Description

Technical Field

[0001] This invention belongs to the field of transformer core stacking technology, specifically relating to an intelligent stacking device for transformer cores. Background Technology

[0002] The transformer core is the core component of a transformer, and it is made of silicon steel sheets (including ferrite sheets, edge sheets and center core sheets) stacked layer by layer.

[0003] Currently, transformer core stacking is mostly done manually or semi-automatically. Existing stacking equipment has the following problems during use: First, the positioning of silicon steel sheets mostly uses internal perforation limiting, which requires pre-machining positioning holes on the silicon steel sheets. This not only increases the processing steps, but the positioning holes also damage the magnetic circuit structure of the silicon steel sheets, affecting the electromagnetic performance of the core. Second, the positioning structure of the material table is fixed and can only accommodate silicon steel sheets of a single specification. When changing the core specification, the positioning components need to be manually adjusted, resulting in low changeover efficiency and inability to meet the production needs of multiple specifications and small batches. Third, the stacking station is usually designed as a single station. After stacking at one station, the machine needs to be stopped to remove the finished core and re-load it, which cannot achieve continuous stacking production and results in low equipment utilization. Fourth, the suction cups of the gripping components at the end of the robotic arm are arranged in a fixed manner and cannot be adaptively adjusted according to the different sizes and quantities of the wafers, edge wafers, and central core wafers, resulting in poor gripping stability. Fifth, the various mechanisms operate independently and lack linkage and collaborative control, resulting in uncoordinated stacking cycles and difficulty in further improving production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent stacking device for transformer cores to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An intelligent stacking device for transformer cores includes a stacking platform. A first robotic arm is provided on one side of the stacking platform, and a pre-loading platform for silicon steel sheets is provided on one side of the first robotic arm. A second robotic arm is provided on the other side of the stacking platform, and a side and center column sheet loading platform is provided on one side of the second robotic arm. Positioning posts are provided on both the pre-loading platform for silicon steel sheets and the side and center column sheet loading platforms. The positioning posts abut against the outer wall of the silicon steel sheets. The ends of the first and second robotic arms are provided with gripping components. The bottom of each gripping component is provided with several vacuum suction cups, and the number of vacuum suction cups at the bottom of each gripping component corresponds to the number of silicon steel sheets gripped.

[0006] In a preferred embodiment, the stacking platform includes a travel guide rail, on which a first station, a second station, and a third station are sequentially arranged. The bottom of the second station is provided with an electric locking pressure plate, and the top of each assembly station is provided with a stacking support assembly.

[0007] In a preferred embodiment, each of the stacked support assemblies includes eight movable guide plates slidably connected to each workstation. Each workstation has two first handwheels with double-threaded screws symmetrically rotatably connected. Every four movable guide plates are threaded to both sides of a double-threaded screw. The workstation is provided with two linear guide rails perpendicular to the eight movable guide plates, and the eight movable guide plates are slidably connected to the two linear guide rails.

[0008] In a preferred embodiment, each of the movable plates at both ends of the double-threaded screw is slidably connected to a fixed side box. The two movable plates in the middle are slidably connected to a support base. Each support base has a support column on its top. Each fixed side box is threadedly connected to one side of each support base with a locking screw. Each fixed side box is rotatably connected to a second handwheel with a double-threaded screw. The double-threaded screw of each second handwheel is symmetrically threaded to two movable plates slidably connected inside the fixed side box. A support frame for supporting an iron core is sandwiched between the four sets of movable plates located at the four corners.

[0009] In a preferred embodiment, the gripping assembly includes a first connecting seat and a second connecting seat connected to the end effectors of the first robotic arm and the second robotic arm. Each connecting seat has two first adjusting guide rails fixedly connected to its bottom. Sliding seats are slidably connected to both sides of the two first adjusting guide rails. An adjusting frame is slidably connected to the bottom of each sliding seat. Vacuum suction cups are located at the bottom of the adjusting frame. One of the sliding seats has a drive cylinder on one side, and a transmission screw is mounted on the output shaft of the drive cylinder. The other sliding seat is threaded to the outside of the transmission screw. Compared to the gripping assembly at the bottom of the pre-loading platform for the side plates and the central column plate, the gripping assembly located above the side plate and the central column plate has an additional adjusting frame fixedly connected to the middle of the first adjusting guide rail. Furthermore, multiple vacuum suction cups are equidistantly fixedly connected to the bottom of this adjusting frame.

