Description

Technical Field

[0001] The invention belongs to the technical field of motor processing equipment, and in particular relates to a motor rotor gluing device. Background Art

[0002] A motor rotor, such as Figure 1 The rotor body 81 includes a rotor body and a plurality of magnets 82 . The rotor body 81 is provided with a plurality of glue grooves 83 for the magnets 82 to be snapped into place.

[0003] During the assembly process of the motor rotor, in order to prevent the magnet from falling off when the rotor rotates, it is necessary to apply glue to the glue tank before the magnet is installed to increase the connection strength between the magnet and the rotor body. Traditional magnets are generally manually applied with glue to the glue tank, and then the magnet is clamped into the glue tank. In the related art, the gluing device applies glue to the glue head through a fixed gluing head. Applying glue to glue tanks of different sizes requires replacing gluing heads of different sizes. Although the adaptability of the gluing head can be improved by spraying, it is easy to spray glue out of the glue tank, resulting in glue waste, which needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a motor rotor gluing device to solve the technical problems raised in the above background technology.

[0005] The present invention is achieved in that:

[0006] A motor rotor gluing device comprises an operating table, a mounting base that is lifted and slidably connected to the operating table, and a plurality of glue injection parts arranged around the mounting base, wherein the mounting base is used to position the rotor body, and the glue injection part is provided with a glue coating head, which can restore its shape by its own elasticity after the external force is removed. The glue injection part drives the glue coating head to move closer to or away from the glue tank through a driving cylinder, and a glue storage cavity is provided on the glue coating head, and a glue application tank is provided at one end of the glue coating head close to the mounting seat, and a glue outlet is provided on the glue coating head, and the glue outlet is connected to the glue storage cavity and the glue application tank, and the end of the glue coating head close to the mounting seat protrudes in a circular arc shape in the direction close to the mounting seat.

[0007] By adopting the above technical solution, during the gluing process, the rotor body is mounted on the mounting seat, and the mounting seat moves to drive the rotor body between several gluing heads. The drive cylinder drives the glue injection unit to move the gluing head close to the corresponding glue tank, so that the upper glue tank is located within the glue tank. The glue in the glue storage chamber is squeezed into the upper glue tank from the glue outlet, and the glue overflowing from the upper glue tank is smeared on the inner wall of the glue tank. The gluing head has the ability to elastically deform, which is conducive to adapting to glue tanks of different sizes. The upper glue tank is located within the glue tank during gluing, which facilitates precise gluing. When gluing is completed, the drive cylinder drives the glue injection unit to move the gluing head away from the glue tank. The glue storage chamber recovers its shape after losing the squeezing force, and the glue remaining on the surface is recovered, which helps to reduce glue waste.

[0008] Preferably, the glue injection part is provided with a glue injection channel, the glue injection part is provided with a clamping block, the glue coating head includes a glue coating part and a mounting plate, the glue coating part is provided with a clamping slot, one end of the clamping block passes through the mounting plate and is clamped into the clamping slot from bottom to top for positioning, the glue storage cavity is formed by splicing the glue coating part and the mounting plate, the mounting plate is provided with a connecting port connected to the glue injection channel, the glue upper groove and the glue outlet are both provided in the glue coating part, so as to facilitate the recovery of residual glue in the glue coating part.

[0009] By adopting the above technical solution, during the gluing process, the gluing head is inserted into the glue groove to apply glue to the rotor. When the device completes gluing, the gluing head is moved from bottom to top to disengage the card block from the card groove, and the gluing head is removed, so as to facilitate the cleaning and recycling of the residual glue in the gluing head, and prevent the glue from solidifying and clogging the glue storage port due to excessive downtime, which is beneficial to improving the service life of the gluing head.

[0010] Preferably, the glue coating part includes an elastic bin and a glue storage box, the elastic bin protrudes from one end of the glue storage box close to the mounting seat, the elastic bin and the glue storage box are connected, the elastic bin can restore its shape by its own elasticity after the external force is removed, the glue applying groove and the glue outlet are opened in the elastic bin, the glue outlet is connected to the inside of the glue storage box, a scraper ring is slidingly connected in the glue storage box, the scraper ring is connected to the elastic bin, the scraper ring fits the inner wall of the glue storage box, and the deformation of the elastic bin drives the scraper ring to move.

