During the production of traction motors, the iron core of the traction motor is made of multiple silicon steel sheets stacked up and down. When stacking, it is necessary to consider the stacking angle of each silicon steel sheet and the alignment of the punched notches on the outer edge of each silicon steel sheet, so that the punched holes on each silicon steel sheet can be aligned. These holes are used for the insertion of conductive bars in the later stage and the heat dissipation of the iron core.

DETAILED DESCRIPTION

[0042] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0043] Reference Figure 1 - Figure 8, an automatic lamination device for producing electric motors for rail vehicles, comprising a material table 1, a column 2 is arranged in the middle position of the upper surface of the material table 1; it also comprises a horizontal plate 3 arranged along the length direction of the material table 1, and a No. 1 cylinder 6 whose cylinder body penetrates the horizontal plate 3, and the No. 1 cylinder 6 can reciprocate along the length direction of the horizontal plate 3; a cover plate 7 is rotatably arranged at the output end of the No. 1 cylinder 6; a plurality of suction cups 8 and a camera 9 are arranged on the edge of the lower surface of the cover plate 7;

[0044] The camera 9 is used to capture and obtain images of the silicon steel sheets 101 to be stacked, and transmit the images to the back-end central control system, which determines the placement state of the silicon steel sheets 101 and determines the rotation angle of the silicon steel sheets 101 that needs to be adjusted;

[0045] The cover plate 7 is used to drive a plurality of suction cups 8 to be adsorbed on the upper surface of the silicon steel sheet 101. The cover plate 7 is rotated to drive the silicon steel sheet 101 to rotate to the target angle. The movement of the No. 1 cylinder 6 transfers the silicon steel sheet 101 to the top of the column 2. The suction cup 8 releases the silicon steel sheet 101, and the silicon steel sheet 101 falls and is sleeved on the outer ring of the column 2.

[0046] In this embodiment, a screw rod 4 is provided on the horizontal plate 3, an execution block 5 is threadedly connected to the screw rod 4, and a No. 1 cylinder 6 is fixedly connected to the execution block 5; the screw rod 4 is driven to rotate by a motor 29, and the screw rod 4 rotates and can drive the execution block 5 to reciprocate along the length direction of the horizontal plate, and at the same time realize the reciprocating movement of the No. 1 cylinder 6 along the length direction of the horizontal plate 3, and the motor 29 is controlled and executed by a central control system, which can control the motor 29 to rotate forward and reverse;

[0047] In this embodiment, the output end of the No. 1 cylinder 6 is connected to the cover plate 7 through a driving assembly, and the driving assembly includes a servo motor 35, a driving tooth 36 and a driven tooth 37; the end shell of the servo motor 35 is fixedly connected to the outer wall of the output end of the No. 1 cylinder 6, the output end of the servo motor 35 is fixedly connected to the driving tooth 36, the driving tooth 36 meshes with the driven tooth 37, the upper end of the driven tooth 37 is rotatably connected to the output end of the No. 1 cylinder 6, the lower end surface of the driven tooth 37 is fixedly connected to the upper end surface of the cover plate 7, and the driving assembly can drive the cover plate 7 to perform circular motion around the axis of the output end of the No. 1 cylinder 6;

[0048] The central control system determines the method of adjusting the angle based on the photo of the silicon steel sheet 101 collected by the camera 9 based on the existing technology, and those skilled in the art can choose according to the needs. Two methods are provided in the embodiment of the present application, as follows:

[0049] Reference Fig.16 The baseline determination method can be based on the hole position on each silicon steel sheet 101, such as Fig.16As shown in the figure, it is one of the situations of the placement angle of the silicon steel sheet 101 photographed. The center of the silicon steel sheet 101 is taken as the center, and a vertical reference line A is marked in the middle of its upper half. The center of any one of the holes is taken as a fixed point, and the fixed points are connected to form a dotted line B. Then, the angle R between the straight line and the reference line is measured. The angle R is the angle that the silicon steel sheet 101 needs to adjust and rotate later. After the rotation, the center of one of the holes will fall on the reference line A, and the center of one of the holes on all subsequent silicon steel sheets 101 will overlap and fall on the reference line.

