out of the threading tube 26 first enters the horizontal bending die 24, where it is bent into the first winding. Then, the straightened flat copper wire coming out of the threading tube 26 enters the horizontal bending die 25, where it is bent into the first connecting wire. The vertical bending die 34 then bends the first connecting wire vertically by 180°. During this bending process, the threading tube 26 and the flat copper wire rotate 180° accordingly, while the first winding does not rotate. However, the position of the first winding and the vertical plane of the connecting wire remain the same. The position of the bending die 34 is adjusted synchronously to ensure smooth bending. The vertical bending die 34 of the connecting wire is away from the first connecting wire after bending. The straightened flat copper wire coming out of the wire tube 26 re-enters the horizontal bending die 24 of the winding to obtain the second winding, and then re-enters the horizontal bending die 25 of the connecting wire to obtain the second connecting wire. The vertical bending die 34 of the connecting wire bends the second connecting wire again. This process is repeated to obtain the third winding, the third connecting wire, and the third connecting wire is bent to obtain the fourth winding, the fourth connecting wire, and the fourth connecting wire is bent to obtain the fifth winding. Finally, the flat copper wire coming out of the wire tube 26 is cut to obtain the finished five-strand flat copper wire winding.

[0069] When the flat copper wire is bent, the wire cutting tool 43 is in its initial position, at which point it does not interfere with the flat copper wire. After the finished product is made, the position of the forming slide 22 is adjusted so that the flat copper wire coming out of the wire guide tube 26 is above the wire avoidance groove 221. At this time, the wire cutting moving component 42 moves the wire cutting tool 43 to the position of the wire avoidance groove 221, and the wire cutting tool 43 cuts the flat copper wire. The finished product falls onto the discharge conveyor belt 62 and is finally sent to the receiving frame by the discharge conveyor belt 62.

[0070] The wire cutting movement assembly 42 includes a servo motor and a ball screw. The rotational motion of the output shaft of the servo motor causes the wire cutting cutter 43 to move linearly through the ball screw. The wire cutting cutter 43 is a pneumatic scissor.

[0071] The straightening roller assembly 13 includes a support plate 131, a first rotating shaft 132, a second rotating shaft 133, a transverse support plate 134, a transverse straightening roller 135, a vertical support plate 136, and a vertical straightening roller 137. The rear end of the support plate 131 is fixedly connected to the front end of the first rotating shaft 132, and the front end of the support plate 131 is fixedly connected to the rear end of the second rotating shaft 133. The first rotating shaft 132 is provided with a first threading center hole, and the second rotating shaft 133 is provided with a second threading center hole 1331. The transverse straightening roller 135 is rotatably connected to the transverse support plate 134, and the vertical straightening roller 137 is connected to the vertical support plate. The horizontal support plate 134 and the vertical support plate 136 are both fixedly connected to the bearing plate 131. A first bearing is provided between the rear end of the first rotating shaft 132 and the rear end of the straightening slide 12. A second bearing is provided between the front end of the second rotating shaft 133 and the front end of the straightening slide 12. The rear end of the first rotating shaft 132 is also fixedly connected to the flat copper wire winding loading frame 16. The spinning drive assembly 15 is connected to the first rotating shaft 132 through a transmission device. The first wire threading center hole is the wire inlet of the straightening wheel assembly 13, and the second wire threading center hole 1331 is the wire outlet of the straightening wheel assembly 13.

[0072] As can be seen from the above description, the above is a preferred structure of the straightening roller assembly 13. After the flat copper wire coming out of the flat copper wire coil loading frame 16 is straightened by the horizontal straightening roller 135 and the vertical straightening roller 137, it reaches the first clamping assembly 17 and the second clamping assembly 18, thereby improving the straightening effect.

[0073] The straightening device 1 further includes an auxiliary spinning assembly 19, which includes a circular plate 191, a support base 192, support wheels 193, and a reinforcing shaft 194. The front side of the circular plate 191 is fixedly connected to the rear end of the reinforcing shaft 194, the front end of the reinforcing shaft 194 is fixedly connected to the rear end of the first rotating shaft 132, and the rear side of the circular plate 191 is fixedly connected to the flat copper wire coil loading frame 16. The support base 192 is fixedly connected to the straightening slide 12. The two support wheels 193 are respectively rotatably disposed at the left and right ends of the support base 192. The arc surface of the circular plate 191 is placed on the two support wheels 193. Both the circular plate 191 and the reinforcing shaft 194 are provided with auxiliary threading center holes, which are aligned with the wire outlet of the flat copper wire coil loading frame 16 and the first threading center hole.

