Description

Technical Field

[0001] This invention relates to rotor core assembly, specifically to a modular automatic assembly device for frequency converter rotors. Background Technology

[0002] The rotor core is one of the core components of a motor, and its assembly quality directly affects the motor's performance, efficiency, and service life. In the production process of variable frequency motor rotors, especially modular rotors, multiple components such as the oil slinger cap, auxiliary balance block, core, upper baffle, and main balance block are usually precisely stacked and fixed with rivets.

[0003] Currently, the industry mostly uses manual or semi-automatic equipment to assemble such rotors. Manual assembly is not only inefficient and labor-intensive, but also susceptible to factors such as the operator's skill level and fatigue, making it difficult to guarantee the accuracy and consistency of product assembly. This can easily lead to problems such as component misalignment, omissions, and poor riveting, resulting in unstable product quality.

[0004] While some existing semi-automatic equipment can replace some manual operations, the connections between different processes are not smooth, and the degree of automation and integration is not high. A lot of manual intervention is still required for loading and unloading, positioning, and inter-process transfer, which cannot achieve continuous and efficient automated production. This restricts the further improvement of production efficiency and capacity, and also increases labor costs and management difficulty.

[0005] Therefore, there is an urgent need for equipment capable of high-precision, automated assembly of rotor cores throughout the entire process, to address the problems of low production efficiency, high reliance on manual labor, and difficulty in ensuring product consistency in existing technologies.

[0020] The following description, in conjunction with the accompanying drawings, further illustrates the automatic modular assembly device for frequency converter rotors according to the present invention.

