Description

Technical Field

[0001] The present application belongs to the technical field of stator and rotor production, and specifically relates to a stator and rotor production and processing device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It is widely used in various devices and systems. The composition of a motor is relatively complex, but it mainly includes a stator and a rotor. The stator and the rotor cooperate with each other through the action of magnetic coils to convert electromagnetic energy into mechanical energy. At present, stamping and forming processes are usually used to produce stators and rotors.

[0003] In the related art, a stamping device for producing a stator and a rotor includes a lower die and an upper die arranged opposite to the lower die and located above the lower die, the upper die can move relative to the lower die so that the material strip is stamped to form silicon steel sheets for the rotor and silicon steel sheets for the stator, and the lower die has a stacking station for the silicon steel sheets for the rotor and a stacking station for the silicon steel sheets for the stator to achieve stacking of the silicon steel sheets for the rotor and the silicon steel sheets for the stator in the stamping device; however, since there may be gaps between the multiple silicon steel sheets located at the stacking stations or the silicon steel sheets may be skewed, this can easily lead to uneven thickness of the stator and rotor after forming, thereby affecting the production quality of the stator and rotor. Summary of the invention

[0004] The present application provides a stator and rotor production and processing device to solve at least one of the above-mentioned technical problems.

[0005] The technical solution adopted in this application is:

[0006] A stator and rotor production and processing device, comprising:

[0007] A lower die, the lower die having a rotor stamping station, a rotor stacking station located behind the rotor stamping station, a stator stamping station located behind the rotor stacking station, and a stator stacking station located behind the stator stamping station;

[0008] An upper die, the upper die being located above the lower die and being able to move in a direction approaching or away from the lower die, the upper die being provided with a rotor punching die head corresponding to the rotor punching station, a rotor pressing structure corresponding to the rotor stacking station, a stator punching die head corresponding to the stator punching station, and a stator pressing structure corresponding to the stator stacking station;

[0009] When the upper die moves toward the lower die, the rotor stamping die head and the stator stamping die head stamp the material strip, and the rotor pressure structure is used to apply downward pressure to the silicon steel sheets located at the rotor stacking station, and the stator pressure structure is used to apply downward pressure to the silicon steel sheets located at the stator stacking station.

[0010] By adopting the above technical solution, when producing the stator and rotor, the material strip is extended from one end of the stator and rotor production and processing device between the upper die and the lower die, and then the upper die moves in the direction close to the lower die, and then the rotor stamping die head stamps the material strip so that a partial area of ​​the material strip forms a silicon steel sheet for the rotor, and then the upper die moves in the direction away from the lower die, and the formed silicon steel sheet for the rotor is placed in the rotor stacking position under the action of the manipulator, and the material strip continues to move so that the material strip with the rotor part punched out moves to the stator stamping station, and the upper die moves in the direction of the lower die, so that the stator stamping die head stamps the material strip so that a partial area of ​​the material strip forms a silicon steel sheet for the stator, and then The upper die moves in a direction away from the lower die, and the formed stator silicon steel sheets are placed in the stator stacking position under the action of the robot, and then the upper steps are cycled to obtain multiple rotor silicon steel sheets and stator silicon steel sheets; when the upper die moves in a direction close to the lower die, the rotor pressure structure applies downward pressure to the silicon steel sheets in the rotor stacking station, and the stator pressure structure applies downward pressure to the silicon steel sheets in the stator stacking station, so that the two adjacent silicon steel sheets are tightly attached to eliminate the gap between the two adjacent silicon steel sheets, while avoiding the offset of the silicon steel sheets, thereby avoiding the uneven thickness of the stator and rotor, and thus improving the production quality of the stator and rotor.

[0011] Optionally, the rotor pressure structure and the stator pressure structure both include an elastic column having a connecting end connected to the upper mold and a pressure end opposite to the connecting end, and the pressure end is provided with a pressure member capable of contacting the silicon steel sheet.

[0012] By adopting the above technical solution, when the upper mold moves downward, the upper mold drives the elastic column to move downward, and then the elastic column drives the pressure member to move downward, so that the pressure member contacts the silicon steel sheet and applies downward pressure to the silicon steel sheet, thereby overcoming the bias of the silicon steel sheet, so that two adjacent silicon steel sheets are tightly attached to avoid the uneven thickness of the stator and rotor. At the same time, due to the setting of the elastic column, the pressure member can apply elastic pressure to the silicon steel sheet, so that the pressure member can adjust itself, so as to avoid the phenomenon that the pressure member applies a large pressure on the silicon steel sheet and causes the silicon steel sheet to deform, so as to ensure the production quality of the stator and rotor.