[0074] As described above, the auxiliary spinning assembly 19 is used to improve the stability of the flat copper wire coil loading frame 16 during rotation. When the connecting wire is bent by the vertical bending die 34, the wire guide tube 26 and the flat copper wire need to rotate accordingly to ensure smooth bending. At this time, the flat copper wire coil loading frame 16 and the straightening wheel assembly 13 also need to rotate accordingly, and the degree of rotation is controlled by the spinning drive assembly 15.

[0075] The horizontal support plate 134 is located at the rear end of the bearing plate 131, and the vertical support plate 136 is located at the front end of the bearing plate 131. Multiple horizontal straightening rollers 135 are arranged in two rows and staggered on the horizontal support plate 134, and multiple vertical straightening rollers 137 are arranged in two rows and staggered on the vertical support plate 136. In this embodiment, there are eleven horizontal straightening rollers 135 and eleven vertical straightening rollers 137, arranged in a staggered layout of six rollers in one row and five rollers in the other. The drawn flat copper wire is straightened by the rolling action of the multiple horizontal straightening rollers 135 and the multiple vertical straightening rollers 137.

[0076] The material pulling drive assembly 14 is a servo linear motor. A linear guide rail 141 is provided between the straightening slide 12 and the straightening bracket 11. The servo linear motor drives the straightening slide 12 to move back and forth along the linear guide rail 141. Both the first clamping assembly 17 and the second clamping assembly 18 are pneumatic clamping fingers.

[0077] As described above, the servo linear motor precisely controls the amount of flat copper wire fed. Pneumatic grippers, also known as pneumatic fingers or pneumatic chucks, are actuators that use compressed air as power to grip or grasp workpieces.

[0078] The spinning drive assembly 15 includes a servo rotary motor. The transmission includes a driving gear and a driven gear. The center of the driven gear is fixedly connected to the first rotating shaft. The driving gear meshes with the driven gear. The output shaft of the servo rotary motor is fixedly connected to the center of the driving gear. The body of the servo rotary motor is fixedly connected to the straightening slide. The servo rotary motor precisely controls the rotation angle of the first rotating shaft, the support plate, and the flat copper wire.

[0079] The vertical bending die 34 bends the connecting wire to increase the vertical distance between the winding and the flat copper wire coming out of the conduit 26. This distance is higher than the height of the stop block 242. In this way, when the flat copper wire coming out of the conduit 26 enters the bending channel of the horizontal bending die 24 for the processing of the next winding, the previously completed winding moves above the stop block 242 and does not come into contact with the stop block 242, thus not interfering with the processing of the next winding.

[0080] The vertical bending die 34 for the connecting line includes a bending servo rotary motor 341, a drive shaft 342, a central bending rod 343, and an eccentric bending rod 344. The base plate 33 is provided with a rotating hole, through which the drive shaft 342 passes. The output end of the bending servo rotary motor 341 is connected to the front end of the drive shaft 342 via a coupling. The central bending rod 343 and the eccentric bending rod 344 are both fixedly connected to the end face of the rear end of the drive shaft 342.

[0081] As described above, the central bending rod 343 is located on the axis of the drive shaft 342, and the eccentric bending rod 344 moves around the central bending rod 343 with the drive shaft 342. The connecting line is fed between the central bending rod 343 and the eccentric bending rod 344, and the central bending rod 343 and the eccentric bending rod 344 cooperate to bend the connecting line.

[0082] When the eccentric bending rod 344 is in its original position, it is directly above the central bending rod 343. The connecting line enters between the central bending rod 343 and the eccentric bending rod 344. When bending the left end of the connecting line, the bending servo rotary motor 341 causes the drive shaft 342 to rotate 180° in the forward direction. After completing this bend, the bending space moving component 32 moves the vertical bending die 34 away from the connecting line, and the bending servo rotary motor 341 then causes the drive shaft 342 to rotate 180° in the reverse direction, returning the eccentric bending rod 344 to its original position. When bending the right end of the connecting line, the bending servo rotary motor 341 causes the drive shaft 342 to rotate 180° in the reverse direction. After completing this bend, the bending space moving component 32 moves the vertical bending die 34 away from the connecting line, and the bending servo rotary motor 341 then causes the drive shaft 342 to rotate 180° in the forward direction, returning the eccentric bending rod 344 to its original position.

[0084] As can be seen from the above description, depending on whether the left end or the right end of the connecting line is bent, the first or second pressure plate is controlled to press the connecting line to ensure the bending quality.

[0085] When the first telescopic cylinder 351 causes the first pressure plate 352 to press down on the left end of the connecting line, the first pressure plate 352 is adjacent to the left side of the eccentric bending rod 344; when the second telescopic cylinder 361 causes the second pressure plate 362 to press down on the right end of the connecting line, the second pressure plate 362 is adjacent to the right side of the eccentric bending rod 344.

[0086] The bending space movement component 32 includes an X-axis track 321, an X-axis servo slide 322, a Y-axis track 323, a Y-axis servo slide 324, a Z-axis track 325, and a Z-axis servo slide 326.

