Technical Field

[0001] This invention relates to the field of motor assembly technology, and in particular to a rotor assembly mechanism. Background Technology

[0002] Before the rotor of the motor is assembled with the stator, a bushing, rubber gasket and graphite shim need to be installed on it. The bushing has a front and a back. Manual assembly is not only prone to errors, affecting subsequent assembly work, but also has low efficiency. Summary of the Invention

[0003] This invention solves the problems in related technologies and proposes a rotor assembly mechanism. Through the cooperation of the rotor feeding assembly, shaft sleeve assembly assembly assembly, washer assembly assembly assembly, and gasket assembly assembly assembly, the automatic assembly of shaft sleeves, washers, and gaskets can be realized, improving assembly efficiency. Moreover, it can detect the positive and negative orientation of the shaft sleeve, improving assembly accuracy and preventing subsequent reversed shaft sleeve assembly, which would affect motor performance.

The bushing flipping assembly mechanism is located on one side of the bushing front and back detection mechanism and is used for flipping and assembling the bushing. A washer assembly assembly includes a washer feeding mechanism and a washer assembly transfer mechanism. The washer feeding mechanism feeds the washer to the washer assembly transfer mechanism, which then presses it onto the shaft of the rotor. A gasket assembly assembly includes a gasket feeding mechanism and a gasket assembly transfer mechanism, wherein the gasket feeding mechanism feeds gaskets to the gasket assembly transfer mechanism and the gasket assembly transfer mechanism presses them onto the shaft of the rotor; The unloading cylinder module is installed at the end of the base plate and is used for unloading the rotor assembly.

[0005] As a preferred embodiment, the system also includes a rotor waste removal assembly, which comprises a waste removal belt, a waste kicking cylinder module, and a detection camera. The waste kicking cylinder module is installed at the end of the base plate and transfers the defective rotor assembly detected by the detection camera to the waste removal belt.

[0006] As a preferred embodiment, the rotor feeding assembly includes a frame transfer assembly, a ground rail assembly, and a rotor feeding assembly. The frame transfer assembly includes a frame gripping assembly, a frame lifting assembly, and a frame translating assembly. Driven by the frame lifting assembly and the frame translating assembly, the frame gripping assembly grips the frame and transfers it to the frame unloading station. The ground rail assembly transports the frame carrying the rotor between the frame transfer assembly and the rotor feeding assembly. The rotor feeding assembly includes a rotor gripping assembly, a rotor lifting assembly, a rotor translating assembly, a rotor flat-push platform, and a rotor transfer assembly. Driven by the rotor lifting assembly and the rotor translating assembly, the rotor gripping assembly grips the rotor onto the rotor flat-push platform. The rotor flat-push platform pushes the rotor to the rotor transfer assembly for feeding.

[0007] As a preferred embodiment, the rotor flat pusher platform includes a pusher plate, an auxiliary pusher plate, and a pusher base plate. The pusher base plate is provided with a strip-shaped groove with an opening at one end, and the pusher base plate has a strip-shaped opening at the position corresponding to the strip-shaped groove.

It also allows for the detection of the correct orientation of the bushings, improving assembly accuracy and preventing subsequent reverse assembly of bushings that could affect motor performance. The present invention uses a material frame transfer assembly to transfer the material frame to the ground rail assembly, and uses a forklift to place the rotor on the material frame and the ground rail assembly to transport the material frame to the rotor feeding assembly for orderly feeding, thereby improving the feeding efficiency. The final assembly is inspected by a camera, and defective products are kicked out by the rotor waste removal component and conveyed by the waste removal belt. The material frame uses a magnetic gripping mechanism, which makes gripping more precise and the structure simpler. It also uses an anti-rotation guide rod to prevent the magnetic floating head assembly from rotating. The sliding seat of the ground rail assembly has positioning posts for positioning the material frame, ensuring that the material frame is accurately positioned on the conveying assembly; The rotor gripping uses a clamping plate, which can grip a row of rotors at once, increasing the number of grips and efficiency. The rotor gripping assembly can be finely positioned using a floating bracket, which can improve gripping accuracy; The stepped structure at the end of the movable sleeve, along with a detection rod and proximity switch, enables the detection of the sleeve's orientation, making the detection simple and quick and avoiding subsequent assembly errors.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0020] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0021] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

[0022] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0023] like Figures 1 to 20 As shown, a rotor assembly mechanism includes a rotor feeding assembly 1, a shaft assembly assembly 2, a washer assembly assembly 3, a gasket assembly assembly 4, and a discharge cylinder module 5.

