Description
Technical field
The utility model relates to a kind of double-contact continous way multi-segment voltage electrophoresis control circuit.
Background technology
The electrophoretic coating production line that current production rate is large adopts segmentation voltage continuous electrophoresis mode, compare one section of voltage continous way electrophoresis quality to increase, but the workpiece of double-contact can't realize two-part cathode section electrophoresis at present, part producer is in order to head it off increase secondary hanger, make double-contact into single contact, increase cost, and output can be reduced because of workpiece size change.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of double-contact continous way multi-segment voltage electrophoresis control circuit, and it has the features such as automaticity is high, efficiency is high, cost is low.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: comprise two rectifiers and export two groups of DC voltage, jointed anode pipe after two cathode output end parallel connections of two groups of DC voltage, two cathode output ends of two groups of DC voltage connect the negative electrode of multiple thyristor respectively, the wherein control pole connection control device of thyristor, realizes double-contact continous way multi-segment voltage electrophoresis.
The utility model improves further and is: controller can export and to start and stop signal delivers to low-voltage rectifier, realize workpiece not charged enter groove, soft raising voltage electrophoresis after entering groove, minimizing workpiece electrophoretic surface washmarking, the problem such as ripple, shrinkage cavity, improves the quality of products.
The beneficial effect adopting technique scheme to produce is: compare double-contact one section of electrophoresis mode, improves electrophoresis product quality; Compare double-contact increase secondary hanger and change single contact mode, improve production capacity, reduce production cost, increase work efficiency.
Therefore, this circuit meets control at double-contact continous way multi-segment voltage electrophoresis completely.Solve change single contact costly, problem that production capacity is low, improve the utilization factor of paint line, improve electrophoretic painting quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of major loop in the utility model;
Fig. 2 is the control principle block scheme of Fig. 1.
Embodiment
From the embodiment shown in Fig. 1-2, comprise two cathode output ends that two rectifiers export DC voltage, two output terminals connect the negative electrode of thyristor respectively, the anode of thyristor connects direct current and exports the compositions such as copper bar, the wherein control pole connection control device of thyristor, realizes double-contact continous way multi-segment voltage electrophoresis.High-low pressure two rectifier output cathodes connect electrophoresis tank inner anode pipe, low pressure negative pole 1-is by 1VD1,1VD2,1VD3 ... 1VDn is connected to first, second, third of low pressure respectively ... and final stage copper bar, high voltage negative 2-is by 2VD2,2VD3 ... 2VDn is connected to second, third of low pressure respectively ... and final stage copper bar, high voltage negative 2-is directly connected to the negative copper bar of high pressure.
principle of work
This circuit is completed by segmentation controller process, can according to the spacing of the speed of carrier chain detected, the length of workpiece and installation, calculate workpiece two contacts and divide other position, when contact is to first copper bar below, workpiece soaks electrophoresis tank entirely, give and start boost signal, to the trigger pip of thyristor (1VD1), comprise interior all low-voltage thyristor trigger pips according to Workpiece length to length; Low-voltage cabinet automatically soft be raised to operating voltage, along with carrier chain advances, segmentation controller can open the trigger pip of the corresponding thyristor of next section of copper bar in advance in conjunction with the current signal detected, next section of copper bar operating voltage is made to be set to low pressure, when rear point leaves first paragraph copper bar completely and arrives second segment copper bar, close the trigger pip that first paragraph leads to board thyristor (1VD1); After low-voltage electrophoresis time arrives, when needing boosted voltage electrophoresis, open the IGBT group signal of corresponding copper bar, realize the transition of high-low pressure no-spark.
