Tooling structure for presetting permeability quotient (PQ)-type magnetic cores

Abstract

The invention provides a tooling structure for presetting permeability quotient (PQ)-type magnetic cores, which comprises an upper plate and a lower plate; the upper plate is cut into a plurality of preset areas by tape cutting positioning lines; a penetrated preset hole is arranged on each preset area; and the surface of the lower plate is provided with bosses which correspond to the positions of the preset holes. Both ends of the upper plate and the lower plate are provided with installation holes, the upper plate and the lower plate are connected through screws in the installation holes, and springs are sleeved on the screws between the upper plate and the lower plate. According to the tooling structure for presetting the PQ-type magnetic cores, a plurality of PQ-type magnetic cores to be preset can be fixed at one time when tapes are preset, the magnetic cores do not deviate even if the shapes of the PQ-type magnetic cores are irregular, the tapes are stuck onto the bottoms of the PQ-type magnetic cores at one time, the lengths of the tapes are cut by the tape cutting positioning lines precisely, so that the production efficiency is improved, and the defect rate of products due to the poorness of the preset tapes is reduced.

Description

technical field [0001] The invention relates to a tooling structure, in particular to a tooling structure for presetting adhesive tape on the bottom of a PQ type magnetic core. Background technique [0002] The bottom of the PQ core needs to be wrapped with tape to isolate it from the circuit board. At present, most of the work on PQ magnetic core presetting tapes is done manually. Such as figure 1 , figure 2 As shown, due to the irregular shape of the PQ type magnetic core, the manual presetting of the tape is slow and non-standard, and the manual presetting cannot accurately control the distance from the tape to the foot of the magnetic core after wrapping, resulting in a low defect rate of the magnetic core presetting. high. Contents of the invention [0003] The purpose of the present invention is to provide a PQ type magnetic core preset tooling structure to improve the preset speed and preset standard. [0004] Technical scheme of the present invention is as fo...
