Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and in particular to an automatic feeding device for assembling motor rotor retaining springs. Background Art

[0002] When assembling a motor, bearings need to be installed on the rotor so that the rotor can rotate smoothly relative to the stator, thereby achieving normal operation of the motor. When installing the bearings, it is usually necessary to install a retaining ring on the end shaft of the rotor to limit the bearing axially and assist in installation.

[0003] Traditionally, rotor-mounted retaining springs are manually opened and clamped into the rotor's annular groove using tools. This manual assembly method is time-consuming and labor-intensive, making it difficult to apply to large-scale motor production. Furthermore, manual errors can easily affect the retaining spring's installation and lead to poor consistency in the installation of each rotor retaining spring.

[0004] Therefore, some existing rotor circlip installation devices have emerged, which allow the motor rotor to be fixed to a base and a cylinder to push the circlip vertically onto the rotor's end shaft to achieve the circlip installation. However, due to the small size and thickness of the circlip, automatic loading of the circlip is difficult, resulting in manual installation of the circlip to the position pushed by the cylinder. This is inefficient and poses installation risks. In addition, manual error can easily lead to positional deviation of the circlip after installation, thus affecting the subsequent assembly of the motor rotor bearing. Summary of the Invention

[0024] In order to make the contents of the present invention more clearly understood, the present invention is further described below based on specific embodiments in conjunction with the accompanying drawings.

[0025] It should be noted that the terms "center," "upper," "lower," "front," "back," "left," "right," "inner," and "outer" used herein to indicate positions or locations are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, "plurality" means two or more.

[0026] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0027] like Figures 1 to 2 As shown, an automatic feeding device for assembling motor rotor retaining springs can automatically feed retaining springs when the motor rotor is being assembled with retaining springs, thereby improving the assembly efficiency of the motor rotor. The feeding accuracy is high, which can improve the assembly accuracy of retaining springs and facilitate the fully automatic and precise installation of motor rotor retaining springs. The automatic feeding device for retaining springs of this embodiment includes a vibration plate 1, a feeding seat 2, and a guide mechanism 3 connecting the vibration plate 1 and the feeding seat 2. A large number of scattered retaining springs can be placed in the vibration plate 1. Under the regular vibration of the vibration plate 1, they are gradually straightened so as to enter the guide mechanism 3 at the correct angle position. Finally, under the action of the guide mechanism 3, they are automatically transferred to the feeding seat 2 for automatic feeding. No human intervention is required in the entire process, facilitating the fully automatic assembly of motor rotor retaining springs.

[0028] like Figures 1 to 3 As shown, the material guide mechanism 3 of this embodiment includes a material guide strip 31 and a material guide bracket 32 ​​that are spliced ​​together, wherein a material discharge port 11 is opened at the bottom of the vibration disk 1, and the material guide strip 31 is vertically connected to the material discharge port 11 position of the vibration disk 1, so that after the retaining spring is discharged from the vibration disk 1, it can fall along the material guide bracket 32 ​​under the action of gravity and eventually move into the material guide bracket 32, so that it can be loaded by the material guide bracket 32; in other embodiments, the material guide strip 31 can also be set to be inclined longitudinally, and the same technical effect can also be achieved. In addition, the disk surface of the vibration disk 1 of this embodiment is inclined toward the material discharge port 11 position, so that the retaining spring can quickly move to the material discharge port 11 position under the vibration of the vibration disk 1, thereby quickly entering the material guide strip 31 from the material discharge port 11 at the correct angle to realize the loading of the retaining spring.

[0029] like Figure 2 and Figure 3 As shown, the guide bracket 32 ​​of this embodiment is horizontally arranged, and its end is connected to the loading seat 2. When the retaining spring is loaded into the loading seat 2, the opening of the retaining spring can face downward, thereby facilitating its engagement with the motor rotor. Furthermore, a conveyor belt 33 is installed within the guide bracket 32 ​​of this embodiment. After the retaining spring drops from the guide bar 31 and enters the guide bracket 32, it is driven by the conveyor belt 33 along the horizontal guide bracket 32 ​​into the loading seat 2, achieving automatic loading of the retaining spring, which can effectively improve the loading efficiency and accuracy of the retaining spring.

