Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a device and method for shaping the lead wires of a motor stator winding. Background Technology

[0002] The motor stator is a crucial component of a motor, consisting of two main parts: the stator core and the windings. The windings are made of enameled wire, and the stator is formed by manually or mechanically embedding the windings into the core. Since the three sets of winding leads of the motor stator need to pass through three flat holes in the waterproof housing, the three sets of winding leads need to be shaped to align their positions with the three through-holes in the waterproof housing, facilitating the installation of the waterproof housing into the stator. Currently, the most common method is to manually bend and shape the winding leads. The drawbacks of this manual shaping are that the enameled wire in the stator windings is thick and difficult to bend; manual bending and shaping is labor-intensive; and the uneven stress on the enameled wire during bending and shaping can easily damage the enamel coating. Furthermore, manual shaping makes it difficult to ensure the consistency of the shape and position of the three sets of winding leads, and it also cannot guarantee a smooth installation of the waterproof housing into the stator. This manual stator winding lead shaping is time-consuming, labor-intensive, and inefficient, and the production quality of the motor cannot be guaranteed.

[0003] Therefore, in order to meet the current needs of motor production and to conveniently and efficiently shape the stator winding leads of the motor, a stator winding lead shaping device is needed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art by providing a motor stator winding lead wire shaping device and working method. The motor stator winding lead wire shaping device and working method has a simple structure and is easy to operate. By using the shaping hook and its various driving mechanisms, the stator winding lead wire can be automatically shaped.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The first objective of this invention is to provide a motor stator winding lead wire shaping device for shaping stator winding leads wires. The motor stator winding lead wire shaping device includes a base plate, a shaping hook, a stator rotation drive mechanism, a stator guide pin lifting mechanism, a shaping hook lifting mechanism, a shaping hook front and rear drive mechanism, a shaping hook twisting and bending mechanism, a limit baffle pushing mechanism, and a laser sensor mechanism.

[0007] Furthermore, the shaping hook torsion and folding mechanism is fixed on the base plate, and the shaping hook torsion and folding mechanism includes a rotary seat, the shaping hook is fixed on the rotary seat, and the shaping hook torsion and folding mechanism is used to drive the shaping hook to rotate.

[0008] Furthermore, the stator rotation drive mechanism is fixed on the substrate, and the stator rotation drive mechanism includes a positioning seat. The stator rotation drive mechanism is used to position and drive the stator to be shaped to rotate together.

[0009] Furthermore, the stator guide pin lifting mechanism is fixed on the base plate. The stator guide pin lifting mechanism includes a guide pin. The stator guide pin lifting mechanism is used to guide the stator during shaping and to lift the stator after shaping, thereby facilitating manual handling.

[0010] Furthermore, the shaping hook lifting mechanism is fixed on the base plate, and the shaping hook front and rear drive mechanism and the shaping hook twisting and bending mechanism are both connected to the shaping hook lifting mechanism. The shaping hook lifting mechanism is used to drive the shaping hook front and rear drive mechanism and the shaping hook twisting and bending mechanism to move up and down.

[0011] Furthermore, the front and rear drive mechanism of the shaping hook is fixed on the base plate, and the front and rear drive mechanism of the shaping hook is connected to the twisting and bending mechanism of the shaping hook. The front and rear drive mechanism of the shaping hook is used to drive the twisting and bending mechanism of the shaping hook to move back and forth.

[0012] Furthermore, the limiting baffle pushing mechanism is connected to the shaping hook twisting and bending mechanism, and the limiting baffle pushing mechanism includes a limiting baffle.

[0013] Furthermore, the laser sensor mechanism is fixed on the substrate, and the laser sensor mechanism includes a laser sensor for confirming whether the stator is correctly placed.

[0014] Furthermore, the shaping hook includes an integrally formed hook body and hook head, and the hook head of the shaping hook is a forked barb shape.

