Description

Technical Field

[0001] The invention belongs to the technical field of motor housing spraying, and in particular relates to a high-efficiency spraying device for a stepper motor housing. Background Art

[0002] During the manufacturing process of the motor housing, since the motor housing is susceptible to oxidation, corrosion and rust, it is necessary to spray paint on the motor housing to form a protective layer on the outer surface of the motor housing to block external moisture, chemicals and oxygen, reduce the exposure of the outer surface of the motor housing, and thus extend the service life of the motor housing.

[0003] The prior art discloses some invention patents in the field of motor housing spraying technology, among which the invention patent with publication number CN118988621A discloses a motor housing processing spraying device, including a spraying equipment body, a driving base is installed on the bottom surface of the spraying equipment body, and a placing mechanism is installed on the top of the driving base, and a limiting mechanism is installed below the end of the placing mechanism. This technical solution can conveniently move the motor housing placed on the surface of the placing seat into the drying frame by driving the rotation of the turntable, and the outside air can be drawn into the heating chamber for heating by the blower, and the heated air is blown into the drying frame by the guidance of the diversion air duct and the air outlet, so that the motor housing after spraying inside the drying frame can be dried conveniently, and the sagging of the motor housing after spraying can be effectively avoided. It affects the finished product effect after the motor housing is sprayed. At the same time, by connecting the air duct, the hot air inside the diversion air duct can be diverted and guided into the exhaust duct, so that the exhaust duct can blow the hot air down above the drying frame, effectively improving the drying effect inside the drying frame. This technical solution still has some shortcomings in the application process. Although it is considered that the stepper motor housing has just been transferred to the drying equipment after spraying, it is easy to cause the paint surface to sag due to the fluidity of the paint surface, but the effect of hot air on the paint surface is not taken into account. Directly using hot air for drying may cause the volatilization rate of the coating surface to accelerate, causing the paint film surface to dry too quickly, while the bottom layer is still not dry, resulting in uneven drying, and volatile organic compounds and waste liquids may be generated during the drying process, causing pollution to the environment and emitting substances harmful to the human body.

[0004] Based on this, the present invention designs a high-efficiency spraying device for a stepper motor housing to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that although the prior art takes into account that the stepper motor casing is easily prone to sag due to the fluidity of the paint surface after it is transferred to the drying equipment after spraying, it does not take into account the influence of hot air on the paint surface.

[0025] 1. In the present invention, the hot air entering the outer cover flows toward the newly sprayed casing body, and multiple casing bodies are dried simultaneously inside the outer cover, and the wind force and temperature are higher closer to the wind cover. Since the motor is still in operation after the casing body enters the outer cover, the casing body continues to rotate, so that the hot air contacts each surface of the casing body more evenly, which is conducive to a comprehensive and relatively uniform drying process for the casing body. After passing through multiple casing bodies, the hot air acts on the casing body that enters the outer cover last, and the hot air temperature there is The temperature is the lowest and the wind force is the weakest, which is not enough to blow the outer and inner plugging components at this location, so that the surface drying rate of the paint surface of the casing body is low, which can effectively avoid the unfavorable situation that the surface of the paint film dries too quickly while the bottom layer is still not dry, so that the paint film dries more evenly, and the exhaust pipe is connected to the rear end of the outer cover to discharge the hot air at the casing body that finally enters the outer cover. During the drying process, since the interior of the outer cover is a closed structure, the odor of the paint during drying is prevented from polluting the surrounding air, and the odor emitted by the paint during the drying process is prevented from causing harm to the human body.

