Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency transformer core pretreatment, and in particular relates to a high-frequency transformer core side column glue dispensing device. Background Art

[0002] High-frequency transformers are widely used in all walks of life. Generally speaking, the basic structure of a high-frequency transformer includes a magnetic core, a main coil (high-voltage side), a secondary coil (low-voltage side), an insulating material, and a shell. It can convert the input AC power into the required output high and low voltages or currents. It has obvious advantages such as small size, high efficiency, and fast response speed. It is widely used in many industries and fields of national production. Most of the magnetic cores of high-frequency transformers are divided into two parts (planar magnetic core and polished magnetic core), each of which has three core columns (the middle core column is referred to as the middle column, and the core columns on the left and right sides are collectively referred to as side columns). In actual production, electronic glue is usually applied, sprayed, dripped, or filled on the middle column or side column of the magnetic core by manual methods to achieve the functions of fixing, bonding, insulation, and smooth surface of the upper and lower parts of the magnetic core. However, there are problems such as low processing efficiency, poor placement positioning, and inaccurate core fixing, which greatly affect the performance and efficacy of the high-frequency transformer such as inductance.

[0003] Compared with other dispensing forms, the dispensing of magnetic core side columns has the advantages of easy positioning and large working end area, and is a dispensing process that is widely used in the production process of high-frequency transformers. Dispensing of magnetic core side columns is to dispense glue on the side column end faces of the magnetic core at the same time, and the consistency of the side column dispensing should be guaranteed. Chinese patent CN202022934693.5 discloses a magnetic core glue coating machine with an automatic feeding mechanism, but because of the use of a dispensing machine (valve) for dispensing, there are problems such as different amounts of glue on the side columns and poor consistency of the dispensing effect; Chinese patent CN202123091048.2 discloses a magnetic core bonding tool, which can be applied in the form of a printed screen, and the dispensing efficiency is greatly improved, but there are still problems such as easy clogging of the mesh and leakage of glue at the point. Therefore, it can not only ensure the consistency and efficiency of the dispensing of the side columns of the magnetic core of the high-frequency transformer, but also reduce the failure rate and operation and maintenance costs of the dispensing equipment, and then form a general equipment that can be promoted on a large scale, which has become a technical research work urgently needed in the field of dispensing of the side columns of the magnetic core of the high-frequency transformer.
