Description

Technical Field

[0001] The utility model relates to the technical field of copper foil strip winding auxiliary devices, in particular to a winding auxiliary device for copper foil strips. Background Technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Among them, copper foil strips are essential in the production of transformers. Before the production of transformers, normal copper foil strips are stored in the form of rolls of paper. When winding the copper foil strip, the existing method generally fixes the copper foil strip by using tape or by opening a card slot on the side of the winding shaft. The effect of fixing with tape is not good, and it is not convenient to operate and time-consuming when the card slot is used to snap the copper foil strip inward. Moreover, after the winding is completed, the existing winding shafts are generally provided with limit plates on both sides to play a limiting role by means of clamping or fixing. This makes it inconvenient to disassemble the wound copper foil strip roll. Therefore, we propose a winding auxiliary device for copper foil strips. Summary of the Utility Model

[0014] Beneficial effects

[0015] The utility model provides a copper foil winding auxiliary device, which has the following beneficial effects:

[0016] (1) The copper foil strip winding auxiliary device is provided with a limit module. The first electric push rod pushes the mounting block to move inside the mounting cavity. The mounting block drives the rack to engage with the driving gear so that the limit plate rotates ninety degrees inside the storage cavity. The constraint rod slides inside the constraint groove to constrain the sliding path of the mounting block. The driving motor drives the winding shaft to rotate to wind the copper foil strip. The limit plate constrains the copper foil strip. After the winding is completed, the first electric push rod pulls the mounting block to move back. Under the engagement of the rack and the driving gear, the limit plate is reset and retracted to the position inside the storage cavity. The rolled copper foil strip can be directly removed manually without manually removing the limit plate, which facilitates the unloading of the copper foil strip.

[0017] (2) The winding auxiliary device for the copper foil strip, by setting an auxiliary module, the limiting plate is swung out of the internal position of the storage cavity, the cut copper foil strip is placed at the matching groove position on the side of the winding shaft, the second electric push rod pushes the slider to slide inside the sliding groove, and then the limiting rod slides inside the limiting groove. The limiting rod restricts the driving movable block to slide on the side of the movable groove, and the movable block is extruded and guided by the movable groove to slide out of the internal position of the movable block, so that the matching block presses on the side of the copper foil strip to make it snap into the internal position of the matching groove. In this way, the copper foil strip is snapped onto the side of the winding shaft. After the copper foil strip is fixed, the winding operation is carried out, which facilitates the fixation of the copper foil strip before winding. Description of the Drawings

[0032] The working principle of the present utility model:

[0033] When in use, the first electric push rod 4 pushes the mounting block 5 to move inside the mounting cavity 3. The mounting block 5 drives the rack 9 to engage with the driving gear 8, causing the limit plate 7 to rotate accordingly. Under the action of the rotating shaft of the limit plate 7, it rotates by 90 degrees inside the storage cavity 6. At the same time, the limit block 10 fits and slides on the inner wall of the mounting cavity 3 to restrict the sliding path of the mounting block 5. The constraint rod 12 slides inside the constraint groove 11 to guide and restrict the limit block 10, further restricting the sliding path of the mounting block 5, ensuring that the rack 9 and the driving gear 8 can be fully engaged. The driving motor 2 drives the take-up reel 1 to rotate to wind up the copper foil tape. The limit plate 7 plays a role in limiting and constraining the copper foil tape. After the winding is completed, the first electric push rod 4 pulls the mounting block 5 to move back. Under the engagement of the rack 9 and the driving gear 8, the limit plate 7 is reset and retracted to the position inside the storage cavity 6, facilitating the operator to directly remove the wound copper foil tape roll.

[0034] During use, after removing the copper foil tape roll, the limiting plate 7 is swung out of the internal position of the storage cavity 6, and the cut copper foil tape is placed at the position of the fitting groove 13 on the side of the winding shaft 1. The second electric push rod 20 is controlled to push the slider 19 to slide inside the sliding groove 15. Subsequently, the limiting rod 22 slides inside the limiting groove 21 to squeeze the return spring 23 and is restricted by the connecting groove 16. At the same time, the limiting rod 22 restricts the driving movable block 17 to slide on the side of the movable groove 14. The movable block 17 is squeezed and guided by the movable groove 14 to slide out of the internal position of the movable block 17, so that the fitting block 18 squeezes against the side of the copper foil tape to make it snap into the internal position of the fitting groove 13. In this way, the copper foil tape is snapped onto the side of the winding shaft 1, which facilitates the fixing of the copper foil tape for winding operation.
