Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 Shown, a kind of glue liquid filtering device comprises stirring tank 1, first diaphragm pump 2, first filter 3, viscosity tank 4, second diaphragm pump 5, second filter 6, backflow filter 7 and backflow diaphragm pump 8,

[0015] The stirring tank 1, the first diaphragm pump 2 communicate, the first filter 3 and the viscosity tank 4 communicate sequentially, the second diaphragm pump 5 communicates with the viscosity tank 4 and the second filter 6, and the second filter 6 communicates with the glue tank 9 ;

[0016] The backflow filter 7 is connected to the glue tank 9, and the backflow diaphragm pump 8 is connected to the viscosity tank 4 and the backflow filter 7; the excess glue in the glue tank 4 passes through the backflow filter 7 to filter the glass wool in the glue, and the filtered The glue is returned to the viscosity tank 4 throug...

Abstract

The invention relates to a glue solution filtering device, which comprises a stirring tank, a first diaphragm pump, a first filter, a viscosity tank, a second diaphragm pump, a second filter, a backflow filter and a backflow diaphragm pump, wherein the stirring tank, the first diaphragm pump, the first filter and the viscosity tank are communicated sequentially, the second diaphragm pump is communicated with the viscosity tank and the second filter, the second filter is communicated with a glue tank; the backflow filter is communicated with the glue tank; the backflow diaphragm pump is communicated with the viscosity tank and the backflow filter; and a viscosity sensor is arranged in the viscosity tank. Due to the adoption of the structure, glue solution is filtered by the filter, so that fillers are dispersed further under the condition that the speed of the fillers is not influenced to solve the problem of filler agglomeration, pipelines are not blocked any more, and prepreg does not have non-dispersed powder points in appearance.

Description

technical field [0001] The invention relates to a glue liquid filtering device, in particular to a glue liquid filtering device used in the bonding process of circuit boards. Background technique [0002] In the current prior art, when mixing filler-containing glue, the packaged filler is usually unpacked and poured directly into the glue mixing tank, and dispersed with a stirrer. The existing problem is: the filler is easy to agglomerate after entering the mixing tank, which leads to poor dispersion and blockage of the pipeline, and the prepreg produced after gluing has filler powder spots. Contents of the invention [0003] The purpose of the present invention is to provide a glue filtering device, which can improve the dispersion effect of fillers, eliminate agglomerated solid fillers and impurities in the glue, and reduce the defects of filler points on the appearance of prepregs. [0004] The present invention is achieved like this: a kind of glue liquid filtering de...