[0021] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] See Figures 1-19 As shown, a variable frequency rotor modular automatic assembly device includes a conveying mechanism 1 and a tray 2 placed on the conveying mechanism 1; characterized in that it also includes an oil slinger 3 for automatically feeding oil slinger caps onto the tray 2; The pallet 2 includes a pallet base plate 21, a pallet base 22 mounted on the pallet base plate 21, a positioning seat 23 mounted on the pallet base 22, a lifting seat 24 that can be raised and lowered and mounted inside the pallet base 22, a plurality of push rods 25 mounted on the lifting seat 24 to limit the position of the rotor component assembled on the positioning seat 23, a locking member 26 mounted on the pallet base 22 to limit the position of the lifting seat 24 on the pallet base 22, and a locking groove 27 provided on the lifting seat 24 that is adapted to the locking member; Locking component 26 includes a locking seat 261 mounted on the tray base 22, a locking rod 262 slidably mounted in the locking seat 261, a limiting platform 263 disposed on the locking rod 262, and a spring 264 installed between the locking seat 261, the limiting platform 263 and the locking rod 262 for pushing the locking rod 262 to reset. The locking element 26 and locking groove 27 are used to lock the position of the lifting seat 24 on the tray base 22. The spring force of the spring 264 pushes the limiting platform 263 of the locking rod 262, which pushes the locking rod 262 forward, causing the front end of the locking rod 262 to be locked in the locking groove 27 of the lifting seat 24, thus limiting the position of the lifting seat 24. The front end of the locking element 26 is set in an arc shape. When the top rod 25 is subjected to downward pressing force or the lifting seat 24 is subjected to upward pushing force, the locking groove 27 contacts the arc end of the locking element 26, and the locking element 26 is pressed backward to compress the spring 264, so that the locking element 26 is disengaged from the locking groove 27, and the lifting seat 24 can move up and down. The oil-sling cap feeding machine 3 includes an oil-sling cap feeding frame 31, a motor 32 mounted on the oil-sling cap feeding frame 31, a rotating disk 33 connected to and driven by the motor 32, several oil-sling cap rods 34 mounted on the rotating disk 33 for stacking several oil-sling caps and limiting the position of the oil-sling caps, an oil-sling cap support seat 35 movably mounted on the oil-sling cap rods 34, a lifting mechanism 36 mounted on the oil-sling cap feeding frame 31 for pushing the oil-sling cap support seat 35 upward and causing several oil-sling caps stacked on the oil-sling cap support seat 35 to move upward along the oil-sling cap rods 34 to the picking position, a feeder 37 mounted on the oil-sling cap feeding frame 31, and an adjustment mechanism 38 mounted on the oil-sling cap feeding frame 31 for detecting and adjusting the circumferential position of the oil-sling caps; The lifting mechanism 36 includes a driver 361 mounted on the oil slinger cap loading rack 31 and a lifting member 362 mounted on the driver 361 and driven by the driver 361 to move upward; the driver 361 can be any of a cylinder, a hydraulic cylinder or a servo transmission system. The feeder 37 includes a vertical frame 371 mounted on the oil-slinger cap feeding rack 31, a horizontal servo drive mechanism 372 mounted on the vertical frame 371, a crossbeam frame 373 slidably mounted on the crossbeam and driven by the horizontal servo drive mechanism 372 to move laterally on the crossbeam, a vertical servo drive mechanism 374 mounted on the crossbeam frame 373, a gripping frame 375 mounted on the vertical servo drive mechanism 374, gripping cylinders 376 mounted at both ends of the gripping frame 375, and grippers 377 mounted on the gripping cylinders 376; the gripping cylinder 376 on one side of the gripping frame 375 is used to move the oil-slinger cap on the oil-slinger cap rod 34 to the oil-slinger cap positioning seat 383, and the gripping cylinder 376 on the other side is used to move the positioned oil-slinger cap to the positioning seat 23 on the tray 2. The two are carried out simultaneously, which can save transfer and feeding time and speed up production efficiency. The adjustment mechanism 38 includes an adjustment frame 381 mounted on the oil slinger cap loading rack 31, an adjustment driver 382 mounted on the adjustment frame 381, an oil slinger cap positioning seat 383 mounted on the adjustment driver 382 and rotated by the adjustment driver 382 to adjust the circumferential position of the oil slinger cap, and an oil slinger cap sensor 384 mounted on the adjustment frame 381 for detecting the circumferential position of the oil slinger cap; the adjustment driver 382 can be any other rotary driver 361 such as a motor 32 or a rotary cylinder; With the setup of this device, operators only need to place the various components of the rotor core into the corresponding racks or silos, and the device can automatically complete the assembly of the rotor core without manual assembly. It has a high degree of automation, which improves production efficiency while reducing the intensity of manual labor, reducing labor requirements, and saving costs. The positioning seat 23 on the tray 2, the lifting plate and several top rods 25 on the lifting plate limit the position of each rotor component on the tray 2, ensuring that each rotor component can be accurately assembled on the positioning seat 23. By setting the oil-slinging cap feeding machine 3, the oil-slinging cap is automatically and accurately installed onto the positioning seat 23 of the tray 2 and the hole on the oil-slinging cap is precisely fitted onto the top rod 25. When loading oil-slinging caps: The operator stacks several oil-slinging caps on the oil-slinging cap feeder 34. The motor 32 drives the rotating disk 33 to rotate, and the rotating disk 33 drives several oil-slinging cap feeder 34 to rotate. When the oil-slinging cap feeder 34 rotates to the picking position, the controller controls the horizontal servo drive mechanism 372 to drive the crossbeam frame 373 and the vertical servo drive mechanism 374 to move to the set position. The vertical servo drive mechanism 374 drives the clamping frame 375 and the gripper 377 to move downward to the loading position. Then, the clamping cylinder 376 controls the gripper 377 to clamp the oil-slinging cap. After that, the horizontal servo drive mechanism 372 and the vertical servo drive mechanism 374 drive it to move to the oil-slinging cap positioning seat 383 of the adjusting mechanism 38 and place it on the oil-slinging cap positioning seat 383. At this time, the control driver 361 drives the lifting component 362 to move upward, and the lifting component 362 pushes the stacked oil slinger caps to move upward one station, so that the topmost oil slinger cap moves to the loading position. At the same time, the controller controls the adjustment driver 382 to drive the oil slinger positioning seat 383 and the oil slinger to rotate. When the oil slinger sensor 384 detects the notch in the oil slinger, it sends a signal to the controller. The controller controls the adjustment driver 382 to stop moving and controls the clamping cylinder 376 installed at the other end of the clamping frame 375 to drive the clamping claw 377 to clamp the positioned oil slinger and install it on the positioning seat 23, so that the hole on the oil slinger fits on the top rod 25.

