Description

Technical Field

[0001] The invention relates to the field of rotor component painting processing, in particular to an anti-rust paint uniform distribution device for a motor rotor component. Background Art

[0002] When the rotor assembly of the motor is assembled into the interior of the motor housing, a layer of anti-rust paint needs to be applied to the rotor core of the rotor assembly to prevent the rotor core from rusting and causing damage to the motor.

[0003] The anti-rust paint is usually applied manually or by an automated mechanical brushing process. The anti-rust paint is relatively viscous. After the application is completed, the surface of the rotor core will be covered with a relatively uniform anti-rust paint coating. The existing automated mechanical painting is to place the rotor assembly on a rack, and then rotate a paint roller inside the rack. The paint roller absorbs the anti-rust paint and contacts the outer wall of the rotor assembly to rotate. During the rotation process, the anti-rust paint can be evenly applied to the surface of the rotor assembly.

[0004] However, the surface of the paint roller is made of an absorptive material (such as a sponge, cotton cloth, etc.), and its overall size will change after absorbing the anti-rust paint. If the absorptive material on the surface of the paint roller becomes thick after absorbing the anti-rust paint, the painting on the surface of the rotor assembly will be an extrusion-type painting, and the surface of the rotor assembly will be continuously squeezed during the painting process, causing the anti-rust paint to drip, i.e., it cannot be guaranteed that the thickness of the anti-rust paint applied to the surface of the rotor assembly meets the requirements; if the absorptive material on the surface of the paint roller becomes compact after absorbing the anti-rust paint, it cannot fully contact the surface of the rotor assembly, which will also affect the painting quality of the anti-rust paint.

A threaded slider is fixedly arranged on the top of the sleeve 10, and the threaded slider has a horizontal reciprocating sliding effect, wherein the threaded slider is installed on a slide rail commonly used in the prior art, and is driven by a motor and a threaded rod so that the threaded slider can move back and forth with the sleeve 10, and the moving track of the threaded slider is parallel to the containing frame 1;

[0033] It also includes: a mounting unit, used for mounting and painting anti-rust paint on batches of rotor assemblies, the mounting unit being arranged inside the movable plate 3;

[0034] The suction unit is used to recycle the anti-rust paint dripping from the surface of the rotor assembly, and the suction unit is located at the bottom of the containing frame 1.

[0035] The erection unit includes two groups of inverted triangular grooves 16 opened on the facing surfaces of the two movable plates 3, each group of inverted triangular grooves 16 has a plurality of inverted triangular grooves 16, and the inverted triangular grooves 16 are linearly and equidistantly distributed. The periphery of each inverted triangular groove 16 corresponds to the interior of the movable plate 3. A V-shaped cavity is opened, and an elbow block 17 is fixedly arranged in the middle of the bottom of the V-shaped cavity, and two symmetrically distributed positioning rods 18 are fixedly arranged at both ends of the elbow block 17. The two positioning rods 18 are parallel to the two inclined surfaces of the inverted triangular groove 16, and the outside of each positioning rod 18 is slidably fitted with a limit block 19, which is slidably engaged with the V-shaped cavity, and the limit block 19 is fixedly arranged at the bottom of the V-shaped cavity. A V-shaped cavity is movably extended from one end, and a second spring 20 is fixedly arranged between each elbow block 17 and the limit block 19, and the second spring 20 is distributed on the outside of the positioning rod 18. A winding wheel 22 is rotatably arranged inside the V-shaped cavity, and the winding wheel 22 is located below the elbow block 17. A pull rope 21 is fixedly arranged between the end of the limit block 19 and the winding wheel 22, and a trigger component is also arranged between the two movable plates 3, wherein a limit ring is fixedly arranged on the outside of the elbow block 17, and when the pull rope 21 is pulled between the limit block 19 and the elbow block 17, it will pass through the limit ring, and the limit ring guides the pull rope 21.

