[0009] By adopting the above technical scheme, the stacked silicon steel sheets are placed in the feeding conveying mechanism for conveying, and the feeding conveying mechanism conveys the stacked silicon steel sheets to the feeding weighing mechanism for weighing operation. When the weighing operation is completed, the transfer device transfers the silicon steel sheets in the feeding weighing mechanism to the riveting device, thereby completing the feeding operation. During the feeding process, the stacked silicon steel sheets are weighed, so that the produced rotor core is stabilized at a specified weight, which is beneficial to improving the production quality of the rotor core.

[0011] By adopting the above technical scheme, the weighing frame supports the weighing roller and the weighing sensor. When the stacked silicon steel sheets are conveyed to one end of the feeding conveying mechanism close to the riveting device, the conveying inertia transfers the stacked silicon steel sheets to the weighing roller. The weighing roller is rotatably connected to the weighing frame to ensure that the silicon steel sheets are completely separated from the feeding conveying mechanism, which is beneficial to improve the accuracy of the weighing sensor when measuring the weight of the silicon steel sheets. When the weight measured by the weighing sensor is within the weight range, the rotor core is a good product. When the weight measured by the weighing sensor is not within the weight range, the rotor core is a defective product, which is convenient for the subsequent removal of defective products, thereby helping to improve the production quality of the rotor core.

The positioning mechanism is close to the feeding device and is used for angular positioning of the silicon steel sheet. The riveting mechanism is located between the positioning mechanism and the detection mechanism and is used for riveting the silicon steel sheet. The detection mechanism is close to the coding device and is used for performing a through-gauge detection on the silicon steel sheet after the riveting operation is completed.

[0013] By adopting the above technical scheme, when the silicon steel sheets after the weighing operation are transferred to the riveting device, the silicon steel sheets are first transferred to the positioning mechanism, and the positioning mechanism performs angular positioning on the silicon steel sheets, which is beneficial to improving the accuracy of the riveting operation.

Then the rotor core is transferred to the detection mechanism, and the detection mechanism performs a through-gauge detection on the rotor core, which is beneficial to improving the production quality of the rotor core. The spacing between the positioning mechanism, the riveting mechanism and the detection mechanism is the same, so that the transfer device can regularly perform transfer operations on the rotor core, and the transfer operations of each process can be carried out simultaneously, which is beneficial to improving the production efficiency of the rotor core.

[0014] Preferably, the positioning mechanism includes a positioning frame, a positioning seat, a light source, a camera and a rotating drive component. The positioning frame is arranged on the side of the weighing frame away from the feeding and conveying mechanism.

[0017] By adopting the above technical solution, the support seat supports the support plate, the pressure seat and the riveting drive component. When the transfer device transfers the positioned silicon steel sheet to the support plate, the riveting drive component drives the pressure seat to move vertically downward so that the pressure seat performs riveting operations on the silicon steel sheet. During the riveting process, since the support plate can move vertically up and down, the riveting distance of the pressure seat is increased, thereby increasing the riveting strength, and the support plate moves vertically downward to buffer the riveting operation. While increasing the riveting strength, it is beneficial to prevent the riveting impact force from being too large and causing collision damage to the silicon steel sheet.

[0022] Preferably, the detection seat is provided with a through gauge assembly for detecting the passability of the groove teeth, the through gauge assembly includes a through gauge block and a through gauge driving member, the through gauge block is vertically movably arranged in the detection seat, and the through gauge driving member is arranged at the bottom of the detection seat to drive the through gauge block to move vertically up and down.

[0023] By adopting the above technical solution, when the clamping seat clamps the rotor core, the through gauge driving member drives the through gauge block to move vertically upward. If the through gauge block can be inserted into the hole slot of the rotor core, it is a good product. If the through gauge block cannot be inserted into the hole slot of the rotor core, it is a defective product, which is beneficial to improving the production quality of the rotor core.

[0024] Preferably, the coding device includes a coding machine, two clamping plates, a connecting block, a clamping drive and a flipping drive.