[0010] In a preferred embodiment, the side piece and center column piece material platforms and the pre-loading material platform for the er piece are all provided with support components for supporting the er piece, side piece and center column piece. The support components include two parallel vertical guide rails fixedly connected above the material platform. Multiple moving positioning frames are slidably connected to the outside of the vertical guide rails. The top of each moving positioning frame is bolted to a positioning column. The top of the material platform is fixedly connected to a positioning plate located outside the positioning column. A vertical drive motor is provided at one end of the two vertical guide rails. A linear screw threadedly connected to the multiple moving positioning frames is driven on the output shaft of the vertical drive motor.

[0011] In a preferred embodiment, a transverse drive motor is fixedly connected to one side of the material platform, and a drive gear is fixedly connected to the output shaft of the transverse drive motor. Two transmission screws are rotatably connected to the top of the material platform, and driven gears are fixedly connected to the ends of the two transmission screws. A transmission toothed belt is sleeved on the outside of the two driven gears, and the bottom of the transmission toothed belt abuts against the outside of the drive gear.

[0012] In a preferred embodiment, a side drive motor is fixedly connected to one side of the material platform, and another transmission screw is fixedly connected to the output shaft of the side drive motor. Two side shift supports are symmetrically threaded to the external sides of the transmission screws, and two center abutment plates are symmetrically threaded to the external sides of the transmission screw in the middle.

[0013] In a preferred embodiment, a controller is also included. The controller is electrically connected to the vertical drive motor, the horizontal drive motor, and the side drive motor, respectively. The controller controls the vertical drive motor to drive the moving positioning frame to rise and fall along the vertical guide rail according to the specifications of the silicon steel sheets to be stacked. It controls the horizontal drive motor to drive the transmission screw to rotate through the drive gear, the transmission belt, and the driven gear. It controls the side drive motor to drive the side shift support and the center contact plate to move laterally, so that the positioning column, the side shift support, and the center contact plate abut against the outer wall of the silicon steel sheet, thereby realizing the adaptive positioning of silicon steel sheets of different specifications.

[0014] In a preferred embodiment, the controller is also electrically connected to the first robotic arm, the second robotic arm, the drive cylinder, and the electric locking plate, respectively. The controller controls the first robotic arm to pick up silicon steel sheets from the pre-loading platform and the second robotic arm to pick up side and central column sheets from the side and central column sheet loading platform. The sheets are alternately stacked on the stacking platform in the order of two silicon steel sheets, two side sheets, and one central column sheet per layer. The controller matches the number of vacuum suction cups of the gripping components to the number of silicon steel sheets to be picked up. When the stacking of a station is completed, the controller controls the electric locking plate to release and controls the stacking platform to move along the travel guide rail to switch to the next station, realizing continuous intelligent stacking of multiple stations.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This intelligent stacking equipment for transformer cores replaces the traditional internal perforation limiting method with an external wall contact positioning structure consisting of positioning columns, lateral support seats, and a central contact plate. This eliminates the need to machine positioning holes on the silicon steel sheets, ensuring the integrity of the magnetic circuit of the silicon steel sheets and improving the electromagnetic performance of the core. At the same time, the external wall contact positioning fully exposes the upper surface of the silicon steel sheets, facilitating stable gripping by the vacuum chuck and improving stacking efficiency and accuracy.

[0016] This intelligent stacking equipment for transformer cores utilizes a multi-degree-of-freedom adaptive adjustment mechanism composed of vertical, horizontal, and side drive motors. The controller automatically adjusts the positions of the positioning columns, side-shifting supports, and central contact plates according to the specifications of the silicon steel sheets to be stacked, enabling rapid changeover and precise positioning of silicon steel sheets of different specifications. Simultaneously, in conjunction with the differentiated vacuum suction cup gripping components at the ends of the dual robotic arms, the sheets, edge sheets, and central column sheets can be stably gripped, improving the equipment's versatility and gripping reliability.

[0017] This intelligent stacking equipment for transformer cores uses a controller to link and control the first robotic arm, the second robotic arm, and the stacking carriage. The equipment alternately grabs and stacks two laminations, two side laminations, and one central column lamination per layer, ensuring a coordinated and orderly stacking rhythm. Once the stacking at one station is completed, the controller automatically releases the electric locking plate and drives the stacking carriage to move along the guide rail to the next station. This achieves continuous intelligent stacking at multiple stations, significantly improving the automation level and production efficiency of the equipment. Attached Figure Description

