Description

Technical Field

[0001] The present application relates to the technical field of transformer core production equipment, in particular to an integrated shearing and stacking machine for main transformer cores. Background Art

[0002] With the continuous development of social economy and the increasing improvement of science and technology, people's demand for electric power has been increasing. As a key device in power transmission, transformers play an important role. A core is a key component of a transformer that affects the performance of the transformer.

[0003] Most existing transformer cores are formed by stacking a plurality of silicon steel sheets along the thickness direction into a "日"-shaped structure, and the silicon steel sheets are formed by transverse punching of silicon steel coils by special cutting machines. Meanwhile, to meet requirements, the cutting machine usually punches silicon steel coils into several different types, namely yoke sheets, central column sheets and side sheets. Among them, the side sheets form the top side and bottom side of the "日" shape, the yoke sheets form the left side and right side of the "日" shape, and the central column sheets form the middle part of the "日" shape. Meanwhile, the punched silicon steel sheets generally have round holes on their surfaces.

[0004] With respect to the above-mentioned related technologies, due to the various structural styles of iron cores, after cutting the silicon steel coils, multi-directional stacking is required according to the structural styles of the iron cores. Therefore, in the existing production process of silicon steel sheet iron cores, manual stacking or semi-automatic stacking with manual assistance of silicon steel sheets is generally adopted, which greatly reduces the overall production efficiency of silicon steel sheet iron cores. Summary of the Invention

[0005] In order to improve the stacking efficiency of silicon steel sheets, the present application provides an integrated shearing and stacking machine for main transformer cores.

[0006] The integrated shearing and stacking machine for main transformer cores provided by the present application adopts the following technical scheme: An integrated shearing and stacking machine for main transformer cores comprises an unwinding mechanism, a cutting mechanism, a conveying mechanism and a stacking mechanism, wherein the unwinding mechanism is used for placing silicon steel coil materials, the cutting mechanism is located between the unwinding mechanism and the conveying mechanism, and the cutting mechanism is used for shearing the silicon steel coil materials; the conveying mechanism is located between the cutting mechanism and the stacking mechanism, the conveying mechanism comprises a mounting frame and a lower conveyor belt, the lower conveyor belt is mounted on the mounting frame, and the lower conveyor belt is used for conveying the cut silicon steel sheets to the vicinity of the stacking mechanism; the stacking mechanism comprises a stacking table and a plurality of stacking robots, and the stacking robots are used for conveying the silicon steel sheets on the lower conveyor belt onto the stacking table and stacking the silicon steel sheets into a required shape.

[0007] By adopting the above technical solution, compared with the existing technology of stacking silicon steel sheets using manual or semi-automatic methods with manual assistance, this application enables the stacking robot to grasp the silicon steel sheets by setting the stacking mechanism, thereby transporting the grasped silicon steel sheets to the stacking platform and stacking them according to the pre-input instructions, so that the silicon steel sheets are stacked into the desired shape. This replaces the traditional manual stacking and semi-automatic stacking with manual assistance, improves the stacking efficiency, and thus improves the overall production efficiency of silicon steel sheet cores.

[0008] Preferably, a conveying mechanism is also provided between the lower transmission belt and the stacking platform. The conveying mechanism includes a fixed frame, a grouping component and a conveyor belt. The conveyor belt is installed on the fixed frame. The grouping component is used to divide the silicon steel sheets into several groups and convey the grouped silicon steel sheets to the conveyor belt. The width direction of the conveyor belt is the arrangement direction of the silicon steel sheets in each group.

[0009] By adopting the above technical solution and setting the conveying mechanism, the grouping component can group the silicon steel sheets on the lower conveyor belt into groups of yoke sheets, central column sheets, and edge sheets. At the same time, the grouped silicon steel sheets are transported to the conveyor belt, and then the grouped silicon steel sheets are transported to the end of the conveyor belt near the stacking platform, which facilitates the stacking robot to pick them up and improves the conveying efficiency of silicon steel sheets.

[0010] Preferably, the grouping assembly includes a grouping frame, the conveying mechanism further includes a drive assembly, the fixed frame is also provided with a conveying frame, the conveying frame is provided with a conveying groove, the conveying groove is opened along the conveying direction of the lower conveyor belt, and the end of the conveying groove away from the lower conveyor belt is bent in the width direction of the lower conveyor belt. One end of the grouping frame extends into the conveying groove and contacts the inner sidewall of the conveying groove. The drive assembly is used to drive the grouping frame to slide along the conveying groove, and to arrange the silicon steel sheets on the grouping frame along the width direction of the conveyor belt.

[0011] By adopting the above technical solution and specifically configuring the grouping component and drive component, the grouping frame can be moved along the starting trajectory of the conveyor trough, thereby approaching the position of the conveyor belt. During the displacement of the grouping frame, the silicon steel sheets on the grouping frame are arranged along the width direction of the conveyor belt, so that several groups of silicon steel sheets on the conveyor belt can be arranged in parallel, which effectively facilitates the stacking robot to pick up the silicon steel sheets, thereby facilitating the stacking of silicon steel sheets.