[0024] Rotor feeding assembly 1 feeds rotor 6 to rotor gripping stepping assembly 7, specifically, as follows: Figure 5As shown, the rotor feeding assembly 1 includes a frame transfer assembly 11, a ground rail assembly 12, and a rotor feeding assembly 13. The frame transfer assembly 11 is used to transfer empty frames 14 from the rotor feeding assembly 13 to the frame unloading station. Specifically, the frame transfer assembly 11 includes a frame gripping assembly 111, a frame lifting assembly 112, and a frame translating assembly 113. The frame gripping assembly 111 descends under the drive of the frame lifting assembly 112 to grip the empty frames 14 and translates them to the frame unloading station via the frame translating assembly 113, stacking them layer by layer. The ground rail assembly 12 is installed at the bottom of the rotor feeding assembly 13 and transports the frames with rotors 6 between the frame transfer assembly 11 and the rotor feeding assembly 13. For example, when the rotors on the first layer of frames 14... After all 6 rotors are loaded, the ground rail assembly 12 transports the material frame 14 with rotor 6 to the vicinity of the material frame transfer assembly 11. The material frame transfer assembly 11 then transfers the empty material frame 14 to the material frame unloading station. Subsequently, the ground rail assembly 12 transports the material frame with rotor 6 back to the rotor feeding assembly 13 for continued loading. The rotor feeding assembly 13 includes a rotor gripping assembly 131, a rotor lifting assembly 132, a rotor translation assembly 133, a rotor flat pushing platform 134, and a rotor transfer assembly 135. The rotor gripping assembly 131 descends under the drive of the rotor lifting assembly 132 to grip the rotor 6 and translates it onto the rotor flat pushing platform 134 via the rotor translation assembly 133. The rotor flat pushing platform 134 then pushes the rotor 6 to the rotor transfer assembly 135 for loading.

[0025] In one embodiment, such as Figure 6-7 As shown, the material frame gripping assembly 111 includes a magnetic floating head assembly mounted on the first lifting plate 1121 via a connecting plate 1114. Each connecting plate 1114 has two magnetic floating head assemblies. Each magnetic floating head assembly includes a magnetic head buffer assembly (consisting of a guide rod and a compression spring sleeved on the guide rod) and four magnetic heads 1112 mounted on the mounting base 1111. The mounting base 1111 is mounted on the connecting plate 1114 via a buffer assembly 1113. The buffer assembly 1113 includes a guide rod and a compression spring sleeved on the guide rod. One end of the guide rod is connected to the mounting base 1111, and the other end is mounted on the connecting plate 1114 via a linear bearing. In addition, to prevent the magnetic floating head assembly from rotating, an anti-rotation guide rod 1115 is also installed between the connecting plate 1114 and the mounting base 1111.

[0026] The material frame translation assembly 113 includes a first translation plate 1131 and a translation cylinder 1132. The material frame lifting assembly 112 includes a lifting cylinder 1122 and a guide column mounted on the first translation plate 1131. The lifting cylinder 1122 drives the first lifting plate 1121 to rise and fall. The first translation plate 1131 is slidably mounted on a linear guide rail on the top of the first support frame 114 and slides along the linear guide rail under the drive of the translation cylinder 1132.

[0027] In one embodiment, such as Figure 8 As shown, the ground rail assembly 12 is located at the bottom of the rotor feeding assembly 13 and extends to the vicinity of the material frame transfer assembly 11. The ground rail assembly 12 includes a conveying cylinder 121 and a sliding seat 122. The conveying cylinder 121 drives the sliding seat 122 to slide on the linear guide rail, thereby realizing the conveying of the material frame 14. The linear guide rail is installed on the base frame 124. Positioning posts 123 for positioning and installing the material frame 14 are provided at the four corners of the sliding seat 122. The four posts of the material frame 14 are inserted into the positioning posts 123.

[0028] In one embodiment, such as Figure 9 As shown, the rotor gripping assembly 131 includes a clamping plate 1311 and a clamping cylinder 1312. The two clamping plates 1311 slide towards each other or away from each other along the linear guide under the drive of the clamping cylinder 1312, thereby enabling the clamping and releasing of the rotor 6. When the two clamping plates 1311 come close to each other, they can grip up a row of rotors 6.

