Description

Technical Field

[0001] This invention relates to the field of rotor automated assembly technology, and in particular to an assembly device for a flat wire motor core and rotor shaft. Background Technology

[0002] In existing automated rotor assembly lines, it is usually necessary to heat the toroidal core first, and then insert the rotor shaft into the inner hole of the toroidal core. After the core and rotor shaft cool down, the next rotor assembly process is carried out.

[0003] For example, CN205051521U, "Low-Pressure Low-Temperature Interference Fit Assembly Machine for Cast Aluminum Rotors and Rotor Shafts," describes a heating device that includes a heating cylinder with an externally wound heating coil and two internal positioning rods. During assembly, the rotor is fed onto the two positioning rods, and the heating device heats the heating cylinder located within the heating cylinder on the two positioning rods. Then, a second drive device drives the positioning rods to contact the rotor, and a third drive device drives the first push rod to extend the rotor shaft into the rotor's inner hole and out of the inner hole until the rotor shaft reaches the bottom of the blind hole in the positioning rod.

[0004] However, there is currently no good automated assembly device for assembling the iron core and rotor shaft of flat wire motors that can achieve the heating of the iron core and rapid assembly of the rotor shaft in an automated rotor assembly production line. Summary of the Invention

The rotor shaft receiving plate is provided with a rotor shaft through slot for the rotor shaft to pass through.

[0013] Furthermore, the rotor shaft receiving plate is provided with a rotor shaft positioning groove.

[0014] Furthermore, the core heating mechanism includes a core temperature measuring component.

[0015] Furthermore, it includes a cold iron core transfer mechanism that transports the cold annular iron core to the iron core heating mechanism.

[0016] Furthermore, it includes a first hot-pressing transfer mechanism, and the cold iron core transfer mechanism can travel back and forth between the first hot-pressing transfer mechanism and the iron core heating mechanism.

[0017] Furthermore, the cold iron core transfer mechanism includes a cold iron core transfer slide rail, a cold iron core transfer platform that slides on the cold iron core transfer slide rail, and a cold iron core transfer drive assembly that drives the cold iron core transfer platform to move.

[0018] Furthermore, the cold iron core transfer platform is provided with a temperature measuring through hole, and the iron core temperature measuring component is located below the iron core heating coil assembly.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging the right heating core clamping part of the heating core transfer mechanism closer to the rotor shaft hot pressing mechanism and the left heating core clamping part closer to the core heating mechanism, and by configuring the right heating core clamping part to be rotatable along a fixed axis, when the heating core transfer mechanism returns from the rotor shaft hot pressing mechanism to the rotor shaft hot pressing mechanism, the right heating core clamping part rotates to avoid the core located in the rotor shaft hot pressing mechanism. This eliminates the need to wait for the core and rotor shaft to be assembled before the heating core transfer mechanism returns to the rotor shaft hot pressing mechanism, effectively improving the assembly efficiency of the core and rotor shaft.

Detailed Implementation

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

They are used only for the convenience of describing the invention and for simplifying the description, and 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1 and Figure 2 As shown, this invention provides an assembly device for the core and rotor shaft of a flat wire motor, mainly used in automated assembly lines for flat wire motor rotors. Figure 3 As shown, this device is specifically used after the first annular end cap, the annular iron core, and the second annular end cap are stacked on the rotor core clamping fixture. Specifically, after the first annular end cap, the annular iron core, and the second annular end cap are stacked on the iron core clamping platform 202, the annular iron core is heated, and the rotor shaft is pressed into the heated annular iron core for assembly. Specifically, the rotor core clamping fixture uses an L-shaped iron core clamping arm mechanism 203 to clamp the annular iron core and other components. The principle is that when the rotor core clamping fixture is powered on and energized, the core clamping arm mechanism 203 can be driven by a motor to rotate to a position facing the annular core, and the core clamping arm mechanism 203 can be driven by a cylinder to press the annular core and other components onto the core clamping platform 202; when the rotor core clamping fixture is de-energized, the cylinder is equipped with a locking valve, so it can still press the annular core and other components.

