Description

Technical Field

[0001] This utility model belongs to the field of inter-turn insulation, and specifically relates to a steel plate loading and unloading device for producing rotor inter-turn insulation. Background Technology

[0002] Rotor turn-to-turn insulation is produced by vacuum hot-pressing epoxy fiberglass cloth and stainless steel plate, followed by slitting. This rotor turn-to-turn insulation exhibits excellent electrical insulation, mechanical properties, and heat resistance. During installation, a layer of epoxy fiberglass cloth is first laid manually, followed by a stainless steel plate, then another layer of epoxy fiberglass cloth is placed on top. An insulating film is then placed on top of the upper epoxy fiberglass cloth layer, and the epoxy fiberglass cloth and stainless steel plate are laid in the same order. After multiple layers are laid, the entire assembly is placed in an autoclave for vacuum hot-pressing and curing. Finally, it is slitted to form the rotor turn-to-turn insulation.

[0003] During the laying process of stainless steel and epoxy fiberglass cloth, oil, moisture, and impurities on the surface of the stainless steel plate can hinder the tight bonding between the epoxy fiberglass cloth and the stainless steel plate, leading to a decrease in the hot pressing effect, the generation of air bubbles and voids, and a reduction in the interfacial bonding strength between the stainless steel plate and the epoxy fiberglass cloth. Therefore, it is necessary to wipe the surface of the stainless steel plate to remove oil, moisture, dust, and impurities. Currently, the operation requires wiping the upper surface of the stainless steel plate, manually handling the wiped stainless steel plate, and turning it over so that the wiped surface comes into contact with the epoxy fiberglass cloth. Then, the upper surface of the stainless steel plate is wiped again, and another layer of epoxy fiberglass cloth is laid. Therefore, each set of laying requires manual double-sided wiping, interspersed with the turning operation of the stainless steel plate, which is inefficient and cannot meet the needs of large-scale production. Secondly, when turning over, the operator comes into contact with the stainless steel plate, and the cleaned parts are still at risk of being contaminated, leading to secondary contamination. Due to the large length of the stainless steel plate, the edges of the stainless steel plate are prone to collision and wear during the turning process. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a steel plate loading and unloading device for producing rotor inter-turn insulation, which realizes double-layer cleaning of stainless steel plates without flipping them over, avoids secondary pollution caused by manual operation, and ensures the cleaning effect and surface quality of stainless steel plates.

[0005] The objective of this utility model is achieved through the following technical solution: a steel plate loading and unloading device for producing rotor inter-turn insulation, comprising... A movable crossbeam assembly includes a movable crossbeam and fixed rails placed on both sides above the movable crossbeam. A trolley is located between the two fixed rails. The trolley and the movable crossbeam are arranged vertically and vertically, and a lifting hoist is located between the trolley and the movable crossbeam. A loading and unloading suction cup assembly includes multiple suction cups disposed on the lower end face of a moving crossbeam. The multiple suction cups are evenly distributed along the extension direction of the moving crossbeam. The end of the moving crossbeam has a suction pump that is connected to the multiple suction cups respectively through an air pipe. An impurity wiping assembly is provided, which is located at the end of the moving crossbeam and moves along the extension direction of the moving crossbeam to achieve double-sided wiping of the stainless steel plate.

[0006] A further improvement of this utility model is that when the loading and unloading suction cup assembly adsorbs the stainless steel plate, the impurity wiping assembly slides on the moving crossbeam and wipes the lower end surface of the stainless steel plate; when the loading and unloading suction cup assembly separates from the stainless steel plate, the impurity wiping assembly slides on the moving crossbeam and wipes the upper end surface of the stainless steel plate.

[0007] A further improvement of this utility model is that: the impurity wiping assembly includes a housing disposed on the upper end face of the moving crossbeam, the housing has a slide rail and a slider placed in the slide rail, the slide rail has fixed seats at both axial ends, a lead screw passes through the fixed seats and the slider, the lead screw is threadedly connected to the slider, and a reduction motor for driving the lead screw to rotate is on a fixed seat. The slider has horizontal plates on both sides facing outwards. The housing has sliding holes on both sides for the horizontal plates to pass through and slide. The ends of the horizontal plates extend vertically towards the stainless steel plate. There are two corresponding connecting rods between the two vertical plates, and wiping cotton is sleeved on both connecting rods.

[0008] A further improvement of this utility model is that the two ends of the connecting rod are detachably connected to the vertical plate by bolts.