[0013] Optionally, the elastic column includes a first rod having a receiving cavity, a second rod passing through the receiving cavity, and an elastic portion provided in the receiving cavity and acting on the second rod, and the pressure member is connected to one end of the bottom of the second rod.

[0014] By adopting the above technical solution, when the upper mold moves toward the direction close to the lower mold, the upper mold drives the first rod to move, and then the first rod drives the second rod to move toward the direction close to the lower mold, so that the pressure member contacts the silicon steel sheet, and then the upper mold continues to move toward the direction close to the lower mold. At this time, the second rod remains relatively stationary under the action of the silicon steel sheet, and the second rod applies pressure to the elastic part away from the lower mold. The elastic part deforms and applies a reverse force to the second rod, so that the pressure applied by the pressure member to the silicon steel sheet is maintained within a reasonable range. On the one hand, the pressure effect on the silicon steel sheet is guaranteed, and on the other hand, the deformation of the silicon steel sheet is avoided, so as to ensure the production quality of the stator and rotor.

[0015] Optionally, the elastic column further includes a limiting rod penetrating the second rod body, and a limiting groove for accommodating the limiting rod is provided on a side of the first rod body, and the limiting groove is arc-shaped.

[0016] By adopting the above technical solution, since the limiting rod is penetrated by the second rod body, the side of the first rod body is provided with a limiting groove for accommodating the limiting rod, and then the cooperation between the limiting rod and the limiting groove can limit the second rod body to avoid the second rod body from separating from the first rod body, thereby increasing the connection stability between the second rod body and the first rod body; and since the limiting groove is arc-shaped, then when the second rod body and the first rod body slide relative to each other, the second rod body can rotate around its own axis under the cooperation of the limiting rod and the limiting groove, so that the pressure member can apply a rotational force to the silicon steel sheet to overcome the thickness difference caused by the silicon steel sheet for the rotor and the silicon steel sheet for the stator being formed by stamping, thereby making the thickness of the stator and rotor more uniform, so as to further improve the production quality of the stator and rotor.

[0017] Optionally, the rotor stacking station and the stator stacking station are both provided with a stacking mold, and the stacking mold includes a stacking seat, a follower member and a driving assembly. The stacking seat has a accommodating space that penetrates itself in its axial direction, and the stacking seat is penetrated by the lower mold, the follower member is connected to the lower mold, and one end of the follower member extends into the accommodating space, the driving assembly is used to drive the stacking seat to rotate, and when the stacking seat and the lower mold rotate relative to each other, the follower member moves toward the outside of the stacking seat.

[0018] By adopting the above technical solution, after the manipulator places the silicon steel sheet in the accommodating space, the follower component blocks the silicon steel sheet located at the bottom layer, so that the silicon steel sheet stays stably in the accommodating space, so that multiple silicon steel sheets are stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or a silicon steel sheet is placed in the accommodating space, the driving component drives the stacking seat, and then the stacking seat and the lower mold rotate relative to each other at a certain angle. At this time, the silicon steel sheet that contacts the inner wall of the accommodating space slides relative to the inner wall of the accommodating space under the rotation of the stacking seat, so that two adjacent silicon steel sheets are completely fitted, and the influence of uneven workpiece thickness caused by stamping of the silicon steel sheet on the overall thickness of the stator and rotor is avoided, thereby ensuring the uniformity of the thickness of the stator and rotor, and further ensuring the production quality of the stator and rotor.

[0019] In addition, when the stacking seat and the lower die rotate relative to each other, the follower member moves toward the outside of the stacking seat under the action of the lower die and the stacking seat, so that after the silicon steel sheets are stacked to the required number, the follower member moves to the outside of the silicon steel sheets, so that the follower member and the bottom of the silicon steel sheets form a avoidance, so that the stacked silicon steel sheets fall through the bottom opening of the accommodating space to achieve the release of the stacked silicon steel sheets, so that the staff can carry out the next step of processing on the stacked silicon steel sheets, thereby greatly improving the production efficiency of the stator and rotor.

[0020] Optionally, the follower member has a connecting section and a stop section, the stop section is passed through the stacking seat, the lower mold has an arc groove extending along the circumference of the stacking seat, the distance between the arc groove and the accommodating space gradually increases along the circumference of the stacking seat, and the connecting section is passed through the arc groove.

