A rotor processing device for motor production

Abstract

This invention relates to the field of motor parts cleaning, and more particularly to a rotor processing device for motor production. Existing cleaning devices suffer from insufficient contact of the cleaning fluid when laminations are stacked, and the fixed spray direction easily leads to incomplete cleaning in certain areas, affecting the cleaning effect. The proposed rotor processing device for motor production includes a base frame with a cylinder mounted on it. A drain valve is connected to the bottom of the cylinder, and two slip rings are rotatably mounted on the base frame. A servo motor drives a gear mechanism, a hollow vertical shaft, a grooved disc, and a concave column to rotate synchronously. The grooved disc drives the roller to move, causing the baffle to retract towards the center while the groove on the concave column disengages from contact with the vertical roller. When the support plate presses against the upper rotor lamination, the baffle retracts and retracts into the hollow tube, allowing only the bottom lamination to slide down to the bottom of the cylinder under gravity. This allows for cleaning of single rotor laminations, helping to avoid overlapping and accumulation caused by multiple laminations falling simultaneously, and reducing cleaning blind spots.

Description

Technical Field

[0001] This invention relates to the field of motor parts cleaning, and more particularly to a rotor processing device for electric motor production. Background Technology

[0002] Rotor laminations are crucial components in the motor rotor structure, and the cleanliness of their surfaces can affect subsequent assembly processes and operational performance. In actual production, rotor laminations are typically batch-pressed using molds and collected in stacks. During this process, oil, dust, or fine particles may adhere to the lamination surfaces. Therefore, the laminations usually need to be cleaned before entering the assembly process.

[0003] Existing cleaning methods mostly employ methods such as overall immersion, ultrasonic cleaning, or spray rinsing. In practical applications, wafers are often introduced into the cleaning process in a stacked state. In this state, the contact between the cleaning fluid and the middle layer of wafers may be limited, the cleaning effect may not be uniform, and it may be difficult to remove impurities in some areas, thus affecting the cleaning efficiency.

[0004] Furthermore, the spraying structure of some cleaning devices has a relatively fixed spraying direction during operation, and the range of spraying angle adjustment is limited. When there are local structures such as holes or grooves on the laminations, the cleaning fluid may not be able to cover the entire surface, and the cleaning effect in some areas may be unsatisfactory. Summary of the Invention

[0005] To overcome the shortcomings of existing cleaning devices, such as insufficient contact of cleaning fluid when laminations are stacked and fixed spray direction, which easily leads to incomplete cleaning in certain areas and affects the cleaning effect, a rotor processing device for electric motor production is needed. This device can realize the release of individual rotor laminations and adjust the spray angle of cleaning fluid, which helps to avoid cleaning blind spots caused by multiple laminations being stacked, while enhancing the coverage of cleaning fluid on different structural surfaces of the laminations, thereby improving cleaning uniformity and processing efficiency.

[0006] Technical solution: A rotor processing device for electric motor production includes a base frame, a cylinder mounted on the base frame, a drain valve connected to the bottom of the cylinder, two slip rings rotatably mounted on the base frame, four perforated pipes evenly spaced between the two slip rings, the drainage parts of the four perforated pipes are all located inside the cylinder, a hollow pipe is fixedly installed inside the cylinder, an intermittent mechanism is provided on the base frame and the hollow pipe, a tensioning mechanism is provided on the hollow pipe and the intermittent mechanism, and a material lifting mechanism is provided on the base frame, the cylinder and the hollow vertical shaft.

[0007] As a preferred embodiment of the present invention, the intermittent mechanism includes a hollow vertical shaft, which is rotatably mounted on a hollow tube. The lower end of the hollow vertical shaft extends through the bottom of the hollow tube. A servo motor is mounted on the base frame, and a drive gear is mounted on the output shaft of the servo motor. A driven gear is mounted on the lower end of the hollow vertical shaft, and the drive gear meshes with the driven gear. A grooved plate is mounted on the hollow vertical shaft and is located inside the hollow tube. Three baffles are slidably mounted at even intervals on the upper part of the hollow tube. A roller is mounted on the side of the three baffles that is close to each other. A drive groove is opened on the side of the grooved plate that is close to the roller, and the three rollers are all located in the drive groove.

[0008] As a preferred technical solution of the present invention, the tensioning mechanism includes support plates. Three support plates are slidably arranged at even intervals on the hollow tube. Each of the three support plates is connected to a return spring between itself and the inner wall of the hollow tube. Vertical rollers are rotatably arranged on the side of each of the three support plates that are close to each other. A concave column is slidably arranged on the upper part of the hollow vertical shaft. A vertical spring is connected between the top of the concave column and the hollow vertical shaft.

