Electrophoretic coating system

Abstract

The invention discloses an electrophoretic coating system. The electrophoretic coating system comprises a rust removal device and an electrophoresis device, wherein the rust removal device comprises amounting rod, and a pneumatic telescopic rod is fixed to the lower end of the mounting rod; the lower end of a rod body of the pneumatic telescopic rod is fixedly connected with a rotating motor, anda rotating shaft of the rotating motor extends into a metal net cylinder; the center of a bottom plate of the metal net cylinder is fixedly connected with a positioning protruding edge through a connecting rod, and the connecting rod and the positioning protruding edge are inserted into a connecting groove and a positioning groove in the bottom end of an output shaft; a plurality of brush wires are fixedly connected to the inner wall of the metal net cylinder, and a fixing block with a rectangular section is fixedly connected to the lower end of a bottom plate of the metal net cylinder and used for being inserted into a fixing hole of a rust removal liquid cylinder; the section of the fixing hole is rectangular, and the rust removal liquid cylinder is filled with rust removal liquid; therotating shaft of the rotating motor is sleeved with an upper lantern ring and a lower lantern ring, and clamping devices are welded to the two sides of the lower lantern ring; and each clamping device comprises a mounting plate and a lower clamping plate, each mounting plate is screwed by at least two screws in a threaded mode, and the lower end of each screw is fixedly connected with an upper clamping plate.

Description

technical field [0001] The invention relates to the technical field of electrophoretic coating, in particular to an electrophoretic coating coating system. Background technique [0002] Electrophoretic coating is a coating method that uses an external electric field to make the particles such as pigments and resins suspended in the electrophoretic liquid directional migrate and deposit on the substrate surface of one of the electrodes. The principle of electrophoretic coating was invented in the late 1930s, but it was developed This technology was applied in industry after 1963. Electrophoretic coating is a special coating film formation method developed in the past 30 years. It is the most practical construction process for water-based coatings. It is water-soluble, non-toxic, Easy automatic control and other characteristics, it has been widely used in industries such as automobiles, building materials, hardware, and home appliances; [0003] Before the electrophoretic coa...

Problems solved by technology

[0003] Before the electrophoretic coating, the workpiece often needs to go through pretreatment processes such as degreasing and rust removal to ensure that the surface of the workpiece meets the standards during electrophoresis. Electrophoretic coating method When the workpiece is electrophoretic coated, the workpiece will be directly taken out for drying after electrophoresis in the electrophoresis tank. The drying chamber and the electrophoresis tank are separated and independent. The required distance is longer, and dust fibers are easily attached to the surface, which leads to poor electrophoretic coating effect of the workpiece, which easily leads to an increase in the rejection rate of the electrophoretic coating of the workpiece, and affects the efficiency and effect of the electrophoretic coating of the workpiece.
