Description

Technical Field

[0001] This application belongs to the technical field of stator and rotor manufacturing, specifically relating to a stator and rotor manufacturing and processing device and its usage method. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It is widely used in various equipment and systems. The composition of an electric motor is relatively complex, but it mainly consists of a stator and a rotor. The stator and rotor work together through the action of magnetic coils to convert electromagnetic energy into mechanical energy.

[0003] Currently, both the stator and rotor are made of a certain number of silicon steel sheets of the same shape. Adjacent silicon steel sheets are usually connected by welding, which increases the eddy current loss of the stator. In addition, after the silicon steel sheets are connected by welding, the weld points need to be reprocessed, which affects the production efficiency of the stator.

[0004] To reduce stator eddy current losses and improve stator production efficiency, our company has proposed using adhesive bonding to fix silicon steel sheets. This method can significantly reduce stator eddy current losses and avoid the need for reprocessing of the solder joints, thereby improving stator production efficiency.

[0005] To accommodate stator production using adhesive bonding, our company designed a stator and rotor manufacturing and processing device, which includes a lower mold and an upper mold. The upper mold is located above the lower mold and can move towards or away from the lower mold. The lower mold has a rotor stamping station, a rotor stacking station, a stator stamping station, a glue dispensing station, and a stator stacking station. The glue dispensing station is equipped with a glue dispensing module, which can realize the stamping and forming of silicon steel sheets for stator and rotor and the glue dispensing of silicon steel sheets for stator, thereby fixing the silicon steel sheets of stator together by adhesive bonding. However, in order to simplify the control program of the stator and rotor manufacturing and processing device, the robot arm needs to stop at the glue dispensing station after clamping each silicon steel sheet, and then move the glued silicon steel sheet to the stator stacking station. However, since the silicon steel sheet at the bottom layer does not need to be glued, how to avoid the silicon steel sheet by the glue dispensing module has become an urgent technical problem to be solved.

[0006] In addition, gaps may exist between multiple silicon steel sheets located in the stacking station, or the silicon steel sheets may be misaligned, which may lead to uneven thickness of the stator and rotor after forming, thus affecting the production quality of the stator and rotor. Summary of the Invention

[0007] This application provides a stator and rotor manufacturing and processing apparatus and a method of using it to solve at least one of the above-mentioned technical problems.

[0008] The technical solution adopted in this application is as follows:

[0009] A stator and rotor manufacturing and processing apparatus, comprising:

[0010] The lower mold has a rotor stamping station, a rotor stacking station located behind the rotor stamping station, a stator stamping station located behind the rotor stacking station, a glue dispensing station located behind the stator stamping station, and a stator stacking station located behind the glue dispensing station.

[0011] The upper mold is located above the lower mold and can move in a direction close to or away from the lower mold. The upper mold is provided with a rotor stamping die head corresponding to the rotor stamping station, a rotor compaction structure corresponding to the rotor stacking station, a stator stamping die head corresponding to the stator stamping station, a dispensing module corresponding to the dispensing station, and a stator compaction structure corresponding to the stator stacking station.

[0012] When the upper die moves toward the lower die, the rotor stamping die head and the stator stamping die head stamp the strip, and the rotor compaction structure is used to apply downward pressure to the silicon steel sheet located at the rotor stacking station, and the stator compaction structure is used to apply downward pressure to the silicon steel sheet located at the stator stacking station.

[0013] The dispensing module includes a connector and a coating plate with a dispensing hole. The connector has a central hole, the coating plate passes through the central hole, and the coating plate can move relative to the connector so that the coating plate has a coating position where the top of the coating plate is flush with the top of the connector and a position where the top of the coating plate is recessed into the top end face of the connector to avoid contact.

[0014] By adopting the above technical solution, during the production of stator and rotor, the material strip is inserted from one end of the stator and rotor production processing device between the upper and lower dies. The upper die then moves towards the lower die, causing the rotor stamping die to stamp the material strip, forming rotor silicon steel sheets in a portion of the strip. The upper die then moves away from the lower die, and the formed rotor silicon steel sheets are placed in the rotor stacking position under the action of a robotic arm. The material strip continues to move, allowing the strip with the rotor portion punched out to move to the stator stamping station. The upper die then moves towards the lower die, thereby... The stator stamping die presses the strip to form a portion of the strip into stator silicon steel sheets. Then, the upper die moves away from the lower die, and the formed stator silicon steel sheets are placed at the dispensing station by a robot. At this time, the glue applicator is in a clearance position to prevent the bottom stator silicon steel sheets from being coated with glue. The robot then places the stator silicon steel sheets in the stator stacking position. The above steps are repeated to obtain multiple rotor silicon steel sheets and stator silicon steel sheets, and adjacent stator silicon steel sheets are fixedly connected by glue.

[0015] As the upper die moves toward the lower die, the rotor compaction structure applies downward pressure to the silicon steel sheets located in the rotor stacking station, and the stator compaction structure applies downward pressure to the silicon steel sheets located in the stator stacking station. This causes adjacent silicon steel sheets to fit tightly together, eliminating gaps between adjacent silicon steel sheets and preventing the silicon steel sheets from being misaligned. This avoids uneven thickness of the stator and rotor, thereby improving the production quality of the stator and rotor.

[0016] Optionally, the connecting seat includes a base plate, a top cover, and a connecting post for connecting the base plate and the top cover. The base plate is provided with a guide sleeve, and the adhesive plate is provided with a guide post passing through the guide sleeve.

