Problems solved by technology

The non-woven brush wheel made in this way will cause inconsistent glue concentration ratio inside and outside the brush wheel, poor air permeability, and impermeability of impregnated glue
As a result, the grinding force of the non-woven brush wheel is low, the grinding uniformity is poor, and the service life of the brush wheel is short.
Especially for grinding and removing resin plug holes, the above-mentioned non-woven brush wheels have disadvantages such as low grinding and cutting force, uneven grinding, and short service life.
In this way, the common PCB will cause a lot of quality scrap, and the production efficiency is low, which is not conducive to production

Embodiment 1

[0024] Embodiment 1: as figure 2 As shown, a non-woven brush wheel includes an axis 7 and a non-woven layer 8 wound on the axis and composed of multiple layers of non-woven fabrics. It is characterized in that the non-woven layer 8 is wound on the Obtained on axis 7.

[0025] In this embodiment, the axis 7 is a phenolic paper-based bakelite tube, the non-woven fabric is a non-woven fabric containing abrasives, so that the non-woven fabric brush wheel has better friction, and the glue is composed of resin glue: acetic acid Ethyl ester: formulated with a surfactant; the resin glue is phenolic resin glue, water-based polyurethane resin, or one of other epoxy resins, PU foaming resins, acrylic resins, and melamine resins , or a combination of the above-mentioned various resin glues; the surfactant is one of anionic surfactants, cationic surfactants or nonionic surfactants.

Embodiment 2

[0026] Embodiment 2: as figure 1 As shown, a production system for non-woven brush wheels, including a feeding unit for inputting non-woven fabrics, a dipping unit for dipping non-woven fabrics and a non-woven fabric for winding the dipped non-woven fabrics into dense non-woven fabrics arranged in sequence Winding unit for rolls.

[0027] In this embodiment, the feeding unit includes a first upper roller 1 and a first lower roller 2 arranged up and down, and between the first upper roller 1 and the second upper roller 2 is a supply The non-woven fabric passes through the gap, and the two sides of the surface of the non-woven fabric rub against the upper and lower rollers to move forward, thus completing the feeding of the non-woven fabric. In this embodiment, the feeding unit is not limited to the above-mentioned scheme, and a conveyor belt can also be used and a roller is arranged above the conveyor belt. There is a gap for the non-woven fabric to pass between the conveyor b...

Embodiment 3

[0031] Embodiment 3: a kind of production method of non-woven cloth brush wheel, it adopts a kind of production system of non-woven cloth brush wheel to implement, and its steps are:

[0032] 1) Start the winding machine to rotate the winding roller, and the non-woven fabric enters the feeding unit, which is smoothed by the feeding unit and transported to the dipping unit;

[0033] 2) The non-woven fabric enters the dipping tank and is placed under the pressure roller. Under the pressure exerted by the pressure roller, the non-woven fabric is completely submerged in the prepared glue;

[0034] 3) The dipped non-woven fabric enters the extrusion unit, and the excess glue is squeezed out under the pressure exerted by the second upper roller and the second lower roller;

[0035] 4) The non-woven fabric is wound on the upper axis layer by layer through the rotation of the winding roller to form a non-woven fabric brush wheel;

[0036] 5) Shake the glue with the rolled brush wheel...

Abstract

The invention belongs to the field of PCB cutting, and discloses a non-woven fabric brush wheel as well as a production system and method thereof. The non-woven fabric brush wheel comprises an axis and a non-woven fabric layer which is wound on the axis and is formed by a plurality of layers of non-woven fabrics. The non-woven fabric brush wheel is characterized in that the non-woven fabric layeris formed by a non-woven fabric wound on the axis after being impregnated. The production system for the non-woven fabric brush wheel comprises a feeding unit for inputting the non-woven fabric, an impregnating unit for impregnating non-woven fabric and a rolling unit for rolling impregnated non-woven fabric into a compact non-woven fabric roll, and the feeding unit, the impregnating unit and therolling unit are sequentially arranged. The invention aims to provide the non-woven fabric brush wheel. The non-woven fabric brush wheel is high in hardness, is uniform in glue content, is good in grinding effect and is long in service life. The invention further discloses the production system and the production method for the non-woven fabric brush wheel.

Description

technical field [0001] The invention relates to the field of PCB board manufacturing tools, in particular to a non-woven brush wheel and its production system and method. Background technique [0002] As we all know, the non-woven brush wheels for PCB grinding on the market, whether it is a coiled non-woven brush wheel, a radial non-woven brush wheel, or a disc-shaped non-woven brush wheel, first fix the non-woven fabric into a cylindrical structure. Then remove the impregnated resin (the concentration ratio of the impregnated resin and glue should not be too large, otherwise the brush wheel may not be impregnated), and fix the brush wheel into shape. The non-woven brush wheel made in this way will cause inconsistent glue concentration ratio inside and outside the brush wheel, poor air permeability, and impermeability of impregnated glue. As a result, the grinding force of the non-woven brush wheel is low, the grinding uniformity is poor, and the life of the brush wheel is ...