[0026] 2. In the present invention, the closer to the wind hood, the higher the opening degree of the two docking blocking plates. Conversely, the two blocking plates farthest from the wind hood cannot be opened due to the weakening of wind force. The two blocking plates are highly opened to form a large air outlet, and the two blocking plates are less opened to form a small air outlet. The largest large air outlet is used to dry the last side of the casing body. The large air outlet has a larger blowing area, which can accelerate the evaporation of moisture in the paint film, thereby shortening the drying time. The smallest small air outlet is used to dry the casing body that has just entered the outer cover. The wind speed of the small air outlet is relatively slow, which is conducive to the gradual evaporation of moisture inside the paint film, thereby achieving more uniform drying. The increments of multiple air outlets are decreasing, which can further improve the drying uniformity and improve the drying efficiency to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please see attached Figure 1 -Attached Figure 8The present invention provides a technical solution: a high-efficiency spraying device for a stepper motor 309 housing, comprising a spraying cabinet 1 and a mechanical arm 10 connected to the top of the spraying cabinet 1 for spraying the stepper motor 309 housing, an outer transfer interface 2 is provided on the spraying cabinet 1, and a self-rotation component 3 for driving multiple stepper motor 309 housings to rotate simultaneously is rotatably connected in the outer transfer interface 2, an inner transfer interface 5 is provided on the spraying cabinet 1 corresponding to the inner side of the outer transfer interface 2, and a rotary switching component 6 connected to the self-rotation component 3 is rotatably connected in the inner transfer interface 5, and is used to drive multiple stepper motor 309 housings to make circular motions, and a railing frame 4 for supporting is connected to the inner top of the spraying cabinet 1;

[0039] The rotation component 3 is connected to a drying component 9 for drying the paint surface of the stepper motor 309 casing. The rotation component 3 is connected to a plurality of outer sealing components 7 in a circular array. The rotation component 3 is connected to a plurality of inner sealing components 8 corresponding to the plurality of outer sealing components 7. The plurality of groups of outer sealing components 7 and inner sealing components 8 are used for segmenting the interior of the drying component 9.

[0040] Specifically, the self-rotating assembly 3 includes an outer ring body 301 rotatably connected to the outer transfer port 2, an annular table 302 is connected to the outer ring body 301, and a plurality of first transfer shafts 303 in an annular array are rotatably connected to the outer ring body 301 and the annular table 302, an end of the first transfer shaft 303 is connected to a housing frame 304, a housing body 305 is placed on the housing frame 304, and the other end of the first transfer shaft 303 is connected to a first driven gear 306, and a double tooth surface ring 310 is meshed on the outer periphery of the tooth surface of the first driven gear 306;

[0041] The outer ring tooth surface of the double-tooth surface ring 310 is meshed with a driving gear 307 , and a motor shaft 308 is sleeved inside the driving gear 307 . A motor 309 is installed at the other end of the motor shaft 308 , and the motor 309 is installed inside the spray booth 1 .

[0042] The specific implementation method is as follows: a manipulator is installed at a gap in the outer cover 901 corresponding to one side of the spray cabinet 1, and the manipulator is first controlled to place the housing body 305 to be sprayed on the adjacent housing frame 304, and then the motor 309 is controlled to operate. The motor 309 drives the driving gear 307 to rotate through the motor shaft 308, and the double-toothed surface ring 310 performs a circular motion in the slide groove through the slip ring under the drive of the driving gear 307. During this process, the double-toothed surface ring 310 cooperates with multiple first driven gears 306 to drive multiple first transfer shafts 303 to rotate at the same time. The rotation of the first transfer shaft 303 will drive the housing body 305 swinging thereon to rotate through the moving wheel frame 6045. During the stable rotation of the housing body 305, the manipulator 10 is controlled to perform a spraying operation on it.

[0043] Specifically, a slide groove is provided at the top of the inner side of the spray booth 1, and a slip ring connected to the double tooth surface ring 310 is slidably connected in the slide groove. The cross-sectional shape of the slip ring and the slide groove is T-shaped when viewed from the side. The cross-sectional shape of the outer transfer interface 2 and the inner transfer interface 5 when viewed from the side is cross-shaped. The rotary switching component 6 includes an inner gear ring 601 rotatably connected to the inner transfer interface 5, and the tooth surface of the inner gear ring 601 is meshed with a second driven gear 603. The inner side of the second driven gear 603 is sleeved with a second transfer shaft 602 rotatably connected to the inner top of the spray booth 1, and the other end of the second transfer shaft 602 is sleeved with a transmission member 604, and the transmission member 604 includes a sleeve on the second transfer shaft A first driven pulley 6041 is on the connecting shaft 602, and a driving pulley 6042 is mounted on the motor shaft 308 corresponding to the first driven pulley 6041. A second driven pulley 6043 is arranged on one side of the driving pulley 6042. The second driven pulley 6043, the driving pulley 6042 and the first driven pulley 6041 are sleeved with a same transmission belt 6044. The second driven pulley 6043 is rotatably connected to a driven wheel frame 6045. A hydraulic cylinder 605 is installed on the top of the spray cabinet 1. The telescopic end of the hydraulic cylinder 605 is connected to the driven wheel frame 6045, and the telescopic end of the hydraulic cylinder 605 is controlled to adjust the tightness of the transmission belt 6044.