[0029] In one embodiment, such as Figure 10 As shown, the rotor lifting assembly 132 includes a lifting drive device 1321 and a second lifting plate 1322. The rotor gripping assembly 131 is mounted on the second lifting plate 1322 via a floating bracket 1313. The second lifting plate 1322 can slide slightly along the floating bracket 1313 under the drive of the floating cylinder 1314. The floating bracket 1313 plays the role of fine-tuning the rotor gripping assembly 131, making the gripping more precise. The second lifting plate 1322 is driven to rise and fall by the lifting drive device 1321. The lifting drive device 1321 includes a lifting motor, a synchronous pulley set, and a lead screw pair. The lead screw pair is connected to the second lifting plate 1322. The lifting motor drives the lead screw pair through the synchronous pulley set, thereby driving the second lifting plate 1322 to rise and fall. The rotor translation assembly 133 includes a translation motor, a ball screw pair, and a second translation plate. The second translation plate is connected to a nut on the ball screw pair. The translation motor drives the ball screw to rotate, thereby driving the second translation plate to translate along the linear guide rail.

[0030] In addition, the first support frame 114 has an L-shaped structure and its horizontal end is connected to the second support frame 136. A material frame sensing bracket 1361 is also installed on the side of the second support frame 136 away from the first support frame 114. The material frame sensing bracket 1361 is equipped with a sensor at the position corresponding to each layer of rotor 6 to sense whether the material frame 14 and rotor 6 of each layer exist.

[0031] In one embodiment, such as Figure 11-12As shown, the rotor flat pusher platform 134 includes a pusher plate 1341, an auxiliary pusher plate 1342, and a pusher base plate 1343. The pusher base plate 1343 has a strip-shaped groove 1344 with an opening at one end, and a strip-shaped opening 1345 corresponding to the position of the strip-shaped groove 1344. Sensors are installed on both sides of the strip-shaped groove 1344. The pusher plate 1341 is mounted on a guide rod via a pusher plate slider. The piston rod of the pusher plate cylinder 1346 is connected to the pusher plate slider. The pusher plate 1341 is pushed by the pusher plate cylinder 1346 to slide within the strip-shaped opening 1345, thus pushing the rotor 6. Due to space limitations, the stroke of the cylinder cannot be met by the pusher plate cylinder 1346 alone; therefore, an auxiliary pusher cylinder 1342 is provided. 348 is used to compensate for the stroke. Specifically, the auxiliary push plate 1342 is mounted on the guide rod via the auxiliary push plate slider, and the auxiliary push plate 1342 is connected to the auxiliary push plate cylinder 1348. The auxiliary push plate 1342 slides under the drive of the auxiliary push plate cylinder 1348. In addition, the auxiliary push plate 1342 also extends or retracts from the strip opening 1345 under the push of the push plate lifting cylinder 1347. When the push plate 1341 pushes the rotor 6 to move, the auxiliary push plate 1342 is in the retracted state. When the push plate cylinder 1346 completes its stroke and the auxiliary push plate cylinder 1348 needs to work, the auxiliary push plate 1342 is in the extended state, and the auxiliary push plate cylinder 1348 continues to drive the auxiliary push plate 1342, thereby driving the rotor 6 to continue to move.

[0032] In one embodiment, the rotor transfer assembly 135 includes two vertically and slidably connected linear modules, with a suction head installed at the end of the vertical linear module to feed the rotor 6 to the rotor gripping stepping assembly 7.

[0033] During loading, rotor 6 is fed by a forklift or manually and placed on the material frame 14. The material frame 14, filled with rotor 6, is then transported by the ground rail assembly 12 to the rotor feeding assembly 13. The rotor lifting assembly 132 drives the rotor gripping assembly 131 to descend to rotor 6 and grip it. The rotor is then moved by the rotor translation assembly 133 to the rotor pushing platform 134. The rotor gripping assembly 131 releases rotor 6, and the rotor pushing platform 134 pushes rotor 6 to the rotor transfer assembly 135 for loading. Each layer of material frame... After the rotor 6 on 14 is loaded, the ground rail assembly 12 transports the material frame 14 containing the rotor 6 to one side of the material frame unloading station. The material frame lifting assembly 112 drives the material frame gripping assembly 111 to descend and grab the empty material frame 14. Then, the material frame lifting assembly 112 drives the material frame gripping assembly 111 to rise, and then the material frame translating assembly 113 translates it to the material frame unloading station. The material frame lifting assembly 112 drives the material frame gripping assembly 111 to descend, and the material frame gripping assembly 111 releases the material frame 14 and places the empty material frames 14 in sequence. Then, the material frame gripping assembly 111 returns to its original position.

