Description

Technical Field

[0001] The invention relates to the technical field of transformer core cleaning, and in particular to a transformer core cleaning device. Background Art

[0002] The transformer core is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint. If there is dust and impurities on the surface of the silicon steel sheet, it may increase the magnetic resistance, reduce the electromagnetic performance of the core, or destroy the insulation layer between the silicon steel sheets, causing a short circuit inside the core, accelerating the corrosion and aging of the silicon steel sheets, and shortening the service life of the transformer. Therefore, the silicon steel sheets of the transformer core need to be cleaned before stacking to ensure that there is no dust, oil or other impurities on the surface of the core.

[0003] A Chinese patent with announcement number CN215613611U discloses a cleaning device for a transformer core, comprising a cleaning box, wherein the cleaning box is provided with a cleaning assembly, wherein the cleaning assembly comprises a card interface, wherein two of the card interfaces are symmetrically arranged on the sides of the cleaning box, wherein a sliding block is slidably installed inside the card interface, wherein a hexagonal shaft is rotatably installed in the middle of the sliding block, wherein end frames are welded to both ends of the hexagonal shaft, and a card-jointing frame is evenly distributed on the outside between the two end frames, wherein rubber clip strips are bonded to the inner walls on both sides of the card-jointing frame, wherein a support ring is slidably installed between a plurality of the card-jointing frames, and wherein side strips are welded to the outside of the support ring corresponding to the rubber clip strips.

[0004] The above patent clamps the silicon steel sheets constituting the iron core between the rubber clips in sequence, and then drives the rubber clips on the outside of the hexagonal shaft to rotate through a motor, so that the silicon steel sheets are constantly in contact and collide with the cleaning liquid in the cleaning box to complete the cleaning.

[0005] However, in the actual implementation process, the above patent requires manual clamping of the silicon steel sheet between the rubber clips. Since the silicon steel sheet is usually thin, adjacent silicon steel sheets may be adsorbed and bonded together. Therefore, it is more labor-intensive to take a single silicon steel sheet, and the silicon steel sheet is thin, which may scratch the staff during installation. In addition, when the silicon steel sheet needs to be removed after cleaning, the above patent requires the hexagonal shaft and the end frame to be taken out together, and then the support ring is pulled to squeeze the rubber clips on the side strips to cancel the clamping of the silicon steel sheet, and the silicon steel sheet falls under the action of gravity. Removing the hexagonal shaft and the end frame requires a lot of manpower, and the removal and installation process is cumbersome, which affects the cleaning efficiency. In addition, the silicon steel sheet falls by its own weight, which may cause the silicon steel sheet to collide and be damaged, affecting the normal use of the silicon steel sheet.

[0006] Therefore, the art needs a transformer core cleaning device to solve the above problems. Summary of the invention

[0007] The present invention provides a cleaning device for a transformer core, aiming to solve the problems in the related art that the cleaning device requires much manual participation, resulting in low cleaning efficiency, difficulty in separating stacked silicon steel sheets when installing them, easily causing scratches to workers, and easy collision and damage to the silicon steel sheets when the cleaned silicon steel sheets are removed.

[0008] A cleaning device for a transformer core of the present invention comprises a machine body and a conveying assembly arranged on the machine body, the conveying assembly comprises a conveyor belt and a driving assembly 1 for driving the conveyor belt to rotate, a material storage box located below the conveyor belt is arranged on the machine body, a pushing assembly for pushing upward a silicon steel plate of the transformer core is arranged at the bottom of the material storage box, suction cups are arranged at intervals on the conveyor belt, and the suction cups are connected to a driving assembly 2 for driving them to adsorb the silicon steel plate; A wiping assembly 1 is provided below the conveyor belt, and a wiping assembly 2 is provided above the conveyor belt. The wiping assembly 1 includes a wiping belt and a driving assembly 3 for driving the wiping belt to rotate. The rotation direction of the wiping belt is the same as that of the conveyor belt. When the suction cup rotates to the bottom of the conveyor belt, the driving assembly 2 drives the suction cup to absorb the silicon steel plate in the storage box. As the conveyor belt rotates, the silicon steel plate passes above the wiping belt, and the wiping belt wipes the first surface of the silicon steel plate. The second wiping component includes a wiping plate fixedly connected to the machine body, and a guide groove for the suction cup to pass through is opened on the wiping plate. When the suction cup drives the silicon steel plate to rotate above the conveyor belt, the wiping plate wipes the second surface of the silicon steel plate.

