Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flat copper wire winding processing, in particular to a kind of flat copper wire multi-union winding automatic production process. BACKGROUND

[0002] Flat copper wire winding (or "flat copper wire coil") is one of the mainstream technical routes of new energy vehicles, industrial servo and high-end household appliance drive motor, and its core is to replace traditional multi-strand round copper wire with rectangular cross-section flat copper wire. Compared with traditional round copper wire, flat copper wire has the characteristics of high power density, low loss, good heat dissipation, high frequency performance, etc. in motor, transformer or inductor coil.

[0003] Usually in the motor, first install the flat copper wire winding one by one, then weld the lead ends of at least two flat copper wire windings according to the regulations, after the lead ends of multiple flat copper wire windings are welded, the remaining two lead ends are connected to the power supply, so that each flat copper wire winding can be powered on. However, this method has the disadvantages of multiple welding positions, and the surface of the flat copper wire is coated with insulating paint, but the insulating paint on the lead end of the flat copper wire winding needs to be removed before welding, and the manufacturing efficiency of welding between flat copper wire windings is low.

[0004] When multiple inductor coils are connected in series, the lead ends of the flat copper wire winding are connected end-to-end according to the regulations, and after the remaining two lead ends of the series-connected inductor coils are connected to the power supply, each inductor coil can be powered on. However, the same disadvantages exist, such as multiple welding positions, removal of insulating paint on the lead end before welding, and low welding manufacturing efficiency.

[0005] Therefore, in order to produce flat copper wire multi-union winding products, the flat copper wire windings of the flat copper wire multi-union winding products do not need to be connected and powered on without welding, and the technical field urgently needs a flat copper wire multi-union winding automatic production process. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a kind of flat copper wire multi-union winding automatic production process.

[0007] The technical solution of the present application is as follows: a kind of flat copper wire multi-union winding automatic production process, comprising the following steps: Step one, install the flat copper wire coil stock in the straightening device; Step two, pull out the flat copper wire from the flat copper wire coil stock, and after the flat copper wire passes through the straightening wheel assembly of the straightening device, it is sent into the winding forming device; Step 3: The straightened flat copper wire first enters the wire threading tube of the winding forming device. The flat copper wire coming out of the wire threading tube then enters the horizontal bending die of the winding forming device. The horizontal bending die bends the flat copper wire into a winding. Then the wire threading tube stops feeding out the flat copper wire. Step 4: The flat copper wire coming out of the threading tube leaves the horizontal bending die of the winding and moves to the horizontal bending die of the connecting wire of the winding forming device. The threading tube continues to feed out the flat copper wire, and the horizontal bending die of the connecting wire bends the flat copper wire into a connecting wire. The threading tube then stops feeding out the flat copper wire. Step 5: The flat copper wire coming out of the conduit leaves the horizontal bending die of the connecting wire and is fed into the connecting wire bending device; Step 6: The lifting and pressing assembly of the connecting wire bending device first presses the connecting wire close to the winding. Then, the vertical bending die of the connecting wire bending device bends the connecting wire away from the winding. During the bending process, the wire tube and the flat copper wire are rotated by a specified angle. The vertical bending die of the connecting wire also moves synchronously in space as the angle of the flat copper wire changes. Step 7: After bending, the connecting wire leaves the connecting wire bending device. The flat copper wire coming out of the wire tube enters the horizontal bending die of the winding. Then, the material-supporting robot clamps the winding. The wire tube continues to feed out the flat copper wire. The horizontal bending die of the winding bends the flat copper wire into the next winding. The material-supporting robot moves along the horizontal bending trajectory of the next winding. The wire tube then stops feeding out the flat copper wire. Step 8: If the number of windings does not reach the set threshold, proceed to step 4; if the number of windings reaches the set threshold, the finished product is obtained, and proceed to step 9. Step 9: The wire feeding tube continues to feed out the flat copper wire until the finished product leaves the winding and forming device. The wire cutting device moves from the initial position toward the flat copper wire and then cuts the flat copper wire. Finally, the wire cutting device returns to the initial position, and the finished product falls onto the discharge conveyor belt.

