Technical Field
[0001] The utility model belongs to the technical field of epoxy resin encapsulant, and particularly relates to a stirring device for epoxy resin encapsulant. Background Technique
[0002] Epoxy resin encapsulant is a plastic material applied in the field of electronic component encapsulation. This material is mainly composed of epoxy resin, curing agent, filler, diluent and other additives. At present, when processing it, a special stirring device for epoxy resin encapsulant is usually adopted;
[0003] The existing stirring devices for epoxy resin encapsulant usually use a motor as the driving source during operation, and drive a set of stirring structures or multiple sets of stirring structures to rotate in cooperation with each other to stir the epoxy resin encapsulant. Although the stirring operation of the epoxy resin encapsulant can be realized, there are still some problems in actual use. During the mixing process of the epoxy resin encapsulant, the relative positions of its stirring devices are fixed. Although there are also those that can move up and down by means of a lifting structure, the stirring range is still relatively limited. For example, the epoxy resin encapsulant at the corners of the tank body mostly relies on the flowing epoxy resin encapsulant to drive, which is not conducive to the full agitation and mixing of the epoxy resin encapsulant. Secondly, in the case of such unsatisfactory stirring effect, the phenomenon of material adhesion to the bottom of the tank is likely to occur. Content of the Utility Model
[0004] In view of this, the utility model provides a stirring device for epoxy resin encapsulant, which can effectively eliminate possible stirring dead corners through a stirring mechanism, realize all-round and high-efficiency mixing and stirring of the epoxy resin encapsulant, greatly improve the overall quality and working efficiency of stirring, can deeply stir the epoxy resin encapsulant at all levels comprehensively and deeply, significantly improve the efficiency and quality of stirring, effectively prevent the material from adhering to the bottom of the tank during the stirring process, and ensure that the stirring process is more thorough and uniform.

[0025] The working principle of a stirring device for epoxy resin encapsulant provided by the present utility model is as follows: First, relevant staff feed an appropriate amount of epoxy resin encapsulant into the interior of the stirring tank 100. Then, the relevant staff regulate the operation of the motor 305 and the heating wire 200 through an external single-chip microcomputer.