[0011] By adopting the above technical solution, during actual gluing, the elastic bin is deformed and stuck into the glue groove. When it is necessary to clean the residual glue inside the gluing head, the gluing head is removed, and the elastic bin is squeezed to drive the scraper ring to move, so as to facilitate scraping the residual glue inside the glue storage box to the outlet of the glue storage cavity.

[0012] Preferably, a pressure glue storage tank is provided on the operating table, the glue injection part is connected to the pressure glue storage tank, the glue outlet is located on the moving path of the scraper ring, and when the elastic bin is not deformed, the scraper ring covers the glue outlet.

[0013] By adopting the above technical solution, during the operation of the device, after one gluing operation is completed, the glue continues to be squeezed out under the action of the residual pressure. At this time, the scraper ring covers the glue outlet to reduce the outflow of glue from the glue outlet.

[0014] Preferably, a return pipe is provided on the mounting plate, and the return pipe is connected to the interior of the glue storage box. A sealing column is slidingly connected on the mounting plate, and the sliding direction of the sealing column is parallel to the distribution direction of the glue storage box and the mounting plate. A spring pad is provided on the mounting plate, and the spring pad makes the sealing column have a tendency to extend into and block the return pipe.

[0015] By adopting the above technical solution, as the glue content inside the gluing head increases, the internal pressure of the gluing head increases. The hydraulic pressure acts on the positioning sealing column, causing the sealing column to move and open the return pipe, allowing the glue inside the gluing head to enter the return pipe for recovery. By installing the return pipe and sealing column on the mounting plate, the device can continuously discharge glue during the gap between preparation and loading, which helps to reduce the number of times the device is started and stopped.

[0016] Preferably, a sliding groove is provided on the mounting plate for the block to pass through, and the installation enables the mounting plate to be lifted and slidably connected to the lifting part through the cooperation between the block and the sliding groove. A sealing block is provided on the mounting plate, and the mounting plate drives the sealing block to move and block the glue injection channel. A positioning ring is provided on the glue storage box, and the positioning ring is inserted into the connecting port and the glue injection channel to position the mounting plate.

[0017] By adopting the above technical solution, during the operation of the device, the glue storage box is fixed to the mounting plate and the glue injection part. When the device is finished working, the glue storage box is removed, the positioning ring is separated from the mounting plate, and the mounting plate is moved so that the sealing block blocks the glue injection channel, thereby reducing the outflow of residual glue inside the glue injection channel.

[0018] Preferably, an outer ring gear is rotatably connected to the operating table, and the outer ring gear is arranged around the mounting seat. A gear meshing with the outer ring gear is rotatably connected to the operating table, and the driving cylinder is fixed to the outer ring gear. The driving cylinder drives the glue injection part to move, and the outer ring gear supports the glue coating head.

[0019] By adopting the above technical solution, the gear is rotated, and the gear drives the outer ring gear, thereby adjusting the positions of several gluing heads so that the gluing heads correspond to the glue grooves. When the number of gluing heads does not correspond to the number of glue grooves, the outer ring gear is rotated so that two of the gluing heads correspond to the glue grooves, which facilitates the processing of the glue grooves on rotors of different models in pairs.

[0020] Preferably, the mounting plate slides and fits against the operating table surface, and the blocking block is located between the mounting plate and the glue injection portion.

[0021] By adopting the above technical solution, after removing the gluing part, the mounting plate is attached to the operating table surface, and the mounting plate is driven by the outer gear ring and the drive cylinder to move on the operating table surface to clean the glue stains.

[0022] Preferably, the glue injection part is slidably connected to the driving cylinder, and a positioning piece is provided on the glue injection part, and the positioning piece is used to position the glue injection part and the driving cylinder.

[0023] By adopting the above technical solution, it is convenient to adjust the distance of the gluing head mounting seat according to the diameter of the rotor of different models, which is conducive to improving the applicability of the device.

[0024] The advantages of the present invention compared to the prior art are:

[0025] 1. The gluing head of the present invention has the ability of elastic deformation, which is conducive to adapting to glue tanks of different sizes. The gluing tank is located in the glue tank during gluing, which is convenient for accurate gluing. When gluing is completed, the driving cylinder drives the glue injection part to move the gluing head out of the glue tank. The glue storage cavity recovers its shape after losing the squeezing force, and the glue remaining on the surface is recovered, which is conducive to reducing glue waste.