[0012] Preferably, the drive assembly includes a drive component, an adjusting frame, and a sliding frame. The adjusting frame and the sliding frame are slidably connected, and the sliding direction of the adjusting frame is the direction of the bending of the conveyor trough. The sliding frame is slidably connected to a fixed frame, and the sliding direction of the sliding frame is the conveying direction of the lower conveyor belt. The grouping frame is rotatably connected to the adjusting frame. A steering frame extends downward from the rotatable connection of the grouping frame. The steering frame extends into the conveyor trough and contacts the inner sidewall of the conveyor trough. The drive component is used to drive the adjusting frame to move.

[0013] By adopting the above technical solution and specifically configuring the drive components, when the rotating frame is located in a section of the conveyor trough parallel to the conveying direction of the lower conveyor belt, the drive unit drives the adjusting frame to move away from the lower conveyor belt along the trajectory of the conveyor trough. When the bogie is located at the bend of the conveyor trough, the bogie rotates and drives the grouping frame to rotate together, so that the arrangement direction of the silicon steel sheets on the grouping frame is consistent with the width direction of the conveyor belt. At this time, the adjusting frame slides relative to the sliding frame. After that, the drive unit continues to drive the adjusting frame to slide. At this time, the sliding frame stops sliding, and the adjusting frame slides relative to the sliding frame.

[0014] Preferably, the grouping assembly further includes a pusher frame and a switch frame, which are located on both sides of the grouping frame along the width direction of the lower conveyor belt. The bottom end of the switch frame is rotatably connected to the grouping frame. The grouping frame is also provided with a feeding mechanism, which includes a pusher and a linkage component. The pusher is used to drive the pusher frame to approach the switch frame, and the pusher drives the switch frame to rotate downward through the linkage component.

[0015] By adopting the above technical solution and setting the feeding mechanism, the pushing frame can push the silicon steel sheet to slide out of the grouping frame under the drive of the pushing component. At the same time, under the drive of the linkage component, the rotating frame opens, so that the silicon steel sheet can slide along the surface of the rotating frame and fall onto the conveyor belt to complete the conveying of the silicon steel sheet. At the same time, it also reduces the probability of the silicon steel sheet sliding out and falling during the rotation of the adjusting frame.

[0016] Preferably, the mounting frame is also provided with a positioning mechanism at one end near the stacking platform or on the stacking robot. The positioning mechanism includes a positioning column and a lifting assembly. The lifting assembly is used to drive the positioning column to move in the vertical direction and insert it into the circular hole of the silicon steel sheet.

[0017] By adopting the above technical solution, the positioning mechanism is configured such that when the positioning mechanism is set on the mounting frame, and when the silicon steel sheet is transported by the conveyor belt to the end of the lower conveyor belt near the stacking platform, the lifting component can drive the positioning column to rise, thereby inserting it into the round hole on the silicon steel sheet to position the silicon steel sheet. At this time, the lower conveyor belt stops transporting to ensure the accurate position of the silicon steel sheet. When the positioning mechanism is set on the stacking robot, and the stacking robot moves to the end of the lower conveyor belt near the stacking platform, the stacking robot approaches the silicon steel sheet, and at the same time, the lifting component on the stacking robot drives the positioning column to move down and insert it into the silicon steel sheet for positioning.

[0018] Preferably, the number of positioning columns and lifting components is set to two, and they correspond one to one. Each lifting component includes a lifting element and a sliding element. The lifting element is used to drive the positioning column to move vertically, and the sliding element is used to drive the corresponding lifting element to slide along the length direction of the silicon steel sheet.

[0019] By adopting the above technical solution and setting the sliding component, relevant personnel can drive the lifting component to slide by sliding the sliding component, thereby enabling the lifting component to adjust its own position to adapt to silicon steel sheets of different sizes. This ensures that the positioning column can always be inserted into the round hole on the silicon steel sheet, thereby positioning the silicon steel sheet. This increases the applicability of the positioning mechanism and improves the practicality of this application.

[0020] Preferably, the positioning mechanism further includes a drive rack, the sliding component includes a sliding frame, a drive gear and a drive motor, the lifting component is mounted on the sliding frame, the drive gear is rotatably connected to the sliding frame, the drive rack is mounted on the mounting frame, the length direction of the drive rack is the length direction of the silicon steel sheet, the drive rack meshes with the drive gear, and the drive motor is used to drive the drive gear to rotate.

[0021] By adopting the above technical solution and specifically setting the sliding component, relevant personnel can adjust the position of the sliding frame by controlling the rotation direction and number of rotations of the drive motor, so that the position of the sliding frame corresponds to the round hole on the silicon steel sheet, thereby ensuring that the positioning column can always be inserted into the round hole on the silicon steel sheet, and positioning silicon steel sheets of different sizes.

[0022] Preferably, the number of positioning columns and lifting components is set to multiple, and they are set in a one-to-one correspondence.

[0023] By adopting the above technical solution, multiple positioning columns and lifting components are configured, enabling relevant personnel to select the lifting component corresponding to the position of the circular hole on the silicon steel sheet according to the position of the circular hole on the silicon steel sheet, and insert it into the corresponding circular hole, thereby realizing the positioning of silicon steel sheets of different models, thus increasing the scope of application of this application.

[0024] Preferably, the conveying mechanism further includes a magnetic feeding assembly and a testing platform. The magnetic feeding assembly includes an upper conveyor belt and a magnetic suction element. The upper conveyor belt is mounted on a mounting frame and located above the lower conveyor belt. The testing platform is located directly below the upper conveyor belt. The magnetic suction element is installed inside the upper conveyor belt and is used to attract the sheared silicon steel sheets to the lower surface of the upper conveyor belt.

