Abstract
The utility model discloses a kind of pcb board and electroplate jet pipe protection structure; it comprises that bottom is provided with the plating cylinder groove of pontoon bridge; the both sides of this plating cylinder groove arrange respectively liquid medicine circulation jet pipe; this liquid medicine circulation jet pipe is provided with a plurality of liquid medicine nozzles; each liquid medicine nozzle periphery arranges protecting sheet, and this protecting sheet is provided with the through hole corresponding with the spout of this liquid medicine nozzle.This protecting sheet is arranged on this liquid medicine circulation jet pipe, and parallel with the orientation of a plurality of these liquid medicine nozzles, and a plurality of liquid medicine nozzles wrap in the bearer bar of being located at this protecting sheet formation together.The utility model has solved in process of production, because being subject to pcb board pendulum impact to the nozzle of liquid medicine circulation jet pipe, and makes liquid medicine nozzle variant, comes off, and causes liquid medicine spray to press lower, the hidden danger of quality of pcb board covering power deficiency.
Description
Technical field
The utility model relates to pcb board manufacture processing, particularly the protection structure of pcb board plating line liquid medicine circulation jet pipe.
Background technology
As shown in Figure 1, the electroplating processing process of pcb board, to clamp pcb board 3 by flying to cling to 6, vertical extension hangs in plating cylinder groove 2, respectively there is a drug row water cycle jet pipe 4 both sides of electroplating cylinder groove 2, the nozzle 5 of two drug row water cycle jet pipes 4 is relative, electroplates, and guarantee the covering power of plating to working the pcb board 3 fall between the two drug row water cycle jet pipes 4 spray medicine that pressurize.In pcb board 3 bottoms, pontoon bridge 1 is set, pcb board 3 is had to the upwards pressure on top simultaneously.Drive pcb board to vacillate now to the left, now to the right in process flying bar; the upwards pressure on top because of pontoon bridge; make the swing frequency of pcb board keep unanimous between the higher and lower levels; but due to the thickness of pcb board and the reason of length; conventionally in the middle of the amplitude of fluctuation of pcb board, is greater than upper and lower two ends, thereby in swing, often can touches nozzle when thickness of slab thinner (being less than 0.5mm) (be generally that PCB product size is grown (being greater than 600mm), or) of both sides in processing solution tank groove cylinder; if things go on like this, therefore nozzle touches curved severing most probably.Therefore, in production, need carry out regular inspection to the nozzle of each groove section, find the nozzle distortion that comes off, need to shut down and change in time, as discovery not in time, cause most probably some quality problem.How avoiding pcb board collision or protection nozzle not to be subject to collision is the fundamental means addressing the above problem.
Due to waving of pcb board, effect is to increase the covering power of liquid medicine in hole, therefore, cancel and wave or rocking tendency is reduced, can affect the covering power of holes of products copper, affect product quality, if widen the horizontal throw of nozzle and pcb board, avoid collision, on the one hand, the groove cylinder width of equipment is fixed, can not widen, on the other hand, widen the horizontal throw of nozzle and pcb board, the spray that can affect liquid medicine circulation is pressed, and affects equally the covering power in PCB hole.Above approach, all passes through a lot of practices and theoretical analysis and proves failure and impracticable.
Utility model content
Technical problem to be solved in the utility model is; not enough for prior art; provide a kind of can be in process of production; avoid pcb board pendulum impact to the nozzle of liquid medicine circulation jet pipe; and make liquid medicine nozzle variant; come off, cause liquid medicine spray to press lower, the pcb board of pcb board covering power deficiency is electroplated jet pipe protection structure.
For addressing the above problem; the technical solution adopted in the utility model is; a kind of pcb board is electroplated jet pipe protection structure; it comprises that bottom is provided with the plating cylinder groove of pontoon bridge; the both sides of this plating cylinder groove arrange respectively liquid medicine circulation jet pipe; this liquid medicine circulation jet pipe is provided with a plurality of liquid medicine nozzles, and each liquid medicine nozzle periphery arranges protecting sheet, and this protecting sheet is provided with the through hole corresponding with the spout of this liquid medicine nozzle.
Further being improved to of such scheme, this protecting sheet is arranged on this liquid medicine circulation jet pipe, and parallel with the orientation of a plurality of these liquid medicine nozzles, and a plurality of liquid medicine nozzles wrap in the bearer bar of being located at this protecting sheet formation together.
Further being improved to of such scheme, the height of this protecting sheet is greater than height 3 mm of this liquid medicine nozzle.
The utility model arranges protecting sheet in the liquid medicine nozzle periphery of electroplating cylinder groove; and protecting sheet is provided with the through hole corresponding with the spout of this liquid medicine nozzle; so not only liquid medicine can normally spray pcb board is electroplated; and when pcb board is when production process swings, at most only can bump against protecting sheet, and can not bump against nozzle; make liquid medicine nozzle can not produce distortion because of collision; come off, more can therefore not cause liquid medicine spray to press lower, pcb board covering power be not enough.In addition, because protecting sheet, by being welded and fixed, can tolerate multiple impacts.

Embodiment
As shown in Figure 2; the utility model pcb board is electroplated jet pipe protection structure; comprise that bottom is provided with the plating cylinder groove 2 of pontoon bridge 1; the both sides of this plating cylinder groove 2 arrange respectively liquid medicine circulation jet pipe 4; this liquid medicine circulation jet pipe 4 is provided with a plurality of liquid medicine nozzles 5; each liquid medicine nozzle 5 periphery arranges protecting sheet 7, and this protecting sheet 7 is provided with the through hole corresponding with the spout of this liquid medicine nozzle 58.
Of the present utility model one is preferably, and this protecting sheet 7 is fixedly installed on this liquid medicine circulation jet pipe 4, and parallel with the orientation of a plurality of these liquid medicine nozzles 5, and a plurality of liquid medicine nozzles 5 are besieged being arranged in the bearer bar that this protecting sheet 7 forms together.
Of the present utility model one is preferably, and the height of this protecting sheet 7 is greater than height 3 mm of this liquid medicine nozzle 5.
