Description

Technical Field

[0001] This invention belongs to the field of motor stator manufacturing technology, specifically relating to an automatic bending and forming equipment for flat copper wire conductors. Background Technology

[0002] The new energy vehicle industry has developed rapidly in recent years, and electric vehicles place high demands on motors. With the development of flat wire technology, electric vehicle motors are gradually adopting flat wire windings. This type of winding can efficiently utilize the space of the motor's stator slots to meet the performance requirements of electric vehicles.

[0003] The production of motor stators involves bending flat copper wire of a certain specification multiple times. Currently, there are various forming methods on the market. Most of them combine the laying, straightening, paint removal, cutting, 2D and 3D forming of flat copper wire into one machine, which makes the equipment process complex. Moreover, due to the mold forming method, only one flat copper wire conductor can be formed at a time, resulting in low efficiency. Its cycle time still cannot meet the growing new energy market, and its stability needs to be improved. In addition, the forming method of this type of forming equipment uses mold forming. During the forming process, each position of the flat copper wire will contact the inner surface of the mold for stamping, which can easily damage the paint of the flat copper wire. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to provide an automatic bending and forming equipment for flat copper wire conductors, which solves the problems of easy damage to the enamel coating and low forming efficiency in the prior art when using molds to form flat copper wire conductors.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] An automatic bending and forming device for flat copper wire conductors includes:

[0007] The feeding mechanism is mounted on the frame and includes an upper tray assembly and a lower tray assembly. The feeding mechanism is driven by a drive assembly to slide for the alternating feeding of flat copper wire conductors.

[0008] The forming mechanism is located on one side of the feeding mechanism, and the forming mechanism includes a primary forming component and a secondary forming component for bending and forming the flat copper wire conductor twice.

[0009] The feeding and gripping mechanism, mounted on the frame, is used to grip the flat copper wire conductor on the feeding mechanism and place it into the forming mechanism to complete the bending and forming.

[0010] By adopting the above structural design, the present invention achieves continuity in the feeding process of flat copper wire conductor forming through the double-layer design of the upper and lower tray components of the feeding mechanism, thereby improving the efficiency of subsequent forming. At the same time, the forming method avoids the problem of paint damage on the surface of the flat copper wire conductor caused by die stamping by bending the primary forming component and the secondary forming component. Furthermore, the forming mechanism can form multiple flat copper wires at one time, and its forming efficiency is far higher than that of die stamping in the prior art.

[0011] As a further improvement, the feeding mechanism also includes a mounting plate fixedly installed on the frame. The mounting plate has two sets of slide rails of different heights on the inner and outer sides. Two conveyor belts are provided between the two sets of slide rails, and the two ends of the conveyor belts are respectively connected to the rotating shafts. One of the rotating shafts is driven to rotate by the forward and reverse rotation of a first drive motor installed on the mounting plate, which drives the conveyor belt to move back and forth. The upper pallet assembly and the lower pallet assembly are slidably mounted on the outer and inner slide rails respectively, and are respectively fixedly connected to the conveyor belts and driven by the conveyor belts.

[0012] With the above structural design, the forward and reverse rotation of the first drive motor drives the rotating shaft to rotate in both directions, thus driving the conveyor belts set at both ends of the rotating shaft to move back and forth. This, in turn, drives the upper pallet assembly and the lower pallet assembly, which are fixedly connected to the conveyor belt, to alternately enter the feeding position to achieve continuous feeding, thereby improving the subsequent forming efficiency.

[0013] As a further improvement, the upper pallet assembly includes an upper sliding plate and an upper hopper fixedly mounted on the upper sliding plate, with both ends of the upper hopper slidably mounted on outer slide rails; the lower pallet assembly includes a lower sliding plate slidably mounted on an inner slide rail, and a first movable hole is provided in the middle of the lower sliding plate; a lifting mechanism is fixedly mounted on the lower surface of the lower sliding plate, and the upper end of the lifting mechanism passes through the first movable hole and is fixedly connected to the lower hopper provided above; a second movable hole is provided vertically through the middle of the mounting plate, allowing the lifting mechanism of the lower pallet assembly to move back and forth; both ends of the upper and lower sliding plates are provided with fixing plates for fixed connection with the upper and lower layers of the conveyor belt, respectively.