[0025] By adopting the above technical solution and setting up the magnetic suction feeding component and the inspection table, when the silicon steel sheet after the first shearing is conveyed to the upper conveyor belt, the relevant personnel can control the magnetism of the magnetic suction component to make the silicon steel sheet fall onto the inspection table. At this time, the relevant personnel can inspect the silicon steel sheet after the first shearing, thereby ensuring the shearing quality of the silicon steel sheet. When the silicon steel sheet shearing quality is qualified, the relevant personnel control the magnetic suction component to work, thereby conveying the silicon steel sheet to the lower conveyor belt.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The stacking mechanism enables the stacking robot to grab silicon steel sheets, transport them to the stacking platform, and stack them according to pre-input instructions to form the desired shape. This replaces traditional manual stacking and semi-automatic stacking with manual assistance, improving stacking efficiency and thus improving the overall production efficiency of silicon steel cores. 2. The conveying mechanism is designed so that the grouping component can group the silicon steel sheets on the lower conveyor belt into groups of yoke sheets, central column sheets and side sheets. The grouped silicon steel sheets are then transported to the conveyor belt and then transported to the end of the conveyor belt near the stacking platform. This makes it easier for the stacking robot to pick them up and improves the conveying efficiency of the silicon steel sheets. 3. Regarding the positioning mechanism, when the positioning mechanism is installed on the mounting frame, and when the silicon steel sheet is transported by the conveyor belt to the end of the lower conveyor belt near the stacking platform, the lifting component can drive the positioning column to rise, thereby inserting it into the round hole on the silicon steel sheet to position the silicon steel sheet. At this time, the lower conveyor belt stops transporting to ensure the accurate position of the silicon steel sheet. When the positioning mechanism is installed on the stacking robot, and the stacking robot moves to the end of the lower conveyor belt near the stacking platform, the stacking robot approaches the silicon steel sheet, and at the same time, the lifting component on the stacking robot drives the positioning column to move down and insert it into the silicon steel sheet for positioning.

[0038] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0039] Example 1: Embodiment 1 of this application discloses an integrated machine for shearing and stacking the core of a main transformer. (Refer to...) Figure 1 The main transformer core shearing and stacking integrated machine includes an unwinding mechanism 1, a cutting mechanism 2, a conveying mechanism 3, and a stacking mechanism 4. The unwinding mechanism 1 is used to place silicon steel coils. The cutting mechanism 2 is located between the unwinding mechanism 1 and the conveying mechanism 3, and is used to cut the silicon steel coils. The conveying mechanism 3 is located between the cutting mechanism 2 and the stacking mechanism 4. The conveying mechanism 3 includes a mounting frame 31 and a lower conveyor belt 32. The lower conveyor belt 32 is mounted on the mounting frame 31 and is used to transport the cut silicon steel sheets 5 to the vicinity of the stacking mechanism 4. The stacking mechanism 4 includes a stacking platform 41 and several stacking robots 42. The stacking robots 42 are used to transport the silicon steel sheets 5 from the lower conveyor belt 32 to the stacking platform 41 and stack the silicon steel sheets 5 into the required shape.

[0040] Reference Figure 1The unwinding mechanism 1 includes an unwinder 11, which contains an unwinding roller on which the silicon steel coil is wound. The unwinder 11 contains a component that drives the roller to rotate; this component is existing technology and will not be described in detail here. The cutting mechanism 2 is used to cut the silicon steel coil into groups according to different types, namely, yoke sheets, central column sheets, and edge sheets, and cut each group sequentially. Each silicon steel sheet 5 has two round holes after being cut by the cutting mechanism 2.

[0041] Reference Figure 1 and Figure 2 A conveyor belt 33 is also provided between the cutting mechanism 2 and the upper conveyor belt 341. The conveyor belt 33 is mounted on the mounting frame 31, and the end of the conveyor belt 33 near the upper conveyor belt 341 is inclined upward and located below the upper conveyor belt 341. The conveying mechanism 3 also includes a magnetic material feeding assembly 34 and a detection table 35. Optionally, two magnetic material feeding assemblies 34 are provided, and the two magnetic material feeding assemblies 34 are arranged along the conveying direction of the upper conveyor belt 341 and are close to each other.

[0042] Reference Figure 1 and Figure 2 Each magnetic material feeding assembly 34 includes an upper conveyor belt 341, a magnetic suction element 342, a lifting element 343, and a pressing element 344. Optionally, each magnetic material feeding assembly 34 may contain two upper conveyor belts 341 and two lifting elements 343, arranged in a one-to-one correspondence, with the two upper conveyor belts 341 arranged in parallel. Each upper conveyor belt 341 is mounted on the top of the mounting frame 31, and the lifting element 343 is located above the corresponding upper conveyor belt 341.

[0043] Reference Figure 1 and Figure 2 The bottom end of the upper conveyor belt 341 near the upper conveyor belt 33 is close to the top end of the upper conveyor belt 33. The upper conveyor belts 341 in the two magnetic feeding assemblies 34 are close to each other so that the silicon steel sheet 5 can be smoothly transported from the upper conveyor belt 341 near the cutting mechanism 2 to the upper conveyor belt 341 away from the cutting mechanism 2.

