[0027] 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.

[0028] like Figures 1 to 4As shown, an automatic piece sorting device for loose pieces of motor cores comprises a frame 100, and a piece sorting unit 200 and a material unloading unit 300 arranged on the frame 100, the piece sorting unit 200 comprises a loading mechanism 21, a first material moving mechanism 22, a bearing mechanism 23 and a second material moving mechanism 24, the loading mechanism comprises a loading line 211, and a carrier 212 arranged on the loading line 211, the carrier 212 is provided with a positioning ring 2121 with side openings 212a on two opposite sides for positioning loose pieces 400, the first material moving mechanism 22 comprises a multi-axis manipulator 221, and a first material moving assembly 222 arranged on the multi-axis manipulator 221, the first material moving assembly 222 comprises a mounting plate 2220, a rotating motor 2221 and a clamping plate 2224, the rotating motor 2221 is arranged on the multi-axis manipulator 221 The output end is provided with a mounting plate 2220 and can drive the mounting plate 2220 to rotate. The mounting plate 2220 is provided with a clamping cylinder 2223. A pair of clamping plates 2224 are arranged at the output end of the clamping cylinder 2223. The pair of clamping plates 2224 are driven to extend into the side opening 212a to clamp the side wall of the loose sheet 400. The supporting mechanism 23 is used to support the loose sheets that are fed multiple times by the first material moving mechanism 22 and stacked to form an iron core 500. The second material moving mechanism 24 is used to move the iron core 500 formed in the supporting mechanism 23 to the unloading unit 300. The unloading unit 300 includes a unloading line 301 and a tray 302 arranged on the unloading line 301. A positioning seat 303 is provided on the tray 302. The positioning seat 303 is used to support the iron core 500 moved from the supporting mechanism 23 by the second material moving mechanism 24.

[0029] The utility model is applied to the post-process of the punching machine after the stamping process of the loose piece 400. After the stamping process, the loose piece 400 is fed to the feeding mechanism 21, specifically, it is placed on the positioning ring 2121 on the carrier 212. The positioning ring 2121 can ensure the stability of the loose piece 400 during the feeding process. The carrier 212 moves on the feeding line 211 to the side close to the bearing mechanism 23. The first material moving component 222 is driven by the multi-axis manipulator 221 to clamp the loose piece 400. Specifically, the rotating motor 2221 and the mounting plate 2220 that play a connecting role drive the clamping plate 2224 to move downward, and the clamping plate 2224 can be matched with the side opening 212a on the positioning ring 2121 through the rotation adjustment of the rotating motor 2221. The clamping plate 2224 continues to move downward, and the clamping cylinder 2223 drives a pair of clamping plates 2224 is translated and embedded into the side opening 212a and abuts against the side wall of the loose piece 400 to clamp it, and then the multi-axis manipulator 221 drives the first material moving assembly 222 and the loose piece 400 to be placed in the supporting mechanism 23. During this process, the rotating motor 2221 can also drive the loose piece 400 to rotate to ensure that it is accurately positioned in the supporting mechanism 23. After the first material moving mechanism 22 is reset, it re-clamps other loose pieces and stacks them on the upper end of the loose pieces in the supporting mechanism 23. This is repeated many times until the number / thickness of the loose pieces reaches the set requirements to form an iron core 500, and then the iron core 500 in the supporting mechanism 23 is moved to the unloading unit 300 through the second material moving mechanism 24, specifically, the iron core 500 is placed on the positioning seat 303 on the tray 302, and is unloaded through the unloading line 301 to the next process to unload the positioning seat 303 and the iron core 500. In order to ensure the accuracy and stability of feeding the iron core 500 into the unloading unit 300, the unloading unit 300 also includes a second lifting assembly 304, which can be composed of a lifting module, and positioning pins, support plates and other components arranged on the lifting module. After the second lifting assembly 304 is moved up (through the cooperation of positioning pins and positioning holes, etc.), it fixes the tray 302 to prevent its translational misalignment, and lifts the positioning seat 303 through the support plate to carry the iron core 500 fed by the second material transfer mechanism 24. Then, the second lifting assembly 304 is reset to drop the positioning seat 303 on the tray 302 and then continue to translate to complete subsequent unloading.

