[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1 to 6 As shown, an automatic production line for motor rotors includes a machine 1, and a processing unit 2 and a blanking unit 3 arranged in an upper shell 11 of the machine 1. The two processing units 2 arranged side by side can perform processing at the same time to improve production efficiency. The processing unit 2 includes a loading device 21, a material moving device 22, an angle adjustment device 23, a chain plate conveyor line 24, a pressurized height measuring device 25, a marking device 26 and a blanking line 27. The loading device 21 includes a loading line 211, a first camera 212 and a lifting mechanism 213. The lifting mechanism The mechanism 213 is arranged below the feeding line 211 and can pass through the feeding line 211 upward to lift the rotor 100. The first camera 212 is used to take pictures to detect the front and back of the rotor 100. The material transfer device 22 is arranged beside the feeding device 21 to clamp the rotor 100 lifted by the lifting mechanism 213, and when the front and back of the rotor 100 are incorrect, the front and back state of the rotor 100 can be adjusted by flipping the action. The angle adjustment device 23 is arranged beside the feeding device 22 and adjusts the front and back state of the rotor 100 from the top through the material transfer device 22. The rotor 100 fed by the feeding device 21 rotates horizontally, and then the material transfer device 22 removes the rotor 100 again and places it on the starting end of the chain plate conveyor line 24. The chain plate conveyor line 24 includes a chain plate line 241, a carrier plate 242 and a positioning tool. The chain plate line 241 is set on the machine 1 and extends along the processing direction. A plurality of carrier plates 242 are fixed on the chain plate line 241 for carrying the rotor 100 fed from the angle adjustment device 23 by the material transfer device 22 and then circulating the material. The positioning tool can be used when the rotor needs to be processed. The rotor is positioned at the work station to ensure that the position of the rotor is accurate and stable. The pressure height measuring device 25 and the marking device 26 are sequentially arranged on the machine 1 for pressure height measurement and laser marking of the rotor fed to its processing station via the chain conveyor line 24. The unloading line 27 in each processing unit 2 cooperates with the unloading unit 3 to unload the completed rotor. The unloading unit 3 can use a conventional three-axis moving mechanism and a clamping mechanism combination to clamp the product from the end of the chain line 24 and then move it to the unloading line 27.

[0035] In the present invention, the rotor 100 is loaded from the loading line 211. When the rotor 100 is fed to the end thereof by the loading line 211, the lifting mechanism 213 lifts the rotor 100 and separates it from the loading line 211. The first camera 212 identifies the state of the rotor 100. If the front and back of the rotor 100 are correct, the material transfer device 22 clamps the rotor 100 and directly transfers the material to the angle adjustment device 23. If the front and back of the rotor 100 are incorrect, the material transfer device 22 clamps the rotor 100 and then flips the rotor 100 before transferring the material to the angle adjustment device 23. The angle adjustment device 23 is used to place the rotor 100 on the angle adjustment device 23 in a uniform state. The angle adjustment device 23 ensures that the state of the rotor is consistent by horizontal rotation. The specific method can be as follows: the angle adjustment device is provided with a support platform, an adjustment mechanism, and a second camera for detecting the rotor angle. The adjustment mechanism is arranged below the support platform. When the rotor 100 fed by the material transfer device 22 is placed on the support platform, the second camera takes a picture of the state of the rotor 100. If the rotor 100 deviates in angle, the adjustment mechanism passes upward through the support platform to lift the rotor 100 and drive the rotor 100 to rotate the corresponding angle in the horizontal plane to ensure that the state of the rotor 100 is accurate. After the adjustment is completed, the rotor 100 is clamped by the material transfer device 22 and fed to the supporting plate 242 on the chain plate conveyor line 24. The supporting plate 242 is driven by the chain plate line 241 to move to the processing station of the pressurized height measuring device 25. After the positioning tool positions the supporting plate 242, the pressurized height measuring device 25 performs pressurized height measurement on the rotor 100. This processing station is completed After processing, the carrier plate 242 is driven by the chain plate line 241 to move to the processing station of the marking device 26. Another positioning tool positions the carrier plate 242, and then the marking device 26 marks the rotor 100. After the processing is completed at this processing station, the carrier plate 242 is driven by the chain plate line 241 to move to the next processing station. In this way, the rotor after processing is located on the carrier plate 242 and is positioned by the positioning tool. The rotor 100 is moved to the unloading line 27 through the unloading unit 3, and the rotor 100 is unloaded from the processing unit 2.