[0044] Reference Figure 1 and Figure 2Each lifting component 343 includes a lifting cylinder 3431, a lifting frame 3432, a rotating frame 3433, and a connecting frame 3434. The cylinder body of the lifting cylinder 3431 is rotatably connected to the mounting frame 31 via a pin, and the piston rod of the lifting cylinder 3431 is rotatably connected to one end of the lifting frame 3432 via a pin. Two rotating frames 3433 are provided. Both ends of the lifting frame 3432 are rotatably connected to the top ends of the two rotating frames 3433 via pins. The middle part of each rotating frame 3433 is rotatably connected to the mounting frame 31 via a pin, and the bottom end of each rotating frame 3433 is rotatably connected to the top end of the connecting frame 3434 via a pin. The length direction of the lifting cylinder 3431 is horizontal.

[0045] Reference Figure 1 and Figure 2 The bottom end of the rotating frame 3433 extends to both sides of the upper conveyor belt 341 and extends into the interior space of the upper conveyor belt 341. Optionally, the magnetic attractor 342 is a plurality of electromagnets, and the magnetic attractor 342 is located within the area covered by the belt of the upper conveyor belt 341. Each magnetic attractor 342 is fixedly installed on the bottom wall of the portion of the rotating frame 343 that extends into the interior of the upper conveyor belt 341, and each magnetic attractor 342 is close to the bottom end of the upper conveyor belt 341.

[0046] Reference Figure 1 and Figure 2 The pressing component 344 includes a pressing cylinder 3441 and a pressing frame 3442. The cylinder body of the pressing cylinder 3441 is fixedly mounted to the top of the mounting frame 31 by bolts to the bracket. The pressing cylinder 3441 is located above the upper conveyor belt 341. The piston rod of the pressing cylinder 3441 is vertically downward and extends into the gap between the two corresponding upper conveyor belts 341. The piston rod of the pressing cylinder 3441 is fixedly connected to the top of the pressing frame 3442 by bolts. The width of the pressing cylinder 3441 is smaller than the width of the gap between the two corresponding upper conveyor belts 341.

[0047] Reference Figure 1 and Figure 2 The inspection platform 35 is located directly below the upper conveyor belt 341. Rollers are installed at the bottom of the inspection platform 35 to facilitate its movement. The inspection platform 35 is placed on the ground. After the conveyor belt 33 transports the silicon steel sheet 5, cut by the cutting mechanism 2, to the top of the mounting frame 31, one end of the silicon steel sheet 5 approaches the bottom of the upper conveyor belt 341. At this time, the magnetic suction component 342 attracts the silicon steel sheet 5, causing the top of the silicon steel sheet 5 to be tightly attached to the bottom wall of the upper conveyor belt 341, thereby realizing the transportation of the silicon steel sheet 5.

[0048] Reference Figure 1 and Figure 2Initially, relevant personnel need to inspect the cutting of the silicon steel sheet 5. Therefore, it is necessary to inspect the different types of silicon steel sheets 5 that are cut first. Thus, when the initial yoke sheet, central column sheet, and side sheet are transported via the upper conveyor belt 341, the piston rod of the lifting cylinder 3431 is displaced, which in turn causes the lifting frame 3432 to be displaced. At this time, the corresponding rotating frame 3433 rotates, thereby causing the connecting frame 3434 to move upward, so that the magnetic suction member 342 at the bottom of the connecting frame 3434 moves away from the bottom of the upper conveyor belt 341, thereby reducing the attraction force on the silicon steel sheet 5.

[0049] Reference Figure 1 and Figure 2 When the piston rod of the lifting cylinder 3431 is fully displaced, the piston rod on the pressing cylinder 3441 drives the pressing frame 3442 to move downward, so that the bottom end of the pressing frame 3442 passes through the gap between the two upper conveyor belts 341 and moves to the bottom of the upper conveyor belt 341, thereby pushing the silicon steel sheet 5 adsorbed on the upper conveyor belt 341 to move downward, and then the silicon steel sheet 5 falls onto the inspection table 35. After falling, the relevant personnel inspect the silicon steel sheet 5.

[0050] Reference Figure 1 and Figure 2 After the initial inspection of the silicon steel sheet 5 is completed, the piston rod of the lifting cylinder 3431 moves back, at which point the lifting frame 3432 and the rotating frame 3433 return to their initial positions. During this process, the connecting frame 3434 gradually approaches the bottom wall of the lower conveyor belt 32 and gradually returns to its initial position. Simultaneously, the piston rod of the pressing cylinder 3441 moves upward, causing the pressing frame 3442 to return to the gap.

[0051] Reference Figure 1 and Figure 3 Two lower conveyor belts 32 are configured, arranged in parallel with a gap between them. Each lower conveyor belt 32 is located below the upper conveyor belt 341, with one end of the lower conveyor belt 32 closer to the cutting mechanism 2 and the other end of the upper conveyor belt 341 furthest from the cutting mechanism 2. The top end of the lower conveyor belt 32 is close to the bottom end of the corresponding upper conveyor belt 341. An electromagnetic block for adsorbing the silicon steel sheet 5 is provided in the middle space of each lower conveyor belt 32. Since the electromagnetic block is existing technology, it will not be described in detail here.

[0052] Reference Figure 1 and Figure 3 When the silicon steel sheet 5 is transported via the lower conveyor belt 32, the electromagnetic block in the middle space of the lower conveyor belt 32 attracts the silicon steel sheet 5, so that the silicon steel sheet 5 moves stably together with the lower conveyor belt 32, thereby reducing the probability of relative sliding between the silicon steel sheet 5 and the lower conveyor belt 32 during transport.

