Description

Technical Field

[0001] The present invention relates to the technical field of brushless DC motor production, and specifically to a stator assembly of a brushless DC motor and a manufacturing method thereof. Background Technique

[0002] A brushless DC motor (BLDC) is a synchronous motor. Its rotor is composed of permanent magnets, and its stator is composed of silicon steel sheets wound with electromagnetic coils. Different from traditional brushed DC motors, a brushless DC motor does not have a mechanical commutator, but uses an electronic commutator to control the current direction to achieve the rotation of the rotor. A brushless DC motor is an efficient, reliable, and low-noise motor and is widely used in various fields. During the production process of the stator assembly of a brushless DC motor, it is necessary to cut, stack, and press the silicon steel sheets to form the stator assembly.

[0003] Common manufacturing methods for stator assemblies on the market usually involve first uniformly cutting the silicon steel sheets, then neatly stacking and arranging them, and finally pressing them into shape. The above three steps are all separate steps, which results in the need for positioning and adjustment during the cutting, stacking, and pressing processes of the silicon steel sheets to ensure the shape and dimensional accuracy of the formed stator assembly. These operations will greatly affect the production efficiency of the stator assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a stator assembly of a brushless DC motor and a manufacturing method thereof to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present invention provides the following technical solutions: A stator assembly of a brushless DC motor and its manufacturing method, including a frame, a stacking assembly, and a shearing assembly. A support assembly is arranged inside the frame, and a stacking assembly is arranged at the outer end of the top of the frame. A second motor is arranged on the outer side of the top of the frame, and a lead screw is arranged at the output end of the second motor. A shearing assembly is arranged at the outer end of the lead screw, and the shearing assembly includes a lifting seat, a lead screw slide seat, a first hydraulic cylinder, a downward pushing seat, a docking head, a positioning block, a positioning pile, a shearing knife, an electric pushing seat, a socketed suction pump, an adsorption seat, and an adsorption groove. Screw slide seats are arranged on both outer sides of the lifting seat, and a first hydraulic cylinder is arranged on the outer side of the bottom of the lifting seat. A downward pushing seat is arranged at the bottom end of the first hydraulic cylinder, and a docking head is arranged on the outer side of the bottom of the downward pushing seat. A positioning block is arranged on the inner edge of the docking head, and a positioning pile is arranged in the middle of the inside of the docking head. A shearing knife is arranged at the outer end of the bottom of the docking head. An electric pushing seat is arranged at the outer end of the docking head, and a socketed suction pump is arranged at the output end of the electric pushing seat. The socketed suction pump is arranged at the bottom end of the adsorption seat, and an adsorption groove is opened at the bottom end of the adsorption seat. A second hydraulic cylinder is arranged at the right end of the top of the frame, and a pressing seat is connected to the output end of the second hydraulic cylinder. Silicon steel sheets are stacked at the outer end of the stacking assembly.

[0006] Further, the support assembly includes a support seat, a driving gear, a support plate, and a tooth groove. Support seats are arranged at both outer ends of the frame, and a driving gear is arranged inside the frame. A support plate passes through the frame and the support seats, and tooth grooves are opened on both outer sides of the support plate.

[0007] Further, the driving gear meshes with the tooth groove, and the support plate is displaced inside the support seat and the driving gear by rotating the driving gear.

[0008] Further, the rotation of the lead screw causes the lead screw slide seat to drive the lifting seat to move up and down, and the operation of the first hydraulic cylinder drives the downward pushing seat to move down.

[0009] Further, the docking head and the shearing knife are integrated, and the docking head is sleeved and connected with the socketed suction pump.

[0010] Further, the stacking assembly includes a first motor, a rotating table, a support frame, a ball, a first stacking seat, a plug connector, a positioning groove, a positioning hole, a second stacking seat, and a positioning head. The output end of the first motor is provided with a rotating table, and a support frame is arranged on the outer side of the top of the rotating table. A ball is arranged on the outer side of the bottom of the support frame. A first stacking seat is arranged at the left end of the top of the support frame, and a plug connector is arranged on the outer side of the top of the first stacking seat. A positioning groove is opened at the outer end of the plug connector, and a positioning hole is opened on the inner side of the plug connector. A second stacking seat is arranged on the right side of the top of the rotating table, and a positioning head is connected to the middle of the inner side of the second stacking seat.

