Description

Technical Field

[0001] The invention relates to the field of motor parts cleaning, in particular to a rotor processing device for motor production. Background Art

[0002] Rotor laminations are crucial components in motor rotor structures, and their surface cleanliness can impact subsequent assembly processes and operational performance. In actual production, rotor laminations are typically produced in batches using dies and stacked. During this process, oil, dust, or fine particles may adhere to the lamination surfaces. Therefore, laminations typically require cleaning before assembly.

[0003] Existing cleaning methods often use immersion, ultrasonic cleaning, or spray rinsing. In practice, wafers often enter the cleaning process in a stacked state. In this state, the contact between the cleaning liquid and the intermediate wafers may be limited, resulting in uneven cleaning results and difficulty removing impurities in some areas, affecting cleaning efficiency.

[0004] Furthermore, the spray mechanism of some cleaning devices has a relatively fixed spray direction during operation, with a limited range of spray angle adjustment. When the punching sheet has local structures such as holes or grooves, the cleaning liquid may not be able to cover the entire surface, resulting in suboptimal cleaning results in certain areas. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing cleaning device, such as insufficient contact of the cleaning liquid when the punching sheets are stacked and the fixed spray direction, which easily leads to incomplete local cleaning and affects the cleaning effect, it is necessary to provide a rotor processing device for electric motor production, which can realize the single-piece release of the rotor punching sheet and the adjustment of the cleaning liquid spray angle, which helps to avoid the cleaning blind spots caused by the stacking of multiple punching sheets, and at the same time enhance the coverage of the cleaning liquid on different structural surfaces of the punching sheet, thereby improving the cleaning uniformity and processing efficiency.

Three guide holes are opened on the top of the hollow tube. The pressure cover is detachably inserted into the guide holes by sliding through the three protrusions.

[0015] The beneficial effects of the present invention are as follows: 1. The servo motor drives the gear mechanism, the hollow vertical shaft, the grooved plate and the concave column to rotate synchronously, and the grooved plate drives the roller to move, so that the baffle is retracted toward the center, and the groove on the concave column is out of contact with the vertical roller, pushing the vertical roller and the corresponding support plate to expand outward. When the support plate is pressed against the rotor punching above, the baffle completes the retraction and retracts into the hollow tube, so that the lower channel is opened, and only the bottom punching is allowed to slide to the bottom of the cylinder under the action of gravity; this method is combined with the cleaning liquid continuously sprayed out of the porous tube to clean the single rotor punching, which helps to avoid overlapping and accumulation caused by the simultaneous falling of multiple punchings, and reduces cleaning blind spots.

[0016] 2. The hollow vertical shaft drives the corrugated groove ring to rotate, and the corrugated groove drives the cross roller, slide bar and rack assembly to reciprocate up and down, driving the six semi-arc teeth and six pendulum pieces to swing synchronously. The inward and outward swing of the pendulum piece forms a double limit control mechanism, that is, when the pendulum piece swings outward, it prevents the punching piece from continuing to fall, and releases the limit when it swings inward, allowing the punching piece to pass smoothly. It can effectively adjust the residence time of the rotor punching piece in the hollow tube, so that it stays in the cleaning position for a certain time, ensuring that the cleaning liquid has sufficient contact with the punching piece surface, and avoiding insufficient cleaning caused by too short cleaning time or too fast sliding.

[0017] 3. The three swing arms driven by the driving gear contact the contact rollers on the swivel in turn, causing the connecting frame, swivel and four porous tubes to swing at a certain angle, while compressing the arc spring. When the swing arms leave the contact roller, the spring releases its force and automatically returns to its original position, thereby realizing the reciprocating swing of the porous tubes. The spray angle of the sprayed cleaning liquid changes continuously during operation, which can increase the cleaning coverage area, thereby further reducing cleaning dead angles and improving cleaning uniformity and overall efficiency.