[0053] Reference Figure 1 and Figure 3 A positioning mechanism 6 is provided between the gaps of the two lower conveyor belts 32, and the positioning mechanism 6 is located at the end of the lower conveyor belt 32 near the stacking robot 42. The positioning mechanism 6 includes positioning posts 61 and lifting components 62. The number of positioning posts 61 and lifting components 62 is set to multiple, and they are set one-to-one. Optionally, the number of positioning posts 61 and lifting components 62 is set to six, and they are arranged along the conveying direction of the lower conveyor belts 32.

[0054] Reference Figure 1 and Figure 3 Each lifting assembly 62 includes a lifting frame 621 and a lifting cylinder 622. The lifting frame 621 is fixedly mounted on the mounting frame 31 by bolts, and the lifting cylinder 622 is fixedly mounted inside the lifting frame 621, with the piston rod of the lifting cylinder 622 vertically upward. The top end of each lifting cylinder 622 is fixedly connected to the bottom end of the positioning column 61 by bolts, and the top end of each lifting cylinder 622 extends beyond the top end of the lifting frame 621 and is slidably connected to the lifting frame 621. A photoelectric sensor 63 is also provided on the mounting frame 31, which is used to detect the movement position of the silicon steel sheet 5.

[0055] Reference Figure 1 and Figure 3 When the photoelectric sensor 63 detects that the silicon steel sheet 5 has moved to the end of the lower conveyor belt 32 near the detection table 35, and the circular hole on the silicon steel sheet 5 corresponds to the positioning post 61, the lower conveyor belt 32 stops operating. At this time, the electromagnetic block on the lower conveyor belt 32 is de-energized and demagnetized. Then, the two positioning posts 61 that correspond to the two circular holes on the silicon steel sheet 5 move upward under the drive of the corresponding lifting cylinder 622 and are inserted into the corresponding circular holes, thus achieving the positioning of the silicon steel sheet 5.

[0056] Reference Figure 1 and Figure 3 Optionally, the number of stacking robots 42 is set to two, with the two stacking robots 42 located on opposite sides of the lower conveyor belt 32 along its width. Optionally, each stacking robot 42 is displaced relative to the ground via a slide rail. Each stacking robot 42 is equipped with a suction cup 421 for adsorbing the silicon steel sheet 5, and the bottom wall of the suction cup 421 is also provided with several holes for the insertion of positioning posts 61.

[0057] Reference Figure 1 and Figure 3After the positioning column 61 positions the silicon steel sheet 5, the stacking robot 42 moves to a position close to the silicon steel sheet 5 and uses the suction cup 421 to adsorb the silicon steel sheet 5. After adsorption, the stacking robot 42 moves to a position close to the stacking platform 41. At this time, the stacking robot 42 stacks the silicon steel sheet 5 according to the internal input instructions, thereby gradually stacking it into the general shape of the transformer core.

[0058] Optionally, in other embodiments, the positioning mechanism 6 in this embodiment 1 can also be set on the suction cup 421 of the stacking robot 42. The stacking robot 42 intelligently identifies the position of the circular hole on the silicon steel sheet 5 and selects a suitable positioning post 61 to be inserted into the circular hole, thereby realizing the positioning of the silicon steel sheet 5.

[0059] The implementation principle of the integrated shearing and stacking machine for main transformer cores in Embodiment 1 of this application is as follows: During use, the unwinding machine 11 unwinds the silicon steel coil, while the cutting mechanism 2 cuts the silicon steel coil into silicon steel sheets 5. At this time, the conveyor belt 74 transports the cut silicon steel sheets 5 onto the upper conveyor belt 341. When relevant personnel need to inspect the silicon steel sheets 5, the magnetic suction component 342 is lifted by the lifting component 343, and at the same time, the pressing component presses down the silicon steel sheets 5 on the upper conveyor belt 341, causing the silicon steel sheets 5 to fall onto the lower conveyor belt 32 under their own gravity. At this time, relevant personnel can inspect the silicon steel sheets 5.

[0060] When the silicon steel sheet 5 moves to the end of the lower conveyor belt 32 near the inspection table 35, the lower conveyor belt 32 stops. At the same time, the electromagnetic block near the lower conveyor belt 32 is de-energized and demagnetized. At this time, the corresponding positioning post 61, driven by the lifting cylinder 622, is inserted into the round hole on the silicon steel sheet 5 to position the silicon steel sheet 5. Then, the stacking robot 42 moves to a position close to the silicon steel sheet 5 and uses the suction cup 421 to adsorb the silicon steel sheet 5. After adsorption, the stacking robot 42 moves again to a position close to the stacking table 41 to stack the silicon steel sheets 5.

[0061] Example 2: The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 4 The positioning mechanism 6 also includes a drive rack 64, which is located in the gap between the two lower conveyor belts 32 and is fixedly connected to the mounting bracket 31 by bolts. The length direction of the drive rack 64 is the conveying direction of the lower conveyor belts 32. The number of positioning columns 61 and lifting components 62 is set to two, and they are set one-to-one.

[0062] Reference Figure 4Each lifting assembly 62 includes a lifting component 623 and a sliding component 624. Each sliding component 624 includes a sliding frame 6241, a drive gear 6242, and a drive motor 6243. Each sliding frame 6241 is slidably connected to the mounting frame 31 and is sleeved on the drive rack 64. The sliding direction of each sliding frame 6241 is set to the conveying direction of the lower conveyor belt 32.