[0014] With the above structural design, the upper pallet assembly and the lower pallet assembly have a height difference, and this height difference is sufficient to prevent interference during their mutual movement. However, due to the height inconsistency, during the feeding process, it is necessary to adjust the height of the two to be consistent in order to ensure that the feeding mechanism can grasp them smoothly. Therefore, this application provides a lifting mechanism below the lower pallet assembly. After the lower pallet assembly enters the grasping position, the lifting mechanism lifts the lower hopper to a position flush with the upper hopper to facilitate the grasping of the flat copper wire conductor.

[0015] As a further improvement, the upper and lower silos have the same structure and are each provided with several receiving slots for stacking and loading flat copper wire conductors.

[0016] With the above structural design, in order to cooperate with the forming mechanism to form multiple conductors at one time, the upper and lower material bins are respectively provided with several receiving slots, and the depth of the receiving slots can accommodate multiple flat copper wire conductors, thereby improving the efficiency of feeding and forming.

[0017] As a further improvement, the feeding and gripping mechanism includes a four-axis robot fixedly mounted on the frame and a gripping component mounted on the four-axis robot;

[0018] The gripping assembly includes a gripping frame movably connected to a four-axis robot. Two lateral adjustment cylinders and two longitudinal adjustment cylinders are respectively provided at both ends of the gripping frame. The lateral adjustment cylinders are fixedly installed at both ends of the gripping frame and are fixedly connected to a slider provided on the other side of the gripping frame, which can drive the slider to move laterally. The lower end of the slider is connected to a claw for gripping the flat copper wire conductor and fixing both ends of the flat copper wire conductor by the lateral movement of the slider. The longitudinal adjustment cylinders are fixedly installed on the slider and located above the claw for fixing the flat copper wire conductor from above.

[0019] By adopting the above structural design, the two ends of the flat copper wire conductor are fixed by the horizontal adjustment cylinder of the gripping component, and the upper end of the flat copper wire conductor is fixed by the vertical adjustment cylinder. This ensures that multiple flat copper wire conductors can be gripped at one time to complete the feeding, thus improving the feeding efficiency.

[0020] As a further improvement, the lateral adjustment cylinder and the longitudinal adjustment cylinder are respectively arranged on both sides of the gripping frame. A third movable hole is opened at one end of the gripping frame. The first connecting block on the lateral adjustment cylinder installed at this end is fixedly connected to the slider. A second connecting block is arranged on the lateral adjustment cylinder at the other end of the gripping frame. The second connecting block is provided with a connecting shaft that is connected to the slider on the other side. The connection between the connecting shaft and the second connecting block is elastically connected by a spring. When fixing the end of the flat copper wire conductor, it can be applied to flat copper wire conductors of different sizes.

[0021] With the above structural design, a spring is provided at the connection between the connecting shaft and the second connecting block. Therefore, when gripping and fixing flat copper wire conductors, the elasticity of the spring makes it applicable to gripping and fixing flat copper wire conductors of different sizes, thus making it more versatile.

[0022] As a further improvement, the claw has a gripping groove extending downwards on its inner side, and a pad extending to the middle of the gripping groove is provided on the lower end face to support the flat copper wire conductor. The lower end of the longitudinal adjustment cylinder is connected to a pressure block, which is located directly above the gripping groove. The end of the pressure block has a tapered structure to facilitate entering the gripping groove to fix the flat copper wire conductor.

[0023] With the above structural design, the gripping slot can effectively fix multiple flat copper wire conductors at once, resulting in greater stability and preventing conductors from detaching or being accidentally gripped or released.