[0038] Reference Figure 1 and Figure 2 The feeding device 1 includes a feeding conveying mechanism 11 and a feeding weighing mechanism 12. The feeding weighing mechanism 12 is arranged at the end of the feeding conveying mechanism 11 close to the riveting mechanism. The feeding conveying mechanism 11 is used to convey the stacked silicon steel sheets to the feeding weighing mechanism 12 for weighing operation. When the weighing operation is completed, the transfer device transfers the silicon steel sheets in the feeding weighing mechanism 12 to the riveting device 2. It should be noted that the weight requirement of the rotor core of the new energy motor is high, and weight measurement of the rotor core is conducive to improving the production quality of the rotor core.

Specifically, the riveting device 2 includes a positioning mechanism 21, a riveting mechanism 22 and a detection mechanism 23. The positioning mechanism 21, the riveting mechanism 22 and the detection mechanism 23 are arranged in a straight line in sequence, and the spacing is the same. The spacing between the positioning mechanism 21, the riveting mechanism 22 and the detection mechanism 23 is the same as the spacing between the feeding device 1, the riveting device 2, the coding device 3 and the unloading device 4, so that the chuck 7 can simultaneously complete the transfer operation between the feeding weighing mechanism 12 and the positioning mechanism 21, the transfer operation between the positioning mechanism 21 and the riveting mechanism 22, and the transfer operation between the riveting mechanism 22 and the detection mechanism 23.

[0043] Reference Figure 1 and Figure 3 The positioning mechanism 21 is close to the feeding device 1 and is used for angular positioning of the silicon steel sheet. Specifically, the positioning mechanism 21 includes a positioning frame 211, a positioning seat 212, a light source 213, a camera 214 and a rotating drive. The positioning frame 211 is arranged on the side of the weighing frame 121 away from the feeding conveying frame 111. The positioning seat 212 is horizontally rotated and arranged on the positioning frame 211 to receive the silicon steel sheet. The light source 213 is fixedly arranged on the positioning frame 211 and is aligned with the silicon steel sheet located on the positioning seat 212. In this embodiment, the light source 213 is located directly above the positioning seat 212 and is arranged in a circular ring shape. The camera 214 is fixedly arranged on the positioning frame 211, and the camera 214 is located directly above the light source 213 and passes through the circular hole of the light source 213 to take pictures and detect the silicon steel sheet located on the positioning seat 212. It should be noted that the camera 214 is electrically connected to the rotating drive, and the rotating drive is arranged at the bottom of the positioning frame 211 to drive the positioning seat 212 to rotate horizontally. In this embodiment, the rotating driving member is configured as a rotating motor 215, which is configured vertically upward. The output shaft of the rotating motor 215 is fixedly connected to the positioning seat 212. When the camera 214 takes a photo to detect that the angle of the silicon steel sheet is inaccurate, the camera 214 transmits the information to the rotating motor 215, and the rotating motor 215 drives the positioning seat 212 to rotate horizontally accordingly, so that the positioning seat 212 drives the silicon steel sheet to rotate to the correct angle, which is beneficial to improve the accuracy of subsequent riveting operations.

[0044] Reference Figure 1 and Figure 3 The riveting mechanism 22 is located between the positioning mechanism 21 and the detection mechanism 23 and is used for performing riveting operations on the silicon steel sheets. Specifically, the riveting mechanism 22 includes a support seat 221, a support plate 222, a pressure seat 223 and a riveting driving member. The support seat 221 is arranged on the side of the positioning frame 211 away from the weighing frame 121 to support the support plate 222, the pressure seat 223 and the riveting driving member. The support plate 222 is arranged on the support seat 221 and can move vertically up and down. The pressure seat 223 is located directly above the support plate 222. A riveting block is fixedly arranged on the bottom surface of the pressure seat 223. There is a space for placing the silicon steel sheet between the pressure seat 223 and the support plate 222. The riveting driving member is arranged on the support seat 221 to drive the pressure seat 223 to move vertically up and down. In this embodiment, the riveting driving member is set as a hydraulic cylinder 224. When the transfer device transfers the stacked silicon steel sheets to the support plate 222, the hydraulic cylinder 224 drives the press seat 223 to move vertically downward, so that the rivet block on the press seat 223 impacts and rivets the silicon steel sheets, and the rivet position of the silicon steel sheets is recessed downward to connect the stacked silicon steel sheets together to form the rotor core. It should be noted that the vertical up and down movement of the support plate 222 increases the rivet stroke to ensure that the stacked silicon steel sheets are connected together to form the rotor core.