[0021] By adopting the above technical solution, since the distance between the arc groove and the accommodating space gradually increases along the circumference of the stacking seat, and the connecting section is arranged in the arc groove, when the stacking seat and the lower mold rotate relative to each other, the follower member can rotate with the stacking seat under the action of the stop section, so that the connecting section of the follower member and the arc groove slide relative to each other, so that the follower member moves toward the outside of the stacking seat under the relative rotation of the stacking seat and the lower mold, so that as the number of silicon steel sheets stacked together increases, the stopper matching area between the stopper section and the silicon steel sheet becomes smaller and smaller, and finally, after the silicon steel sheets are stacked to the required number, the stopper section releases the stopper matching with the silicon steel sheet, so that the stacked silicon steel sheets fall through the bottom opening of the accommodating space. In addition, the groove wall of the arc groove can also limit the follower member to avoid the situation that the follower member rotates under the gravity of the silicon steel sheet, so as to increase the support stability of the follower member to the silicon steel sheet.

[0022] Optionally, the arc groove penetrates the lower mold in the axial direction, the stacking seat is provided with a through opening, the stop section is passed through the through opening, and the stacking seat is provided with an elastic member acting on the stop section, and the elastic member can apply an upward elastic force to the stop section.

[0023] By adopting the above technical scheme, since the arc groove penetrates the lower mold in the axial direction, and the stacking seat is provided with a through hole, the stop section is penetrated by the through hole, and the stacking seat is provided with an elastic member acting on the stop section, the stop section can elastically move in the axial direction of the stacking seat following the change in the number of silicon steel sheets. On the one hand, when the silicon steel sheets are placed in the accommodating space, the distance required for the silicon steel sheets to be placed to move is reduced, so as to reduce the phenomenon that the silicon steel sheets may contact the inner wall of the accommodating space and become offset, thereby further ensuring the uniformity of the thickness of the stator and rotor. On the other hand, as the number of silicon steel sheets placed above the stop section gradually increases, the stop section elastically moves downward to ensure that the required number of silicon steel sheets can be placed in the accommodating space, so as to ensure the production quality of the stator and rotor.

[0024] Optionally, the elastic member is a spring sleeved on the outside of the stacking seat, and the stacking seat has a supporting portion, and the supporting portion is located at the bottom of the spring to support the spring.

[0025] By adopting the above technical solution, since the support part is located at the bottom of the spring, the support part can support the spring to increase the elastic support effect of the spring on the stop section, and the spring is sleeved outside the stacking seat, so that the spring can avoid the accommodating space to avoid the spring affecting the silicon steel sheet falling in the accommodating space, thereby ensuring the stacking efficiency of the silicon steel sheet. In addition, since the spring is sleeved outside the stacking seat, the stacking seat can also guide the deformation of the spring to increase the stability of the spring when it is deformed.

[0026] Optionally, the lower mold has a mounting seat, the stacking seat is passed through the mounting seat, the mounting seat includes a main body and a ring body arranged inside one end of the bottom of the main body, the arc groove is arranged on the ring body, and the stacking seat has an edge that can cooperate with the top stop of the main body.

[0027] By adopting the above technical scheme, since the lower mold has a mounting seat and the stacking seat is inserted into the mounting seat, the difficulty of installing the stacking seat can be reduced, so as to improve the assembly efficiency of the stator and rotor production and processing device; and since the arc groove is provided in the ring body, the stacking seat can be completely hidden in the lower mold, and the size of the lower mold is reduced, so as to facilitate the miniaturization design of the stator and rotor production and processing device; the stacking seat has an edge that can cooperate with the top stop of the main body, so that the cooperation between the edge and the mounting seat can support the stacking seat, so as to increase the stability of the stacking seat; in addition, since the arc groove is provided in the ring body, the follower member can slide in a relatively large range, so as to further shorten the distance required for the silicon steel sheet to be placed in the accommodating space to move, so as to further ensure the production quality of the stator and rotor.

[0028] Optionally, the driving assembly includes an outer gear ring disposed at the bottom of the stacking seat, a driving gear meshingly connected to the outer gear ring, and a driving member for driving the driving gear to rotate.

[0029] By adopting the above technical solution, when driving the stacking seat, the driving member is started, and the driving member drives the driving gear, and then the driving gear drives the outer gear ring to rotate, and the outer gear ring drives the stacking seat to rotate, so as to realize driving the stacking seat to rotate.

At the same time, due to the setting of the elastic column, the pressure member can apply elastic pressure to the silicon steel sheet, so that the pressure member can self-adjust to avoid the phenomenon that the pressure applied by the pressure member to the silicon steel sheet is too large and causes the silicon steel sheet to deform, so as to ensure the production quality of the stator and rotor.