[0008] Compared with the prior art, the beneficial effects or advantages of the present invention 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 wires are switched and moved to the outlet of the threading tube according to process requirements. The horizontal bending die for winding bends the flat copper wire coming out of the threading tube into a winding. Then, the horizontal bending die for connecting wires bends the flat copper wire coming out of the threading tube into a connecting wire. The vertical bending die for connecting wires then bends the connecting wire at a specified angle. The flat copper wire coming out of the threading tube returns to the horizontal bending die for winding to generate the next winding. This process is repeated until the required number of windings are generated. Then, the flat copper wire coming out of the threading tube is cut to obtain a multi-connection flat copper wire winding product. Since both the flat copper wire windings and the connecting wires are formed by bending the same flat copper wire, the flat copper wire windings of the present invention can be connected and energized without welding. Production is carried out by corresponding devices, resulting in high production efficiency. Attached Figure Description

[0034] See Figures 1 to 23 The preferred embodiment of the present invention.

[0035] An automated production process for multi-strand winding of flat copper wire includes 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.

[0036] The beneficial effects or advantages of the present invention 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 the process requirements. The horizontal bending die 24 of the winding 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 of the connecting wire bending device 3... The connecting wire 72 is then bent at a specified angle by tool 34, 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 flat copper wire multi-wound finished product; the flat copper wire windings and connecting wires are all made by bending the same flat copper wire, so the flat copper wire windings of the present invention can be connected and energized without welding, and are produced by corresponding devices, resulting in high production efficiency.

[0037] 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 two adjacent windings, making the structure of the multi-connection flat copper wire winding product of this invention more compact. The vertically bent connecting wire also increases the vertical distance between two 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.

[0038] The flat copper wire multi-wound product of the present invention has multiple windings, and connecting wires are provided between adjacent windings to connect them, eliminating the need to weld adjacent 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 product of the present invention are connected to the power supply, the multiple windings can be energized.

[0039] For example, when there are five windings and four connecting wires, the finished product of this invention 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 mold 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 mold 25, where it is bent into the first connecting wire. The vertical bending mold 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.

[0040] The material-supporting robotic arm device 5 includes a material-supporting bracket, a material-supporting mechanical gripper 51, and a material-supporting space movement component. 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.

[0041] Further, 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, and the flat copper wire coil loading frame 16 is connected to the straightening wheel assembly 13. The flat copper wire loading frame 16 is fixedly connected to the wire outlet 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 wire outlet of the straightening wheel assembly 13. The second clamping assembly 18 is fixedly connected to the straightening bracket 11. The second clamping assembly 18 is spaced apart from the first clamping assembly 17, and the clamping port of the second clamping assembly 18 is aligned with the clamping port of the first clamping assembly 17. In step two, 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.

[0042] The beneficial effects of this technical solution are as follows: 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.

[0043] 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.

[0044] 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.

[0045] The above is a preferred structure of the straightening roller assembly 13. After the flat copper wire from 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The feeding 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. The servo linear motor precisely controls the feeding amount of flat copper wire.

[0050] Both the first clamping assembly 17 and the second clamping assembly 18 are pneumatic grippers. Pneumatic grippers, also known as pneumatic fingers or pneumatic chucks, are actuators that use compressed air as power to clamp or grasp workpieces.

[0051] 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.

[0052] Further, the winding forming device 2 includes a forming bracket 21, a forming slide 22, a horizontal plane bending and adjusting component 23, a winding horizontal plane bending die 24, a connecting wire horizontal plane bending die 25, and a threading tube 26. The forming bracket 21 is fixedly connected to the straightening bracket 11. The forming slide 22 is connected to the forming bracket 21 through the horizontal plane bending and adjusting component 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 component 18. The horizontal plane bending and adjusting component 23 can switch the alignment of the inlet of the winding horizontal plane bending die 24 and the inlet of the connecting wire horizontal plane bending die 25 with the outlet of the threading tube 26. In step three, the horizontal plane bending and adjusting component 23 moves the winding horizontal plane bending die 24 to the outlet of the wire threading tube 26, and the flat copper wire coming out of the wire threading tube 26 is fed into the winding horizontal plane bending die 24. In step four, the horizontal bending and adjusting component 23 causes the winding horizontal bending die 24 to move 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, so that the flat copper wire coming out of the threading tube 26 is transferred to the connecting wire horizontal bending die 25.