[0024] As a further improvement, the molding mechanism also includes a mounting frame fixedly installed on the frame, and the primary molding component and the secondary molding component are movably mounted on the mounting frame;

[0025] The secondary forming assembly includes two forming units symmetrically arranged on the mounting frame. Each forming unit includes a second rotating plate pivotally mounted on the mounting frame. A second drive motor is provided on one side of the second rotating plate, and meshing teeth are provided on the edge of the second rotating plate. The second drive motor drives the second rotating plate to rotate by meshing with the meshing teeth of the second rotating plate through a gear connected to its end. Mounting brackets are fixedly mounted on the second rotating plate for mounting the primary forming assembly. The secondary forming assembly also includes a secondary bending unit, which is arranged on the mounting frame and located at the center of the primary forming assembly and the secondary forming assembly. The end of the secondary bending unit is provided with a secondary bending pin.

[0026] The one-time molding assembly includes two molding units symmetrically arranged on the mounting frame. Each molding unit includes a fixed plate slidably mounted on the mounting frame. A third drive motor is fixedly mounted on the lower end of the fixed plate, and a first rotating plate is pivotally mounted on the upper end. The side edge of the first rotating plate is provided with meshing teeth. The gear connected above the fixed plate at the end of the third drive motor meshes with the meshing teeth of the first rotating plate and drives it to rotate. The upper end of the first rotating plate is also provided with multiple clamping seats. The outer clamping seats are provided with clamping grooves, and the inner clamping seats are provided with a bending pin.

[0027] By employing the above structural design, the forming structure cleverly combines a primary forming component and a secondary forming component. Position adjustment is achieved via a motor-driven rotating plate, allowing the held flat copper wire conductors to bend at the primary and secondary bending pins as support points. Multiple flat copper wire conductors can be bent simultaneously in a single operation, resulting in higher bending efficiency. Furthermore, the bending forming method prevents the coating from peeling off the flat copper wire conductors. The primary and secondary forming components can adjust the rotation angle of the drive motor according to the bending angle of the flat copper wire conductors, thus enhancing versatility.

[0028] As a further improvement, the clamping groove is equipped with a movable clamping block, which is driven by a clamping cylinder located behind the clamping seat. The clamping block ensures that multiple flat copper wire conductors will not deviate when bent and formed simultaneously, thereby ensuring the forming quality of the flat copper wire conductors.

[0029] As a further improvement, the upper end of the mounting frame is provided with a displacement adjustment slide rail, and the fixing plate of the one-time forming component is provided with a corresponding adjustment slide groove. The one-time forming component is slidably mounted on the mounting frame through the fixing plate, and a servo module is installed on the mounting frame and connected to the fixing plate to adjust the displacement of the one-time forming component to accommodate flat copper wire conductors with different bending spans.

[0030] With the above structural design, since the spacing between the two legs of the U-shaped structure of different flat copper wire conductors is not the same, the interval between the two forming units of the one-time forming component can be adjusted by the servo module to suit different models of products, thus making it more versatile.

[0031] As a further improvement, the automatic bending and forming equipment for flat copper wire conductors also includes a feeding mechanism, which is set on one side of the forming mechanism for gripping and feeding the bent and formed flat copper wire conductors into the next process; the feeding mechanism includes a robotic arm and a gripping unit mounted on the robotic arm. The gripping unit includes a connecting plate connected to the robotic arm, and the connecting plate is provided with two finger cylinders to drive the gripping fingers to grip and transfer the formed flat copper wire conductors.

[0032] With the above structural design, the feeding mechanism can quickly clamp and fix the two legs of the formed conductor and transfer it to the next process through the two finger cylinders. It is efficient and stable.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. This invention achieves continuous feeding during the forming and feeding of flat copper wire conductors through the double-layer design of the upper and lower tray components of the feeding mechanism, thereby improving the cycle time of subsequent forming. At the same time, the forming method avoids the problem of paint damage on the surface of the flat copper wire conductor caused by die stamping by using a primary forming component and a secondary forming component for bending forming. Furthermore, the forming mechanism can form 6 flat copper wires at a time, and its forming cycle time is much higher than that of die stamping forming in the prior art.