[0054] Reference Figures 1 to 12, discloses a stator and rotor production and processing device, which includes a lower die 1 and an upper die, wherein the lower die 1 has a rotor stamping station 11, a rotor stacking station 12 located behind the rotor stamping station 11, a stator stamping station 13 located behind the rotor stacking station 12, and a stator stacking station 14 located behind the stator stamping station 13; the upper die is located above the lower die 1 and can move in a direction close to or away from the lower die 1, and the upper die is provided with a rotor stamping die head 21 corresponding to the rotor stamping station 11, and a rotor stacking station 14 corresponding to the stator stamping station 13. The stacking station 12 is provided with a rotor pressure structure 22, the corresponding stator stamping station 13 is provided with a stator stamping die 23, and the corresponding stator stacking station 14 is provided with a stator pressure structure 24; when the upper mold moves toward the lower mold 1, the rotor stamping die 21 and the stator stamping die 23 stamp the material strip, and the rotor pressure structure 22 is used to apply downward pressure to the silicon steel sheets located at the rotor stacking station 12, and the stator pressure structure 24 is used to apply downward pressure to the silicon steel sheets located at the stator stacking station 14.

[0055] When producing the stator and rotor, the material strip is extended from one end of the stator and rotor production and processing device into between the upper die and the lower die 1, and then the upper die moves in the direction close to the lower die 1, and then the rotor stamping die 21 punches the material strip to form a silicon steel sheet for the rotor in a partial area of ​​the material strip, and then the upper die moves in the direction away from the lower die 1, and the formed silicon steel sheet for the rotor is placed in the rotor stacking position under the action of the manipulator, and the material strip continues to move so that the material strip with the rotor part punched out moves to the stator stamping station 13, and the upper die moves in the direction of the lower die 1, so that the stator stamping die 23 punches the material strip to form a silicon steel sheet for the stator in a partial area of ​​the material strip, and then the upper die moves in the direction away from the lower die 1, and the formed silicon steel sheet for the stator is placed in the stator stacking position under the action of the manipulator, and then the above steps are cycled to obtain a plurality of silicon steel sheets for the rotor and the stator.

[0056] When the upper die moves toward the direction approaching the lower die 1, the rotor pressure structure 22 applies downward pressure to the silicon steel sheets in the rotor stacking station 12, and the stator pressure structure 24 applies downward pressure to the silicon steel sheets in the stator stacking station 14, so that two adjacent silicon steel sheets are tightly attached to eliminate the gap between the two adjacent silicon steel sheets, while avoiding the offset of the silicon steel sheets, thereby avoiding the uneven thickness of the stator and rotor, and further improving the production quality of the stator and rotor.

[0057] The present application does not specifically limit the number of the rotor stamping stations 11 and the stator stamping stations 13. Preferably, refer to Figure 1 and Figure 2, multiple rotor stamping stations 11 and stator stamping stations 13 are provided, multiple rotor stamping dies 21 are provided corresponding to the rotor stamping stations 11, and multiple stator stamping dies 23 are provided corresponding to the stator stamping stations 13, so that the rotor and the stator are formed by multiple stamping to reduce the stress concentration of the material strip, thereby ensuring the flatness of the silicon steel sheets used for the rotor and the silicon steel sheets used for the stator. Of course, in other embodiments, only one rotor stamping station 11 and one stator stamping station 13 can be provided.

[0058] The present application does not specifically limit the structures of the rotor pressure structure 22 and the stator pressure structure 24. Preferably, refer to Figure 3 and Figure 4 The rotor pressure structure 22 and the stator pressure structure 24 both include an elastic column 221, which has a connecting end connected to the upper mold and a pressure end opposite to the connecting end, and the pressure end is provided with a pressure member 222 that can contact the silicon steel sheet.

[0059] When the upper mold moves downward, the upper mold drives the elastic column 221 to move downward, and then the elastic column 221 drives the pressure member 222 to move downward, so that the pressure member 222 contacts the silicon steel sheet and presses the silicon steel sheet downward, thereby overcoming the bias of the silicon steel sheet so that two adjacent silicon steel sheets are tightly attached to avoid uneven thickness of the stator and rotor. At the same time, due to the setting of the elastic column 221, the pressure member 222 can apply elastic pressure to the silicon steel sheet, so that the pressure member 222 can self-adjust to avoid the pressure applied by the pressure member 222 on the silicon steel sheet is too large and causes deformation of the silicon steel sheet, so as to ensure the production quality of the stator and rotor.

[0060] The present application does not specifically limit the structure of the elastic column 221. Preferably, refer to Figure 3 and Figure 4 The elastic column 221 includes a first rod body 223 having a receiving cavity, a second rod body 224 passing through the receiving cavity, and an elastic portion 225 disposed in the receiving cavity and acting on the second rod body 224 . The pressure member 222 is connected to one end of the bottom of the second rod body 224 .