[0017] By adopting the above technical solution, since the connecting seat includes a base plate, a top cover, and a connecting post for connecting the base plate and the top cover, the assembly difficulty of the dispensing plate can be reduced, thereby improving the assembly efficiency of the dispensing module. Furthermore, the base plate is provided with a guide sleeve, and the dispensing plate is provided with a guide post passing through the guide sleeve. Thus, when the dispensing plate moves, the dispensing plate drives the guide post to move, causing the guide post and the guide sleeve to slide relative to each other. This sliding cooperation between the guide post and the guide sleeve guides the movement of the dispensing plate, thereby increasing the stability of the dispensing plate during movement.

[0018] Optionally, an elastic element is provided on the outside of the guide post, with one bottom end of the elastic element abutting against the guide sleeve and one top end of the elastic element abutting against the adhesive plate to apply an upward elastic force to the adhesive plate.

[0019] By adopting the above technical solution, since the bottom end of the elastic element abuts against the guide sleeve and the top end of the elastic element abuts against the coating plate, the elastic element can apply an upward elastic force to the coating plate, so that when the coating plate is in the coating position, the elastic element can support the coating plate, thereby increasing the number of support points for the coating plate and thus increasing the stability of the coating plate when it is in the coating position. At the same time, the guide post can also guide the deformation direction of the elastic element to increase the stability of the elastic element.

[0020] Optionally, the dispensing module further includes a driving component disposed on the base plate, the telescopic end of the driving component being connected to the dispensing plate to move the dispensing plate between the dispensing position and the avoidance position.

[0021] By adopting the above technical solution, since the telescopic end of the driving component is connected to the coating plate, the driving component can drive the coating plate, thereby enabling the coating plate to move automatically between the coating position and the avoidance position, so as to improve the response efficiency of the coating plate when moving between the coating position and the avoidance position, and thus improve the production efficiency of the stator and rotor.

[0022] Optionally, the upper cover has a stop wall, and when the glue-applying plate is in the glue-applying position, the glue-applying plate and the stop wall engage in a stop-fitting action in the upward direction.

[0023] By adopting the above technical solution, when the coating plate is in the coating position, the coating plate and the stop wall stop and cooperate in the upward direction, thereby increasing the stability of the coating plate in the coating position, so as to ensure the coating effect on the silicon steel sheet.

[0024] Optionally, both the rotor compaction structure and the stator compaction structure include an elastic column and a compaction member. The elastic column has a connecting end connected to the upper mold and a pressure-applying end opposite to the connecting end, and the compaction member is disposed at the pressure-applying end.

[0025] By adopting the above technical solution, when the upper mold moves downward, it drives the elastic column downward, which in turn drives the compaction component downward, so that the compaction component comes into contact with the silicon steel sheet and applies downward pressure to the silicon steel sheet. This overcomes the offset of the silicon steel sheet and makes two adjacent silicon steel sheets fit tightly together, thus avoiding the phenomenon of uneven thickness of the stator and rotor. At the same time, due to the setting of the elastic column, the compaction component can apply elastic pressure to the silicon steel sheet, so that the compaction component can self-adjust and avoid the phenomenon of deformation of the silicon steel sheet due to excessive pressure applied by the compaction component, thereby ensuring the production quality of the stator and rotor.

[0026] Optionally, the elastic column includes a first rod having a receiving cavity, a second rod passing through the receiving cavity, and an elastic part disposed in the receiving cavity and acting on the second rod, wherein the compaction member is disposed at the end of the second rod away from the first rod.

[0027] By adopting the above technical solution, when the upper mold moves towards the direction closer to the lower mold, the upper mold drives the first rod to move, which in turn drives the second rod to move towards the direction closer to the lower mold, so that the compaction component comes into contact with the silicon steel sheet. Then the upper mold continues to move towards the direction closer to the lower mold. At this time, the second rod remains relatively stationary under the action of the silicon steel sheet. The second rod applies pressure to the elastic part away from the direction of the lower mold. The elastic part deforms and applies a reverse force to the second rod, so that the pressure applied by the compaction component to the silicon steel sheet is kept 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.

[0028] Optionally, a limiting groove is provided on the side of the first rod, and the elastic column further includes a limiting rod passing through the second rod and the limiting groove, wherein the limiting groove is arc-shaped.

[0029] By adopting the above technical solution, since the limiting rod passes through the second rod and the limiting groove, the cooperation between the limiting rod and the limiting groove can limit the second rod to prevent the second rod from separating from the first rod, thereby increasing the connection stability between the second rod and the first rod. Furthermore, since the limiting groove is arc-shaped, when the second rod and the first rod slide relative to each other, the second rod can rotate around its own axis under the cooperation of the limiting rod and the limiting groove, so that the compaction component can apply rotational force to the silicon steel sheet to overcome the thickness difference caused by the stamping of the silicon steel sheet for the rotor and the silicon steel sheet for the stator, thereby making the thickness of the stator and rotor more uniform and further improving the production quality of the stator and rotor.

[0030] Optionally, both the rotor stacking station and the stator stacking station are provided with a stacking mold. The stacking mold includes a stacking base, a follower component, and a driving assembly. The stacking base has an accommodating space that extends through itself in its own axial direction, and the stacking base passes through the lower mold. The follower component is connected to the lower mold, and one end of the follower component extends into the accommodating space. The driving assembly is used to drive the stacking base to rotate, and when the stacking base rotates relative to the lower mold, the follower component moves toward the outside of the stacking base.

[0031] By adopting the above technical solution, after the robotic arm places the silicon steel sheets into the accommodating space, the follower component blocks the silicon steel sheet located at the bottom layer, so that the silicon steel sheet remains stably in the accommodating space, allowing multiple silicon steel sheets to be stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or after one silicon steel sheet is placed in the accommodating space, the drive component drives the stacking seat, which then rotates the stacking seat relative to the lower mold 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, so that two adjacent silicon steel sheets are completely attached. This avoids the influence of uneven workpiece thickness caused by the stamping of silicon steel sheets on the overall thickness of the stator and rotor, thereby ensuring the uniformity of the stator and rotor thickness and thus ensuring the production quality of the stator and rotor.

