In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a magnetic ring forming device, including a folding mechanism 1 and a winding mechanism 2. Figure 4 FIG. 2 is a schematic diagram of the structure of the winding mechanism 2. The magnetic ring forming device is used to wind the material strip 100 into a magnetic ring. Figure 5 and Figure 6 shown.

[0051] The folding mechanism 1 is used to fold the corners of the ends of the material strip 100 into a folding structure 101 (see Figure 5 ); see Figure 3 and Figure 4The winding mechanism 2 includes a support frame 21, a forming assembly 22 rotatably disposed on the support frame 21, and a clamping assembly 23 disposed on the forming assembly 22. The clamping assembly 23 is used to clamp the folding structure 101. When the forming assembly 22 rotates, the material strip 100 is wound at least one circle to form a magnetic ring. Further, the magnetic ring forming device also includes a frame 10, the frame 10 includes a frame body below and a workbench above the frame body, and the folding mechanism 1 and the winding device are both disposed on the workbench of the frame 10.

[0052] It should be noted that the above-mentioned at least one circle includes one circle and multiple circles.

[0053] Specifically, during winding, the material strip 100 is first loaded to the position of the folding mechanism 1, and the folding mechanism 1 is actuated to fold a corner of the end of the material strip 100 to form a folding structure 101, such as Figure 5 As shown. The material strip 100 with the angle structure 101 continues to be fed to the position of the winding mechanism 2, and the clamping assembly 23 of the winding mechanism 2 fixes the end of the material strip 100 by clamping the angle structure 101, and then drives the forming assembly 22 to rotate relative to the support frame 21 to wind the material strip 100 one or more circles to form a magnetic ring. Clamping the angle structure 101 by the clamping assembly 23 can ensure the firmness of the end of the material strip 100 during winding, avoid the displacement of the material strip 100 due to traction during winding, improve the positioning accuracy and precision of the magnetic ring during winding and forming, ensure that the formed magnetic ring meets the design requirements, and then ensure the excellent performance of the motor rotor after assembly.

[0054] In this embodiment, the folding mechanism 1 folds a corner of the end of the material strip 100 to 90 degrees, that is, a 90-degree angle is formed between the folding structure 101 and the unfolded material strip 100, so that the clamping assembly 23 is easier to clamp and fix.

[0055] Exemplarily, the material strip 100 is placed perpendicular to the workbench when being loaded, and its thickness direction is horizontal. The folding mechanism 1 includes two clamping blocks for clamping the material strip 100, and the two clamping blocks are respectively arranged on both sides of the material strip 100. The material strip 100 is clamped by the two clamping blocks before folding. It can be understood that the corners on the upper side of the end of the material strip 100 need to be exposed during clamping, and at least one of the two clamping blocks is connected to the cylinder to move and clamp the material strip 100 under the drive of the cylinder. The folding mechanism 1 also includes a folding drive cylinder and a bending member, and the folding drive cylinder is arranged on the frame 10, and the bending member is connected to the output end of the folding drive cylinder. After the two clamping blocks clamp and fix the material strip 100, the folding drive cylinder drives the bending member to move to push the corner position of the material strip 100, thereby bending out the folding structure 101. Furthermore, a forming surface matched with the angle structure 101 is provided on the clamping block, and when the angle structure 101 is pushed and bent until it fits with the forming surface, it is bent into place.

[0056] Exemplarily, the clamping assembly 23 includes a clamping jaw cylinder, whose output end includes at least two clamping jaws, and the two clamping jaws are provided with inclined surfaces adapted to the angle structure 101. After the clamping jaw cylinder is started, the two clamping jaws approach each other, so that the two inclined surfaces approach the two side surfaces of the angle structure 101, until they are respectively clamped on the two side surfaces of the angle structure 101. It can be understood that the angle structure 101 is bent toward the inside of the magnetic ring to avoid affecting the winding of multiple turns of the magnetic ring.

[0057] It should be noted that after the clamping assembly 23 clamps and fixes the angle structure 101 , the end of the material strip 100 is fitted with the molding assembly 22 .

[0058] In this embodiment, the material strip 100 is wound multiple times to form a magnetic ring. Figure 6 As shown, only the schematic diagram after winding two turns is shown.

[0059] In this embodiment, see Figure 1 , Figure 2 as well as Figure 3 The magnetic ring forming device further includes a feeding mechanism 3, which is used to convey the material belt 100 along the extension direction of the material belt 100 and to convey the material belt 100 perpendicular to the workbench. The feeding mechanism 3 realizes the automatic conveying and loading of the material belt 100, thereby improving the automation and intelligence of the magnetic ring forming device.