[0030] Specifically, such as Figure 3As shown, the cross-section of the material guide bracket 32 ​​of this embodiment is a "mountain"-shaped structure, including a material guide portion 321 located in the middle and a transmission portion 322 located on both sides of the material guide portion 321. Among them, the material guide portion 321 of this embodiment has the same structure as the material guide bar 31, and both are adapted to the inner ring structure of the retaining spring, so that the retaining spring can remain stable under the action of the material guide bar 31 or the material guide portion 321 when loading, thereby facilitating the precise loading of the retaining spring.

[0031] In order to enable the retaining spring to move stably along the horizontal guide strip 31, two conveyor belts 33 are provided in this embodiment, and the two conveyor belts 33 are respectively arranged in the conveying parts 322 on both sides. At the same time, the surfaces of the two conveyor belts 33 are arranged toward the central guide part 321, so that after the retaining spring falls along the guide strip 31 into the guide bracket 32, the conveyor belts 33 on both sides can simultaneously drive both sides of the retaining spring so that the retaining spring can move stably and quickly along the guide part 321, thereby realizing accurate and fast loading of the retaining spring, which can effectively improve the assembly efficiency and assembly accuracy of the motor rotor retaining spring.

[0032] In addition, if and Figure 3 As shown, a plurality of conveying bars 331 are equidistantly provided on the surface of the conveyor belt 33 of this embodiment, and the conveying bars 331 are vertically arranged so that a conveying channel 332 adapted to the thickness of the retaining spring can be formed between adjacent conveying bars 331, so that when the retaining spring is conveyed in the material guide bracket 32, the two ends of a single retaining spring can be respectively embedded in the conveying channel 332, thereby further improving the conveying stability of the retaining spring.

[0033] like Figures 1 to 3 As shown, in order to rotate the conveyor belt 33 and thus convey and load the clips, a transmission shaft 323 is vertically provided at each end of the conveying portion 322 of this embodiment. The conveyor belt 33 is mounted on the transmission shaft 323, so that when the transmission shaft 323 rotates, it can drive the conveyor belt 33 to move, thereby transporting the clips. In addition, a drive assembly 5 is mounted on the material guide bracket 32 ​​of this embodiment, which is in transmission connection with the transmission shaft 323. The drive assembly 5 allows the transmission shaft 323 to rotate, thereby driving the conveyor belt 33 to move.

[0034] Specifically, the drive assembly 5 of this embodiment includes a drive motor 51 fixedly mounted at the bottom of the material guide bracket 32 ​​and a drive wheel 52 mounted on the output shaft of the drive motor 51. The drive wheel 52 is in transmission connection with the transmission shaft 323, so that when the drive motor 51 is started, it can drive the transmission shaft 323 to rotate, thereby realizing the movement of the conveyor belt 33. In addition, in this embodiment, the transmission shaft 323 on the side away from the loading base 2 extends through the material guide bracket 32 ​​and is installed with a transmission gear 324. The transmission gears 324 of the two transmission shafts 323 are meshed with each other, so that when the drive wheel 52 is connected to any one of the transmission shafts 323 and drives them to rotate in unison, the other transmission shaft 323 can rotate under the action of the meshing of the transmission gears 324, thereby driving the two conveyor belts 33 to move in the same direction. This not only reduces the driving cost, but also allows the two conveyor belts 33 to move in the same direction, so that the two ends of the clip spring can move synchronously when the clip spring is used to convey and load the material, which can further improve the stability of the clip spring conveying and loading.

[0035] like Figure 1 、 Figure 2 and Figure 4 As shown, in order to enable the retaining spring to be automatically moved to the position of the motor shaft for clamping and assembly after being loaded into the loading seat 2, this embodiment provides a vertical feeding channel 21 on the side surface of the loading seat 2 away from the material guide bracket 32, and provides a feeding plug 4 on the top of the loading seat 2 to be inserted into the feeding channel 21. After the retaining spring is loaded into the feeding channel 21, the feeding plug 4 can move along the feeding channel 21 to push the retaining spring to the clamping position for clamping, thereby realizing fully automatic loading and clamping of the retaining spring.