[0032] In addition, when the stacking base and the lower die rotate relative to each other, the follower component moves outward of the stacking base under the action of the lower die and the stacking base. After the silicon steel sheets are stacked to the required number, the follower component moves to the outside of the silicon steel sheets, so that the follower component and the bottom of the silicon steel sheets can avoid each other. This allows the stacked silicon steel sheets to fall through the bottom opening of the accommodating space, thereby releasing the stacked silicon steel sheets so that the workers can carry out the next step of processing. This greatly improves the production efficiency of the stator and rotor.

[0033] This application also discloses a method for using a stator and rotor manufacturing and processing apparatus to improve the production efficiency of stators and rotors.

[0034] A method of using a stator and rotor manufacturing and processing apparatus, comprising the following steps:

[0035] S1. Loading: Insert one end of the strip into the space between the upper and lower dies, ensuring that the beginning of the strip completely covers the top of the rotor stamping station.

[0036] S2, stamping: the upper die moves toward the direction closer to the lower die so that the rotor stamping die head stamps the strip. The part of the strip opposite to the rotor stamping station forms a silicon steel sheet for the rotor. Then the upper die moves away from the lower die to reset.

[0037] S3, Stacking: The robotic arm places the formed rotors into the rotor stacking station using silicon steel sheets;

[0038] S4. Pushing the material strip: Continue to push the strip between the upper and lower dies so that the unpressed part of the strip moves to the rotor stamping station, while the part of the strip with the silicon steel sheet for the rotor punched off moves to the stator stamping station.

[0039] S5. Stamping again, the upper die moves toward the direction closer to the lower die, the rotor stamping die head stamps the strip, the stator stamping die head stamps the strip, the part of the strip opposite to the rotor stamping station forms a silicon steel sheet for the rotor, the part of the strip opposite to the stator stamping station forms a silicon steel sheet for the stator, and then the upper die moves toward the direction away from the lower die to reset.

[0040] S6. Stacking and dispensing: The robot places the formed rotor silicon steel sheet at the rotor stacking station, the robot places the formed stator silicon steel sheet at the dispensing station, and then the robot places the stator silicon steel sheet that has passed through the dispensing station at the stator stacking station.

[0041] During the S7 and S4-S6 cycles, as the upper die moves toward the lower die, the rotor compaction structure applies downward pressure to the silicon steel sheet located at the rotor stacking station, and the stator compaction structure applies downward pressure to the silicon steel sheet located at the stator stacking station.

[0042] By adopting the above technical solution and using the above method to produce stators and rotors, the steps required for stator and rotor production are simplified, thereby improving the production efficiency of stators and rotors.

[0043] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0044] 1. The stator and rotor manufacturing apparatus of this application includes a lower die and an upper die. The upper die has a rotor stamping station, a rotor stacking station, a stator stamping station, a glue dispensing station, and a stator stacking station. The upper die is located above the lower die and can move towards or away from the lower die. The upper die is equipped with a rotor stamping die head, a rotor compaction structure, a stator stamping die head, a glue dispensing module, and a stator compaction structure. When the upper die moves towards the lower die, the rotor stamping die head and the stator stamping die head stamp the strip material. The rotor compaction structure applies downward pressure to the silicon steel sheet located at the rotor stacking station, and the stator compaction structure applies downward pressure to the silicon steel sheet located at the stator stacking station. Glue dispensing... The module includes a connector and a coating plate with an adhesive outlet. The connector has a central hole through which the coating plate passes. The coating plate can move relative to the connector, so that the top of the coating plate is flush with the top of the connector and the top of the coating plate is recessed into the top end face of the connector to avoid gaps. This allows two adjacent stator silicon steel sheets to be fixedly connected by adhesive, and also avoids gaps between the coating plate and the bottom silicon steel sheet. It also ensures that two adjacent silicon steel sheets are in close contact, eliminating gaps between them and preventing the silicon steel sheets from being misaligned. This avoids uneven thickness of the stator and rotor, thereby improving the production quality of the stator and rotor.

[0045] 2. The connecting seat in this application includes a base plate, a top cover, and a connecting post for connecting the base plate and the top cover, thereby reducing the assembly difficulty of the dispensing plate and improving the assembly efficiency of the dispensing module. The base plate is provided with a guide sleeve, and the dispensing plate is provided with a guide post passing through the guide sleeve. When the dispensing plate moves, the dispensing plate drives the guide post to move, so that the guide post and the guide sleeve slide relative to each other. This sliding cooperation between the guide post and the guide sleeve guides the movement of the dispensing plate, thereby increasing the stability of the dispensing plate during movement.

[0046] 3. The guide post in this application is provided with an elastic element on its exterior. One end of the elastic element abuts against the guide sleeve, and one end of the elastic element abuts against the adhesive plate to apply an upward elastic force to the adhesive plate. This allows the elastic element to support the adhesive plate when it is in the adhesive application position, thereby increasing the number of support points for the adhesive plate and thus increasing the stability of the adhesive plate when it is in the adhesive application position. At the same time, the guide post can also guide the deformation direction of the elastic element to increase the stability of the elastic element. Attached Figure Description