[0061] When the upper mold moves toward the direction close to the lower mold 1, the upper mold drives the first rod 223 to move, and then the first rod 223 drives the second rod 224 to move toward the direction close to the lower mold 1, so that the pressure member 222 contacts the silicon steel sheet, and then the upper mold continues to move toward the direction close to the lower mold 1. At this time, the second rod 224 remains relatively stationary under the action of the silicon steel sheet, and the second rod 224 applies pressure to the elastic part 225 in the direction away from the lower mold 1. The elastic part 225 is deformed and applies a reverse force to the second rod 224, so that the pressure applied by the pressure member 222 on the silicon steel sheet is maintained within a reasonable range. On the one hand, the pressure effect on the silicon steel sheet is guaranteed, and on the other hand, the deformation of the silicon steel sheet is avoided to ensure the production quality of the stator and rotor.

[0062] The present application does not specifically limit the structure of the elastic part 225. Preferably, the elastic part 225 is a spring disposed in the accommodating cavity to ensure the elastic support effect on the second rod body 224, thereby improving the pressure effect on the silicon steel sheet.

[0063] Further, see Figure 3 and Figure 4 The elastic column 221 also includes a limiting rod 226 passing through the second rod body 224, and a limiting groove 227 for accommodating the limiting rod 226 is provided on the side of the first rod body 223, and the limiting groove 227 is arc-shaped.

[0064] Since the limiting rod 226 is penetrated by the second rod body 224, the side of the first rod body 223 is provided with a limiting groove 227 for accommodating the limiting rod 226, so that the cooperation between the limiting rod 226 and the limiting groove 227 can limit the second rod body 224 to avoid the separation of the second rod body 224 from the first rod body 223, thereby increasing the connection stability between the second rod body 224 and the first rod body 223; and since the limiting groove 227 is arc-shaped, when the second rod body 224 and the first rod body 223 slide relative to each other, the second rod body 224 can rotate around its own axis under the cooperation of the limiting rod 226 and the limiting groove 227, so that the pressure member 222 can apply a rotational force to the silicon steel sheet to overcome the thickness difference caused by the silicon steel sheet for the rotor and the silicon steel sheet for the stator being formed by stamping, thereby making the thickness of the stator and rotor more uniform, so as to further improve the production quality of the stator and rotor.

[0065] In other embodiments, the elastic column 221 may also be a rod-shaped structure made of elastic material, such as rubber and the like.

[0066] In other embodiments, the rotor pressure structure 22 and the stator pressure structure 24 may both be structures without elasticity, such as pressure rods.

[0067] In a preferred embodiment, referring to Figures 5 to 9The rotor stacking station 12 and the stator stacking station 14 are both provided with a stacking mold 3, and the stacking mold 3 includes a stacking seat 31, a follower member 32 and a driving assembly 33. The stacking seat 31 has an accommodating space that penetrates itself in its own axial direction, and the stacking seat 31 is penetrated by the lower mold 1, the follower member 32 is connected to the lower mold 1, and one end of the follower member 32 extends into the accommodating space, and the driving assembly 33 is used to drive the stacking seat 31 to rotate, and when the stacking seat 31 and the lower mold 1 rotate relative to each other, the follower member 32 moves toward the outside of the stacking seat 31.

[0068] After the manipulator places the silicon steel sheets in the accommodating space, the follower component 32 blocks the silicon steel sheets at the bottom layer so that the silicon steel sheets can stay stably in the accommodating space, so that multiple silicon steel sheets can be stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or a silicon steel sheet is placed in the accommodating space, the driving component 33 drives the stacking seat 31, thereby causing the stacking seat 31 and the lower mold 1 to rotate relative to each other at a certain angle. At this time, the silicon steel sheets that are in contact with the inner wall of the accommodating space slide relative to the inner wall of the accommodating space under the rotation of the stacking seat 31, so that the two adjacent silicon steel sheets are completely fitted together, and the influence of the uneven thickness of the workpiece caused by the stamping of the silicon steel sheets on the overall thickness of the stator and rotor is avoided, thereby ensuring the uniformity of the thickness of the stator and rotor, and further ensuring the production quality of the stator and rotor.