[0035] 2. The gripping component of the present invention uses a horizontal adjustment cylinder to fix both ends of the flat copper wire conductor and a vertical adjustment cylinder to fix the upper end of the flat copper wire conductor, thereby ensuring stable gripping of multiple flat copper wire conductors at one time to complete the feeding, thus improving the feeding efficiency; and the connection between the connecting shaft and the second connecting block is elastically connected by a spring, which can be applied to flat copper wire conductors of different sizes when fixing the ends of the flat copper wire conductors, thus making it more versatile.

[0036] 3. The forming mechanism of this invention cleverly combines a primary forming component and a secondary forming component, and uses a motor-driven rotating plate to achieve position adjustment. This allows the clamped flat copper wire conductors to be bent at the primary and secondary bending pins, respectively, using these pins as support points. Furthermore, multiple clamped flat copper wire conductors can be bent and formed simultaneously in one operation, resulting in higher bending efficiency. The primary and secondary forming components also allow for adjustment of the drive motor's rotation angle according to the bending angle of the flat copper wire conductors, thus enhancing versatility.

[0037] 4. The one-time molding component of the present invention is slidably mounted on the mounting frame of the two-time molding component through a fixed plate, and a servo module is installed on the mounting frame to adjust the interval between the two molding units of the one-time molding component to adapt to the bending span of different models of products. Therefore, the equipment has greater versatility. Attached Figure Description

Detailed Implementation

[0053] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0054] Please see Figures 1 to 13 An automatic bending and forming equipment for flat copper wire conductors includes a frame 1 and a feeding mechanism 2, a feeding gripping mechanism 4, a forming mechanism 3, and a discharging mechanism 5 mounted on the frame 1.

[0055] The frame 1 is equipped with a protective cover (not shown in the figure), which mainly serves to isolate personnel from the internal structure of the equipment, preventing personnel from coming into contact with the internal structure during equipment operation and causing injury. It is also equipped with multiple doors for easy maintenance and repair. The protective cover is also equipped with a rotating operation screen 11 for human-machine interaction, and a three-color light 12 to convey the corresponding status of the equipment.

[0056] Please see Figure 2 , Figure 3 and Figure 4 The feeding mechanism 2 is mounted on the frame 1 and includes an upper tray assembly 21 and a lower tray assembly 22. The feeding mechanism 2 is driven by the drive assembly 23 to slide for the alternating feeding of flat copper wire conductors 100.

[0057] Specifically, the feeding mechanism 2 further includes a mounting plate 29 fixedly installed on the frame 1. The mounting plate 29 has two sets of slide rails 24 of different heights on its inner and outer sides. Multiple fixed seats 291 are provided at the lower end of the mounting plate 29 and are fixedly connected to the frame 1. In this embodiment, the height difference between the two upper pallet assemblies 21 and lower pallet assemblies 22 ensures that they do not interfere with each other when moving alternately up and down. Two conveyor belts 25 are provided between the two sets of slide rails 24, and both ends of the conveyor belts 25 are connected to a rotating shaft 26. One rotating shaft 26 is driven to rotate by the forward and reverse rotation of a first drive motor 27 mounted on the mounting plate 29, causing the conveyor belt 25 to reciprocate. Specifically, the rotating shaft 26 is connected to the first drive motor 27 via a connecting belt (not shown in the figure) to drive the rotating shaft 26 to rotate. The upper pallet assembly 21 and lower pallet assembly 22 are slidably mounted on the outer and inner slide rails 24, respectively, and are fixedly connected to the conveyor belts 25 and driven by the conveyor belts 25. The drive assembly 23 consists of the conveyor belt 25, the rotating shaft 26, and the first drive motor 27.