[0009] The present invention automatically absorbs the silicon steel plate through the suction cup, and wipes the two sides of the silicon steel plate through the wiping component one and the wiping component two during the conveying process of the conveyor belt, thereby realizing automatic cleaning of the silicon steel plate, improving the cleaning efficiency, reducing manual participation, and reducing the probability of the silicon steel plate causing scratches to the staff; The silicon steel plate is transported by a conveyor belt and a suction cup. When the cleaning is completed and the plate is unloaded, the suction cup is controlled to cancel the adsorption of the silicon steel plate, and the silicon steel plate is lifted away or transported away by a conveyor belt. The silicon steel plate will not be damaged by collision, and the quality of the silicon steel plate is guaranteed. In addition, since silicon steel plates are usually thin, adjacent silicon steel plates may be adsorbed and bonded together. When the suction cup grabs the top silicon steel plate, two multi-piece silicon steel plates may be taken away. When the suction cup drives the silicon steel plate to move onto the wiping belt, since the wiping belt and the silicon steel plate move in opposite directions, the other silicon steel plates adhered to the bottom of the silicon steel plate will be rubbed, so that the adhered silicon steel plate is separated from the silicon steel plate adsorbed by the suction cup, and the adhered silicon steel plate is pushed back to the top of the storage box, which solves the problem that the stacked silicon steel sheets are difficult to separate, resulting in the stacked surface being unable to be wiped.

[0010] Preferably, the conveying direction of the conveyor belt is defined as left and right direction, the suction cup is elastically connected to the conveyor belt along the front-to-back direction through an elastic member, the guide groove is provided with an inclined section, and the machine body is fixedly connected with a pushing block corresponding to the inclined section, and when the guide groove guides the suction cup to move along the inclined section, the elastic member is subjected to force, and the pushing block blocks the silicon steel plate adsorbed by the suction cup from following the movement of the suction cup, and the suction cup moves relative to the corresponding silicon steel plate, so that the wiping plate wipes the position on the silicon steel plate originally covered by the suction cup.

[0011] Through the cooperation of the inclined section of the guide groove and the push block, the relative movement between the suction cup and the silicon steel plate is achieved, and the original adsorption position of the suction cup on the silicon steel plate is exposed, so that the wiping plate can wipe the part originally covered by the suction cup, so as to achieve the effect of comprehensive cleaning of both sides of the silicon steel plate.

[0012] Preferably, the wiping plate is provided with an ascending section, and the guide groove is provided with a contraction section corresponding to the position of the ascending section, the contraction section squeezes the suction cup to cancel the adsorption of the silicon steel plate, and the ascending section guides the silicon steel plate to move away from the suction cup so that the suction cup and the silicon steel plate are out of contact.

[0013] The rising section of the wiping plate will lift the silicon steel plate upward, and the contraction section of the guide groove will squeeze the two sides of the suction cup, so that air enters between the suction cup and the silicon steel plate, thereby achieving the effect of rapid separation of the suction cup and the silicon steel plate.

[0014] Preferably, the conveyor belt is provided with a slide groove extending in the front-to-back direction, a slider is slidably connected in the slide groove, the elastic member 1 is connected between the slider and the slide groove, the suction cup is elastically connected to the slider through the elastic member 2, and when the suction cup rotates downward following the conveyor belt, the driving component 2 drives the elastic member 2 to contract, and when the suction cup is aligned with the silicon steel sheet in the storage box, the driving component 2 cancels the restriction on the elastic member 2, and the elastic force of the elastic member 2 drives the suction cup to squeeze and adsorb on the silicon steel sheet.