[0069] In addition, when the stacking seat 31 and the lower mold 1 rotate relative to each other, the follower member moves toward the outside of the stacking seat 31 under the action of the lower mold 1 and the stacking seat 31, so that after the silicon steel sheets are stacked to the required number, the follower member 32 moves to the outside of the silicon steel sheets, so that the follower member 32 and the bottom of the silicon steel sheets form a avoidance, so that the stacked silicon steel sheets fall through the bottom opening of the accommodating space to achieve the release of the stacked silicon steel sheets, so that the staff can carry out the next step of processing on the stacked silicon steel sheets, thereby greatly improving the production efficiency of the stator and rotor.

[0070] In a preferred embodiment, referring to Figure 6 , Figure 8 and Fig. 9 The follower member 32 has a connecting section 321 and a stop section 322. The stop section 322 is penetrated through the stacking seat 31. The lower mold 1 has an arc groove 421 extending along the circumference of the stacking seat 31. The distance between the arc groove 421 and the accommodating space gradually increases along the circumference of the stacking seat 31. The connecting section 321 is penetrated through the arc groove 421.

[0071] Since the distance between the arc groove 421 and the accommodating space gradually increases along the circumference of the stacking seat 31, and the connecting section 321 is penetrated in the arc groove 421, when the stacking seat 31 and the lower mold 1 rotate relative to each other, the follower member 32 can rotate along with the stacking seat 31 under the action of the stop section 322, so that the connecting section 321 of the follower member 32 and the arc groove 421 slide relative to each other, so that the follower member 32 moves toward the outside of the stacking seat 31 under the relative rotation of the stacking seat 31 and the lower mold 1, so that as the number of stacked silicon steel sheets increases, the stop matching area between the stop section 322 and the silicon steel sheet becomes smaller and smaller, and finally, after the silicon steel sheets are stacked to the required number, the stop section 322 releases the stop matching with the silicon steel sheet, so that the stacked silicon steel sheets fall through the bottom opening of the accommodating space. In addition, the groove wall of the arc groove 421 can also limit the follower member 32 to prevent the follower member 32 from rotating under the gravity of the silicon steel sheet, thereby increasing the support stability of the follower member 32 on the silicon steel sheet.

[0072] Preferably, the stopping section 322 and the connecting section 321 are arranged perpendicularly, so that the follower member 32 is L-shaped to increase the stopping effect on the silicon steel sheet.

[0073] If the distance between the arc groove 421 and the inner wall of the accommodating space gradually increases in the clockwise direction, when the stacking seat 31 rotates clockwise under the action of the driving assembly 33, the follower member 32 moves toward the outside of the stacking seat 31 under the action of the stacking mold 3 and the lower mold 1; if the distance between the arc groove 421 and the inner wall of the accommodating space gradually increases in the counterclockwise direction, when the stacking seat 31 rotates counterclockwise under the action of the driving assembly 33, the follower member 32 moves toward the outside of the stacking seat 31 under the action of the stacking mold 3 and the lower mold 1.

[0074] Further, see Figure 6 , Figure 8 and Fig. 9 The arc groove 421 penetrates the lower mold 1 in the axial direction, the stacking seat 31 is provided with a through hole 311, the stop section 322 is penetrated by the through hole 311, and the stacking seat 31 is provided with an elastic member 313 acting on the stop section 322, and the elastic member 313 can apply an upward elastic force to the stop section 322.

[0075] Since the arc groove 421 penetrates the lower mold 1 in the axial direction, and the stacking seat 31 is provided with a through hole 311, the stop segment 322 is penetrated by the through hole 311, and the stacking seat 31 is provided with an elastic member 313 acting on the stop segment 322, so that the stop segment 322 can elastically move in the axial direction of the stacking seat 31 following the change in the number of silicon steel sheets. On the one hand, when the silicon steel sheets are placed in the accommodating space, the required movement distance of the silicon steel sheets to be placed is reduced, so as to reduce the possibility that the silicon steel sheets may contact the inner wall of the accommodating space and become offset, thereby further ensuring the uniformity of the thickness of the stator and rotor. On the other hand, as the number of silicon steel sheets placed above the stop segment 322 gradually increases, the stop segment 322 elastically moves downward to ensure that the required number of silicon steel sheets can be placed in the accommodating space, so as to ensure the production quality of the stator and rotor.

[0076] The present application does not specifically limit the structure of the elastic member 313, and the elastic member 313 may adopt any one of the following embodiments:

[0077] Embodiment 1, in this embodiment, refer to Figure 6 The elastic member 313 is a spring sleeved on the outside of the stacking seat 31. The stacking seat 31 has a supporting portion 318. The supporting portion 318 is located at the bottom of the spring to support the spring.

