[0038] Outer fixed disc 202 is annularly arranged on the top of turntable 201, as shown in the figure, outer fixed disc 202 has six, so as to realize the consistency of rhythm. Plug rod 204 is annularly arranged on the top of outer fixed disc 202, the cross-sectional size of plug rod 204 is matched with the size of wire slot of inner side wall of stator sheet, so that stator sheet is inserted on plug rod 204.

[0039] Guide part 205 is obliquely arranged on the top of plug rod 204, the wire slot in stator sheet is guided through guide part 205, so as to play the positioning role of stator sheet, when transfer assembly 3 clamps stator sheet, the position accuracy during clamping is improved.

[0040] Inner lifting disc 203 is arranged in outer fixed disc 202, and through groove is formed in inner lifting disc 203 and matched with plug rod 204, one is to avoid the position of plug rod 204, and the other is that when inner lifting disc 203 is lifted to lift stator sheet, the stability of lifting movement of inner lifting disc 203 and the accuracy of lifting position are improved through the limiting of plug rod 204 to inner lifting disc 203, so as to improve the accuracy of transfer assembly 3 sucking the uppermost stator sheet of inner lifting disc 203.

[0041] Inner lifting disc 203 and outer fixed disc 202 are not fixed together, but are inserted together, so that under the jacking action of jacking cylinder 207, inner lifting disc 203 will be lifted together with the stator sheet above, facilitating the clamping of transfer assembly 3.

[0042] The stator sheet is inserted on the inserting rod 204 and abuts against the upper surface of the inner lifting disc 203, which is used to drag the multiple layers of stator sheets. The inserting rod 204 has two functions: one is to guide and position the inserted stator sheet; the other is to limit the lifting movement of the inner lifting disc 203 and the stator sheet, so as to avoid the deviation of the inner lifting disc 203 and the stator sheet during lifting.

[0043] The cylinder body of the jacking cylinder 207 is fixed on the rack 1, and the piston rod of the jacking cylinder 207 is connected with the jacking block 208. The jacking block 208 is driven upward by the jacking cylinder 207, and then the inner lifting disc 203 is lifted upward by the jacking block 208, so as to lift the stator sheet. The transfer assembly 3 sucks the uppermost stator sheet of the inner lifting disc 203, and the inner lifting disc 203 is lifted by the jacking cylinder 207 to the height of the thickness of the stator sheet.

[0044] When the stator sheet is inserted on the inserting rod 204, the shape of the stator sheet can be flexibly changed according to the needs of the customer. For example, six outer fixed discs 202 are arranged on the rotating disc 201, and the A type stator sheet can be inserted on each outer fixed disc 202. The A type stator sheet can also be inserted on one of the outer fixed discs 202, and the B type stator sheet can be inserted on another outer fixed disc 202, so as to realize the diversity of stator assembly.

[0045] As shown in Figure 5 、 6 , it is a structure schematic view of the transfer assembly 3. The transfer assembly 3 is used to suck the uppermost stator sheet of the inner lifting disc 203. The transfer assembly 3 includes a transfer frame 301, a linear sliding table 302, a transfer plate 303, a transfer mechanism, a lifting sliding table 310, a second lifting plate 311, a separation disc 312, a separation air block 313, an air groove 314, a dipping frame 315, a dipping disc 316 and a dipping sponge 317. The transfer frame 301 is fixed on the rack 1 by screw fastening and located on one side of the rotating disc 201.

[0046] The linear sliding table 302 is fixed on one side of the transfer frame 301, and the transfer plate 303 is connected with the linear sliding table 302. The transfer plate 303 is moved by the linear sliding table 302, and then the transfer work of the stator sheet is completed. The transfer mechanism is two, which is fixed at intervals on one side of the transfer plate 303 away from the transfer frame 301. Each transfer mechanism includes a lifting cylinder 304, a first lifting plate 305, an air plate 306, a pressing plate 307, an air hole 308 and an avoiding hole 309. The lifting cylinder 304 is fixed on one side of the transfer plate 303 away from the transfer frame 301, and the first lifting plate 305 is connected with the lifting cylinder 304. The first lifting plate 305 is lifted by the lifting cylinder 304.