[0009] A further improvement of this utility model is that: the side end of the movable crossbeam has a through hole communicating with the corresponding air pipe, and the side end face of the movable crossbeam has a groove for the air pipe to be embedded laterally.

[0010] A further improvement of this utility model is that: the stainless steel plate is placed on the support platform, the axial length of the moving crossbeam is greater than the axial length of the support platform, and the two ends of the moving crossbeam are placed on the outer side of the end of the stainless steel plate.

[0011] A further improvement of this utility model is that the width of the wiping cotton is greater than the radial width of the stainless steel plate.

[0012] A further improvement of this utility model is that the number of lifting hoists is 2-3, and the bottom of the lifting hoist is fixedly connected to the upper end face of the shell.

[0013] This utility model has the following advantages compared with the prior art: 1. Compared with traditional manual cleaning, flipping, and handling of stainless steel plates, this utility model effectively achieves non-contact cleaning and step-by-step cleaning by using a suction cup assembly for adsorption and fixation of the stainless steel plate and an impurity wiping assembly for wiping and cleaning the front and back of the stainless steel plate. This avoids secondary pollution and collision wear during the manual flipping process, and realizes an automated process of stainless steel plate adsorption, handling, wiping, layering, and re-wiping, ensuring the cleaning effect and surface quality of the stainless steel plate, and improving the overall quality and stability of the rotor inter-turn insulation.

[0014] 2. In this utility model, after the upper surface of the stainless steel plate is adsorbed by the loading and unloading suction cup assembly, the impurity wiping assembly places the wiping cotton on the lower end surface of the stainless steel plate and cleans it. When the loading and unloading suction cup assembly moves the stainless steel plate with the lower end surface wiped to the upper end of the epoxy fiberglass cloth, the loading and unloading suction cup assembly releases the stainless steel plate. The impurity wiping assembly then places the wiping cotton on the upper end surface of the stainless steel plate and wipes it, thereby completing the double-sided wiping and cleaning of the stainless steel plate. Throughout the process, there is no need for manual flipping of the stainless steel plate, completely eliminating the risk of secondary pollution. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this utility model according to the specific circumstances.

[0023] A steel plate loading and unloading device for producing rotor inter-turn insulation, as described in the reference. Figure 1 ,include A movable crossbeam assembly 1, comprising a movable crossbeam 11 and fixed rails 12 placed on both sides above the movable crossbeam 11, with a trolley 13 between the two fixed rails 12, the trolley 13 being vertically and vertically corresponding to the movable crossbeam 11, and a lifting hoist 14 between the trolley 13 and the movable crossbeam 11. A loading and unloading suction cup group 2 includes multiple suction cups 21 disposed on the lower end face of the moving crossbeam 11. The multiple suction cups 21 are evenly distributed along the extension direction of the moving crossbeam 11. The end of the moving crossbeam 11 has a suction pump 22 that is connected to the multiple suction cups 21 respectively through an air pipe 23. An impurity wiping group 3 is provided at the end of the moving crossbeam 11 and moves along the extension direction of the moving crossbeam 11, thereby achieving double-sided wiping of the stainless steel plate 4.

[0024] Compared to traditional manual cleaning, flipping, and handling of stainless steel plates, this utility model effectively achieves non-contact and step-by-step cleaning by using the suction cup group 2 to adsorb and fix the stainless steel plate 4 and the impurity wiping group 3 to wipe the front and back of the stainless steel plate 4. This avoids secondary pollution and collision wear during the manual flipping process, and realizes an automated process of adsorption, handling, wiping, layering, and re-wiping of the stainless steel plate 4, ensuring the cleaning effect and surface quality of the stainless steel plate 4, and improving the overall quality and stability of the rotor inter-turn insulation.

[0025] When the loading and unloading suction cup group 2 picks up the stainless steel plate 4, the impurity wiping group 3 slides on the moving crossbeam 11 and wipes the lower end surface of the stainless steel plate 4. When the loading and unloading suction cup group 2 separates from the stainless steel plate 4, the impurity wiping group 3 slides on the moving crossbeam 11 and wipes the upper end surface of the stainless steel plate 4.