[0009] As a preferred embodiment of the present invention, the concave column is provided with three grooves, and during the rotation of the concave column, the three grooves can simultaneously contact or detach from the three vertical rollers.

[0010] As a preferred embodiment of the present invention, the top of the three vertical rollers is an arc structure, and the bottom of the concave column is an arc surface structure.

[0011] As a preferred embodiment of the present invention, the material lifting mechanism includes a sliding pair. Two sliding pairs are mounted on the base frame. Each sliding pair consists of a guide rail, a drive motor, a lead screw, and a slider. A slide is installed between the sliders on the two sliding pairs. The slide slides through the bottom of the cylinder. A push ring is installed on the slide. The push ring is located at the bottom of the cylinder. A slide rod is slidably provided inside the hollow vertical shaft. The top end of the slide rod is connected to the bottom of the concave column, and the bottom end of the slide rod is located above the slide.

[0012] As a preferred embodiment of the present invention, it further includes a blocking mechanism, which includes crossbars. Six crossbars are arranged inside the hollow tube, with three crossbars on the same horizontal plane forming a group. Each crossbar is rotatably equipped with a swing plate, and three swing plates on the same horizontal plane forming a group. The swing plates are slidably embedded in the hollow tube. Three slide bars are slidably arranged inside the hollow tube. A semi-circular tooth is installed on the side of the three swing plates in each group that is close to each other, and two vertical racks are installed on the side of the three slide bars that are far from each other. The six vertical racks mesh with the six semi-circular teeth respectively. A horizontal roller is rotatably provided on the upper and lower parts of the three slide bars. Two corrugated groove rings are installed on the hollow vertical shaft. Corrugated groove rings have corrugated grooves. The three upper horizontal rollers are located in the corrugated grooves on the upper corrugated groove ring, and the three lower horizontal rollers are located in the corrugated grooves on the lower corrugated groove ring.

[0013] As a preferred embodiment of the present invention, it further includes a reciprocating mechanism, which includes a rotating ring. The rotating ring is slidably provided at the bottom of the cylinder. A connecting frame is connected between the rotating ring and one of the sliding rings. Three swing rods are evenly spaced on the drive gear. A contact roller is rotatably provided on the rotating ring. An arc spring is connected between the connecting frame and the support.

[0014] As a preferred embodiment of the present invention, it also includes a pressure cap, which has three protrusions and three guide holes at the top of the hollow tube. The pressure cap is detachably slidably inserted into the guide holes through the three protrusions.

[0015] The beneficial effects of this invention are as follows: 1. By driving the gear mechanism, hollow vertical shaft, grooved plate and concave column to rotate synchronously through the servo motor, the grooved plate drives the roller to move, so that the baffle plate retracts towards the center, while the groove on the concave column disengages from the vertical roller, pushing the vertical roller and the corresponding support plate to expand outward. When the support plate presses against the upper rotor lamination, the baffle plate retracts and retracts into the hollow tube, opening the lower channel and allowing only the bottom lamination to slide down to the bottom of the cylinder under gravity. This method, combined with the cleaning fluid continuously sprayed from the multi-hole pipe, can clean a single rotor lamination, which helps to avoid the overlapping and accumulation caused by multiple laminations falling at the same time, and reduces cleaning blind spots.

[0016] 2. The hollow vertical shaft drives the corrugated groove ring to rotate. The corrugated groove drives the horizontal roller, slide bar and rack assembly to move up and down reciprocally, which drives the six semi-circular teeth and six swing blades to swing synchronously. The inward and outward swing of the swing blades forms a two-stage limit control mechanism. That is, when the swing blade swings outward, it prevents the lamination from falling further, and when it swings inward, it releases the limit and allows the lamination to pass through smoothly. It can effectively adjust the residence time of the rotor lamination in the hollow tube, so that it stays in the cleaning position for a certain period of time, ensuring that the cleaning fluid has sufficient contact with the surface of the lamination, and avoiding insufficient cleaning caused by too short a cleaning time or too fast slippage.

[0017] 3. The three swing arms driven by the drive gear contact the contact rollers on the rotating ring in sequence, causing the connecting frame, rotating ring and four porous tubes to swing at a certain angle, while compressing the arc springs. When the swing arms leave the contact rollers, the springs release their force and automatically return to their original positions, thereby realizing the reciprocating swing action of the porous tubes. This causes the spray angle of the cleaning fluid to change continuously during operation, which can increase the cleaning coverage area, thereby further reducing cleaning dead corners and improving cleaning uniformity and overall efficiency.