[0045] Reference Figure 3 A connecting column 5 is vertically arranged at the bottom of the support plate 222, and the connecting column 5 is movably arranged in the support seat 221. At the same time, an elastic member is arranged inside the support seat 221, and the elastic member is located directly below the connecting column 5. In this embodiment, the elastic member is configured as a spring. When the support plate 222 moves vertically downward, the spring is compressed for buffering. While ensuring that the stacked silicon steel sheets are connected together to form the rotor core, the impact force can be reduced to prevent the silicon steel sheets from causing collision damage.

[0046] Reference Figure 1 and Figure 3 The detection mechanism 23 is close to the coding device 3 and is used to perform a through-gauge detection on the silicon steel sheet after the riveting operation is completed, so as to improve the production quality of the rotor core. Specifically, the detection mechanism 23 includes a detection seat 231, a clamping seat 232, a displacement sensor 233 and a detection driver.

The detection driver is arranged on the detection seat 231 to drive the detection component to move vertically up and down. In this embodiment, the detection driver is set to a detection drive cylinder 234. The detection drive cylinder 234 is vertically fixed on the detection seat 231, and the clamping seat 232 is horizontally fixed on the piston rod of the detection drive cylinder 234. At the same time, the clamping seat 232 is provided with an avoidance hole 8 at the hole slot position corresponding to the rotor core. When the transfer device transfers the rotor core to the detection seat 231, the detection drive cylinder 234 drives the clamping seat 232 to move vertically downward so that the clamping seat 232 presses the rotor core. Then the displacement sensor 233 is inserted into the hole slot of the rotor core through the avoidance hole 8 for detection to determine whether there is any displacement between the silicon steel sheets in the rotor core after the riveting operation.

[0047] Reference Figure 3 , the detection seat 231 is provided with a through gauge assembly 6 for detecting the passability of the slot teeth of the rotor core. Specifically, the through gauge assembly 6 includes a through gauge block 61 and a through gauge driving member. The through gauge block 61 is vertically movably arranged in the detection seat 231, and the through gauge driving member is arranged at the bottom of the detection seat 231 to drive the through gauge block 61 to move vertically up and down. In this embodiment, the through gauge driving member is set as a through gauge driving cylinder 62, and the through gauge driving cylinder 62 is vertically arranged. The through gauge block 61 is fixedly connected to the piston rod of the through gauge driving cylinder 62. It should be noted that in the process of inserting the displacement sensor 233 into the hole slot of the rotor core through the avoidance through hole 8 for detection, the upper surface of the through gauge block 61 is flush with the upper surface of the detection seat 231. When the detection operation of the displacement sensor 233 is completed, the through gauge driving cylinder 62 drives the through gauge block 61 to move vertically upward to determine the passability of the slot teeth of the rotor core.

[0048] Reference Figure 4 The coding device 3 includes a coding machine 31, two clamping plates 32, a connecting block 33, a clamping drive and a flipping drive. The two clamping plates 32 are arranged in parallel up and down, and there is a space for accommodating the rotor core between the two clamping plates 32. The clamping drive is arranged on the connecting block 33 to drive the two clamping plates 32 to move in a direction close to or away from each other. The flipping drive is arranged on the coding machine 31 to drive the connecting block 33 to flip 180°. In this embodiment, the clamping drive is set as a bidirectional cylinder 34, and the flipping drive is set as a rotating cylinder 35. The two clamping plates 32 are respectively fixedly connected to the two piston rods of the bidirectional cylinder 34. The stretching and contraction of the two piston rods can realize the movement of the two clamping plates 32 in a direction away from or close to each other. The rotating cylinder 35 drives the connecting block 33 to rotate, so as to realize the flipping operation of the two clamping plates 32 driven by the connecting block 33. At the same time, both clamping plates 32 are provided with a clearance hole 9 for making way for the coding operation, and the coding machine 31 performs coding operations on the front and back sides of the rotor core through the clearance hole 9.

