Description

Technical Field

[0001] The present invention relates to a welding device, and particularly to a stator stacking and welding device for a new energy vehicle motor. Background Art

[0002] The stator is one of the core components of a new energy vehicle motor, which is formed by stacking multiple stator steel sheets and fixing them by welding. In order to ensure the overall strength and electromagnetic performance of the stator, it is necessary to accurately stack multiple stator steel sheets and perform firm welding. During the welding process, it is required that the steel sheets of each layer are closely attached to prevent poor welding or thermal deformation caused by the interlayer gap from affecting the overall structural stability.

[0003] Currently, during the welding process of stator steel sheets, it is usually dependent on manual operation to stack the steel sheets layer by layer. After the stacking is completed, the stacked steel sheets are transferred under a pressing device, and a simple pressing device is used to press the steel sheets, and then the welding operation process is carried out. This operation process not only has cumbersome procedures, excessive manual intervention, and high labor intensity of workers, but also is prone to problems such as low stacking accuracy of steel sheets and loose interlayer adhesion during manual operation. Summary of the Invention

Detailed implementation manners

[0027] The embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0028] A stator laminating and welding device for new - energy vehicle motors, as Figures 1-10As shown in the figure, it includes an electric rotating table 1, a connecting frame 102, a material rack 103, a rotating cover 1031, a torsion spring A 1032, a transmission device 602, a feeding mechanism 2, a pressing plate 202, a support member 405 and a welding torch 4043. A plurality of connecting frames 102 are circumferentially and spacedly arranged on the electric rotating table 1. A material rack 103 is rotatably connected within each connecting frame 102. The material rack 103 is used to place and stack stator steel sheets 9. The material rack 103 is divided into upper and lower parts, and the connection relationship between the upper and lower parts is a rotational connection. The middle part of the material rack 103 is sleeved with a rotating cover 1031 (i.e., the rotating cover 1031 is connected to the upper part of the material rack 103). A torsion spring A 1032 is connected inside the rotating cover 1031, and the other end of the torsion spring A 1032 is connected to the material rack 103 (i.e., the other end of the torsion spring A 1032 is connected to the lower part of the material rack 103). When the rotating cover 1031 is rotated, the upper part of the material rack 103 will rotate accordingly, and the torsion spring A 1032 changes from its initial state to a compressed state. A transmission device 602 is installed on the right side of the electric rotating table 1. The transmission device 602 can transmit the stator steel sheets 9. A feeding mechanism 2 is installed on the transmission device 602. The feeding mechanism 2 can transfer the stator steel sheets 9 from the transmission device 602 to the material rack 103. The lower part of the front end of the feeding mechanism 2 is connected with a pressing plate 202, and the pressing plate 202 can contact the rotating cover 1031. A pre-pressing mechanism 3 is connected to the rear side of the electric rotating table 1. The pre-pressing mechanism 3 can pre-press the stacked stator steel sheets 9 to ensure the tight fit between each layer of stator steel sheets 9, which is beneficial to improving the welding quality. The pre-pressing mechanism 3 includes a support frame 301, a sliding frame 302, a blocking block 3021, a pressing block 3022 and a long spring 303. A support frame 301 is connected to the rear side of the electric rotating table 1. A V-shaped groove 3023 is opened in the upper part of the support frame 301. The front middle part of the support frame 301 is slidably connected with a sliding frame 302. The lower part of the front end of the sliding frame 302 is provided with a blocking block 3021, and the blocking block 3021 can slide along the V-shaped groove 3023. A pressing block 3022 is slidably connected to the sliding frame 302. A long spring 303 is connected between the sliding frame 302 and the support frame 301. Multiple welding torches 4043 are arranged on the support member 405.

[0029] As Figure 1 and 4 shown in the figure, the feeding mechanism 2 includes an electric guide rail 201, a moving frame 203, a linear guide rail A 204 and an electric suction cup 205. An electric guide rail 201 is installed on the left side of the rear end of the transmission device 602. A moving frame 203 is connected to the moving part of the electric guide rail 201. Linear guide rails A 204 are symmetrically arranged on the upper part of the front end of the moving frame 203 on the left and right. A lifting frame 2041 is connected between the moving parts of the two linear guide rails A 204. An electric suction cup 205 is connected to the bottom end of the lifting frame 2041. The electric suction cup 205 is used to adsorb and transfer the stator steel sheets 9.

[0030] As Figure 1 , Figure 7 and Figure 8 shown, the support member 405 includes a support base 401, a connection shell 402, a linear guide rail B404 and a connection ring 4041. The left end of the electric rotary table 1 is connected to the support base 401. The top of the support base 401 is connected to the connection shell 402. Two linear guide rails B404 are installed at the top of the support base 401. A connection ring 4041 is connected between the moving members of the two linear guide rails B404. The welding torches 4043 are circumferentially arranged at intervals inside the connection ring 4041. The two linear guide rails B404 drive the connection ring 4041 and the welding torches 4043 thereon to move downward to weld the stacked stator steel sheets 9.

