Description

Technical fields:

[0001] This utility model belongs to the technical field of rotor assembly, and specifically refers to an automatic arrangement and feeding device for motor magnets. Background technology:

[0002] A type of motor rotor, such as Figure 1 As shown, the rotor body 4 includes an S-pole magnetic tile 41 and an N-pole magnetic tile 42. Several glue grooves 43 are provided on the outer peripheral wall of the rotor body 4. The glue grooves 43 are arranged circumferentially around the axis of the rotor body 4. The glue grooves 43 are respectively used for the S-pole magnetic tile 41 and the N-pole magnetic tile 42 to be inserted. The S-pole magnetic tile 41 and the N-pole magnetic tile 42 are arranged in a cross pattern. The S-pole magnetic tile 41 and the N-pole magnetic tile 42 are fixed to the rotor body 4 with glue. The rotor body 4 is provided with a positioning groove 44 to facilitate the positioning of the rotor body 4 during assembly.

[0003] During the assembly process of the motor rotor, after applying glue to the glue tank, the S-pole and N-pole magnetic tiles are manually attached to the rotor body. Manual attachment of magnetic tiles is prone to problems such as incorrect polarity positions and incorrect side-by-side assembly of tiles with the same polarity, which affects product quality. The assembly method needs to be improved. Summary of the Invention:

[0004] The purpose of this invention is to provide an automatic arrangement and feeding device for motor magnetic tiles to solve the technical problems mentioned in the background art.

[0005] This utility model is implemented as follows:

[0006] An automatic magnetic tile arrangement and feeding device for motors includes a base, an assembly seat that is lifted and slidably connected to the base, and a feeding rack on the base. The assembly seat is used to position the rotor body. The feeding rack has a plurality of feeding channels evenly distributed along the circumference. S-pole magnetic tiles and N-pole magnetic tiles are placed in the plurality of feeding channels respectively. The magnetic tiles placed in adjacent feeding channels are S-pole magnetic tiles and N-pole magnetic tiles respectively. A feeding port is opened at one end of the plurality of feeding channels that are close to each other. A drive cylinder is provided on the feeding rack. A plurality of pressure blocks are provided at the output end of the drive cylinder. A drive component is provided on the base for driving the assembly seat to move closer to the feeding port. The pressure blocks are used to press the magnetic tiles in the feeding port into the glue tank.

[0007] By adopting the above technical solution, in the actual assembly process, the rotor body is positioned on the assembly base, and the drive unit drives the assembly base to move closer to the feeding port, so that the glue groove on the rotor body is aligned with the feeding port. The drive cylinder drives the pressure block to move closer to the assembly base, so that the magnetic tiles in the glue groove of the feeding port are assembled. After the assembly is completed, the drive unit and the drive cylinder drive the assembly base and the pressure block to reset. After resetting, since the magnetic poles of the magnetic tiles in adjacent feeding channels are opposite, according to the principle of opposite poles attracting each other, the magnetic tiles in different feeding channels tend to move closer to each other under the action of magnetic force. Guided by the feeding channels, the magnetic tiles automatically enter the feeding port. If the magnetic poles of the magnetic tiles in adjacent channels are the same, the magnetic tiles tend to move away from each other and cannot enter the feeding port. This helps to reduce the occurrence of incorrect magnetic tile polarity arrangement after assembly, improves assembly speed and accuracy.

[0008] Preferably, the positions and quantities of the pressing blocks and the feeding ports are set to correspond to the glue tank.

[0009] By adopting the above technical solution, it is easy to assemble in one step, which helps to improve assembly efficiency.

[0010] Preferably, the feeding rack includes a feeding plate disposed on the base and a mounting column disposed on the feeding plate. The drive cylinder and the pressure block are disposed on the mounting column. The feeding channel and the feeding port are both opened on the feeding plate. The mounting column is provided with a plurality of limiting grooves. The limiting grooves are correspondingly arranged with the feeding channel and are connected to the corresponding feeding channel and the feeding port.

[0011] By adopting the above technical solution, the magnetic tiles that are close together are limited by the limiting groove and the feeding channel, which prevents the magnetic tiles that are close together from falling out of the feeding channel under the action of magnetism when there is little material left in the feeding channel.

[0012] Preferably, a pressure ring is provided outside the mounting post, and the pressure ring presses against the outer magnetic tile of the mounting post.

[0013] By adopting the above technical solution, the pressure ring is pressed onto the outer magnetic tile of the mounting column to prevent the magnetic tile from bulging upwards before entering the limiting groove.

[0014] Preferably, both the mounting post and the pressure ring are made of antimagnetic material.

[0015] By adopting the above technical solution, the mounting column and pressure ring are not easily magnetized, which helps to reduce the impact of external magnetic fields on the automatic feeding of magnetic tiles.