[0058] The upper pallet assembly 21 includes an upper slide plate 211 and an upper hopper 212 fixedly mounted on the upper slide plate 211. Both ends of the upper slide plate 211 are slidably mounted on the outer slide rail 24. The lower pallet assembly 22 includes a lower slide plate 221 slidably mounted on the inner slide rail 24. A first movable hole (not shown) is provided in the middle of the lower slide plate 221. A lifting mechanism 222 is fixedly mounted on the lower surface of the lower slide plate 221. The upper end of the lifting mechanism 222 passes through the first movable hole and is fixedly connected to the lower hopper 223 provided above. A second movable hole 292 is provided vertically through the middle of the mounting plate 29, allowing the lifting mechanism 222 of the lower pallet assembly 22 to move back and forth. Fixed pressure plates 28 are provided at both ends of the upper slide plate 211 and the lower slide plate 221 for fixed connection with the upper and lower layers of the conveyor belt 25, respectively. In this invention, the upper pallet 211 is fixed to the upper layer of the conveyor belt 25, and the lower pallet 221 is fixed to the lower layer of the conveyor belt 25, thereby achieving the height difference between the upper pallet assembly 21 and the lower pallet assembly 22. The initial positions of the upper pallet assembly 21 and the lower pallet assembly 22 are located at opposite ends of the conveyor belt 25. The first drive motor 27, in both forward and reverse rotation, enables the conveyor belt 25 to reciprocate, thereby driving the upper pallet assembly 21 and the lower pallet assembly 22 to alternately reciprocate. During material loading, one assembly can load material while the other loads it, ensuring loading efficiency and continuity, and effectively guaranteeing subsequent molding. In this embodiment, the upper hopper 212 and the lower hopper 223 have the same structure and are each provided with several receiving slots 2121 and 2231 for stacking and loading flat copper wire conductors 100. The upper hopper 212 has 36 accommodating slots 2121, and each accommodating slot 2121 can hold 18 layers of stacked materials. Therefore, each upper hopper 212 or lower hopper 223 can hold 648 flat copper wire conductors 100.

[0059] Please see Figures 8 to 11 The feeding and gripping mechanism 4 is mounted on the frame 1 and is used to grip the flat copper wire conductor 100 on the feeding mechanism 2 and place it into the forming mechanism 3 to complete the bending and forming. The feeding and gripping mechanism 4 includes a four-axis robot 41 fixedly mounted on the frame 1 and a gripping component 42 mounted on the four-axis robot 41.

[0060] The gripping assembly 42 includes a gripping frame 421 movably connected to a four-axis robot 41. Two lateral adjustment cylinders 422 and two longitudinal adjustment cylinders 423 are respectively provided at both ends of the gripping frame 421. The lateral adjustment cylinders 422 are fixedly mounted at both ends of the gripping frame 421 and are fixedly connected to a slider 424 provided on the other side of the gripping frame 421, driving the slider 424 to move laterally. A gripper 425 is connected to the lower end of the slider 424 for gripping the flat copper wire conductor 100 and fixing both ends of the flat copper wire conductor 100 by the lateral movement of the slider 424. The longitudinal adjustment cylinders 423 are fixedly mounted on the slider 424 and located above the gripper 425 for fixing the flat copper wire conductor 100 from above.

[0061] The lateral adjustment cylinder 422 and the longitudinal adjustment cylinder 423 are respectively disposed on both sides of the gripping frame 421. One end of the gripping frame 421 is provided with a third movable hole 4211. The first connecting block 4221 on the lateral adjustment cylinder 422 installed at this end is fixedly connected to the slider 424. The other end of the gripping frame 421 is provided with a second connecting block 426 on the lateral adjustment cylinder 422. The second connecting block 426 is provided with a connecting shaft 427 connected to the slider 424 on the other side. The connection between the connecting shaft 427 and the second connecting block 426 is elastically connected by a spring 428. When fixing the end of the flat copper wire conductor 100, it can be applied to flat copper wire conductors 100 of different sizes.

[0062] The gripper 425 has a downward-pointing gripping groove 4251 on its inner side, and a pad 4252 extending to the middle of the gripping groove 4251 to support the flat copper wire conductor 100 on its lower end. A pressure block 429 is connected to the lower end of the longitudinal adjusting cylinder 423, and the pressure block 429 is located directly above the gripping groove 4251. The end of the pressure block 429 has a tapered structure to facilitate entry into the gripping groove 4251 to fix the flat copper wire conductor 100. In this embodiment, the gripping groove 4251 can grip 18 flat copper wire conductors 100 at a time and transfer them to the forming mechanism 3, resulting in high gripping efficiency.