[0078] Since the support portion 318 is located at the bottom of the spring, the support portion 318 can support the spring to increase the elastic support effect of the spring on the stop section 322, and the spring is sleeved outside the stacking seat 31, so that the spring can avoid the accommodating space to avoid the spring affecting the silicon steel sheet falling in the accommodating space, thereby ensuring the stacking efficiency of the silicon steel sheet. In addition, since the spring is sleeved outside the stacking seat 31, the stacking seat 31 can also guide the deformation of the spring to increase the stability of the spring when it is deformed.

[0079] The present application does not specifically limit the structure of the support portion 318. Preferably, the support portion 318 is an annular structure extending along the circumference of the stacking seat 31 to increase the support points for the spring, thereby increasing the stability of the spring. In other implementation examples, the support portion 318 can also be a block structure arranged at intervals along the circumference of the stacking seat 31.

[0080] Embodiment 2, in this embodiment, refer to Figure 8 and Fig. 9 The elastic member 313 is a spring disposed in the through opening 311 , a bottom end of the spring contacts the wall of the through opening 311 , and a top end of the spring contacts the bottom of the stop section 322 .

[0081] Since the elastic member 313 is a spring arranged in the through port 311, the elastic member 313 can form an avoidance with the outer peripheral surface of the stacking seat 31, so as to avoid the phenomenon that the spring is arranged outside the stacking seat 31 and puts forward higher requirements on the gap between the stacking seat 31 and the lower mold 1, so as to reduce the difficulty of assembling the stacking seat 31 and further improve the assembly efficiency of the stator and rotor production and processing device.

[0082] In this embodiment, there is no specific limitation on the installation method of the spring, and any one of the following implementation examples may be used:

[0083] Implementation Example 1: In this implementation example, refer to Figure 8 A positioning column 312 is provided through the wall of the opening 311 , and the spring is sleeved on the positioning column 312 .

[0084] Specifically, the positioning column 312 is disposed on the bottom wall of the through hole 311 , the bottom end of the spring is sleeved on the outside of the positioning column 312 , and the inner circumference of the bottom end of the spring is interference fit with the positioning column 312 .

[0085] Since the spring is sleeved on the positioning column 312, the positioning column 312 can position the spring to avoid the spring from being separated from the positioning column 312, thereby increasing the connection stability between the spring and the through port 311 and reducing the difficulty of installing the spring, thereby further improving the assembly efficiency of the stacked mold 3.

[0086] Implementation Example 2: In this implementation example, refer to Fig. 9 A low resistance sheet 314 located at the bottom of the stop section 322 is provided at the top of the spring, the low resistance sheet 314 is provided with a guide column 315 penetrating the spring, and the stacking seat 31 is provided with a guide hole 316 for accommodating the guide column 315 .

[0087] Since the top of the spring is provided with a low-resistance sheet 314 located at the bottom of the stop section 322, on the one hand, the spring is in contact with the stop section 322 through the low-resistance sheet 314 to reduce the friction between the spring and the stop section 322 to ensure the smooth movement of the follower member 32 toward the outside of the stacking seat 31, and on the other hand, the force on the top end of the spring is more balanced to avoid the spring from escaping from the side of the through hole 311, thereby increasing the stability of the spring; and the low-resistance sheet 314 is provided with a guide column 315, and the stacking seat 31 is provided with a guide hole 316 for accommodating the guide column 315, so that when the spring moves downward under the pressure of the stop section 322, the guide column 315 and the guide hole 316 slide relative to each other, on the one hand, the guide column 315 can guide the deformation direction of the spring to increase the stability of the spring when it is deformed, thereby ensuring the elastic support effect on the stop section 322, and on the other hand, it can also increase the connection stability between the spring and the stacking seat 31.

[0088] The present application does not specifically limit the connection method between the guide post 315 and the low resistance sheet 314. Preferably, the guide post 315 is fixedly connected to the low resistance sheet 314 to increase the connection stability between the guide post 315 and the low resistance sheet 314. In other implementation examples, the guide post 315 can also be threadedly connected to the low resistance sheet 314.

[0089] In other embodiments, the elastic member 313 may also be an elastic sheet or other elastic structures.

The stacking seat 31 has an edge 317 that can cooperate with the top stop of the main body 41.

[0091] Since the lower mold 1 has a mounting seat 4 and the stacking seat 31 is passed through the mounting seat 4, the difficulty of installing the stacking seat 31 can be reduced, so as to improve the assembly efficiency of the stator and rotor production and processing device; and since the arc groove 421 is provided in the ring body 42, the stacking seat 31 can be completely hidden in the lower mold 1, and the size of the lower mold 1 is reduced, so as to facilitate the miniaturization design of the stator and rotor production and processing device; the stacking seat 31 has an edge 317 that can cooperate with the top stop of the main body 41, so that the cooperation between the edge 317 and the mounting seat 4 can support the stacking seat 31 to increase the stability of the stacking seat 31; in addition, since the arc groove 421 is provided in the ring body 42, the follower member 32 can slide within a relatively large range to further shorten the distance required for the silicon steel sheet to be placed in the accommodating space to move, so as to further ensure the production quality of the stator and rotor.