[0053] The beneficial effects of this technical solution are as follows: The horizontal bending and adjusting component 23 of the winding forming device 2 changes the position of the forming slide 22, thereby switching the wire inlet of the winding horizontal bending die 24 and the wire inlet of the connecting wire horizontal bending die 25 to the wire outlet of the threading tube 26. With the position of the threading tube 26 unchanged, the winding horizontal bending die 24 and the connecting wire horizontal bending die 25 process the flat copper wire in sequence.

[0054] 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.

[0055] Furthermore, 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, and 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. In step five, the horizontal bending and adjusting component 23 causes the horizontal bending die 25 of the connecting line to leave the outlet of the wire tube 26, and the bending space moving component 32 causes the vertical bending die 34 of the connecting line to contact the connecting line. In step six, when the winding approaches the first lifting and pressing assembly 35, the first lifting and pressing assembly 35 first presses down on the left end of the connecting wire, the second lifting and pressing assembly 36 moves upward away from the right 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 right 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 loading frame 16 to rotate forward simultaneously, rotating the wire guide tube 26 and the flat copper wire forward 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. 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.

[0056] The beneficial effects of this technical solution are as follows: the lifting and pressing assembly of the connecting wire bending device 3 first presses one end of the connecting wire, and the vertical bending die 34 of the connecting wire then 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.

[0057] According to the actual process, the vertical bending die 34 can bend the left end or the right end of the connecting wire by 180°. The winding and the vertical bending die 34 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. 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 the flat copper wire.

[0058] Furthermore, 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. In step three, the lifting motion device 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 adjustment 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 motion device 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 device 246 drives the turntable 241. The limiting block 243 and the bending column 244 cooperate to bend the flat copper wire into the winding.

[0059] The beneficial effects of this technical solution are as follows: the bending column 244 of the horizontal bending die 24 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.

[0060] 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.

[0061] The surface of the conduit 26 is provided with a guide slope 261. 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 slope 261, which helps to complete the subsequent winding action. Also, during the winding process, the bent flat copper wire moves above the right-angle positioning plate.

[0062] One end of the stop block 242 is bolted to the upper side of the limiting block 243, and the other end of the stop block 242 is provided with an arc-shaped opening 2421. The bending column 244 passes through the arc-shaped opening 2421 and is fitted with a clearance. This helps the stop block 242 to better cover the bending channel.

[0063] 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.

[0064] The winding forming device 2 also includes a right-angle positioning plate 27, which is fixedly connected to the forming slide 22 and located above the turntable 241. The wire threading tube 26 abuts against one right-angle side of the right-angle positioning plate 27, and the limiting block 243 abuts against the other right-angle side of the right-angle positioning plate 27. When the position of the forming slide 22 changes, when the wire threading tube 26 abuts against one right-angle side of the right-angle positioning plate 27, the outlet of the wire threading tube 26 is aligned with the inlet of the horizontal bending die 24, 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.

[0065] Furthermore, the winding forming device 2 also includes a wire pressing telescopic component 28 and a wire pressing block 281. The wire pressing block 281 is connected to the forming bracket 21 through the wire pressing telescopic component 28. The forming slide 22 is provided with a clearance groove 221 in the middle. The connecting wire horizontal plane bending mold 25 and the winding horizontal plane bending mold 24 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 wire outlet of the threading tube 26 is located in the rear. The horizontal bending die 25 for connecting lines has the same structure as the horizontal bending die 24 for winding lines. In step four, 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 clearance 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.

[0066] 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.

[0067] 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.