[0015] Furthermore, the shaping hook includes a lead wire limiting groove, a lead wire guiding opening, and a limiting plate guiding groove; the lead wire limiting groove is located inside the hook head of the shaping hook, the outer side of the hook head of the shaping hook is bent outward to form the lead wire guiding opening, and the limiting plate guiding groove is located on the hook body.

[0016] Furthermore, the width of the lead wire limiting groove is greater than the diameter of the winding lead wire, and two winding leads wires can enter the limiting groove in a single row. The lead wire guide opening is an angled opening or an arc opening, so as to facilitate the winding lead wires to be inserted into the lead wire limiting groove when the shaping hook rotates. The limiting plate guide groove is a groove for the limiting baffle to slide back and forth.

[0017] Furthermore, the hook head of the shaping hook must not have any sharp edges, and the contact surface must be smooth to prevent damage to the enameled wire during shaping.

[0018] Furthermore, the stator rotation drive mechanism also includes a positioning seat, a first hollow reducer, and a first servo motor.

[0019] Furthermore, the first hollow reducer is fixed on the base plate, the positioning seat is fixed on the first hollow reducer, and the input end of the first hollow reducer is connected to the output shaft of the first servo motor.

[0020] Furthermore, the positioning seat is used to position, place, and limit the stator; the conformal inner hole of the positioning seat positions and places the stator, and limits the stator in the circumferential direction, so that the stator rotates with the circumference of the positioning seat, thereby realizing the bending and shaping of the stator winding lead wire in its circumferential direction.

[0021] Furthermore, the turntable of the first hollow reducer has a hollow structure, which facilitates the passage of the positioning rod, guide pin, and bearing housing assembly of the stator guide pin lifting mechanism. The first servo motor is a servo motor using an absolute encoder, which sets the zero point position in the stator circumferential direction to achieve precise position control in the stator circumferential direction.

[0022] Furthermore, the stator guide pin lifting mechanism also includes a support column, a cylinder connecting plate, a first cylinder, a floating joint, a cam bearing follower, a positioning rod, a guide pin, and a bearing seat assembly; the stator guide pin lifting mechanism is fixed to the base plate by the support column, guides the stator during shaping, and lifts the stator after shaping, thereby facilitating manual handling.

[0023] Furthermore, the support column and the first cylinder are respectively fixed on both sides of the cylinder connecting plate. The piston rod of the first cylinder is connected to a floating joint, and two cam bearing followers are installed on the floating joint. The lower end of the positioning rod is engaged with the two cam bearing followers and passes through the bearing seat assembly fixed on the base plate. The positioning rod can slide up and down and rotate in the bearing seat assembly. The guide pin is installed on the positioning rod. When the first cylinder lifts the guide pin to the upper position, it is convenient to manually insert the stator. When it descends, it guides the stator into the positioning seat. When the first cylinder descends to the lower position, the guide pin supports the stator and limits the height position of the stator, which is the height position for the stator winding lead wire shaping. When the stator winding lead wire is shaped, the guide pin and the positioning rod rotate together with the positioning seat and the stator.

[0024] Furthermore, the shaping hook lifting mechanism includes a fixed base plate, a first guide shaft, a servo motor, a motor connecting plate, a second guide shaft, a first ball screw, a first screw support assembly, a first bearing, a coupling, a lifting plate, a first linear bearing, a third guide shaft, a second linear bearing, a photoelectric sensor, a detection plate, and a polyurethane gasket.

[0025] Furthermore, the shaping hook lifting mechanism is mounted below the base plate via its two first guide shafts, and drives the shaping hook front and rear drive mechanism and the shaping hook torsion and zigzag mechanism on it to move up and down via its four third guide shafts.