[0031] As Figure 7 and Figure 8 shown, it further includes a guide rod 403, a pressing block 4031, a short spring 4032, a contact block 4033 and an arc-shaped contact plate 4042. A guide rod 403 is provided in the middle of the connection shell 402. A circular pressing block 4031 is slidably connected to the lower part of the guide rod 403. A short spring 4032 is connected between the pressing block 4031 and the guide rod 403. The short spring 4032 is in a compressed state and is sleeved on the guide rod 403. Contact blocks 4033 are symmetrically arranged on the front and rear sides of the top of the pressing block 4031. Arc-shaped contact plates 4042 are symmetrically arranged on the front and rear sides inside the connection ring 4041. The arc-shaped contact plates 4042 abut against the pressing block 4031. When the linear guide rail B404 drives the arc-shaped contact plate 4042 to move downward, the arc-shaped contact plate 4042 will no longer abut against the pressing block 4031. Under the action of the short spring 4032, the pressing block 4031 will press down on the stacked stator steel sheets 9, so that the stacked stator steel sheets 9 are kept in close contact with each other, avoiding layer separation caused by thermal deformation during the welding process and ensuring stable welding quality.

[0032] As Figure 1 , Figure 9 and Figure 10As shown in the figure, it further includes a blocking platform 5 and a torsion spring B1033. Slide holes 1021 are formed in the connecting frame 102. The lower part of the rack 103 can rotate along the slide holes 1021. The lower part of the front side of the electric rotating platform 1 is connected with the blocking platform 5. An inclined surface 501 is provided at the left end of the blocking platform 5. Two torsion springs B1033 are sleeved on the lower part of the rack 103. The other ends of the two torsion springs B1033 are connected with the connecting frame 102. After the stator steel sheets 9 are welded, during the process that the rack 103 rotates to the front end of the electric rotating platform 1, the lower part of the rack 103 will first contact the inclined surface 501 on the blocking platform 5. During this process, the lower part of the rack 103 will rotate backward and upward along the slide holes 1021, the upper part of the rack 103 will tilt downward at the front side, and the two torsion springs B1033 will change from the initial state to the compressed state. Finally, the rack 103 changes from the vertical state to the horizontal state. At this time, the stator steel sheets 9 on the rack 103 can be removed. During the process that the electric rotating platform 1 rotates 90 degrees again, the rack 103 located on the blocking platform 5 will no longer contact the blocking platform 5. At this time, the two torsion springs B1033 will reset. Under the action of the two torsion springs B1033, the rack 103 changes from the horizontal state to the vertical state.

[0033] As Figure 1 shown in the figure, the transmission device 602 includes a base 6, a transmission belt 601 and a door panel 603. The base 6 is installed on the right side of the electric rotating platform 1. The transmission belt 601 is provided at the top of the base 6. The electric suction cup 205 is located below the transmission belt 601. Cavities are symmetrically arranged inside the base 6 from left to right. Door panels 603 are hinged at the front ends of the cavities. The cavities arranged inside the base 6 can be used to place maintenance equipment. Rotate and open the door panels 603, and the maintenance equipment can be placed inside the base 6.

[0034] As Figure 1 shown in the figure, it further includes a circular ring block 1034. The circular ring block 1034 is sleeved on the upper part of the rack 103. Grooves are circumferentially spaced on the circular ring block 1034. The annularly distributed protrusions in the stator steel sheet 9 can be inserted into the grooves on the circular ring block 1034, and the two are mutually adapted.