[0034] like Figure 2 As shown, the rotor gripping stepping assembly 7 includes a rotor clamping mechanism 71 that slides left and right on the base plate 73 driven by a second linear drive mechanism 75. The rotor clamping mechanism 71 can also move closer to or further away from the corresponding assembly component under the drive of a first linear drive mechanism 72. Specifically, the rotor clamping mechanism 71 includes three rotor grippers 712 mounted on a gripper connecting plate 711. The first linear drive mechanism 72 includes a first cylinder and a first linear guide rail. The second linear drive mechanism 75 includes a second cylinder and a second linear guide rail. The gripper connecting plate 711 is slidably mounted on the first linear guide rail and slides back and forth along the first linear guide rail under the drive of the first cylinder. The rail is mounted on the inlet / outlet base plate 74, which is also slidably mounted on the second linear guide rail on the base plate 73 and slides left and right along the second linear guide rail under the drive of the second cylinder. That is, the rotor gripper 712 can move left and right to reach the corresponding shaft assembly station, washer assembly station and gasket assembly station. The rotor gripper 712 approaches the corresponding shaft assembly station, washer assembly station and gasket assembly station under the drive of the first linear drive mechanism 72, so as to assemble the shaft sleeve 61, washer 62 and gasket 63. The shaft assembly assembly component 2, washer assembly component 3, gasket assembly component 4 and unloading cylinder module 5 are sequentially mounted on the assembly base plate 76.

[0035] Among them, such as Figure 13 As shown, the bushing assembly 2 includes a bushing feeding mechanism 21, a bushing front and back detection mechanism 22, and a bushing flipping assembly mechanism 23. The bushing feeding mechanism 21 feeds the bushing 61 to the bushing front and back detection mechanism 22 for front and back detection. The bushing flipping assembly mechanism 23 is located on one side of the bushing front and back detection mechanism 22 and is used for flipping and assembling the bushing 61. When assembling the bushing 61, the front and back of the bushing 61 are first detected by the bushing front and back detection mechanism 22. If it is detected that it needs to be flipped, it is flipped by the bushing flipping assembly mechanism 23. At this time, the rotor 6 is clamped by the rotor clamping mechanism 71 and approaches the bushing assembly assembly 2 under the drive of the first linear drive mechanism 72. The bushing flipping assembly mechanism 23 assembles the bushing 61 onto the rotor 6. After the rotor 6 with the bushing 61 is assembled, it is driven by the second linear drive mechanism 75 to move to the washer assembly assembly 3 for the assembly of the washer 62. The empty rotor then moves to the bushing assembly assembly 2 to wait for the bushing 61 to be assembled.

[0036] In one embodiment, the bushing feeding mechanism 21 includes a vibratory feeder and a translation component. The vibratory feeder feeds the bushing 61 to the translation component and the translation component moves it. Here, the translation component can be implemented by a cylinder pushing the bushing translation plate. The bushing 61 is fed to the bushing translation plate by the vibratory feeder, and then the cylinder pushes the bushing translation plate to slide on the linear guide rail to achieve feeding.

[0037] In one embodiment, such as Figure 14-15 As shown, the bushing forward and reverse detection mechanism 22 includes a detection rod 221, a proximity switch 222, a positioning post 223, a movable sleeve 224, a pressure rod 225, a fixed sleeve 226, and a pressure rod driving device 227. The detection rod 221 is rotatably mounted on the fixed sleeve 226, and the fixed sleeve 226 is fitted over the movable sleeve 224. The proximity switch 222 is mounted on the sensing plate, and the sensing plate is fixedly mounted on the fixed sleeve 226. A return spring 228 is fitted on the positioning post 223. The movable sleeve 224 is fitted over the positioning post 223, and the end of the movable sleeve 224 is stepped. One end of the pressure rod 225 is connected to the movable sleeve 224. Under the drive of the pressure rod driving device 227, the movable sleeve 224 drives the pressure rod 225 to move through its reaction force, thereby driving the detection rod 221 to move. Specifically, the outer diameter of the narrower end of the movable sleeve 224 is smaller than the inner diameter of the stepped surface of the bushing 61 but larger than the inner diameter of the plane of the bushing 61. When the step of the bushing 61... When the sleeve is facing upwards, the stepped structure at the end of the movable sleeve 224 descends to the stepped surface of the bushing 61 and gets stuck there, preventing it from descending further. At this time, a force is applied to the left end of the detection rod 221, causing the right end of the detection rod 221 to move upwards to the vicinity of the proximity switch 222, which can detect the detection rod 221. When the plane of the bushing 61 is facing upwards, because the outer diameter of the narrower end of the movable sleeve 224 is greater than the inner diameter of the plane of the bushing 61, the movable sleeve 224 is lifted by the bushing 61, causing the left end of the detection rod 221 to lose its force. The right end of the detection rod 221 droops under the action of gravity (at this time, the length of the right end of the pivot in the detection rod 221 is greater than the length of the left end of the pivot), or the right end of the detection rod 221 can also droop under the action of the spring, making it impossible for the proximity switch 222 to detect the detection rod 221. The detection signal from the proximity switch 222 can be used to determine which side of the bushing 61 is facing upwards.