[0026] Reference Figures 2 to 4 The impurity wiping assembly 3 includes a housing 310 disposed on the upper end face of the movable crossbeam 11. The housing 310 has a slide rail 31 and a slider 32 disposed in the slide rail 31. The slide rail 31 has fixed seats 33 at both axial ends. A lead screw 34 passes through the fixed seat 33 and the slider 32. The lead screw 34 is threadedly connected to the slider 32. A reduction motor 35 that drives the lead screw 34 to rotate is provided on a fixed seat 33. The slider 32 has horizontal plates 36 on both sides facing outwards. The housing 310 has sliding holes 311 on both sides for the horizontal plates 36 to pass through and slide. The ends of the horizontal plates 36 extend vertically toward the stainless steel plate 4 with vertical plates 37. There are two corresponding connecting rods 38 between the vertical plates 37 on both sides. The two connecting rods 38 are fitted with wiping cotton 39.

[0027] In this invention, after the upper surface of the stainless steel plate 4 is adsorbed by the loading and unloading suction cup group 2, the impurity wiping group 3 places the wiping cotton 39 on the lower end surface of the stainless steel plate 4 and cleans it. When the loading and unloading suction cup group 2 moves the stainless steel plate 4, which has been wiped on the lower end surface, to the upper end of the epoxy fiberglass cloth, the loading and unloading suction cup group 2 releases the stainless steel plate 4. The impurity wiping group 3 then places the wiping cotton on the upper end surface of the stainless steel plate 4 and wipes it, thereby completing the double-sided wiping and cleaning of the stainless steel plate 4. Throughout the process, there is no need for manual flipping of the stainless steel plate, completely eliminating the risk of secondary pollution.

[0028] When the geared motor 35 starts, it drives the lead screw 34 to perform threaded transmission with the slider 32, thereby causing the slider 32 to slide on the corresponding slide rail 31. This causes the wiping cotton 39 on the impurity wiping group 3 to come into contact with the end face of the stainless steel plate 4 for cleaning. When the loading and unloading suction cup group 2 is fixed to the stainless steel plate 4, the wiping cotton 39 is placed on the lower end face of the stainless steel plate 4 and moves along its axial direction. The two vertical plates 37 are placed on the outer end face of the stainless steel plate 4. When the loading and unloading suction cup group 2 releases the stainless steel plate 4, the stainless steel plate 4 is placed on the upper end face of the epoxy fiberglass cloth. At this time, the wiping cotton 39 is placed on the upper end face of the stainless steel plate 4 and moves along its axial direction.

[0029] Based on this embodiment, the two ends of the connecting rod 38 are detachably connected to the vertical plate 37 by bolts. After the wiping cotton 39 has been used multiple times, the bolts can be removed, and the connecting rod 38 and the wiping cotton 39 can be removed as a whole. The wiping cotton 39 can then be taken off the connecting rod 38. The wiping cotton 39 is then placed on the two connecting rods 38 to achieve horizontal positioning support for the wiping cotton 39.

[0030] Based on this embodiment, the side end of the movable crossbeam 11 has a through hole 25 that communicates with the corresponding air pipe 23, and the side end face of the movable crossbeam 11 has a groove 24 for the air pipe 23 to be embedded laterally.

[0031] This utility model achieves a concealed layout and efficient connection of the air pipe 23 by setting through holes 25 and grooves 24 on the side of the movable crossbeam 11. The air pipe 23 is embedded in the groove 24, protecting the air pipe from external interference and reducing the risk of wear.

[0032] Based on this embodiment, the stainless steel plate 4 is placed on the support platform 5, the axial length of the moving crossbeam 11 is greater than the axial length of the support platform 5, and the two ends of the moving crossbeam 11 are placed on the outside of the ends of the stainless steel plate 4. This design forms a full-coverage working range, ensuring that the loading and unloading suction cup group 2 at the end of the moving crossbeam 11 accurately adsorbs the edge area of ​​the plate, eliminating blind spots in cleaning or layering. The extra-long moving crossbeam 11 disperses the force on the crossbeam and reserves space for the impurity wiping group 3 to be operated, which facilitates the loading and unloading of the stainless steel plate 4 and double-sided cleaning.

[0033] Based on this embodiment, the width of the wiping cotton 39 is greater than the radial width of the stainless steel plate 4, thereby expanding the radial wiping range of the wiping cotton 39 on the stainless steel plate 4, ensuring that the area from the edge to the center of the stainless steel plate 4 is effectively cleaned, avoiding omissions, and achieving full-coverage cleaning.

[0034] Based on this embodiment, the number of lifting hoists 14 is 2-3, and the bottom of the lifting hoist 14 is fixedly connected to the upper end face of the housing 310.

[0035] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
