Detailed Description of the Invention

[0036] The following will specifically describe the present invention in detail with reference to the drawings and embodiments.

[0037] Please refer to Figures 1-4As shown in the figure, the present invention provides a high-speed servo stator and rotor feeding stamping production line, including an uncoiling mechanism 1, an induction gantry 2, a leveling machine 3, an S-shaped buffer area 4, a feeding mechanism 5, a stamping mechanism 6, a pulling machine 7, a servo cutting machine 8 and a PLC control system. A material rack 11 for installing a material tape is arranged on the uncoiling mechanism 1. The material tape passes through the induction gantry 2, the leveling machine 3, the S-shaped buffer area 4, the feeding mechanism 5, the stamping mechanism 6, the pulling machine 7 and the servo cutting machine 8 in sequence from the uncoiling mechanism 1. The induction gantry 2 is used to detect the conveying speed of the material tape and send the detection information to the PLC control system. The leveling machine 3 is used to level the material tape. The feeding mechanism 5 is used to clamp the material tape for feeding. The stamping mechanism 6 is used to stamp the material tape. The remaining material tape is recycled after being shredded by the servo cutting machine 8.

[0038] Further, in order to enable the induction gantry 2 to adjust the speed of the uncoiling mechanism 1 for feeding, the induction gantry 2 is provided with a grating sensor 21 for sensing the conveying speed of the material tape. A horizontally arranged material tape placing conveyor belt 22 is arranged on the bottom surface of the induction gantry 2. The material tape is horizontally placed on the material tape placing conveyor belt 22. The grating sensor 21 is arranged facing the material tape. The material tape placing conveyor belt is provided with rollers arranged side by side. The material tape moves along the material tape placing conveyor belt 22 towards the leveling machine 3. The induction gantry 2 can accurately detect the passing speed of the material tape, and adjust the release speed of the power motor of the uncoiling machine through the PLC control system, avoiding material tape accumulation, and the speed matching accuracy reaches ±0.5%.

[0039] Further, the uncoiling mechanism 1 is provided with a double-head material rack 11. The double-head material rack 11 is respectively driven by a power motor to rotate for uncoiling and feeding. The uncoiling mechanism 1 is also provided with a rotation driving device. The rotation driving device is used to drive the double-head material rack 11 to rotate and turn around for material change. The power motor and the rotation driving device are electrically connected to the PLC control system.

[0040] During installation, the power motors at both ends of the double-head material rack 11 pre-install the coil materials synchronously, and the PLC system monitors the coil diameter in real time;

[0041] When the main coil material is exhausted, the rotation driving device completes a 180° flip and switch within 3 seconds, and the spare coil material can be seamlessly docked with the running material tape through laser welding.

[0042] Further, in order to adjust the alignment of the material rack 11 with the leveling machine 3, the uncoiling mechanism 1 is also provided with a material rack 11 transverse movement mechanism. The material rack transverse movement mechanism is used to drive the material rack 11 to automatically center with the entrance of the leveling machine 3.

[0043] Furthermore, the leveling machine 3 and the S-shaped buffer area 4 are integrally installed on the leveling frame 31. An arc-shaped feeding frame 32 is provided at the lower end of the leveling frame 31. The front end of the feeding frame 32 is arranged opposite to the induction gantry 2. The end of the feeding frame 32 is connected to the input end of the leveling machine 3. The leveling machine 3 is installed in an inclined manner at the lower end position of the leveling frame 31. The output end of the leveling machine 3 is connected to the input end of the S-shaped buffer area 4. The output end of the S-shaped buffer area 4 is arranged opposite to the input end of the feeding mechanism 5. The leveling machine 3 is installed in an inclined manner to utilize gravity to assist in guiding the material tape. Cooperating with the arc-shaped feeding frame 32, it reduces the friction damage of the material tape.

[0044] Furthermore, the S-shaped buffer area 4 includes a plurality of arc-shaped guide plates 41. An S-shaped material passing channel is formed between the arc-shaped guide plates 41. The material passing channel is used for the material tape to pass through. And a horizontal pressing plate 42 is provided at the upper end of the S-shaped buffer area 4. The horizontal pressing plate 42 is used to guide the material tape so that the material tape is output in the horizontal direction. The output end of the S-shaped buffer area 4 is arranged opposite to the input end of the feeding mechanism 5.

[0045] The horizontal pressing plate 42 exerts a vertical pressure on the output material tape to eliminate the warping of the material tape.

[0046] A servo rotary device 9 is further provided in the working area of the stamping die in the stamping mechanism 6. The servo rotary device 9 is used to eliminate the phenomenon of inconsistent thickness generated after the stator and rotor stacked punching sheets. After each punching, the servo rotary device 9 drives the punching sheet to rotate a certain angle. The punching sheets processed subsequently are stacked on the rotated punching sheet, so that the thickness of the stacked punching sheets with uneven thickness can be evenly distributed to eliminate the problem of inconsistent product thickness. And when the servo rotary device 9 adopted in this application is used to produce the motor rotor, after the servo rotary device 9 rotates a set angle and stacks, a motor rotor with a twisted shape can be formed, thereby eliminating the influence of the rotor magnetic poles.