[0026] Furthermore, the fixed base plate is mounted below the base plate via a first guide shaft. The fixed base plate is connected to a motor connecting plate via four second guide shafts. The servo motor is fixed to the motor connecting plate. The lower end of the first ball screw is fixed to the fixed base plate via a first screw support assembly. The free side of the upper end of the first ball screw is connected to the base plate via a first bearing. The lower end shaft of the first ball screw and the servo motor shaft are connected by a coupling. The nut seat of the first ball screw is fixed to the lifting plate, thereby converting the rotational motion of the first ball screw into the up-and-down lifting motion of the lifting plate. Two first linear bearings are fixed to the lifting plate, and each first linear bearing is fitted onto a first guide shaft. Stable lifting of the lifting plate is achieved through the guidance of the two first guide shafts. Four third guide shafts are connected to the lifting plate. The axis passes through the second linear bearing fixed on the base plate, and through the third guide shaft, it can lift the guide rail base plate of the front and rear drive mechanism of the shaping hook, realizing the lifting function of its components. The photoelectric sensor is fixed on the fixed base plate, and the detection plate is fixed on the lifting plate. When the detection plate rises and disengages from the photoelectric sensor slot, the photoelectric sensor gives a signal, and the lifting plate stops rising, which is set as the limit position of the lifting mechanism of the shaping hook. The polyurethane gasket is sleeved on the third guide shaft and placed under the guide rail base plate. The polyurethane gasket must be elastic to buffer and dampen vibration, and prevent the guide rail base plate from suddenly falling and hitting the second linear bearing. The servo motor is a servo motor with an absolute encoder and has a brake function to prevent the lifting mechanism of the shaping hook from rapidly descending under gravity in case of abnormalities such as power failure, which could damage the shaping hook and the stator to be shaped.

[0027] Furthermore, the front and rear drive mechanism of the shaping hook includes a guide rail base plate, a linear guide rail, a second ball screw, a fixed side support, a supporting side support, a second screw support assembly, a second bearing, a motor mounting plate, a third servo motor, a driving pulley, a driven pulley, and a synchronous belt.

[0028] Furthermore, the front and rear drive mechanism of the shaping hook is fixed to the four third guide shafts of the shaping hook lifting mechanism through the guide rail base plate, and moves up and down with the shaping hook lifting mechanism, and drives the shaping hook torsion and zigzag mechanism to move back and forth on the linear guide rail.

[0029] Furthermore, the guide rail base plate is fixed to the four third guide shafts of the shaping hook lifting mechanism, and can move up and down with the third guide shafts. Two linear guide rails are fixed to the guide rail base plate, and the two linear guide rails are on both sides of the second ball screw. The two linear guide rails are parallel to the second ball screw in the axial movement direction, and their center lines are consistent with the center line of the second ball screw. The fixed side support and the supporting side support are fixed to the front and rear ends of the guide rail base plate. The positioning holes of the fixed side support and the supporting side support are concentric with the second ball screw in the axial movement direction, ensuring that the second ball screw is parallel to the two linear guide rails after installation. The short axis side of the second ball screw is connected to the supporting side support through the second bearing, and the long axis side of the second ball screw is connected to the fixed side support through the second screw support assembly. The second ball screw's nut seat is connected to the nut connecting block of the shaping hook torsion and zigzag mechanism via a side support connection. A driven pulley is fixed on the long shaft of the second ball screw. The driven pulley drives the second ball screw's lead screw to rotate, thus converting the rotational motion of the second ball screw's lead screw into the linear motion of the second ball screw's nut seat, realizing the reciprocating motion of the shaping hook torsion and zigzag mechanism on it. The third servo motor is a servo motor with an absolute encoder, using a folding method, and is fixed on the motor mounting plate on the side of the guide rail base plate. The synchronous belt is connected to the driving pulley and the driven pulley respectively. The tension of the synchronous belt can be adjusted through the motor mounting plate. The output shaft of the third servo motor is equipped with a driving pulley, and power output is achieved through the driving pulley and the synchronous belt.