[0024] In one embodiment, the system further includes several lifting mechanisms 4 mounted on the conveying mechanism 1 for lifting the pallet 2 upwards and disengaging it from the conveying mechanism 1. Each lifting mechanism 4 includes a lifting frame 41 mounted on the conveying mechanism 1, a lifting device 42 mounted on the lifting frame 41, a top plate 43 connected to the lifting device 42, and several positioning posts 44 mounted on the top plate 43. The pallet bottom plate 21 is provided with several positioning holes 46 that are adapted to the positioning posts 44. Sensors are provided on the conveying mechanism 1, along with the lifting mechanisms 4 and the assembly position of each process, for sensing whether the pallet 2 has moved to the assembly position. The lifting device 42 can be any other linear actuator 361, such as a pneumatic cylinder, a hydraulic cylinder, or an electric actuator. With the lifting mechanism 4 in place, when the pallet 2 moves to the assembly position of each component, the lifting mechanism 4 lifts the pallet 2 from the conveying mechanism 1, so that it is separated from the conveying mechanism 1 for loading and assembly. By setting a number of positioning posts 44 on the top plate 43 and a number of positioning holes 46 on the bottom plate 21 of the pallet, the positioning posts 44 and positioning holes 46 limit the position of the pallet 2 and the position of the positioning seat 23 on the pallet 2, so as to avoid the position of the positioning seat 23 and the number of top rods 25 from deviating and causing misalignment of the component assembly.

[0025] In one embodiment, it also includes a balance block feeder that automatically feeds balance blocks onto the tray 2, the balance block feeder including a secondary balance block feeder 5 and a main balance block feeder 51; Both the auxiliary balance block feeder 5 and the main balance block feeder 51 include a balance block feeder frame 52, a material storage rack 53 slidably mounted on the balance block feeder frame 52, a drive cylinder 54 mounted on the balance block feeder frame 52 for driving the material storage rack 53 to move on the balance block feeder frame 52, several material seats 55 set on the material storage rack 53, and a limiting guide cage 56 mounted on the material seats 55 for stacking balance blocks and limiting the stacking position, which is composed of several limiting rods 622. By setting the limiting guide cage 56, the placement positions of the auxiliary balance block and the main balance block are limited by several limiting rods 622, so that their placement positions are consistent with the feeding and assembly positions, and ensure that the holes on the auxiliary balance block and the main balance block can be accurately fitted onto the top rod 25. The balance block feeding frame 52 is also equipped with a balance block lifting device 57 for lifting the balance blocks stacked in the limiting guide cage 56 to the feeding position, and a push rod 25 installed on the balance block lifting device 57. The material seat 55 is provided with a through hole 59 corresponding to the push rod 25, through which the push rod 25 can pass. The balance block lifting device 57 can be any of the other linear actuators 361 such as a cylinder or a hydraulic cylinder. The uppermost position of the limit guide cage 56 is set as the loading position of the balance block. After the balance block at the uppermost loading position is grabbed, the balance block driver 361 is controlled to drive the top rod 25 through the through hole 59 on the material seat 55 and push the stacked balance blocks to move upward one station, so that the uppermost balance block moves to the loading position and waits to be grabbed. It also includes a sensor frame 510 installed on the material storage rack 53 and a plurality of balance block sensors 511 installed on the sensor frame 510 corresponding to a plurality of limit guide cages 56; The balance block sensor 511 senses whether there is a balance block at the loading position of the limit guide cage 56 and sends a signal to the controller. When the balance block at the loading position is grabbed, the controller controls the balance block lifter 57 to start, pushing several balance blocks upward until the balance block at the top position is sensed by the balance block sensor 511. The top balance block is then in the loading position, and a signal is sent to the controller. The controller then controls the balance block lifter 57 to stop.