[0015] Preferably, the driving component 2 includes a stop plate fixedly connected to the elastic member 2 and a stop rail fixedly connected to the machine body. When the suction cup follows the conveyor belt to rotate from top to bottom, the corresponding stop plate abuts against the stop rail and gradually moves toward the direction approaching the conveyor belt under the extrusion of the stop rail. When the stop plate detaches from the stop rail, the elastic force of the elastic member 2 drives the suction cup to be squeezed and adsorbed on the silicon steel sheet.

[0016] The driving of the suction cup is achieved through the cooperation of the mechanical structure of the stop plate and the stop guide rail. Compared with the control by the electric control mechanism, it not only reduces the cost, but also avoids the problem of the electric control circuit being easily entangled during the rotation of the conveyor belt.

[0017] Preferably, guide plates are symmetrically arranged in the guide groove along the front-to-back direction, a space for the second elastic member to move is formed between the two guide plates, and guide slopes are respectively arranged at the left and right ends of the guide plate. When the conveyor belt drives the second elastic member to move toward the guide groove until the stop plate contacts the guide slope, the guide slope squeezes the stop plate to drive the second elastic member to contract, so that the silicon steel sheet adsorbed by the suction cup is tightly attached to the wiping plate.

[0018] The guide slope causes the stopper to move downward, thereby causing the elastic member 2 to contract and store energy. The elastic member 2 makes the silicon steel sheet fit tightly against the wiping plate through the connected suction cup, thereby enhancing the wiping effect of the wiping plate on the silicon steel sheet.

[0019] Preferably, the rising section of the wiping plate is provided with rotating rollers at intervals along the left-right direction.

[0020] Preferably, an auxiliary component is arranged between the storage box and the wiping component, and the auxiliary component includes a driven gear and a conveying roller rotatably connected to the body, a torsion spring is arranged at the rotation connection between the driven gear and the body, the driven gear is connected to the conveying roller through a transmission belt, and racks corresponding to each of the suction cups are arranged at intervals on the conveyor belt, and when the conveyor belt drives the rack to pass through the driven gear, the rack drives the driven gear to rotate, and the torsion spring stores force.

[0022] Preferably, the pushing assembly comprises a pushing plate and an automatic telescopic cylinder, the automatic telescopic cylinder is fixedly connected to the machine body, and the pushing plate is fixedly connected to a driving end of the automatic telescopic cylinder.

[0023] The beneficial effects of the present invention are as follows: the present invention automatically absorbs the silicon steel plate through the suction cup, and in the process of being conveyed by the conveyor belt, wipes the two sides of the silicon steel plate through the wiping component one and the wiping component two, thereby realizing automatic cleaning of the silicon steel plate, improving the cleaning efficiency, reducing manual participation, and reducing the probability of the silicon steel plate causing scratches to the staff; The present invention conveys the silicon steel plate by means of a conveyor belt and a suction cup. When the cleaning is completed and the material is unloaded, the suction cup is controlled to cancel the adsorption of the silicon steel plate, and the silicon steel plate is lifted away or conveyed away by means of a conveyor belt. The silicon steel plate will not be damaged by collision, and the quality of the silicon steel plate is ensured.

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 10 As shown, a transformer core cleaning device of the present invention comprises a body 1 and a transmission assembly arranged on the body 1, wherein the transmission assembly comprises a conveyor belt 2 and a driving assembly 1 for driving the conveyor belt 2 to rotate. The driving assembly 1 comprises a motor 1 (not shown in the figure) and two transmission rollers 1 21, wherein the motor 1 is fixedly mounted on the body 1 by bolts, and the two transmission rollers 1 21 are respectively rotatably connected to the body 1, and one of the transmission rollers 1 21 is fixedly connected to the output end of the motor 1, and the two transmission rollers 1 21 are respectively in contact with the inner side of the conveyor belt 2. The motor 1 drives the transmission roller 1 21 to drive the conveyor belt 2 to rotate, and the conveyor belt 2 is defined to rotate counterclockwise, that is, when the conveyor belt 2 is above the transmission roller 1 21, it is transmitted from right to left, and when it is below the transmission roller 1 21, it is transmitted from left to right.