[0030] In the utility model, the loose sheets 400 are stably loaded through the loading line 21, the loose sheets 400 are stably clamped into the supporting mechanism 23 by the first material moving component 222 to be stacked to form the iron core 500, and the iron core 500 is fed to the unloading unit 300 by the second material moving mechanism 24 to complete the unloading, thereby realizing automatic loading and stacking of the loose sheets 400 and automatic unloading of the iron core 500, improving the automation level and efficiency of sheet sorting (forming iron core), and the feeding process and the material moving process are more precise and stable, thereby ensuring the quality of sheet sorting.

[0031] Furthermore, a bottom opening 212b is provided on the carrier 212 at the side opening 212a of the positioning ring 2121, that is, the bottom opening 212b and the side opening 212a form a connecting structure, and a pair of clamps 2224 are provided with a support plate 2225 at the lower end close to each other. The support plate 2225 can extend downward into the bottom opening 212b and abut against the lower end of the loose piece 400 driven by the translational action of the clamp 2224. Therefore, while the clamp 2224 abuts against the side wall of the loose piece 400 for clamping, the support plate 2225 abuts against the lower end of the loose piece 400 to have a supporting effect. The use of the support plate 2225 can further ensure the stability of the loose piece 400 when the first material moving component 222 is feeding, and can prevent the loose piece 400 from falling.

[0032] In addition, a guide slope (not shown) can be set on one side of the support plate 2225 close to each other. The guide slope has a certain giving effect, which can make it easier for the support plate 2225 to extend into the lower end of the loose piece 400 while abutting against the bottom end of the loose piece 400.

[0033] In order to further improve the stability of the loose piece 400 when the first material moving component 222 is feeding, the first material moving component 222 also includes a pressure ring 2227, which is arranged on the mounting plate 2220 through a connecting column 2226 and is located above the support plate 2225. Based on the above arrangement, when the first material moving component 222 clamps the loose piece 400, the pressure ring 2227 first abuts against the upper end of the loose piece 400, and then the clamping cylinder 2223 drives the clamping plate 2224 to abut against the side wall of the loose piece 400, and the support plate 2225 abuts against the bottom end of the loose piece 400, so that the loose piece 400 can be placed in a wrapped state, and the stability of the loose piece 400 can be guaranteed even if the multi-axis manipulator 221 drives the first material moving component 222 to tilt and flip.

[0034] Furthermore, the connecting column 2226 is screwed onto the mounting plate 2220 , and the lower end thereof is rotatably disposed on the pressing ring 2227 . The height of the pressing ring 2227 can be adjusted by rotating the connecting column 2226 , thereby being suitable for loose sheets with different thicknesses.

[0035] like Figure 3As shown, the supporting mechanism 23 includes a first lifting component 231 and a supporting seat 232. The supporting seat 232 is arranged at the output end of the first lifting component 231 to support the scattered pieces fed by the first material moving mechanism 22 for multiple times. The first lifting component 231 may also include a lifting module, which drives the supporting seat 232 to be located at a certain height to receive the scattered pieces. After placing each scattered piece, the lifting module drives the supporting seat 232 to descend to a corresponding height so that the first material moving component 222 can be located at the same height to unload the scattered pieces. In addition, the first lifting component 231 may also include a rotating module, which is arranged at the output end of the lifting module. On the basis of having a lifting function, it can also realize rotation in a horizontal plane to ensure that multiple scattered pieces are overlapped and stacked with their same vertical projections (the upper and lower holes are overlapped).

[0036] In order to ensure that the loose pieces 400 are accurately placed on the supporting seat 232 and the iron core 500 is accurately placed on the positioning seat 302, especially that multiple loose pieces 400 are located on the supporting seat 232 without deviation or rotational displacement from each other, vertical guide rods (not shown) can be provided on the supporting seat 232 and the positioning seat 302, and positioning is achieved by the vertical guide rods cooperating with the corresponding hole structures on the loose pieces 400 or the iron core 500.

[0037] The second material moving mechanism 24 includes a multi-axis module 241 and a second material moving component 242 arranged at the output end of the multi-axis module 241. The multi-axis module 241 can realize movement in three-dimensional space. The second material moving component 242 has a similar structure to the first material moving component 241. The difference is that when the second material moving component 242 also has a pressure ring, it is necessary to adjust the connecting column to make the position of the pressure ring more upward to adapt to the thickness of the iron core 500, so as to ensure the stability of the iron core 500 during material moving.

[0038] In the present invention, the sheet sorting unit 200 may be provided with two loading mechanisms 21, two supporting mechanisms 23 and two second material moving mechanisms 24, which are arranged side by side, so as to improve the loading efficiency of the loose sheets 400 and the unloading efficiency of the iron cores 500, thereby improving the sheet sorting efficiency.

[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