[0016] Preferably, the feed port accommodates only a single magnetic tile.

[0017] By adopting the above technical solution, it is not easy to pull out excess magnetic tiles during the process of the pressing block inserting the magnetic tile into the corresponding glue tank.

[0018] The outstanding advantages of this utility model compared to the prior art are:

[0019] 1. This utility model guides the magnetic tiles through the feeding channel, allowing them to automatically enter the feeding port. If the magnetic poles of the magnetic tiles in adjacent channels are the same, the magnetic tiles tend to move away from each other and cannot enter the feeding port. This helps to reduce the occurrence of incorrect magnetic tile polarity arrangement after assembly, improves assembly speed, and improves assembly accuracy.

[0020] 2. This utility model prevents the magnetic tile from bulging upwards before entering the limiting groove by pressing the pressure ring onto the outer magnetic tile of the mounting column;

[0021] 3. This utility model limits the magnetic tiles that are close together by using a limiting groove and a feeding channel to prevent the magnetic tiles from detaching from the feeding channel under the action of magnetism when there is little material left in the feeding channel.

[0027] The present invention will be further described below with reference to specific embodiments:

[0028] A motor rotor, see Figure 1The rotor body includes a rotor body 4, an S-pole magnetic tile 41, and an N-pole magnetic tile 42. Several glue grooves 43 are provided on the outer peripheral wall of the rotor body 4. The glue grooves 43 are arranged circumferentially around the axis of the rotor body 4. The glue grooves 43 are respectively used for the S-pole magnetic tile 41 and the N-pole magnetic tile 42 to be inserted. The S-pole magnetic tile 41 and the N-pole magnetic tile 42 are arranged in a cross pattern. The S-pole magnetic tile 41 and the N-pole magnetic tile 42 are fixed to the rotor body 4 with glue. The rotor body 4 is provided with a positioning groove 44 to facilitate the positioning of the rotor body 4 during assembly.

[0029] This application discloses an automatic arrangement and feeding device for motor magnetic tiles, see [link]. Figure 2 The assembly includes a base 1, an assembly seat 2, and a loading rack 3. The assembly seat 2 is vertically and slidably connected to the base 1, and is located above the base 1. A driving component 11, which is a lifting cylinder 111, is fixedly installed on the base 1. The lifting cylinder 111 is located below the base 1, and its housing is fixedly connected to the base 1. The piston rod of the lifting cylinder 111 is fixedly connected to the assembly seat 2, and the lifting cylinder 111 drives the assembly seat 2 to move up and down. The loading rack 3 is located on the side of the assembly seat 2 away from the base 1, and is fixedly connected to the base 1. The lifting cylinder 111 drives the assembly seat 2 to move closer to or away from the loading rack 3. In other embodiments, the driving component 11 can also be a linear motor.

[0030] See Figure 2 The feeding rack 3 has several feeding channels 311 at the end away from the assembly base 2. These feeding channels 311 are evenly spaced along the circumference and distributed around the outer perimeter of the assembly base 2. The distance between the feeding channels 311 gradually decreases as they approach the assembly base 2. The feeding channels 311 are for placing S-pole magnetic tiles 41 and N-pole magnetic tiles 42. The magnetic tiles placed in adjacent feeding channels 311 have different polarities. The opposite ends of the feeding channels 311, distributed horizontally, are attached to the magnetic tiles to guide them.

[0031] See Figure 2 and Figure 3 The position and number of the feeding channels 311 correspond one-to-one with the position and number of the glue tanks 43 of the rotor body 4. Several feeding channels 311 have feeding ports 312 at their ends that are close to each other. The feeding ports 312 pass through the feeding rack 3 along the direction close to the assembly seat 2. When the rotor body 4 to be processed is positioned on the assembly seat 2, the projections of the feeding ports 312 and the corresponding glue tanks 43 in the vertical direction coincide. The magnetic tiles in the feeding channels 311 enter the corresponding feeding ports 312 along the feeding channels 311 under the action of magnetism. The feeding ports 312 can only accommodate a single magnetic tile.

[0032] See Figure 3 and Figure 4The feeding rack 3 includes a feeding plate 31 and a mounting column 32. The feeding plate 31 is disc-shaped and fixedly connected to the base 1. The mounting column 32 is located on the side of the feeding plate 31 away from the base 1 and is fixedly connected to the feeding plate 31. The mounting column 32 is cylindrical, and its axis is on the same straight line as the center of the feeding plate 31. The radius of the mounting column 32 is smaller than the radius of the feeding plate 31. Feeding channels 311 and feeding ports 312 are formed on the feeding plate 31. Limiting grooves 321 are formed on the outer peripheral wall of the mounting column 32. The position and number of limiting grooves 321 correspond one-to-one with the position and number of feeding channels 311. The limiting grooves 321 are located above the corresponding feeding channels 311 and communicate with the corresponding limiting grooves 321 and feeding ports 312. The limiting grooves 321 allow the magnetic tiles to enter, and the inner walls of the limiting grooves 321, distributed horizontally, are in contact with the magnetic tiles.