[0063] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0065] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0066] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0067] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0068] Reference Figures 1 to 12A stator and rotor manufacturing apparatus is disclosed, comprising a lower die 1 and an upper die. 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, a dispensing station 14 located behind the stator stamping station 13, and a stator stacking station 15 located behind the dispensing station 14. 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. The upper die is provided with a rotor stamping die head 21 corresponding to the rotor stamping station 11, a rotor compaction structure 22 corresponding to the rotor stacking station 12, a stator stamping die head 23 corresponding to the stator stamping station 13, a dispensing module 24 corresponding to the dispensing station 14, and a stator compaction structure 25 corresponding to the stator stacking station 15. When the upper die moves toward the lower die 1, the rotor stamping die head 21 and the stator stamping die head 23 stamp the strip material. The rotor compaction structure 22 applies downward pressure to the silicon steel sheet located at the rotor stacking station 12, and the stator compaction structure 25 applies downward pressure to the silicon steel sheet located at the stator stacking station 15. The dispensing module 24 includes a connecting seat 241 and a dispensing plate 242 with a dispensing hole 249. The connecting seat 241 has a central hole, and the dispensing plate 242 passes through the central hole. The dispensing plate 242 can move relative to the connecting seat 241 so that the dispensing plate 242 has a dispensing position where its top is flush with the top of the connecting seat 241 and a position where its top is recessed into the top end face of the connecting seat 241 to avoid contact.

[0069] During the production of the stator and rotor, the strip material is inserted from one end of the stator and rotor production processing device between the upper die and the lower die 1. The upper die then moves towards the lower die 1, causing the rotor stamping die 21 to stamp the strip material, forming a portion of the strip into a rotor silicon steel sheet. The upper die then moves away from the lower die 1, and the formed rotor silicon steel sheet is placed in the rotor stacking position by a robotic arm. The strip material continues to move, allowing the strip with the rotor portion punched out to reach the stator stamping station 13. The upper die moves towards the lower die 1, thus causing the stator stamping die... The head 23 punches the strip to form a stator silicon steel sheet in a portion of the strip. Then, the upper die moves away from the lower die 1, and the formed stator silicon steel sheet is placed at the dispensing station 14 by the robot. At this time, the glue plate 242 is in a clearance position to prevent the bottom stator silicon steel sheet from being coated with glue. Then, the robot places the stator silicon steel sheet in the stator stacking position. The above steps are repeated to obtain multiple rotor silicon steel sheets and stator silicon steel sheets, and adjacent stator silicon steel sheets are fixedly connected by glue.

[0070] As the upper die moves toward the lower die 1, the rotor compaction structure 22 applies downward pressure to the silicon steel sheets located in the rotor stacking station 12, and the stator compaction structure 25 applies downward pressure to the silicon steel sheets located in the stator stacking station 15. This causes two adjacent silicon steel sheets to be in close contact, eliminating the gap between the two adjacent silicon steel sheets and avoiding the phenomenon of silicon steel sheet offset. This avoids the phenomenon of uneven thickness of the stator and rotor, thereby improving the production quality of the stator and rotor.

[0071] Furthermore, the adhesive used to fix two adjacent silicon steel sheets is usually an anaerobic adhesive. When the stator compaction structure 25 compacts the silicon steel sheets of the stator, it can expel the air between the two adjacent silicon steel sheets, so that the adhesive can solidify quickly between them, which greatly improves the efficiency of fixing the two adjacent silicon steel sheets together, thereby ensuring the fixing effect of the two adjacent silicon steel sheets.

[0072] It should be noted that the adhesive plate 242 is in the avoidance position only when the robot arm is clamping and moving the silicon steel sheet located at the lowest layer. When the robot arm is clamping the silicon steel sheet located at a non-bottom layer, the adhesive plate 242 is in the adhesive application position so that the silicon steel sheet can be coated with adhesive so that two adjacent silicon steel sheets can be fixedly connected together by adhesive.

[0073] This application does not specify the number of rotor stamping stations 11 and 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 multiple rotor stamping stations 11, and multiple stator stamping dies 23 are provided corresponding to multiple stator stamping stations 13. This allows the silicon steel sheets for the rotor and stator to be formed through multiple stamping processes, reducing stress concentration in the material strip and ensuring the flatness of the surfaces of the silicon steel sheets used for the rotor and stator. Of course, in other embodiments, only one rotor stamping station 11 and one stator stamping station 13 may be provided.

[0074] In a preferred embodiment, refer to Figure 3 , Figure 4 and Figure 5 The connecting seat 241 includes a base plate 244, an upper cover 245, and a connecting post 246 for connecting the base plate 244 and the upper cover 245. The base plate 244 is provided with a guide sleeve 247, and the adhesive plate 242 is provided with a guide post 260 passing through the guide sleeve 247.

[0075] Specifically, the base plate 244 and the top cover 245 are arranged parallel to each other at intervals. The guide sleeve 247 is fixedly connected to the base plate 244, and the guide post 260 is fixedly connected to the top cover 245. Multiple connecting posts 246 are arranged at intervals along the circumference of the base plate 244. One end of each connecting post 246 is fixedly connected to the top cover 245, and the other end of each connecting post 246 is fixedly connected to the base plate 244 to increase the connection stability between the base plate 244 and the top cover 245. Multiple guide sleeves 247 are arranged at intervals along the circumference of the base plate 244, and the guide posts 260 are arranged in a one-to-one correspondence with the guide sleeves 247 to increase the number of guiding points for the adhesive plate 242.

[0076] Since the connecting seat 241 includes a base plate 244, a top cover 245, and a connecting post 246 for connecting the base plate 244 and the top cover 245, the assembly difficulty of the adhesive coating plate 242 can be reduced, thereby improving the assembly efficiency of the dispensing module 24. Furthermore, the base plate 244 is provided with a guide sleeve 247, and the adhesive coating plate 242 is provided with a guide post 260 passing through the guide sleeve 247. As the adhesive coating plate 242 moves, it drives the guide post 260 to move, so that the guide post 260 and the guide sleeve 247 slide relative to each other. This sliding cooperation between the guide post 260 and the guide sleeve 247 guides the movement of the adhesive coating plate 242, thereby increasing the stability of the adhesive coating plate 242 during movement.