[0037] The machine body 1 is provided with a storage box 11 below the conveyor belt 2, and the storage box 11 is used to place the silicon steel plates 9 of the transformer core. Suction cups 3 are evenly spaced on the conveyor belt 2, and the suction cups 3 are connected to a driving component 2 that drives them to adsorb the silicon steel plates 9. The bottom of the storage box 11 is provided with a pushing component for pushing the silicon steel plates 9 of the transformer core upward, and the pushing component includes a pushing plate 12 and an automatic telescopic cylinder 13, and the automatic telescopic cylinder 13 is fixedly connected to the machine body 1, and the pushing plate 12 is fixedly connected to the driving end of the automatic telescopic cylinder 13. As an example, the automatic telescopic cylinder 13 is an electric telescopic cylinder. After the stacked silicon steel plates 9 are placed in the storage box 11, the automatic telescopic cylinder 13 drives the pushing plate 12 to push the silicon steel plates 9 upward to ensure that the distance between the silicon steel plates 9 and the suction cups 3 is stable within a certain range, and to ensure that the driving component 2 can drive the suction cups 3 to adsorb onto the silicon steel plates 9.

[0038] A wiping component 1 is provided below the conveyor belt 2, and a wiping component 2 is provided above the conveyor belt 2. The wiping component 1 includes a wiping belt 4 and a driving component 3 for driving the wiping belt 4 to rotate. The wiping belt 4 includes a mounting belt and a sponge fixed to the outside of the mounting belt. The driving component 3 includes a motor 2 (not shown in the figure) and two transmission rollers 2 41. The motor 2 is fixedly installed on the machine body 1 by bolts. The two transmission rollers 2 41 are respectively rotatably connected to the machine body 1, and one of the transmission rollers 2 41 is fixedly connected to the output end of the motor 2. The two transmission rollers 2 41 are respectively in contact with the inner side of the mounting belt. The motor 2 drives the transmission roller 2 41 to drive the wiping belt 4 to rotate. The rotation direction of the wiping belt 4 is the same as that of the conveyor belt 2, that is, the wiping belt 4 also rotates counterclockwise. When the wiping belt 4 is above the transmission roller 2 41, it moves from right to left, and when it is below the transmission roller 2 41, it moves from left to right. The second wiping component comprises a wiping plate 5 fixedly connected to the body 1 , the wiping plate 5 comprises a mounting plate and a sponge fixed to the upper surface of the mounting plate, and a guide groove 51 for the suction cup 3 to pass through is provided on the wiping plate 5 .

[0039] When the suction cup 3 rotates to the bottom of the transmission roller 1 21 following the conveyor belt 2, the driving component 2 drives the suction cup 3 to absorb the silicon steel plate 9 in the storage box 11, and moves from left to right along with the conveyor belt 2. Since the wiping belt 4 moves from right to left when it is above the transmission roller 2 41, when the silicon steel plate 9 passes above the wiping belt 4, the wiping belt 4 wipes the first side of the silicon steel plate 9 in the opposite direction of the movement direction of the wiping belt 4. When the suction cup 3 drives the silicon steel plate 9 to rotate to the top of the transmission roller 1 21, the silicon steel plate 9 moves from right to left following the conveyor belt 2. At this time, the wiping plate 5 is located between the silicon steel plate 9 and the conveyor belt 2, and the wiping plate 5 wipes the second side of the silicon steel plate 9, realizing automatic cleaning of the silicon steel plate 9 and improving the cleaning efficiency.

[0040] Since silicon steel sheets 9 are usually thin, adjacent silicon steel sheets 9 may be adsorbed and bonded together. When the suction cup 3 grabs the top silicon steel sheet 9, two silicon steel sheets 9 that are arranged in a multi-piece arrangement may be taken away. When the suction cup 3 drives the silicon steel sheet 9 to move onto the wiping belt 4, since the movement direction of the wiping belt 4 is opposite to that of the silicon steel sheet 9, other silicon steel sheets 9 adhered to the bottom of the silicon steel sheet 9 will be rubbed, so that the adhered silicon steel sheet 9 is separated from the silicon steel sheet 9 adsorbed by the suction cup 3, and the adhered silicon steel sheet 9 is pushed back to the top of the storage box 11, which solves the problem that the stacked silicon steel sheets are not easy to separate, resulting in the stacked surface being unable to be wiped.