[0036] The trigger component includes a rack 23 slidably inserted into each movable plate 3, and the rack 23 extends into the interior of the V-shaped cavity. A plurality of teeth are fixedly provided on the outer surface of the winding wheel 22, and the winding wheel 22 is movably engaged with the rack 23 through the teeth. One end of the rack 23 extending out of the interior of the movable plate 3 is in a right angle shape. Two symmetrically distributed transverse grooves are provided at one end of the frame 2, and a shift block 24 is slidably assembled between the two transverse grooves. The exposed ends of the two racks 23 are slidably assembled with the shift block 24. A limiting member is also provided between the shift block 24 and the transverse groove. The two right-angled racks 23 can be extended into the interior of the two movable plates 3 through the shift block 24, and the rack 23 can engage with the winding wheel 22 to rotate during the movement.

[0037] The limiting member includes a plurality of ratchet grooves 25 which are arranged on the upper end surface of one of the transverse grooves and are equidistantly distributed in a straight line. A stop block 26 is slidably mounted inside the end of the shift block 24 close to the ratchet groove 25. The sliding direction of the stop block 26 is perpendicular to the transverse groove. The end of the stop block 26 close to the ratchet groove 25 movably extends out of the shift block 24, and a ratchet block 27 which meshes with the ratchet groove 25 is fixedly provided on the exposed end of the stop block 26. An extension plate is fixedly provided on the outer wall of the stop block 26, and the extension plate slides through the shift block 24. A third spring 28 is provided between the end of the stop block 26 away from the ratchet block 27 and the shift block 24. In the process of pushing the rack 23 by the shift block 24, the restriction of the ratchet groove 25 on the ratchet block 27 can prevent the shift block 24 from retreating, thereby ensuring the stability of the rotor assembly mounting.

[0038] The inverted triangular groove 16 is an isosceles triangle, that is, both ends of the rotor shaft of the rotor assembly are clamped at the bottom sharp corners of the inverted triangular groove 16 .

[0039] A pad strip 14 is fixedly attached to the top end surface of the containing frame 1, two partition plates 12 are fixedly arranged inside the containing frame 1, and a telescopic plate 13 is slidably inserted between the two partition plates 12, a spring is arranged between the bottom of the telescopic plate 13 and the containing frame 1, and the two partition plates 12 divide the internal space of the containing frame 1 into a painting space and a paint dropping space. The pad strip 14 is made of silicone rubber, and grooves can be provided on its surface to increase the friction between the pad strip 14 and the rotor assembly.

[0040] Working principle: The staff will place multiple rotor assemblies that need to be painted with anti-rust paint between two movable plates 3 in sequence, and pre-adjust the spacing between the two movable plates 3 before placement, and adjust it by twisting the different-direction threaded rod 5. After the adjustment is completed, the rotor assembly is placed between two oppositely distributed inverted triangular grooves 16. After placement, the spacing between the two movable plates 3 is fine-tuned to make the spacing between the two oppositely distributed inverted triangular grooves 16 slightly larger than the length of the rotor assembly, and the spacing is controlled between 1-3mm;

[0041] Then, the two racks 23 are synchronously extended into the movable plate 3 through the shift block 24. During the extension process, the racks 23 drive the winding wheel 22 to rotate, thereby winding the pull rope 21 and moving the two limit blocks 19 toward the end of the rotor assembly, which can prevent the rotor assembly from sliding upward excessively and separating from the inverted triangular groove 16.

[0042] After the above steps are completed, the protrusion 6 on the outside of the frame 2 is sleeved inside the ferrule block 8. At this time, the first spring 11 elastically squeezes the gantry 7, so that the rotor shaft surfaces of several rotor assemblies can be closely fitted on the pad 14. When the threaded slider moves with the sleeve 10, the synchronous movement of the frame 2 and the movable plate 3 causes the rotor assembly to roll on the top of the accommodating frame 1. Since the stator core of the rotor assembly has a large outer diameter, it can extend into the interior of the accommodating frame 1, and the paint space is filled with anti-rust paint, that is, when the rotor assembly is slowly When the rotor assembly rolls slowly, the surface of the stator core can be evenly coated with anti-rust paint. When the frame 2 and the movable plate 3 move toward the paint-spraying space, the rotor assembly will contact the telescopic plate 13 during the rolling process. The upper end of the telescopic plate 13 is close to the paint-spraying space and is chamfered. When the rotor assembly contacts the telescopic plate 13 during the rolling process, the telescopic plate 13 will be squeezed downward. After the rotor assembly completely enters the paint-spraying space, the telescopic plate 13 will be reset again under the action of the spring, and the anti-rust paint in the paint-spraying space will continue to be isolated.