[0036] In addition, in order to allow the retaining spring transmitted by the material guide bracket 32 ​​to enter the feeding channel 21, this embodiment provides a feeding channel 22 in the feeding seat 2, which horizontally passes through the side walls of the feeding seat 2 and is connected to the feeding channel 21. The end of the material guide bracket 32 ​​is inserted into the feeding channel 22, so that the retaining spring transmitted by the material guide bracket 32 ​​and the conveyor belt 33 enters the feeding seat 2, and can pass through the feeding channel 22 and enter the feeding channel 21, thereby moving along the feeding channel 21 under the push of the feeding plug block 4 to realize automatic loading.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, the feed plug 4 of this embodiment includes a mounting base 41 disposed on the top of the loading base 2 and a blade 42 vertically connected to the mounting base 41. The blade 42 is movably inserted into the feeding channel 21. The mounting base 41 can push the blade 42 along the feeding channel 21, thereby pushing the retaining spring loaded into the feeding channel 21 to move from the feeding channel 21 to the engaging position for engagement, thereby achieving automatic loading of the retaining spring. Furthermore, the surface of the blade 42 of this embodiment is in close contact with the inner wall of the feeding channel 21, which facilitates the blade 42 to push the retaining spring out of the feeding channel 21 to achieve loading.

[0038] In addition, the end of the insert blade 42 of this embodiment is provided with a snap-fit ​​interface 421, which can be snapped onto the end shaft of the motor rotor, thereby precisely feeding the retaining spring into the snap-fit ​​position for assembly. Furthermore, a bearing slot 422 is provided on the insert blade 42 of this embodiment, located near the sidewall of the feeding channel 22 and corresponding to the snap-fit ​​interface 421. When the insert blade 42 moves along the feeding channel 21 and the outlet of the feeding channel 22 coincides with the bearing slot 422, the retaining spring conveyed via the conveyor belt 33 can be ejected from the feeding channel 22 and enter the bearing slot 422, thereby being driven by the insert blade 42 to the snap-fit ​​position for loading. Furthermore, the structure of the bearing slot 422 of this embodiment is compatible with the outer shape of the retaining spring, allowing the retaining spring to enter the bearing slot 422 at the correct direction and angle during loading, thereby achieving precise loading of the retaining spring and facilitating subsequent precise assembly.

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, a buffer 6 is vertically mounted on the top of the loading base 2 of this embodiment, and the mounting base 41 abuts against the buffer 6. Therefore, the mounting base 41, driven by the clamping mechanism, drives the insert 42 along the feeding channel 21 to load the retaining spring. After that, the mounting base 41 automatically rebounds to its initial position driven by the buffer 6, thereby facilitating the subsequent loading of retaining springs. Furthermore, after the mounting base 41 rebounds, the bearing groove 422 of this embodiment can be precisely located at the output port of the feeding channel 22, thereby facilitating direct support of the retaining spring for feeding and assembly.

[0040] In summary, this embodiment sets up a material guiding mechanism 3 including a material guiding strip 31 and a material guiding bracket 32, and connects the material guiding strip 31 and the material guiding bracket 32 ​​to the vibration disk 1 and the loading seat 2 respectively, and installs a conveyor belt 33 in the material guiding bracket 32, so that the retaining spring can be automatically loaded into the material guiding strip 31 through the vibration disk 1, and fall into the material guiding bracket 32 ​​along the material guiding strip 31 under the action of gravity, and then automatically conveyed to the loading seat 2 through the conveyor belt 33 in the material guiding bracket 32 ​​to realize automatic and accurate loading of the retaining spring, which can improve the assembly efficiency and assembly accuracy of the retaining spring of the motor rotor, and facilitate the fully automatic installation of the retaining spring of the motor rotor.

[0041] In addition, by arranging a loading channel 22 and a feeding channel 21 that are interconnected on the loading seat 2, and arranging a feeding plug 4 in the feeding channel 21, the retaining spring transported by the guide mechanism 3 can enter the feeding channel 21 from the loading channel 22, and move along the feeding channel 21 to the clamping position under the push of the feeding plug 4, thereby realizing automatic loading of the retaining spring clamping and improving the assembly accuracy of the retaining spring.

[0042] The embodiments described above are only preferred implementations of the present invention and are not intended to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by those skilled in the art on the basis of the invention fall within the scope of protection of the present invention.