[0036] The present invention performs front and back detection and adjustment, angle detection and adjustment on the rotor 100 through the cooperation of the loading device 21, the moving device 22 and the angle adjustment device 23, and realizes the rotor flipping to complete the front and back adjustment during the moving process, ensuring that the rotor enters the processing process in the correct state, improving the loading efficiency of the rotor 100 during the loading process, and ensuring the loading accuracy, which is convenient for the subsequent process to accurately process the rotor; by setting up a chain plate conveyor line 24 to connect multiple processing stations (pressurized height measuring device 25, marking device 26, etc.) in series, rather than a robot or other device to transfer and position the rotor one by one, the stability and accuracy of the rotor 100 when it is fed to each processing station can be guaranteed. The chain plate conveyor line 24 ensures the feeding efficiency and feeding accuracy of the rotor 100 during the processing, which is convenient for accurate processing of the rotor.

[0037] Continue as Figure 3 As shown, the feeding line 211 is also provided with a height limiting mechanism 214, which includes a lifting adjustment plate 2141 and a height limiting plate 2142. The lifting adjustment plate 2141 is arranged on the machine 1, and the height limiting plate 2142 is arranged on the lifting adjustment plate 2141 and is located above the feeding line 211. By adjusting the position of the height limiting plate 2142 on the lifting adjustment plate 2141, the distance between the bottom end of the height limiting plate 2142 and the feeding line 211 can be limited so that products that exceed the height (the number of silicon steel sheets exceeds the required number, resulting in the height of the product not meeting the standard) cannot pass through; in addition, a stop block 215 is provided at the end of the feeding line 211, and the rotor 100 is blocked by the stop block 215 and then the product is lifted by the lifting mechanism 213.

[0038] The specific structure of the material transfer device 22 includes a moving module and a material transfer tool 221. The moving module can be a conventional two-axis or three-axis moving mechanism. The material transfer tool 221 is set at the output end of the moving module to clamp and flip the rotor 100. Figure 5 As shown, the material transfer tooling 221 includes a connecting plate 2211, a clamping cylinder 2212, a rotating cylinder 2213, and a clamping plate 2214. The connecting plate 2211 is arranged at the output end of the moving module. The clamping cylinder 2212 has a pair of symmetrically arranged on the connecting plate 2211. A pair of rotating cylinders 2213 are respectively arranged at the output end of the clamping cylinder 2212, and the output end is provided with a clamping plate 2214 for clamping the rotor. The pair of clamping cylinders 2212 drive the rotating cylinder 2213 and the clamping plate 2214 located on the rotating cylinder 2213 to clamp the side wall of the rotor 100. The pair of rotating cylinders 2213 then drive the clamping plate 2214 and the rotor 100 to flip to achieve the rotor front and back adjustment function. It should be noted that the lower portion of the connecting plate 2211 has at least a clearance groove or clearance hole 2210 to provide space for the rotor 100 to flip.

[0039] Preferably, the clamping plate 2214 can be selected as a sponge plate with adsorption holes to avoid damage to the outer wall of the rotor 100. The sponge plate forms a negative pressure effect by connecting to an external air source to adsorb the rotor 100 to a certain extent, and ensures the stability of the clamping of the rotor 100 through the clamping effect and adsorption effect.

[0040] In addition, the angle adjustment device 23 may also be configured with a multifunctional structure, such as providing a corresponding weighing device and a support platform, or connecting with an adjustment mechanism to weigh the rotor.

[0041] like Figure 6As shown, the specific structure of the positioning tooling located next to the chain line 241 is as follows: it includes a support module 2431, a downward pressure cylinder 2432 and a pressure plate 2433. The support module 2431 has a lifting function. It is arranged at the lower end of the chain line 241 and is driven to lift the supporting plate 242. The downward pressure cylinder 2432 is arranged on the machine 1. The pressure plate 2433 is arranged at the output end of the downward pressure cylinder 2422 and is driven to press the supported module to lift the supporting plate 242, which can ensure the accurate position of the supporting plate 242 and the rotor 100.

[0042] In addition, the motor rotor production line also includes a cleaning device 28 and a detection device 29, which are sequentially arranged at the rear end of the marking device 26. The machine 1 is also provided with a positioning tool that cooperates with the chain plate line 241 at the above two processing stations; the cleaning device 28 is equipped with an ion wind rod + compressed air + vacuum cleaner, and a booster pump + air storage tank. The rotor 100 rotates during the ion air shower, and adopts an upper blowing and lower suction structure. A protective cover is also provided at the processing station to prevent the blown dust from overflowing. The detection device 29 detects burrs in the magnetic steel slot of the rotor 100 by taking pictures with a CCD camera. By connecting the pressurized height measuring device 25, the marking device 26, the cleaning device 28 and the detection device 29 in series, efficient processing of the rotor can be achieved.