[0043] Through the above-mentioned painting method, it can be ensured that when batches of rotor assemblies are processed, a layer of anti-rust paint can be evenly applied on the surface of the stator core, and through the assembly design, when a group of rotor assemblies is painted, the ferrule block 8 can be separated from the protrusion 6, and then a group of frames 2 and movable plates 3 can be reassembled to place another group of rotor assemblies that need to be painted.

[0044] In the above scheme, rotor assemblies of different models and lengths can be painted, which has strong applicability, and the assembled design can also improve the simplicity of the painting operation.

[0045] It should be noted in the present solution that each time the telescopic plate 13 descends, part of the anti-rust paint will flow into the paint draining space, so a liquid level sensor needs to be installed in the painting space. When the liquid level drops to a certain height, a certain amount of anti-rust paint can be automatically added to the painting space from the outside. The liquid level sensor and the structure of automatic paint replenishment are both commonly used technologies in the prior art.

[0046] Example 2: Please refer to Figure 7 and Figure 8This embodiment is a further explanation of the first embodiment. The suction unit includes a connecting pipe 34 fixedly mounted at the bottom of the paint-stripping space, and a plurality of delivery pipes fixedly mounted at the bottom of the painting space and distributed in a straight line and equidistantly. One end of the delivery pipe extending into the painting space is fixedly connected and equipped with an air disk 32. One end of the plurality of delivery pipes away from the air disk 32 is fixedly connected and provided with a sealing cylinder 30. The outside of the delivery pipe and the outside of the connecting pipe 34 are respectively fixedly mounted with a first non-return valve 31 and a second non-return valve 35. A support plate 29 is fixedly mounted below the containing frame 1, and a delivery cylinder 36 is fixedly mounted above the support plate 29. The axis of the delivery cylinder 36 is parallel to the containing frame 1. The connecting pipe 34 is away from the containing frame 1. One end of the frame 1 is fixedly connected to the outer wall of the conveying cylinder 36, the sealing cylinder 30 is connected to the opposite ends of the conveying cylinder 36, and the interior of the conveying cylinder 36 is slidably equipped with a piston disk 37, and the end of the piston disk 37 away from the sealing cylinder 30 is fixedly provided with a feeler rod 39 that slides through the conveying cylinder 36, and a first tension spring 38 is also fixedly provided between the end of the piston disk 37 away from the sealing cylinder 30 and the conveying cylinder 36, and the upper end surface of the support plate 29 is also fixedly provided with a motor 33, and the outer surface of the output end of the motor 33 is fixedly covered with a cam 40 that pushes the feeler rod 39. The push of the cam 40 on the feeler rod 39 cooperates with the action of the first tension spring 38 to realize the reciprocating movement of the piston disk 37 inside the conveying cylinder 36.

[0047] The bottom surface of the paint-stripping space is provided with a slope portion 15. The flow direction of the first one-way valve 31 is one-way flow from the sealing cylinder 30 to the painting space, and the flow direction of the second one-way valve 35 is one-way flow from the paint-stripping space to the conveying cylinder 36. Through the action of the two one-way valves, the anti-rust paint accumulated in the paint-stripping space can be sucked and conveyed to the painting space.

[0048] In this embodiment: the design of the slope portion 15 can gather the anti-rust paint in the paint-draining space. When the motor 33 starts to push the touch rod 39 continuously through the cam 40, the piston plate 37 can move back and forth inside the conveying cylinder 36 in cooperation with the first tension spring 38, the first one-way valve 31 and the second one-way valve 35. When moving, the anti-rust paint in the paint-draining space can be sucked and conveyed to the inside of the sealing cylinder 30, and then enters the painting space through the conveying pipe and the gas disc 32;

[0049] In this solution, all structural parts in contact with the anti-rust paint are made of Teflon material or the surfaces of the structural parts are sprayed with Teflon coating and will not be attached by the anti-rust paint.