[0030] Furthermore, the front and rear drive mechanism of the shaping hook also includes a sensor bracket, a proximity sensor, and a belt protective cover.

[0031] Furthermore, the sensor bracket is fixed to the guide rail base plate, the proximity sensor is fixed to the sensor bracket, and the belt protective cover is placed on the motor mounting plate.

[0032] Furthermore, the shaping hook torsion and bending mechanism also includes a torsion bracket, a nut connecting block, a second hollow reducer, a fourth servo motor, a rotary seat, and a bushing.

[0033] Furthermore, the shaping hook torsion folding mechanism drives the shaping hook to rotate and can move back and forth on the linear guide rail of the front and rear driving mechanism of the shaping hook to achieve the shaping of the torsion folding line of the winding lead wire.

[0034] Furthermore, the base plate of the torsion bracket is connected to the linear guide rail of the front and rear drive mechanism of the shaping hook. The nut connecting block installed under the base plate of the torsion bracket is connected to the nut seat of the second ball screw of the front and rear drive mechanism of the shaping hook. When the screw of the second ball screw rotates, the torsion zigzag mechanism of the shaping hook reciprocates back and forth. The second hollow reducer is fixed on the vertical plate of the torsion bracket. The fourth servo motor connected to the second hollow reducer is installed on the side of the second hollow reducer. It is a fourth servo motor with an absolute encoder. The turntable of the second hollow reducer has a hollow structure so that the bushing can pass through the middle hole. The rotary seat is fixed on the second hollow reducer. The bushing is installed on the rear end face of the rotary seat. The bushing and the rotary seat rotate together with the second hollow reducer.

[0035] Furthermore, the limiting baffle pushing mechanism includes a cylinder bracket, a second cylinder, a floating joint, a fixing ring, a connecting sleeve, and a limiting baffle.

[0036] Furthermore, the limiting baffle pushing mechanism pushes the limiting baffle forward, and the limiting winding lead wire is in the groove of the shaping hook.

[0037] Furthermore, the second cylinder is mounted on a cylinder bracket, which is fixed to the base plate of the torsion bracket. The piston rod of the second cylinder is connected to a floating joint, and a fixed ring is fixed to the floating joint. One end of the connecting sleeve is inserted into the hole of the fixed ring and can rotate within the fixed ring. The connecting sleeve passes through the guide groove of the bushing of the shaping hook torsion folding mechanism and can slide within the guide groove of the bushing. A limiting baffle is fixedly connected to the front end of the connecting sleeve. The limiting baffle passes through the guide groove of the limiting plate of the shaping hook and can slide within the guide groove of the limiting plate. When the second cylinder extends, the limiting baffle pushes out to limit the two leads of the winding to be arranged in a single row and parallel within the hook head of the shaping hook. When the shaping hook drives the winding leads to be shaped, the connecting sleeve and the limiting baffle rotate together with the rotary seat of the shaping hook torsion folding mechanism.

[0038] Furthermore, the laser sensor mechanism also includes a sensor mount and a laser sensor.

[0039] Furthermore, the laser sensor mechanism is fixed on the substrate to detect the lower reference stop of the stator and confirm whether the stator is correctly placed.

[0040] Furthermore, the sensor base is fixed on the substrate, the laser sensor is fixed inside the sensor base, and the wires run through the inner hole of the sensor base into the power distribution cabinet below to prevent the laser sensor from being damaged when the stator is manually picked up or placed. After the stator to be shaped is placed into the positioning seat by the operator, the laser sensor gives a detection signal to start detecting the lower reference stop of the stator. Only after the detection confirms that the stator has been correctly placed in place can the next step of shaping the stator winding lead wires begin.

[0041] Furthermore, the stator to be shaped includes stator winding leads and a reference stop. The stator winding leads include three sets of winding leads, namely the first winding lead, the second winding lead, and the third winding lead. The first winding lead, the second winding lead, and the third winding lead each include two winding leads.