[0038] In one embodiment, such as Figure 16 As shown, the bushing flipping assembly mechanism 23 is slidably mounted on the bushing cylinder module 24. The bushing cylinder module 24 includes two vertically and slidably connected linear modules, which can realize lifting and horizontal movement. The bushing flipping assembly mechanism 23 includes a pneumatic gripper 231 and a rotary cylinder 232. The rotary cylinder 232 is mounted on the bushing cylinder module 24. When it is detected that the stepped surface of the bushing 61 is facing upward, it needs to be flipped. At this time, the rotary cylinder 232 works, flipping the bushing 61 180° and then transferring it to the rotor 6 for assembly through the bushing cylinder module 24. If it is detected that the stepped surface of the bushing 61 is facing downward, it does not need to be flipped. At this time, the rotary cylinder 232 does not work, and the pneumatic gripper 231 grabs it and transfers it to the rotor 6 through the bushing cylinder module 24, thereby putting the bushing 61 on the rotor 6.

[0039] In one embodiment, such as Figure 17-18As shown, the washer assembly assembly 3 includes a washer feeding mechanism 31 and a washer assembly transfer mechanism 32. The washer feeding mechanism 31 includes a washer vibratory feeder 311 and a washer translation assembly 312. The vibratory feeder feeds the washer 62 to the washer translation assembly 31, which then translates it. Here, the washer translation assembly 31 can be implemented by a cylinder pushing the washer translation plate. The washer 62 is fed onto the washer translation plate by the washer vibratory feeder 311, and then the cylinder pushes the washer translation plate to slide on the linear guide rail to achieve feeding. The transfer mechanism 32 includes a cylinder module and a washer transfer rod 321. The washer transfer rod 321 is mounted on the cylinder module via a washer push plate assembly 322. A spring is fitted on the washer transfer rod 321 and a linear bearing is installed. The cylinder module drives the washer transfer rod 321 to move in the vertical and horizontal directions. Under the drive of the cylinder module, the washer transfer rod 321 descends, causing the washer 62 to be fitted onto the washer transfer rod 321. The washer transfer rod 321 has a central hole that allows the shaft of the rotor 6 to be inserted, making it convenient to assemble the washer 62 onto the shaft of the rotor 6.

The gasket tilting seat 412 is located on one side of the gasket vibratory feeder 411 and tilts the inclined gasket 63 to a horizontal position. Specifically, the gasket tilting seat 412 includes a tilting cylinder and a tilting plate. The tilting plate has a spacer for accommodating the gasket 63. The groove of 3, the flip plate is hinged to the support plate and the flip plate is connected to the piston rod of the flip cylinder through the hinge joint; the gasket assembly and transfer mechanism 42 includes a cylinder module and a gasket suction head 421. The gasket suction head 421 is installed on the cylinder module through the suction head push plate assembly 422. Then, the gasket suction head 421 picks up the gasket 63 under the drive of the cylinder module. The gasket suction head 421 has a central hole that allows the shaft of the rotor 6 to be inserted, so as to facilitate the assembly of the gasket 63 onto the shaft of the rotor 6.

[0041] The unloading cylinder module 5 is installed at the end of the base plate 73 and is used for unloading the rotor assembly. Specifically, the unloading cylinder module 5 includes a vertically and slidably connected linear module, wherein a suction head is installed on the vertical linear module to facilitate the suction of the rotor assembly.

[0042] In addition, such as Figure 4As shown, in order to remove defective rotor assemblies, a rotor waste removal assembly 8 is also set at the end of the entire assembly line. The rotor waste removal assembly 8 includes a waste removal belt 81, a waste kicking cylinder module 82, and an inspection camera 83. The waste kicking cylinder module 82 includes a waste kicking suction head, a slidingly connected lifting linear module, and a translation linear module. The waste kicking suction head is installed on the lifting linear module and can be lifted and translated under the drive of the lifting linear module and the translation linear module. The waste kicking cylinder module 82 is installed at the end of the base plate 73 and transfers the defective rotor assemblies detected by the inspection camera 83 to the waste removal belt 81.