[0077] Furthermore, refer to Figure 3 , Figure 4 and Figure 5 An elastic element 261 is provided on the outside of the guide post 260. One bottom end of the elastic element 261 abuts against the guide sleeve 247, and one top end of the elastic element 261 abuts against the adhesive plate 242 to apply an upward elastic force to the adhesive plate 242.

[0078] Since the bottom end of the elastic element 261 abuts against the guide sleeve 247 and the top end of the elastic element 261 abuts against the adhesive coating plate 242, the elastic element 261 can apply an upward elastic force to the adhesive coating plate 242, so that when the adhesive coating plate 242 is in the adhesive coating position, the elastic element 261 can support the adhesive coating plate 242, thereby increasing the number of support points for the adhesive coating plate 242 and increasing the stability of the adhesive coating plate 242 when it is in the adhesive coating position. At the same time, the guide post 260 can also guide the deformation direction of the elastic element 261 to increase the stability of the elastic element 261.

[0079] This application does not specifically limit the structure of the elastic element 261; preferably, refer to... Figure 3 , Figure 4 and Figure 5The elastic element 261 is a spring sleeved on the outside of the guide post 260 to increase the elastic support effect of the elastic element 261 on the adhesive plate 242. In other embodiments, the elastic element 261 can also be a hollow columnar structure made of an elastic material, such as rubber.

[0080] In a preferred embodiment, refer to Figure 3 , Figure 4 and Figure 5 The dispensing module 24 also includes a drive member 243 disposed on the base plate 244. The telescopic end of the drive member 243 is connected to the dispensing plate 242 to move the dispensing plate 242 between the dispensing position and the avoidance position.

[0081] Since the telescopic end of the drive component 243 is connected to the coating plate 242, the drive component 243 can drive the coating plate 242, thereby enabling the coating plate 242 to move automatically between the coating position and the avoidance position, so as to improve the response efficiency of the coating plate 242 when moving between the coating position and the avoidance position, and thus improve the production efficiency of the stator and rotor.

[0082] This application does not specifically limit the structure of the driving component 243. Preferably, the driving component 243 is a cylinder, with the cylinder body fixedly connected to the base plate 244, and the piston rod of the cylinder forming the telescopic end, which is fixedly connected to the bottom of the coating plate 242. In other embodiments, the driving component 243 can also be a hydraulic cylinder, an electric actuator, or other structures capable of driving the coating plate 242 to move axially in the central hole.

[0083] In a preferred embodiment, refer to Figure 5 The upper cover 245 has a stop wall 248. When the glue-applying plate 242 is in the glue-applying position, the glue-applying plate 242 and the stop wall 248 stop and cooperate in the upward direction.

[0084] When the adhesive coating plate 242 is in the adhesive coating position, the adhesive coating plate 242 and the stop wall 248 stop and cooperate in the upward direction, thereby increasing the stability of the adhesive coating plate 242 in the adhesive coating position, so as to ensure the adhesive dispensing effect on the silicon steel sheet.

[0085] This application does not specifically limit the formation method of the stop wall 248; preferably, refer to Figure 5The central hole is a stepped hole. The larger diameter end of the stepped hole is located at the end of the upper cover 245 near the bottom plate 244, and the smaller diameter end is located at the end of the upper cover 245 away from the bottom plate 244. This creates a stop wall 248 at the diameter change of the stepped hole. The adhesive plate 242 is stepped to fit the stepped hole, ensuring that when the adhesive plate 242 is in the adhesive application position, its top surface is flush with the top surface of the upper cover 245, and the adhesive plate 242 engages with the stop wall 248. In other embodiments, the central hole is a variable diameter hole, with its diameter gradually decreasing in the direction away from the bottom plate 244. The outer contour of the adhesive plate 242 matches the shape of the central hole, so that the hole wall forms a stop wall 248.

[0086] In a preferred embodiment, refer to Figure 6 and Figure 7 Both the rotor compaction structure 22 and the stator compaction structure 25 include an elastic column 251 and a compaction member 252. The elastic column 251 has a connecting end connected to the upper mold and a pressure end opposite to the connecting end. The compaction member 252 is located at the pressure end.

[0087] When the upper die moves downward, it drives the elastic column 251 downward, which in turn drives the compaction member 252 downward, so that the compaction member 252 comes into contact with the silicon steel sheet and applies downward pressure to the silicon steel sheet, thereby overcoming the offset of the silicon steel sheet and making two adjacent silicon steel sheets fit tightly to avoid uneven thickness of the stator and rotor. At the same time, due to the setting of the elastic column 251, the compaction member 252 can apply elastic pressure to the silicon steel sheet, so that the compaction member 252 can self-adjust to avoid the phenomenon that the silicon steel sheet is deformed due to excessive pressure applied by the compaction member 252, thus ensuring the production quality of the stator and rotor.

[0088] This application does not specifically limit the structure of the elastic column 251. Preferably, the elastic column 251 includes a first rod 253 having a receiving cavity, a second rod 254 passing through the receiving cavity, and an elastic part 255 provided in the receiving cavity and acting on the second rod 254. The compaction member 252 is provided at the end of the second rod 254 away from the first rod 253.

[0089] When the upper die moves toward the direction closer to the lower die 1, the upper die drives the first rod 253 to move, which in turn drives the second rod 254 to move toward the direction closer to the lower die 1, so that the compaction member 252 abuts against the silicon steel sheet. Then the upper die continues to move toward the direction closer to the lower die 1. At this time, the second rod 254 remains relatively stationary under the action of the silicon steel sheet. The second rod 254 applies pressure to the elastic part 255 in a direction away from the lower die 1. The elastic part 255 deforms and applies a reverse force to the second rod 254, so that the pressure applied by the compaction member 252 to the silicon steel sheet is kept 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.