[0050] The overlap comparison method pre-sets a placement state of a silicon steel sheet 101, that is, one of the punching notches of the pre-set silicon steel sheet 101 is vertically facing upward, and the image captured by the silicon steel sheet 101 in this state is used as a reference image, and the image of the silicon steel sheet 101 to be stacked is captured by the camera 9 as a comparison image, and the reference image and the comparison image are overlapped and compared, and specifically compare the position of any punching notch on the reference image with the position of the punching notch facing vertically upward on the comparison image, and the central control system simulates the rotation angle required for any punching notch on the reference image to overlap with the position of the punching notch facing vertically upward on the comparison image, and the rotation angle is the target angle, and when stacked subsequently, any punching notch on all silicon steel sheets 101 will be in an overlapped state;

[0051] The suction cup 8 is connected to an external electrical control system. When the suction cup 8 absorbs the silicon steel sheet 101, the electrical control system controls the operation of the external negative pressure pump and forms a negative pressure environment in the suction cup 8.

[0052] In this embodiment, each silicon steel sheet 101 processed by punching is stacked one by one in advance to prepare the materials. When loading is required, the whole stack of silicon steel sheets 101 is transferred to the bottom of the end of the cross plate 3 by a forklift and placed horizontally on the material table 1. At this time, the line segment formed by the center of the silicon steel sheet 101 and the center of the column 2 is parallel to the length direction of the cross plate 1. Later, the automatic lamination device for producing motors for rail trains is used to grab them one by one and put them on the column 2. The automatic lamination device for producing motors for rail trains specifically works as follows:

[0053] Step 1: Picking up, the central control system controls the motor 29 to drive the screw rod 4 to rotate, the screw rod 4 drives the execution block 5 to move, the execution block 5 moves to the top of the silicon steel sheet 101 to be stacked, and then the motor 29 is paused, and the No. 1 cylinder 6 is driven, the No. 1 cylinder 6 drives the cover plate 7 to move down, and at the same time, the camera 9 on the cover plate 7 takes pictures of the silicon steel sheet 101 to be stacked, and the pictures taken are transmitted to the central control system, and the placement state of the silicon steel sheet 101 at this time is identified and judged, and then the rotation angle of the subsequent loading and stacking of the silicon steel sheet 101 is calculated, so that the holes of each silicon steel sheet 101 are aligned before stacking; after the central control system calculates the rotation angle, the No. 1 cylinder 6 has driven the cover plate 7 to move to the top of the silicon steel sheet 101, and then the suction cup 8 adsorbs the silicon steel sheet 101;

[0054] Step 2: Transfer: The suction cup 8 maintains negative pressure inside to absorb the silicon steel sheet 101, and then the No. 1 cylinder 6 drives the silicon steel sheet 101 to move upward. During the upward movement, the servo motor 35 drives the cover plate 7 to rotate, and the rotation angle is the rotation angle calculated by the central control system. During the angle adjustment of the silicon steel sheet 101, the screw rod 4 drives the execution block 5 to move above the column 2, that is, the silicon steel sheet 101 absorbed by the suction cup 8 is transferred to the top of the column 2;

[0055] Step 3: Release: After the silicon steel sheet 101 is transferred to the top of the column 2, the execution block 5 is paused. At this time, the center circle of the silicon steel sheet 101 is aligned with the upper end surface of the column 2, and the No. 1 cylinder 6 drives the silicon steel sheet 101 to move down. The center circle of the silicon steel sheet 101 is set on the column 2. At the same time, the electrical control system controls the suction cup 8 to lose the negative pressure environment, and the silicon steel sheet 101 loses the adsorption of the suction cup 8, and moves down along the height direction of the column 2 under its own gravity, and falls on the material table 1, and then the No. 1 cylinder 6 moves up and resets, and the stacking operation of a silicon steel sheet 101 is completed at this time;