[0041] like Figure 4As shown, the conveyor belt 2 is provided with a slide groove 22 extending in the front-to-back direction, and a slider 23 is slidably connected in the slide groove 22. The slider 23 is elastically connected to the slide groove 22 in the front-to-back direction through an elastic member 1 24. The suction cup 3 is elastically connected to the slider 23 through an elastic member 2 31. As an example, the elastic member 1 24 and the elastic member 2 31 are both elastic telescopic rods. The elastic telescopic rod includes an outer sleeve rod and an inner sleeve rod that are plugged into each other, and a spring is connected between the outer sleeve rod and the inner sleeve rod.

[0042] like Figures 4 to 6 As shown, the suction cup 3 is fixedly connected to the inner sleeve rod of the second elastic member 31, and the outer sleeve rod of the second elastic member 31 is fixedly connected to the slider 23. The second driving assembly includes a stopper 32 fixedly connected to the inner sleeve rod of the second elastic member 31 and two stopper guide rails 6 fixedly connected to the body 1. The two stopper guide rails 6 are arranged side by side in the front-to-back direction, and a space is formed between the two stopper guide rails 6 for the second elastic member 31 to pass through.

[0043] As the suction cup 3 rotates from top to bottom following the conveyor belt 2, the corresponding stop plate 32 will abut against the stop guide rail 6 and gradually move toward the direction close to the conveyor belt 2 under the extrusion of the stop guide rail 6, so that the elastic part 2 31 is compressed to accumulate force. When the stop plate 32 separates from the stop guide rail 6, the elastic force of the elastic part 2 31 drives the suction cup 3 to pop out quickly, so that the suction cup 3 is squeezed and adsorbed on the silicon steel sheet, thereby enabling the suction cup 3 to grasp the silicon steel sheet.

[0044] like Figure 1 , Figure 4 and Figure 7 As shown, an inclined section 52 is provided in the middle of the guide groove 51, and the guide groove 51 of the inclined section 52 is inclined backward from right to left. A push block 14 corresponding to the inclined section 52 is fixedly connected to the rear side of the machine body 1. After the suction cup 3 drives the silicon steel plate 9 to move above the transmission roller 1 21, the elastic member 2 31 corresponding to the suction cup 3 will enter the guide groove 51. As the conveyor belt 2 continues to move, the elastic member 2 31 will come to the inclined section 52 of the guide groove 51 and move backward under the guidance of the inclined section 52. When the elastic member 2 31 moves backward, it will simultaneously drive the suction cup 3 and the slider 23 to move backward. The slider 23 squeezes the elastic member 1 24 backward, causing the elastic member 1 24 to contract and accumulate force. The push block 14 stops the silicon steel plate 9 adsorbed by the suction cup 3, preventing the silicon steel plate 9 from moving backward with the suction cup 3. Therefore, the suction cup 3 will move relative to the silicon steel plate 9, exposing the position on the silicon steel plate 9 where the suction cup 3 was originally adsorbed, so that the wiping plate 5 can wipe the part originally covered by the suction cup 3, thereby achieving the effect of fully cleaning the two sides of the silicon steel plate 9. After the elastic member 2 31 corresponding to the suction cup 3 is separated from the guide groove 51 , the slider 23 will be reset under the elastic force of the elastic member 1 24 , and the slider 23 will drive the elastic member 2 31 and the suction cup 3 to reset.

[0045] like Figure 2 , Figure 5 and Figure 7 As shown, the wiping plate 5 is provided with a rising section 53 near the left end, and the guide groove 51 is provided with a contraction section 54 corresponding to the position of the rising section 53. When the conveyor belt 2 drives the suction cup 3 and the elastic member 2 31 to move along the guide groove 51 to the rising section 53, the rising section 53 of the wiping plate 5 will lift the silicon steel plate 9 upward, and the contraction section 54 of the guide groove 51 will squeeze the front and rear sides of the suction cup 3, so that air enters between the suction cup 3 and the silicon steel plate 9, thereby achieving the effect of rapid separation of the suction cup 3 and the silicon steel plate 9. The rising section 53 of the wiping plate 5 is provided with a plurality of rotating rollers 55 at intervals along the left and right directions, so as to facilitate the unloading of the silicon steel plate 9 that has been cleaned.

