The device can 100% avoid the hole-plugging problems of the non-woven brush wheels and grinding materials of a printed wiring board, and can improve the qualification rate of the circuit board by 1-2%. Furthermore, the structure needs few apparatuses, and is conveniently operated and controlled; and the device is suitable for widely popularizing.
Description
Technical field
The utility model relates to a kind of device that prevents flash trimmer bristle plug-hole.
Background technology
That generally uses in the wiring board process of each wiring board producer before handling boring back electroless copper plating now is the adhesive-bonded fabric brush plate machine, the brush wheel material is an adhesive-bonded fabric, wiring board boring metapore edge inevitably more or less have a burr, this burr is mainly more sharp-pointed copper, the adhesive-bonded fabric brush wheel is in the process of the high speed polish-brush wiring board of 1800-2000r/min, adhesive-bonded fabric and abrasive material can be by sharp-pointed copper (capillary copper thorns, the copper burr) cuts away and be scattered on the PCB surface, these adhesive-bonded fabrics and abrasive material slag be not as being washed timely, can in follow-up brush wheel polish-brush process, be expressed in the hole of wiring board with solid setting-out roller, cause bristle plug-hole problem, though each adhesive-bonded fabric brush wheel all has the cooling water flushing, these water yields and eruption mode can not rinse out the adhesive-bonded fabric residue and the abrasive material slag that produce effectively and timely; The brush wheel that all deserves to be called brand as industry that we use as 3M, field, Japanese angle, but all can not be avoided the problem of bristle plug-hole; The diameter that Kong Youyi the general characteristics that the plug-hole problem takes place are these holes more than 90% all between φ 0.3-0.4mm, analyzes former because of the bristle diameter that is cut close with bore dia due to.
Summary of the invention
The utility model is at the proposition of above problem, and develops a kind of device that prevents flash trimmer bristle plug-hole.The technological means that the utility model adopts is as follows:
A kind of device that prevents flash trimmer bristle plug-hole is characterized in that comprising: stainless steel leads directly to nozzle, circulating pump, filter and connecting line; The straight-through nozzle of described stainless steel is fixed in the two the angle of adhesive-bonded fabric brush wheel and wiring board, and its nozzle direction is parallel to the in-plane of adhesive-bonded fabric brush wheel and wiring board; Described circulating pump is drawn the water in the aqua storage tank through connecting line, through being communicated on the straight-through nozzle of stainless steel by connecting line behind the filter.
The straight-through nozzle lower edge of described stainless steel is apart from wiring board upper surface 4-6mm, and left hand edge is apart from adhesive-bonded fabric brush wheel center line 80-90mm, and the straight-through nozzle vertical direction of stainless steel is concordant with the wiring board edge.
The straight-through nozzle of described stainless steel is fixed on the cell wall of existing equipment by connecting line.
The straight-through nozzle of described stainless steel only is installed in the last brush place of adhesive-bonded fabric brush plate machine.
The beneficial effects of the utility model are:
1, adhesive-bonded fabric bristle and the abrasive material plug-hole problem of can 100% avoiding printed substrate improve wiring board qualification rate 1-2%.
2, the running water behind the circulating filtration of this structure use adhesive-bonded fabric brush wheel can not increase extra water consumption, the conserve water resource.
3, this structure equipment needed thereby seldom, fitting operation, control very easy.

Among the figure: 1, adhesive-bonded fabric brush wheel, 2, the stainless steel counter-pressure cylinder, 3, the brush wheel cooling water nozzle, 4, transfer roller/squeeze roll(s), 5, the brush wheel cooling water, 6, the straight-through nozzle of stainless steel, 7, impact to clean current, 8, adhesive-bonded fabric bristle and abrasive material, 9, wiring board, 10, through hole, 11, connecting line, 12, circulating pump, 13, filter, 14, overflow passage, 15, Copper Filter, 16, one-level aqua storage tank, 17, the secondary aqua storage tank, 18, lower face adhesive-bonded fabric bristle and abrasive material
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, can prevent the device of flash trimmer bristle plug-hole, selecting nozzle diameter is the straight-through nozzle 6 of stainless steel of φ 5mm, is fixed in the two the angle of adhesive-bonded fabric brush wheel 1 and wiring board 9, and its nozzle direction is parallel to the in-plane of adhesive-bonded fabric brush wheel 1 and wiring board 9; The utility model is to be fixed on the cell wall of existing equipment by connecting line, and straight-through nozzle 6 lower edges of stainless steel are apart from wiring board 9 upper surface 4-6mm, and left hand edge is apart from adhesive-bonded fabric brush wheel 1 center line 80-90mm, and the spout vertical direction is concordant with wiring board 9 edges.The utility model is to draw pipeline from the secondary aqua storage tank 17 of flash trimmer to connect a circulating pump 12, connect a cotton filter 13 behind the circulating pump 12, the cotton core specification is selected 50-100 μ m for use, filter 13 outlets connect connecting line 11 and receive on the straight-through nozzle 6 of stainless steel always, above structure will guarantee that the straight-through nozzle 6 of stainless steel can spray the discharge of 40-50L/min, this discharge forms the impact cleaning current 7 of wide 10-20mm together at the upper surface of wiring board 9 along adhesive-bonded fabric brush wheel 1 direction, this impacts cleaning current 7 and can be flushed to adhesive-bonded fabric bristle that is cut away by circuit plate hole burr and abrasive material 8 timely in the following tank, avoid at wiring board during through the transfer roller/squeeze roll(s) 4 of back and adhesive-bonded fabric brush wheel 1 and stainless steel counter-pressure cylinder 2, these adhesive-bonded fabric bristles and abrasive material 8 are pressed in the through hole 10 of wiring board 9, cause the plug-hole problem.Falling into adhesive-bonded fabric bristle in the following tank and abrasive material 8 can be pumped to Copper Filter 15 by overflow passage 14 and filter out, filtered running water enters one-level aqua storage tank 16, enter secondary aqua storage tank 17 after filtering through screen pack again, water in the secondary aqua storage tank 17 is being sprayed onto on wiring board 8 surfaces by the straight-through nozzle 6 of stainless steel by circulating pump 12 and cotton filter 13, so circulation, as shown in Figure 1 and Figure 2; The adhesive-bonded fabric brush plate machine generally has 2-4 group adhesive-bonded fabric brush wheel 1, every group of adhesive-bonded fabric brush wheel gone up brush and following brush in 1 minute, the next door that we only brush on each increases straight-through nozzle 6 structures of this stainless steel, following brush next door is that the lower surface of wiring board 9 need not increase, because the lower surface of wiring board 9 is behind brush board, lower face adhesive-bonded fabric bristle that is cut and abrasive material 18 can be under the effects of brush wheel cooling water nozzle 3,5 effects of brush wheel rinse water and gravity, drop voluntarily below in the tank, can not adhere on wiring board 9 surfaces, as shown in Figure 3.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection range of the present utility model.
