Novel coating pretreatment electrophoresis process and coating pretreatment electrophoresis equipment

The invention discloses a novel coating pretreatment electrophoresis process and coating pretreatment electrophoresis equipment. The equipment comprises a chamber, a lifting mechanism, a travelling mechanism, a lifting appliance and a spray system. The equipment is characterized in that the spray system comprises a spray pipe, a water pump, a spray groove and a water running plate; when driving aworkpiece to enter a spray pipe area, the lifting appliance slowly travels; a plurality of nozzles are arranged on the spray pipe and controlled by a PLC to spray; and spray groove liquid is recoveredin the spray groove by the water running plate. The invention changes a traditional idea of a pretreatment electrophoresis line transmitted by a self-propelling hoist, favorably combines a continuousway and an intermittent way and sprays and leaches in the process of travelling; the travelling direction of the workpiece is perpendicular to the spray direction of the nozzles, and the arrangementnumber of the nozzles is red