Detailed Implementation

[0034] The present invention will be further described in 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 Figures 1-7 As shown, the system includes a base frame 1, a cylinder 2 mounted on the base frame 1, a drain valve 3 connected to the bottom of the cylinder 2, two rotatable slip rings 4 on the base frame 1, four perforated pipes 5 evenly spaced between the two slip rings 4, and the drainage parts of the four perforated pipes 5 are all located inside the cylinder 2. A hollow pipe 6 is fixedly installed inside the cylinder 2, and several rotor laminations 61 are stacked on the upper part of the hollow pipe 6. An intermittent mechanism is provided on the base frame 1 and the hollow pipe 6 to intermittently control the feeding of the rotor laminations 61. A tensioning mechanism is provided on the hollow pipe 6 and the intermittent mechanism to tension the rotor laminations 61 that do not need to be fed. A lifting mechanism is provided on the base frame 1, the cylinder 2 and the hollow vertical shaft 71 to lift the cleaned rotor laminations 61.

[0036] The intermittent mechanism includes a hollow vertical shaft 71, which is rotatably mounted on a hollow tube 6. The lower end of the hollow vertical shaft 71 extends out of the bottom of the hollow tube 6. A servo motor 72 is mounted on the base frame 1. A drive gear 73 is mounted on the output shaft of the servo motor 72. A driven gear 74 is mounted on the lower end of the hollow vertical shaft 71. The drive gear 73 meshes with the driven gear 74. A slotted plate 75 is mounted on the hollow vertical shaft 71 and is located inside the hollow tube 6. Three baffles 76 for blocking the rotor laminations 61 are evenly spaced and slidably mounted on the upper part of the hollow tube 6. The three baffles 76 are in contact with one side of the bottom rotor lamination 61. A roller 77 is mounted on the side of the three baffles 76 that is close to each other. A drive groove is opened on the side of the slotted plate 75 that is close to the roller 77. The three rollers 77 are all located in the drive groove.

[0037] The tensioning mechanism includes support plates 81. Three support plates 81 are evenly spaced and slidably provided on the hollow tube 6 to support the rotor laminations 61. Each of the three support plates 81 is connected to a return spring 82 between it and the inner wall of the hollow tube 6. Each of the three support plates 81 is rotatably provided with a vertical roller 83 on the side that is close to each other. A concave column 84 is slidably provided on the upper part of the hollow vertical shaft 71. 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 simultaneously contact or detach from the three vertical rollers 83.

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

[0040] The material lifting mechanism includes a sliding pair 91. Two sliding pairs 91 are installed on the base frame 1. Each sliding pair 91 consists of a guide rail, a drive motor, a lead screw, and a slider. A slide 92 is installed between the sliders on the two sliding pairs 91. The slide 92 slides through the bottom of the cylinder 2. A push ring 93 for pushing out the rotor lamination 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 inside the hollow vertical shaft 71. The top end of the slide rod 94 is connected to the bottom of the concave column 84. 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 the movement of the slide.

[0041] First, the operator opens the drain valve 3 and introduces the cleaning fluid into the four perforated pipes 5 through the external inlet pipe. The cleaning fluid is sprayed from the perforated pipes 5 into the inside of the cylinder 2 and discharged through the drain valve 3, thus pre-cleaning the cylinder 2. Then, the operator places an appropriate number of rotor laminations 61 into the hollow tubes 6 in sequence. The bottom rotor lamination 61 contacts the three baffles 76, while the remaining rotor laminations 61 are held in place by the three support plates 81, but without interfering with the bottom rotor lamination 61. The operator then starts the servo motor 72. The output shaft of machine 72 drives the drive gear 73 to rotate, which in turn drives the driven gear 74, hollow vertical shaft 71, grooved disc 75, and concave column 84 to rotate synchronously. As the grooved disc 75 rotates, the three rollers 77 drive the three baffles 76 to move closer to each other. At the same time, the three grooves on the concave column 84 disengage from the vertical roller 83, thereby causing the concave column 84 to push the three vertical rollers 83 and their corresponding support plates 81 to move away from each other. When the three support plates 81 press against the upper rotor lamination 61, the three baffles 76 retract and retract. Inside the hollow tube 6; at this time, under the action of gravity, the bottom rotor lamination 61 slides down to the bottom of the cylinder 2 under the guidance of the hollow tube 6; the hollow vertical shaft 71, the slotted plate 75, and the concave column 84 continue to rotate, the three baffles 76 move outward and extend out of the hollow tube 6 again, while the support plate 81 resets inward with the cooperation of the vertical roller 83, releasing the support for the upper rotor lamination 61, so that all rotor laminations 61 move down as a whole; during this process, the bottom rotor lamination 61 re-contacts the three baffles 76; by intermittent feeding, only one at a time As the rotor laminations 61 fall, the porous tube 5 continuously sprays cleaning fluid to clean each individual rotor lamination 61, avoiding the impact of multiple laminations stacking on the cleaning effect. After cleaning, the rotor laminations 61 fall sequentially and are stacked on the push ring 93 located at the bottom of the cylinder 2. Waste fluid is discharged through the drain valve 3 to prevent the laminations from soaking for a long time. After all the rotor laminations 61 have been cleaned, the operator controls the rotation of the slotted plate 75 and the concave column 84 to the positioning state through the servo motor 72, so that the three baffles 76 are in the retracted state and the three support plates 81 are in the extended state.Then, two sliding joints 91 are activated, which drive the slide 92, push ring 93, and the cleaned and stacked rotor laminations 61 upward. After the slide 92 moves, it pushes the slide rod 94 and concave column 84 upward, and the vertical spring 85 is compressed accordingly. After the concave column 84 moves upward, it disengages from the three vertical rollers 83. Under the action of the return spring 82, the three support plates 81 move towards each other to reset, so that the cleaned and stacked rotor laminations 61 can be smoothly removed from the hollow tube 6. After the cleaned and stacked rotor laminations 61 are removed, the two sliding joints 91 drive the slide 92 and push ring 93 downward to reset. After the slide 92 moves, it disengages from the slide rod 94. Under the action of the vertical spring 85, the slide rod 94 and concave column 84 move downward to reset. The elastic force of the vertical spring 85 is greater than that of the return spring 82. The bottom of the arc-shaped concave column 84 contacts the arc surface of the three vertical rollers 83, causing the three support plates 81 to open again, preparing for the next cleaning.