[0011] Furthermore, silicon steel sheets are stacked at the outer end of the first stacking seat and the inner end of the second stacking seat, and the first stacking seat and the second stacking seat are symmetrically distributed along the vertical center line of the rotating table.

[0012] Furthermore, the inner contour size of the butt joint matches the outer contour size of the plug joint, and the size of the positioning pile matches the size of the positioning hole.

[0013] Furthermore, the outer contour size of the sleeve-type suction pump matches the inner contour size of the second stacking seat, and the outer contour size of the press-fit seat matches the inner contour size of the second stacking seat.

[0014] The present invention provides a stator assembly of a brushless DC motor and a manufacturing method thereof, which have the following beneficial effects:

[0015] 1. The present invention drives the lead screw to rotate and drive the slide to move downward by the second motor, so that the docking joint is accurately positioned to the plug-in position. The plug-in accuracy is ensured based on the matching internal and external contours and the positioning slot design. After the docking is completed, the electric push seat drives the sleeve-type suction pump to press down and adsorb the silicon steel sheet, and the second motor reverses and lifts the docking joint to achieve material separation; then the gear is driven to engage the tooth groove to drive the support plate to move under the adsorption seat, and the electric push seat lifts the silicon steel sheet to the shearing position. The first hydraulic cylinder presses down the docking joint to make the material close to the support plate, and finally the shear knife is driven by continuous pressure to complete the precise cutting. This structure significantly improves the preparation efficiency and dimensional accuracy of the stator assembly by collaboratively controlling the timing actions of positioning, adsorption, separation and shearing components.

[0016] 2. After the shearing is completed, the electric push seat drives the sleeve-type suction pump to move upward. At this time, the shearing knife presses the waste slag against the surface of the support plate, and the adsorption seat applies an upward lifting force to the silicon steel sheet to realize the active separation of the waste slag and the material. Then the first hydraulic cylinder retreats to make the shearing knife separate from the support plate, and the driving gear engages in reverse to drive the support plate to move the waste slag out of the frame. The waste slag can be easily cleaned by mechanical claws or manually to ensure the continuous operation of the equipment. This process effectively avoids waste retention through the linkage control of adsorption separation and displacement mechanism, and ensures the stability and reliability of continuous operation of the shearing system.

[0017] 3. The electric push seat of the present invention drives the adsorption seat to carry the silicon steel sheet to the bottom of the shearing knife, and at the same time, the first motor drives the rotating table to rotate, so that the first and second stacking seats symmetrically distributed on the vertical center line complete the station interchange, and the screw drives the lifting seat to move downward, and the adsorption seat accurately guides the silicon steel sheet into the second stacking seat. Based on the positioning logic homologous to the shearing process (the inner contour of the adsorption seat matches the outer size of the stacking seat, and the shape of the positioning head fits the shearing contour), the silicon steel sheet is automatically aligned and stacked in the stacking seat after shearing. This design integrates the shearing positioning and pressing positioning systems to execute the shearing and stacking processes in series, eliminates repeated positioning links, and significantly improves the continuity and preparation efficiency of the silicon steel sheet shearing and stacking process.

[0018] 4. After the silicon steel sheets of the present invention are positioned in the second stacking base, the first motor drives the turntable to reset, so that the second stacking base and the first stacking base return to the initial symmetric working positions. Then the equipment restarts the cycle process of the shearing assembly adsorbing new materials from the first stacking base. At the same time, after the second stacking base is reset, the second hydraulic cylinder immediately drives the pressing base to press down. Based on the design logic of pressing while stacking once, a pressing force is directly applied to the current silicon steel sheets and the stacking group, avoiding the problem of layer looseness caused by uneven pressure conduction in traditional batch pressing, thereby significantly improving the tightness of the stator assembly laminations and the overall pressing quality. This sequential pressing strategy ensures uniform stress on the laminations by applying pressure piece by piece in real time, and synchronously optimizes the production rhythm and process reliability.