[0068] 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. Its operation differs from that of the horizontal bending die 24 for winding wires. The difference lies in the fact 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°. Then, the turntable rotates 90° clockwise, the limit block returns to its original position, and the threading 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. Then, the turntable rotates 90° clockwise again, and the limit block returns to its original position. At this point, the connecting wire is obtained, and the threading tube stops feeding out the flat copper wire. Here, 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.

[0069] Furthermore, the vertical bending die 34 of 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.

[0070] In step five, the connecting wire is fed between the central bending rod 343 and the eccentric bending rod 344.

[0071] The beneficial effects of this technical solution are: 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 central bending rod 343 and the eccentric bending rod 344 cooperate to bend the connecting line.

[0072] 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.

[0073] Furthermore, the first lifting and pressing assembly 35 includes a first telescopic cylinder 351 and a first pressing plate 352. The cylinder body of the first telescopic cylinder 351 is fixedly connected to the base plate 33, and the telescopic rod of the first telescopic cylinder 351 is fixedly connected to the first pressing plate 352. The second lifting and pressing assembly 36 includes a second telescopic cylinder 361 and a second pressing plate 362. The cylinder body of the second telescopic cylinder 361 is fixedly connected to the base plate 33, and the telescopic rod of the second telescopic cylinder 361 is fixedly connected to the second pressing plate 362. The first pressure plate 352 and the second pressure plate 362 are both located behind the drive shaft 342, and the first pressure plate 352 and the second pressure plate 362 are also located on the left and right sides of the central bending rod 343, respectively. In step six, 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.

[0074] The beneficial effects of this technical solution are: 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 accordingly, ensuring the bending quality.

[0075] 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. The X-axis track 321 is fixedly connected to the bending bracket 31. The X-axis servo slide 322 is slidably connected to the X-axis track 321. The Y-axis track 323 is fixedly connected to the X-axis servo slide 322. The Y-axis servo slide 324 is slidably connected to the Y-axis track 323. The Z-axis track 325 is fixedly connected to the Y-axis servo slide 324. The Z-axis servo slide 326 is slidably connected to the Z-axis track 325. The base plate 33 is fixedly connected to the Z-axis servo slide 326. The position of the corresponding servo slide is controlled by a servo motor and ball screw, using existing technology, to precisely control the spatial position change of the vertical bending die 34 of the connecting line.

[0076] 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. The Z-axis track 325 is fixedly connected to the upper 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.

[0077] Furthermore, 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.

[0078] The beneficial effects of this technical solution are as follows: When the flat copper wire is bent, the wire cutting tool 43 is in its initial position, at which time the wire cutting tool 43 does not interfere with the flat copper wire; after the finished product of this invention is manufactured, the position of the forming slide 22 is adjusted so that the flat copper wire coming out of the wire threading 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 of this invention falls onto the discharge conveyor belt 62 and is finally sent to the receiving frame by the discharge conveyor belt 62.

[0079] 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.

[0080] Furthermore, the horizontal bending die 24 rotates 90° clockwise when bending the flat copper wire and rotates 90° counterclockwise when resetting; the horizontal bending die 25 rotates 90° counterclockwise when bending the flat copper wire and rotates 90° clockwise when resetting; the specified angle is 180°; the set threshold is five.

[0081] Based on the technical concept of an automated production process for multi-unit flat copper wire winding according to the present invention, this embodiment provides a multi-unit flat copper wire winding machine, including: a straightening device 1, a winding forming device 2, a connecting wire bending device 3, a wire cutting device 4, a material-supporting robot device 5, and a PLC control device (not shown). The PLC control device is electrically connected to the straightening device 1, the winding forming device 2, the connecting wire bending device 3, the wire cutting device 4, and the material-supporting robot device 5. The PLC control device is used to control the operating status of the straightening device 1, the winding forming device 2, the connecting wire bending device 3, the wire cutting device 4, and the material-supporting robot device 5 to orderly produce multi-unit flat copper wire winding products. The PLC control device can also be replaced with an industrial computer. It also includes: a frame 6, which is fixedly connected to the straightening support 11, forming support 21, bending support 31, wire cutting support 41, and material support support. The frame 6 is provided with a protective door 61 and a discharge conveyor belt 62. The protective door 61 is provided with a material inlet. One end of the discharge conveyor belt 62 is located between the winding forming device 2 and the connecting wire bending device 3, and is also located below the wire cutting tool 43. The other end of the discharge conveyor belt 62 passes through the material inlet of the protective door 61.