[0044] The specific implementation method is as follows: after the single housing body 305 completes the spraying operation, the hydraulic cylinder 605 is controlled to retract, and the hydraulic cylinder 605 drives the second driven pulley 6043 to move away from the first driven pulley 6041 and the driving pulley 6042 through the driven pulley frame 6045. As the second driven pulley 6043 moves, the transmission belt 6044 is gradually tightened from a loose state, and the friction between the transmission belt 6044 and the first driven pulley 6041, the second driven pulley 6043 and the driving pulley 6042 increases. Since the motor shaft 308 will also drive the driving pulley 6042 to rotate during the rotation process, the active drive will be driven by the transmission belt 6044 drives the first driven pulley 6041 and the second driven pulley 6043 to rotate. During the rotation process, the second driven pulley 6043 drives the second driven gear 603 to rotate through the second adapter shaft 602. The second driven gear 603 drives the inner gear ring 601 to rotate in the inner adapter interface 5. Since the inner gear ring 601 is connected to the annular table 302, it can drive the annular table 302 to rotate in the clockwise direction. The rotation of the annular table 302 drives the casing body 305 above it that completes the spraying operation to make a circular motion until a group of outer sealing components 7 and inner sealing components 8 behind the casing body 305 enter the outer cover 901 together.

[0045] Specifically, the drying component 9 includes an outer cover 901 covering the outer periphery of the annular table 302, the outer cover 901 is connected to the top of the spray cabinet 1, the circumferential surface of the outer cover 901 is connected to a wind hood 904, the back of the wind hood 904 is connected to an air supply pipe 902, a hot air blower 903 is installed inside the spray cabinet 1, and the other end of the air supply pipe 902 is connected to the hot air blower 903.

[0046] The specific implementation method is as follows: after the newly-painted casing body 305 and a group of outer plugging components 7 and inner plugging components 8 at the rear enter the outer cover 901 together, the hot air blower 903 is controlled to operate, and the hot air generated by the hot air blower 903 is sent into the wind hood 904 through the air supply pipe 902. The hot air enters the outer cover 901 after being diverted in the wind hood 904. The hot air entering the outer cover 901 flows toward the newly-painted casing body 305, and multiple casing bodies 305 are dried at the same time inside the outer cover 901, and the closer to the wind hood 904, the higher the wind force and temperature. Since the motor 309 is still in operation after the casing body 305 enters the outer cover 901, the casing body 305 continues to rotate, so that the contact effect between the hot air and each surface of the casing body 305 is more uniform.

[0047] Specifically, the outer sealing component 7 and the inner sealing component 8 have the same structure. The outer sealing component 7 includes a transfer box 701 connected to the top of the annular table 302. The inner side of the transfer box 701 is rotatably connected to a third transfer shaft 702. A groove 703 is provided at the end of the third transfer shaft 702. A fourth transfer shaft 704 is connected to the inner bottom of the groove 703. The third transfer shaft 702 is rotatably connected to the transfer box 701 via the fourth transfer shaft 704. A transfer spring 705 is sleeved on the fourth transfer shaft 704. The fourth transfer shaft 704 is elastically transferred to the transfer box 701 via the transfer spring 705. A sealing plate 707 is connected to the fourth transfer shaft 704. A limiting plate 706 for limiting the sealing plate 707 is connected to the transfer box 701.

[0048] The specific implementation method is as follows: when the outer sealing component 7 and the inner sealing component 8 entering the outer cover 901 are affected by hot air, the sealing plate 707 rotates on the inner side of the adapter box 701 by using the third adapter shaft 702 through the fourth adapter shaft 704, and the two sealing plates 707 are opened, and the closer to the wind cover 904, the higher the opening degree of the two docked sealing plates 707. On the contrary, the two sealing plates 707 farthest from the wind cover 904 cannot be opened due to the weakening of wind force. The two sealing plates 707 are opened to a high degree to form a large air outlet, and the two sealing plates 707 are opened to a low degree to form a small air outlet. The largest large air outlet is used to dry the last side of the casing body 305. The large air outlet has a large blowing area, which can accelerate the evaporation of moisture in the paint film, thereby shortening the drying time. The smallest small air outlet is used to dry the casing body 305 that has just entered the outer cover 901. The wind speed of the small air outlet is relatively slow, which is conducive to the gradual evaporation of moisture inside the paint film.