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0035] Example 1: A rotor processing device for electric motor production, such as Figure 1-Figure 7 As shown, it includes a base frame 1, a cylinder 2 is installed on the base frame 1, a drain valve 3 is connected to the bottom of the cylinder 2, two slip rings 4 are rotatably provided on the base frame 1, four porous tubes 5 are evenly spaced between the two slip rings 4, the drainage parts of the four porous tubes 5 are all located in the cylinder 2, a hollow tube 6 is fixedly installed in the cylinder 2, a plurality of rotor punchings 61 are stacked on the upper part of the hollow tube 6, an intermittent mechanism is provided on the base frame 1 and the hollow tube 6, the intermittent mechanism is used to intermittently control the unloading of the rotor punching 61, a tightening mechanism is provided on the hollow tube 6 and the intermittent mechanism, the tightening mechanism is used to tighten the rotor punching 61 that does not need to be unloaded, and a lifting mechanism is provided on the base frame 1, the cylinder 2 and the hollow vertical shaft 71, the lifting mechanism is used to extract the rotor punching 61 that has been cleaned.

[0036] The intermittent mechanism includes a hollow vertical shaft 71. A hollow vertical shaft 71 is rotatably provided on the hollow tube 6. The lower end of the hollow vertical shaft 71 passes through the bottom of the hollow tube 6. A servo motor 72 is installed on the base frame 1. A driving gear 73 is installed on the output shaft of the servo motor 72. A driven gear 74 is installed at the lower end of the hollow vertical shaft 71. The driving gear 73 is engaged with the driven gear 74. A groove plate 75 is installed on the hollow vertical shaft 71. The groove plate 75 is located in the hollow tube 6. Three baffles 76 for blocking the rotor punching 61 are evenly spaced and slidingly provided on the upper part of the hollow tube 6. The three baffles 76 are in contact with one of the surfaces of the bottom rotor punching 61. A roller 77 is installed on the side of the three baffles 76 close to each other. A drive groove is opened on the side of the groove plate 75 close to the roller 77, and the three rollers 77 are all located in the drive groove.

[0037] The tightening mechanism includes a support plate 81. Three support plates 81 are evenly spaced and slidingly provided on the hollow tube 6 to support the rotor punching 61. A return spring 82 is connected between the three support plates 81 and the inner wall of the hollow tube 6. A vertical roller 83 is rotatably provided on the side where the three support plates 81 are close to each other. A concave column 84 is slidingly provided on the upper part of the hollow vertical shaft 71, and a vertical spring 85 is connected between the top of the concave column 84 and the hollow vertical shaft 71.

[0038] The concave column 84 is provided with three grooves. During the rotation of the concave column 84 , the three grooves can respectively contact or disengage with the three vertical rollers 83 at the same time.

[0039] The tops of the three vertical rollers 83 are arc structures, and the bottoms of the concave columns 84 are arc structures.

[0040] The lifting mechanism includes a moving pair 91. Two moving pairs 91 are installed on the base frame 1. Each moving pair 91 is composed of a guide rail, a drive motor, a screw and a slider. A slide 92 is installed between the sliders on the two moving pairs 91. The slide 92 slides through the bottom of the cylinder 2. A push ring 93 for pushing out the rotor punching 61 is installed on the slide 92. The push ring 93 is located at the bottom of the cylinder 2. A slide rod 94 is slidably provided in the hollow vertical shaft 71. The top end of the slide rod 94 is connected to the bottom of the concave column 84, and the bottom end of the slide rod 94 is located above the slide 92. The slide 92 will contact the bottom end of the slide rod 94 during movement.