[0090] This application does not specifically limit the structure of the elastic part 255. Preferably, the elastic part 255 is a spring provided in the accommodating cavity to ensure the elastic support effect on the second rod 254, thereby improving the pressure effect on the silicon steel sheet.

[0091] Furthermore, refer to Figure 6 and Figure 7 The first rod 253 has a limiting groove 257 on its side, and the elastic column 251 also includes a limiting rod 256 that passes through the second rod 254 and the limiting groove 257. The limiting groove 257 is arc-shaped.

[0092] Since the limiting rod 256 passes through the second rod 254 and the limiting groove 257, the cooperation between the limiting rod 256 and the limiting groove 257 can limit the second rod 254 to prevent the second rod 254 from separating from the first rod 253, thereby increasing the connection stability between the second rod 254 and the first rod 253. Furthermore, since the limiting groove 257 is arc-shaped, when the second rod 254 and the first rod 253 slide relative to each other, the second rod 254 can rotate around its own axis under the cooperation of the limiting rod 256 and the limiting groove 257, so that the compaction member 252 can apply rotational force to the silicon steel sheet to overcome the thickness difference caused by the stamping of the silicon steel sheet for the rotor and the silicon steel sheet for the stator, thereby making the thickness of the stator and rotor more uniform and further improving the production quality of the stator and rotor.

[0093] In other embodiments, the elastic column 251 may also be a columnar structure made of an elastic material, such as rubber, etc.

[0094] In a preferred embodiment, refer to Figures 8 to 12Both the rotor stacking station 12 and the stator stacking station 15 are equipped with stacking molds 3. The stacking mold 3 includes a stacking base 31, a follower component 32, and a drive assembly 33. The stacking base 31 has a accommodating space that passes through itself in its own axial direction, and the stacking base 31 passes through the lower mold 1. The follower component 32 is connected to the lower mold 1, and one end of the follower component 32 extends into the accommodating space. The drive assembly 33 is used to drive the stacking base 31 to rotate, and when the stacking base 31 rotates relative to the lower mold 1, the follower component 32 moves toward the outside of the stacking base 31.

[0095] After the robotic arm places the silicon steel sheets into the accommodating space, the follower component 32 blocks the silicon steel sheet located at the bottom layer, so that the silicon steel sheet remains stably in the accommodating space, allowing multiple silicon steel sheets to be stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or after one silicon steel sheet is placed in the accommodating space, the drive component 33 drives the stacking seat 31, which in turn rotates the stacking seat 31 relative to the lower mold 1 by 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 two adjacent silicon steel sheets are completely attached. This avoids the influence of uneven workpiece thickness caused by the stamping of silicon steel sheets on the overall thickness of the stator and rotor, thereby ensuring the uniformity of the stator and rotor thickness and thus ensuring the production quality of the stator and rotor.

[0096] In addition, when the stacking base 31 rotates relative to the lower mold 1, the follower member 32 moves toward the outside of the stacking base 31 under the action of the lower mold 1 and the stacking base 31. 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 can avoid each other. This allows the stacked silicon steel sheets to fall through the bottom opening of the accommodating space, thereby releasing the stacked silicon steel sheets so that the workers can carry out the next step of processing. This greatly improves the production efficiency of the stator and rotor.

[0097] In a preferred embodiment, refer to Figures 8 to 12 The follower component 32 has a connecting section 321 and a stop section 322. The stop section 322 passes through the stacking base 31. The lower mold 1 has an arc-shaped groove 163 extending circumferentially along the stacking base 31. The distance between the arc-shaped groove 163 and the accommodating space gradually increases along the circumferential direction of the stacking base 31. The connecting section 321 passes through the arc-shaped groove 163.

[0098] As the distance between the arc-shaped groove 163 and the accommodating space gradually increases along the circumference of the stacking base 31, and the connecting section 321 passes through the arc-shaped groove 163, when the stacking base 31 and the lower mold 1 rotate relative to each other, the follower member 32 can rotate with the stacking base 31 under the action of the stop section 322. This causes the connecting section 321 of the follower member 32 to slide relative to the arc-shaped groove 163, so that the follower member 32 moves towards the outside of the stacking base 31 under the relative rotation of the stacking base 31 and the lower mold 1. As the number of silicon steel sheets stacked together increases, the stop section 322 and the stop area of ​​the silicon steel sheets decreases. Finally, after the required number of silicon steel sheets are stacked, the stop section 322 releases its stop from the silicon steel sheets, 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 163 can also limit the movement of 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.

[0099] Preferably, the stop section 322 is arranged perpendicularly to the connecting section 321, thereby making the follower member 32 L-shaped to increase the stopping effect on the silicon steel sheet.

[0100] If the distance between the arc-shaped groove 163 and the inner wall of the accommodating space gradually increases in the clockwise direction, then when the stacking seat 31 rotates clockwise under the action of the driving component 33, the follower component 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-shaped groove 163 and the inner wall of the accommodating space gradually increases in the counterclockwise direction, then when the stacking seat 31 rotates counterclockwise under the action of the driving component 33, the follower component 32 moves toward the outside of the stacking seat 31 under the action of the stacking seat 31 and the lower mold 1.

[0101] Furthermore, the arc-shaped groove 163 passes through the lower mold 1 in the axial direction, the stacking seat 31 is provided with a passage 312, the stop section 322 passes through the passage 312, and the stacking seat 31 is provided with a reset member 311 acting on the stop section 322. The reset member 311 can apply an upward elastic force to the stop section 322.