[0026] 2. When the present invention is actually applying glue, the elastic bin is deformed and stuck in the glue tank. When it is necessary to clean the residual glue inside the glue head, the glue head is removed and the elastic bin is squeezed to drive the scraper ring to move, so as to facilitate scraping the residual glue inside the glue storage box to the glue storage cavity outlet;

[0027] 3. After the gluing part is removed from the present invention, the mounting plate is attached to the operating table surface, and the mounting plate is driven by the outer gear ring and the driving cylinder to move on the operating table surface to clean the glue stains.

[0036] A motor rotor, see Figure 1 , including a rotor body 81 and a plurality of magnetic steels 82. The rotor body 81 is provided with a plurality of glue grooves 83 for the magnetic steels 82 to be snapped into position.

[0037] The present invention will be further described below with specific embodiments:

[0038] The present application discloses a motor rotor gluing device, see Figure 2 and Figure 3 , including an operating table 1, a mounting seat 2 and a glue injection part 3. A driving member 11 is fixed on the operating table 1, and the driving member 11 is located below the table top of the operating table 1. The mounting seat 2 is connected to the operating table 1 by lifting and sliding. The mounting seat 2 is clamped into the rotor body 81 to position the rotor body 81. The rotor body 81 is located above the mounting seat 2. The driving member 11 drives the mounting seat 2 to lift and lower, thereby driving the rotor body 81 to lift and lower. An outer gear ring 4 is rotatably connected to the table top of the operating table 1. The outer gear ring 4 is arranged around the outer periphery of the mounting seat 2, and the rotation axis of the outer gear ring 4 is arranged vertically. There are several glue injection parts 3, and the several glue injection parts 3 are evenly distributed around the mounting seat 2 at equal intervals. A plurality of driving cylinders 41 are fixed above the outer gear ring 4. The position and number of the driving cylinders 41 correspond one-to-one to the position and number of the glue injection parts 3. The driving cylinders 41 drive the corresponding glue injection parts 3 to slide closer to or away from the mounting seat 2, and the outer gear ring 4 supports the glue injection parts 3. One end of the glue injection portion 3 close to the mounting seat 2 is connected to a glue coating head 5 for coating the glue groove 83 with glue. The height of the glue coating head 5 is lower than the highest height of the mounting seat 2 , and the mounting seat 2 drives the rotor body 81 to enter between the glue coating heads 5 .

[0039] In this embodiment, the driving member 11 is an electric push rod, and in other embodiments, it can also be a linear motor, an electric push rod, etc. In this embodiment, the number of the glue coating heads 53 is 8.

[0040] See also Figure 2 and Figure 3 A gear 42 is rotatably connected to the operating table 1. The gear 42 is located outside the outer gear ring 4. The rotation axis of the gear 42 is parallel to the rotation axis of the outer gear ring 4, and the gear 42 meshes with the outer gear ring 4. A servo motor 12 is fixed to the operating table 1. The servo motor 12 is used to drive the gear 42 to rotate, and then drive the outer gear ring 4 to rotate through the gear 42.

[0041] The number of magnets 82 varies in different rotor models, but is always an even number. When the number of magnets 82 corresponds to the number of glue applicators 5, and when the rotor body 81 is fixed to the mounting base 2, the positions of the glue grooves 83 correspond to those of the glue applicators 5, and the drive cylinder 41 drives several glue applicators 5 to apply glue to the glue grooves 83 simultaneously. When the number of magnets 82 is less than the number of glue applicators 5, for example, four, the gear 42 drives the outer ring gear 4 to rotate so that two glue applicators 5 are aligned with the glue grooves 83. After gluing is completed in two glue grooves 83, the outer ring gear 4 is rotated to apply glue to the remaining two glue grooves 83. This helps improve applicability.