[0060] Alternatively, see Figure 7 and Figure 8 The feeding mechanism 3 includes a first driving member 31, a driving roller 32 and a driven roller 33. The housing of the first driving member 31 is fixedly mounted on the workbench of the frame 10 through a fixing seat 36, and the output end of the first driving member 31 is transmission-connected with the driving roller 32, and the driving roller 32 is rotatably mounted on the fixing seat 36. The driven roller 33 is parallel to the axis of the driving roller 32, and the material belt 100 is passed through and clamped between the driving roller 32 and the driven roller 33. When feeding, the first driving member 31 drives the driving roller 32 to rotate, and the friction between the driving roller 32 and the material belt 100 drives the material belt 100 to move forward for feeding.

[0061] Exemplarily, the first driving member 31 is a rotary motor.

[0062] Furthermore, the driven roller 33 is used to provide a certain pressure to press the material belt 100 against the driving roller 32, so that there is enough friction between the driving roller 32 and the material belt 100 to smoothly convey the material belt 100.

[0063] For more details, see Figure 7 and Figure 8The feeding mechanism 3 further includes a second driving member 34 and a mounting frame 35. The housing of the second driving member 34 is fixedly mounted on the workbench through a mounting plate, the output end of the second driving member 34 is telescopically arranged in the housing, and the output end of the second driving member 34 is transmission-connected to the mounting frame 35 to drive the mounting frame 35 to move along the radial direction of the driving roller 32, and the driven roller 33 is rotatably arranged on the mounting frame 35. When the second driving member 34 drives the mounting frame 35 to move, the driven roller 33 can approach or move away from the driving roller 32, so that the driven roller 33 can press the material belt 100 with a suitable pressure.

[0064] See also Figure 8 The mounting frame 35 includes a first frame 351, a second frame 352 and an elastic structure 353. The first frame 351 is connected to the output end of the second driving member 34; the driven roller 33 is rotatably mounted on the second frame 352; the elastic structure 353 is connected between the second frame 352 and the first frame 351, and can be elastically retracted along the radial direction of the driving roller 32. When the output end of the second driving member 34 drives the first frame 351 to move toward the driving roller 32, the elastic structure 353 is compressed, so that the driven roller 33 is elastically pressed against the material belt 100, avoiding rigid contact between the driven roller 33 and the material belt 100, and preventing jamming during feeding.

[0065] Exemplarily, the second driving member 34 is a cylinder, and the output end thereof is a telescopic rod of the cylinder.

[0066] Alternatively, see Figure 1 , Figure 2 as well as Figure 3 The magnetic ring forming device also includes a folding mechanism 4, which is used to fold a Z-shaped interlocking structure 102 at a set position of the material strip 100. Figure 6 As shown, the distance between the interlocking structure 102 and the front end face of the material strip 100 is the designed circumference of the innermost circle of the magnetic ring; an interlocking groove 1021 is formed on the inner side of the interlocking structure 102, and the interlocking groove 1021 is interlocked with the front end of the material strip 100, so that the inner wall of the innermost circle of the magnetic ring is a smooth circle. Since the distance between the interlocking structure 102 and the front end face of the material strip 100 is exactly the designed circumference of the innermost circle of the magnetic ring, after the material strip 100 is wound around, the front end is exactly interlocked at the position of the interlocking structure 102, so that the inner wall of the innermost circle of the magnetic ring has no protruding parts, forming a smooth cylindrical inner wall, ensuring good performance of the magnetic ring.

[0067] It can be understood that the distance between the above-mentioned set position and the head of the material strip 100 is exactly the designed circumference of the innermost circle of the magnetic ring.

[0068] Exemplarily, the folding mechanism 4 includes a folding drive cylinder and two folding forming blocks, and the material strip 100 can be transferred between the two folding forming blocks. At least one folding forming block is connected to the folding drive cylinder, and the shell of the folding drive cylinder is fixed on the workbench of the frame 10. For example, the two folding forming blocks are connected to the folding drive cylinder on the side facing away from each other, so that the two folding forming blocks can be close to or away from each other. Both folding forming blocks are provided with a forming structure that is compatible with the above-mentioned interlocking structure 102, and the gap between the two forming structures is consistent with the shape of the interlocking structure 102. When the folding drive cylinder drives the folding forming blocks to approach each other, under the action of the forming structure, the material strip 100 is folded into a Z-shaped interlocking structure 102.