[0063] Please see Figure 5 , Figure 6 and Figure 7 The forming mechanism 3 is located on one side of the feeding mechanism 2, and the forming mechanism 3 includes a primary forming component 31 and a secondary forming component 32 for bending and forming the flat copper wire conductor 100 twice.

[0064] The molding mechanism 3 further includes a mounting frame 33 fixedly mounted on the frame 1, and the primary molding component 31 and the secondary molding component 32 are movably mounted on the mounting frame 33. The secondary molding component 32 includes two molding units (not shown) symmetrically arranged on the mounting frame 33. Each molding unit includes a second rotating plate 321 pivotally mounted on the mounting frame 33. Specifically, the mounting frame 33 is provided with an arc-shaped rotating slide rail 331, and the lower end of the second rotating plate 321 is provided with a rotating groove (not shown). The two second rotating plates 321 of the two molding units are pivotally mounted on the mounting frame 33 at one apex. A second drive motor 322 is provided on one side of each second rotating plate 321. The edge of the second rotating plate 321 is provided with meshing teeth. The second drive motor 322 drives the second rotating plate 321 to rotate by meshing with the meshing teeth of the second rotating plate 321 through a gear connected to its end. The second rotating plate 321 is fixedly equipped with mounting brackets 323 for the installation of the primary forming component 31. The secondary forming component 32 also includes a secondary bending unit, which is set on the mounting frame 33 and located at the center of the primary forming component 31 and the secondary forming component 32. The end of the secondary bending unit is provided with a secondary bending pin 324, which serves as a support point for bending.

[0065] The one-time molding assembly 31 includes two molding units symmetrically arranged on the mounting frame 323. Each molding unit includes a fixed plate 311 slidably mounted on the mounting frame 323. A third drive motor 312 is fixedly mounted on the lower end of the fixed plate 311, and a first rotating plate 313 is pivotally mounted on the upper end. The side edge of the first rotating plate 313 is provided with meshing teeth. The gear connected above the fixed plate 311 at the end of the third drive motor 312 meshes with the meshing teeth of the first rotating plate 313 and drives it to rotate. The upper end of the first rotating plate 313 is also provided with multiple clamping seats 314. In this embodiment, each first rotating plate 313 is provided with two clamping seats 314. The outer clamping seat 314 is provided with a clamping groove 315, and the inner clamping seat 314 is provided with a one-time bending pin 316. The clamping groove 315 is provided with a movable clamping block 317, and the clamping block 317 is driven by a clamping cylinder 318 provided behind the clamping seat 314.

[0066] The upper end of the mounting bracket 323 is provided with a displacement adjustment slide rail 3231, and the fixing plate 311 of the one-time forming component 31 is correspondingly provided with an adjustment slide groove. The one-time forming component 31 is slidably mounted on the mounting bracket 323 via the fixing plate 311, and a servo module 319 is mounted on the mounting bracket 323 and connected to the fixing plate 311. This servo module is used to adjust the displacement of the one-time forming component 31 to accommodate flat copper wire conductors 100 with different bending spans. The servo module 319 is an existing standard part and will not be described in detail here. Since the distance between the two legs of the U-shaped structure of different flat copper wire conductors 100 is inconsistent, the distance between the two forming units of the one-time forming component can be adjusted by the displacement adjustment cylinder mentioned above to accommodate different models of products.

[0067] The bending angle can be determined or adjusted according to the rotation parameters of the second drive motor 322 and the third drive motor 312, and can be applied to bending at different angles. In the initial position, the secondary bending pin 324, the primary bending pin 316 and the clamping groove 315 are located on the same horizontal straight line, which ensures the smooth feeding of the flat copper wire conductor 100. Moreover, the clamping groove 315 can simultaneously stack 6 flat copper wire conductors 100 for one-time forming, and the forming cycle is 6 times that of mold forming.