[0048] like Figures 4-6As shown, the flat wire motor core and rotor shaft assembly device of the present invention includes a core heating mechanism 301, a rotor shaft hot pressing mechanism 302, and a heated core transfer mechanism 303 that travels between the core heating mechanism 301 and the rotor shaft hot pressing mechanism 302. The core heating mechanism 301 includes a core heating coil assembly 301a, and the rotor shaft hot pressing mechanism 302 includes a rotor shaft hot pressing assembly 302a. The heated core transfer mechanism 303 includes a heated core transfer slide rail 303a arranged along the Y-axis, a heated core transfer platform 303b located on the heated core transfer slide rail 303a, and a heated core transfer drive device 303c that drives the heated core transfer platform 303b to move on the heated core transfer slide rail 303a. The heated core transfer platform 303b is provided with a heated core transfer connecting plate 303d arranged along the Z-axis. A left heated core clamping part 303e and a right heated core clamping part 303f are connected to the heating core transfer connecting plate 303d. The clamping arm of the left heated core clamping part 303e is arranged along the X-axis, and the left heated core clamping part 303e is located closer to the heated core mechanism 301. The right heated core clamping part 303f is located closer to the rotor shaft hot pressing mechanism 302. The right heating core clamping part 303f can rotate along a fixed axis. In this embodiment, the right heating core clamping part 303f rotates along the Z-axis under the action of a gear and rack mechanism. The left heating core clamping part 303e and the right heating core clamping part 303f can move closer to each other or further away from each other to clamp the annular core. In this embodiment, the right heating core clamping part 303f is configured as a structure that can only rotate and not move. The left heating core clamping part 303e can move along the Y-axis through a slide rail mechanism, that is, the left heating core clamping part 303e can move toward or away from the right heating core clamping part 303f.In the specific implementation process, the heated iron core transfer mechanism 303 moves into the iron core heating mechanism 301, and the right heated iron core clamping part 303f rotates to be parallel to the left heated iron core clamping part 303e; after the annular iron core is heated in the iron core heating mechanism 301, the left heated iron core clamping part 303e moves toward the right heated iron core clamping part 303f to clamp the heated annular iron core; then, under the action of the heated iron core transfer drive device 303c, the heated annular iron core moves to the rotor shaft hot pressing mechanism 30. After step 2, the left heating core clamping part 303e returns to its original position. Simultaneously, the right heating core clamping part 303f rotates to avoid the annular core located in the rotor shaft hot pressing mechanism 302, until its clamping arm faces the Y-axis. The heating core transfer mechanism 303 then returns to the core heating mechanism 301. During the return of the heating core transfer mechanism 303, the rotor shaft hot pressing mechanism 302 performs the process of hot pressing the rotor shaft to the annular core. The flat wire motor core and rotor shaft assembly device of the present invention, by setting the right heating core clamping part of the heating core transfer mechanism close to the rotor shaft hot pressing mechanism and the left heating core clamping part close to the core heating mechanism, and setting the right heating core clamping part to be rotatable along a fixed axis. When the heated iron core transfer mechanism returns from the rotor shaft hot pressing mechanism to the rotor shaft hot pressing mechanism, the right heated iron core clamping part rotates to avoid the iron core located in the rotor shaft hot pressing mechanism. Thus, the heated iron core transfer mechanism does not need to wait for the iron core and rotor shaft to be assembled before returning to the rotor shaft hot pressing mechanism, which effectively improves the assembly efficiency of the iron core and rotor shaft.

[0049] In this embodiment, as Figure 3 , Figure 7 , Figure 8 As shown, the right heating core clamping part 303f is provided with a first core positioning and transfer block 303g, and the left heating core clamping part 303e is provided with a second core positioning and transfer block 303h. The first core positioning and transfer block 303g and the second core positioning and transfer block 303h are arranged facing each other. Specifically, when the heating core transfer mechanism 303 needs to clamp the heated annular core, the first core positioning and transfer block 303g and the second core positioning and transfer block 303h cooperate with the first tooling positioning and transfer block 206 located on the core tooling base plate 201, so that the heating core transfer mechanism 303 can stably clamp the annular core located on the core tooling base plate 201. The present invention, through the setting of the first core positioning and transfer block and the second core positioning and transfer block, facilitates the heating core transfer mechanism to clamp and transfer the annular core more stably.