[0063] Reference Figure 4 The drive motor 6243 is bolted to the side wall of the corresponding sliding frame 6241, and the output shaft of the drive motor 6243 extends into the sliding frame 6241. Optionally, the drive motor 6243 is a stepper motor or a servo motor. The drive motor 6243 is equipped with a brake device, which can lock the output shaft of the drive motor 6243 when the drive motor 6243 stops working. The brake device is existing technology and will not be described in detail here. The drive gear 6242 is fixedly sleeved on the output shaft of the corresponding drive motor 6243 and rotatably connected to the sliding frame 6241. Each drive gear 6242 meshes with the drive rack 64.

[0064] Reference Figure 4 Optionally, the lifting component 623 is a cylinder, and each lifting component 623 is fixedly installed inside the sliding frame 6241. The piston rod of each lifting component 623 extends vertically upward and is fixedly connected to the bottom end of the corresponding positioning post 61. The top end of each positioning post 61 extends out of the sliding frame 6241.

[0065] Reference Figure 4 When the silicon steel sheet 5 needs to be positioned, the output shaft of the drive motor 6243 rotates, causing the drive gear 6242 to rotate. The rotation of the drive gear 6242 drives the sliding frame 6241 to slide as a whole, thereby adjusting the position of the positioning post 61 so that the positioning post 61 fits into the two round holes on the silicon steel sheet 5. After adjustment, the positioning post 61 moves upward under the drive of the corresponding lifting component 623 and is inserted into the corresponding round hole, thus achieving the positioning of the silicon steel sheet 5.

[0066] Optionally, in other embodiments, the positioning mechanism 6 in this embodiment 2 can also be set on the suction cup 421 of the stacking robot 42. The stacking robot 42 intelligently identifies the position of the circular hole on the silicon steel sheet 5 and causes the sliding member 624 to adjust the position of the positioning post 61 so that the positioning post 61 is inserted into the circular hole, thereby realizing the positioning of the silicon steel sheet 5.

[0067] The implementation principle of the integrated shearing and stacking machine for main transformer cores in Embodiment 2 of this application is as follows: When the photoelectric sensor 63 detects that the silicon steel sheet 5 has moved to one end of the lower conveyor belt 32 near the detection table 35, and the circular hole on the silicon steel sheet 5 corresponds to the positioning post 61, the lower conveyor belt 32 stops operating, and the electromagnetic block on the lower conveyor belt 32 is de-energized and demagnetized. At this time, the output shaft of the drive motor 6243 rotates, thereby causing the drive gear 6242 to rotate. The rotation of the drive gear 6242 drives the sliding frame 6241 to slide as a whole, thereby adjusting the position of the positioning post 61 so that the positioning post 61 adapts to the two circular holes on the silicon steel sheet 5. After the adjustment is completed, the positioning post 61 moves upward under the drive of the corresponding drive component 731 and is inserted into the corresponding circular hole, thereby realizing the positioning of the silicon steel sheet 5.

[0068] Example 3: The difference between Embodiment 3 and Embodiment 1 in this application is that: (Refer to...) Figure 5 , Figure 6 and Figure 7 A conveying mechanism 7 is also provided between the lower conveyor belt 32 and the stacking platform 41. The conveying mechanism 7 includes a fixed frame 71, a grouping assembly 72, a drive assembly 73, and a conveyor belt 74. The fixed frame 71 is placed on the ground. A conveyor frame 75 is also provided on the fixed frame 71. A conveyor trough 751 is opened through the top of the conveyor frame 75. The conveyor trough 751 is "L" shaped. The end of the conveyor trough 751 away from the stacking platform 41 is parallel to the conveying direction of the lower conveyor belt 32, and the other end of the conveyor trough 751 is parallel to the width direction of the lower conveyor belt 32.

[0069] Reference Figure 6 and Figure 7 The drive assembly 73 includes a drive component 731, an adjusting frame 732, and a sliding frame 733. The sliding frame 733 is slidably connected to the fixed frame 71 via a slide rail. The sliding direction of the sliding frame 733 is the conveying direction of the lower conveyor belt 32, and the length direction of the sliding frame 733 is the width direction of the lower conveyor belt 32. The adjusting frame 732 is slidably connected to the sliding frame 733, and the sliding direction of the adjusting frame 732 is the length direction of the sliding frame 733.

[0070] Reference Figure 7 and Figure 8 The bottom end of the adjusting frame 732 is also provided with a bogie 734. The top end of the bogie 734 extends upward and passes through the top wall of the adjusting frame 732, and the bogie 734 and the adjusting frame 732 are rotatably connected via bearings. Two steering rollers 7341 are provided on the bottom end of the bogie 734, distributed along the opening direction of the conveying trough 751. Each steering roller 7341 is rotatably connected to the bogie 734 via a pin, and the axis of rotation of the steering roller 7341 is vertical. Each steering roller 7341 is located inside the conveying trough 751 and contacts the inner wall of the conveying trough 751.

