A blanking plate 33 which is obliquely arranged in the same direction with the first blanking strips 32 is welded between the positions of the first blanking strips 32 close to the top ends, and the blanking plate 33 is positioned below the receiving plate 54. The stator and rotor sheets slide from the receiving plate 54 onto the blanking plate 33 and continue to slide obliquely downward in the oblique direction of the blanking plate 33.

Referring to fig. 1, 3 and 4, the sorting device 3 further comprises a receiving hopper 34 welded under the two first blanking strips 32, the receiving hopper 34 being located close to the lower extremity of the blanking plate 33.

Referring to fig. 1, 3 and 4, since the distance between the two first blanking strips 32 is greater than the diameter of the rotor sheet, after the stator sheet and the rotor sheet slide down from the blanking plate 33, the rotor sheet falls into the receiving hopper 34 from between the two first blanking strips 32 and slides out through the two second blanking strips 35 at the discharge port at the bottom of the receiving hopper 34, while the stator sheet continues to slide down obliquely on the two first blanking strips 32.

Referring to fig. 1, 3 and 4, a bottom plate 36 is provided between the bottom ends of the two second blanking bars 35, a striker plate 37 is hinged to the bottom plate 36, and a torsion spring (not shown) is supported between the striker plate 37 and the bottom plate 36. The deformation force of the torsion spring acts on the rotor sheet through the striker plate 37 so that the rotor sheet is stacked obliquely in order at a position near the bottom on the two second blanking bars 35.

Referring to fig. 1, 5 and 6, the sheet arranging device 6 includes a conveyor belt 61 placed on the ground and a mounting box 62, one end of the conveyor belt 61 extends to the bottom end of the first blanking strip 32, and the other end is close to the mounting box 62.

The installation box 62 is internally provided with a hydraulic cylinder 63, a piston rod of the hydraulic cylinder 63 is connected with a horizontal supporting table 64, a sleeve 65 is rotatably arranged on the supporting table 64, and the sleeve 65 slides from the top of the installation box 62 and rotates out.

The supporting table 64 is bolted with a second motor 66, a gear 67 is fixedly sleeved on the output shaft of the second motor 66, and a toothed ring 68 meshed with the gear 67 is fixedly sleeved on the sleeve 65. The support table 64 is also fixedly provided with a vertical clamping strip 69, the clamping strip 69 slides out from the top of the mounting box 62, and the clamping strip 69 is used for being in sliding fit with a clamping groove on the circumferential outer side wall of the stator piece.

Referring to fig. 1, 5 and 6, the stator piece slides off the first blanking strip 32 onto the conveyor belt 61 and then fits over the sleeve 65 when it falls off the conveyor belt 61. The output shaft of the second motor 66 drives the sleeve 65 to rotate through the engagement of the gear 67 and the toothed ring 68, and the sleeve 65 drives the stator plate to rotate through friction.

When the stator piece rotates to the point that the clamping groove on the outer side wall of the circumference of the stator piece is aligned with the clamping strip 69, the stator piece slides downwards on the sleeve 65 under the action of gravity, and the clamping strip 69 is in sliding fit with the clamping groove. In the above manner, a plurality of stator pieces are stacked in order.

Referring to fig. 1, 5 and 6, a limit roller 7 is rotatably installed at the top of the conveyor belt 61 opposite to one end of the mounting box 62, and a gap is provided between the limit roller 7 and the conveyor belt 61. When the stator piece drops from the conveyer belt 61, the limit roller 7 can limit the inclination angle of the stator piece, so that the possibility that the stator piece is difficult to be sleeved on the sleeve 65 due to overlarge inclination degree is reduced.

Referring to fig. 1, 5 and 6, the sleeve 65 is circumferentially provided with a plurality of limit stops 8 with respect to the remaining side of the conveyor belt 61, the mounting box 62 is bolted with the mounting frame 9, and the plurality of limit stops 8 are all bolted on the mounting frame 9. When the stator piece falls from the conveyer belt 61, the plurality of limit baffles 8 cooperate to play a role in positioning the positioning piece, so that the stator piece can be accurately sleeved on the sleeve 65.

The mounting frame 9 is formed by detachably assembling a plurality of components, so that the position of each limit baffle 8 can be adjusted according to actual use conditions.

Referring to fig. 1, 5 and 6, the top of the mounting box 62 is bolted with the cylinder 10, the piston rod of the cylinder 10 facing the sleeve 65 and being screwed with the stripper plate 11. After a certain number of stator plates have been stacked, the piston rod of the hydraulic cylinder 63 is retracted, thereby bringing the sleeve 65 and the snap strip 69 to retract into the mounting box 62. After that, the piston rod of the air cylinder 10 is extended, the pushing plate 11 can push away the stator sheet stack which is orderly stacked, and the sleeve 65 is moved out of the mounting box 62 again for the next sheet arranging work.

The implementation principle of the automatic stator and rotor punching sheet arranging production line is as follows:

when the strip is unwound, the strip may drop to contact the balls 422 on the pad 421, and at this time, the strip, the pad 421 and the balls 422 cooperate with other components to form a closed-loop circuit, and the current detection sensor 424 may detect whether or not the current passes through the closed-loop circuit.

When the current detection sensor 424 detects that current is passing, the control system turns off the first motor 413, stopping unreeling the tape. When the deflection feeder 1 feeds the strip so that the strip is separated from contact with the balls 422, the closed loop circuit is disconnected, no current passes through the current detection sensor 424, and the control system starts the first motor 413 to unwind the strip.

The deflection feeding machine 1 feeds the strip into the press 21, the upper die 22 moves downwards, and the strip is matched with the lower die 23 to realize punching. When the upper die 22 moves upward, the stator plate and the rotor plate are driven to move upward together.

After the stator sheet and the rotor sheet slide down from the blanking plate 33, the rotor sheet falls into the receiving hopper 34 from between the two first blanking strips 32, and slides out through the two second blanking strips 35 at the discharging port at the bottom of the receiving hopper 34, the deformation force of the torsion spring acts on the rotor sheet through the baffle plate 37, so that the rotor sheet is sequentially stacked in an inclined manner at the position of the second blanking strip 35 near the bottom, and the stator sheet continuously slides down obliquely onto the conveying belt 61 on the two first blanking strips 32.

When the stator piece falls off the conveyor belt 61, the stator piece is exactly sleeved on the sleeve 65. The output shaft of the second motor 66 drives the sleeve 65 to rotate through the engagement of the gear 67 and the toothed ring 68, and the sleeve 65 drives the stator plate to rotate through friction. When the stator piece rotates to the point that the clamping groove on the outer side wall of the circumference of the stator piece is aligned with the clamping strip 69, the stator piece slides downwards on the sleeve 65 under the action of gravity, and the clamping strip 69 is in sliding fit with the clamping groove. Through the mode, a plurality of stator sheets are stacked in sequence, and then sheet arrangement is achieved.

After a certain number of stator plates are stacked, the piston rod of the hydraulic cylinder 63 is retracted, thereby driving the sleeve 65 and the clamping strip 69 to retract into the mounting box 62. After which the piston rod of the cylinder 10 is extended and the stripper plate 11 can push the stack of stator sheets in order, after which the sleeve 65 is removed again from the mounting box 62 for the next sheet-sorting operation.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