[0056] According to the above-mentioned step 1 picking up, step 2 transferring and step 3 releasing process, the operations are performed in sequence and repeated, and the loading of the silicon steel sheet 101 can be completed automatically. The mechanization level is high, the degree of personnel participation is reduced, and manual operation is reduced. It can not only reduce the production safety risk, but also improve the stacking efficiency of the silicon steel sheet 101 and the neatness of the silicon steel sheet 101, which is helpful to improve the quality of the rail train motor rotor.

[0057] Reference Figure 1 - Fig. 9 A plurality of through holes 10 are arranged in a circular array in the middle of the material table 1, and a guide rod 11 is passed through each through hole 10. A second cylinder 12 is fixedly connected to the lower end of each guide rod 11, and a cone 13 is arranged at the upper end of each guide rod 11 and is inclined toward the outer side of the column 2;

[0058] The through holes 10 are arranged in a circular array outside the column 2, and the guide rods 11 are slidably connected in the through holes 10. The outer circle gap of the guide rods 11 matches the punching notch of the outer edge of the silicon steel sheet 101. The guide rods 11 cooperate with the cone 13 to guide the silicon steel sheet 101 to fall, so that each silicon steel sheet 101 can be stacked together stably. The specific operation is that during the release process of the silicon steel sheet 101, the No. 2 cylinder 12 drives the guide rod 11 to move upward, so that the cone 13 moves to the upper end position of the column 2. At this time, the punching notches on the outer edge of the silicon steel sheet 101 are aligned with the cone 13 one by one. The conical bodies 13 are relative to each other, and the No. 1 cylinder 6 drives the silicon steel sheet 101 to move downward. The conical bodies 13 are placed one by one in the edge punching notches of the silicon steel sheet 101, and then the suction cup 8 releases the silicon steel sheet 101. The silicon steel sheet 101 moves downward under its own gravity and moves downward along the conical body 13 and the guide rod 11. At the same time, the No. 2 cylinder 12 drives the guide rod 11 to move downward. During the downward movement of the silicon steel sheet 101, the guide rod 11 constrains the rotation of the silicon steel sheet 101, so that the silicon steel sheet 101 moves vertically downward, thereby improving the neatness of the stacking of the upper and lower silicon steel sheets 101.

[0059] Reference Figure 1 - Figure 6 , the number of No. 1 cylinders 6 arranged on the horizontal plate 3 is two, the screw rod 4 is threadedly connected with two execution blocks 5, and each execution block 5 is provided with a No. 1 cylinder 6; trays 14 are provided on both sides of the upper surface of the material table 1, and multiple silicon steel sheets 101 to be laminated are placed on each tray 14;

[0060] Two trays 14 are symmetrically arranged on the material table 1, and the trays 14 are horizontally stacked with silicon steel sheets 101 to be laminated. Figure 3 As shown, when the execution block 5 on the left moves to above the tray 14 on the left side of the material table 1, the suction cup 8 is used to pick up the silicon steel sheet 101, and at the same time, the execution block 5 on the right moves to above the column 2, and the suction cup 8 is used to release the silicon steel sheet 101. The picking operation and the releasing operation are performed synchronously without interfering with each other. Similarly, when the picking operation of the silicon steel sheet 101 by the suction cup 8 on the left is completed, the releasing operation of the silicon steel sheet 101 by the suction cup 8 on the right is also completed, that is, the synchronization is completed. Thereafter, the execution block 5 on the right moves to the right, and the execution block 5 on the left moves to the right. The execution block 5 on the right moves from the position above the column 2 to above the right tray 14, and the execution block 5 on the left moves from above the tray 14 to above the column 2, and then the picking operation and the releasing operation are performed synchronously, and so on. The above operations are repeated to make full use of the time interval between the suction cup 8 picking up the silicon steel sheet 101 and releasing the silicon steel sheet 101, and the stacking efficiency of the silicon steel sheet 101 is doubled.