[0041] First, the operator opens the drain valve 3 and introduces the cleaning liquid into the four porous tubes 5 through the external liquid inlet pipe; the cleaning liquid is sprayed from the porous tube 5 into the interior of the cylinder 2 and discharged through the drain valve 3 to achieve pre-cleaning of the cylinder 2. Subsequently, the operator places an appropriate amount of rotor punchings 61 into the hollow tubes 6 in sequence; the rotor punching 61 at the bottom contacts the three baffles 76, and the remaining rotor punchings 61 are stuck in the open state of the three support plates 81, but will not interfere with the rotor punching 61 at the bottom. The operator starts the servo motor 72, and the servo motor The output shaft of the machine 72 drives the driving gear 73 to rotate, which in turn drives the driven gear 74, the hollow vertical shaft 71, the grooved plate 75 and the concave column 84 to rotate synchronously; as the grooved plate 75 rotates, the three rollers 77 drive the three blocking pieces 76 to move towards each other; at the same time, the three grooves on the concave column 84 break away from the contact with the vertical rollers 83, so that the concave column 84 pushes the three vertical rollers 83 and the corresponding support plates 81 to move away from each other; when the three support plates 81 press against the upper part of the rotor punching 61, the three blocking pieces 76 complete the retraction and retract. The hollow tube 6 is provided with a hollow tube 6. At this time, under the action of gravity, the rotor punching 61 at the bottom slides down to the bottom of the cylinder 2 under the guidance of the hollow tube 6. The hollow vertical shaft 71, the grooved plate 75 and the concave column 84 continue to rotate, and the three blocking pieces 76 move outward and extend out of the hollow tube 6 again. The support plate 81 is reset inward with the cooperation of the vertical roller 83, loosening the support for the upper rotor punching 61, so that all the rotor punchings 61 move downward as a whole. In this process, the rotor punching 61 at the bottom contacts the three blocking pieces 76 again. By intermittent discharge, only one piece is released at a time. The rotor punching 61 falls, and the porous tube 5 continuously sprays cleaning liquid to clean the single rotor punching 61, preventing the stacking of multiple pieces from affecting the cleaning effect; the cleaned rotor punching 61 falls one by one and is stacked on the push ring 93 at the bottom of the cylinder 2, and the waste liquid is discharged through the drain valve 3 to prevent the punching from being soaked for a long time; when all the rotor punchings 61 are cleaned, the operator controls the rotation of the groove plate 75 and the concave column 84 to the positioning state through the servo motor 72, so that the three blocking pieces 76 are in the retracted state and the three support plates 81 are in the extended state;Then the two moving pairs 91 are started, and the two moving pairs 91 drive the slide 92, the push ring 93 and the rotor punching 61 that has been cleaned and stacked together to move upward. After the slide 92 moves, it pushes the slide bar 94 and the concave column 84 to move upward, and the vertical spring 85 is compressed accordingly. After the concave column 84 moves upward, it disengages from the three vertical rollers 83, and under the action of the return spring 82, the three support plates 81 move toward each other and reset, so that the rotor punching 61 that has been cleaned and stacked together can be smoothly taken out of the hollow tube 6. After the rotor punching 61 that has been cleaned and stacked together is taken out, the two moving pairs 91 drive the slide 92 and the push ring 93 to move downward and reset. After the slide 92 moves, it disengages from the slide bar 94, and under the action of the vertical spring 85, the slide bar 94 and the concave column 84 move downward and reset. The elastic force of the vertical spring 85 is greater than the return spring 82, and the bottom of the concave column 84 with the arc surface structure contacts the arc surface of the three vertical rollers 83, so that the three support plates 81 are opened again, and are ready for the next cleaning.