[0049] Reference Figure 1 , the unloading device 4 unloads the rotor core and distinguishes good products from defective products. Specifically, the unloading device 4 includes a good product unloading mechanism 41, a defective product unloading mechanism 42, a pushing cylinder 43 and a pushing plate 44. The good product unloading mechanism 41 is arranged at the rear of the coding machine 31 to receive the rotor core after the coding operation, and the conveying direction of the good product unloading mechanism 41 is the same as the conveying direction of the loading and conveying mechanism 11. The defective product unloading mechanism 42 is arranged on one side of the good product unloading mechanism 41, and the conveying direction of the defective product unloading mechanism 42 is perpendicular to the conveying direction of the good product unloading mechanism 41. The structures of the good product unloading mechanism 41 and the defective product unloading mechanism 42 are the same as the structures of the loading and conveying mechanism 11, which will not be described in detail here. The pushing cylinder 43 is horizontally fixedly arranged in the good product unloading mechanism 41 and is directly opposite to the defective product unloading mechanism 42. Referring to Figure 2 and Figure 3 The push cylinder 43 is electrically connected to the weighing sensor 123 and the displacement sensor 233, and the push plate 44 is vertically fixedly connected to the piston rod of the push cylinder 43. When the detection data of the weighing sensor 123 and the displacement sensor 233 are up to standard, the piston rod of the push cylinder 43 contracts to allow the good rotor core to be transported and unloaded in the good unloading mechanism 41. When as long as one of the detection data of the weighing sensor 123 and the displacement sensor 233 does not meet the standard, the piston rod of the push cylinder 43 stretches to push the defective rotor core into the defective unloading mechanism 42 through the push plate 44 for transportation and unloading, so as to improve the production quality of the rotor core.

[0050] The implementation principle of the integrated processing equipment for the rotor core of a new energy motor in the embodiment of the present application is as follows: the feeding conveying mechanism 11 conveys the stacked silicon steel sheets to the weighing roller 122, the weighing sensor 123 detects the weight of the silicon steel sheets, the chuck 7 transfers the weighed silicon steel sheets to the positioning seat 212, and the camera 214 takes pictures of the silicon steel sheets on the positioning seat 212 through the circular hole of the light source 213. When the angular direction of the silicon steel sheets is detected to be inaccurate, the camera 214 transmits the information to the rotating motor 215, and the rotating motor 215 drives the positioning seat 212 to perform water The chuck 7 transfers the silicon steel sheet after the positioning to the support plate 222, and the hydraulic cylinder 224 drives the pressing seat 223 to move vertically downward, so that the rivet block on the pressing seat 223 impacts and rivets the silicon steel sheet. The riveting position of the silicon steel sheet is concave downward so that the stacked silicon steel sheets are connected together to form a rotor core. The chuck 7 transfers the rotor core after the riveting operation to the detection seat 231, and the detection drive cylinder 234 drives the clamping seat 232 to move vertically downward so that the clamping seat 232 presses the rotor core. The rear displacement sensor 233 is inserted into the hole slot of the rotor core through the avoidance through hole 8 for detection to determine whether there is any displacement between the silicon steel sheets in the rotor core after the riveting operation. Then the through gauge driving cylinder 62 drives the through gauge block 61 to move vertically upward to determine the passability of the rotor core slot teeth. The chuck 7 transfers the rotor core after the inspection to between the two clamping plates 32. The two clamping plates 32 clamp the rotor core under the drive of the two-way cylinder 34, and the rotor core can be turned 180° by the rotating cylinder 35. The coding machine 31 codes the rotor core on both sides through the avoidance hole 9. The chuck 7 transfers the rotor core after the coding operation to the good product unloading mechanism 41 for transportation. When the detection data of the weighing sensor 123 and the displacement sensor 233 are up to standard, the piston rod of the push cylinder 43 contracts to allow the good product rotor core to be transported and unloaded in the good product unloading mechanism 41. When any one of the detection data of the weighing sensor 123 and the displacement sensor 233 is not up to standard, the piston rod of the push cylinder 43 stretches to push the defective rotor core into the defective product unloading mechanism 42 through the push plate 44 for transportation and unloading, so as to improve the production quality of the rotor core. In the entire production process of the rotor core, there is no need for manual transfer, the degree of automation is high, and the operation continuity is strong, which is conducive to improving the production efficiency of the rotor core and reducing labor costs.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