Preferably, refer to Figure 5 and Figure 6 The driving assembly 33 includes an outer gear ring 331 disposed at the bottom of the stacking seat 31, a driving gear 332 meshing and drivingly connected to the outer gear ring 331, and a driving member for driving the driving gear 332 to rotate.

[0096] The present application does not specifically limit the transmission connection mode between the servo motor and the driving gear 332. Preferably, the output shaft of the servo motor is provided with a gear meshing with the driving gear 332 for transmission connection, so as to realize the transmission connection between the servo motor and the driving gear 332 and reduce the height of the driving assembly 33. In other implementation examples, the output shaft of the servo motor is transmission-connected to the rotating shaft through a coupling.

[0099] Preferably, the present application uses anaerobic adhesive to connect two adjacent silicon steel sheets, and then when the stator pressure structure 24 applies pressure to the silicon steel sheets constituting the stator, the air between the two adjacent stators can be discharged under the action of the stator pressure structure 24, so that the anaerobic adhesive solidifies quickly and fixes the two adjacent silicon steel sheets together, so as to speed up the production efficiency of the stator and ensure the production quality of the stator.

[0100] The present application does not specifically limit the structure of the dispensing module 5. Preferably, refer to Fig.10 , Fig.11 and Fig.12 The glue dispensing module 5 includes a connecting seat 51 with a center hole, a glue coating plate 52 arranged in the center hole, and a power member 53 arranged in the connecting seat 51 for driving the glue coating plate 52 to move.

The power member 53 is used to drive the glue coating plate 52 to move axially along the center hole, so that the glue coating plate 52 has a glue coating position with the top flush with the top of the connecting seat 51 and an avoidance position with the top recessed in the top of the connecting seat 51.

[0101] It can be understood that the connecting seat 51 is installed on the lower mold 1, and the top end face of the connecting seat 51 is flush with the end face of the lower mold 1; the glue outlet hole 521 penetrates the glue coating plate 52 in the thickness direction of the glue coating plate 52, and the pipeline for conveying the glue is connected to the bottom hole of the glue outlet hole 521, so that the glue passes through the glue coating plate 52 and then flows out through the top hole of the glue outlet hole 521.

[0102] When the robot clamps the silicon steel sheet located at the bottom layer, the power part 53 drives the glue coating plate 52, and then the glue coating plate 52 moves downward along the axial direction of the center hole, so that the glue coating plate 52 moves from the glue coating position to the avoidance position, so that the glue coating plate 52 and the top end face of the mounting seat 4 are avoided, that is, the glue coating plate 52 and the silicon steel sheet are avoided, so as to avoid the contact between the colloid discharged through the glue outlet hole 521 and the silicon steel sheet; when the robot clamps the silicon steel sheet located at the non-bottom layer, the power part 53 drives the glue coating plate 52, and then the glue coating plate 52 moves upward along the axial direction of the mounting hole, so that the glue coating plate 52 moves from the avoidance position to the glue coating position, so that after the robot moves the silicon steel sheet to the glue dispensing station 15, the colloid flowing out through the glue outlet hole 521 can adhere to the silicon steel sheet, so as to achieve the gluing of the silicon steel sheet.

[0104] In a preferred embodiment, the center hole has a stop wall. When the glue coating plate 52 is in the glue coating position, the glue coating plate 52 and the stop wall cooperate in the axial direction of the center hole, thereby increasing the stability of the glue coating plate 52 in the glue coating position and preventing the glue coating plate 52 from protruding from the top end surface of the connecting seat 51 due to transitional movement.

[0106] Further, see Fig.11 and Fig.12 A reset member 512 acting on the glue coating plate 52 is provided in the connecting seat 51. When the glue coating plate 52 is in the avoidance position, the reset member 512 is deformed and applies a force to the glue coating plate 52 to move toward the gluing position. Then, when the glue coating plate 52 is in the gluing position, the reset member 512 can support the glue coating plate 52 to increase the supporting point of the glue coating plate 52, thereby increasing the stability of the glue coating plate 52 in the gluing position, and at the same time can also reduce the load of the power member 53 when supporting the glue coating plate 52 in the gluing position.
