[0001] The utility model relates to the technical field of transformers, in particular to a pin placement machine for a transformer. Background Technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its components include a primary coil, a secondary coil, an iron core, pins, etc. The pins of the transformer are low in thickness and large in number. After being batch extruded and leveled by a mold, they need to be taken out one by one. The pins in the transformer are connected to the power supply or the load, and the pins are mainly made of aluminum materials. During the production process of the transformer, the pins need to be placed on a placement machine for use.

[0003] For example, a pin leveling machine for a transformer with the Chinese patent application number CN201821691867.6 can be used to place the pins. It includes a bottom plate and a top plate located at the top of the bottom plate. Two corners on one side of the top of the bottom plate are fixedly provided with support columns, and the top of the top plate is fixedly connected to the top of the support columns.

[0026] By setting the placement component 2, the staff can hold the handle 26 and drive the top cover 25 to flip, and sequentially place the pins of the transformer to be placed between each V-shaped rubber pad 24 in the placement cavity 22, so that the V-shaped rubber pad 24 protects between two adjacent transformer pins, avoiding mutual wear of the transformer pins when handling the L-shaped base 1, ensuring the integrity of the transformer pins, and improving the placement effect.

[0027] As Figures 1-4 shown, an elastic pressing component 3 is provided inside the L-shaped base 1 to facilitate the automatic extraction of the pins of the transformer placed inside the placement component 2. The elastic pressing component 3 includes a balance rod 31. A driving cavity 5 is formed inside the L-shaped base 1. A fixed rod 35 is fixedly provided between the front and rear side walls on one side inside the driving cavity 5. The balance rod 31 is rotatably arranged on the fixed rod 35.