Detailed implementation manner

[0027] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a manufacturing device for a motor stator assembly, including a frame 1, a stacking assembly 3 and a shearing assembly 6. A support assembly 2 is arranged inside the frame 1, and a stacking assembly 3 is arranged at the outer end of the top of the frame 1. A second motor 4 is arranged on the outer side of the top of the frame 1, and a lead screw 5 is arranged at the output end of the second motor 4. A shearing assembly 6 is arranged at the outer end of the lead screw 5, and the shearing assembly 6 includes a lifting seat 601, a lead screw slide seat 602, a first hydraulic cylinder 603, a lower pushing seat 604, a docking head 605, a positioning block 606, a positioning pile 607, a shearing knife 608, an electric pushing seat 609, a socket type suction pump 610, an adsorption seat 611 and an adsorption groove 612. Lead screw slide seats 602 are arranged on both outer sides of the lifting seat 601, and a first hydraulic cylinder 603 is arranged on the outer side of the bottom of the lifting seat 601. A lower pushing seat 604 is arranged at the bottom end of the first hydraulic cylinder 603, and a docking head 605 is arranged on the outer side of the bottom of the lower pushing seat 604. A positioning block 606 is arranged on the inner edge of the docking head 605, and a positioning pile 607 is arranged in the middle of the inside of the docking head 605. A shearing knife 608 is arranged at the outer end of the bottom of the docking head 605. An electric pushing seat 609 is arranged at the outer end of the docking head 605, and a socket type suction pump 610 is arranged at the output end of the electric pushing seat 609. An adsorption seat 611 is arranged at the bottom end of the socket type suction pump 610, and an adsorption groove 612 is opened at the bottom end of the adsorption seat 611. A second hydraulic cylinder 7 is arranged at the right end of the top of the frame 1, and the output end of the second hydraulic cylinder 7 is connected to a pressing seat 8. Silicon steel sheets 9 are stacked at the outer end of the stacking assembly 3.

[0028] The specific operation is as follows. The staff passes the silicon steel sheet 9 to be prepared through the insertion joint 306, enabling the silicon steel sheets 9 to be stacked on the top of the first stacking seat 305. The outer contour dimension of the insertion joint 306 is consistent with the inner circle diameter of the silicon steel sheet 9, which enables the insertion joint 306 to position the silicon steel sheet 9. After the silicon steel sheets 9 are stacked, the second motor 4 works to drive the lead screw 5 to rotate, enabling the lead screw slider 602 to drive the lifting seat 601 to move downward, which enables the docking head 605 to move to a position where it docks with the insertion joint 306. Since the inner contour dimension of the docking head 605 is consistent with the outer contour dimension of the insertion joint 306, and the positions of the positioning groove 307 and the positioning hole 308 are consistent with the positions of the positioning block 606 and the positioning pile 607, this can effectively ensure the dimensional accuracy during the insertion process of the docking head 605 and the insertion joint 306. After the insertion joint 306 and the docking head 605 are inserted, the electric push seat 609 works, enabling the socket type suction pump 610 to drive the adsorption seat 611 to move downward and fit with the silicon steel sheet 9. By the operation of the socket type suction pump 610, the adsorption groove 612 can adsorb the silicon steel sheet 9. At this time, the second motor 4 works to drive the lead screw 5 to rotate reversely, which can drive the docking head 605 to move upward, enabling the adsorption seat 611 to drive the silicon steel sheet 9 to be sheared away from the stacked silicon steel sheets 9.