[0042] See also Figure 2 and Figure 4 The piston rod of the drive cylinder 41 is slidably connected to the corresponding glue injection unit 3. The glue injection unit 3 is provided with a positioning member 31, which secures the glue injection unit 3 to the piston rod of the drive cylinder 41 via the positioning member 31. The drive cylinder 41 is used to drive the glue coating head 5 into the glue tank 83. The positioning member 31 is a positioning rod 311. A slider 411 is slidably connected to the piston rod of the drive cylinder 41. The glue injection unit 3 is provided with a sliding groove 32 for the slider 411 to engage. The glue injection unit 3 is provided with a plurality of positioning holes 33, which are arranged parallel to the sliding direction of the glue injection unit 3. The positioning holes 33 are located above and communicate with the sliding groove 32. The slider 411 is provided with a slot 312. The slider 411 moves to connect the slot 312 with the positioning hole 33. The slot 312 is located below the positioning hole 33 and is engaged with the positioning rod 311. In other embodiments, the positioning member 31 is a screw or bolt.

[0043] When it is necessary to apply glue to the rotor body 81 of different diameters, the positioning rod 311 is removed from the positioning hole 33 and the slot 312, and the glue injection part 3 is moved to adjust the distance between the glue application head 5 and the mounting seat 2, and the slot 312 is aligned with the positioning hole 33. After the adjustment is completed, the positioning rod 311 is inserted into the positioning hole 33 and the slot 312 for fixation, and the driving cylinder 41 drives the glue injection part 3 to be inserted into the glue groove 83.

[0044] See also Figure 1A pressure glue storage tank 13 for storing glue is placed on the operating table 1. The glue injection part 3 is connected to the pressure glue storage tank 13 through a hose 14. A booster pump for increasing the air pressure in the pressure glue storage tank 13 is installed on the pressure glue storage tank 13, so that the glue flows into the glue injection part 3 under pressure.

[0046] See also Figure 2 and Figure 5 The glue applying head 5 includes a glue applying part 51 and a mounting plate 52. The glue applying part 51 includes an elastic bin 511 and a glue storage box 512. The mounting plate 52 is connected to the glue applying part 51. The elastic bin 511 is located on the side of the glue storage box 512 close to the mounting seat 2. The elastic bin 511 and the glue storage box 512 are fixed. The mounting plate 52 is located between the glue injection part 3 and the glue storage box 512. The glue storage cavity 513 is formed by splicing the elastic bin 511, the glue storage box 512 and the mounting plate 52. The connecting port 521 is opened on the mounting plate 52. The mounting plate 52 covers the glue storage cavity 513. The mounting plate 52 and the glue storage box 512 are detachably connected. The elastic bin 511 can restore its shape by its own elasticity after the external force is removed. The end of the elastic bin 511 close to the mounting seat 2 protrudes in a circular arc surface in the direction close to the mounting seat 2. The elastic bin 511 is used to be stuck in the glue groove 83 for glue application.

[0047] See also Figure 6 The mounting plate 52 is provided with a slot 522. A clamping block 35 is fixed to the glue injection unit 3. The clamping block 35 passes through the slot 522 and extends out of the mounting plate 52 at the end near the glue storage box 512. The vertical length of the clamping slot 5121 is greater than the vertical length of the clamping block 35. The lower end surface of the glue storage box 512 is provided with a clamping slot 5121. The end of the clamping block 35 near the glue storage box 512 is bent upward into an L shape. The clamping block 35 is clamped into the clamping slot 5121 from bottom to top, thereby fixing the glue storage box 512. One end of the card block 35 that is inserted into the card slot 5121 is slidably connected to the positioning block 351. The sliding direction of the positioning block 351 is parallel to the distribution direction of the positioning glue storage box 512 and the mounting plate 52. A rubber pad 352 is fixed on the card block 35. The rubber pad 352 presses against the positioning block 351 so that the positioning block 351 protrudes from the card block 35. A positioning groove 5122 for the positioning block 351 to be inserted is provided on the inner wall of the card slot 5121. One end of the card block 35 at the convex part of the positioning block 351 is an arc surface. The inner wall of the positioning groove 5122 fits the positioning block 351 after the card block 35 is inserted.