The lead wire of the rotating winding of the shaping hook is inserted into the shaping hook, so that the two lead wires of the winding are arranged in a single row and limited in the shaping hook. The shaping hook drives and guides the lead wire of the winding. Through the linkage of the X-axis, Z-axis, A-axis and C-axis, the shaping work of the lead wire of the winding is automatically completed.

[0047] S5. The stator slewing drive mechanism rotates to the other stator winding lead-out shaping position, repeats step S4, and automatically completes the shaping work of the other winding leads-out.

[0049] S7. Manually remove the stator. The stator reshaping is complete. Repeat this process to reshape the next stator.

[0050] Furthermore, the movement of the shaping hook in the X-axis direction is achieved through the shaping hook torsion and broken line mechanism, the movement in the Z-axis direction is achieved through the shaping hook lifting mechanism, and the rotation in the A-axis direction is achieved through the shaping hook torsion and broken line mechanism; the rotation of the stator in the C-axis direction is achieved through the stator rotary drive mechanism, and the movement in the Z-axis direction is achieved through the stator guide pin lifting mechanism.

[0051] Furthermore, the working method of the motor stator winding lead shaping device specifically includes the following steps:

[0052] S1. When the guide pin is in the upper position, it is in the initial position. The stator is manually placed in the stator. The guide pin descends and guides the stator into the positioning seat. When the guide pin is in the lower position, the guide pin supports the stator and keeps the stator height position unchanged.

[0053] S2. The laser sensor detects the standard stop of the stator to confirm that the stator is correctly placed.

[0054] S3. The stator rotary drive mechanism rotates to the first winding lead-out shaping position;

[0055] S4. The shaping hook descends and moves forward to its position.

The shaping hook drives and guides the lead wires of the winding. Through the linkage of the X-axis, Z-axis, A-axis and C-axis, the shaping work of the first lead wire of the winding is automatically completed.

[0056] S5. The stator rotary drive mechanism rotates to the second winding lead-out shaping position;

[0057] S6. The shaping hook descends and moves forward to its position. The second winding lead wire is inserted into the shaping hook, so that the two winding leads wires are arranged in a single row and limited in the shaping hook. The shaping hook drives and guides the winding leads wires. Through the linkage of the X-axis, Z-axis, A-axis and C-axis, the shaping work of the second winding lead wire is automatically completed.

[0058] S7. The stator rotary drive mechanism rotates to the third winding lead-out shaping position;

[0059] S8. The shaping hook descends and moves forward to its position.

When it descends, it guides the stator into the positioning seat 301. When the first cylinder 403 lowers the guide pin 408 to the lower position, the guide pin 408 supports the stator and limits the height position of the stator, which is the height position for the stator winding lead wire shaping. During the stator winding lead wire shaping, the guide pin 408 and the positioning rod 406 rotate together with the positioning seat 301 and the stator.

[0103] The shaping hook lifting mechanism 5 includes a fixed base plate 501, a first guide shaft 502, a servo motor 503, a motor connecting plate 504, a second guide shaft 505, a first ball screw 506, a first screw support assembly 507, a first bearing 508, a coupling 509, a lifting plate 510, a first linear bearing 511, a third guide shaft 512, a second linear bearing 513, a photoelectric sensor 514, a detection plate 515, and a polyurethane washer 516.

[0104] The shaping hook lifting mechanism 5 is mounted below the base plate 1 via its two first guide shafts 502, and drives the shaping hook front and rear drive mechanism 6 and the shaping hook twisting and bending mechanism 7 to move up and down via its four third guide shafts 512.

[0105] A fixed base plate 501 is mounted below the base plate 1 via a first guide shaft 502. The fixed base plate 501 is connected to a motor connecting plate 504 via four second guide shafts 505.

