Alcohol rinse bath, is connected with the described trichloro-ethylene rinse bath of right-hand member;
Supersonic generator, is arranged on described in each in trichloro-ethylene rinse bath and described alcohol rinse bath;
The groove of heating, is arranged on described in each in trichloro-ethylene rinse bath and described alcohol rinse bath; And
Automatic delivering mechanism, across the top at described trichloro-ethylene rinse bath and described alcohol rinse bath.
The utility model is provided with cooling-part in described cleaning fluid recovering mechanism, between the described trichloro-ethylene rinse bath of described cleaning fluid recovering mechanism and right-hand member, is connected to mozzle; Between described mozzle and described cleaning fluid recovering mechanism, be provided with to the check valve of described mozzle direction circulation, between the described trichloro-ethylene rinse bath of described mozzle and right-hand member, be provided with to the check valve of the described trichloro-ethylene rinse bath direction circulation of right-hand member; Between the described trichloro-ethylene rinse bath of left end and described cleaning fluid recovering mechanism, be provided with to the check valve of described cleaning fluid recovering mechanism direction circulation; Between described trichloro-ethylene rinse bath, be provided with from the right groove check valve that groove circulates successively left.
The utility model arranges alcohol rinse bath by one end of the some trichloro-ethylene rinse baths being arranged side by side, can more easily thick film circuit be cleaned successively in trichloro-ethylene-alcohol-trichloro-ethylene, first thick film circuit being put into trichloro-ethylene rinse bath removes the residue of overwhelming majority printing, welding etc., then by the alcohol in alcohol rinse bath and the dirty generation cementation of the fingerprint on thick film circuit, remove, finally through trichloro-ethylene rinse bath, washing out the remaining dirty of surface.The utility model, by increasing alcohol rinse bath, make better effects if, the thick film circuit of cleaning more clean, and technical parameter remains unchanged under wet environment, and then has improved circuit performance stability and the reliability of thick film circuit.
The utility model can be at the cleaning fluid recovering mechanism of trichloro-ethylene rinse bath rear end, to used trichloro-ethylene cleaning fluid distill, cooling, and by the check valve between mozzle and trichloro-ethylene, will distill cooled clean trichloro-ethylene cleaning fluid and flow into successively in trichloro-ethylene rinse bath, so that trichloro-ethylene cleaning fluid is fully used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, trichloro-ethylene rinse bath, 2, alcohol rinse bath, 3, cooling-part, 4, cleaning fluid recovering mechanism, 5, mozzle, 6, check valve, 7, supersonic generator, 8, the groove of heating.
The specific embodiment
As shown in Figure 1, the utility model includes: three trichloro-ethylene rinse bath 1(are arranged side by side from left to right by the numbering of I, II, III), an alcohol rinse bath 2, a cleaning fluid recovering mechanism 4, is crossed with at trichloro-ethylene rinse bath 1 and alcohol rinse bath 2 upper ends the automatic delivering mechanism (not shown) that thick film circuit board is transmitted.Automatic delivering mechanism can adopt conventional circuit board conveyer structure.
Wherein, three trichloro-ethylene rinse baths 1 and an alcohol rinse bath 2 are arranged side by side: three trichloro-ethylene rinse baths 1 are in left side, and alcohol rinse bath 2 is on right side.The supersonic generator 7 being respectively arranged with in trichloro-ethylene rinse bath 1 and alcohol rinse bath 2 and the groove 8 of heating.
Cleaning fluid recovering mechanism 4 be arranged on left end trichloro-ethylene rinse bath 1 after, the inside is provided with cooling-part 3, for used trichloro-ethylene cleaning fluid is distilled, cooling and reclaim.Between the trichloro-ethylene rinse bath 1 of cleaning fluid recovering mechanism 4 and right-hand member, be connected to mozzle 5, between mozzle 5 and cleaning fluid recovering mechanism 4, be provided with to the check valve 6 of mozzle 5 direction circulations, between mozzle 5 and rightmost side trichloro-ethylene rinse bath 1, be provided with to the check valve 6 of rightmost side trichloro-ethylene rinse bath 1 direction circulation.