[0048] See also Figure 5 and Figure 7A sealing block 523 is fixed at one end of the mounting plate 52 close to the glue injection part 3, and the sealing block 523 protrudes from the mounting plate 52. When the glue storage box 512 is fixed to the glue injection part 3, the sealing block 523 is located above the glue injection part 3, and the connecting port 521, the glue storage cavity 513 and the glue injection channel 34 are connected. The glue storage box 512 and the glue injection part 3 are pressed against the opposite ends of the mounting plate 52 to position the mounting part; after the glue storage box 512 is removed from the glue injection part 3, the mounting plate 52 is first moved away from the glue injection part 3, and then the mounting plate 52 is moved downward so that the sealing block 523 is located between the mounting plate 52 and the glue injection part 3, and the bent end of the clamping block 35 is pressed against the mounting plate 52, so that the sealing block 523 is pressed against the glue injection part 3 to seal the glue injection channel 34. When the sealing block 523 seals the glue injection channel 34 , the lower end surface of the mounting plate 52 is in contact with the surface of the positioning operating table 1 , and the outer gear ring 4 rotates to drive the plurality of mounting plates 52 to move around the mounting seat 2 to clean the glue stains on the surface of the operating table 1 .

[0049] During the actual production process, the shape of the mounting plate 52 can be changed to increase the contact area with the surface of the operating table 1, and a sealing ring can be added between the glue storage box 512 and the mounting plate 52 to improve the sealing strength.

[0050] See also Figure 5 and Figure 6 The elastic bin 511 is provided with a glue groove 5111 at one end near the installation, and the glue groove 5111 passes through the upper end surface of the elastic bin 511. A glue outlet 5112 is provided on the elastic bin 511, and the glue outlet 5112 is located on the side of the glue groove 5111 close to the glue storage box 512. The glue outlet 5112 extends toward the glue storage box 512 and is connected with the inside of the glue storage box 512. The glue groove 5111 and the glue storage cavity 513 are connected through the glue outlet 5112. When the elastic bin 511 is stuck in the glue groove 83, the glue groove 5111 is located in the glue groove 83, and the glue overflows from the glue groove 5111 to glue the glue groove 83.

[0051] See face Figure 5 A scraper ring 6 is slidably connected to the glue storage box 512. The sliding direction of the scraper ring 6 is parallel to the distribution direction of the glue storage box 512 and the mounting plate 52. The outer ring surface of the scraper ring 6 fits the four inner walls of the glue storage box 512 that are distributed perpendicular to the sliding direction of the scraper ring 6. A connecting rod 61 is integrally formed on the end of the scraper ring 6 away from the mounting plate 52. The connecting rod 61 is fixed to the inner wall of the elastic chamber 511 away from the glue storage box 512. The end of the glue storage port close to the mounting plate 52 is located in the movement path of the scraper ring 6. When the elastic chamber 511 is not pressurized, the scraper ring 6 covers the glue outlet 5. When the elastic chamber 511 is stuck in the glue groove 83, the elastic chamber 511 is squeezed and deformed, driving the scraper to move away from the elastic chamber 511 through the connecting rod 61 to open the glue outlet 51.

[0052] See also Figure 4 and Figure 5A return pipe 7 is fixed on the mounting plate 52, and the return pipe 7 is connected to the glue storage chamber 513. The other end of the return pipe 7 is connected to the pressure glue storage tank 13. An overflow valve 71 is fixed between the mounting plate 52 and the return pipe 7. The overflow valve 71 is used to control the connection between the return pipe 7 and the glue storage chamber 513. When the pressure in the glue storage chamber 513 is too high and exceeds the preset value, the overflow valve 71 connects the return pipe 7 and the glue storage chamber 513, and the excess glue is recovered from the return pipe 7; when the pressure in the glue storage chamber 513 is less than the preset value, the overflow valve 71 disconnects the connection between the return pipe 7 and the glue storage chamber 513, so that after the elastic bin 511 is squeezed, the glue flows out from the glue outlet 5112.

[0053] In the embodiment of the present application, the elastic chamber 511 is made of rubber, and in other embodiments it can also be made of nylon.

[0054] The implementation principle of the embodiment of the present application is: during the actual glue injection process, since the glue coating head 5 has the ability of elastic deformation, it can be deformed and stuck into glue grooves 83 of different sizes, so that when coating, the upper glue groove 5111 is located in the corresponding glue groove 83, and it is not easy to coat the glue out of the glue groove 83, which facilitates accurate glue coating; when the glue coating is completed, the driving cylinder 41 drives the glue injection part 3 to move the glue coating head 5 away from the glue groove 83, and the glue storage cavity 513 recovers its shape after losing the extrusion force. During the process of recovering the shape, the glue remaining in the upper glue groove 5111 is recovered through the glue outlet 5112, which is beneficial to reduce glue waste.

[0055] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