[0087] The bending space movement assembly 32 also includes an angle adjustment plate 327 and an angle servo rotary motor 328. The body of the angle servo rotary motor 328 is fixedly connected to the lower side of the Y-axis servo slide 324. The angle adjustment plate 327 is located above the Y-axis servo slide 324. The output shaft of the angle servo rotary motor 328 is fixedly connected to the lower side of the angle adjustment plate 327.

By precisely controlling the rotation angle of the angle adjustment plate 327 through the angle servo rotary motor 328, the angle of the vertical bending die 34 of the connecting line can be controlled according to the actual process requirements to complete the required bending of the connecting line.

[0088] It also includes a PLC control device (not shown), which is electrically connected to the straightening device 1, winding forming device 2, connecting wire bending device 3, wire cutting device 4, and material-supporting robot device 5.

The material-supporting bracket is fixedly connected to the forming bracket 21, and the material-supporting mechanical gripper 51 is connected to the material-supporting bracket via the material-supporting space movement component. The material-supporting mechanical gripper 51 is located above the forming slide 22. The material-supporting mechanical gripper 51 is used to grip the first winding and adopts existing technology products such as pneumatic grippers. The material-supporting space movement component is an existing XYZ three-axis movement and rotation component. The material-supporting robotic arm device is used to straighten the folded winding and continuously move in space following the trajectory of the next winding that is being folded, preventing the winding from tilting or falling over as it is folded higher and higher.

[0090] In this invention, the horizontal bending die 25 of the winding forming device 2 is used to bend flat copper wire into a connecting wire. At this time, the bending direction of the connecting wire made from the flat copper wire is opposite to the bending direction of the winding made from the flat copper wire. In another embodiment of this invention, according to actual process needs, the horizontal bending die 25 of the connecting wire can be paused. By setting the operating parameters in the PLC control device, the horizontal bending die 24 of the winding is selected to make the connecting wire. At this time, the length of the flat copper wire coming out of the wire tube 26 is increased, that is, the feeding amount of the flat copper wire is set to the feeding amount used for processing the connecting wire. The horizontal bending die 24 of the winding only bends this flat copper wire twice. At this time, the bending direction of the connecting wire made from the flat copper wire is the same as the bending direction of the winding made from the flat copper wire. Then, the PLC control device makes the horizontal bending die 24 of the winding return to the state of processing the winding, and the feeding amount of the flat copper wire becomes the feeding amount used for processing the winding.

[0091] Based on the same technical concept, this embodiment provides an automated production process for multi-section winding of flat copper wire, including the following steps: Step 1: Install the flat copper wire coil into the straightening device 1; Step 2: Pull out the flat copper wire 7 from the flat copper wire coil. After passing through the straightening wheel assembly 13 of the straightening device 1, the flat copper wire 7 is fed into the winding forming device 2. Step 3: The straightened flat copper wire 7 first enters the wire tube 26 of the winding forming device 2. The flat copper wire 7 coming out of the wire tube 26 then enters the horizontal bending die 24 of the winding forming device 2. The horizontal bending die 24 bends the flat copper wire 7 into a winding 71. Then the wire tube 26 stops feeding out the flat copper wire 7. Step 4: The flat copper wire 7 coming out of the threading tube 26 leaves the winding horizontal plane bending mold 24 and moves to the connecting line horizontal plane bending mold 25 of the winding forming device 2. The threading tube 26 continues to feed out the flat copper wire 7, and the connecting line horizontal plane bending mold 25 bends the flat copper wire 7 into a connecting line 72. The threading tube 26 then stops feeding out the flat copper wire 7. Step 5: The flat copper wire 7 coming out of the conduit 26 leaves the horizontal bending die 25 of the connecting wire, and the connecting wire 72 is fed into the connecting wire bending device 3; Step 6: The lifting and pressing assembly of the connecting wire bending device 3 first presses the connecting wire 72 close to the winding 71. Then, the vertical bending die 34 of the connecting wire bending device 3 bends the connecting wire 72 away from the winding 71. During the bending process, the wire tube 26 and the flat copper wire 7 are rotated by a specified angle. The vertical bending die 34 of the connecting wire also moves synchronously in space as the angle of the flat copper wire 7 changes. Step 7: After bending, the connecting wire 72 leaves the connecting wire bending device 3. The flat copper wire 7 coming out of the wire tube 26 enters the winding horizontal plane bending die 24. Then, the material-supporting robot device 5 clamps the winding 71. The wire tube 26 continues to feed out the flat copper wire 7. The winding horizontal plane bending die 24 bends the flat copper wire 7 into the next winding 71. The material-supporting robot device 5 moves along the horizontal plane bending trajectory of the next winding 71. Then, the wire tube 26 stops feeding out the flat copper wire 7. Step 8: If the number of windings 71 does not reach the set threshold, proceed to step 4; if the number of windings 71 reaches the set threshold, the finished product is obtained, and proceed to step 9. Step 9: The wire feeding tube 26 continues to feed out the flat copper wire 7 until the finished product leaves the winding and forming device 2. The wire cutting device 4 moves from the initial position toward the flat copper wire 7 and then cuts the flat copper wire 7. Finally, the wire cutting device 4 returns to the initial position, and the finished product falls onto the discharge conveyor belt 62.

