Description
The utility model relates to a kind of printed circuit board (PCB) perforation washer, You Zhiqi sends in the body circuit board, through in a row and contain the scavenge pipe top of entire column type scour hole, make it can effectively clear up perforation, or special conductive liquid is carried out in these perforation be attached to operation on the hole wall.
General printed circuit board (PCB) often has the perforation manufacturing procedure during fabrication, for the plant electronic component.Because this type of perforation operation regular meeting produces impurity such as chip, break flour, Copper Foil and is attached to hole wall; if these impurity are not removed fully, easily cause the hole broken or conduct electricity badly, cause follow-up electronic component assembling inconvenience; even be easy to produce defective products thereby the previous operations that must be cleaned.
Clean in the mode in available circuit plate perforation, modal mode is to adopt immersion type, also is about to circuit board and directly soaks and put in treatment fluid, so that the impurity emersion in the perforation is got rid of.But, generally the perforation of this type of printed circuit board (PCB) to run through diameter less, this kind commonly used the poor effect of immersion way.Moreover when carrying out conductive liquid when adhering to perforation, this kind conventional approaches also is unfavorable for carrying out smoothly of this operation.
The purpose of this utility model is providing a kind of clear cleaning to help the printed circuit board (PCB) perforation washer that conductive liquid adheres to, mainly be that groove reaches groove on one in establishing on the body, make down and store the scavenge pipe that soup can be squeezed into groove by air pump in the groove in advance, scavenge pipe is provided with the tiny scour hole of arranging up, and circuit board was transferred by its when top, clear cleaning is convenient in perforation, carries out conductive liquid to be suitable for boring a hole and adheres to operation.
Printed circuit board (PCB) perforation washer of the present utility model, comprise that body, body are provided with the following groove and the conveying device of cleaning soup for putting, it is characterized in that, described groove down is provided with and drives the air pump that cleans soup, following groove top is provided with groove on the plate-like, last groove has scavenge pipe in a row, and scavenge pipe is connected to the trough floor place, and scavenge pipe is provided with the tiny scour hole of entire column type towards the circuit board perforation.
Described printed circuit board (PCB) perforation washer is characterized in that, described scavenge pipe closed at both ends, and its bottom is provided with the cap that is assembled in down trough floor.
Described printed circuit board (PCB) perforation washer is characterized in that described scavenge pipe is positioned at the below of described conveying device bottom roller.
Described printed circuit board (PCB) perforation washer is characterized in that, described air pump comprises a soup master air pump and an anti-precipitation air pump.
Described printed circuit board (PCB) perforation washer is characterized in that, described main air pump is connected at least two control valves that connect scavenge pipe with main an adapter.
Reach embodiment in conjunction with the accompanying drawings, the utility model be described in detail as follows:
Fig. 1: schematic perspective view of the present utility model.
The partial sectional view of Fig. 2: Fig. 1.
Fig. 3: the schematic perspective view of the scavenge pipe in the utility model.
Fig. 4: the utility model flushing action schematic diagram.
Fig. 5: the enlarged diagram before the utility model perforation flushing.
Fig. 6: the schematic diagram that adheres to conductive liquid after cleaning as the perforation among Fig. 5.
As shown in Figure 1, it is the schematic perspective view of a preferred embodiment of the present utility model, and its part, upper left side is analysed and observe.Wherein, body 10 roughly comprises groove 11, for the cleaning soup of deploy suitable height within it, above groove 11 down, then be provided with one be plate-like on groove 20.
Be provided with a main air pump 12 and an anti-precipitation air pump 13 in body 10 fronts, main air pump 12 is with the main a plurality of control valves 15 of 14 connections of taking over.Edge groove 11 1 sides down is provided with a liquid level gauge 16 and a discharge pipe 17.
Please consult Fig. 1,2 simultaneously, last groove 20 surfaces are provided with a plurality of conveying lever groups 21 and the rolling rod group 22 that is provided with in regular turn, for printed circuit board (PCB) 90 is delivered into body 10 inside.Along the biside plate 23 of last groove 20 except that being provided with the elongated slot 24 that power circuit board 90 passes, can find out in side plate 23 partial sectional views as shown in Figure 1, side plate 23 welds together with body 10, and is respectively equipped with return port 25 at the inner bottom surface near biside plate 23, makes soup can be back to down groove 11; Certainly can install soup regeneration reducing device (figure does not show) in the groove 11 down.
Be respectively equipped with scavenge pipe 30 between two rolling rod groups 22, these scavenge pipes 30 can be connected on the base plate of groove 20, and difference connecting branch 40, and 40 of arms are communicated to above-mentioned each corresponding control valve 15.
Now please join Fig. 3, above-mentioned scavenge pipe 30 is made as suitable length, both ends 31,32 sealings, and the bottom in position then is provided with the cap 33,34 of assembling usefulness.Directly over it, then be provided with the scour hole 35 in the intensive tiny aperture of entire column type in a row.As shown in Figure 2, after scavenge pipe 30 entire column type scour hole 35 combinations up, be positioned at the summary below of rolling rod group 22 bottom rollers, it can be aligned by 22 circuit boards that pass through 90 of top roller, so that perforation is washed.
As shown in Figure 4, when circuit board 90 is carried by rolling rod group 22 and advanced to the right side of figure, and after last groove 20 has been sent into soup by main air pump 12 (see figure 1)s, clean soup and will enter scavenge pipe 30 inside, and by 35 ejections of default entire column type scour hole, and in reaching required clean effect at 91 o'clock by circuit board 90 perforation.Itself thus can be as shown in fig. 5, carry out contaminant removal to being positioned at the copper foil layer up and down 92,93 that runs through circuit board 90 and the perforation 91 of main fine plate thereof; Or as shown in Figure 6,91 carry out conductive liquid 94 and adhere to processing boring a hole, this mode adopts another same machine to handle, and changes conductive liquid 94 into but clean soup.
The utlity model has following effect:
Because the utility model in the traveling distance of circuit board, has added air pump, the flushing ability of soup is strengthened, Attachment in the little perforation on the circuit board is washed out by soup, and clean clear, than commonly using printed circuit board (PCB) pair Soaking and washing mode cleaning performance in perforation is good, and can bore a hole by more effective cleaning printed circuit board (PCB), is conducive to lower The carrying out that adheres to together the conduction liquid operation.