[0061] Reference Figure 1 - Fig.10The bottom of the column 2 is provided with a material plate 15, the middle of the material plate 15 is sleeved on the outer ring of the column 2, a plurality of clearance openings 16 are provided on the edge of the material plate 15, and the guide rod 11 is placed in the clearance opening 16;

[0062] The material platform 1 has two first-numbered recesses 17 at both edges in the middle, and a cylindrical platform 18 is formed between the two first-numbered recesses 17. The column 2 is fixedly connected to the middle position of the upper surface of the cylindrical platform 18. Two grooves 19 are formed on the upper surface of the cylindrical platform 18, and the grooves 19 are located on both sides of the column 2.

[0063] The material plate 15 is in a ring shape as a whole. The middle of the material plate 15 is sleeved on the outer ring of the column 2. The guide rod 11 is placed in the clearance opening 16 on the material plate 15. The outer ring of the guide rod 11 is gap-matched with the inner wall of the clearance opening 16. Two parallel grooves 19 are set on the cylindrical platform 18. The grooves 19 are set along the width direction of the material platform 1. When the stacking operation of the silicon steel sheets 101 on the column 2 is completed, the neatly stacked silicon steel sheets 101 need to be removed. At this time, the material can be unloaded by a forklift. , insert the fork of the forklift along the groove 19, and lift the material plate 15 vertically upward to lift the entire stack of silicon steel sheets 101. In order to ensure the stability of the stacked silicon steel sheets 101, two or more conductive strips can be inserted along the holes on the silicon steel sheets 101 in advance to restrain the entire stack of silicon steel sheets 101 together, and then lift it up by forklift; the groove 19 cooperates with the setting of the material plate 15 to facilitate the removal of the stacked silicon steel sheets 101.

[0064] Reference Figure 1 - Fig.14 The material table 1 has a second recess 20 on both sides, the tray 14 is placed flat in the second recess 20, and a third recess 21 is symmetrically formed on the lower surface of the tray 14;

[0065] The provided pallet 14 can be used to stack the silicon steel sheets 101 on the pallet 14 in advance, and then be transferred to the material platform 1 by a forklift at a later time. Meanwhile, three recesses 21 are symmetrically provided on the lower surface of each pallet 14, so that the fork rod of the forklift can be inserted under the three recesses 21, and the entire stack of silicon steel sheets 101 can be transferred to the material platform 1, so as to facilitate the replenishment of the silicon steel sheets 101 materials.

[0066] Reference Figure 1 - Fig.12 Each of the second recesses 20 has a circular opening, in which a lifting plate 22 is provided, a plurality of third cylinders 23 are fixedly connected to the lower surface of the lifting plate 22, and a tray 14 is placed flat on the upper surface of the lifting plate 22;

[0067] Considering the consumption of silicon steel sheets 101 on the tray 14, the stacking height of silicon steel sheets 101 is gradually reduced. Each time the No. 1 cylinder 6 drives the cover plate 7 to move downward, the downward stroke of the output end of the No. 1 cylinder 6 will gradually increase. The stroke amount increases, and the time consumed for picking up is prolonged, which will reduce the stacking efficiency of the silicon steel sheets 101. For this purpose, a lifting plate 22 is set, and the No. 3 cylinder 23 can drive the lifting plate 22 to move up and down. The tray 14 is placed horizontally on the lifting plate 22, which can realize the up and down movement of the tray 14;

[0068] Each time a silicon steel sheet 101 is consumed on the tray 14, the No. 3 cylinder 23 will push the lifting plate 22 upward, and the upward stroke is the thickness of a silicon steel sheet 101, so that the silicon steel sheet 101 on the top of the tray 14 is always at a specified height, ensuring that the output end of the No. 1 cylinder 6 moves downward by the same amount each time, avoiding the consumption of silicon steel sheets 101, reducing the stacking height, increasing the downward stroke of the output end of the No. 1 cylinder 6, and reducing the stacking efficiency of the silicon steel sheets 101.

