Therefore, it cannot be understood as a limitation on the present invention.

[0028] The following combination Figure 1-Figure 5 The utility model is described in detail.

[0029] Example

[0030] A device for potting magnetic steel glue for motor rotors includes a shunt component 1, which is detachably connected to several arm components 2 arranged circumferentially along the shunt component 1. A glue injection component 3 connected to the shunt component 1 is installed on the arm component 2, and the glue injection component 3 can be adjusted along the length of the arm component 2.

[0031] The shunt component 1 transports the magnetic steel glue to multiple glue injection components 3, and the glue injection components 3 inject glue into multiple magnetic steel slots at the same time. The glue injection components 3 can adjust their positions according to different models of motor rotors, thereby being suitable for multiple models of motor rotors.

[0032] The arm assembly 2 includes a connecting rod 21 connected to the diverter assembly 1. A slot 23 is defined along the length of the connecting rod 21. A slider 25 slides within the slot 23. The slider 25 is connected to a needle clamp 26 for holding the glue injection assembly 3. The slider 25, in conjunction with the slot 23, allows the glue injection assembly 3 to be adjusted along the length of the connecting rod 21. The arm assembly 2 can also be configured as a telescopic rod to adjust the position of the glue injection assembly 3.

[0033] The chute 23 is a through slot connecting both sides of the connecting rod 21. A first quick-tightening bolt 24 is threadedly connected to the side of the slider 25 away from the injection needle clamp 26, which is used to tighten against the connecting rod 21 to limit the movement of the slider 25. When tightened, the first quick-tightening bolt 24 presses the slider 25 against the chute 23, thereby limiting its movement and ensuring that the injection assembly 3 remains stationary after adjustment.

[0034] The flow diverter assembly 1 includes a diverter head 11, to which a curved mounting block 12 is connected. A connecting rod 21 is provided with a slot 22 at one end that mates with the curved mounting block 12. A second quick-tightening bolt 27 is threadedly provided on the connecting rod 21, extending through the slot 22 and abutting against the curved mounting block 12 to secure the connecting rod 21. After the connecting rod 21 is inserted into the curved mounting block 12 through the slot 22, the second quick-tightening bolt 27 secures the connecting rod 21. The connecting rod 21 can now be adjusted along the circumference of the curved mounting block 12. A different number of connecting rods 21 can be installed on the curved mounting block 12 according to usage requirements.

[0035] The cross section of the arc-shaped mounting block 12 and the slot 22 are both trapezoidal. After the arc-shaped mounting block 12 is inserted into the slot 22, the connecting rod 21 can rotate around the center of the arc-shaped mounting block 12, but the connecting rod 21 will not fall off the arc-shaped mounting block 12, thereby facilitating the installation of multiple connecting rods 21. Figure 5 As shown, the cross section of the arc-shaped mounting block 12 and the slot 22 may also be configured as a square structure to achieve the above technical effects.

[0036] The arc-shaped mounting block 12 can be set in the following manner: a notch for removing the connecting rod 21 can be machined from a section of annular mounting block; or at least two sections of arc-shaped mounting blocks 12 that can be spliced into a circular ring can be set, and the connecting rod 21 can be removed after removing one of the arc-shaped mounting blocks 12.

[0037] The diverter head 11 includes a diverter cover 112 with an opening at its lower end. A glue inlet pipe 111 is connected to the diverter cover 112. A cover plate 113 is detachably connected to the lower end of the diverter cover 112 via bolts 13. The cover plate 113 is provided with several hollow connectors 114 that communicate with the diverter cover 112. Magnetic steel glue is delivered from the glue inlet pipe 111 into the diverter cover 112, where it is then delivered to each glue injection assembly 3 via the hollow connectors 114. The cover plate 113 is detachably connected to the diverter cover 112, facilitating replacement of different cover plates 113. Different cover plates 113 have different numbers of hollow connectors 114 to accommodate the required number of glue injection assemblies 3.

[0038] The arc-shaped mounting block 12 is mounted on the bottom of the cover plate 113 via bolts 13, with the heads of the bolts 13 not protruding from the bottom surface of the arc-shaped mounting block 12. The arc-shaped mounting block 12 is also connected via bolts 13, facilitating assembly and disassembly of the flow diverter assembly 1. Furthermore, the heads of the bolts 13 not protruding from the bottom surface of the arc-shaped mounting block 12 prevent the bolts 13 from obstructing the connection rod 21 from adjusting its position on the arc-shaped mounting block 12.

[0039] The injection needle clamp 26 is made of elastic material, and can stably clamp the glue injection component 3 after being deformed.

[0040] The glue injection assembly 3 includes a needle 31 connected to a conduit 32. This conduit 32 plugs into the hollow connector 114 and delivers the magnetic steel glue to the vertically positioned needle 31 for injection. Conduit 32 is a flexible tube, allowing it to adjust its shape and maintain the flow of magnetic steel glue after the glue injection assembly 3 is adjusted. A rigid tube can also be used for this purpose, and custom-made rigid tubes can be customized to suit specific needs. However, this is more cumbersome, so a flexible tube is preferred.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
