Abstract
The utility model relates to a secondary group air knife of a horizontal tin sprayer. The outlet of a whole machine is provided with an upright main shaft. One side of a main shaft is provided with a reinforcing sheet and is transversally provided with a supporting sheet. Both sides of the lower side the supporting sheet are respectively and downwards provided with a side sheet. The outer part of the side sheet is provided with an angular adjustment plate of an air knife with an arc-shaped hole. The outer side of the angular adjustment plate is provided with an adjustment arm of the air knife. Two through holes through which an adjustment rod of the air knife can be transversally penetrated are respectively formed on the angular adjustment plate. A bottom between two side sheets is transversally provided with an upper air knife. A lower knife is correspondingly arranged under the upper air knife. Thereby, a tin bridge (wire) left after a first group air knife blows a print circuit plate is completely eliminated by the secondary group air knife.
Description
The utility model relates to a kind of horizontal tin-spraying machine, the second group of air knife that particularly relates to a kind of horizontal tin-spraying machine, eliminate fully with the remaining Xi Qiao that gets off (silk) after first group of air knife being blown over printed circuit board (PCB) with second group of air knife, can prevent short circuit phenomenon thus.
The use of horizontal tin-spraying machine has closely bound up with inseparable relation for the manufacturer who is engaged in printed circuit board (PCB), horizontal tin-spraying machine can not explained so the practicality of horizontal tin-spraying machine is not sayed for the usefulness of spray tin on the printed circuit board (PCB).
But, general traditional horizontal tin-spraying machine, because of printed circuit board (PCB) essential tin stove of going up after electroplating, after two contacts on the circuit in the printed circuit board (PCB) are through the tin stove, make most probably between two contacts because of producing the bad phenomenon that Xi Qiao (silk) causes short circuit, so general dealer is positioned over one with the printed circuit board (PCB) behind the last tin stove to be full of in the glycerine groove of " glycerine ", obstruct the formation of Xi Qiao (silk) on the printed circuit board (PCB) with glycerine, but glycerine not only purchase cost is quite high, and also can produce the environmental issue of contaminated environment, so form this problem of Xi Qiao (silk), be not to be a kind of good plan for solving on the printed circuit board (PCB).
Also has a kind of traditional structure in addition, it only is in being provided with merely on the horizontal tin-spraying machine on one group, following air knife, when printed circuit board (PCB) in through after the tin stove, tend on printed circuit board (PCB), speckle with metallic tin, form Xi Qiao (silk) and make between two contacts of circuit on the printed circuit board (PCB) because of metallic tin, the main effect of this group air knife only is can the tin face on the printed circuit board (PCB) be flattened, on this, the design principle of following air knife is to make wind-force greater than the plumbous cohesive force of tin, and less than the interfacial force between the copper tin, drive away Xi Qiao (silk) in view of the above, but, often can't utilize on existing one group because the quantity of Xi Qiao (silk) is too much, following air knife is once promptly effectively eliminated Xi Qiao (silk).
Main purpose of the present utility model is to provide a kind of second group of air knife can eliminating the horizontal tin-spraying machine of remaining tin silk fully.
For achieving the above object, the utility model is taked following scheme:
Second group of air knife of horizontal tin-spraying machine of the present utility model is characterized in that, comprising:
Each vertically is provided with a lateral plate up with spacing distance in both sides above the body seat of honour in horizontal tin-spraying machine exit, is set with one for the following air knife that blows printed circuit board (PCB) up between the inboard of two lateral plates top;
Vertically be provided with an air knife angle adjustment plate outside the lateral plate in the outside above last air knife, be formed with arcuate socket and axis hole on it respectively, air knife is set between one group of relative axis hole;
Be provided with an air knife in the outside of each lateral plate and adjust arm, adjust on the arm in air knife and be formed with two perforations respectively, mat one air knife adjusting lever laterally wears after air knife adjusts in the arcuate socket of perforation on the arm and air knife angle adjustment plate, locks with nut in the lateral plate inboard again.
Second group of air knife of described horizontal tin-spraying machine, it is characterized in that, described upper and lower air knife is made up of the two-chip type air knife, respectively form an opening in air knife top, bottom, described opening can be for connecting the pipeline with gas, gas charges into opening, in opening top down, the top extended to form passage so that gas through passage down, the top is circulated to the upper and lower side of upper and lower air knife.
Second group of air knife of described horizontal tin-spraying machine, it is characterized in that, side in the described body seat of honour is provided with a vertical shaft holder, in the inner upper and lower vertical shaft that wears of vertical shaft holder, described vertical shaft is in the inner pivot of vertical shaft holder, side in the vertical shaft top is provided with a reinforcing chip, and the side of reinforcing chip is provided with a support chip, in the both sides of support chip below one lateral plate is set down respectively.
Compared with the prior art the utility model has following effect:
Left Xi Qiao (silk) eliminated fully after the utility model can be blown over first group of air knife printed circuit board (PCB) with second group of air knife, and the effect of second group of air knife is to utilize air knife that the remaining tin lead of part is come back the origin-location and unlikely formation Xi Qiao (silk), in order to prevent because of Xi Qiao (silk) bad short circuit phenomenon taking place on the printed circuit board (PCB).
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is a front elevational schematic of the present utility model.
Fig. 2 is the partial sectional view of vertical shaft of the present utility model, reinforcing chip, support chip and air knife structure.
Fig. 3 is the sectional view of lateral plate of the present utility model, air knife angle adjustment plate, air knife adjustment arm, air knife adjusting lever.
Fig. 4 is the front view of air knife down of the present utility model.
Fig. 5 is the sectional view of air knife down of the present utility model.
The utility model is a kind of second group of air knife (as shown in Figure 1) of horizontal tin-spraying machine, it mainly is that each vertically is provided with a lateral plate 11 up with spacing distance in the both sides of 10 tops, the body seat of honour in horizontal tin-spraying machine exit, is set with air knife 20, (as shown in Fig. 4,5) between the inboard of two lateral plates, 11 tops;
Following air knife 20 is formed with two-chip type air knife 21, the structure that in Fig. 5, shows monolithic air knife 21, form an opening 22 in the bottom of air knife 21, this opening 22 can be for connecting the pipeline with gas, to allow gas charge in the opening 22, extended to form passage 23 up in opening 22 tops, to allow gas be circulated to down the top of air knife 20 up, for the usefulness that dries up the Xi Qiao (silk) that speckles with on the printed circuit board (PCB) through passage 23;