Shaft 503 is connected by coupling 509. The nut seat of the first ball screw 506 is fixed on the lifting plate 510, thereby converting the rotational motion of the first ball screw 506 into the up-and-down lifting motion of the lifting plate 510. Two first linear bearings 511 are fixed on the lifting plate 510, and the two first linear bearings 511 are respectively sleeved on two first guide shafts 502. Stable lifting of the lifting plate 510 can be achieved by guiding the two first guide shafts 502. Four third guides are connected to the lifting plate 510. The third guide shaft 512 passes through the second linear bearing 513 fixed on the base plate 1. The third guide shaft 512 can lift the guide rail base plate 601 of the shaping hook front and rear drive mechanism 6, realizing the lifting function of its components. The photoelectric sensor 514 is fixed on the fixed base plate 501, and the detection plate 515 is fixed on the lifting plate 510. When the detection plate 515 rises and disengages from the slot of the photoelectric sensor 514, the photoelectric sensor 514 gives a signal, and the lifting plate 510 stops rising, thus setting it to shaping mode. At the extreme position of the hook lifting mechanism 5, the polyurethane washer 516 is fitted on the third guide shaft 512 and placed under the guide rail base plate 601. The polyurethane washer 516 must be elastic to buffer and dampen vibration, and prevent the guide rail base plate 601 from suddenly falling and hitting the second linear bearing 513. The servo motor 503 is a servo motor with an absolute encoder and has a brake function to prevent the shaping hook lifting mechanism 5 from rapidly descending under gravity in case of abnormalities such as power failure, which could damage the shaping hook 2 and the stator to be shaped.

The short shaft side of the second ball screw 603 is connected to the supporting side support 605 through the second bearing 607, and the long shaft side of the second ball screw 603 is connected to the fixed side support 605 through the second screw support assembly 606.

A driven pulley 611 is fixed on the long shaft of the second ball screw 603. The driven pulley 611 drives the screw of the second ball screw 603 to rotate, thereby converting the rotational motion of the screw of the second ball screw 603 into the linear motion of the nut seat of the second ball screw 603, realizing the forward and backward movement of the shaping hook torsion and zigzag mechanism 7 on it. In the reciprocating motion, the third servo motor 609 is a servo motor with an absolute encoder. It adopts a folding method and is fixed on the motor mounting plate 608 on the side of the guide rail base plate 601. The synchronous belt 612 is connected to the driving pulley 610 and the driven pulley 611 respectively. The tension of the synchronous belt 612 can be adjusted through the motor mounting plate 608.

[0113] The base plate of the torsion bracket 701 is connected to the linear guide rail 602 of the front and rear drive mechanism 6 of the shaping hook. The nut connecting block 702 installed under the base plate of the torsion bracket 701 is connected to the nut seat of the second ball screw 603 of the front and rear drive mechanism 6 of the shaping hook. When the screw of the second ball screw 603 rotates, the torsion zigzag mechanism 7 of the shaping hook moves back and forth. The second hollow reducer 703 is fixed on the vertical plate of the torsion bracket 701. The fourth servo motor 704 connected to the second hollow reducer 703 is installed on the side of the second hollow reducer 703. The fourth servo motor 704 adopts an absolute encoder.

The front end of the connecting sleeve 805 is fixedly connected to the limiting baffle 806. The limiting baffle 806 passes through the limiting plate guide groove 203 of the shaping hook 2 and can slide in the limiting plate guide groove 203. When the second cylinder 802 extends, the limiting baffle 806 is pushed out to limit the two leads of the winding in a single row in the hook head of the shaping hook 2.

The laser sensor 902 is routed through the inner hole of the sensor base 901 into the power distribution cabinet below to prevent the laser sensor 902 from being damaged when the stator is manually handled. After the stator to be shaped is placed into the positioning seat 301, the laser sensor 902 gives a detection signal to start detecting the lower reference stop of the stator. Only after the detection confirms that the stator has been correctly placed in place can the next step of shaping the stator winding lead wires begin.