[0071] Reference Figure 6 and Figure 7 The grouping assembly 72 includes a grouping frame 721, which is located above the adjusting frame 732. The bottom of one end of the grouping frame 721 is bolted to the top of the bogie 734, which extends out of the adjusting frame 732. The length direction of the grouping frame 721 is the conveying direction of the lower conveyor belt 32. The other end of the grouping frame 721 is close to the end of the lower conveyor belt 32 near the stacking platform 41. Optionally, the drive component 731 is a rotary cylinder. The cylinder body of the drive component 731 is rotatably connected to the fixed frame 71 via a bracket and bearing. The piston rod of the drive component 731 is rotatably connected to the adjusting frame 732 via a pin. The rotatable connection between the drive component 731 and the adjusting frame 732 is located at the end of the adjusting frame 732 near the lower conveyor belt 32.

[0072] Reference Figure 6 , Figure 7 and Figure 8 Initially, the end of the grouping frame 721 furthest from the adjusting frame 732 is close to the lower conveyor belt 32. As the lower conveyor belt 32 transports, it sequentially carries several groups of silicon steel sheets 5. When a silicon steel sheet 5 is transported to the end of the lower conveyor belt 32 near the grouping frame 721, it is gradually pushed into the grouping frame 721 by the lower conveyor belt 32. When the next silicon steel sheet 5 continues to be transported onto the lower conveyor belt 32 and reaches the grouping frame 721, it pushes the previous silicon steel sheet 5 to slide together into the grouping frame 721. When the third silicon steel sheet 5 continues to be transported onto the lower conveyor belt 32 and reaches the grouping frame 721, it pushes the second silicon steel sheet 5 to slide. When the third silicon steel sheet 5 detaches from the lower conveyor belt 32, the first silicon steel sheet 5 abuts against the inner wall of the other end of the grouping frame 721.

[0073] Reference Figure 6 , Figure 7 and Figure 8 At this point, the piston rod of the drive component 731 slides outward, thereby driving the adjusting frame 732 to slide together with the sliding frame 733. When the steering roller 7341 on the bogie 734 slides to the bend on the conveying trough 751, the inner wall of the conveying trough 751 abuts against the steering roller 7341, thereby pushing the bogie 734 to rotate, which in turn causes the grouping frame 721 to rotate 90 degrees. When the steering roller 7341 on the bogie 734 disengages from the bend on the conveying trough 751 and reaches the other end of the conveying trough 751, the sliding frame 733 stops sliding. At this time, the adjusting frame 732 slides relative to the sliding frame 733 and finally reaches the end of the conveying trough 751.

[0074] Reference Figure 6 and Figure 9The conveyor belt 74 is mounted on the fixed frame 71 and located on the side of the conveyor trough 751 away from the lower conveyor belt 32. The conveying direction of the conveyor belt 74 is the same as that of the lower conveyor belt 32, and the width of the conveyor belt 74 is greater than the width of the lower conveyor belt 32. The grouping assembly 72 also includes a pusher frame 722 and a switch frame 723. The pusher frame 722 is located on the side of the grouping frame 721 along its own width direction and near the other end of the conveyor trough 751, and the switch frame 723 is located on the other side of the grouping frame 721 along its own width direction.

[0075] Reference Figure 6 and Figure 9 The pusher frame 722 is embedded in the grouping frame 721 along its length and near the end of the adjusting frame 732, and is slidably connected to the grouping frame 721. The bottom end of the switch frame 723 is rotatably connected to the grouping frame 721 via a pin. The grouping frame 721 is also provided with a feeding mechanism 8, which includes a pusher 81 and a linkage assembly 82. Optionally, the number of pushers 81 is set to several and arranged along the length of the grouping frame 721. The pusher 81 can be a cylinder. The cylinder body of the pusher 81 is fixedly installed on the grouping frame 721 by bolts, and the piston rod of the pusher 81 is fixedly connected to the side wall of the pusher frame 722 away from the switch frame 723 by bolts.

[0076] Reference Figure 6 and Figure 9 The linkage assembly 82 includes a linkage gear 821 and a linkage rack 822. The linkage gear 821 is fixedly connected to one end of the switch frame 723 near the adjusting frame 732, and the linkage gear 821 is coaxially arranged with a rotating pin on the switch frame 723. One end of the linkage rack 822 is fixedly connected to the bottom end of the push frame 722 by welding, and the other end of the linkage rack 822 extends towards the switch frame 723 and meshes with the linkage rack 822. The linkage rack 822 is located above the linkage gear 821.

[0077] Reference Figure 6 , Figure 7 and Figure 9 Initially, the pusher 722 is located at the end of the grouping frame 721 furthest from the switch frame 723, at which point the switch frame 723 is in a closed state. When the grouping frame 721 rotates under the action of the drive member 731 and the conveyor trough 751 and moves to the other end of the conveyor trough 751, the grouping frame 721 approaches the conveyor belt 74, and the length direction of the grouping frame 721 is the width direction of the conveyor belt 74. At this time, the piston rod of the pusher 81 drives the pusher 722 to push the silicon steel sheet 5 on the grouping frame 721 to slide and approach the switch frame 723.

[0078] Reference Figure 6 , Figure 7 and Figure 9During this process, the drive rack 64 drives the drive gear 6242 to rotate, thereby driving the switch frame 723 to rotate downwards. When the silicon steel sheet 5 on the group frame 721 is displaced to one end of the group frame 721 near the switch frame 723, the switch frame 723 rotates at an angle greater than or equal to 90 degrees. At this time, the switch frame 723 is lower than the inner top wall of the group frame 721, allowing the silicon steel sheet 5 to be smoothly pushed out of the group frame 721. Subsequently, the push frame 722 continues to push the silicon steel sheet 5, one end of the switch frame 723 tilts downwards and is positioned directly above the conveyor belt 74, gradually approaching the top of the conveyor belt 74.