[0029] Please refer to Figures 1 to 7, the support component 2 includes a support base 201, a driving gear 202, a support plate 203 and a tooth groove 204. Support bases 201 are provided at both outer ends of the frame 1, and a driving gear 202 is arranged inside the frame 1. The support plate 203 passes through the frame 1 and the support bases 201, and tooth grooves 204 are formed on both outer sides of the support plate 203. The driving gear 202 meshes with the tooth groove 204, and the support plate 203 is displaced inside the support base 201 and the driving gear 202 by the rotation of the driving gear 202. When the lead screw 5 rotates, the lead screw slider 602 drives the lifting seat 601 to lift and lower. The first hydraulic cylinder 603 works to drive the lower push seat 604 to move downward. The docking head 605 and the shearing knife 608 are integrated, and the docking head 605 is sleeved with the socket type suction pump 610. The stacking component 3 includes a first motor 301, a rotating table 302, a support frame 303, a ball 304, a first stacking seat 305, a plug connector 306, a positioning groove 307, a positioning hole 308, a second stacking seat 309 and a positioning head 310. The output end of the first motor 301 is provided with a rotating table 302, and a support frame 303 is arranged on the outer side of the top of the rotating table 302. Balls 304 are arranged on the outer side of the bottom of the support frame 303. The first stacking seat 305 is arranged at the left end of the top of the support frame 303, and a plug connector 306 is arranged on the outer side of the top of the first stacking seat 305. A positioning groove 307 is formed at the outer end of the plug connector 306, and a positioning hole 308 is formed inside the plug connector 306. The second stacking seat 309 is arranged on the right side of the top of the rotating table 302, and a positioning head 310 is connected to the middle end inside the second stacking seat 309. Silicon steel sheets 9 are stacked at the outer end of the first stacking seat 305 and the inner end of the second stacking seat 309, and the first stacking seat 305 and the second stacking seat 309 are symmetrically distributed along the vertical center line of the rotating table 302. The inner contour dimension of the docking head 605 matches the outer contour dimension of the plug connector 306. The dimension of the positioning pile 607 matches the dimension of the positioning hole 308. The outer contour dimension of the socket type suction pump 610 matches the inner contour dimension of the second stacking seat 309. And the outer contour dimension of the pressing seat 8 matches the inner contour dimension of the second stacking seat 309;

