[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figures 1-4 This utility model provides a transformer core assembly platform, comprising:

[0038] The workbench 1 has several limiting rods 15 on its top surface. The limiting rods 15 are detachably connected to the workbench 1, and the several limiting rods 15 work together to define the assembly area.

[0039] A pair of limiting plates 3 are arranged opposite each other on the top surface of the workbench 1, and the two ends of the vertical silicon steel sheet abut against the pair of limiting plates 3 respectively. The limiting plates 3 are detachably connected to the workbench 1.

[0040] A pair of lifting plates 4 are arranged opposite each other on both sides of the assembly area. The lifting plates 4 are configured to slide in contact with the side wall of the adjacent outermost vertical silicon steel sheet.

[0041] Several pairs of movable plates 5 are arranged opposite each other and located between two adjacent vertical silicon steel sheets. The worktable 1 is equipped with a drive assembly connected to several pairs of movable plates 5. The movable plates 5 slide in contact with adjacent vertical silicon steel sheets along the length direction of the vertical silicon steel sheets.

[0042] This invention forms an assembly area with a limiting function by fixing a limiting rod 15 on the top surface of the workbench 1, ensuring the stability of the core structure when stacking silicon steel sheets. In addition, a pair of limiting plates 3 are arranged opposite each other along the ends of the vertical silicon steel sheets. The limiting plates 3 abut against the ends of the vertical silicon steel sheets to ensure the position of the vertical silicon steel sheets is aligned. The limiting plates 3 are detachably connected to the workbench 1. After the vertical silicon steel sheets are determined, the limiting plates 3 are removed to make way for the stacking of the horizontal silicon steel sheets. Since the horizontal and vertical silicon steel sheets are inserted, the accurately positioned vertical silicon steel sheets can limit the horizontal silicon steel sheets, thereby improving the stacking effect of the overall core structure.

[0043] Furthermore, the workbench 1 is also equipped with a lifting plate 4 and a moving plate 5. The lifting plate 4 makes sliding contact with the outermost vertical silicon steel sheet to form a leveling effect on the vertical silicon steel sheet. Combined with several pairs of moving plates 5 moving between adjacent vertical silicon steel sheets to level them, the speed of flattening and stacking silicon steel sheets is accelerated, and the assembly efficiency of the transformer core is improved.

[0044] In this technical solution, the limiting rod 15 is fixed between two adjacent vertical silicon steel sheets. Structurally, it does not affect the stacking of horizontal silicon steel sheets. Therefore, the common bolt connection method can be used to fix it, so as to realize the detachable connection between the limiting rod 15 and the worktable 1, and enable the limiting rod 15 to effectively limit and stabilize the vertical silicon steel sheets.

[0045] In this technical solution, the bottom two sides of the limiting plate 3 are integrally formed with inserts, and the top surface of the worktable 1 is provided with slots. The limiting plate 3 and the worktable 1 are detachably connected by inserting the inserts into the slots.

[0046] Furthermore, the driving components include:

[0047] The movable seat 6 is provided in several ways. Several movable seats 6 are arranged in a one-to-one correspondence with several pairs of movable plates 5. A pair of movable plates 5 are slidably connected to each other on both sides of the movable seat 6. The workbench 1 is provided with a first driving member. The driving end of the first driving member is connected to the movable seat 6 so that the movable seat 6 can move along the length of the vertical silicon steel sheet.

[0048] The second driving member is mounted on the movable base 6. The driving end of the second driving member is connected to a pair of movable plates 5 respectively, so that the pair of movable plates 5 move synchronously towards or in opposite directions.

[0049] Several movable seats 6 are used to drive several pairs of movable plates 5 to move. Each movable seat 6 has only one pair of movable plates 5 sliding on the opposite side. The second driving member controls the pair of movable plates 5 to move in opposite directions or towards each other, so that the pair of movable plates 5 contact the side wall of the adjacent vertical silicon steel sheet respectively. Under the premise that the first driving member drives the movable seats 6, they move along the length of the vertical silicon steel sheet to level it.

[0050] Furthermore, the first driving component includes:

[0051] A number of bidirectional lead screws 7 are provided. The top surface of the worktable 1 has grooves between two adjacent vertical silicon steel sheets. The grooves are distributed along the length of the vertical silicon steel sheets. A bidirectional lead screw 7 is connected in any groove. The two ends of the bidirectional lead screw 7 are respectively provided with movable seats 6. The two movable seats 6 move towards each other or in opposite directions.

[0052] The drive motor 8 is fixedly connected inside the worktable 1. The number of drive motors 8 and the number of bidirectional lead screws 7 are the same and correspond one-to-one. The output shaft of the drive motor 8 is coaxially fixedly connected to the adjacent bidirectional lead screw 7.

[0053] The drive motor 8 drives the bidirectional lead screw 7 to rotate, causing the two opposing moving seats 6 to move towards or away from each other. The two pairs of moving plates 5 that are slidably set on the two moving seats 6 are used to level the vertical silicon steel sheets along both ends, thereby improving the leveling stability and enhancing the stacking quality of the vertical silicon steel sheets.