[0079] Reference Figure 6 , Figure 7 and Figure 9 During this process, the silicon steel sheet 5 is fully pushed onto the switch frame 723 and slides along the inclined direction of the switch frame 723 onto the conveyor belt 74, thereby transporting the silicon steel sheet 5 onto the conveyor belt 74. After the transport is completed, the piston rod of the pusher 81 returns to its initial position, and drives the pusher frame 722 and the switch frame 723 to return to their initial positions.

[0080] Reference Figure 6 and Figure 10 The conveyor belt 74 has alignment components 9 on both sides along its width, with each alignment component 9 located at the end of the conveyor belt 74 closest to the grouping frame 721. Each alignment component 9 includes an alignment frame 91 and a rotating element 92. Optionally, the rotating element 92 is a stepper motor or a servo motor. A brake device is provided on the rotating element 92; the brake device is existing technology and will not be described in detail here. Each rotating element 92 is fixedly connected to the fixed frame 71 via a bracket and bolts. The output shaft of the rotating element 92 is vertically upward and fixedly connected to the bottom end of the alignment frame 91 via a coupling.

[0081] Reference Figure 6 and Figure 10 The top of each positioning rack 91 is located above the conveyor belt 74. Each positioning rack 91 extends towards the other positioning rack 91 and is close together. The bottom of the end of each positioning rack 91 closest to the other positioning rack 91 is close to the top of the conveyor belt 74. Initially, the sides of the two positioning racks 91 away from the stacking platform 41 are coplanar and perpendicular to the top wall of the conveyor belt 74, and the two positioning racks 91 are close together.

[0082] Reference Figure 6 and Figure 10When the silicon steel sheet 5 slides down from the switch frame 723 onto the conveyor belt 74, the conveyor belt 74 gradually transports each set of silicon steel sheets 5 towards the stacking platform 41. At this time, each silicon steel sheet 5, under the transport of the conveyor belt 74, abuts against the side wall of the alignment frame 91. The tilted silicon steel sheet 5, driven by the conveyor belt 74, continues to abut against the alignment frame 91 and rotates, causing the side wall of the silicon steel sheet 5 to completely abut against the alignment frame 91, thereby straightening the silicon steel sheet 5.

[0083] Reference Figure 6 and Figure 10 After the alignment is complete, the conveyor belt 74 stops transporting. At this time, the rotating component 92 drives the corresponding alignment frame 91 to rotate towards the grouping frame 721. When the rotation angle of the alignment frame 91 is greater than or equal to 90 degrees, the conveyor belt 74 continues to operate, transporting the silicon steel sheet 5 a certain distance. At this time, the rotating component 92 drives the alignment frame 91 to return to its initial position. The conveyor belt 74 continues to transport the silicon steel sheet 5 to one end of itself closest to the stacking platform 41. Then, the stacking robot 42 picks up the silicon steel sheet 5 from the stacking platform 41 and moves it onto the stacking platform 41 for stacking.

[0084] The implementation principle of the integrated shearing and stacking machine for main transformer cores in Embodiment 3 of this application is as follows: When the silicon steel sheet 5 is transported to one end of the lower conveyor belt 32 near the grouping frame 721, the silicon steel sheet 5 is gradually transported into the grouping frame 721 under the push of the lower conveyor belt 32. When all three silicon steel sheets 5 in a group are transported onto the grouping frame 721, the driving component 731 drives the adjusting frame 732 to move, and under the action of the adjusting frame 732 and the bogie 734, the grouping frame 721 rotates, and the adjusting frame 732 finally reaches the end of the conveying trough 751. At this time, the grouping frame 721 is close to the conveyor belt 74.

[0085] Then, the piston rod of the pusher 81 drives the pusher frame 722 to push the silicon steel sheet 5 on the grouping frame 721 to slide. The switch frame 723 rotates and tilts downward under the drive of the linkage assembly 82. When the silicon steel sheet 5 is fully pushed onto the switch frame 723, the silicon steel sheet 5 slides along the tilt direction of the switch frame 723 onto the conveyor belt 74. At this time, the conveyor belt 74 gradually transports each group of silicon steel sheets 5 towards the stacking platform 41, so that the silicon steel sheet 5 abuts against the side wall of the aligning frame 91 under the transport of the conveyor belt 74, until the side wall of the silicon steel sheet 5 completely abuts against the aligning frame 91, thereby aligning the silicon steel sheet 5.

[0086] After the silicon steel sheet 5 has fully returned to its original position, the conveyor belt 74 stops transporting. At this time, the rotating component 92 drives the corresponding positioning frame 91 to rotate. Then, the conveyor belt 74 continues to operate, transporting the silicon steel sheet 5 a certain distance. Next, the rotating component 92 drives the positioning frame 91 back to its initial position. The conveyor belt 74 continues to transport the silicon steel sheet 5 to one end of itself closest to the stacking platform 41. Finally, the stacking robot 42 picks up the silicon steel sheet 5 from the stacking platform 41 and moves it onto the stacking platform 41, thus achieving the stacking of the silicon steel sheet 5.

[0087] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