[0092] The horizontal bending die 24 rotates 90° clockwise when bending the flat copper wire and 90° counterclockwise when resetting; the horizontal bending die 25 rotates 90° counterclockwise when bending the flat copper wire and 90° clockwise when resetting; the specified angle is 180°; the set threshold is five.

[0093] This utility model provides a winding forming device for a flat copper wire multi-unit winding machine. Its purpose is to be applied to the flat copper wire multi-unit winding machine to bend flat copper wire into windings and connecting wires for producing finished flat copper wire multi-unit winding products. It overcomes the shortcomings of the prior art where flat copper wire windings need to be welded together to be connected and energized, the need to remove insulating varnish before welding, and the low efficiency of welding. This utility model adopts a completely new technical approach to produce finished flat copper wire multi-unit winding products, where the flat copper wire windings can be connected and energized without welding. The overall concept is as follows: A straightened flat copper wire is sequentially passed through the horizontal bending die 24 and the horizontal bending die 25 of the connecting wire in the winding forming device 2, and the vertical bending die 34 of the connecting wire in the connecting wire bending device 3, to obtain the required windings and connecting wires. This process is repeated to obtain the finished flat copper wire multi-unit winding product. Finally, the straightened flat copper wire is cut.

[0094] The working process of the flat copper wire multi-unit winding machine is as follows: (1) Flat copper wire coil loading: The flat copper wire coil is installed on the straightening device 1; (2) Flat copper wire straightening: The second clamping component 18 clamps the flat copper wire, and after the first clamping component 17 releases the flat copper wire, the pulling drive component 14 causes the straightening slide 12 to move backward. The flat copper wire pulled out from the flat copper wire coil loading frame 16 passes through the horizontal straightening roller 135 and the vertical straightening roller 137. The horizontal straightening roller 135 and the vertical straightening roller 137 straighten the bent flat copper wire; (3) Feeding: After the second clamping component 18 is released and the first clamping component 17 clamps the flat copper wire, the pulling drive component 14 causes the straightening slide 12 to move forward and feed the flat copper wire into the winding forming. (4) First winding: The horizontal bending and adjusting component 23, the winding horizontal bending mold 24, and the material pulling drive component 14 cooperate to bend the flat copper wire into the first rectangular winding according to the set action requirements of the PLC control device; (5) Folding into connecting wire: The horizontal bending and adjusting component 23, the connecting wire horizontal bending mold 25, and the material pulling drive component 14 cooperate to bend the connecting wire between the windings according to the set action requirements; (6) Connecting wire bending 180°: The bending space moving component 32 of the connecting wire bending device 3 inserts the center bending rod 343 and the eccentric bending rod 344 of the vertical bending mold 34 into the connecting wire according to the signal of the PLC control device. The corresponding lifting and pressing component presses down on the connecting wire, and the bending servo rotary motor 341 makes the drive shaft 342 rotate 180°. At the same time, the spinning drive component 15 makes the straightening wheel component 13, the flat copper wire and the wire tube 26 rotate 180°. During the rotation, the bending space movement component 32 controls the vertical bending mold 34 of the connecting wire to move synchronously in space according to the angle change of the flat copper wire, so as to realize the five-axis linkage and smoothly bend the connecting wire 180°; (7) Second winding: the horizontal bending adjustment component 23, the winding horizontal bending mold 24 and the pulling drive component 14 cooperate to bend the flat copper wire into the second rectangular winding according to the set action requirements of the PLC control device, and at the same time support the material. The robotic arm device 5 clamps the first rectangular winding and moves continuously according to the bending trajectory of the second rectangular winding to straighten the already bent winding and prevent the winding from tilting and falling over as it is bent higher and higher; (8) Third to fifth winding: Repeat steps (5) to (7) three times to fold out the third rectangular winding, the fourth rectangular winding, the fifth rectangular winding and the connecting line between them in sequence; to obtain the flat copper wire five-link winding finished product; (9) The material pulling drive component 14 sends the flat copper wire five-link winding finished product to the wire cutting device 4. The pneumatic scissors of the wire cutting device 4 cut the flat copper wire between the flat copper wire five-link winding finished product and the wire tube 26. The flat copper wire five-link winding finished product falls onto the discharge conveyor belt and is sent out to the receiving frame.