[0068] Please see Figure 12 and Figure 13 The unloading mechanism 5, located on one side of the forming mechanism 3, is used to grip and unload the bent and formed flat copper wire conductor 100 into the next process. The unloading mechanism 5 includes a robotic arm 51 and a gripping unit 52 mounted on the robotic arm 51. The gripping unit 52 includes a connecting plate 521 connected to the robotic arm 51. Two finger cylinders 522 on the connecting plate 521 drive gripping fingers 523 to grip and transfer the formed flat copper wire conductor 100. In this embodiment, one finger cylinder 522 is arranged horizontally and the other vertically, thus ensuring that the formed flat copper wire conductor 100 is gripped and fixed from different directions, guaranteeing gripping stability.

[0069] Working principle of the invention:

[0070] When it is necessary to perform 2D forming on the flat copper wire conductor 100, firstly, the straight flat copper wire conductor 100 is installed on the upper hopper 212 and the lower hopper 223 of the feeding mechanism 2, and 18 layers are placed in each receiving slot 2121, and 648 flat copper wire conductors 100 can be placed in each hopper. The first drive motor 27 drives the conveyor belt 25 to move the upper hopper 212 and the lower hopper 223 alternately to the loading position through forward and reverse rotation. The loading gripping mechanism 4 then grips and loads the materials. After the upper hopper 212 is loaded, the conveyor belt 25 moves the upper hopper 212 back to its initial position for loading. At this time, the lower hopper 223 enters the loading position. The lifting mechanism 222 lifts the lower hopper 223 to the same level as the upper hopper 212 and continues to grip the materials through the loading gripping mechanism 4. After loading is completed, the lifting mechanism 222 lowers the lower hopper 223 to its initial height, and the conveyor belt 25 drives it back to the loading position to continue loading. Meanwhile, the upper hopper 223, having completed loading, continues to be loaded. By alternating loading, the continuity of loading is ensured.

[0071] When the upper hopper 212 or the lower hopper 223 enters the feeding position, all the horizontal adjustment cylinders 422 and the vertical adjustment cylinders 423 retract, and the gripping component 42 is in the open state. The feeding gripping mechanism 4 adjusts the gripping position through the four-axis robot 41. At this time, the copper wire conductor 100 enters the gripping slot 4251, and 18 copper wire conductors 100 in one accommodating slot can be gripped at one time. Then, the horizontal adjustment cylinder 422 adjusts the position to clamp the two ends of the 18 copper wire conductors 100, while the vertical adjustment cylinder 423 fixes them from above. Then, the copper wire conductors are transferred to the clamping groove 315 of the forming structure 3 and fixed by the clamping block 317. Each time, 6 copper wire conductors 100 can be clamped. Then, all the horizontal adjustment cylinders 422 and vertical adjustment cylinders 423 of the feeding gripping mechanism 4 retract, and the four-axis robot 41 rises to the height of 6 copper wire conductors 100. The horizontal adjustment cylinders 422 open again to fix the remaining 12 copper wire conductors 100. The remaining 12 copper wire conductors 100 are gripped and placed in the waiting position. At this time, the forming mechanism 3 bends and shapes the fixed 6 copper wire conductors 100. The above actions are repeated until all 18 copper wire conductors 100 are consumed. The four-axis robot 41 moves to the feeding position again to repeat the action.

[0072] After the six copper wire conductors 100 are fixed in the clamping groove 315 of the forming mechanism 3, the third drive motor 312 of the primary forming component 31 drives the first rotating plate 313 to rotate. At this time, the six copper wire conductors 100 are bent using the symmetrically arranged primary bending pins 316 as fulcrums to form a U-shaped structure. Then the secondary forming component 32 continues to work. Similarly, the two symmetrically arranged second drive motors 322 drive the two second rotating plates 321 and drive the primary forming component 31, which holds the flat copper wire conductors 100, to rotate together and complete the secondary forming using the secondary bending pins 324 as fulcrums. After forming, the two ends are gripped and fixed by the two finger cylinders 522 of the gripping unit 52 and transferred to the next process.
