Novel coating pretreatment electrophoresis process and coating pretreatment electrophoresis equipment

Abstract

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 reduced by the relative motion of the workpiece and the nozzles; and when the process control is simplified, the aim for solving the problems of overlarge spray generated in the transmitting process and a cleaning blind area existing in the spray process of the current self-propelling hoist is achieved.

Description

technical field [0001] The invention relates to a pre-painting electrophoresis process and equipment using a self-propelled gourd, in particular to a pre-treatment electrophoresis line process and equipment conveyed by a self-propelled gourd with a spraying process. Background technique [0002] With the continuous development of coating technology, new coating processes and equipment emerge in an endless stream, and it is very economical to use self-propelled hoist transportation when the production capacity is lower than 18JPH. At present, the self-propelled gourd transportation mostly adopts the intermittent production method, and the spraying treatment and dipping treatment stations are all used to stop the operation, vertically lift and then swing at a certain angle to process the workpiece. There is another way that the workpiece is sprayed on the tank, but the workpiece is in a static state during the spraying process. Although these two methods can meet the process ...

AI Technical Summary

Problems solved by technology

Although these two methods can meet the process requirements of treatment, in the process of equipment design, in order to be able to clean the entire workpiece, it is necessary to configure a lot of nozzles, which will lead to an increase in the amount of spraying, an increase in operating costs and equipment construction costs, and at the same time intermittent There is a lack of relative movement between the spray workpiece and the nozzle, so there will be a certain cleaning blind area on the surface