[0069] like Figure 3 and Figure 4 As shown, the winding mechanism 2 also includes a third driving member 24 and a transmission assembly 25. The forming assembly 22 includes a coaxially connected connecting column 221 and a forming turntable 222. The third driving member 24 is connected to the connecting column 221 through the transmission assembly 25. The forming turntable 222 is located at the end of the connecting column 221 away from the transmission assembly 25, and the diameter of the forming turntable 222 is greater than the diameter of the connecting column 221, so that an installation space is formed between the side where the forming turntable 222 is connected to the connecting column 221 and the connecting column 221. The clamping assembly 23 is fixed on the side where the forming turntable 222 is connected to the connecting column 221. The structural arrangement is more reasonable and compact, and it can save materials used in the equipment and reduce equipment costs. The material strip 100 is wound and formed on the forming turntable 222, and its innermost circle is in contact with the outer wall of the forming turntable 222.

[0070] Furthermore, a limiting step surface is provided on the upper ring of the forming turntable 222, and the upper side surface of the material strip 100 is in contact with the limiting step surface so that each circle of the magnetic ring after winding multiple circles is flush.

[0071] Alternatively, see Figure 3 The support frame 21 includes a support platform and a support column disposed below the support platform, and the lower end of the support column is fixedly connected to the workbench. The connecting column 221 and the forming turntable 222 are disposed below the support platform. The transmission assembly 25 is installed above the support platform. The transmission assembly 25 includes a driving pulley 251, a driven pulley 252 and a transmission belt 253. The driving pulley 251 and the driven pulley 252 are both rotatably mounted on the support platform, and the transmission belt 253 is wound around the driving pulley 251 and the driven pulley 252. Figure 4The third driving member 24 is installed on the bottom surface of the supporting platform, and its output end passes through the supporting platform and is connected to the driving pulley 251 for driving the driving pulley 251 to rotate. The driving pulley 251 drives the driven pulley 252 to rotate through the transmission belt 253. The connecting column 221 is connected to the driven pulley 252, so that the driven pulley 252 drives the forming turntable 222 to rotate through the connecting column 221 to wind the material belt 100.

[0072] Exemplarily, the third driving member 24 is a rotary motor. By adjusting the rotation speed and torque of the rotary motor, the winding speed and winding force can be adjusted.

[0073] Optionally, the magnetic ring forming device further comprises a pressing guide mechanism 5, see Figure 5 and Fig. 9 The pressing guide mechanism 5 includes a fourth driving member 51 and a pressing member 52. The output end of the fourth driving member 51 is in transmission connection with the pressing member 52 to drive the pressing member 52 to approach or move away from the forming assembly 22. The pressing member 52 can press against the side of the forming turntable 222 of the material strip 100 that is away from the forming assembly 22, thereby improving the winding forming accuracy of the magnetic ring. Furthermore, the pressing member 52 is elastically pressed against the material strip 100 to avoid hard contact with the material strip 100, and can adaptively retreat when the material strip 100 is wound to avoid the forming space of the magnetic ring. Exemplarily, a guide block is connected to the pressing member 52 through a spring, and the guide block elastically presses against the material strip 100.

[0074] Exemplarily, the fourth driving member 51 is a cylinder.

[0075] Alternatively, see Figure 1 , Figure 3 as well as Fig. 9 The magnetic ring forming equipment also includes a welding mechanism 6 and a clamping mechanism 7, and both the welding mechanism 6 and the clamping mechanism 7 are installed on the workbench of the frame 10. The welding mechanism 6 can be a welding machine. The clamping mechanism 7 can be clamped on the outermost circle of the magnetic ring, and at least the outermost two circles of the magnetic ring are welded and fixed by the welding mechanism 6. The magnetic ring needs to be welded and fixed after winding to prevent the magnetic ring from loosening. During welding, the clamping mechanism 7 is clamped on the outermost circle of the magnetic ring to fix the shape of the magnetic ring. The welding mechanism 6 is welded on at least the outermost two circles of the magnetic ring to prevent the magnetic ring from loosening after winding. For example, the outermost two circles, three circles, four circles, etc. are welded from the outside to the inside, which is selected according to the design requirements.

[0076] See also Fig. 9 The pressing mechanism 7 includes a fifth driving member 71 and a pressing member 72. The housing of the fifth driving member 71 is fixed on the workbench. The pressing member 72 is connected to the output end of the fifth driving member 71. The pressing member 72 moves linearly under the drive of the fifth driving member 71 to press or release the material strip 100. Furthermore, one end of the pressing member 72 close to the material strip 100 is a flexible structure (such as a rubber block, etc.) to avoid crushing the material strip 100.

[0077] Exemplarily, the fifth driving member 71 is a cylinder.

[0078] See also Figure 1 , Figure 2 as well as Figure 3 The magnetic ring forming equipment also includes a cutting mechanism 8, which is used to cut the material strip 100 to form a single magnetic ring, and the cutting point is the front end of the next magnetic ring. Exemplarily, the cutting mechanism 8 includes a sixth driving member and a cutting knife. The shell of the sixth driving member is installed on the workbench, and its output end is connected to the cutting knife to drive the cutting knife to move along the thickness direction of the material strip 100, so as to cut the material strip 100. One cutting knife can be provided, and a cutting fixed block is provided at a position opposite to it. The material strip 100 is located between the cutting knife and the cutting fixed block, and the cutting knife cuts the material strip 100 when it moves. Alternatively, two cutting knives can be provided opposite to each other, and the material strip 100 is located between the two cutting knives.