[0050] In this embodiment, as Figures 9-11As shown, under the action of the core heating coil driving device, the coil group of the core heating coil assembly 301a can move up and down along the height direction. Specifically, the core heating coil assembly 301a includes an inner core heating coil 301aa for heating the inner ring of the annular core and an outer core heating coil 301ab for heating the outer ring of the annular core. When heating the annular core, firstly, the core clamping arm mechanism 203 releases the pressure on the annular core, and the clamping arm of the core clamping arm mechanism 203 rotates and moves away, so that the core heating coil assembly 301 can cover the annular core. Immediately afterwards, the inner core heating coil 301aa extends downward into the inner ring of the annular core, and the outer core heating coil 301ab covers the outer ring of the annular core. The inner and outer rings of the annular core are heated together under the action of the core heating coil assembly 301a. This invention improves the heating effect of the annular iron core by setting up an inner iron core heating coil and an outer iron core heating coil.

[0051] In this embodiment, as Figures 12-13 As shown, a rotor shaft feeding mechanism 304 is also provided on one side of the rotor shaft hot pressing mechanism 302. The rotor shaft feeding mechanism 304 includes a rotor shaft gripping robot 304a, which may be a three-axis robot. The rotor shaft hot pressing mechanism 302 includes a rotor shaft receiving component 302b, which can move along the height direction. The rotor shaft receiving component 302b can reciprocate between the rotor shaft hot pressing component 302a and the rotor shaft feeding mechanism 304. The rotor shaft receiving component 302b can receive the rotor in the rotor shaft gripping robot 304a, and the rotor shaft receiving component 302b can move the rotor shaft to below the rotor shaft hot pressing component 302a.

[0052] Specifically, such as Figures 12-15As shown, the rotor shaft hot pressing mechanism 302 includes a rotor shaft hot pressing frame 302c, a rotor shaft hot pressing frame plate 302d on the rotor shaft hot pressing frame 302c, and a rotor shaft receiving assembly 302b including a rotor shaft receiving plate 302ba disposed below the rotor shaft hot pressing frame plate 302d and a rotor shaft receiving first driving assembly 302bb fixed on the rotor shaft hot pressing frame plate 302ba and driving the rotor shaft receiving plate 302ba to move along the height direction. The rotor shaft receiving first driving assembly 302bb can be a lead screw structure or a cylinder structure. The rotor shaft receiving plate 302ba is provided with a rotor shaft positioning groove 302bc. A rotor shaft receiving module for transferring the rotor shaft is provided between the rotor shaft receiving plate 302ba and the rotor shaft hot press frame plate 302d. A second drive assembly 302bd for receiving the rotor shaft is fixed on the rotor shaft receiving plate 302ba. The second drive assembly 302bd drives the rotor shaft receiving module to reciprocate between the rotor shaft hot press assembly 302a and the rotor shaft feeding mechanism 304. The rotor shaft receiving plate 302ba has a through slot for the rotor shaft to pass through. The rotor shaft receiving module for transferring the rotor shaft can be a clamping arm for holding the rotor shaft, or it can be a clamping plate with a clamping part. The second drive assembly 302bd can be a lead screw structure.