[0069] Reference Fig.13 - Fig.15 A plurality of insertion holes 24 are provided in a circumferential array on each of the trays 14, and a limiting rod 25 is inserted in each insertion hole 24, and the limiting rod 25 is embedded in a punching notch on the outer edge of the silicon steel sheet 101;

[0070] After processing, each silicon steel sheet 101 will be pre-stacked on the pallet 14. In order to facilitate the subsequent picking operation of the suction cup 8, a limit rod 25 is set on the pallet 14. The limit rod 25 is used to constrain the silicon steel sheets 101 to be stacked, ensuring that the edges of the upper and lower silicon steel sheets 101 are in a neat state, which is convenient for the subsequent adsorption of the suction cup 8. When the silicon steel sheets 101 on the pallet 14 are transferred by a forklift, the limit rod 25 can constrain the silicon steel sheets 101 to be stable and motionless, avoiding the vibration generated during the movement of the forklift, which causes the silicon steel sheets 101 to slip horizontally and affect the subsequent adsorption of the suction cup 8; after the silicon steel sheets 101 are transferred to the material table 1, the limit rod 25 can be removed, and then the stacking operation can be carried out.

[0071] Reference Figure 7 - Fig. 9A sliding opening 26 is provided inside the column 2, and the sliding opening 26 vertically penetrates downward to the upper surface of the cylindrical platform 18, and the sliding opening 26 horizontally penetrates to the outside of the column 2, and a lifting rod 27 is provided in the middle position of the sliding opening 26, and the lower end of the lifting rod 27 penetrates below the material platform 1 and is fixedly connected to a No. 4 air cylinder 28, and a motor 29 is fixedly connected to the upper end of the lifting rod 27, and the output end of the motor 29 is vertically upward and is fixedly connected to a turntable 30, and the turntable 30 is rotatably connected to a push-pull rod 31 at an eccentric position, and the end of the push-pull rod 31 extends horizontally along the sliding opening 26 toward the outside of the column 2, and the end of the push-pull rod 31 is rotatably connected to an arc plate 32, and the outer arc surface of the arc plate 32 can be pressed and attached to the inner ring surface of the silicon steel sheet 101;

[0072] The silicon steel sheets 101 are stacked one by one. Each time a sheet is stacked, the motor 29 will drive the turntable 30 to deflect, and the turntable 30 will push the push-pull rod 31 to move toward the inner circle of the silicon steel sheet 101. The end of the push-pull rod 31 is rotatably connected to the arc plate 32, and the push-pull rod 31 will push the arc plate 32 to squeeze on the inner circle of the silicon steel sheet 101. The curvature of the outer arc surface of the arc plate 32 is the same as the inner and outer curvatures of the silicon steel sheet 101, and the arc plate 32 will squeeze multiple silicon steel sheets 101 each time, so that the multiple silicon steel sheets 101 tend to be neat, thereby improving the neatness of the stacking of the silicon steel sheets 101. At the same time, after each silicon steel sheet 101 is stacked, the No. 4 cylinder 28 will drive the motor 29 to move upward, and the upward stroke is equal to the thickness of a silicon steel sheet 101, to ensure that the arc plate 32 can squeeze the stacked silicon steel sheets 101.