[0026] It also includes a balance block upright 512 mounted on the balance block feeding frame 52, a transverse servo drive mechanism mounted on the balance block upright 512, a crossbeam 373 driven by the transverse servo drive mechanism 372 to move laterally, a longitudinal driver 513 mounted on the crossbeam 373, a balance block clamping cylinder 514 mounted on the longitudinal driver 513, and a balance block gripper 515 mounted on the balance block clamping cylinder 514. During the loading of the secondary and primary balance blocks: the operator stacks several balance blocks into several limit guide cages 56 according to the set placement position. The controller controls the drive cylinder 54 to drive the material storage rack 53 forward to the set position. The set position can be controlled by the controller, or a sensor can be installed on the balance block loading frame 52 to sense the extension distance of the drive cylinder 54 or the upper limit guide cage 56 of the material storage rack 53. At this time, the first row of limit guide cages 56 is in the loading position, and then the controller controls the horizontal servo drive mechanism 37. 2. The longitudinal servo drive mechanism 374 drives the balance block clamping cylinder 514 and the balance block gripper 515 to move to the set position. After the balance block clamping cylinder 514 drives the balance block gripper 515 to clamp the balance block in the loading position, the controller controls the longitudinal servo drive mechanism 374 to drive the balance block gripper 515 to reset the balance block. Then, the controller controls the transverse servo drive mechanism 372 to move the balance block to the stator tray 2 and place the balance block on the positioning seat 23 or the iron core and reset it to perform the gripping of the next balance block. When the balance block in the loading position is grabbed, the balance block sensor 511 does not detect that there is a balance block in the loading position and sends a signal to the controller. The controller controls the balance block lifter 57 located below the limit guide cage 56 to start. The balance block lifter 57 drives the push rod 25 to pass through the through hole 59 and pushes the balance block to move upward until the balance block sensor 511 detects that there is a balance block in the loading position. Once all the balance blocks in the limiting guide cage 56 have been grabbed, the controller will move to the second limiting guide cage 56 in the same row to grab the balance blocks again. This process continues until all the balance blocks in the same row of limiting guide cages 56 have been grabbed. Then, the controller will control the drive cylinder 54 to move the material storage rack 53 forward by one station, so that the second row of limiting guide cages 56 can be moved to the loading position for material retrieval.

The vertical servo drive mechanism 374 drives the clamping frame 375 and the gripper 377 to move downward to the feeding position. Then, the controller controls the clamping cylinder 376 to drive the gripper 377 to clamp the upper baffle. After that, the horizontal servo drive mechanism 372 and the vertical servo drive mechanism 374 drive it to move to the upper baffle positioning seat 753 of the adjustment mechanism 38 and place it on the upper baffle positioning seat 753.

[0029] In one embodiment, it further includes a rivet feeder 8 that automatically and accurately inserts rivets into the iron core; the rivet feeder 8 is configured to automatically and accurately insert rivets into the rivet holes of the rotor assembly. The rivet feeding machine 8 includes a rivet feeding machine frame 81, a rivet feeding frame 82 placed on the rivet feeding machine frame 81, a rivet feeding seat 83 slidably installed on the rivet feeding frame 82, a rivet feeder 84 installed on the rivet feeding frame 82 for moving the rivet feeding seat 83, a rivet hopper 85 set on the rivet feeding machine frame 81 and located on both sides of the rivet feeding frame 82, a linear vibrator 86 set in the rivet hopper 85, a rivet conveying channel 87 installed on the linear vibrator 86, and a rivet lifter 88 set in the rivet hopper for lifting the rivets in the rivet hopper to the rivet conveying channel 87. The rivet conveying channel 87 is connected to the rivet feeding frame 82, and the rivet feeding seat 83 is provided with a rivet groove 831 that is compatible with the rivet.