[0030] The specific operation is as follows. After moving the adapter 605 back to its original position, by rotating the driving gear 202 to engage with the tooth groove 204, the support plate 203 can be driven to move to the bottom end of the adsorption seat 611. At this time, the electric push seat 609 drives the socket-type suction pump 610 to move upward, enabling the silicon steel sheet 9 to move to a position where it fits against the shearing knife 608. Then, the first hydraulic cylinder 603 operates to drive the adapter 605 downward, making the silicon steel sheet 9 fit against the top surface of the support plate 203. At this time, the first hydraulic cylinder 603 continues to apply pressure, and the shearing knife 608 can shear the silicon steel sheet 9. Through the structural design of the shearing assembly 6 and the displacement of the support assembly 2, the device can accurately position and shear the silicon steel sheet 9 in a very short time, which can greatly improve the preparation efficiency and accuracy of the stator assembly. After the silicon steel sheet 9 is sheared, the electric push seat 609 can drive the socket-type suction pump 610 to move upward again. At this time, the waste residue of the sheared silicon steel sheet 9 is pressed by the shearing knife 608 on the surface of the support plate 203. By moving the socket-type suction pump 610 upward, the adsorption seat 611 can apply an upward force to the silicon steel sheet 9. Through this operation, the situation where the sheared waste residue gets stuck at the shearing end of the silicon steel sheet 9 can be avoided. After the silicon steel sheet 9 is separated from the waste residue, the first hydraulic cylinder 603 retracts, causing the shearing knife 608 to separate from the support plate 203. At this time, the support plate 203 retracts, carrying the sheared waste residue of the silicon steel sheet 9 out of the outer end of the frame 1. Then, the mechanical claw or the staff outside the device can easily clean the waste residue without affecting the normal use of the device. After the support plate 203 moves back, by operating the electric push seat 609, the adsorption seat 611 can drive the silicon steel sheet 9 to move to a position below the horizontal plane of the shearing knife 608 again. At the same time, by driving the rotating table 302 to rotate with the first motor 301, the first stacking seat 305 and the second stacking seat 309 can be adjusted. Since the first stacking seat 305 and the second stacking seat 309 are symmetrically distributed along the vertical center line of the rotating table 302, the second stacking seat 309 can move to the original position of the first stacking seat 305. At this time, by driving the lifting seat 601 to move downward with the rotation of the lead screw 5, the adsorption seat 611 can drive the silicon steel sheet 9 to move into the second stacking seat 309. Since the inner contour of the adsorption seat 611 is the same as the outer contour size of the second stacking seat 309, and the outer contour of the positioning head 310 is the same as the shearing contour of the shearing knife 608, the adsorption seat 611 can position the silicon steel sheet 9 through the second stacking seat 309 and enable the silicon steel sheet 9 to smoothly enter its interior. The positioning of the silicon steel sheet 9 and the positioning head 310 can stack the silicon steel sheets 9 neatly in the second stacking seat 309. Since this positioning structure follows the positioning logic of the silicon steel sheet 9 shearing process and is all implemented by the shearing assembly 6, by incorporating the shearing and pressing of the silicon steel sheet 9 into the same step, the cumbersome repeated positioning can be eliminated, which can greatly improve the preparation efficiency of the device. After the silicon steel sheet 9 is placed inside the second stacking seat 309, the first motor 301 drives the rotating table 302 to rotate, enabling the second stacking seat 309 and the first stacking seat 305 to return to their original positions.At this time, the device can perform the step of the shearing component 6 sucking the silicon steel sheet 9 from the first stacking seat 305 again. After the second stacking seat 309 returns to its original position, the pressing seat 8 is driven by the second hydraulic cylinder 7 to move downward, so that the pressing seat 8 can be pressed into the second stacking seat 309. Through the structural design of the device, the silicon steel sheet 9 can be pressed against the already stacked silicon steel sheets 9 immediately after one silicon steel sheet 9 is stacked. This can avoid the situation of low pressing tightness of the silicon steel sheet 9 caused by poor conduction effect of the pressing force when a large number of silicon steel sheets 9 are stacked and then pressed together uniformly, which can effectively improve the pressing quality of the stator assembly. The use of the support frame 303 can improve the support effect of the rotating table 302, and the ball 304 can reduce the friction force received by the support frame 303 when the rotating table 302 rotates.,

[0031] In summary, for this manufacturing device of a motor stator assembly, during use, first, the staff passes the silicon steel sheet 9 to be prepared through the insertion joint 306, so that the silicon steel sheets 9 can be stacked on the top of the first stacking seat 305. The outer contour size of the insertion joint 306 is the same as the inner circle diameter of the silicon steel sheet 9, which enables the insertion joint 306 to position the silicon steel sheet 9. After the silicon steel sheets 9 are stacked, the second motor 4 works to drive the lead screw 5 to rotate, so that the lead screw slider 602 drives the lifting seat 601 to move downward, which enables the docking head 605 to move to a position where it docks with the insertion joint 306. Since the inner contour size of the docking head 605 is the same as the outer contour size of the insertion joint 306, and the positions of the positioning groove 307 and the positioning hole 308 are the same as the positions of the positioning block 606 and the positioning pile 607, this can effectively ensure the dimensional accuracy during the insertion process of the docking head 605 and the insertion joint 306;

[0032] Then, after the insertion joint 306 and the docking head 605 are inserted, the electric push seat 609 works, so that the socketed suction pump 610 drives the adsorption seat 611 to move downward to fit with the silicon steel sheet 9. By the work of the socketed suction pump 610, the adsorption groove 612 can adsorb the silicon steel sheet 9. At this time, the second motor 4 works to drive the lead screw 5 to rotate reversely, which can drive the docking head 605 to move upward, so that the adsorption seat 611 can drive the silicon steel sheet 9 to be sheared to separate from the stacked silicon steel sheets 9. After the docking head 605 moves back to its original position, by rotating the driving gear 202 to engage with the tooth groove 204, the support plate 203 can be driven to move to the bottom of the adsorption seat 611. At this time, the electric push seat 609 drives the socketed suction pump 610 to move upward, so that the silicon steel sheet 9 can move to a position where it fits with the shearing knife 608. And the first hydraulic cylinder 603 works to drive the docking head 605 to move downward, so that the silicon steel sheet 9 can fit with the top surface of the support plate 203. At this time, the first hydraulic cylinder 603 continues to apply pressure, and the shearing of the silicon steel sheet 9 by the shearing knife 608 can be realized. Through the structural design of the shearing component 6 and the displacement of the support component 2, the device can complete the precise positioning and shearing of the silicon steel sheet 9 in a very short time, which can greatly improve the preparation efficiency and preparation precision of the stator assembly;