[0073] Reference Figure 7 - Fig. 9 The outer wall of the column 2 is symmetrically provided with four recesses 33, which are arranged along the height direction of the column 2, and the four recesses 33 are arranged to overlap with the sliding opening 26, and the arc plate 32 can move into the four recesses 33;

[0074] After the arc plate 32 completes extrusion, the motor 29 drives the turntable 30 to reverse, the push-pull plate pulls the arc plate 32 back to its original position, and pulls the arc plate 32 into the fourth recess 33. The arc plate 32 is placed in the fourth recess 33 to ensure that there are no protrusions on the outer surface of the main body, so that the subsequent silicon steel sheets 101 can be smoothly dropped and stacked.

[0075] Reference Figure 7 - Figure 8A plurality of jet holes 34 are provided on the upper surface of the column 2, and the jet direction of the jet holes 34 is tilted downward; a plurality of jet holes 34 are provided on the column 2, and the jet direction of the jet holes 34 is tilted downward, and the jet holes 34 are connected to an external air pump through a pipeline at the bottom of the column 2, and the air pump continuously injects gas into the jet holes 34 and discharges the gas through the jet holes 34. When the silicon steel sheet 101 moves down along the column 2, the gas will impact the silicon steel sheet 101, causing the silicon steel sheet 101 itself to vibrate, which is conducive to the smooth and rapid fall of the silicon steel sheet 101. At the same time, the gas ejected from the jet holes 34 impacts the surface of the silicon steel sheet 101, and foreign matter on the surface of the silicon steel sheet 101 can be impacted and discharged, thereby achieving the cleaning of the silicon steel sheet 101.

[0076] Working principle:

[0077] Picking: The central control system controls the motor 29 to drive the screw rod 4 to rotate, and the screw rod 4 drives the execution block 5 to move, and the execution block 5 moves to the top of the silicon steel sheet 101 to be stacked, and then the motor 29 is paused, and the No. 1 cylinder 6 is driven, and the No. 1 cylinder 6 drives the cover plate 7 to move down, and at the same time, the camera 9 on the cover plate 7 takes pictures of the silicon steel sheet 101 to be stacked, and the pictures taken are transmitted to the central control system, and the placement state of the silicon steel sheet 101 at this time is identified and judged, and then the rotation angle of the subsequent loading and stacking of the silicon steel sheet 101 is calculated, so that the holes of each silicon steel sheet 101 are aligned before stacking; after the central control system calculates the rotation angle, the No. 1 cylinder 6 has driven the cover plate 7 to move to the top of the silicon steel sheet 101, and then the suction cup 8 adsorbs the silicon steel sheet 101;

[0078] Transfer: The suction cup 8 maintains negative pressure inside to absorb the silicon steel sheet 101, and then the No. 1 cylinder 6 drives the silicon steel sheet 101 to move upward. During the upward movement, the servo motor 35 drives the cover plate 7 to rotate, and the rotation angle is the rotation angle calculated by the central control system. During the angle adjustment of the silicon steel sheet 101, the screw rod 4 drives the execution block 5 to move above the column 2, that is, the silicon steel sheet 101 absorbed by the suction cup 8 is transferred to the top of the column 2;

[0079] Release: When the silicon steel sheet 101 is transferred to the top of the column 2, the execution block 5 is paused. At this time, the center circle of the silicon steel sheet 101 is aligned with the upper end surface of the column 2, and the No. 1 cylinder 6 drives the silicon steel sheet 101 to move down. The center circle of the silicon steel sheet 101 is set on the column 2. At the same time, the electrical control system controls the suction cup 8 to lose the negative pressure environment. The silicon steel sheet 101 loses the adsorption of the suction cup 8 and moves down along the height direction of the column 2 under its own gravity and falls on the material table 1. Then the No. 1 cylinder 6 moves up and resets. At this time, the stacking operation of a silicon steel sheet 101 is completed;

[0080] Unloading: After stacking the silicon steel sheets 101 to a specified height on the column 2, unloading is performed by a forklift. The fork bar of the forklift is inserted along the groove 19, and the material plate 15 is lifted vertically upward to lift and remove the entire stack of silicon steel sheets 101.

[0081] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