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figure 1-7This invention provides an intelligent stacking device for transformer cores, comprising a stacking platform 1, a first robotic arm 2 on one side of the stacking platform 1, a pre-loading platform 3 for sheet metal on one side of the first robotic arm 2, a second robotic arm 4 on the other side of the stacking platform 1, and a side sheet and center sheet loading platform 5 on one side of the second robotic arm 4. The stacking platform 1 includes a traveling guide rail 101, on which a first station 1a, a second station 1b, and a third station 1c are sequentially arranged. An electric locking pressure plate 102 is provided at the bottom of the second station 1b, and a stacking support assembly is provided at the top of each station. Each stacking support assembly includes eight movable guide plates 104 slidably connected to each station. Two first handwheels 103 with double-threaded screws are symmetrically rotatably connected to each station. Every four movable guide plates 104 are threadedly connected to both sides of a double-threaded screw. Two linear guide rails perpendicular to the eight movable guide plates 104 are provided at each station, and all eight movable guide plates 104 are slidably connected to the two linear guide rails. Each of the two movable plates 104 at both ends of the double-threaded screw is slidably connected to a fixed side box 108. The two movable plates 104 in the middle are slidably connected to a support seat 105. Each support seat 105 is provided with a support column 106 on its top. Each fixed side box 108 and one side of each support seat 105 are threadedly connected to a locking screw 107. Each fixed side box 108 is rotatably connected to a second handwheel 109 with a double-threaded screw. The double-threaded screw of each second handwheel 109 is symmetrically threaded to two movable plates 1010 that are slidably connected inside the fixed side box 108. A support frame 1012 for supporting iron core is sandwiched between the four sets of movable plates 1010 located at the four corners.

[0022] During operation, rotating the first handwheel 103 drives eight movable guide plates 104 to move in opposite directions or in opposite directions along the linear guide rail via the double-threaded screw. Adjusting the distance between the support base 105 and the fixed side box 108 adapts to iron cores of different sizes. Rotating the second handwheel 109 drives the movable plate 1010 to move via the double-threaded screw, so that the support frame 1012 is clamped and fixed between the four corner movable plates 1010. Tightening the locking screw 107 fixes the position. After the iron core is stacked on the support frame 1012, it is supported by the support column 106. The electric locking pressure plate 102 locks the second station 1b in the stacking position.

[0023] With the above structure, the stacking platform 1 can be manually adjusted to accommodate iron cores of different specifications. The support column 106 and the support frame 1012 work together to ensure the flatness and stability of the stacked iron cores. The three-station design realizes the continuous flow of waiting for materials, stacking, and discharging, which improves production efficiency.

[0024] Please see Figure 1-7Both the first robotic arm 2 and the second robotic arm 4 are equipped with gripping components at their ends. Each gripping component has several vacuum suction cups 205 at its bottom. The number of vacuum suction cups 205 at the bottom of each gripping component corresponds to the number of silicon steel sheets it grips. Each gripping component includes a first connecting seat 201 and a second connecting seat 401 connected to the end effector of the first robotic arm 2 and the second robotic arm 4. Two first adjusting guide rails 202 are fixedly connected to the bottom of each connecting seat. Sliding seats 203 are slidably connected to both sides of the two first adjusting guide rails 202. Each sliding seat 203 has a... The sliding connection includes an adjustment frame 204, and a vacuum suction cup 205 is located at the bottom of the adjustment frame 204. One of the sliding seats 203 has a drive cylinder 206 on one side, and a transmission screw 207 is provided on the output shaft of the drive cylinder 206. The other sliding seat 203 is threaded to the outside of the transmission screw 207. The gripping assembly located above the side plate and the central column plate material platform 5 has one more adjustment frame 204 fixedly connected to the middle of the first adjustment guide rail 202 than the gripping assembly at the bottom of the pre-loading material platform 3. The bottom of the adjustment frame 204 is also fixedly connected with multiple vacuum suction cups 205 at equal intervals. Above the edge piece and center column piece material platform 5 and the er piece pre-loading material platform 3, there are support components for supporting the er pieces, edge pieces and center column pieces. The support components include two parallel vertical guide rails 504 fixedly connected above the material platform. Multiple moving positioning frames 503 are slidably connected to the outside of the vertical guide rails 504. The top of each moving positioning frame 503 is bolted to the positioning column 502. The top of the material platform is fixedly connected to a positioning plate 501 located outside the positioning column 502. One end of the two vertical guide rails 504 is provided with a vertical drive motor 5010. The output shaft of the vertical drive motor 5010 is driven by a linear screw threadedly connected to the multiple moving positioning frames 503. A transverse drive motor 505 is fixedly connected to one side of the material platform. A drive gear 506 is fixedly connected to the output shaft of the transverse drive motor 505. Two transmission screws 508 are rotatably connected to the top of the material platform. A driven gear 509 is fixedly connected to the end of each of the two transmission screws 508. A transmission toothed belt 507 is sleeved on the outside of the two driven gears 509. The bottom of the transmission toothed belt 507 abuts against the outside of the drive gear 506. A side drive motor 5012 is fixedly connected to one side of the material platform. Another transmission screw 508 is fixedly connected to the output shaft of the side drive motor 5012. Two side shifting supports 5013 are symmetrically threaded to the outside of the two transmission screws 508. Two center contact plates 5011 are symmetrically threaded to the outside of the middle transmission screw 508.