[0050] Example 3: Please refer to Figure 7-10This embodiment is a further explanation of the first embodiment. The interior of the sealing cylinder 30 is fitted with a built-in column cylinder 42 for rotation. The interior of the built-in column cylinder 42 is hollow. The opening of the built-in column cylinder 42 faces the conveying cylinder 36. The built-in column cylinder 42 and the conveying cylinder 36 are connected to each other through a rotating sealing joint. The outer surface of the built-in column cylinder 42 is provided with a plurality of connecting holes 43 distributed in a spiral shape at equal angles. The number of the connecting holes 43 is consistent with the number of the conveying pipes. Among them, only one group of the connecting holes 43 and the conveying pipes can be connected and conveyed at the same time, that is, the multiple groups of connecting holes 43 and the conveying pipes alternately convey the medium entering the built-in column cylinder 42.

[0051] A movable ratchet gear 44 is also fixedly mounted on the outer surface of the open end of the built-in column 42, and a ratchet plate 45 is assembled on the outside of the movable ratchet gear 44. The ratchet plate 45 slides vertically through the support plate 29, and a chuck 49 is fixedly mounted on the bottom of the ratchet plate 45. A second tension spring 50 is fixedly mounted between the chuck 49 and the bottom of the support plate 29. A gear differential 41 is fixedly mounted on the upper end surface of the support plate 29. The output end of the motor 33 is fixedly docked with the input end of the gear differential 41, and a turntable 47 is fixedly mounted on the output end of the gear differential 41. A paddle 48 is fixedly mounted on the outer wall of the turntable 47. An extension rod 46 that is in movably contact with the paddle 48 is installed on the external fixing frame of the ratchet plate 45. When the ratchet plate 45 moves downward, it will not trigger the rotation of the movable ratchet gear 44. When the ratchet plate 45 moves upward, it can engage the movable ratchet gear 44 to rotate.

[0052] In this embodiment: In this scheme, considering that there are many delivery pipes, when the anti-rust paint is delivered to the interior of the painting space through the sealing cylinder 30, it is impossible to deliver it evenly to multiple delivery pipes. Therefore, in this scheme, a built-in column 42 is rotatably placed inside the sealing cylinder 30, and the outer wall of the built-in column 42 is tightly fitted with the inner wall of the sealing cylinder 30. The closed end of the built-in column 42 is a flexible silicone sealing film. Only when the connecting hole 43 on the surface of the built-in column 42 is connected to the end of the delivery pipe, can the anti-rust paint be delivered into the painting space;

[0053] In this embodiment, the number of the delivery pipe and the communicating hole 43 is five, and the angle between the five communicating holes 43 distributed in a threaded manner is 72 degrees. Figure 7 and attached Fig.10When the connecting hole 43 at the far left end is connected with the corresponding delivery pipe, the delivery tube 36 delivers the anti-rust paint to the inside of the built-in column 42, and then enters the painting space through the connecting hole 43 at the far left end and the delivery pipe. During the continuous driving process, the motor 33 can drive the turntable 47 to rotate slowly through the gear differential 41. During the rotation process, the extension rod 46 and the ratchet plate 45 can be pressed down by the paddle 48. When the paddle 48 is separated from the extension rod 46, the ratchet plate 45 can be quickly reset upward under the action of the second tension spring 50, and the meshing active ratchet gear 44 can be rotated 72 degrees. That is, after the built-in column 42 rotates 72 degrees, the next group of connecting holes 43 and the delivery pipe can be connected, so that another gas disc 32 can deliver anti-rust paint to the painting space.

[0054] Through the above-mentioned alternate delivery method, multiple gas discs 32 can work alternately, and the alternating work can make the bottom liquid of the painting space alternately mixed, thereby avoiding the deposition of anti-rust paint in the painting space;

[0055] During the conveying process, if the medium conveyed by the conveying cylinder 36 into the built-in column cylinder 42 is a gas-liquid mixture, the gas disk 32 can input the gas-liquid mixture at the bottom of the painting space, and the gas is injected from the bottom of the painting space, which can better improve the mixing effect of the anti-rust paint in the painting space and avoid the precipitation of the anti-rust paint.
