Embodiment Construction

[0015] See attached figure 1 , the present invention includes an electrophoretic coating process for coating electronic parts, a radium engraving process for engraving electronic parts, an etching process for graphic processing of electronic parts coatings, and an etching process for electronic parts. The stripping process for detaching the coating of the parts also includes a waste water recovery process, and the waste water recovery process is used to recycle the waste water generated in the electrophoretic coating process, etching process, and film stripping process.

[0016] The electrophoretic coating process is connected to the numerical control system and is automatically controlled by the numerical control system. The combination of numerical control technology and electrophoretic coating process realizes the fully automatic production of electrophoretic coating process.

[0017] See attached figure 2 , the technical process of the electrophoretic coating process des...

Abstract

A novel etching process for coating and etching a metal workpiece relates to the etching of a metal part. The process comprises an electrophoretic coating procedure for coating an electrical part, a laser etching procedure for carving the electrical part, an etching procedure for graphic processing of the coating of the electrical part, and a film removing procedure for removing the coating of the electrical part. The process further comprises a wastewater recycling procedure for recycling wastewater generated in the electrophoretic coating procedure, the etching procedure, and the film removing procedure. The above described electrophoretic coating procedure is connected with and is automatically controlled by a numerical control system. The novel etching process has beneficial effects that the process setup is reasonable, multiple times of washing reduce solution residual in different procedures, the resulting product has no out-of-shape decoration and has high precision.

Description

[0001] technical field [0002] The present invention relates to etching processing of metal parts. Background technique [0003] Etching refers to removing the protective film of the area to be etched after exposure to plate making and development, and contacting chemical solution during etching to achieve the effect of dissolution and corrosion, forming the effect of concave-convex or hollow molding. The existing etching production line is too complicated, with many processes and unreasonable process settings. Due to the excessive use of chemical raw materials, not only the production cost is increased, but also the environmental protection is affected. Contents of the invention [0004] The purpose of the present invention is to provide a new process for coating radium engraving and etching of metal workpieces. The process setting is reasonable and the residue of liquid medicine on the metal workpieces in different processes can be reduced. [0005] In order to achiev...