[0046] like Figure 2 , Figures 7 to 9 As shown, guide plates 56 are symmetrically arranged in the guide groove 51 along the front-to-back direction. The guide plates 56 extend from right to left to the starting position of the contraction section 54 of the guide groove 51. A space for the elastic member 2 31 to move is formed between the two guide plates 56. The left and right ends of the guide plate 56 are respectively provided with guide slopes 57. When the conveyor belt 2 drives the elastic member 2 31 to move leftward until the stopper 32 contacts the guide slope 57 of the guide plate 56, the guide slope 57 squeezes the stopper 32 to move downward, and the stopper 32 drives the elastic member 2 31 to contract and store force. The elastic member 2 31 drives the silicon steel sheet adsorbed by the suction cup 3 to be closely attached to the wiping plate 5 through the suction cup 3, thereby improving the wiping effect of the wiping plate 5 on the silicon steel sheet 9.

[0047] like Figure 2 and Figure 3 As shown, an auxiliary component is arranged between the storage box 11 and the wiping component 1, and the auxiliary component includes a driven gear 7 and a conveying roller 71 which are rotatably connected to the body 1. A torsion spring is arranged at the rotating connection between the driven gear 7 and the body 1. The driven gear 7 is located above the conveying roller 71 and is connected to the conveying roller 71 through a transmission belt 72. Racks 25 corresponding to each suction cup 3 are arranged at intervals on the conveyor belt 2. When the conveyor belt 2 drives the rack 25 to pass through the driven gear 7, the rack 25 drives the driven gear 7 to rotate clockwise, the torsion spring accumulates force, and the driven gear 7 drives the conveying roller 71 to rotate clockwise through the transmission belt 72. The conveying roller 71 assists in conveying the silicon steel plate 9 adsorbed by the suction cup 3 to the right. When other silicon steel plates 9 are adhered to the bottom of the silicon steel plate 9, the wiping belt 4 will rub the other silicon steel plates 9 to the left. At the same time, after the rack 25 is disengaged from the driven gear 7, the torsion spring will drive the driven gear 7 to rotate counterclockwise, and the driven gear 7 drives the conveying roller 71 to rotate counterclockwise through the transmission belt 72. The conveying roller 71 assists in conveying the other silicon steel plates 9 rubbed by the wiping belt 4 to the left, which is beneficial for the other adhered silicon steel plates 9 to return to their original positions and is beneficial for the subsequent suction cups 3 to smoothly adsorb the silicon steel plates 9.

[0048] The bottom of the machine body 1 is provided with a collecting tank 15 and a cleaning tank 16 located below the wiping belt 4. The collecting tank 15 is provided with a squeezing assembly for squeezing the sponge, and the squeezing assembly includes a clamping roller 8 and a partition plate 81. The partition plate 81 is located between the cleaning tank 16 and the collecting tank 15, and separates the cleaning tank 16 from the collecting tank 15. The clamping roller 8 is fixedly connected to the partition plate 81 through a connecting rod. The wiping belt 4 is passed between the clamping roller 8 and the partition plate 81. During the rotation of the wiping belt 4, the clamping roller 8 and the partition plate 81 squeeze the wiping belt 4, and squeeze the impurities adsorbed by the sponge of the wiping belt 4 into the collecting tank 15.

[0049] The cleaning tank 16 is filled with cleaning agent, and the wiping belt 4 squeezed by the squeezing assembly enters the cleaning tank 16. The sponge of the wiping belt 4 absorbs the cleaning agent in the cleaning tank 16 and waits to rotate above the second driving roller 41 to wipe the silicon steel plate 9.