[0047] As shown in Figure 7 、 8As shown, the air plate 306 is fixed at the bottom of the first lifting plate 305, and a plurality of suction nozzles are arranged on the air plate 306 for sucking a stator sheet on the uppermost layer of the inner lifting disc 203. The pressing plate 307 is fixed at the bottom of the air plate 306, and Figure 9 As shown, the air holes 308 are arranged on the pressing plate 307 and penetrate the pressing plate 307, and the suction nozzles on the air plate 306 penetrate the air holes 308. The avoiding hole 309 penetrates the pressing plate 307 to avoid the insertion rod 204 below when sucking the stator sheet to avoid interference with the insertion rod 204.

[0048] By fixing the pressing plate 307 at the bottom of the air plate 306, when sucking a stator sheet on the uppermost layer of the inner lifting disc 203, the pressing plate 307 is pressed on the stator sheet on the uppermost layer of the inner lifting disc 203, and then the stator sheet is sucked by the suction nozzles on the air plate 306. The pressing plate 307 can ensure the levelness of the stator sheet. If only the suction nozzles are used for sucking, the levelness of the stator sheet cannot be ensured during sucking and transferring due to the limited sucking position, which will directly affect the subsequent assembly of the stator sheet.

[0049] As shown in Figure 10 The lifting slide 310 is fixed on the side of the transfer frame 301 close to the rotating disc 201, the second lifting plate 311 is connected to the lifting slide 310, the separation disc 312 is fixed on the sliding part of the lifting slide 310, and the separation disc 312 is driven to move up and down by the lifting slide 310. The separation air block 313 is arranged on the inner side wall of the annular separation disc 312, the nozzle is connected to the separation air block 313 and is connected to the air pump, and the air groove 314 is arranged on the inner side of the separation air block 313 and is arranged horizontally. The air groove 314 is connected to the nozzle.

[0050] When the suction nozzle sucks a stator sheet on the uppermost layer of the inner lifting disc 203, the second layer of stator sheets may be brought up due to the contact between the first layer of stator sheets and the second layer of stator sheets. Therefore, the inner side of the separation air block 313 is arranged to blow air to separate the stator sheet on the uppermost layer from the second layer of stator sheets.

[0051] As shown in Figure 11 The dipping frame 315 is fixed on the rack 1 by screw fastening, the dipping disc 316 is fixed on the top of the dipping frame 315, and the dipping groove is annular and arranged on the top of the dipping disc 316. The dipping groove is filled with activator, and the dipping sponge 317 is placed in the dipping groove to adsorb the activator in the dipping groove. When the suction nozzle sucks a stator sheet on the uppermost layer of the inner lifting disc 203 and places it on the dipping sponge 317, the lower surface of the stator sheet will adsorb the activator, which is convenient for subsequent gluing.

[0052] The height of the impregnation sponge 317 is equal to the depth of the impregnation tank, so that the lower surface of the stator sheet can absorb sufficient activator. By arranging the impregnation sponge 317, the activator can be evenly applied on the bottom of the stator sheet, and the activator can be prevented from flowing to the upper surface of the stator sheet, so that the activator is not wasted and the upper surface of the stator is not contaminated.

[0053] After impregnation, the stator sheet is transferred to a subsequent glue applicator, and the glue applicator applies glue on the upper surface of the stator sheet. Finally, when the stator sheet is laminated and assembled, the activator of the adjacent two stator sheets is in contact with the glue, so that the adhesion of the stator sheet is improved.

[0054] The working principle of the stator sheet assembly feeding structure is as follows:

[0055] The servo motor 206 drives the turntable 201 to rotate to a suitable position, the jacking cylinder 207 drives the jacking block 208 to rise, the inner lifting disc 203 and the stator sheet are pushed up by the jacking block 208, the uppermost stator sheet on the inner lifting disc 203 is sucked by the suction nozzle, at the same time, the uppermost stator sheet is separated from the second layer stator sheet under the cooperation of the separation air block 313, so that the second layer stator sheet is prevented from being lifted (the setting of the pressing plate 307 can ensure the horizontal degree of the stator sheet when sucking) ;

[0056] The stator sheet is placed on the impregnation sponge 317 under the driving of the linear slide 302, so that the lower surface of the stator sheet can absorb uniform activator, and the subsequent adhesion of the stator is facilitated.

[0057] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable persons skilled in the art to understand the content of the utility model and implement it, and cannot limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit and essence of the utility model shall be covered within the protection scope of the utility model.