[0049] Working principle, when using:

[0050] A manipulator is installed at the notch of the outer cover 901 corresponding to one side of the spray booth 1. The manipulator is first controlled to place the housing body 305 to be sprayed on the adjacent housing frame 304, and then the motor 309 is controlled to operate. The motor 309 drives the driving gear 307 to rotate through the motor shaft 308. Driven by the driving gear 307, the double-toothed surface ring 310 performs a circular motion in the slide groove through the slip ring. During this process, the double-toothed surface ring 310 cooperates with the multiple first driven gears 306 to simultaneously drive the multiple first transfer shafts 303 to rotate. The rotation of the first transfer shaft 303 will drive the housing body 305 swinging thereon to rotate through the moving wheel frame 6045. During the stable rotation of the housing body 305, the manipulator 10 is controlled to perform a spraying operation on it.

[0051] After the single housing body 305 completes the spraying operation, the hydraulic cylinder 605 is controlled to retract, and the hydraulic cylinder 605 drives the second driven pulley 6043 to move away from the first driven pulley 6041 and the driving pulley 6042 through the driven pulley frame 6045. As the second driven pulley 6043 moves, the transmission belt 6044 is gradually tightened from a loose state, and the friction between the transmission belt 6044 and the first driven pulley 6041, the second driven pulley 6043 and the driving pulley 6042 increases. Since the motor shaft 308 will also drive the driving pulley 6042 to rotate during the rotation process, the active drive will be driven by the transmission belt 6044. The first driven pulley 6041 and the second driven pulley 6043 are driven to rotate. During the rotation process, the second driven pulley 6043 is driven by the second transfer shaft 602 to rotate the second driven gear 603. The second driven gear 603 is used to drive the inner gear ring 601 to rotate in the inner transfer interface 5. Since the inner gear ring 601 is connected to the annular table 302, it can drive the annular table 302 to rotate in the clockwise direction. The rotation of the annular table 302 drives the casing body 305 above it that has completed the spraying operation to make a circular motion until a group of outer plugging components 7 and inner plugging components 8 behind the casing body 305 enter the outer cover 901 together.

[0052] After the newly painted casing body 305 and a group of outer plugging components 7 and inner plugging components 8 at the rear enter the outer cover 901 together, the hot air blower 903 is controlled to operate, and the hot air generated by the hot air blower 903 is sent into the wind cover 904 through the air supply pipe 902. The hot air is diverted in the wind cover 904 and then enters the outer cover 901. The hot air entering the outer cover 901 flows toward the newly painted casing body 305, and multiple casing bodies 305 are dried simultaneously inside the outer cover 901, and the closer to the wind cover 904, the higher the wind force and temperature. Since the motor 309 is still in operation after the casing body 305 enters the outer cover 901, the casing body 305 continues to rotate, so that the contact effect between the hot air and each surface of the casing body 305 is more uniform, which is beneficial to the casing body. The body 305 is subjected to a comprehensive and relatively uniform drying treatment. After passing through multiple casing bodies 305, the hot air acts on the casing body 305 that finally enters the outer cover 901. The hot air temperature at this location is the lowest and the wind force is the weakest, which is insufficient to blow the outer sealing component 7 and the inner sealing component 8 at this location, so that the surface drying rate of the paint surface of the casing body 305 is low, which can effectively avoid the unfavorable situation that the surface of the paint film dries too quickly while the bottom layer is still not dry, so that the paint film dries more evenly. The exhaust pipe is connected to the rear end of the outer cover 901 to discharge the hot air at the casing body 305 that finally enters the outer cover 901. During the drying process, since the interior of the outer cover 901 is a closed structure, the odor of the paint during drying is prevented from polluting the surrounding air, and the odor emitted by the paint during the drying process is prevented from causing harm to the human body.

[0053] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
