The turntable 12 is slidably arranged on the workbench, the bottom of the turntable is provided with the adjusting knob 106, the position of the turntable 12 is adjusted through the adjusting knob 106, the relative position between the pushing assembly 203 and the storage assembly 11 is adjusted, and the pushing assembly 203 of the clamping assembly 20 is ensured to accurately push the magnetic steel sheets to the conveying material channel 202 for conveying. Meanwhile, the pushing assembly 203 and the turntable 12 are arranged on the workbench, the workbench is arranged on the bottom plate through the slide rail structure 103, and the pushing assembly 203 is further ensured to push the magnetic steel sheet into the conveying channel 202 at the relative position of the pushing assembly 203 and the conveying channel 202.

The bottom of the turntable 12 is further provided with a jacking assembly, as shown in fig. 8, the jacking assembly comprises a push rod 105 extending to the bottom of the accommodating groove and a second driving assembly 104 driving the push rod 105 to jack the magnetic steel sheet, the second driving assembly 104 is a telescopic cylinder, the pushing assembly 203 pushes the magnetic steel sheet on the topmost layer of the limiting clip 102 to the conveying material channel 202, then the push rod 105 jacks the magnetic steel sheet in the limiting clip 102, and the pushing assembly 203 pushes the next magnetic steel sheet to the conveying material channel 202. After the magnetic steel sheet of one of the storage assemblies 11 is fed, the next storage assembly 11 is transferred to the clamping assembly 20 through the rotation of the rotary table 12, and then the clamping assembly 20 and the jacking assembly are matched to feed the magnetic steel sheet of the next storage assembly 11.

Further, as shown in fig. 7, fig. 7 is an enlarged view of a portion a in fig. 6, the grabbing assembly 201 includes a rotating cylinder 2011 and an insertion block 2012, an opening for inserting the magnetic steel sheet is formed on an end surface of the insertion block 2012, after the magnetic steel sheet moves and extends out of an end portion of the conveying channel 202, the rotating cylinder 2011 drives the insertion block 2012 to rotate, so that the magnetic steel sheet extending out of the end portion of the conveying channel 202 is inserted into the opening of the insertion block 2012, and then the rotating cylinder 2011 rotates to reset, so that the magnetic steel sheet is turned over to a position below the press-fitting assembly 30, and then the magnetic steel sheet on the insertion block 2012 is transferred to the press-fitting platform 40 through the press-fitting assembly 30 for insertion. The end part of the material conveying channel 202 is provided with the correlation sensor 2013, the side surface of the insert block 2012 is provided with a through hole 2014 through which laser of the correlation sensor 2013 passes, when the magnetic steel sheet is embedded into the insert block 2012, the correlation sensor 2013 senses the magnetic steel sheet and indicates that the magnetic steel sheet is embedded in place, the rotary cylinder 2011 rotates to enable the magnetic steel sheet to be overturned to the press-fitting assembly 30, further, the press-fitting assembly 30 is provided with the displacement sensor 31, when the press-fitting assembly 30 inserts the magnetic steel sheet on the rotor, the pressing displacement of the press-fitting assembly 30 is detected in real time through the displacement sensor 31, the press-fitting position is controlled accurately, and the magnetic steel sheet is guaranteed to be pressed in place and cannot be damaged due to overvoltage.

In summary, in one or more embodiments of this application, this application is through setting up material loading subassembly and centre gripping subassembly, the material loading subassembly includes storage component, be formed with the loading structure that is used for holding not unidimensional magnetic steel piece at storage component, and then realize loading the magnetic steel piece of different model sizes through the loading structure on the storage component, centre gripping subassembly sets up in storage component ejection of compact one side, press from both sides the magnetic steel piece and the upset material loading on the storage component through the centre gripping subassembly, only can be in order to realize assembling the material loading of the magnetic steel piece of different model sizes to the rotor of different batches through storage component when assembling the rotor of different batches, realize the magnetic steel piece material loading of compatible different models, need not dispose polytype material loading revolving stage and material loading anchor clamps, assembly quality is high, greatly improve production efficiency and reduce manufacturing cost.