[0053] In this embodiment, a rotor shaft lifting mechanism 304b is also provided below the rotor shaft gripping robot 304a. When loading the rotor shaft, the rotor shaft is placed on the rotor shaft loading plate 304c, which is placed on the rotor shaft loading trolley 304d. The rotor shaft loading trolley 304d, containing the rotor shaft, is manually pushed into the rotor shaft loading mechanism 304. The rotor shaft lifting mechanism 304b can lift the rotor shaft loading plate 304c together with the rotor shaft, and the rotor shaft gripping robot 304a grips the rotor shaft. Simultaneously, the rotor shaft receiving module descends under the action of the first rotor shaft receiving drive component 302bb, and moves towards the rotor shaft loading mechanism 304 under the action of the second rotor shaft receiving drive component 302bd until it reaches the rotor shaft receiving position, at which point the rotor shaft receiving module stops moving. After the rotor shaft gripping robot 304a transfers the rotor shaft to above the rotor shaft receiving module, it is driven to descend and pass the rotor shaft through the rotor shaft through slot, simultaneously positioning the rotor shaft in the rotor shaft positioning slot 302bc. Then, the rotor shaft receiving module receives the rotor shaft, and the rotor shaft gripping robot 304a releases the rotor shaft. Subsequently, under the action of the first drive assembly 302bb and the second drive assembly 302bd, the position of the rotor shaft receiving module is adjusted until the rotor shaft is positioned below the pressure head of the rotor shaft hot pressing assembly 302a. This invention, through the rotor shaft feeding mechanism and the rotor shaft receiving assembly, facilitates the automatic feeding of rotor shafts.

[0054] like Figure 2 , Figure 6 and Figure 16As shown, the present invention includes a cold iron core transfer mechanism 305 for transporting a cold annular iron core to the iron core heating mechanism 301. The cold iron core transfer mechanism 305 includes a cold iron core transfer slide rail 305a, a cold iron core transfer platform 305b sliding on the cold iron core transfer slide rail 305a, and a cold iron core transfer drive assembly 305c for driving the movement of the cold iron core transfer platform 305b. The cold iron core transfer slide rail 305a is arranged along the X-axis direction. The heated iron core transfer mechanism 303 can remove the rotor iron core clamping fixture from the cold iron core transfer mechanism 305. It also includes a first hot-pressing transfer mechanism 306, and the cold iron core transfer mechanism 305 can travel back and forth between the first hot-pressing transfer mechanism 306 and the iron core heating mechanism 301. The first hot-pressing transfer mechanism 306 is provided with a cooling iron core transfer robot 306a that transfers the cold annular iron core from the external device to the cooling iron core transfer mechanism 305. The cooling iron core transfer robot 306a can be a three-axis robot. In the flat wire motor rotor assembly line, after the first annular end cap, the annular core, and the second annular end cap are stacked on the rotor core clamping fixture, the cooling core transfer robot 306a grabs the rotor core clamping fixture from an external device. Simultaneously, the cold core transfer platform 305b moves close to the first hot-pressing transfer mechanism 306, and the cooling core transfer robot 306a places the rotor core clamping fixture carrying the annular core onto the cold core transfer platform 305b. Then, the cooling core transfer mechanism 305 transports the rotor core clamping fixture carrying the annular core to the core heating mechanism 301. This invention, through the setting of the cold core transfer mechanism and the first hot-pressing transfer mechanism, achieves automatic transportation of the annular core to the core heating mechanism.

[0055] like Figure 4 As shown, the core heating mechanism 301 includes a core temperature measuring component 301b. A temperature measuring through-hole is provided on the cold core transfer platform 305b. The core temperature measuring component 301b is located below the core heating coil assembly 301a, and can extend and pass through the temperature measuring through-hole. When the cooling core transfer mechanism 305 transports the rotor core clamping fixture carrying the annular core to below the core heating coil assembly 301a, the core heating coil assembly 301a descends. Simultaneously, the core temperature measuring component 301b extends and passes through the temperature measuring through-hole to measure the temperature of the annular core. This invention, through the arrangement of the core temperature measuring component and the temperature measuring through-hole, facilitates the monitoring of the heating status of the annular core.