[0033] The portion of the magnetic tiles that are close together on the feeding plate 31 protruding from the feeding channel 311 abuts against the inner wall of the limiting groove 321, reducing the possibility of magnetic tiles in adjacent feeding channels 311 detaching from the feeding channel 311 due to excessive attraction.

[0034] See Figure 3 and Figure 4 A drive cylinder 322 is installed inside the mounting column 32. Several pressure blocks 323 are connected to the output end of the drive cylinder 322. The drive rod 322 drives the pressure blocks 323 to move up and down and slide within the mounting column 32. The position and number of pressure blocks 323 correspond one-to-one with the position and number of feeding ports 312. The feeding ports 312 are located on the moving path of the pressure blocks 323. The pressure blocks 323 slide into or out of the feeding ports 312. The pressure blocks 323 are used to press the magnetic tiles in the feeding ports 312 into the corresponding glue tank 43. A connecting block 324 is fixed to the end of the pressure block 323 away from the feeding ports 312. The connecting block 324 is integrally formed with several pressure blocks 323. The piston rod of the drive cylinder 322 is connected through the connecting block 324. The drive cylinder 322 drives the pressure blocks 323 to move through the connecting block 324. The drive cylinder 322 is located on the side of the pressure blocks 323 away from the feeding ports 312.

[0035] A PLC controller is installed on the base 1 to control the movement of the drive cylinder 322 and the lifting cylinder 111. A start button is installed on the base 1 to output a start signal. After receiving the start program, the PLC controller controls the movement of the drive cylinder 322 and the lifting cylinder 111 according to the control program.

[0036] During the actual assembly process, the rotor body 4 is positioned on the assembly base 2, with the axis of the rotor body 4 and the axis of the loading plate 31 on the same straight line. When the start button is pressed, the PLC controller controls the lifting cylinder 111 to drive the assembly base 2 to move the rotor body 4 closer to the loading port 312 until the upper end of the rotor body 4 is in contact with the loading plate 31. The drive cylinder 322 drives the pressure block 323 to move downward to press the magnetic tile in the loading port 312 into the glue tank 43. The glue tank 43 is pre-coated with glue. The drive cylinder 322 and the lifting cylinder 111 drive the pressure block 323 and the assembly base 2 to reset respectively. The operator can then remove the assembled rotor from the assembly base 2.

[0037] See Figure 4 A pressure ring 325 is fitted onto the mounting post 32. Several pressure rings 325 are used to press down the outer magnetic tile of the mounting post 32, so that the magnetic tile is engaged in the feeding channel 311. The pressure ring 325 is slidably connected to the mounting post 32, and the magnetic tile supports the pressure ring 325. The height of the pressure ring 325 can be adapted to different magnetic tiles. In this embodiment, there is a gap between the upper end face of the magnetic tile located in the limiting groove 321 and the upper inner wall of the limiting groove 321.

[0038] Both the pressure ring 325 and the mounting post 32 are made of antimagnetic materials, making them less susceptible to magnetization by the magnetic tiles.

[0039] Before processing begins, S-pole magnetic tiles 41 and N-pole magnetic tiles 42 are placed into their respective feeding channels 311. Adjacent magnetic tiles have different polarities, and the innermost magnetic tiles move closer to each other under the influence of magnetism. The feeding channels 311 guide the magnetic tiles, allowing them to enter the corresponding feeding ports 312. Once the magnetic tiles in the feeding ports 312 are assembled, the magnetic tiles in the feeding channels 311 are continuously replenished to achieve automatic feeding.

[0040] In this embodiment, the number of magnetic tiles is 8.

[0041] The implementation principle of this application embodiment is as follows: When the start button 12 is pressed, the pressure block 323 simultaneously presses eight magnetic tiles into the corresponding glue tanks 43, resulting in high assembly efficiency. After assembly, the magnetic tiles in the feeding channel 311 automatically fill the feeding port 312, facilitating automatic feeding of the magnetic tiles. During the feeding process, if the magnetic tiles in adjacent channels have the same polarity, the magnetic tiles closest to the feeding port 312 in the feeding channel 311 tend to move away from each other and will not enter the feeding port 312, reducing the possibility of the rotor being unusable due to magnetic tile assembly errors. After the rotor body 4 is removed from the assembly base 2, the missing magnetic tiles can be assembled individually, which helps to reduce the scrap rate.

[0042] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