[0054] Specifically, in this technical solution, it is preferred, but not limited to, the use of two bidirectional lead screws 7 to control four moving seats 6 to move four pairs of moving plates 5 synchronously, thereby leveling the three sets of vertical silicon steel sheets.

[0055] Furthermore, it also includes:

[0056] The slider 9 is slidably connected in the groove. The number of sliders 9 and the moving seat 6 are the same and they are fixedly connected in a one-to-one correspondence. The two sliders 9 in the same groove are respectively threaded onto the two ends of the adjacent bidirectional lead screw 7.

[0057] The slider 9 is threadedly connected to the bidirectional lead screw 7, and the slider 9 is slidably connected to the groove, so that the moving seat 6 can slide stably relative to the worktable 1.

[0058] Furthermore, the second drive component includes:

[0059] A servo motor 10 is fixedly connected to the top surface of the movable base 6. The output shaft of the servo motor 10 extends into the movable base 6 and is fixedly connected to a gear 11.

[0060] A pair of toothed plates 12 are slidably connected to each other in the movable seat 6 and respectively mesh with the two sides of the gear 11. The far ends of the pair of toothed plates 12 are respectively connected to a pair of movable plates 5.

[0061] The servo motor 10 rotates the gear 11, which drives a pair of toothed plates 12 to slide synchronously in opposite directions. The toothed plates 12 move the moving plate 5, so that the moving plate 5 slides into contact with the adjacent vertical silicon steel sheet.

[0062] Furthermore, it also includes:

[0063] The connecting block 13 is fixedly connected to one end of the toothed plate 12 that extends out of the movable seat 6. A sliding groove is provided on the side wall of the connecting block 13. The movable plate 5 is slidably connected in the sliding groove. A spring 14 is provided in the sliding groove. The two ends of the spring 14 are fixedly connected to the inner wall of the sliding groove and the movable plate 5, respectively.

[0064] The limiting rod 15 is fixed to the connecting block 13, and the limiting rod 15 is arranged opposite to the adjacent toothed plate 12. The end of the limiting rod 15 away from the connecting block 13 extends into the movable seat 6, and the limiting rod 15 slides with the movable seat 6.

[0065] The connecting block 13 is fixedly connected to the toothed plate 12, and a sliding groove is opened on the side of the connecting block 13 away from the toothed plate 12. The spring 14 provides elastic support for the moving plate 5. At the same time, the limiting rod 15 is fixedly connected to the connecting block 13, and the limiting rod 15 is also slidably connected to the moving seat 6 to maintain the sliding stability of the connecting block 13.

[0066] Furthermore, a slot is provided in the workbench 1, and a servo cylinder 16 is fixedly connected to the bottom of the slot. The piston rod of the servo cylinder 16 extends vertically and is fixedly connected to a support plate 17. A pair of lifting plates 4 are fixedly connected to both sides of the top surface of the support plate 17.

[0067] The servo cylinder 16 drives the support plate 17 to lift the lifting plate 4. During the stacking process, the lifting plate 4 descends into the empty slot to facilitate stacking. As the number of stacking layers increases, the servo cylinder 16 drives the lifting plate 4 to rise. During the rising process, the lifting plate 4 levels the vertical silicon steel sheets it comes into contact with.

[0068] Furthermore, the side of the movable plate 5 facing the adjacent vertical silicon steel sheet has an arc-shaped structure.

[0069] Furthermore, the top of the lifting plate 4 has a rounded corner transitioning towards the side of the adjacent vertical silicon steel sheet.

[0070] Understandably, since the edges formed by the stacking of multiple layers of silicon steel sheets are flat, by setting the contact end between the moving plate 5 and the silicon steel sheet to be arc-shaped, and the contact end between the lifting plate 4 and the silicon steel sheet to be rounded, a smooth transition can be effectively achieved, preventing damage to the silicon steel sheet structure caused by the interlacing shear forces formed on the contact surface.

[0071] The working principle of this utility model of a transformer core assembly platform is as follows:

[0072] Based on the fixed position of the limit rod 15, tie-down straps are laid out at intervals on the workbench 1. Then, three sets of vertical silicon steel sheets are placed on the tie-down straps, with the sides of the vertical silicon steel sheets abutting against the adjacent limit rod 15, and the ends of the vertical silicon steel sheets abutting against the limit plate 3. After removing the limit plate 3, the horizontal and vertical silicon steel sheets are stacked in sequence. The two sets of vertical silicon steel sheets on both sides are used to press and fix the horizontal silicon steel sheets. During the stacking process, the servo cylinder 16 is periodically activated to drive the lifting plate 4 to rise, and at the same time, the servo cylinder 16 is activated to drive the lifting plate 4 to rise. The drive motor 8 and servo motor 10 cause the lifting plate 4 to slide in contact with the side wall of the vertical silicon steel sheet in the vertical direction. The two pairs of moving plates 5 located on both sides of the same bidirectional lead screw 7 move in a direction that approaches each other. During the movement, the moving plates 5 slide in contact with the side wall of the adjacent silicon steel sheet, thereby efficiently leveling the iron core structure until the iron core structure is stacked. Then, the lifting plate 4 is returned to the empty slot, and the limit rod 15 is removed. The binding straps are then tied tightly around the silicon steel sheet in sequence. After the entire iron core is tied, it can be transported.