[0056] like Figure 2 , Figure 6 and Figure 17As shown, the present invention includes a hot-pressed rotor transfer mechanism 307 for transporting a rotor after hot-pressing the rotor shaft assembly away from the hot-pressing mechanism 302. The hot-pressed rotor transfer mechanism 307 includes a hot-pressed rotor transfer slide rail 307a, a hot-pressed rotor transfer platform 307b sliding on the hot-pressed rotor transfer slide rail 307a, and a hot-pressed rotor transfer drive assembly 307c for driving the hot-pressed rotor transfer platform 307b. The hot-pressed rotor transfer slide rail 307a is also arranged along the X-axis direction. The heated iron core transfer mechanism 303 can place a clamping fixture carrying an annular iron core onto the hot-pressed rotor transfer mechanism 307. The system also includes a second hot-pressing transfer mechanism 308. The hot-pressing rotor transfer mechanism 307 can travel back and forth between the second hot-pressing transfer mechanism 308 and the rotor shaft hot-pressing mechanism 302. The second hot-pressing transfer mechanism 308 is equipped with a hot-pressing rotor transfer robot 308a that transfers the rotor, after the rotor shaft hot-pressing assembly is completed, from the hot-pressing rotor transfer mechanism 307 to an external device. The cooling core transfer robot 308a can also be a three-axis robot. In the flat wire motor rotor assembly line, after the rotor shaft is hot-pressed into the annular core, the hot-pressing rotor transfer mechanism 307 carries the hot-pressed rotor from the rotor shaft hot-pressing mechanism 302 to the second hot-pressing transfer mechanism 308. The cooling core transfer robot 308a picks up the rotor and transfers it to the next device in the flat wire motor rotor production line. This invention achieves automatic rotor transfer after the hot-pressing process is completed by setting up the hot-pressing rotor transfer mechanism and the second hot-pressing transfer mechanism.

[0057] like Figure 6 and Figure 13 As shown, the rotor shaft hot pressing mechanism 302 includes a hot pressing dummy shaft assembly 302e. The hot pressing rotor transfer platform 307b is provided with a hot pressing dummy shaft through hole. The hot pressing dummy shaft assembly 302e is located below the rotor shaft hot pressing assembly 302a, and can extend and pass through the hot pressing dummy shaft through hole. When the hot pressing rotor transfer mechanism 307b carries the heated annular iron core and is located below the rotor shaft hot pressing assembly 302a, and the rotor shaft is located between the heated annular iron core and the rotor shaft hot pressing assembly 302a, the rotor shaft hot pressing assembly 302a descends. Simultaneously, the hot pressing dummy shaft assembly 302e can extend and pass through the hot pressing dummy shaft through hole. This invention, through the setting of the hot pressing dummy shaft assembly and the hot pressing dummy shaft through hole, facilitates ensuring the coaxiality of the iron ring during rotor shaft hot pressing.

[0058] The main working steps of the flat wire motor core and rotor shaft assembly device of the present invention are as follows:

[0059] S1, after the first annular end cap, the annular iron core, and the second annular end cap are stacked on the rotor iron core clamping fixture, the gas and power of the rotor iron core clamping fixture are cut off, the cold iron core transfer platform 305b moves to the first hot pressing transfer mechanism 306, and the cooling iron core transfer robot 306a grabs the rotor iron core clamping fixture onto the cold iron core transfer platform 305b.

[0060] S2, under the drive of the cold iron core transfer drive assembly 305c, the cold iron core transfer platform 305b transports the rotor iron core clamping fixture to the iron core heating mechanism 301, specifically transporting the rotor iron core clamping fixture directly below the iron core heating coil assembly 301a.

[0061] S3, the rotor core clamping fixture is ventilated and energized, the core clamping arm mechanism 203 releases the pressure on the annular core and other components, and rotates in a direction away from the annular core.

[0062] S4, the iron core heating coil assembly 301a descends and heats the annular iron core; at the same time, the iron core temperature measuring assembly 301b rises and monitors the temperature of the annular iron core.

[0063] S5, after the annular iron core heating is completed, the rotor iron core clamping fixture is ventilated and energized. After the iron core clamping arm mechanism 203 presses the annular iron core and other components again, the rotor iron core clamping fixture is de-energized and energized. At the same time, the heated iron core transfer mechanism 303 is located in the iron core heating mechanism 301, and the clamping arm of the right heated iron core clamping part 303f rotates to face the Y-axis direction.