[0042] Example 2: Based on Example 1, such as Figures 8-11 As shown, it also includes a blocking mechanism disposed on the hollow tube 6 and the hollow vertical shaft 71. The blocking mechanism is used to block the rotor laminations 61, so that the rotor laminations 61 can temporarily stop on the hollow tube 6. The blocking mechanism includes a crossbar 101. Six crossbars 101 are disposed inside the hollow tube 6. Three crossbars 101 located on the same horizontal plane form a group. Each crossbar 101 is rotatably provided with a swing plate 102. Three swing plates 102 located on the same horizontal plane form a group. The swing plates 102 are slidably embedded in the hollow tube 6. Three sliders 103 are slidably disposed inside the hollow tube 6. Each group of three sliders 103... Each of the three slide bars 102 has a semi-circular tooth 104 installed on the side closest to each other, and two vertical racks 105 are installed on the side far apart from each other. The six vertical racks 105 mesh with the six semi-circular teeth 104 respectively. Each of the three slide bars 103 has a horizontal roller 106 rotatably mounted on both the upper and lower parts. Two corrugated groove rings 107 are mounted on the hollow vertical shaft 71. Corrugated grooves are opened on the corrugated groove rings 107. 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 horizontal rollers 106 and the three slide bars 103 to move back and forth up and down. The three slide bars 103 drive the six vertical racks 105 to reciprocate, which in turn drives the six semi-arc teeth 104 and the six swing plates 102 to swing back and forth synchronously. When the swing plates 102 swing outward, they block the rotor laminations 61 from falling. When the swing plates 102 swing inward, they release the limit and allow the laminations to continue falling. Through two intermediate limit controls, the cleaning residence time of the rotor laminations 61 on the hollow tube 6 can be extended, thereby improving the cleaning effect.

[0044] Example 3: Based on Example 2, such as Figures 12-15 As shown, it also includes a reciprocating mechanism set on the cylinder 2, slip ring 4 and drive 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 slidably 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 swing rods 113 are evenly spaced on the drive gear 73. A contact roller 114 is rotatably provided on the rotating ring 111. During the rotation of the three swing rods 113, they 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] It also includes a pressure cap 12, which has three protrusions. The hollow tube 6 has three guide holes 13 at the top. The pressure cap 12 is detachably slidably inserted into the guide holes 13 through the three protrusions.

[0046] During the cleaning process, the rotation of the drive gear 73 also drives the three swing rods 113 to rotate synchronously. When the swing rods 113 contact the contact rollers 114 on the rotating ring 111 in sequence, 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 spring 115 is compressed. After the swing rods 113 disengage from the contact rollers 114, the arc spring 115 releases its 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 cleaning fluid spray angle, thereby improving the uniformity and efficiency of cleaning.

[0047] When placing the rotor laminations 61, the operator first removes the pressure cover 12 and places several rotor laminations 61 into the hollow tube 6 in sequence, so that the bottom rotor lamination 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 laminations 61 are pressed together under their own weight, so that the bottom lamination is always in close contact with the baffles 76, thus avoiding insufficient pressure due to a reduction in the number of rotor laminations 61, which would affect the intermittent control effect.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