[0047] Furthermore, in another Embodiment 2, as Figure 2As shown in the figure, the stamping mechanism 6 includes a stator stamping machine 61 and a rotor stamping machine 62. The material pulling machine 7 includes a first material pulling machine 71 and a second material pulling machine 72. The feeding mechanism 5 includes a first high-speed servo feeder 51 and a second high-speed servo feeder 52. The first high-speed servo feeder 51 is installed on one side of the stator stamping machine 61. On the other side of the stator stamping machine 61 away from the first high-speed servo feeder 51, there is also a first material pulling machine 71. The material tape is input from the first high-speed servo feeder 51 and output along the first material pulling machine 71. The second high-speed servo feeder 52 is installed on one side of the rotor stamping machine 62. The output end of the first material pulling machine 71 is set facing the input end of the second high-speed servo feeder 52. On the other side of the rotor stamping machine 62 away from the second high-speed servo feeder 52, there is a second material pulling machine 72 installed. The output end of the second material pulling machine 72 is connected to the servo cutting machine 8. The two feeders can use driving rollers of different widths, so as to ensure that the feed rollers of the second feeding device can completely cover the diameter of the blank holes generated by the first stamping.

[0048] The stator stamping machine 61 and the rotor stamping machine 62 are also provided with a finished product discharge conveyor belt. A visual inspection unit can also be provided at the finished product discharge conveyor belt to scan the dimensions of the stamped parts in real time, and the data is fed back to the PLC control system to dynamically adjust the die position.

[0049] Adopt a push / pull feeding system to ensure that the longer material tape maintains a constant tension when passing through the stamping die. The stator stamping machine 61 and the rotor stamping machine 62 respectively stamp and form the stator and the rotor. The double-servo coordinated feeding and stamping make the production efficiency higher during continuous production.

[0050] The servo cutting machine 8 cuts up the remaining material tape and recycles the shredded materials.

[0051] A production process of a high-speed servo stator-rotor feeding and stamping production line includes the following steps:

[0052] S1. Uncoiling and blanking: Load the silicon steel coil raw material into the material rack 11. Through the cross-moving mechanism of the material rack 11 provided by the uncoiling mechanism 1, align the product on the material rack 11 with the inlet direction of the leveling machine 3. Start the power motor to drive the material tape to rotate and release for blanking.

[0053] S2. Gantry detection and speed regulation: The material tape passes through the material tape placement conveyor belt 22 provided by the induction gantry 2. The grating sensor 21 provided on the induction gantry 2 detects the conveying speed of the material tape, sends the detection information to the PLC control system, and the PLC control system controls the power motor to adjust the speed to ensure that the conveying speed of the material tape matches the requirements of the downstream process.

[0054] S3. Material tape leveling: The material tape enters the leveling machine 3 along the feed rack 32 provided at the front end of the leveling machine frame 31. Start the rollers of the leveling machine 3 to extrude and level the material tape.

[0055] S4. Tape buffering: After being leveled by the leveling machine 3, the tape enters the S-shaped buffer area 4, and the tape is temporarily stored through the S-shaped buffer area 4.

[0056] S5. Automatic feeding: The tape is provided with conveying power by the high-speed servo feeder set on one side of the stamping machine. The feeding roller of the high-speed servo feeder clamps the tape and conveys it towards the stamping machine.

[0057] S6. Stamping and forming processing: The tape enters the stamping machine, and the stamping machine die performs punching processing on the tape. The processed and formed products are output by the finished product discharge conveyor belt.

[0058] S7. Scrap recycling: The remaining tape after stamping is pulled by the tape pulling machine set on the other side of the stamping machine, and then cut by the servo cutting machine 8 to recycle the waste scraps.

[0059] In this application, the leveling machine 3 and the S-shaped buffer area 4 are integrally installed on the leveling machine frame 31. The S-shaped buffer area 4 can greatly reduce the floor area of the buffer area in the traditional stamping production line, with higher space utilization rate. And the set buffer area improves the production stability and die life significantly by absorbing shock, optimizing logistics, and enhancing the forming quality.

[0060] In this application, a double-head material rack 11 is provided in the uncoiling mechanism 1, which can hold two coils at the same time. When one coil is used up, only by turning around can the coil be quickly changed, reducing the downtime and improving the production efficiency.

[0061] The induction gantry 2 set in this application can accurately detect the passing speed of the tape, and adjust the release speed of the power motor of the uncoiling machine through the PLC control system to avoid tape accumulation.

[0062] In this application, a feeder and a tape pulling machine are respectively installed on both sides of the stamping machine. The feeder and the tape pulling machine pull the tape one after the other, and the coordinated operation of the feeding rollers ensures that the tape maintains a constant tension when passing through the die.

[0063] In another embodiment, this application can also be provided with two stamping machines, namely a stator stamping machine 61 and a rotor stamping machine 62. The feeding mechanism 5 includes a first high-speed servo feeder 51 and a second high-speed servo feeder 52. Compared with a single punching press equipment, the double-feed system has higher production efficiency, lower cost, and lower manual operation intensity than the single punching press operation, and is suitable for mass production.