[0102] Because the arc-shaped groove 163 passes through the lower mold 1 in the axial direction, and the stacking seat 31 is provided with a passage 312, the stop section 322 passes through the passage 312, and the stacking seat 31 is provided with a reset member 311 acting on the stop section 322, the stop section 322 can elastically move in the axial direction of the stacking seat 31 according to the change in the number of silicon steel sheets. On the one hand, it reduces the distance that the silicon steel sheets need to move when they are placed in the accommodating space, so as to reduce the phenomenon that the silicon steel sheets may come into contact with the inner wall of the accommodating space and become biased, thereby further ensuring the uniformity of the stator and rotor thickness. On the other hand, it realizes that as the number of silicon steel sheets placed above the stop section 322 gradually increases, the stop section 322 moves downward elastically 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.

[0103] This application does not specifically limit the structure of the reset member 311, which can adopt any of the following embodiments:

[0104] Example 1, in this example, refers to Figure 9 The reset member 311 is a spring sleeved on the outside of the stacking base 31. The stacking base 31 has a support portion 313, which is located at the bottom of the spring to support the spring.

[0105] Since the support portion 313 is located at the bottom of the spring, it can support the spring, thereby increasing the elastic support effect of the spring on the stop section 322. Furthermore, the spring is sleeved on the outside of the stacking base 31, allowing it to avoid interfering with the falling of the silicon steel sheets within the space, thus ensuring efficient stacking of the silicon steel sheets. Additionally, because the spring is sleeved on the outside of the stacking base 31, the stacking base 31 can also guide the deformation of the spring, increasing its stability during deformation.

[0106] This application does not specifically limit the structure of the support portion 313. Preferably, the support portion 313 is a ring structure extending circumferentially along the stacking base 31 to increase the number of support points for the spring, thereby increasing the stability of the spring. In other embodiments, the support portion 313 may also be a block structure spaced circumferentially along the stacking base 31.

[0107] Example 2, in this example, refer to Figure 11 and Figure 12 The reset member 311 is a spring provided in the passage 312, with one bottom end of the spring contacting the wall of the passage 312 and one top end of the spring contacting the bottom of the stop section 322.

[0108] Since the reset member 311 is a spring located in the passage 312, the reset member 311 can avoid the phenomenon that the spring is located outside the stacking seat 31 and thus imposes a high requirement on the gap between the stacking seat 31 and the lower mold 11, thereby reducing the assembly difficulty of the stacking seat 31 and improving the assembly efficiency of the stator and rotor production and processing device.

[0109] In this embodiment, the method of installing the spring is not specifically limited, and it can be any of the following implementation examples:

[0110] Implementation Example 1, in this implementation example, refer to Figure 11 A positioning post 315 is provided through the wall of the opening 312, and a spring is sleeved on the positioning post 315.

[0111] Specifically, the positioning post 315 is located on the bottom wall of the through-hole 312, and one bottom end of the spring is sleeved on the outside of the positioning post 315, and the inner circumferential surface of the bottom end of the spring is interference-fitted with the positioning post 315.

[0112] Since the spring is sleeved on the positioning post 315, the positioning post 315 can position the spring to avoid the spring from separating from the positioning post 315. This increases the connection stability between the spring and the through port 312 and reduces the difficulty of installing the spring, thereby further improving the assembly efficiency of the stacked mold 3.

[0113] Implementation Example 2, in this implementation example, refer to Figure 12 The top of the spring is provided with a low-resistance plate 316 located at the bottom of the stop section 322. The low-resistance plate 316 is provided with a guide rod 317 passing through the spring. The stacking seat 31 is provided with a guide hole 314 for accommodating the guide rod 317.

[0114] Because the top of the spring is provided with a low-resistance plate 316 located at the bottom of the stop section 322, on the one hand, the spring contacts the stop section 322 through the low-resistance plate 316 to reduce the friction between the spring and the stop section 322, so as to ensure the smooth movement of the follower component 32 toward the outside of the stacking seat 31. On the other hand, it makes the force on the top end of the spring more balanced, so as to prevent the spring from detaching from the side of the passage 312, thereby increasing the stability of the spring. Furthermore, the low-resistance plate 316 is provided with a guide post 260, and the stacking seat 31 is provided with a guide hole 314 for accommodating the guide rod 317. When the spring moves downward under the pressure of the stop section 322, the guide rod 317 slides relative to the guide hole 314. On the one hand, the guide rod 317 can guide the deformation direction of the spring to increase the stability of the spring when it deforms, thereby ensuring the elastic support effect of the stop section 322. On the other hand, it can also increase the connection stability between the spring and the stacking seat 31.

[0115] This application does not specify the connection method between the guide rod 317 and the low-resistance plate 316. Preferably, the guide rod 317 and the low-resistance plate 316 are fixedly connected to increase the connection stability between the guide rod 317 and the low-resistance plate 316. In other embodiments, the guide rod 317 can also be threadedly connected to the low-resistance plate 316.

[0116] In other embodiments, the reset member 311 may also be an elastic sheet or other elastic structure.

[0117] In a preferred embodiment, the lower mold 1 has a mounting base 16, and a stacking base 31 is disposed through the mounting base 16. The mounting base 16 includes a body 161 and an annular body 162 disposed inside the bottom end of the body 161. An arcuate groove 163 is disposed in the annular body 162. The stacking base 31 has an edge 318 that can cooperate with the top stop of the body 161.