[0042] Example 2: Based on Example 1, Figures 8-11 As shown, it also includes a blocking mechanism provided on the hollow tube 6 and the hollow vertical shaft 71, the blocking mechanism is used to block the rotor punching 61 so that the rotor punching 61 can temporarily stay on the hollow tube 6, the blocking mechanism includes a cross bar 101, six cross bars 101 are provided in the hollow tube 6, three cross bars 101 located at the same horizontal plane form a group, each cross bar 101 is rotatably provided with a pendulum 102, three pendulums 102 located at the same horizontal plane form a group, the pendulum 102 is slidably embedded in the hollow tube 6, three slide bars 103 are slidably provided in the hollow tube 6, and three slide bars 103 in each group A semi-arc tooth 104 is installed on the side where each pendulum piece 102 is close to each other, and two vertical racks 105 are installed on the side where the three slide bars 103 are away from each other. The six vertical racks 105 are respectively engaged with the six semi-arc teeth 104. The upper and lower parts of the three slide bars 103 are rotatably provided with a horizontal roller 106. Two corrugated groove rings 107 are installed on the hollow vertical shaft 71. The corrugated groove rings 107 have corrugated grooves. The three upper horizontal rollers 106 are located in the corrugated grooves on the upper corrugated groove ring 107, and the three lower horizontal rollers 106 are located in the corrugated grooves on the lower corrugated groove ring 107.

[0043] During the cleaning process, the hollow vertical shaft 71 also synchronously drives the two corrugated groove rings 107 to rotate. The corrugated grooves on the corrugated groove rings 107 drive the six cross rollers 106 and the three slides 103 to move back and forth. The three slides 103 drive the six vertical racks 105 to do reciprocating motion, thereby driving the six semi-arc teeth 104 and the six pendulum pieces 102 to swing back and forth synchronously; when the pendulum piece 102 swings outward, it blocks the rotor punching piece 61 from falling; when the pendulum piece 102 swings inward, the limit is released, allowing the punching piece to continue falling; through two intermediate limit controls, the cleaning residence time of the rotor punching piece 61 on the hollow tube 6 can be extended, thereby improving the cleaning effect.

[0044] Example 3: Based on Example 2, Figure 12-15 As shown, it also includes a reciprocating mechanism arranged on the cylinder 2, the slip ring 4 and the driving gear 73. The reciprocating mechanism is used to drive the porous tube 5 to swing back and forth. The reciprocating mechanism includes a rotating ring 111. The rotating ring 111 is slidingly provided at the bottom of the cylinder 2. A connecting frame 112 is connected between the rotating ring 111 and one of the slip rings 4. Three rocking rods 113 are evenly spaced on the driving gear 73. A contact roller 114 is rotatably provided on the rotating ring 111. During the rotation process, the three rocking rods 113 will contact the contact roller 114 in turn and then separate. An arc spring 115 is connected between the connecting frame 112 and the bracket.

[0045] The hollow tube 6 further comprises a pressure cover 12 , which is provided with three bosses. The hollow tube 6 has three guide holes 13 at the top. The pressure cover 12 is detachably inserted into the guide holes 13 by sliding through the three bosses.

[0046] During the cleaning process, the rotation of the driving gear 73 also drives the three rocker arms 113 to rotate synchronously. When the rocker arms 113 contact the contact rollers 114 on the rotating ring 111 in turn, the contact rollers 114 drive the connecting frame 112, the rotating ring 111 and the four porous tubes 5 to swing, causing the four porous tubes 5 to swing at a certain angle, and the arc springs 115 are compressed; after the rocker arms 113 are separated from the contact rollers 114, the arc springs 115 release their force to return the rotating ring 111 and the four porous tubes 5 to their original positions; this cycle is repeated to achieve periodic changes in the spray angle of the cleaning liquid, thereby improving the cleaning uniformity and efficiency.

[0047] When placing the rotor punching 61, the operator first removes the pressure cover 12 and places several rotor punchings 61 into the hollow tube 6 in sequence, so that the bottom rotor punching 61 contacts the three baffles 76; then, the three protrusions on the pressure cover 12 are inserted into the guide holes 13 at the top of the hollow tube 6, and the rotor punching 61 is pressed tightly under the action of its own gravity, so that the bottom punching is always close to the baffle 76, avoiding insufficient pressure due to the reduction in the number of rotor punchings 61 and affecting the intermittent control effect.
