Description

Technical Field

[0001] The utility model relates to the technical field of transformer skeleton processing, in particular to a deburring processing device for a transformer skeleton. Background Art

[0002] As described in the published patent CN207509040U, "switching transformer" generally refers to the transformer used in "switching power supply", which works in a pulse state of a frequency of tens to tens of kilohertz or even hundreds of kilohertz, and the core is generally made of ferrite material. The existing switching transformer skeleton is prone to burrs during the production process, and the staff often removes the burrs manually in the later processing. This operation method is time-consuming and labor-intensive, and is prone to omissions, resulting in substandard product quality.

[0003] As described in the published patent CN211916555U, a switching transformer refers to a transformer used in a switching power supply. One of the main components of a switching transformer is the skeleton. The skeleton will produce a lot of burrs during the production process. During processing, the burrs need to be removed to improve the appearance quality of the product. There are currently two ways to remove skeleton burrs. One is manual deburring by grinding with a grinding wheel, and the other is to remove burrs using the principle of sandblasting. The first method is time-consuming and labor-intensive, and the product qualification rate is low, while sandblasting deburring has a high degree of mechanization and a relatively high product qualification rate.

[0004] Patent CN207509040U discloses a sandblasting switch transformer frame deburring device, in which the product is placed on a conveyor belt, and a sandblasting head is arranged above the conveyor belt. Driven by the conveyor belt, the product flips under the sandblasting head, and the metal sand sprayed by the sandblasting head polishes the burrs on the product. The deburring device of this patent improves the efficiency and quality of deburring the transformer frame, and facilitates batch removal of burrs. When in this device, after each burr grinding, the staff needs to take the products out of the conveyor belt one by one, which is not convenient for discharging, and the time interval between two batches of grinding is extended, and the overall efficiency is low.

[0005] In summary, in the prior art, the switching transformer skeleton has a low pass rate during the burr removal process. Utility Model Content
