Description

The rectilinear plate wire of PCB and be used for the raffinate collection device of the rectilinear plate wire of PCB

Technical field

The utility model relates to printed substrate (PCB) field, in particular to the rectilinear plate wire of PCB and be used for the raffinate collection device of the rectilinear plate wire of PCB.

Background technology

Fig. 1 shows the synoptic diagram according to the rectilinear plating line of PCB of prior art; Its workflow routine is: upper plate, and---------------pickling---is electroplated---four washings---five washings---six washings---lower plate---strip---seven washings---eight washings---upper plate, so rule circulation to secondary water washing in three washings in inferior washing in oil removing.

This rectilinear plating line is that the groove on the electroplating assembly line comprises processing solution tank and washing bath, should avoid crossed contamination as far as possible.Rectilinear chemical plate wire similarly.

In the production process, overhead traveling crane 12 drives the operation that flies to cling to, and pcb board spare 20 need be fixed on and fly to cling on 10, flies to cling to 10 and drives pcb board spare 20, moves back and forth to satisfy the needs of Production Flow Chart 30 of each grooves.Fly to cling to 10 pcb board spare 20 moved to required each groove 30 top of flow process, fly to cling to 10 and downwards pcb board spare 20 bath verticallies are gone in the liquid medicine, treat pcb board spare 20 after certain groove processing finishes, fly to cling to 10 and mentioned by overhead traveling crane 12.At this moment, residual a large amount of these groove liquid medicine of meeting on pcb board spare 20, and constantly drip.Along with flying to cling to 10 move, remaining liquid medicine can be dropped between groove or bring in other washing baths 30 of flow.

Usually, pcb board spare is flown can stop some times on this groove top earlier, in the return-enclosure of the drippage of the raffinate on the pcb board spare after crust mentions from a cell.If need drip these raffinates fully, meeting consuming time is very long, influence production capacity, so still have the part raffinate to remain on the pcb board spare during common production.

Embodiment

Below with reference to accompanying drawing and combine embodiment, specify the utility model.

Fig. 2 shows the synoptic diagram according to the raffinate collection device of the utility model embodiment; The rectilinear plate wire of PCB comprises: overhead traveling crane 12, cell body (not shown), unit (not shown) and raffinate collection device, and the raffinate collection device comprises: raffinate catch tray 50; Moving structure 60 is loaded to overhead traveling crane 12 with raffinate catch tray 50; Motor 60; Connect moving structure 70; Be used to drive moving structure 70 raffinate catch tray 50 is displaced sideways with respect to overhead traveling crane 12, with below that moves to overhead traveling crane 12 or the below of leaving overhead traveling crane 12, the driving of 60 pairs of moving structures 70 of motor can be adopted modes such as gear, belt; The unit (not shown) connects motor 60, is used to control the work of motor 60.This device relatively simple for structure realized easily.Unit can adopt the work of PLC formula control motor 60

In the prior art of Fig. 1, the raffinate that pcb board spare is enclosed in a cell will directly drop onto in the cell of next flow process, therefore have the problem of crossed contamination, perhaps be dropped in gap between groove, pollute plating line and surrounding working environment.And in the present embodiment; As shown in Figure 1, because being moved structure 70, raffinate catch tray 50 is loaded to overhead traveling crane 12, so when overhead traveling crane 12 moves on each processing solution tank and washing bath along slide rail; Motor 60 can drive the below that raffinate catch tray 50 moves to overhead traveling crane 12; Therefore can collect the raffinate that drips from pcb board spare, thus the crossed contamination of each groove liquid medicine in the production process reduced, and the liquid medicine pollution that has reduced plating line and surrounding working environment.

Preferably, unit comprises: first module is used for drive-motor, so that moving structure moves to the raffinate catch tray below of overhead traveling crane; Second module is used for drive-motor, so that moving structure leaves the raffinate catch tray below of overhead traveling crane.

In the production process, after pcb board spare disposes in certain groove, overhead traveling crane fly Ba Tiqi pcb board spare.At this moment, be sent to pcb board spare bottom through control raffinate catch tray.Afterwards, overhead traveling crane drives pcb board spare and moves to next groove, and raffinate catch tray this moment flies crust with the speed operation with overhead traveling crane, guarantees that it is in pcb board spare bottom all the time, to collect on the pcb board spare plate face the constantly liquid medicine of drippage.The flying of overhead traveling crane removed the raffinate catch tray, when the catch tray area is bigger than normal before crust puts down pcb board spare; Can make it to be in the production line end, when area is less than normal, can directly place overhead traveling crane fly the crust near; So that overhead traveling crane fly crust when pcb board spare mentioned once again from groove, can will coil and move to its time rapidly.But no matter where the raffinate catch tray is only moved to otherwise the conventional production process of influence gets final product.Connection through moving structure; What can make raffinate catch tray and overhead traveling crane flies to cling to same moved further; Drippage is clean thereby pcb board spare need not be waited for raffinate basically, but after a production stage finishes, directly moves to next cell; In moving process, the raffinate catch tray just can be collected the raffinate that drips from pcb board spare.Because reduced the waiting time between each step, so this preferred embodiment has improved the production capacity of the rectilinear plate wire of PCB.

Fig. 4 shows the synoptic diagram according to the raffinate catch tray of another preferred embodiment of the utility model, and raffinate catch tray 50 comprises: disk body 52, and the disk body width is not less than the width of groove 30, and its bottom has the funnel shaped that is used for liquid collecting, and funnel bottom has liquid-leaking nozzle; Liquid discharge pipe 54, one ends are communicated with the liquid-leaking nozzle of disk body 52 bottoms, and the other end reaches the outside of groove 30; Be collected in the special raffinate container; Perhaps extend the top of last cell backward, so that the low raffinate of pcb board spare can be back to rapidly in the last cell, but the former more can avoid crossed contamination.The discharge opeing effect of the raffinate catch tray 50 of Fig. 4 is superior to the discharge opeing effect of the raffinate catch tray 50 of Fig. 3.

Preferably, the raffinate catch tray is organic polymer plastics or the stainless steel of acid and alkali-resistance or the catch tray that PVC processes.This can prolong the work-ing life of raffinate catch tray 50.

Preferably, the rectilinear plate wire of PCB is upright plating line or vertical chemical plate wire.On the upright plating line or on the vertical chemical plate wire raffinate collection device of the foregoing description can be installed, thereby improve electroplating effect or electroless plating effect.

Can find out that from above description the utility model the above embodiments have the following advantages:

1, reducing pcb board spare drips this troughed belt and goes out the required residence time of liquid medicine on groove;

2, reduce the crossed contamination of liquid medicine between each groove;

3, prevent that PCB from going up remaining liquid medicine and being dropped in the gap between the groove, pollute production line and surrounding working environment;

4, increase the raffinate catch tray after, fly crust and can drive pcb board spare and on production line, arbitrarily move, and can not pollute each groove because of the liquid medicine of drippage.Possibility combined segment washing bath shortens production line length like this, reduces space hold.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
