Technical Field

[0001] The utility model relates to the technical field of back pole plate coating processing, in particular to a pretreatment mechanism of a coating device for back pole plate processing. Background Art

[0002] Microphone products are widely used in electronic products such as headphones, conference systems, mobile phones, computers, etc. As consumers have higher and higher requirements for sound, electret microphones and back plates as their main accessories have emerged. The main manufacturing process is to composite FEP film after surface treatment of metal substrate (generally nickel plating). The metal substrate serves as a conductor and the film serves as an insulating layer with dielectric properties. The electret charge on the film, the consistency and stability of the electret charge will have an important influence on the sensitivity of the microphone sound. Initially, the back plate products were made of sheet materials and coated, which could not meet the higher market requirements. Especially with the rise of major short video platforms, various application scenarios have higher and higher requirements for sound fidelity and clarity, and higher quality back plate products are needed to meet market demand.

[0003] The existing back plate does not clean the metal substrate during the coating process, resulting in dust and other impurities on the surface of the metal substrate that affect the coating effect. Therefore, the utility model provides a pretreatment mechanism for a coating device for back plate processing to solve the above-mentioned problem. Utility Model Content