[0118] Since the lower mold 1 has a mounting base 16 and the stacking base 31 passes through the mounting base 16, the installation difficulty of the stacking base 31 can be reduced, thereby improving the assembly efficiency of the stator and rotor production and processing device. Furthermore, since the arc-shaped groove 163 is provided in the ring body 162, the stacking base 31 can be completely hidden in the lower mold 1. By reducing the size of the lower mold 1, it is easier to miniaturize the stator and rotor production and processing device. The stacking base 31 has an edge 318 that can cooperate with the top stop of the body 161, so that the cooperation between the edge 318 and the mounting base 16 can support the stacking base 31, thereby increasing the stability of the stacking base 31. In addition, since the arc-shaped groove 163 is provided in the ring body 162, the follower member 32 can slide within a relatively large range, thereby further shortening the distance that the silicon steel sheet to be placed in the accommodating space needs to move, thereby further ensuring the production quality of the stator and rotor.

[0119] This application does not specifically limit the structure of the drive assembly 33. Preferably, the drive assembly 33 includes an external gear ring 331 disposed at the bottom of the stacking base 31, a drive gear 332 meshing and transmitting with the external gear ring 331, and a power component for driving the drive gear 332 to rotate.

[0120] When the stacking seat 31 is driven, the power unit is activated, which drives the drive gear 332, which in turn drives the external gear ring 331 to rotate. The external gear ring 331 drives the stacking seat 31 to rotate, thereby driving the stacking seat 31 to rotate.

[0121] This application does not specify a particular structure for the power component. Preferably, the power component is a servo motor to achieve precise control over the rotation angle of the stacking seat 31. In other embodiments, the power component can also be a pneumatic motor or other structures capable of driving the drive gear 332 to rotate.

[0122] Furthermore, refer to Figure 8 and Figure 9 The drive assembly 33 also includes a fixed base 333, and the drive gear 332 is located inside the fixed base 333. The drive gear 332 has a transmission shaft passing through the fixed base 333, which increases the stability of the drive gear 332, reduces the assembly difficulty of the drive gear 332, and ensures the transmission efficiency between the drive gear 332 and the external gear ring 331.

[0123] This application does not impose specific limitations on the transmission connection method between the servo motor and the drive gear 332. Preferably, the output shaft of the servo motor is provided with a gear that meshes and transmits power with the drive gear 332, thereby realizing the transmission connection between the servo motor and the drive gear 332 and reducing the height of the drive assembly 33. In other embodiments, the output shaft of the servo motor and the rotating shaft are connected by a coupling.

[0124] In other embodiments, the drive assembly 33 includes a hollow rotating platform and a drive member 243. The output end of the hollow rotating platform is coaxially and fixedly connected to the stacking base 31, and the drive member 243 is drively connected to the input end of the hollow rotating platform.

[0125] Reference Figure 13 This application also discloses a method of using a stator and rotor production and processing device, which is used in the above-mentioned stator and rotor production and processing device, including the following steps: S1, feeding material, extending one end of the material strip between the upper mold and the lower mold 1, while making the beginning end of the material strip completely cover the top of the rotor stamping station 11.

[0126] S2, Stamping: The upper die moves toward the direction closer to the lower die 1 so that the rotor stamping die head 21 stamps the strip. The part of the strip opposite to the rotor stamping station 11 forms a silicon steel sheet for the rotor. Then the upper die moves away from the lower die 1 so that the upper die is reset.

[0127] S3, Stacking: The robot arm places the formed rotor with silicon steel sheets into the rotor stacking station 12, and then the robot arm resets to avoid the upper mold.

[0128] S4. Push the material, continue to push the strip between the upper die and the lower die 1 so that the unpressed part of the strip moves to the rotor stamping station 11, and at the same time the part of the strip with the silicon steel sheet for the rotor punched off moves to the stator stamping station 13.

[0129] S5. Stamping is performed again. The upper die moves toward the direction closer to the lower die 1. The rotor stamping die 21 stamps the strip, and the stator stamping die 23 stamps the strip. The part of the strip opposite to the rotor stamping station 11 forms a new rotor silicon steel sheet, and the part of the strip opposite to the stator stamping station 13 forms a stator silicon steel sheet. Then the upper die moves toward the direction away from the lower die 1 so that the upper die is reset.

[0130] S6. Stacking and dispensing: The robot places the formed rotor silicon steel sheet at the rotor stacking station 12, the robot places the formed stator silicon steel sheet at the dispensing station 14, and then the robot places the stator silicon steel sheet that has passed through the dispensing station 14 at the stator stacking station 15.

[0131] It should be noted that when the robotic arm clamps and moves the first stator silicon steel sheet, that is, when the robotic arm clamps and moves the silicon steel sheet located at the bottom layer, the adhesive plate 242 is in a clearance position so that the adhesive flowing out through the adhesive outlet 249 avoids the silicon steel sheet, thus preventing the first silicon steel sheet from being coated with adhesive. However, when the robotic arm clamps and moves silicon steel sheets that are not located at the bottom layer, the adhesive plate 242 is in the adhesive application position so that adhesive can be applied to the bottom of the silicon steel sheet.

[0132] During the S7 and S4-S6 cycles, as the upper mold moves toward the lower mold 1, the rotor compaction structure 22 applies downward pressure to the silicon steel sheet located at the rotor stacking station 12, and the stator compaction structure 25 applies downward pressure to the silicon steel sheet located at the stator stacking station 15. This causes adjacent silicon steel sheets to adhere tightly, ensuring the uniformity of the stator and rotor thickness. At the same time, it also allows the air between the two connected stator silicon steel sheets to be quickly discharged, accelerating the solidification of the colloid.

[0133] By using the above-described method to produce stators and rotors, the steps required for stator and rotor production are simplified, thereby improving the production efficiency of stators and rotors.

[0134] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0136] The above description is merely an embodiment of this application and is not intended to limit this application.