[0050] The specific working process of a cleaning device for a transformer core of the present invention is as follows: the automatic telescopic cylinder 13 drives the push plate 12 to push the silicon steel plate 9 upward to a preset position; during the process of the suction cup 3 following the conveyor belt 2 rotating from top to bottom, the corresponding stop plate 32 abuts against the stop guide rail 6, and gradually moves in the direction close to the conveyor belt 2 under the extrusion of the stop guide rail 6, so that the elastic member 2 31 is compressed to store force, and when the stop plate 32 is separated from the stop guide rail 6, the elastic force of the elastic member 2 31 drives the suction cup 3 to pop out quickly, and the suction cup 3 adsorbs the silicon steel sheet; as the conveyor belt 2 continues to rotate, the suction cup 3 drives the silicon steel sheet 9 to move from left to right, and the silicon steel sheet 9 passes over the wiping belt 4, and the wiping belt 4 It moves from right to left to wipe the first side of the silicon steel plate 9. When other silicon steel plates 9 are adsorbed and bonded to the bottom of the silicon steel plate 9, the wiping belt 4 pushes the silicon steel plate 9 bonded to the bottom to the left, so that the adhered silicon steel plate 9 moves to the left and breaks contact with the silicon steel plate 9 adsorbed by the suction cup 3, ensuring that the silicon steel plate 9 adsorbed by the suction cup 3 is cleaned; as the conveyor belt 2 continues to rotate, the suction cup 3 drives the silicon steel plate 9 to move above the transmission roller 1 21, and the stopper 32 on the elastic member 2 31 enters under the guide plate 56 under the extrusion of the guide slope 57. The elastic member 2 31 drives the silicon steel sheet adsorbed by the suction cup 3 to be close to the wiping plate 5 through the suction cup 3, and the wiping plate 5 wipes the second side of the silicon steel plate 9.

[0051] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.

When the guide groove guides the suction cup to move along the inclined section, the elastic member is subjected to force, and the push block blocks the silicon steel plate adsorbed by the suction cup from following the movement of the suction cup, and the suction cup moves relative to the corresponding silicon steel plate, so that the wiping plate wipes the position on the silicon steel plate originally covered by the suction cup.

3. The transformer core cleaning device according to claim 2, characterized in that: The wiping plate is provided with an ascending section, and the guide groove is provided with a contraction section corresponding to the position of the ascending section. The contraction section squeezes the suction cup to cancel the adsorption of the silicon steel plate, and the ascending section guides the silicon steel plate to move away from the suction cup so that the suction cup and the silicon steel plate are out of contact.

4. The transformer core cleaning device according to claim 3, characterized in that: The conveyor belt is provided with a slide groove extending in the front-to-back direction, a slider is slidably connected in the slide groove, the elastic member 1 is connected between the slider and the slide groove, the suction cup is elastically connected to the slider through the elastic member 2, and when the suction cup rotates downward following the conveyor belt, the driving component 2 drives the elastic member 2 to contract, and when the suction cup is aligned with the silicon steel sheet in the storage box, the driving component 2 cancels the restriction on the elastic member 2, and the elastic force of the elastic member 2 drives the suction cup to squeeze and adsorb on the silicon steel sheet.

5. The transformer core cleaning device according to claim 4, characterized in that: The second driving component includes a stop plate fixedly connected to the second elastic member and a stop rail fixedly connected to the machine body. When the suction cup rotates from top to bottom following the conveyor belt, the corresponding stop plate abuts against the stop rail and gradually moves toward the direction approaching the conveyor belt under the pressure of the stop rail. When the stop plate is separated from the stop rail, the elastic force of the second elastic member drives the suction cup to be squeezed and adsorbed on the silicon steel sheet.

6. The transformer core cleaning device according to claim 5, characterized in that: Guide plates are symmetrically arranged in the guide groove along the front-to-back direction, and a space for the second elastic member to move is formed between the two guide plates. Guide slopes are respectively arranged at the left and right ends of the guide plates. When the conveyor belt drives the second elastic member to move toward the guide groove until the stop plate contacts the guide slope, the guide slope squeezes the stop plate to drive the second elastic member to contract, so that the silicon steel sheet adsorbed by the suction cup is tightly attached to the wiping plate.

7. The transformer core cleaning device according to claim 3, characterized in that: The rising section of the wiping plate is provided with rotating rollers at intervals along the left and right directions.

8.