[0033] Then, after the shearing of the silicon steel sheet 9 is completed, the electric push seat 609 can drive the socketed suction pump 610 to move upward again. At this time, the waste residue of the silicon steel sheet 9 cut out is pressed on the surface of the support plate 203 by the shearing knife 608. By moving the socketed suction pump 610 upward, the adsorption seat 611 can apply an upward force to the silicon steel sheet 9. Through this operation, the situation that the cut-out waste residue gets stuck at the shearing end of the silicon steel sheet 9 can be avoided. After the separation of the silicon steel sheet 9 from the waste residue is completed, the first hydraulic cylinder 603 retracts, which can separate the shearing knife 608 from the support plate 203. At this time, the support plate 203 retracts, and can carry the cut-out waste residue of the silicon steel sheet 9 out of the outer end of the frame 1. At this time, the mechanical claw or the staff outside the equipment can easily clean the waste residue without affecting the normal use of the equipment;

[0034] Subsequently, after the support plate 203 moves back, through the operation of the electric push seat 609, the adsorption seat 611 can drive the silicon steel sheet 9 to move to a position below the horizontal plane of the shearing knife 608 again. At the same time, by driving the rotating table 302 to rotate through the first motor 301, the first stacking seat 305 and the second stacking seat 309 can be adjusted in position. Since the first stacking seat 305 and the second stacking seat 309 are symmetrically distributed along the vertical center line of the rotating table 302, the second stacking seat 309 can move to the original position of the first stacking seat 305. At this time, by driving the lifting seat 601 to move downward through the rotation of the lead screw 5, the adsorption seat 611 can drive the silicon steel sheet 9 to move into the second stacking seat 309. Since the inner contour of the adsorption seat 611 is the same as the outer contour size of the second stacking seat 309, and the outer contour of the positioning head 310 is the same as the shearing contour of the shearing knife 608, the adsorption seat 611 can make the silicon steel sheet 9 smoothly enter its interior through positioning with the second stacking seat 309. And the positioning of the silicon steel sheet 9 and the positioning head 310 can make the silicon steel sheet 9 neatly stacked in the second stacking seat 309. Since this positioning structure follows the positioning logic of the shearing process of the silicon steel sheet 9 and is all implemented by the shearing assembly 6, by incorporating the shearing and pressing of the silicon steel sheet 9 into the same step, the cumbersome repeated positioning can be eliminated, which can greatly improve the preparation efficiency of the equipment;

[0035] Finally, after the silicon steel sheet 9 is placed inside the second stacking seat 309, the first motor 301 drives the rotating table 302 to rotate, which can make the second stacking seat 309 and the first stacking seat 305 return to their original positions. At this time, the equipment can perform the step of the shearing assembly 6 sucking the silicon steel sheet 9 from the first stacking seat 305 again. After the second stacking seat 309 returns to its original position, by driving the pressing seat 8 to move downward through the second hydraulic cylinder 7, the pressing seat 8 can be pressed into the second stacking seat 309. Through the structural design of the equipment, the silicon steel sheet 9 can be immediately pressed together with the already stacked silicon steel sheets 9 after stacking one silicon steel sheet 9. This can avoid the situation that the pressing tightness of the silicon steel sheet 9 is low due to the poor conduction effect of the pressing force when a large number of silicon steel sheets 9 are stacked and then uniformly pressed, which can effectively improve the pressing quality of the stator assembly.