The rivet lifter 882 drives the lifting frame 881 upward, which in turn moves several lifting plates 883 upward. As the lifting plates 883 move upward, they carry the rivets that have fallen onto them upward until they reach their highest point. Then, the rivets fall into the feed trough along the inclined part of the upper part of the lifting plate 883 and the inclined surface of the upper part of the hopper. The rivets in the feed trough are then conveyed forward by the linear vibrator 86. When the rivets move forward into the rivet slot 831 of the rivet feeder 83, the rivet feeder 84 is activated. The rivet feeder 84 pushes the rivet feeder 83 forward to the set position, and then the rivet lifting cylinder is activated, pushing the rivet lifting block upward. When the rivet is moved to the set position, the rivet lifting block pushes the rivet upward to the set position. Then, the horizontal servo drive mechanism 372 and the vertical servo drive mechanism 374 are activated to actuate the rivet clamping cylinder 814 and the rivet clamping claw 815 to clamp the rivet and insert it into the anchor hole of the rotor assembly to complete the rivet assembly. When the rivet is inserted into the anchor hole, the bottom of the rivet first contacts the top of the top rod 25. During the process of driving the rivet downward, a downward squeezing force is formed on the top rod 25 and the lifting seat 24. After being subjected to the downward squeezing force, the lifting seat 24 drives the locking groove 27 to squeeze the locking member 26. The locking member 26 compresses the spring 264 backward and retracts. After the locking member 26 is disengaged from the locking groove 27, the lifting seat 24 drives the top rod 25 to move downward, and the rivet is inserted into the anchor hole to complete the rivet assembly.

The pallet 2 is conveyed by the conveyor motor 15 driving the sprocket to rotate, which in turn drives the conveyor chain 626 to move, thereby conveying the pallet 2 on the conveyor chain 626. It also includes a push rod reset mechanism 10 installed on the conveying mechanism 1 for pushing the lifting seat 24 and the push rod 25 upward. The push rod reset mechanism 10 includes a limit cylinder 101 installed on the upper conveying frame 11, a limit plate 102 installed on the limit cylinder 101 to limit the upward movement height of the tray 2, a reset cylinder 103 installed on the upper conveying frame 11, and a reset member 104 installed on the reset cylinder 103 for pushing the lifting seat 24 upward. After the assembled rotor is removed, the tray 2 moves to the top rod reset mechanism 10, and the reset cylinder 103 and the limit cylinder 101 are activated. The limit cylinder 101 extends the limit plate 102, and the reset cylinder 103 drives the reset component 104 to move upward. After the reset component 104 passes through the tray 2, it contacts the lifting seat 24 and forms an upward pressing force. After the tray 2 is blocked by the limit plate 102, the lifting seat 24 is pushed upward by the continuous lifting force of the reset component 104. After the lifting seat 24 moves upward to the set position, the locking component 26 is pushed into the locking groove 27 by the reset force of the spring 264. The top rod 25 is reset after the locking component 26 is locked into the locking groove 27.

The hoisting frame 92 is movably mounted with a synchronous pulley, a synchronous belt motor 32 connected to the synchronous pulley for driving the synchronous pulley to rotate, and a synchronous belt mounted on the synchronous pulley; The transfer mechanism 9 is used to transfer the pallet 2 between the upper conveyor frame 11 and the lower conveyor frame 12, thereby forming a rotary device with the upper conveyor frame 11, the lower conveyor frame 12 and the transfer mechanism 9, so that the pallet 2 can be automatically circulated and transported. When the transfer mechanism 9 moves the pallet 2 up and down, it activates the lifting driver 93. When the lifting driver 93 moves the pull rod 96 upward, the lifting belt 95, which is in contact with the pull rod 96, is not under the tension of the pull rod 96. Instead, it moves upward with the pull rod 96 due to the gravity of the lifting frame 92. The lifting frame 92 then moves the pallet 2 downward. After the pallet 2 moves downward into position, the synchronous belt motor 32 installed on the lifting frame 92 is activated. The synchronous belt motor 32 drives the synchronous belt pulley to rotate, which in turn drives the synchronous belt to move. The synchronous belt then moves the pallet 2 out of or into the lifting frame 92. Sensors can be installed inside the lifting frame 92 and at the outlet of the lifting frame 92 to sense the pallet 2 and send signals to the controller to control the opening and closing of the transfer mechanism 9 and the conveying mechanism 1. When the lifting drive 93 moves the pull rod 96 downward, the pull rod 96 exerts a downward compressive force on the lifting belt 95. After being subjected to the compressive force, the other end of the lifting belt 95 pulls the lifting frame 92 upward, and the lifting frame 92 then moves the tray 2 upward.
