Description

Technical Field

[0001] The present invention relates to the technical field of transformer manufacturing, and specifically relates to a transformer core lamination device. Background Art

[0002] The lamination of the transformer core is an important part of the transformer structure. Its main function is to form the magnetic circuit of the transformer and reduce eddy current losses. When laminating the transformer core, it is necessary to use insulating materials to separate adjacent two groups of cores to reduce the short circuit between layers.

[0034] The driving structure includes two rods 14 and two connecting rods 16.

A pushing structure is provided outside the fixing block 24.

[0037] The pushing structure includes a push plate 26 fixedly installed above the fixing block 24. The push plate 26 is inclined. A sliding rod 28 is arranged above the push plate 26. The sliding rod 28 slidably penetrates through the turntable 7. An installation block 27 is arranged above the turntable 7. The lower end of the installation block 27 is inclined. The installation block 27 is in contact and cooperation with the sliding rod 28. The installation block 27 is fixedly connected to the fixing frame 5.

[0038] Specifically, a moving groove 30 is formed on the side of the fixing block 24. A third spring 31 and a positioning block 29 are sequentially movably installed in the moving groove 30 from the inside to the outside. The positioning block 29 slidably penetrates through the mounting frame 23 and extends to the outside of the mounting frame 23. A push block 32 is hinged above the workbench 1. The push block 32 is in contact and cooperation with the positioning block 29.

[0039] Working principle: The insulating material 3 is installed above the supporting plate 2. The hydraulic cylinder 4 can drive the insulating material 3 to move intermittently above the workbench 1 through the supporting plate 2. The iron core is placed on the workbench 1, and the iron core is located below the suction cup 10. Under the action of the support frame 8, the electric push rod 9 is connected to an external power supply, and the electric push rod 9 drives the fixed frame 5 to lift inside the support frame 8. When the fixed frame 5 moves downward, it drives the suction cup 10 to move synchronously. The suction cup 10 contacts the uppermost iron core and adsorbs the iron core.

[0040] Specifically, when the fixed frame 5 moves downward, it can drive the fixed block 24 to move synchronously. When the suction cup 10 stops moving, the fixed block 24 drives the adjusting plate 13 to move downward. Since the shaft member 17 is fixedly connected to the pipeline 11, when the adjusting plate 13 approaches the shaft member 17, the angle between the two connecting rods 16 gradually increases. At this time, the slider 15 slides on the outer surface of the rod member 14, and the first spring 18 deforms under force, thereby driving the piston plate 12 to move inside the pipeline 11 in the direction of the shaft member 17. When the piston plate 12 moves, it can extract the air between the suction cup 10 and the iron core, making the connection between the suction cup 10 and the iron core tighter, which is beneficial to increasing the stability of the suction cup 10 when picking up the iron core.

[0041] When the adjusting plate 13 moves to a certain position, the second spring 21 pushes the limiting block 19 out of the groove 20, enabling the limiting block 19 to penetrate the pipeline 11, thereby facilitating the fixation of the adjusting plate 13 and the pipeline 11 together, so that when the suction cup 10 moves upward, the suction cup 10 will not separate from the iron core.

[0042] Furthermore, when the suction cup 10 moves upward to a certain position, under the action of the fixed frame 5, the motor 6 drives the turntable 7 to rotate, thereby driving the suction cup 10 to rotate around the motor 6. During this process, the slide bar 28 contacts the mounting block 27. Since the lower end surface of the mounting block 27 is inclined, the mounting block 27 can push the slide bar 28 downward. At this time, the slide bar 28 drives the fixed block 24 to rotate 90 degrees around the rotating shaft 25 through the push plate 26. At this time, the suction cup 10 drives the iron core to rotate from a horizontal state to a vertical state.

[0043] Meanwhile, the third spring 31 pushes the positioning block 29 out of the inside of the movable slot 30, enabling the positioning block 29 to penetrate through the mounting bracket 23, so as to keep the iron core in a vertical state. When the iron core moves above the insulating material 3, the fixing bracket 5 drives the iron core to move downward, and the suction cup 10 inserts the iron core between two adjacent groups of insulating materials 3. During this process, the pipeline 11 contacts the adjusting block 22. The adjacent sides of the two adjusting blocks 22 are funnel-shaped, which can increase the stability of the pipeline 11, so that the iron core will not shake when the iron core is inserted, and the adjusting block 22 can push the limiting block 19 into the inside of the groove 20, enabling the adjusting plate 13 and the pipeline 11 to be movably connected. Under the action of the first spring 18, the piston plate 12 and the adjusting plate 13 move away from each other. At this time, the air inside the pipeline 11 is pushed between the suction cup 10 and the iron core, so that the iron core can be separated from the suction cup 10.

[0044] After separation, the suction cup 10 moves upward to a certain position. The turntable 7 drives the suction cup 10 to rotate. When rotating, the push block 32 contacts the positioning block 29 and pushes the positioning block 29 into the inside of the movable slot 30. At this time, under the action of gravity, the suction cup 10 can fall below the mounting bracket 23, enabling the suction cup 10 to adsorb and pick up the iron core again.

[0045] It should be noted that the number of the suction cups 10 is two groups. When one group of suction cups 10 picks up the iron core, the other group of suction cups 10 can insert the picked-up iron core between the insulating materials 3, which is beneficial to improving the efficiency of iron core lamination.
