Coating pretreatment and electrophoresis test device for continuous annealing and galvanized steel sheet

The invention provides a coating pretreatment and electrophoresis test device for continuous annealing and galvanized steel sheet, which comprises a degreasing test box, a phosphorization test box, a washing test box, a surface conditioning test box, a zirconization test box, a silane test box, a pure water washing test box, an electrophoresis test box, a control device, an identification module, a rotating device, a tray and a manipulator; the identification module, the rotating device and the manipulator are all electrically connected with the control device, and the tray is connected with the rotating device. The process test can be automatically carried out to avoid the influence of the technical level of an operator on a test result, and the process environment of pretreatment and electrophoresis treatment carried out by an automobile manufacturer and a home appliance main engine plant in a workshop is accurately simulated, so that an accurate test result can be obtained; and manufacturers of continuousl