[0064] S6, the left heating core clamping part 303e moves toward the right heating core clamping part 303f to clamp the rotor core clamping fixture and transfer the rotor core clamping fixture to the rotor shaft hot pressing mechanism 302; at the same time, the hot pressing rotor transfer platform 307b is located in the rotor shaft hot pressing mechanism 302.

[0065] S7, the clamping arm of the right heating core clamping part 303f rotates until it is turned toward the Y-axis direction, and the left heating core clamping part 303e moves away from the right heating core clamping part 303f, placing the rotor core clamping fixture carrying the annular core and other components onto the hot press rotor transfer platform 307b.

[0066] S8, the cold iron core transfer platform 305b moves toward the first hot-pressing transfer mechanism 306, and the heated iron core transfer mechanism 303 moves toward the iron core heating mechanism 301; simultaneously, when the rotor shaft loading trolley 304d is pushed into the rotor shaft loading mechanism 304, the rotor shaft lifting mechanism 304b lifts the rotor shaft, the rotor shaft gripping robot 304a grips the rotor shaft and transports it toward the rotor shaft hot-pressing mechanism 302; the rotor shaft receiving module moves downward under the action of the rotor shaft receiving first driving component 302bb, and the rotor shaft receiving module moves toward the rotor shaft loading mechanism 304 under the rotor shaft receiving second driving component 302bd; finally, the rotor shaft gripping robot 304a transfers the rotor shaft into the rotor shaft receiving module.

[0067] S9, the first drive assembly 302bb and the second drive assembly 302bd move the rotor shaft between the rotor shaft hot pressing assembly 302a and the annular iron core and other components; at the same time, the rotor iron core clamping fixture is ventilated and energized, and the iron core clamping arm mechanism 203 releases the pressure on the annular iron core and other components and rotates in a direction away from the annular iron core.

[0068] S10, the rotor shaft hot pressing assembly 302a descends, and at the same time, the hot pressing dummy shaft assembly 302e extends, and the rotor shaft hot pressing assembly 302a presses the rotor shaft into components such as the annular iron core.

[0069] S11, the hot-pressed rotor transfer platform 307b transports the rotor, after the rotor shaft and iron core have been assembled, to the second hot-pressed transfer mechanism 308.

[0070] S12, the hot-pressed rotor transfer robot 308a grabs the rotor shaft and iron core after they are assembled, and transfers it to the device for the next assembly process of the flat wire motor rotor automated production line.

[0071] In summary, the flat wire motor core and rotor shaft assembly device of the present invention, by arranging the right heating core clamping part of the heating core transfer mechanism near the rotor shaft hot pressing mechanism and the left heating core clamping part near the core heating mechanism, and by configuring the right heating core clamping part to be rotatable along a fixed axis, allows the heating core transfer mechanism to rotate when returning from the rotor shaft hot pressing mechanism to the rotor shaft hot pressing mechanism. This avoids the core located in the rotor shaft hot pressing mechanism, thus eliminating the need to wait for the core and rotor shaft to be assembled before the heating core transfer mechanism returns to the rotor shaft hot pressing mechanism, effectively improving the assembly efficiency of the core and rotor shaft. The arrangement of the first and second core positioning transfer blocks facilitates more stable clamping and transfer of the annular core by the heating core transfer mechanism. The arrangement of the inner and outer core heating coils enhances the heating effect of the annular core. The arrangement of the rotor shaft feeding mechanism and the rotor shaft receiving assembly facilitates automatic feeding of the rotor shaft. The ring-shaped iron core is automatically transported to the iron core heating mechanism via a cold iron core transfer mechanism and a first hot-pressing transfer mechanism. The iron core temperature measuring component and the temperature measuring through-hole facilitate monitoring of the ring-shaped iron core's heating status. The hot-pressing rotor transfer mechanism and the second hot-pressing transfer mechanism enable the automatic rotation out of the rotor after the hot-pressing process. The hot-pressing dummy shaft component and the hot-pressing dummy shaft through-hole ensure the coaxiality of the iron rings during rotor shaft hot pressing.

[0072] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
