Description

Technical Field

[0001] The 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 the 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 axially limit the bearing and assist in the installation.

[0003] Traditionally, the rotor mounting retaining spring is usually manually opened using tools and manually clamped into the annular groove of the rotor. This manual assembly method is time-consuming and labor-intensive, and is difficult to apply to the field of mass motor production. It is also easy for manual errors to affect the installation effect of the retaining spring, and result in poor consistency in the installation of each rotor retaining spring.

[0004] Therefore, some rotor retaining spring installation devices have appeared in the prior art, so that the motor rotor can be fixed on the base and the retaining spring is pushed by the cylinder to vertically clamp on the end shaft of the rotor to realize the installation of the retaining spring. However, due to the small size and thin thickness of the retaining spring, it is difficult to realize automatic feeding of the retaining spring, resulting in the need to manually install the retaining spring to the push position of the cylinder, which is inefficient and has installation risks.

Unless otherwise specified, "plurality" means two or more.

[0026] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] like Figure 1 to Figure 2 As shown, an automatic feeding device for assembling motor rotor retaining springs can automatically feed retaining springs when the motor rotor is assembling retaining springs, thereby improving the assembly efficiency of the motor rotor, and 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, and gradually straightened under the regular vibration of the vibration plate 1 so as to enter the guide mechanism 3 at the correct angle position, and finally automatically transferred to the feeding seat 2 under the action of the guide mechanism 3 to realize automatic feeding, and no manual participation is required in the whole process, which facilitates 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 ​​which are spliced ​​with each other, wherein a material discharge port 11 is provided at the bottom of the vibration disk 1, and the material guide strip 31 is vertically connected to the material discharge port 11 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 finally move into the material guide bracket 32, so that the retaining spring 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 obtained. In addition, the disk surface of the vibration disk 1 of this embodiment is inclined toward the material discharge port 11, so that the retaining spring can quickly move to the material discharge port 11 under the vibration of the vibration disk 1, so as to quickly enter the retaining spring from the material discharge port 11 to the material guide strip 31 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 the end is connected to the loading seat 2, so that when the clip is loaded into the loading seat 2, the opening of the clip can face downward so as to be easily connected to the motor rotor. Among them, a conveyor belt 33 is installed in the guide bracket 32 ​​of this embodiment, so that after the clip falling from the guide bar 31 enters the guide bracket 32, it can enter the loading seat 2 along the horizontal guide bracket 32 ​​under the drive of the conveyor belt 33, so as to realize automatic loading of the clip, which can effectively improve the loading efficiency and loading accuracy of the clip.

[0030] Specifically, Figure 3As shown, the cross-section of the material guide bracket 32 ​​of the present 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, wherein the material guide portion 321 of the present embodiment has the same structure as the material guide strip 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 strip 31 or the material guide portion 321 when being loaded, thereby facilitating the accurate loading of the retaining spring.

[0031] In order to ensure that the retaining spring can move stably along the horizontal guide strip 31, two conveyor belts 33 are provided in the present 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. Therefore, after the retaining spring falls into the guide bracket 32 ​​along the guide strip 31, the conveyor belts 33 on both sides can drive both sides of the retaining spring at the same time, 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 the present 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 to realize the conveying and loading of the clip, the transmission shafts 323 are vertically arranged at both ends of the conveying part 322 of this embodiment, and the conveyor belt 33 is sleeved on the transmission shaft 323, so that when the transmission shaft 323 rotates, the conveyor belt 33 can be driven to move, thereby realizing the transportation of the clip. In addition, the material guide bracket 32 ​​of this embodiment is also equipped with a driving component 5 that is transmission-connected to the transmission shaft 323, so that the transmission shaft 323 can rotate under the action of the driving component 5, thereby driving the conveyor belt 33 to move.

[0034] Specifically, the driving assembly 5 of this embodiment includes a driving motor 51 fixedly mounted at the bottom of the material guide bracket 32 ​​and a driving wheel 52 mounted on the output shaft of the driving motor 51. The driving wheel 52 is connected to the transmission shaft 323 in a transmission manner, so that when the driving motor 51 is started, the transmission shaft 323 can be driven to rotate, thereby realizing the movement of the conveyor belt 33. In addition, the bottom of the transmission shaft 323 of this embodiment, which is far away from the material loading seat 2, passes 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 driving wheel 52 is connected to any one of the transmission shafts 323 and driven to rotate together, the remaining transmission shafts 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, which not only reduces the driving cost, but also enables 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 transmit and load the material, which can further improve the stability of the clip spring transmission 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 which is inserted into the feeding channel 21 on the top of the loading seat 2, so that 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] Furthermore, in order to allow the retaining spring transmitted by the material guide bracket 32 ​​to enter the feeding channel 21, the present embodiment provides a feeding channel 22 in the feeding seat 2 which horizontally penetrates 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 then 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, Figure 2 and Figure 4 As shown, the feeding plug block 4 of this embodiment includes a mounting seat 41 disposed on the top of the feeding seat 2 and a plug knife 42 vertically connected to the mounting seat 41, wherein the plug knife 42 is movably plugged into the feeding channel 21, and the mounting seat 41 can push the plug knife 42 to move along the feeding channel 21, thereby pushing the clip loaded into the feeding channel 21 to move from the feeding channel 21 to the clamping position for clamping, thereby realizing automatic loading of the clip. In addition, the surface of the plug knife 42 of this embodiment is in close contact with the inner wall of the feeding channel 21, so that the plug knife 42 can push the clip in the feeding channel 21 out to realize loading.

[0038] In addition, the end of the insert knife 42 of this embodiment is provided with a card interface 421, and the card interface 421 can be connected to the end shaft of the motor rotor, so that the spring clip can be accurately fed to the card connection position for assembly. In addition, the insert knife 42 of this embodiment is close to the side wall of the feeding channel 22 and is provided with a bearing groove 422 at a position corresponding to the card interface 421, so that when the insert knife 42 moves along the feeding channel 21 and the outlet of the feeding channel 22 just corresponds to the position of the bearing groove 422, the spring clip transmitted via the conveyor belt 33 can be output from the feeding channel 22 and enter the bearing groove 422, so that it is driven by the insert knife 42 to the card connection position for loading. In addition, the structure of the bearing groove 422 of this embodiment is adapted to the outer shape structure of the spring clip, so that when the spring clip clip is loaded, it can enter the bearing groove 422 in the correct direction and angle, thereby realizing the accurate loading of the spring clip, which is convenient for subsequent accurate assembly.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, a buffer 6 is vertically mounted on the top of the loading seat 2 of this embodiment, and the mounting seat 41 is in contact with the buffer 6, so that the mounting seat 41 drives the inserting knife 42 to move along the feeding channel 21 to load the clip under the push of the clamping mechanism, and the mounting seat 41 can automatically rebound to the initial position driven by the buffer 6, so as to facilitate the subsequent loading of the clip. In addition, after the mounting seat 41 of this embodiment rebounds, the bearing groove 422 can be just located at the output port of the feeding channel 22, so as to facilitate the direct bearing of the clip for feeding and assembly.

[0040] In summary, this embodiment sets 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 material loading seat 2 respectively, and installs a conveyor belt 33 in the material guiding bracket 32 ​​at the same time, 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 material 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 block 4 in the feeding channel 21, the retaining spring transported by the material guiding 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 block 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 implementation modes of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and modifications made by those skilled in the art on the basis of the invention shall fall within the protection scope of the present invention.