[0025] During operation, the drive cylinder 206 drives the sliding seat 203 to move along the first adjusting guide rail 202 through the transmission screw 207, adjusting the distance between the two side adjusting frames 204 so that the vacuum suction cup 205 matches the size of the silicon steel sheet. The gripping component of the second robotic arm 4 can grip the side piece and the central column piece at the same time because there is an additional set of adjusting frames 204 in the middle. After the silicon steel sheet is placed on the positioning plate 501, the vertical drive motor 5010 drives the moving positioning frame 503 to rise and fall along the vertical guide rail 504 through the linear screw, which in turn drives the positioning column 502 to rise and fall. The horizontal drive motor 505 drives the transmission screw 508 to rotate through the drive gear 506, the transmission belt 507 and the driven gear 509, which causes the positioning plate 501 to move laterally. The side drive motor 5012 drives the side shift support 5013 and the center contact plate 5011 to move laterally through the transmission screw 508, which then contact and limit the silicon steel sheet from the outer wall.

[0026] Through the above structure, the positioning column 502, the lateral support 5013 and the central contact plate 5011 contact and limit the silicon steel sheet from the outer wall, replacing the traditional internal perforation method, ensuring the integrity of the magnetic circuit of the silicon steel sheet. The vacuum suction cup 205 is arranged differently to stably grasp different types of silicon steel sheets, and the multi-motor linkage realizes the adaptive positioning of silicon steel sheets of different specifications.

[0027] Please see Figure 1-7 It also includes a controller, which is electrically connected to the vertical drive motor 5010, the horizontal drive motor 505, the side drive motor 5012, the first robotic arm 2, the second robotic arm 4, the drive cylinder 206, and the electric locking plate 102.

[0028] During operation, the controller controls the vertical drive motor 5010, the horizontal drive motor 505 and the side drive motor 5012 to adjust in conjunction according to the specifications of the silicon steel sheets to be stacked, so that the positioning column 502, the side shift support 5013 and the center contact plate 5011 abut against the outer wall of the silicon steel sheet, thereby achieving adaptive positioning. The controller controls the first robotic arm 2 to grab ergonomic sheets from the ergonomic sheet pre-loading platform 3, and the second robotic arm 4 to grab side sheets and central column sheets from the side sheet and central column sheet platform 5. The sheets are alternately stacked on the stacking platform 1 in the order of two ergonomic sheets, two side sheets and one central column sheet per layer. The controller matches the grabbing of the corresponding silicon steel sheets according to the number of vacuum suction cups 205 of the grabbing components. Once stacking is completed at one workstation, the controller releases the electric locking plate 102 and moves the stacking carriage 1 along the guide rail 101 to switch to the next workstation, achieving continuous intelligent stacking across multiple workstations. Through the controller's coordinated control of various actuators, the stacking cycle is coordinated and orderly, avoiding manual intervention and significantly improving the automation level and stacking efficiency of the equipment. Multi-workstation switching enables continuous production and improves equipment utilization.

[0029] The overall workflow of this invention is as follows: The external feeding mechanism stacks the silicon steel sheets on the silicon steel sheet pre-loading platform 3 and stacks the side sheets and central column sheets on the side sheet and central column sheet platform 5. The controller controls the vertical drive motor 5010, the horizontal drive motor 505 and the side drive motor 5012 of the platform to adjust in linkage according to the specifications of the silicon steel sheets, so that the positioning column 502, the side shift support 5013 and the center contact plate 5011 contact the positioning silicon steel sheets from the outer wall. The first robotic arm 2 and the second robotic arm 4 cooperate with the gripping component to grab the silicon steel sheets from the corresponding platforms respectively. They are alternately stacked on the second station 1b of the stacking platform 1 in the order of two silicon steel sheets, two side sheets and one central column sheet per layer. When the stacking at this station is completed, the electric locking plate 102 is released, and the stacking platform 1 moves along the walking guide rail 101 to transfer the finished iron core to the third station 1c. At the same time, the empty first station 1a moves into the second station 1b position to continue stacking. This cycle is repeated to achieve continuous production.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.

The wafers are alternately stacked on the stacking platform (1) in the order of two wafers, two side wafers and one central column wafer per layer. The controller matches the grabbing of the corresponding silicon steel sheets according to the number of vacuum suction cups (205) of the grabbing components. When the stacking of a station is completed, the controller controls the electric locking plate (102) to release and controls the stacking platform (1) to move along the walking guide rail (101) to switch to the next station, so as to realize multi-station continuous intelligent stacking.