[0035] In this embodiment, taking Figure 1For reference, each rotation of the electric rotating table 1 is counterclockwise and the rotation angle is 90 degrees. When the device is working, the stator steel sheet 9 is transported to directly below the electric suction cup 205 through the conveyor belt 601. The linear guide rail A204 transfers the stator steel sheet 9 to the storage rack 103. The working conditions of each component are as follows: start the linear guide rail A204, and the linear guide rail A204 drives the lifting frame 2041 to move downward. Start the electric suction cup 205. When the electric suction cup 205 contacts the stator steel sheet 9, the electric suction cup 205 sucks the stator steel sheet 9. The linear guide rail A204 drives the lifting frame 2041 and the stator steel sheet 9 thereon to move upward a certain distance, so that the horizontal height of the stator steel sheet 9 is slightly higher than the top of the storage rack 103. Then the electric guide rail 201 is started, and the electric guide rail 201 drives the moving frame 203 and the stator steel sheet 9 thereon to come directly above the storage rack 103. During the leftward movement of the electric guide rail 201, the pressing plate 202 will move along with the electric guide rail 201. The pressing plate 202 will press the rotating cover 1031, causing the rotating cover 1031 to rotate to the left. See Figure 4, the upper part of the material rack 103 will rotate together with the rotating cover 1031, and the lower part of the material rack 103 remains stationary. During the rotation of the rotating cover 1031, the torsion spring A1032 will change from the initial state to the compressed state, the electric suction cup 205 will be closed, and the stator steel sheet 9 on the electric suction cup 205 will fall onto the upper part of the material rack 103 and the top of the circular ring block 1034. Since there are annularly distributed protrusions on the inner ring of the stator steel sheet 9 and slots are circumferentially spaced on the circular ring block 1034, it is difficult for the stator steel sheet 9 to be directly sleeved onto the circular ring block 1034. After that, the electric guide rail 201 drives the sliding frame 302 and the components thereon back to the initial position. At this time, the pressing plate 202 no longer presses against the rotating cover 1031. Under the action of the torsion spring A1032, the rotating cover 1031 and the upper part of the material rack 103 will rotate to the right and return to the initial position, and then rotate to the left. The upper part of the material rack 103 rotates and sways left and right. During this process, the stator steel sheet 9 located at the top of the circular ring block 1034 will fall from the top of the circular ring block 1034 and be sleeved onto the outside of the circular ring block 1034. The electric guide rail 201 repeats the transfer of the stator steel sheet 9 onto the material rack 103, and each component will repeat the above movement process. When the stator steel sheets 9 on the material rack 103 reach the predetermined quantity, the electric rotating table 1 will drive the stacked stator steel sheets 9 on the material rack 103 to rotate to the back side and perform pre-pressing. During the process that the electric rotating table 1 drives the right-side material rack 103 and the stator steel sheets 9 thereon to rotate 90 degrees, the rotating cover 1031 on the material rack 103 will contact the blocking block 3021, and the rotating cover 1031 will push the blocking block 3021 to move. The long spring 303 connected to the sliding frame 302 will be gradually compressed, and the long spring 303 changes from the initial state to the compressed state. Initially, since the elastic potential energy accumulated in the long spring 303 is not enough to push the rotating cover 1031 to rotate, the blocking block 3021 will move together with the rotating cover 1031. During the process that the blocking block 3021 moves to the left, under the action of the V-shaped groove 3023, the pressing block 3022 will gradually fall from the right top of the V-shaped groove 3023 to the middle bottom end of the V-shaped groove 3023. When the rear side of the pressing block 3022 reaches the middle bottom end of the V-shaped groove 3023, the pressing block 3022 just presses tightly on the top of the stator steel sheet 9. After that, the pressing block 3022 presses on the top of the material rack 103 and rotates to the back side of the electric rotating table 1 following the material rack 103. The other material racks 103 rotate 90 degrees in turn. The front-side material rack 103 rotates to the right side, and the electric guide rail 201 transfers the stator steel sheet 9 on the conveyor belt 601 to this material rack 103. After the stator steel sheets 9 on this material rack 103 are loaded, the electric rotating table 1 rotates counterclockwise by 90 degrees again. At this time, the material rack 103 located at the back side of the electric rotating table 1 will continue to rotate 90 degrees, and the rotating cover 1031 continues to push the blocking block 3021 to move to the left. When the rear side of the pressing block 3022 leaves the middle bottom end of the V-shaped groove 3023 and moves to the left top of the V-shaped groove 3023, at this time,The long spring 303 has been compressed by a sufficient length, and the elastic potential energy within the long spring 303 has also accumulated to a sufficient amount. Therefore, the blocking block 3021 will push the rotating cover 1031 to rotate. After the rotating cover 1031 has rotated through a certain angle, the rotating cover 1031 will slide past the front end of the blocking block 3021, realizing the separation of the material rack 103 and the sliding rack 302. After that, the material rack 103 will rotate to the left side of the electric rotating table 1. When the pressing block 3022 moves to the left top of the V-shaped groove 3023 at the rear side of the pressing block 3022, the pressing block 3022 automatically separates from the stator steel sheet 9. After the rotating cover 1031 no longer pushes the blocking block 3021, the long spring 303 changes from the compressed state to the initial state, and the long spring 303 will drive the moving rack 203 back to the initial position, and the pressing block 3022 will also return to the initial position. Then, welding is performed on the stacked stator steel sheets 9 on the material rack 103. The linear guide rail B404 drives the connecting ring 4041 and the welding torch 4043 thereon to move downward together, and the arc contact plate 4042 moves together therewith. At this time, since the short spring 4032 is in the compressed state initially, the short spring 4032 will push the pressing block 4031 downward. Finally, the pressing block 4031 abuts against the top end of the stator steel sheet 9. At this time, the short spring 4032 is still in the compressed state, and the short spring 4032 will squeeze the pressing block 4031 to press it against the top end of the stacked stator steel sheets 9. When the nozzle of the welding torch 4043 touches the welding point on the stator steel sheet 9, the welding torch 4043 is started, and the welding torch 4043 welds the stator steel sheet 9. The linear guide rail B404 drives the welding torch 4043 to weld the stator steel sheet 9 from top to bottom. After the welding is completed, the linear guide rail B404 drives the welding torch 4043 back to the initial position, and the arc contact plate 4042 pushes the contact block 4033 and the pressing block 4031 upward to return to the initial position. After that, the electric rotating table 1 rotates counterclockwise by 90 degrees again, and rotates the welded stator steel sheet 9 to the front end of the electric rotating table 1.,

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