[0082] 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 the invention, according to actual process needs, the horizontal bending die 25 can also be paused. By setting the operating parameters in the PLC control device, the horizontal bending die 24 is selected to make the connecting wire. At this time, the length of the flat copper wire coming out of the wire guide tube 26 is increased, that is, the feed amount of the flat copper wire is set to the feed amount used for processing the connecting wire. The horizontal bending die 24 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 return to the state of processing the winding, and the feed amount of the flat copper wire becomes the feed amount used for processing the winding.

[0083] This invention provides an automated production process for multi-connection winding of flat copper wire, aiming to overcome 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 invention adopts a completely new technical approach to achieve the connection and energization of flat copper wire windings without welding. The overall process involves passing a straightened flat copper wire sequentially 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 multi-connection winding of flat copper wire, and finally the straightened flat copper wire is cut.

[0084] The workflow of this invention is as follows: (1) Flat copper wire coil loading: The flat copper wire coil is installed in the straightening device 1; (2) Flat copper wire straightening: The second clamping assembly 18 clamps the flat copper wire, and after the first clamping assembly 17 releases the flat copper wire, the pulling drive assembly 14 causes the straightening slide 12 to retract. 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, which straighten the bent flat copper wire; (3) Feeding: After the second clamping assembly 18 releases and the first clamping assembly 17 clamps the flat copper wire, the pulling drive assembly 14 causes the straightening slide 12 to move forward, feeding the flat copper wire into the winding forming device 2. 26; (4) First winding: The horizontal bending and adjusting component 23, the 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 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 causes the center bending rod 343 and the eccentric bending rod 344 of the vertical bending mold 34 of the connecting wire to be inserted into the connecting wire according to the signal of the PLC control device, and then the corresponding The lifting and pressing assembly 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 assembly 15 makes the straightening wheel assembly 13, the flat copper wire and the wire tube 26 rotate 180°. During the rotation, the bending space movement assembly 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 assembly 23, the winding horizontal bending mold 24 and the pulling drive assembly 14 cooperate to bend the flat copper wire into the second rectangular winding according to the set action requirements of the PLC control device, while the material support machine 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 folded winding and prevent the winding from tilting and falling over as it is folded 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.

In step five, the horizontal bending and positioning component causes the horizontal bending die of the connecting wire to leave the outlet of the conduit, and the bending space moving component causes the vertical bending die of the connecting wire to contact the connecting wire. In step six, when the winding approaches the first lifting and pressing assembly, the first lifting and pressing assembly first presses down on the left end of the connecting wire, the second lifting and pressing assembly moves upward away from the right end of the connecting wire, the first clamping assembly releases the flat copper wire, and the vertical bending die of the connecting wire then bends the right end of the connecting wire. During the bending process, the spinning drive assembly causes the straightening wheel assembly and the flat copper wire winding loading frame to rotate forward simultaneously, rotating the wire guide tube and the flat copper wire forward by a specified angle. The bending space movement assembly causes the vertical bending die of the connecting wire to move synchronously in space as the angle of the flat copper wire changes. When the winding approaches the second lifting and pressing assembly, the second lifting and pressing assembly first presses down on the right end of the connecting wire, the first lifting and pressing assembly moves upward away from the left end of the connecting wire, the first clamping assembly releases the flat copper wire, and the vertical bending die of the connecting wire then bends the left end of the connecting wire. During the bending process, the spinning drive assembly causes the straightening wheel assembly and the flat copper wire winding frame to rotate in opposite directions simultaneously, rotating the wire guide tube and the flat copper wire in opposite directions by a specified angle. The bending space movement assembly causes the vertical bending die of the connecting wire to move synchronously in space as the angle of the flat copper wire changes.