[0079] Exemplarily, the sixth driving member is a cylinder.

[0080] Alternatively, see Figure 1 and Fig.10 The magnetic ring forming equipment also includes a wiping mechanism 9, which is used to wipe off impurities on the material strip 100 before winding, to ensure the cleanliness of the material strip 100, and to prevent impurities from affecting the performance of the magnetic ring. Exemplarily, the wiping mechanism 9 includes two cleaning brushes arranged opposite to each other, and the material strip 100 is transmitted between the two cleaning brushes and rubbed against the cleaning brushes so that the cleaning brushes wipe and remove dirt on the surfaces of both sides of the material strip 100. Furthermore, the two cleaning brushes are each mounted on a seat body, for example, they are positionally adjustable on the corresponding seat body, so that the distance between the two cleaning brushes can be adjusted to facilitate the application of appropriate cleaning friction. Alternatively, the two cleaning brushes can also be each connected to an output rod of a cylinder to achieve the adjustment of the distance between the two cleaning brushes.

[0081] Alternatively, see Figure 1 A lifting and positioning mechanism 20 is provided under the workbench. The pallet enters from the main conveyor line and stops above the lifting and positioning mechanism 20. Subsequently, the lifting and positioning mechanism 20 positions and lifts the pallet. At this time, the pallet carries the tooling and the magnetic steel sheet completed in the previous process. After the magnetic ring is wound and cut, it can fall into the pallet. The lifting and positioning mechanism 20 then descends and returns the pallet to the main conveyor line for the next process.

[0082] The lifting and positioning mechanism 20 includes a lifting cylinder and a lifting plate. The lifting cylinder is installed on the frame 10. The lifting plate is connected to the output end of the lifting cylinder. Optionally, a positioning column is diagonally arranged on the lifting plate, and a positioning groove is diagonally recessed on the lower end surface of the pallet. The positioning column is inserted into the positioning groove to realize the positioning between the lifting plate and the pallet. After positioning, the lifting plate continues to lift the pallet under the action of the lifting cylinder until it is lifted into place. When descending, the pallet falls on the main conveyor line.

[0083] Optionally, at least one control button 30 is installed on the workbench of the rack 10, and the control button 30 is connected to the control unit of the magnetic ring forming device. After pressing the control button 30, a control instruction is sent to the control unit to implement the corresponding function. For example, the control button 30 includes a power button, a power button, and a pause button. The power button implements the device power-on function, the power button implements the device power-off function, and the pause button implements the device pause function after being pressed, and stops the device in time in an accident or fault state to ensure the safety of the equipment and personnel.

[0084] The magnetic ring forming device provided in this embodiment has the following working process:

[0085] S1. The pallet enters from the main conveyor line and stops above the lifting and positioning mechanism 20. Then, the lifting and positioning mechanism 20 positions and lifts the pallet.

[0094] S81, the pressing member 72 of the pressing mechanism 7 moves forward and extends to press on the outermost circle of the material strip 100;

[0095] S82, the welding mechanism 6 operates to weld the outermost two, three or four circles of the magnetic ring to prevent the magnetic ring from loosening;

[0096] S83 , the pressing member 72 of the pressing mechanism 7 retracts to release the material strip 100 .

[0097] S9, continue winding 150 degrees (this angle is self-adjustable).

[0098] S10, repeat step S8, and weld a second group of welding points at the position directly opposite to the welding mechanism 6.

[0099] S11, the cutting mechanism 8 operates to cut the material strip 100 at the designed length position.

[0100] S12, continue winding for 30 degrees (this angle is self-adjustable).

[0101] S13, repeat step S8, and weld the third group of welding points at the position directly opposite to the welding mechanism 6.

[0102] S14, the pressing member 52 of the pressing guide mechanism 5 retracts to release the material belt 100, and the clamping assembly 23 releases the angle structure 101, so that the welded magnetic ring falls into the tray below; the lifting and positioning mechanism 20 drives the tray to descend, so that the tray falls back onto the main conveyor line.

[0103] S15, looping the above steps S1 to S14, and completing the winding and welding processes of multiple magnetic rings in sequence.

[0104] This embodiment also provides a production system, including a main conveyor line and the magnetic ring forming device as described above. The main conveyor line is used to convey a pallet, which receives the formed magnetic ring under the action of the lifting and positioning mechanism 20 and transports the magnetic ring to the next process position.
